information, the FCC registration number and ringer equivalence number (REN) for this equipment.
If requested, this information must be provided to the telephone company.

The REN is used to determine the quantity of devices which may be connected to the telephone line.
Excessive REN’s on the telephone line may result in the devices not ringing in response to an
incoming call. In most, but not all areas, the sum of the REN’s should not exceed five (5.0). To be
certain of the number of devices that may be connected to the line, as determined by the total REN’s
contact the telephone company to determine the maximum REN for the calling area.

An FCC compliant telephone cord and modular plug is provided with this equipment. This
equipment is designed to be connected to the telephone network or premises wiring using a
compatible modular jack which is Part 68 compliant.

This equipment cannot be used on telephone company-provided coin service. Connection to Party
Line Service is subject to state tariffs.

If this equipment causes harm to the telephone network, the telephone company will notify you in
advance that temporary discontinuance of service may be required. If advance notice is not practical,
the telephone company will notify the customer as soon as possible. Also, you will be advised of

 1.2 System Description

1 System Overview
...................................................................................................

Coral System General Features

The Coral FlexiCom 6000 is a digital, hot standby, redundant, communications switching
system. The Coral system is based on Pulse Coded Modulation (PCM) switching
technology. The active circuitry of the system is contained on removable printed circuit
assemblies, or cards, nearly all of which may be used in any system in the family.
The active circuitry of the Coral system is divided into two major functions: Common
Control and Peripheral. The Common Control circuitry directs call traffic through the
system, establishing audio connections between Peripheral ports.
The Peripheral circuitry provides the hardware necessary to establish those connections.
Instructions from the Common Control circuitry to the Peripheral circuitry, and status
information from the Peripheral circuitry to the Common Control circuitry are passed
through the Group Controller, which is considered neither Common Control nor
Peripheral.
The peripheral circuitry is further divided into Shared Service and Peripheral Interface
functions. The Shared Service circuitry provides the equipment necessary to establish
calls between Peripheral interfaces. The Peripheral Interface circuitry provides
standardized electrical connections to external telephone station equipment and network
facilities.

Coral FlexiCom 6000 Redundancy

The Coral FlexiCom 6000 system is a non-stop, non-blocking operation. The
System Description

Coral FlexiCom 6000 Hot Standby dual control option includes two complete sets of
control hardware, each able to fully and independently control the operations of the entire
system. The two sets function interchangeably, making it possible for either set to take
over control functions automatically in the event of malfunction to any portion of the
control system. Administrators can manually intervene as needed and activate the switch
over from one control system set to the other to carry out routine maintenance, as well as
reinstate the second control set in Standby mode. At all times, one control system is the
1

Active side, constantly providing active control operations.

Coral FlexiCom 6000 Installation Manual Introduction 1-3

 The changeover from the Active control system to the Standby control system is virtually
undetectable by the users. Each control system set is able to take over from the other at
any time, as needed without interrupting calls.
The Coral FlexiCom 6000 control design includes two independent power supplies units
(PS-ATS). They share the power needs of the complete control system while each Unit is
able to provide power independently to the entire control system in the event that one
malfunctions. An inoperative power supply unit may be replaced while the system is
operational.
The operating software, stored in the Compact Flash memory Disk (CFD) of both control
system sets, provides complete long-term stability. The Database program is stored in a
battery-protected SRAM in the appropriate components of both control system sets. All
generated data stored in the memory of the Active control system is automatically
recreated in the corresponding component of the Standby control system.
The Coral FlexiCom 6000/R (Redundant) Hot Standby dual control system provides
complete battery protected backup coverage.
The Coral FlexiCom 6000 system may also be used in a single control set configuration
without using the redundancy option.
Details about the system configurations can be found in Table 1-1 below.
The Coral Generic software—Version 14.x or higher, provided with the Coral FlexiCom
6000 system is used to update and configure the Dual control system or single FlexiCom
6000 system via the Program Interface.

 2 Hardware Design
...................................................................................................

The Coral FlexiCom 6000 system is built on a free standing, floor mount Main cabinet,
serving as the system’s foundation. Each system includes one main cabinet, which
contains the Control Shelf with either one control card or two control cards, depending on
whether it is a single or dual control system. The Main cabinet also includes 2 or 3
peripheral shelves which house the Power Supplies, the Universal I/O card slots and the
Shared Service Card Slots. One or more Expansion cabinets may be connected to house
additional Shared Service and I/O Card slots.
The Control Shelf includes one Control Card, the 32GC for a single system. The dual
system, FlexiCom 6000/R includes two 32GC cards, placed side by side on the same
control shelf. Other control accommodating cards also reside on the control shelf as well.
The FlexiCom 6000 systems can be housed in the standard 23 inch cabinets.
See Chapter 6 for further cabinet and card details.

3 Updating from the Coral FlexiCom 5000

...................................................................................................

The Coral FlexiCom 6000 system is easily accommodated into a standard Coral FlexiCom
5000 cabinet. Its size and dimensions are interchangeable with the Common Control shelf.
An upgrade kit must be purchased to upgrade from a Coral FlexiCom 5000 system to the
6000 system. Upgrade kits include a card cage, cables and instructions for the installation.

 2 Installation Environment
...................................................................................................

1. Verify that the installation area is clean, dry, and protected from weather extremes.
2. Verify that the floor of the installation area is finished with linoleum, vinyl,
ceramic, wooden flooring, or polished sealed concrete.

Carpeting is not acceptable.

3. Verify that the ceiling of the installation area is finished or treated to prevent
particle discharge and water damage.
4. Verify that the installation area is well lit, and that the light source is uniformly
diffused without shadows. Adequate lighting should provide a comfortable
reading level and allow the identification of wire insulator colors without undue
eye fatigue.
Lighting should be comparable to an office work environment, with a minimum
level of 70 foot-candles at each work surface. As a general rule, in a room with an
eight foot (2.5m) ceiling, one 48 inch fluorescent tube provides sufficient
illumination for 20-25 sq. ft. (1.9-2.4m2).
5. Verify that ventilation of the installation area is capable of maintaining an ambient
temperature of 32-104° F (0-40° C), and a relative humidity of 20-80%
non-condensing, while the system is operating as listed in Table 2-2.
These figures are for each cabinet only, and do not take into account heat
generated by other equipment. In particular, charging fully-discharged batteries
may generate a considerable amount of heat, depending on battery capacity and
rate of charge. Refer to the equipment manufacturer data for more information.
6. Verify that the installation area is free of caustic or corrosive liquids, substances, or
materials. If batteries will be installed as part of the system, ensure that adequate
precautions are taken (such as special ventilation) to prevent corrosive emissions
from the batteries. Check local building codes for additional requirements.
7. Verify that the installation area is located no closer than 20 feet (6.1m) from electric
devices which produce large electro-magnetic fields or high levels of radio
frequency energy. Possible sources are radio transmitters, electric arc welding
Site Inspection

machines, copying machines, electric motors, elevators, refrigeration units, power

transformers, electric load centers, and main circuit breaker panels.
2

Coral FlexiCom 6000 Installation Manual Hardware Installation Procedure 2-3

 8. Verify that the installation area provides reasonable security to the system. Room
construction should include solid, reinforced walls and a locking door.
The Coral system, and the service it provides to users, represents a substantial
investment. During an emergency, reliable service may be crucial in protecting
lives and property. Access to the system should be limited and controlled to
prevent unauthorized tampering. The system uses hazardous working voltages
and extremely high short circuit currents, and the area must be protected against
damage by, and injury to, unqualified personnel.

1. Verify that electrical service is sufficient and located in close proximity to the
system. The installation requires one dedicated branch circuit for the Coral system;
and one additional branch circuit minimum for ancillary equipment such as data
terminals or personal computers, external paging equipment, test instruments, etc.
Each branch circuit must be independently protected by fuse or circuit breaker,
and must not be controlled by a switch. C type fuses should be used where
required by local authorities.
The receptacle for the Coral system branch circuit must be located within 4 feet
(1.2m) of the 48 volt power supply for DC operated. Auxiliary branch circuit
receptacles should be located conveniently for ancillary equipment; and allow data
terminals, personal computers, or test instruments to be operated near the system.

Coral FlexiCom 6000 Installation Manual Hardware Installation Procedure 2-7

 10. Have two assistants each grasp one of the front casters at the bottom end of the
cabinet. The assistants should place their feet under the bottom edge of the
shipping pallet. Keeping arms and backs straight and lifting with their legs, have
the assistants carefully pull upward on the casters to lift the bottom of the cabinet
approximately 8 inches (20cm) off the shipping carton. Quickly pull the bottom
foam insert out from under the raised cabinet, while the assistants lower the
cabinet back onto the shipping pallet.
11. Move to the top end of the cabinet and with the two assistants (three persons
total) grasp the bottom of the shipping carton between the boards of the pallet.
Keeping arms and backs straight and lifting with your legs, lift the shipping
pallet, pivoting the pallet on the bottom edge. Continue lifting slowly until the
cabinet begins to slide down the inclined shipping carton. Allow the cabinet
casters to come to rest against the inside bottom of the shipping carton, then
continue to raise the pallet until its weight begins to balance on the bottom edge.
12. Have one assistant move to the open side of the shipping carton and push gently
on the cabinet to prevent the cabinet from tilting out of the shipping carton.
Continue to raise the shipping pallet until the cabinet is vertical. Have the second
assistant move to the open side of the shipping carton. Have the two assistants
reach around the cabinet and tilt it toward them, while you pull the bottom of the
shipping carton out from under the cabinet casters. Have the assistants return the
cabinet to vertical so that it rests on all four casters.
13. Carefully remove the plastic dust wrap from the cabinet.
14. Inspect the cabinet exterior for hidden shipping damage. Verify that the cabinet
doors open and close properly. Inspect the cabinet interior and contents for
shipping damage.
15. Verify that the leveling feet are retracted so that they are well clear of the floor. If
any of the leveling feet are extended, use a 17mm wrench to turn the locking nut
above the leveling foot clockwise, so that it comes down to rest at the top of the
leveling foot. Then spin the leveling foot anti-clockwise to retract it away from the
floor.

 2 Cabinet Mounting and Placement
...................................................................................................

1. Carefully roll the cabinet to the location where it is to be installed. When the
cabinet is rolled over carpeted floors — particularly hallways, check ahead of the
cabinet to be sure the weight of the cabinet does not create a wave or ripple in the
carpet. If a wave starts to form, stop rolling the cabinet and push the excess carpet
under the cabinet until the carpet is flat. As the cabinet approaches floor-to-carpet
transitions or expansion gaps in cement floors, roll the cabinet slowly and ease the
casters over the obstruction to prevent undue stress.

The cabinet leveling procedure below immobilizes the cabinet, and should
not be performed until the cabinet is stationary. If the installation environment
requires moving the cabinet during installation to gain access to the rear,
complete all communications and power wiring to the rear of the cabinet
before performing the leveling procedure.

2. Once the cabinet is in position, use a 17mm wrench to loosen the locking nut
above each leveling foot, by turning it clockwise, if necessary. Spin each of the
four leveling feet to the left, extending them to the floor. With the help of an
assistant, tilt the front top of the cabinet back slightly, and turn the front two
leveling feet one or two additional turns, so that the weight of the cabinet rests on
the leveling feet instead of the casters. Repeat this procedure for the rear two
leveling feet.
Place a carpenter’s level on the top of the cabinet and check the pitch left-to-right
and front-to-back. Adjust the leveling feet accordingly, and continue to check the
pitch until the cabinet is level. Turn the locking nut above each leveling foot to the
right until it comes to rest against the base of the cabinet. Tighten the locking nut
by using a 17mm wrench until snug.
3. Cut and remove the tie wraps holding the wooden retaining bars across the front
of the Common Control shelf. These bars will not be used again, and may be
discarded.
4. Check the alignment of all four doors on the cabinet to verify that the doors open
Equipment Installation

and close smoothly. Proper door alignment is essential to maintain shielding of the
cabinet from radio frequency interference (RFI).
The plastic bag containing extra cabinet hardware and cabinet placement
instruction includes 15 flat washers which may be placed over the hinge pin at the
bottom of each door. If a door does not align properly with the cabinet, push
down on the upper hinge pin release lever inside the door, tilt the top of the door
away from the cabinet, and lift the door off the bottom hinge pin. Several flat
2

washers already may have been placed over the bottom hinge pin to raise the

Coral FlexiCom 6000 Installation Manual Hardware Installation Procedure 2-9

 door. Add or remove flat washers as necessary to align the door. Re-install the
door.
5. Check the force required to close each door. The fit of each door is determined by
alignment to the opening and by the pressure applied by contact springs around
the door. The contact springs bond the door electrically with the cabinet, forming
a complete shield against electromagnetic and radio frequency signals. Each door
should fit snugly into the cabinet opening, however undue force should not be
required to open or close any door.
The edges of the doors are perforated at the corners to allow the edge to be bent
with relatively light hand force. Bending an edge of a door inward or outward
controls the pressure applied by the contact spring against the edge, and thus
contributes to the force required to open or close the door. To adjust the fit of a
cabinet door, grasp an edge of the door and bend it gently inward or outward as
necessary. Check the door fit and adjust the bend of each edge if required.
6. Check the interior of the shipping carton and remove any other remaining items.
7. Reassemble the shipping carton components and set the shipping carton aside.
Once the system is completely installed and operating, it is no longer necessary to
keep the shipping carton.

 3 Ground and Power Wiring
...................................................................................................

Electrical Hazard! Connect only a Protective Earth (PE) to the Coral system.
DO NOT connect a separate Telecommunications Reference Earth (TRC).
Resistance from the master ground to the building electrical ground should never
exceed 1.0 ohm. The master ground bar should be located in the switching room as
close as possible to the Coral. Any ground connection of equipment related to the
switching Coral system should ultimately connect to the master ground.

The manufacturer strongly recommends using a stranded three conductor

cable for the earth ground and DC power wiring, to minimize the inductance
of the current path. This cable should be jacketed or enclosed in a wire
conduit which meets local building, electrical, and/or fire codes.

Figure 2-2 illustrates a typical power wiring diagram for a single-cabinet. Figure 2-3
illustrates a typical power wiring diagram for two cabinets. Although two cabinets are
shown, the wiring is similar.
1. Power cables may be routed from above the Coral cabinet through a cable entry
point in the left rear corner of the cabinet top, or from below through a similar
entry point in the rear left corner of the cabinet bottom. Determine whether cables
will be routed from the top or bottom of the cabinet. Figure 2-4 illustrates the
possible power cable routing through the cabinet.
2. Release the two locking screws from the power input cavity and remove the cover
and retain it. Also remove the cable clamps and retain them, see Figure 2-5.
3. If the power cable is routed from the bottom of the cabinet, remove the two
circular covers through which the cables are to be routed. One is located on the
cabinet front-left bottom and the other on the cabinet top, behind the cable clamps.
Forcibly push up the covers, releasing them from their spring fixings and discard.

 Verify that the positive and negative power conductors are NOT connected to the
–48VDC power source or energized in any way. Route the power cable through the left
cable entry (as viewed from the rear) at either top or bottom, taking care not to let the
free end of the cable cause damage by swinging loose, making contact with another
electrical power connection, or striking the card connector pins on the cabinet
backplane.

4. If the cable enters the cabinet from above, leave approximately 18 inches (45cm) of
power cable at the top of the cabinet to reach the DC power terminals.
If the power cable enters the cabinet from below, route the cable through the
bottom port entry, and up along the left frame member of the backplane, using
cable ties through tie slots along the frame to secure the cable. Route the cable
through the port on the top of the cabinet behind the cable clamps. Figure 2-5
illustrates the power input cavity area. Let approximately 18 inches (45cm) of
power cable exit the top of the cabinet to reach the DC power terminals.
5. Carefully remove approximately 12 inches (30cm) of jacket from the power cable
to expose the insulated power and earth ground conductors.
6. Route the yellow/green earth ground conductor through the left (smaller) cable
clamp in the Cable Guide above the two SGND terminal lugs on the left side of
the Power Input Card in the power input cavity. The Cable Guide may be
removed to ease the insertion of the conductors into the power input cavity. see
Figure 2-5.
7. Route the red positive conductor through the right (larger) cable clamp in the
Cable Guide above the 48V RTN IN terminal lug on the Power Input Card in the
power input cavity.
8. Route the black negative conductor through the right (larger) cable clamp in the
Cable Guide above the –48V IN terminal lug on the Power Input Card in the
power input cavity.
Equipment Installation

9. Use a #1 (1/4”or 8mm) straight-blade screwdriver to tighten the three cables.

10. Use cable ties to secure each of the conductors to the Cable Tie-Off Bracket on the
top of the cabinet, leaving sufficient slack in each conductor to prevent strain.
11. Replace the Power Input Cavity Cover and screw into place.
12. Install the front and rear cabinet nameplates at the top of the cabinet front and
rear, respectively.
13. Continue with Input/Output (I/O) Cables beginning on page 2-17.

 4 Input/Output (I/O) Cables
...................................................................................................

Champ Connections
1. Input/Output (I/O) cables may be routed from above the Coral cabinet through a
cable entry point in the right rear corner (as viewed from the rear) of the cabinet
top, or from below, through a similar entry point in the right rear corner of the
cabinet bottom. Determine whether I/O cables will be routed from the top or
bottom of the cabinet.
If the top entry point is used, release the locking screw, remove the cover plate
and discard it.
If the bottom entry point is used, forcibly remove the cover plate and discard.
2. Determine the route of I/O cables from the MDF to the connectors on the
backplane at the rear of the cabinet. Measure the longest distance from an I/O
connector on the backplane to the corresponding cable punch block on the MDF.
3. Fabricate cables of the length determined above with a male 25 pair connector on
one end, for each I/O connector on the backplane. Thirty two 25 pair cables are
required for a Coral cabinet with 2 peripheral shelves and forty-eight cables are
required for a Coral cabinet with 3 peripheral shelves.
4. Carefully route the connector end of each I/O cable through the right cable entry
point at the top or bottom of the cabinet, threading the cable through the guide
rings along the right side of the backplane to each I/O connector, as shown in
Figure 2-6: Coral I/O Champ Cable Routes from Bottom of Cabinet (rear view) and
Figure 2-7: Coral I/O Champ Cable Routes from Top of Cabinet (rear view).
If I/O cables enter the cabinet from the top, route the first cable to the upper right

 RJ-45 I/O Cable Connections (LDF and UDF)
Input/Output (I/O) RJ-45 cables for LAN/WAN/PSTN/router/LTU/CSU/etc. are
routed from above the Coral FlexiCom 6000 cabinet through three cable entry points in
the rear upper section of the cabinet. See Figure 2-9 and Figure 2-10.
RJ-45 cables routed from the front panel of the peripheral interface cards must be
connected via the LDF or UDF panels. Verify that the RJ-45 cables are not connected
directly from the LAN/WAN/PSTN to the connectors on the front panel of Coral
peripheral cards. Route the cables through the I/O RJ-45 cable entry opening at the rear
top panel of the cabinet.

The LDF (LAN Data Filter) and the UDF (Universal Digital trunk Filter)
incorporate improved RFI immunity. These filters enable the Coral and all
relevant peripheral interface circuits to be fully protected against
radio-frequency interference (RFI) and meet or exceed all requirements and
specifications of telecommunications and electrical safety authorities
world-wide.

1. Remove the rear decorative panel nameplate on the top of the cabinet. See Figure
2-11.
2. Route the crossover cable (Catalog Number 7244-8000624) from the front panel of
the peripheral cards to the lower connections of the LDF or UDF panel as shown
in Figure 2-9 and Figure 2-10.

It is imperative that a crossover cable (Catalog Number 7244-8000624) be used

 5 Power Supplies
...................................................................................................

Coral power supply units (PS-ATS, PPS and RPS) are heavy.
Handle with care and do not drop.

Verify that the Power Switch on the front panel of all the power supply units (PPS and
RPS) is in the OFF position, prior to insertion.

The Dual Hot Standby system for the Coral FlexiCom 6000 is supported by two redundant
PS-ATS power supply units supplying power for the control system. Each individual
PS-ATS unit can supply the power for the dual system. One PS-ATS can be removed,
replaced and inserted while leaving the other PS-ATS unity to supply the full power on
its own. This is referred to as “Hot Insertion”.

The power supplies used in the Coral FlexiCom 6000 operate from a
–48VDC source. The power supplies consist of one or two PS-ATS units in
the Common Control shelf, and up to two PPSs and an optional RPS ring
generator in each peripheral shelf. Refer to Figure 2-14 and Figure 2-12 for
power supply placement in the Common Control shelf and Peripheral
Shelves, respectively.

See Chapter 7, Power Supplies for further details on the PS-ATS units.

Installing the Power Supply Units

Two Power Supply Units are normally shipped in the Common Control Shelf of the
system already fastened into place. Verify that the two power supplies are installed in
Equipment Installation

slots PS2 and PS1 on the bottom corners of the control shelf. There is an empty third power
supply slot in the upper right hand corner (slot PS3). This slot is for future Coral
Configurations. Install the PPS and RPS units in their slots on the Peripheral shelves, if not
installed already.
1. To insert the PS-ATS Unit(s), if not already installed, grasp its handle with one
hand.
2

2-26 Hardware Installation Procedure Coral FlexiCom 6000 Installation Manual

 For the PPS and RPS, grasp the power supply with both hands, fingers on the top
and bottom of the power supply near the front panel, and thumbs against the
extractor levers at the top and bottom of the front panel.
2. Verify that the power supply is oriented correctly:

When installing the PS-ATS in either slot on the right side, in slots PS2 and PS3,
ensure that the Fail and Power LEDs are located at the top of the unit.

When installing the PS-ATS on the left side of the control shelf, in slot PS1,
ensure that the Fail and Power LEDs are at the bottom of the unit (i.e. install
the unit upside down).
3. Align the circuit card edges with the card edge guides in the card cage or shelf,
and gently slide the power supply straight into the card slot. A slight resistance
will be felt as the multi-pin connectors on the power supply meet the mating
connectors on the backplane and engage.
4. Push the power supply PS-ATS into its slot (for the PPS and RPS, push against the
extractor levers) until the front panel of the power supply is flush with the front
frame of the card cage. Force the power supply into the slot. If increased resistance
is encountered, remove the power supply and examine the connectors for bent
pins or interfering debris.
5. Fasten the four captive screws on each corner of the unit.
Before the first initialization of the system, before the power-up tests are
administered (Power Supply Test beginning on page 3-1), these units should be
partially extracted from their slots so that they protrude by approximately 1 inch
(2.5cm). Only after verifying the external power should they be reinserted
properly and fastened.

PPS and RPS Placement

The Peripheral Power Supply (PPS) and the Ringer Power Supply (RPS) are
shipped in the Peripheral Shelves as required.

In some cases only a single PPS is required to supply power for the two Peripheral
shelves in a Peripheral Unit. Usually, two PPS are installed, one either on the odd
or even shelf. If two PPSs are installed on the even shelf, and an RPS is needed, it
Equipment Installation

can be housed on the odd shelf. Verify whether a single RPS is sufficient for the
two shelves, see below.

The RPS power supply is required only in systems in which single-line telephone
(8SLS, 16SLS, 24SLS or 16SH/S-LL cards) or magneto telephone (8SM card) station
circuits are installed. The first RPS is installed on the even Peripheral shelf. In
most cases only a single RPS is required to supply power for the Peripheral shelf
Unit, although a second RPS may be installed on the odd Peripheral shelf when
needed.

 6 Circuit Card Installation
...................................................................................................

Circuit cards contain static-sensitive circuitry and may be damaged or destroyed by

electro-static discharge (ESD). Always wear the static dissipating wrist strap connected
to the system cabinet or card cage while handling circuit cards. Hold circuit cards by
their edges and avoid touching contact surfaces. Handle with care and do not drop.
Failure to observe safe handling procedures for static sensitive circuitry may result in
permanent damage to a card.

Inserting a Coral Circuit Card

To insert a circuit card into a card slot, grasp the card with both hands, fingers on the edge
of the card near the front panel and thumbs against the extractor levers at the top and
bottom of the front panel. Verify that the card is oriented correctly. Align the edges of the
circuit card with the card edge guides in the card cage or shelf and gently slide the card
straight into the card slot. A slight resistance will be felt as the multi-pin connectors on the
circuit card meet mating connectors on the backplane and engage. Push against the
extractor levers until the front panel of the card is flush with the front frame of the card
cage. Do not force the circuit card into the slot. If more than slight resistance is
encountered, remove the circuit card and examine the connectors for bent pins or
interfering debris.

Shared Service and Peripheral Interface Card Installation

The Peripheral Cards are shipped separately from the cabinets. Remove them from their
packaging and design the card placement as described below. Gently slide the cards into
their slots while allowing them to protrude by about one inch (2.5cm) from the card cage.
These cards will be inserted completely after the Power-Up tests performed in Chapter 3.
Equipment Installation

Some Shared Service and Peripheral Interface cards may require changes
to option straps on the card which determine the electrical characteristics or
operation of each interface circuit. Refer to specific card descriptions in Coral
Service and Peripheral Cards Installation Manual, for details.
2

2-28 Hardware Installation Procedure Coral FlexiCom 6000 Installation Manual

 Peripheral Card Placement
Peripheral Interface cards may be installed in any universal I/O slot of the Coral system.
However the following considerations must be taken into account to ensure the efficient
and smooth operation of the Coral system.
Card slots 1 and 2 of each Peripheral Shelf in the Coral cabinet can accept either a PB-ATS
(Peripheral Buffer) or Shared Service card. (The PB-ATS cards are placed only on
Peripheral shelves defined as even shelves, see Odd or Even Shelves on page 6-27).

PB-ATS:
To prevent inserting a PB-ATS card in the wrong slot, the PB-ATS card is
contoured differently than the other Peripheral Shelf cards. It has rounded
corners similar to the control cards of other Coral systems.
The PB-ATS card slides into matching groves in slots 1 and 2.

Card slots 3 through 18 are Universal I/O slots, accepting any Shared Service or
Peripheral Interface card type.

Determine the position of Shared Service and Peripheral Interface cards that are to
be inserted into card slots 1 through 18. Observe any order previously directed by
a System Designer or any established convention of the distributor. The Card
Placement Diagram, Figure 2-12 for Even Numbered Shelves and Figure 2-13 for
Odd Numbered Shelves, may be used as a worksheet by the System Designer to
establish card placement prior to installation. Refer to Table 2-5 to determine
Shared Service and Peripheral Interface card types.

Two PB-ATS cards are installed in Slots 1 and 2 of every even Peripheral Shelf,
see Odd or Even Shelves on page 6-27.

Shared Service cards, see Table 2-5, can be installed in Slots 1 and 2 of every
odd numbered peripheral shelf.

Distribute trunk interface cards (4ALS, 8ALS, 8BID, 8DID, 4GID, 4T, 8T,
4/8T-C, 4/8T-CID, 4TEM, 4TMR, 4TPF, 8TPF, DPC, 4TBR, 8TBR, 30T, 30T/x,
PRI23, PRI30, UDT and T1) evenly among all peripheral shelves in the system,
rather than concentrate trunk interface cards in one or two shelves. This
practice ensures that the failure of a single peripheral shelf has minimal impact
Equipment Installation

to trunk service.

In cabinets with three Peripheral shelves (48 card slots), place all single-line
and magneto ports (8SLS, 16SLS, 24SLS, 16SH/S-LL and 8SM cards) on even
numbered peripheral shelves if possible, so that an RPS (Ringer Power Supply)
is not required on the odd numbered peripheral shelf.
If no other convention exists, plan the card placements as follows:

Insert PB-ATS cards in card slots 1 and 2 of each even numbered peripheral shelf.
2

Coral FlexiCom 6000 Installation Manual Hardware Installation Procedure 2-29


Insert Shared Service cards in card slot 1 and 2 of each odd numbered peripheral
shelf.

If synchronization is required, the first two Digital Trunk Interface cards must be
placed in card slot 4 of two even numbered peripheral shelves in the Main
cabinet. The cards inserted in these slots are used to synchronize the Coral system
clock with a network clock signal via a Digital Trunk Circuit, as they are wired as
the primary and secondary external clock source, respectively. Refer to the Coral
Synchronization via Digital Trunks section in the Coral Service and Peripheral Cards
Installation Manual, for more information on synchronization.

Place Peripheral Station Interface cards starting at slot 3 and moving to the right
(omitting slot 4 if synchronization is required).

Place Peripheral Analog Trunk Interface and remaining Auxiliary and Digital
Trunk Interface cards starting at card slot 18 and moving to the left.

Distribute heavy consumer cards (cards with a large number of ports) among the
slot sets as evenly as possible, based on their PCM highway distribution, see Time
Slot Distribution among the Peripheral Units on page 6-23. The Peripheral Shelf Unit
timeslots are divided into four groups of 128 timeslots among its 36 slots. These
cards are least blocking when placed in Peripheral Shelf Units that contain only an
even numbered shelf.

For a completely non-blocking system, the technician should avoid installing

the following cards in slots 1-8 of peripheral shelves 6 and 7:
30T/x, T1, PRI24, PRI 30, IPG and UGW.

2-32 Hardware Installation Procedure Coral FlexiCom 6000 Installation Manual

 Common Control Card Installation
The Coral FlexiCom 6000 includes a single set of common control cards, always located
on the right side of the shelf, while the FlexiCom 6000/R includes two redundant sets of
control cards.
The FlexiCom 6000/R includes two sets of control cards that stand side by side on the
same shelf. Each control set has seven slots. The control cards on the right side are
duplicated on the left side in reverse and upside down order. Each side consists of the
following card slots placed in this order from the middle outward:

32GC (with the SAU interface)

CLA-ATS (Optional)

FMSD (for CLA-ATS- Optional)

MCP-ATS

FMSD (for MCP-ATS Optional)
The cards installed on the right side of the shelf are inserted with the card LED at the top.
The cards installed on the left side of the shelf are inserted up-side down, with the card
LED at the bottom.

Preparing the Control Cards for Installation

1. The standard FlexiCom 6000 Common Control cards are normally shipped already
inserted in their respective card slots. Upon removing the packaging of the
Control cage, verify that these cards are indeed inserted into their respective card
slots as shown in Figure 2-14.
2. Partially extract each card from its card slot, so that the cards protrude from the
card cage approximately 1 inch (2.5cm). See Extracting Control Circuit Cards below. The
cards will be inserted into place after the Power-Up tests described in Chapter 3 are
successfully completed.

Extracting Control Circuit Cards

To extract a circuit card from its card slot:
Equipment Installation

1. If there are screws in place at the top and bottom of each card, release the screws.
2. Grasp the injector/ejector levers on the top and bottom of the card’s front panel,
with one hand on the top lever and the other hand on the bottom lever.
3. Gently press the levers outward toward the top and bottom of the card. The card
is released from the connections to the backplane.
4. Extract the card from its slot.
For initial installation, partially extract each card from its card slot, so that the
2

cards protrude from the card cage approximately 1 inch (2.5cm).

Control Card Slots

Never force the insertion of a Common Control card in a slot other than the
one designated for that card. Irreparable damage may occur if a Common
Control card is placed in an incorrect slot with power applied.

Inserting Control Cards

The Coral Control shelf is shipped with the 32GC(s), the MCP-ATS(s), and the Power
Supply Unit(s) already set in their appropriate slots and fastened into place. The CLA-ATS
is shipped separately and must be installed separately, see Card Installation on page 8-68 for
the installation procedure for the CLA-ATS card.

All the control shelf cards must be partially extracted from the Control Cage
before system initialization.

 7 Cabling between the Control and Peripheral Shelves
...................................................................................................

The 32GC is the heart of the FlexiCom 6000 system. A physical connection must be
constructed between the single 32GC or both 32GC cards and each peripheral shelf, odd
or even. The even peripheral shelves must have a hard-wire connection between the
PB-ATS cards and each 32GC card. These connections are implemented via FC-19 cables
between the 32GCs piggybacked backplane card, the MPG-ATS and the PB-ATSs
backplane card, the PBD-ATS. The odd shelves make their connection to the MPG-ATS via
a PBD24S (located on the backplane of the odd shelf) connected to their related PBD-ATSs
on the even shelf via FC-18 cables. See Figure 2-15 for a wiring schematic.
The arrangement of these connections define the Shelf numbering mainly used for the
Programming Interface Updates and Displays. See Peripheral Shelf Numbering beginning on
page 6-27 for Shelf Numbering Descriptions.
Main Cabinets (i.e., containing a Control Shelf) are shipped with factory installed cabling
between the main cabinet peripheral shelves and the Control Shelf.
The technician is required to wire the Peripheral Shelves from the other cabinets to the
Control Shelf. The hard wire connections are described below.

 MPG-ATS to PBD-ATS Connections
The MPG-ATS piggyback card on the Control Shelf backplane provides two sets of
connectors for each of the Peripheral Shelf Units. Each set contains connectors marked:

P1 to P8 corresponding to the 32GC installed on the right side of the Control
Shelf. These are wired to P3 of each PBD-ATS.

P9 to P16 corresponding to the 32GC installed on the left side of the Control Shelf.
These are wired to P2 of each PBD-ATS.

Wiring between the MPG-ATS and PBD-ATS

1. Locate the even shelves that have not yet been connected to the MPG-ATS by
searching for unconnected PBD-ATS cards on the system backplane. At least one
FC-19 cable is required for each even shelf.
For Hot Standby systems (i.e. two 32GCs are installed on the Control Shelf), two
FC-19 cables are required for each even shelf not yet connected.
2. Connect one side of a FC-19 cable to the next free MPG-ATS P1, P2,..., P8
connector by pushing it onto the pins until the connector locks onto the pins.
If this is a Hot Standby system, connect another FC-19 cable to its Pn pair
(between P9 and P15) that has the same Unit number as the first.
The MPG-ATS connectors are paired as follows:
P1 and P9: Unit 0 P5 and P13: Unit 4
P2 and P10: Unit 1 P6 and P14: Unit 5
P3 and P11: Unit 2 P7 and P15: Unit 6
P4 and P12: Unit 3 P8 and P16: Unit 7

For a completely non-blocking system, the manufacturer recommends

connecting Unit 3 (P4 and P12) only for systems with more than 14 shelves.
Additionally, the technician should avoid installing the following cards in
slots 1-4 of Peripheral Unit 3 (shelves #6 and 7) in the Coral FlexiCom
6000: 24SLS, 24SDT, 24SFT, 30T/x, T1, PRI24, PRI 30, IPG and UGW.

3. The MPG-ATS card is surrounded by ground leads for each Pn connector. Connect
Equipment Installation

the FC-19 ground wire to the closest GNDn lead, see Figure 2-17.
4. Connect the other side of the first FC-19 cable to the next available PBD-ATS P3
connector until locked into place.
If this is a Hot Standby system, connect the other side of the second FC-19 cable to
the same PBD-ATSs P2 connector.
5. The PBD-ATS has ground leads for the FC-19 cables. Connect the ground wire to
the closest GNDn lead on the PBD-ATS for each P2 and P3 connection, see Figure
2

2-18.

2-36 Hardware Installation Procedure Coral FlexiCom 6000 Installation Manual

 When connecting the MPG-ATS or PBD-ATS Pn cables, always ensure that
each Pn connector has its ground wire attached to the closest available
ground lead, GNDn, see Figures 2-17 and 2-18.

PBD-ATS to PBD24S Connections

The odd peripheral shelves (those containing no PB-ATSs) are connected to the 32GC via
their respective even shelves (those containing a PB-ATS). The odd shelf is connected to
the even shelf via a FC-18 cable on the shelves backplanes, see Odd or Even Shelves on page
6-27 for determining odd and even shelves.
1. Locate the PBD24S cards not already connected to an even shelf. One FC-18 cable
is required for each card.
2. Connect one side of the FC-18 cable to J1 on the PBD24S by “locking” it onto the
card pins.
3. Connect the other side of the FC-18 cable to P1 on the even shelf above or below
this shelf, see Figure 2-16.
4. Repeat this procedure for each “unconnected” odd shelf.

 2.3 Program Interface Device Connection

1 Device Connection
...................................................................................................

The Program Interface (PI) is a detailed, menu-driven, interface system for programming
the Coral FlexiCom System. It also provides access to the diagnostic facilities contained
within the system software.
The PI can be accessed through any of the following types of connecting devices:

video display data terminal

keyboard send/receive (KSR) printer data terminal

a data terminal and modem

PC with VT emulator

PC with CoralVIEW Designer (CVD)

PC with CoralVIEW Administrator (CVA)

The Program Interface (PI) menu driven interface enables the technician to update the
system software backup and restore the system database and view system components as
needed.

Program Interface Device Connection

The PI terminal device (PC or data terminal) must be equipped with an
RS-232 asynchronous serial data interface which can be configured for a
data rate of between 300 to 115,200 bps (default: 9600), 8 data bits, 1 stop
bit and no parity bits.
The PI device must use the ASCII character set.
The earth ground connection to the PI device must be the same earth
ground connection supplied to the Coral system.

1. If the system is to have a dedicated PI device left on-site permanently, unpack this
device and prepare it for operation. Set the interface for a data rate of 9600 bits per
second, 8 data bits, 1stop bit, and no parity bit. (These are the default settings for
all serial programming ports of the Coral system.) The data rate of the KB0
programming interface is set automatically by the PI at 9600 bps.
2

2. Determine the connector type and pin assignments for the data interface of the PI
device. Most data terminals use a 25 pin DB-25P (male) or DB-25S (female)

Coral FlexiCom 6000 Installation Manual Hardware Installation Procedure 2-41

 connector, with pin assignments as shown in Figure 2-19. Most personal computers
use a DB-25P or DA-9P connector for the serial interface, with pin assignments as
shown in Figure 2-19 or Figure 2-20.
3. Obtain or prepare a serial data cable to connect the PI device to the KB0 serial
programming port on the front panel of each MCP-ATS card. The KB0 port end of
the serial programming cable requires a male DB-25P style connector, wired as
shown in either Figure 2-19 or Figure 2-20.
If the PI device uses a DB-25P or DB-25S connector, wire the connectors according
to the diagram in Figure 2-19. If the PI device is a personal computer equipped
with a DA-9P connector, wire the connectors according to the diagram in Figure
2-20.
4. Route the serial data cable from the PI device to one of the cable entry ports in the
top or bottom left rear of the cabinet. Lace the serial data cable together with other
cables entering the cabinet. Pass the end of the serial data cable from the rear of
the cabinet to the front by placing the connector on the rear of the sloped
reinforcement bar between the cabinet side panel and the card cages, and letting
the end of the cable slide down the incline to the front. Leave approximately 24
inches (60cm) of cable on the front side of the cabinet to reach the front panel of
the MCP-ATS card installed on the Common Control shelf without interfering
with the insertion or removal of any circuit cards or power supplies.

 3.1 Power Supply Test

1 General
...................................................................................................

This Chapter provides information about initial tests that must be performed when first
installing a Coral FlexiCom 6000 system.
Use a Digital Multi-Meter (DMM) to perform the following voltage measurements.

In the following tests, no measured voltages should be zero. If a zero (0)

voltage reading is shown, check the meter settings and verify that the leads
are connected properly. If, after checking the meter and connections, a zero
voltage reading remains, the associated power supply is faulty and must be
replaced.

Before proceeding, verify that all internal power supplies (PPS, RPS and PS-ATSs) and
circuit cards in the Coral system are only partially inserted into their respective card
slots, with the front panels protruding approximately 1 inch (2.5cm) from the front of the
card cage.
Also, turn off all peripheral Power Supplies: PPS and RPS units. These are to be
switched on only after at least one Control Shelf PS-ATS is powered.

...................................................................................................

Connecting the External Power Supply

1. Turn ON the external 48VDC power supply or battery charger and close any fuse
or circuit breaker required to supply 48VDC to the Coral cabinet.
2. Measure the voltage entering the Power Input terminals located in the upper left
corner of the rear of the cabinet. Connect the positive lead of the DMM to the 48V
RTN IN terminal and the negative lead to the -48V IN terminal. The reading must
be approximately +48 volts DC. Refer to Figure 3-1.

If a minus sign (–) appears in the meter display, the polarity of the 48VDC power to the
cabinet is reversed. Verify the meter settings and connections. If the meter is properly
set and connected, carefully examine the wiring between the external 48VDC power
supply and/or batteries, determine the location of the polarity reversal, and correct the
wiring error before continuing.

3. Place the power input cover over the power input cavity. Refer to Figure 3-1.
4. Insert the two screws into the power input cover and tighten them.
5. Push the front and rear decorative panels into place.
6. Repeat the above steps for each Coral cabinet in the system.

...................................................................................................

If the start-up tests detect that the voltage level of a lithium back-up battery on the 32GC
or the 4/8XMM card is insufficient to reliably maintain the memory contents in the event
of power failure, the following messages are displayed on the PI terminal.

A Low Battery message indicates that the database should be saved and the batteries
replaced at the first possible opportunity.

If any of the above messages appear at any time, the system database is in jeopardy of
being lost during a power failure to the Coral system.

To ensure that the system database is not lost, copy the system database to the CFD card,
via the Database Controls (Route: ROOT,0,10,2,0,0) branch of the system database. See
Saving the System Database on page 4-4. The database copying process takes up to one minutes
Common Control Test

to complete. Should the system lose power or reset for any reason and the database be lost
from memory, the system will copy the database from the CFD into the system database
memory as the system restarts.
Once the system database is safely stored on the CFD, power to the Coral system may be
turned off at a time that will provide the minimum interruption of service to the user. At
that time the card battery (or batteries) may be replaced, and the system restarted. Verify
that the CFD is installed in the MCP-ATS as the system starts, so that the system can read
the database from the diskette back into database memory.

 3.3 Shared Service &
Peripheral Interface Card Test

Handling Procedures - Each card contains circuitry which is sensitive to electrostatic

discharge (ESD). Failure to observe safe handling procedures for static-sensitive
circuitry may result in permanent damage to a card.
Note that there is an anti-static wrist strap at the top of the cabinet above the card cage.
This wrist strap should be worn while inserting, removing, or handling any card in the
system.

Before proceeding, verify that all the PPS and RPS units in the Peripheral Shelves are
turned off.

After the software has been installed and initialized:

1. Check the position of Shared Service and Peripheral Interface cards that will be

Shared Service & Peripheral Interface Card Test

inserted into the system card cage. Observe any order previously directed by a
System Designer or any established convention of the distributor. Use the Card
Placement Diagram, as described in Peripheral Card Placement beginning on page 2-29.
2. Turn on the PPS and RPS units in each peripheral shelf.

Turn on the PPS and RPS units only after powering the Control Shelf and verifying that
the Control Shelf has initialized properly, otherwise the cards in the peripheral shelves
may not initialize.

3. Insert the cards fully, one by one, similar cards in adjacent card slots, so that the
installation takes a logical appearance with a uniform Numbering Plan (i.e., the
first line card fully inserted is assigned the first available line numbers by the
3

Numbering Plan).

Coral FlexiCom 6000 Installation Manual Initial Power-Up Tests 3-19

 Gently slide the card straight into the card slot. A slight resistance is felt as the
multi-pin connectors on the circuit card meet mating connectors on the backplane
and engage. Push against the extractor levers until the front panel of the card is
flush with the front frame of the card cage. Do not force the circuit card into the
slot. If more than slight resistance is encountered, remove the circuit card and
examine the connectors for bent pins or interfering debris.
4. The red diagnostic LED on the front panel (near the top of the card) should
illuminate on all cards. The LED remains illuminated steadily until the card
receives a card database from the system. After a few seconds, the LED should
extinguish. The extinguished diagnostic LED indicates that the card has been
properly initialized.
If the LED remains on steadily for more than two or three minutes, either there is
a conflict with the system database or the card may be faulty. Refer to the Coral
Service and Peripheral Cards Installation Manual for further details on LED
indication.
5. Attach the Program Interface (PI) device cable to the KB0 programming port
connector on front panel of MCP-ATS if not already attached. The installation of
Shared Service and Peripheral Interface cards into a Coral system has considerable
impact on the system database. Refer to the Program Interface & Database Reference
Manual for more information. Using the PI, verify that each of the parameters
detailed below contain the appropriate information.
6. Verify that the cards are identified properly in the Card List (Route: CLIS) branch
of the system database. Both i_type and p_type fields should show the required
card name. In addition, an ACTIVE message in the status field indicates that the
card has been properly initialized. If the i_type field lists a different card type or a
CARD REPLACED message appears in the status field, then the card slot has been
Shared Service & Peripheral Interface Card Test

previously initialized by a different card type. That card must be relocated to a

clear card slot (i_type field shows NO_CARD) or the current card slot assignment
must be cleared. To clear the card slot assignment, remove the card from its slot,
enter NO_CARD in the i_type field, then reinsert the card and verify that it
initializes as described above.
A status field display of NO_RESOURCES indicates that the system Sizes are
insufficient to support the card.
A status field of UNAUTHORIZED indicates that there are not enough SAU ports.
The different card slot messages are described below in Table 3-1. For a complete
list of card slot status messages, see Chapter 6 in the Program Interface & Database
Reference Manual.

 4.1 Generic Feature Software

1 Introduction
...................................................................................................

The Coral FlexiCom 6000 is delivered to the site with the Coral Generic software already
factory loaded on the Compact Flash Disk(s) located on the MCP-ATS card(s).
The generic software database for the Coral FlexiCom 6000 is saved on a battery backed
up RAM located on the 32GC card. The Compact Flash Disk (CFD) installed in the
MCP-ATS (two identical CFDs are stored in both MCP-ATSs for the Hot Standby system)
holds the non-volatile copy of the database.
For preparing or upgrading generic Coral software, CFD disks can be loaded with
appropriate software and authorizations using the FMprog Utility. For more information
about the FMprog Utility, see the FMprog Utility Reference Manual.
The software initialization procedure is described in Common Control Test beginning on
page 3-9.
The CFD is a 64MB Flash Memory card that contains three types of data:

Generic Feature Software Version and Boot Code

Authorization

Database Backup
The CFD card can be updated by a PC terminal using any PC 3.5” disk slot PCMCIA
application adapter and by using the FMprog tool. This procedure is used for loading new
Coral software versions onto the CFD.
Whenever an updated version of the Coral FlexiCom 6000 software is released, the
upgrade is delivered to the sites either on 3.5” diskettes, CD, e-mail, or via other electronic
Generic Feature Software

media file transfer. The upgrade is contained in a self-extracting compressed file, specific
for the site.
The FMprog is a tool for Coral dealers that install, upgrade and maintain Coral systems
using flash memory cards. For more information on the FMprog application, see the
FMprog PC-Utility Reference Manual which describes how to install and operate the
FMprog-Utility.

 2 Upgrading the CFD card with FMprog
...................................................................................................

Upgrading the Coral generic feature software involves three main steps:
1. Installing the FMprog-Utility (version 4.xx and later) on a PC.

Use FMprog version 4.xx and later. Otherwise, the Coral will not initialize.

2. Extracting the new Coral generic feature software file into the PC hard disk.
3. Saving the new generic software upgrade from the PC to the CFD card.
The FMprog-utility is used to backup the Coral’s software into a PCMCIA CFD type card.
The backup file is written in a binary format and includes all the software components of
the specific Coral system from which it was copied, i.e. the Coral generic software version,
the switch authorization and the database. The manufacturer highly recommends storing
a copy of the current files located at each customer site. Copies should be made per
customer site since each site has its unique set of software configurations, such as its main
software version, switch authorization and database, as well as specific Software
Authorization Unit (SAU) information. Should it be necessary to reinstate or copy system
files, copies of all the system’s files exist and are available for use via the FMprog-Utility.

Use the FMprog-Utility to:

Manage the new database versions

Load Coral Generic Versions, Authorization, and Database information onto the CFD

Extract Version, Authorization and Database information from source files.

Upgrading the Coral Generic Version

After a CFD has been programmed with a new or upgraded software version, the Coral
Generic Version may be upgraded.
To upgrade the Coral generic version, the CFD must be installed when the power to the
system is shut down. For Hot Standby systems, identical CFDs must be installed in each
Generic Feature Software

side of the Control Shelf in each MCP-ATS, after which power may be returned to the
system.
See Upgrading the Coral Version on page 4-21 for details.

Creating a Binary Backup of the Database

Before installing a CFD card with a new generic software version, it is strongly
recommended to create a binary backup of the database. The binary backup must be done
4

by a PC using the Binary Backup PC-Utility. The Binary Backup is a tool for Coral
technicians who install, upgrade and maintain Coral systems.

4-2 Software Installation Procedure Coral FlexiCom 6000 Installation Manual

 4.2 System Database Control

The generic software database for the Coral FlexiCom 6000 is saved on a battery backed
up RAM located on the 32GC card. The Compact Flash Disk (CFD) installed in the
MCP-ATS (two identical CFDs are stored in both MCP-ATSs for the Hot Standby system)
holds the non-volatile copy of the system database, the generic software and feature
authorization. Therefore, when a database system restore is needed, it is restored from the
CFD to the system RAM on the 32GC card.
During normal system operation, the configuration database may be saved to a file on the
CFD for permanent storage. The system also may be programmed to save the database to
the CFD automatically on a daily basis, at a particular time. The CFD is capable of storing
up to 64MB of information.
A saved database file may be loaded at any time into the system’s database memory. This
is a good way to copy the database of one system into another, to change the system
configuration, or restore the database into the RAM of a new 32GC memory card.
For more detailed information, consult Chapter 21 of the Program Interface & Database
Reference Manual.

...................................................................................................

The Database Control Branch of the PI allows the technician to manipulate the DB0/DB1
files stored on the CFD as well as to define the automatic backup time and frequency.
1. Establish a PI programming session by entering a PI password.
2. Select the Database Disk menu (Route: ROOT, 0, 10, 2, 0) branch:

DISK-MENU

1-EXCHANGE DB0/DB1 (Not Used)
2-LOAD DBS
3-COPY FILES
4-SHOW DIR
5-UPDATE VERSION (Not Used)
6-AUTO BACKUP

*:

Saving the System Database

Use the 0-Save Database Option to copy the current system database (from the 32GC
RAM), at any time, to the CFD card for backup or restore purposes. For Hot Standby
systems, this option may only be requested from the Active side. The database is copied
to both flash memories simultaneously. After a successful Save, each PI Terminal reports
which database was saved successfully. If the database was not saved successfully, a PI
Alarm message is displayed on the PI terminal(s).

The SAVE procedure is only possible from the Active side of a Hot Standby
system. However, messages indicating a successful copy appear on both
system sides.

1. Verify that the system time and date are correct (press Control-T to check). Update
System Database Control

through the Time and Date branch (Route: TIME) of the system database, if
necessary.
2. From the Database Control Branch: Disk Menu (Route: 0, 10, 2, 0), press 0 to save
the database to the CFD(s). The system prompts for the selection of a destination
file number, either DB0.DEF or DB1.DEF, with:

DEST FILE #(0,1) -

The DB0.DEF file is used for automatic saves at a preset time each day (see
4

Automatic Daily Database Back-Up on page 4-10), and is usually a more updated file than

4-4 Software Installation Procedure Coral FlexiCom 6000 Installation Manual

 the DB1.DEF file. The DB1.DEF file is referred to as the technician copy of the
database, and should be saved each time installation or maintenance personnel
make changes to the database.
3. Press 0 or 1, according to Table 4-1 below, to choose to which file to save, DB0.DEF
or DB1.DEF. The default entry is 0 (DB0.DEF).

Table 4-1 CFD File

Descriptions Database File PI File Description
Name Entry

DB0.DEF 0 Daily back-up automatically at a preset time.

DB1.DEF 1 Technician copy for manual back-up.

At the system prompt the following parameter is displayed:

EXECUTE (Y/N) -
4. Press Y to execute the Save Database command.
In a Hot Standby system, messages for both system sides appear on the Active
side’s PI terminal, when the database process is completed. The same message is
displayed on the Standby side:

Active Side Message: DBS stored to DB1.DEF.

Standby Side Message: DBS stored to DB1.DEF.
Executing a Save Command may take from a few seconds to a few minutes.
Therefore, changes to the system configuration (such as changing the system to
Night Service) cannot be completed during the save operation until the database
save process is completed.
Press N to cancel and return to the Database Disk menu. The PI command prompt
(*:) immediately returns, however the system processes the command as a
background (low priority) task.

Coral FlexiCom 6000 Installation Manual Software Installation Procedure 4-5

 Loading (Restoring) the Database from the CFD
A system database stored as a file on the CFD can be loaded into the database RAM
memory of the Coral system (on the 32GC card) at any time, with a system restart. For Hot
Standby systems, this procedure is executed only from the Active side, however, the Load
is performed on both system sides.
Loading a database stored on the CFD can be useful for installing the database of an
existing system into the database memory of another system that has a substantially
similar configuration. Similarly, a database can be created by programming a system
off-line at another location — perhaps at the distributor’s facilities, then loaded at a
convenient time at the intended site.

Loading a database from a CFD file into the database memory destroys the original
database information stored in the database memory and overwrites it with information
from the CFD database file. Once overwritten, the original database cannot be
recovered.

1. From the PI Database Control Branch: Disk Menu (Route: 0, 10, 2, 0), press 2 to
load the new database. The system prompts to select a source disk file number,
either DB0.DEF or DB1.DEF with:

FILE # -
2. Press 0 or 1, according to Table 4-1 above, to choose which file to load.
The system prompts:

EXECUTE (Y/N) -
3. Press Y to begin loading the database from the CFD, or press N to return to the
Database Disk menu. Loading the database from the CFD file generally takes a
few seconds to a few minutes depending on the system size.
After the database is loaded, the system performs a Partial Initialization and
begins processing calls.

4-6 Software Installation Procedure Coral FlexiCom 6000 Installation Manual

 Copying Files on the CFD
The Copy Files option copies one database file to the other, in effect, copies DB0.DEF to
DB1.DEF, or vice versa. This may be desirable after making substantial changes to the
system configuration, so that the technician copy and the daily back-up copy of the
database are identical.
Copying the file from one to the other is preferable to saving the database twice, since
making changes to the system database are not prohibited during the copy process. Note
that the copy process cannot be used to copy a database file from one Flash card to another
- only from one file to another on the same Flash card.

The copying procedure is only possible from the Active side of a Hot Standby
system. However, messages indicating a successful copy appear on both
system sides.

1. From the Database Control Branch: Disk Menu (Route: 0, 10, 2, 0), press 3 to copy
one database file to the other.
The system prompts for the selection of the method used to identify files to be
copied, by database file number (0 or 1) or by file name, with:

0-DATABASE
1-SELECT FILE

*:
While either method may be used, using the database file number method is
highly recommended and is the only method discussed here.
2. Press 0 to select the database file number method.
The system prompts for a source file number and destination file number, with:

SRC FILE # -
and

DST FILE # -
3. Enter 0 for the source file and 1 for the destination file to copy DB0.DEF to
System Database Control

DB1.DEF; or 1 and 0, respectively, to copy DB1.DEF to DB0.DEF.

At the system prompt:

EXECUTE (Y/N) -

Copying one database file to another destroys the original contents of the destination
4

file by overwriting it with the contents of the source file. The original destination file
cannot be recovered once it is overwritten.

Coral FlexiCom 6000 Installation Manual Software Installation Procedure 4-7

 4. Press Y to begin the database file copy process, or press N to return to the
Database Disk menu. The PI command prompt (*:) returns immediately, however
the system processes the command as a background (low priority) task.
Copying a database file generally takes a few seconds to a few minutes depending
on the system size, provided no other priority tasks are required of the Main
Processor. When the copy process is completed, the system reports:

DB0.DEF COPIED TO DB1.DEF (or vice versa)

 Viewing CFD Directory Details
A list, or directory, of the files stored on the CFD may be displayed to determine its
contents. The CFD contains several files, including a system configuration database and
other files unique to the particular installation. For a Hot Standby system, each system
side may request to view its own directory.
1. From the Database Control Branch: Disk Menu (Route: 0, 10, 2, 0), press 4 to
display the CFD file directory. The system prompts:

EXECUTE (Y/N) -
2. Press Y to display the list of files contained on the CFD, or press N to return to the
Database Disk menu. The PI command prompt (*:) returns immediately, however
the system processes the command as a background (low priority) task.
Reading the directory generally takes only a few seconds, provided no other
priority tasks are required of the Main Processor. Figure 4-1 illustrates a typical
CFD directory.

The directory display lists each file on the CFD. The FILE_NAME field identifies each file.
The VERSION field is a “store count” and indicates the relative age compared to other
files of the same type. The lowest version number indicates the most recent, or the latest
database file. The LAST_DATE and LAST_TIME fields indicate the last date (in
MM/DD/YY format) and time (in HH:MM:SS format) that the file was written on the
CFD. The FILE_STATUS field is valid only for database files, and indicates whether or not

 Automatic Daily Database Back-Up
The system configuration database can be automatically saved to the CFD file at a preset
time each day. Auto Backup is used to set the time of day that the system will
automatically save the database to the CFD each day. During automatic daily back-up, the
database is saved to DB0.DEF.

The Backup procedure can be requested only from the Active side of a Hot
Standby system. However, the Backup will be performed on both system
sides.

1. From the Database Control Branch: Disk Menu (Route: 0, 10, 2, 0), press 6 to set
the Auto Backup time. The system prompts with the following parameter:

NUMBER OF DAYS BETWEEN BACKUPS

2. Enter the number of days between automatic backups. For example, entering 1
causes the system to automatically backup the database every day. Entering 2
causes the system to automatically backup the database every other day.
The default is set to backup every week (every 7 days).
Enter N to disable the automatic backups and thus enable manual backups.
3. The next parameter prompts for the time of day to perform the backup:

SET AUTO BACKUP TIME:

Enter the time of day to automatically save the system database in 24-hour format.
Use 00:00 or 24:00 for midnight and 00:01 (or 24:01) to 00:59 (or 24:59) for times
between midnight and 1:00 a.m. The default time is 01:30, or 1:30 a.m.

The technician should choose a time when call traffic is lowest.

 4.3 Hot Standby Configuration Modes

1 Hot Standby System Side Definitions

...................................................................................................

The Hot Standby (HSB) Coral FlexiCom 6000/R system is a redundant dual control
system. One control is Active while the second remains in Standby mode. If the first
system fails for any reason, the second, Standby system, automatically becomes Active so
that there is no interruption of calls with this redundant system. The originally Active side
is transferred to FAUTLY mode. The faulty system continues automatic diagnostics and
will automatically recover if possible.
Both the Active and Standby controls are connected to the peripheral shelves while only
one connection is active (supplying all signals,e.g.: PCM, HDLC, Clock, and Sync). This
mechanism is driven by redundant 32GC cards with mirrored memory connected to an
ATS-BUS providing communication between the two MCP-ATS cards.

Inactive Control System

A control system becomes Inactive when the Active or Standby system either fails (Faulty
mode) or is manually transferred to the Maintenance mode. In Maintenance mode, the
system continues diagnostics tests, alarm activation for service calls, and reports faults to
the Active system.
An Active Control system is automatically transferred to Fault mode when diagnostics
determines the control system to be faulty. In this mode, the system continues performing
tests and might automatically return to Hot Standby operation when normal results are

Hot Standby Configuration Modes

observed.
The control system in Inactive Mode does not participate in the system operations and is
not in Standby mode if the Active system fails.
The Coral FlexiCom 6000 configurations shown in Table 4-3 are available for HSB systems
(i.e., systems with redundant 32GC cards). The technician may use the PI parameters in
the HSB Branch to switch the system side modes to conform with any of these
configurations. See the HSB branch in Chapter 21 of the relevant Program Interface &
Database Reference Manual for further details.

...................................................................................................

The Active side may be on the left or right side of the Control Shelf, as displayed in the
above table. All updates to the HSB system must be performed from the Active side. This
may be easily determined by viewing the screen of Root Menu on the PI Terminal. The PI
states which system side it is monitoring by displaying either ACTIVE, STANDBY,
MAINTENANCE or FAULTY. The physical Active system side is readily viewed from the
32GC card front panel indicators for Active, Standby, Faulty or Maintenance, see 32GC
Front Panel on page 8-42. This information can also be viewed from the HSB branch of the PI.

 4.4 Upgrading the Coral Version

Upgrading the Coral Version halts all call processing. Therefore, only perform an upgrade
when call traffic and importance is lowest (usually during the late night or evening
hours).

To Upgrade the Coral Version:

1. Save the system database to a file on the Compact Flash Disk (CFD), see Saving the
System Database on page 4-4, above.
2. Turn off the main power to the switch for all the cabinets.
3. Turn off all the PPS and RPS units in each peripheral shelf.
4. Remove the MCP-ATS (for Coral FlexiCom 6000R (HSB) systems, remove both
MCP-ATSs) by unscrewing and pulling them out, see Installing/Removing the MCP-ATS
on page 8-39.
5. Replace the new CFDs in each MCP-ATS.
For HSB systems, ensure that exactly the same Coral generic version is loaded on
both CFDs. Additionally, ensure that the number on the SAU device exactly
matches the number on the CFD installed on the same system side. The SAU
numbers for the two system sides are not identical, therefore it is important to
verify that each side has its own set of identical SAU numbers.
6. Return the MCP-ATSs to their appropriate slots and screw into place,
see Installing/Removing the MCP-ATS on page 8-39.
7. Connect the corresponding SAU device to the front panel of the 32GC on the same
side of the Control Shelf.
Upgrading the Coral Version

For HSB systems, repeat this step for both SAU devices.

The generic feature software contained in the CFD is coded to function with one unique
SAU, which must be installed on the front panel of the CORRESPONDING 32GC card.

8. Return Power to the system, by first supplying the main power to the cabinet and
4

then turning on the peripheral power supply units (PPS and RPSs) in each of the
peripheral shelves.

Coral FlexiCom 6000 Installation Manual Software Installation Procedure 4-21

 9. Verify that the Coral is loaded properly by viewing the CCS on the air
message with the new Version number, see Messages for a Properly Loading Active Side
beginning on page 3-12 and Messages for a Properly Loading Standby Side beginning on
page 3-14 when the Standby side exists.
Verify that no SAU fault messages appear during the loading process, see SAU
System Faults on page 8-52.

The Coral system automatically ceases call processing after 14 days for any of the
following reasons:

The SAU serial number does not match the corresponding CFD SAU serial number.

The Coral generic version contained in the CFD is higher than is authorized by the SAU.

An SAU is removed from the 32GC front panel.
Relevant system messages appear on the PI automatically warning that the system will
not operate without the proper SAU.

10. The new CFD card(s) do not include a backup of the current database. To make a
backup of the database, perform the procedure described in Saving the System
Database on page 4-4.
11. In order for the Coral FlexiCom 6000R system to function as a Hot Standby
system, both MCP-ATSs must have the same Coral generic version loaded on their
CFD cards. Otherwise, the system is not in Hot Standby mode and automatically
reverts to a single sided system, where one side is Active, while the other side is
Faulty and does not operate.

Hot Standby systems require the same Coral generic version loaded on both system
sides. Otherwise, the system functions as a single sided system with no redundancy!

 Cabinet Components

Card Cages/Shelves
The Coral FlexiCom 6000 slot cabinet contains three or four card cages, also referred to as
shelves. These cabinets are designed to provide a simple, reliable method for installing
and removing the printed circuit cards and assemblies, which contain the active circuitry
of the system.

Cabinet Doors
Locking doors on the front and back of the cabinet provide physical protection to internal
equipment while still allowing access to the interior. There are door latches on the front
and rear cabinet doors. The latch is moved from the locked to the unlocked position by
inserting a screwdriver blade into the cylinder slot and turning the appropriate direction
until the latch is opened or closed.

Figure 6-3 Coral

FlexiCom 6000 Cabinet

6000
Door Latch Operation
Detail LOCK UNLOCK

Card Slots
Each card cage consists primarily of a metallic frame assembly and a printed circuit board,
referred to as a motherboard or backplane. Guides at the top and bottom of the card cage
align the cards and assemblies, during their insertion, with multi-pin connectors mounted
on the backplane. The guides and associated connectors comprise a card slot.
The connectors provide metallic paths from the cards to the various power and signal
busses of the system and in the Peripheral Shelves, to the Input/Output (I/O) connectors.

Control Shelf
The Control Shelf is located at the bottom of the Main Cabinet and houses all the control
cards as well as the system Power Supply Units (PS-ATS) and their fuses. A fan tray with
three fans, is located at the bottom of the shelf. Fuses for each fan are easily accessible from
Cabinet Descriptions

the front panel of the shelf.

The Control Shelf may house either one or two specific sets of Control Cards, side by side.
One set of Control Cards, always on the right side, indicates a stand-alone system as
illustrated in Figure 6-5.
Two sets of Control Cards indicate a FlexiCom 6000/R Hot Standby - Redundant system
where the set on the right controls the ACTIVE side, while the set on the left controls the
6

STANDBY side as illustrated in Figure 6-6.

Each Control Card has its own designated slot where no other card may be physically

Coral FlexiCom 6000 Installation Manual Cabinet Descriptions 6-3

 inserted. Special coded keys are placed on the top and bottom slot guides to prevent the
insertion of the wrong card in the wrong slot. The coded keys may be viewed in the
illustration shown in Figure 6-4. See Control Shelf Slots on page 6-5 for further details on the
Control Shelf Slots.

Peripheral Shelves
The Peripheral Shelves (or card cages) house the peripheral and ringer power supplies,
shared service cards, peripheral interface cards and PB-ATS cards. The main cabinet may
house a maximum of 3 peripheral shelves. Each expansion cabinet can house a maximum
of 4 peripheral shelves.

Shelf Positions
The shelf positions are denoted as the first, second, third or fourth cabinet shelves from
the bottom up. Therefore, the bottommost shelf is the first shelf, which, in the main
cabinet, is the control shelf, see Figure 6-7.

Peripheral Shelf UNIT Definition

The FlexiCom 6000 system defines up to two peripheral shelves as one Peripheral Shelf
UNIT (with regard to system time slots). Each Unit must include at least one PB-ATS card
on one of the shelves (which supplies 512 time slots to the Unit-either one shelf or two
shelves). The shelf that houses the PB-ATS card is defined as the even shelf, while the
other shelf in the Unit is defined as the odd shelf.

Control Shelf Slots

The Control Shelf houses the control cards. Each slot labels the specific card that must be
installed in that slot. The cards on the left side are installed upside down.
Each side consists of the following card slots labeled from the middle outward (see
Figures 6-5 and 6-6):

The Common Control Cards on either side are each allocated their own individual slots.
These cards can only be inserted in their designated slots. Each slot track is equipped with
three keys each on the top and bottom slot tracks, which define the unique slot,
see Figure 6-4. These keys prevent the insertion of the wrong card in a control shelf slot.

Three slots are provided for Power Supply units (PS-ATS), indicated in Figures 6-5 and 6-6
as PS1, PS2 and PS3. Two PS-ATS units are installed. While each of the two PS-ATS units
is independently capable of supplying the full power needs of the Control Shelf, the two
PS-ATS units share the supply of +5 volts power exclusively to that shelf.
The third power supply slot is in place for future configurations.
Power Supply fuses are located in the upper left corner. An extra fuse is supplied on the
side of the Control Shelf. The Fan tray and three fan fuses are located at the bottom of the
Control Shelf. See Chapter 7 for further details about the Power Supply Units.
See Chapter 8 for details about the Common Control Shelf cards.

 3 Input/Output Champ Connections
...................................................................................................

I/O connections to the system are established via 16 female 25 pair connectors on the rear
of the motherboard on each peripheral shelf. Figure 6-13 illustrates the Coral FlexiCom
6000 slot cabinet as viewed from the rear. I/O connections are only provided for Universal
I/O slots (slots 3-18). Mating male plugs should be industry standard, Amphenol®,
AMP™ or equivalent.

Upper and Lower Connectors

Eight of the I/O connectors are mounted on the Peripheral Shelf motherboard above the card
cage and are referred to as the upper connectors. The remaining eight connectors are mounted
on the motherboard below the card cage and are referred to as the lower connectors.

Odd and Even Slots

Each Universal I/O slot is referred to as an odd or even slot corresponding to the location
of its wire pairs in the associated upper and lower I/O connectors. Card slot to cable pair
relationships are identified in Table 6-2.

Card Slot to I/O Connector Relationship

The I/O connections for each card slot are divided between two I/O connectors, one
upper and one lower. Twenty four wire pairs total for each card slot.
Each card in an odd slot is allotted 16 wire pairs on its corresponding upper I/O connector
and 8 wire paris on its corresponding lower I/O connector.
Each card in an even slot is allotted eight wire pairs on its corresponding upper I/O
connector and 16 wire pairs on its corresponding lower I/O connector.
Thus, each I/O connector provides half of the I/O connections for two card slots. Pair 25
on each I/O connector is not used. Figure 6-14 and Table 6-3 identify the card slot to I/O
connector relationships.
Figure 6-15 illustrates the layout of the I/O connection for any pair of odd and even
Universal I/O slots as they appear on industry standard 66 type punch blocks.
Cabinet Descriptions

Refer to the specific card tables in Chapter 5-External Connections in the Coral FlexiCom
300, 400, 5000 Installation Manual for I/O connector pin assignments. There are no I/O
connector pin assignments for the PPS or RPS power supplies, Common Control cards or
Shared Service cards.

 Circuit Cards Placement Design
All Peripheral card slots (#3-18) are universal and can be used with both Peripheral and
Shared Service cards. However, in order to reduce errors and standardize the installation
procedure, a Coral system convention has been established.
Place 4TBR, 8TBR PRI23, PRI30, T1, 30T, or 30T/x digital trunk interface cards in slot #4 of
Peripheral Shelf #0 (the Primary synchronization slot) or slot #4 of the Upper Peripheral
Shelf (the secondary synchronization slot). These slots have been pre-wired for operation
as the primary and secondary external clock sources. Refer to the Coral Shared Service and
Peripheral Cards Installation Manual.
Place station cards in the shelf starting with slot #5 and continue placing them to the right.
Place Trunk cards in the shelf starting with slot #17 (shelf #0) or slot #18 (the Upper shelf)
and continue placing them to the left.
Slot #18 in shelf #0 is traditionally reserved for the 8DRCM or 8DRCF cards.

 5 Peripheral Highway Cabling
...................................................................................................

The Peripheral Bus of the Coral FlexiCom 6000 system is extended from the MPG-ATS
backplane card in back of the Common Control Shelf to the PBD-ATS card on the
backplane of the even numbered Peripheral Shelves (see Odd or Even Shelves on page 6-27) via
one or two redundant multi-conductor FC-19 cables. The redundant cables serve the Hot
Standby dual control system. Each cable provides the connection for one of the control
card sets.
The MPG-ATS card and PBD-ATS cards are daughter boards installed on each respective
backplane to facilitate the interconnections. The MPG-ATS is located behind the 32GC
card slots of the two control system sets positioned in the middle of the Common Control
Shelf backplane. The PBD-ATS is installed on each even peripheral shelf behind the
PB-ATS cards. The PBD24S is installed behind slot 1 of each odd peripheral shelf. The odd
shelf is connected to the even shelf via a FC-18 cable connection, this indirectly connects
the odd shelf to Control Shelf.
Two redundant FC19 cables carry the system’s high-level data link control (HDLC)
highways, the pulse code modulation (PCM) streams and all the Clock and Sync signals
from the control card to the PB-ATS cards for the Peripheral Shelf Unit.
The Clock signal is used to identify the bit period of the HDLC and PCM highways. The
Sync signal is used to identify the beginning of time slot 0 on the PCM highways.

Time Slot Distribution among the Peripheral Units

The 32GC card supports eight HDLC highways and thirty-two PCM streams where each
stream supports 128 times slots (64 for highway A and 64 for highway B), see Figure 6-18.
The number of streams allows the 32GC to support up to 8 Peripheral Shelf Units which
can house a maximum of 16 peripheral shelves. The time slots are supported via the
PBD-ATS which feeds off the PB-ATS card (2 PB-ATS cards for the Hot Standby system are
redundant -only one card broadcasts the 512 time slots).
Connectors for cabling to support both control card sets appear on the MPG-ATS, at
connectors P1 to P16. MPG-ATS connectors P1 to P8 carry the signals from the first 32GC.
MPG-ATS connectors P9 to P16 support the redundant cabling for the second 32GC card,
when installed. Each Peripheral Shelf Unit (an even, or even and odd shelf) is allotted 512
Cabinet Descriptions

time slots divided into four groups of 128 time slots. Figure 6-18 illustrates the PCM
highway distribution for a Peripheral Shelf Unit consisting of two shelves. The same PCM
highways support the odd and even peripheral shelf of the same Unit.

PCM highway A4 supports cards 13 to 18 in both even and odd shelves.

If only one shelf existed, the 512 time slots would be divided only among the
6

even shelf thereby enhancing call traffic.

 6 Tips for Peripheral Card Distribution
...................................................................................................

When installing a new Coral FlexiCom 6000 system, it is recommended to take into
account the timeslot (PCM highway) distribution among the peripheral shelf slots when
planning the peripheral interface cards location.
Each Peripheral Shelf Unit (even and corresponding odd shelf, or only even shelf) is
supplied with a total of 512 time slots between a maximum of 36 card slots. The timeslots
from the PB-ATS card, are evenly divided to 4 groups of 128 timeslots and distributed
between slot sets of each Peripheral Shelf Unit. The timeslot (PCM) distribution per slot set
can be seen in Figure 6-18.
To ensure efficient use of timeslots, it is recommended to distribute heavy consumer cards
(cards with a large number of ports: 30T/x, T1, PRI-30, PRI-24, IPG or UGW with MG-30
or MG-60 units) evenly among the slot sets, i.e. one heavy consumer card per slot set. The
least blocking sets are the slot sets that have the highest ratio of Number of Timeslots to
Number of Peripheral Slots in Table 6-4.

For a completely non-blocking system, the technician should avoid installing

the following cards in slots 1-8 of peripheral shelves 6 and 7:
30T/x, T1, PRI24, PRI 30, IPG and UGW.

Tip:
If a number of heavy consumer cards are to be installed in Peripheral Shelf
Units, determine which slot sets are least blocking by referring to Table 6-4.
Insert the first heavy consumer card in one of the slot sets, the next card in
the next least blocking slot set, etc.
When possible, avoid installing more than one heavy consumer card in a
single slot set.

 7 Peripheral Shelf Numbering
...................................................................................................

All Coral peripheral shelves are identical in terms of function. They each support the same
types of shared service and peripheral cards. Each peripheral card must be able to identify
itself to the control shelf. Therefore, the shelf number must be determined. The peripheral
shelves in the Coral FlexiCom 6000 are divided into Peripheral Shelf Units where each
Unit consists of one or two peripheral shelves that share at least one PB-ATS card. Each
Unit always includes an even numbered shelf, the shelf that houses the PB-ATS card(s).
The other shelf in the Unit, does not house any PB-ATS cards and is given an odd shelf
number.

Odd or Even Shelves

Peripheral Shelves are defined as odd or even, based on whether a PB-ATS card is
installed on the shelf. The Z5 and Z6 jumpers, located on the backplane of the PB-ATS
cards, and behind the PBD-ATS card, are set to reflect this even or odd shelf definition (see
Figure 6-19, for the Z5 and Z6 jumper definitions). The Coral FlexiCom 6000 system is
configured and delivered as per the customer request. Therefore, these jumpers are
factory set and there is no need to change them.
Figure 6-20 illustrates the Z5 and Z6 location on the backplane.

 Shelf Numbering
The peripheral shelves also have a logical even or odd address, i.e. Shelf #0, Shelf #1 up to
Shelf #15. These shelf numbers are used when updating Coral system information in the
Program Interface, CVD or CVA.

Even Shelf Numbering

The even shelf number is defined based its connection to the MPG-ATS card via the FC-19
cable from P3 (and P2 for a redundant system) of the PBD-ATS. The peripheral shelf is
defined as Shelf #0, 2, 4, 6, or 8 based on which P-connector the FC-19 cable is fastened to
on the MPG-ATS card, see Figure 6-21 and Table 6-5 to determine the shelf number.

For Example:
The shelf to which MPG-ATS: P1 (and P9 for redundant systems) connects, is numbered
Shelf #0:

P1 (MPG-ATS) connects to P3 on the PBD-ATS while P9 (MPG-ATS) connects to
P2 on the same PBD-ATS.

 Odd Shelf Numbering
The shelves with no PB-ATS cards installed on them, are defined as odd shelves and must
be connected to an even shelf (above or below) via an FC-18 cable, see Figure 6-24. The
FC-18 cable is connected between the PBD24S (located on the backplane of the odd shelf)
and P1 on the PBD-ATS of the related even shelf. Its Shelf number is defined as the even
shelf number +1. Therefore, the odd shelf connected to Shelf #0 is defined as Shelf #1, the
odd shelf connected to Shelf #2 is defined as Shelf #3, etc.

 8 Digital Trunk Synchronization
...................................................................................................

The Coral system uses two digital trunk cards as primary and secondary synchronization
sources. The system synchronization signals are carried through two H-43 cables. The
Coral FlexiCom 6000 system provides two additional synchronization connections, Third
and External which are not used.

Primary Synchronization Source Connection

The primary synchronization signal cable is connected between the P20 connector on the
MPG-ATS and the digital trunk card that has been chosen to be the Primary
Synchronization source via an H-43 cable. Conventionally, this Primary Synchronization
Source is a digital card located in Slot 4 labeled PRM SYNC of the peripheral shelf, however,
any digital trunk slot card is acceptable. P20 is connected to PIN 9 of the digital trunk card’s
backplane J-connector (i.e., behind the slot) which is J7 for slot 4, see Figure 6-25.

Secondary Synchronization Source Connection

The secondary synchronization signal cable is connected between the P19 connector on
the MPG-ATS and the digital trunk card that has been chosen to be the Secondary
Synchronization source via an H-43 cable. Conventionally, this Secondary
Synchronization Source is a digital card located in Slot 4 labeled SEC SYNC of the
peripheral shelf, however, any digital trunk slot card is acceptable. P19 is connected to
PIN 9 of the digital trunk card’s backplane J-connector (i.e. behind the slot) which is J7 for
slot 4, see Figure 6-25.
Refer to Coral Synchronization, in the Coral Service & Peripheral Cards Installation Manual
for further details.

Third and External Synchronization Source Connection

The Third and External synchronization source connections expand the system
synchronization capabilities. They are the P18 and P17 connectors, respectively. The
External P17 connector also may be connected to an external clock source.
Cabinet Descriptions

These connectors are not currently used.

Synchronization Connection Pins

The pin connections for each of the synchronization connections are especially designed
for longer life. Each pin connection is made up of four actual pins, divided functionally
into two pairs. The cable attaches to either the first and the third pins or the second and
6

fourth pins. If one of these delicate pins is damaged, the other pair remains functional.

 9 RPS/PPS Alarm Cabling
...................................................................................................

PPS and RPS alarm signals are passed via a wire cable from the RPS power supply slot on
the motherboard to the PBD-ATS card that services the Peripheral Shelf Unit in which the
PPS and optional RPS reside.
The alarm cabling is connected on the backplane of the even peripheral shelves as follows:
(P3 is located behind the PPS and RPS power supply slots, on the backplane of the
motherboard.)

When the Peripheral Shelf Unit does not include an odd shelf:
P6 on the PBD-ATS is connected to Pin 29 of P3 on the even shelf.

When the Peripheral Unit includes an odd shelf:

P6 on the PBD-ATS is connected to Pin 29 of P3 on the even shelf.

P7 on the PBD-ATS is connected to Pin 27 of P3 on the even shelf.

An FC1 cable is connected between pins 1-7, denoted To Lower MBS3, on P3
of the odd shelf to pins 19-25, denoted To Upper MBS3, on P3 of the even
shelf.
H-41 connector (2-wire) cables are used to connect between P6/P7 and P3. The three pin
connector can be attached to the upper 3 pins or lower 3 pins of P6/P7, so that if one of
the pins break, there is always an alternative wiring option.

The H-41 connector has polarity, so that the same light colored wire
connects from the bottom of both P6/P7 to the right-most pin 27 and 29
header on P3.

Figure 6-26 illustrates the location of RPS inter-shelf cable FC1 and PPS/RPS Alarm cable
H-41 with polarity. The FC1 carries the RPS control signals and outputs between the odd
and even peripheral shelves. The H-41 cable carries alarm signals to the PBD-ATS
servicing the Peripheral Unit which contains the PPS (and RPS).
The appearance of some flat cables may vary from the illustration, and the conductors
may exit from the right side of the connector instead of the left as shown. Note the position
of the white dot which appears on the connectors of most FC1 cable assemblies. If the
Cabinet Descriptions

white dots are not visible on the cable assembly, make certain that the color of the wire
conductor at the top edge of the cable is the same at both ends.

 10 Power Distribution
...................................................................................................

Each cabinet is equipped with a power distribution network consisting of bus bars and
wire conductors. Through this network, supply voltages are distributed throughout the
cabinet to the circuitry which require them.
Power enters the cabinet from a battery eliminator power supply, or from a power
distribution board; to the SGND, –48V IN, and 48V RTN IN power terminals located in
the power input cavity, in the upper right corner of the cabinet rear. See Ground and Power
Wiring beginning on page 2-11 for details.
The SGND terminal connects to the metallic frame of the cabinet. Note that the –48V IN,
or –48 volt supply is protected by a fuse located near the input terminal. The –48V IN, and
48V RTN IN are then routed from the power input cavity to two bus bars mounted along
the right rear of the cabinet.
The bus bar which runs closest to the backplane is the 48V RTN IN, or positive side of the
48 volt power supply. The bus bar running closer to the back of the cabinet is the –48V IN,
or negative side of the power supply.
The 48V RTN IN bus is the signal common, or ground for all internal supply voltages and
signals; as well as for telephony signaling purposes, including Ground-Start and E&M
trunks, and RS-232 serial data ports. The positive output of the power supply or power
distribution board must be connected to an approved earth ground for proper system
operation.
The SGND terminal also must be connected to an approved earth ground through a
separate path (separate wire).

 11 Configuration Options
...................................................................................................

This subsection describes the various factory set configuration options for the Coral
FlexiCom 6000 system up to a maximum of 16 peripheral shelves. Each Peripheral Shelf
Unit (even and odd shelf) receives 512 time slots, see Figure 6-18. The system is configured
with the least possible blocking.

Possible Cabinet Configurations

The different combinations of cabinet configurations are summarized in Tables 6-6 and
6-7. These table defines the cabinet structure, maximum ports and Time Slot definition for
each type of Coral cabinet code.

Each Coral FlexiCom 6000 system must include at least one main control
cabinet with either 3 or 4 shelves, where the bottom shelf is always the
control shelf. The system may also include a maximum of 4 Expansion
cabinets.

Cabinet Code Configurations

The Cabinet Code configuration is printed on the label inside of the Coral FlexiCom 6000
cabinet and can be decoded as follows:

 7.1 PPS
Peripheral DC Power Supply Unit

1 General Description
...................................................................................................

The Peripheral Power Supply (PPS) provides internal operating voltages for the
Coral FlexiCom 6000 peripheral shelves.
The PPS operates from a nominal input of 48 volts direct current (DC), typically supplied
by an external 48VDC rectifier or stationary battery plant. Actual input may vary from 42
to 58 volts; allowing operation from a battery power source while the batteries are charged
at an equalize charge rate and upon AC power failure, until the batteries are completely
discharged.
The PPS contains three, pulse width modulated (PWM), switch-mode DC-DC converters
which convert the 48VDC input power to +5VDC, –5VDC, +12VDC, and–12VDC
operating voltages for the Coral internal circuitry. The PPS also further filters and current
limits the 48VDC input to feed the peripheral card slots. All outputs except the –48VDC
output are regulated. Voltage and current level monitoring circuitry check each output of
the PPS and produce alarm signaling to the Coral system main processor in the event of
abnormality.
Each PPS is designed with the capacity to support two fully populated peripheral shelves
(one Peripheral Shelf Unit) with an average mix of port types. The outputs of the PPS are
designed to be paralleled with the outputs of a second PPS, offering load sharing of power
supplies. Coral FlexiCom 6000 cabinets are factory wired to support load sharing. In

PPS Peripheral DC Power Supply Unit

cabinets with only 2 peripheral shelves, the power supply slots of both peripheral shelves
are wired in parallel. In Main cabinets with 3 peripheral shelves, the lower two peripheral
shelves are wired in parallel, while the top peripheral shelf stands alone. In cabinets with
4 peripheral shelves, the lower two peripheral shelves are wired in parallel, and the upper
two peripheral shelves are wired in parallel, regardless of their even or odd numbering.
It is, however, possible to populate two peripheral shelves wired in parallel, in such a way
as to exceed the capacity of a single PPS. Station cards, in particular, place a heavier load
on the PPS than other card types. For such cases, a PPS must be installed in each shelf to
prevent overload of the PPS output; the two paralleled PPSs share the load of both
shelves, but do not provide redundancy. When required, or if one PPS is overloaded, up
to two PPSs can be installed in one peripheral shelf (when an RPS is not required for that
shelf).
7

Coral FlexiCom 6000 Installation Manual Power Supplies 7-1

 PPS for Coral AIR Wireless Systems
Each PPS card can support up to 4 (four) SKW/x cards, on the peripheral shelves it
feeds (either 1 or 2). If more SKW/x cards are required, they must be placed on other
peripheral shelves or additional PPSs must be added.

There is no limitation for SKK cards used in FlexAIR systems.

PPS Front Panel

Figure 7-1 illustrates the front panel of the PPS, which contains test points for measuring
all output voltages. In addition the +5VDC, –5VDC, and +12VDC regulators are voltage
adjustable via potentiometers. Two panel mounted fuses protect the PPS circuitry from
current overload. F1 protects the +5VDC, –5VDC, +12VDC, and –12VDC DC-DC
converters, while F2 protects the –48VDC filter circuitry, which feeds –48VDC to the
peripheral card slots. The green power indicator illuminates if input power is applied to
the DC-DC converters.
The power ON/OFF switch controls all voltage outputs from the PPS.

Switching one PPS to OFF does not remove power from the peripheral shelf if an
adjacent, paralleled PPS is switched ON. Paralleled power supplies must both be
turned off to remove all power from both shelves.

 2 Circuit Description
...................................................................................................

Figure 7-2 presents a block diagram of the PPS power supply. Three separate,
switch-mode, DC-DC converters convert the 48VDC input power to +5VDC, +12VDC,
and –5VDC and –12VDC outputs. One DC-DC converter provides both the –5VDC and
–12VDC outputs.
Filtering circuitry minimizes ripple and noise on the –48VDC feed to the peripheral cards.
The filtering circuitry typically produces an output voltage about 1.5 volts lower than the
input to the PPS.
Monitoring circuitry verifies that each voltage output is within tolerance. Should any
voltage fall out of tolerance, the monitoring circuitry produces an alarm signal to the
system processor, and shuts the PPS down. The green power indicator of a PPS in shut
down condition is still illuminated.
Following a shutdown, and when there is no clear reason for the voltage to drop out of
tolerance, the power ON/OFF switch must be turned to OFF and then to ON in order to
return the power supply to working order.

Turn on the PPS only after powering a Control Shelf PS-ATS, otherwise the shelves may
not initialize.

 3 Adjustment
...................................................................................................

Three of the five voltage outputs of the PPS are adjustable from front panel mounted
potentiometers. Table 7-1 lists the nominal output, adjust to, and minimum and maximum
output voltage limits of the PPS. Each output must fall within the minimum and
maximum voltage range. Voltages outside of this range may cause irreparable damage to
the PPS or other circuitry in the system.
Adjustment of the PPS outputs on systems which are cut over and processing calls should
be conducted after hours or during periods of minimal, non-critical traffic; if at all
possible. Voltage fluctuations may cause unstable operation of the system or cause the
PPS monitoring circuitry to shut the PPS down.
To adjust the PPS voltage outputs, first measure each voltage using a high impedance DC
voltmeter, set to the 20 volt or next higher scale (use the 200 volt scale when measuring
the –48VDC output.) Always measure from the voltage (i.e. +5VDC, +12VDC, or –5VDC)
test jack to the corresponding return test point. Using the incorrect return test jack may
cause erroneous measurements.
Note the initial voltage measured. Gently insert a small, straight blade screwdriver into
the adjustment hole for the appropriate voltage, in the front panel of the PPS. Rotate the
screwdriver slightly, using gentle, even pressure. Watch the voltmeter to determine the
effect. Then adjust the output voltage to match the figure in the right hand column of Table
7-1. Repeat this procedure for each output.
The –12VDC and –48VDC outputs of the PPS cannot be adjusted. Neither voltage is
critical for proper system operation. Verify that the two voltages fall within the minimum
and maximum voltage range listed in Table 7-1.

The PPS output voltages are calibrated prior to shipment. Because of the
difficulty in measuring output voltages under proper conditions, it is strongly

PPS Peripheral DC Power Supply Unit

recommended that the PPS voltage levels be adjusted by a qualified service
facility, and not in the field.

 4 Installation
...................................................................................................

The PPS power supply is inserted in the left-most slot of the card cage. A second PPS can
be installed in the RPS slot, when an RPS is not required.
The PPS can be installed in slots labeled either for the PPS or RPS. Up to two PPSs can be
installed in one Peripheral shelf.

To Install the Power Supply

1. Ensure that the PPS power switch is in the OFF position.
2. Position the two guide ridges, located on the left panel of the power supply at top
and bottom, into the card edge guides corresponding to the PPS slot (labeled on
the card cage).
3. Slide the PPS gently but firmly, until fully inserted into the card cage. Verify that
the positioning pins, located on the front edge at top and bottom of the card cage,
pass through companion positioning holes on the card front panel. A slight
resistance should be felt as the multi-pin connectors engage at the rear of the
power supply and backplane.
4. Do not force the supply into the card cage. Irreparable damage may occur if the
multi-pin connectors mis-align while attempting to insert the power supply into
the card cage. If more than slight resistance is encountered, partially slide out the
card from the cage and verify the alignment of the guide ridges with the card
edge guides. If alignment appears to be correct, remove the card from the slot and
inspect the multi-pin connectors for bent pins and debris in the pin holes.
5. Turn the PPS power switch to the ON position.
PPS Peripheral DC Power Supply Unit

Turn on the PPS and RPS units only after powering the Control Shelf and verifying that
the Control Shelf has initialized properly, otherwise the cards in the peripheral shelves
may not initialize.

 5 Troubleshooting
...................................................................................................

Power supply failure generally results in the loss of one or more output voltages.
However, protection circuitry in the power supply regulator circuitry may shut down a
regulator due to a current overload caused by an external fault.
Measure all voltage outputs from the power supply to determine that they are within
acceptable limits. If any voltage except the –48VDC is too high, the PPS should be
replaced. If one or more voltage is too low, continue the troubleshooting procedure
described below.

Troubleshooting procedure
1. Each PPS can support two fully populated peripheral shelves. The outputs of the
PPS are designed to be paralleled with the outputs of a second PPS. In cabinets
with 2 peripheral shelves, the power supply slots of both peripheral shelves are
wired in parallel. In cabinets with 3 peripheral shelves, the lower two peripheral
shelves are wired in parallel, while the top peripheral shelf stands alone. In
cabinets with 4 peripheral shelves, the lower two peripheral shelves are wired in
parallel, and the upper two peripheral shelves are wired in parallel.
2. Turn the PPS power switch off, remove all Peripheral and Shared Service cards
from the (one or two) relevant peripheral shelves. Then power-up the PPS and
measure the voltage outputs once again. If the voltages return to acceptable levels,
the problem is caused by one of the cards that were removed.
3. To determine which card is causing the problem, insert the Shared Service and
Peripheral cards into their appropriate slots, one at a time. Measure the affected
voltage each time a card is inserted. If the voltage drops after a particular card is
inserted, that card is faulty, and should be replaced.

 7.2 RPS
Ring Generator Power Supply Unit

1 General Description
...................................................................................................

The Ringer Power Supply (RPS) provides high voltage ring generator current required by
single-line telephone station ports of the 8SLS, 16SLS, 24SLS, 4SH/S, 8SH/S, 16SH/S,
4SH/S-LL, 8SH/S-LL, 16SH/S-LL or 8SM cards.
The RPS operates from a nominal input of 48 volts direct current (DC), typically supplied
by an external 48VDC rectifier or stationary battery plant. Actual input may vary from 42
to 58 volts: allowing operation from a battery power source while the batteries are charged
at an equalize charge rate; and under power failure, until the batteries are completely
discharged.
The RPS contains a low frequency oscillator and power amplifier which convert the
48VDC input power to 75, 85, or 105 volts (16, 20 or 25Hz) alternating current (AC); for
use as a ringing and message waiting signal on industry standard, single-line telephones
(SLTs); and magneto telephone station ports. The output voltage is selected by choosing a
tap on the output transformer. The output voltage is regulated and adjustable from the
front panel. Voltage monitoring circuitry checks the output of the RPS and produces alarm
signaling to the Coral system main processor in the event of abnormality.
Each RPS is designed with the capacity to support two fully populated peripheral shelves
with average mix of port types. If extra capacity is required, an RPS may be installed in

RPS Ring Generator Power Supply Unit

each peripheral shelf. The RPS employs automatic switching circuitry to share the output
between two peripheral shelves. When two RPSs are installed in peripheral shelves wired
for shared RPS operation, an operating RPS in either peripheral shelf supplies both
shelves. If both RPSs are operational, each RPS supplies energy only to the shelf in which
it is installed.
Coral FlexiCom 6000 cabinets are factory wired (via the FC1 cable) to support sharing and
redundancy. In main and expansion cabinets with 2 peripheral shelves, the power supply
slots of both peripheral shelves are wired for shared RPS operation. In main cabinets with
3 peripheral shelves, the lower two peripheral shelves are wired for shared RPS operation,
while the top peripheral shelf stands alone. In expansion cabinets with 4 peripheral
shelves, the first and second peripheral shelves are wired together for a shared RPS; and
the third and fourth peripheral shelves are wired together for a shared RPS operation.

The front panel of the RPS contains test points for measuring the voltage output. The
output is voltage adjustable via a potentiometer, and frequency select via a sliding switch.
Two panel mounted fuses protect the RPS circuitry from current overload. F1 protects the

oscillator and power amplifier circuitry, while F2 limits the BRV output current
superimposed on –48VDC to the peripheral card slots. The green power indicator
illuminates if input power is applied to the oscillator and power amplifier.
The power ON/OFF switch controls the voltage output from the RPS.

Switching one RPS to OFF does not remove power from the peripheral shelf if a shared
RPS is switched ON. Shared power supplies must both be turned off to remove all
power from both shelves.

Coral FlexiCom 6000 Installation Manual Power Supplies 7-11

 2 Circuit Description
...................................................................................................

Figure 7-5 presents a block diagram of the RPS power supply. The low frequency oscillator
produces an AC waveform which is frequency-selectable via the front panel mounted
selector switch. The frequency selection options are 16Hz, 20Hz and 25Hz. The output of
the oscillator is fed to the power amplifier. A front panel mounted voltage adjust
potentiometer varies the gain of the amplifier, increasing or decreasing the output voltage.
The output of the power amplifier is fed to the output transformer. The output
transformer has three taps to select the nominal output voltage.
The monitoring circuit verifies that the RPS is producing ring voltage. If the monitoring
circuit is satisfied; relay K1 is operated, passing the RPS output to BRV OUT, the BRV bus
of the first peripheral shelf.
The RPS output also is passed through the released contacts of relay K2 to BRV IN, which
is connected to the BRV bus of an adjacent peripheral shelf. If an RPS also is installed in
the adjacent shelf, relay K2 is operated. However, the BRV bus of both shelves are still
bridged together through the contacts of relay K1 in the second RPS. If both RPSs are
functioning properly, relays K1 and K2 of both RPSs are operated, separating the
peripheral shelf BRV busses and passing the RPS outputs only to their respective
peripheral shelves.

The RPS is inserted in the left-most slot of the card cage.

To Install the RPS

1. Ensure that the RPS power switch is turned OFF.
2. Verify that the output voltage selection tap is set to 75VAC (as required by UL
rules), see Figure 7-4.
3. Position the two guide ridges, on the right panel of the power supply at top and
bottom, into the card edge guides corresponding to the RPS label above the card

peripheral cards are inserted in any peripheral card slot fed by the RPS during the
adjustment process. Each RPS slot in a peripheral even shelf may be wired to supply ring
voltage to the adjacent odd peripheral shelf. See RPS/PPS Alarm Cabling beginning on page
6-36.
Insert the RPS into the RPS card slot (far left) and place the RPS power switch in the ON
position. Measure the AC voltage across the test points TP1 and TP2 using a high
impedance, AC voltmeter; set for the 200 volt or next higher scale. Adjust the output
voltage using the front panel potentiometer. With no load, adjust the output voltage to
read within 5 volts of the selected output transformer tap voltage. Table 7-2 lists the
acceptable output voltage range of the RPS for each of the three output voltage selection
taps. Never adjust the output voltage between 90VAC and 100VAC, or greater than
110VAC.

The maximum number of single line telephones which can be fed ring generator
simultaneously from each RPS is 20, by default, and can be determined by the System
Features parameter MAX_RING (Route: SFE,2) in the system database. See the Program
Interface Reference Manual for details.
One RPS can be installed per shelf. A single RPS can supply power to several SLT ringers
located on different shelves. When SLTs are installed in shelves without an RPS, the SLTs
can be powered by an RPS installed in another shelf, this is accomplished through a
definition in the RINGER# parameter (Route: RPS), in the system database.

Dual Control DC Power Supply Units

1 General Description
...................................................................................................

The PS-ATS power supply unit provides internal operating voltages for the Coral
FlexiCom 6000 control shelf.
The PS-ATS operates from a nominal input of -48VDC, typically supplied by an external
48VDC rectifier or stationary battery plant. Actual input may vary from -40 to -60 VDC
allowing operation:

from a battery power source while the batteries are charged at an equalize charge
rate

under power failure, until the batteries are completely discharged.

PS-ATS Front Panel

Figure 7-6 illustrates the front panel of the PS-ATS unit.
Two LED indicators are located on the front panel:

Power (Green) — Lights when power is supplied to the system
Fail (Red) — Lights when the PS-ATS is faulty

PS-ATS Dual Control DC Power Supply Units

The Fail (red) LED lights up when one of the voltage outputs (+5V, +3.3V, +12V,
-12V) exceeds its specified range.

Four mounting screws (two at the top and two at the bottom) and a handle enable
the insertion and extraction of the PS-ATS into its card slot. 7

...................................................................................................

Figure 7-7 presents a block diagram of the PS-ATS power supply circuits and voltage
inputs and outputs.
The PS-ATS includes two separate switch mode, DC-DC converters that convert the
-48VDC input power to the +5V and +3.3V outputs. Another switch mode, DC-DC
converter, along with two regulators provide the +12V and -12V output.
Filtering circuitry minimizes ripple and noise on the -48 VDC feed to the Control cards.
The PS-ATS also contains Hot Swap circuitry for redundancy purposes.
The Control and Alarm (monitoring) circuitry verifies that each voltage output (with the
exception of the -48VDC output) is within specification. Should an output voltage deviate
from specification, the monitoring circuitry produces an alarm signal to the system
processor (displayed on the PI terminal), causing the red Fail indicator to illuminate.
Additionally, the green Power indicator remains illuminated when power is supplied to
the system.
If the Voltage input drops below -40VDC, then the PS-ATS shuts down.

 3 PS-ATS Orientation and Installation
...................................................................................................

The system may include up to three PS-ATS units for redundancy.

The Hot Standby system is designed to allow hot insertion and hot swaps of a PS-ATS unit,
such that, if one of the PS-ATS units malfunctions, system operation — call processing and
maintenance is not interrupted because the second unit alone can continue to power the
Control Shelf.
A PS-ATS unit is installed on the right side of the Control Shelf (two slots, PS2 and PS3 are
provided for the units on the right side, see Figure 6-6) in an upright position.
The PS-ATS unit on the left side is installed upside down in slot PS1.

Installing the Power Supply Units

Two Power Supply Units are normally shipped in the Common Control Shelf of the
system already fastened into place. Verify that the two power supplies are installed in
slots PS2 and PS1 on the bottom corners of the Control shelf. There is an empty third
power supply slot in the upper right hand corner (slot PS3). This slot is for future Coral
Configurations.
1. To insert the PS-ATS unit(s), grasp its handle with one hand.
2. Verify that the power supply is oriented correctly:

When installing the PS-ATS in either slot on the right side, in slots PS2 and PS3,
ensure that the Fail and Power LEDs are located at the top of the unit, see
Figure 7-8 for correct card orientation.

When installing the PS-ATS on the left side of the control shelf, in slot PS-1,
PS-ATS Dual Control DC Power Supply Units

ensure that the Fail and Power LEDs are at the bottom of the unit (i.e. install
the unit upside down), see Figure 7-9 for correct card orientation.
3. Align the unit with the card slot guides and forcibly push the power supply
straight into the card slot. Resistance is felt as the multi-pin connectors on the
power supply meet the mating connectors on the backplane and engage.
4. Force the PS-ATS completely into its slot until the front panel of the power supply
is flush with the front frame of the card cage. If more than considerable resistance
is encountered, remove the power supply and examine the connectors for bent
pins or interfering debris.

Irreparable damage may occur if the multi-pin connectors are misaligned

during unit installation.

captive mounting screws on each corner of the unit.
6. After Power is supplied to the system, verify that the green Power indicator
illuminates.

 4 Troubleshooting
...................................................................................................

Power supply failure generally results in the loss of one or more output voltages.
However, protection circuitry in the power supply regulator circuitry may shut down a
regulator because of a current overload caused by an external fault.
The red Fail indicator on the front panel of the PS-ATS illuminates when any of the output
voltages are outside of specification. This may be caused by internal or external faults, the
technician must isolate the problem and replace the faulty PS-ATS when necessary.
In a Hot Standby system, if one PS-ATS is faulty, while the second PS-ATS is functioning
properly, then the “red lit” PS-ATS is obviously at fault and should be replaced.
If both PS-ATS units have the red Fail indicator illuminated, then the Coral system is not
functioning properly and the problem must be isolated to either both the PS-ATS units or
one of the Control Cards or the backplane unit.
Following the shutdown of a PS-ATS unit, the fuse should be changed. If this does not
restore the unit, then the PS-ATS unit should be replaced.

Determining the Cause of the Fail Indicator

The red Fail indicator can be activated by malfunctions in the PS-ATS, the Control Shelf
cards or the backplane.
1. Turn off the Main Power to the Coral System.
2. Turn off all the PPS and RPS units in each Coral cabinet.
3. Extract each control card from the control shelf so that it protrudes at least by one
inch (2.5 cm).

PS-ATS Dual Control DC Power Supply Units

4. Unscrew the 4 screws on the front panel of each PS-ATS unit.
5. Forcibly pull out the PS-ATS units from their slots so that they also protrude from
the card cage.
6. Turn on the Main Power to the Coral System.
7. Insert only one PS-ATS unit.

If the red FAIL indicator lights, then this PS-ATS is faulty and should be
replaced. Repeat this procedure for the other PS-ATS unit.

If the green Power indicator lights and but the red FAIL indicator does not
light, then the PS-ATS is functioning properly. Continue with the next step.
8. Begin checking the other units and determine the faulty unit by process of
elimination. Continue with the next step.
7

Coral FlexiCom 6000 Installation Manual Power Supplies 7-23

 9. Begin checking all the Control Cards on one side, one at a time, and then the
Control Cards on the other side by inserting the cards one by one beginning from
the middle of the Control Shelf with each side. Ensure that the card’s rear panel
connectors engage properly with the backplane and that they initialize properly.

If one of these cards is faulty, it must be replaced.

If all the Control Cards are functioning properly, continue with the next step.
10. If all the Control cards and PS-ATS units are functioning properly, then the
Control Shelf backplane and MPG-ATS unit must be checked for faults and
replaced if needed.
11. After the faulty unit has been located and replaced, and after returning power to
the Coral, thus powering the PS-ATS unit(s), turn on all the PPS and RPS units in
each Coral cabinet.

PS-ATS Fuses
The PS-ATS units are wired in series with fuses located on the front panel (top left-hand
corner) of the Control Shelf (PS1, PS2, & PS3), see Figure 6-6. Each of these fuses is wired
in series with the labeled PS-ATS unit. Additionally, each PS-ATS unit, includes a 10 Amp
S.B. fuse, F1, (see Figure 7-12) within the PS-ATS unit.
Additionally, a Power Input Fuse (30A/F 60VDC) is located in the Power Input Cavity, (in
the rear of the main cabinet at the top left-hand corner, see Figure 2-4) protecting the
circuitry in the entire cabinet.
Refer to Figure 7-10 and Figure 7-11 for a DC wiring diagram of the Power Cabling and
Fuse series.

Locating the Blown Fuse

In case any one of these fuses blows (except for the Power Input Fuse), a system alarm is
immediately displayed on the PI screen indicating which PS-ATS unit has failed (PS1, PS2
or PS3). The technician must determine which of the two PS1, 2, or 3 fuses has blown. The
fuses located on the front panel of the Control Shelf have a red indicator which can be
PS-ATS Dual Control DC Power Supply Units

clearly viewed at the top of the fuse case once it has blown. If none of those fuses has a red
tip, then the F1 fuse inside the indicated PS1, 2, or 3 has blown and must be changed.

Replacing the PS1, PS2 or PS3 Slot Fuses

The PS1, PS2 and PS3 Front Panel fuses have a spare fuse located on the left side of the
Control Shelf.
1. Remove the PS-ATS from its card slot.
2. Remove the clear plastic fuse case.
3. Forcibly remove the blown PS-n fuse by pulling it directly outwards.
4. Replace the burnt fuse with the fuse located on the left side of the Control Shelf.

Replacing the PS-ATS F1 Fuse

1. Unscrew the mounting screws at the top and bottom of the faulty PS-ATS.
2. Remove the PS-ATS by gripping the handle and pulling with slight force.

General Description

1 General Information
...................................................................................................

The Coral FlexiCom 6000 system provides a Hot Standby Dual Control System which
offers a significant measure of system reliability and protection by assuring non-stop
operations despite the possible failure of any control component. The redundant Coral
FlexiCom 6000R includes two complete sets of control hardware, each able to perform the
control operations of the entire system. Independently, the two sets function
interchangeably making it possible for either set to take over control functions
automatically in the event of malfunction to any portion of the control system. Similarly,
the readily available second control system facilitates maintenance needs so that when
periodic routine maintenance procedures are carried out, there is no interference to the
continuity of the system operations.
The Common Control portion of the Coral system provides the control mechanism for
establishing audio and data connections or calls via the PCM bus between Peripheral I/O
ports in the system.
Common Control is divided into five different functions:

Main Processor

Generic Feature Memory

Common Control Shelf General Description

Database Memory

Mirrored Memory and Switching Matrix

Peripheral Bus Interface or Group Controller
Each standard Coral Common Control card set includes an MCP-ATS Main Processor, a
32GC card, and an SAU unit. FlexiCom 6000 systems may also include dual CLA-ATS
card(s) and/or 4/8XMM expanded memory card(s) which are provided in separate
packaging and require installation in the control shelf.
The MCP-ATS card is the main control processor of the system. The 32GC card serves as
a communication link in the system, between the control cards and the PB-ATS cards
located in peripheral shelves. The 32GC card contains the clock circuitry to synchronize
the peripheral section of the system, digital tone generators (dial, busy, ringing, ringback,
DTMF, MFC, and test), High-Level Data Link Control (HDLC) bus interface circuitry, and
8

Pulse Code Modulation (PCM) bus interface circuitry.

Coral FlexiCom 6000 Installation Manual Common Control Cards 8-1

 The optional CLA-ATS card incorporates the applications processor and Ethernet
interface circuitry for the FlexCT CoraLINK computer-telephony integration (CTI) link.
The MCP-ATS, CLA-ATS, and 32GC card reside in designated card slots in the card cage.
The 4/8XMM card is a daughter card that is mounted on the 32GC card to increase the
Coral database when needed. The 4/8XMM is also a required shared memory card for the
CLA-ATS card.
The card slot designation appears below each common control card slot on the front of the
card cage.
An SAU device is attached to the SAU port on the front panel of each 32GC card.

Common Control Shelf

The Common Control Shelf is positioned at the bottom of the main control cabinet. It is
built to provide two sets of slots for the components required for the redundant control
sides of a Coral FlexiCom 6000R Hot Standby (HSB) system. The corresponding slots
appear on the left and right sides beginning from the middle outwards, for each set of
control system cards. A single motherboard, the MBC-ATS, behind which the MPG-ATS
resides, serves as the backplane for both sets of control systems.

 2 Control Shelf Backplane Connections
...................................................................................................

The MPG-ATS card is the main cable connection card attached to the center of the rear
backplane of the control shelf. Two sets of cables are attached from the MPG-ATS card to
each of the even numbered peripheral shelves.
Figure 8-1 shows the rear backplane of the Control Shelf where the MPG-ATS card is
installed in the center. The MPG-ATS card is factory installed.

Replacing an MPG-ATS
The MPG-ATS card is designed for durable and long term use. However, if the need to
replace one arises, follow these directions:

The MPG-ATS card can only be replaced on a system which is shut down.

1. Remove all PB-ATS cable and ground connections.

2. Unfasten the 14 mounting screws (4 on each side of the MPG-ATS, 3 on the top
and 3 on the bottom).
3. Unfasten the two Hex socket screws on the middle of the MPG-ATS card.
4. Grasp both knobs and unfasten them simultaneously by turning them
counter-clockwise.
5. Pull on the knobs. The MPG-ATS card pulls off.
6. Grasp the knobs of the replacement MPG-ATS card, align the connectors with
their complements on the Control Shelf backplane, noting the UP indication for
the top of the MPG-ATS card.

4 Card Handling Procedures

...................................................................................................

Each of the Common Control cards contain circuitry, which is sensitive to

electrostatic discharge (ESD). Failure to observe safe handling procedures
for static sensitive circuitry may result in permanent damage to a card.

The system cabinet is equipped with an anti-static wrist strap attached to the
top above the card cage. This wrist strap should be worn while inserting

Common Control Shelf General Description

removing or handling any card in the system.

Slot Coded Keys

Each Control Shelf slot is equipped with physical coded keys, a mechanical feature,
designed to compel correct card placement and to prevent the possibility of placing any
circuit card in the wrong position. Three coded keys are placed at the front of each slot.
Corresponding matching coded keys are placed the top and bottom of each control card.
The physical coded keys on the Control cards are positioned such that when the card is
inserted, the shelf and card coded keys must match for the card to insert fully into the slot.
The coded keys prevent inserting the wrong card into a slot. Figure 8-4 illustrates the
control shelf slot’s coded keys.

Control card is placed in an incorrect slot with power applied.

8-8 Common Control Cards Coral FlexiCom 6000 Installation Manual

 5 Fan Tray
...................................................................................................

The Fan tray is located at the bottom of the Control Shelf and provides the cooling system
for the components located in the Control Shelf. The Fan Tray contains three fans, each
fuse protected. The fans force air through a filter to cool the control cards and power
supply units.
The size of each fan is 120x120x80mm and supplies a minimum of 77 CFM at the rated
voltage. The fans operate from the main -48V power supply.
On the back of the fan tray is a connector through which the power and signaling are
connected.
Each fan has a fuse providing electric fault protection. Should a fan malfunction, an alarm
message is immediately displayed on the PI terminal: FAN FAULT. The faulty fan
component should be changed as soon as possible.
The technician must determine the faulty component, either one of the fuses has blown
and must be replaced, or one of the fans is not functioning. The fan tray should be replaced
only when the main power to the system is turned off.
The alarm signals from the fan to the 32GC card are isolated from the 48V power source
by an opto-coupler device.

Determining the Fan Fault and Replacing the Fan Fuses

When a FAN FAULT alarm has been sent to the PI terminal, the technician must check the
fan tray and isolate the problem to either a faulty fuse or one of the fans.
1. Remove the Fan Tray fuses one at a time to locate the blown fuse by twisting the
fuse counter-clockwise and removing.
2. Inspect the fuse. If it is blown, replace with new fuse, by reinserting a new

Common Control Shelf General Description

0.5Amp/250V fuse.
3. Twist back into place.
4. If none of the fuses are blown then one of the fans is not functioning (this may be
obvious by simple inspection) and continue with Replacing the Fan Tray, below.
Otherwise, the FAN FAULT repair terminates with the repaired fuse.
8

Coral FlexiCom 6000 Installation Manual Common Control Cards 8-9

 Replacing the Fan Tray
1. Turn the Main System Power off.

Main Power should only be turned off when call traffic is lowest to avoid
interrupting an operative Coral system.

1. Unscrew the screws holding the fan tray to the control shelf chassis, see Figure 8-5.
2. Firmly pull out the fan tray.
3. Insert the new fan tray and gently push it back completely into its slots so as to
assure the backplane connections are secure.
4. Fasten the screws, attaching the fan tray to the chassis.
5. Return Power to the system and check that all the fans are functioning properly.

 8.2 MCP-ATS
Main Processor Card

1 General Description
...................................................................................................

The MCP-ATS is the main control processor for the Coral FlexiCom 6000 system. The
MCP-ATS card integrates the Main Processor, memory management circuitry, local bus
interface, programming and maintenance data port, real-time clock and generic feature
software memory. This card also supervises overall system operation by executing
system-wide processes. These processes include port connection management, feature
management, generic feature software installation, configuration database management,
Program Interface input/output, and diagnostic testing.
The MCP-ATS card contains the main control processor circuitry and Memory
Management circuitry and utilizes a powerful Pentium microprocessor with PC
architecture, which connects to the backplane with Compact PCI.
The front panel of the MCP-ATS card includes diagnostic indicators, and a
communication serial COM (PC port) for programming and maintenance interface. The
main processor receives status messages from the system ports and determines the
appropriate response based on programming entries contained in the system database.
The MCP-ATS is a “hot insertion” card which allows the technician to remove the card
from its powered up slot while the MCP-ATS from the other side takes control.

Program Interface Connection

The Program Interface (PI) provides a menu driven program facility for viewing and MCP-ATS Main Processor Card
updating the Coral system database, and for performing and monitoring diagnostic
routines, from a simple data terminal or personal computer. The PI terminal is connected
to the COM1 (9 pin RS-232 connector) data terminal port provided on the MCP-ATS front
panel, otherwise known as the KB0 connection. Table 8-1 describes the KB0 RS-232 pin
connections to the PI terminal.
Hot Standby systems require each MCP-ATS to be connected to its own PI Device, where
one is always Active, while the other is in Standby mode, see Program Interface Device
Connection beginning on page 2-41 for further PI connection details.

 3 Compact Flash Memory Disk
...................................................................................................

An ATA-type PCMCIA connector houses the Compact Flash Disk (CFD) memory. The
CFD contains the generic feature software and database backup files.
The CFD disk has an erasable memory capacity of 16-64MB. The appropriate memory
capacity is dependent on the Coral system configuration.
The ATA type PCMCIA slot is housed on the MCP-ATS card side edge.The MCP-ATS card
must be removed from the Control Shelf slot to access the ATA type PCMCIA slot causing
the system to shut down while the CFD is replaced. Both MCP-ATSs required the same
version CFD, therefore, if one is updated the other must be updated at the same time, see
Upgrading the Coral Generic Version on page 4-2.

Inserting the CFD

The CFD card edge is contoured such that it may only be inserted either face down or face
up (depending on the MCP-ATS CFD connector/drive).

CFD Label Description

The CFD label describes the CFD contents, its Catalog number, the loaded Software
version, and the SAU number that must correspond to the SAU device attached on the
front panel of the 32GC on the same side of the MCP-ATS, see also Software Authorization Unit
(SAU) on page 8-50.

 6 Card Installation
...................................................................................................

The MCP-ATS card(s) are shipped to the customer already installed in the Control Shelf
slot(s). If for any reason a card must be removed and replaced (such as when performing
an upgrade and the card(s) must be removed in order to insert the new CFD) the
MCP-ATS card installation procedure is described below.

All circuit cards are sensitive to electrostatic discharge (ESD) and can easily be
damaged. Use an antistatic wrist strap when handling the card.

Installing/Removing the MCP-ATS

This procedure describes the card installation. To remove the card, reverse the steps,
beginning from the last step.
1. Grasp the card by the injector/ejector levers located at the top and bottom of the
card front panel.
2. Locate the correct MCP-ATS card slot and orient the card for its card slot
accordingly:

If this card is to be inserted on the right side of the control shelf, insert the card
right side up (all the printing on the card front panel is upright). See
Figures 8-9, 8-10 and 8-11 to view upright cards.

If the card is to be inserted on the left side of the control shelf, insert the card
upside down (all the printing on the card front panel is upside down).
3. Align the card top and bottom edge on the slot guide and gently slide the card
into the slot until resistance is met. The connecting pins on the backplane should
engage with the card’s connecting pins.
MCP-ATS Main Processor Card
4. Simultaneously push the injector levers inwards.
5. Verify that the card is flush with the card cage.
6. Fasten any screws that are required to secure the card (behind the levers).

Group Controller Card

1 General Description
...................................................................................................

The 32GC card serves as the communication link in the Coral FlexiCom 6000 system,
between the MCP-ATS and the PB-ATS cards located in peripheral shelves via the
MPG-ATS located at the motherboard rear backplane. Each of the redundant 32GC cards
interfaces with the same MPG-ATS which controls the bus signalling to the PB-ATSs,
see Figure 8-12.

MCP-ATS 32GC

Common Control Peripheral Units

The 32GC card contains the High-Level Data Link Control (HDLC) bus interface circuitry,
Pulse Code Modulation (PCM) bus interface circuitry, clock circuitry to synchronize the
32GC Group Controller Card

peripheral section of the system, and digital tone generators (dial, busy, ringing, ringback,
DTMF, MFC, and test). Additionally, the 32GC card contains circuitry to synchronize the
Coral peripheral clock to an external clock derived from a digital trunk interface. The
32GC card supports eight HDLC highways and thirty-two PCM streams, and up to
sixteen peripheral shelves. It is capable of establishing a maximum of 2000 calls between
ports on its maximum peripheral shelf capacity. This matrix allows for a constant frame
delay operation mode.
The 32GC card also houses the proprietary Mirrored Memory and Switching Matrix
essential for the Hot Standby control system. With this technology, the Standby control
8

system set snoops relevant information from the Active control system set. With this

Coral FlexiCom 6000 Installation Manual Common Control Cards 8-41

 information it readies its control card set for takeover of the control functions at any time
it may become necessary.
The voice port for peripheral cards is supported only from the Active 32GC card.
The base memory of the 32GC card contains a 2Mbyte memory in which the system
database is housed. The memory is SRAM and is protected by 3V battery backup, so that
data is saved and maintained during power loss.
The Expanded Memory Module, 4XMM or 8XMM, daughter card, is installed on the side
of the 32GC for large or complex Coral systems. It is also a required shared memory card
for the optional CLA-ATS. See 4/8XMM beginning on page 8-55 for further details on the
XMM card.

32GC Front Panel

The 32GC front panel includes diagnostic indicators, an SAU interface and a CLA Reset
button as shown in Figure 8-13. The items are described below.

Main - Red - lights during card initialization, is not lit when card is functioning
properly. If this indicator is lit, the 32GC is faulty.

A - Flashing Green - lights when this system side is in Active mode, the flashing is
slower when the system is most active.

S - Green - lights when this system side in Standby mode

M - Red - lights when this system side is in Maintenance mode

The following 3 items are duplicated, one on the left and one on the right, and emanate
from the lower (left items) and upper (right items) XMM cards when mounted on the
32GC (i.e. the LEDs and push button are physically located on the XMM card. The 32GC
only provides an opening on its front panel for displaying them).

The upper XMM is not used in this Coral Version. Therefore, the items on the
right side, appear as empty holes on the 32GC front panel.

 32GC Side Panel
The 32GC side panel, shown in Figure 8-14, includes a 100 pin connector and three
mounting holes, A, B and C, which aid in the piggyback installation of the XMM card.
A Lithium battery resides on the side panel as well. The battery insulator must be
removed before card installation.

2 Lithium Battery Handling Procedures

...................................................................................................

Removing and Replacing a Battery

To replace the lithium battery:
1. Remove the battery from its holder.
2. Insert the new battery into the battery holder.
Ensure that the side with the + symbol appears on top. Inserting the battery
upside down, while the battery fits in its holder, no hard connection is made.
Should the battery be placed in its holder with the + symbol on the bottom, no
hard contact is made, thereby disabling the battery.

There is the danger of explosion if the battery is replaced incorrectly. Replace the
battery only with the same or equivalent type recommended by the manufacturer.
Dispose of used batteries according to the manufacturer’s instructions.

Battery Condition Testing

A new lithium battery has sufficient energy to maintain power to memory circuitry and
real-time clock for approximately 90 days. The battery is not recharged however, when
system power returns. Therefore, if the battery has powered the memory and real-time 32GC Group Controller Card
clock for an extended period and near depletion, replace the battery. For single control
systems, the database contents should be backed up before the battery is replaced.
The battery voltage, tested under load, can be used to determine its state of charge.
Voltage measured across a new battery connected to the memory circuitry should fall
between 3.30 and 3.35 volts. If the voltage measured across a battery is less than 2.5 volts,
the battery should be replaced.
When a battery is low, an alarm message appears on the PI terminal, see Card Battery
Condition Test on page 3-16 for alarm messages.

 3 Time Slot Configuration
...................................................................................................

The 32GC card supports up to eight HDLC highways and 64 PCM streams, and up to 8
peripheral shelf units (see Figure 8-15).
Each PCM stream includes 128 Time Slots. Each shelf unit (even and odd numbered
peripheral shelf pairs) receives 512 Time Slots, divided into four groups of 128 Time Slots
(see Figure 8-16).
Each PB-ATS supports 128 or 512 PCM time slots, depending on the Peripheral Shelf Unit
backplane type. See PBD-ATS beginning on page 8-87 for more information. The 32GC card
automatically identifies whether the Peripheral Shelves units require only 128 of the entire
512 time slots or the entire 512 time slots per Unit.

 4 Circuit Description
...................................................................................................

Clock Selection
The external clock synchronization selector monitors the 4 inputs (two are in current use
while two more may be added in future configurations) for the presence of an 8.0 kHz
clock signal which may be derived from a digital trunk card. A primary and secondary
clock source may be defined in the system database, to synchronize the PCM clock of the
32GC card to the digital trunk. In the absence of an external clock source, the 32GC card
always reverts to an internal clock. Clock failure is reported in the Program Interface.

Digital Tone Generator

The digital tone generator generates the audio call progress tones used to notify the caller
of the status of the call. The stored tone patterns are output directly to the digital PCM bus
when required.
The system automatically verifies, upon system initialization, that the tones are
appropriate for the system as configured and overwrites the flash tone device on the GC
card as appropriate.

PCM Streaming
Each PCM stream operates at a data rate of 8.192 Mbps. Each PCM stream consists of
transmit and receive signals, each of which are divided into 128 time slots. Each time slot
is eight bits wide, sampled every 125 µs, or 8,000 times per second. This rate matches both
A/µ law PCM voice transmission rates to facilitate complete digital integration with the
local telephone network.
The time switching matrix, acting on command by the system processor, is responsible for
forwarding PCM voice samples from an incoming transmit time slot assigned to one port
to a complementary outgoing receive time slot for the recipient port.
32GC Group Controller Card

Using Time Slots

A call between two ports requires one transmit and one receive time slot on a single
peripheral highway. Therefore, the 32GC card is capable of establishing calls between any
2K ports and any other 2K ports, on any of the 16 peripheral shelves, for a maximum of
2K calls. This switching matrix allows for a Constant Frame Delay operation mode.

...................................................................................................

The Software Authorization Unit (SAU) is a small, encapsulated device that plugs into its
SAU port on the 32GC front panel, see Figure 8-17. As for all Coral systems, each 32GC on
the FlexiCom 6000R Control Shelf must have its own unique SAU installed.

The SAU enables a set of permissions and feature authorizations associated with its
unique identification number. The Coral software detects and verifies the permission
settings of the SAU on the Control card (32GC) enabling the system to function properly.
During software installation, the SAU serial number is compared with the features
authorization data, to verify the authorized use of enhanced Coral system features.
During regular system operation, the SAU is checked to ensure it remains attached to the
32GC card. However, if necessary, the SAU can be removed for short periods (a maximum
of two weeks) without interrupting system operation. If the SAU is removed for more
than two weeks, the system ceases to process calls.

The Coral system automatically ceases call processing after 14 days for any of the
following reasons:

The SAU serial number does not match the corresponding CFD SAU serial number.

 When starting up the Coral system, ensure that there are no SAU Fault
messages during start-up or SAU Alarms (PI Branch: Root, 1, 1,
15-Controls) due to any one of the following three reasons:
ca missing SAU device
cinappropriate software for this type of system
cmismatched SAU serial numbers on the CFD and SAU device

SAU Unique Serial Numbers

Each SAU is assigned a unique, factory set, system identification serial number which
enables the feature authorizations and Coral generic software version for the Coral
system. Figure 8-17 illustrates the four side views of the SAU, including sample ID
numbers. The left side includes the country code, while the right side includes the unique
serial number. The last digit of the serial number is a verification digit. Any leading zeros,
as well as the verification digit do not appear in the SAU number reported in the PI root
menu.

SAUs for the Coral FlexiCom 6000R (HSB)

For Hot Standby systems, the software detects the information embedded on both SAU
devices (one on each 32GC) and verifies that the same Coral version is loaded on both
SAUs and set for the Hot Standby dual control configuration.
The SAU installed on the right side of the system control shelf is given a different serial
number than the one installed on the left side. The technician must ensure that the SAU
device serial number must match the CFD card serial number, installed on the side panel
of the corresponding MCP-ATS.

Verify that the SAU device serial number (market number and serial number bar codes
32GC Group Controller Card
together) matches the SAU serial number on the corresponding CFD card label,
inserted in the MCP-ATS on the same side of the control shelf.
Otherwise, the system will automatically shut down after 14 days.

Expanded Memory Card

1 General Information
...................................................................................................

The 4/8XMM daughter card is an optional memory card that is mounted on the 32GC
group controller card. It is an expansion memory module containing either 4 MB or 8MB
and is required for added data storage capacity. It also contains the shared memory
capacity utilized by the MCP-ATS and the optional CLA-ATS unit. The 4/8XMM includes
3V lithium battery backup for power protection.
The 4/8XMM card is installed as a piggyback card onto a memory interface connector on
the 32GC and does not occupy its own card slot within the Coral FlexiCom 6000 control
shelf.

4/8XMM Physical Features

Figure 8-18 illustrates the XMM card layout. The 4/8XMM card is a daughter board
installed on the 32GC, therefore its LEDs and reset button show through the relevant holes
in the 32GC front panel (see 32GC Front Panel on page 8-42).
A 3 volt lithium battery provides power to maintain the card memory circuitry. When the
battery does not hold sufficient power, a message is sent to the PI and the battery should
be changed as soon as possible, see Lithium Battery Handling Procedures, page 8-43 and Card
Battery Condition Test on page 3-16.
A memory interface connector on the top side of the 4/8XMM and three holes of screws
allows the optional installation of a second 4/8XMM card placed atop the first 4/8XMM 4/8XMM Expanded Memory Card
card for future configurations.
The 4/8XMM dip switches are not used.

 8.5 CLA-ATS
CoraLINK® Adapter Card

1 General Description
...................................................................................................

The CoraLINK is a Computer Telephony Integration (CTI) Link for the Coral system that
provides an Open Architecture Interface (OAI) to the call processing and management
circuitry. CoraLINK enables external computer applications to monitor call activity, and
establish, manipulate and disconnect calls through the Coral system. Coral systems
installed with the CoraLINK Adapter (CLA-ATS) Card enable the system to function as a
universal communications switching platform for specialized communications
applications. The CLA-ATS interface enables connecting the Coral Control Circuit cards
to an external Ethernet 10/100Base-T LAN computer network protocol.
The CLA-ATS card incorporates the application processor and Ethernet interface circuitry
for the CoraLINK computer-telephony integration (CTI) link and holds a PCMCIA drive
to house the Compact Flash Disk (CFD). The 64MB CFD contains the CLA-ATS factory
loaded software. The CLA-ATS shares the XMM memory expansion attached on the 32GC
card. The Ethernet interface is a RJ-45 LAN connector on the front panel of the CLA-ATS
card.
Although the Coral IPx 4000R and Coral FlexiCom 6000R are Hot Standby systems, the
twin CLA-ATS cards operate in a Standby/Duplicated mode, not offering CTI Hot
Standby operation. Therefore, during common control swaps, the CTI application restarts
without maintaining its current calls and functions and will disconnect active CTI calls.

CLA-ATS CoraLINK® Adapter Card

Additionally, if a CLA-ATS card fails the CTI application will fail and will not invoke a
control changeover.

All Coral systems that include the optional CLA-ATS card, require a 4XMM or
8XMM expanded memory daughter card installed on the 32GC, as the
CLA-ATS card retrieves its memory from the XMM, see 4/8XMM, page 8-55.

 7 Applications
...................................................................................................

In Coral CTI applications, CoraLINK is connected to the Ethernet back-bone along with
the telephony server.
The CoraLink acts as an interface between the Coral system and any CTI server
application for all the services (call, transfer, etc.) and events (monitoring functions) of the
network. The CTI application together with the CTI telephony server manipulate
numerous different call commands from the agent network and translate them into logical
data. The CTI telephony server communicates with the CoraLINK through a single
connection. The CoraLINK then translates that data into logical information for the Coral
system, which processes the calls.
CoraLINK can support up to eight different multiple CTI applications on the network,
any or all of which may be simultaneously directing service requests to, and receiving
status events at any time.
CoraLINK uses TCP/IP protocol and complies with the ECMA 179 and 180 standards.
CoraLINK also supports the Novell TSAPI protocol, the Intel Dialogic CT-connect, and
IBM’s Callpath.

The CLA-ATS should be accompanied by the appropriate software

application. Contact your manufacturer for the required CTI application
and/or price list.
See Chapter 2 in the Coral FlexiCom & Coral IPx Product Description, for
more details.

 8.6 PB-ATS
Peripheral Buffer Unit

1 General Description
...................................................................................................

The PB-ATS cards are the Peripheral Buffer Units, which function as the signal
regenerator for the peripheral shelves since the peripheral shelves can be located in the
same cabinet as the control shelf or physically further, in an expansion cabinet.
Two PB-ATS cards are provided for each Peripheral Shelf Unit in the Coral FlexiCom 6000
systems to provide redundant backup coverage even though one PB-ATS is enough to
control the peripheral shelf unit. The second PB-ATS unit acts as a Standby unit ready to
take over the functions of the Active PB-ATS card.
The Active PB-ATS card provides buffers for the High-level Data Link Control (HDLC),
Pulse Code Modulation (PCM), Clocking and Synchronization signals, exchanged
between the 32GC card and the peripheral bus serving one or two peripheral shelves.
The PB-ATS card also includes circuitry to allow/inhibit the PCM lines to the peripheral
cards, as well as a circuit for signal rate conversion from 8.192 Mbps to 4.096 Mbps for use
in the peripheral shelves and vice versa. The PCM lines are allowed in the Active PB-ATS
card and inhibited in the Standby PB-ATS card. The PB-ATS card transmits and receives
HDLC messages using HDLC highway A or B in accordance with its location in the
peripheral shelf.
A fault in the interface between the PB-ATS cards and the peripheral cards of the
communication channel does not necessitate a switch-over on the control shelf between
the Active and Standby control card sets. It only necessitates the seamless interchange
between the two PB-ATS cards. PB-ATS Peripheral Buffer Unit
Figure 8-25 describes the interface between the control shelf and the peripheral shelves in
configuration type H and H’ (see Hot Standby Configurations beginning on page 6-41 for
configuration types). In this diagram, the peripheral shelves are shown to include two
PB-ATS cards in slots 1 and 2. A PBD-ATS card connects each pair of PB-ATS cards, in
which a connection exists between an even and an odd shelf, and between each 32GC card
and a PBD-ATS card.

In this configuration full duplication until the level of the PB-ATS card exists. The PB-ATS
card in slot 1 supports the HDLC channel A of the peripheral shelf. The PB-ATS card in slot
PB-ATS Peripheral Buffer Unit

2 supports the HDLC channel B. The voice port for peripheral cards is supported only from
the Active 32GC. The Active PB-ATS card provides the HDLC and PCM signals for the odd
shelf via the PBD24S card. A fault in the PB-ATS card is detected by the Active 32GC.

Recognizing Time Slot Configurations

The PB-ATS card defines its time slot operation automatically at 128 time slots or at 512
time slots according to the type of backplane installed on the peripheral shelf unit. The
Coral FlexiCom 6000 incorporates only backplanes which use all 512 time slots. Peripheral
shelves from upgraded systems, may use backplanes that accept only 128 time slots. The
8

PB-ATS automatically recognizes this configuration and adjusts itself accordingly. The

8-80 Common Control Cards Coral FlexiCom 6000 Installation Manual

 time slots arriving from the PB-ATS serve the entire peripheral shelf unit, i.e. the even as
well as the connected odd shelf.
Each Coral FlexiCom 6000 peripheral shelf units may function with a different number of
time slots per unit, i.e. Unit 1 may accept 512 time slots, while Unit 2 accepts 128 time slots.
The existence of a PB-ATS card and its status are reported to the 32GC card via the FC19
redundant cabling to the MPG-ATS.
The number of time slots used per Peripheral Shelf Unit may also be viewed either from
the Sysgen, 5 -PI branch, the UNITS parameter or by viewing the Unit’s PB-ATS front
panel where a time slot 128 or 512 indicator is lit.

Time Slot Transmission

The PB-ATS card transmits 512 time slots PCM at the rate of 8.192 Mbps from the 32GC
control card. A rate conversion circuit converts it to a rate of 4.096 Mbps, which is suitable
for the peripheral cards. The conversion circuit also changes the 4.096 Mbps rate of the
PCM arriving from the peripheral cards to a rate of 8.192 Mbps, which is the operating rate
of the 32GC card.
In the 128 time slot operation mode, the PB-ATS card only switches the first 128 time slots
(of the arriving 512) between the peripheral shelf and the 32GC.

Special Time Slot Cases

Peripheral Shelf Unit #3 is allotted a maximum of 384 time slots out of the 512 time slots
for transmission. The first two quartets of slots for peripheral cards in each shelf of Unit #3
accepts 64 time slots each for transmission, instead of the 128 time slots, and similar to all
other quartets of peripheral slots in the system accepts 128 time slots each for reception.

PB-ATS Peripheral Card Slots

Each pair of PB-ATS cards supports a Peripheral Unit consisting of one or two peripheral
shelves. The PB-ATS cards are essentially Common Control cards residing in a peripheral
PB-ATS Peripheral Buffer Unit
shelf. To function properly, the two redundant PB-ATS or single PB-ATS card must be
located in slots 1 and/or 2 of an even peripheral shelf fitted with a PBD-ATS at the rear of
these slots.
To prevent inserting a PB-ATS card in the wrong slot, the PB-ATS card is contoured
differently than the other peripheral shelf cards. It has rounded corners on the bottom,
similar to the control cards of other Coral systems. The PB-ATS card slides into matching
groves on the tracks in slots 1 and 2. The other peripheral cards have the rounded corner
on the top.
When upgrading older peripheral shelves to a Coral FlexiCom 6000, the upgrade kit
includes a replacement track for slot 2.

 2 Circuit Description
...................................................................................................

HDLC and PCM Highways

The PB-ATS card buffers all the signals necessary to provide HDLC highways and eight
PCM highways for the 512 configuration and 2 PCM highways for the 128 configuration
from the 32GC cards to one or two peripheral shelves.

Each of the highways are separately buffered to the backplane with a driver for
insulation between the channels.

The HDLC (control) and PCM (voice) highways are bidirectional, with signals
received from the 32GC card to the peripheral shelf, and similar signals
transmitted from the peripheral shelf back to the 32GC card. The PCM highways
are translated to/from the 4.096 Mbps rates of the peripheral cards and the 8.192
Mbps rates of the 32GC cards.

Clock and Synchronization Signals

Clock and Synchronization signals are provided by both channels A and B, however, the
PB-ATS selects only one of the channels for a Clock and Sync source to the peripheral bus
via the PB-ATS regardless of from which 32GC they arrive.

A PB Select line, controlled by the 32GC card is connected to both of the PB-ATS
cards. This line determines whether Clock and Synchronization for both
peripheral busses are derived from channel A or B, regardless of which 32GC is
Active. During power up, the PB-ATS in slot 1 is selected to be Active. The Active
PB-ATS may be switched via the UNITS (Sysgen,5) branch in the PI, see Chapter 4
of the relevant Program Interface & Database Reference Manual.
Figure 8-26 illustrates the PB-ATS circuits in block diagram form.

 8.7 PBD-ATS
Backplane Card

1 General Description
...................................................................................................

The PBD-ATS communicates mainly with the MPG-ATS card, so the HDLC, PCM Clock
& Synchronization signals, as well as Power Supplies Alarm signals are transferred
between these cards. Data and signaling communication is established via redundant
streamlined FC19 cables that connect these cards.
The PBD-ATS resides in the rear panel of the peripheral cabinet backplane, on the back
side of
slot 1 and 2, of the peripheral shelves, where the PB-ATS card(s) are installed.

Card Time Slots Configurations

The PBD-ATS card is factory set to supply 512 or 128 time slots to the connected Peripheral
Shelf Unit.
Peripheral shelves are factory set, configured to work with 512 time slots per shelf. In field
upgrades, the PBD-ATS works with 128 time slot shelves. This configuration is
automatically identified by the system.

Communication between Common Control Cards

Card Relationship
The Coral system main processor, MCP-ATS, maintains a constant dialog with the
peripheral devices. The MCP-ATS is interfaced by the 32GC card. The peripheral devices
PBD-ATS Backplane Card

are interfaced by the PB-ATS cards. The 32GC card signaling is carried out by the
MPG-ATS card, located on the backplane behind it, on the rear side of the Common
Control shelf. The PB-ATS card communications are carried via the PBD-ATS card,
connected to the backplane behind it, on the rear side of slot 1 and 2. Figure 8-28
demonstrates this relationship.

1 General Description
...................................................................................................

Card Function
The Coral FlexiCom 6000 system main processor, MCP-ATS, converses through the 32GC
with the peripheral devices via the PB-ATS card(s).
The 32GC card communications are carried out via the MPG-ATS card located on the
backplane behind it, on the rear side of the Common Control shelf.
Both PB-ATS card communications are carried via the PBD-ATS card, connected to the
backplane behind it, on the rear side of slot 1 and slot 2.
The data and signaling communication between the MPG-ATS and the PBD-ATS is
established via various cables that connect these cards, as described above in the PB-ATS
and PBD-ATS sections above.
Each PB-ATS card can support one Peripheral Unit, composed of one or two peripheral
shelves. When a PB-ATS card supports two peripheral shelves, the card(s) are installed in
slot 1 and/or 2 of the first shelf of the Peripheral Unit, with one PBD-ATS on the rear side
of both slots. The connected shelf requires a PBD24S card installed on the rear side of slot
1 to complete the communications to the odd shelf from the PBD-ATS.
The physical connections between the cards is illustrated in Figure 8-28 above.

Slot #1 with a PBD24S on its rear side, (where a PB-ATS is not installed) can
be used to accommodate any Shared Service card, or any card that does not

require I/O connections.

Shelf Identification
Peripheral shelves supported by a PBD24S card are assigned odd numbers by the Coral.
The number assigned is the next consecutive number after the shelf ID# assigned to the
shelf holding the PB-ATS that services this shelf. See Peripheral Shelf Numbering beginning on
page 6-27, for more information on shelf ID.
