This equipment complies with Part 68 of the FCC rules. On this equipment is a label that contains,
among other 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 your right
to file a complaint with the FCC if you believe it is necessary.
The telephone company may make changes in its facilities, equipment, operations, or procedures that
could affect the operation of the equipment. If this happens, the telephone company will provide
advance notice in order for you to make the necessary modifications in order to maintain uninterrupted
service.
If trouble is experienced with this equipment, please contact the supplier at (516)-632-7200 for repair
and/or warranty information. If the trouble is causing harm to the telephone network, the telephone
company may request you remove the equipment from the network until the problem is resolved.
The following repairs can be done by the customer: No repairs allowed.
This equipment is hearing-aid compatible.
It is recommended that the customer install an AC surge arrestor in the AC outlet to which this device is
connected. This is to avoid damaging the equipment caused by local lightning strikes and other electrical
surges.
This equipment is capable of providing user's access to interstate providers of operator services through
the use of equal access codes. Modifications by aggregators to alter these capabilities may be a violation
of the telephone operator consumer services improvement act of 1990 and part 68 of the FCC Rules.

NOTICE: The Industry Canada label identifies certified equipment. This certification means that the
equipment meets telecommunications network protective, operational and safety requirements as
prescribed in the appropriate Terminal Equipment Technical Requirements document(s). The
Department does not guarantee the equipment will operate to the user's satisfaction.

Before installing this equipment, users should ensure that it is permissible to be connected to the
facilities of the local telecommunications company. The equipment must also be installed using an
acceptable method of connection. The customer should be aware that compliance with the above
conditions may not prevent degradation of service in some situations.

Repairs to certified equipment should be coordinated by a representative designated by the supplier. Any
repairs or alterations made by the user to this equipment, or equipment malfunctions, may give the
telecommunications company cause to request the user to disconnect the equipment.

Users should ensure for their own protection that the electrical ground connections of the power utility,
telephone lines and internal metallic water pipe system, if present, are connected together. This
precaution may be particularly important in rural areas.

Caution: Users should not attempt to make such connections themselves, but should contact the
appropriate electric inspection authority, or electrician, as appropriate.

NOTICE: The Ringer Equivalence Number (REN) assigned to each terminal device provides an
indication of the maximum number of terminals allowed to be connected to a telephone interface. The

The FCC Wants you to Know
This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to Part 15 of the FCC rules. These limits are designed to provide reasonable protection against
harmful interference in a residential installation. This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no guarantee that interference will not occur in
a particular installation. If this equipment does cause harmful interference to radio or television
reception, which can be determined by turning the equipment off and on, the user is encouraged to try to
correct the interference by one or more of the following measures:
a) Reorient or relocate the receiving antenna.
b) Increase the separation between the equipment and the receiver.
c) Connect the equipment on an outlet on a circuit different from that to which the receiver is connected.
d) Consult with the dealer or an experienced radio/TV technician.
To ensure continued compliance with specified radio energy emissions limits of FCC Rules, the
following precautions must be observed while installing and operating the equipment:
1. Install the equipment in strict accordance with the manufacturer's instructions.
2. Verify that the power supply and associated A.C. powered equipment are connected to a properly
grounded electrical supply, and that power cords, if used, are unmodified.
3. Verify that the system grounding, including Master Ground, D.C. power system, and equipment
cabinets, is in accordance with the manufacturer's instructions and connected to an approved earth
ground source.
4. Always replace the factory-supplied cover or keep the cabinet doors closed when not servicing the
equipment.
5. Make no modification to the equipment that would affect its compliance with the specified limits of
FCC Rules.
6. Maintain the equipment in a satisfactory state of repair.
7. Verify that emissions limiting devices, such as ferrite blocks and radio frequency interference mod-
ules, are properly installed and functional.
If necessary the operator should consult their supplier, or an experienced radio/television engineer for
additional suggestions. The following booklet prepared by the Federal Communications Commission
(FCC) may be of assistance: "How to Identify and Resolve Radio-TV Interference Problems."

1 System Description
...................................................................................................

Capacity
The Coral IPx Office is the first Coral product to integrate traditional telephony and
VOIP networking abilities in the same basic system. The Coral IPx Office is a small,
table or rack-mounted PABX, designed to fit in the low to medium range of the private
PBX telephone market. IPx Office supports all the Coral FlexiCom and Coral IPx
family features. The IPx Office is a communications platform that offers Voice over
IP with all of the features and capabilities required in today’s business environment.
The number of wired stations supported by the IPx Office configuration depends on
the combination of SLTs (Single Line Telephones) and keyset units. See the Product
Description.
The Coral IPx Office can be expanded using an additional expansion unit. Up to two
expansion units (combination of IPx 500X and IPx 800X) can be connected to one
IPx Office unit. The IPx 800X expansion cage uses standard Coral FlexiCom
300,400,5000,6000 and Coral IPx 800,3000,4000 peripheral cards. The IPx 500X
expansion cage uses the special form factor XXXipx cards. The IPx Office operates
from a standard wide input 100-240VAC, 47-63Hz or from a -48VDC source.

 Circuitry
The Coral IPx Office includes digital communications switching based on Pulse Code
Modulation (PCM) switching technology. The active circuitry of the system is
contained on the MCB Office card and removable cards.
The active circuitry of the IPx Office 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 and an
outlet to the IP world. The peripheral circuitry provides the hardware necessary to
establish those connections. Instructions from the common control to the peripheral
circuitry, and status information from the peripheral circuitry to the common control
are passed through the group controller, which provides driver and time slot
interchange functions for the PCM highways and the HDLC channels.
The common control is further divided into shared service, the group controller, the
main central processor, connection to the IP and the MRC.
The shared service circuitry is integrated into the MR / RMI / U-MR / U-RMI Office
peripheral card, which 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.

8 Ground Wiring
...................................................................................................

Proper system grounding is critical to reliable system operation. System grounding is

only as effective as the ground point itself. To ensure adequate protection from
interference by radio frequency energy, electrical impulse noise, and lightening or
power line surge, the building electrical ground point must comply with grounding
recommendations of the National Area Code, Article 800, and/or applicable local
building and electrical codes.
The object of ground circuit design is to establish a low resistance path to the ground,
and to conduct a multitude of currents in such a way as to minimize the interaction of
any two or more currents. In essence, the ground connection is used as a common
conductor for many circuits: some carrying wanted signals, and others carrying
unwanted signals. The same ground that carries small networking currents must also
carry unwanted radio frequency energy, impulse noise, and lightening surges that
might otherwise interfere with system operation.
The ground connection includes an M4 threaded terminal pole that is fixed onto the
surface of the rear panel (by the manufacturer), a serrated washer between each
terminal connection, a flat washer, and an M4 nut.

Electrical Hazard. Incorrect ground wire connections to the system can cause shock,
burn, or death.
•Verify that the ground wires are 10 AWG stranded conductor.
•Verify that all ground connections are made directly from the cage ground connection to
the master ground.
•Do not interconnect cage ground terminals between the Coral units.
•Ring terminals retain wires onto the terminal lug when the connection is loosened.
Verify that all ground wires include ring terminals at both ends.
Equipment Installation

•Connect only a Protective Earth (PE) to the Coral system.

Do not connect a separate Telecommunications Reference Conductor (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 system. Any ground connection of equipment related to
the switching Coral system should ultimately connect to the master ground.

2-18 Hardware Installation Procedure Coral IPx Office Installation Manual

 The unit ground wire is connected to the unit in the rear panel. See Connecting the
Ground Wire to the Unit, page 2-19. For instructions on how to ground the
customer-supplied MDF unit, see Grounding the MDF Unit, page 2-20.

Connecting the Ground Wire to the Unit

The cage ground connection includes one serrated washer, a flat washer, and one
hexagonal nut assembled on the terminal connection. See Figure 2-7.
Connect the ground wire to the cage as follows:
1. Remove the hexagonal nut and flat washer from the ground terminal. Do not
discard.
2. Insert the serrated washer onto the ground terminal.
3. Insert the ground wire ring terminal over the serrated washer.
4. Insert the flat washer onto the ground wire ring terminal.

9 Strapping the Configuration Jumpers

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

This section describes how to remove and insert the shorting plugs of the various
jumpers. In the Coral IPx Office system, some of the peripheral cards include jumpers
that configure the shared service functions. For a specific card description, see
Chapter 9, Shared Service Cards and Chapter 10, Peripheral Cards. For a specific
description of these cards, see the Peripheral and Shared Service Cards Installation
Manual. This must be done before inserting the peripheral cards.
To set the configuration jumpers:
1. Connect the static dissipating wrist strap connector to the cage and put on the
strap.

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 cage while handling circuit cards. See Figure 2-11 on page 2-24. Hold circuit
cards by their edges and avoid touching contact surfaces. Handle with care and do not
drop.

Synchronization Jumpers
Defining different cards or cages by the same synchronization classification
could lead to system disruption. Verify that the synchronization jumpers are
strapped as described in Chapter 10, Peripheral Cards.
Expansion Cage Identification Jumpers
Defining two expansion cages by the same cage number could lead to
system disruption. Verify that the cage numbering jumpers are strapped as
described in Chapter 6 of the Coral IPx 500 Installation and Hardware
Reference Manual and/or the Coral IPx 800 Installation and Hardware
Reference Manual.

2

2-24 Hardware Installation Procedure Coral IPx Office Installation Manual

 4. Align the edges of the circuit card with the card edge guides in the card cage,
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 front
panel 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.
Never place a card in a slot other than the dedicated one. Refer to Table 2-6 to
determine peripheral interface card types.

Table 2-6 lists the peripheral interface card types that may be inserted into each card
slot in the Coral IPx Office system.

Peripheral Interface cards listed in Table 2-6 may require changes to

jumpers on the card that determines the electrical characteristic or
operation of each interface circuit. Refer to specific card descriptions
in the Coral Service and Peripheral Cards Installation Manual for
details.

2 Memory Lithium Battery Condition Test

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

If the start-up tests detect that the voltage level of a lithium backup battery on the
MCB Office is insufficient to reliably maintain the memory contents in the event of
power failure, the following messages will appear:
MCB Office - BATTERY LOW

This message indicates that the MCB Office card battery has an insufficient voltage
level. In this event, the Coral system database is in jeopardy of being lost during a
power failure. If this message appears, the database should be saved and the battery
replaced at the first opportunity.
To ensure that the system database is not lost, save the database to the IMC8/IMC16
card via the database controls branch of the system database (ROUTE: ROOT, 0, 10, 2,
2, 0). For details, see System Database Control, page 4-5. If the system loses power or is
reset for any reason and the database is lost from memory, the system will copy the
database from the IMC8 card into database memory as the system restarts.
Once the system database is safely saved on the IMC8 card, power to the Coral system
may be turned off at a time that will cause the least disruption of service to the user.
At that time, the battery on the MCB Office may be replaced and the system restarted.

To replace the lithium battery, carefully raise the battery holder clip and then
insert the new battery with the + (positive) symbol appearing on top. Do not
apply too much pressure to the battery holder clip as this could cause the
clip to snap.

Explosion and Environmental Hazards.

There is a danger of explosion if the battery is replaced incorrectly.
Common Control Test

Replace the battery only with the same or equivalent type recommended by the
manufacturer.
Dispose of used batteries according to requirements specified by the battery
manufacturer and/or local regulatory agencies.

 3.3 Peripheral Interface Card Initialization

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

This section describes how to initialize the peripheral cards. Perform this section only
after the MCB Office control card in the IPx Office has been initialized properly. If the
peripheral cards are inserted before the IPx Office system has initialized, they will not
initialize properly, either.
The card installation is described on Rules for Inserting a Coral Circuit Card, page 3-10.
The IPx Office system peripheral cards installation and initialization procedure
includes the following steps:
1. Preparing for Initialization
2. IPx Office Unit Initialization
3. First Expansion Cage Initialization
4. Second Expansion Cage Initialization

Peripheral Interface Card Initialization

3

Coral IPx Office Installation Manual Initial Power-up Tests 3-9

 Rules for Inserting a Coral Circuit Card
1. Connect a static dissipating wrist strap connector to the cage and put on the
strap. See Figure 2-11 on page 2-24.

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

electro-static discharge (ESD). Always wear a static dissipating wrist strap connected to
the unit while handling circuit cards. Hold circuit cards by their edges and avoid touching
contact surfaces. Handle with care and do not drop.

2. To insert a circuit card completely into its slot, 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.
3. Push against the front panel of the card until it 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.
Never place a card in a slot other than the dedicated one. Refer to Table 2-6 on page
2-27 to determine peripheral interface card types.
Peripheral Interface Card Initialization

4. On the front panel of the peripheral card, verify that the red diagnostic LED(s)
(near the right side of the card) illuminates. The LED remains illuminated
continuously until the card receives its database from the system. After a few
seconds, verify that the LED extinguishes. An extinguished diagnostic LED
indicates that the card has initialized properly.
If the LED remains illuminated continuously for more than two or three
minutes, either there is a conflict between the system database and its
authorizations, or the card may be faulty. See Table 6-1 on page 6-3, or refer to
the Coral Service and Peripheral Cards Installation Manual for further details.
3

3-10 Initial Power-up Tests Coral IPx Office Installation Manual

 5. Attach the Program Interface (PI) device cable to the KB0 programming port
connector on the front panel of the IPx Office unit 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 Chapter 6 of 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. Access the card list branch of the PI (Route: CLIS) to verify that the cards are
properly recognized and initialized by the IPx Office MCB Office processor.
The following table appears on the PI terminal:
shelf/slot I_TYPE P_TYPE CDB version subversion status
1 / SLOT No. CARD_NAME CARD_NAME XXX XXX XXX ACTIVE

The following is an explanation of the CLIS fields:

Shelf Number.......... The IPx Office unit is designated shelf # 1; the first expansion
cage is labeled shelf #2; the second expansion cage is labeled
shelf #3.
Slot Number............ Identifies the slot location of the indicated card for display. In the
IPx Office unit, the range of slot numbers is 2-11; in the
expansion cage, the range of slot numbers is 1-10.

There are five physical card slots located in the rear section of the
IPx Office unit. However, the PI recognizes each physical slots as two
separate slots (slot 2-3, slot, 4-5, slot 6-7, slot 8-9, and slot 10-11).

Peripheral Interface Card Initialization

I_TYPE ................... This field should show the required card name.
If the I_Type lists a different card type this indicates that the card
slot has been previously initialized by a different card type. That
card must be relocated to a clear card slot (where the I_Type field
shows NO_CARD) or the current card slot assignment must be
cleared throughout the PI.
P_TYPE .................. Shows the card type currently located in the slot.

1. In the expansion cages, verify that the PS Office power switch is in the OFF
position (turned downwards).

Before proceeding, verify that all power supply units within the expansion
cages are turned OFF. If the expansion cages are turned ON before the
IPx Office unit, the peripheral cards within the expansion cages will not
initialize properly.

2. Check the position of shared service and peripheral interface cards that will be
inserted into the system card cage. Observe any order previously directed or
any established convention of the distributor. See Inserting a Coral Peripheral
Card, page 2-24 and use the following card placement diagrams:
„ Coral IPx Office Card Placement, page 2-28

 4.1 Generic Feature Software
Upgrade

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

The Coral IPx Office is delivered to the site with factory-loaded software on the IMC8
or IMC16 card. The IMC8 card is an 8MB flash memory card. The IMC16 card is a
16MB flash memory card. See IMC8 and IMC16 Flash Cards, page 8-33 for details. The
IMC8 card is installed on the front panel of the IPx Office system.
The software initialization procedure is described in Common Control Test, page 3-5.
The IMC8 and IMC16 cards contain three types of data:
„ Generic Feature Software Version and Boot Code
„ Authorization
„ Database Backup
The IMC8 or IMC16 card can be inserted into a PC slot using any PCMCIA
application adapter for loading a new Coral software version.
Whenever an updated version of the IPx Office software is released, the upgrade is
delivered to the sites either on 3.5” diskettes, via e-mail, or via other electronic media
file transfer applications. The upgrade is contained in a self-extracting compressed file
that is specific for the site.

Generic Feature Software Upgrade

The upgraded generic feature software must be extracted by a PC using the FMprog
tool, and then written from the PC hard disk onto the IMC8 and IMC16 cards. The
FMprog is a tool for Coral dealers who install, upgrade and maintain Coral systems
using flash memory cards. See the FMprog PC-Utility Reference Manual. This
reference manual describes how to install and operate the FMprog-Utility.

2 Upgrading Using the FMprog-Utility

...................................................................................................
0

Use FMprog version 5.xx and above. Otherwise, the Coral will not initialize.

The upgrade of the generic feature software involves the following main steps:
„ Installing the FMprog-Utility (version 5.xx and later)
„ Extracting the new Coral generic feature software file into the PC hard disk
„ Programming the new generic software upgrade to the IMC8 or IMC16 card
The FMprog-utility can be used to backup the Coral software into PCMCIA cards. The
backup file is in a binary format and includes all the software components of the
specific Coral system from which it was copied, including the Coral generic software
version, the switch authorization, and the database. Copies should be made and
maintained at every customer site. Each site has its unique software configuration,
including its main software version, switch authorization and database, as well as its
specific Software Authorization Unit (SAU) information. Copies of all system files
exist and are available for use via the FMprog-Utility, if they are needed.
Use the FMprog-Utility to:
„ Manage your new database versions
„ Load the Coral generic version, authorization and database information on to
flash memory cards
„ Extract version, authorization, and database information from source files

3 Installing an Upgraded IMC8 / IMC16 Card

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

This section provides instructions on inserting the IMC8 / IMC16 flash memory card
after it has been programmed with a new or upgraded software version.

Creating a Binary Backup of the Database

Before installing an IMC8 or IMC16 card with a new generic software version, it is
strongly recommended that you make a binary backup of the database. The binary
backup must be done 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. See
the Database Binary Backup PC Utility Reference Manual for further details.

Installing the IMC8 / IMC16 Card

Before each installation or removal of an IMC8/IMC16 card from the IPx Office unit,
press the RESET button on the front panel of the IPx Office unit.

1. Press the Release button on the PCMCIA drive of the PC to remove the new
IMC8/IMC16 card.
2. Press the Reset button on the on the front panel of the IPx Office unit.
3. Press the Release button on the front panel of the IPx Office unit to remove
the old IMC8/IMC16 card.

Generic Feature Software Upgrade

4. Insert the new IMC8/IMC16 card containing the upgraded generic software
version.
5. Press the Reset button on the front panel of the IPx Office unit.
6. Verify that the following two messages appear on the PI device:
For SERVICE/SOFTWARE installation menu HIT <CTRL I> NOW
*************************
CHK RAM
END CHK RAM
Custom Init Code...
.
.
The second message may appear after two or three minutes, following several short
messages that appear during system start-up:
4

CCS is on the air......

Coral IPx Office Installation Manual Software Installation Procedure 4-3

 (ROOT)
CCS xx.xx.xx
Copyright (c) 2001-xxxx...............
NAME - (site name)
SAU # -

After the second message appears, the system has initialized properly and is capable
of processing calls. After entering the password, the version level of the generic
feature software is indicated where the x's appear in the line that reads CCS xx.xx.xx.
7. The new IMC8 card does not include a backup of the current database. To
make a backup of the database, perform the procedure described in Saving to
IMC8 or IMC16, page 4-6.

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 the version that is
authorized by the SAU.
•An SAU is removed from the IPx Office side panel.
Relevant system messages appear on the PI automatically warning that the system will
not operate without the proper SAU.

The program contained on the IMC8 permits the generic software to function even if
the serial number of the SAU is incorrect, or the SAU is absent entirely. If, however,
the Coral determines that the SAU is missing or not correct, a message appears during
the procedure warning that the system will not operate without the proper SAU. This
Generic Feature Software Upgrade

provision allows the generic feature software and/or feature authorizations to be

upgraded on an IMC8 card in another distant system, then installed at the proper
system by replacing the existing IMC8 card from the other distant system containing
the upgrade.

4 Upgrading the UGW Software

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

The Universal GateWay (UGW) software is embedded on the MCB Office card. To
upgrade the UGW software, see TBD?????

 4.2 System Database Control

During normal system operation, the configuration database may be saved to a file on
the IMC8 / IMC16 card for permanent storage. The system may also be programmed
to save the database to IMC8 / IMC16 automatically on a daily basis, at a particular
time.
A saved database file may be loaded at any time into the system database memory.
This is a way to restore the database into the RAM of a new MCB Office (and
DBM-X) control card.
Once the database in the system has been constructed, copy the database onto the
IMC8 / IMC16 card. For more detailed information, see Chapter 21 of the Program
Interface Reference Manual.

2 Saving to IMC8 or IMC16

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

The Database Save feature allows the system database to be copied to IMC8 at any
time. The procedure is as follows:
1. Verify that the system time and date are correct (press Control-T to check).
Update through the Time and Date branch (Route: TIME) of the system
database if necessary.
2. From the Database Flash menu press 0 to save the database to a file on the
IMC8 card. The system prompts for the selection of a destination file number,
either DB0.DEF or DB1.DEF, with:
DEST FILE (0,1) - [0]
The DB0.DEF file may be saved automatically at a preset time each day and
so is usually more up-to-date than the DB1.DEF file. See Automatic Daily
Backup, page 4-11. The DB1.DEF file is referred to as the technician’s 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 the table below, to begin saving the system database
to a file. The default entry is 0 or DB0.DEF.

Database File Name PI Entry File Description

4. When the prompt EXECUTE (Y/N) - [N] appears, type Y to begin the save
process, or N to cancel and return to the Database IMC8 menu. The PI
command prompt (*:) will return immediately, but the system will process the
command as a background (low priority) task.
System Database Control

Saving the database to a file generally takes several seconds. While the
database is being saved, it is important to note that changes to the system
configuration (such as: changing the system to Night Service, setting a Call
Forward or Do Not Disturb instruction at a station, even turning on or off
Background Music at a key set) are disabled until the database save process
is completed.

If the system is unable to save the database, one of several messages will be generated
by the system.

3 Loading (Restoring) from IMC8 or IMC16

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

A system database stored in IMC8 can be loaded into the database memory on the
MCB Office card at any time.

Loading the database from IMC8 generally takes several minutes. During
this process, the Coral system is non-operational.

Loading a database can be useful for installing the database of an existing system into
the database memory of another system that will have 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). The database can then be
loaded at a convenient time at the intended site.

Loading a database from IMC8 into the system database memory destroys the original
database information stored in the database memory and overwrites it with information
in the IMC8 database file. Once overwritten, the original database cannot be recovered.

1. From the Database Flash Menu, press 1 to load a database from IMC8.
The system will display the following message:
CAUTION: Database contents will be lost & system will
restart !!!
Proceed with restore (Y/N) ? [N]
2. If Y is selected, the system prompts to select a source file number, either
DB0.DEF or DB1.DEF with:
FILE (0/1) - [0]
3. Press 0 or 1, according to the table below, to begin loading the database stored

The following prompt appears:

EXECUTE (Y/N) - [N]
4. If you type Y, the system goes through the following retrieval conditions check
4

sequence:

4-8 Software Installation Procedure Coral IPx Office Installation Manual

 a. Verify that the internal flags are present in the database to be loaded.
b. Verify that the database is not corrupted (the system executes the checksum test
procedure).

If the procedure checking the database ( DBS) retrieval conditions found the
above conditions fulfilled, the following message will appear:
Restore DBS.......
Upon finishing the restoring procedure, the system reports:
Restore Successful
Next, the system will execute the partial initialization.
If the conditions mentioned above were not met, one of the following
messages will be displayed:
Operation denied DB0.DEF is not O.K.
or
Operation denied DB1.DEF is not O.K.
If only one backup file was present when the technician requested DB1.DEF
retrieval, the following message appears:
Operation denied, Load DBS available only to DB0.DEF
5. Press Y to begin loading the database, or press N to return to the Database
menu.
Loading the database from a file generally takes several minutes. When the
database has been loaded, the system performs a partial initialization and

5.1 Main Distribution Frame (MDF)

This chapter describes the MDF and the pinout connections to the cage and external
equipment. For hardware installation instructions, refer to Hardware Installation
Procedure, page 2-1.

This chapter describes connections between the Coral IPx Office unit and
the customer-supplied MDF. Some of these connections can be made
directly from the Coral IPx Office unit and the facilities’ infrastructure, without
the use of an MDF. It is the customer’s responsibility to decide when to do so.
For information on connections between the IPx 500X expansion cage and
the MDF see the Coral IPX 500 Installation Procedure and Hardware
Manual.
For information on the Coral IPx 800X expansion cage and the MDF, see the
Coral IPx 800 Installation Procedure and Hardware Manual.

The MDF is often located adjacent to other signaling systems, such as:
„ Paging and public address systems
„ Voice messaging systems
„ Alarm and monitoring systems
„ Closed circuit television
„ Property management systems

Main Distribution Frame (MDF)

„ Building and energy management systems
5

External Connections 5-1

 Therefore, care should be taken to plan the MDF layout before fastening components
to the rack or table-mounted surface, such as:
„ Network (LAN/WAN) Connection
„ Trunk circuits
„ Wired and wireless station equipment
„ Database programming terminals
„ Report printers
„ Music and/or audio sources
„ External public address or paging equipment
„ Recording devices

Connections to most telecommunications interfaces of the Coral IPx Office unit are
made via:
„ Standard 25 pair Input/Output (I/O) Champ (telco) connectors located on the
front panel of the full size peripheral cards. See Table 5-1 and Figure 5-1
„ RJ-45 connectors located on the front panel of full and half size peripheral
cards. See Table 5-1 and Figure 5-1.
For information on LAN/WAN connections, see Chapter 11, System Networking.

Tip:
It is recommended to terminate all the I/O connectors available in the
system on punch blocks at the MDF even if some cables are not initially
used. This saves time and effort when the system expands.

1 Station Equipment
...................................................................................................

Wired Stations
Each station peripheral card provides an I/O ChampTM connector.
Connections to Coral IPx Office system station equipment are established by
cross-connecting the station circuit from the appropriate Coral IPx Office I/O cable
punch block to the corresponding station wiring punch block.
Table 5-2 lists the various station interface cards available for the Coral IPx Office
system, the type of station equipment that the card supports, and the number of wire
pairs required by the station interface.
Station wiring between the Coral IPx Office system MDF and the station equipment
should contain at least two, and preferably three wire pairs to ensure adequate wiring
capacity. At the station location, the station wiring should be terminated with a
modular, six position, telephone jack, containing at least four conductors (pins 2, 3, 4,
and 5).
Figure 5-2 illustrates typical jack configurations with wire designations for four station
types:
„ 2-wire single-line telephones SLT and digital station sets (FlexSet, APDL,
CPA) need only connect Tip [T] and Ring [R] or <UpA> and <UpB> as
shown.
„ FlexSet 280 series or FlexSet APDL units with PEX or PEX+APA need an
External Equipment

extra 2 wires when power is supplied through the line connector. The polarity
of this connection is irrelevant. When using the TPS (single unit Telephone
Power Supply), no additional wires are required.
For peripheral device installation, refer to the Coral Terminal Equipment Installation
Manual”.
To prevent a potential shock hazard to station users and damage to the system, make
sure that station circuits extended over cables that exit the building are adequately

 2 Trunk Circuits
...................................................................................................

Generally, trunk circuits are connected to the Coral IPx Office system simply by
cross-connecting the trunk interface circuit of a Coral IPx Office trunk card to the
point of demarcation where the trunk circuits from the Telephone utility Company
(TELCO) appear. For more specific data regarding all trunk types supported by the
Coral IPx Office systems, refer to Peripheral Card Description, page 105. Refer also to the
Coral Service and Peripheral Cards Installation Manual.
Protective devices are regularly provided by the TELCO on circuits originating
outside the building. Determine if the TELCO protective devices meet the
specifications provided in Protection Devices, page 511, and if necessary, install
secondary protector devices that meet these specifications. To be effective, the
protective devices, whether TELCO or customer provided, must be grounded to the
same ground point as the IPx Office system. Figure 5-3 illustrates typical trunk circuit
wiring from building entrance to the Coral IPx Office system.

5.3 Protection Devices

1 Introduction to Primary and Secondary Protection Devices

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

Any circuit connected to the Coral system that is exposed to lightning or electrical
hazards must be protected with approved lightning and surge protection devices to
avoid potentially lethal hazards to all users.

Secondary protection devices should be installed on any circuit requiring primary

lightning protection, which connects electrically to an interface of the Coral system.

Lightning and over-voltage arrestors are used to protect the user and the system from
lightning and other electrical hazards that may occur on external circuits connected to
the system.
Any cable that passes through open air, under open ground (i.e. across parking lots,
fields, road beds, etc.), across a bridge, or along the exterior or under the non-metallic
roof of a building, is exposed to lightning and electrical hazards.
Telephone circuit protection devices fall into two distinct design categories:

„ Primary (lightning) protection devices that limit voltages on a telephone circuit

below levels which do not present a hazard to the user. (Table 5-4 lists
Protection Devices

minimum specifications).
„ Secondary (surge and impulse) protectors that further limit voltages on a
telephone circuit to prevent damage to electronic equipment. Table 5-5 lists the
specifications.
Primary protection absorbs the major impact of infrequent, but dangerous,
catastrophic surges, while secondary protection suppresses constantly occurring
5

External Connections 5-11

 impulses. These impulses, while not dangerous, can cripple valuable, and in many
cases, essential, communication facilities.
Generally, leased or switched circuit facilities provided by the local telephone utility
company are equipped with primary protection devices installed with the circuit.
However, privately owned aerial or buried cable feeding from one building to another
may not be equipped with protection devices. Always consult with whoever provided
the circuits to determine whether protection devices are present, and if so, what type.
Never assume that protection devices have been provided by another party, or that
existing protection devices are adequate.
The secondary protection must include a leakage current protector in series with every
wire, tip and ring, on every port that is either connected to the public telephone
network, or to any cable located outdoors. The requirement is in accordance with UL®
Specification 60950, Third Edition or CSA C22.2 No. 60950. The required protectors
can be mounted directly on a 66 block in the MDF.

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

To prevent serious damage to the Coral IPx Office system, the analog trunk and station
circuits whose cables are laid outside the building, must be protected from the
electrical peaks caused by lightning. Magazine 10 surge arrestors must be mounted on
the MDF where telephone circuits are cross-connected.

5.4 Power Fail (PF) Transfer Circuits

With the installation of trunk cards to support the PF (Power Fail) transfer option, four
trunks per trunk card may be directed to station sets if power to the Coral IPx Office
system is interrupted. This arrangement, referred to as power failure transfer,
completely bypasses the system, allowing specific stations to originate outgoing calls
and/or continue answering incoming calls.

5.5 Data Communication Ports
RS-232E

The Coral IPx Office switching system is capable of switching digital data information
as well as voice signals.
Coral IPx Office system data communication devices are available for packet
switched data for low volume applications. The packet data communication devices
are provided using the APA (Application Processor Adapter) or APDL (Applications
Processor Data Link). The data communication devices provide a serial interface
wired as Data Communication Equipment (DCE). That is, transmit data is data that is
sent to the APA/APDL, and receive data is data that is received from the device.
The APA provides a proprietary data link to an external applications processor. The
link uses an asynchronous RS-232E (V.24) serial data interface, operating at a data
rate of up to 19.2Kbps. The interface appears at an RJ-45 jack connector on the rear
panel of the and FlexSet 280S/281S/APDL with APA or PEX+APA.
Through the link, a proprietary signaling protocol allows the Coral system master
processor to send call status messages to the applications processor, and the
applications processor to send call control instructions to the APA/APDL. Application
processors available for the Coral system include the Computerized Attendant
Position (CAP), the ACD group supervisor and management position, Coral
CallMaster (CCM), Coral World Wide Office (WWO), TAPIdriver, GKT PC-Utility,
or any other application that complies with proprietary API products.

Data Communication Ports RS-232E

Use the following RS-232 cables:
„ Catalog no. 7244-6914055 for FlexSet 280S/281S/APDL with APA or
PEX+APA with APA or FlexSet 80 (GKT).
Figure 5-6 lists the pin designations for the RS-232 interface of the APA/APDL.

 Rear Side
The rear side of the unit houses the peripheral cards and the power supply card. See
Figure 6-4. When installed, the front panels of the peripheral cards and the power
supply card completely overlay the rear section of the unit. Since the front panel of all
cards installed from the rear are RFI protected, the unit cover does not need to protect
the rear side of the unit. Therefore, the cards can be installed and removed without
removing the unit cover.
The rear side includes the slots for inserting the power supply card and the peripheral
cards. The peripheral card slots are designated slot 2-3, slot 4-5, slot 6-7, slot 8-9, and
slot 10-11. (Each card slot is recognized by the programming interface as two separate
slots.)
The rear side is designed to house full-size as well as half-size cards. See Peripheral
Card Description, page 10-5. The front panel of the half-size cards come in three different
sizes. For that reason, some of the half-size cards must be installed in specific slots.
See Table 2-6 on page 2-27 for further detail. Slot 2-3 and slot 4-5 house the full-sized
cards. Slot 6-7, slot 8-9, and slot 10-11 house the half-sized cards.
When any of the peripheral slots are not used, the openings must be covered by an
appropriate blank panel. See Blank Panels, page 6-16.

Electrical Hazard. Exposure to live circuits could cause shock, burn, and death. Do not
operate the IPx Office system without covering empty card slots with a protective panel.

The rear side also includes the unit ground terminal including, the M4 threaded pole,
a serrated washer a flat washer and an M4 nut.

The rear section of the unit interior includes the peripheral card slots and the power
supply slot. The slots are aligned horizontally from top to bottom. The top two slots
(slot 2-3 and slot 4-5) house full-size cards. A vertical partition is positioned beneath
these slots forming an additional three slots (slot 6-7, slot 8-9, and slot 10-11) that are
used to house half-sized cards.

Figure 6-10 IPx Office

Rear Section without
Cards Installed

Card Slots
Guides aligned horizontally along the rear section of the IPx Office unit enable the
cards to be connected to multi-pin connectors mounted on the MBP Office. The guides
and associated connectors comprise a card slot. See Figure 6-10. The connectors
provide metallic paths from the cards to the various power and signal buses of the
system and for peripheral cards, to the Input/Output (I/O) connectors.
General System Description

These slots are designated slot 2-3, slot 4-5, slot 6-7, slot 8-9, and slot 10-11, because
the Program Interface (PI) recognizes each physical slot as two separate slots for the
purpose of system programming.

Power Supply Unit

The IPx Office includes one AC or DC PS Office power supply unit located on the left
side of the cage. The power supply unit is attached to the unit with two screws that
ensure that the unit is grounded. These power supply units are described in detail in
6

Chapter 7, Power Supply.

6-14 Cage Description Coral IPx Office Installation Manual

 Peripheral Cards
The IPx Office unit includes five peripheral card slots in the rear section. These card
types are described in Chapter 10, Peripheral Cards, and in greater detail in the Coral
Service and Peripheral Card Manual.

Configuration Jumpers
The jumpers of the IPx Office unit that are configured at the customer’s site are located
in the peripheral cards. For further information, see The Service and Peripheral Card
Installation Manual.
0

I/O Connectors
Every peripheral card includes an I/O connector to interface with the MDF. The I/O
connections for each peripheral card slot are provided directly from the front panel of
the card to the MDF. The I/O connectors are either Champ or RJ-45:
„ Champ connectors include female, 25 pair AMP™ Champ™, or Amphenol®
Microribbon® type connectors that appear on the front panel of many
peripheral cards (for example, 8SLS Office, 16SFT Office, etc.)
„ RJ-45 jacks are mounted on the front panel of many of the peripheral cards
(for example, the UDT Office, T1 Office, PRI-30 Office cards, etc.) Mating
male RJ-45 connectors should be industry standard.
Refer to the specific card tables in Chapter 5, External Connections for I/O connector
pin assignments.

Expansion Connector
The expansion connector is positioned on the ESIM Office card. The IPx Office General System Description
expansion cable can be connected to an expansion cage only if the ESIM Office card
is inserted in slot 8-9. See Interconnecting the IPx Office Unit and the Expansion Cage, page

Coral IPx Office Installation Manual Cage Description 6-15

 Blank Panels
Blank panels are used to cover peripheral card slots that are not occupied by a
peripheral card. The blank panel covers the slot and prevents the insertion of foreign
objects into the system, thus preventing inadvertent shock or malfunction. There are
four blank panel sizes. See Table 6-2 and Figure 6-11.

5 Heat Removal
...................................................................................................

Heat is removed from the IPx Office unit by forced convection. Three DC fans,
mounted on the inside of the right panel, draw cool, ambient air from the left side of
the unit. The cool air absorbs the heat from the circuitry inside of the unit, and is then
expelled through the fans via the right panel. In order for the unit to be cooled
effectively, the cool ambient air must be drawn in from the left panel, only.

Operating the IPx Office unit while the cover is not closed will cause the cool air to be
drawn into the fans from above, bypassing the internal circuitry of the unit. Heat buildup
within the unit could cause damage to the system. Do not operate the unit before closing
the cover.

3 Suggestions for Peripheral Card Distribution

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

Main Unit
The Coral IPx Office main unit is a non-blocking system. The IPx Office system
incorporates 1024X1024 timeslots. The timeslots are distributed as follows: slots 2-3,
4-5, 8-9, and 10-11 share the time slots 0-127 (128 time slots). Slot 6-7 uses time slots
128-255 (128 time slots). See Table 6-6.

Table 6-6 Timeslot

Distribution in Coral Peripheral Card Slots or Number of Peripheral Number of
IPx Office Main Unit Shelf # Function Card Slots Timeslots

2-3, 4-5, 8-9,

1 4 128
10-11

1 6-7 1 128

Expansion Cages
Both expansion cages (IPx 500X and/or IPx 800X) share time slots 256-639 (384 time
slots) between a maximum of 24 card slots. The timeslots are evenly divided to three
groups of 128 timeslots and distributed between slot sets, as detailed in Table 6-7.
Therefore, slots 1-4 share 128 timeslots, slots 5-8 share 128 timeslots, and slots 9-10
in IPx 500X or slots 9-12 in IPx 800X share an additional 128 timeslots. Figure 6-28
illustrates the distribution of PCM highways in Coral IPx Office systems.
System Configuration Options IPx Office

To ensure efficient use of timeslots of the IPx 500X and IPx 800X expansion cages, it
is recommended to distribute heavy consumer cards (cards with a large number of
ports: 30T, T1, PRI-30, PRI-23, or UGWipx 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 Card Slots in Table 6-7.

If three PRI-30 cards are installed, it is recommended that one of them be

installed in any one of slots 1-4, the second card in any one of slots 5-8, and
the last card in any one of slots 9-10 in IPx 500X or slots 9-12 in IPx 800X.

Figure 7-9 presents a block diagram of the PS Office DC power supply.

Power Input Section

The DC input includes a passive filter, inrush current, and a power switch. The DC
input is protected against reverse polarity.

DC Output Power
The DC to DC converters convert the –48VDC power to the following outputs:
„ +5VDC
„ 3.3VDC
„ -48VDC

-48VDC Output Power

The PS Office DC also filters and limits the -48VDC input to feed the peripheral card
slots.

Ripple and Noise

Filtering circuitry minimizes ripple and noise on the –48VDC feed to the peripheral
cards. The filtering circuitry produces an output voltage that is approximately 0.5V to
1.0V lower than the input voltage -VIN to the PS Office DC.
If the voltage input is less than –38±0.5VDC or greater than –58±0.5VDC, then the

PS Office DC Power Supply Unit

power supply shuts down. The power supply will turn on when the voltage is less than
–58±0.5VDC or greater than –45±0.5VDC. 7

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

The common control cards include the MCB Office, the IMC8 or IMC16 flash card,
the compact flash card, the hard disk, the MRC card, the LED Office card, and the
DBM-X card. The MCB Office card acts as a mother card to the other cards.
The MCB Office card contains the following embedded circuits:
„ Main Control Processor (MCP) is the "core" of the IPx Office common
control. The MCP includes memory management circuitry, local bus interface
and database memory (protected against power loss by a long-life lithium
standby battery). It also provides a real-time clock and hosts the Software
Authorization Unit (SAU). The main processor receives status messages from
ports in the system and determines the appropriate response based on
programming entries contained in the system database. The MCP circuit
functions in a similar manner to the MCP-IP2 card. For further information,
see Main Control Processor, page 8-8.
„ The Universal Gateway (UGW) provides the Coral IPx Office system with
the ability to connect to the IP World. The UGW circuit was previously part of
the Universal GateWay (UGW) card in previous systems. The UGW circuitry
includes the UGW processor, the connection to the MRC card, the UGW COM
port, the LAN ports, WAN port, and printer port. For further information, see
Internet Protocol Gateway, page 8-9.
„ The Group Controller (GC) contains the High-Level Data Link Control
(HDLC) bus interface circuitry, Pulse Code Modulation (PCM) bus interface
circuitry, clock circuitry to synchronize the peripheral section of the system,
Control Cards

and digital tone generators (dial, busy, ringing, ringback, DTMF, MFC, and
test). Additionally, the group controller contains circuitry to synchronize the
Coral peripheral clock to an external clock derived from a digital trunk
interface. The GC circuitry functions in a similar manner to the 4GC and
30GC cards in other Coral systems. For further information, see Group
8

4 Main Control Processor

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

The Main Control Processor (MCP) provides RS-232E KB0 programming and
maintenance interface, RS-232 UGW programming and maintenance interface, a
SAU connection, and an IMC8/16 interface. It integrates the main processor, memory
management circuitry, local bus interface, real-time clock, generic feature software
memory, and database memory.The MCP supervises overall system operation by
executing system-wide processes. These processes include port connection
management, feature management, generic feature software installation, feature
authorization, configuration database management, database backup and restoration,
program interface input/output and diagnostic testing.

Port Management

In order to manage port connections and feature operation, the main control processor
embedded circuit communicates through the MBP Office (backplane) card via the
HDLC buses. Communication is enabled with the local card processors on every
peripheral card both in the main and in the expansion units.
The main processor receives status messages from the card processors regarding port
activity. It determines the appropriate response based on the programming entries
contained in the system database. The main processor then instructs the appropriate
card processor what action to take with each port.

Memory Management
MCB Office Card Main Control Board

All system memory resides on the MCP embedded circuitry. RAM is located directly
on the MCB Office card. The MCB Office also acts as a mother card to the DBM-X
memory card and the MRC resources card. The DBM-X contains 2MB, 4MB, or 8 MB of
Static Random Access Memory (SRAM) expansion memory.
Flash memory, located on the IMC8/16 card, stores the generic feature software, which
determines the operation of the system. RAM, both on the MCB Office and on the
DBM-X expansion cards, stores the system configuration database, and is used as a run
memory for general purposes.
Database memory and real-time clock functions in the Coral system are protected
against power loss by a long-life lithium backup battery installed on the MCB Office.
A monitoring circuit on the card constantly measures the voltage level of the battery.
It signals the main processor when the remaining energy stored in the battery is
reduced to the level that it can no longer provide sufficient power to maintain the
8

memory circuitry.

8-8 Common Control Cards Coral IPx Office Installation Manual

 The generic feature software and feature authorization information is installed and
updated into the IMC8/16 using FMprog PC-utility. Similarly, the system database is
regularly backed up to, and may be transferred and restored from, an IMC8/16 card
housed in the IMC8/16 drive.

The Program Interface Facility

The PI (Program Interface) and CoralVIEW CVA/CVD provides a text-based facility
for reviewing and changing the system configuration and database. It enables the
performance and monitor of diagnostic routines. The PI can be accessed either via a
simple data terminal or by a personal computer.
The PI and CoralVIEW CVA/CVD/CVT can be accessed via an RS-232E data terminal
port (KB0) provided on the MCB Office front panel. See Figure 8-2.

5 Internet Protocol Gateway

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

The internet protocol gateway embedded circuit provides the Coral IPx Office system
with the ability to connect to the IP World. All Coral IP stations (FlexSet-IP 280S,
FlexIP SoftPhone, SIP) and external telephony gateways (Coral Teleport for analog
SLTs and Loop-Start/Ground-Start trunks) receive their Coral signalling from the
internet protocol gateway circuit.
The internet protocol gateway is the main Coral gateway to services offered on the
enterprise network. Voice calls maintained therein, although controlled by the Coral,
are carried out entirely on the network when both ports involved are IP ports, thereby
allowing heavy traffic configurations.
The internet protocol gateway circuit is a Coral integrated gateway for IP phones,

MCB Office Card Main Control Board

trunks and keysets (SLTs and trunks require a Coral Teleport). It provides the capacity
to drive up to 240 Coral IP ports, regardless of their physical location, and provides
full Coral services to these sets.
Certain Coral features require the intervention of the Media Resources Card (MRC).
The MRC is mounted on the MCB Office in piggyback fashion. It provides media
channels used to convert PCM calls to IP Packets and vice versa. Media channels are
also needed when one of the calling parties is not an IP host. No media channels are
needed for pure IP-to-IP connections (direct-connects). See MRC Card, page 8-27 for
further information.

1 Group Controller Circuit

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

The group controller embedded circuit serves as the communication link in the Coral
IPx Office system, between the MCB Office and the peripheral cards via the MBP
Office backplane.
The group controller circuit contains the High-Level Data Link Control (HDLC) bus
interface circuitry, Pulse Code Modulation (PCM) bus interface circuitry, clock
circuitry to synchronize the peripheral section of the system, and digital tone
generators (dial, busy, ringing, ringback, DTMF, MFC, and test). Additionally, the
group controller contains circuitry to synchronize the Coral peripheral clock to an
external clock derived from a digital trunk interface. The group controller circuit
supports two HDLC highways and sixteen PCM streams (including one stream
reserved for the MRC), and up to two expansion cages. It is capable of establishing a
maximum of 1000 time slots on its maximum peripheral shelf capacity. This matrix
allows for a constant frame delay operation mode.
The time slot distribution is described in Figure 8-4.

Voice Switching and Time Slot Configuration

The group controller supports up to two HDLC highways, 16 PCM streams, and up to
two expansion cages.
Each PCM stream includes 64 Time Slots. Each shelf unit (one or two expansion
cages) receives 384 Time Slots, divided into three groups of 128 Time Slots.
The Coral IPx Office supports 1024 PCM time slots. The shelf unit requires only 384
MCB Office Card Main Control Board

of the entire 1024 time slots. The remaining time slots are used for the main unit, the
tone generator, and the MRC. See Figure 8-4.

8-12 Common Control Cards Coral IPx Office Installation Manual

 Circuit Description
Clock Selection
The external clock synchronization selector monitors the two inputs 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 group controller to the digital trunk. In the absence of an external
clock source, the group controller 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.

PCM Streaming
Each PCM stream operates at a data rate of 4.096 bps. 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.

Using Time Slots

MCB Office Card Main Control Board

A call between two ports requires one transmit and one receive time slot on a single
peripheral highway. Therefore, the group controller is capable of establishing calls
between any 1000 time slots and any other 1000 time slots. This switching matrix
allows for a Constant Frame Delay operation mode.

2 Software Authorization Management

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

The MCB Office supervises the feature authorization using the SAU (Software
Authorization Unit) lock device. The SAU is a small, encapsulated device that is
plugged into a connector on the left side of the MCB Office. Figure 8-5 illustrates four
views of the SAU.
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 (MCB Office), enabling the system to function
properly.
The SAU provides the system identification number (i.e. a serial number). Each system
identification number is unique. In addition, the SAU stores a market identification
number, which indicates the general geographical area in which the Coral system is
installed. The system identification number is used to identify a particular Coral
system installation site.
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 that it remains attached to
the MCB Office 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:
MCB Office Card Main Control Board

„ The SAU serial number does not match the corresponding IMC8/16 SAU serial number.
„ The Coral generic version contained in the IMC8/16 is higher than is authorized by the
SAU.
„ An SAU device is removed from the MCB Office front panel.
Relevant system messages appear on the PI, warning that the system will not operate
without the proper SAU.

Replacing an MCB Office card necessitates removing the SAU from the old card and
installing it onto the replaced MCB Office card.

4 IMC8/16 Memory Card

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

The IMC8/16 is an integrated memory card with a 8 or 16 MB flash memory capacity.

It contains the generic software of the Coral and is used to store the system database.
See IMC8 and IMC16 Flash Cards, page 8-33 for details.
The IMC8/16 is used by the main control during run-time. The memory management
on the MCP-IPx allows part of the code to use portions of the IMC8/16 memory for
run-time. Therefore, the IMC8/16 card must not be removed from its drive during
system operation. If removed, the system will crash.

Do not Remove the IMC8/16 card form its drive during system operation. Removing the
IMC8 while the system is ON AIR will cause the system to shut down.

8 Lithium Battery Condition Testing

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

A new lithium battery can maintain power to the MCB Office memory circuitry and
real-time clock for approximately 90 days. The battery is not recharged by the system
power. Thus, if the battery has powered the memory and real-time clock for an
extended period and is almost depleted, the contents of the memory must be backed
up, and the battery must be replaced.
The battery voltage, tested under load, can be used to determine its state of charge.
Voltage measured across an unused 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
2.50 volts, the battery must be replaced.
For first time use, release the protective battery insulator. See Figure 8-8.

Replacing the Lithium Battery

In the following procedure, do not apply too much pressure to the battery clasp as this
could cause it to snap.
1. Carefully raise the battery clasp.

Do not use any metal tool to release or insert the battery. Doing so could result in a
short circuit and damage the battery.

2. Insert the new battery with the + (positive) symbol appearing on top.

MCB Office Card Main Control Board

Explosion and Environmental Hazards.
There is a 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 requirements specified by the battery
manufacturer and/or local regulatory agencies.

 URC2 Database Programming (U-RMI Office and U-MR Office cards)
The URC provides the features listed in Table 9-10. The URC in a Coral system has
considerable impact on the system database. Use the PI to verify that each of the
parameters detailed in this chapter is defined correctly. Refer to Program Interface
(PI) and Database Reference Manual for more details.

Maximum URC Resources

Each system resource circuit uses Coral times slots. The Coral enables a maximum of
120 time slots per URC2. Table 9-11 lists the time slots needed per circuit and enables
the technician to plan accordingly when configuring the URC configurations.
A maximum of 120 Time Slots is allowed per URC2 card. Therefore, the Full
Assembly is never used. Allocate your resources such that you use a maximum of 120
Time Slots. For example, increasing the number of 3-way circuits, forces you to
decrease one or more of the other resources.

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

The U-RMI Office and U-MR Office cards provide two (max: 6*) meet-me bridge
conference for 14 parties.

Separate authorization is required to allocate the CONF circuits supported

by the U-RMI Office and U-MR Office cards.
(max: *) The max. number is dependant on the number of URC time slots.

The Meet Me bridge manages conferences talk for up to 14/84 participants. Any
combination of trunks or stations can participate. The circuitry is completely digital.

Multi-Party Conference (CONF) Meet Me Conference Circuitry

During the conferencing session, each participant hears the voices of other
participants as their amplitude voices are added.
The Meet Me bridge allows the establishment of a conference call at an appointed hour
by dialing a special conference destination number.
The multi-party conference feature allows a conference of up 14/84 simultaneous
conversations in a conference mode.
The conference bridge is a Meet Me feature. Station users can dial the programmable
access code and/or transfer or be transferred to the conference call.
Access to the conference bridge may be defined through the Tenant feature.

2 Feature Descriptions
...................................................................................................

The Meet Me Bridge Conference Circuit (CONF) in the Coral IPx Office system
enables:
„ Group Call
„ Multiparty conference

URC Chained Meet Me Groups

The URC has 6 circuits that may be allocated as Conference ports. Each of these ports
can enable one conference of 14 participants. Alternatively, these conference ports can
be chained together internally by the URC, without using extra time slots, so that a
conference with a maximum of 84 participants can be created. The “chain” definition
is created via the PDB branch, see Special Port Facilities (Route: PDB,3), page 9-43.

84 participants requires URC Software Versions 2.xx or higher.

The conference number is displayed on the user’s keyset. However, different
Multi-Party Conference (CONF) Meet Me Conference Circuitry

members in the same chained conference may see different conference

numbers on their display.

URC Meet Me Conference Modes

The Meet-Me conference can be defined to operate in one of two different modes:
„ Summation:
Enables all conference participants to be heard simultaneously during the
conference.
„ Strongest Win:
Enables only the loudest speaker to be heard during the conference.
The technician is able to define a maximum number of participants when using the
Summation mode. When this maximum is exceeded, the system automatically
switches the conference to the Strongest Win mode (see PI Branch: CDB,11,2; CONF
MEMBERS, page 9-43 and CONF SWITCH DELAY, page 9-43 on URC Card DB - Meet Me

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

The U-RMI Office and U-MR Office cards provide 24 (max: 24*) port DTMF
receivers and decoders for touch-tone digits.

Separate authorization is required to allocate the DTMF circuits supported

by the U-RMI Office and U-MR Office cards.
(max: *) The max. number is dependant on the number of URC time slots.

The U-RMI Office and U-MR Office cards include the DTR circuits. The DTR
provides up to 24 circuits, which receive and decode Dual Tone Multi-Frequency
(DTMF) dialing tones. The DTR is required to support telephone station apparatus or
trunks that send DTMF tones to the Coral IPx Office system to activate system
features or select other ports.
DTMF signaling is commonly used by industry standard, single line telephone (SLT)
sets, as well as E&M tie trunks and Direct Inward Dialing (DID) central office trunks.
Loop-start and ground-start central office trunks, which are defined in the system
database as IRSS (Freedom) or DISA, require a DTR to be installed in the system.
The DTR uses industry standard DTMF receiver circuitry to decode DTMF dialing
tones. The audio side of each DTMF receiver circuit is directly coupled through a
CODEC to the Pulse Code Modulation (PCM) switching matrix of the Coral
IPx Office system. Decoded digital data is passed through the peripheral bus to the
DTMF Receiver (DTR)

system processor.

2 How many DTMF receiver circuits (DTRs) are required?

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

To provide adequate DTMF dialing Quality Of Service in the system the number of
DTMF receivers should match the anticipated traffic volume. The following table
provides the amount of DTR ports required for several different DTMF dialing port
sizes.

Number of DTMF Number of DTR

Dialing Ports Receiver Circuits

100 8

500 16

1000 24

This table assumes standard office traffic (medium traffic volume of 0.3Eg
per port). Higher traffic volumes should increase DTMF service accordingly.
Additional DTMF service should be used when features as FlexiCall, IRSS,
Freedom and DISA are used.

9.7 Dial Tone Detector (DTD)

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

The U-RMI Office and U-MR Office cards provide 16 (max: 32*) port DTD (Dial Tone
Detector) circuits for enhanced dialing, such as busy outside number auto-redial.

(max: *) The max. number is dependant on the number of URC time slots.

The DTD circuits are used to detect and identify standard call progress tones such as
dial tone, busy tone, reorder (fast busy) tone and ringback tone. The DTD is required
to support system features such as Automatic Called Number Redial (ACNR, also
called Scanner).
The DTD may also be utilized to force a station user to wait for a dial tone before
dialing to the central office. This increases the effectiveness of the toll restriction by
prohibiting users from dialing an unrestricted code before the central office is ready,
and then making a toll call when the dial tone is heard.
Each tone detection circuit of the DTD consists of a sophisticated audio noise level
detector. This circuit monitors audio signals and determines a constant or ambient
level, and then determines the presence of noise above ambient.
During operation, the system passes digitized voice signals from a port to be
monitored, through the Pulse Code Modulation (PCM) switching matrix to one of the Dial Tone Detector (DTD)
noise level detection circuits of the DTD. The presence of a call progress tone is
typically characterized by a sustained, non-fluctuating noise level.
The DTD then multiplies the periods that the tone is present and the periods of silence.
The durations of tone and silence are assembled to form a cadence (or rhythm pattern)
that is compared with an internal list of call progress tones and their associated
cadence. By matching the cadence of the monitored tone with the one contained in the
list, the DTD identifies the tone and reports the tone type via the peripheral bus to the
system processor.

9.8 Caller ID for SLT (iDSP)

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

The U-RMI Office and U-MR Office cards provide 16 (max: 32*) iDSP ports.

Separate authorization is required to allocate the iDSP circuits supported by

the U-RMI Office and U-MR Office cards.
(max: *) The max. number is dependant on the number of URC time slots.

The iDSP is required for displaying CID (Caller ID) for SLT users. The iDSP
application converts ASCII text information, received from the Coral main processor,
into FSK tone:
„ BellCore GR-30, or
„ ETSI 300-659-1 para. 6.1.1
The FSK tones are supplied for direct injection onto the Coral PCM highways. The
iDSP application provides up to 32 individual FSK tones simultaneously, each on a
different PCM channel and call.
The CID display feature for SLT requires Authorization for SLT-CID, and an FSK
compatible display unit installed on the SLT port.
The following information modulated in FSK is sent to an SLT interface by the iDSP
application, between the 1st and 2nd ring: Caller ID for SLT (iDSP)
„ Date,
„ Time,
„ Number (the last 10 digits),
„ Name (the first 15 characters); enabled through programming in the
configuration database.
The CID display unit detects this information and transforms it back into ASCII codes.
Up to 32 SLT sets can receive CID information simultaneously from a single URC

9.11 Remote Maintenance (Modem)

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

The U-RMI Office and RMI Office cards provide an auto-answer data modem. A full
duplex, asynchronous, ASCII modem, for remote programming the system database,
diagnostics and system maintenance, and/or for displaying various reports.
The modem operates at up to 56Kbps, using the ITU-T V.92 standard.
The modem answers an incoming call in Originate mode (no answer tone). To
establish a connection, the originating modem must initiate the call in answer mode
(by sending answer tone). This feature may be used as an added security measure to
protect the system database from intrusions.
0

2 Modem Jumpers - Enable/Disable

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

The U-RMI Office and RMI Office cards are equipped with jumper straps P5 and P6
(see Figure 9-3 on page 9-11) that enable and disable the modem. These jumpers,
when removed, disable the on-board modem, without affecting the other programming
interfaces. Thus, a local programming terminal or an external modem incorporating
more sophisticated security features may be operated while the modem is disabled.
The modem requires no external connections to function. The data side of the modem
circuitry directly accesses the peripheral data bus to communicate with the system
processor. The audio side of the modem circuitry directly accesses the switching Remote Maintenance (Modem)
matrix, is assigned a dial number in the system database and may answer incoming
calls in virtually the same manner as any other port in the system.
The modem can be configured to transmit or receive data. This is useful when
maintenance from a remote workstation is necessary. During normal system
operation, it is advisable to set the modem transmit and receive function to “Off” for
more secure system operation. Figure 9-11 displays the jumper settings for the
modem.

Background and Music-On-Hold (M1/M2)

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

The U-RMI Office, U-MR Office, RMI Office and MR Office cards provide the
following common system functions:
„ Two music inputs, one of which can be internal.
„ Music-on-hold interface (two ports).
„ Key telephone background music interface (two different sources)

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

Figure 9-12 and Figure 9-14 are simplified circuit diagrams of the two Music
Interfaces. The external music (M1,M2) interfaces are electrically identical. Audio
signals to the system are passed through the audio coupling transformer to the
interface. A direct current (DC) blocking capacitor protects the secondary winding of

Music Background and Music-On-Hold (M1/M2)

the audio coupling transformer from conducting DC energy. As a music input the
circuit operates as an input only, and so it can be used to play but not record music.

M1 Internal/External music
Internal music (M1) is available in all cards. The selection between the internal or
external source is accomplished by P2 jumper located on the U-RMI Office, U-MR
Office, RMI Office and MR Office cards. See Figure 9-13. Table 9-20 defines the
position of P2 for the music selection.

M2/P Paging/External music

External music (M2/P) connector can be used as voice paging output. The selection
between the external music source or voice paging output is accomplished by P3
jumper located on the U-RMI Office, U-MR Office, RMI Office and MR Office cards.

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

The U-RMI Office, U-MR Office, RMI Office and MR Office cards provide one
external paging interface (public address, one port). Station users can access an
external voice paging system connected to the Coral IPx Office by dialing access code.

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

Figure 9-17 is a simplified circuit diagram of the Paging Interfaces and the relay
contacts.
Each U-RMI Office, U-MR Office, RMI Office or MR Office card provides one paging

Voice Paging (Public Address) and Relay-1 Public Address

output: the external voice paging port operates by using both the relay circuit (RLY1)
and the PAGE circuit. The PAGE circuit is used for public address.
The External Paging (PAGE) Interface is electrically identical to the Music interfaces.
Audio signals from the system are passed through the audio coupling transformer to
the interface. A direct current (DC) blocking capacitor protects the secondary winding
of the audio coupling transformer from conducting DC energy. As a music input the
circuit operates as an input only, and so it can be used to play but not record music.
The relay provides form A (single pole, single throw and normally open) contacts for
activating external circuitry and devices. Contacts RLY1 are designated to operate in
conjunction with audio interface PAGE for external paging applications. Care must be
taken not to exceed the contact ratings listed in the specifications.

M2/P Paging/External music

Page (M2/P) connector can be used as a music source. The selection between the
music source or voice paging output is accomplished by P3 jumper located on the
U-RMI Office, U-MR Office, RMI Office and MR Office cards. See Figure 9-18.
Table 9-22 defines the position of P3 for the music selection.

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

Incoming trunk calls may be directed to activate a relay contact at certain times of the
day (typically after normal business hours). The relay contact sounds a tone over a
paging or public address system, or operate a mechanical bell. Upon hearing the tone
or bell, the trunk is then answered by dialing a specific feature code at any station
allowed to answer calls.
Figure 9-27 and Figure 9-28 illustrate connections to a contact operated tone signal
and to a mechanical bell. Note that due to electrical limitations, the contact may not
be used to switch loads requiring high voltage or high current. See Relay Contacts on
page 9-99, for complete specifications. To operate a highly inductive load such as a
mechanical bell, the relay should operate an external, AC powered or non-inductive
relay with an appropriately rated contact, which in turn operates the mechanical bell.

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

The U-RMI Office, U-MR Office, RMI Office and MR Office cards incorporate two
relay contacts (1-2 and 3-4) for two of the following three features:
„ External voice paging (PAGE). Described on page 9-77.
„ Universal Night Answer (UNA) Central Bell. Described on page 9-85.
„ Dial operated accessory/alarm (RELAY). Described on page 9-91.
The applications described in the sections above describe several examples of the
control of external devices through relay contacts on the U-RMI Office, U-MR Office,
RMI Office or MR Office cards. A limited description of most of the external devices
is listed herein. In each application, however, several important factors should be
considered.
The relays provide form A (single pole, single throw, normally open, or SPST-NO)
contacts for activating external circuitry and devices. Operation of the relays is
determined by the system database.
„ Contacts RLY1 are designated to operate in conjunction with audio interface
M2/P for external paging applications.

Relay Contacts RLY1, RLY2, RLY3

„ Contacts RLY2 are designated as a UNA Bell destination.
„ Contacts RLY3 are also designated for use as either a major or minor system
alarm signal, or an auxiliary dial-operated relay contact.
The relay contacts provided on the U-RMI Office, U-MR Office, RMI Office and
MR Office cards have specific electrical limitations. See Specifications - Relays below.
Do not exceed these limitations. In addition, the type of load the relay contact operates
can have a great significance.
Ideally, the contact should operate a low voltage, low current, non-inductive load such
as a light bulb or solid state device. When the voltage or current increases, or when an
inductive load such as a relay coil or solenoid is connected, the likelihood of arching
across the contact increases. Contact arching occurs while the contact is opening and
9

burns away the precious metal surface, increasing the chance of the contact being

Shared Service Cards 9-99

 "welded" closed or failing completely. Arching also generates high frequency energy
that may be coupled to any one of the data busses of the Coral IPx Office, causing
unreliable or unpredictable system behavior.
If the contact is to operate a relay or solenoid, use an alternating current (AC) operated
device and an AC power source, if at all possible. AC operated inductive loads
produce much lower arc levels than direct current (DC) operated loads.
If the contact must operate a DC powered inductive load, the contact must be
adequately protected by arc suppression devices. Figure 9-36 illustrates the use of a
common rectifier diode as a simple arc suppression device. The diode is normally
reverse biased (not conducting) with the cathode (top side in the drawing) connected
to the positive side of the power source.

When the inductive load is powered, a magnetic field is created around the coil
windings. When power is removed, the magnetic field quickly deteriorates, producing
a reverse polarity voltage (counter EMF) across the windings. This reverse polarity
voltage is typically many times the voltage which originally powered the coil,
providing enough potential to arc across the open relay contacts.
By placing the diode in the circuit, the reverse polarity current is conducted by the
diode, shunting the energy around the contacts. A rectifier rated at 1.0 ampere forward
current (1.0A IF) and a peak inverse (reverse) voltage of at least 250 volts (250V, PIV,
PRV, or VRM) should be sufficient in most cases.

2 Configuring the Relay Contacts Jumper

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

Figure 9-37 is a simplified circuit diagram of the two relay contacts.

The relays provide form A (single pole, single throw and normally open) contacts for
activating external circuitry and devices. Operation of the relays is determined by the
system database.
Only two of the three relays functions (RLY1, RLY2, RLY3) can be selected. The
selection is accomplished by P4 straps located on the U-RMI Office, RMI Office,
U-MR Office and MR Office cards (see Figure 9-37). Table 9-27 defines the
position of the P4 straps for the relays selection.

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

The Coral IPx Office system divides peripheral interface functions among several
different station and trunk card types. Each card contains 4, 8, 16, 20, or 24 circuits.
Some analog trunk peripheral cards support power fail transfer, as described on Power
Fail (PF) Transfer Circuits, page 5-15.
Coral IPx Office systems convention suggests that peripheral interface cards are
installed in specific card slots, as described in Table 10-4 on page 10-19.
Each Peripheral card is described in detail in the Coral Service and Peripheral Cards
Installation Manual.
0

2 Card Handling Procedures

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

Each of the Coral IPx Office cards contains circuitry sensitive to electrostatic
discharge (ESD). Failure to observe safe handling procedures for static-sensitive
circuitry may result in permanent damage to a card.
An anti-static wrist strap, connected to the ground terminal pole and tightened with the
wing nut should be worn while inserting, removing, or handling any card in the
system. Each card is shipped inside an anti-static plastic bag. Cards should be kept in
this bag whenever handling is not required.
Peripheral Card Installation

Before removing a peripheral card, disconnect the I/O connectors.

After a peripheral card is removed, wait for at least 2 seconds before

re-inserting the card. If not, the card will not function properly.

3 General Installation Procedure

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

Peripheral card installation and initialization are done through automatic identification
by the hardware application called "Plug and Play" (plug in and start working). All the
technician has to do is to install the card into the required slot and connect its
respective I/O cable. The MCB Office card will identify the peripheral card, define it
for the system and display all details on the PI screen. The PI Card List branch (Route:
CLIS), Snap Mode, shows details of every new peripheral card that is installed or
removed. There is a short delay between installation/removal of the card and PI screen
display.
All peripheral cards may be inserted into a card slot only if the card slot has not been
previously initialized by another card type. Before installing the card into a card slot
that has been initialized by another card type, the previous card name must be cleared
first.
To clear an initialized card slot:
1. Select the Card List branch (Route: CLIS) in the system database.
2. If the I_TYPE for the card slot shows a card type other than the card currently
installed, enter NO_CARD to clear the slot. Refer to Program Interface and
Database Reference Manual - Chapter 6, for further details.
0

4 Diagnostic LED Indication

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

Each plug-in Office service and peripheral card is equipped with one or two red
diagnostic indication LEDs on the front side, near the right side of the card1. These
LEDs can assume one of three states of illumination: OFF, ON, or FLASHING. The
illumination state of the LED indicates the card's operating condition. Table 10-1 lists
the indication provided by each of the three LED states.
Peripheral Card Installation

During normal operation, the card diagnostic LED should be extinguished. However,
the LED routinely illuminates steadily whenever power is first applied to the system,
the entire system is initializing, or the card is first inserted into a card slot. The LED
remains illuminated steadily until the card receives a card database from the system.

1. In the U-RMI Office and U-MR Office card a second LED is located in the middle of the
10

card.
In the 4S8F Office, 4S16F Office, 8S8F Office and 8S16F Office cards a second LED is
located in the right side of the card.

10-2 Peripheral Cards Coral IPx Office Installation Manual

 LED Constantly Lit
If the LED stays lit for more than two or three minutes, a problem may exist within the
card. The most likely problem is a conflict with the system database, although it also
may be an actual malfunction of the card circuitry.

Table 10-1 Card LED State Indication

Diagnostic LED
Indications Extinguished Off No problem with the card, it is operating OK.
Steadily lit - ON Card has not received a card database from system.
Flashing Diagnostic test failed by circuitry on card.

The system database will prevent a card from initializing:

„ When the card is inserted into a card slot that has been initialized with another
card type.
Check the Card List branch (Route: CLIS) in the database, to determine
whether the card slot has been previously initialized with a different card type.
If the STATUS field shows CARD REPLACED, and the I_TYPE for the card
slot shows a different card type, enter NO_CARD to clear the slot.
„ There are insufficient system resources allocated in the System Sizes
Definition to support the new card. The STATUS field in the Card List branch
(Route: CLIS) shows NO RESOURCES. Check the Sizes branch (Route: SIZ)
in the database to determine the maximum number of ports of the type
provided by the problematic card, and then determine how many of these ports
are already installed. If the additional ports provided by the new card exceed
the maximum number allocated in Sizes, the card cannot initialize.
This situation can be rectified only through restructuring the memory
allocation of the system. Initializing the database and reprogramming the
system restructures the memory allocation.

LED Flashing Peripheral Card Installation

The Coral IPx Office system continuously runs diagnostic routines to monitor the
performance and integrity of its database and circuitry. When the circuitry on a
particular card fails to perform as expected the system instructs the card to flash its
diagnostic LED. If, on a subsequent execution of the same routine that reported a
failure, the circuitry passes the test, the card is instructed to extinguish the LED.
Occasionally, circuitry may fail a diagnostic test, even though it is not truly defective.
If a card diagnostic LED is observed flashing but no problem is apparent, wait 60
10

minutes and check the card again. If the LED is no longer flashing, the test failure was

Coral IPx Office Installation Manual Peripheral Cards 10-3

 probably insignificant. If the flashing continues however, the card is likely to be
malfunctioning, even if no problem can be identified.

 10.3 Digital Trunk Synchronization

1 Slave Clock Mode Operation

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

The Coral IPx Office system is capable of operating in either master clock mode or
slave clock mode. The selection between modes is made via the PI software.

How The System Derives The External Clock Signal

The Coral IPx Office uses digital trunk interface cards to synchronize its internal clock
with the PSTN clock or with another switching system clock. When operating in
slave-clock mode, the data stream transferred on the digital trunk is fed into the
MCB Office (Main Control Board), incorporating the external clock rate into the
Coral IPx Office internal clock.
To allow the clock signal to be fed into the Coral IPx Office internal clock, the ESIM
and the digital trunk interface cards are properly strapped to accept those signals.
Two synchronization sources can be defined for a system. One serves as the primary
source and the other serves as a secondary synchronization signal source.
The following digital trunk cards can retrieve synchronization signals in the Coral
IPx Office main unit: UDT Office (PRI-23 or T1), 30T Office, PRI-30 Office, and
4TBR Office.

Digital Trunk Synchronization

The following digital trunk cards can retrieve synchronization signals in the Coral
IPx 500X expansion cages: UDTipx (PRI-23 or T1), 30Tipx, PRI-23ipx, PRI-30ipx,
4TBRipx and 8TBRipx.
More Coral FlexiCom 300,400,5000,6000 and IPx 800,3000,4000 digital trunk cards
(UDT, 30T, T1, PRI-23, PRI-30, 4TBR, 8TBR) are available for synchronization
purposes through the Coral IPx 800X expansion cages.

2 Synchronization Slots in the Main and Expansion Cages

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

Two slots, located in the Coral IPx Office main unit, are set to accept the digital trunk
cards: slot # 8-9 and slot # 10-11. Each card can be installed into either slot. See
Figure 10-3 below.

Synchronization Slot Selection

Any combination of primary and secondary synchronization sources, either in the
main unit or in the expansion cage is valid.
The hardware selection between the Coral IPx Office unit and the expansion cages
synchronization slots is determined by:
„ In the Coral IPx Office main unit, jumper settings on the ESIM Office and on
the digital trunk cards.
„ In the expansion cages, jumper settings on the backplane card.
In addition, a software selection must take place. The system must be notified, via the
PI facility, of the synchronization cards shelf/slot location. See Choosing the Best
Synchronization Source, page 10-12.

Conditions for Slave Clock Mode Operation

The following conditions are necessary for the Coral IPx Office to retrieve external
clock signals:
„ The jumpers must be strapped accordingly on the digital trunk cards and on
the ESIM Office card.
„ The digital trunk synchronization cards must be installed in the
Digital Trunk Synchronization

synchronization slots of the expansion cages (IPx 500X and IPx 800X).
„ The PI parameters must be properly set.

System Switch from Slave Clock Mode to Master Clock Mode

When a digital trunk card is initialized in the appropriate slot, the jumpers properly
set, and the shelf/slot combination has been entered as a primary external clock source,
the system determines if the digital trunk card in the indicated position is properly
synchronized with the network. If the system is functioning properly, it locks onto the
10

primary external clock source.

10-10 Peripheral Cards Coral IPx Office Installation Manual

 If the primary digital trunk card issues a LOS or Red alarm, and a secondary external
clock source is defined, the system determines whether the secondary digital trunk
card is functioning properly. If it is, the system then locks onto the secondary external
clock source.
If no secondary clock source is defined, or the secondary clock is also in LOS or Red
alarm, the Coral IPx Office system uses its internal clock source, and the system free
runs.

 BRI Lines for Synchronization

1) BRI lines used for synchronization must be defined in the PI (Route:

DTDB, 4) SYNC - YES. See PI Manual Chapter 26 - ISDN for more
information.
2) It is not recommended to use BRI lines defined as
PERMANENTLY_ACTIVE_CHANNEL - NO as synchronization sources.

It is not recommended to use a PRI card with IPAT IC (hardware issue 4) chip
as a synchronization source.

Order of Preference
The possible digital trunk synchronization sources are listed in order of preference:

1. PRI or T1/E1 card (all types) connected to PSTN type stratum #3 - TANDEM
switch (North America only).
2. PRI or T1/E1 card (all types) connected to PSTN type stratum # 4 (End office).
3. PRI or T1/E1 card (all types) connected to a private network. There are three
possibilities listed in order of preference.
a. The network is synchronized on PSTN stratum #4 (or less).
b. The private network contains a stable internal clock.
c. The private network is synchronized to the Coral - do not use for

4CID Office The 4CID Office is installed on the 4T Office card in Coral IPx Office
systems. See Figure 10-23 on page 10-43.
The 4CID Office card is used for detecting CID (Caller ID) information,
modulated in FSK (Frequency Shift Keying), sent from the PSTN over
Loop-Start trunks.
The 4CID Office card includes 4 circuit FSK tone receiver and decoder.
The card converts FSK tone:
„ BellCore GR-30, or
„ ETSI 300-659-1 para. 6.1.1
into ASCII text information. The ASCII information is sent to the Coral
IPx Office main processor for CID displaying on FlexSet, SLT (see
4/8/20S Office and URC above) and for SMDR, CLA, APA, etc.
The CID feature for analog Loop-Start trunk requires Authorization for
Caller ID. Each trunk can be individually enabled through programming
in the configuration database.

 11.1 NTU Office Card Description

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

This section describes the networking functions of the Coral IPx Office system. For a
description on how to install the networking card and components, see NTU Office Card
Installation, page 11-9.
Coral IPx Office offers a complete integration of traditional telephony and VoIP
networking abilities. Connection to the WAN is facilitated without installing an
additional UGW card or router. The Coral IPx Office includes UGW circuitry
embedded on the MCB Office control card as well as the NTU Office (Network Unit)
card that is installed within the system at specific customer request. The NTU card
functions as a router, enabling direct connection to the WAN. A WiFi card can be
installed upon the NTU card supplied at specific customer request. In addition, it also
enables direct connection to a printer via a USB port.
0

2 System Operation without an NTU Office Card

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

The Coral IPx Office system enables seamless connection to the digital and IP world
with or without an NTU Office card. Without an NTU Office card, the Coral IPx
Office can connect to the WAN only after an external, customer-supplied router has
been connected. See Figure 11-1.
NTU Office Card Description
Media Stream from the Digital World to the LAN and WAN
PCM streams are directed from the Coral to the MRC, which converts the PCM
streams into RTP packets. See MRC Card, page 8-27 for more information. The RTP
packets are directed through the UGW internal switch. The switches direct the packets
to LAN ports 1-8. The DHCP server provides the dynamic IP address to the devices,
enabling connection to the endpoints on the LAN. An external, customer-supplied
router directs the packets to their destination over the WAN.
11

Coral IPx Office Installation Manual System Networking 11-3

 Media Stream from the LAN and WAN to the Digital World
Packets are directed from a customer-supplied router from the WAN into one of the
LAN ports. The packets are directed from the LAN into one of the LAN ports.

If a network card is not installed in the system, the WAN port can function as
an additional LAN port when a cable is connected between two RJ-45
connectors on the surface of the MCB Office card. For more information, see
Connecting to the Network without an NTU Office Card, page 11-21.

LAN and WAN packets are directed from ports 1-8 (and potentially from the WAN
port as well) through the UGW internal switch. The packets are then directed into the
MRC, which converts the RTP packets into PCM streams and directs them to the
Coral.

3 System Operation with an NTU Office Card

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

The Coral IPx Office system enables seamless integration between the digital and IP
world with or without an NTU Office card. With an NTU Office card, the Coral IPx
Office can connect to the WAN directly from the WAN port without any additional
external router. See Figure 11-2.

Media Stream from the Digital World to the LAN and WAN
PCM streams are directed from the Coral to the MRC, which converts the PCM
streams into RTP packets. See MRC Card, page 8-27, for more information.
RTP packets designated for the LAN are directed through the UGW internal switch.
The UGW switch directs the media stream to LAN ports 1-8. The dynamic IP
addresses are either provided by the NTU Office card or the DHCP server, enabling
connection to the endpoints on the LAN.
RTP packets designated for the WAN are directed to the NTU Office card, which then
directs them through the external WAN port on the front panel to their destination on
the WAN.

Media Stream from the LAN and WAN to the Digital World
WAN Packets are directed from the WAN port directly to the NTU Office card. The
NTU Office card redirects the RTP packets to the MRC card, where they are translated
into PCM streams. Finally, the PCM streams are directed to the digital network.
LAN packets are directed from the LAN ports 1-8 through the internal UGW switch,
which is embedded on the MCB Office card. The packets are then directed into the
MRC, which converts the RTP packets into PCM streams. Finally, the PCM streams
are directed to the digital network.
