1 Basic Information

General
In the Marconi Access Network, the Remote Network Unit (RNU) is used
to connect 64 kbit/s and 2 Mbit/s subscribers via a Point-to-Multipoint
(PMP) architecture.
The connection of the Remote Network Unit to the FlexPlex MSV5
(CDN) can be set up via a PMP radio link or an electrical 2 Mbit/s
interface (G.703).
Both V5 signalling information and OAM information is transmitted in the
CC channel between the FlexPlex MSV5 (CDN) and RNU. The CC
channel occupies time slot 16 of the 2 Mbit/s signal.

MDMS and its RNUs

The RNU30-R, RNU8-R and RNU4M-8C provide the subscriber
interfaces as well as the interfaces for radio access.
The RNU 30-E, RNU8-E and RNU8C provide only one
2 Mbit/s interface for setting up the connection to FlexPlex MSV5 (CDN).
In case of long distances, the Point-to-Multipoint architecture can be used
by connecting the appropriate equipment for a radio connection.
The difference between the RNU4M-8C and RNU8C hardware is that the
RNU4M-8C is equipped with two 2 Mbit/s interfaces. One of the two
interfaces is connected to the 8C component of the RNU. Only this
section is relevant for the LMT software.
The LMT software "sees" no difference between the RNU8C and
RNU4M-8C.
The following diagram shows the RNUs in the Marconi Digital Multipoint
System (MDMS).

Components of a network element
Within a network, the RNU is regarded as a network element (NE). A
network element is usually composed of several units which can be
individually addressed. A general overview is given in the following
diagram:

The internal subaddressing within the network element is performed via

• Functional units:
The subdivision into functional units is based on the
functional structure of the network element (see block
diagram).
• Functional groups:
A functional group contains all identical functional units of an
NE. All functional units belonging to the same functional
group fulfill the same application functions.

System configuration
A network element (NE) is composed of different types of functional units
(FE), e.g. input port, clock supply, multiplex function etc.. Each NE can
contain several functional units of the same type. Similar FEs are
combined to form functional groups.
In order to be able to manage an NE by means of the Operations System,
the latter must know, which FEs are really available. This information is
supplied by the "System configuration" application function.
In the System equipment function, the "FG equipment" is displayed under
subaddress 00:00 (FG=00, FE=00). Here the system indicates the FEs
available in the FGs of the network element.
For each FG, there is a partial equipment. This "FE equipment" is
signalled for each FG in an own telegram, subaddress FG:00 (FG =
Functional group no., FE=00) being used for this purpose.
Processing rules
After a reset of the NE or SISA0, the SISA0 determines the functional
units (FEs) available. This information is then used to initialize the FEs
contained in each FG as well as the FGs included in the NE.
In the event of modifications of the FE configuration (e.g. when a module
is mounted or removed), a "System configuration" spontaneous message
(event) containing the new equipping status is sent to the OS.
Modifications of the FG equipment are not signalled immediately.

LMT RNU30/8 User Manual • 1 Basic Information 1-3

 Equipment with modules
The equipment with modules indicates the hardware components of a
network element. In the SISA specification, these components are
referred to as "Modules".
An NE can be composed of a maximum of 254 individual modules. Each
module has its own, unambiguous module address within the NE.

1-4 LMT RNU30/8 User Manual • 1 Basic Information

Information model - RNU functional model
RNUs with an own radio access are composed of two network elements,
i.e. the Network Unit (NU) and the RRS (Remote Radio Station). In the
SISA specification, these network elements are described by means of a
functional model.
The network element functions are represented by so-called functional
groups (FG).
A functional model allows a hardware-independent view of the NE.
A higher-order Network Management System "sees" the NE from this
view. The Operator Terminal program also works on the basis of this
view. By entering the appropriate command, the hardware view (modules)
can be switched over to the SISA view (SISA mode).
The NU network element is configured by means of the LMT. For the
RRS network element, the SECO (Service Controller) or INCO
(Installation Controller ) are used for configuration.
The functions of the network elements are represented by so-called
functional groups (FG). The FG no. is defined by a the corresponding
SISA specification.
The LMT and the higher-order Network Management System, e.g. Open
NSÜ, "see" the NE from this view.

NU functional model
The following equipment class and equipment version have been defined
for the NU network element:
Equipment class: 11h
Equipment version: 04h
The following diagram shows the functional model of the NU network
element.

Login
A logic connection to the NE can be set up in the following ways:
• Local connection to the NE
• Remote connection to the NE via the SISA address (VMP01)

Local login
In case of a local link, the LMT directly communicates with the NE to
which it is physically connected. In this case, it is not necessary to enter
any addresses.

Remote login via the SISA address

In SISA networks you can also log in via the VMP01 address.
The address "0e" is the address (joker address) of the local NE, to which
the PC is connected. If you want to address another NE, you must enter
the complete SISA address referred to the connection point.
Example: LMT connected to MSV5, RNU with ID 101 => 0a/101e.

Executing the login process

1. Start up the Operator Terminal program.

2. Click the button.

Performance data
The digital signals pass various SDH/PDH sections (e.g. the Multiplex
Section). For each section, performance measuring points are defined at
which the signal can be checked for its bit error ratio.
Then the NE calculates the performance data for the corresponding test
interval. The performance data are stored in the NE in 15-min. and 24-hr.
records.
After expiry of a test interval, the performance data can be requested. In
addition, you can request the performance data which have been
calculated at a certain time.
The Operator Terminal permits the following functions to be executed:
• Configuring performance measuring points,
• Requesting performance data,
• Saving performance data to the database.

Configuring performance measuring points

If you want to determine the performance data of a certain section, you
have to configure the corresponding performance measuring points, i.e.
you determine the number of records to be stored for each measuring
point in the NE.
Number of configurable performance measuring points
The number of performance measuring points configurable depends on
the number of 15-min. and 24-hr. records you want to store for each
performance measuring point (PMP) in the NE (parameterization). In
case of a full parameterization, i.e. 100 x 15-min. and 30 x 24-hr. intervals
per PMP, a total number of 256 PMPs can be configured.
The maximum number of configurable performance measuring points can
be increased by decreasing the storage depth (e.g. 100 x 15-min. and
only two 24-hr. records).
The NE sends a message to the Operator Terminal as soon as the
maximum permissible number of PMPs is exceeded.
The NE can determine performance data at the following measuring
points:
• ISDN Access BA with SU Uk0 BA.
• EPP2 D1

LMT RNU30/8 User Manual • 3 General System Functions 3-9

 1. Open the "Signal Structure" window.

6. In the "Memory depth" box, enter the number of 15-min. and 24-hr.
records you want to store in the NE.
7. Click the <Send selected element> button.
From now on the NE determines the data for this measuring point. For
the 15-min. interval this means that the first record will not be available
before expiry of this interval (15 minutes).
Note: Since the NE works with a fixed 15-min. time pattern (e.g. 15.00,
15.15, 15.30 .....), the interval can be up to 15 min. longer depending on
the actual moment of activation of the monitoring function.

Introduction
In the RNU Remote Network Unit, only 64 kbit/s switching matrix
connections are routed via the BPX switching matrix.
The RNU is connected to the FlexPlex MSV5 system (CDN) via a 2 Mbit/s
transmission link.
The 64 kbit/s data of the subscriber interfaces are mapped into a 2 Mbit/s
signal.
The 2 Mbit/s signal is then routed via a radio link to the base station from
where it is passed on to FlexPlex MSV5 (CDN).
In the RNU30-E or RNU8-E and RNU8-C application, the 2 Mbit/s signal
is routed via an electrical 2 Mbit/s interface (G.703) to the FlexPlex MSV5
multiplexer. RNU8C can also be connected via a radio link (in conjunction
with RNU2MxN).
If the distance between the RNUs and FlexPlex MSV5 is too long, the
electrical connection cannot be set up. In this case, the 2 Mbit/s signal is
returned to the 2 Mbit/s input of an RNU equipped with a radio section
(e.g. RNU2MxN or RNU4M-8C).
The RNU4M-8C is equipped with its own radio section, i.e. the connection
to FlexPlexMSV5 is set up via a radio link.
The signalling information and OAM data exchanged between the RNU
and CDN are transmitted in time slot 16 of the 2 Mbit/s signal.

64 kbit/s connections
In case of bidirectional 64 kbit/s connections, a distinction is made
between
• 64 kbit/s leased line connections
• 64 kbit/s connections with V5 switching software
Leased line connections
Leased lines (LL) are connections with a fixed assignment between a
subscriber and channel (64 kbit/s).
These connections are routed flexibly via the switching matrix.
The subscriber has a certain channel always at his disposal.

Connections with V5 switching software

In case of connections set up by means of the V5 switching software,
there is no fixed assignment between a subscriber port and a certain
channel of the 2 Mbit/s signal.
If the subscriber wants to set up a connection, he is assigned a time slot
of the 2 Mbit/s signal by the V5 management.
The D0 connection attributes of the subscriber port are set to "Virtual" (V5
exchange software).
In the 2 Mbit/s signal, a sufficient number of time slots must also be set to
"Virtual".

Nx64 kbit/s connections with SU-N64k
The SU-N64k module permits the transmission of data signals at n x 64
kbit/s, with n = 1 to 30.
The transmission of control line signals between the data terminals is
possible. However, for this purpose, an own 64 kbit/s channel must be
used. The maximum n of the data channel is thus reduced by 1.

1. In the "Digital System Settings" form, adjust the “Synchronous nx64“

mode and the desired bit rate.
2. Call up the "Cross-Connections" window.

3. Choose the button or select the "BPX" command from the

Special features regarding the configuration of

64 kbit/s time slots
In order to ensure time slot integrity during transmission, the following
special features must be taken into account:
• The time slots (n+s) assigned in the RNU to an SU-nx64k
must be configured in a closed LL bundle in the IPMB64/2.
• In the IPMB64/2, the LL bundles must start only in the
defined time slots.

 SU-nx64k time slot assignment in the IPMB64/2

In case of the LL time slot assignment of the IPMB64/2 for configuring an

SU-nx64k, please note the following:
In the 2 Mbit/s signal time slots marked with x, LL bundles (nx64k) may
be configured only up to time slot 31 to ensure that time slot integrity is
not violated.
All other time slots are not appropriate for LL bundles to start, but may be
used by them.
When configuring time slots in the LL bundle, please ensure that the
assignment of SU-nx64k to the correct card slot and the associated table
is taken into account.
Example 1:
An SU-nx64k module (n=6) is mounted in card slot 101 (slot 1)
(6x64k=385 kbit/s). The bundle starts in time slot 2 and reaches into the
time slots not marked with x.
Example 2:
An SU-nx64k module (n=8) is mounted in card slot 103 (slot 5)
(8x64k=512 kbit/s). The bundle starts in time slot 12 and does not reach
into the time slots not marked with x. The CC channel, i.e. time slot 16, is
not used. A control channel s has been configured.
Both examples show permissible configurations.

Nx64k configuration
The SU-N64k module is used for data transmission at nx64kbit/s with n =
1 to 30 (with and without control lines) and for asynchronous data
transmission up to 19.2 kbit/s with 64 kbit/s oversampling.
Between the card slot equipped in the RNU30 subrack and the
configurable nx64kbit/s channels there is a dependency which is
explained in the following section.

Special features regarding the equipment of

RNU30 with SU-N64k modules

Adjacent card slots are depicted in a combined manner.

RNU30 equipping combinations with SU-nx64k

Each RNU30 can transmit up to 30 x 64 channels in the network
direction. Groups of two adjacent card slots (101/102, 207/208, 103/104
and 209/210) are accessing the same internal sub-bus, which is part of
the complete bus.
This results in the restrictions indicated in the table below regarding the
maximum number of time slots n>14 as a function of the RNU30 card slot
equipment in pairs.
As long as n is lower than or equals 14 for SU-nx64k modules possibly
mounted, any SU configuration is possible.

5-8 LMT RNU30/8 User Manual • 5 Configuring Subscribers

 If in one of the SU-nx64k modules mounted, n exceeds 14, the following

s Control signals in a separate 64 kbit/s channel (if s is
transmitted, nmax is reduced by 1)
Important:
• On card slots 102, 104, 208 and 210, a maximum of 14 time
slots can be configured for SU-nx64k (irrespective of the
adjacent card slot).
• The permissible equipping combinations and the maximum
configurable number n+s can be monitored by the
Configuration Management function. Wrong combinations
will be ignored.
• A maximum of 30 x 64 kbit/s channels can be occupied in the
IPMB64/2.
• For n > 16, the adjacent card slot must remain empty.

Adjusting the operating mode

The operating mode (synchronous n x 64k, oversampling) must be
adjusted in the "Digital System Settings" form.
The following operating modes are possible:
• Synchronous nx64k
• Oversampling (64 kbit/s)

LMT RNU30/8 User Manual • 5 Configuring Subscribers 5-9

 Adjusting the data rate and sampling frequency
The "Digital System Settings" form permits the data rate to be adjusted
for the "Synchronous nx64k" mode and the sampling frequency for the
"Oversampling" mode.
Adjusting the data rate
After selection of the "Synchronous nx64k" mode, you must still adjust
the desired data rate in the "Data rate/Sampling rate" box.
The data rate can be set from 64 kbit/s to 1920 kbit/s in steps of 64 kbit/s
(n x64 kbit/s with n = 1 to 30).
For transmitting control line information between data terminals, an own
64 kbit/s channel must be used for each nx64 kbit/s data channel.
The maximum "n" factor per nx64 kbit/s data channel is thus reduced by
1.
Control line information is transmitted in channel n+1.

Adjusting the sampling rate

In the "Oversampling" mode, you must enter "64 kHz" in the "Data
rate/Sampling rate" box.

Adjusting the interface type

The SU-N64k module is available with V.35 or V.11 interfaces.
The adjustment of the interface variant used is made in the "Interface
type" box of the "Digital Transmission Features" form.

Continuous logic state monitoring

In the "Continuous Logic State Monitoring – Loops" form, you make the
entries necessary for monitoring the traffic signal at Din for continuous "1"
or continuous "0".
The following configurations are possible:
• No monitoring of traffic data for continuous logic states
• Monitoring of traffic data for continuous "0"
• Monitoring of traffic data for continuous "1"
• Monitoring of traffic data for continuous "0" and "1"

 Test loops

For service purposes, two test loops can be switched on the SU-N64k
module:
• Loop to subscriber side (LOOP2)
• Loop on system side (IOM bus)

LOOP2 (local loop)

Loop 2 (in compliance with ITU-T Rec.V.54) has the following features:
• Loopback from receive to transmit data, i.e.
with V.11: R --> T,
with V.35: RXD (104) --> TXD (103)
• Outgoing signal binary "1"
- V.11: R,
- V.35: RXD (104)
• Incoming signal interrupted
- V.11: T,
- V.35: TXD (103)
• Internal loopback from DCD (109) --> RTS (105) with V.35
• Incoming signal RTS (105) interrupted
• Outgoing signal DCD (109) OFF
• Outgoing signal CTS (106) OFF
• Outgoing signal DSR (107) OFF

IOM loop (external loop)

With the IOM loop, the DTE --> DFE signal is looped back to the system
side.

 Control line settings
In case of control line transmission, "n max" available for traffic data
transmission is reduced by 1 for each nx64 kbit/s data channel.
For a traffic data stream of nx64kbit/s, n+1 time slots have to be
configured for transparent B-channels.
When transmitting control line information, the following correlation exists
between the transmit and receive direction:
V.11 mode: Control (C) --> B-channel --> Signalling (I)
V.35 mode: RTS (105) --> B-channel --> DCD (109)
DTR (108) --> B-channel --> DSR (107)
Control line settings are made in the "Control lines" box of the "Various
Digital Settings" form.
The following settings are possible:
• Status unknown
• Without control lines
• Control lines permanently "ON"
• Loop control lines
• Loop control lines transparently

Adjusting the transmission of performance

parameters
In the "Digital Performance Monitoring" form, a performance measuring
point can be defined for the "Digital" FE of an nx64 data channel.
A storage depth of 15-min. and 24-hr. records is possible.
In the "Various Digital Settings" form, the transmission of performance
parameters can be activated or deactivated.
In case of performance parameter transmission, "n max" available for
traffic data transmission is reduced by 1 for each nx64 kbit/s data
channel.
Important:
The control lines and lines used for transmitting performance parameters
are sharing one 64 kbit/s slot.
→ If the control lines are transparent, traffic data capacity is not reduced.
→ If the control lines are not transparent, traffic data capacity is reduced.

The F2M Service Unit provides a fractionally occupied 2.048 Mbit/s
interface for point-to-point connections with nx64 kbit/s (1≤n≤30 in the
RNU, without time slot 0 transmission) in compliance with G.703, G.704,
G706; I.431 and ETS 300 011 as well as the national FTZ guidelines
FTZ1TR237 and FTZ1TR805.
Within the SISA information model, the SU-F2Mis represented by the
EPPM 64/ 2NT-S functional group.
The EPPM 64/2NT-S functional group is composed of EPI, D1NTP-S
Extended and D0CTP (TP index 0 to 31).
Starting with time slot 0, each D0CTP represents a 64 kbit/s time slot,
only D0CTP#0 to D0CTP#30 being switchable as Leased Lines with
SU-F2M. D0CTP#31 is not available, since this time slot is used to
transmit the internal communication channel between the SU-F2M and
ZE2 (ZE-8C in the RNU8C and RNU4M-8C).
D0CTP#0 can only be switched in the "Transparent" mode.
All D0CTPs not used are set to "not valid" by the CM. Thus, the OS

Configuration of EDI contacts

In order to be able to connect external alarm systems, the RNU can be
equipped with the SU-EDI module. In the RNU30 equipped with ANU-ZE
(A002) and in the RNU8C, the EDI sub-module is mounted on the main
board. In the RNU4M-8C, the EDI functions are integrated on the
ANU4M/8M-PS-DCDC module. An additional equipment with a SU-EDI
module is not permitted.

Signalling lines
The SU-EDI provides six (the EDI module five) optocoupler inputs. These
can be arbitrarily used for operator-specific purposes. For this reason,
their assignment is operator-defined.
The relay contacts of signalling lines 1 to 6 (or 1 to 5) can be configured
as NO or NC contacts.

Control lines S1 and S2

For controlling external devices, the SU-EDI module makes available two
control lines (S1 and S2), whereas the EDI module provides only one
control line. These can be activated or deactivated in the "NUControl EDI
Configuration" form. The relay contacts of the control lines can be
configured as NO or NC contacts.
