4 GENERAL PERFORMANCE DATA

Performance of any switching system is highly dependent on it‟s environment

(call mix, conditions of operation). The capacities given below are given

below are gived for information purposes, based on an average reference

environment.

Maximum processing capacity of the system is 280 CA/s, under CCITT B

load system (Q 543) – i. e. 1,000,000 BHCA.

The connection capacity of the host switching matrix ranges up to 2048 PCM,

which permits:

- Up to 25,000 Erlangs to be handled (on CCITT B load (Q 543)),

- Up to 200,000 subscribers to be connected,

- Up to 60,000 circuits to be connected.

In addition, the system possesses sophisticated regulation mechanisms which

make it possible to avoid saturation in the event of an exceptional overload.

These mechanisms, which are distributed at the level of each system resource,

are based on metering of the number of call presented and accepted, and also

on observations of processors load (occupancy rate, number of items in

queue).

1.2.2 Host switching matrix (SMX)

The SMX is a square connection matrix with a single time stage, T, duplicated

in full, which enables up to 2048 matrix links (LR) to be connected.

A matrix link LR is an internal PCM, with 16 bits per channel (32 channels).

The MCX can execute the following:

1) an unidirectional connection between any incoming channel and any

out going channel. There can be as many simultaneous connections as

there are outgoing channels. It should be remembered that a connection

consists of allocating the information contained within an incoming

channel to an outgoing channel,

2) connection between any incoming channel and any M outgoing

channels,

3) connection of N incoming channels belonging to one frame structure of

any multiplex onto N outgoing channels which belong to the same

frame structure, abiding to the integrity and sequencing of the frame

received. This function is referred to as “connection with N x 64

kbit/s”.

The MCX is controlled by the COM function (matrix switch controller) to

ensure the:

- set up and breakdown of the connections by access to the matrix command

memory. This access is used to write at the output T.S. address the

incoming T.S. address

- defense of the connections. Security of the connections in order to assure a

good data switching.

1.2.3 PCM controller (URM)

The URM provides the interface between external PCMs and the OCB283.

These PCM come from either:

- a remote subscriber digital access unit (CSN) or from a remote electronic

satellite concentrator CSE,

- another switching centre, on channel-associated signalling or CCITT No.7,

- the digital recorded announcement equipment.

In particular, the URM carries out the following functions:

- HDB3 conversion to binary (PCM matrix link),

- binary conversion to HDB3 (matrix link” PCM),

- extraction and pre-processing of the channel-associated signalling of T.S.16

(PCM command),

- transmission of channel-associated signalling in T.S.16 (command PCM).

One to five communication multiplexes are used to transmit messages from

one station to another. This transfer of messages is carried out by only one

type of medium, the TOKEN RING, with a unique protocol which is

processed in accordance with IEEE 802.5 Standard.

Single Multiplex (COMPACT configuration):

- It is then referred to as the interstation Multiplex (MIS).

More than one specialist Multiplex:

- 1 Inter station Multiplex (MIS) for interchanges between the

command functions, or between the command functions and

operation and maintenance software,

- From 1 to 4 Station Access Multiplexes (MASs) for interchanges

between the connection functions (URM, COM, ETA, PUPE) and

the command functions.

3 SOFTWARE MACHINE (ML)

This is software set (programs + data) which can be fitted on a SM and which

carries out a specific function.

One ML = an hypervisor-controlled execution unit.

One ML = a loadable unit.

A ML has an internal organisation (system + application) which is unknown

by the hypervisor and the other ML.

The ML is characterised by:

- a type:

which identifie the ML function, ( e.f : TR is the ML which

ensure the translator function). In function of the exchange load

and also for defence purpose, one type of ML can have more

than one examptar (e.g:2MLT,R).

- a system address:

for each ML there is one system address (AS). This address

used to identify the ML in the system.

- one or two archives:

system archieve.

- site archieve

one SM support:

in each station, an assignment file gives the addresses of the

physical stations which support each ML.

- a status.

4 REDUNDANCY

4.1 Redundancy at the SM and ML level

The OCB 283 redundancy depend of the SM station and the ML supported by

the station:

1) SMC:

- ML, TX, TR and MQ:

2 ML, supported by different SMC, are working in load sharing mode.

- MLMR:

n ML, supported by different SMC, are working in load sharing

mode.

- MLGX:

Two ML are used for the management and defence of the

connection

connection management: 2 ML GX working in load sharing

mode

defence of connections : one ML GX active on one SMC and

one ML GX standby on another SMC

- ML PC:

One SMC support the active ML PC and an another SMC support the

standby ML PC. The standby ML PC is updated permanently

- Standby SMC

One SMC could be use as a backup station. This station is fully

equipped in boards.

The activation of the standby SMC correspond to a station

initialisation. During the backup station initialisation, the traffic is

process by the other_SMC. At the end of the initialisation, the full

capacity of processing is restored for the exchange.

2) SMA:

- ML PUPE

Redundancy (n+1) that means n SMA with the active ML PUPE and

one SMA which support the standby ML PUPE. Software and semi-

permanent data are already loaded on the standby ML PUPE. The

ML PUPE switchover is done us in a real time data (circuit statuses).

The faulty SMA repared is put back to service and the PUPE

supported by this station is now the standby PUPE.


- MLETA

RGF (Frequencies sender/receiver) and CCF (conference circuit):

Redundancy (n + 1) that means than (n + 1) ML supported by

SMA are working in load sharing mode The over dimensioning of

the SMA allow to prevent a degraded working of the exchange.

GT (Tone generator):

Fully duplicated. The two first SMA contained all the tones

generator,

Only one GT in service is enough for the exchange,

3) SMT:

- SMT1G:

The SMTIG is fully duplicated and work in active/reserve mode. In

case of serious fault, the SMTI G can request itself for a switchover.

- SMT2G (Fully duplicated)

The SMT is working in load sharing mode with 0% of load on one sub-

system and 100 % on the other subsystem. During a soft switchover,

the traffic will pass progressively from one subsystem to the other.

4) SMX:

The SMX is fully duplicated. The connection drain defence is done by

association of specific mechanism (connection defence and SM defence).

5) SMM:

The SMM (with the OM function) is duplicated and work in active/reserve

mode. The SMM is independent for it‟s defence function (faults

processing restarted). It‟s duplicated structure is unknown by the other

stations. The total inaccessibility of the OM have no effect on the call

processing. The SMM have 2 hard disk working in mirror mode (writing

on both disk and reading on one).

4.1.2 Multiplex redundancy

One multiplex is done by 2 rings working in load sharing mode. The

access to the 2 physical channel is managed by a protocol which allow, in

case of problem on one ring, to save the traffic.


4.1.3 Power supply redundancy

The power supply distribution in each SM station is done by 2 converters.

The non duplicated boards (SMM coupler boards, PCM interface in the

SMT) are supplied by converters equipped in (n + 1).

4.1.4 Time base distribution redundancy

The STS (Time base station and synchronisation) is done by 3 oscillators

boards. Each oscillator board send the time base signal to SMX. In the

SMX a <<Majority Logic>> is done on the 3 time base signals.

4.2 Defence architecture

42.1 Principle

The element to be protected in the system are the SM station and the

communication multiplexes

The main defence principle are :

1) AttheSM level:

- faults self detection,

- hierarchical organisation of the detection responsibility in the SM,

- supervision of the SM by it‟s environment (the other SM) and

centralisation of the accusation for correlation,

- if a break down appear in one station, the fault will stay in this

station without disturbing the others stations,

- in case of serious fault, one SM can set itself to the block status,

- an SM station have a status, characterising its fitness to handle

traffic.

This status is knowned by the other stations,

- an SM is reconfigurable unit : in case of breakdown, its task will be

reallocated to another SM.

2) At the communication level:

- a multiplex (MIS or MAS) is constituted by 2 rings (A and B) and

self-protected,

- 3 levels of protection:

a) SM level: by the access protocol,

b) ring level: by equipment located in the adaptators,

c) system level: by the ring manager.

- the result of those protection should disconnect the faulty adaptator

in case of fault.


4.2.2 Defence function allocation

The allocation of the defence responsibility in the system leads up:

- decentralisation of the fault detection in the station,

- centralisation of the function which need a global view of the system

(management).

The OCB 283 defence function can be divided in:

1. a common core of mechanism identical for all the SM (independently of

the SM type) included:

- local defence on each SM:

fault detection

minor or serious fault warning and self-positioning if

serious fault.

- central defence in the OM:

* stations management:

SM working supervision

a positioning (broadcasting of the new SM state)

maintenance (initialisation, hardware test, alarm),

system general re-initialisation.

* ring management:

working supervision,

positioning,

maintenance.

* management of the PCM terminaison

(ending) SMT2G:

working security observation,

terminaison alarms,

terminaison fault processing.

2. Specific mechanism in function of the type of redundancy used

and the function processed:

defence of the connections

CCITT N°7 network management (MLPC).

1 ROLE OF MAIN CONTROL STATION

The main Control Station (SMC) supports the following functions:

MR (Call handler): call processing,

CC (Communication Controller): processing of the SSP

application, and ISUP SS7 calls.

TR (Translator): database,

TX (Charging): charging for communications,

MQ (Message Distributor): message distribution,

GX (Matrix System Handler): management of connections,

GS (Services management): SSP application,

PC (SS7 Controller): signaling network management.

According to the configuration and the traffic to be handled, one or more of

these functions may be supported by the same Main Control station.


2 LOCATION OF MAIN CONTROL STATION

The Main Control station is linked to the following communication media:

- the Interstation Multiplex (MIS) : it carries out interchanges of

information with the other Main Control Stations (SMC) and with the

SMM station.

- the main Control station Access Multiplex (MAS) 1 to 4 : they carry

out interchanges of information between the main control station, the

Auxiliary Equipment control (SMA), Trunk Control Station (SMT)

and Matrix Control Station (SMX) connected on those multiplexes,

- the Alarm Multiplex (MAL) : this transmits power alarms from the

station to the SMM station.

4.1 ACUTR board : processor

4.1.1 Role

With in the OCB283 system, the ACUTR board, which is organized

around a 68030 microprocessor (ACUTR3) or 68030 (ACUTR4),

constitutes a processing unit for multiprocessor stations which is also

called a Main Processor Unit (PUP) or a Secondary Processor Unit

(PUS).

4.1.2 Location

The ACUTR board is attached to:

- the Multiprocessor Station Bus,

- compulsorily, a local bus in the case of the PUP.

A Control Station can include one or more than one ACUTR board

connected to the Multiprocessor Station Bus.

Connection of an ACUTR allows transfers of data with slave boards in 32 bits

(ACMCS) or 16 bits.

Connection to the Multiprocessor Station Bus takes place in 16-bit mode

(address of less than 16 Megabytes) or in 32-bit mode (address of more than

16 Megabytes), The 32 bit mode enables the multiprocessor to be operated at

full capability (32 address bits and 32 data bits). This mode is used

automatically when the address sent by the 68030 exceeds 16 Megabytes.

4.1.3 General organization of board

A 32-bit processor:

- 68030 Motorola operating at 40 Mhz (ACUTR5),

The 68030 can access the following:

- one EPROM (128 kbytes),

- one Dram expandable up to 128 Mybtes, by adding 16, 32 or 64 Mbytes.

- registers (ICMAT, ICLOG….),

- a local bus interface,

- a multiprocessor station bus interface provided by the BSM gate array,

- a coupling area arranged within the BSM gate array.

4.2 ACMCS board: 16 Megabyte common memory

4.2.1 Role

The ACMCS board is the common memory of the 16 Megabyte 0CB283

control stations. It is protected by a self-correcting cod and can be accessed via

the BSM multiprocessor station bus and the local bus, (BL).

4.2.2 Location

It interfaces with:

- the multiprocessor station bus, a multi-master bus with access

priority. The data bus is a 16-bit one for addresses less than 16

Mbytes and a 32 bit one for addresses lying between16 Mbytes

and 4 Gbytes. To operate, the board must be linked to a master

board via the multiprocessor station bus,

- the local bus, which is a quick-access mono-master bus. The

data bus is a 32-bit one and it is accessible only t addresses of <

16 Mbytes. A link with a master board via the local bus is not

essential for the board to operate.

4.2.3 Organisation

The ACMCS board essentially includes:

- the multiprocessor station bus and local bus interfaces, a special

addressing area which is accessible via the multiprocessor

station bus only and is called a “link-pack area”. It is made up

of:

commands and status, registers,.

address translation filters,

- 128 memory blocks of 128 Kbytes (i.e. 16 Mbytes), accessible

via the multiprocessor station bus and the local bus,

- the arbitration access control and refreshing logic.


4.3 ACAJA/ACAJB boards

4.3.1 Role of the coupler

The coupler is organised around a 68020 or 68030 processor and makes it

possible to connect a station which includes a multiprocessor station bus to a

communication multiplex (token ring). The coupler is associated with the

relevant softwares and fulfils MIS coupler (CMIS) or MAS coupler (CMAS)

functions according to whether it is connected to an Interstation Multiplex

(MIS) or a Main Control Station Access Multiplex (MAS).

The coupler can serve as a station handler: for initialisation and loading

operations. In this case it‟s a “Main Multiplex Coupler” (CM F). If not, it is

called a “Secondary Multiplex Coupler” (CMS).

4.3.2 Location of coupler

The token ring coupler is

attached to:

- the multiprocessor station bus,

- rings A and B of one token ring.

4.3.3 General organisation of coupler

The coupler is made up of two boards, ACAJA and ACAJB. ACAJA is

organised around a Motorola 68020 32-bit processor which operates at

15.6MHz.(ACAJA4)

- 68030 operates at 40 Mhz (ACAJA4). It authorize programmable rate

of 4 or 16 Mb/s.

The processor can access the following:

- 128 Kbyte EPROM,

- 4Mbyte DRAM,

- registers (ICMAT, ICLOG,...),

- a Multiprocessor station bus interface provided by the

multiprocessor station bus gate array,

- a coupling area arranged within the multiprocessor station bus gate

array,

- two token ring adaptors: one located on ACAJA, and the other on

ACAJB.

These two boards are interconnected via a backplane private bus.

The power supplies of the two boards are different, in order to guarantee

absence of simultaneous disturbance of the two rings in the event of a power

fault.

The ACAJB board also makes it possible for the station number (“APSM =

physical address”) programmed on backplane to be read.

5 SOFTWARE ARCHITECTURE

5.1 Principle

Each station has the following software:

- an operating system, called HYPERVISOR (HYP), which function as a

hardware interface, software resources allocation and communication

with the other stations,

- a software in charge of the progression of the elementary task for an

software machine (ML), it‟s called SUPERVISOR (SUP),

- some software called SOFTWARE MACHINE (ML),

2 types of ML:

one or more than one functional ML. Each one have a specific

telephonic function (Eg. charging, call processing),

one ML (call station ML or MLSM). The is ML is used for

station defence, initialisation, down loading and communication.

HYPERVISOR, SUPERVISOR and MLSM, are loaded on all the stations

(SM). They are called the “ basic software” of the station. This software is

distributed on the different active agents of the station.

One given functional ML (Eg. MLMR) is loaded according to the

configuration needed.


5.1.1 Hypervisor

The HYPERVISOR is the operating system of the station. It gives the

possibility to each ML to be independent of it‟s physical location and allows

to load on the same processor of some MLs with different functions (Eg.

MLMQ, MLGX)

It carries out:

- Time management:

It assume the time sharing between the different MLs installed

on one agent using parameters given by the configuration file of

the SM.

- The communication:

Communication between the MLs is done by the hypervisor

without modification

- Time delay:

On request from one ML: start, re-start or end of time delay,

Signalling of over flow time delay,

Maintenance and access to time and date,

5.1.2 Supervisor

A Functional ML component executes one set of elementary tasks. Each task

corresponds to a service activation. Scheduling of those services is done by the

SUPERVISOR.

The SUPERVISOR in the Macro component is called a “SEQUENCER”.


5.1.3 System functions: MLSM

The MLSM Id divided and loaded on all the active agent of the station. The

MLSM software machine includes:

- the main MLSM component, which carries out:

loading of the station,

initialisation of the station,

positioning of the station,

defence of the station,

observation of the station,

- the secondary MLSM component, which carries out:

loading and initialisation of the agent,

defence of the agent,

observation of the agent.

In addition, MLSM components transmit messages to and from the token rings

when they are loaded on CMP or CMS couplers.

5.1.4 Functional software machine

A functional ML is a telephone application software. It‟s loaded on same SM.

It could be made by one or more than one software entities loading on

different agents of the station.

E.G: MLTX and MLMR include:

interchange component (Exchanger)

1 to 4 secondary components (Macro)

7 DEFENCE

- A station detects its own faults and signals its serious faults to its

environment. It is made up of a set of processors which are of multi-

level structure and co-operate for detection of faults.

- A station is monitored from the outside by its environment, thanks to

the other stations. This monitoring is Instituteed in order to offset

inefficiencies, if any, in detection mechanisms which are internal to the

station. it requires centralisation of potential malfunctions in order to

carry out correlation. For each malfunction is assigned. a level of

seriousness (weighting).

- A OCB 283 station is a confinement unit: confinement of any

confirmed -fault is carried out within the station and consists of

stoppage of the station. Traffic in progress within the station may be

lost in this case. !t will not have any degraded operation effect except

for the time it takes fault tolerance mechanisms to react,

- A station possesses a status, characterising its fitness to handle traffic,

vis-a-vis the outside. It also knows the status of all the other stations at

any moment, which allows it to re-switch its traffic if a change in

configuration of the station network takes place.

- A station is a reconfigurable unit - i.e. any station positioning

because of a fault will lead to re-allocation of all its tasks (ML) to a

backup station, if there is one.

4 PHYSICAL FORM OF AUXILIARY EQUIPMENT CONTROL

STATION

The Auxiliary Equipment Control Station is organised around a standardised

Multiprocessor Station Bus (BSM). This is a 16-bit bus. The different boards

are connected to this bus, which is used by them as a means of

communication.

Sixteen boards can be connected to the multiprocessor station bus:

- an ACAJA board makes it responsible for helping the ACAJB board to

manage interchanges via the Main Control Station Access Multiplex

(MAS),

- an ACMCS board which supports the bulk memory of the station

(1C),

- an ACUTR board : main processor function (PUP),

- an ACUTR board which constitutes standby call handling capacity

(PUS),

- at most 12 boards which carry out the specific operations for which the

Auxiliary Equipment Control Station is responsible:

one or more ICTSH board or ICTSS board.

one to four more ACHIL board,

an ICHOR board.

The following are inserted within the station but not connected to the

multiprocessor station bus:

- a pair of ICID boards, these ensure links between the branches of the

connection matrix and the auxiliary equipment control station,

- an ACALA board which is responsible for collecting and transmitting

alarms appearing on auxiliary equipment control station.

The structure chosen has the advantage of permitting a wide variety of

configurations or, at the same time, call-handling capacities (put into physical

form by the number of ACUTR). The operational capacity (according to the

number and the type of application boards) can be adjusted to a wide variety

of needs.

5.2 Functions performed by ICTSH board and ICTSS board

5.2.1 “Simultaneous communication between subscribers” function Putting a

maximum of four subscribers into simultaneous communication is possible.

This function allows:

- additive conference with discrete listening facility,

- indication of calls waiting,

- establishing of calls by operators.

This function implies addition of speech samples. Smoothing of level of

speech of different speakers is not provided.

Eight conferences with four subscribers are implemented on an ICTSH board.


5.2.2 “Tone generator” function

This enables voice frequency signals to be generated. These signals are

sequences of mono, bi, tri or quadri frequencies. A sequence consists of a

maximum of eight “transmission/silence” sequences.

Units used are:

- hertz for frequencies,

- decibel for sound levels,

- ms for timing.

An ICTSS generates 32 voice frequency signals. Frequencies and timings are

transmitted at initialisation of the Auxiliary Equipment Control Station and

remain fixed during phases of operation.

5.2.3 Frequencies receiving and generation (RGF) function

The RGF terminals analyse and transmit signals within the voice frequency

band. In general these signals are single or dual frequency signals pertaining to

a signalling code.

In OCB 283, one RGF terminal is dynamically sited by the command

components within a signalling code. It detects the presence of signals

received and transmits to the command stations the composition of this signal

(Frequencies).

On command instruction, it always transmits single or dual frequency pulses.

Sixteen RGF terminals can be implemented on ICTSS. Hypsometer codes are

processed as particular RGF codes.

5.2.4 Modulation detection function

This function allows operation of recorded announcements to be supervised.

Processing is like speech detector.

The modulation monitoring function is processed as a particular RGF code. It

is a software transmitted at the initialisation of the station and it determines the

type of function implemented by the board.


5.2.5 V23 function

This function consists in transmitting information to a subscriber‟s terminal

through the switching matrix unit. Upon the call processing request, the V23

questioning trans codes the pieces of information received from the MR and

sends them us the ferm of a digital train to the CSN. Once demodulated, this

train gives an on-line signal conforming the ITU-V23 recommendations.

The V23 modulation is used to provide the calling party identity as well as

messaging functions information on the line of the subscriber.

information.

5.5 Function performed by ICHOR board

The function of the ICHOR board is to keep the time of the OCB 283

exchange accurate. Time information performs a double function on

switching.

It enables messages to be determined and labeled.

It must be protected against slow drifts which involve repeated resetting of

time, and against sudden loss of time due to hardware anomaly.

5.6 Function performed by ACAJA / ACAJB coupling

This coupler makes it possible to connect the Auxiliary Equipment Control

Station to the Main Control Station Access Multiplex and carries out two-way

communication with the command units.

The following information are interchanged;

- channel-associated signalling coming from the ICTSH boards,

which are signals transmitted by the RF of the RGF specifying

the voice frequency signals detected,

- messages to and from applications implemented by the

processors present in Auxiliary Equipment Control Station

(positioning messages, semaphore messages....).


5.7 Function performed by the ACALA board

This carries out collection of alarms. This board is self-powered. In Auxiliary

Equipment Control Station the alarms transmitting entities are converters.

5.8 Functions performed by ICID board

The ICID board protects network/UR links. It supports the following

functions:

- receiving of the 8 matrix links and of an associated time base,

coming, via a RCID board, from a branch of the Host Switching

Matrix,

- transmission of 8 access links and 8 associated time bases to the UR

(SMA-SMT)

- inter-aids by receiving 8 matrix links coming from the other branch

of the SMX with the associated DT,

- synchronisation of the matrix links coming from the Host Switching

Matrix and the inter-aid matrix links,

- supplementary bits travelling on the matrix links,

- generation of the availability signal which accompanies the access

links,

- Generation of the inter-ICID inter-aid availability signal,

- processing of LAE links transmitted by the URs and generation of

LRE.

6.1 Principle

To operate within a Control Station environment the software machines (ML)

are supported on a basic software (Hypervisor) and on the system softwares.

The Hypervisor allows cohabitation of ML on one processor. It carries out:

- communication within the station,

- management of temporisations,

- time-sharing between ML or ML components being run on the

processor

The Hypervisor and system softwares assembly is pooled within a virtual

machine: Control Station

Taking place of the elemental tasks which constitute an ML or ML component

is carried out by the “Supervisor”.

2 ROLE OF SYNCHRONISATION AND TIME BASE STATION

The Synchronisation and Time Base Station incorporates 3 functions:

- External Synchronisation interface (HIS) clocks,

- Tripled Time Base (BIT),

- alarms.

2.1 Role of External Synchronisation Interfaces (HIS)

- The External Synchronisation Interfaces are synchronisation units

designed for synchronisation networks of master-slave type with more

than one input and with management of priorities. Putting one or more

than one input out of service and re-establishing them takes place

automatically, in terms of defined criteria.

- They use clocks retrieved from digital circuits coming from PCM

Terminal Stations (Trunk Control Station (SMT).

- They carry out management of synchronisation links by monitoring

alarm signals of the relevant PCM.

- They guarantee maximum quality of frequency precision, no matter

what the quality of synchronisation links might be.

- They offset losses from all synchronisation links, via a very high

stability oscillator.

2.2 Role of Tripled Time Base (BTT)

- This distributes the time.signals necessary to the Connection Network

Stations of the ALCATEL El OB OCB283 system.

- It uses the logic majority principle for time distribution and fault

detection in order to guarantee high reliability (tripled boards).

2.3 Defence

- This function makes it possible to transmit alarms generated by the

External Synchronisation Interfaces and the Tripled Time Base, onto

an alarm ring.


3 SYNCHRONISATION AND TIME BASE STATION ARCHITECTURE

The Synchronisation and Time Base Station includes:

- a Tripled Synchronous Time Base (BTT),

- an External Synchronisation Interface (HIS) which can be duplicated.

The synchronisation unit can receive 4 PCM clock from which 1 is selected.

The BTT is made up of 3 RCHOR boards.

The HIS is made up of from 0 to 2 RCHIS boards.

4 OPERATING RNL

The Synchronisation and Time Base Station automatically generates 4 sets of

operating conditions which guarantee:

- maximum autonomy,

- protection against any action which is dangerous for the quality of

frequencies transmitted and for safety of operation.

Normal Synchronised Regime

- The Synchronisation and Time Base Station is synchronised on one

reference from several.

Normal Autonomous Regime

- The Synchronisation and Time Base Station is no longer synchronised

(no longer any external reference).

- The frequencies transmitted are defined by the External

Synchronisation Interface in service (memorised value of HIS

frequency = value before external loss of synchronisation).

- Frequency stability within the temperature range of the steady state

operation regime, for 72 hours, is better than 4.10-10

BiT on Free Oscillationn Regime

- The 2 External Synchronisation Interfaces are out of service.

- The Tripled Time Base is no longer synchronised.

- it delivers its own frequencies (memorised value of the frequency of

each RCHOR = value before loss of External Synchronisation Interface

synchronisation).

- Frequency stability within the temperature range of the steady state

operation regime, for 72 hours, is better than 1.10-6

Free Oscillation Regime

- The station is used without synchronisation link

- Frequency precision is defined by factory calibration.

- It is in the order of 10-9

at commissioning (following a few months‟

storage).

1.2 SWITCHING MATRIX SYSTEM (CCX)

1.1 Role of the CCX

The Switching Matrix System establishes interconnections of time-domain

channels for Local Subscriber Digital Access units (CSNLs) and the Trunk

Control and Auxiliary Equipment Control stations.

In general, the Switching Matrix System carries out:

- unidirectional connection between any incoming channel (VE) and any

outgoing channel (VS). There can be as many simultaneous

connections as there are outgoing channels,

- connection between any incoming channel and any M outgoing

channels,

- connection of N incoming channels belonging to the same frame

structure of any multiplex to N outgoing channels which belong to the

same frame structure, abiding by, the integrity and the sequencing of

the frame received. This function is referred to as “N x 64 kbit/s

connection”.

A bidirectional connection between an A end (calling party) and a B end

(called party) takes place in the form of 2 unidirectional connections.

The Switching Matrix System thus ensures:

- switching between auxiliary equipment and speech channels for voice

frequency signalling operations,

- simultaneous distribution of tones and recorded announcements to

more than one outgoing channel,

- permanent switching of channels which support data links or

semaphore links between circuit and circuit, or between circuit and

Auxiliary Equipment Control Station.


1.2 Switching Matrix System organisation (OCX)

The Switching Matrix System pools;

- the Host Switching Matrix:

16-bit switching, including 3 reserved,

matrix of 2048 x 2048 matrix links with one time-domain stage,

64 matrix links equipment modularity,

- the Branch Selection function:

selection,

amplification,

interface of connection stations

(Local Subscriber Digital Access Unit, SMT.SMA ..,),

time distribution interface

- matrix links:

4 Mbit/s rate,

8 matrix links connection modularity.

1.3 Operation of Switching Matrix System

- Connections are established in both branches.

- Selection of the active branch for a Time Slot (TS) is carried out by

comparing the outgoing time slots of each branch.

- 3 control bits permit the following functions for each branch:

carrying, by Time Slot parity, from the incoming

Branch Selection to the outgoing Branch Selection,

setting, by matrix link, selection of the active branch,

monitoring connection on request,

metering of quality of transmission on request.

- Supervision of the unit is carried out by the connections management

software machine (Matrix System Handler GX).

- The 5 additional bits are not used.

2 SELECTION AND AMPLIFICATION OF BRANCH (SAB)

2.1 Description:

This entity is present in racks which have components connected to the

Switching Matrix System. These components are the Local Subscriber Digital

Access Units, Truck Control stations and Auxillary Equipment Control

Stations, referred to under the generic term of “Connection Units” or “URs”.

generates links (LRA for Host Switching Matrix a and LRB for Host

Switching Matrix b.


Processing operations carried out by this unit are:

1. amplification of matrix links on transmission and on receiving,

2. 8-bit/16-bit adaptation, preserving the 8-bit per channel,

3. processing of 3 control bits,

4. selection of branches,

5. time distribution interface between the URs and the Host Switching

Matrix.

6. access link interface on transmission and receiving.

The equipment modularity for this entity are:

3 HOST SWITCHING MATRIX (MCX)

The Host Switching Matrix is made up of 2 branches, A and B, and, form the

hardware point of view, is made up of Matrix Control Stations (SMX).

A branch of the Host Switching Matrix Contains from 1 to 8 Matrix Control

Stations.

Each Matrix Control Station receives a tripled time base signals (8 MHz and

frame synchronization) coming from the time base unit (STS) and, following

majority choice, distributes information to the exchange and to the Matrix

Link Interfaces (ILR).

Each Matrix Control Station handles 256 incoming matrix links and 256

outgoing matrix links, within its network liaison interfaces (ILR). On output

from the incoming side ILR, the LCXE links of homologous numbers are

multiplied on the same positions of all the Matrix Control Stations. Each time-

domain matrix is capable of handling the switching of any time slot of the

2048 incoming matrix links, to any time slot of its 256 outgoing matrix links.

Equipment modularity increments are:

- 64 matrix links for the time-domain matrix.(RCMT)

- 16 matrix links for the network liaison interfaces.(RCID)

4.3 Connection matrix part

The function of the connection matrix is to switch any incoming channel onto

any outgoing channel.

Operation is based on use of two types of dual access memory:

- Buffer type: this memory allows storage of samples relating to two

frames, with storage taking place at the strobe of the time base and

even frame alternating with odd frame in two buffers,

- Readout is performed from the control memory. Read/write switchover

takes place at each frame,

- Control memory type: the VEj address relating to the VEj -> VSi

connection is stored at each address memory which corresponds to the

VSi address.

This memory is written in upon instructions coming from the command units.

It is read out at the strobe of the time base.

The matrix has maximum capacity of 2048 incoming matrix links on 256

outgoing matrix links, made up of two 1024 LRE x 256 LRS modules.

Association of elemental matrices (64 x 64 matrix links) constitutes each

module.

The arrangement of 32 “columns” of 4 basic blocks makes it possible to obtain

the time-domain matrix of the Matrix Control Station, of maximum capacity

of 2048 incoming matrix links and 256 outgoing matrix links. Any

interconnection of time-domain channels goes through only one basic block.

Average time taken to go through is one frame (125 microseconds).

5 PROTECTION OF CONNECTIONS

5.1 Protection philosophy

The structure of the OCB 283 connection subsystem is duplicated. It uses two

identical branches.

Connections are made simultaneously in both branches.

Duplication is effective up to UR.

Connections are held if there is disturbance on a branch.

There is no traffic degradation if a component or the whole of one branch is

put out of service.

The host switching matrix handles 16-bit by

time slots:

- 8 “speech samples” bits,

- 5 free bits,

- 3 bits used for protection of connections (referred to as “additional

bits”). These are the 13 to 15 bits of the time slots carried by the LRE

and LRS.

5.2 Checking of connections

The aim of these checks is to detect the faults caused by transmission in the

switching system as well as the switching faults in the host switching matrix

(MCX)

Checks are of two types: permanent and on request.

Permanent check:

Permanent checks are based on permanent comparison of

data coming from two branches, on the one hand, and on

parity check for each channel, on the other,

The purpose of these checks is to signal any anomalies in

operation as and to operate automatic selection on the correct

branch.

The comparison : carried out by a bit to bit comparator

located in the SABs and connected on the each branch of the

MCX- provides the MCX- with the result of the comparison

performed on each channel.

Checks on request:

The purpose of these is to detect connection faults and also

transmission faults not detected by the parity check,

They are generally activated in order to complete permanent

checks and can concern only a limited number of channels

simultaneously.


5.3 Unidirectional connection check

Only the origins UR to TR destination is analysed on this page.

Permanent check:

The SABa1 and SABb1 send the data with the parity through the LRE al and

LRE b1.

The SABa2 and SABb2 received the data, check the parity, and compare bit to

bit and send the comparison result through the LREa2 and LREb2,

The RCIDa2 and RCIDb2 receive the result bit of the comparison and

memorized it. The reset of this information is possible only by the command

processor.

On demand control mode:

- The RCIDa1 and RCIDb1 boards send a synchronization frame, a

multiframe reference (connection and command field) and a CRC

control multiframe.

- The SABa1 and SABb1 receives the synchronization multiframes and

switch to multiframe working. It send through the LREa1 and LREb1 a

synchronization multiframe, and switch to multiframes working. It

send through the LRE a1 and LRE b1, a synchronization multiframe, a

- The RCIDa1 and RCIDB1, receives the data, detect the multiframe

synchronization, extract the connection and data field reference and

check the CRC. Those data are then change from serial to parallel.

- The communication of those data is realized by the RCMT and RCSM

boards.

- The RCIDa2 and RCIDb2 change the data from parallel to serial and

send it through the LRSa2 and LRSb2.

- The SABa2 and SABb2 board receives the data, detect the

synchronization multiframe, extract the connection reference and the

command field, and check the CRC. The SAB send back through the

LREa2 and LREb2 the multiframe synchronization, a copy of the

connection reference field plus an information field and a CRC field.

- The RCIDa2 and RCIDb2 receive the data, detect the multiframe

synchronization, extract the connection reference and information

field, check the CRC.

- The knowledge of the connection reference looped back by the SAB

and the data field of the SAB a2 and SABb2 containing the parity and

CRC fault result, allow to determined the faulty branch detected after a

fault of comparison.

2 TOKEN RING COUPLER

2.1 Characteristics

A Token Ring Coupler (ACAJQ).connects a station containing a BSM bus to a

communication Multiplex of the Token ring type.

With the context of OCB 283 there are two types of

Communications Multiplex:

- The Interstation Multiplex (MIS) (1 MIS multiplex for command),

- The Main Control Station Access Multiplex (MAS) (up to 4 MAS

multiplexes for the SMA – SMT and SMX).

Couplers which allow access to the MIS multiplex are called “CMIS”.

Couplers which allow access to the MAS multiplex are called

“CMAS”. Each multiplex is made up of two rings:

- Ring A

- Ring B

When both ring are in service, traffic is divided up over the two rings. If one

of the rings comes out of service the remaining ring must support all traffic.

Depending on its external positioning, a coupler can be called a “man coupler”

or a “secondary coupler”. The role of the main coupler is to provide

supervision vis-à-vis other components of the station.

The hardware make-up of a coupler is the same whether it is a CMIS, a

CMAS, a Main or a Secondary coupler.

Depending of the

Configuration, there is:.

1 to 4 MAS

Number MAS: 1 2 3 4

T S T T

MAS « S » used to connect the SMA containing the MLPUPE with or without

MLETA

MAS « T » used to connect the SMT, SMX and SMA with MLETA only.


2.2.1 Physical form

A Token ring coupler is made up of:

- An ACAJA board which comprises:

A mother board which supports the management part of the

coupler and ensures access to the multiprocessor station bus

(ACAJM board),

A daughter board (ADAJ) which supports access to Ring A. This

board handles Levels 1 and 2 of IEEE 802.5 Standard (the

topology of the ring and the insertion command do not meet

Level 1, and Level 2 is limited to the Framing and Access

Control),

- An ACAJB board which supports access to Ring B. This board handles

Level 1 and 2 of IEEE 802.5, with the same restrictions as the ADAJ

board. This board also makes it possible to read the Station Number

supplied by the Backplane,

- 2 AAISM mini-PCBs installed on the backplane perform the following

functions:

insertion of the adapter of the ADAJ board on Ring A,

the other insertion of the adapter of the ACAJB board on Ring B.

There are 2 Version of Coupler.

- ACAJA4 / ACAJB4 and ACAJA5 / ACAJB5.

The version 4 permits a flow rate of 4 Mbit/s, while the version 5 permits a

programmable flow rate of 4 Mbit/s or 16 Mbit/s.

The mixing of the 2 versions is possible as follows:

- ACAJA/B4 and ACAJA/B5 in the same 4 Mbit/s multiplexer,

- ACAJA/B4 and ACAJA/B5 within the same station,

- 4 Mbit/s and 16 Mbit/s multiplexes in the system,

Otherwise mixing of ACAJA4/B5 and ACAJA5/B4 is prohibited.

3 DESCRIPTION OF OPERATION

The elected station « MONITOR » (the one with the higher physical address

APSM) during the system initialization, synchronise the ring and send a free

token. This token goes from one station to the next one. Any station who need

to send a message mark the token busy and send it‟s message. Only one

message can go through the ring at the time.

a) The token is free: it is constituted by 3 bytes

If station A wishes to transmit a message going to c:

1. the token is marked busy by A,

2. station A sends its message to B which propagates it to C,

3. C recognizes its address, copies the information and respons

with an acknowledgement, (ARI to 1, FCI to 1)

4. in return, station: „A‟

detect the acknowledgement,

clears the information,

clears the token busy status (T to O)

4 COMMUNICATIONS

4.1 Domains and gateways

In the OCB283, 3 domains can be distinguished:

1. DS7 Domain (local no

signaling network) regrouping the

PUPE and CSN units.

2. DMIS Domain regrouping the central units {SMC (Main

Control Station), SMM (Maintenance station)}

3. DMAS Domain regrouping the Connection Units {SMT

(Trunk Control Station), SMA (Auxillary Control

station)} and network units {SMX (Matrix Control

Station)}. 1 to 4 DMAS exist depending on the

configuration.

For compact configuration, the DMIS and DMAS can be regrouped.


The domains are interconnected by gateway stations.

P1:

This is located in the SMA stations supporting ML PUPE.

In the context of signaling system 7, this is the passage point between the local

network and national network, and also responsible for performing the

gateway function between the DMAS and DS7 domains. It ensures

transformation from one protocol to another (no

7 code on the local network

and the internal OCB283 command MIS protocol).

P2:

The DMIS/DMAS and DMAS/DMAS gateway function is fulfilled by a

duplicated entity: the SMC stations supporting ML MQ.

It ensure message routing for dialogues between entities from two different

domains.

4.2 Addresses

SYSTEM ADDRESS:

In the OCB 283 system the software machine {ML} are designated by a

System Address [AS], with physical entities being designated by the System

Address of the management ML of that physical entity.

A System Address can also designate a group of entities. It can be:

- Of broadcasting type: each entity of a System Address group is

addressed,

- Of “or” type: an entity of a System Address group chosen in

accordance with a law is addressed.

Within the system, only ML can dialogue. Dialogue can be established

between two System Addresses, belonging to one and the same physical entity

and to one and the same domain or to two different domains.

Dialogue takes place from a source System Address to a destination System

Address, and is broken down into intra-domain dialogues (inter-domain

dialogues will use gateways).

PHYSICAL ADDRESS:

Within a domain each physical entity has its own Physical Address [AP],

which is known only to the dialogue and defence system functions.

Within a domain routing takes place in accordance with the Physical Address

of the physical entities support in the ML which dialogue.

An entity only knows the physical and logical links for the System Address of

it domain.


4.2.1 Interchange process philosophy

Example: Transmission of message from System Address “x” of a DMIS to

System Address “y” of DS7.

4.2.2 Example shown in functional layers

The System Address “x” System Address “y” dialogue is broken down into

3 interchanges:

1st interchange in DMIS between System Address “x” and System

Address “P2”,

2nd

interchange in DMAS between System Address “P2” and System

Address “P1”,

3rd

interchange in DS7 between System Address “P1” and System

Address “y”,

5 PRETECTION: RING MANAGER

The Ring Manager (GA) is the component which supervises the OCB 283

communications network.

It essentially permits 2 types of action:

Interventions on ring: maintenance of satisfactory working order,

tests,….

Observation of quality of such operation.

The main functions of the ring manager are

Real-time hold of configuration of rings,

Acquisition of faults transmitted by the adaptors (TMN function),

Testing of rings,

Forced disconnection of adaptor in order to ensure survival of the ring.

For effective management of the communications network the ring manager

must be capable of holding two-way communication with all the control

stations located on that network – i.e. on all the rings, in their entirety.

It is therefore made up of 2 types of unit:

Secondary ring manager entity (GA/S) which carries out acquisition

and switching for all the rings of the main control station access

multiplexes. (MAS‟s)

This GA/S is located on the main control stations which perform the

gateway function between interstation multiplex and main control

station access multiplex.

Note: For configurations with only one multiplex, neither gateway

function nor GA/S exists.

A main ring manager entity (GA/P) which carries out acquisition and

switching for all the rings of the interstation multiplex, and also all

processing operations.

The GA/P is located on the SMM.

5.2 Ring manager protection

- The secondary ring manager located on gateway stations is duplicated.

The principle of operation chosen is analogous to the principle of

operation of the gateway function: load-sharing when the 2 stations are

in service and the whole service carried out by one station when the

other is not in service.

- The main ring manager located on the SMM is duplicated. It operates in

accordance with the same principle as the MMS: active/standby. After

an Operation and Maintenance Software switchover the temporary data

necessary for the ring manager are either restored from the Operation

and Maintenance software disk (faults, for example) or re-booted from

the stations (rings configuration, for example).

3 FUNCTIONAL ARCHITECTURE OF SMM

3.1 Overall description

The SMM comprises the following sub-assemblies:

Two identical Multiprocessor Stations (SM), each built around a

processing system plus primary memory derived from the A8300

system and connected to the inter-station multiplex (MIS),

A Secondary Memory connected to small computer system interface

(SCSI) buses, which is accessed by either SMMA or SMMB,

External interfaces which are assigned to the active station.

In the duplex configuration the SMM consists of two Control Stations which

are physically identified by the acronyms SMMA and SMMB. One of the two

is the active or pilot, the other is the reserve.

4.1 The processing Units

There are two identical processing units (SMM A and SMM B), with only one

being in control at a given time. Each processing unit forms a SMM on the

Inter-Station Multiplex (MIS). It is designed around the XBUS bus (general

bus of the ALCATEL 8300 system).

The processing unit features the following boards:

- Two pairs of ACUTG – ACMGS board processor and memory

(connected by a local 32 bit-address bus),

- A pair of boards ACAJA/ACAJB for coupling with the Inter-Station

Multiplex (MIS),

- A coupler board ACFTD for managing the terminal bus interface,

- Two ACBSG boards for managing the interface between two SCSI

buses,

- A system board ACCSG,

Each processing unit has an interface with the MIS and an interface with the

secondary memory (disk, steamer, magnetic tape unit).

The 2 processing units each interface with a terminal bus via a dedicated

coupler board (ACFTD). The terminal bus carries the synchronous and

asynchronous communication line couplers plus the terminal couplers.

Each processing unit has one system board (ACCSG): the two system boards

control switchover between the two processor units (DUPLEX operation).

They dialogue via an HDLC serial link and exchange status signals

(Master/Reserve/Maintenance).

6.1 Brief description of the main alarm coupler (CCAL)

The CCAL is responsible for the acquisition of events (alarms, telecommands)

and relaying command signals to the supervision devices and miscellaneous

telecommands. It is also responsible for protecting the associated secondary

couplers and multiplex.

One ACRAL board can support 2 CCAL

6.2 Brief description of the alarm multiplex (MAL)

The MAL comprises:

- A data link (LAM),

- A clock link (H),

- A Pilot link (PIL) for setting the CSAL to Pilot or Reserve mode and

resetting them to zero.

6.3 Brief description of the CSAL

Each CSAL is supported by one ACALA board.

The main role of the ACALA board is to collect the alarms from an OCB283

stations. It formats the alarms into a serial messages for the Maintenance

Station (SMM).

It must also relay messages from the upstream ACALA boards, but this

function is transparent.

When requested by the SMM, it executes telecommands for the station in

which it is located.

It can also be used to position a 16-light alarm array via an interface board

(ACTLC). In this case it does not collect the alarms.

10 DATA MANAGEMENT

10.1 Type of data

The data are divided into three major categories

- Permanent

Data whose content does not vary in normal use. The instruction part of

software is a typical example.

These data are characteristic of a functional application and are generated

in the development centres. As such they are also called “system” data.

- Semi-permanent

Data which evolves during normal operation and requires storage in

nonvolatile memory so that they can be recovered when reloading the

system.

The semi-permanent data can be modified either by operator commands

(e.g. subscriber creation) of by the action of a subscriber. Semi-permanent

data can be divided into two subsets:

1) So-called “site” data which provide a record of the site environment

(subscribers, configuration, etc.),

2) So-called “contract” data which are identical for all sites in a given country

(e.g preliminary analysis data).

- Temporary

Data which can be dynamically regenerated. These data are either selected

by default (local data segment in a software when loaded into memory) or

deduced from the environment (circuit status, ongoing communication

context, etc.)


10.2 File

The data are grouped together in files. Like their content, these files also have

a type:

- permanent

file containing permanent data only,

- semi-permanent

file containing at least one semi-permanent data item,

- temporary

file containing temporary data only.

Insofar as possible, a file contains data of the same type.

10.3 Archive

An archive is a set of files described by a catalogue. The files making up an

archive form a coherent unit because they are trouped according to common

functional criteria, usually per software machine (ML).

- “site” archives, which contain semi-permanent data,

- “system” archives, which contain permanent and temporary files.

1 LOCATOIN OF SUBSCRIBER DIGITAL ACCESS UNIT (CSN)

The digital satellite exchange (CSN) is an entity for connection of subscribers

which is capable of serving analogue subscribers and digital subscribers

simultaneously.

Its design and make-up allow the CSN to be fitted into the existing network

and it can be connected up to all time-domain type systems using CCITT No.

7 semaphore signaling.

The CSN is a connection unit designed to adapt to a wide variety of

geographical situations. It can either be local (CSNL) or remote (CSND) in

relation to the connection exchange.

The CSN is broken down into two parts: the digital control unit (UCN) and the

Digital Concentrator Modules (CN). It is the digital control unit which can be

local or remote in relation to the connection exchange. Concentrators on which

subscribers are connected can be local (CNL) or remote (CNE) in relation to

that control unit.

Two distribution levels exist, therefore, which gives very great flexibility with

regard to geographical location.

- digital subscriber lines with basic rate of 144 kbit/s: 2 B channels + 1

D channel at 16 kbit/s,

- PCM links for connection extended-access PABX switchboards to 30

B channels + 1 D channel at 64 kbit/s, at primary rate.

3 FUNCTIONAL BREAKDOWN OF DIGITAL CONTROL UNIT (USN)

The Digital Control Unit (UCN) is the interface between the Digital

Concentrator Modules (CN) and the connection exchange. It is made up of:

- Two Control and Connection Units (UCX) operating in

Master/Standby mode. The Master UCX controls all the traffic and

updates the Standby UCX, on line. In this way, if there is a failure of

the Master UCX there is immediate Master/Standby switchover and the

Standby UCX which has become Master controls all the traffic, in its

turn,

- An Auxiliary Equipment Processing Group (GTA) which pools certain

functions associated with the UCX-viz:

- Generation of tones and of recorded announcements for local

communications on the occasion of autonomous operation of the

Remote Subscriber Digital Access Unit,

- Recognition of dual frequency signals from keyboard stations on the

occasion of autonomous operation of the Remote Subscriber Digital

Access Unit,

- Tests of Subscriber lines connected up to the Local Digital

Concentrator Modules,

As the Remote Digital Concentrator Modules are connected up to the Digital

Control Unit by PCM links, the role of the Remote Digital Concentrator

Modules Interface (ICNE) is to synchronise and to convert the PCM links into

network links which are internal to the Digital Control Unit.

A Connection and Control Unit (UCX) is broken down into two parts:

- The connection network (RCX),

- The control unit (UC).

The Subscriber Digital Access Unit has two levels of concentration. The first

is located within the concentrators, and the second is the Connection Network

(RCX).

4 DIFFERENT TYPES OF CONCENTRATOR

The different types of concentrator which can be connected up to the Digital

Control Unit are as follows:

CNLM: local digital concentrator for digital and analog subscribers,

CNEM: remote digital concentrator for analog subscribers and digital

subscribers.

5 CONNECTOIN OF SUBSCRIBER DIGITAL ACCESS UNITS TO AN

OCB283 (EXCHANGE OFFICE)

Connection of Local Subscriber Digital Access Units

Local Subscriber Digital Access Units (CSNL) are connected direct onto the

E10 connection network with the aid of from 2 to 16 matrix links. The first

two links carry CCITT No. 7 semaphore signaling, in TS16. The TSO cannot

be used to carry speech channels whereas TS16 are used for this when they do

not carry any CCITT No 7 semaphore signaling.

Connection of Remote Subscriber Digital Access Units

Remote Subscriber Digital Access Units (CSND) are connected up to the

connection network (CX) via a multiplex connection unit. Two to 16 PCM

connections are used for connection up the Remote Subscriber Digital Access

Unit. TSO cannot be used for carrying speech channels whereas the TS16 can,

when they do not carry any CCITT No 7 semaphore signaling.

Signaling: PCM AND 1 TS 16

PCM and 1 TS 1 to 15 + 17 to 31

PCM2<15TS1 to 31


6 CONNECTION OF DIGITAL CONCENTRATOR MODULES TO

CONNECTON NETWORK

The Local Digital Concentrator (CNL) are connected up to the Connection

Network with the aid of 2 to 4 internal Network Lines (LRI). All the TS16 of

these LRI are used for carrying High Level Data Link Control (HDLC)

signaling. This signaling permits 2-way communication between the

concentrators and the Digital Control Unit. The TSO cannot be used for

carrying speech channels.

The Distant Digital Concentrator (CNE) are connected up to the Connection

Network via the Distant Digital Concentrator Modules Interface (ICNE), with

the aid of from 1 to 4 PCM connections. The TS16 carry the HDLC signaling

and the TSO cannot be used for carrying speech channels.

A maximum of 42 LRI can be used for connection concentrators to te

connection network.

The maximum number of Local Digital Concentrator (CNL) which can be

connected to the connection Network is 19. This is because of the maximum

number of racks, which is 4. in this case the 42 LRI are divided up on the 19

CNL in terms of the traffic.

The maximum number of Remote Digital Concentrator which can be

connected up to the Connection Network is 20.

With CNE and CNL equipped the maximum number of CN is 20. CNE can be

equipped with from one to four PCM connections.

The ICNE allows a maximum of 42 PCM connections, divided up on a

maximum of CNE, to be connected.
