1.4 Protective Measures

1.4.1 General Notes

This section contains a summary of the most important requirements with regard to pro-tection of people and equipment. It does not claim to be complete. The installation in-structions listed are shown in detail in the relevant Installation Manuals.

All assembly, installation, operation and repair work may only be undertaken by properlytrained and qualified personnel.In the event of any injury (e.g. burns and acid burns) being sustained, seek medical helpimmediately.

1.4.2 Protection Against Excessive High Contact Voltages

When handling the power supply or working on it, observe the safety measures de-scribed in the specifications of the European Norm EN 50110, part 1 and part 2 (Oper-ation of electrical Systems) and the valid national country specific standards.

1.4.3 Components Subject to Electrostatic Discharge

Fig. 1.1 ESD Symbol

When packing or unpacking, touching pulling or plugging plug-in units bearing the ESDsymbol, it is essential to wear a grounding bracelet, which should be grounded to an rackor shelter when working on it. This ensures that the units are not subject to electrostaticdischarge.

Under no circumstances should the printed conductors or components of modules betouched. Take hold of modules by the edge only.

Once they have been removed, modules must be placed in the conductive plasticsleeves intended for them, and kept or dispatched in the special boxes or transport cas-

es bearing the ESD symbol.In order to avoid further damage to defective modules, they should be treated with thesame degree of care as new ones.

Modules which are accommodated in a closed and intact housing are protected anyway.

European standard EN50082-1 provides information on the proper handling of compo-nents which are subject to electrostatic discharge.

!Slide-in units bearing the symbol in Fig. 1.1, are equipped with components subject toelectrostatic discharge, that is to say the relevant safety provisions must be adhered to.

1.6 Environmental Passport

The aim of this environmental passport is to provide you with the most important envi-ronmentally-relevant information for this product. This means you can be sure that you

have selected a supplier who develops, produces, packs and ships their products in anenvironmentally-compatible way.

Product origination process

Even at the product origination stage we pursue the aim of minimizing the adverse ef-fects on the environment: We systematically record all product-related environmental requirements and take

account of these both in the product definition and in its development. Protecting the environment is a matter of course in our day-to-day work. This in-

cludes minimizing the consumption of paper by using the latest technologies (e.g.Internet, e-mail, database, 4:1 paper printouts) as well as multi-separation, heat in-

sulation and intelligent use of energy. We coordinate all environmental activities via a certified environmental manage-ment system which complies with ISO 14001. It is checked in accordance with theGerman certification body DQS (Deutsche Gesellschaft fr Zertifizierung von Man-agementsystemen mbH), quality and environment assessors. Certificate registra-tion No.: 66749-01.

Naturally we at Siemens are conscious of the fact that expenditure for environmentalprotection measures must be kept within an economically justifiable framework. After all,we still want to offer you this product with a price/performance ratio which is attractiveto you.

Manufacturing

Production facilities are equipped with the very latest, environmentally-friendly produc-tion machinery. Because of their minimal adverse effects on the environment theseplants can be operated without the need for special permits or notification. However theappropriate measures for reducing emissions are still taken in accordance with the stateof the art: Solder systems with condensate traps minimize both the deposition of solvents at

the workstation and emissions into the atmosphere Our manufacturing processes are completely free of CFCs, volatile CHCs (chlorinat-

ed solvents) and toxic substances. The heat generated from producing compressed air will be used for heating walkable

floor surfaces. Module production is practically waste-water-free since the use of low-residue fluxes

obviates the need for cleaning processes. Far more than three quarters of all production waste is fed back into the secondary

resources cycle. Only 0.5% of the production waste has to be disposed of as specialwaste.

Transport/shipping

The systems made by our company are shipped exclusively in environmentally-friendlypackaging: pesticide-free wooden packing cases, collapsible, reusable Cardboard boxes

Filling/stuffing: air cushions with polyethylene envelope

The Green Dot symbol for all packing for private end customers as a sign of ourinvolvement in Germanys dual system.

Energy consumption

The ever greater level of integration in components has significantly reduced the energyconsumption of the systems without affecting the normal features (number of channels,techn. refinements etc.).

The values for electricity consumption stated in the specification are maximum values.In normal mode they are far below the figures stated.

Power-down circuits also reduce energy consumption.

Taking back the product

Currently it is only possible to take back products when this has been regulated by priorcontract agreements.

Waste disposal

Basically the systems from Siemens Wireline Access Networks are produced withoutany hazardous or forbidden substances such Cadmium, PCBs, CFCs or such like. Oncethis product has reached the end of its useful life, it can be fraction separated and dis-posed of without hesitation in accordance with the current state of the art.

List of materials: Casing: Aluminum, steel, ABS plastic (flame-resistant)

Surface coating only when this is required by the customer. Modules: Normal electronic components (disposal as

electronic waste). The board material contains brominated

flame retardants. The following are to be disposed ofseparately: Electrolytic capacitors, LCDs and mechanicalcomponents (heat sinks)

2 System Overview

2.1 ApplicationThe CMXC crossconnect multiplexer is a compact solution to establish small networknodes at 8-kbit/s, 64-kbit/s and 2-Mbit/s level. It supports up to 48 2-Mbit/s ports andmakes it possible to switch 64-kbit/s channels between these ports without blocking.

The CMXC connects communication paths between the following signals: Max. 240 each with 8 kbit/s in the structure n 8 kbit/s (n = 1, 2 and 4) Max. 1488 each with 64 kbit/s in the structure n 64 kbit/s (n = 1 to 31)

64-kbit/s channels can be cross connected with and without signaling identification(CAS).

Max. 48 each with 2 Mbit/sThe 2-Mbit/s signals are available at 32 E1 por ts and 4 PCI interfaces

(each with 42-Mbit/s signals).Unframed 2-Mbit/s signals are switched through transparently.A frame selected from framed 2-Mbit/s signals can also be used as a referenceframe for signal processing in the CMXC.

The connections are usually bidirectional, but 2-Mbit/s and 64-kbit/s connections canalso be created unidirectionally or as a loop (loopback).

Fig. 2.1 CMXC Application (Example)

The crossconnect multiplexer offers the following possibilities: Switching a maximum of 48 framed (with and without CRC4) and unframed 2-Mbit/s

signals with up to 1488 switchable 64-kbit/s time slots Group switching of n 64-kbit/s time slots by complying with the frame integrity Bidirectional switching of up to 30 time slots (64 kbit/s) via a subrate matrix to switch

n 8-kbit/s channels (n = 1, 2 and 4) by changing the signal delays without process-ing the identification

Establishing scheduled jobs and path protection on 2-Mbit/s level

2.2 Structure

2.2.1 Overview

The following units belong to Crossconnect Multiplexer CMXC: One or two central CUCs (central unit cross connect)

The central unit contains the switching matrix via which the communication pathsare connected. A second central unit is connected in parallel for module redundancy.

Up to two interface PU16 units (port unit with 16 2-Mbit/s ports)The interface unit provides the 2-Mbit/s interfaces. One or two PU16s are equippeddepending on the number of desired interfaces.

2.2.2 External Interfaces

2-Mbit/s Interfaces (E1)

16 2-Mbit/s interfaces (E1in, E1out) are established for each PU16 unit.HDB3-coded PCM signals are received and sent at the E1 interfaces. They correspondto the ITU-T recommendation G.703/6.The line impedance 75 unsymmetrical or 120 symmetrical can be set individuallyfor each interface by means of jumpers (see Section 3.3.3).

PCI Interfaces

There are four PCI links on the central CUC for external connections to other systemmodules of FastLink (for later applications) via lines not exceeding 15 m. The PCI inter-

faces are proprietary, symmetrical interfaces with levels according to EIA RS422 andterminating resistors 100 serial in the transmit direction and 150 parallel in the re-ceive direction. The frame structure and time slot allocation of PCI links are containedin Section 2.2.2.

T3 Interface

For clock synchronization, a clock signal can be fed via interface T3in and sent viaT3out. The interface is on the CUC and corresponds to the ITU-T recommendationG.703/10. The input impedance of T3in can either be connected with high-impedance(1.6 kII < 120 pF) or with low-impedance (120 symmetrical/75unsymmetrical).

A clock signal is sent at T3out if the cross connect is synchronized by T3in or E1in of an

2-Mbit/s port. The interface is designed with low-impedance and is disconnected whenswitching over to the redundant CUC.

QD2 Slave Interface

The CUC has a QD2 slave interface according to EIA RS485 which forms the TMN ac-cess to the network element CMXC. Because the number of subscribers is not fixedfrom the start due to the bus structure and the possibility of different equipping, the in-terface is closed with high-impedance on the unit. Depending on the QD2 structure, thebus termination must be suitably fitted on the outside. Care must be taken that two busloads are active for redundant equipping of CUC (maximum possible number is 32).One QD2 address applies to active and standby CUCs.

ECC Interfaces

The ECC interfaces transmit control information from higher-level and to remote systemcomponents. The control information is integrated in an ECC channel (64-kbit/s timeslot) within a 2-Mbit/s signal. The central CUC provides four ECC interfaces. They con-form to ITU-T V.11 and can be accessed via the connector panel.

Two ECC interfaces are provided as synchronous interfaces (with clock lines) and twoas asynchronous interfaces (without clock lines). The synchronous interfaces are oper-ated with 64 kbit/s. Signal distortions of +5% to 10% are obtained for asynchronous op-eration with 9.6 kbit/s (or lower bit rates).

Alarm Contacts

The alarm contacts are arranged on central units CUC and are used to signal alarmmodes of the CMXC system module. They are established as floating relay contacts.Fig. 2.4 shows the allocation of alarm contacts for ZA(A). The alarm contacts ZA(B) aredesigned in an equivalent manner.

UMN CMXC

Alarm contact ZA(A) optionally signals prompt alarms (A alarm) or service alarms(S alarms) and the selection is menu-controlled. Alarm contact ZA(B) signals deferredalarms (B alarm). The software of both CUCs activates these alarms.

The criteria to release A, B and S alarms are given in the alarm table (see Section 3.3.2).

CCUR Interface

The symmetrical interface lines CCUR (according to RS485), signal redundancy opera-tion. Each CUC signals its active or standby mode via a separate line of the externalequipment so that these can switch over their PCI bus drivers.

2.2.3 Internal Interfaces

PCI Interfaces

The PCI interfaces transmit useful data between the CUC and units PU16. They also

distribute the clocks of the master clock from the CUC to the peripheral equipment.A PCI link establishes a point-to-point connection between the CUC and the two PU16svia two symmetrical two-wire lines (separately in the upstream and downstream direc-tion) on the rear panel. The external PCI interfaces (section 2.2.2) are established viawire pairs within a cable screen and can span distances of up to 15 m. Data signals withsymmetrical levels from which the frame and clock information is retrieved are transmit-ted via each wire pair.

The PCI frame contains 162 time slots with a width of 10 bits each. The CAS bit is notused in the CMXC and is loaded on fixed potential.

The PCI time slots are designed according to Tab. 2.1.

A useful load of 4 2-Mbit/s links with 32 PCM time slots each is mapped into each PCIframe as shown below:

Bit 1 2 3 4 5 6 7 8 9 10

LSI Interface

The LSI interface is established on PU16 (transmitter) and CUC (receiver). It consists of7 symmetrical line pairs and transfers the E1in guide clock from the PU16 to the CUCs.An 8th line pair transfers the frame pulse belonging to the E1 guide clock.Of the two PU16s, only one clock source may be activated per LSI line and the remain-ing transmit drivers are connected with high-impedance. The LSI interfaces are activat-ed via the software according to a clock priority list, see section 2.2.4.

Supervision Bus SVB

Internal communication between units CUC and PU16 takes place via the supervisionbus SVB. This bus is an HDLC interface which works according to the master-slave prin-ciple. The master (primary station) is the active CUC and the slaves (secondary station)the PU16 units.The standby CUC does not access the bus and the line drivers are con-nected inactively.

Supervision bus SVB is used for the following functions: Loading the software and configuration data of units PU16 during intitialization, Distributing the SISA messages via the active CUC to the SISA functional units of

units PU16, Module-internal communication between CUC and PU16

(e.g. control commands of the CUC to unit PU16 for clock source control).

CCUR Interface

There are two unsymmetrical connections between the units to signal the operatingmode of both CUCs and the PCI buses and their redundancy switchover. On PU16, onlyreceivers are connected to the record circuits whereas they are crossed between theCUC receive and transmit lines. A high level on line CCUR indicates that the left CUCis active and is connected via the primary PCI bus. In this mode, the CCURS line is atthe low level. When changing levels, a switchover to the redundant PCI bus and to theredundant central CUC takes place.

UMN CMXC

CC Interface

The CC interface (cross coupling interface with CC_I and CC_O) connects both CUCsand synchronizes the standby CUC via the clock master. The clock contains the fre-

quency reference and the position of the central multiframe synchronization pulse is im-pressed via a pulse duration modulation.

CCR Interface

The CCR interface connects both CUCs and synchronizes the PCI frame of the standbyCUC via the active CUC.

STSB Interface

Data is transmitted between the active CUC and the standby CUC via the STSB inter-face (status standby control). In this way the two CUCs run quasisynchronously andswitch over procedures can be released very quickly via the static command line(CCUR). The STSB interface is a point-to-point connection between the two centralunits inserted next to one another.

2.2.4 Clock Synchronization

For the CMXC function it is necessary that all the 2-Mbit/s signal streams E1in andE1out are applied with the same clock signal. This requirement is met if the signals atthe output of preceding equipment is derived from the same synchronous clock; other-wise is must be guaranteed by establishing clock loops in all the closed user terminals(transmitting clock = recovered receive clock). On violation of this principle, frame slipsoccur which lead to interferences in signal transmission.

The active CUC is the clock master for all the other CMXC units.

The 2-MHz guide clock can be derived from the following clock sources, see Fig. 2.5: T3in interface to feed an external synchronous clock, Regenerated clock signal which was retrieved from the E1in data of a 2-Mbit/s port Internal oscillator on the CUC (emergency operation).

7 symmetrical wire pairs LSI1 to LSI7 (line synchronization input) have been providedfor the E1in guide clocks from the PU16 units to the CUC. The source for the guide clockcan be selected at random from the 32 E1 ports. The software selects the activatedclock source on the basis of a priority list. This decides which one of the possible receiveclocks of the E1in ports are loaded on which of the 7 guide clock lines.

If PU16, which provides a guide clock, identifies a malfunctioning of the E1in signal, it

disconnects the corresponding clock source. The CUC then identifies clock failure andswitches over to the clock source with the next lower priority (see the alarm table of theCUC in Section 3.3.2). If all the external clock sources fail, the PLL of CUC is switchedto free-running and a prompt alarm is released.

If a clock source with a higher priority becomes available while operating with a lowerpriority standby clock, the guide clock switches over automatically.

24/152

24 A50010-A3-C800-1-7619


Fig. 2.5 CMXC Synchronization

Phase synchronicity requirements of G.703 interface signals can be found in the ITU-T-recommendations G.823 and ETS TBR-12 and they are formed by buffer stores and jit-ter reducers on units PU16. An elastic store sets up the frame synchronicity.

The synchronous clock on units PU16 is derived by means of PLL from the PCI down-stream signal.

For subsequent equipment, the active CUC provides a 2.048-MHz synchronous clockT3out which is synchronous to the current system clock.

Both CUCs manage the T3 interface. The software ensures that only the active CUC ac-cesses the interface.

2.2.5 Conferences

A maximum of 30 digital and 30 analog conference channels can be switched in up to20 mutually independent conferences at the same time. The requirements for analogand digital conferences differ:

For the analog conference, each conference participant receives the total of all the othersignals. Its individual transmit signal is deactivated. The identifications are switched dig-itally for the participants in analog conferences.

For the digital conference, the signals of all the participants are switched with bit-by-bitOR operation. Its individual transmit signal is retained. For the participants in digital con-

ferences, the identifications are also switched digitally as for analog conferences.

2.2.6 Subrate Multiplexer

To switch subrate connections, a subrate channel of 1, 2 or 4 bits is converted to 8 fullbits and then switched and compressed again. Conversion takes place by oversampling

or subsampling.A maximum of 240 bidirectional subbit rate signals each with 8 kbit/s in CMXC can beswitched.

2.2.7 Voice Channel in Common Frequency Radio Networks

In this application a voice channel is transmitted from one source to a number of desti-nations. The group delay time of the voice channel is constant here. There can only beone such connection within the network. This connection is always unidirectional.

The source can only be a VF interface in multiplexer FMX2R3 (with units CUD andUAC68). All subsequent multiplexers/crossconnect multiplexers must synchronize

themselves to the outgoing frames of the multiplexer with the synchronizing clocksource.

2.2.8 Redundancy Concept

2.2.8.1 Module Redundancy

To increase the operating reliability of CMXC, the central CUC is duplicated so that fur-ther functioning of the entire system is guaranteed if the unit fails. Failure of the activeCUC leads to a redundancy switchover if there is another CUC in the CMXC systemmodule. The software releases redundancy switchover. To this end, the operability of all

the components is supervised on both CUCs (active and standby).Units PU16 are not equipped redundantly, i.e. there is no protection switching if a PU16unit fails. Therefore, the CMXC system module has a fault penetration range of 16 E1interfaces.

Fig. 2.6 Redundancy Concept

The PCI buses are duplicated, see Fig. 2.6. A switchover to the redundant bus is pos-sible in case of faults. The central CUCs are connected to separate signal groups (PCISat standby unit).

However, the decentralized PU16 units are connected to both the bus systems. Theyreceive information about which one of the two PCI buses is active, the CCUR andCCURS signals (see CCUR Interface).

Bus STSB is used as the communication interface for redundancy operation betweenthe two CUCs (see STSB Interface).

The clock sources for the synchronous clock of CMXC is switched over to standby ac-cording to a priority list (see section 2.2.4).

Both CUCs manage the T3 interface and the QD2 interface. The software ensures thatonly the active CUC accesses the specific interface.

2.2.8.2 Alternative Route Switching for a 2-Mbit/s Connection

One alternative route can be configured for each 2-Mbit/s connection which is switchedover to for the alarm criteria below:

LOS, AIS,Local loop, remote loop always

SYN, BER-3, only for framed signals SYNK, AISK, only for framed signals with CAS signaling BER-5/-6 only for framed signals, if the alarm criterion

was switched on D-Bit, Dk-Bit, N-Bit, Nk-Bit never

The alternative route must be entered into the user menu.

The alarm criterion BER-5/-6 has a lower priority than the LOS, AIS, SYN, BER-3, AISK,SYNK, local loop and remote loop alarms. If a high priority alarm occurs at the one portand a low priory alarm at the other port, the low priority alarm will be used as the trans-

mission route. Therefore, the alarm criterion should be switched on.

2.2.9 Power Supply

Units CUC and PU16 of CMXC are supplied with an input voltage of 48 V (36 V to72 V). The input voltage is fed via a plug in the connector panel of the shelf. For redun-dancy operation, a second plug (S) is provided to feed a further 48 V. The active andstandby CUCs are connected to either of the two voltages in each case. The PU16 unitsare connected to both voltages. The input voltages are fed to the consumers via EMCfilters on the backplane of the shelf.

2.3 Operation and Supervision

2.3.1 Access to CMXC

The CMXC forms an SISA Network Element. The central CUC accesses the NetworkElement via the QD2 slave interface. Addressing the CMXC Network Element is allocat-ed slot-coded via the rear panel of shelf SNUS.

The following types of access are possible, see Fig. 2.8: CMXC connection to the OS via the QD2 slave interface

QD2 access is in stand-alone operation of unit SNUS via the supervision unit SUE.Switch positions connect the internal QD2 bus to the master port of the SUE.

LCT connection via the F interface of the supervision unit.

In stand-alone operation, the DCN channels are connected directly to the QD2 slaveport of SUE via the connector panel of the shelf.

Fig. 2.8 CMXC in Stand-alone Operation Mode (Example)

2.3.2 Operating Elements

The CUC has a jumper to set the impedance of the T3in interface to high-impedance(1.6 k II < 120 pF) or low-impedance (120 symm./75 unsymm.) operation (seeSection 3.3.3).

Jumpers are located on units PU16 to set the impedances of the E1 interfaces. The lineimpedance of each F1 interface can either be set separately to 75 unsymmetrical orto 120symmetrical (see Section 3.4.3).

A 5-step DIL switch is arranged on shelf SNUS to set the SISA address of the systemmodule (see Section 3.2.4).

Detailed information about the switch settings and plug connector allocations can befound in Section 3.

The E1, PCI and LSI interfaces are supervised according to alarm tables on the units(see Section 3.3.2to 3.4.2). the CUC supervises PCI and LSI links between the PU16 and the CUC. PU16 evaluates the E1 interfaces.

SISA0 alarms are reported to the OA&M computer. Two LEDs (red and green) on theCUC indicate the system alarms.

2.3.4 Diagnostic Functions

When switching on the input voltages for CMXC, self-test routines of the software andhardware components on the units are first of all performed.

In operation, PCM signals received at the E1 ports can be analyzed continuously ac-cording to ITU-T G.821 and the values stored in quality data records. Both the currentquality counter and any stored record can be displayed.

The number of frame slips occurring at a 2-Mbit/s port can be requested via the craftterminal.

The following loop connections can be established on PU16, see Section 3.4.1: Local loop for fault location within the CMXC system module, Remote loop for fault location of the external 2-Mbit/s connections.

The procedures for alarm evaluation are contained in the Section 5.

2.4 Software

The required SW of network element CMXC is loaded with the craft terminal and SWdownload via the V.24 or the QD2 interface. Special SW in the form of a file exists for

each CMXC unit.

2.4.1 Storage Structure

Each one of the units has a unit computer consisting of a micro controller and variousstorage circuits (FEPROM, EEPROM, RAM) for administering the software and the da-ta. The micro controller controls the internal functional flow on the individual units. Thestorage circuits are used for software and data protection.

In order to retain the configuration in case of a fault, backup versions are stored in theOS which can then be set up again at a later stage.

Firmware containing the initial program loader, self-test programs and type label data

are found on each unit. The firmware is stored in the flash EEPROM on the unit.

The RAM contains the current SW which is loaded from the FEPROM by the initial pro-gram loader.

2.4.2 Initializing

After power-up each unit starts the initial program loader software contained in theFEPROM. The initial program loader comprises the self-test routines of the unit (dura-tion a maximum of 30 s) and log-in into the supervision bus. After successful softwaredownload and starting, the units read-in their configuration data.

For an SW update, the current SW version carries on working in the RAM. A reset mustalways be performed after a new SW has been loaded, so that the unit can reboot.

3.2.2 Addressing

Almost all units in the SNUS are assigned addresses via the backplanes. The addressesassigned to the slots are shown in Tab. 3.1.

The SISA addresses of the SUE are set using DIL switch 101 in the terminal panel (pos-sible addresses: 1 to 30), see Fig. 3.6and Fig. 3.4.

Fig. 3.4 DIL Switch S101

The addresses implemented in the SNUS are shown in Tab. 3.1.

3.2.3 QD2 Structure

If the stand alone operation mode the SUE must be used for supervision. Operating ormaintenance functions can be carried out locally via an F interface using a local craftterminal. The SUE monitors all units in the SNUS. The internal QD2 bus of the SNUSmust be switched using switches S103 (all slider units on OFF) and S104 (all sliderunits on ON) to the SUE master port, see Fig. 3.2and Fig. 3.5.

Slave port 1 of the SUE is executed as a T interface, likewise the T connections are ac-cessible in the X101 slave connector, see Fig. 3.6.

Master port 1 of the SUE is stored in the QD2 X102 master connector and is the startingpoint of the internal QD2 bus when used in standalone mode. Further slaves in the in-ternal QD2 bus can be connected to X102.

Slave port 2 of the SUE is also located in the QD2 X102 master connector. The over-head interface of LT location 3 is also located here. Connection to slave 2 via an appro-priately assigned connector is possible and thus a control channel via the overhead froma remote device (unit in LT location 3 as a feeder for the SNUS).

Further control is possible via ECC channels. The ECC connections of both CUC loca-tions are stored in parallel and in a 25-pin D-sub connector. Of the four ECC interfacesof the CMXC, two are equipped with clock transmission. The ECC of the CUD is also

routed to this X131 D-sub.

The CUC allows conference calls for analog and digital signals as well as correspondingidentification processing (CAS conference). The total number of subscribers for confer-ence operation is 30. These can be a maximum of 10 analog and/or 10 digital confer-ences with 3 subscribers each and a maximum of 10 analog or 30 digital subscribers foreach conference.

The CUC performs the following functions: Crossconnecting the 64-kbit/s signals in the switching matrix and administering the

database needed for this Switching analog, digital and CAS conferences and administering associated data Clock generation by selecting the guide clock

Exchanging configuration and program information between CUC and PU16 via su-pervision bus SVB Data exchange between the CUC and PU16 units via PCI links Standby control Alarm signaling via ZA(A) and ZA(B) contacts and LEDs Providing the time.

The CUC has the following interfaces: Data

8 x PCIs as system-internal interfaces to transmit PCM signals between the CUCand the peripheral units PU16

4 x PCI interfaces for connecting external equipment
