Overview of Engineering for TCSM3i

2 Introducing the TCSM3i

The following sections describe the basic functionality of the new third-generation Nokia TCSM3i. The emphasis is on the hardwareimplementation of the system.

The TCSM is a functional unit of the BSC, but normally it is located in theMSC site in order to utilize to the fullest the transmission savings of thesubmultiplexing function of the TCSM. Both TCSM3i installation options(TCSM3i for standalone installation and TCSM3i for combined BSC3i/TCSM3i installation) can be located either at the same site with corenetwork elements or at a remote site. TCSM3i for combined BSC3i/TCSM3i installation is mounted together with BSC3i 1000 or BSC3i 2000.Transcoding capacity of the combined TCSM3i can be allocated to otherBSCs at the same site or to sites in other geographical locations.

For a general introduction, see Overview of Engineering for TCSM3i.

2.1 Overview of the TCSM3i in GSM/EDGE mobilenetwork

The Nokia GSM/EDGE third generation Transcoder and Submultiplexer(TCSM3i) provides transcoding for traffic channels in the GSM800/GSM900/GSM1800/GSM1900 digital cellular network. This function islocated in the Base Station Subsystem (BSS). The TCSM3i is used withthe Nokia GSM/EDGE BSC and the Nokia Base Transceiver Station(BTS).

The Nokia TCSM3i is based on modular software and hardwarearchitecture. The distributed architecture of Nokia TCSM3i is implementedwith a high-capacity and redundant multiprocessor system - the DX 200Computing Platform. The system enables the distribution of processingcapacity to several computer units with dedicated tasks.



Introducing the TCSM3i

The DX 200 Computing Platform Product Family covers a wide applicationarea in GSM/EDGE mobile networks and fixed telephone networks. TheDX 200 Computing Platform product family contains products for digitalmobile applications, such as Transcoder Submultiplexer(TCSM), BaseStation Controller (BSC), Mobile Switching Centre (MSC),) Home LocationRegister (HLR) and 2G Serving GPRS Support Node (SGSN), and alsocontains fixed network applications.

Together with the functionally distributed modular architecture of the DX200 Computing Platform and the latest commercially available industrystandard hardware components, the TCSM3i is easily expandable andcost-efficient and has high capacity.

Figure TCSM3i in the GSM/EDGE (and 3G) mobile network shows theposition of the TCSM3i in the mobile network.

Modular structure of the TCSM3i

The TCSM3i is designed with a modular structure enabling a distributedprocessing architecture. This quality, combined with the wide range of bothstandard and optional features available, makes it readily adaptable to theneeds of each individual operator, as it allows for capacity dimensioningaccording to individual need. External costs resulting from surplus capacityare avoided, and the operator can choose a selection of features andservices tailored to meet the demands of his customers. When additionalcapacity or new facilities are needed, the network element can easily beexpanded by adding new hardware and/or software modules to theexisting configuration.

The modular structure also allows for a compact design, which makes thenetwork element easy to install and helps to maintain efficient powerconsumption.

2.2 DX 200 system architecture and TCSM3i blockdiagram

Like the previous generations of DX 200 products, the TCSM3i consistingof a separate cabinet is designed with a modular software and hardwarestructure, which enables a distributed processing architecture. Thedistribution of processes is achieved by using a multi-processor system, inwhich the functions of the network element are divided among severalfunctional entities, called functional units. Each functional unit has aseparate task group to handle, for example, the external PCM lines areinterfaced by the Exchange Terminals (ETs).

Nokia TCSM3i High Capacity Transcoder Submultiplexer

The Nokia TCSM3i High Capacity Transcoder Submultiplexer consists ofone cabinet, the TCSA, and it is installed either at an MSC site or at a BSCsite.

Figure Block diagram of the Nokia third-generation transcoder presentsthe block diagram of the network element, which also shows the interfacesbetween the functional units and those connecting the system to theenvironment. Alternative A shows the standalone installation of theTCSM3i with ET interfaces and alternative B shows the combined BSC3i/TCSM3i installation with STM-1/OC-3 interfaces.

The hardware of the functional units and the tasks each unit handles aredescribed in more detail in the section Functional unit descriptions. Furtherinformation is available in the Product Description.

Interface



In the internal cabling of the combined BSC3i/TCSM3i installation, E1 orT1 interfaces are not used as Ater or as ETS2 control between BSC3i andTCSM3i. Instead, internal 8 Mbit/s PCMs are used as ETS2 controlbetween BSC3i and TCSM3i, and Ater interfaces are transmitted overHotlink/SBI interfaces between BSC3i and TCSM3i. STM-1/OC-3interfaces are used as external A interfaces.

2.3 DX 200 redundancy principles

The reliability of the operations in the DX 200 network elements has beenensured by backing up all crucial parts of the system following variousredundancy principles, as described in the sections below.

Redundancy of the functional units

Different redundancy techniques are used for backing up different types offunctional units. Each unit participating in the switching functions orrecording of statistical data is backed up according to the 2n redundancyprinciple, that is, by duplication according to the hot-standby or spare-device method. On the other hand, each signalling unit is backed upaccording to the n+1 or n+1/L principle. The former term means that thereis one spare unit available to take over the tasks of a faulty unit; in the lattercase, the workload is shared between all devices, and if one malfunctionsthe other units are able to carry the full load.

Redundant functional units should be consistent, owing to redundancyprinciples. The redundancy principle applied to each type of functional unitin the network element is given in the section Functional unit descriptions.

Redundancy of the power distribution, clock signal distribution andwired alarm collection systems

Virtually the entire power distribution chain from the rectifiers and powerfeed cables to individual pieces of equipment in the cabinets has beenduplicated to minimise the risk of downtime due to power failures in the DX200 equipment or cabling. On one hand, the redundancy for the powersupply from the rectifiers to the cabinets has been achieved by duplicatingthe power inputs in the cabinets, along with the input cables. On the otherhand, the cabinet is equipped with a duplicated power distribution and fuseunit, which allows for feeding the voltages to units backing each other upthrough two separate distribution lines.




Likewise, the DX 200 network elements have a duplicated clockdistribution and alarm collection system. The basic clock signal can be fedto each TCSM3i network element from up to four inputs, four from othernetwork elements (in the same network or PSTN) and four from externalsources.

Ensuring reliability at unit level

At unit level, the following methods are used to ensure proper operation:

. error correcting RAM in critical parts

. parity bit or ECC in read-write memories

. parity checks in data transmission

. reporting on certain error events in data transactions on the systembus

. memory area protection (standard Intel processor capability)

. automatic testing of connections

. time-out supervision

. validity checks for input data on different program levels

. vital data (for example, call/event data) in protected memory

. continuous supervision of the functioning of processes includingrestarts, when required

. continuous testing of operations (as background run) in all computerunits.

Backing up units without nominal redundancy

Some of the functional units of the network element are described ashaving no redundancy at all. These include, for example, the ETs andtranscoding units, that is, units which interface the network element to theenvironment. In fact, these units can also be backed up by ensuring thatthere is a sufficient number of circuits available in the same direction.

Another way to look at these units is to consider all units of a given type asa pool of resources, with several units available at a time to handle anassignment. A failure in one unit will only reduce the size of the pool butnot interrupt the traffic; consequently, redundancy for the pool as a wholecan be ensured simply by reserving some extra capacity for it whendimensioning the capacity of the network element.



3 Mechanical construction of the TCSM3i

The basic mechanical structure of the TCSM3i network element follows astandard hierarchy:

. cabinets

. cartridges

. plug-in units

. internal cables

The system is easy to install, maintain and operate. Particular attentionhas been paid to thermal and interference factors.

For a general introduction, see Overview of Engineering for TCSM3i.

3.1 Cabinets

IC209-B cabinet

The equipment of the TCSM3i network element is installed in a IC209-Bcabinet variant. The cabinet has a welded frame structure and it isdesigned following principles based on IEC, EN, ETSI, UL and Telcordiarecommendations, with advanced features in terms of safety, protectionagainst interference, stability, and durability.

The IC209-B meets the EN 60950 and UL 60950 safety requirements,along with the ETSI ETS 300019-1-3, Class 3.1E environmentalrequirements. The earthquake resistance of the cabinets is in accordancewith Telcordia GR63CORE Zone 4, and the EMC emission and immunityfeatures comply with the EN 300386 and (FCC) CFR 47, Part 15standards, respectively.



Mechanical construction of the TCSM3i

The IC209-B is dimensioned according to ETS 300119-2 standard. Theemphasis of the design is on easy transportability and suitability forinstallations in premises with normal room height. Due to the simplemechanical structure with relatively few components, the equipmentcabinets are easy to assemble and disassemble when necessary.

NEBS compliance

NEBS stands for Network Equipment Building System. It is a set ofTelcordia (former Bellcore) Standards, whose purpose is to unify HWrequirements and help Telephone companies to evaluate the suitability ofproducts for use in their networks. Compliance to NEBS is usually inquiredby RBOC's (Regional Bell Operator Company) in the USA. The DX 200Network Element Hardware is NEBS Level 3 compliant, covering GR-63-CORE and GR-1089-CORE in Central Office or equivalent premises, asapplicable for Type 2 equipment, as specified in GR-1089-CORE.

The IC209-B cabinet consists of the following parts (see Figure Equipmentcabinet IC209-B and its components:)

. Welded cabinet frame (IC209-B)

. one CPGO panel

. One Power Supply Connector Group (PSCG3-B)

. Power Distribution Fuse Units: two PDFU-B units

. four Fan Trays (FTRB-A) for forced cooling

A cabling cabinet variant (IC203-A) is attached next to TCSA (IC209-B) inStandalone TCSM3i deliveries. In the combined BSC3i/TCSM3iinstallation, the cabling cabinet is not used with the TCSA cabinet. Thecabling cabinet with balanced ET panels forms an optional set which mustthen be chosen for TCSM3i standalone installation option deliveries.IC203-A cabinet has new doors (D203-B) on both sides (front and rear).

The IC203-A cabinet consists of the following parts (see Figure Cablingcabinet and its components):

. Welded cabinet frame (IC203-A)

. Two CPETS-F panels (CPETC-F panels are to be orderedseparately)

. Three blank panels (CPBP)

. Doors rear and front, left and right

. Adjustable feet for permanent installation



Figure 5. Cabling cabinet and its components

3.2 Cartridges

In the design of the cartridges, particular attention has been paid todurability even under demanding conditions, along with dimensioning foroptimal use of cabinet space. One cartridge usually contains theequipment of one functional unit. Two types of cartridges are in use in theTCSM3i:

DN0487765




. 2 mm Hard Metric (HM) cartridges

. Euroconnector cartridges.

2 mm Hard Metric cartridges

The plug-in units in the 2 mm Hard Metric cartridges connect to themotherboards of the cartridges through Hard Metric connectors, which aredesigned in accordance with the IEC 1076-4-101 standard. Empty plug-inunit slots of the 2 mm Hard Metric cartridges are covered with shim plates.In the TCSM3i deliveries, the 2 mm Hard Metric cartridges come in twosizes:

. 1/2-shelf cartridge, comprising type TC2C-A

. 1/4-shelf cartridge, comprising type GT4C-A (indicated as ETC orGTIC in the graphics).

Figure 6. 2 mm Hard Metric cartridges and the cartridge shelf

Euroconnector cartridges

The Euroconnector cartridges house, for example, the ExchangeTerminals, interworking equipment, and clock equipment. The plug-in unitsin the Euroconnector cartridges connect to the motherboards of thecartridges by means of standard Euroconnectors.

In the TCSM3i deliveries, the Euroconnector cartridge comes in one size:1/6-shelf cartridge, comprising types CLOC-B, and CLAC-B.

The general cabling principles for the TCSM3i network element are thefollowing:

. Intracabinet cables connect plug-in units located inside the samecabinet.

. Most intracabinet cables are equipped on the left side of the cabinet,viewed from the back. There are some exceptions though, likePower Supply cables and cables connecting plug-in units located onthe same shelf.

. Intracabinet cables may include also cables that are connectedeither on the other cable end or on both cable ends to the frontpanels of the plug-in units. These types of cables can be equippedon either left and/or right side of the cabinet. Other cable end canalso be on the other side of the cabinet.




For further information on cabling, see cabling documents of the TCSM3i.



4 TCSM3i cabinet configuration andcapacity

This section describes the dimensions and configurations of the TCSAcabinet.

The TCSM is a functional unit of the BSC, but normally it is located in theMSC site in order to utilize to the fullest the transmission savings of thesubmultiplexing function of the TCSM. Both TCSM3i installation options(TCSM3i for standalone installation option and TCSM3i for combinedBSC3i/TCSM3i installation option) can be located either at the same sitewith core network elements or at a remote site. TCSM3i for combinedBSC3i/TCSM3i installation is mounted together with BSC3i 1000 or BSC3i2000. Transcoding capacity of the combined TCSM3i can be allocated toother BSCs at the same site or to sites in other geographical locations.

For a general introduction, see Overview of Engineering for TCSM3i, andfor further information on the equipping of the TCSA cabinet in TCSM3i forstandalone installation option and in TCSM3i for combined BSC3i/TCSM3iinstallation option, see Section Functional unit configuration.

5.6 Power Distribution Fuse Unit (PDFU) in TCSM3i

Purpose: The Power Distribution Fuse Unit (PDFU-B) distributes the -48V/-60V DC power fromthe site power system to the cartridges through the distribution cables. The PDFU-Balso contains the fuses for these cables, along with alarm circuits for the incomingvoltages and its own fuses.

Redundancy: 2n

Type: Functional Unit with no sub-units

Plug-in units: PDFU-B Power Distribution Fuse Unit

Interfaces: Supply interfaces to cartridges and site power system

Wired alarm interface

To ensure 2n redundancy for the power distribution lines, the TCSM3icabinets are provided with two PDFU-B, which are located in the upperpart of the cabinet and installed at the factory. One PDFU-B contains twoindependent functional units within one case, A and B. The feed cables arealso duplicated.

Each half of PDFU-B forms an independent feeding input branchconsisting of:

. connectors and circuit breakers for the incoming power cables

. an integrated filter for EMC protection

. connectors for alarm and outgoing power cables

. fuses for outgoing distribution cables: each half of a PDFU-Bcontains ten fuses

. indicators for blown fuses.

The circuit breakers for the incoming power cables have a 30A rating forPDFU-B and the fuses for the outgoing distribution cables a 10 A rating(Use Nokia part with manufacturer code 10511 20121).



Figure 17. The two PDFU-B units at the top of the TCSA cabinet

Power supply to the cabinets

The power feed cables from the site power system to the TCSA cabinetsare duplicated (one or two redundant power supply pairs). Each cabinethas supply cables of their own.

Power supply to the cartridges

On cabinet level, the operating voltages are fed to the cartridges housingthe functional units backing up each other through separate distributionlines, following the principles listed below and illustrated in Figures Powerdistribution diagram of the TCSA cabinet with PDFU-Bs with tworedundant power supply pairsand Power distribution diagram of the TCSAcabinet with PDFU-Bs with one redundant power supply pair:

. In some cartridges, each plug-in unit makes up a functional entity ofits own. These cartridges do not have any power supply plug-in unit.Instead, the plug-in units are equipped with onboard DC/DCconverters, and one half of the cartridge is fed by one PDFU-B whilethe other half is fed by the other. In the following figure, these typesof cartridges are referred to as 'type 1' cartridges. They include theCLOC-B and CLAC-B cartridges.

. Some of the cartridges do not have a power supply plug-in unit butonboard DC/DC converters in the plug-in units, and the wholecartridge is fed by one of the two PDFU-Bs. There is also an equalcartridge for backup that is fed by the other PDFU-B. In the followingfigure, these types of cartridges are referred to as 'type 2' cartridges.They include the GT4C-A cartridges.

. Some of the cartridges do not have any power supply plug-in unit.Instead, they have a certain slot area for plug-in units with onboardDC/DC converters. One slot area is fed by one PDFU-B while theother slot area is fed by the other. In the following figure, these typesof cartridges are referred to as 'type 3' cartridges. They includeTC2C-A cartridges.

The following figure shows power distribution diagram of the TCSA cabinetwith PDFU-Bs when two redundant power supply pairs (four 63A fuses)are used.

Power supply to the Fan Trays (FTRB-A units)

The TCSA cabinet is equipped with four Fan Trays (FTRB-A), each ofwhich contains five fans. Each FTRB is powered by a separate PDFU. Thefans are n+1/L redundant, meaning that if one of them fails, the remaining11 fans automatically start to operate at maximum speed, which is enoughto provide sufficient cooling.




6 Overview of the TCSM3i installation site

This section briefly describes the equipment room layout and some basicrequirements for the premises. For further information on the cables andcable structures, see Installation Site Requirements for Base StationController and Transcoder.

For a general introduction, see Overview of Engineering for TSCM3i.

6.1 Equipment room layout

Each cabinet should be located in the equipment room with free space ofat least 900 mm (35.4 in.) both at the front and the back, and at least 500mm between the end of a cabinet row and the wall. The recommendedspace between the cabinet rows is 1000 mm or, when the equipment roomhas a raised floor, 1200 mm. Any deviations from the above must beagreed upon individually.

In layout planning, the following aspects should be considered:

. cable structures for the power supply and PCM circuit cables

. room for expansion cabinets

. free space above the cabinet rows (height at least 500 mm).

Layout examples of a TCSM3i site

The Nokia TCSM3i for standalone installation option network elementconsists of one equipment cabinet, the TCSA, and a cabling cabinet (CC).The TCSA cabinet is also used in the Nokia TCSM3i for combined BSC3i/TCSM3i installation option. In the Nokia TCSM3i for combined BSC3i/TCSM3i installation option, the cabling cabinet is never attached to theTCSA cabinet.

The TCSM3i network elements are installed in rows with the other networkelements, as shown in the following figures.



Overview of the TCSM3i installation site

Figure Equipment room without raised floor presents layout examples Aand B of an equipment room without raised floor: two-row layout example(A) shows three Nokia TCSM3is for standalone installation option in onerow, and one Nokia TCSM3i for combined BSC3i/TCSM3i installationoption (BSC3i part is BSC3i 2000; number of ETs is 0…48) and one BSC3i2000 (number of ETs is 0…48) and one BSC3i 1000 (number of ETs is 0…48) in the other row. Note that the TCSA cabinet can also be installed tothe left-hand side of the BSC3i part as shown in example B, and that thenetwork elements can be installed from left-to-right as well as from right-to-left. The cabinets, however, must be positioned within the networkelements as shown in the figure.

Distribution frames are not system-specific and are therefore notdiscussed in Engineering for TCSM3i.

Cable trays

The DX 200 system construction does not comprise actual cable trays.The cable support construction arrangements for the external cables aredecided upon by the customer individually.

Power supply and consumption

The main input voltage of the TCSM3i can be 48 V or 60 V DC. Directfloating batteries can be used in both cases.

Special consideration has been given to keeping the power consumptionlow in TCSM3i. Maximum power consumptions are shown in the followingtwo tables.

Table 12. TCSM3i for standalone installation option

Power consumption ETSI ANSI

Per channel 0.14 W/ch 0.14 W/ch

Maximum operating consumption 1.6 kW 1.3 kW

For dimensioning site power supply 3.0 kW 2.7 kW

Power consumption ETSI and ANSI

Per channel 0.13 W/ch

Maximum operating consumption 1.5 kW

For dimensioning site power supply 2.8 kW

Operating power consumption figures are for full configurations of theTCSM3i. Power consumption for smaller configurations can be estimatedby multiplying the per channel power consumption with the configuredamount of channels.

7 Alarm system for TCSM3i

The task of the alarm system is to process the alarm signals collected fromthe network element and find the basic fault or disturbance behind thealarm condition. The alarm system tries to localise the unit in which adisturbance or a fault has been generated, after which the appropriateautomatic recovery functions can be activated.

Alarms are transferred over an operation and maintenance (O&M) linkfrom the TCSM3i to the BSC. Current alarms can, however, be viewed ona local MMI terminal. For immediate understanding at a local MMI terminal,the TR3E/TR3A software assigns a text string to the alarms.

Alarm functions of the system in the BSC include:

. collection of alarm data

. storing of alarm data

. output of alarms

. control of alarm printouts.

The BSC assigns an identity, a time stamp, an alarm class, a text string,and a physical location to each alarm. The BSC stores information on thephysical location of each piece of the TCSM3i equipment. It converts thelogical location information of the TCSM3i alarms into a physical address.Alarms which indicate that traffic channels, trunks, or other portions of thetraffic capacity are lost cause blocking of the respective elements by theBSC. The TCSM3i is not itself aware of the blocking measures taken bythe BSC.

The user is informed of failure conditions with alarm printouts in the BSC.The alarm system stores all alarm events on a disk. Alarm history storedon the disk can later be examined by means of the user terminal. With theuser interface, it is possible to cancel or block alarms, output alarm history,and change alarm-specific parameters.

7.1 Nokia NetAct network management system

Nokia NetAct is a network and service management system, whichprovides centralised management functions for different networktechnologies and network domains. Nokia NetAct can manage both thenetwork and the services in a centralised manner, meaning that theoperator can view the network element status, service quality indicatorsand traffic from a single screen. A network-wide view is always available.

A Unified Mediation and Adaptation layer (UMA) is the interface towardsthe different network subsystems, such as the BSS. The UMA isresponsible for collecting data from the BSS, such as alarms, events, andmeasurements. A unified adaptation to network elements and elementmanagers makes it possible to handle alarms and performance indicatorsin the same way regardless of technology or origin.

Nokia NetAct consists of functionality areas (for example, Monitor,Reporter, and Planner), which provide management capabilities groupedtogether according to the most relevant operator processes. For the BSS,there is an extensive set of management functionalities available, forexample the following:

. monitoring

. reporting

. planning

. configuring and optimising

. system management

. service quality management.

The hardware solution of Nokia NetAct is built of one or more serverclusters and operator seats. Regional clusters manage a specific region,while global clusters are intended for centralised network managementtasks. When distributing the operations between regional and nationalmanagement centres, the regional server clusters and third partymanagement systems are connected to the global cluster via a DataCommunication Network (DCN). The hardware includes the following:

. High-availability servers (HP-UX)

. Application servers (Windows and HP-UX)

. Operator seats

. Storage Area Network (SAN) with disk array

. DCN backbone.

8 Synchronisation for TCSM3iSynchronisation principles on the system level

The primary synchronisation method in the DX 200 network is based onthe so-called master-slave principle. In this method, the network elementsin a given network are hierarchically organised in such a way that anetwork element on a higher level in the hierarchy controls thesynchronisation of network element(s) one step below it. A DX 200network element which is synchronised to higher level equipment can, inturn, function as a synchronisation source for lower level equipment. Thesynchronisation signals are transmitted through the PCM /SDH lines.

If the connection to the master equipment is broken, the DX 200equipment can continue operation by switching into plesiochronous mode,that is by generating their own basic frequency without an externalsynchronisation reference. When the connection to the master equipmentis restored, the equipment will re-synchronise to the synchronisation signalcoming from the higher-level exchange or network element.

Architecture of the DX 200 network synchronisation

The DX 200 cellular network synchronisation plan is usually designed insuch a way that one of the exchanges in a PSTN or an ISDN networkfunctions as the master exchange and supplies the synchronisationreference to the MSCs in the cellular network. The synchronisation signalis also fed to each MSC from one or more other MSCs of the samenetwork, to ensure the availability of the synchronisation reference in casethe connection to the PSTN/ISDN is disrupted.

The MSCs, in turn, supply the synchronisation reference to the HLRs ofthe network, as well as to the BSCs via the TCSMs. To ensureredundancy, each HLR of the network receives the synchronisationreference from multiple MSCs, and each BSC from multiple TCSMs. Theredundancy of the synchronisation reference to the TCSMs and BSCs hasbeen arranged by supplying each reference signal through a separatePCM. The architecture of the network synchronisation system is depictedin Figure Synchronisation of the TCSM3i.

Internal synchronisation of the TCSM3i

Each DX 200 network element has an internal clock generator whichreceives the reference timing from external synchronisation sources(normally external PCM/SDH circuits) and generates pairs of basic timingsignals 8.192 MHz / 8 kHz which are distributed to all other plug-in units inthe network element.

The TCSM3i consists of one cabinet. Two Clock and Tone Generator(CL3TG) plug-in units are positioned in the CLOC-B cartridge of thecabinet for basic timing signals generation. However, instead of CLOC-B,the TCSM3i for combined BSC3i/TCSM3i installation is provided with aCLAC-B cartridge which contains two Clock and Alarm Buffer (CLAB-S)plug-in units for the distribution of the basic timing signals. The CLAB-Splug-in units in TCSM3i part get their timing from the CL3TG plug-in unitsin the BSC3i part.

Performance characteristics of the CL3TG in the TCSM3i are thefollowing.

Stability (at temp. +5 °C / 41°F to 40°C / 104°F)

< 3×10-7

Stability (due to ageing) < 5×10-9/day

Accuracy after loss of externalsynchronisation

- initially: +/- 1×10-9

- after one day: +/- 2×10-8

The number of external synchronisation inputs is four for PCM lines.

The following line coding/decoding standards are supported for PCMsignals.

ETSI version HDB3

ANSI version AMI and B8ZS

Redundancy -

Note that the ET16 and ETS2 plug-in units providing the higher hierarchylevel synchronisation signal are connected to different power distributionunits in order to ensure redundancy of the power supply.
