Technical Description (TED)
2 Introduction, ApplicationSynchronous line equipment SL64 is part of the TransXpress product family. It is suit-able for transmission of SDH signals, SONET signals, and plesiochronous signals.
On the line side signals with a bit rate of 10 Gbit/s will be transmitted. The transmissionmedium employed is single-mode optical fiber in the wavelength range around 1550 nm.The optical line signal is an STM-64 signal of the synchronous digital hierarchy. The ba-sic characteristics of the synchronous digital hierarchy are defined in ITU-T Recommen-dation G.707 (03/96).
On the tributary side (feeder side), depending on equipping, there are interfaces avail-able for:– electrical PDH-E4 signals and/or electrical STM-1 signals,– optical STM-16, STM-4 and STM-1 signals,– optical OC-48, OC-12, and OC-3 SONET signals– full duplex transparent Gigabit-Ethernet over VC-4 or VC-4-4v (1000Base)– full duplex transparent Fast-Ethernet over VC-4 (100Base)
For use with WDM units from Siemens special optical modules are available. With thesethe appropriate optical wavelength in accordance with ITU-T Recommendation G.692 isselected.
2.1 Network ApplicationsBy virtue of its modular design, Multiplexer SL64 can be equipped and configured in theoptimum way for all applications.
SL64 is suitable for all connections which impose the very highest demands on trans-mission capacity. The range of applications extends from simple end-to-end connec-tions through classical line networks for national or international connections –expandable with wavelength division multiplex systems – up to complex meshed net-works or ring networks with a variety of protection switching functions and operation asa local cross connect.
Chapters 2.1.1 through 2.1.4 show a number of typical applications.
2.1.1 Terminal-to-Terminal TopologiesTerminal-to-terminal links as shown in Fig. 2.1, are supported by SL64 network ele-ments in terminal applications.

3 System OverviewIts great flexibility in a great variety of interface modules for the very widest coveragemake the SL64 ideal for use in all capacity-intensive applications in every area of a com-munication network, from classical, meshed backbone networks, through highly-effi-cient ring structures (in Metropolitan networks for example) to corporate networks.
For optical networks too Multiplexer SL64 is an optimum feeder, interoperating with theDWDM units from Siemens to establish a future-proof infrastructure offering flexiblegrowth to accommodate the very highest capacity demand. This allows transmission ca-pacities of up to 2 x 3.2 Tbit/s on a single fiber optic pair.
Depending on the application, SL64 offers complete configuration flexibility for use asan add/drop multiplexer, a terminal multiplexer or a local cross-connect. Because of theextremely compact design (2 SL64 NEs in one ETSI rack), all these applications can becatered for using a single subrack (see 6.3). Reconfiguration during operation is possi-ble. Likewise the tributary interfaces – available for electrical 140-Mbit/s and STM-1 sig-nals as well as optical STM-16, STM-4 and STM-1 signals – can be mixed at any timeand replaced at any time.
Protection against device or line failures is of great importance, in particular for networkswith the highest capacities.
SL64 supports ”state-of-the-art” protection switching mechanisms to enable an optimumnetwork with the very highest reliability to be realized – depending on the relevant net-work topology and the requirements of the network operator (see 5.2).
Fig. 3.1 shows an overview of the hardware and software components which can beused.

Technical Description (TED)
The decision between LCT and NCT is made by installing the corresponding variant ofthat gateway software NE-UniGATE (see corresponding documentation).
The LCT software variant allows access to the local network element when it is connect-ed via the QST/F interface. When connecting via the QST/B3 interface up to 50 networkelements of a given address range can be called up at the same time (without the pos-sibility of a graphical network view).
The NCT software variant (connecting via the QST/B3 interface) allows all alarms to bemonitored which were reported by the network element to be reached in each case. Abackground bitmap can be allocated to each communication channel (preferably a map)which allows the network elements to be positioned according to their geographical po-sition.

3.3 Connection to Network Management SystemsThe telecommunications management network integration of SL64 network elements isrealized via QST/B3 (direct access) and QST/ECC (via dedicated OH channels withintraffic links – DCCM and DCCR). ECC routing is also possible via non-SL64 network el-ements (see Fig. 3.3).
The NE is equipped with a QST interface, which enables a managing system (EM, NCT,LCT) to control and to monitor the NE and to receive spontaneous messages createdby the NE.

4 Network Elements, Configuration TypesThe configuration types (SL64 network elements) described in Chapters 4.1 and 4.2 canbe realized with the universally-equippable subrack for SL64 (see 6.3). The MIB mod-ules and the SCU-R2 / SCU-R2E module of the device hold information on the NE type.This data can be read out with the aid of a craft terminal or a network management sys-tem.
4.1 Terminal MultiplexerThe SL64 terminal multiplexer provides multiplex-functionality for the tributary traffic tothe aggregate line signal in chain applications (Fig. 4.1).
Fig. 4.1 SL64 Terminal Multiplexer
The SL64 terminal multiplexer is equipped with a switching network and thus providescross-connectivity between the line and tributary interfaces at VC-4 level. On the tribu-tary side, a maximum capacity of 128 VC-4 equivalents may be mapped arbitrarily to theworking line interfaces.
The Fast/Gigabit Ethernet modules works at MAC sublayer level, i.e. they are fully trans-parent for different upper protocols like LLC and IP, IPX etc. running on the connectedIP equipment. ETH100/ETH1000 devices acts as remote bridge effectively convertingthe MAC protocol to SDH using LAPS encapsulation and mapping, allowing two ETHdevices to be connected together via SDH networks, capable of achieving far greaterdistances than those possible with conventional 802.3 LAN technology. The electricalETH100 acts via the ETH-LTU module; the ETH1000 has an optical interface.

Fig. 4.2 SL64 Add/Drop Multiplexer
SL64 add/drop multiplexer has two line interfaces for optical 10-Gbit/s signals (STM-64 /OC192) for which protection switching is optionally offered. At tributary side, a maximumcapacity of 128 VC-4 equivalents may be mapped arbitrarily to the west and east lineinterfaces.

4.4 Functional Overview of MultiplexersFig. 4.4 shows the basic functional structure (shown without line protection switching)of SL64 with the cross-connect-matrix for the VC-4 connection possibility between theline and tributary interfaces in a typical equipment.
In addition to the modules for the transmission of payload signals (line and tributarymodules, switching network module SNL64-3), the clock pulse supply module ClockUnit Line module CLL64 / CLL64-2, in which the clock pulse module is housed, the cen-tral control and monitoring module SCU-R2 / SCU-R2E and the overhead access mod-ule OHA are shown.
The telemetry interface TIF represents an interface for external signaling.
Conversion to optical/electrical signals (and vice versa) is taken over by the optical in-terface module OIS64 / OIS64-2 in the STM-64 transmission route.
The optical receiver of the bi-directional, optical interface module OIS64 / OIS64-2 con-verts the incoming STM-64 signal to an electrical signal by using a photodiode.
If required, optical preamplifiers OP and optical boosters OB can be used.
The electrical STM-64 signal is regenerated and converted to an internal ISDH signal onthe VC-4 plane (64 x STM-1). The VC-4 signals are relayed to the switching unit moduleSNL64-3 of the systems which forms the central element for the interconnection of theline and tributary signals in the VC-4 plane. The SNL64-3 allows connections betweenline and line, line and tributary and between two tributaries.
In the OIS64 / OIS64-2 module, the Section Overhead (SOH) is decoupled and writtento the internal OH bus of the system to allow an OH access of the relevant modules inthis way. DCC communicates via a separate internal bus system, the DCC bus.
In the tributary area a typical interface module is shown in each case along with its ports.There is a choice of tributary interface module with either four electrical STM-1 /140-Mbit/s interfaces, one optical STM-16 interface, four optical STM-1 interfaces, oneoptical STM-4 interface, one ETH100 interface, or one ETH1000 interafce:– EIPS1, STM-1el/140 Mbit/s: Each module has four bidirectional STM-1el/140-Mbit/s
interfaces which can be programmed individually for the desired bit rate.– ETH100, The Fast Ethernet Interface provides a full duplex transparent two-port
MAC level bridge. It connects together two physical seperated 802.3 LANs (e.g.campus) point-to-point via SDH network (WAN) at MAC sublayer level (remotebridge) with VC-4 capacity.

The incoming signal is regenerated in the tributary interface module (with optical tribu-tary signals optical/electrical conversion is undertaken first), the overhead is decoupledand the signal is converted into an internal ISDH signal (VC4) (Optical STM-16 tributarysignals are initially demultiplexed from the STM-16 level to the STM-1 level, optical
iFor conversion of the T3/T4 clock signal from 2048 kbit/s to 2048 kHz and vice versa anexternal Clock Line Adapter CLA can be used. In this case the SL64 device must beequipped with Clock Unit Line CLL64-2 instead of CLL64.

STM-4 tributary signals are initially demultiplexed from the STM-4 level to the STM-1level). The VC-4 containers are transferred to the SNL64-3, from where they are passedon to a line interface module OIS64 / OIS64-2 or to a further tributary module.
In the send direction the VC-4 signals selected by the SNL64-3 are scrambled after in-clusion of the section overhead. Where the STM-4/16/64 is involved, the signals areconverted at the STM-4/16/64 level. In the optical modules this is followed by electri-cal/optical conversion; for the electrical tributary modules CMI scrambling is performed.
For the line and tributary interface modules, the system can be configured in such a waythat the different ring and line protection switchings are supported. This takes place byallocating two interfaces which are housed on various modules and therefore functionas working and protection interface. To increase the availability of equipment, somemodules (OIS64, OIS64-2, OIS16, OIS16-2, OIS4, OIS4-2, OIS1, SNL64-3, and CLL64/ CLL64-2) can also have card protection facilities (see also Chapter 5.2).
SL64 provides concatenationconversion of contiguous concatenated VC-4-4c’s andVC-4-16c’s in virtual concatenated VC-4-4v’s and VC-4-16v’s and vice versa acc. G.707(10/00) via OIS4-2 / OIS16-2 modules.
Concatenated VC-4’s can be used for “high Bandwidth Streams” (> VC-4) establishedby IP Core Routers, ATM Core Switches etc. Because of the better performance (datathroughput), Clear Channel interfaces (contiguous concatenated signals) are generallypreferred by IP and ATM vendors. With Concatenation Conversion supported by SL64also Clear Channels resp. contiguous concatenated signals can be transported via es-tablished Multi-Carrier topologies even if they don’t support contiguous concatenation.– Contiguous Concatenation: Concatenated VC-4’s are treated as one single VC-4-Xc
(X = 4 ,16) with one common pointer and one POH.– Virtual Concatenation: Concatenated VC-4’s are treated as N individual VC-4’s (like
non-concatenated signals), each VC-4 having a valid POH. The POH byte H4 of ev-ery virtually concatenated VC-4 provides concatenation information: sequencenumber and multiframe number.
For fault supervision on conversion from virtual to contiguous concatenation, the alarmsLOM (loss of multiframe), SQM (Sequence mismatch) and LOA (loss of alignment) aresupported.
There are two models available for the configuration of concatenation:– Configuration via simple switch:
For each OIS4-2 and OIS16-2 module contained in the required equipping, the op-erator can easily enable / disable the concatenation conversion functionality via asimple switch (software “Simple Model”).
– Configuration via C-GTPs / V-GTPs:The operator can create contiguous (OIS4-2 / OIS16-2) or virtual (OIS4-2 / OIS16-2/ OIS64-2) Group TPs (C-GTPs / V-GTPs) which represents data relevant to the con-verter functionality (in case of C-GTPs) and data which has to be handled commonlyfor all CTPs concatenated by the C-GTP or V-GTP (bundles of 16 VC-4’s or 4VC-4’s).

Functionally the OIS16 / OIS16-2 modules subdivide into the optical front-end and SDHprocessing parts.
The optical front-end includes the optical/electrical conversion (photodiode), optical re-ceiver, data and clock recovery, laser driver and control and electrical/optical conversion(laser). The SP/PS converter provides the necessary speed matching from/to the CMOSlevel.
SDH processing takes place in 4 ASICs of type S6MD and comprises most of the SDHfunctions (with exception of the SPI block). Each ASIC operates 4 STM-1 equivalents inreceive and transmit direction.
Tab. 4.2 gives an overview of some special features supported by the OIS16 / OIS16-2modules.
4.5.3.3 Forward Error Correction FECFEC is a function of the optical STM-64 or STM-16 interfaces (only OIS64-2 andOIS16-2 modules) to considerably reduce the bit error rate, by correcting bit errorswhich may arise during the optical-electrical conversion at the receive side of the trans-mission line. This improvement can also be utilized to reduce the necessary optical pow-er of the transmitter.
The inband FEC applied utilizes the otherwise unused space within the SOH to transmitFEC parity bytes to the receive side. Thus the signal bit rate remains unchanged.
As FEC is a Siemens proprietary procedure, it is not useful in combination with NEs ofother manufacturers.
The FEC hardware functions are implemented in the ASICs S6MD-2 and S6MD64FEC.
Transmit Side
Fig. 4.7 shows the principle transmit-side functions.
The STM-64 and STM-16 signals can be seen as byte interleaved STM-4 part signals.The arithmetic-logic unit calculates the FEC parity bytes from the four STM-1 signals #1

These FEC parity bytes are inserted into the SOH of the STM-1 signals #2 to #4 of theSTM-4 part signal. Both SOH areas, RSOH and MSOH, are used for the transmissionof the FEC parity bytes. The SOH of the STM-1 signal #1 is not used for transmission ofFEC parity bytes, so there are no restrictions in the use of that SOH.
If the Enable/disable software switch is open, the SOH of the STM-1 signals remain un-changed.
Fig. 4.7 Principle FEC Functions at the Transmit Side
Receive Side
Fig. 4.8 shows the principle receive-side functions.
The received STM-4 part signal is applied to a delay unit and to an arithmetic-logic unitwhich calculates the correction information from the received STM-4 part signal andFEC parity bytes. By means of this correction information, bit errors of the received, de-layed STM-4 part signal are corrected by inverting the defective bits.

4.5.3.6 Optical Preamplifier (OP/OP64) ModuleThe Optical Preamplifier module performs the low-noise optical preamplification of thelight input signal in front of the optical receiver. The optical preamplification is transpar-ent to the signal content and optical signal parameters other than added noise power.The Optical Preamplifier works in the wavelength range between 1530 nm and 1560 nmand requires high-return loss (HRL) connectors. To reduce preamplifier inherent noise(amplified spontaneous emission) adaptive narrow-band optical filtering is implemented.
The OP and OP64 modules differ in their output power level. The OP64 is to be usedexclusively in conjunction with dispersion compensation modules.

Unidirectional and bidirectional connections are also supported such as drop and con-tinue traffic.
The integrated PCU takes over monitoring and control of the complete module.
Two SNL64-3 modules can be equipped for protection switching purposes. They areconnected with the optical interface modules on the West and East line sides, the tribu-tary interface modules, the two CLL64 modules for the T0 system clock pulse and theSCU-R2 for control.

An EIPS1 module equipped in tributary slot #9 operates as an EIPS1 protection modulefor 1:n protection switching (where n = 1...8). In the case of a fault, this EIPS1 takes overtransmission from a faulty EIPS1 working module in one of the slots #1 to #8.
The PCU of the EIPS1 protection module controls the switch settings of the interfacemodules LTU64 and of module EBSL64. On lines X (see Fig. 4.15) the signals of fourtributary ports are transmitted between the LTUs and the EIPS1 modules in each case.If there is a fault on an EIPS1 working module (#1 to #8) its signals will be diverted usingswitch A of the LTU64 to line Y.

Technical Description (TED)
The EIPS1 module contains 4 bidirectional interfaces (port 1 to 4). These can operateindependently in both the SDH (STM-1) and PDH mode (140 Mbit/s). The selectedmode for a port always applies to both signal directions.
Fig. 4.16 shows the basic mode of operation of the EIPS1 module using a block dia-gram.
The symmetrical signals supplied by the LTU64 module to the four independent tributaryports of module EIPS1 are processed further in different ways depending on the soft-ware configuration (STM-1 or 140 Mbit/s):• STM-1
– Signal conversion between external STM-1 signals (LTU64) and internal ISDHS(SNL64-3)
– Identifying fault conditions during signal conversion (Fault Management)– Forming quality data (Performance Management)– Processing defined OH bytes from RSOH and MSOH– Relaying clock pulse information from the incoming STM-1 signal
• 140 Mbit/s– Signal conversion between external 140 Mbit/s signal (LTU64) and
internal ISDHS (SNL64-3)– Identifying fault conditions during signal conversion (Fault Management)– Forming quality data (Performance Management)– Processing defined OH bytes from the POH
The four ports are configured (Configuration Management) via the Peripheral ControlUnit PCU on EIPS1. Incoming alarm and quality data is evaluated and relayed by thePCU. The PCU communicates with the SCU-R2 / SCU-R2E and other modules via thebus connections (PBUS/ICB).
The Power Supply Unit PSU converts the input voltage from nominal 48 V/60 V to thevoltages needed on the module.

4.5.3.10 Line Terminating Unit (LTU64) Interface ModuleThe LTU64 interface module is required for each EIPS1 module. It contains neither aPCU nor a PSU. The voltage is supplied via the PSU of the appropriate EIPS1 module(ULTUX) or via the PSUTP64 module (ULTUY) (if available).
Tasks of the LTU64:– Supplying external port connections– Converting tributary signals at the inputs of unsymmetrical external interfaces to
symmetrical internal signals for the 4 EIPS ports in the receiving direction.– Converting symmetrical signals of the 4 EIPS ports in transmission direction to un-
symmetrical external interface signals at the tributary outputs.– Safeguarding the electrical requirements at the external tributary input and output
interfaces.– Monitoring the level of external tributary input interface signals referring to the mini-
mum values for LOS identification.
The block diagram (Fig. 4.17) shows the functional blocks on the LTU64 module.

Technical Description (TED) InformationSL64-3.3
The incoming signals (port 1 to 4) from the trib-in connectors on the LTU64 are convert-ed in block IN from 75 Ω unbalanced signals to internal balanced signals. Block IN fulfillsall electrical requirements for the tributary interface.
The ASIC S4PS1 contains the switches A and B for balanced signals for one port. Thestate of the switch control input SCLA controls the position of the 8 switches A togetherfor 4 ports in receive and transmit direction.
The internal balanced signals are converted in block OUT to the outgoing 75 Ω unbal-anced signals (port 1 to 4). This block as well fulfills all electrical requirements for thetributary interface.
4.5.3.11 Fast Ethernet Interface Module (ETH100)The ETH100 card is a plug-in module for the SL64 NE on tributary side. In order to pro-vide the required transparent MAC-bridge functionality an ETHn counterpart at the re-mote end of an SDH path is required.
It is possible to plug in up to 16 ETH100 cards into one SL64 NE.
The ETH100 is managed by the board controller PCUD which connects to the SCU-R2/SCU-R2E System Controller via the Internal Communication Bus ICB.
The Ethernet interface allows direct interaction with the IP world.
The ETH100 design provides 4 LEDs for status indication. The LEDs H1-H4 are locatedat the front panel and are dedicated to service technicians.Tab. 4.3 lists the functional assignment of the LEDs. The LEDs H3-H4 are of smallersize (SMD type) and for debugging purposes only. H3-H4 display the status of the inter-nal link (ETH100 ↔ LTU-ETH).
The ETH100 does not contain the 100MB connector for EMI and ESD reasons. The FastEthernet signal lines (one differential signal pair for transmit and one for receive direc-tion) and the FE management bus are routed through the SIPAC connector to the back-plane where the LTU-ETH (serving as a repeater) connects to them. The LTU-ETHhosts the standard FE connector of the type RJ45 wired in DCE fashion.

4.5.3.13 Line Terminating Unit Ethernet (LTU-ETH) Interface ModuleThis module is the companion for the ETH100 module for solving the external signal ac-cess.
Due to ESD reasons the 100MB cable shield has to be connected to chassis frameground. This is not feasible on the ETH100 board so that the cable attachment on a LTUslot is preferred. This board is called LTU-ETH and contains a standard 8-pin RJ-45Ethernet connector as well as a link LED (green) and an activity LED (yellow). Datatransfer to the ETH100 card is performed using internal transmission lines on the SL64back plane.
The Fast Ethernet signal lines (one differential signal pair for transmit and one for re-ceive direction) and the FE management bus are routed through the SIPAC connectorto the backplane where the LTU-ETH (serving as a repeater) connects to them.

4.5.4 Modules for Central Tasks
4.5.4.1 Clock Unit Line (CLL64 / CLL64-2) ModuleThe clock pulse module of the system is housed in module CLL64 / CLL64-2.
The clock pulse module synchronizes the system either from an STM-N line signal or atributary signal or from one of the two external 2048-kHz clock pulses. The clock pulseoscillator of the system can be used in the following modes of operation with corre-sponding accuracy: “Synchronized”, “Hold-Over” or “Free-Running”.
In the standard case, the CLL64 selects the clock pulse source on the basis of a priorityspecified by the user. However, the selection can also be made by remote control via anLCT or TMN. The synchronization status report (“Timing Marker”) is supported.
Status, alarm and control information are transmitted via the integrated microprocessorunit PCU from/to the module.
Fig. 4.21 shows the clock pulse generation on the Clock Unit Line using a block dia-gram.
The input resistance of external synchronization input T3 can be configured via a switchon the connection board of the subrack (75 Ω unsymmetrical/120 Ω symmetrical).
The T3 Interface has overvoltage disconnection and amplitude monitoring.
The synchronization status message (SSM) of the OH bus is evaluated and the newSSM is inserted in the OH bus. The Timing Reference Selection identifies a possiblefault confirmation in the received SSM or a T3 signal failure and takes care of convertingto a new source (forced mode or automatic selection can be configured).
In the T0 Distribution switching unit, four different clock pulse frequencies and a 15-minute pulse are generated and distributed via the T0 bus or T0155 bus. T0155 is dis-tributed directly as T0 Traffic Processing Clock to the transmission modules OIS64 /OIS64-2, SNL64-3 and EIPS1. The four different clock pulses of the T0Bus are neededfor OH/DCC processing, internal system communication as well as for time information.

A 2048 kbit/s timing reference signal T3/T4 carrying SSM/QL information is supportedwith a special common mode DC-transmission superimposed to the 2048 kHz clock sig-nal in balanced mode between CLA and NE.
The CLA operates with an input voltage of 48/60 V from station power supply in the rackand is neither supervised nor controlled by the NE.
A green LED indicates the status of the CLA module. In case of a fault, only the “loss ofsynchronization” message in the dedicated NE using the CLA signals points indirectlyto the CLA which may be faulty.
The block diagram in Fig. 4.22 shows the functional blocks of CLA.
iFor using this feature the following conditions have to be fulfilled:The NE has to be equipped with a compatible CLL64-2 card / module (see Chapter4.5.4.1) and furthermore the T3/T4 connector has to be set to 120 Ω.

is also squelched.
4.5.4.3 System Control Unit (SCU-R2 / SCU-R2E) ModuleThe SCU-R2 / SCU-R2E is the central processing unit of the SL equipment and here thesoftware functions SEMF (Synchronous Equipment Management Function) and MCF(Management Communication Function) are processed. On the one hand, it controlsand monitors the transmission system modules and, on the other hand, it forms the in-terface to the LCT/NCT or a management system. In addition, interferences occurringin the SL equipment (including interferences of the SCU-R2 / SCU-R2E itself) are report-ed via the local alarm signaling according to the signaling diagram of Bw7R both at theSubrack Alarm Panel SRAP-PI and the higher-level monitoring devices.
Internal control takes place via the ICB bus system which connects the SCU-R2 /SCU-R2E processor to the PCU processors of the other modules. A second bus systemwith the designation PBUS (Protection Bus) connects the SCU-R2 / SCU-R2E to themain signal modules. This bus is used as “Express channel” to process communicationtogether with the protection switching measures and this way takes care of a quick con-version. Both buses form part of the internal communication system ICS.
The SCU-R2 / SCU-R2E system control communicates• with the other modules (via the internal ICS communication system),• with the ECC, QST/B3 and QST/F interfaces (via the MCF function),• with the rack alarm lines and the alarm bus of the operating point via the relay con-
tacts (see also Fig. 4.27).
The SCU-R2 / SCU-R2E carries out the following functions:• It monitors all alarms of the equipment and relays the alarm conditions to the net-
work system, the rack alarm bus and a LCT/NCT terminal.• It relays the operating data of the synchronous line equipment to the network man-
agement system and a LCT/NCT terminal.

• It identifies each module within the synchronous line equipment.
Functional Description of the SCU-R2 / SCU-R2E
Fig. 4.23 shows the basic mode of operation of the SCU-R2 / SCU-R2E module usinga block diagram.
In the SCU-R2 / SCU-R2E module, a RISC processor is employed as CPU (main pro-cessor ), and three additional CISC processors (peripheral processors ) extend theCPU interfaces as slaves.
A supervision module (T0 Supervision ) ensures automatic changeover to the standbyclock in the event of a fault.
The RTC module (real time clock) contains a NVRAM (non-volatile random accessmemory) with 8 kilobytes memory capacity. It is battery buffered to supply time informa-tion and store the test results and status information of the boot software. During shut-down, the clock pulse oscillator automatically switches OFF to protect the battery. Whenthe system is installed for the first time, the time and the date have to be set.
The Program Memory with a maximum capacity of 32 Mbyte (flash PROM) is used forstoring the operating software, basic software and application software.
The Main Memor y can be equipped with EDO DRAM up to 64 Mbyte memory capacity.
The Boot-EPROM with a capacity of 512 kilobytes stores the boot software for initiatingstartup of the operating software. The boot software only loads a specific portion of theoperating software from the flash memory which in turn starts up the remaining part ofthe operating software. Prior to loading of the operating software, the boot software per-forms a complete hardware test.
The Card Label Memory is designed as serial EEPROM and is used to store the mod-ule-specific data.
The Power Supply Unit converts the input voltage from nominally 48 V / 60 V to the volt-ages required on the module. The input voltage supply is duplicated to provide en-hanced reliability. The voltage is monitored: a red LED on the module lights up in theevent of a fault.

G.703– four data channels with an interface according to ITU-T Recommendation V.11– a 2-wire interface for an engineering order wire (2-wire Handset)– a PBX-Interface– two 4-wire-E&M-interfaces (only transparent mode)
In the case of synchronous failure, an AIS signal is inserted in all G.703 outputs accord-ing to the G.703 guideline.
The integrated PCU takes over monitoring and control of the complete module.
Fig. 4.24 shows the basic mode of operation of the OHA module using a block diagram.
The Power Supply Unit PSU converts the input voltage from nominal 48 V/60 V to thevoltages needed on the module.

The OHB Interface consists of two 6.48-Mbit/s interfaces for “Add” and “Drop” to trans-mit the OH bytes between OIS1, OIS4, OIS64 / OIS64-2, EIPS1, CLL64 / CLL64-2 andOHA. The OH bytes can be configured freely.
4.5.5.2 Telemetry Interface (TIF) ModuleThe telemetry interface module, TIF, represents an external signaling interface.
The module supports two groups each with 8 input ports (sensors) and 8 output ports(actors).
The two groups are selected via hardware switches on the TIF module. In addition to thehardware setting, the TIF interface must also be activated per software via the OHAmodule and management interfaces for LCT or TMN.
For data exchange between TIF and OHA, two serial 64-kbit/s channels with G.703 in-terface are used. If the TIF function is active, these may not be used for other purposes.
Fig. 4.25 shows the basic mode of operation of the TIF module using a block diagram.
Fig. 4.25 Block Diagram of Telemetry Interface TIF
Switches 1 and 2 specify how many and which 64-kbit/s channels can be used by theTIF (neither of the two; channel 1; channel 2 or both channels).
The internal timing generator generates the clock pulses needed for the Controller andthe ASIC module DC64.
The Controller has the task of resetting the ASIC module DC64 and generating the64-kbit/s signal.
The Serial/Parallel converter S/P converts the serial output signal to an 8-bit parallel sig-nal or the 8-bit input signal to a serial signal.
iThe TIF module is not shown in equipping representations, because it has no access tothe internal ICS communication system, but is controlled via the OHA module.

4.6.1 Subrack Alarm Panel SRAPThe subrack alarm panel SRAP is used to display a defective subrack in the rack. It con-tains the LED displays A, B and EL as well as the RT reset key. The LEDs are suppliedwith a constant current derived from the signaling voltage +S/–S and the SCU-R2 /SCU-R2E module. The signaling voltages +S and –S are insulated electrically by thecentral supply voltage and the module supply voltages in which case the display ofalarms is also ensured should the equipment supply voltage fail.

The phone indication PI of the SRAP-PI contains four LEDs for the signaling of servicechannel connections.
The LEDs of group Ι on the Phone Indication Panel PI (Fig. 4.28) are controlled by mod-ule OHA1, those of group ΙΙ when a second OHA module is used by module OHA2 (notin this software version). An incoming call will be indicated by the corresponding LEDflashing (e.g. Ι #1), after the call is connected the indicator LED is lit continuously. Twoindependent EOW conference calls #1 and #2 (express and omnibus channel) can bedisplayed.

5 Functional Features
5.1 Operation, Control and MonitoringThe payload signals are transmitted on the path as STM-64 signals. It is possible to in-sert and decouple plesiochronous 140-Mbit/s signals and/or synchronous STM-1,STM-4, STM-16 (or SONET) signals on the tributary side. In addition to the payload sig-nal, control, monitoring, customer-specific data signals and service telephone signalscan be transferred in the section overhead of the STM signals.
To ensure high operational safety, ongoing operation is continuously monitored by usinga network management system or by operating terminals.
Network elements to which no special operating terminal has been connected, give in-formation about the operational state for support in the case of maintenance work viabuilt-in display elements (see Chapter 5.1.1).
The controlling network management system or a local operating terminal LCT, commu-nicates with synchronous line equipment via its SCU-R2 / SCU-R2E control module(Master). This is connected with the peripheral computers, PCUs (Slaves) of all modulesof the specific line equipment via an internal communication system.
The core piece of the PCUs is a microcontroller which processes the alarm, status andcontrol information of the module.
The SCU-R2 / SCU-R2E control module not only establishes the connection to the localand remote control equipment (MCF function), but also monitors all internal functions ofthe synchronous line equipment (SEMF function). The flexible monitoring concept ofsynchronous line equipment based on software control can easily and quickly be adapt-ed to various user requests and offers optimum requirements for future changes.
The following alarm and error messages are given:– Optical messages via LEDs (module, subrack),– Bw7R alarm messages,– Messages via the QST/F interface,– Messages via the QST/B3 interface.
The synchronous line equipment is integrated in the following management functions inconformity with the corresponding ITU-T Recommendations and ETS standards:– Fault Management– Configuration Management– Performance Management
The following are of particular importance:– Alarm processing (e.g. AIS) for localizing faulty equipment in the transmission net-
work.– Fault diagnosis at module level (e.g. localizing a faulty module).– Specifying and storing configuration data; the data can be entered and requested by
the network management system or the LCT.– Determining the quality parameters according to the ITU-T Recommendation
G.826.– Administration of the access authorization in the LCT for various user classes with
passwords.

Technical Description (TED)
5.1.1 Display and Operating Elements of the Network ElementThe display elements (LEDs) at the subracks (see Chapter 4.6.1) and on the modules(see Fig. 6.4) are a useful aid particularly if neither a Local Craft Terminal, LCT, nor anetwork management system have been connected to the SL equipment when an alarmoccurs. The LEDs signal alarms at subrack and module level.
5.1.1.1 Display and Operating Elements of the Plug-in ModulesEach plug-in module has two LEDs on the front which are used for information in thecase of maintenance work:– A red error LED to display module-internal alarms. It is fed from an externally sup-
plied voltage (ULED) so that it can also illuminate when the module power supplyfails.
– A green Service Status LED to display that the module has been put out of opera-tion.
5.1.2 Control and Monitoring by the LCTThe Local Craft Terminal, LCT, is a Management PC for TransXpress network elementsof the second SDH generation. It is suitable for both communication with a directly con-nected, local network element and remote network elements which have been connect-ed via data connections.
With the LCT, simple and quick access to the parameters of the network elements (NE)which can be set in a transmission range is possible. The following basic functions be-long to this: addressing, configuring, alarm monitoring and display of performance data.
The LCT therefore offers the following network management functions according toITU-T M.3010:– Fault Management– Configuration Management– Performance Management
To allocate an equipment address (initial commissioning), the LCT is connected locallyto the QST/F interface of the NEs (see Fig. 5.1). The LCT can then be operated locallyat a specific NE or centrally for all NEs of a partial or total network depending on the ap-plication.
In local operation (e.g. for initial installation), connection takes place via the QST/F inter-face (ITU-T V.24) and in central operation via the QST/B3 interface (via a Medium At-tachment Unit MAU). The last mode of operation allows an accelerated data transferwith an effective bit rate of approximately 2 Mbit/s via the Ethernet.
The increased data rate of the QST/B3 interface is particularly advantageous for shorttransmission times for file transfer (software download) and access to remote networkelements (remote login). Remote Login is only possible via the QST/B3 interface.
The interfaces at the synchronous line equipment have been designed as D subminia-ture connectors; they are in the connector panel of the application (see Chapter 6.3).

5.1.3 Control and Monitoring by the NCTThe Network Craft Terminal NCT carries out all the functions of the Local Craft TerminalLCT (see Chapter 5.1.2). In addition, the NCT is used for alarm monitoring in networkswith up to 50 network elements.
For a better overview, a map can be displayed on the screen of the NCT as backgroundbitmap on which the relevant network element symbols (icons) can be positioned ac-cording to the geographical locations of the network elements. Interconnections of net-work elements can also be displayed.
Arranged at central points, the stationary NCT is suitable for communicating with all net-work elements (NE) of the monitoring range (see Fig. 5.3) and allows simple and quickaccess to the parameters which can be set. The following basic functions belong to this:addressing, configuring and alarm monitoring.
The NCT therefore offers the following network functions according to ITU-T M.3010:– Fault Management– Configuration Management– Performance Management
Using the NCT represents a practical solution for management tasks (Telecommunica-tions Management Network TMN) in smaller to medium networks as well as for existingnetworks with expansion stages staggered with respect to time. It is particularly suitablefor modern SDH transmission networks with high availability and correspondingly fewalarms.

5.2 Protection SwitchingThe protection switching options realized for SL64 networks currently are as follows:• Linear Multiplex Section Protection: STM-64 Linear-MSP (1+1 or 1:1), STM-16
Linear-MSP (1+1 or 1:1), STM-4 Linear-MSP (1+1), STM-1 Linear-MSP (1+1)• Self-Healing Ring Protection: STM-64 (BSHR-2 combined with MSP), STM-16
(BSHR-2 combined with MSP)• Extra traffic is supported in Linear MSP and MS-BSHR-2 protection schemes.• Path Protection (SNCP)• Card Protection for some modules• Squelch tables for HO squelching in BSHRs according to ITU-T G.841
The following paragraphs give more detailed descriptions of the different types of pro-tection switching with their relevant functionalities.
5.2.1 Module Protection SwitchingTo increase system availability, the following possibilities exist for module protectionswitching:– (1+1) protection switching for the switching network module SNL64-3 and for the
clock pulse supply module CLL64,– (1+1) protection switching for optical modules OIS64 / OIS64-2 (combined with
MSP)– (1+1) protection switching for optical modules OIS16 / OIS16-2 (combined with
MSP)– (1+1) protection switching for optical modules OIS4 / OIS4-2 (combined with MSP)– (1+1) protection switching for optical modules OIS1 (combined with MSP)– (1:n)-protection switching for electrical interface modules EIPS1
(STM-1 / 140 Mbit/s). Example see Fig. 4.15.
Over and above that, the supply voltage feed to the line equipment can be duplicated.
5.2.1.1 Criteria for Initiating the Protection Switching ProcessThe working-protection changeover is triggered automatically by monitoring circuits, butit can also be controlled by the operating terminal or operations system.
Criteria for initiating module protection switching are as follows (for OIS modules seealso 5.2.2.3):• Internal initiation
– Card Failure, CF (module failures: fault in the module power supply, PCU fault,fault in the ASICs, module not plugged in, clock not present)
– Errors in internal signals ISDH, ISU• External initiation
– Forced Switch (changeover via operating terminal/OS)
5.2.2 Linear Multiplex Section Protection (Linear MSP)
5.2.2.1 Linear (1+1) MSPIn the case of (1+1) protection switching, the same data signal is transmitted to two sep-arate lines. One of the two data signals is selected on the receiver side. External protec-

5.2.2.3 Criteria for Initiating the Protection Switching ProcessLinear MSP can either be initiated manually using the operating terminal/OS or automat-ically under the control of the SCU-R2 / SCU-R2E. According to ITU-T RecommendationG.783 there is a hierarchy of priorities in accordance with which the protection switchingprocess will be initiated.
The criteria for protection switching are listed below, starting with the highest priority:• Local initiation
– Forced Switch (switch via operating terminal/OS)– Signal Fail (SF), corresponding to the following error states, e.g.:
Loss of Signal LOS,Loss of Frame LOF,Section-AIS received
– Signal degrade, SD (the threshold bit error rate is configurable; proper configura-tion allows protection switching at bit error rates below 10-6)
• Remote initiation– Changeover of other network elements by remote requests via bytes K1/K2
5.2.3 Bidirectional Self Healing Ring Protection Switching (BSHR)In rings, the same protection switching measures as for line and path protection switch-ing are possible including also bidirectional, self-healing ring protection switching(BSHR). In the case of interference in a multiplex section, the data signal is looped backat the two ends of the disturbed section via the protection line. Protection switchingmechanisms for 2-fiber rings (BSHR-2) have been implemented.
5.2.3.1 2-Fiber Ring Protection Switching (BSHR-2)The BSHR-2 consists of a number of network elements (synchronous line units) forwhich the line interfaces are connected to each other in the form of a ring, with or withoutextra traffic.
Since each line interface is connected to an optical fiber for incoming signals and opticalfiber for outgoing signals, this virtual produces one optical fiber running in the clockwisedirection and one optical fiber running in the anticlockwise direction (“2-fiber ring”).
A path is generally switched in normal mode using the shortest route or so that it willpass through as few network elements as possible. In contrast to other ring protectionswitching mechanisms no transmission capacity is required on the other ring segments.
In the event of a ring segment being interrupted or a fault occurring in a segment theneighboring network elements switch the entire payload signal via the protection path ofthe other segments. In this way the “Working” path of each segment is protected.
To do this half the capacity of the ring must be provided for the protection path.
All segments of the BSHR-2 have the same priority as regards switching over the ring.The switchover mode is revertive and it is possible for the user to configure the wait-to-restore time.
In fault-free state, the protection channels can be used to transmit extra traffic VC-4s. Incase of protection switching, this extra traffic transmission is interrupted.
The figures below show the signal flow for the transmission signal in typical states of theMSP switch control in each case.
Fig. 5.8 shows an example of a 2-fiber ring in fault-free operation.

5.2.4 Card Release Switching (CRS)With Multiplex Section Protection without CRS the data signal of the protection path willbe routed to the SNL64-3 via the working OIS module if a fault occurs (see Fig. 5.5). If,in the worst case, the working OIS module is faulty, this can however lead to signal fail-ure.
Card Release Switching enables expanded Multiplex Section Protection which takes ac-count not only of faults on the transmission line but also of faults on the optical interfacemodules OIS. CRS becomes active when the working OIS module reports a hardwarefault; module SNL64-3 then selects the protection OIS module.
Card Release Switching can be used in combination with (1+1) or (1:1) MSP and withBSHR-2.
Fig. 5.10 shows an example of (1+1) multiplex section protection in “Protection” statewithout effective CRS. The transmission signal was diverted to the protection line, theOIS working module is operating fault-free.

The switch over to the protection path occurs in the “non-revertive” mode, i.e if there wasa switchover to the protection path as a result of a transmission fault, there is no auto-matic switch back to the original path once the fault is rectified, but only if there is a faulton this new path.

Technical Description (TED)
5.3 Supplementary ServicesSignals for supplementary services are transmitted in the Section Overhead. The capac-ity of an Overhead Channel is 64 kbit/s or a multiple thereof. Overhead bytes for user-specific data channels (AUX) and engineering order wire (EOW) channels can be ac-cessed via the Overhead module OHA.
Specific Overhead Bytes can be interconnected via the OHA switching unit by eachSTM-N interface of the line or tributary side to the AUX interfaces. The Local Craft Ter-minal is used for through connection. Telemetry signals (C-AL) can be coupled and de-coupled by using the connector module TIF (via the OHA module).
5.3.1 User-Specific Data ChannelsThe following interfaces are available:• Two bidirectional G.703 interfaces (connected via the OH switching matrix) with er-
ror monitoring for LOS or AIS.
The G.703 interfaces can optionally be used for:– Direct OH access,– Access to telephone conference call or– A TIF interface(These functions are mutually exclusive).
• Four bidirectional data interfaces sV.11 (corresponding to ITU-T V.11, but with otherimpedance) for the connection of data terminals and the through connection of datachannels.
5.3.2 Engineering Order WireThe engineering order wire channels are transmitted via the EOW bytes E1 and E2.
The following interfaces are available:• A 2-wire interface
An analog 2-wire a/b interface to connect a 16-key telephone with DTMF dialing andinternal ringer. Selective, collective and group calls are possible. For selective orgroup call, a three-digit telephone number is allocated to the telephone.Via an external telephone ringer connection, incoming calls (selective call, groupcall) can also be identified if the telephone handset is off-hook or no telephone isconnected.
• Two 4 wire E&M interfaces– for the connection of EOW terminals such as EOW switching, O&M Center
(ZBBeo),– for the transition to other systems such as e.g. Synchronous Multiplexer SMA
(SDH) or OLTS (PDH) in which case the external equipment also has to supportDTMF dialing.
• A PBX interfaceAn analog 2-wire a/b interface for DTMF dialing or pulse dialing is used to connecta private branch exchange or a public exchange.
Telephone Conference Circuit
A maximum of two independent EOW conferences is possible (see On-line Help). Thetelephone conference circuit allows the interconnection of external speech channels
98 A42022-L5907-B51-2-7618
Technical Description (TED) InformationSL64-3.3
(e.g. from “East” and “West” line signals as well as tributary signals; 2-wire and 4-wire)so that each subscriber is connected with every other subscriber.
Correct connection of the EOW channels into a conference or in a ring structure is theresponsibility of the system administrator.
Selective Call, Group Call and Collective Call
3-digit selective, group and conference call numbers are supported in which case thedirectory numbers 000, XY0 and X00 are reserved for collective call and group call (seeOn-Line Help).
5.4 Clock Pulse Supply, SynchronizationFrequency synchronous network operation requires synchronization of all equipmentoperating in the network to a central reference clock pulse.
The following reference signals are suitable as clock pulse sources:– An external 2048-kHz / 2048-kbit/s (via CLA) clock pulse signal T3 which can be ap-
plied at a synchronization input of the multiplexer,– The clock pulse derived from a line or tributary signal,– A clock pulse of the internal quartz oscillator (plesiochronous operation).
The clock pulse of each network element can be synchronized with a very precise clockpulse source (Primary Reference Clock, PRC) according to the master-slave principle.The clock pulse information is distributed via the transport network.
5.4.1 Synchronous Equipment Timing Source, SETSWithin each network element (except for regenerators), the SETS (Synchronous Equip-ment Timing Source) function on the Clock Unit Line (CLL64) module takes care of localsynchronizing.
The signals T1 (STM signals) and T3 (2048 kHz) feed the clock pulse information intothe SETS (see Fig. 5.13). One of the two signals is used as the current synchronizingsource. The SETS function derives the clock pulse T0 from this. Each outgoing SDH sig-nal is synchronized from this T0 clock pulse and T0 is also used as the central clockpulse within the network element.
The SETS function does not only supply the synchronous clock pulse to the moduleswithin the network elements, but also via the T4 interface to other equipment. After asynchronization fault in the transmission line, sections of the transmission range are nolonger permanently coupled to the Primary Reference Source PRC. In this case, theclock pulse synchronization has to be configured anew in the network structure. For this,each SETS can be synchronized with different T1 or T3 sources. When configuring inthe course of commissioning the synchronous line equipment, the clock pulse source tobe used is specified.

InformationSL64-3.3
Technical Description (TED)
Fig. 5.13 SETS Function According to ITU-T G.783
If an existing synchronization with a reference clock pulse source is no longer available,the SETS switches from synchronous operation to the holdover mode.
If the SETS cannot be synchronized with an external clock pulse source, it changes tothe free-running Mode.
In both modes, holdover and free-running, the SETS independently supplies clock pulseT0 from Timing Generator SETG, but with reduced frequency and phase quality. In thiscase, clock pulse T4 is no longer made available because of clock pulse suppressionwhich occurs in that instance (Squelch Function).
5.4.2 Timing MarkerBecause it is possible to choose between clock pulse sources of different precision, it isuseful to transmit information about the quality of the clock pulse used. Otherwise, thereference clock pulse used is selected according to a given priority list.
The Synchronization Status Message is contained in the MSOH of the STM-N signal.For information about the precision of the clock pulse of the signal, six quality steps havebeen specified according to ITU-T (see Chapter 9.5).
5.5 Real Time ClockFor time stamps (time and date) in error and operational messages of the SCU-R2 /SCU-R2E and PCUs, a real time clock is available on the SCU-R2 / SCU-R2E module(circuit section RTC).
The real time clock can be set via the LCT/NCT operating terminal or a network man-agement system.

Laser Shutdown) which automatically takes the laser transmitter of the disturbed sectionout of operation according to ITU-T Recommendation G.958.
In the case of signal failure exceeding 500 ms at the optical receiver of an SL networkelement, the laser transmitter is switched OFF in this equipment for the opposite direc-tion and thereby the disturbed field is taken out of operation. Then the laser transmittercan be switched on periodically every 70 s (for 2 s or 9 s restart pulse length) or for 2 s,9 s or 100 s (configurable). If the receiver of the device concerned again receives a validsignal, the laser transmitter of the opposite direction is again immediately put into con-tinuous operation.
When switching on internal power supplies or after a laser switch-OFF caused by totalfailure of the power supply in the telecommunications center, the laser transmitter(s)must be forced switched ON for approximately 2 s, 9 s or 100 s after the permissibleoperating conditions have been reached.
In the case of line interruption or for maintenance work, the laser transmitter must beswitched ON manually for approximately 2 s or approximately 90 s (test purposes). Thetransmitter is switched back ON via the operating terminal.
5.7 Single-Fiber OperationIt is also possible to operate the SL64 in single-fiber mode with STM-1, STM-4, STM-16,and STM-64 signals. For this purpose, a separate optical splitter is required; however,this increases the attenuation.
To enable the ALS function (see Chapter 5.6) to shut down the laser safely − for exam-ple after a fiber breakage − even in single-fiber mode (rather than being forced into amalfunction state by its own transmit signal) the optical interface must be capable of dis-tinguishing between its own transmit signal and the signal received from the far-end sys-tem. The J0 byte is used for this purpose.
The ALS function should always be enabled in single-fiber mode.

6.1 RacksThe racks used should comply with the dimensions recommended by ETSI (EuropeanTelecommunications Standards Institute): W = 600 mm, H = 2200 mm and D = 200 mm(empty), 300 mm (equipped) (ETS 300 119-3). Fig. 6.1 and Fig. 6.2 show typical equip-ping examples.
The SL64 subrack is secured on the front of the rack. To make fitting easier, there aretwo support lugs in each case which have to be fitted in the points on the front of therack where the subracks have to be installed. The space provided at both sides betweenthe subracks and the rack wall is available for cabling the subracks with one another andthe copper connecting cable of the telecommunications center and the point behind thesubracks is reserved for the FO cables. Each connecting point (connector) can also beaccessed for a cabled rack, e.g. for subsequent equipping without interrupting the line.
The top-most rack slot is used for fitting a terminal panel with the connecting elementsfor the operating point. The terminal panel contains the fuse panels with up to six linecircuit breakers each as well as a module for signaling according to construction practice7R.
The bottom of the rack is open so as to let in fresh air; likewise the top of the rack is openas an air outlet and cable feed-through. Heat is dissipated from the modules by forcedconvection with the aid of a fan shelf.
The rack is secured to a floor rail with pins. Height-adjustable feet can compensate forfloor unevenness of up to 25 mm. Fastening sets are available for fitting under a planarcable shelf. Doors have not been provided for the racks.

The battery voltage (Nominal value –48 V or –60 V) is distributed via the circuit breakersto the power supply connections of the subracks.
For every SL device in the rack, a Medium Attachment Unit MAU can be installed in therack terminal panel if required. This allows the symmetrical QST/B3 interface of the SLequipment to be adapted to the coaxial Ethernet interface of an LAN network for remoteaccess of an LCT/NCT or TMN. The SL equipment can be connected with coaxial cablesvia the MAU (also via several racks).
6.3 Subracks and Equipping
6.3.1 Subrack SL64The double-row subrack SL64 (Fig. 6.3) is the universal subrack for equipping as syn-chronous add/drop multiplexer, synchronous line terminal or local cross-connect. Re-configuration is possible at any time by simply exchanging modules, even subsequentlyduring operation.
The subrack contains, from top to bottom:– a connector array for the power supply (working/reserve) of subrack and Fan-shelf;– slots for 142 mm high interface modules;– an alarm panel with LED displays and connector panel for service/operating inter-
faces;– slots (single row and double row) for 565 mm and 265 mm high transmission mod-
ules plus control and clock modules.
The SL64 subrack has the following plug-in slots:– 16 tributary (OIS(N), OIS(N)-2, EIPS1, ETH100/1000) and/or booster and/or pream-
plifier cards– 2 tributary protection and/or booster and/or preamplifier cards– 2 x CLL64 / CLL64-2– 2 x SNL64-3 (double height card)– 2 x OIS64 / OIS64-2 (double height card)– 1 x OHA– 1 x SCU-R2 / SCU-R2E
The subrack is basically intended for fitting in an ETS rack, it cannot be mounted in a19-inch rack.
Heat is dissipated by forced convection with the aid of a fan shelf built into the rack.
The cable connections for internal rack and telecommunications center cabling are ar-ranged on a terminal panel in the middle of the subrack and can be accessed from thefront (see manual ITMN).
The rack cabling needed for commissioning the rack is described in the Instal-lation and Test Manual, ITMN.

These addresses clearly specify the identity of the synchronous line equipment.
7.5 Log RecordsIt is not mandatory for the equipment of the network element SL64 to be permanentlyconnected to an operating terminal or a network management system for continuousalarm monitoring. All currently occurring, urgent and non-urgent alarm messages arestored in the SCU-R2 / SCU-R2E. All the events which have already been acknowl-edged (“acknowledge”) are recorded in log records.
After an operating terminal or a network management system has been connected, theuser can interrogate the stored events or alarms.
The following log records are recorded:• NE logs
The NE stores the last 100 alarm events / History Events and the last 100 configu-ration settings / Configuration Events. New events which occur always overwrite theoldest entries.
• NE startup logContains clear text information to a preceding NE start:Up to ten items of fault information or the note “No faults”.
• Subrack logsHere there are three different Log Record Types which are generated during NEstart and are used only by service personnel of the manufacturer for diagnostic pur-poses.

software components as for SL64 (see Fig. 7.4). For all network elements of the secondSDH generation there are corresponding SW components.
The modular software concept of the NCT makes it possible to integrate the network el-ement-specific software components needed for a specific network configuration into anoverall package.
For future expansion with additional network elements, further software componentscan be added at any time.
Fig. 7.4 Product Architecture of the NCT
Features• Display of all the NEs in the monitoring range and their operating/alarm states as a
graphical network overview.• Separate access to each NE in the monitoring range.• Displaying the performance data of any NE from the monitoring area.• Collecting alarm messages arriving from the NEs (Alarm History).• Fault diagnosis for an NE alarm to be carried out by a central point.• Configuration changes which are easy to make via the NCT at any NE facilitate the
quick and cost-effective provision of new services.• The size of the monitoring range can be adapted flexibly to the requirements of the
network operator.• Standard platform supported by Windows embedded in a Microsoft-based SW en-
vironment.• A common operating software integrates all the network element types of the sec-
ond SDH generation in the management system.• Graphical user interface adapted to other Windows applications and therefore no
computer-specific user training is required.• Five user classes ensure high access security; user identification and password are
used for access control.• Software download and software upgrade can be carried out centrally for any NE in
the network.• Simultaneous monitoring of up to 150 network elements.

8 Commissioning, Operation and Maintenance
8.1 CommissioningThe synchronous multiplexer SL64 has to be configured on initial commissioning. Forthis purpose, a Local Craft Terminal (LCT) has to be connected to the QST/F interfaceof the SL equipment. The hardware and software requirements at the craft terminal aredescribed in Chapter 5.1.2.1. The craft terminal offers a graphical, menu-driven user in-terface.
8.2 Operation
8.2.1 Operating Devices of the SubrackOn the terminal panel of the subrack there are two switches to configure the impedanceof the system clock pulse (75 Ω unsymmetrical or 120 Ω symmetrical).
In the Subrack Alarm Panel SRAP-PI of the SL64 equipment there is an acknowledgekey RT for manual acknowledgment of the Bw7R alarm messages (see Chapter 4.6).
8.2.2 Operating and Display Elements of the Modules
LED Displays of the Modules
Especially to assist in maintenance work, there is a red fault LED (INT) and (except forLTU module) a green service status LED (ID) on the front of each module which are vis-ible after the subrack cover has been removed (see Fig. 6.4).
The type of display is explained in detail in Chapter 5.1.1.1.
Operating Elements of the Modules
No hardware settings have to be made on the printed circuit boards of the module. Themodules are configured by software commands which are relayed to the relevant mod-ule via the SCU-R2 / SCU-R2E and originate from the operating terminal LCT or NCT(or from a network management system) when commissioning or in the case of laterchanges.
On the front of the TIF module there are two switches to select the 64-kbit/s channels(see Chapter 4.5.5.2).
Detailed information for commissioning the synchronous multiplexer SL64 andthe operating terminals is given in the Installation and Test Manual, ITMN.
Operation of the synchronous multiplexer SL64 is explained in the OperatorGuidelines, OGL.
Setting the switches is described in the Installation and Test Manual, ITMN.
Operation of the Subrack Alarm Panel SRAP is explained in the OperatorGuidelines, OGL.
Help Configuration of the modules using software is explained in the On-Line Help.

Technical Description (TED)
8.2.3 Operation with an Operating TerminalFor local or remote control and monitoring of each SL device, a Local Craft TerminalLCT can be connected (see Chapter 5.1.2). It communicates with the system control unitSCU-R2 / SCU-R2E of the synchronous line equipment. It is connected via an internalcommunication system to all the Peripheral Control Units PCU in the SL equipment.
The Local Craft Terminal LCT is permanently allocated to the local network element.
Organizational relationships between the synchronous line equipment in the network(network elements) are only available via the Network Craft Terminal NCT and not viathe Local Craft Terminal LCT (see Chapter 5.1.3).
8.3 Maintenance
The alarm and maintenance concept of the system provides sufficient alarm informationto localize and clear the fault at module level. The equipment has been designed in sucha way that no regular settings are required.
Maintenance measures (e.g. fault localizing) can be carried out locally via the operatingterminal interface QST/F (LCT/NCT) or under remote control via the QST/B3 interface(LCT/NCT or a network management system).
The functioning of the switches is explained in detail in the Installation and TestManual ITMN.
iThe Local Craft Terminal LCT is needed only for commissioning, configuration changesand maintenance of the synchronous line equipment. The LCT is not absolutely neces-sary for ongoing payload data transmission in the synchronous line equipment and canbe removed (provided that it is not to be used for alarm monitoring and quality monitor-ing).
Help
The maintenance of the SL64 is described in the OGL and in the On-Line Help.
