1 Introduction (IN)

If you are familiar with the basic principle of the fault clearance described in this manual,you can start with fault clearance at once (Register PROC).Otherwise we advise that you read this register in order to be able to use the manualeffectively for fault clearance purposes.Detailed information can be found in the appendix (APP)

1.1 Interfaces of MMN:LTG

The following diagram shows the points of entry to MMN:LTG, its structure, and theother manuals to which reference can be made.

Key to the interface diagram

Register IN describes how to use this manual.

Register PROC contains the fault clearance procedures.

Register TAB gives an overview of the allocation of the module frames to the fuses andthe layout of the modules in the module frames.

Register APP describes fault reports, state interrogations, configurations and diag-noses.Entry can take place in the following ways:

1.2 Guidelines

The fault clearance procedures in this manual serve to locate modules that aresuspected of being faulty in a remote or local exchange. The modular structure of theLTG enables the maintenance personnel to clear a large percentage of faults in thesystem by locating and replacing faulty modules. The suspect modules are removedmanually and replaced in the exchange with spare modules.

The following steps summarize the general procedure for locating and clearing faultswith the aid of this maintenance manual:

1. A fault is discovered by routine tests or system supervisory circuits.

2. The MMN number of the fault message serves as the entry into the appropriate faultclearance procedure in Procedures (PROC) of this manual.

3. Using the relevant procedure the maintenance personnel can locate the fault on siteor from the central OMT by carrying out the steps described in the procedure.

4. The maintenance personnel on site locate and replace the faulty module manually.

5. Faulty modules must be properly marked (electrostatic-sensitive components) andpackaged for transportation to a repair workshop.

The fault clearance procedures in MMN:LTG are usually adequate for clearing most ofthe faults that can occur in the LTG. However, if all suspect modules have already beenreplaced and the fault still occurs, or if diagnosis has not revealed the cause of the fault,the next fault clearance level (TAC1 ->TAC2 ->TAC3) must be consulted in order toobtain additional information and means of fault location and clearance.

1.3 Example

The following example shows how maintenance manual MMN:LTG is used for clearingan LTG fault.

The example uses MMN number LG001-0006

Entry into fault clearance

The MMN number LG001-0006 is displayed with the identifier GS TOTAL FAILURE:

Maintenance Access MMN:LTGG:D900

Fig. 1.3.1 Fault message with MMN:LG001-0006

Determining the fault clearance procedure

The MMN number in the fault message determines which procedure is to be used forfault clearance. In this example procedure LG001 in Register PROC must be used tostart fault clearance.

Locating the fault

The fault location line in the fault message contains the logical address of the faultyequipment unit, e.g.:

tsg = number of the switching network time stage group TSG (0...7) to which the LTGreporting a fault is connectedltg = number of the LTG reporting the fault (1...63)With the aid of these parameters the physical address (room number, rack number etc.)can be found in the system-specific documents.

Notes on module replacement:

• Precautionary measures for electrostatic-sensitive componentsAll modules are equipped with electrostatic-sensitive components (ESD symbol).For this reason the precautionary measures for electrostatic-sensitive componentsmust be observed when extracting and inserting modules.When replacing modules, the maintenance personnel must wear a conducting wrist-strap to discharge static. Before modules, leads or components are touched, thewrist-strap must be connected via a flexible lead to the ground potential of the rack.It is important to note that the conducting parts of the banana plug must not betouched while the lead is being plugged in (bridging of the leakage resistance).Further information can be found in the brochure “Safety Instructions for Personneland for Products as per EN 60950” (A30808-X3008-X280-*-7619).

• Extracting and inserting modulesWhen replacing modules it is essential that the special tool provided (C39300-A195-C70) should be used both for extracting and for inserting modules.Faulty modules that have been removed must be marked as faulty, and they mustbe handled just as carefully as new modules.For transportation to a repair center the faulty modules must be marked and packedin accordance with the precautionary requirements for electrostatic-sensitivecomponents.Further information can again be found in the brochure “Safety Instructions forPersonnel and for Products as per EN 60950” (A30808-X3008-X280-*-7619).

• Replacement modulesThe replacement module must be identical with the original module (same codenumber both for HW/FW and for functional status). In exceptional cases theFunctional Level List can be used to determine whether the functional status of thereplacement module (as regards HW/FW) is compatible with that of the originalmodule.If there are switches or other control elements on the module, they must be set asthey were on the extracted original module.

MMN:LTGG:D900 Maintenance Access

1. Conditions:If the air-conditioning fails, it is possible for the temperature to become so high thatthe equipment is destroyed.This can be avoided by the following:

– A warning on the SYP when the allowable temperature is exceeded

– Shutting off of DCCs in the LTG frames via thermal switch before the criticaltemperature is reached

– Central units are not switched off, so that a restart is possible

2. Implementation:In every LTG rack, a thermal switch (F1) is built into the bottom panel of the rack.The contact is fixed at the allowable room temperature. If this temperature isexceeded, then, via this thermal switch all DCCs in the rack receive ground potentialvia the individual control input.

In this way the DCCs are switched off.

If the temperature goes down, the DCCs are switched back on. The LTGs must bebrought back in to service either individually via configuration command or automat-ically via system recovery.

5.1 Safeguarding

The LTG safeguarding functions consist of:

• routine test

• constant self-supervision

• traffic-dependent self-supervision

5.1.1 Routine Test

Routine LTG testing, in which central and decentral LTG modules are tested, isperformed approximately every 2 to 3 minutes. The test sequence is as follows:

TestAbbreviation

Test

RAM Test of the PMUx:- ATM register write/read- 2.5 MHz timer- EDC chip- One-bit error counter- One-bit error statistic- Storage cell check

GCG Test of the PLL supervisory circuits in module CGSM

SPS Test of the GS supervisory circuitsThrough-connection test via SPH11Conference cell test, when conference is created.

LIU Test of a LIU channel (if one LIU channel is found to be faulty, allchannels are tested) and test of test pattern evaluation circuit(TPAEC1-TPAEC3) on module GSL

TOG Test of the tone generator- test tones, idle tones and software windows

5.1.2 Constant Self-supervision

Constant self-supervision is carried out by the supervisory circuits in various LTGmodules, e.g.

• supervisory circuit for frame synchronism

• supervisory circuit for clock failure

5.1.3 Traffic-dependent Self-supervision

Actions triggered by call processing programs are monitored by supervisory circuits,e.g.

• supervisory circuit for setting errors

• supervisory circuit for COC errors

5.2 LTG Fault Printouts

If a fault is detected in the LTG, it is reported to the FA:LTG (fault analysis for LTG) inthe CP. The fault printout is entered in the alarm file (AM.ALARM) and, according to thefault priority, an alarm is signaled on the system panel and/or a fault printout is output.The various fault printouts are described below.

5.2.1 LTG Failure with Configuration

The fault printout LTG failure with configuration is output when the fault is so serious thatthe LTG was taken out of service.

5.3 PCM Fault Printout

A PCM fault printout is output when a PCM fault was detected on an interface modulefor the connection of PCM links (e.g. DIU30D or SLMX). The start and end of the faultare reported.

5.3.1 PCM Fault Start Report

In the case of PCM fault start reports a distinction must be made between maintenancealarm and service alarm. A maintenance alarm is involved if, for example, loss of framesynchronism or a missing input signal is detected for the incoming PCM link.Service alarms are fault reports from the distant exchange or from route equipment.

In case c)Configuration from MBL to ACT. When an LTG goes into service again after fault clear-ance, in many cases the code is not destroyed, or only partly so. It is therefore sufficientto load the destroyed code. The summation check is used to test that the code is correct.This configuration procedure is called “conditional loading”.

If the LTG was reset in the course of fault clearance, it has to be reloaded because reset-ting formatted the memory.

This loading procedure can lead to different configuration command execution times.

5.6.2 DIU Configuration

The DIU must be MBL for fault clearance. If the DIU to be cleared is not MBL, it must beconfigured to MBL before fault clearance. If the DIU is ACT, it should be configured firstto CBL and then to MBL. When the DIU has been successfully cleared of faults it shouldbe configured back to ACT

5.6.3 CR Configuration

Since the CR (Code Receiver) is diagnosed module by module, it is also configured onthis basis for fault clearance.

In the LTGG, two CR4 modules have been compressed to form a CR8 module. Thismeans that two commands have to be entered in order to configure a CR8 module.

In the case of the LTGG in C mode, mod 0 and 1, and 4 and 5, in the SU are combinedon the CR8 module.

In the case of the LTGG in B mode, mod 0 and 1 in the SU, mod 0 and 1 in the LTU 4,are combined on the CR8 module.

Input:

For CR in SU:

CONF CR:LTG=tsg-ltg,CRPOS=mod,OST=xxx;

For CR in LTU:

CONF CR:LTG=tsg-ltg,LCPOS=ltu-mod,OST=xxx;

Explanation:

• LTG=tsg-ltg

• CRPOS=mod

• LCPOS=ltu-mod,

• OST=xxx

State transitions:

tsg = Number of SN time stage group TSG (0...7) to which the LTG isconnected

ltg = LTG number (1...63)

mod = Number of the module within the SU

ltu = LTU number

mod = Number of the module within the LTU

Maintenance Access MMN:LTGG:D900

The LTG must be put into operation to execute the LTG diagnostic. The LTG is con-figured to ACT with the command DIAG LTG first of all, and SEZ (seized by diagnostic)is entered as the operating state.

When an LTG goes into service, in many cases the code is not destroyed, or only partlyso. It is therefore sufficient to load the destroyed code. The summation check is used totest that the code is correct. This configuration procedure is called ’conditional loading’.

If the LTG was reset in the course of fault clearance it has to be reloaded because reset-ting formatted the memory.

This loading procedure can lead to different times for the LTG diagnostic.

5.7.2 DIU Diagnosis

DIU diagnosis must be performed in the following configuration:

• LTG in ACT or CBL

• DIU in MBL

The DIUs are diagnosed individually.

Input:

DIAG DIU:LTG=tsg-ltg,DIU=DIU;

5.7.3 CR Diagnosis

CR diagnosis must be performed in the following configuration:

• LTG in ACT or CBL

• CR in MBL

CR1 Code receiver test for MFC:R1

CR2 Code receiver test for MFC:R2

Several progress reports may be output during LTG diagnosis.Fault clearance should always be continued with the progress message that was printedout first.

5.8 Module Replacement in the LTGG

Specific rules have to be observed for module replacement in an LTGG.These rules depend on whether the module concerned is a current converter module ora module of the central or intermediate-level area of the LTG.

5.8.1 Current Converter Module Replacement

• Configure LTG to MBL

• Switch off current converter module

• Unscrew appropriate fuse of the LTG

• Pull current converter module (Caution: Module is hot)

• Plug in new current converter module and switch off

• Screw in appropriate fuse of the LTG

• Switch on current converter

• Before activating, start diagnosis of the LTG (DIAG LTG)
