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.

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.

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:

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.

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.

CR diagnosis is performed module by module.
In the LTGG, two CR4 modules have been compressed to form a CR8 module. Thismeans that two command inputs are necessary in order to test 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 4are combined on the CR8 module.
Input
For CR in SU:DIAG CR:LTG=tsg-ltg,CRPOS=mod;For CR in LTU:DIAG CR:LTG=tsg-ltg,LCPOS=ltu-mod;
5.7.4 COU Diagnosis
COU diagnosis must be performed in the following configuration:
• LTG in ACT or CBL
• COU in MBL
The COUs are diagnosed individually.
Input:
DIAG COU:LTG=tsg-ltg,COU=cou;
5.7.5 OCANEQ Diagnosis
OCANEQ diagnosis must be performed in the following configuration:
• LTG in ACT or CBL
• OCANEQ in MBL
Input:
DIAG OCANEQ:LTG=tsg-ltg,OCNO=ocno;

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)

5.8.2 Module Replacement in Central Area of LTGG
The central modules of the LTG are:CGSM, GSL, PMUx, SILCB and TOG
• Configure LTG to MBL
• Pull the module
• Insert replacement module
• If module CGSM or PMUx was replaced, the LTG must be reset.
• To reset, press the reset key on the PMUx module
• Before activating, start diagnosis of the LTG (DIAG LTG)
5.8.3 Module Replacement in the Intermediate-level Area of the LTGG
The intermediate-level modules in the LTG consist of the modules in LTUs and in theSU (except for the TOG).
• Configure the relevant equipment (DIU, COU, CR, OCANEQ etc.) to MBL
• Pull the module
• Insert replacement module
• Before activation, start the appropriate diagnosis (DIAG DIU etc.)
