1 Introduction

1.1 GeneralThis manual, NM:LTG, contains information which is intended to support nonstandardmaintenance in the event of LTG faults.An LTG hardware fault can normally be cleared with the aid of the procedures containedin maintenance manual MMN:LTGx. The Nonstandard Maintenance documents for LTGare not needed in any of these cases.Only if the aforementioned procedures are unsuccessful is it necessary for a systemspecialist to carry out fault clearance. To assist the specialist, NM:LTG contains addi-tional information on each type of fault, for example: Interpretation of hexadecimal additional information from the result printout Brief description of the safeguarding sequence which resulted in the system mes-

sage A list of system responses A list of suspect hardwareTo facilitate document management, the supplementary documents for all LTG typeshave been put together in this manual and arranged in ascending order. For LTG fault reports: MMN:LGxxx-zzzz

zzzz is the search word for the range LTGzzzze.g.: MMN:LG001-0036 information under LTG0036

For diagnosis progress messages: FLN:LTGxxxe.g.: LLN:LTG036 information under FLN:LTG036

1.2 References to Additional Documentation Of particular importance for Nonstandard Maintenance is the manual Construction;

Section Racks offers an overview of the equipment containing LTG frames and thefuse assignments. Section Frames LTG provides the layout of LTG frames and ca-bling according to cable list. The interpretation of the LEDs on the module face-plates, settings of the DIP-FIX switches and the location of the solder pins is givenin section Modules.

The Documentation Overview contains detailed information on all general aspectsof fault clearance.

When replacing or handling modules please observe the Safety Instructions for per-sonal and products (EN60950/IEC60950).

1.3 Functions Groups LTGIn order to save space and energy, and to enhance reliability, the functions of severalolder modules are to an increasing extent being integrated on a single new module. Forthis reason, the following sections refer to functional groups, except where a module isspecifically referred to. Depending on the LTG type, a functional group can be identicalwith a module or it can be implemented together with another functional group on a mod-ule.Modules used for the Function Groups in the LTGs

gg: user: AAH = fault detected by safeguarding FFH = fault detected by routine test

hh: cause of error: 81H = over 50% of the speech channels are faulty

Description:The functions of the LIU functional group and all 127 LIU channels to the GS are testedduring diagnostics (channel 0 is not tested).The first channel is seized for the test and the GS loop-around is strapped. After theloop-around is strapped in GS, a cross office check (COC) is started. If the COC is suc-cessful the test for this channel is ended and then the next channel can be tested. If theCOC is unsuccessful it is repeated. If the fault is confirmed no information can yet beissued whether the speech channel or the (TPAEC) test pattern evaluation circuit isfaulty. A new test procedure is therefore started for fault localization.The test connection is switched through from the SIB to the SMX and from there to theGS via SPHI 11, channel 27; then to the LIU via the LIU channel of the SPHOL to betested. The connection continues through an internal LIU loop and on to the GS alongthe LIU channel of the SPHIL to be tested; then to the SMX via SPHO 11, channel 27and from there back to the SIB.

Fig. 2.1 Test configuration of the LIU channel test

Test patterns are sent from the SIB to the LIU along the through connection, which re-turns to the SIB via the internal LIU loop. The GP compares the test patterns sent withthose received. The following test patterns are sent and expected back: 00H, 55H, AAH,66H, 99H.If the test patterns received are not the same as those sent, the LIU channel will be test-ed once more. If the second test is also faulty, the LIU channel is marked as defectiveWhen all LIU channels have been tested, a count is made of all the LIU channels markedas defective. If 64 or more LIU channels were found to be defective, the followingprogress message is output: LIU TOTAL FAILURE

Description:The functions of the LIU functional group are tested during diagnostics. The test patternevaluation circuits (TPAEC1-3) and the LIU channels are tested. Test LIU Channel

All 127 LIU channels to the GS are tested during diagnostics (channel 0 is not test-ed).The first channel is seized for the test and the GS loop-around is strapped. After theloop-around is strapped in GS, a cross office check (COC) is started. If the COC issuccessful the test for this channel is ended and then the next channel can be test-ed. If the COC is unsuccessful it is repeated. If the fault is confirmed no informationcan yet be issued whether the speech channel or the (TPAEC) test pattern evalua-tion circuit is faulty. A new test procedure is therefore started for fault localization.A through-connection is then made from the signal buffer (SIB) via the GS to the LIUand then back again. The speech channel is then looped back to the LIU. Five testpatterns are transmitted. If the transmitted test patterns are identical to those re-ceived, there is a TPACE error (cause of error 83H) and there is a progress mes-sage:LIU PARTIAL FAILURE

Testing of the test pattern evaluation circuits (TPAEC1-3):The test comprises two test steps: testing for positive response

The test is started when 0000B is output to the LIU control memory. The multi-plexer MUX4 is switched to the input TP. The test patterns are fed in at the input

and sent to the GS, looped back and lead to the LIU again via an idle LIU channel.They are received by the test pattern evaluation circuit TPAE3 on the LIU. The testpattern sent also reaches the test pattern evaluation circuits TPAE1 and TPAE2via two internal test loops. The test pattern sent must be the same as that re-ceived. The test pattern evaluation circuits TRAE1.3 should not report a fault. Ifno fault is found during the test for positive then a test is made for negative.

testing for negative responseThe test is started when 0001B is output to the LIU control memory. The multi-plexer MUX4 is switched to the input TPX and a falsified test pattern is sent viathe same LIU channel for the same GS setting. The test pattern evaluation circuits(TPAE1.3) must report a fault as a result of the falsified test pattern.

Fig. 2.2 Test configuration of the test pattern evaluation circuits

If a fault is detected during one of the test steps, the test is repeated using the next idleLIU channel. If the fault is confirmed, a progress message containing the following code-word is output: LIU PARTIAL FAILURE

Description:This progress message is output in two cases:1. The speech memory cells of speech highway 11 are tested via a loop from ORAM

to IRAM via channels 26, 25 and 27.Between the individual test steps of the double connection test various test bit pat-terns are sent via channel 26. These test bit patterns generate FIFO events for thesechannels depending on the connection:Test step 01 SPH11/CH26 -> SPH11/CH27 with DC check,Test step 02 SPH11/CH26 -> SPH11/CH25 with DC check,Test step 03 SPH11/CH26 -> SPH11/CH25 without DC check,After all test bit patterns have been sent, the bit patterns received are compared withthose sent.In the first and third test steps, the bit patterns must be the same. In the second teststep, they must not be the same, because these connections have not been set up.If there is a fault, the test is canceled and the following progress message is output:GS TOTAL FAILURE

2. During LTG diagnostics, the 512 control memory cells of the GS are tested.Commands and data are sent from the GP via the ORAM to the GS control via theSMX channels 16...19. Before the test is started, the LTG is configured to a specialstate to suppress the FIFO service and timer processing, so that testing is possible.The periphery and all IRAMs not needed for the test are blocked.After these preparations all control memory cells are loaded with their own addres-ses. After loading, commands are sent to the GS control via the SMX channels16...19 to read out the control memory cells again. The commands generate FIFOevents for these SMX channels. The data are read from the FIFO and compared withthe reference values. If they are not the same, i.e. control memory cell defective, acounter is incremented.If 50% (256) of the control memory cells are defective, the test is canceled and thefollowing progress message is output:GS TOTAL FAILURE

If no fault is detected, a second run is started, in which the control memory cells are load-ed with the inverted control memory address.

hiikkllmmnnoopp: bitmap of the defective conference cells0 = no fault1 = faulty

Description:For an LTG with conference circuit, the 64 conference cells of the GS are tested duringLTG diagnostics.During diagnostics, a connection with channels 25, 27 and 28 of speech highway 11 isset up twice for every conference cell. If the GS setting was carried out successfully anda bit pattern is sent via the connection. The sum from the connection is compared witha reference value. The reference value depends on the LTG type, the conference typeand conversion (u-low, A-low).If a fault is detected (defective conference cell), the same conference cell is retested. Ifthe fault is confirmed, the conference cell found to be defective is marked in a data field(SACONF) which is evaluated at the end of the test. If 50% or more of the conferencecells are found by the diagnostics to be defective, the following progress message is out-put:GS CONFERENCE TOTAL FAILUREIf less than 50% are defective, the progress message is:GS CONFERENCE PARTIAL FAILURE

Description:The SMX test can be executed only if the LTG is in diagnostic state. The test has 10 teststeps.1. Test step1:

In test step 1, the memory for the last look setting is tested. SII 1 is activated(SII = 1). For all IRAM channels, FFH is output and the inhibit bit is set. FFH is outputto all ORAM channels. The loop is removed from the PU so that the SMX can betested. The SIB input block must be canceled for the same reason.The inhibit bits for the SMX channels 31 in frames 0...15 must be reset so that thememory for the last look setting can be tested. 55H is output in turn to the SMX chan-nels 31 in frames 0...15.In the following cases a progress message is output and diagnostics are canceled:- no FIFO event- the SMX address under which the FIFO event came is incorrect- NEW DATA is not 55H

Test step 2:In test step 2, the memory for the last look setting is tested.AAH is output in turn to the SMX channels 31 in SMX frames 0...15.In the following cases, a progress message is output and diagnostics are canceled:- no FIFO event- the SMX address under which the FIFO event came is incorrect- NEW DATA is not AAH

3. Test step 3:

After SII has been deactivated (SII = 0), the FIFO events are checked to see whetherthe correct data item is under the correct SMX address. If this is not the case, aprogress message is output and diagnosis are canceled.

4. Test step 4:In test step 4, the loop function and the multiplexer are tested.For all SMX channels 31 of SMX frames 0...15, FFH is output (IRAM) and the inhibitbit is set (inhibit bit RAM). 80H is output to the SMX channels 31 of SMX frames0...15, so that the SMX module, and with it the loop function, can be tested.Meaning of the 80H in the memory for the last look setting:

Description:A switching logic of the functional group GCG selects one of the clock pulses from theLIU coming from SN side 0 or 1. If the module GCG:LTGY is used, these are CLK0 orCKL1 and SYNI0 or SYNI1, otherwise SYNI0 or SYNI1.The choice of clocks depends on which SN or which TSG is active at the time. The SYNIclock chosen is fed to the phase locked loop (PLL).The phases of the SYNI clock (8kHz) are compared in the phase discriminator withthose of the clock CKS (8kHz) derived from the VCO. If the phases of the two 8kHzclocks differ by more than 244ns, a PLL alarm is signaled from the PLL supervision cir-cuit via line SCI1 and the SMX module to the PU. The peripheral event "PLL ALARMACTIVE" is sent to LTG safeguarding and procedure SAFCLPLA is entered.When the 8192kHz clock CKL fails, PLL supervision is blocked. When the clock is start-ed the two 8kHz clocks (SYNI, CKS) are not synchronous. For this reason, PLL super-vision is blocked for a further 3.8us when the clock is started. Within this time the clockscan synchronize themselves.If a PLL alarm is signaled during LTG diagnostics, a progress message is output withthe following codeword:PLL 30 ALARM (CLOCK 0)
