TRAU Congestion identification

[electron]

Hi friends,


We observed TCH drop reason due to other reason for huge amount of cells.We have asked transmission team to check they claimed every thing is ok in their side. So we suspected for TRAU .Is there any counter or a trick to identify TRAU problem(congestion or etc.)


Thanks,

use the counters in the BO..TPCONG is for transcoder congestion.

Thanks. I could not to find this counter in Statistics document .What is your idea about using TNRELCONG counter to identify this issue?

TPACC Number of accumulations
TPACTTR Active Transcoder Resources
TPAVTR Available Transcoder Resources
TPIDLTR Idle Transcoder Resources
TPALLOC Transcoder Resource Allocation Attempts
TPCONG Transcoder Resource Congestion
TPCTIME Transcoder Resource Congestion Time
TPSYNCF V.110 Synchronization Failure for pooled transcoder devices
TPTFOESTATT Number of TFO establishment attempts

you can search in the alex...

Also check you have the correct values for SAE especially RTTPH & RTPDI SAE=500, if the TRAU is in the BSC.

ALso check connection type is correct (half/full-rate)

Check for route congestion eg on MALT devices.

Also check if there is a conn_fail message with cause h'28 on Abis (remote tc alarm) and CLR_REQ cause h'20 (Equipment failure) on A.

Hope this is helpful...

Please use this.Just modify the SQL script to meet the table you have in the ENIQ/Sybase


SELECT date_id,elem,trc,hour_id,TPACC,TPACTTR,TPAVTR,TPALLOC,TPCONG,TPCTIME,((TPACTTR/TPAVTR)*100) as UTILI

FROM DC.DC_E_CMN_STS_TRAPEVENT_RAW where hour_id between 19 and 21
and date_id>='2010-10-1'
order by UTILI DESC

Have you checked stat of DIP? make sure not the transmission problem.
check count per DIP (RBLT, RTB, RALT) of Error second (ES), Slip Frame(SF), ESR, UASR, etc on BSC and TRC.
