CHECK If EXCESSIVE TCH INTERFERENCE ALARM IS ON ALL THE TRX, IF YES CHANGE BOI CARD, IF ONLY ON ONE TRX, I THINK IT SHOULD BE ON BCCH TRX, CHANGE THE BCCH.25th January 2008 at 21:10 #50602patrick.frGuest
too many com => Add TRX
2. Channel failure:
check TRX, BB2x, copler and feeder
change TRX or BB2x
change TRX or BB2x25th January 2008 at 21:42 #50603patrick.frGuest
I told you a mistake about 4.Traffic channel
Traffic channel is a bad declaration of sdcch.
with 1 TRX, you declare MBCCHC (C=combined=1 TS for SDCCH and MBCCH)
with 2 TRX, you declare MBCCH (1 TS for BCHH and 1 TS for SDCCH)
If you declare MBCCHC with 2TRX then you have alarm Traffic channel activation failure.28th January 2008 at 13:29 #50604DuleGuest
7725 TRAFFIC CHANNEL ACTIVATION FAILURE
We have this alarm on GP channel.
“2” indicates “PDTCH” (Packet Data Traffic TCH).
We are using 0-TS for BCCH and TS-1 for SDCCH.

Hi Mr. Patrick.fr
I am having a doubt. Is it possible for a sector having two BCCH TRX as you said. I can’t understant.
” with 1 TRX, you declare MBCCHC (C=combined=1 TS for SDCCH and MBCCH)
with 2 TRX, you declare MBCCH (1 TS for BCHH and 1 TS for SDCCH)”24th December 2009 at 10:30 #50606kapilGuest

2. Check your E1 configuration against Trx.

In our network we are facing excessive TCH interference alarm in all most all the sites. While using the spectrum analyzer, we found the high interference in high AMSL. If someone can let me know how to resolve the issue.
Note: We find the high interference in high AMSL whenever there is alarm in BSC
