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)”
IN Nokia system Traffic channel Activation failure is major alarm on Trx Level and Time Slot level. We have find out some ways to resolve this issue.
1. Check your Trx or Timeslots.
2. Check your E1 configuration against Trx.
3.Check your MO ans MS.
4.check your BCC and TSC. if your BCC and TSC are not same. Then might be possible this alarm can be generate.
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
