    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.

    1. Congestion:
    too many com => Add TRX

    2. Channel failure:
    check TRX, BB2x, copler and feeder

    3.excessice interference:
    change TRX or BB2x

    4.traffic channel
    change TRX or BB2x

    I told you a mistake about 4.Traffic channel

    Traffic channel is a bad declaration of sdcch.

    example:

    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.

    7725 TRAFFIC CHANNEL ACTIVATION FAILURE
    02

    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.

    Thx

    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
