    IF you have BCCH missing, your TRX is OFF.

    many reason:

    Transmission PCM: You have BCCH missing on all TRX with PCM failure.

    TRX is out: bcch missing + lap D failure

    Ross feeder is bad: bcch missing + tx antenna performance degraded

    Bad TRUA: your trame is not good, check routing Time slot. (only after operation)

    After a reset site, you have Bcch missing during a short moment.

    hi patrick and other all,

    Transmission PCM: You have BCCH missing on all TRX with PCM failure.

    TRX is out: bcch missing + lap D failure

    Ross feeder is bad: bcch missing + tx antenna performance degraded

    HOW can resolve those problems?

    HOW? strange question?!

    If you have alarm => you have a problem so you must resolve it.

    => Change TRX, Copler, ODU, cable, … It is curative maintenance.

    Alarm give an indication to find your failure.

    BCCH MISSING = SECTOR (BTS) CUT.

    => There is no MBCCH which is OK.

    Hello,

    I think you should do your homeworks by yourself…

    Hi Anshuman,
