    Possible causes
    DXU Faulty
    TX / RX reversed at BTS
    CRC value incorrect

    Can be a few things
    There is no connection to the TRX in the BTS
    The CF cannot communicate with the TRX
    Are the RXOIS and RXOCON working
    ABIS connections correct ?

    Not in Local mode ?

    Hi,

    Similar Problem i am also facing…TRU is going in fail mode, MO fault description is Permanent fault and Bus fault in few cases.

    we observed this alarm in 2204 BTS and 2964 BTS aswell.

    in 2204 BTS, we changed the BTS s/w from R25E to R22F and found that issue got resolved permanently ( haven’t repeated from 1-2 months)

    But issue is repeating in 2964 cabinet.

    I are facing an issue wherein CF ,TF is operational But RXOIS does not come up resulting in All trx to remain down.

    Can you plz help.

    No DIP Errors found,
    This is happening when a site goes down, when it comes back One sector remains down.

    We have recently Implemented ABIS over IP for this RBSC.
