    Hi Jack,
    check TCUC, reset corresponding TCUC. If it doesn’t help do the BTS commisionning and maybe you should change the SUM card (I don’t know what’s the name for SUM card in Nokia BTSs).

    Hi Jack
    It seems there is a problem in the slot of TRX 6.,change the back plane of the BTS & check.Hopefully your problem will be resolved.

    Also check if the TSC for the TRX is the same as the BCC of the cell

    Hi Jack,
    Bijoy is right,If Backplane is replaced and is OK then further need to check.
    1-TSC & BCC should be same,
    2-check for FRU,FRL valus
    3-Check for MAIO OFF set
    4-Convert TRX Traffic Channel mode to TCHD instead of TCHH or TCHF.

    Hope will be Helpful

    I have Experienced problem and was resolved by checnging TCHF to TCHD.that can be cheked by ZERO Command…

    Thx
