    Hi,

    1. Kindly check the alarms whether there is alarms on TRX, Combiner, etc
    2. Check Interference, (Co/Adj BCCH or other freq), change the ARFCN to the clean one.
    3. Finally, you can move the SDCCH Channel to the other Trx which is clean

    hi taki
    i suspect transmission link ,and i advice you to ask for investigation A interface with
    protocole analyzer,maybe there is hardware problem in bsc level matrix responsible to make connection through transmission link between bsc and bts devices during immediate assignmente.
