    Hi all,
    I am facing big issue on TBF Congestion.
    BTS3900_GSM is working over IP with Fix Abis as a Flex Abis mode.
    No high DL Throughput on this site.
    Am thinking that it can be parameters configuration issue.
    Someone can help me,Please.

    hi again,

    tbf congestion can be caused by
    – radio congestion (not enough pdch to serve required tbf)
    – abis congestion
    – Gb congestion
    – bsc board congestion

    try to find counters which will provide a more detailed cause of the congestion.Check also the load of all the interfaces/boards described above.
