    Hi Pix,
    Pls guide the following.
    What is TBF?
    Are you aware abut nokia topology in edge/GPRS defination.
    What is default and dedicated TS for data?
    If i have defined a FPDCH in one TRX then, this channel will be used for both the service (ie.GPRS/Edge)?
    And how the 2PDCH can achieve the max. speed by using 8PSK modulation?

    DK, sorry, i am not familiar with Nokia terms.

    a TBF is a connection allocated for one user, during its transfer. It is either UL or DL, so if a user has 2 transfers going on (1 DL and one UL), then it gets 2 TBF.

    KB,

    I’m sure you will find a solution. But first of all, you must find where is the bottleneck 🙂
    Sorry I forgot about previous analysis, but what is your conclusion ?
    Do you think there is PS-congestion on Air, Abis, Ater PS, Gb interfaces ? (Which one? )

    Or do you think the radio quality is poor ? (lot of RLC blocks retransmitted)

    Please investigate your QoS stats…

    Cheers,
    Pix
