    Hi,

    the Abis does not need any idle timselot. So the answer is “zero”.

    I assume you want to compute how many Abis TS are used by the BTS, and how many are left ? Am I right ?

    Regards

    OML needs 1 timeslot (64kbps) = 4 sub timeslots (16kbps)
    RSL for S4/4/4 = 6 timeslots (64kbps) = 24 sub timeslots (16kbps)
    TCH for S4/4/4 = (12 TRXs x 8 TCHs) – (3 BCCHs) – (6 SDCCHs) = 87 sub

    So you have 128-4-24-87=13 16k(4, 64k) ts for abis ts

    4 for Synchronization
    4 for OML
    8 for TRx(2 for Rsl)
    IF config is 2,2,2
    4+4+(10*6)=68 are used
    128-68=60 Idle Time slots
