    Dear all
    how much calls One signaling link can handle…. at 40% loading

    you mean one RSL ?

    One FR call (or 2 HR calls, or 1 SDCCH) generates about 0.4kb/s of signalling (that’s the SACCH net bitrate)

    One RSL is dedicated for 1 TRX (= 8 timeslots)

    8 FR calls, or 16 HR calls, or 8 SDCCH timeslots generate a minimum throughput of:
    8 * 0.4 kb/s = 3.2kb/s

    1 RSL is usually located on a quarter of an ABIS timeslot, i.e. 16kb/s. Even at 40% loading, that’s more than enough to carry all the signalling for all the possible traffic.

    it seems like he said about ccs7 link. I think that answer is 1024 calls.

    ol,

    yes, that makes more sense 🙂

    IT IS NOT POSSIBLE TO SAY EXACTLY THE FIG OF CALLS BECAUSE ISUP MESSAGES GENERATED BY LANDLINE TO LANDLINE, LANDLINE TO BOBILE, IN CALLS , HOLDING TIME OF EACH CALL IS DIFFERENT. IF IT IS 0.4 ERL
    ERL TRAF=CT/60 T=AVG HOLDING TIME AND C =NO OF CALLS. IF U HAVE AVG HOLDING TIME THEN U WILL GET THE CALLS.

    such formula gives us not ccs7 link’ call amount, but one TCH TSL call amount per hour.

    signalling capacity, if ss7 and if a 12 bits type for instance, then, 1 link can handles (2 to power 12) that is 4096 traffic circuits.

    Generally, a ss7 / C7 link is dimensioned to handle 40% load. Once exceeded another link will be selected by using the SLS load balancing algorithm. The link set will have upto a maximum of sixteen links.
