    Help,

    Is the formula to convert traffic to erlangs for ss7linkset?

    (say for the entire day)

    (8 * (sifsio + (6 * MSU))
    ————————-
    (duration) * data_rate

    duration = endt – strt in seconds
    data rate = ss7 link data rate????

    Can anyone comment on this?

    This formula is valid for 64K Signalling Links and not valid for High Speed Signalling Links

    data rate in this case 64000

    Hi Scot;

    Load is calculated based on:
    1) One Tome Slot can Carry maximum of 1 Erlang @ one Hour.
    2) Traffic on C7 Signaling Link should be keept bellow 0.3 Erlang per Time Slot.

    so the formula is:

    100*8*(SIFSIO+(6*MSU)
    ———————————–
    (0.3*64000*Number of SL in LS*3600)

    Dear All

    I am working in IN deptt and I have been given a task to calculate the SS7 link load

    The formula that i used is

    Total subscribers * (Avg BHCA/sub * AHT) / 3600 = IN load in Erlangs

    Another one is

    100*8*(SIFSIO+(6*MSU)
    ———————————-
    (0.3*64000*Number of SL in LS*3600)

    which i couldnt get

    which is this the right formula?i will appreciate any suggestions or corrections

    Regards

    Deepak,

    The link between BTS and BSC is the Abis interface. It is a 2MBPS link with 32 timeslots. Every timeslot is for 64 KBPS. Timeslot zero is reserved for signalling and the rest are available for voice and data traffic.

    Regards,
    Sachin

    hai deepak
    the signalling between bts & bsc is on LAPD. I would say that for every TRX(voice channels) u also need to reserve a channel for signalling.
    type of lapd – concentration, multiplexing.

    e.g of lapd concentration on a PCM ts0 – sync, ts-1 will e for trxc signalling and subsequent 2 ts for traffic channels 1-8
