    I am working with a fixed line prepaid system for an operator.
    the design parameters are as follows

    Customers specify as follows:

    Average Call Holding Time = 230 seconds
    Subscriber base = 1,500,000
    Busy Hour Call Attempt =30,000
    therefore erlang/sub = 0.00128 (BCHA x ACHT)/(Subs x 3600)

    Due to above specs, customer anticipate the following:

    call/sec handled by system should be = 8.33 (BHCA/3600)
    Concurrent Call Handling = 1,917 (ACHT x Call per Second)

    Actual system performance are as follows:

    ACHT (actually measured) = 411 second
    Sub (actual readings from system) = 765,663
    BHCA (actual readings at STP) = 20,000

    From BHCA Calls per sec=5.56 (20000/3600)
    Concurent calls = 2283 (5.56 x 411) ie ACHT x call per sec

    To ensure system stability, we interim gapped the calls to 1000
    concurrent calls. So calls per second=2.433 (1000/411) and resulting
    in BHCA = 8759 (2.433 x 3600 or call per sec x 3600)

    From the above, Can I say that the system is performing better then the
    design criteria specified by the customer even when I call gapped
    the system ?

    Appreciate a second opinion from experts out there. Thanks

    Not really. They havent provided you with the volume to show that the system performs better. Have you benchmarked CPU utilization of the peripheral?

    In case of a Softswitch system, is the call setup time considered a part of Call holding time.
