    Hi,
    I am not sure how to
    a) calculate the carry traffic and
    b) calculate the traffic blocked

    for an E1 circuit installed between a PBX in a Call Center & a local exchange, if the GoS is 1%.

    Does E1 play any role in that question to solve a) & b)?

    MANY THANKS!

    An E1 consists of 24 channels. You may easily look up from an Erlang-B table for the traffic corresponding to a 24 channels with 1% blocking. The figure is 15.3 Erl. It means that an E1 can support a traffic of 15.3 Erl with a tolerance of 1% being blocked.

    It appears (I’m not quite certain) that 0.153 Erl traffic would be blocked. The “carry traffic” should then be 15.147 erl [15.3 less 0.153].

    In your case, the capacity of the bottleneck should be of concern. And the bottleneck may not (actually, not likely to be) the E1.

    Please correct me if I am not right.

    No, an E1 is 30 channels; sometimes 31. A T1 is 24 channels.
