    Hi,

    I am planning the traffic for a national, terrestrial voice network. I can calculate the amount of E1 interfaces at the local exchanges from the number of users, but what is the average usage of those E1 lines, looking at the traffic on the national backbone? Are there standard values for that?

    Thanks a lot,
    Guenther

    Hi,

    How do you calculate the amount of E1 interfaces at the local exchanges from the number of users ?

    Hi Guenther,

    What is the offer traffic which you already compute to get the number of E1?… Usually the usage in the erlang unit, which we get from offer traffic.

    Hi Guenther,

    I hope you are very clear of Grade of services( GoS , i.e % blocking )while calculating the number of E1s required, also it depends on number of subscribers and the erl/subscriber considered.

    and for % ultilisation of your calculated trunks(E1s) take busy hour (traffic carried in erlangs / offerred erlang(calculated))*100
