    Well, I have some question from a text book, that I don’t know how to answer it.
    1)What capacity does it have a Frame E1, with 30 voice channels (each channel is equal to a troncal line), with a 70% level of ocupation?
    I’m waiting for the answer…


    Check erlang B law. Find the capacity for 30 channels, with blocking rate of … 0.1% ? (what is your default value usually ?)
    Then take 70% of this capacity.

    Easy 🙂
