How do you calculate the % of usage for each trunk group in the switch? Can someone send me step by step instructions??

It's really tricky. to engineer your traaffic loads. You can use Erlang b charts, requiring the number of ccs (hundred calling seconds) in a busy hour. The Engset Calculator might be helpful. It can be used to work out how many lines you need for a trunk group if you know the Busy Hour Traffic which the trunk group is offered. It should be used instead of the Erlang B Calculator when the number of traffic sources is finite (less than ten times the number of lines).

might have other helps as well.
Good luck.

If you're using ASA it has a built-in traffic calculator (Trunk Anaylzer). It does not take into account overflow or alternate routing. It treats each trunk group as a stand-alone.

4meravaya- thanks for the advice but I still do not know how to use the trunk analyzer..it's like I can not manipulate the date to show two weeks, it is stuck on 1 date and every ASA terminal we have has a diffrent date in the trunk analyzer, any suggestions??
