Hi everybody

I hope everyone is having a great weekend.

The web-based Erlang B calculator located at

takes our Erlang and GoS values and calculates the required number of trunks to

accommodate the busy hour traffic with a specific GoS.

Let say we calculated number of trunk to be 3 for a given Earlangs and GoS ( grade of service).

What is the bandwidth per trunk?

thanks and have a great weekend
