Assume 0.05 Erlang per PSTN subscriber.
3000 Subscribers generate 150 Erlang requiring at least 6 E1 Trunks(180 channels of 64 kbps)required for non-blocking on circuit-switching
If the traffic is transported over IP, what shall be the bandwith required in KBPS ??
Is there any formula please?? Thanks.
