What is the total offered traffic intensity from a PBX/PABX to PSTN if 10 calls are made, each with a duration of 6 minutes during 1 hour?
Problem 4
Use the Poisson (or “Molina lost calls held”) trunking formula to calculate the blocking probability (GoS) when the total offered traffic is 2 Erl and the number of available transmission channels in the network is 5.
