Call duration takes 4 minutes long. Can you tell me the BHCA? And if i have unlimited lines, the traffic is…? Blocking provability?
RajGuestIs it possible to get Utilised erlangs value more than the trunks available???
I mean i got 100 circuits in a route. With a blocking factor of 0.01, designed erlangs would be 84.064 (Courtesy: Erlang calculator)
But practically i have observed the Utilised erlangs value: 107.38
Whether the above figure is correct? Did it mean that there are more rejections in that route??
As per my understanding, the utilised erlang figure cannot go beyond the Circuits…Am i right???
