Looking on the Offered Traffic function stated by the traffic report generation which is Offered Traffic=function of (No. of Available Cct, Carried Traffic) I guess this should refer to the Erlang’s lost-call formula which refers to the call congestion. B, prob. of congestion=(A^N/N!)/(1+(A^1/1!)+(A^2/2!)+…….+(A^N/N!)) where A=Carried Traffc N=Number of circuit Therefore Off. Traff=Carr. Traff/(1-B)
The different outcome, I guess would be due to the pactorial function in the formula.
