Trunking efficiency formula
WebWith these assumptions, we can derive the Erlang C formula, for the probability that a call will be delayed: P [delay > 0] = TNC tr TNC tr +N C!(1 −T tr/N C) P N C−1 k=0 T k tr/k! (2) It is typically easiest to find a result from a figure. I am providing Figure 3.7 from [1].

WebC), and thus the trunking efficiency will be lower. Example: Decrease in trunking efficiency for constant N Let N = 7, each cell has N C = 100 channels, and users who make calls with λ = 0.01 per minute with average holding time 3 minutes. For blocked-calls-cleared and a GOS (i.e., Pr block) of 2%, what is the WebFor example, if you are developing a telephone switching system, resources would be things like outgoing digital trunks, timeslots, tone detectors etc. In this article we will focus on resource dimensioning using Erlang-B and Erlang-C formulas. Many times resource dimensioning is determined by simulating the system being developed.
