I have two questions. The first one is….Does anyone know what the probabilty of blocking is for the PSTN? I come from a mobile background where the goal is usually 2%.
Second. I have a design problem where I am allocating a fixed number of lines between two sites based on the amount of traffic between them. I need to determine what percentage of traffic is handled by lines 1 and 2 out of 5 total lines if it is assumed that if a call comes into an empty system it’s given to line 1 and if it comes into a non-empty system, it’s given to the lowest numbered link that is not busy. This involves using a Markov chain and the call arrival rate (.2) and call departure rate (n/5).
