Abstract
A method of and a system for performing computer simulations to determine a number of blocked calls resulting from cutting selected spans in a telecommunications network with selected levels of overtrunking to determine a level of overtrunking necessary to make the number of block calls resulting from a cut span less than a blocked call threshold. The method forms a capacity demand matrix based on a selected level of overtrunking. The capacity demand matrix reflects a circuit capacity between each pair of origination nodes and destination nodes of the network prior to a cut span. The method forms updated capacity demand matrices that reflect the circuit capacity between each pair of origination nodes and destination nodes of the network after a cut span with various levels restoration. The method runs a call simulation program with data from the updated capacity demand matrices to determine the number of blocked calls resulting from said cut span. The method compares the number of blocked calls for various levels of overtrunking to a blocked call threshold to determine an optimal level overtrunking for the network.
