The survivability of the Public Switched Network PSN during various emergency situations is based, in part, upon a high degree of redundancy of routing in the network. In the PSN the redundancy exists in two forms, the multiple geographical routing of calls and the multiple types of media between the PSN switching offices. A measure of survivability, for the PSN based upon these type of redundancies was determined. This thesis augments the Nationwide Emergency Telecommunications System NETS studies of the National Communication System by developing a model for determining the effects of redundant routing on NETS survivability. The model examines possible geographical and media variables in representative sets of links and nodes for PSN class 3, 4, and 5 offices. This thesis presents a methodology for determining the survivability of NETS. Author
