Network Level EMP Effects Sensitivity Study on Selected Telecommunications Equipment

摘要

The EMP Mitigation Program uses a network level approach to assess EMP effects on network performance. The approach is twofold. First, the effects of EMP on network equipment are obtained. The OMNCS has made EMP test program results available on the 1ESS and 5ESS switches; the TD-2 microwave, L4 carrier, T1 Carrier, and FT3C fiber optic transmission systems; and the D4 channel bank. Second, the performance of the network exposed to EMP is characterized. This is accomplished by combining the equipment test program results with the network topology. A computer model, predicated on a statistical interpretation of EMP test data, processes this information and calculates a metric to characterize network performance. The model is run multiple times in a Monte Carlo process to calculate probabilistically the point-pair connectivity metric. Point-pair connectivity is a measure of the surviving connections with respect to the original connections. In estimating network performance the model acknowledges fundamental uncertainties in the supporting input data.
