Abstract

An overview is given of the Bellcore system hardware reliability prediction process as applied to commercial telecommunications switching systems, with verification testing, and generation of reliability predictions. The `Reliability performance objectives for LATA (Local Access Transport Area) switching systems´ document specifies several reliability measures to be used in the analysis of commercial telecommunications switching systems. The measures are total system downtimes, total system failure rate, partial system downtime, individual line (or trunk) downtime, cutoff call probability, probability of an ineffective machine attempt, and line (or trunk) failure rate
