Abstract :
Preliminary switching system reliability objectives for integrated services digital network (ISDN) basic rate access (BRA) which include downtime, cutoff call probability, ineffective machine attempt probability, and failure intensity are discussed. The reliability objectives are based on current switching technologies, existing reliability requirements and objectives, past operational experiences, and projected user expectations. Outage definitions, reliability parameters, and downtime parameters are presented
