This paper describes the various fault detection, routine exercise, and diagnostic techniques used in the design of a switching complex. Unlike other electronic switching system (ESS) processors, the processor is entirely self-checking.
Fault detection and diagnosis, maintainability and reliability, microprogramming, self-checking processor, switching systems.
