The No. 1/1A Electronic Switching System (ess) will play an important role in the evolving Stored Program Controlled (spc) Network because, as a major electronic switching system for local and combined local/toll service, it provides direct interfaces to many of the Bell System's customers. It provides important capabilities required for System 800 Service and for a variety of other new spc network services. This paper describes several of the basic spc network capabilities provided by the No. 1/1A ess. It also describes the architecture and implementation of its common‐channel interoffice signaling (ccis) subsystem, ccis call‐processing software, and System 800 software.

This paper traces the evolution of the AT&T common channel signaling (CCS) network from its initial deployment as the common channel interoffice signaling (CCIS) network in 1976 to its present and future forms. Since the introduction of CCIS, the network has: added datagram direct‐signaling capability, been reconfigured as a result of the AT&T divestiture, and been modernized by new digital and processor technology and by developments in software engineering techniques. In addition, the CCS network has become a key part of the AT&T service architecture, allowing faster nationwide deployment of services. The globalization and further functional enhancements of the network are also discussed.
