Centralized maintenance and administration of electronic switching systems

Centralization of surveillance, control, and analysis of Electronic Switching Systems is gaining wide acceptance throughout the telephone industry as the appropriate approach to maintaining high standards of reliability in a cost-effective manner. This paper discusses some of the major issues confronting the design of systems that support this centralization. These issues include force management and work control concepts as well as specific design constraints on the systems themselves. The No. 2 Switching Control Center System, which is the principal Bell operations system supporting this centralization, is used as a vehicle to describe specific issues involved.
