Common Channel Interoffice Signaling: Peripheral Maintenance and Administration Support System
01 February 1978
Peripheral Maintenance and Administration Support System By R. C. SNARE (Manuscript received May 7, 1977) Common Channel Interoffice Signaling (CCIS) introduces a new network for routing signaling information, new equipment, and new functions for which performance must be monitored. Reliable, timely (within seconds or minutes in many cases), and readily usable performance reports are required by traffic and maintenance personnel to administer and maintain these new capabilities to provide the high quality of service to which customers are accustomed. The Peripheral Bus Computer (PBC) System provides the maintenance and administration support required by the CCIS signaling network, Signal Transfer Point (STP) offices, and toll crossbar switching offices. This article describes the PBC and the support it provides CCIS.
