Common channel signaling: the nexus of an advanced communications network
S.M. Boyles, R.L. Corn, L.R. Moseley · IEEE Communications Magazine · 1990
An overview of BellSouth's current and future common channel signaling (CCS) network is presented. The current network and its architecture are described. Network element testing and network interconnection in a multivendor, multinetwork environment are discussed. Services offered by BellSouth via the existing network are summarized. Future plans for the CSS network are outlined. These include the establishment of a target architecture that will permit the rapid introduction of a wide range of communications services in a manner consistent with the probable evolution of the market and the regulatory environment. The introduction of two BellSouth programmable nodes-the local service control point (SCP) and the ISDN service node-is described. Advanced services are highlighted.>
