Abstract

A telecommunications network incorporating an Advanced Intelligent Network having a service control point including a centralized database and having a peripheral platform comprising an Intelligent Peripheral providing at least one auxiliary call processing capability. The service control point is in communication with a network switching system via a common channel signaling communication network. The peripheral platform is in communication with the service control point over a second data connection and is in communication with switching systems in the network switching system over F links and voice channels. The individual switching systems are in connection with one another through F links. The peripheral platform is capable of call management which obviates the necessity of using the common channel signaling system to accomplish the same call management. The service control point is arranged to act proactively to issue instructions to the peripheral platform to expedite call management.
