摘要
An Intelligent Signaling Transfer Point (ISTP) of the common channel interoffice signaling (CCIS) network provides high level control of signaling message routing and of processing of calls relating to telephone services, broadcast services, interactive broadband services and packet switched data services. A network in accord with present invention includes central office telephone switching systems and local routers. Each local router also is coupled through a trunk circuit to one of the telephone switching systems. The local router selectively provides switched telephone call communications services to a plurality of telephone stations coupled thereto. The local router also receives broadband digital signals from a broadband trunk circuit and selectively supplies broadband digital signals to a plurality of digital terminals. The ISTP includes a data switch, a database and a program controlled processor. The switch switches signaling messages between signaling links coupled to the switching systems and the local routers. The database stores call processing data for control of at least some call processing through both the telephone central office switching system and the local router. The program controlled processor recognizes a predetermined condition with regard to at least one call related signaling message from any of the switching systems or local routers during processing of any service call. In response, the processor obtains call processing information from the database, and transmits a signaling message containing the call processing information to the central office switching system or the local router to control subsequent processing of the call.
