Abstract

The present invention is a switch controller that provides an interface between a public switched telephone network and intelligent services network components. The switch controller controls the operation of one or more programmable switches that accept calls from the public switched telephone network. Intelligent service network components are used for enhanced service processing, interconnection to external networks, and other call functions. The switch controller includes a switch controller application program. Within the switch controller application program are multiple routines that perform call processing. The design of the switch controller application program hides vendor-specific processing and service-specific processing from routines not needing the vendor-specific and service-specific details.
