Abstract

A system and method for interposing in the feeder system of a switched telecommunications network an adjunct programmable program controlled switching system providing preselection of service providers and the functionalities provided. The adjunct switching system is preferably enclosed in a controlled environment vault existing in the feeder system of the telecommunications network and housing optical to electrical interfaces. The system and method provide for by-passing the end office switches in the telecommunications network to connect subscribers to various services such as competitor local exchange networks, LANs, interexchange carrier points of presence, the Internet, packet data networks, wireless communication systems, traffic operator position stations, video services, and the like. The adjunct switching system provides both wideband and narrowband switching.
