Title: Method and apparatus for routing calls with a digital cross-connect system

Abstract: A method and apparatus for routing calls that receives a call, identifies the subscriber, determines the preferred call carrier, and routes the call to a line connected to the preferred call carrier, all before the call enters the region between local access transport areas. The invention comprises a digital cross-connect system, a computer with a database connected to the digital cross-connect system, and a service management system connected to the computer. The service management system programs the computer with routing information that corresponds to the subscriber's calling plan. The digital cross-connect system receives calls and sends them to the computer. The computer identifies the call information and uses a routing table to determine the correct call carrier for the call. The computer sends the call with routing information back to the digital cross-connect system where the call is routed to the appropriate local or interexchange carrier, e.g., a local network or long distance carrier.
