Abstract

Disclosed is a method and apparatus for effecting remote access to special services in telephone networks described particularly with respect to call forwarding. An adjunct computer is associated with a Remote Memory Administration System (RMAS) for switches which include a facility for providing special services such as call forwarding. The adjunct computer is inserted between the RMAS and the switches which it controls. The adjunct includes a processor responsive to subscriber identification and stored class of service information to recognize that call forwarding service is to be provided to an identified subscriber station. The processor receives requests for special service via a multiline hunt group associated with a Remote Access Directory Number (RADN) conneted to a voice response unit which feeds request signals to the processor and voice prompt to the caller. The processor determines the identity of the subscriber station which is to receive the requested service and the nature of the service and generates a programming signal and formats the signal for compatibility with the switch to which the station is connected. The processor also transmits to the switch recent change programming signals originating in the RAMS as well as the programming signals to effectuate call forwarding. Buffer memory and multiplexing capability is provided.
