Method and apparatus for providing ringing timeout disconnect supervision in remote telephone extensions using voice over packet-data-network systems (vops)

Abstract

A Multiservice Access Concentrator (MAC) provides a time limit for a first ringing voltage signal in response to an attempted call. The call is attempted via a voice over packet-data-network system (VOPS), wherein the VOPS comprises voice over Internet Protocol (IP), voice over Frame Relay, voice over Asynchronous Transfer Mode (ATM), and voice over High-level Data Link Control (HDLC) network systems. Generation of the first ringing voltage signal is terminated upon expiration of the time limit. A control message is transmitted to terminate the attempted call, wherein the control message is transmitted via the VOPS.

What is claimed: 
     
         1 . A method for providing ringed timeout supervision in remote telephone extensions, the method comprising the steps of:
 providing a time limit for a first ringing voltage signal in response to an attempted call, wherein the call is attempted via a voice over packet-data-data network system (VOPS);   ceasing generation of the first ringing voltage signal upon expiration of the time limit; and   transmitting a control message to terminate the attempted call, wherein the control message is transmitted via the VOPS.
