Broadband telecommunications system interface
First Claim
Patent Images
1. A signaling processing system for telecommunications calls, the signaling processing system comprising:
- a signaling processor configured to process Signaling System #7 (SS7) signaling, select a connection for a call, and provide a control message to an asynchronous multiplexer wherein the control message identifies the selected connection and causes the asynchronous multiplexer to interwork ISDN bearer communications into broadband bearer communications using the selected connection; and
a signaling converter configured to receive Integrated Service Digital Network (ISDN) signaling from the asynchronous multiplexer, convert the ISDN signaling to the SS7 signaling, and provide the SS7 signaling to the signaling processor.

Abstract
The invention is a system for interfacing an ISDN or non-ISDN system with a broadband system. The broadband system can be an ATM system. The invention can process the ISDN signaling to select ATM connections and then interwork the ISDN connections with the selected ATM connections. The invention can interwork ISDN signaling and SS7 signaling. The invention can also process SS7 signaling to select ISDN connections and then interwork ATM connections with the selected ISDN connections. The invention can also interwork ISDN systems with non-ISDN systems.
