Abstract
The invention is a tandem system for providing a tandem connection for circuit-based traffic. This tandem system comprises an ATM cross-connect, ATM interworking multiplexers, and a signaling processor. The multiplexer converts the traffic received by the tandem system into ATM where it is routed through the cross-connect and re-converted back into the circuit-based format at an ATM interworking multiplexer. The signaling processor controls the virtual connections and out going circuit-based connections used by the multiplexers.
Claims54
A software product for controlling a tandem communications system, the software product comprising:
- call processing software operational when executed by a processor to direct the processor to receive signaling information associated with an incoming DS0, process the signaling information to select an identifier and a connection for an outgoing DS0, wherein the identifier is for asynchronous communication within the tandem communications system between the incoming DS0 and the outgoing DS0, and transfer control information identifying the incoming DS0, the selected identifier, and the selected connection;
- a control interface operational when executed by an asynchronous interworking system to direct the asynchronous interworking system to receive the control information and identify the incoming DS0, the selected identifier, and the selected connection to asynchronous adaption layer logic in the asynchronous interworking system;
- and
- a software storage system storing the call processing software and the control interface.
