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.
