Abstract
The use of multiple AAL2 virtual circuits to support narrow band calls with multiple types of narrow band signalling systems leads to inefficient use of bandwidths over an ATM network. The present invention provides a method of transporting narrow band calls of multiple narrow band signalling type between narrow band networks across a single virtual circuit in an ATM network, where for each call connection within a circuit the call connection signalling information includes the narrow band signalling type.
