Abstract:
A method of signaling in a system comprising a broadband network, a narrow band network containing an originating and terminating switching node interconnected through a signaling network for processing call control messages between the originating and terminating switching nodes, an originating and terminating network access point at the boundary of the narrow band and broadband networks, for respectively interfacing the originating and terminating switching nodes to the broadband network, and mapping and translation means connected to the originating switching node, signaling network and originating network access point, the method comprising the steps of:sending a call control message over the narrow band network from an originating switching node to a terminating switching node, the call control message having a narrowband trunk identifier to indicate to the terminating switching node a trunk for receiving corresponding call related data; and in response to the narrowband network call control message, sending the narrowband trunk identifier through the mapping and translating means and over the broadband network, from the originating network access point to the terminating network access point, for use by the terminating network access point in mapping call related data to the trunk corresponding to the trunk identifier.
