Abstract:
A telecommunications system for providing a service for a call, wherein the telecommunications system comprises;a signaling processor that is operational to receive and process a first telecommunications signaling message for the call and to provide a first control message, a second control message, and a second telecommunications signaling message for the call;a first ATM interworking multiplexer that is linked to the signaling processor and that is operational to receive narrowband traffic for the call over a first narrowband connection, to convert the narrowband traffic from the first narrowband connection into ATM cells that identify a first virtual connection based on the first control message, and to transmit the ATM cells over the first virtual connection;an ATM cross-connect system that is connected to the first ATM interworking multiplexer and that is operational to receive the ATM cells from the first ATM interworking multiplexer over the first virtual connection and to route the ATM cells from the first virtual connection based on the first virtual connection identified in the ATM cells;a second ATM interworking multiplexer that is connected to the ATM cross-connect system and linked to the signaling processor, and that is operational to receive the ATM cells from the ATM cross-connect system over the first virtual connection, to convert the ATM cells from the first virtual connection into the narrowband traffic, and to transmit the narrowband traffic over a second narrowband connection based on the second control message; anda narrowband switch that is connected to the second ATM multiplexer and linked to the signaling processor, and that is operational to receive the narrowband traffic from the second ATM multiplexer over the second narrowband connection and to apply a service to the call based on the second telecommunications signaling message.
