Abstract:
A method of operating a telecommunications system to provide a call with a virtual connection wherein a user places the call by transmitting user information to the telecommunications system over a particular connection for the call and by sending signaling for the call to the telecommunications system, wherein the system comprises an ATM interworking multiplexer and a signaling processor coupled to the ATM interworking multiplexer, the method comprising:receiving the signaling for the call into the signaling processor;processing the signaling for the call in the signaling processor to select the virtual connection;generating a control message in the signaling processor to identify the particular connection and the selected virtual connection;transmitting the control message to the ATM interworking multiplexer;receiving the user information for the call from the particular connection into the ATM interworking multiplexer;converting the user information from the particular connection into ATM cells that identify the selected virtual connection in the ATM interworking multiplexer in response to the control message; andtransmitting the ATM cells from the ATM interworking multiplexer over the selected virtual connection.
