Abstract:
A system for allocating bandwidth for a call having call signaling and user communications, the system comprising:a virtual path group having a plurality of virtual paths having bandwidth initially under-allocated to each of the virtual paths;a signaling processor adapted to re-allocate the bandwidth available to a particular one of the virtual paths in a particular one of the virtual path groups when the bandwidth initially allocated to the particular virtual path is not sufficient to connect the call so that the particular virtual path uses bandwidth initially allocated for another virtual path in the virtual path group, to process the call signaling to select a connection over the particular virtual path, and to transport a control message that designates the selected connection; andan interworking unit adapted to receive the user communications in a communication format, to receive the control message from the signaling processor, to interwork the user communications between the communication format and asynchronous transfer mode cells that identify the selected connection, and to transport the asynchronous transfer mode cells over the selected connection.
