Abstract
A system and method for connecting a call in an asynchronous transfer mode system remotely controls an interworking unit. A communication device transports user communications and call signaling for a call. A signaling processor processes the call signaling to determine a connection for the call. An interworking unit interworks the user communications from the format in which the user communications are received from the communication device to asynchronous transfer mode cells that identify the selected connection. A cross connect provisions a virtual path between the signaling processor and the interworking unit. The virtual path has signaling virtual path identifier/virtual channel identifier links. The signaling processor transports over the virtual path a control message that designates the selected connection. The interworking unit receives the control message and interworks the user communications to the asynchronous transfer mode cells that identify the selected connection.
