Abstract
Abstract The instant communications system and method for controlling both digital voice traffic and digital data traffic includes a communications path, a source station and a destination station. The source and destination stations are respectively adapted to be coupled to a source station home network and to a destination station home network. The source station is further adapted to transmit a signaling packet on a first transmit control channel. The signaling packet is for signaling a destination station that the source station has an information packet intended for the destination station. The destination station is adapted to detect the signaling packet on a second receive control channel. The signaling packet includes a field for identifying the source station which has the information packet intended for the destination station. In response to the signaling packet, the destination station is coupled to the source home network. Thereafter, information packets may be transmitted from the source station on a third control channel and then be translated to a source station home network channel for transmission to the destination station.
