ABSTRACT:
A system which allows modular expansion to provide additional services to high speed data. A high speed data line such as DSL or cable is input to a broadband expandable modem device. The modem device produces an output indicative of the data within the data stream. An expansion output is indicative of voice within the data stream which is separated from the data. The expansion output is coupled to one of a plurality of voice adapters. Each of the voice adapters is expandable so daisy chain communication is possible to add additional layers of voice by simply acquiring additional voice adapters. The system preferably uses USB for the expansion capability.
