Abstract:
1. A multi-services access system for a telecommunication network, comprising: (a) a packet-mode card capable of being coupled to one or more local derived-signal customer premises equipment (CPE) units to (1) receive upstream packetized data signals and upstream packetized derived voice signals from the one or more local packet-mode CPE units and (2) transmit downstream packetized data signals and downstream packetized derived voice signals to the one or more local packet-mode CPE units; (b) a packet interface capable of being coupled to a packet-switched network to (1) transmit upstream packetized data signals and downstream packetized derived voice signals to the packet-switched network and (2) receive downstream packetized data signals and upstream packetized derived voice signals from the packet-switched network; (c) a circuit interface capable of being coupled to a circuit-switched network to (1) transmit upstream digital streams to the circuit-switched network and (2) receive downstream digital streams from the circuit-switched network; (d) a controller coupled to the circuit interface; and (e) a derived-signal server coupled to the packet-mode card, the packet interface, and the controller, wherein: at least one of the packet-mode card and the packet interface is capable of distinguishing packetized data signals from packetized derived voice signals; the packet-mode card forwards each received upstream packetized data signal to the packet interface for transmission to the packet-switched network; the packet interface forwards each received downstream packetized data signal destined for a local packet-mode CPE unit to the packet-mode card for transmission to the local packet-mode CPE unit; the packet-mode card and the packet interface both forward each corresponding received upstream packetized derived voice signal to the derived-signal server, which converts the upstream packetized derived voice signal into an upstream digital stream and forwards the upstream digital stream to the controller, which forwards the upstream digital stream to the circuit interface, which transmits the upstream digital stream to the circuit-switched network; and the circuit interface forwards each received downstream digital stream to the controller, wherein:
