A multi-services access system (205), such as a multi-services digital loop carrier (DLC) system for a telecommunications network, has a packet-mode card, such as a digital subscriber line (DSL) card (209), configured to receive data packets corresponding to one or more data signals and derived-voice packets from a single packet-mode customer premises equipment (CPE) unit (131), wherein the packet-mode card determines whether each received packet is a data packet or a derived-voice packet. The access system also has a packet interface (211) configured to receive the data packets from the packet-mode card and to transmit the data packets to a packet-switched network (119) for packet-based switching. In addition, the access system has a derived-signal server (219) configured to receive the derived-voice packets from the packet-mode card and to convert the derived-voice packets into a digital voice stream, as well as a controller (215) and a circuit interface (217) configured to receive the digital voice stream from the derived-signal server and to transmit the digital voice stream to a circuit-switched network (125) for circuit-based switching. Since the access system is able to assign resources dynamically to packet-mode CPE units (as opposed to prior-art DLC systems, which have resources pre-assigned), the system of the present invention is able to utilize system resources more efficiently. Moreover, since the system has an internal derived-signal server, there is no need to transmit derived voice signals outside of the system for conversion.
