A Multiservice Access Concentrator (MAC) receives information comprising at least one data stream, at least one voice channel, at least one video stream, Local Area Network (LAN)-based traffic, and facsimile traffic. The received data stream is packetized, and the packetized data stream is multiplexed with the voice channel and the video stream to form an integrated transport stream. The voice channel comprises compressed and uncompressed voice information. The integrated transport stream is provided to at least one multi-service network using a software-configurable trunk. The multi-service network includes cell-based and packet-based networks comprising Asynchronous Transfer Mode (ATM), Frame Relay, High-level Data Link Control (HDLC), Internet Protocol (IP), and Time Division Multiplex (TDM) networks, as well as leased-line carrier services. The trunk is configured at a physical level and a protocol level using at least one trunk option.
