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.
