  • xDSL modem with asynchronous transfer mode (ATM) layer & latency reduction implemented in software
    Publication number: 20010005367
    Abstract: An ADSL physical transmission layer retrieves data to be transmitted from either a transmit data buffer, or a dummy cell buffer in the case when no actual data is being transmitted to maintain a continuous data stream in an ADSL data link. The ADSL physical transmission layer and an associated ATM protocol layer are implemented as an interrupt service routine and delayed procedure call respectively in an ADSL software modem application. Because the ATM protocol layer does not fill the transmit data buffer with dummy cell data, it is simpler and faster. Moreover, latency is minimized, and overall system throughput enhanced since the maximum latency is independent of any operating system latency, and is no greater than the size of the cell stored in the dummy cell buffer.
