Abstract: A device or interface driver is provided for permitting an operating system to utilize, configure and control a software modem having forward compatible and expandable functionality. In a preferred embodiment, the operating system is a Windows based system running on a host processing system such as a personal computer, and the modem is compatible with standards promulgated for ADSL. Conventional voice band modem control commands are also supported, so that the present invention for ADSL based modems is nevertheless compatible with existing modem applications programs. The new driver manages control information for configuring the bandwidth to be used in a data link established through a channel with an upstream transciever during an initialization process, and serves as a data pump for the software modem. The control information may be self-determined by a user of the host processing system 398, or alternatively, automatically sensed, configured and monitored by such processing system.

Abstract: A high speed communications system is provided which uses a selectable, desirable portion of the total available bandwidth of a transmission channel. In a preferred embodiment, the invention is an ADSL compatible modem which selects a sub-set of the available downstream DMT sub-channels based on an evaluation of such sub-channels by appropriate signal processing circuitry. An analog front end (AFE) contains sub-band filtering causes an upstream transceiver to use only this selected number of available sub-channels for downstream data transmission. This reduces hardware costs and complexity while still preserving compatibility with applicable ADSL standards and providing a high speed data link. The target data rate of the modem can be further enhanced to the point of achieving fill protocol capability by increasing or upgrading the AFEs, and/or the signal processing circuitry in order to increase the number of processable transmitted downstream sub-channels.

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.
