Abstract: One embodiment of the invention includes a master timer controller for a controlling a controller configured to implement a plurality of functions at each of a respective plurality of scheduled times, each of the plurality of scheduled times is converted to a respective plurality of time values associated with a master timing protocol The master timer controller has a plurality of comparators configured to compare the accumulated time value with each of the respective plurality of time values, each of the plurality of comparators being further configured to generate a respective one of the plurality of control signals upon the accumulated value of the master timer being equal to the respective one of the plurality of time values. Another embodiment also includes a method for managing timing functions associating with at least one timing protocol.

Abstract: One embodiment of the present invention includes a system for managing timing functions associating with at least one timing protocol. The system comprises a controller configured to implement a plurality of functions at each of a respective plurality of scheduled times. The system also comprises a time protocol converter configured to convert each of the plurality of scheduled times to a respective plurality of time values associated with a master timing protocol. The system further comprises a master timer controller configured to generate a plurality of control signals associated with the plurality of functions based on an accumulated value of a master timer associated with the master timing protocol relative to the plurality of time values.

Abstract: A method of communicating across a channel includes receiving information having a known bandwidth and a known spectrum. The information is preferably in the form of a multicarrier modulated signal, e.g., a DMT signal. In one aspect, this information is received at a receiver having a reduced channel bandwidth. An aliasing spectrum can be calculated based on the known spectrum and the frequency difference between the known bandwidth and the reduced-channel bandwidth. The received information can then be modified based upon the aliasing function to compensate for alias distortion. For example, the received information can be modified by modifying the noise component or signal-to-noise ratio of the received information.

Abstract: A multi-client ADSL modem network (10) that can be configured for a home or office network when multiple ADSL client modems (18) are installed in different communication terminals (22). One ADSL modem (14) at a central office (12) coordinates the remote multi-client modems (18) for communication over a single twisted pair loop carrier phone line (16), allowing the connected modems (18) to communicate not only with the CO modem (14), but also with each other by sharing frames, tones, or by code division techniques on upstream channels. The CO modem (14) operates as a network hub and/or arbitrator, and facilitates one ADSL modem to become the master modem and maintain a superframe. The present invention provides home network ADSL service without extra wiring or equipment, thus providing a low cost approach for home networking of ADSL service.
