Abstract: At least one implementation generates at least one time-domain sample in a multicarrier apparatus, and links a first timestamp to the at least one time-domain sample. The at least one time-domain sample may be associated with a Discrete Multi-Tone (DMT) symbol and transmitted to a receiving multicarrier apparatus. The receiving multicarrier apparatus may generate a second timestamp upon receiving the at least one time-domain sample.

Abstract: Allocation of different signal-to-noise margins to different carriers in a multi-carrier system is described. A preferred embodiment comprises assigning signal-to-noise ratio (SNR) margins to carriers in a multi-carrier system, comprises assigning a first SNR margin to a first data service based upon a first service characteristic, assigning a second SNR margin to a second data service based upon a second service characteristic, transmitting data associated with the first data service using the first signal-to-noise margin, and transmitting data associated with the second data service using the second signal-to-noise margin.

Abstract: The invention relates to a line terminating device for a subscriber line which transmits and receives broadband signals via a single subscriber line, a broadband signal being composed of a broadband or narrowband audio-frequency data signal and a broadband higher-frequency data signal and the frequency bands of the voice signal and of the data signal essentially not overlapping. The line terminating device according to the invention has a digital frequency separating filter in the digital section of the line terminating device, which is arranged in the digital section of the line terminating device so that the audio-frequency voice signal is separated from the higher-frequency data signal. In particular, the line terminating device is suitable for separating an ISDN or POTS voice signal from an ADSL data signal.

Abstract: A system with multiple processors sharing a single memory module without noticeable performance degradation is described. The memory module is divided into n independently addressable banks, where n is at least 2 and mapped such that sequential addresses are rotated between the banks. A bank may be further divided into a plurality of blocks. A cache is provided to enable a processor to fetch from memory a plurality of data words from different memory banks to reduce memory latency caused by memory contention.

Abstract: A system with multiple processors sharing a single memory module without noticeable performance degradation is described. The memory module is divided into n independently addressable banks, where n is at least 2 and mapped such that sequential addresses are rotated between the banks. Such a mapping causes sequential data bytes to be stored in alternate banks. Each bank may be further divided into a plurality of blocks. By staggering or synchronizing the processors to execute the computer program such that each processor access a different block during the same cycle, the processors can access the memory simultaneously. Additionally, a cache is provided to enable a processor to fetch from memory a plurality of data words from different memory banks to reduce memory latency caused by memory contention.

Abstract: In an adaptive filter a frequency domain filter is used to enhance the convergence properties of the filter for strongly correlated signals.To reduce the amount of delay in the filter the impulse response of said filter for small values of time is generated by a time domain filter, and said impulse response for larger values of time is generated by a frequency domain filter.
