    摘要： A method and apparatus for graceful preemption on a digital communications link used for selective communication from a plurality of user devices. Link controllers are used to implement the enforcement of a protocol on the link. When a first user device is actively communicating over the link, a second user device can gracefully preempt the first user device by having a link controller transmit a preempt character. The link controllers at either end of the link each save values of a set of status variables collectively defining the status of the link controller. When the second user device relinquishes link access, the saved values are used to return the link controllers to their status at the time of preemption such that the first user device can resume communication from the point of interruption without requiring data retransmission.

    摘要： A method a system for automatically controlling an adaptive interleaver involves monitoring performance parameters of a transmission system and controlling the adaptive interleaver in response to the performance parameters. The SNR and the data rate of the transmission system are preferably determined. The data rate is analyzed and the adaptive interleaver is adjusted in response to the data rate and the SNR. Alternatively, the BER and the data rate of the transmission system are determined. The data rate is analyzed and the adaptive interleaver is adjusted in response to the data rate and the BER. Alternatively, any one of the SNR, BER or data rate can alone be monitored and used to the adaptive interleaver. The system provides a effective system for adjusting an adaptive interleaver in response to performance parameters of a transmission system.

    摘要： A method and system for optimizing coding gain that alters the backsearch buffer length and/or the input buffer length of a decoder in response to one or more transmission performance characteristics of the system. The performance characteristics are monitored to determine the performance of the system. The measured transmission performance characteristics are used to control the lengths of the backsearch buffer and the input buffer. The measured transmission performance characteristics along with the backsearch length and/or the input buffer length are analyzed and compared with simulated decoding results. In accordance with the simulated results, the system determines the optimal size of the backsearch buffer and the input buffer needed to achieve a desired performance target. The system adjusts the size of the backsearch buffer length and/or the input buffer length to equal the determined optimal lengths.

    摘要： An apparatus for filtering radio frequency interference in a signal transmitted on a twisted-pair communication channel such as an ADSL transmission line. The apparatus includes a filter adapted to be selectively engaged in-line with the communication channel by a switch or switches when the differential mode noise in any predetermined frequency sub-band exceeds a threshold noise level, or the sum of the sub-band noise signals exceeds a wideband threshold noise value. When the filter is not engaged, it is isolated from the communication channel by a bypass switch or pair of bypass switches.
