    摘要: A crosstalk cancellation device cancels crosstalk noise of at most M disturbing communication lines in a victim communication line forming part of a vectoring group. The crosstalk cancellation device gradually decreases the cancellation depth of a cancelled disturbing communication line in the victim communication line upon a crosstalk noise variation in the vectoring group requiring cancellation of crosstalk noise of a not yet cancelled disturbing communication line in the victim communication line.

    摘要: The present invention relates to a crosstalk estimation device for estimating crosstalk between disturber communication lines and victim communication lines. The crosstalk estimation device is able to change the power spectral density PSD on the victim communication lines and/or the disturber communication lines. The crosstalk estimation device further receives measured changes in operational parameters on the victim communication lines and/or disturber communication lines in order to estimate the crosstalk induced in the victim communication lines and/or disturber communication lines.

    摘要: In a network for digital data packet transmission, reception quality of received data packets is sensed (111) by a remote terminal (101). Thereupon, a bit string indicative for the sensed reception quality is generated (112). This bit string or a compressed version of this bit string is transferred (114) in real-time over a management channel to a first central processing unit (121) in a network node (102) where the bit string is compacted or processed. By processing the bit string, the first central processing unit (121) may determine impulse noise characteristics. Alternatively, the bit string or a compressed or compacted version thereof may be forwarded to a second central processing unit (131) in a network manager (103) that processes the bit string and determines impulse noise characteristics.

    摘要: A method includes maintaining temporally parallel DSL data communication sessions with DSL modems of a group via a set of lines. The method includes, in response to substantially stopping to receive DSL communications from one of the DSL modems via one of the lines, transmitting a substantially reduced average power to the one of the lines and monitoring the one of the lines to determine whether DSL communications have restarted being received from the one of the DSL modems. The method also includes resuming the maintaining of the temporally parallel DSL communication sessions in response to the monitoring determining that DSL communications have restarted being received from the one of the DSL modems.

    摘要: In a network for digital data packet transmission, quality records are stored in a memory. Each of the quality records is indicative for a reception quality being sensed of one or more received data packets. Thereupon, upon overflow of the memory, one or more of the quality records is discarded from the memory. For at least one of the quality records, discarding weights are generated as a function of at least one of the quality records and associated to the quality records. Hereby, upon such overflow, the discarding weights are taken into account in predefined rules and conditions according to which the discarding of the quality records is performed.
