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： A crosstalk emulator for a cable, preferably a xDSL telecommunication cable, represented by several emulation paths each comprising a first segment (L1a/L4a) serially connected to a second segment (L1b/L4b) on a printed circuit board PCB. The first and second segments of a same emulation path form an angle, e.g. of about 90 degrees, at their junction point. All the emulation paths have a same length and preferably run in parallel over the PCB. As a result, each emulation path crosses only once (X21) any other emulation path at a cross-point. Furthermore, the area occupied by the crosstalk emulator on the PCB is reduced with respect to a matrix topology, whereby the present topology can easily be extended to large numbers of couplings, allowing design guidance for a passive coupling emulator with a large amount of coupling elements (CP) at the cross-points.

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： 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.
