Abstract: In accordance with an embodiment the method includes temporarily configuring the vector processor with a new set of vectoring coefficients during one or more selected symbol positions; restoring the current set of vectoring coefficients outside the one or more selected symbol positions; obtaining at least one error measure over respectively at least one line of the group of vectored lines during the one or more selected symbol positions; and determining a suitability indication for the new set of vectoring coefficients based on the obtained at least one error measure.

Abstract: The present invention relates to a method for managing transmission resources used for communication over a plurality of mutually-interfering subscriber lines (50).In accordance with an embodiment of the invention, the method comprises assigning a common frequency range (60) over which first sets of carriers are configured for communication over respective ones of the plurality of subscriber lines. The plurality of subscriber lines are dispatched between a plurality of autonomous vectoring processors (21) configured to mitigate crosstalk between subscriber lines coupled thereto, thereby organizing the plurality of subscriber lines into a plurality of distinct vectoring groups (G1, G2). The method further comprises assigning a plurality of additional disjoint frequency ranges (71, 72) to respective ones of the plurality of vectoring groups over which second sets of carriers are configured for enhanced communication over respective ones of the plurality of subscriber lines. The second sets of carriers are configured over the respective disjoint frequency ranges assigned to the respective vectoring groups which the respective subscriber lines belong to.The present invention also relates to a network manager (310) for managing transmission resources used for communication over a plurality of mutually-interfering subscriber lines, and to a transceiver (110, 210) configured to operate a communication channel over a subscriber line.
