Abstract: A vectoring controller for configuring a vectoring processor that jointly processes DMT communication signals to be transmitted over, or received from, a plurality of N subscriber lines according to a vectoring matrix. In accordance with an embodiment, the vectoring controller is configured, for given ones of a plurality of tones, to enable the given tone for direct data communication over a first set of N−Mk targeted lines out of the plurality of N subscriber lines, and to disable the given tone for direct data communication over a second disjoint set of Mk supporting lines out of the plurality of N subscriber lines, Mk denoting a non-null positive integer. The vectoring controller is further configured to configure the vectoring matrix to use an available transmit or receive power at the given tone over the second set of Mk supporting lines for further enhancement of data signal gains at the given tone over the first set of N−Mk targeted lines.

Abstract: The present invention relates to a method for assigning transmission resources (101) to communications between an access node (11) and a plurality of subscriber devices (41 to 46) coupled to a shared transmission medium.In accordance with an embodiment of the invention, the method comprises characterizing interference between respective ones of the plurality of subscriber devices over the shared transmission medium, grouping highly-interfering subscriber devices into respective interfering groups (G1, G2, G3, G4) based on the so-characterized interference, and assigning disjoint transmission time intervals to upstream communication from any one subscriber device of any one interfering group and to downstream communication towards any other subscriber device of the same interfering group.The present invention also relates to a resource controller.

Abstract: A distribution point unit using discrete multi-tone technology, the distribution point unit being configured for connection to a wired shared medium associated with an available spectrum, the wired shared medium connecting the distribution point unit with a plurality of users, the distribution point unit including an assigning unit configured for assigning a first portion of the available spectrum to a first user of the plurality of users and a second portion of the available spectrum to a second user of the plurality of users; a sending and receiving unit configured for encoding and decoding digital data, using discrete multi-tone technology, and configured for sending and receiving encoded digital data over the assigned first portion to/from the first user and over the assigned second portion to/from the second user.
