Patent ID: 7702007

Claim:
A device for adjusting a transmit power spectrum of a VDSL transmitter/receiver of a communication network, comprising: a means for receiving, from a VDSL subscriber device, an attenuation measure for an attenuation experienced by a signal on a line from the VDSL transmitter/receiver to the VDSL subscriber device; and a means for determining the transmit power spectrum of the VDSL transmitter/receiver for a communication of the VDSL transmitter/receiver with the VDSL, subscriber device based on the received attenuation measure, wherein the means for determining is further operable to determine the transmit power spectrum of the VDSL transmitter/receiver based on a transmit power spectrum of an ADSL, transmitter/receiver and a reference attenuation, the reference attenuation corresponding to an attenuation experienced by a signal on a portion of a line between the ADSL, transmitter/receiver and an ADSL subscriber device, the portion corresponding to a distance between the VDSL transmitter/receiver and the ADSL transmitter/receiver.
