Abstract
The present invention relates to a method for data-signal quality control, a related receiver and a related transmitter in an XDSL communications system, where this XDSL communications system comprises a transmitter and a receiver. The transmitter is coupled to the receiver over an XDSL line, over which the transmitter sends a data-signal on a plurality of data carriers for carrying this data-signal from the transmitter to the receiver. This receiver analyses a quality of the data-signal received by the receiver and subsequently requests the transmitter, in case this quality of the data-signal is beneath a predefined level to improve the quality of the data-signal, by performing an equal transmit power increase over a plurality of the data-carriers. The transmitter in response to the requesting improves the data-signal by performing an equal transmit power increase over at this plurality of data-carriers.
