The physical layer session resource broker (PHY SRB) according to the invention receives request from application servers (VOD SERVER, TV BRDCST SERVER, GAME SERVER, WEB SERVER) which are translated into physical layer parameter values. The physical layer parameter values are imposed on the access nodes (DSLAM) by the physical layer session resource broker (PHY SRB).

Physical layer session resource broker

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.

Method for data-signal quality control, a related receiver and a related transmitter

A power control method for transceiver units conveying data over discrete tones. The method includes the steps of: determining a transmit power over a physical channel for each individual tone, such that this transmit power maximizes a weighted function of data rates achievable with this tone over the physical channel and over modeled neighboring channels, with the constraint that this transmit power conforms to a transmit power mask, summing up the data rates over the whole set of tones, adjusting the weights such that the total data rates over the modeled neighboring channels reach some target data rates, and such that the total data rate over the physical channel is maximized, with the constraint that each weight is identical over the whole set of tones.
