A system and process for customizing the performance of an xDSL communication system in which a transmitting modem and a receiving modem will negotiate a performance parameter for adjustment. The receiving modem measures the signal to noise ratio on the xDSL loop and, based on that measurement, sends a request to the transmitting modem to make a specific adjustment to the selected performance parameter. The transmitting modem will make the adjustment upon receipt of the request from the receiving modem. In a preferred embodiment, the modems will choose either the data rate or the transmission power level as the performance parameter for adjustment. In a multiple xDSL system in which the xDSLs affect each others' performance through crosstalk, the present invention allows a first modem pair to instigate a transmission power reduction, which will in turn allow a second modem pair to either increase its present data rate or decrease its transmission power. Through this combination of transmission power adaptation and data rate adaptation, it is possible to reduce the performance variance between the individual communication sessions or customize the performance profile according to specific customer requirements.
