Abstract
A system to analyze and compensate for noise on a transmission line (35) is provided. The system comprises a transmission card which includes a transceiver (32), and a microprocessor (34) attached to the transceiver (32). The system also comprises a transmission line (35) coupled to the transceiver (32) and at least one customer premise equipment (38) coupled to the transceiver (32) by the transmission line (35). The microprocessor (34) is operable to monitor the transmission line (32) and determine the signal-to-noise ratio on the line as a function of frequency, and adjust the rate of transmission in terms of bandwidth in terms of bits as a function of frequency.
