Abstract
A method and apparatus for transmitting data over a line where the data is received for transmission at a fixed rate. The data is buffered and transmitted over the line at a rate faster than the fixed rate to create 'dead' times used for calibration. Calibration signals are transmitted over the line during the dead time to determine the characteristics of the line.
