Abstract
A two-wire line conditioning apparatus utilizing dial tone for alignment. Variable impedances are iteratively adjusted using a multitone calibration signal. The hybrid device filters out dial tone components in measuring the echo of the multitone signal during the variable impedance adjustment. The level of the dial tone is measured to determine the overall gain that is to be inserted on the line by the line conditioning apparatus.
