  • System and method for reducing noise induced by digital subscriber line (DSL) systems into services that are concurrently deployed on a communication line
    Publication number: 20030108095
    Abstract: Systems and methods are presented for reducing noise induced by digital subscriber line (DSL) systems into services that are concurrently deployed on a communication line. In the disclosed technique, a power level of a discrete multi-tone (DMT) sub-carrier is adaptively calculated from a signal that is received from a communication line. The signal has information indicative of line conditions, which are further indicative of services deployed on the communication line.
