Abstract: The present invention provides a method, an apparatus, and a system for reducing digital subscriber line interference. The method includes identifying at least one legacy digital subscriber line in a digital subscriber line DSL legacy line set, obtaining a target power spectral density mask value of the legacy digital subscriber line, and reducing power spectral density of a transmit signal on the legacy digital subscriber line according to the target power spectral density mask value.
