A method and apparatus for spectrum management in an xDSL system are disclosed. The method mainly include: determining a transmit PSD mask according to a crosstalk status of a line; performing IWF operation using the transmit PSD mask; and dynamically managing line spectrum according to the result of the IWF operation. Therefore, various embodiments of the present invention allow the DSLAM performance to approximate the OSM performance without the need for a center controller and with a rather simple algorithm in a severe crosstalk scenario. Moreover, the embodiments of the present invention may help to simply the design of DSLAM optimization system and achieve a proper balance between the DSLAM performance and the complexity.
