Abstract: Aspects of the subject disclosure may include, for example, obtaining a schedule of spectral segments in a communication link of a communication system. Signal interference is identified in a portion of a number of spectral segments according to the schedule of spectral segments and at least one threshold for detecting interference. A determination is made that a number of signal interferers in the portion of the number of spectral segments exceeds a number of filters and, responsive to the number of signal interferers exceeding the number of filters, use of the number of filters is prioritized to filter signal interference in the portion of the number of spectral segments for suppressing at least a portion of the signal interference detected.
