Abstract

Methods and apparatus to detect wideband interference in digital subscriber line (DSL) systems are disclosed. An example method comprises retrieving a first plurality of performance parameters for a first time interval for respective ones of a plurality of DSL modems, wherein each of the plurality of DSL modems are associated with respective ones of a plurality of subscriber loops, and comparing each of the performance parameters to a threshold to determine whether two or more of the respective ones of the plurality of subscriber loops experienced respective performance degradations during the first time interval. The example method further comprises determining whether the two or more subscriber loops that experienced the respective performance degradations during the first time interval are communicatively coupled to a common serving terminal, and automatically generating a repair ticket when the two or more subscriber loops that experienced the respective performance degradations during the first time interval are served from the common serving terminal, the repair ticket representing a possible wideband noise interference condition affecting more than one of the plurality of subscriber loops.
