METHODS AND APPARATUS TO DETECT AN IMBALANCED SUBSCRIBER LINE IN A DIGITAL SUBSCRIBER LINE (DSL) SYSTEM |
摘要 |
Methods and apparatus to detect an imbalanced subscriber line in a digital subscriber line (DSL) system are disclosed. An example method comprises identifying a contiguous set of performance parameters in a plurality of performance parameters for respective ones of a plurality of DSL sub-carriers of a subscriber line associated with a DSL modem, the identified set have values representative of degraded performance and corresponding to an operating frequency of a geographically proximate AM interference source. The example method further comprises comparing a number of DSL sub-carriers contained in the identified set with a threshold to determine whether the subscriber line has an imbalanced condition.
