Abstract
This invention relates to a method of managing a digital subscriber line, where classification for a potential fault on a line is generated. The invention continuously measures the signal to noise (SNR) margin on the DSL line, and compares the measurements to predetermined conditions based on SNR margin characteristics associated with a population of good lines. Once the SNR margin measurements fail to meet the predetermined conditions, the line is flagged as experiencing a potential fault. Further measurements from weather sensors are gathered, and correlated with the SNR margin characteristics. The resulting correlation is used to generate a classification of a potential fault on the line. This can then be used to more specifically direct diagnosis and further testing.
