摘要： Methods and systems for twisted pair telephone line diagnostics based on patterns of line data occurring over time. An observed data distribution is classified as periodic or based on modeled distributions previously determined to correspond to a known line activity, fault type, or fault location. A disruption or parameter value pattern is classified through statistical inference of operational and performance data collected from the line. Where the disruption and/or parameter value(s) correlate with a time the customer is at the customer premises, an inference is made that the line fault causing the disruption is more likely at the CPE than at the Central Office. Where the disruption distribution is classified as being a result of human activities initiated on the line, a fault condition associated with the activity is inferred. Where a disruption pattern is correlated with human initiated plain old telephone service (POTS), a micro-filter problem is inferred for the line.

摘要： In accordance with embodiments disclosed herein, there are provided methods, systems, mechanisms, techniques, and apparatuses for diagnosing and optimizing vectored DSL lines. For example, in one embodiment, such a system includes an interface to a first subset of a plurality of digital communication lines allocated to a vectored group and to a second subset of the plurality of digital communication lines which operate external to the vectored group; a Dynamic Spectral Management server (DSM server) to analyze the vectored group by performing the following operations for each of the plurality of digital communication lines in the vectored group: measuring a mitigated noise level for the digital communication line with crosstalk cancellation active, measuring a non-mitigated noise level for the digital communication line with crosstalk cancellation inactive, and comparing the mitigated noise level measured on the digital communication line with the non-mitigated noise level measured on the digital communication line. In such an embodiment, the DSM server of the system further issues optimization instructions based on the analysis. For example, by issuing optimization instructions for the vectored group, for lines external to the vectored group, or for both.

摘要： Methods and systems to improve accuracy and fault detection capability of automated line diagnostics through at least one of: joint processing of SELT and DELT data; comparisons of relative strengths of peaks and/or dips to envelope and/or peaks to dips in a time domain echo response; and iterative diagnostics whereby an echo response is adjusted through signal processing techniques, for example to remove lengths of straight line, between successive performance of a detection algorithm. More than one of the diagnostic systems and methods described herein may be employed in combination to improve accuracy and fault detection capability. For example, where SELT and DELT data are jointly processed, analysis of the SELT data may employ the ratio tests described in the context of a SELT diagnostic routine. Similarly, the SELT diagnostics method assessing relative strengths of peaks and dip in an echo response via ratio tests may be combined with iterative adjustment of the echo response.
