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： A DSL management system predicts achieving improved performance of a DSL line. The system obtains a current state of performance of the line before optimization, and a target state of performance of the line after optimization. The system further obtains a measure of line characteristics of the line, and identifies a subset of records associated with optimizing performance of a subset of DSL lines having a similar measure of line characteristics as the line for which achieving improved performance is being predicted. A probability that performance of the line will be optimized from the current state to the target state is calculated, based on a statistical analysis of the identified subset of records that detects instances when a DSL optimizer previously has optimized the performance of the subset of lines from a same or similar state as the current state to a same or similar state as the target state.

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.

摘要： Methods, techniques, computer program products, apparatus, devices, etc., used in connection with DSL Management Interfaces, significantly improve the management capabilities of a DSL network and/or improve testing relating to DSL equipment and services by permitting better control and operation of a DSL system, including implementation of timestamping for more accurate measurement, monitoring and control of a system. Timestamping further allows customized data collection techniques, where a DSL line can be measured or monitored at intervals whose frequency depends on the line's stability. Moreover, data parameter read and control parameter write operations are presented in conjunction with the use of timestamping. Also, control and operation of a DSL system is enhanced by implementing bit-loading that minimizes, eliminates or otherwise mitigates the amount by which the SNR margin per tone exceeds a maximum SNR margin quantity, where such bit-loading can be selected through an appropriate interface.

摘要： A DSL management system predicts achieving improved DSL line performance before a DSL optimizer in the DSL management system optimizes performance of the DSL line. The system obtains a current state of performance of the DSL line before optimization, and a target state of performance of the DSL line after optimization. The system further obtains a measure of the DSL line characteristics of the DSL line, and identifies, from among a plurality of records of performance information correspondingly associated with a plurality of DSL lines, a subset of the records of performance information correspondingly associated with a subset of DSL lines having a similar measure of the DSL line characteristics as the DSL line for which achieving improved DSL line performance is to be predicted. The system obtains a probability that the DSL optimizer will optimize the performance of the DSL line from the current state of performance to the target state of performance, based on a frequency with which the identified subset of records of information associated with the subset of DSL lines indicates that the DSL optimizer previously has optimized the performance of the subset of DSL lines from a same or similar state as the current state of performance to a same or similar state as the target state of performance.
