    Abstract: In accordance with embodiments disclosed herein, there are provided apparatus, systems, and methods for identifying cable-level faults in a copper plant of a DSL system. For example, such means may include identifying a group of Digital Subscriber Lines (DSL lines) within a common cable; determining a baseline of physical line characteristics for each of the DSL lines in the group; collecting current physical line characteristics for each of the DSL lines in the group; determining a physical line characteristics delta for each of the DSL lines in the group by comparing the current physical line characteristics to the baseline of physical line characteristics for each of the respective DSL lines; and indicating a defect in the common cable based on a quantity of the DSL lines in the group for which the respective DSL line's physical line characteristics delta exceeds a threshold. Other related embodiments are disclosed.

    Abstract: 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.

    Abstract: In accordance with embodiments disclosed herein, there are provided apparatus, systems and methods for implementing DSL line fault determination and localization via SELT, DELT, and MELT diagnostics. For example, such a system or computer implemented method may include means for: receiving Metallic Loop/Line Testing (MELT) test output from applying a MELT test to a DSL line; receiving Dual-End Line Testing (DELT) test output from applying a DELT test to the DSL line; receiving Single-Ended Loop Testing (SELT) test output from applying a SELT test to the DSL line; determining one or more faults are present on the DSL line by comparing the MELT test output, the DELT test output, and the SELT test output; and localizing the one or more determined faults by comparing the MELT test output, the DELT test output, and the SELT test output. Other related embodiments are disclosed.

    Abstract: In accordance with embodiments disclosed herein, there are provided apparatuses, systems and methods for implementing upstream power control for DSL communications. For example, such a system may include means for: dividing a plurality of DSL lines into a first group of DSL lines and a second group of DSL lines based on characteristics common to each of the DSL lines within the respective first and second groups; determining attainable upstream data rates for the first and second groups of DSL lines according to the characteristics of each group; selecting upstream power control parameters to apply to each of the first and second groups of DSL lines based on the attainable upstream data rates determined; and instructing the DSL lines of the first and second groups to adopt the selected upstream power control parameters. Other related embodiments are disclosed.

    Abstract: 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.

    Abstract: 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.
