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.
