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.
