Abstract

In accordance with embodiments disclosed herein, there are provided apparatus, systems and methods for detecting a boundary condition via common mode diagnostics; and to apparatus, systems and methods for detecting a fault condition via common-mode rejection ratio diagnostics. For example, in one embodiment such means include, means for injecting a common mode signal probe onto a first end of a Digital Subscriber Line (DSL line); means for measuring impedance of the common mode signal probe on the DSL line at the first end of the DSL line; means for detecting an impedance anomaly on the DSL line based on the measured impedance of the common mode signal probe; and means for correlating the impedance anomaly on the DSL line to a boundary condition on the DSL line.
