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 differential mode signal probes onto two conductors of a Digital Subscriber Line (DSL line); means for measuring a common-mode rejection ratio (CMRR) of the differential mode signal probes; means for measuring impedance of the differential mode signal probes; and means for identifying which of an asymmetric fault condition or a symmetric fault condition is present on the line based on both: (a) the measured CMRR of the differential mode signal probes and (b) the measured impedance of the differential mode signal probes.
