Abstract
A method provided in one example includes inserting a first common-mode signal into a first communication channel from a communication node, monitoring differential-mode noise in at least one communication channel due to the first common-mode signal, determining whether the differential-mode noise is acceptable, and generating a user notification if the differential-mode noise is not acceptable. In further embodiments, the at least one communication channel comprises one or more communication channels adjacent the first communication channel, and the method further includes determining whether the differential-mode noise due to the first common-mode signal is acceptable on the adjacent channels. In further embodiments, the method comprises sending a port identifier through the first communication channel before initiating the insertion. In more specific embodiments, the first common-mode signal comprises a signature that distinguishes the differential-mode from data on the at least one adjacent communication channel.
