Provided are a method, device and system for detecting a disturbing line. In the case that wiring disorder exists among a plurality of DSLAMs, if a first DSLAM is an interference source of a second DSLAM, based on an SELT signal sent from the first DSLAM over one or more preset sub-carriers, an interference signal is made to exist on a line corresponding to the one or more preset sub-carriers, a difference value between a line detection parameter value to which the second DSLAM corresponds over the one or more preset sub-carriers and a line detection parameter value corresponding to sub-carriers adjacent to the one or more sub-carriers in the second DSLAM is acquired, a sub-carrier frequency of the one or more difference values reaching a preset threshold value is acquired, and the line corresponding to the sub-carrier frequency is identified as a disturbing line. Thus, a disturbing line can be detected immediately, effectively improving the transmission rate of the channel and making the DSLAM outlet rate low and ensuring the high stability of the network. |
