The present invention provides an interfering line detection method, apparatus, and system. When a case of disordered cabling exists among multiple DSLAMs, if a first DSLAM is an interference source of a second DSLAM, based on an SELT signal sent on one or more preset subcarriers by the first DSLAM, an interfering signal exists on a line corresponding to the one or more preset subcarriers, a difference between a line detection parameter value that corresponds to one or more preset subcarriers on the second DSLAM and a line detection parameter value that corresponds to subcarriers respectively neighboring to the one or more subcarriers on the second DSLAM, and a frequency of a subcarrier whose difference of the one or more differences reaches a preset threshold is acquired, where a line corresponding to the frequency of the subcarrier is an interfering line. Therefore, an interfering line can be detected in real time, effectively increasing a transmission rate of a channel and a proportion of services that can be activated for a DSLAM, and ensuring relatively high network stability. |
