<p>A method for detecting radio frequency interference, includes: obtaining parameters of at least two digital subscriber line pairs (S100); according to the parameters, detecting a sub-channel in which radio frequency interference existing in each digital subscriber line pair of the at least two digital subscriber line pairs (S102); counting the line pair number of the digital subscriber lines suffering radio frequency interference on the same sub-channel, if the number of the line pairs appearing radio frequency interference on the sub-channel is greater than a preset threshold, or if the ratio of the number of the line pairs appearing radio frequency interference on the sub-channel to the line pair number of the at least two digital subscriber line pairs is greater than a preset threshold, radio frequency interference exists at the frequency corresponding to the sub-channel (S104). Also a device and system for detecting radio frequency interference are provided. The method, device and system for detecting radio frequency interference can detect the radio frequency interference existing in XDSL.</p> |
