Abstract
Methods and apparatuses are disclosed for detecting improper connection near the end of an xDSL loop based on separately analyzing the location and levels of time domain signals associated with different transmission bands in an xDSL band plan. In one embodiment, a method is disclosed to separately convert the received test signal data to different sets of time domain data corresponding to different sets of the separate frequency bands, and then to separately analyze the different sets of time domain data to identify an improper connection near the modem.
