Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for examining connections near a modem in a communications system, comprising: receiving test signal data from the line for two or more separate frequency bands; separately converting the test signal data to at least first and second different sets of time domain data corresponding to first and second ones of the separate frequency bands; and separately analyzing the first and second time domain data to identify an improper connection near the m…
