Abstract
According to certain aspects, the present invention relates to methods and apparatuses to identify and locate a line-cuts in a loop that may or may not also contain bridgetaps. In embodiments, different bands of SELT signal data are analyzed separately using a TDR method, to effectively detect any potential bridgetaps. In these and other embodiments, by combining information from the separate bands, bridgetap locations and lengths are determined. Methodology is also established to distinguish legitimate line cut or bridgetap signal data from spurious data. According to certain aspects, embodiments of the invention also incorporate baselining, which includes tests to make sure that there are no inconsistencies or imperfections that can corrupt the SELT data.
