Qualifying a subscriber loop for xDSL transmission can be done in many ways. Amongst all ways, methods that don’t require an expensive truck-roll to the customer are preferred. In this paper we provide a method for an intelligent automated interpretation of reflectometric 1-port measurements at the central office. First we will focus on how reflectograms(More)
− The Expert System, which is described in this paper, constitutes a fundamental unit of a general measurement system, which is capable to perform an xDSL (arbitrary Digital Subscriber Line) loop qualification by means of time-domain reflectometry (TDR). The goal of the measurement system is to estimate the theoretical channel capacity of the local loop,(More)
