DIAGNOSTIC ENGINE FOR DETERMINING GLOBAL LINE CHARACTERISTICS OF A DSL TELECOMMUNICATION LINE AND METHOD USING SAME

摘要

A diagnostic engine for remotely determining global line characteristics of a xDSL telecommunication line from an access node location. The diagnostic engine comprises first, second, and preferably third, measurement means adapted to measure respectively first, second and third line characteristics according to three distinct measurement techniques such as MELT, SELT and DELT. The diagnostic engine further comprises combining means able to combine the measured line characteristics in order to derive thereof global line characteristics or information relative to the physical state of the line as well as possible consequences on DSL service. By combining the three measurements in the combining means, the resulting global line characteristics of the line are improved with respect to performing separately interpretations of the three measurements.
