Abstract

The present disclosure relates to a method, a node, a system and a computer program for input impedance measurements in the form of return loss measurements, such as single-ended line testing. The disclosure also relates to a communication system having a near-end terminal and at least one far-end terminal. The near-end terminal is capable of communicating instructions to the far-end terminal in order for the near-end terminal to perform echo impulse response measurements on subsequent states of impedance for comparing, analyzing and for enabling improved localization of faults.
