Abstract
Analog voltages are collected by scanning the two wires of a subscriber line; the values are subjected to an analog-digital conversion and fed to a microprocessor (MC) which computes the desired measuring values from the results of said conversion. Thus, from a single measuring operation performed at two measuring points, nine different voltage values can thus be obtained including dc, ac and external voltages between each wire and ground and between the two wires.
