Given the prerequisite of a division of a subscriber line circuit into a high-voltage portion and a signal processor that defines the transmission-oriented properties, voltages arising at significant locations of the receiving branch and of the transmitting branch of the signal processor as a result of supplied and reflected sine signals are taken via a digital interface and specific transmission properties such as reflection attenuation and hybrid transfer attenuation are calculated therefrom on the basis of a correlation.
