<p>Provided that the subscriber line circuit is divided up into a high-voltage part (SLIC-H) and a signal processor (SLIC-P) which determines the technical transmission characteristics, voltage values occurring due to fed-in and reflected sine-wave signals are recorded via a digital interface at essential points along the reception path and the transmission path of the signal processor, and specific transmission characteristics, such as reflection loss and transhybrid loss, are determined therefrom by means of correlation. …<IMAGE>… </p> |
