Method and communication arrangement for the detection of at least one additional communication device which can be connected to at least one subscriber line

摘要

A method and a communication system for the detection of at least one other communication device which can be connected to at least one subscriber connection line is provided. The transmission function of the at least one subscriber connection line is monitored with respect to significant modifications in order to detect at least one additional communication device which can be connected to at least one subscriber connection line. The detection of at least one other communication device connected to the subscriber connection line is displayed if a significant modification of the transmission function is determined. Communication devices and/or listening devices having high input impedance connected to the subscriber connection line may be detected.
