Device for checking the function of a cable shield of a wired communication connection

Abstract

A device for checking the function of a cable shield of a wired communication connection between two communication partners which communicate by the wired communication connection, including a first electrical circuit and a second electrical circuit. The first electrical circuit is provided in at least one of the communication partners, by which a test voltage can be applied to the cable shield. The second electrical circuit provided in one or another of the communication partners, which feeds the applied test voltage to a measured value acquisition unit, which takes a measurement of the test voltage and generates an error signal if a test voltage has been measured that is outside a permissible value range or outside one of a plurality of permissible value ranges.
