Abstract
The present disclosure relates to circuits for detecting a line short circuit and/or a line interruption in a differentially operated line network, comprising at least one control circuit configured to control at least one common-mode signal of the differentially operated line network vis-à-vis a predefined common-mode signal variable and to indicate a line short circuit and/or a line interruption in the differentially operated line network if at least one control or controlled variable of the control circuit exceeds a predefined threshold value.
