ABSTRACT:
A driver and receiver circuit includes at least one output terminal for connecting a line connection. The circuit further includes a voltage supply arrangement connected to the at least one output terminal and a current measuring arrangement connected to the at least one output terminal. The current measuring arrangement is designed to detect a current at the at least one connecting terminal and to generate a current measurement signal dependent on said current. The driver and receiver circuit further includes a control circuit, to which the current measurement signal is fed, and at least one monitoring circuit. The monitoring circuit is designed to detect the current at the at least one connecting terminal and to output an error signal if the current lies above a predetermined threshold value for a time duration which is longer than a predetermined first time duration.
