Abstract

In the network termination device (NT), the voltage (US) and the current (I) of the connected line (L) are measured and an error handling is initiated when a voltage (US) is less than a threshold voltage (SU) that corresponds approximately to half of the centrally fed voltage (U). During said error handling, the network termination device (NT) is influenced, while taking the currently measured current (I) into account, in such a way that the measured voltage (US) is greater than the threshold voltage (SU), e.g. when activating a function (F), other functions (F), for example, having a large current demand can also be deactivated.
