Abstract: A method for determining current return path integrity in an electric device with a plurality of signal lines and supply lines. A library with at least one reference signal pattern of a near end crosstalk signal on a defined signal line arising from an input signal on another defined signal line is provided, a predetermined signal to a selected signal line of the electric device is applied, the near end crosstalk signal on at least one further signal line of the electric device is detected, said near end crosstalk signal is compared with the corresponding reference signal pattern from the library, and if there is a deviation between the near end crosstalk signal and the corresponding reference signal pattern, an information that there is any defect in the electric device is displayed.

Abstract: Network power fault detection. At least one first network device is instructed to temporarily disconnect from a power supply path of a network, and at least one characteristic of the power supply path of the network is measured at a second network device connected to the network while the at least one first network device is temporarily disconnected from the network.
