Abstract
An arrangement is described in which a useful signal is transmitted between at least two device units each having its own power supply circuit, the power supply circuit of at least one of these device units being supplied with power from a preferably electrochemical energy storage means and the power supply circuit of at least a second one of these device units being supplied with power from a power supply mains. In order to enable backup operation of the device unit or device units powered from the power supply mains in case of failure of the power supply mains, at least one of the device units powered from a power supply mains can be coupled, preferably directly, to at least one of the device units powered from an energy storage means for their common power supply from the energy storage means and/or for useful-signal transmission via coupling elements.
