<p>The invention relates to a circuit configuration for remote feeding of a local component (21) which is connected to the exchange component (20) of an out-of-area switching device of a message transmission system via a transmission line (1, 2). Said device comprises a d.c. converter (14, 15) which preferably comprises a transducer-transformer (14). Said d.c. converter (14, 15) converts the voltage of a remote feeding voltage source which can be connected to a transmission line in the exchange component. Subscriber terminals which are connected to the local component (21) are thereby fed. A monitoring device (23) is provided in the local component (21). The current electrical power requirement of the local component (21) and the subscriber terminals connected thereto can be determined by said monitoring device (23). The remote feeding voltage source can be controlled by means of a transmission device which is connected to the transmission line (1, 2) by means of the monitoring device (23) on the basis of the electrical power requirement thus determined.</p> |
