Abstract
A transmission configuration between a main station and a local station consists of a line which permits supplying of direct voltage power for stations from a source within the main station. A rectifier bridge is installed in such a manner that suitable polarization of the receiver can be achieved, regardless of the branching direction for wires comprising the line. Groups of unipolar current impulses are superimposed upon the supply voltage along the line by two generator units (K.sub.44, 40 and K.sub.50, 46) within the main station and a generator (K.sub.102, 100) within the local station. The respective polarities of impulses sent to and from the main station and the local station are such that said impulses can flow through rectifier bridges within local stations.
