Abstract

A device for transferring line signaling in a pcm (pulse code modulation) central unit, in b-bit words, between the line signaling unit and the line signaling time channel of each multiplex junction, characterized in that said signals of line are exchanged directly between the line signaling unit and the line signaling channel of the multiplex junctions, without passing through the space-time switch.
