Abstract

The system is constituted by a wired logic included in a signalling unit, which also has a microcomputer. This logic is connected on the one hand to the incoming and outgoing signalling junctions of a connection network and on the other to a programmed peripheral marking unit by means of which a central computer supplies correspondence data between an incoming junction channel and an outgoing junction channel.
