Abstract: A digital switching system for establishing safety communications between N junctors is intended to guard against the potential danger of generalized failure which lies in the use of a central control unit and digital connection network for carrying out exchanges of information between junctors. Accordingly, each junctor is directly coupled to the N-1 other junctors of the system and is provided with its own control unit and its own digital connection network in order to enable said junctor itself to select the particular information which it is desired to receive from the N-1 other junctors. This system is primarily applicable to air and ocean traffic control.
