Digital switching system
First Claim
1. A system for digital switching between n junctors, n being a whole number greater than 1, which receive and deliver speech and signaling data, said system being provided with direct connections between the junctors so as to ensure that each of the n junctors is capable of directly exchanging data with the other junctors of the n junctors, wherein each of the n junctors is provided with its own decision and switching unit to manage exchanges of the data with the n-1 other junctors, formed by a control unit with fault detectors and by a digital connection network controlled by the aforesaid control unit.

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.
