<p>21 This telephone switching system is formed on the basis of a switching network (1) intended to switch message information by interconnecting input circuits (11, 21, 31, 41, 51 and 61) provided with programmedlogic units (81, 82, 83, 84, 85 and 86) called input inputs. It is remarkable for the fact that, among these programmed-logic units, it incorporates for the purpose of transmitting control information connecting circuits formed by loops (100, 101 and 102) in which control circuits (2) of the switching network (1) are inserted.</p> |
