A method and apparatus for testing for correct connection together of circuit elements in a circuit (10) formed of a plurality of redundant circuit portions (12). A coded signal is generated at afirst circuit element (14) and transmitted upon a signal path believed to connect the first circuit element with a second circuit element (16). If the coded signal is detected at the second circuit element, the correct connnection of the first circuit element togehter with the second circuit element is verified. Because a coded signal is generated, the correct connection between the circuit elements can be verified even when the signal path connecting the first and second circuit elements is formed of an optical, or other non-electrical, coupler.
Cette invention concerne un procédé et un appareil pour la vérification de la connexion entre des éléments d'un circuit (10) constitué d'une pluralité de parties de circuit redondantes (12). Un signal codé est produit au niveau d'un premier élément de circuit (14) et transmis sur un trajet de signal supposé relier le premier élément de circuit à un second élément de circuit (16). Si le signal codé est détecté au niveau du second élément de circuit, cela prouve que la connexion est correcte entre le premier élément de circuit et le second élément de circuit. Etant donné qu'un signal codé est produit, il est possible de vérifier que la connexion est correcte même lorsque le trajet de signal reliant les premier et second éléments de circuit est constitué d'un coupleur optique ou d'un autre type, non électrique.
