Abstract

L'invention concerne la surveillance d'une ligne téléphonique La coupure 19 ou le court-circuit 18 déséquilibrent le pont 13, et ce déséquilibre persiste après inversion des polarités par le détecteur 16. Au contraire, si le circuit 3-4 est normal, la fermeture du contact 1 déséquilibre le pont 13, mais ce déséquilibre cesse dès l'inversion des polarités. Application : détection des défauts sur la ligne 3-4, et sélection par rapport aux signaux normaux d'utilisation.
