Abstract

Dispositif pour le contrôle de connexions électriques, notamment en télécommunication pour le test de circuits d'abonnés ou de lignes réseaux dans un autocommutateur. Le contrôle des circuits est effectué en permanence par un circuit de contrôle intégré dans l'autocommutateur. Il comprend un circuit d'émission constitué par le circuit de tonalités de l'autocommutateur et un circuit de mesure raccordé au termineur de l'autocommutateur. Application : télécommunications.
