Abstract

L'invention concerne un dispositif de test de lignes téléphoniques. Ce dispositif comprend essentiellement deux circuits d'entrée 11 et 12 destinés à être branchés aux deux conducteurs d'une ligne téléphonique bifilaire, une source de tension 22, un circuit de mesure 17, une unité de commande 16, et un convertisseur analogique-numérique 20 qui présente sous forme numérique les valeurs mesurées. Application à là maintenance des réseaux téléphoniques.
