Abstract

L'invention permet de contrôler rapidement la qualité des capsules des postes téléphoniques sans avoir recours aux mesures acoustiques de téléphonométrie qui requièrent un équipement et un environnement spécialisés. Le haut-parleur HP1 coopère avec le microphone 4 du poste 3, le haut-parleur HP2 avec le récepteur 5. Le transformateur T1 est associé à l'accès de ligne du poste téléphonique, le transformateur T2 aux haut-parleurs. Les transformateurs sont reliés ensemble par une boucle de réaction commutable comprenant un amplificateur opérationnel à gain variable AMP1 et un amplificateur opérationnel à gain fixe AMP2. On agit sur le potentiomètre P jusqu'à l'accrochage. Celui ci a lieu pour un gain déterminé correspondant à des valeurs données des éléments du poste. Il se traduit par l'allumage d'une diode luminescente LED. Si un de ces éléments est défectueux, l'accrochage ne peut pas se produire pour la valeur de gain normalement prévue. L'invention trouve son application, notamment dans la maintenance des postes téléphoniques.
