Disclosed is a Maintenance Termination Unit (MTU) for an Integrated Services Digital Network (ISDN). A tone ringer is provided at the end of the customer loop to generate an AC signal. The signal is applied through a transformer and rectifier to charge a capacitor. The resulting voltage across the capacitor causes a normally closed MOS switch to open and disconnect the customer until the capacitor discharges.

On présente ici une Unité de terminaison de maintenance (MTU) pour un réseau à intégration de services numériques (RNIS). Une sonnerie électronique est installée à l'extrémité de la boucle du client pour générer un signal CA. Ce signal est appliqué au travers d'un transformateur et d'un redresseur à un condensateur pour le charger. La tension résultante aux bornes du condensateur provoque l'ouverture d'un interrupteur MOS normalement ouvert et déconnecte le client pendant toute la durée de décharge du condensateur.
