Abstract
L'INVENTION CONCERNE L'ALIMENTATION DES LIGNES TELEPHONIQUES. UN CIRCUIT D'ALIMENTATION COMPREND UNE PARTIE A PLUS HAUTE TENSION (1) ET UNE PARTIE A PLUS BASSE TENSION (2) DANS LAQUELLE S'EFFECTUE LA PROGRAMMATION DE LA CARACTERISTIQUE D'ALIMENTATION EN COURANT. POUR PERMETTRE LA PROGRAMMATION, UN PREMIE COMPOSANT RESISTIF PROGRAMMABLE (RA) EST BRANCHE PRATIQUEMENT EN PARALLELE AVEC UN CONDENSATEUR (C1), POUR DETERMINER LA RESISTANCE D'ALIMENTATION POUR DE FAIBLES COURANTS DE LIGNE. UN ELEMENT DE LIMITATION DE TENSION (7) AYANT UNE TENSION DE REFERENCE PROGRAMMABLE EST CONNECTE EN SERIE AVEC UN SECOND COMPOSANT RESISTIF PROGRAMMABLE (RB), ET CE CIRCUIT SERIE EST BRANCHE PRATIQUEMENT EN PARALLELE SUR LE MEME CONDENSATEUR (C1), DANS LE BUT DE DETERMINER LE COURANT DE LIGNE LIMITE ET LA RESISTANCE D'ALIMENTATION DU CIRCUIT AU MOMENT DE LA LIMITATION. APPLICATION AUX CIRCUITS D'INTERFACE DE LIGNE D'ABONNE
