Abstract

LA TENSION DE ALIMENTACION DE ABONADO APLICADA AL CIRCUITO DE CONEXION DE ABONADO (SLIC) DEPENDE DE LA LONGITUD DE LA LINEA DE ABONADO (TL). PARA GENERAR LA SEÑAL DE LLAMADA SE CONECTA UNA TENSION CON POLARIDAD (+UZ) OPUESTA A LA POLARIDAD DE LA TENSION DE ALIMENTACION (-UB). PARA QUE LA TENSION DE LA SEÑAL DE LLAMADA SEA INDEPENDIENTE DEL VALOR, DEPENDIENTE DE LA LONGITUD, DE LA TENSION DE ALIMENTACION, SE GENERA LA TENSION (+UZ) CON UN REGULADOR DE CONEXION (OP1,OP2,OP3), QUE MANTIENE UNA TENSION DIFERENCIAL CONSTANTE.
