Abstract

CONMUTADOR DIGITAL DE CENTRAL DE DERIVACION PRIVADA QUE TIENE UN MODULO CENTRAL DE CONTROL Y AL MENOS UN MODULO DE TARJETA DE LINEA. EL MODULO DE TARJETA DE LINEA CONSTA DE UN ACCESO A TRAVES DEL CUAL PUEDEN PASAR SEÑALES DE COMUNICACION AL CONMUTADOR ESTANDO LOS DOS MODULOS (10, 12A-D) ACOPLADOS ENTRE SI POR UNA LINEA GENERAL (13A-13C), CON UN PRIMER CONJUNTO DE LINEAS PARA DEFINIR INTERVALOS SELECTORES, UN SEGUNDO PARA TRANSMITIR SEÑALES DE COMUNICACION ENTRE AMBOS MODULOS, Y UN TERCERO PARA TRANSMITIR INFORMACION DE SEÑALIZACION ENTRE LOS DOS MODULOS, TAMBIEN INCLUYE MEDIOS PARA SELECCIONAR UN INTERVALO SELECTOR DEL MODULO, CON LO QUE UNA SEÑAL DURANTE TIEMPO SELECCIONADO DIRECCIONA DICHO MODULO.
