Abstract

SISTEMA TELEFONICO CON CONTROL DISTRIBUIDO. COMPRENDE: UNA LINEA DE INTERCOMUNICACION; UNA PLURALIDAD DE ESTACIONES CONECTADAS A LA LINEA DE INTERCOMUNICACION Y UNA PLURALIDAD DE LINEAS TELEFONICAS, INCLUYENDO CADA UNA DE LAS ESTACIONES ELEMENTOS PARA LA TRANSMISION Y RECEPCION DE LA INFORMACION, ELEMENTOS DE CONMUTACION PARA EL ACCESO SELECTIVO DE LOS ELEMENTOS DE TRANSMISION Y RECEPCION A UNA DE LAS LINEAS TELEFONICAS Y A LA LINEA DE INTERCOMUNICACION, Y ELEMENTOS DE CONTROL PARA LA GENERACION Y LA RECEPCION DE LA SEÑAL DE CONTROL Y PARA EL CONTROL DE LOS ELEMENTOS DE CONMUTAICON; Y MEDIOS PARA EL INTERCAMBIO DE LAS SEÑALES DE CONTROL ENTRE ESTACIONES, EN DONDE EL SISTEMA TIENE UN CONTROL DISTRIBUIDO POR MEDIO DE LOS ELEMENTOS DE CONTROL EN CADA ESTACION EN DONDE NO EXISTE LA NECESIDAD DE UN CONTROL CENTRALIZADO. TIENE UTILIDAD PARA CONDUCIR EN PRIVADO LAS CONVERSACIONES DE DIFERENTES ESTACIONES.
