Abstract

SISTEMA DE COMUNICACION INTEGRADO.COMPRENDE UNA RED TELEFONICA DE BANDA ESTRECHA Y UNA RED ANCHA PARA LA TRANSMISION DE IMAGENES ANIMADAS; CON CENTRALES DE BANDA ANCHA CONECTADAS ENTRE SI Y CON LOS EQUIPOS DEL ABONADO, EN DONDE UNA LLAMADA DE VIDEO NO PUEDE ESTABLECERSE HASTA QUE SE HAYA ESTABLECIDO LA LLAMADA TELEFONICA ASOCIADA. LAS CENTRALES DE BANDA ANCHA ESTAN INTERCONECTADAS POR CANALES DE SEN/ALIZACION COMUN A TRAVES DE LOS CUALES SE INTERCAMBIA LA INFORMACION DE SEN/ALIZACION REQUERIDA PARA ESTABLECER O LIBERAR LAS LLAMADAS DE VIDEO, Y PORQUE CADA UNO DE LOS EQUIPOS DE ABONADO (1, 2, ... N) ESTA ASIGNADO A UN CIRCUITO DE TONO PARA TRANSMITIR UNA SEN/AL DE PRUEBA QUE CAE DENTRO DE LA BANDA DE VOZ, UTILIZADA PARA COMPROBAR, ANTES DEL ESTABLECIMIENTO DE LA LLAMADA DE VIDEO, SI HA SIDO ESTABLECIDA LA LLAMADA TELEFONICA ASOCIADA.
