Abstract
EL INVENTO ES UN DISPOSITIVO DE SEÑALIZACION POR VIA LUMINOSA PARA INSTALACION TELEFONICA, CUYOS ABONADOS SON DOTADOS DE POSTES ANALOGICOS, ASI COMO LOS POSTES EQUIPADOS A ESTE EFECTO. CADA POSTE TELEFONICO (4) ESTA EQUIPADO EN PARALELO CON UNA LAMPARA DE MENSAJE (59) EN SERIE CON UNA RESISTENCIA (60), POR UNA PARTE, Y CON UN CONDENSADOR (61), A LA SALIDA DEL PUENTE RECTIFICADOR (51) DEL POSTE, POR LA OTRA PARTE. LA SEÑALIZACION DE MENSAJE SE REALIZA POR LA ACCION DE MANDO (3) DEL EQUIPAMIENTO CENTRAL SOBRE EL INYECTOR DE SEÑALES DE LLAMADA (36) ASIGNADO AL POSTE, DE FORMA QUE LE HACE TRANSMITIR UNAS SEÑALES CADENCIALES DIFERENTES DE LAS SEÑALES CADENCIALES DE LLAMADA POR LA DURACION MAS CORTA DE LAS FASES DE EMISION DE LA SEÑAL Y QUE PERMITEN EL ENCENDIDO DE LA LAMPARA.
