Abstract

EL DISPOSITIVO ESTA CONECTADO A LA LINEA TELEFONICA. ESTE TIENE MEDIOS PARA SUMINISTRO DE POTENCIA (16) CON UNA IMPEDANCIA DE ALMENOS 5 MEGAOHMIOS A TRAVES DE LA LINEA TELEFONICA (10,12), MEDIOS DE AMPLIFICACION DE SEÑAL (20) SOBRE LA LINEA, SENSORES DE SEÑAL DE REALIMENTACION (22,24,26) PARA DETERMINAR CUANDO LA FRECUENCIA DE LA SEÑAL AMPLIFICADA ESTA DENTRO DE UNA BANDA DETERMINADA, Y MEDIOS DE DETECCION DEL BLOQUEO (28) PARA DAR UNA SEÑAL DE SALIDA CUANDO LA FRECUENCIA DE LA SEÑAL ESTE DENTRO DE LA BANDA PREFIJADA DURANTE UN TIEMPO PREFIJADO. EL DISPOSITIVO SE PUEDE MEJORAR MEDIANTE UNA BATERIA DE CENTRALITA TELEFONICA PARA TRANSFORMAR LA TENSION DE LA BATERIA EXTERIOR EN LA TENSION DE SUMINISTRO.
