Abstract

SE DESCRIBE UN DISPOSITIVO AUTONOMO (10) PARA VIGILAR EL ESTADO DE UNA LINEA TELEFONICA Y PARA INFORMAR SOBRE EL, PARA USO ENTRE UN CIRCUITO LOCAL DE ABONADO Y LA RED TELEFONICA LOCAL. EL DISPOSITIVO FUNCIONA CON LA CORRIENTE DEL CIRCUITO, CORRIENTE ALTERNA ALIMENTADA DESDE EL EXTERIOR O CORRIENTE CONTINUA A PARTIR DEL LOCAL DEL ABONADO, O MEDIANTE UNA BATERIA INTERNA (61). EL DISPOSITIVO VIGILA DE MANERA PASIVA EL ESTADO DEL CIRCUITO DEL LOCAL HASTA QUE SE DETECTA UNA CONDICION DE ALARMA. CUANDO EL EQUIPO DE COMUNICACIONES DEL LOCAL ES COLGADO O DESCOLGADO, EL DISPOSITIVO DETECTA CONDICIONES DE TENSION Y DE INTENSIDAD DE PUNTA-NUCA NORMALES. SI SE DETECTA UNA CONDICION VALIDA, EL DISPOSITIVO INDICA UN FALLO POTENCIAL DEL CABLEADO DEL LOCAL. EL DISPOSITIVO INFORMA, ENTONCES, DE LA ALARMA MEDIANTE INDICACIONES (11) VISUALES O AUDIBLES, ELECTRONICAMENTE A UN DISPOSITIVO DE VIGILANCIA EXTERNO O MARCANDO AUTOMATICAMENTE UNO DE DOS NUMEROS DE TELEFONOS PREVIAMENTE PROGRAMADOS. SE PUEDE INFORMARDEL FALLO POR LINEA TELEFONICA POR CABLE O MEDIANTE RADIOENLACE (21) A LA OFICINA CENTRAL O A OTRO LUGAR. ADEMAS, CUANDO ESTA CONFIGURADO PARA COMUNICARSE MEDIANTE RADIOENLACE CON LA OFICINA CENTRAL, EL DISPOSITIVO PUEDE SER REPUESTO A DISTANCIA.
