Abstract
SE PROPORCIONA UN MEDIO PARA PROBAR LINEAS TELEFONICAS, EL MEDIO INCLUYE UN DETECTOR DE DESCONEXION DE TIMBRE DE CORRIENTE DE CIRCUITO CERRADO Y UN REVELADOR QUE CUANDO ESTA ACCIONADO ES UTILIZADO PARA INTERRUMPIR LA CORRIENTE NORMAL PARA PROPORCIONAR LA FINALIZACION DE LA SEÑAL DE LLAMADA, Y EN DONDE DICHO RELEVADOR ES TAMBIEN OPERATIVO EN UN MODO DE PRUEBA PARA CONMUTAR DESDE DICHO DETECTOR DE TIMBRE DE CIRCUITO CERRADO HACIA UN COMPARADOR, EL CUAL FUNCIONA COMO UN DETECTOR DE MODO DE PRUEBA. EL MEDIO PUEDE INCLUIR TAMBIEN UN SEGUNDO RELEVADOR, EL CUAL CUANDO EL CIRCUITO ESTA EN UN SEGUNDO MODO DE PRUEBA ES SIMULTANEAMENTE ACCIONADO CON EL PRIMER RELEVADOR, ESTANDO EL SEGUNDO REVELADOR CONECTADO A UN CAPACITADOR DE CAMPANA, CUYA TASA DE DESCARGA PUEDE SER MEDIDA POR DICHO CAPACITADOR, Y EL COMPARADOR DE SALIDA ESTA SECUENCIALMENTE MONOTORIZADO PARA PROPORCIONAR INFORMACION, COMO DE LA CONDICION DE AISLAMIENTO Y CON RESPECTO AL CAPACITADOR DE CAMPANA Y CONEXION TERMINAL.
