Abstract

LA INVENCION SE REFIERE A UN PROCEDIMIENTO PARA LOCALIZAR UNA INTERRUPCION EN UN ENLACE PARA LA TRANSMISION DE SEÑALES DIGITALES ENTRE UNA PRIMERA ESTACION Y UNA SEGUNDA ESTACION, SOBRE LA BASE DE LOS TIEMPOS DE APARICION DE LOS CAMBIOS DE LA SEÑAL EN EL ENLACE. SEGUN LA INVENCION, EL PROCEDIMIENTO SE CARACTERIZA POR LA GENERACION DE CAMBIOS DE SEÑAL UNA VEZ QUE EL ENLACE HA SIDO RESTAURADO. PREFERENTEMENTE, EL TIEMPO DE LA RESTAURACION SE DETERMINA SOBRE LA BASE DE LAS SEÑALES DE DATOS RECIBIDAS, Y SE SUMINISTRA UNA SEÑAL DE DETECCION AL ENLACE UNA VEZ DETERMINADO EL TIEMPO DE RESTAURACION. LA LOCALIZACION DE LA INTERRUPCION SE REALIZA SOBRE LA BASE DE LA DIFERENCIA DE TIEMPO EXISTENTE ENTRE LA OBSERVACION DE LA RESTAURACION Y LA RECEPCION DE LA SEÑAL DE DETECCION. PARA ESTE PROPOSITO, NO ES NECESARIO CONOCER LA LONGITUD DEL ENLACE.
