Abstract

Sistema de supervisión y análisis de comportamiento funcional para sistema conmutador controlado por programa almacenado. Una herramienta de prueba y diagnóstico para sistemas conmutadores (11) de telecomunicación controlados por programa almacenado capta la ocurrencia y temporización de "sucesos'' (17, 18, 19) originados por acciones de abonados y por acciones que ocurren dentro de bloques de soporte lógico en el sistema conmutador (11) de telecomunicación. Los datos relacionados con los sucesos captados (17, 18, 19), así como una indicación de su posición, se almacenan en una gran memoria intermedia (25). Entonces, los datos almacenados se usan para analizar los sucesos (17, 18, 19) para el diagnóstico y corrección de la causa del fallo así como para recrear la misma secuencia y temporización de sucesos (17, 18, 19) en un período posterior a fin de probar las correcciones que se han efectuado para asegurar que ellas eliminan la causa del estado de fallo.
