The present invention is an improved data terminal for use in communication and testing of telephone lines which data terminal is operated by a 16-bit microprocessor operating under control of MS-DOS 5.0 program. The data terminal with operating computer and large plurality of telephone test functions is fully contained in a hermetically sealed, lightweight housing to enable easy field handling through data send and receive operations as well as the multiple of telephone line test operations. Power saving aspects of the invention include automatically adjusted LCD backlight control and LCD adjustment caused by large or abrupt temperature changes in the field. The system uses a large microprocessor with EPROM and random access memory with field programmable gating arrays offering virtually thousands of different gate logic decisions.

La présente invention est un terminal utilisé pour les communications et la vérification des lignes téléphoniques. Ce terminal est piloté par un microprocesseur 16 bits contrôlés par un programme MS-DOS 5Ø Le terminal et son ordinateur connexe, qui comporte un grand nombre de fonctions de vérification de lignes téléphoniques, prennent entièrement place dans un boîtier hermétique léger qui permet de les utiliser facilement sur place pour transmettre et recevoir des données et pour effectuer les multiples opérations de vérification de lignes téléphoniques. Le terminal de l'invention est doté de plusieurs dispositifs économiseurs d'énergie, dont un réglage automatique de l'éclairage de l'afficheur à cristaux liquides et un réglage de cet afficheur en cas de grande variation ou de variation brusque de la température ambiante. Le système utilise un microprocesseur puissant à mémoires EPROM et RAM avec des réseaux de déclenchement programmables sur place offrant virtuellement des milliers de décisions de déclenchement différentes.
