Abstract

La présente invention concerne un système de commande à trois calculateurs d'un équipement de commutation. Chacun des trois calculateurs C1, C2, C3 est pourvu des mêmes équipements : une mémoire M1, M2, M3, une interface d'entrée-sortie CBA, une unité de supervision TSM, et il peut accéder à l'un ou à l'autre des bus périphériques A et B. Deux calculateurs peuvent être simultanément actifs et chacun d'eux informe les deux autres de son traitement. L'invention s'applique à la commande de centraux téléphoniques.
