Abstract

L'invention concerne un dispositif de communication qui comprend un boîtier et une structure de connexion inter-carte. La structure de connexion inter-carte forme un système de communication disposant d'une fonction de commutation et comporte des cartes de service, des cartes de commutation et un fond de panier. Dans la structure de connexion inter-carte, le fond de panier est parallèle à la direction de ventilation dans le dispositif de communication. Les cartes de service sont connectées verticalement au fond de panier et les cartes de commutation sont connectées au fond de panier au moyen de multiples connecteurs. L'invention concerne également une structure de guidage de carte du dispositif de communication.
