Abstract

La présente invention concerne un procédé et un appareil permettant un agencement d'emplacements dans un équipement de technologie SDH (hiérarchie numérique synchrone). Un emplacement de carte de service et un emplacement de carte de fonction de puissance sont agencés de manière compatible dans un emplacement compatible d'un panneau arrière ; lorsque l'emplacement compatible reçoit une carte de fonction de puissance, la carte de fonction de puissance est connectée à un bus de carte de fonction de puissance fourni par l'emplacement compatible ; lorsque l'emplacement compatible reçoit une carte de service, la carte de service est connectée à un bus de carte de service fourni par l'emplacement compatible. La structure d'agencement d'emplacements de l'équipement SDH fournie par la présente invention est mieux conçue et plus compacte, et permet à l'équipement SDH de ne pas affecter la capacité d'accès de service dans le cas de prise en charge d'une carte de fonction de puissance. Elle constitue donc un complément avantageux au mode d'agencement antérieur.
