La présente invention concerne un ensemble terminaison comprenant une surveillance de port comportant des capteurs d'occupation de port qui acheminent des signaux agrégés au niveau d'un connecteur d'interface pour l'ensemble terminaison. De multiples ensembles terminaisons peuvent être connectés à un dispositif d'agrégation de telle sorte que des signaux d'occupation de port puissent être envoyés à un réseau de surveillance de port. Un ou plusieurs ensembles terminaisons peuvent être disposés sur des plateaux qui sont mobiles (par exemple : coulissants) par rapport à un châssis de manière à former un panneau de communication. Les composants de surveillance de port peuvent être intégrés à l'ensemble terminaison.
