Abstract

L'invention concerne un ensemble plateau de télécommunications qui peut comprendre une structure de support comprenant une saillie d'alignement ; un plateau de télécommunications ayant un axe longitudinal et comprenant une encoche d'alignement, un agencement de liaison reliant de manière rotative le plateau de télécommunications à la structure de support autour d'un axe de pivotement, la saillie d'alignement étant reçue à l'intérieur de l'encoche d'alignement de telle sorte que le plateau de télécommunication ne peut être relié qu'à la structure de support dans une première orientation autour de l'axe longitudinal, et un agencement de positionnement permettant la rotation du plateau de télécommunications, par rapport à la structure de support, entre une position fermée et une position ouverte, l'agencement de positionnement fournissant une résistance à la rotation du plateau de télécommunications entre les positions de rotation ouverte et fermée.
