Abstract

Abstract Translated from French Le procédé permet de transmettre simultanément, par un multiplexage spatial approprié, des signaux de paroles, des signaux de messages et des signaux de signalisation entre au moins deux stations (ST1, ST2) reliées entre elles par une liaison spécialisée (50). Chaque station comprend au moins une unité de communication U' comprenant un micro (9) un lecteur de badge (16) identifiant une personne, et une tableau synoptique (30) matérialisant la situation géographique des stations d'un même réseau par des moyens de visualisation constitués par des diodes (32, 33) et dont l'état d'éclairement indique l'état de chaque station du réseau pendant une conférence. L'invention s'applique notamment aux systèmes de communications entre une société mère et ses filiales. The method makes it possible to simultaneously transmit, by appropriate spatial multiplexing, speech signals, message signals and signaling signals between at least two stations (ST1, ST2) linked together by a dedicated link (50). Each station comprises at least one communication unit U 'comprising a microphone (9) a badge reader (16) identifying a person, and a synoptic table (30) materializing the geographical location of the stations of the same network by means of display constituted by diodes (32, 33) and whose lighting state indicates the state of each station of the network during a conference. The invention applies in particular to communication systems between a parent company and its subsidiaries.
