Abstract

Le réseau Internet est prévu tant pour la transmission de données que pour la communication vocale. Un terminal s'articule autour d'un ordinateur personnel (1). Ce terminal comprend, également, un combiné téléphonique (3) dans lequel sont logés un microphone (5), un haut-parleur (7), un lecteur de carte (9) et un circuit de codage des données pour coder les données lues à partir d'une carte par le lecteur de carte (9). L'ordinateur personnel (1) est programmé pour permettre la communication vocale à partir d'un poste à distance à l'aide du combiné (3) et pour transmettre les données codées, lues à partir d'une carte, au poste à distance. Dans un autre mode de réalisation, le rôle de l'ordinateur personnel (1) est assuré par un centre émetteur-récepteur personnalisé.
