Abstract

The invention relates to a digital communication system for a network operating in half-duplex mode and comprising a bus for speech and a bus for service messages. Since the latter are of considerable volume, it is advantageous to unburden the bus transporting the marshalling messages by sending a part of these messages via the speech bus and to thus ensure real-time transmission of the information. In order to be able to distinguish the two types of information on reception, the invention provides for the placing, at the level of each service message transmitted in place of a silence, of a recognition sign consisting of a code individual to the speech encoding law, and which is unobtrusive since it is unused or redundant as regards the transmission of speech. The invention provides preferentially for the use of the encoding law A which possesses not merely a redundancy, but what is more, a redundancy in the encoding of silences. The invention applies in particular to air traffic control. <IMAGE>
