ABSTRACT:
A communications system includes a plurality of interfaces (20) each of which can receive and/or transmit data to a common transmission network (21). Each interface (20) transmitting data to the network (21) attaches a classification code to the transmitted data, and each interface (20) receiving data from the network (21) retrieves the classification code and restricts access to the associated data in dependence upon that classification code. The invention alleviates the need to employ "secure" and "clear" communications networks in parallel, and is especially applicable to aircraft communications.
