Abstract
The development of a network for emergency calls for highways of up to several hundred kilometers is discussed. The system has a bus structure allowing digital transmission of voice and data at low speed and with enough quality for this kind of application. The overall architecture and the operational features of this network are described. Particular attention is given to voice encoding, the communication protocol, and the message structure.<>
