ABSTRACT:
A communication system is designed to equip an asynchronous time-division network and to enable terminals linked to the network to communicate in the no-connection mode. The system comprises a ring management device and components distributed among the terminals and interfacing the terminals with a virtual ring for managing the production, reception and transmission of data cells. The ring management device is linked via the network to each of the terminals in order to control the connection/disconnection requests coming from the terminals and to supply information concerning cell routing to the terminals linked to the ring. A terminal has a particular role as a pilot for regulating the rate of the data cells in the virtual ring. Another purpose of the pilot terminal is to eliminate the altered cells. Furthermore, there is provided in each of the terminals a device for limiting its rate to a maximum value.
