Abstract
In order to have the functional modules of a local unit communicate with one another and with an external bus, the device embodying the invention comprises: at least one internal bus of the same type as the external bus per functional module, the latter being coupled to the internal busses so that each module is the sole transmitter on at least one of the internal busses and is a receiver on the other internal busses; an additional internal bus for each external bus of the same type as said internal busses, ensuring the dissemination to the functional modules of data transiting on the external bus; and a coupling module ensuring transfer towards the external bus of the data circulating on the internal busses and destined for another local unit connected to the external bus.
