ABSTRACT:
The invention pertains to electronic data processing systems including a plurality of removable units that communicate with one another via a bus. To enable disconnection or connection of the removable units without interrupting the operation of the system, each unit includes first means (4) controlled selectively by a maintenance device, to assure the functional isolation of the removable units. The system further includes second means (8, 1B) capable of causing the reception devices (1) of the units to function by a mode that procures increased immunity to interference for them.
