In present data bus systems the problem of the "babbling idiot" arises, in other words a situation wherein a terminal arbitrarily starts to transmit although a signal is already present on the bus, thus blocking the bus. According to one exemplary embodiment of the present invention, a determination as to whether the data bus is available is made within the terminal. If it has been determined that the transmitter is transmitting although the data bus is not available, a fault is present and the sender is switched off by means arranged within the terminal.
