The function of the arrangement consists in connecting the terminal to the supply system (switching-on) and in loading therein the programs required for its operation (initialization) in the absence of the operator. A call signal (RING) sent by the remote computer produces the switching-on and initialization of the terminal. When the initialization has been completed, the terminal sends a ready-to-receive signal on the line and the conversation begins. At the end of the transfer of data, the telephone line is disconnected without the need to switch off the terminal . This is switched off after all the home processing operations (on the data received from the computer) are at an end. Finally, the terminal returns to the initial state, that is it is ready to switch on and be initialized on the arrival of the signal RING.
