Abstract
A telecommunication device (11) for vehicle installation is proposed, which is equipped with an HF-transmitting and receiving device (22, 23), with different terminals and with a transmission network (19) between the HF-transmitting and receiving device and the terminals. The telecommunication-specific part of each terminal is physically separated from the actual user part (12, 13, 14) of the terminal, and installed in a central terminal control (15), which is connected with the HF-transmitting and receiving device (22). An efficient, optical transmission network (19) may be provided between the terminal control (15) and the user parts (12, 13, 14) of the terminals. Both the central terminal control (15) and the user parts (12, 13, 14) of the terminals are equipped with an interface unit for the transmission network (19). The telecommunication device (11) is less voluminous than a conventional device with individual terminals, and therefore more suitable for installation in the vehicle.
