GF82.70-P-3107-02TU Telephone Interface, Function
- with CODE (528) HIGH Class USA


The telephone interface (A34/4) is switched on or off via a discrete wake up line. In the process it reacts to falling voltage (on stand-by the level is max. 5 V) and the duration of the wake up signal.

It is directly wired to the portable telephone bracket for voltage supply and signal transmission.
Control data coming in from MOST (Media Oriented System Transport) are passed on via the telephone interface (A34/4) to the portable CTEL connected (A34/6) using discrete data lines. On request of the COMAND operating, display and control unit (A40/3), the telephone interface (A34/4) conveys the functions to be performed (e.g. dialing phone number, ON or OFF) to the portable CTEL (A34/6).
Vice versa the data (caller's voice, control data) are converted by the telephone interface (A34/4) into a corresponding MOST format and are passed on for further processing to the COMAND operating, display and control unit (A40/3). The telephone interface (A34/4) converts electrical pulses into optical pulses.
