- with CODE (359) TELE AID emergency call system
Usually, the telephone connections are processed via the rod antenna (A28). The left antenna amplifier module (A2/64) splits the signals of the rod
antenna (A28) into signals for the central locking (CL), the radio component of the audio source that is installed in each case, and the Universal Portable
CTEL Interface (UPCI) system. The portable CTEL antenna amplifier (A28/2) controls the signals of the rod antenna (A28). In normal mode, the signals
of the rod antenna (A28) are transmitted to the Universal Portable CTEL Interface (UPCI [UHI]) control unit (N123/1) and vice versa. In emergency
mode, the signals of the rod antenna (A28) are forwarded to the emergency call system control unit (N123/4) and vice versa.
In the event of a defective rod antenna (A28), e.g, after a rollover, the emergency call system left backup antenna (A2/54) and the emergency call system
right backup antenna (A2/55) are integrated in the rear bumper of the vehicle. The emergency call system control unit (N123/4) detects the antenna
failure and automatically actuates the emergency call system left backup antenna (A2/54) and the emergency call system right backup antenna (A2/55)
via the emergency call system antenna splitter (A2/25).
