In the event of a service call (MB-Info or roadside assistance call), active telephone connections are interrupted. The emergency call system control unit (N123/4) sends a Short Message Service (SMS) message to the nearest Service Center and always establishes a telephone connection to the Service Center at the same time.

The telephone connections are usually handled via the rod antenna (A28). The left antenna amplifier module (A2/64) splits up the signals from the rod antenna (A28) into the signals for the central locking (CL), the radio component of the audio unit that is installed and the Universal Portable CTEL Interface (UPCI) system. The portable CTEL antenna amplifier (A28/2) controls the signals from the rod antenna (A28). During normal operation the signals from the rod antenna (A28) are relayed to the Universal Portable CTEL Interface (UPCI [UHI]) control unit (N123/1) and vice-versa. During emergency operation the signals from the rod antenna (A28) are relayed to the emergency call system control unit (N123/4) and vice-versa.

If the rod antenna (A28) is defective because the vehicle has rolled over, for example, 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).
