Under normal circumstances, the telephone connections are handled over the frequency switchover control unit (N96) and, on model 221, over the telephone and GPS roof antenna (A2/49) on the roof or, on model 216, over the telephone and GPS antenna (A2/49) in the trunk lid.
In the event of a defect of the telephone and GPS roof antenna (model 221) or of the telephone and GPS antenna (model 216), e.g. due to a rollover or poor reception, 2 backup antennas are available in the rear bumper of the vehicle, which are designated as emergency call system left backup antenna (A2/54) and emergency call system right backup antenna (A2/55).

The emergency call system control unit on model 221 detects a failure or poor reception of the telephone and GPS roof antenna and on model 216 of the telephone and GPS antenna and then automatically actuates over the emergency call system antenna splitter (A2/25) the emergency call system left backup antenna and the emergency call system right backup antenna.
