General 

Normally the mobile phone signals or data for the following vehicle-related services are transmitted and received by the communication module integrated into the emergency call system control unit (N123/4) via the TELE AID antenna:

• Authorization (provisioning)
• Emergency call (E-Call) manual or automatic, including police emergency call number "911"
• MB-Info call
• Breakdown assistance (Roadside Assistance)
• Vehicle tracking
• Vehicle remote door unlock

If the TELE AID antenna is defective, the communication module integrated in the emergency call system control module transmits and receives, via the TELE AID backup antenna (A2/50).

Function sequence 

The emergency call system control unit monitors the TELE AID antenna over a discrete line.

The emergency call system control unit recognizes a malfunction in the TELE AID antenna (e.g. defective due to rollover) or poor reception and then automatically transmits or receives the mobile phone signals or data for the specific vehicle-related service over a discrete line and the TELE AID backup antenna.
