^
Customer identification data
^
Vehicle identification data
Additionally, the communication module integrated into the emergency call system control unit sets up a voice communication to the CAC.
The communication module integrated into the emergency call system control unit transmits and receives the mobile phone signals or data in the
following way:
^
Discrete line
^
Frequency switchover control unit (N96), with code (389) Mobile phone preinstallation with universal interface, USA/ Canada

preinstallation with universal interface, USA/Canada, any active mobile phone connections are interrupted.
