MODEL 230 up to 30.6.04 with CODE (349) E-Call emergency call system with CODE (494) USA version 

After an emergency call has been triggered (automatically or manually) the E-call control unit (A35/8) generates an alarm call telegram which is ultimately sent via the cellular telephone system to the E-Call Center.

In the case of an emergency call the E-call control unit (A35/8) takes over the sole control of the phone system in order to ensure the following:

• If the telephone interface (A34/4) was switched off prior to the emergency alarm being triggered, it has to be activated,
• That any existing telephone call is interrupted (ITGS too),
• That operation of the telephone interface (A34/4) with the aid of the telephone handset (A34) is no longer possible.

The radio connection is setup over the telephone transmitter/receiver, D2B (A35/13) with the aid of the telephone antenna (A2/22).

If the telephone antenna (A2/22) is no longer functioning as the result of an accident, the E-call control unit (A35/8) switches automatically over to the emergency call backup antenna (A2/50). The E-CALL center receives the emergency call. For this purpose it is equipped with a graphic-capable workstation with road data base. There, among others, the location of the vehicle is determined from the information of the emergency call telegram. The E-call center relays the decoded emergency call telegram to the responsible rescue center (police, fire department, etc.).

The emergency call system must be authorized to transmit an emergency call telegram.

This service has not been available in Japan since 31.12.2003.
