3. Description of the product
The Advanced Telecommunication Module 2 (ATM-02) is designed and produced by peiker acustic
exclusively for OEM. The ATM-02 is assembled in the car during production. There are no other
distribution channels than assembly in the cars production line or spare part replacement within car
service.
The ATM-02 is mounted invisible to the driver in the car under the roof plane or in the trunk area. In the
roof version, the antenna is directly connected to the ATM-02. The trunk version is connected by wire to
the antennas. The only direct interface of the ATM to the driver or passenger is a dedicated push button
and LED (i.e. Mayday LED) to trigger an emergency call and signal the call status. Except this button
and the LED, there are no direct interfaces of the ATM to the driver or passengers.
The ATM-02 is connected to the internal bus and control systems of the car. The ATM-02 uses the
external antenna of the car and contains an internal backup antenna. The ATM-02 uses a factory
mounted embedded SIM card (MFF2).
3.1 Use Cases of the product
The Advanced Telecommunication Module 2 is designed as the car’s interface to the outer world in form
of data and voice communication. Typical use cases are as follows:
Exchange of diagnostic data between the vehicle and the OEM server and OEM backend.
Voice connection between vehicle and public safety answering point or vehicle and OEM call centers
Interface to networks for data exchange to support infotainment and comfort functions.
Network access service for data exchange e.g. supporting OEM-specific assist services and other
online services like weather, maps, emails for in car use.
Contains a GNSS receiver supporting GPS, GLONASS and Galileo satellite navigation systems for
position determination to be used with further services
The ATM-02 is connected to the vehicle internal bus (CAN-Bus) and network interface (OABR). It is
automatically powered up if it receives a special signal via the car bus (CAN-Bus), e.g. when the car is in
drive mode. The ATM-02 is also powered up with an out of band signaling from the cellular network, e.g.
via a receiving SMS from the OEM service center (wake up message).
The concierge calls (i.e. service calls) are performed via the multimedia audio interface of the vehicle
and the head unit (HU) provides the user interface for this type of call. The audio signal is transmitted
digitally via VoIP.
In case of an emergency OEM Assist call the ATM-02 is able to perform an autonomous mobile
originated call using the microphone and the loudspeaker connected directly to the device. The voice call
itself is fully handled by the ATM-02. This call is originated automatically e.g. in case of a crash triggered
by the Airbag ECU or manually with a service button in the control panel of the vehicle. In this case the
head unit of the car is not involved in the connection.
