GF82.70-P-2007CWJ Telephone Switch-on/Switch-Off Characteristics, Function

GF82.70-P-2007CWJ Telephone Switch-on/switch-off Characteristics, Function
- with CODE (498) Japan version

Function requirements
^ Status "circuit 30 ON" or "circuit 15R ON"
^ Mobile phone system operating error-free
^ One mobile telephone network is available in sufficient strength and quality
^ Mobile phone electrical connector (X39/37) connected to communication control unit (N123/6)
^ Compatible mobile phone connected to pre-installed connector or Bluetooth-compatible mobile phone in the vehicle and logged on to the COMAND controller unit (A40/3)

The connector is used to connect the various mobile phones to the communication control unit.

A Bluetooth-compatible mobile phone can only be operated in the vehicle if a mobile phone is not connected to the connector.

The function is described with a mobile phone attached to the connector. Any differences with a mobile phone not attached to the connector or one operated using Bluetooth are described as information points in each respective component function.

General
For status "circuit 30 ON" the COMAND controller unit has to be manually switched on so that the mobile phone is switched on via a wake-up pulse from the COMAND controller unit.
For status "circuit 15R ON" the COMAND controller unit is automatically switched on; this in turn also automatically switches on the mobile phone by means of a wake-up pulse from the COMAND controller unit.
The mobile phone can be switched off at status "circuit 30 ON" by manually switching off the COMAND controller unit, which sends a corresponding signal to the mobile phone, or following expiration of the run-on time as configured on the mobile phone.
The mobile phone is switched off automatically at status "circuit 15R OFF" by the COMAND controller unit, which sends a corresponding signal to the mobile phone, or following expiration of the run-on time as configured on the mobile phone.
A mobile phone not attached to the connector and operated over Bluetooth can only be switched on or off using the buttons on the mobile phone.

The switch On/Off characteristics function consists of the following component functions:
^ Switch on function sequence
^ Switch off function sequence

Switch on function sequence
The switch on signal (wake-up pulse) is forwarded by the COMAND controller unit as follows to the mobile phone:
^ Discrete line
^ Communication control unit
^ Discrete line
^ Plug connection

The mobile phone is then switched on and supplied with power. If configured on the mobile phone, the lock-code query is presented after switching on the mobile phone.

The lock-code query is forwarded from the COMAND controller unit over a low voltage differential signaling (LVDS) line to the Audio/ COMAND display (A40/8) and over the interior CAN to the display in the instrument cluster (A1).
Depending on the request concerned the lock-code must be entered by one of the following options:
^ Buttons on the mobile phone
^ Phone buttons on the COMAND controller unit

The control signals of the mobile phone buttons are forwarded in the following way to the COMAND controller unit:
^ Plug connection
^ Discrete line
^ Communication control unit
^ Discrete line

The control signals from the COMAND controller unit telephone buttons are processed internally.
After entering the lock-code, the reception status is received by the COMAND controller unit in the following way over the multifunction antenna (A28/11):
^ Discrete line
^ Plug connection
^ Discrete line
^ Communication control unit
^ Discrete line

The reception status is shown when the COMAND controller unit sends it over an LVDS line to the Audio/COMAND display.

A mobile phone not connected to the connector and operated over Bluetooth processes the switch-on signal internally in the mobile phone. The display of the lock-code query, if configured on the mobile phone, is only shown on the mobile phone display. The lock-code can only be entered using the mobile phone buttons. The reception status is received by the mobile phone's antenna. The display of the lock-code and the reception status as well as the signals of the mobile phone buttons are processed internally in the mobile phone.

Switch off function sequence
The switch off signal (corresponding signal) is forwarded by the COMAND controller unit to the mobile phone in the following way:
^ Discrete line
^ Communication control unit
^ Discrete line
^ Plug connection

The mobile phone is then switched off and power supply interrupted. Expiration of the run-on time configured in the mobile phone takes place internally in the mobile phone.

A mobile phone not connected to the connector and operated over Bluetooth processes the switch-off signal internally in the mobile phone. If the rechargeable battery of the mobile phone is empty, the mobile phone is also switched off. This process also runs internally in the mobile phone.
