MODEL 202 with CODE (316) MB GSM cellular telephone (D2B)

On / off characteristics of D2B telephone (fixed installation) The characteristic of the D2B telephone in the D2B ring is solely dependent on the state of terminal 15 (ignition ON/OFF). Information regarding the state of terminal 15 is sent to the D2B interface fixed installation (A59) from the Head Unit (COMAND/radio) via the D2B ring. The D2B interface fixed installation (A59) is not electrically connected to terminal 15 and switches the CTEL transmitter/receiver (A35) on or off when commanded by the Head Unit, via the D2B ring or an external wake-up circuit. After the ignition is switched off the D2B interface fixed installation (A59) and therefore the telephone remains switched on for an overshoot period of t=10 min. before being switched off. It is not possible to reprogram the overshoot period. System performance The D2B interface fixed installation (A59) has three operating states. - Powerdown mode The D2B interface fixed installation (A59) is switched off with the exception of the external wake-up circuit.

- Idle or overshoot time mode The remaining components in the D2B ring are switched off, only the D2B interface fixed installation (A59) remains active for t=10 min after the D2B ring has been switched off (ignition OFF). Each further key operation, during the overshoot period, extends the overshoot period by t=60 min. - Active mode Both the D2B interface fixed installation (A59) and the other components in the D2B ring remain active and available to the user. Switch-on operation 1. Current state: ignition ON, D2B interface fixed installation (A59) is in inactive mode (powerdown mode), the telephone system is not operational. The D2B interface fixed installation (A59) is activated (active mode) when: - The telephone is switched on by the handset - a telephone that is in the receptacle is switched on and makes a call (incoming/outgoing) - a wake-up signal of another D2B ring subscriber is recognized via the external wake-up circuit

2. Current state: ignition OFF, the D2B interface fixed installation (A59) is in the overshoot phase (idle mode) and the D2B ring is in inactive mode (switched off) The D2B interface fixed installation (A59) is activated (active mode) when: - a telephone that is in the receptacle is switched on and makes a call (incoming/outgoing) - a wake-up signal of another D2B ring subscriber is recognized via the external wake-up circuit Switching-off process The D2B interface fixed installation (A59) is in the overshoot phase (idle mode) and the D2B ring is switched off. The following cases are possible depending on the status of terminal 15:

- Terminal 15 ON After expiry of the overshoot period of t=10 min (no further telephone key operations during the overshoot period) the D2B interface fixed installation (A59) switches off (powerdown mode). The status of the telephone is not altered here, in other words, a switched on telephone remains so and is not switched of by the D2B interface fixed installation (A59) . - Terminal 15 OFF After expiry of the overshoot period of t=10 min (no further telephone key operations during the overshoot period) the D2B interface fixed installation (A59) switches off (powerdown mode). The status of the telephone is altered here, in other words, a switched on telephone is switched off by the D2B interface fixed installation (A59). When the D2B ring is deactivated the D2B interface fixed installation (A59) is switched off if the telephone is not switched on.

MODEL 202 with CODE (317) GSM portable cellular telephone (D2B)

On / off characteristics of D2B telephone (portable CTEL) The characteristic of the D2B telephone in the D2B ring is solely dependent on the state of terminal 15 (ignition ON/OFF). Information regarding the state of terminal 15 is sent to the D2B interface portable CTEL (A59/1) from the Head Unit (COMAND/radio) via the D2B ring. The D2B interface portable CTEL (A59/1) is not electrically connected to terminal 15 and switches the portable CTEL on or off when commanded by the Head Unit, via the D2B ring or an external wake-up circuit. After the ignition is switched off the D2B interface portable CTEL (A59/1) and therefore the telephone remain switched on for an overshoot period of t=10 min. before being switched off. It is not possible to program another overshoot period because the interface's overshoot period is preprogrammed and unalterable. Neither is it possible to influence the on/off characteristic of the D2B telephone by programming the portable CTEL. System performance The portable CTEL D2B interface (A59/1) has three operating states. - Powerdown mode The interface is shut down with the exception of the external wake up circuit.

- Idle or overshoot time mode The remaining components in the D2B ring are switched off, only the interface remains active for t=10 min after switching off the D2B ring (ignition OFF). Each further key operation, during the overshoot period, extends the overshoot period by t=60 min. - Active mode Both the interface and the remaining components in the D2B ring are active and available to the user. Switch-on operation 1. Current state: ignition ON, portable CTEL D2B interface (A59/1) is in inactive mode (powerdown mode), the telephone system is not operational. The portable CTEL D2B interface (A59/1) is activated (active mode) when: - a portable CTEL, in switched-on state, is inserted into the portable CTEL's receptacle - a portable CTEL in the receptacle is switched on - a portable CTEL that is in the receptacle and switched on makes a call (incoming/outgoing) - a wake-up signal of another D2B ring subscriber is recognized via the external wake-up circuit

2. Current state: ignition OFF, the portable CTEL D2B interface (A59/1) is in the overshoot phase (idle mode) and the D2B ring is in inactive mode (switched off) The portable CTEL D2B interface (A59/1) is activated (active mode) when: - a portable CTEL that is in the receptacle and switched on makes a call (incoming/outgoing) - a wake-up signal of another D2B ring subscriber is recognized via the external wake-up circuit Switching-off process The portable CTEL D2B interface (A59/1) is in the overshoot phase (idle mode) and the D2B ring is switched off. The interface remains switched off for as long as there is no portable CTEL in the receptacle or when one is in the receptacle but not switched on.

The following cases are possible depending on the status of terminal 15: - Terminal 15 ON After expiry of the overshoot period of t=10 min (no further key operations on the portable CTEL during the overshoot period) the interface is switched off (powerdown mode). This does not alter the state of the portable CTEL in the receptacle, in other words, a portable CTEL in the receptacle and switched on remains switched on and is not switched off by the interface. - Terminal 15 OFF After expiry of the overshoot period of t=10 min (no further key operations on the portable CTEL during the overshoot period) the interface is switched off (powerdown mode). This alters the state of the portable CTEL in the receptacle, in other words, a portable CTEL in the receptacle is switched off by the interface. When the D2B ring is deactivated the portable CTEL D2B interface (A59/1) is switched off if a portable CTEL is not in the receptacle or if a portable CTEL is in the receptacle but not switched on. The interface remains active for the duration of the overshoot period, when a portable CTEL is inserted into the receptacle and switched on.
