Universal Portable CTEL Interface (UPCI), function - GF82.70-P-0004S: Notes

MODELS 215, 220 as of 1.6.04 with CODE (388) "Portable CTEL" UPCI telephone system 

Function requirements:

• Voltage supply OK.
• MOST ring active.
• Portable CTEL (A34/6) inserted in the UPCI Portable CTEL receiver (Universal Portable CTEL Interface) (A34/15).
• Enabled SIM card inserted into the portable CTEL (A34/6).
• Correct entry of PIN and successful log-in into the particular network of the service provider.

With the Universal Portable CTEL Interface system (UPCI), all phone calls with the portable CTEL (A34/6) take place exclusively via the hands-free system.

Calling in "private mode" is only possible with the rear telephone handset (A34/8) (model 220 only).

The universal Portable CTEL Interface (UPCI) control unit (N123/1) makes it possible to alternatively operate different portable CTELs (A34/6), e.g., Nokia, Siemens, and Motorola, in the vehicle.

To do this, the particular UHI portable CTEL holder (Universal Portable CTEL Interface) (A34/15) has to be replaced.

Besides, it is also possible to operate Bluetooth-capable devices (e.g., rear telephone handset (A34/8)) (not with USA version).

The Universal portable CTEL Interface system (UPCI) consists of the following components:

• Universal Portable CTEL Interface (UPCI) control unit (N123/1)
• UHI portable CTEL holder (Universal Portable CTEL Interface) (A34/15)
• Telephone antenna (A2/22 (model 215), A2/49a1 (model 220))
• Telephone/portable CTEL/STH radio remote control antenna splitter (A2/53)
• CTEL compensator (A28/3)
• Portable CTEL (A34/6)
• Handsfree microphone (B25)
• Bluetooth antenna (A2/91) (not with USA version)
• COMAND operating, display and control unit (A40/3) with code (527) COMAND APS (with navigation).

The particular Portable CTEL (A34/6) is connected to the Media Oriented System Transport (MOST) of the vehicle via the UHI portable CTEL holder (Universal Portable CTEL Interface) (A34/15) and the Universal Portable CTEL Interface (UPCI) control unit (N123/1).

The Universal Portable CTEL Interface system (UPCI) includes the following functions:

• Establishing the telephone connections in hands-free mode.
• Establishing the telephone connections in "private mode" (Bluetooth) (not with USA version).

  (Only  possible with the rear telephone handset (A34/8)).

• WAP (Wireless Application Protocol) (is shown via the portable CTEL (A34/6) only in the display of the COMAND operating, display and control unit (A40/3)).
• Displaying telephone numbers and call recognition.
• Showing stored telephone numbers from the portable CTEL (A34/6) in the multifunction display (A1p13) of the instrument cluster (A1) (selection of the menu item "TEL" using the system selection button (S110s3) and browsing (telephone book function) with the scroll forward/back button (S110s1)).

The Universal portable CTEL Interface system (UPCI) is activated using the on/off button of the portable CTEL (A34/6).

There is also the option to activate the system automatically through a wake-up pulse via the MOST ring. It can be started via status "circuit 15 ON", or with Code (527) COMAND APS (with navigation) via the COMAND operating, display and control unit (A40/3).

The Universal portable CTEL Interface system (UPCI) is deactivated using the on/off button of the portable CTEL (A34/6) or automatically based on the run-on time set at the portable CTEL (A34/6).

The voice input takes place via the hands-free system microphone (B25). If a voice control system control unit (A35/11) is installed with code (813) voice control system (VCS), the voice input is transmitted through this system and the MOST ring to the universal Portable CTEL Interface (UPCI [UHI]) control unit (N123/1).

The voice output takes place via the speaker system. To ensure the greatest possible stability of user voice input of the user via the hands-free system microphone (B25), the volume of an active audio source (e.g. the CD player with changer (in trunk) (A2/6)) is automatically muted during a telephone call. The volume of the speaker system can be adjusted individually by the user. This is possible with the aid of the + and a buttons integrated in the multifunction steering wheel (MFL), for the adjustment of specific functions and the volume control (S111s1), or via the portable CTEL (A34/6).

Additional functions can be carried out with the aid of additional buttons at the multifunction steering wheel (MFL):

• Scroll forward/back pushbutton (S110s1)
• System selection button (S110s3)
• Accept/terminate phone call button (S111s3)

This is shown through a number of displays that inform the user of the operating condition (e.g. "ENTER PIN") of the portable CTEL (A34/6) in the displays of the following components:

• Portable CTEL (A34/6)
• Multifunction display (A1p13) in the instrument cluster (A1)
• with code (527) COMAND APS (with navigation) in the display of the COMAND operating, display and control unit (A40/3)

The Universal Portable CTEL Interface system (UPCI) is compatible with the D-net and the E-net. This is made possible by the installation of the E-net compensator (A28/3), which compensates the damping that occurs through the higher transmission frequency of the E-net.
