Block diagram COMAND telephone system, illustrated with the following equipment:
- D network cellular telephone (D2B) (code 317)
- Sound system (code 810)
- Voice control system (VCS) (code 813b)

The marked elements are the components which are essentially used for telephone operation.

The telephone system can be operated as follows:
- directly with the COMAND operating, display and control module (A40/3) or
- with the multifunction steering wheel in combination with the multifunction display in the instrument cluster (A1) or
- by voice control (code 813b)

When a telephone call is in progress, the audio source is automatically muted. Different versions of telephones are available (cellular, permanently installed, version in combination with TELE AID). The cellular telephone version (code 317) is described in detail below.

The radio frequency telephone signals are transferred and received by the telephone components for the CTEL and GPS roof antenna (A2/49). The reception field strength is indicated in 5 stages on the A40/3 when the telephone is ready for operation. All control and audio signals (e.g. audio signals for activated hands-free system) are transferred via the digital data bus (D2B). The CTEL (A34/6) therefore requires an interface to the D2B - the D2B interface for cellular telephone (A59/1).

The COMAND operating, display and control module (A40/3) provides the following telephone functions:
- Automatic disabling feature for telephone card when Personal Identifier Number (PIN) is entered incorrectly three times.
- A 112 emergency call can be completed even without Personal Identifier Number (PIN) and without telephone card.
- Direct entry of the telephone number with the control knob or number pad, display of name of party called (if number entered is known).
- Abbreviated dialing: The first 10 memory locations can be selected by pressing one key only, selection of all other memory locations by entering three digit memory location number.
- Sorting possibility for memory location according to:
-> memory location number or
-> names (alphanumeric) or
-> last 10 numbers dialed.
- Display of telephone number for incoming call (when number is transmitted with RF signal), display of name of calling party (if COMAND knows number).
