CHAPTER 4 INSTALLATION
The two diagrams below show the power available on the DSI-AD2 bus in relation to the line length and
the wire diameter. The table can then be used to determine the number and type of system phones that
can be connected to the DSI-AD2 bus under the given conditions. The power available can be calculated
by measuring the loop resistance where the wire diameter is known.
Due to the different hardware versions of the radio units, the power available on the DSI-AD2 bus is not
the same in every case:
Power available case A:
• Applies to all the system phones of the MiVoice 5300 series.
• Applies to the SB-4+/SB-8 DECT radio units with hardware version "-1".

1. Assumptions:
System phones: In hands-free mode, loudspeaker on maximum volume, all LEDs lit
MiVoice 5380: Backlighting with maximum brightness
Expansion key modules: All LEDs lit
Radio units: Active call connection on all channels
2. Although no longer available, the phone is still supported.
3. The value can increase to approx. 600 mW if the power available at the DSI-AD2 bus allows it.
4. An MiVoice M535 always requires a power supply unit
5. The value applies to radio units with hardware version “-2”. The value for hardware version “-1” is 300 mW lower.
6. The value applies to each interface and to radio units with hardware version “-2”. The value per interface for radio units
with hardware version “-1” is 150 mW lower.
