All the licences are offered in separate licence packages. Depending on the sales
channels the packages may differ from the licences in Tab. 28. The systems ship out
unlicensed. Back-licensing is not provided for.However, resetting to the factory setting
is possible.
OIP licences
OIP licences are managed by OIP itself. A detailed description of the OIP licences can
be found in the System Manual Mitel Open Interfaces Platform.

Power supply capacity
The maximum number of terminals connected to the system can be limited by the sup-
ply power available for terminals. It is also important to take note of the maximum load
per terminal interface.
3. 4. 10. 1
Supply power available for terminals
The 40/48 VDC power supply required for the connected terminals is rated for the
power requirements of a typical system configuration.

The number of permissible terminals per system depends on the power requirements
of the individual terminals. To check the power requirements refer to Tab. 30 for details
of the average power requirements of the terminals.
The total power requirements of all connected terminals must not exceed the available
power output of the power supply.
Note
The actually required power supply depends strongly on the call traffic, the wire diameter and
the line length to the connected terminals. The values in the following table are average values
under the following assumption:
– Phones traffic volume: Call Connection 38%, Ringing 2%
– SB-4+ radio unit: Active call connection on 2 channels
– SB-8 radio unit: Active call connection on 4 channels
– Background lighting MiVoice 5380: 30% active
4) If Virtual Appliance is used as Master, the VoIP channels of the master node are made available without a li-
cence from the integrated Mitel Media Server. However, for the satellites' VoIP channels, the licences must
be purchased.
5) If VoIP mode is set to G.711, two G.711 VoIP channels per system can be used without a licence.
6) For Virtual Appliance this licence is only relevant to the QSIG networking of an AIN satellite.
