3.6 USER LICENCE 
The OMM must be enabled with a license key (user licence), which depends on the MAC 
address of some RFPs in the DECT system The license key is entered and managed via the 
OMM web interface 
There are several types of licences: 
♦ 
♦ 
Licence for 1 or 2 RFPs 
Licence for more than 2 RFPs 
As mentioned above, the licence depends on the MAC addresses of the DECT system RFPs 
(RFP licence). 
Each RFP is associated with a licence regardless of its location. 
The number of RFP MAC addresses encoded in the license depends on the size of the DECT 
installation. 
 
System size  
(Number of RFPs) 
Number of RFP MAC addresses 
encoded in the licence (RFP licence) 
1 1 
2 
2 (1, if a second RFP has been added to a single-RFP 
system) 
More than 2  3 
 
In addition to the MAC addresses the PARK (Portable Access Rights Key), which identifies the 
DECT installation, is also part of the licence. 
Since a DECT system can only be operated with a valid PARK, a DECT installation without a 
license will be inactive. 
 
Depending on the size of the IP DECT system, it will still work if some RFP licences are out of 
service. 
 
System size  
(Number of RFPs) 
Number of RFP licences Minimum number of  
RFP licences available 
1 1  1 
2 2  1 
More than 2  3 2 
 
If the minimum number of RFP licences cannot be reached by the OMM, or if the number of 
managed RFPs is above the number of licences, the DECT system will block voice 
transmissions.
