Update License
Updates from release 2.1 to 3.0 need an update license. A free update license can be
received up to one year after the initial SIP–DECT 2.1 license activation. After this time an
update license is required.
6.1.1 Grace Period
The OMM identifies medium and large systems using the unique PARK as well as the MAC
addresses of up to three RFPs (called validation RFPs here).
The number of three RFPs guarantees a redundancy when a hardware or network error
occurs. On the other hand, an odd number does not allow system duplication with splitting
the system into two separate parts.
When the 1 st validation RFP is disconnected the OMM generates just a warning. This
warning will be displayed on the Status page of the OM Web service, see also chapter 7.3.

But when the 2 nd validation RFP is disconnected, the OMM considers a license violation. In
this case a grace period of up to 72 hours starts to decrement. When the timer expires, the
OMM restricts all licensed features.
When the validation RFPs are reconnected to the OMM, the grace period is incremented
until it reaches its maximum of 72 hours. In other words the grace period must be recharged
the same time as the violation last to gain the full redundancy time.
