- If an RFP has done its synchronization, this RFP will be also a synchronization source for other
upcoming RFPs.
- The initial timeout for this stage is 30 seconds. Whenever an RFP has finished its synchronization
in this stage a new stage timeout value will be calculated.
- If no RFP comes up within the timeout time or if all the upcoming RFPs do not fit the RSSI
threshold, this stage will be terminated and the next stage will be started.
•
Synchronization stage 2
- The behavior of this stage is identical to stage 1, but an RSSI threshold value of -70 dBm is
significant.
•
Synchronization stage 3
- The behavior of this stage is identical to stage 1, but an RSSI threshold value of -75 dBm is
significant.
•
Synchronization finished
- No more RSSI threshold value is significant. All RFPs that failed the stage conditions above are
now permitted to perform synchronization.
The last level “synchronization finished” will be achieved either all registered RFPs of this cluster are
synchronized or the timer of stage 3 expires.
synchronized or the timer of stage 3 expires.
7.2.2 CHECKING THE SYNCHRONIZATION OF A NETWORK
For every cluster a periodically check of the synchronization of the network is done. If the network is split
into at least two subnets, all the RFPs of the lesser subnet(s) will be resynchronized. While doing initial
synchronization procedure this check is deactivated. You can check the RFP synchronization using the
Sync view menu of the OM Management Portal (OMP), see section 6.7.6.

7.3 RFP CHANNEL CAPACITY
The RFP has 12 available time slots on air; eight can have associated DSP/media resources for media
streams. All DECT time slots are used for control signaling, software download over air, messaging and
bearer handover independent of associated DSP/media resources.
streams. All DECT time slots are used for control signaling, software download over air, messaging and
bearer handover independent of associated DSP/media resources.
If all eight media stream channels are used, the RFP announces a “busy bit”. In that case, the DECT
phones determine whether another RFP has an appropriate signal strength. If so, the DECT phone will
handover to that RFP. Once the handover has been completed, the RFP will then lower its “busy bit”.

Whenever the busy state is announced a log entry is made to the system logs. If the announcement of
busy raises in a specific area, a further RFP should be installed to double the number of media streams
available for calls.

Notes on Hi-Q connections
Each Hi-Q connection uses, compared to conventional narrowband, the double capacity on the DECT air
interface. Due to this fact, four Hi-Q connections (instead of eight) can be established via one RFP.

It is not possible to have DECT XQ audio combined with Hi-Q audio within the same connection.
