The sync-over-air solution is very reliable because all existing redundant paths are used for
synchronization. Thus, hardware tolerances have only very little influence. No RFP has a key position.
synchronization. Thus, hardware tolerances have only very little influence. No RFP has a key position.
Only unfavorable setups without redundant synchronization paths can cause problems.
Sometimes RFPs do not must be synchronized, e.g. if they are in different buildings. These RFPs can be
put into different clusters. RFPs in different clusters will not be synchronized with each other. Different
clusters start up at the same time independently.

7.2.1 INITIAL SYNCHRONIZATION PROCEDURE
To avoid synchronization problems and to speed up the synchronization on system startup, an initial
synchronization procedure is used. For every cluster the following synchronization stages are defined.
synchronization procedure is used. For every cluster the following synchronization stages are defined.
•
Synchronization stage 0
- If at least one preferred RFP was configured, the synchronization process will wait up to 30
seconds for an incoming startup message of such a preferred RFP. Receiving a message will
finishing stage 0 and the synchronization process jumps to stage 1.
finishing stage 0 and the synchronization process jumps to stage 1.
- If no message was received within the 30 seconds this stage will be terminated and the next stage
will be started.
- If no preferred RFP was configured, this stage will be ignored.
•
Synchronization stage 1
- If a preferred RFP was determined in stage 0, this one will be the synchronization source for the
next upcoming RFPs. Otherwise the first RFP which sends a startup message will be the
synchronization source for the next upcoming RFPs.
synchronization source for the next upcoming RFPs.
- In this stage, only RFPs reporting an RSSI value better than -65 dBm are permitted to perform
synchronization.
