•
The distance over which synchronization can take place is limited to a distance similar to a
loss of max. 25 dB. If the loss of signal is higher than 25 dB, there is no guarantee that
synchronization is stable.
•
It is recommended that a base station synchronizes with at least two other radio units and that
an alternative sync way is defined to ensure system redundancy. If the primary sync way is not
working, then the alternative sync way takes over and the synchronization chain is not broken.
•
Synchronization chains for the IP-DECT Server 6500 Solution can be made with base stations
and repeaters.
•
As you can only configure a repeater to synchronize on one radio ID, it is not possible to define
alternative sync ways for repeaters.
•
As the IP-DECT Server 6500 uses the DECT interface to synchronize on, one base station is
configured as the Sync Master.

Synchronization Chain
•
The synchronization chain must always overlap with the base station
to sync on.
•
No.0
is the Sync Master (can be numbered 0-255).
•
Other radio units are connected to the Sync Master through the
synchronization chain.
•
If one of the radio units in the synchronization chain is not working,
then the synchronization chain is broken and the system will be
unstable.
