Configuring air synchronization
This section is applicable only to the IPBS System
The IPBSs use the DECT air interface to synchronize to each other. For an individual IPBS it is
not required to configure with which IPBS it needs to synchronize. It is needed to manually
select one or several IPBSs as synchronization master candidate. PARI Master assigns one of
these IPBS as an active Sync Master. The remaining candidates act as sync slaves and can be
new Sync Masters in case the active Sync Master fails. When using one sync region it is
recommended to configure at least two base stations in the middle of the building as
synchronization masters.
All IPBSs in sync slave mode sends its list over received sync candidates to the Master. The
Master informs the IPBS sync slaves which sync candidate it shall synchronize to.
Mixed System
All IPBLs are synchronization masters in region 0. Any IPBS in this region will receive its
synchronization over the air from the RFPs, which are connected to the IPBL.
Sync regions
Sync regions are used when, for example, several buildings are located in the same coverage
area and all radios are using same PARI Master but where the synchronization coverage
between buildings is not good enough for a stable synchronization.
