7.2.2 In systems where only roaming is required between buildings
In figure 5 below there is an example of an installation with three separate buildings with
no synchronization coverage between them. There is one Air Sync Master per building,
hence the installation consists of three regions synchronized separately.
Note: Regions cannot be configured for IPBLs. The IPBLs will always belong to region 0.
Figure 5. Three buildings/regions without reference sync.
7.3 Sync Slave IPBS
All IPBSs in sync slave mode sends its list of sync candidates to the Pari Master. The Pari
Masters informs the IPBS sync slave which sync candidate it shall synchronize to.
