In most scenarios, the master base station (Standard or Compact) is also used as the air sync master for all the other slave base stations and that is the scenario documented in this manual. However, in scenarios where you have base stations in separate locations that are not within synchronization range of each other, it is permissible to assign separate air sync masters in each location. However, there must be absolutely no overlap (<-90dB) between the separate groups of base stations. Any overlap will cause frequent loss of synchronization.
Having separate locations, each with its own synchronization, is done through the settings on the DECT | Air Sync tab of each base station. For each location, set the same Sync Region number for all the base stations at that location, using a different number for each location. In addition, use the Sync Mode drop-down menu to configure of one of the base stations in each location as the Master base station.
Note:
In deployments in mixed systems with IP Base Stations and IP-DECT Gateways, the IP-DECT Gateways need to be physically interconnected for the purpose of radio synchronization. When configuring an IP-DECT Gateway as an air sync master, use sync region 0. All other base stations should be be configured as sync slaves. Systems with IPBS in sync regions that have only IPBS should use non-zero sync region number(s) and be configured with at least one sync master with the remaining IPBSs configured as sync slaves.
