To increase resilience of the DECT network, two base stations can be configured to operated as 'mirrored' master base stations. Only one is the active master base station at any time, however the other takes over as the master base station when required.

All the normal requirements for the master base station apply to both the mirrored base stations. That includes the air sync requirements unless air sync is assigned to another base station. See Configuring Air Sync.

Mirroring is not supported between compact and non-compact base stations. However, it is supported between a DECT Gateway and non-compact base station.
