FAQ Nx70 - Redundancy - DECT Manager (DM) (Hidden)

Introduction

From software 2.47 DM redundancy for testing is implemented.

DECT manager redundancy needs working integrator:
- Implementing backup DM without planning redundancy for integrator has limited value.
- For DM redundancy it is recommended to plan redundancy for VI by the machine virtualization.
We advise to disable the DECT Base on the Master DECT manager:
- The backup DM and the DM redundancy feature can only provide redundancy for the DM role, but not for the local base functions!
- Therefore you should not plan with the local base, if you are planing for DM redundancy.
Add Back-up DECT manager, today via provisioning only
No fallback to Master DM. Master will become back-up DM
Back-up DM does not consume an additional DM license
Failover when:
- Backup DM recognizes, that significant majority of base stations are disconnected from master DM
- Backup DM recognizes, that significant majority of base stations are connectable to backup DM
  _{significant >= ( 60% + 1 of active base stations}
- this situation continuosly lasts for more than 7 minutes this way preventing failover under regular software update duration (6 minutes).
