The N870 base-stations synchronised via DECT will automatically synchronize with a higher sync level. Base stations can and will skip a higher sync level if it can connect to an even higher sync level.
If you look at the picture, you can see that the base with level 3 will skip level 2, if level 1 can be seen with a good quality.
Set-up: The base with level 3 can only see the base with level 2.
If the base with level 2 is down then also the level 3 base will be down. If more bases connect to this level 2 or 3 then also these bases will not be functional.
How to add redundancy:
To place the base stations more close to each other. In the example, the base with level 3 can see level 2 and level 1.
- Base with level 3 will automatically connect to level 1 if the quality is good enough
- If Level 2 is down then level 3 will still work as it can also connect to level 1
- The calls for the base with level 2 that is down will be handled by the level 1 and 3 (Capacity has to be calculated)
When the system is using LAN synchronisation then all Bases will connect to the LAN Master which is the level 1 base (mostly), then the next chapter "Level 1 redundancy" must be used to ensure redundancy.
