One-Look Networking Survivability - Panasonic KX-NS1000 Manual

4.2.3 One-look Networking Survivability

Description
A One-look network can be configured so that even if the KX-NS1000 at a site fails or is otherwise disconnected
from the network, operation of the One-look network as a whole continues. The following network survivability
features are available:
Feature
Backup Master Mode
Isolated Mode
Automatic Rerouting to Secondary
PBX
UM Group Failover
If the Master unit fails, a Slave unit designated as the Backup
Master unit assumes operation as the Master unit. SIP trunks
connected through the Master unit can also be configured to
switch operation to the Backup Master unit.
® 4.2.3.1 Backup Master Mode and Isolated Mode
If the Master unit fails and either (1) there is no Backup Master
unit or (2) the Backup Master unit also fails, the Slave units
continue operating independently.
® 4.2.3.1 Backup Master Mode and Isolated Mode
If the unit to which an IP extension (e.g., IP-PT, KX-UT
extension) is connected fails, the extension can automatically
switch its connection to a secondary PBX.
® 4.2.3.2 Automatic Rerouting to Secondary PBX
When a PBX goes offline, incoming calls routed to the UM
group of the PBX can be automatically redirected to another
PBX's UM group.
