8.4.2 One-look Networking Survivability
This section provides an overview of One-look Networking Survivability.
When a fault occurs in a site containing the Master unit, the communication services in the One-look network
will stop. However, it is possible to use a Slave unit as a temporary Master unit to operate the communication
services using One-look Networking Survivability.
This feature allows users to keep using communication services via a temporary Master unit even when the
original Master is not operating.
Without this feature, when a fault occurs to the Master unit in a One-look network, all the services in all the
sites in the One-look network will stop. However, if this feature is in use, some communication services can
continue even during a network failure.
Elements in One-look Networking Survivability
When One-look Networking Survivability is used, sites in the network will be classed as one of the following.
Master site
A site in a One-look network that contains the Master unit which controls the One-look network.
Backup master site
A site in a One-look network that works as a Slave site normally. When a fault happens to the Master site,
this site can act as Master site temporarily.
Isolated site
A site that will be disconnected from other sites during a fault.
Slave site
A Slave site where the Isolated setting is disabled.
Backup Master Mode
In this mode, you specify a Backup master site. When a fault occurs to a Master site in a One-look network,
the Backup master site will act as Master site temporarily after the whole system resets. Communication
services will then be provided from the Backup master site.
