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.
