Installation & Operation Manual 33. Configuring Security Settings
33.20 Configuration Freeze and Configuration Change
Event
In a typical deployment, the Media Gateway is configured by authorized personnel as
part of initial site setup and only routine maintenance tasks such as locking or
unlocking specific trunks or performing VoP board switchover are performed later on.
For such environments, it may be desirable to “freeze” the Media Gateway
configuration to prevent its change by mistake.
When Media Gateway configuration is “frozen”, any attempt to alter it (e.g. change the
value of a configuration parameter) will fail with a corresponding error message.
Regular maintenance tasks (e.g. lock and unlock) are supported in a “frozen” state.
A “Frozen” Media Gateway includes the following indication at the top of the status
screen in the EMS:


An alternative approach to freezing Media Gateway configuration is to use a

an event, visible in the EMS Alarms Browser upon each configuration change. This
event contains a full description of the change.
