This checkbox enables or disables the Redundant NMS (Controller) function,
which allows configuration of redundant NMS servers as Primary and
Secondary units. Enabling this function automatically displays the Network
Control Modem window.
The operator can also click the Setup button
on the System Setup window at any time to
display the Redundant NMS window, and
configure the following settings.
Configure as: – this refers to the NMS status
(Primary, Secondary, or No Backup).
Listen for Outbound for How Long? – this
refers to the length of time the Primary NMS
will listen for the Outbound Control Channel
during startup in order to avoid interfering
with other signals.
For a Secondary NMS, this is the period of
delay before the unit comes online or takes
over the operation of the network.
Auto restore Primary – this enables or
disables the function which will automatically
restore the Primary NMS. Auto restoration
occurs in less than 5 minutes.
Example: If the Primary NMS fails and is then backed up by the Secondary
NMS, the failed NMS will automatically be restored to Primary status as soon
as it is operational again.
