Overall Status
Indicates Fault (RED) level or GREEN if there are no faults.
For Example
If the Dual-Band system is currently only being used to provide one service (while the
other service is disabled), the “Service Off” alarm can be masked (disabled).
In the example below, the left dialog shows the alarm response if the Service 2 alarm is
NOT masked (enabled). In that case the Overall Status will be RED indicating a fault.
If the Service 2 alarm is MASKED (disabled), then the LED for the alarm will be RED; but,
the Overall Status will be GREEN – showing NO Fault.
