Power Outage and Restoration
When a power outage begins, a timer starts counting in the NIC. The NIC will wait
until the Outage Declaration Period has lapsed to ensure that the outage is a not a
momentary interruption. If the interruption is sustained, a “last gasp” message will
be sent to the headend. As the outage continues, additional messages will be sent.
As many as 6 messages may be sent within the first 20 minutes of the outage.
Refer to the following image.

Last Gasp and Power Restoration Messages
When power is restored, a “power restored” message is sent to the headend.
