Remote power fail indication indicates to one side that the other side
has had a power failure. The failed site sends a final trap indication
about the power loss just before powering off.
A Dying-Gasp circuit identifies the power failure at a minimum interval
of 20 milliseconds before the IDU crash, during that interval a message
notifying the power failure is sent to the remote end.
Alarm output number 4 indicates link loss due to power failure at the
remote end.
