Definition
Used to indicate critical alarms in the network at the local terminal.
Used to indicate major alarms in the network at the local terminal.
Used to indicate a minor alarm in the network at the local terminal.
Provides first-level alarm isolation. The REM LED turns red when an alarm
is present in one or several of the remote terminals.
Used to indicate that node timing is synchronized to an external reference.
After pressing the alarm cutoff (ACO) button, the green ACO LED
illuminates. The ACO button opens the audible closure on the backplane.
ACO state is stopped if a new alarm occurs. After the originating alarm is
extinguished, the ACO LED and audible alarm control are reset.
