Critical alarms are failures that cause loss of service to more than four
DS1s (96 DS0 customer channels). Table A lists conditions which may
cause critical alarms.
Connect the CIT to the CIT connector on the near-end User Panel and log in to
the near-end system, if not already performed.

The rtrv-alm: command can be used to display a report of active
