SYSTEM MESSAGES
This message displays when a C-level program abnormal state is detected as permanent. When the Port
Microprocessor (PM) on an LC/TRK card detects the abnormal state, the PM places the card into make-busy
status. If the failure occurs more than 15 times an hour, the system judges the failure as permanent, and issues
the [3-B] system message.

This message displays when C-level program is detected as abnormal by the Port Microprocessor (PM)
mounted on an LC/TRK card. If the failure occurs less than 15 times/hour, and a B-monitor/Initial restart
executes as the result, the failure is judged as temporary and this message is created.

SYSTEM MESSAGES
At the periodic interval, the CPU sends diagnosis data to the Port Microprocessor (PM) on LC/TRK cards in
order to monitor the PM. If the CPU cannot receive the return data within a predetermined period of time, the
system displays this data. When the failure is detected more than 15 times per hour, the failure is judged as
permanent.

This message displays when over current of the operating power (DC-48V) is supplied from the ATI/ELC
circuit card to the Attendant Console/Dterm. When this fault occurs, the related circuit card is placed into make-
busy state and stops supplying power.
