5.2 Event Codes

When an alarm condition exists, the transceiver creates a code that can
be read on an HHT connected to the DIAG port. These codes can help
resolve many system difficulties. Refer to Table 11 (Page 34) for a def-
inition of the event codes.
Checking for Alarms—STAT command
To check for alarms, enter on the HHT. If no alarms exist, the mes-
STAT
sage appears at the top of the display (Figure 11).

the alarm is also provided.

Major Alarms vs. Minor Alarms

Major Alarms—report serious conditions that generally indicate a hard-
ware failure, or other abnormal condition that prevents (or seriously
hampers) further operation of the transceiver. Major alarms generally
indicate the need for factory repair. Contact GE MDS for further assis-
tance.
Minor Alarms—report conditions that, under most circumstances, do
not prevent transceiver operation. This includes out-of-tolerance condi-
tions, baud rate mismatches, and so on. The cause of these alarms should
be investigated and corrected to prevent system failure.
