Major Alarms vs. Minor Alarms
Major Alarms—report serious conditions that generally indicate a
hardware failure, or other abnormal condition that will prevent (or
seriously hamper) further operation of the transceiver. Major alarms
generally indicate the need for factory repair. Contact your factory
representative for assistance.
Minor Alarms—report conditions that, under most circumstances will
not prevent transceiver operation. This includes out-of-tolerance con-
ditions, baud rate mismatches, etc. The cause of these alarms should
be investigated and corrected to prevent system failure.
Event Code Definitions
Table 4 contains a listing of event codes that may be reported by the
transceiver. The codes shown are a subset of a larger pool of codes
used for various GE MDS products. For this reason, the table does not
show a sequential listing of all code numbers. Only the codes appli-
cable to this product are shown.
