AMASK [0000 0000–FFFF FFFF]
Table 8 and Table 9 listed the major and minor alarm classifications. It is
possible to reassign alarm outputs (illustrated in Figure 14 on page 19) to a
different category, and change which alarm events trigger an automatic
switchover in redundant master stations. However, this should be done rarely,
if ever.
The command and
AMASK
major and minor alarm events, respectively, changing the alarm output relay
status and switchover conditions. These commands can be used to tailor a
radio's alarm response. For example, a major alarm at a redundant master
station causes switch-over to the other transceiver board. By reconfiguring a
minor alarm as a major alarm, switch-over can be forced at the occurrence of
a (formerly) minor alarm condition.
Reclassifying alarms does not disable alarm notification. The front panel
LED illuminate, the alarm event is logged, and the
ALARM
commands show the alarm status.
Entering the command alone displays the current setting of major
AMASK
alarm events in hexadecimal format. Entering the
by an eight-digit hexadecimal number reassigns each of the 32 possible alarm
events as enabled or disabled, with respect to major alarm output relay status
and switchover criteria.
The hex value for the mask corresponds to the hex value for the
command (see the
ALARM
identifies the associated alarm event as a major alarm. Each bit that is a '0'
means that the alarm condition will not cause an alarm output relay to be
asserted, and will not cause a radio to switch over.
For more information on configuring the alarm response, contact the GE MDS
Technical Services group and request the AMASK application bulletin.

Description
The 10 volt power regulator output is out of tolerance. If
the voltage is too far out of tolerance, the radio may not
work.
The dc input supply voltage is out of tolerance. If the
supply voltage is too far out of tolerance, the radio may not
work.
LNA current fault. (LNA current is out of range.)
Total board current fault. (Total board current is out of
range.)
The radio's internal temperature is approaching an
out-of-tolerance condition. If the temperature drifts outside
of the recommended operating range, the radio may not
work.
