This document and information contained herein is subject to the restrictions set forth on the title page .
The alarm status may be examined with the alarm command that displays the specific condition generating an
alarm, if any. The alarm command will also indicate the cause of any transient alarm that may have occurred but
is now cleared.
3.2.1 System Alarms
High Modem Temperature The temperature on the modem board exceeds the set high temperature
threshold. The factory set threshold is 50°C but may be independently
adjusted as desired.
High RF Temperature The temperature of the RF module exceeds the set high temperature
threshold. The factory set threshold is 50°C but may be independently
adjusted as desired.
High PA Temperature The temperature of the transmitter power amplifier exceeds the set high
temperature threshold. The factory set threshold is 50°C but may be
independently adjusted as desired.
3.2.2 Data Alarms
No Frame Lock The modem is not able to achieve frame lock on the incoming data. No
frame lock may indicate a poor receive signal or mismatched
configuration settings between the two ends of the link.
3.2.3 Transmit Alarms
Muted The transmitter is muted because of a configuration problem or a
transmit synthesizer problem.
Synthesizer Out of Lock The transmit synthesizer is out of lock. This may indicate an
unconfigured or misconfigured transmitter, or a hardware failure.
No Transmit Power No transmit power is detected.
Low Transmit Power The detected transmit power reading is less than 80% of its nominal
value.
3.2.4 Receive Alarms
Synthesizer Out of Lock The receive synthesizer is out of lock. This may indicate an unconfigured
or misconfigured receiver, or a hardware failure.
AGC Out of Lock The automatic gain control system is not able to achieve a suitable
receive signal level.
Low RSL The receive signal level is below the set threshold level. The RSL is not a
measured value but is inferred from the AGC system. The threshold level
may be set by the administrator and should be set to an appropriate value
depending on the expected operating conditions.
3.3 Status
Useful status information may also be displayed by various commands including rsl , stats , temp, linestat,
and ifinfo .
The rsl command continuously displays near real-time receive signal strength and may be used to “peak” the
antenna positioning when installing the system.
