{Pass/Fail, Unmasked/Masked}
Indicates that the Rx IF Synthesizer is not locked. This alarm
will flash on during certain modem parameter changes. A solid
indication points toward a configuration problem within the
modem.
Indicates that the interface card is faulted and will not pass data
(displays only when the Ethernet Card is installed and the
Ethernet Interface is selected).
{DISABLED, ENABLED}
Allows user to enable a forced Rx summary alarm.
Indicates that a Doppler Buffer underflow has occurred.
Indicates that the Doppler Buffer is about to underflow.
{Pass/Fail, Unmasked/Masked}
Indicates that the Doppler Buffer is about to overflow.
Indicates that a Doppler Buffer overflow has occurred.
Indicates that there is no Rx Data activity.
{Pass/Fail, Unmasked/Masked}
Indicates that AIS has been detected in the receive satellite data
stream.
Indicates if drop/insert data is frame locked.
{Pass/Fail, Unmasked/Masked}
Indicates if drop/insert data has multiframe lock.
{Pass/Fail, Unmasked/Masked}
Indicates if the Circular Redundancy Check is passing in PCM-
30C and PCM-31C Modes.
{Pass/Fail, Unmasked/Masked}
The interface is not deleting the expected signaling information.
{Pass/Fail, Unmasked/Masked}
Indicates that the Framing Unit is unable to find the expected
framing pattern.
{Pass/Fail, Unmasked/Masked}
Indicates that the Reed-Solomon Decoder is not locked.
