This alarm will flash on during certain modem parameter
changes. A solid indication points toward a problem with the
incoming clock to the modem (SCTE).
{Pass/Fail, Unmasked/Masked}
Indicates that the Rx L-Band 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.
{Pass/Fail, Unmasked/Masked}
Indicates that current is either below or above the threshold
limits of the LNB, as specified by the OM20. Only active when
LNB Voltage is enabled.
{Pass/Fail, Unmasked/Masked}
Indicates that voltage is not functioning correctly when voltage
is enabled.
{Pass/Fail, Unmasked/Masked}
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).
{Pass/Fail, Unmasked/Masked}
Indicates that a Doppler Buffer underflow has occurred.
{Pass/Fail, Unmasked/Masked}
Indicates that the Doppler Buffer is about to underflow.
{Pass/Fail, Unmasked/Masked}
Indicates that the Doppler Buffer is about to overflow.
{Pass/Fail, Unmasked/Masked}
Indicates that a Doppler Buffer overflow has occurred.
{Pass/Fail, Unmasked/Masked}
Indicates that there is no Rx Data activity.
{Pass/Fail, Unmasked/Masked}
Indicates that AIS has been detected in the receive satellite data
stream.
{Pass/Fail, Unmasked/Masked}
Indicates if drop/insert data is frame locked.
{Pass/Fail, Unmasked/Masked}
Indicates if drop/insert data has multiframe lock.
{Pass/Fail, Unmasked/Masked}
