{Pass/Fail, Unmasked/Masked}
Indicates a transmit FPGA configuration failure.
{Pass/Fail, Unmasked/Masked}
Indicates a transmit DSP configuration failure.
{Pass/Fail, Unmasked/Masked}
Indicates that the Tx SCT Clock PLL is not locked. This alarm
will flash on during certain modem parameter changes. A solid
indication points toward a configuration failure within the
modem.
{Pass/Fail, Unmasked/Masked}
Indicates that the Tx Symbol Clock PLL is not locked. 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 Tx 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 the Tx 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.
{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).
{DISABLED, ENABLED}
Allows user to disable or enable forcing of a Tx Summary
Alarm.
{Pass/Fail, Unmasked/Masked}
Indicates no Terrestrial Clock activity.
{Pass/Fail, Unmasked/Masked}
Indicates no Tx Data activity.
{Pass/Fail, Unmasked/Masked}
Indicates that AIS has been detected in the Tx Data Stream.
