Indicates the framing unit is unable to find the expected
terrestrial framing pattern.
{Pass/Fail, Unmasked/Masked}
Indicates the framing unit is unable to find the expected inter-
frame pattern.
Indicates that Tx input data stream framing does not match the
user selected TX TERR FRAMING.
{Pass/Fail, Unmasked/Masked}
Indicates a receive FPGA hardware failure.
{Pass/Fail, Unmasked/Masked}
Indicates a receive DSP failure.
{Pass/Fail, Unmasked/Masked}
Indicates that the demod is unable to lock to a signal.
{Pass/Fail, Unmasked/Masked}
Indicates Rx signal level has fallen below input threshold.
{Pass/Fail, Unmasked/Masked}
Indicates that the Framing Unit is unable to find the expected
framing pattern.
{Pass/Fail, Unmasked/Masked}
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 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.
