{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.
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.
