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.
{Pass/Fail, Unmasked/Masked}
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.
{Pass/Fail, Unmasked/Masked}
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).
