TM110 – Rev. 1.3
Possible Cause
Indicates a receive FPGA hardware failure.
Indicates a receive DSP failure.
Indicates that the demod is unable to lock to a signal.
Indicates that the Framing Unit is unable to find the
expected framing pattern.
Indicates that the Framing Unit is unable to find the
expected framing pattern.
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.
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 WAN Port is down.
Possible Cause
Indicates no Terrestrial Clock activity.
Indicates no Tx Data activity.
Indicates that AIS has been detected in the Tx Data Stream.
When running Drop Mode, indicates that the framing unit is
unable to find the exported terrestrial framing pattern.
When running Drop Mode, indicates that the framing unit is
unable to find the exported terrestrial framing pattern.
Indicates that the Tx Input Data Stream Framing does not
match the user selected Tx Terr Framing. Incorrect Tx Terr
Framing selected. Incorrectly framed Tx Input Data Stream.
