6.2.1 Alarm Faults

6.2.1.1

Major Tx Alarms

Alarm Possible Cause
FPGA CFG Indicates a transmit FPGA hardware failure.
DSP CFG Indicates a transmit FPGA failure.
SCT Clock PLL 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 problem within
the modem.
SYM Clock PLL 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).
LB Synth PLL 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.
IF Synth PLL 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.
Ethernet WAN Indicates that the WAN Port is down.
6.2.1.2
Alarm Possible Cause
FPGA CFG Indicates a receive FPGA hardware failure.
DSP CFG Indicates a receive DSP failure.
SIGNAL LOCK Indicates that the demod is unable to lock to a signal.
FRAME LOCK Indicates that the Framing Unit is unable to find the expected framing pattern.
MULTIFRAME LOCK Indicates that the Framing Unit is unable to find the expected framing pattern.
LB SYNTH PLL 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.
IF SYNTH PLL 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.
Ethernet WAN Indicates that the WAN Port is down.
6.2.1.3
Alarm Possible Cause
TERR CLK ACT Indicates no Terrestrial Clock activity.
TERR DATA ACT Indicates no Tx Data activity.
TX TERR AIS Indicates that AIS has been detected in the Tx Data Stream.
DnI FRAME LOCK When running Drop Mode, indicates that the framing unit is unable to find the exported
terrestrial framing pattern.
DnI M-FRAME LOCK When running Drop Mode, indicates that the framing unit is unable to find the exported
terrestrial framing pattern.
TX DVB FRAME Indicates that the Tx Input Data Stream Framing does not match the user selected Tx Terr
LOCK Framing. Incorrect Tx Terr Framing selected. Incorrectly framed Tx Input Data Stream.
