Edit Table
FPGA CFG {Pass/Fail, Unmasked/Masked}
Indicates a transmit FPGA configuration failure.
DSP CFG {Pass/Fail, Unmasked/Masked}
Indicates a transmit DSP configuration failure.
SCT CLOCK PLL {Pass/Fail, Unmasked/Masked}
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
failure within the modem.
SYM CLOCK PLL {Pass/Fail, Unmasked/Masked}
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 {Pass/Fail, Unmasked/Masked}
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 {Pass/Fail, Unmasked/Masked}
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.
BUC CURRENT {Pass/Fail, Unmasked/Masked}
Indicates that the BUC current has fallen outside of the
threshold limits.
BUC VOLTAGE {Pass/Fail, Unmasked/Masked}
Indicates that the BUC voltage has fallen outside of the
threshold limits.
ETHERNET WAN {Pass/Fail, Unmasked/Masked}
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).
