4.4.6 Alarms Menu Options and Parameters
Masking alarms may cause undesirable modem performance.
CURRENT ALARMS (menu)
TX MAJOR (menu) Status
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).
FORCED ALARM {DISABLED, ENABLED}
Allows user to disable or enable forcing of a Tx Summary Alarm.
