MN-DMD2050E Revision 2 6–3
6.3 Alarms
6.3.1 Major Transmit Alarms
Alarm Description Status
FPGA CFG A transmit FPGA hardware failure exists. {Pass/Fail,
Unmasked/Masked}
DSP CFG A transmit FPGA failure exists. {Pass/Fail,
Unmasked/Masked}
SCT Clock PLL The Tx SCT Clock PLL is not locked. This alarm flashes on
during certain parameter changes. If the alarm is on constantly,
there is a configuration problem within the modem. {Pass/Fail,
Unmasked/Masked}
SYM Clock PLL The Tx Symbol Clock PLL is not locked. This alarm flashes on
during certain parameter changes. If the alarm is on constantly,
there is a configuration problem with the incoming clock to the
modem (SCTE). {Pass/Fail,
Unmasked/Masked}
LB Synth PLL The Tx L-Band Synthesizer is not locked. This alarm flashes on
during certain parameter changes. If the alarm is on constantly,
there is a configuration problem within the modem. {Pass/Fail,
Unmasked/Masked}
IF Synth PLL The Tx IF Synthesizer is not locked. This alarm flashes on
during certain parameter changes. If the alarm is on constantly,
there is a configuration problem within the modem. {Pass/Fail,
Unmasked/Masked}
Forced Alarm Allows the user to disable or enable forcing of the Tx summary
alarm. {DISABLED,
ENABLED}
Ethernet WAN The WAN Port is not operating. {Pass/Fail,
Unmasked/Masked}
TRANSEC NOT RDY This alarm is acgtive during the time that the TRANSEC card is
booting {Pass/Fail,
Unmasked/Masked}
6.3.2 Major Rx Alarms
Alarm Description Status
FPGA CFG A receive FPGA hardware failure exists. {Pass/Fail,
Unmasked/Masked}
DSP CFG A receive DSP failure exists. {Pass/Fail,
Unmasked/Masked}
SIGNAL LOCK The demod cannot lock to a signal. {Pass/Fail,
Unmasked/Masked}
