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.
