Description
A transmit FPGA hardware failure exists.
A transmit FPGA failure exists.
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.
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).
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.
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.
Allows the user to disable or enable forcing of the Tx summary
alarm.
The WAN Port is not operating.
This alarm is acgtive during the time that the TRANSEC card is
booting
Description
