Bit 0 = Backup 1 assigned to this modulator
Bit 1 = Backup 2 assigned to this modulator
(0 = not assigned, 1 = assigned)
Bit 0 = Backup 1 assigned to this demodulator
Bit 1 = Backup 2 assigned to this demodulator
(0 = not assigned, 1 = assigned)
Channel 0 Modulator backup priority (0 - 9)
Channel 0 Demodulator backup priority (0 - 9)
0 = Switch Mod and Demod separately
1 = Switch Mod and Demod together
*Note: These 10 bytes repeat for channels 1 - 9 (uses 90
additional bytes). The Backup Delay applies only to
channels 1 - 9 (the four channel 0 bytes are ignored). If
channel 9 is configured as backup 2, then the four channel
9 Backup Delay bytes are ignored.
Bit 0 = RAM/ROM fault
Bit 1 = No Backup for Faulted Prime
Bit 2 = Error During Backup
(0 = mask, 1 = allow)
Bit 0 = Power Supply #1 Present
Bit 1 = Power Supply #1 Voltage
Bit 2 = Power Supply #2 Present
Bit 3 = Power Supply #2 Voltage
Bit 4 = Communications Error
Bit 5 = Faulted Prime Modem
Bit 6 = Faulted Backup Modem
Bit 7 = Modem Configuration Change
(0 = mask, 1 = allow)
Bit 0 = CDM Error
Bits 1 - 7: Reserved for future expansion.
