Unit returns the current highest-priority fault and status codes for the Unit
(hardware), Tx Traffic, Rx Traffic and ODU in the form abcdef, where:
a = Unit faults:
0 = No faults
1 = Power supply fault, +5 volts
2 = Power supply fault , +12 volts
3 = Power supply fault, –5 volts
4 = Power supply fault, +23 volts
5 = Power supply fault, –12 volts
6 = Tx synthesizer lock
7 = Rx 1st LO synthesizer lock
8 = Rx 2
nd
LO synthesizer Lock
9 = Ref PLL lock
E = IP Module
F = EEPROM checksum error
A, B, C, and D are TBD (for future expansion)
b = Tx Traffic status:
0 = Tx traffic OK
1 = No clock from terrestrial interface
3 = Tx FIFO slip
5 = Loss of External Reference
7 = AUPC upper limit reached
9 = AIS detected on incoming data
B = Bipolar violation on G.703 interface
2, 4, 6, 8 and A are TBD (for future expansion)
c = Rx Traffic status:
0 = Rx Traffic OK
1 = Demodulator unlocked
3 = AGC Alarm - signal out of range
5 = RS Frame sync alarm
7 = EDMAC Frame sync alarm
A = Buffer Underflow
B = Buffer Overflow
D = Eb/No alarm
F = AIS detected on incoming data
2, 4, 6, 8, 9, C and E are TBD (for future expansion)
d = ODU status:
0=No ODU faults
1=BUC PLL
3=BUC current
5=BUC voltage
7=LNB current
9=LNB voltage
B=BUC temperature
D=BUC checksum
2, 4, 6, 8, A, and C are TBD (for future expansion)
