Unit returns the current
highest-prority 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
9=Ref PLL Lock
F=EEPROM Checksum error
6,7,8,A,B,C,D,E are reserved for future expansion
bb =fault codes for slot#1 can be Tx or Rx Traffic status
cc =fault codes for slot#2 can be Tx or Rx Traffic status
dd =fault codes for slot#3 can be Tx or Rx Traffic status
ee =fault codes for slot#4 can be Tx or Rx Traffic status
TX Traffic status:
00=TX Traffic OK
01=No Clock from Terrestrial Interface
03=TX FIFO Slip
06=TX Synthesizer Lock
07=AUPC Upper Limit Reached
09=AIS Detected on Incoming Data
0B=Bipolar violation on G.703 Interface
0F=TX EEPROM Checksum Error
12=Power supply fault, +5 volts
13=Power supply fault, -5 volts
