Description of Arguments
or Response
to Query
External Reference Frequency, where:
0=Internal
1=External 1 MHz
2=External 2 MHz
3=External 5 MHz
4=External 10 MHz
5=External 20 MHz
Example: ERF=0 (External reference not used - uses internal)
Unit returns the current fault and status codes for the Unit
(hardware), Tx Traffic and Rx Traffic, in the form abcd, where:
a = Unit Faults:
0=No faults
1=Framer FPGA Load
2=Power supply fault, +1.5 Volts, Framer Card
3=Power supply fault, +1.5 Volts, Interface #1
4=Power supply fault, +1.5 Volts, Interface #2
5=Power supply fault, +3.3 Volts, Framer Card
6=Power supply fault, +5.0 Volts, Framer Card
7=Power supply fault, +12.0 Volts, Framer Card
8=Power supply fault, -12.0 Volts, Framer Card
9=Power supply fauilt, +18.0 Volts, Framer Card
A=FLASH Checksum
B=FEC1 Load
C=FEC2 Load
D=Interface #1 Load
E=Interface #2 Load
F=192 MHz PLL
G=External Reference
H=Framer Card Temperature
I=Modem Temperature
J=Cooling Fans
K=Interface #1 Removed
L=Interface #2 Removed

ERF? ERF=x
FLT? FLT=abcd
d=Change in fault status
since last poll.
Note: Each section has
faults listed in order of
priority. For each
section, only the highest
priority fault is returned.
There maybe multiple
faults for each section,
but only the highest fault
is returned.
