RxAGC
This indicates that the Receive Input power level is either too high or too
low and the Automatic Gain Control to normalize this signal level has railed
high or low, as the signal level is outside of the specification provided in
Section 1.3.6
X X X
EsNo
This indicates that the minimum Es/No (set in Section 6.2.2.3.4) has been
reached and the local demodulator Es/No level is at or below this
threshold.
X X X
LNB
This indicates that the high or low current limits for the LNB have been
met.
X X X
Ref
If an external reference is selected (Section 6.2.2.12.1), this indicates that
the external reference being asserted to the modem does not meet that
selection.
X X X
DeCompInv
This indicates that the decompression (On/Off) as selected (Section
6.2.2.6.2) does not match the incoming data: i.e., Decompression is ON
but the data is not compressed, or Decompression is OFF but the data
appears to be compressed.
X X X
AUPC
This indicates that the Tx output power has reached the Nominal + Range
sum (upper limit) and the modem can no longer increase its Tx output
power, but the remote reported Es/No is still lower than the Target Es/No.
X X X
EthLink
This indicates that an Ethernet Interface is selected using the CONFIG: Intf
menu (Section 6.2.2.4) as the active interface, but an Ethernet cable with
Ethernet traffic has not been detected on this physical port.
