My 'show errors' does not show the dB Line Quality...different version of CBOS?
Mine is CBOS v2.4.3
'show int wan0' does show me lots of information, but most of it I don't really
know if it is good or bad. Would anyone mind interpreting for me?
I've pasted the output of both commands below. Things that I see as potential
important measures are:
- crc_errors seem to be causing outages. Is that common?
- my upstream data rate is reported as 256 Kbps. I ordered DSL Deluxe
(650 Kbps UP / 256 Kbps DOWN), and Qworst is billing me for
that!
- there are some measures of dB reported in the 'show int wan0' seciton,
but I'm not sure which is most important. It shows that my
local attenuation is 35.5dB (Good?) and remote attenuation is
31.5dB (not so Good?).
