Stalagmites and stalagtites in DSLStats
« on: August 16, 2013, 06:58:50 AM »

Something I've noticed, but never have before is that the FEC graph appears to show upstream trace rising from the bottom, but downstream hanging from the top.

I'm confused as to why.

Try switching the CRC graph to a logarithmic Y axis (it's a button underneath the graph) to see what it looks like then.

Done for both CRC and FEC with result as attached. Does that now look OK?

It looks as though you have a rather noisy line, but there's nothing particularly noteworthy there.

Yes, that's pretty good for 48 dB attenuation (and the graph looks fine too). :)
