I'm S.Step on DSLStats I dont know what half the stuff is to be honest, ill have to read through the http://www.kitz.co.uk/adsl/linestats_explanation.htm again.

[roseway]

A small correction if I may: you're S.Step on MyDslWebStats (MDWS). DSLstats is just the local program which can feed data to MDWS. There's also HG612_Modem_Stats for Windows, which can also feed data to MDWS.

[S.Stephenson]

Well as far as I can tell my line seems good, can anyone who knows this stuff shine any light onto any potential issues?

[roseway]

Your connection seems to be stable, and error rates are OK. Your connection speeds are probably reduced somewhat by crosstalk, and G.INP  would give you a boost, but there's nothing to be concerned about.

[S.Stephenson]

Id imagine crosstalk is a major factor in my area as before FTTC DSL was 2mbit/s tops, that and it been available since 2012.

Just seems strange to have 60mbit with 14.1 attenuation when I see all the lucky people with 17+ with max speeds still, just like I did back in 2012.

At least I'm <20m from my DP, roll on g.fast.

I think i saw interleave depth 1 somewhere, i assume that means i'm on the fast profile?

[Dray]

Did you upgrade to the latest firmware, B030SP08?
Are you connected to an ECI cab?

I'm using B030SP06, and i'm on a ECI cabinet.

[Dray]

Ah yes, unlucky - no G.INP for you, which would fix most of your problems

Id imagine crosstalk is a major factor in my area as before FTTC DSL was 2mbit/s tops, that and it been available since 2012.

Just seems strange to have 60mbit with 14.1 attenuation when I see all the lucky people with 17+ with max speeds still, just like I did back in 2012.

That is indeed quite a drop from your potential speeds. I had a line of 16.x dB, whose attainable speed dropped from 90Mbps to 78Mbps over 2 years, all due to crosstalk. Yours seem to be hit even harder. The amount of crosstalk seems evident on the "Quiet Line" graph (aka QLN), which shows how much noise your modem can detect on your line before you sync with the DSLAM. The values shown indicate high noise (a *really* quiet line would register -140dB), but the pattern is right, and the noise is balanced across he spectrum.

On the positive side, you aren't being hit by errors, so you aren't likely to receive the double-whammy of DLM reducing your speed even further!

[NewtronStar]

So the QLN graph is a now a good indication on how much crosstalk there is on a circuit 

[Bald_Eagle1]

So the QLN graph is a now a good indication on how much crosstalk there is on a circuit 

I think it has always been an indication as to how 'noisy' a line is - not always due to crosstalk.

For my own connection, I saw a gradual deterioration in the QLN graphs, which indicates gradual increases in 'noise' that are most likely to be the results of increasing crosstalk.

For comparison purposes, see the attached graphs using data for my connection from November 2011 & from today.

Back in 2011, US data wasn't reported by the HG612 modem, but the changes (deterioration) in DS QLN are pretty obvious.

The result is that DS sync speed gradually went from 30 Mbps+ to around 22 Mbps.
