Absolutely no noise on the line. PQT very good, it's just shitty E-Side cabling.

I've got a brand new E-side as it's a new build house, . . .

Having now read your posting a number of times, I suspect that the second mention of E-side (coloured blue, above) should really be D-side.  :-\

Absolutely correct  ;D

The E-Side is the reason for the poor speeds!

My sincere apologies, you will know far more about it than I ever will. :-) I'm just surprised at your sync speed given your attenuation figure, which of course takes into account thin wiring. Perhaps your wiring and green cab is rubbish in some other way. Depending on how you feel about the use of terms, do you include crosstalk under the heading of 'noise'? According to Black Sheep iirc, my wiring is the fattest copper, for most of the length at least.

If your noise is ok, then that either means that mine is ridiculously good, or it's to do with modems, filters, cables etc. I don't know what my crosstalk is like. I have no filter at all (no phone), good ultra-short dsl cable, no house-internal wiring, triple-filtered mains supply to the modems just in case and aggressive modems, I believe. So maybe the difference is in there. I've spent a lot of time over the years comparison testing-kit and swapping things over, including making some 'improvements' that are probably pseudo-science and not really relevant but can't hurt.

Can't really do any more. Tried a 7800DXL and 800NL (better and less errors). No filer as it's a new filtered socket, short DSL cable. As mentioned before, the sync at the cab on my E-Side is only about 2.5meg with 6db.

I can get the line to sync at 2.9meg if i resync around 1pm, but it drops out come dusk around 6pm as ambient "noise" increases and the SNR drops to a level causing too many errors.

Hopefully not long till they sort the power out at the cab and we're whistling along on 50meg or so :)

@ejs - No. But no cheating by having a broken line, otherwise you could knacker your own setup to win the prize.

So why would you be interested in people with slow ADSL speeds who could switch to FTTC to get better speeds, but haven't?

An acquaintance in Wales lives in a remote spot, a mile away from the public roads through Forestry Commission land.
OR have done a lot of work over the years to get and keep his ADSL connection working.
I think he said his line was 7 miles long, and on a good day his download speed is still considerably less than 1 Mbs.

So it would seem to be Wales vs Wales at the moment.

A friend of mine moved to a beautiful converted farmhouse in Wales last year and initially their sync speed was somewhere around 100 - 150 kbps with frequent disconnects and unable to hold a connection for long.
Nothing BT could do and still no FTTC from their cab.  I just tried to put their phone no in the BTw checker, but it appears to be down atm (invalid security cert).

My checker says

Distance:-    Direct:          4.97 km
     (appx)*    By Road:    7.3 km


It looks like BT have now marked the line as unviable as its coming up as follows

Fixed ADSL:     0 kbps    (0 Mb)
   DSL Max:      0 kbps    (0 Mb)
   ADSL 2+ :    Not Available    

FTTC is available in your area.
     Speed    Max    Min
     DownStream    No info    No info
     UpStream    No info    No info

Fixed ADSL:     0 kbps    (0 Mb)
   DSL Max:      0 kbps    (0 Mb)
   ADSL 2+ :    Not Available    


They gave up on DSL and now have a satellite connection.
I've been invited to go stay anytime I like, but not sure how I'd cope without a decent internet connection. (jk)
Im not giving their exchange out on a public forum other than to say they are in the northern part of Powys and south of Snowdonia.

This would have put kitz' friend in a good position were it not for the fact that their service was abandoned. My lines are the very same by-road length, but I must have thick copper, as Black Sheep said, coupled with a relatively low noise per metre environment otherwise I would never get anywhere.

The issue with the BT Wholesale checker is that even though they were warned months ago, they continued to use an SHA-1 signed SSL certificate. This means that Chrome and Firefox now block them by default. There are ways to get to it but until BTW update to a more secure hashing algorithm, they are blocked by default.

My closest neighbour gets about 1.5 Mbps, ADSL. Over the years I've helped him on many occasions, when he called up to say it had got unstable.  In those days, I got around 3-5Mbps, hence why I felt I could assist.

Come fttc I explained to him 'Your problems are over, you can now get 30Mbps or more'.   He wasn't interested, and still isn't.   All he wanted was stability, not speed, uses internet mainly just for email and occasional browsing.   And he has a point.   :)

Yeah but FTTC would likely bring more stability.  As the shorter line length means any strong tones completely outnumber weak tones, and FTTC is generally more resistant to external noise as well as removing the E side of the pair from the equation.  This is especially the case if its a hauwei cabinet when g.inp can be enabled.

Aggressive DLM also brings stability.   So if you're not concerned about speed, as are quite a large number of people, a long line with BTW DLM and a 15dB target and 1-2Mbps fulfills all requirements.

I can submit a candidate myself. The thinkbroadband speed test results map shows quite a few horrors in Skye, but one user in the tiny hamlet of Lib is enjoying 160kbps downstream 240k upstream, and the entry says 'BT Wifi', whatever that means.

I had a repair only yesterday with the EU receiving just under 200kbps with an attenuation of 84dB ...... the highest attenuation I have personally ever seen/worked on.

I was further amazed by the fact that my JDSU actually synched up on this long-line !!!!
