Thanks for looking into it for me! I've pm'd you

It is down to the length from Cabinet to house ... if your estimate is correct and the cable follows the route you believe then the estimate is well down. At 600m you should be looking at 40Mbps or above.

See what Mr S comes back with after you have PM's addresses to him.

Exchange and new cabinets are in Market Street, and the two postcodes for the homes are a couple of hundred metres apart, so if the cables are routed down the optimal route then estimates are wrong,

BUT

Looking at the maps there is no guarantee that the cable routing follows the logic that would be used today, ie. shortest route. This is particularly the case for old EO conversions, so I can easily envisage a scenario where the route may include Duff St and Souter St and this would match the estimates that are being given in terms of line length.

Only way to really know is to order or kidnap Openreach staff who have access to the full in ground copper records for the area to confirm exact routing.

Does't the attenuation tell us what we need to know here? Line length ~1km?

If the attenuation is suggesting 1km, then it is likely the line is not routed optimally, and thus agrees with what I suspect may be the case from a peek of area on map and streetview.

1km should manage actual speed tests around 20 Mbps, but it does not take much variation for this to dip into the 15 Mbps area.

75% happy that the estimates are reasonable and that the original poster is not in line for 70 Mbps and faster.

Looks like the estimates are right and my side of the street is probably out of luck until G.Fast or something similar is rolled out? Oh well, the wait continues!

Edit: It's really frustrating that 3 cabinets service my street and 2 are offering 60+ Mbps speeds, it's typical that mine is the one that doesn't

Edit 2:

In reply to a post by MrSaffron:

If not 70 Mbps do you think there's any chance of fibre being higher than my current 16.2 Mbps?

In the meantime, you should easilty be getting 20+ meg sync on ADSL2+ @ 16 db attenuation - i was gettiing nearly 18 meg with TT on my 29db attenuation line (@6db SNR)

1) if not already done, ask Talktalk to put you on a "24FSNR6" profile - this will put you on a fastpath 6db profile as i suspect you're still on TT's default 12db snr. Do this via the TT forums.

2) To squeeze every bit of speed from your line, consider using an Draytek 120 v2 ADSL2+ modem with your router. In my experience this gave me nearly 2 meg higher sync than a broadcom chipset based router. If it doesn't improve your speed then you can always send it back to Amazon for a full refund.

You may not miss VDSL2 after all

Thanks for the advice! Unfortunately my line has always underperformed compared to the stats, my line actually syncs closer to 12 meg normally and I had to tweak my SNR a bit to to get the speed up. I'm on the 24FSNR6 profile with my SNR tweaked down to 3 it never drops connection and has a very low error rate even at SNR 3 but it syncs low for some reason.

I've had BT out twice over the years to look at it but they said everything was fine, they repaired some damaged wiring before the master socket (in the 80's they ran the wire under the carpet beside my front door, decades of traffic meant bare wires and disconnections every time we walked past!) & added a BT80RF3 where the phone line comes in to my house (to reduce any possible REIN? interference) but neither have helped at all. The last engineer even went as far as to say 12 meg was the highest speed available and basically said I was lying when I said my neighbour was syncing close to 19 meg :/

My internet history on this line has been a nightmare fibre was the saviour I was waiting for but no dice. G.Fast is the new hope!
