THe anomaly with the Kitz checker is that you put in your attenuation and it "calculates" the distance from the exchange. Kitz tells me I'm 2.8km from my exchange but I know it really is only 1.6km by road.

This indicates that the quality of my line is rather less than it could be. Cannot compare with neighbours as most are on expensive cable but it is another factor in the search for greater sped although I am quite happy with what I get.

Calculating distance by attenuation is much more accurate than guessing the route of the copper, which never follows the same route as the road, as the crow flies or otherwise.

Where I used to live I was less than 100 yards from the exchange by road. However I know that I was fed from a cabinet 1/4 mile in the other direction and that my line length was well over 1/2 a mile.

Guess you have tried the normal things such as optimising your internal wiring and using different filters etc. ?

I certainly improved downstream sync and stability by using a filtered faceplate and a cat5 rj11 adsl cable, not by a great amount when I was on adsl1 but it may be more significant now that I'm on adsl2+

Very true Professor.

I live 200m from exchange but my line turns right instead of left as it exits the Exchange and does a 2km tour of town before it hits my Cabinet opposite the house. Therefore I end up with an attenuation figure of 29 and a sync speed of 14385ish!!

WelshWArrior,

Just out of interest what is your downstream SNR margin and I guess your adsl2+ connection is interleaved?

Also did you initially have any problems with PN capping your upstream sync?

Hey 4M2

I'm at work right now but I checked my Router Stats last night and it was 6.5. The connection is still interleaved - not had it switched off. The upstream was initially capped but that's default for all accounts until you request it to be uncapped.

It only took a couple of hours to get uncapped.

Thanks for the info

No probs - if I remember I'll post my full router stats later on

Cheers - thinking of a possible move (back) to PN (30 day minimum term) myself on a Market 2, 21CN WBC enabled exchange, just don't want any hassle getting the upstream sync uncapped though. Might go for line rental also since BT offshore call centres can be a nightmare when it comes to getting any issues sorted out...
