Extended reach regrades

Hi,
I was rejected prior to the 6th of Sept by BT for even basic service on grounds of distance. Now I have 512kb.

Is there anyway to tell if higher speeds (regrade) to 1 or 2mb is likely to be succesfull?

Are any of those "db" and SN parameters in my router stats an indicator?

Thanks, Graham

Extended reach regrades

1Mb has a line limit of 60dB (the same as the old 512K limit) with 512K no longer having a limit. That fact you were rejected for 512K previously suggests you were above the 60dB limit (or your SNR was too low) then so it's unlikely you would get 1Mb now.

What does you router say for attenuation and SNR?

This is what I see in the router diags, Down followed Up

Connection Speed 576 kbps 288 kbps
Line Attenuation 63 db 31.5 db
Noise Margin 12 db 18 db

Yep, 63dB is too high for 1Mb and that was the reason you were rejected originally for 512K.

So 512K is all you are able to get unless BT relax the 1Mb figures which are unlikely for some time.
