SNR/Attenuation

    I haven't really paid that much attention to the stats on my line until
    recently as our new replacement router provides the stats. I got a little
    confused with figuring them out at first because nothing seemed to match
    up with what other people were posting here. People seem to have much
    lower SNR and much higher attenuation that I do..would I be right in
    thinking that the following figures are actually pretty damn good for a
    line?
    Downstream Upstream
    SNR Margin 39.7 31.0 dB
    Line Attenuation 11.6 7.0 dB

    The main reason I'm asking is that I may upgrade from 512 if I get the
    money. From what I understand with the limits of just over 40dB for 1/2
    Mbit then the attenuation of 11.6 is well within the bounds and
    remarkably good..

  2. I have also been wondering about this. My Speedtouch router gives me the
    following information:

    Attenuation (dB) up/down = 31 / 53
    Noise Margin (dB) up/down = 26 / 31

    The BT checker says that I can only get 512 due to the length that I am from
    the exchange but I was wondering if my line is good enough to support 1MB
    assuming I could find a ISP that does a manual order?

    Compared to yours my line seems noisier though...

    Assuming the routers readings are accurate, you won't get 1MB at the
    moment - even with a manual order.. you are quite far out

    However, if BT do change the 1MB limit to <60dB later this year, you will
    then qualify.
