Does dropping line speed to 256 help with poor SNR

    I have a 512 line which shows SNR varying between 2 (daytime) and 19
    (during night) the low SNR figure believed to be caused by local
    interference (the last 100 metres of the line is carried over a
    college campus internal phone wiring). Would dropping the line speed
    to 256 make a significant difference in particular reducing the number
    of diconnections.

    I dont know if there are any genuine 256k services. When I had a 256k
    account it was a rate-limited 512k line.

    Zen (the ISP in this case) say their 256 service does sync at 256.

    It worked in my case - switching from 512k to 256k with Zen brought my
    connection from hardly-ever working to almost-always working. I am on a
    long line, with an indicated 63 dB of attenuation and a downstream noise
    margin usually between 2 and 9 dB at 256k. Router is a Netgear DG834.

    The ZEN service is a true Home250 service and Sync's at the speed as you
    have stated. Most of the other ISP's aren't offering this BTW product.

    Is there any particular reason why Zen can do this, and other BT-based
    ISPs don't (or didn't)?
