    Lousy looking stats !

    The other pair are spare - leave them as is as they might be handy to have in the future (they'll probably never be used but always handy to have them available in case of cable damage etc - avoids unnecessary cable runs).

    Your line attenuation is very high, basically there is a high resistance on the line. This can be for instance a very long line, or it can be a line filter on the modem line, or a line filter installed the wrong way, or a conventional phone without a line filter.
    It might be worth looking at the values once you've disconnect ALL OTHER EQUIPMENT from all other available sockets in your home. This might pinpoint a source of the problem. It might also be worth to connect a phone to the end where you have your DSL modem. If you can hardly hear the dial tone or the other party you've got some low & high frequency problem, such as a high resistance. If the phone is fine, but only DSL is affected its more likely a selective high frequency problem, such as filter, unfiltered phone somewhere else on the line.
    1. Check that your filters are not faulty.
    2. Check your filters are installed correctly.
    3. Its possible that an extension cable has become worn or has a break in it.

    thanx lads, the broadband started given me trouble when eircom upgraded my line to 2meg, rang them today, they said to plug the modem into the phone socket directly without the filter and then ring them back from a mobile and than check the line, they said im not getting all the frequency on the line so an engineer will have to come out, dont know whats causing the high Line Attenuation i only live 200 meters from the exchange and i tried a new filter, modem and cables and no change.
