    DUN line quality

    My local telco seems to have expanded its capacity by inserting A/D converters in the lines, without a care for the fact that an analog modem cannot reach the POP server if there is more than one converter in the connection. The telco wants to sell me DSL service to fix "my" problem.
    Question: are DSL 'last mile' connections more tolerant of line noise than analog connections?

    Well, they COULD be. But DSL is really particular about any kind of line interference, and probably more so - I don't know that the A/D converter would harm the signal but if the line has any static, crackle, interference - performance will suffer.

    Re: DUN line quality

    Thanks. But I'm still both confused and irate, because the first task of the telco when a customer signs up for DSL is to "qualify" the line -- that is, to test it for its ability to support DSL service. Thereafter the telco has to keep the line in service, although both the ISP and the telco refuse to offer any guarantee of a minimum speed that will be sustained.
    Physical testing to "qualify" the line implies that there are written line performance measures. Any idea where one might go to read them?
    What really bugs me is that the telco is dropping the performance of my current analog lines, while promising to give me higher performance if I pay them twice the analog monthly fee. And guess what? - they'll drop the performance of a neighbor's line by searching at a cable junction for a line that qualifies for digital signal support, while sheltering behind a phone contract that apparently obliges them to do no more than to provide dial tone and intelligible analog voice signals. So the telcos can reward themselves by deliberately allowing existing voice service to deteriorate, thereby coercing captive users to switch to DSL at twice the fee!
    Hey - as Woody Allen said - "just because you're not paranoid doesn't mean that they're not out to get you!"

    Sounds like your telco is a real winner (cough cough). Have you considered moving? <img src=/S/laugh.gif border=0 alt=laugh width=15 height=15>

    If they are written down somewhere, they may not be public knowledge. But I would certainly call them and ask. Unfortunately for you in this scenario, there isn't much recourse, outside of perhaps legal action - and that's not a tasty, cheap or guaranteed option.
