What type of DSL circuit is this for? Is it a "legacy" ADSL line? If so, prepare for an uphill fight. As a side-effect of their VDSL2 service, they've increased by several orders of magnitude the amount of crosstalk that happens between your demarc and the neighborhood fiber POP. If you're a subscriber to the new service, this isn't a problem, but if you have the old ADSL service, the signal from the DSLAM is coming from much further away and is competing with crosstalk from the neighborhood fiber POP in the copper bundle. I went through this last spring at my house, and was unsuccessful in trying to convince Qwest (at the time) to remedy the situation. Is is rumored (on broadbandreports.com and elsewhere) that Century Link is not putting any effort towards helping out ADSL customers with poor SNR as an attempt to get them to upgrade to the VDSL2 service. -Erik
