Carl, every wire in your house can be connected to the #. As I said before, ideally you have a particular wire (actually a pair) going from dmarc straight to your preferred dsl jack, one that isn't spliced in attic to branch off to other jacks. If this is the case, make sure you put a filter at the dmarc. All your "regular wires" should connect to the 2 posts of this filter. Your dsl wire will connect straight to the dial tone source at dmarc. The filter has 2 leads coming off it and connects straight to dial tone source as well. The filter enables you to talk and surf at same time, w/o hearing the hissing. If your wiring is spliced in attic and going to different jacks, and the dsl will be on one of these, you'll have to have a filter at every jack where you use a phone.
If the latter is your case, do yourself a favor, go to Home Depot, etc and pick up 100 feet of CAT5 for $12 and a $2 jack. Run it yourself from dmarc to preferred location. This makes things so much simpler, especially when troubleshooting, which invariably happens at some point. You know you can always mail me for details. Buy my ticket to Modesto and ...
btw, don't cancel your 2nd line until dsl up and running
