Telephone connection problem with DSL

unplug everthing from all jacks in the house. call your # a couple of times. if the line rings, plug everything in 1 at a time, but call again after each hook up. if the line goes dead or is busy, that phone you just plugged in is the problem. [ a short in the phone, computer, answer machine, or any piece of equipment plugged into the phone line.] if the line is busy when everything is unplugged, call your phone company. there maybe a problem with your inside wire.there also maybe a box [called a nid] inside your basment/garage or on the side of your house, where you can plug your phone directly in, bypassing all the jacks in your house
hope this helps.
