What if your company has decided to order adsl from its local telecommumications carrier you call the carrier and find out that your office is located 17000 feet from the nearest co given adsl potenti?

Depends. You need to find out if your local carrier supports ADSL 2+ or not. 2+ DSL can go up to 30000 feet. The speed is dependent upon the quality of the line, but i have installed many 3.0 mbs DSL lines at 17k feet. You should have no problem getting 3.0 mbs service if the carrier has the ADSL 2+ technology in place.
