I went to a guys house to installa phone line for DSL yesterday. Well, there were multiple lines coming into the house with none of them active. How do you tell which one is the DSL line?

By far, the easiest way is to purchase a butt set with the ability to detect the presence of DSL signal. Not cheap, but it sure does save a lot of time.

1. call the service provider
or
2. hook a modem up to each line until you get a sync lite

Michael:
DSL is a signal that literally rides along the cable pair that provides dial tone. Even if this pair is half-open, the DSL signal gets through because it is only using the cable pair as the equivalent of an antenna.
Yes, it's true. The phone line carrying DSL may be out of order due to an open, yet the DSL still works. Pretty amazing if you ask me.
Your options as a technician are limited. Either invest in a butt set that can detect the presence of DSL signal on the line or do what the other posters have said.
You will spend much less time doing it this way than calling the service provider. Chances are, they don't even know where the signal is. A technician is only as good as the tools that he has at his disposal (assuming that he knows how to use them).
I do have to ask: Are you a technician or are you just learning? Your questions appear to be basic in nature. No offense intended, but it helps us to help others if we understand the extent of a posters' knowledge of the industry.

Not to well versed in DSL. I'm glad the client changed his mind about me doing the job. The unit had been remodeled and had no line running into it. One of the demarcs was active with DSL but not too sure which one. He changrd his mind about me doing the job because he didn't want me drilling into the wall.
