DSL service questions

[pll at lanminds.com]

Hi,

I just discovered that according to both Verizon and Earthlink my 
lines are eligible for DSL service.  This is a very good thing IMO :)

However, not knowing a lot about DSL, I'm curious about how it works.
Currently, I have 2 phone lines in the house, one of which is used 
exclusively for dial-up to Earthlink.  Additionally I have a 
no-longer-active leased line frame relay circuit in the house from a 
previous-but-now-defunct employer.

When subscribing to DSL, do I:

	- use my exising phone line obviating the need for 2 lines
	- convert my dial-up line to DSL, thereby maintaing 2 lines
	  and therefore 2 bills
	- or have them use the old FR line but get to cancel the 
	  dial-up line?

I guess my question really boils down to "is DSL like ISDN" in the 
sense that I can use one line for both simultaneously (b/d channels?)
or do I still need a second line for DSL to run over.

I'd really like to eliminate the second phone line, and ideally the 
ISP.  Though, I'm hesitant to ditch Earthlink, since I've never had a 
problem, and the alternative is DSL directly through Verizon :(

Thanks for any insight!

   but I'm really actively waiting for all my problems to go away.
