What you are describing is common setup for DSL add-on. Do you have the filters on the phone jacks?
The DSL is at a higher frequency and the filters block that from your phones,fax etc.
If you are talking about crosstalk on the voice lines, I don't think that is a DSL problem.

Here is a good site for DSL info.
