they've got dsl now without phone line.

Oh, but is DOES come over a "phone line". It just has no dial tone.

That is called "Stand Alone DSL".

It is delivered over the exact, same pair that runs to that station -
with NO dial tone on it.

Troubleshooting "dry" DSL is a royal PITA. I often would "layer" C.O.
dial tone (talk line) on the pair during repair. Otherwise, waiting for
the DSL tester to train-up (sync) at each test point in the circuit was
time consuming and frustrating. With dial tone, it's MUCH easier: No
dial tone? The pair is open or seriously faulted somewhere.
