My understanding is that SBC will provide "DSL filters" (for a price) to allow phone or fax usage while connected -- guess this means it is ASDL.

Well, it is basically the same set of wires. I believe a standard phone uses just 2 wires. There are like 8 in there.

To be more precise... Regardless of how many wires are in the cable that comes into your home, the phone company handles them by pairs. POTS(*) takes one pair. ADSL runs POTS *and* DSL over the *same* pair; the breakout is done with a filter, then it appears as separate jacks to the customer. Other forms of DSL require a separate 2nd pair to be used, in which case there may also be (depending on the filed tarif) an additional base charge for the 2nd pair's POTS dialtone).


(*) POTS = Plain Old (analog) Telephone Service/System
