I'll check the network interface tonight, but I'm pretty sure that there's no filter anywhere
near the house. IIRC, the installer said something about fiber to the pedestal, and hooking
the Y-K pair at the pedestal right to the DSLAM. Several years back a company put fiber in
the neighborhood, then went under, then SBC bought the "cable plant" of the company. I know
that my neighborhood is *VERY* different than other SBC-served DSL areas.
Yep. That's FTTC - Fiber to the Curb. It uses a separate pair from
the curb to your house. (Since it's only the local drop, Assigning
Dept. does not have to track that at all.) That explains what you
are saying. It's not ADSL as the masses get at all. The data feed
to the miniDSLAM of some kind in the pedestal comes up separate
channels from the phone lines of you and your neighbors.
Such may use ADSL for the last 100m. The reason, I suspect, is the
cost of the CPE is so low.
As you observe, it makes little economic sense -- the costs are
sky-high and it still "looks" like ADSL to Jill Winecooler.
