Any data service is limited by its upstream bandwidth. And, as odd as it may seem, there have been times where BellSouth has provisioned a FITL cabinet with T1 lines which were running on copper. That's very, very rare these days and I think I only heard of that in Mississippi.
I don't think I ever provisioned a FITL cabinet with anything less than 4 T1 lines, but that's just enough for the POTS service. It's possible that the DSL solutions were, in the early days, fed with one or two T1's. ; When I completely left the provisioning world, though, it was rare that we provisioned a cabinet with anything less than an OC1, and there were times where we provisioned it with an OC3. I think, but I'm not sure, that the newer cabinests are being provisioned with gigabit ethernet over fiber as opposed to muxes which provide T1's and OC services. I'm completely out of that world today, so it's hard for me to be sure.

From what I've been told a couple
times the speed of an IFITL connection is directly related to what's
feeding it. In most cases there's just a T1 being used as the feeder
line which, of course, keeps BS from being able to offer the higher speeds
available to users in places wired using copper only.
There is still PPPoE involved; the router
holds the login info though so you won't have to do anything on the boxes
connected to it.

Fiber
BellSouth has
experimented with fiber all the way to the house, but only in a few
areas. For the most part you're right, though, that he's more likely to
have FITL or IFITL which is fiber to the curb.
There is a difference between FITL and IFITL. It's been at least a year
since I've dealt with either, but I believe IFITL includes video and also can
provide very high data speeds (far exceeding 1.5mbps). IIRC, IFITL makes
use of an additional part of the spectrum on the fiber which allows for the higher
speeds, but it's far more expensive and BellSouth decided to only implement it
where it was able to obtain cable TV franchises. Data over IFITL is not
ADSL, but I cannot remember excactly what technology is used.
FITL looks the same from the outside, in that it is still fiber to the curb,
but once inside the pedestal the electronics are different. In the early
days of FITL and broadband there was a real problem with the ADSL cards burning
up. That problem has been solved, of course, but I think those areas
still lag in terms of speed, despite having fiber within 500 feet of the
house. I believe FITL is actually ADSL.
Then there are those of us who live in the areas where BellSouth actually
experimented with coax. ; It's strange to me to look up at my house and see
two coax cables running to it. I don't think they did much experimenting
with broadband over coax, though.
Of course, I'm now using Comcast and Vonage now, so none of it matters to me
anymore!

I ran my own Cat5e from the house box to the closet where my router lives.
The tech just connected everything at both ends and all was well.
And, yes, you are stuck at 1.5MB when using IFITL and there is no time frame
for an upgrade (I've asked SEVERAL times). If it wasn't such a pain
in the
butt I'd have switched to cable for 6MB long ago. I do love the fact
there
is no modem to deal with when using IFITL though...

The fiber will terminated with a converter in a box. It will be copper
inside the house. Run your own wire3 from where you want the jack back
to the box and have the DSL tech connect it to the converter.
