x2 technical question (not TA)

I've got a question about the modems at the ISP end of things among other things.

As I understand it, x2 relies on the fact that if your telco and ISP only do one analog to digital conversion you can get the 56k downstream.

Here's my picture of things:

The data flows from the net to the ISPs RAS (?) through a "modem" (since there's no A to D conversion is it really a modem?) back out to the telco, over their network, to the local telco CO, it's converted to an analog signal for the last mile, gets to my house where it's converted back into digital data by my modem. (really a modem)

Is this picture correct?
Who provides the data transport from the net to the ISP?
Why to they call the ISP thingies modems? I mean the used to be, but they're not
anymore?

P.S. Is there any way to "add" a post or must you "reply"?
