As a small clarification, when you say IP, do you mean over the public
internet, or on a private IP network? I'm going to guess the latter, but
thought I'd ask...

I've set up a few ATMs.  I have used DSLw+ & STUN on 25xx ciscos and 
FRADs.  I have also seen modems used.  The machines themselves all ran OS2, 
but some banks were talking about moving to NT (this was before Win2K).

When they used IP, they did use cisco, but they did not all use IP.  That 
said, I did most of this many years ago (remember - ianai :), and the 
"newer" stuff was almost all IP.  It would not surprise me if the majority 
of contemporary ATMs use IP.

It would also not surprise me if Citibank has a lot of old ATMs that use 
4.8Kbps modems.

Somehow I think they would be extremely reluctant to tell anyone what they 
use inside their ATMs....
