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....
