I don't know the details (and probably shouldn't mention them if I did) but they ATMs effectively talk with the mainframes for any mainframe-based transactions, but the Tandem/HP is always there, and "stands in" for the mainframe if anything slows down communication with the mainframe transactions. Because of the Tandems, the ATMs are never "offline". The Tandem applications go into some sort of "store and forward" mode when communication with mainframe's transaction servers gets bogged down for any reason.
