Being someonewhat familiar with the design of ATM networks, I can tell you
that it is not correct. Your basic ATM gets two to three connections - one
being a data access line, the other being a regular alarm line. The data
access line is POTS, DS0 or, ISDN. The alarm line is POTS (the funny part is
that certain large banks when buying other banks forget what the other line
is used for and put a disconnect order on those creating lots of mess). The
transaction data is never supposed to travel on any non-dedicated network.
