Oscar,
ATM is a WAN technology mostly. Think of it this
way,
X.25 can trunk over Frame Relay
Frame Relay can trunk over X.25
Frame Relay can trunk over ATM
SMDS can trunk over ATM.
ATM can trunk over none of these WAN technologies.
because they don't support Quality of Service.
You can do Frame Relay over ATM (Called Network
Interworking) in which you have Frame Relay on
both ends of the network with ATM in the middle,
or you can do Frame Relay With an ATM end System
(Called Service Interworking) where Frame Relay
is on one end and ATM is on the other.
ATM isn't real popular in the LAN environment
because of gigabit ethernet. However I'll think
you may see this change sometime in the future.
