STABLISHING
Asynchronous Transfer Mode (ATM) is a connection-oriented transport
service, much like a telephone. Unlike Ethernet, where data is sent out on
a common bus, ATM requires that a path or virtual channel be established
to carry the call from the source station to the destination station before
data transmission can begin. A virtual channel may be established either
manually through management or automatically through the processes
of signaling and routing.
