A VLAN in the CoreBuilder 7000 family ATM switch is defined simply as
an Emulated LAN together with all Ethernet segments and servers
attached to it. The Ethernet segments are represented in the ELAN by
LECs. Figure 55 shows a diagram of such an ATM-based ELAN. The LECs
and the application server are part of the ELAN and the Ethernet
segments are external to the ELAN.
