Figure 1.6 LAN Emulation Components
Note: The router shown in Figure 1.6 is not a LAN Emulation component, but
would be required should a device on one Emulated LAN need to communicate
with a device on another Emulated LAN.
LAN Emulation and Avaya Devices
LAN Emulation components are implemented in ATM devices. The LAN
Emulation standards do not specify how each vendor implements each of these
components.
Avaya provides a wide range of ATM equipment, and the following example is just
one way in which you can implement an Emulated LAN using Avaya devices.
An Example:
• The Avaya M770 ATM switch incorporates the BUS, LES and LECS
components. These components are known collectively as LANE Services.
• The M-ACC module has 16 LAN Emulation Clients (LECs); one for each of the
Virtual LANs (VLANs) supported by the module.
