Compaq AA-RHGWB-TE manual Installing ATM Adapters, Emulated LAN Over an ATM Network

–Broadcast and Unknown Server (BUS): A BUS handles broadcast data sent by a LAN emulation client, all multicast data, and data sent by a LAN emulation client before the ATM address has been resolved.

Figure 7–1 shows an ATM network with two emulated LANs. Hosts A and B are LECs on ELAN1. Hosts C, D, and E are LECs on ELAN2. The LECS, the LES, and the BUS are server functions resident on the ATM switch (even though they are shown separately).

_____________________ Warning _____________________

Some fiber optic equipment can emit laser light that can injure your eyes. Never look into an optical fiber or connector port. Always assume the cable is connected to a light source.

______________________ Note _______________________

Do not touch the ends of the fiber optics cable. The oils from your skin can cause an optical power loss.
