Channel Setup
This chapter shows you how to set up channels on your Prestige.
3.1 Introduction
The Prestige converts frame relay/HDLC (High-level Data Link Control) frames to ATM (Asynchronous
Transfer Mode) cells from the LAN to the WAN and vice-versa via channels. The encapsulation type you
select, when configuring individual channels, determines the how frames/cells are converted.

use. To learn more about channels and the topology of VCs (Virtual Circuits) refer to the
