3.1
Frame Relay
What follows is some background information on frame relay. Please skip to section 3.2 Setting up the
WAN link to begin configuring your Prestige right away.
Frame relay is a form of packet-switching technology that routes frames of information from source to
destination over a switching network owned by a carrier. Suppose a corporate network has 4 sites, site A,
site B, site C and site D (as shown in the next figure) and you need to interconnect these sites with both data
links and voice lines. As data traffic is relatively continuous throughout the day one solution (though
inefficient) would be to set up dedicated leased lines connecting each office as shown in Figure 3-1.

Dedicated Leased Lines – Multiple Sites
The frame relay solution would be to rent short dedicated leased lines to the carriers frame relay access
point and then the carrier programs virtual circuits into the network between your sites.
