Example 1: IP Routing Network—ATLAS as the Central-Site Router
Example 1 (see Figure 4-2) depicts a typical IP routing network using an ATLAS
as the central-site router. (This ATLAS unit is the ATLAS 800
PLUS
with a frame
relay upgrade.) The central-site ATLAS terminates a full T1 (F-T1) frame relay
connection from the XYZ service provider, and the internal router terminates the
IP traffic. A TSU 100e with a router module is located at each of the two remote
sites. To re-create this example, follow the five-step process discussed below.
