ONFIGURING THE
V C
IRTUAL IRCUIT
As your LAN computers access the Internet via the ADSL
Barricade, data is exchanged with your ISP through a complex
network of telephone switches, Internet routers, servers, and
other specialized hardware. These various devices communicate
using a common language, or protocol, called Asynchronous
Transfer Mode (ATM). On the Wide Area Network (WAN) that
connects you to your ISP, the ATM protocol performs functions
like those that the Ethernet protocol performs on your LAN.
This section describes how to configure the ATM virtual circuit
(VC). The VC properties define the path the ADSL Barricade
uses to communicate with your ISP over the ATM network.
Viewing Your ATM VC
To view your current configuration, log into the Configuration
Manager, click the [WAN] tab, and click [ATM VC] in the task
bar. The [ATM VC Configuration] page appears, as shown in
Figure 33.
