CONFIGURING THE ATM VIRTUAL CIRCUIT

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.
