DSL-302G ADSL Modem User’s Guide
ATM VC Configuration
When computers access the Internet using the Modem, data is exchanged with your network service provider or
ISP through a complex network of telephone switches, Internet Modems, 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 channel connection
(VCC). The VC properties define
the path the Modem uses to communicate with your ISP over the ATM network.
To view your current configuration, log into the Configuration Manager, and then click the ATM VCC button in
the Bridging folder. The ATM VCC Configuration page displays, as shown below:

Additional Virtual Connections
In order to use more than one PVC setting, it will be necessary to define one or two set of parameters for each
virtual connection. First use the ATM VC Configuration menu to define new AAL5 settings. All additional
PVCs must be added using the ATM VC menu. For connections that do not use PPPoE or PPPoA, it will also be
necessary to use the EOA Configuration menu to establish Ethernet over ATM settings for the PVC adding in
the ATM VC menu.
To define AAL5 settings for a new virtual connection, click the Add button. To modify an existing AAL5
setting, click the pencil icon (
) for that set. When you choose to add a new set or modify an existing set, a
new menu appears (see below). To delete an existing AAL5 setting, click the trashcan ( ) for that set.
