9 Configuring the ATM VCC

As your LAN computers access the Internet via the Best Data DSL542, 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 Ethern et

protocol performs on your LAN.

This chapter describes how to configure the ATM virtual channel connection (VCC). The VCC

properties define the path the Best Data DSL542 uses to communicate with your ISP ov er the

ATM network.

To view your current configuration, log into Configuration Manager, click t he WAN tab, and then

click ATM VCC in the task bar. The ATM VCC Configuration page displays, as shown in Fig ure 34.

The ATM VCC Configuration table displays the following fields (contact your ISP to determin e

these settings):

Field Description

Interface The name of the lower-level interface on whi ch

this VC operates. The low-level interface names

are preconfigured in the software and identify the

type of traffic that can be supported, such as data

or voice. Internet data services typically use an

AAL5-type interface.

Vpi, Vci, and Mux

Type These settings identify a unique ATM data path for

communication between your ADSL/Ethernet

router and your ISP.

Max Proto per

AAL5 If you are using an AAL5-type of interface, this

setting indicates the number of higher-level

interfaces that the VC can support (the higher

level interfaces can be PPP, EoA, or IPoA

interfaces). Contact your ISP to determine which

connection protocol(s) they require.

Actions Displays an icon ( ) you can click on to delete
