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 Ethernet
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 over the
ATM network.
Viewing Your ATM VC Setup
To view your current configuration, log into Configuration Manager, click the WAN tab, and then
click
ATM VCC in the task bar. The ATM VCC Configuration page displays, as shown in Figure 34.
Figure 33. ATM VCC Configuration Page
The ATM VCC Configuration table displays the following fields (contact your ISP to determine
these settings):
Field Description
Interface
The name of the lower-level interface on which
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 (
