Configuring the ATM VC
The device is pre-configured with an ATM VC interface called aal5-
0. You may need to change the default VC values associated with
the interface to values assigned by your ISP.
To view the current values, log into Web Configuration, click the
WAN tab, and then click
ATM VC in the task bar. The ATM VC
Configuration page displays:
Figure 15. ATM VC Configuration Page
Note
The Quick Start instructions in Chapter 2 also include ATM
interface configuration via Web Configuration’s Quick
Configuration page. You can use either page to configure the
required values.
The ATM VC Configuration table displays the following fields.
Field Description
Interface
The name of the ATM interface to which these VC
properties apply. The ATM interface names 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/ADSL2+
Ethernet Modem 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 type they require.
Actions
Displays icons you can click on to modify (
) and
delete (
) the associated interface. You cannot
delete an ATM interface if another protocol such as
PPP, EoA, or IPoA has been defined to operate over
the ATM interface. You must first delete the higher-
level interface.
