virtual circuit (VC) properties of the ATM VC interface identify a unique path that your

ADSL/Ethernet router uses to communicate via the ATM-based network with the

telephone company central office equipment.

The higher-level protocol interface(s) operate "on top" of the ATM VC interface. The

higher-level interface handles the protocols needed to log onto and exchange data with

the ISP's access server. ISPs can use several different protocols, including the

Point-to-Point Protocol (PPP), Ethernet-over-ATM (EoA) protocol, or the Internet

Protocol-over-ATM (IPoA). Be sure to create the specific type of WAN interface your ISP

requires.

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 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. Delete the higher-level interface first, and

then delete the ATM interface.
