The devices WAN-side interfaces are used to communication
via the DSL port. A WAN interface comprises two layers: a
lower-level ATM VC interface and a higher-level protocol
interface:
The ATM VC interface enables the device to communicate
using the Asynchronous Transfer Mode protocol. The ATM
protocol provides a common format for transmitting data over a
variety of hardware systems that make up the backbone of the
Internet. The 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.
After you have defined the ATM VC properties as described in
this topic, you can configure one of the higher level WAN
interfaces to enable communication with your ISP.
