Configure PPPoA Mode
Click the PPPoA button to use PPP over ATM connection mode. PPP is
a single link or multi-link interface between two packet switching devices,
such as a router or bridge. PPP is an efficient conduit for multiple
protocols such as IP and IPX, which are encapsulated across the
communications datalink. PPP over ATM is PPP frames that are carried
over ATM cells, which are the common transport and backbone used by
DSL service providers.
Your service provider, usually the telephone company or the ISP, will tell
you the values of VPI/VCI to use after you sign up the service. Your
service provider must also provide your User name, Password, and
Authentication protocol. To set the VPI/VCI parameters including adding,
modifying, and deleting, refer to "Set up VPI/VCI " in this manual.
