3. Quick Start
This chapter provides information on the Wizard Setup screens in the web
configurator.
3.1 Wizard Setup Introduction
Use the Wizard Setup screens to configure your system for Internet access settings
and fill in the fields with the information in the Internet Account Information table of
the Compact Guide or Read Me First. Your ISP may have already configured some of
the fields in the wizard screens for you.
3.1.1 Encapsulation
Be sure to use the encapsulation method required by your ISP. The ADSL Router
supports the following methods:
PPP over Ethernet (PPPoE RFC 2516): PPPoE provides access
control and billing functionality in a manner similar to dial-up services
using PPP. The ADSL Router bridges a PPP session over Ethernet (PPP
over Ethernet, RFC 2516) from your computer to an ATM PVC
(Permanent Virtual Circuit) which connects to ADSL Access Concentrator
where the PPP session terminates. One PVC can support any number of
PPP sessions from your LAN. For more information on PPPoE, see the
appendix.
PPP over ATM (PPPoA RFC2364): PPPoA stands for Point to Point
Protocol over ATM Adaptation Layer 5 (AAL5). It provides access control
and billing functionality in a manner similar to dial-up services using PPP.
The ADSL Router encapsulates the PPP session based on RFC1483 and
sends it through an ATM PVC (Permanent Virtual Circuit) to the Internet
Service Provider's (ISP) DSLAM (digital access multiplexer). Please refer
to RFC 2364 for more information on PPPoA. Refer to RFC 1661 for more
information on PPP.
RFC 1483 (Bridged and Routed Mode): RFC 1483 describes two
methods for Multiprotocol Encapsulation over ATM Adaptation Layer 5
(AAL5). The first method allows multiplexing of multiple protocols over a
single ATM virtual circuit (LLC-based multiplexing) and the second
method assumes that each protocol is carried over a separate ATM
virtual circuit (VC-based multiplexing). Please refer to the RFC for more
detailed information.
