Wizard Setup for Internet Access

This chapter provides information on the Wizard Setup screens for Internet access in the web

3.1 Introduction

Use the Wizard Setup screens to configure your system for Internet access with the
information (provided by your ISP) that you fill in the Internet Account Information table in
the Quick Start Guide. 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 Prestige supports the
following methods.

3.1.1.1 ENET ENCAP

The MAC Encapsulated Routing Link Protocol (ENET ENCAP) is only implemented with the
IP network protocol. IP packets are routed between the Ethernet interface and the WAN
interface and then formatted so that they can be understood in a bridged environment. For
instance, it encapsulates routed Ethernet frames into bridged ATM cells. ENET ENCAP
requires that you specify a gateway IP address in the ENET ENCAP Gateway field in the
second wizard screen. You can get this information from your ISP.

3.1.1.2 PPP over Ethernet

PPPoE provides access control and billing functionality in a manner similar to dial-up services
using PPP. The Prestige 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 appendices.

3.1.1.3 PPPoA

PPPoA stands for Point to Point Protocol over ATM Adaptation Layer 5 (AAL5). A PPPoA
connection functions like a dial-up Internet connection. The Prestige 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.
