ZyXEL Communications P-660RU-T V2 사용자 설명서

P-660RU-T v2 User’s Guide

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

Use the Wizard Setup screens to configure your system for Internet access with the  
information provided by your ISP. Your ISP may have already configured some of the fields 
in the wizard screens for you.

Be sure to use the encapsulation method required by your ISP. The ZyXEL Device supports 
the following methods.

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.

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

PPPoA stands for Point to Point Protocol over ATM Adaptation Layer 5 (AAL5). A PPPoA 
connection functions like a dial-up Internet connection. The ZyXEL Device 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 Subscriber Line (DSL) 
Access Multiplexer). Please refer to RFC 2364 for more information on PPPoA. Refer to RFC 
1661 for more information on PPP.
