ZyXEL Communications Corporation P873HNUP51B Manuel D’Utilisation

P-873HNUP-51B User’s Guide

This chapter describes how to configure WAN settings from the Broadband screen. Use this screen 
to configure your ZyXEL Device for Internet access. 

If the DSLAM of your ISP supports DSL bonding, you can connect the two DSL ports on the ZyXEL 
Device to two separate telephone jacks and enable the bonding feature in the DSL screen. The 
bonding feature provides increased throughput at longer distances.

A WAN (Wide Area Network) connection is an outside connection to another network or the 
Internet. It connects your private networks (such as a LAN (Local Area Network) and other 
networks, so that a computer in one location can communicate with computers in other locations.

Figure 16   LAN and WAN

Encapsulation is used to include data from an upper layer protocol into a lower layer protocol. To set 
up a WAN connection to the Internet, you need to use the same encapsulation method used by your 
ISP (Internet Service Provider). If your ISP offers a dial-up Internet connection using PPPoE (PPP 
over Ethernet) or PPPoA, they should also provide a username and password (and service name) 
for user authentication.
