Chapter 1 Getting To Know Your ZyXEL Device
Note: If your ZyXEL Device does not support Annex M, the maximum ADSL2/2+ 
upstream data rate is 1.2 Mbps. ZyXEL Devices which work over ISDN do not 
support Annex M. 
The standard your ISP supports determines the maximum upstream and 
downstream speeds attainable. Actual speeds attained also depend on the 
distance from your ISP, line quality, etc.
Zero Configuration Internet Access
Once you connect and turn on the ZyXEL Device, it automatically detects the Internet 
connection settings (such as the VCI/VPI numbers and the encapsulation method) from the 
ISP and makes the necessary configuration changes. In cases where additional account 
information (such as an Internet account user name and password) is required or the ZyXEL 
Device cannot connect to the ISP, you will be redirected to web screen(s) for information input 
or troubleshooting.
Any IP
The Any IP feature allows a computer to access the Internet and the ZyXEL Device without 
changing the network settings (such as IP address and subnet mask) of the computer, when the 
IP addresses of the computer and the ZyXEL Device are not in the same subnet.
Traffic Redirect
Traffic redirect forwards WAN traffic to a backup gateway when the ZyXEL Device cannot 
connect to the Internet, thus acting as an auxiliary if your regular WAN connection fails.
Universal Plug and Play (UPnP)
Using the standard TCP/IP protocol, the ZyXEL Device and other UPnP enabled devices can 
dynamically join a network, obtain an IP address and convey its capabilities to other devices 
on the network.
PPPoE Support (RFC2516)
PPPoE (Point-to-Point Protocol over Ethernet) emulates a dial-up connection. It allows your 
ISP to use their existing network configuration with newer broadband technologies such as 
ADSL. The PPPoE driver on the ZyXEL Device is transparent to the computers on the LAN, 
which see only Ethernet and are not aware of PPPoE thus saving you from having to manage 
PPPoE clients on individual computers.
Network Address Translation (NAT)
Network Address Translation (NAT) allows the translation of an Internet protocol address 
used within one network (for example a private IP address used in a local network) to a 
different IP address known within another network (for example a public IP address used on 
the Internet).
