1.2 Features

High Speed Internet Access
The DSL RJ-11 (ADSL over POTS models) or RJ-45 (ADSL over ISDN models) connects to
your ADSL-enabled telephone line. The ZyXEL Device is compatible with the ADSL/
ADSL2/ADSL2+ standards. Maximum data rates attainable for each standard are shown in the
next table.

Table 1 ADSL Standards

DATA RATE STANDARD
ADSL
ADSL2
ADSL2+
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.
