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.
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.
