Chapter 1 Introducing the ZyXEL Device

•Back up the configuration (and make sure you know how to restore it). Restoring an earlier working configuration may be useful if the device becomes unstable or even crashes. If you forget your password, you will have to reset the ZyXEL Device to its factory default settings. If you backed up an earlier configuration file, you would not have to totally re-configure the ZyXEL Device. You could simply restore your last configuration.

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.

Triple Play Service

The ZyXEL Device is a Triple Play Gateway, capable of simultaneously transferring data, voice and video over the Internet. The Gateway possesses advanced Quality of Service (QoS) features to provide a high standard of Triple Play delivery.

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.
