•This device may not cause harmful interference.
•This device must accept any interference received, including interference that may cause undesired
operations.
This equipment has been tested and found to comply with the limits for a Class B digital device pursuant to
Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful
interference in a commercial environment. This equipment generates, uses, and can radiate radio frequency
energy, and if not installed and used in accordance with the instructions, may cause harmful interference to

If this equipment does cause harmful interference to radio/television reception, which can be determined by
turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of
the following measures:
1. Reorient or relocate the receiving antenna.
2. Increase the separation between the equipment and the receiver.
3. Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.

iv Information for Canadian Users
Information for Canadian Users
The Industry Canada label identifies certified equipment. This certification means that the equipment meets
certain telecommunications network protective operation and safety requirements. The Industry Canada label
does not guarantee that the equipment will operate to a user's satisfaction.
Before installing this equipment, users should ensure that it is permissible to be connected to the facilities of
the local telecommunications company. The equipment must also be installed using an acceptable method of
connection. In some cases, the company's inside wiring associated with a single line individual service may
be extended by means of a certified connector assembly. The customer should be aware that compliance with
the above conditions may not prevent degradation of service in some situations.
Repairs to certified equipment should be made by an authorized Canadian maintenance facility designated by
the supplier. Any repairs or alterations made by the user to this equipment, or equipment malfunctions, may
give the telecommunications company cause to request the user to disconnect the equipment.
For their own protection, users should ensure that the electrical ground connections of the power utility,
telephone lines, and internal metallic water pipe system, if present, are connected together. This precaution
may be particularly important in rural areas.
Caution
Users should not attempt to make such connections themselves, but should contact the appropriate electrical
inspection authority, or electrician, as appropriate.
Note
This digital apparatus does not exceed the Class A limits for radio noise emissions from digital apparatus set
out in the radio interference regulations of Industry Canada.

Preface
About Your Gateway
Congratulations on your purchase of the Prestige 310 Broadband Sharing Gateway.
Don't forget to register your Prestige (fast, easy online registration at
www.zyxel.com) for free future product updates and information.
The Prestige 310 is a dual Ethernet broadband gateway integrated with network management features that
allows access to the Internet via cable/xDSL modem. It is designed for:
•Home offices and small businesses with cable and xDSL modem via Ethernet port as Internet access
media.
•Multiple office/department connections via access devices.
Your Prestige 310 is easy to install and to configure. The embedded web configurator is a convenient
platform-independent GUI (Graphical User Interface) that allows you easy access the Prestige's management
settings.
All functions of the Prestige 310 are also software configurable via the SMT (System Management Terminal)
interface. The SMT is a menu-driven interface that you can access from a terminal emulator through the
console port or over a Telnet connection.
About This User's Guide
This user's guide is designed to guide you through the SMT configuration of your Prestige 310 for its various
applications. There is also HTML help for the embedded web configurator. To access the web configurator,
follow the steps shown in the Accessing The Web Configurator section. Regardless of your particular
application, it is important that you follow the steps outlined in Chapters 1-2 to connect your Prestige to your
LAN. You can then refer to the appropriate chapters of the user's guide, depending on your applications.
