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 the
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

Preface

Congratulations on your purchase of the Prestige 791R G.SHDSL Router.

The Prestige is a high-performance router for Internet/LAN access via a telephone line. Your Prestige
supports multi-protocol routing for TCP/IP, as well as transparent bridging for other protocols.

The Prestige supports symmetrical multi-rate data transmission speeds 72 Kbps up to 2312 Kbps. The
actual rate depends on the copper category of your telephone wires, distance from the central office and the
type of DSL service you subscribe to. Its 10/100M auto-negotiating LAN interface enables fast data transfer
of either 10Mbps or 100Mbps in either half-duplex or full-duplex mode depending on your Ethernet
network. See the following section for more background information on DSL.

The Prestige uses TC-PAM line code with echo cancellation for high data rate transmissions over a single­twisted telephone wire pair without being affected by bridge taps or mixed cable links. It also provides high
immunity from background noise.

Your Prestige is easy to install and configure. All functions are configurable via the SMT (System
Management Terminal) and web configurator. Advanced users may configure the Prestige using CLI
(Command Line Interface) commands.

Please visit our web site at www.zyxel.com

xx Preface

Prestige 791R G.SHDSL Router

What is DSL?

DSL (Digital Subscriber Line) technology enhances the data capacity of the existing twisted-pair wire that
runs between the local telephone company switching offices and most homes and offices. While the wire
itself can handle higher frequencies, the telephone switching equipment is designed to cut off signals above
4,000 Hz to filter noise off the voice line, but now everybody is searching for ways to get more bandwidth to
improve access to the Web - hence DSL technologies.

There are actually seven types of DSL service, ranging in speeds from 16 Kbits/sec to 52 Mbits/sec. The
services are either symmetrical (traffic flows at the same speed in both directions), or asymmetrical (the
downstream capacity is higher than the upstream capacity). Asymmetrical services (ADSL) are suitable for
Internet users because more information is usually downloaded than uploaded. For example, a simple button
click in a web browser can start an extended download that includes graphics and text.

As data rates increase, the carrying distance decreases. That means that users who are beyond a certain
distance from the telephone company’s central office may not be able to obtain the higher speeds.

A DSL connection is a point-to-point dedicated circuit, meaning that the link is always up and there is no
dialing required.

What is G.SHDSL?

G.SHDSL (Single-pair High-speed Digital Subscriber Line) is a symmetrical, bi-directional DSL service that
operates on one twisted-pair wire and provides data rates up to 2.3 Mbits/sec. (The “G.” in “G.SHDSL” is
defined by the G.991.2 ITU (International Telecommunication Union) state-of-the-art industry standard).

Chapter 1

Getting to Know Your G.SHDSL Router

This chapter covers the key features and main applications of your Prestige.

The Prestige 791R Router can be used for high-speed LAN-to-LAN connections or Internet access through
a G.SHDSL connection over the telephone line. You can use your Prestige for either IP routing or bridging
depending on your ISP (Internet Service Provider) configuration.

1.1 Features of the Prestige

The following features make the Prestige a complete and the flexible networking solution for most users.

Scalability

One of the best features of G.SHDSL service is its scalability. You can increase the capacity of the Internet
connection (within certain distance limitations) without changing your ISP or purchasing new equipment.
G.SHDSL’s high symmetrical speeds are ideal for applications like web hosting and videoconferencing as
well as the two-way data traffic needs of businesses.

Symmetrical High Speed Internet Access

The Prestige 792H can support symmetrical transmission speeds of up to 2.3 Mbps. For NSP’s (Network
Service Provider) convenience, the Prestige also supports rate management depending on distance and
service charges.

The table below lists the transmission speeds available on the Prestige.

SUPPORTED TRANSMISSION SPEEDS

Min (Kbps) Max (Kbps)

SDSL

G.HDSL (G.991.2)

SNMP (Simple Network Management Protocol – versions 1 and 2)

SNMP, a member of the TCP/IP protocol suite, allows you to exchange management information between
network devices. Your Prestige supports SNMP agent functionality that allows a manager station to manage
and monitor the Prestige through the network.

Getting to Know Your G.SHDSL Router 1-1

72 136

200 2312

Prestige 791R G.SHDSL Router

SNMP is only available if TCP/IP is configured on your Prestige.

IP Multicast

Deliver IP packets to a specific group of hosts using IP multicast. IGMP (Internet Group Management
Protocol) is the protocol used to support multicast groups. The latest version is version 2 (see RFC 2236);
the Prestige supports both versions 1 and 2.

IP Alias

IP Alias allows you to partition a physical network into logical networks over the same Ethernet interface.
The Prestige supports three logical LAN interfaces via its single physical Ethernet interface with the
Prestige itself as the gateway for each LAN network.

IP Policy Routing

IP Policy Routing provides a mechanism to override the default routing behavior and alter packet
forwarding based on the policies defined by the network administrator.

10/100MB Auto-negotiation Ethernet/Fast Ethernet Interface

This auto-negotiation feature allows the Prestige to detect the speed of incoming transmissions and adjust
appropriately, providing a faster data transfer on the Ethernet network as required. It enables fast data
transfer of either 10 Mbps or 100 Mbps in either half-duplex or full-duplex mode depending on your
Ethernet network.

Protocols Supported

• TCP/IP (Transmission Control Protocol/Internet Protocol) network layer protocol.

• PPP (Point-to-Point Protocol) link layer protocol.

• SUA™ (Single User Account) and NAT (Network Address Translation).

PAP and CHAP Security

The Prestige supports PAP (Password Authentication Protocol) and CHAP (Challenge Handshake
Authentication Protocol). CHAP is more secure than PAP; however, PAP is available on more platforms.

DHCP Support

DHCP (Dynamic Host Configuration Protocol) allows the individual clients (computers) to obtain the
TCP/IP configuration at start-up from a centralized DHCP server. The Prestige has built-in DHCP server
capability, enabled by default, which means it can assign IP addresses, an IP default gateway and DNS
servers to other systems that support the DHCP client. The Prestige can now also act as a surrogate DHCP
server (DHCP Relay) where it relays IP address assignment from the actual real DHCP server to the clients.

1-2 Getting to Know Your G.SHDSL Router

Prestige 791R G.SHDSL Router

Encapsulation

The Prestige supports PPPoE, PPP over ATM (RFC-2364), Multiple Protocol over ATM (RFC-1483) and
ENET ENCAP.

SUA for Single-IP Address Internet Access

The Prestige’s SUA (Single User Account, equivalent to NAT) feature allows multiple user Internet access
for the cost of a single ISP account and allows multiple users on the LAN (Local Area Network) to access
the Internet concurrently. SUA supports popular Internet applications such as MS traceroute, CuSeeMe,
IRC, ICQ, RealAudio, VDOLive, Quake and PPTP. No extra configuration is needed to support these
applications. SUA address mapping can also be used for other LAN-to-LAN connections.

Universal Plug and Play (UPnP)

Using the standard TCP/IP protocol, the Prestige and other UPnP enabled devices can dynamically join a
network, obtain an IP address and convey its capabilities to other devices on the network.

Full Network Management

• Menu driven SMT (System Management Terminal) management

• SNMP manageable

• Web Configurator

Upgrade Firmware via LAN

In addition to the direct console port connection, the Prestige supports the up/downloading of firmware and
configuration file over the LAN.

Packet Filtering

Packet filtering blocks unwanted traffic from entering/leaving your network.

Ease of Installation

Your Prestige is designed for quick, easy and intuitive installation. Its compact size and light weight make it
easy to position anywhere in your busy office.

Multiple PVC (Permanent Virtual Circuits) Support

Your Prestige supports up to 12 PVC’s.

All-in-one Console and Auxiliary Port

Set the CON/AUX switch to the “CON” side when using the CON/AUX port as a regular console port for
local device configuration and management. Set this switch to the “AUX” side when using the CON/AUX
port as an auxiliary dial-up WAN connection.
