Preface

About Your SDSL Router

Congratulations on your purchase of the Prestige 681 SDSL Router.

Don’t forget to register your Prestige (fast, easy online registration at www.zyxel.com) for
free future product updates and information.

The Prestige 681 (P681) is an SDSL router used for Internet/LAN access via an SDSL line. The Prestige
681 supports multi-protocol routing for TCP/IP and Novell IPX, as well as transparent bridging for other
protocols. We will refer to the Prestige 681 as the P681 or simply the Prestige from now on.

The P681 SDSL router supports symmetrical multi-rate data transmission speeds from 144Kbps up to
2320Kbps. The actual rate depends on the copper category of your telephone wire, distance from the central
office and the type of SDSL service subscribed. See the sections below for more background information
on DSL and SDSL.

The P681 uses 2B1Q line code with echo cancellation for high data rate transmissions over a single twisted
telephone wire pair without being affected by bridge taps or mixed cable links. It also provides high
immunity from background noise.

The P681's 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.

Your Prestige is easy to install and to configure. All functions of the Prestige are software configurable via
the SMT (System Management Terminal) Interface.

About This User's Guide

This user's guide covers all operations of the Prestige 681 and shows you how to get the best out of the
multiple advanced features of your SDSL Router. It is designed to guide you through the correct
configuration of your Prestige 681 for various applications.

What is DSL?

DSL (Digital Subscriber Line) 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).

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 for SDSL
Maximum Transmission Distances). A SDSL connection is a point-to-point dedicated circuit, meaning that
the link is always up and there is no dialing required.

SDSL

SDSL (Symmetrical Digital Subscriber Line) is a symmetrical, bi-directional DSL service that operates on
one twisted-pair wire. It can provide data rates up to 2.3 Mbits/sec. Unlike traditional HDSL systems, which
use two twisted pair, SDSL reduces equipment and lease-line costs by providing the same service using
only one twisted pair and one modem at each end. SDSL is symmetric, which means you get the same
amount of bandwidth to and from the Internet. SDSL provides speeds up to 12 times faster than an ISDN
line and up to 50 times that of an analog modem connection at a fraction of the price of traditional dedicated
access services.

The "always-on" digital connection provides the stability and consistent high bandwidth so crucial to
today's online business community, allowing applications such as video conferencing, distance learning and
high-powered Web browsing to perform with peak efficiency. SDSL allows Webmasters to set-up a web
server, mail server and any other Internet service with increased bandwidth yet no additional charges.
Because SDSL is symmetric, it is ideal for businesses, especially if you host a web site. It provides you with
the high bandwidth required for uploading and downloading large data files and graphics. SDSL also gives
you the bandwidth you need to retrieve information from Internet POPs, Internet servers and private data
networks.

These are the main characteristics of SDSL:

•

Continuous
Connection

•

Dedicated
Bandwidth

xx What is DSL?

SDSL users are never disconnected. There is no wait for dialup, where
ISDN and regular analog modems often take half a minute to establish a
connection.

You select the line speed and it is “symmetric,” i.e., the same bandwidth in
both directions.

Low Maintenance

SDSL is scalable, offering customers a flexible upgrade path. You can
adjust your SDSL router when you decide you need a higher access speed.
This is an internal procedure; no site visit is necessary.

SDSL connectivity (unlike ISDN) requires no complex manual
configuration; SDSL equipment is simply "plug and play."

Comparisons with other high-speed technologies:

Cable Modems

With most Cable Modem systems, bandwidth is shared by a large number of clients. This means

•

that users may not achieve maximum transfer rates if the network is busy. The SDSL circuit is
point-to-point, which means that all bandwidth on the circuit is dedicated to a single client.

If your company needs fast Internet access then SDSL allows you to transfer data up to 3 times

•

ISDN

•

•

faster than with a cable modem

ISDN service is considerably slower than SDSL. ISDN equipment is generally limited to 128k
plus compression, which might give you speeds of up to 512 Kbps. SDSL gives you speeds of up

2.3Mbps.

ISDN does have the ability to travel over very large distances (across the country) while SDSL is
very distance limited.

.

T1

T1 is very expensive because it requires a high speed, noise conditioned phone line. SDSL works

•

over a simple "copper loop" and does not require an expensive conditioned line.

T1 delivers 1.5 Mbps in both directions over the line. SDSL delivers speeds of up to 2.3 Mbps in

•

both directions.

As its name implies, SDSL is a symmetric (equal upstream and downstream speeds) service that delivers
scalable, high-speed data communication speeds up to 2.3 Mbps. SDSL is the most reliable of the DSL
family members because it's based on proven technology that the telephone companies have been using for
years for their E1 service. Your Prestige integrates a high-speed 10/100Mbps auto-negotiating LAN
interface and one high-speed SDSL port into a single package. The Prestige is ideal for high-speed Internet
browsing and making LAN-to-LAN connections to remote networks.

1.2 Features of the Prestige 681

Your Prestige is packed with a number of features that give it the flexibility to provide a complete
networking solution for almost any user.

z Ease of Installation

.

Your Prestige is designed for quick, intuitive and easy installation. Physically, its compact size and
lightweight make it easy to position anywhere in your busy office.

z High Speed Scalability

One of the best features of SDSL service is its scalability. The P681 SDSL router supports symmetrical
multi-rate data transmission speeds from 144Kbps up to 2320Kbps. You can increase the capacity of the
Internet connection (within certain distance limitations ) without changing your ISP or purchasing new
equipment. SDSL’s high symmetrical speeds are ideal for applications like web hosting and
videoconferencing as well as the two-way data traffic needs of businesses.

z Frame Relay Support

Frame relay employs a simple form of packet switching that perfectly suits today’s powerful PCs,
workstations and servers. Its high throughput and reliability easily copes with bandwidth-hungry business
applications.

z 10/100M Fast Ethernet LAN Interface

The P681's 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.
