Preface

About Your SDSL Internet Access 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 Internet Access Router. It is designed to guide you through the

Preface

Prestige 681 SDSL Router

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 (see Table
3-2 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

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.

• Investment

Protection

• 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
faster than with a cable modem.

ISDN

• 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.

Prestige 681 SDSL Router

25-pin console cable supplied) to the console port of the Prestige and the 25-pin end to a serial port (COM1,
COM2 or other COM port) of your workstation. You can use an extension RS-232 cable if the enclosed
one is too short.

Step 4. Connecting a Workstation to the Prestige 10/100M LAN port

Ethernet 10Base-T networks use Shielded Twisted Pair (STP) cable with RJ-45 connectors that look like a
bigger telephone plug with 8 pins. Use the crossover cable (red tag) to connect your Prestige 681 to a
computer directly. Use straight through Ethernet cable (white tag) to connect to an external hub and then
connect one end of a straight through Ethernet cable (white tag) from the hub to the NIC on the workstation.

Step 5. Connecting the Power Adapter to your Prestige
Connect the power adapter to the port labeled POWER on the rear panel of your Prestige.

2.3 Additional Installation Requirements

before you can install and use your Prestige. These requirements include:

l A computer with Ethernet 10Base-T/100Base-T NIC (Network Interface Card).
l A computer equipped with communications software (for example, Hyper Terminal in Win95)

configured to the following parameters:

Ø VT100 terminal emulation.
Ø 9600 Baud rate.
Ø No parity, 8 Data bits, 1 Stop bit.

Ø Flow Control set to None

After the Prestige has been successfully connected to your network, you can make future changes to the
configuration through telnet application.

2.4 Housing

Your Prestige's ventilated housing has clip-out legs that fit snugly into grooves, enabling compact, sturdy
stacking with airflow between routers. You should not stack more than 4 routers for maximum stability.

2.5 Important Safety Instructions

1. Be sure to read and follow all warning notices and instructions.

Hardware Installation & Setup

2-3

Prestige 681 SDSL Router

2. The maximum recommended ambient temperature for the Prestige is 40º(104º). Care must be taken to

allow sufficient air circulation or space between units when the Prestige is installed inside a closed rack
assembly. The operating ambient temperature of the rack environment might be greater than room
temperature.

3. Installation in a rack without sufficient airflow can be unsafe.

4. Racks should safely support the combined weight of all equipment.

5. The connections and equipment that supply power to the Prestige should be capable of operating safely

with the maximum power requirements of the Prestige. In the event of a power overload, the supply
circuits and supply wiring should not become hazardous. The input rating of the Prestige is printed on
the nameplate.

6. The AC adapter must plug in to the right supply voltage, i.e. 120VAC adapter for North America and

230VAC adapter for Europe. Make sure that the supplied AC voltage is correct and stable. If the input
AC voltage is over 10% lower than the standard may cause the Prestige to malfunction.

7. Installation in restricted access areas must comply with Articles 110-16, 110-17, and 110-18 of the

National Electrical Code, ANSI/NFPA 70.

8. Do not allow anything to rest on the power cord of the AC adapter, and do not locate the product where

anyone can walk on the power cord.

9. Do not service the product by yourself. Opening or removing covers can expose you to dangerous high

voltage points or other risks. Refer all servicing to qualified service personnel.

10. Generally, when installed after the final configuration, the product must comply with the applicable

safety standards and regulatory requirements of the country in which it is installed. If necessary,
consult the appropriate regulatory agencies and inspection authorities to ensure compliance.

11. A rare condition can create a voltage potential between the earth grounds of two or more buildings. If

products installed in separate building are interconnected, the voltage potential can cause a hazardous
condition. Consult a qualified electrical consultant to determine whether or not this phenomenon exists
and, if necessary, implement corrective action before interconnecting the products. If the equipment is
to be used with telecommunications circuit, take the following precautions:

• Never install telephone wiring during a lightning storm.

• Never install telephone jacks in wet location unless the jack is specially designed for wet location.

• Never touch uninsulated telephone wires or terminals unless the telephone line has been

disconnected at the network interface.

• Use caution when installing or modifying telephone lines (other than a cordless telephone) during

an electrical storm. There is a remote risk of electric shock from lightning.
