Preface

About Your ADSL Internet Access Router

Congratulations on your purchase of the Prestige 641 ADSL Internet Access Router.
The Prestige 641 (P641) is an ADSL router used for Internet/LAN access via an ADSL line. The Prestige

641 supports multi-protocol routing for TCP/IP and Novell IPX, as well as transparent bridging for other
protocols. We will refer to the Prestige 641 as the P641 or simply the Prestige from now on.

The P641 can run upstream maximum transmission rates of 640Kbps and downstream maximum
transmission rates of 8Mbps. The actual rate depends on the copper category of your telephone wire,
distance from the central office and the type of ADSL service subscribed. See the sections below for more
background information on DSL and ADSL.

The P641'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 aspects of the Prestige 641 operations and shows you how to get the best out of
the multiple advanced features of your ADSL Internet Access Router. This manual is designed to guide you
through the correct configuration of your Prestige 641 for various applications.

Syntax Conventions

• “Enter” means for you to type one or more characters and press the carriage return. “Select” or

“Choose” means for you to select one from the predefined choices.

• The SMT menu titles and labels are in Bold Times font. The choices of a menu item are in Bold
Arial font. A single keystroke is in Arial font and enclosed in square brackets, for instance, [ENTER]

means the Enter, or carriage return, key; [ESC] means the Escape key.

• For brevity’s sake, we will use “e.g.” as a shorthand for “for instance”, and “i.e.” as a shorthand for
“that is” or “in other words” throughout this manual

Prestige 641 ADSL Internet Access 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). 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 ADSL?

It is an asymmetrical technology, meaning that the downstream data rate is much higher than the upstream
data rate. As mentioned, this works well for a typical Internet session in which more information is
downloaded, e.g., from Web servers, than is uploaded. ADSL operates in a frequency range that is above
the frequency range of voice services, so the two systems can operate over the same cable.

1.3 Applications for the Prestige 641

1.3.1 Internet Access`

The Prestige is the ideal high-speed Internet access solution. Your Prestige supports the TCP/IP protocol,
which the Internet uses exclusively. It is compatible with all major ADSL DSLAM (Digital Subscriber
Line Access Multiplexer) providers. A DSLAM is a rack of ADSL line cards with data multiplexed into a
backbone network interface/connection (e.g., T1, OC3, DS3, ATM or Frame Relay). Think of it as the
equivalent of a modem rack for ADSL. A typical Internet Access application is shown below.

Step 1. Connecting the ADSL Line

Connect the Prestige directly to the wall jack using the included ADSL cable. Connect the micro filter(s)
(supplied – see Figure 2-4 Connecting the Microfilter) between the wall jack and your telephone(s). The
micro filters act as low pass filters (voice transmission takes place in the 0 to 4KHz bandwidth).

Step 2. 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 641 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 3. Connecting the Power Adapterto your Prestige

Connect the power adapter to the port labeled POWER on the rear panel of your Prestige.
Step 4. Connecting the Console Port

For the initial configuration of your Prestige, you need to use terminal emulator software on a workstation
and connect it to the Prestige through the console portConnect the 9-pin (smaller) end of the console cable
to the console port of the Prestige and the 25-pin (bigger) 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.

2.3 Additional Installation Requirements

In addition to the contents of your package, there are other hardware and software requirements you need
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.

2-2 Hardware Installation & Setup

Prestige 641 ADSL Internet Access Router

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

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 Telephone Microfilters

Telephone voice transmissions take place in the lower frequency range, 0 - 4KHz, while ADSL
transmissions take place in the higher bandwidth range, above 4KHz. ZyXEL provides a microfilter that
acts as a low-pass filter for your telephone to ensure that ADSL transmissions do not interfere with your
telephone voice transmissions. Connect a phone cable from the wall jack to the wall side of the microfilter,
and then connect the phone side of the microfilter to your telephone as shown.

2.9 Resetting the Prestige

If you have forgotten your password or for some reason cannot access the SMT menu you will need to
reinstall the configuration file. Uploading the configuration file replaces the current configuration file with
the default configuration file, you will lose all configurations that you had before and the speed of the
console port will be reset to the default of 9600 bps with 8 data bit, no parity and 1 stop bit (8n1). The
password will be reset to the default of 1234, also.

Turn off the Prestige and begin a Telnet session with the default console port settings. Turn on the Prestige
again. You should see the following screen. When you see the message " Press Any key to enter Debug
Mode within 3 seconds", press any key to enter debug mode. You should already have downloaded the
"romfile.zip" file from the Internet and unzipped it. See section 10.5 Restore Configuration on page 10-9 for
more information.

2.9.1 Filename conventions

The configuration filename is the router model name with a rom extension, e.g., p641.rom. The ZyNOS
firmware filename is the router model name with a bin extension, e.g., p641.bin. Rename the latter filename
to “ras” when uploading to the Prestige. See section 10.6 Firmware Update on page 10-9 for more
information.
