Preface

About Your Prestige

Congratulations on your purchase of the Prestige 782M G.SHDSL Bridge.

The Prestige is a high-performance modem for Internet/LAN access via a telephone line. Your Prestige

supports multi-protocol routing for TCP/IP and transparent bridging for other protocols.

The Prestige supports symmetrical multi-rate data transmission speeds from 72Kbps up to 2320Kbps. The

actual rate depends on the copper category of your telephone wires, distance from the central office and the

type of xDSL 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 xDSL.

Register your Prestige online at www.zyxel.com for free future product updates and

information.

Your Prestige is easy to install and configure. All functions of the Prestige are software configurable via the

SMT (System Management Terminal). Advanced users may configure the Prestige using CLI (Command

Line Interface) commands.

xvi Preface

P782M G.SHDSL Bridge

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.

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.

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.

The Benefits of G.SHDSL:

• Continuous Connection

You are always online.

• Dedicated Bandwidth

• Investment Protection

• Low Maintenance

• Distance Capabilities

Line speed is “symmetric,” i.e., the same bandwidth in both directions.

Scalability. Offers a flexible upgrade path. You can choose a higher
access speed yourself - no site visit is necessary.

Connectivity requires no complex manual configuration.

G.SHDSL achieves 20% better loop-reach than older versions of
symmetric DSL. (Loop reach defines speed that can be attained at
various distances).

2.2 Rear Panel and Connections of the Prestige 782

The following figure shows the rear panel of your Prestige.

Figure 2-2 Prestige 782 Rear Panel and Connections

2.2.1 xDSL Port

Connect the Prestige (port labeled xDSL) to the telephone jack using the RJ-11 cable (supplied).

2.2.2 Console Port

For the initial configuration of your Prestige, you need to use terminal emulator software on a computer and
connect it to the Prestige through the console port. Connect the 9-pin end of the console cable to the console
port of the Prestige and the other 9-pin end to a serial port (COM1, COM2 or other COM port) of your
computer. You can use an extension RS-232 cable if the enclosed one is too short.

2-2 Hardware Installation and Initial Setup

P782M G.SHDSL Bridge

2.2.3 LAN 10/100M Port

Ethernet 10Base-T/100Base-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 to connect your Prestige to a
computer directly or use a straight-through Ethernet cable to connect to an external hub, then connect one
end of the straight-through cable from the hub to the NIC on the computer.

When the Prestige is on and properly connected to a computer or a hub, the

corresponding LAN LED on the front panel turns on.

2.2.4 Power Port

Connect the power adapter to the port labeled POWER on the rear panel of your Prestige.

To avoid damage to the Prestige, make sure you use the correct power adapter.

Refer to the Power Adapter Specification Appendix for this information.

2.3 Additional Installation Requirements

• An Ethernet 10/100Base-T NIC (Network Interface Card).

• Communications software configured as follows:

 VT100 terminal emulation

 9600 baud

 parity set to none, 8 data bits, 1 stop bit

 flow control set to none

2.4 Turning On Your Prestige

At this point, you should have connected the xDSL, LAN 10/100M, console and power ports to the
appropriate devices. Make sure the power adapter is plugged into an appropriate power source and the
power switch (located on the back of your Prestige) is “on” (or pressed).

2.5 Configuring Your Prestige For Internet Access

Configure your Prestige for Internet access using:

 SMT (System Management Terminal). Access the SMT via:

o LAN or WAN using Telnet

Hardware Installation and Initial Setup

P782M G.SHDSL Bridge

If, after logging on, there is no activity for longer than 5 minutes, your Prestige

will automatically log you out and display a blank screen. Press [ENTER] to bring

up the login screen again.

2.6 Resetting the Prestige

If you forget your password or cannot access the Prestige, you will need to reload the factory-default
configuration file. Uploading the configuration file replaces the current configuration file with the factory­default configuration file. This means that you will lose all configurations that you had previously and the
speed of the console port will be reset to the default of 9600bps with 8 data bit, no parity, one stop bit and
flow control set to none. The password will be reset to “1234” and the LAN IP address to 192.168.1.1also.

To obtain the default configuration file, download it from the ZyXEL FTP site, unzip it and save it in a
folder. Turn the Prestige off and then on to begin a session. When you turn on the Prestige again you will
see the initial screen. When you see the message “Press any key to enter Debug Mode within 3 seconds”
press any key to enter debug mode.

To upload the configuration file, do the following:

1. Type atlc after the Enter Debug Mode message.

2. Wait for the Starting XMODEM upload message before activating XMODEM upload on your
terminal.

3. After a successful firmware upload, type atgo to restart the Prestige.

The Prestige is now reinitialized with a default configuration file including the default password of “1234”.

2.6.1 Methods of Restoring Factory-Defaults

You can erase the current configuration and restore factory defaults by uploading the default configuration
file via the console port as described above. See later in this User’s Guide for more information on how to
transfer the configuration file to your Prestige using the SMT menus.
