Introduction

Overview

Features

Thank you for purchasing the DOCSIS-compliant cable modem. This cable modem delivers
the highest performance in data over cable technology. Ideal for home and small business
users, this easy-to-use communication device offers reliable connectivity as well as remark­able data transfer rates--up to 43Mbps downstream and 10Mbps upstream, 100 times faster
than a 56K dial-up modem. Once the cable modem is powered up, you are online to enjoy
real-time 3D animation, video conferencing, and perform other data intensive operations.

• MCNS DOCSIS 1.0 compliant

• Support for 6MHz downstream and 200K-3200KHz upstream cable channel bandwidth

• Peak data transfer rates of 38Mbps (64QAM) and 42Mbps (256QAM)

• Auto detection of 64QAM or 256QAM

• Network management protocol support for SNMPv1/v2c and DOCSIS 1.0 MIBs

• Data Encryption Standard (DES) and Baseline Privacy Interface (BPI) compliant

• Easy installation and operation

• Self-diagnoses available through front panel LEDs

• Software upgradeable

Preparations

System
Requirements

Installing a
Network Card

Before connecting the cable modem to your PC, make sure your system is equipped with a
LAN controller and supports the TCP/IP protocol.

If your system does not have an embedded LAN controller, you must install a network
interface card as instructed below (assuming that you are using an Ethernet card under the
operating system of Windows 98):

1. Install the PCI-L101 card on your
motherboard.

2. Power up your PC and follow the Add
New Hardware Wizard’s instructions to

install the driver . When asked to restart
your computer at the end of the installa­tion, click Yes.

3. After restarting the system, right-click
My Computer on the desktop, select
Properties, click the Device Manager
tab, and then double-click Network
adapters to confirm that the Ethernet

driver is properly installed.

Preparations

Installing the
TCP/IP
Protocol

• Checking if TCP/IP is already installed

1. Click the Start button on the
desktop. In the Settings menu, select
Control Panel

Double-click the Network icon

• Adding TCP/IP in Network properties

1. Click Add.

.

.

2. Double-click Protocol.

2. In the list of installed network compo-

nents try to find the TCP/IP protocol. It
may be followed by the name of the
Ethernet controller. If you cannot locate
anything that begins with TCP/IP, install
it as described below.

3. Select Microsoft from the
manufacturers. In the list
of network protocols
browse to TCP/IP and
then double-click it.

1. DC +5V/2A Power Input Jack

The provided power adapter converts AC power to DC power for use with this jack. Power
supplied through this jack will supply power to the cable modem.

2. RF Connector

The connector may be located right next to the power input jack or the serial port. The F­Type female connector allows cable data communication between the cable modem and

the cable service provider through a coaxial cable.

3. Serial Port

The 9-pin D-sub serial port supports the RS-232 terminal interface for advanced cable
modem management.

4. Reset Switch

The reset button, when pressed, resets the cable modem without the need to unplug the
power cord.

5. USB Port (optional)

The optional USB port allows the modem to be connected to your computer through the
USB interface.

6. 10/100-BaseT LAN Port

The LAN port supports 10Base-T or 100Base-TX networks. This port allows your PC or
Ethernet hub to be connected to the cable modem through a CAT .5 twisted pair LAN cable.

Installing the
Cable Modem

Take the following steps to accomplish the installation procedure:

1. Connect the cable TV coaxial cable to the input connector of a signal splitter.

2. Connect a coaxial cable from one of the output connectors on the splitter to the input

connector of your TV set.

3. Use another coaxial cable to connect the other output connector on the splitter and the
RF connector on the rear panel of the cable modem.

4. Connect the LAN cable from the LAN port on your computer to the LAN port on the
rear panel of the cable modem.

5. Connect the AC power adapter to the DC +5V/2A input jack on the rear panel of the
cable modem. Plug in the AC power adapter to an electrical outlet.

NOTE: If you are not using a television on the cable line, you may skip steps 1 to 3 and
connect the cable TV coaxial cable directly to the RF connector on the rear panel of the cable
modem.

Using the Cable Modem

Powering Up

Multiple Client
Configuration

When all connections have been properly made and the power is ON, the cable modem will
automatically start the self-test and search for the active cable channel provided by your
cable operator. Now you are all set and ready to surf the internet at a marvelous speed!

The cable modem supports up to 15 pieces of consumer premises equipment. If you can
obtain multiple IP addresses from your cable operator, you can hook up as many comput­ers to the cable modem as the number of the IP addresses, using a hub inbetween (as
shown below). Each connected client PC will then be assigned one dynamic IP address by
the cable operator.

This DOCSIS Cable Modem has been tested and found to comply with the limits for a class B
personal computer and peripherals, pursuant to Part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference in a residential
installation. This equipment generates, uses and can radiate radio frequency energy and, if
not installed and used in accordance with the instructions, may cause harmful interference to
radio communications. However, there is no guarantee that interference will not occur in a
particular installation. If this unit does cause harmful interference to radio or television
reception, which can be determined by turning the unit off and on, the user is encouraged to
try to correct the interference by one or more of the following measures:

• Reorient or relocate the receiving antenna.

• Increase the separation between the equipment and receiver.

• Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.

This product meets all safety requirements per UL-1950 standard.

This certificate of conformity is based on an evaluation of the cable modem that is in compli­ance with the Low Voltage Directive 73/23/EEC and the Amendment Directive 93/68/EEC.
