Prestige 941 Cable Router

Getting to Know Your Prestige 1-1

Chapter 1

Getting to Know Your Cable Router

This chapter provides functional overviews, key features, applications and product specifications of your
Prestige Cable Router.

1.1 Overview of the Prestige 941 Cable Router

The Prestige is a high bandwidth Internet access Cable Router that connects your LAN to the Internet
using the hybrid fiber coaxial (HFC) cable; the same cable that brings television into a cable television
(CATV) subscriber’s home. With the Prestige Cable Router, a computer can be connected to the HFC
cable network for high-speed access to the Internet. It is ideal for cable users with more than one computer
and is an excellent alternative to the more expensive leased lines.

Prestige cable routers are based on the Multimedia Cable Network System (MCNS) Data Over Cable
Service Interface Specification (DOCSIS) standards specifications. MCNS is a consortium of cable
television companies whose goal is to create standards for interoperable data-over-cable systems.

The Prestige operates with one external 9V DC-input power supply.

1.2 Bridge and Router

According to DOCSIS specification, a cable modem is basically a bridge device. It can be configured to
serve specific CPEs by provisioning their MAC addresses. Only traffic to/from these CPEs will be
forwarded. The others will be filtered. It can also be configured to serve specific numbers of CPEs.
However, these services are provided by your cable operator. They have to setup one account for each CPE.

For most Internet users, they have only one access account. If they have two computers' at home and want
to share this account for two or more users, they have to add another Internet sharing device, like a router.

Prestige 941 Cable Router

1-2 Getting to Know Your Prestige

The Prestige Cable Router can be configured as either a bridge or router. In router mode, it is equivalent to
a cable modem plus a router. This is very suitable for Internet sharing.

1.3 Key Features of the Prestige 941 Cable Router

The following are the key features of the Prestige 941 Cable Router:

• DOCSIS compliant cable modem

Provides interoperability with other DOCSIS compliant cable modems and cable headend equipment.

• Support for both Bridging and Routing operation modes

With both Bridging and Routing operation modes, the Prestige is highly suitable for both residential and
SOHO applications.

• Peak downstream signaling rates of 43 Mbps and upstream signaling rates of 10 Mbps

Access the Internet with high performance network capability.

• IP routing, TCP, ICMP, ARP, TFTP, RIP1, RIP2 using the ZyNOS software

Improves network performance through containment of broadcast messages and improves security through
address filtering of IP packets and support for unicast, broadcast and multicast IP packets.

• SUA/NAT for single-IP-address Internet access

The SUA (Single User Account) feature allows multiple users to share a single ISP account.
IP routing combines port-level multiplexed NAT (Network Address Translation) to provide ease of

configuration in SOHO networks and to provide conservation of IP addresses and dynamic allocation of
address.

• Auto-negotiating 10/100 Mbps Ethernet

The LAN interface automatically detects if it is on a 10 Mbps or a 100 Mbps Ethernet.

• 56-bit DES Baseline Privacy

• MAC address, IP address and TCP/UDP ports filtering

• Packet Filter

Prestige 941 Cable Router

Getting to Know Your Prestige 1-3

The Packet Filter blocks unwanted traffic from entering/leaving your network.

• DHCP Server

The Prestige's DHCP (Dynamic Host Configuration Protocol) server capability allows you to automatically
assign TCP/IP settings to a workstation on your LAN.

• DHCP Client

The Prestige’s DHCP client capability allows it to get its IP address from the ISP automatically.

• Full Network Management

This feature allows you to access SMT (System Management Terminal) through the console port or telnet
connection.

• RoadRunner Support

In addition to standard cable modem services, the Prestige supports Time Warner’s RoadRunner Service.

• Logging and Tracing

Built-in message logging and packet tracing.

• UNIX Syslog Support

• Software Remotely Upgradeable

The software and configuration information is downloadable from the cable headend to the cable router.
This eliminates the need for a cable technician's visit to install software upgrades.

• Built-in Remote Diagnostic Features

Perform device configuration and troubleshooting via a direct terminal connection or by boot-up and
CMTS-initiated diagnostics, eliminating visit by a technician.

1.4 Internet Access Applications for Prestige 941

This section shows you the possible applications for your Prestige 941.
With built-in routing capability, the Prestige SUA/NAT function allows users to connect multiple

workstations to the Internet with a single IP address via HFC network. Your Prestige supports the TCP/IP

protocol that the Internet uses exclusively. Typical Internet access applications in a home and business
environment are shown next.

Figure 1-1 Home Environment

Figure 1-2 Business Environment

For Internet access applications, the highlights of the Prestige’s distinguished features are described as
follows:

• High Speed Access to the Internet

Downstream (receive) signal rate of up to 43 Mbps, and upstream (send) signal rate of up to 10 Mbps
(Please see NOTE).

Prestige 941 Cable Router

Getting to Know Your Prestige 1-5

• Support for both Bridging and Routing operation modes

The Prestige is highly suitable for both residential and SOHO applications as it supports both bridging and
routing modes.

Internet Single User Account

For a SOHO (Small Office/Home Office) environment, your Prestige offers a Single User Account (SUA)
feature that allows multiple users on the LAN (Local Area Network) to access the Internet concurrently at
the cost of a single user.

• Multicast Messages

Multiple users can receive important information at the same time.

• User Data Privacy

Upstream and downstream data is encrypted to provide data privacy protection.

• 10/100 Mbps Ethernet Interface

10/100 Mbps Ethernet interface provides high speed and flexible LAN interface.

• Software Remotely Upgradeable

Software and configuration information is downloadable from the headend CMTS to the cable router for
future software upgrade. Your cable operator will help you in future software upgrades.

NOTE: DOCSIS cable systems are capable of providing signaling rate of up to 43

Mbps and 10 Mbps for downstream and upstream respectively. This bandwidth

however, is shared by several subscribers because there are very few

computers today that can connect to a network at such high speeds. Hence,

typical connection speeds are 5 Mbps downstream and 1 Mbps upstream.

2.2 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:

1. You must have a network interface card installed on your computer and configure the TCP/IP protocol
stack properly. In addition, please configure your computer as a DHCP client.

2. A computer equipped with communications software configured to the following parameters:

• VT100 terminal emulation.

• 9600 Baud.

• No parity, 8 Data bits, 1 Stop bit.

• Flow Control set to None.

3. An ISP account. Before installing your cable router, you need to establish an Internet access account
with your local cable operator. They might ask for your cable router’s MAC address and model number.
Please locate the MAC address at the bottom of your Prestige 941.

NOTE: HFC MAC address can be found on the bar code sticker. Use the HFC MAC

address when registering with your cable company.

After the Prestige is properly set up, you can make future changes to the configuration through telnet
connections.

2.3 Initializing the Cable Modem

This section outlines how to connect your Prestige 941 to the LAN and the cable network.

Step 1. Preparing the CATV Coaxial Cable Connection

Locate the coaxial cable at the installation site and move the cable end, or install a two-way splitter as
necessary to provide a connection near the Prestige 941 cable modem location.

Step 2. Connecting the Prestige to the Cable System

Connect the Prestige to the cable port using an F-type connector. (If the quality or general condition of the
coaxial cable at the installation site is in question, we recommended that you replace the coaxial cable). The
cable port on the Prestige is labeled "CABLE”.

Step 3. Connecting Ethernet Cables to the Prestige 941

If you do not have an Ethernet interface card (NIC) in your computer, please install one.
If you have only one computer, you can connect the Prestige to the computer directly without a hub. For a
single computer, connect the 10/100M LAN port on the Prestige to the Network Adapter on the computer
using a straight-through Ethernet cable.
If you have more than one computer, you must use an external hub. Connect the 10/100M LAN port on the
Prestige to a port on the hub using a cross-over Ethernet cable. If your Ethernet hub provides cascade (also
called uplink) port, you can connect the Prestige to that port by using a straight Ethernet cable.

Step 4. Connecting the Prestige 941 to the Computer(s)

For a single computer, locate an available end of the Ethernet cable that you just connected to the Prestige
and connect this end to the Ethernet port on the computer.
For more than one computer, connect your computers to the hub using other straight Ethernet cable.

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.

Step 6. Cable Router Initialization

The Prestige cable router is powered on whenever you connect the power adapter to the power outlet. It will
initialize the system and start to connect with headEnd CMTS. When the CABLE LED shines steadily, the
Prestige is ready to handle data traffic. The first initialization process might take several minutes because it
will scan for the proper downstream and upstream channels. When the cable modem is ready, it will
memorize the channel attributes. If you power cycle the cable modem, the next connection process will be
faster.

Generally, your cable company will configure your Prestige for you. You do not have to do any configuration.

Step 7. Connecting the Console Port

For Internet sharing, you have to configure your Prestige in Router mode. You need to use a terminal
emulator software on a workstation and connect it to the Prestige through the console port. Connect the 9-pin
(smaller) end of the console cable to the console port of the Prestige and the other 9-pin or 25-pin (bigger)
end to a serial port (COM1, COM2 or other COM port) of your workstation. You can use an extension RS­232C cable if the enclosed one is too short.

For users using a DOS version terminal emulator, you may need to configure your communication
parameters as follows:

VT100 terminal emulation
9600 Baud rate

Hardware Installation and Initial Setup 2-5

No parity, 8 Data bits, 1 Stop bit
No flow control

After the initial setup, you can modify the configuration remotely through telnet connections.

NOTE: When using the Prestige 941 in Router mode, use the default (static) IP

address of 192.168.1.1 to telnet from your LAN PC to your Prestige 941.

2.4 Network Configuration of Your Computer

You must have a network interface card installed on your computer and configure the TCP/IP protocol stack
properly. For Windows® 95/98/NT, please configure your computer as a DHCP client.

For Windows® 95/98, you can use the following command to verify the TCP/IP configuration.

Winipcfg

For Windows® NT, you can use the following command.

Ipconfig

2.5 Router Configuration

While your Prestige operates in Router mode, you have to further configure it through the console port.
In router mode, you do not need to ask your cable company for a special configuration. The Prestige can act

as a DHCP client to acquire an IP address from the headend. Besides, it can act as a DHCP server at the LAN
port and assign an IP address to your computers on the LAN subnet. What you have to do is to configure the
LAN port with the proper IP address and netmask. If you already have a DHCP server on your LAN subnet,
you can disable the DHCP server in the Prestige but you have to assign an IP address/ netmask for the LAN
port.

For more details, please refer to Chapter 3 – Internet Access.

2-6 Hardware Installation and Initial Setup

2.6 Power On Your Prestige

At this point, you should have connected the console port, the LAN port, the cable port and the power port to
the appropriate devices or lines. Plug the power adapter into a wall outlet.

When connected and powered on, the cable router executes an automatic installation procedure:

1. Scans and locks on to the service provider’s downstream frequency.

2. Obtains timing, signal, power level, authentication, addressing, and other operational parameters from the
CATV headend.

3. Downloads its configuration file and is then operational.

During the initialization, the LEDs on the cable router turns on:

1. The Power LED should be ON.

2. The CABLE LED flashes on a 2 seconds on/off cyclic duration while scanning downstream channel and
then on a 1 second on/off cyclic duration when it has locked on to the downstream channel and is
communicating with headend CMTS. Once the cable connection is complete, it will stay ON.

3. The DATA LED flashes when the cable downstream, cable upstream, or LAN is receiving and
transmitting data. It is OFF when the connection is idle.

4. The LAN10M LED or LAN100M LED (depending on the Ethernet speed connection) will be ON if
Ethernet link is successful and flashing while sending/receiving.
