Relationship among the Devices
This illustration shows a cable company that offers Euro-DOCSIS- and Euro-PacketCable-compliant
voice/data services.
What the Modem Does
The Wireless Voice Gateway provides high-speed Internet access as well as cost-effective, toll-quality
telephone voice and fax/modem services over residential, commercial, and education subscribers on
public and private networks via an existing CATV infrastructure. It can inter-operate with the
Euro-PacketCable compliant head-end equipment and provide the IP-based voice communications. The
IP traffic can transfer between the Wireless Voice Gateway and Euro-DOCSIS compliant head-end
equipment. The data security secures upstream and downstream communications.

What the Modem Needs to Do Its Job
ꢀ
The Right Cable Company: Make sure your local cable company provides data services that
use cable TV industry-standard Euro-DOCSIS compliant and Euro-PacketCable compliant
technology.
ꢀ
The Internet/Telephony Service Provider (ISP/TSP): Your cable company provides you
access to an Internet Service Provider (ISP) and Telephony Service Provider (TSP). The ISP is
your gateway to the Internet and provides you with a pipeline to access Internet content on the
World Wide Web (WWW). The TSP provides you with telephony access to other modems or
other telephony services over the Public Switched Telephone Network (PSTN).
Check with your cable company to make sure you have everything you need to begin; they’ll know if
you need to install special software or re-configure your computer to make your cable internet service
work for you.
Contact Your Local Cable Company
You will need to contact your cable company to establish an Internet account before you can use your
gateway. You should have the following information ready (which you will find on the sticker on the
gateway):
•
•
•

The serial number
The model number
The Cable Modem (CM) Media Access Control (MAC) address
The Terminal Adapter (EMTA) MAC address
Security information: Service Set IDentifier (SSID), Encryption key / passphrase (WPA2-PSK
by default), channel number. Default values are indicated underneath the modem on the sticker.
Please verify the following with the cable company
ꢀ The cable service to your home supports Euro-DOCSIS compliant two-way modem access.
ꢀ Your internet account has been set up. (The Media Terminal Adapter will provide data service if
the cable account is set up but no telephony service is available.)
ꢀ You have a cable outlet near your PC and it is ready for Cable Modem service.

Forcing end user to change the password
Upon access to the web pages on the CPE side of the router, if the user has not changed the default
web password, a warning message must be displayed in the top banner of the web interface such as
being visible while accessing any tabs.
This warning message informs the user that the default password must be changed:
In the
second sentence, “here” is a hyperlink to the password setting page. Clicking on “here” lead to the
display of the password setting page.
More information
By default, the username is empty (“”) and the password is “admin”.
This is set by different actions (non exhaustive list):
- at the manufactory level,
- following a reset factory on the modem,
- following a reset from the operator,
- following a change by the user who wants to come back to the default setting after using its own
settings
When the current password is the default one, the user is strongly encouraged to change the default
web password:
- Once the user logs in the web pages, the password setting page is displayed
- the warning message must be displayed in the top banner of the web interface
- The user can still access to all the web pages even if the password is not changed
- The warning message must be displayed on the top banner of each accessed Web page while the
password is not changed
- The password warning message must be visible while accessing all tabs in a the same web page

The password warning message is no more displayed on the banners once the default
password has been replaced by a new one.
At your first connection or while the password is the default one, a warning message is displayed on
the top banner of each Web configuration page. We want to encourage you to change the password in
order to enforce the security of your modem.
The password can be a maximum of 8 characters and is case sensitive. In addition, this page can be
used to restore the gateway to its original factory settings. Use this with caution, as all the settings you
have made will be lost. To perform this reset, set Restore Factory Defaults to Yes and click Apply.
This has the same effect as a factory reset using the rear panel reset switch, where you hold on the
switch for 15 seconds, then release it.

For example, you could block access to worldwide web browsing (http = port 80) but still allow email
service (SMTP port 25 and POP-3 port 110). To enable port filtering, set Start Port and End Port for
each range, and click Apply. To block only one port, set both Start and End ports with the same value.

5. Forwarding
For LAN ꢂ WAN communications, the gateway normally only allows you to originate an IP
connection with a PC on the WAN; it will ignore attempts of the WAN PC to originate a connection
onto your PC. This protects you from malicious attacks from outsiders. However, sometimes you may
wish for anyone outside to be able to originate a connection to a particular PC on your LAN if the
destination port (application) matches one you specify.
This page allows you to specify up to 10 such rules. For example, to specify that outsiders should have
access to an FTP server you have running at 192.168.0.5, create a rule with that address and Start Port
=20 and End Port =21 (FTP port ranges) and Protocol = TCP (FTP runs over TCP and the other
transport protocol, UDP), and click Apply. This will cause inbound packets that match to be forwarded
to that PC rather than blocked. As these connections are not tracked, no entry is made for them in the
Connection Table. The same IP address can be entered multiple times with different ports.

6. Port Triggers
Some Internet activities, such as interactive gaming, require that a PC on the WAN side of your
gateway be able to originate connections during the game with your game playing PC on the LAN side.
You could use the Advanced-Forwarding web page to construct a forwarding rule during the game,
and then remove it afterwards (to restore full protection to your LAN PC) to facilitate this. Port
triggering is an elegant mechanism that does this work for you, each time you play the game.

Chapter 2: WEB Configuration
Fig. 22
Port Triggering works as follows. Imagine you want to play a particular game with PCs somewhere on
the Internet. You make one time effort to set up a Port Trigger for that game, by entering into Trigger
Range the range of destination ports your game will be sending to, and entering into Target Range
the range of destination ports the other player (on the WAN side) will be sending to (ports your PC’s
game receives on). Application programs like games publish this information in user manuals. Later,
each time you play the game, the gateway automatically creates the forwarding rule necessary. This
rule is valid until 10 minutes after it sees game activity stop. After 10 minutes, the rule becomes
inactive until the next matched outgoing traffic arrives.
For example, suppose you specify Trigger Range from 6660 to 6670 and Target Range from 113 to
113. An outbound packet arrives at the gateway with your game-playing PC source IP address
192.168.0.10, destination port 666 over TCP/IP. This destination port is within the Trigger destined for
port 113 to your game-playing PC at 192.168.0.10.
You can specify up to 10 port ranges on which to trigger.

7. DMZ Host
Use this page to designate one PC on your LAN that should be left accessible to all PCs from the
WAN side, for all ports. For example, if you put an HTTP server on this machine, anyone will be able
to access that HTTP server by using your gateway IP address as the destination. A setting of “0”
indicates NO DMZ PC. “Host” is another Internet term for a PC connected to the Internet.
Fig. 23
8. RIP (Routing Information Protocol) Setup
This feature enables the gateway to be used in small business situations where more than one LAN
(local area network) is installed. The RIP protocol provides the gateway a means to “advertise”
available IP routes to these LANs to your cable operator, so packets can be routed properly in this
situation.
Your cable operator will advise you during installation if any setting changes are required here.

Important: Changes to the wireless web pages should be made from a PC that is hard
wired to the gateway, i.e. via Ethernet.
The Wireless web pages group enables a variety of settings that can provide secure and reliable
wireless communications for even the most demanding tech-savvy user.
The Wireless Voice Gateway offers a choice of 802.1x, WPA and WPA-PSK authentication of your
PCs to the gateway, 64 and 128 bit WEP encryption of communication between the gateway and your
PCs to guaranty security, and an Access Control List function that enables you to restrict wireless
access to only your specific PCs.
The wireless function will probably work in your home as shipped from the factory, but without the
security features activated. In addition, the factory default wireless channel setting may not provide
optimum changes are recommended from the factory defaults, to secure your wireless communications
and provide optimum performance.
Performance
Because your wireless communication travels through the air, the factory default wireless channel
setting may not provide optimum performance in your home if you or your neighbors have other
interfering 2.4GHz devices such as cordless phones. If your wireless PC is experiencing very sluggish
or dramatically slower communication compared with the speed you achieve on your PC that is wired
to the gateway, try changing the channel number. See the 802.11b/g Basic Web Page discussion below
for details.
Authentication
Authentication enables you to restrict your gateway from communicating with any remote wireless
PCs that aren’t yours. The following minimum authentication-related changes to factory defaults are
recommended. See the 802.11b/g Basic and Access Control Web Page discussions below for details.
Network Name (SSID) – Set a unique name you choose

Chapter 3: Networking
Communications
Data communication involves the flow of packets of data from one device to another. These
devices include personal computers, Ethernet and USB hubs, cable modems, digital routers
and switches, and highly integrated devices that combine functions, like the Wireless Cable
Gateway.
The gateway integrates the functionality often found in two separate devices into one. It’s
both a cable modem and an intelligent wireless gateway networking device that can provide a
host of networking features, such as NAT and firewall. Figure 2 illustrates this concept, with
the cable modem (CM) functionality on the left, and networking functionality on the right. In
this figure, the numbered arrows represent communication based on source and destination,
as follows:
Type of Communication
1. Communication between the Internet and your PCs
Example: The packets created by your request for a page stored at a web site, and the
contents of that page sent to your PC.
2. Communication between your cable company and the cable modem side
Example: When your cable modem starts up, it must initialize with the cable company,
which requires the cable company to communicate directly with the cable modem itself.
3. Communication between your PCs and the networking side

Chapter 3: Networking
Fig.11
Example: The Wireless Cable Gateway offers a number of built-in web pages which you
can use to configure its networking side; when you communicate with the networking
side, your communication is following this path.
Each packet on the Internet addressed to a PC in your home travels from the Internet down-
stream on the cable company’s system to the WAN side of your Wireless Cable Gateway. There
it enters the Cable Modem section, which inspects the packet, and, based on the results,
proceeds to either forward or block the packet from proceeding on to the Networking section.
Similarly, the Networking section then decides whether to forward or block the packet from
proceeding on to your PC. Communication from your home device to an Internet device works
similarly, but in reverse, with the packet traveling upstream on the cable system.

Chapter 3: Networking
Cable Modem (CM) Section
The cable modem (or CM) section of your gateway uses EURO-DOCSIS Standard cable modem
technology. EURO-DOCSIS specifies that TCP/IP over Ethernet style data communication be
used between the WAN interface of your cable modem and your cable company.
A EURO-DOCSIS modem, when connected to a Cable System equipped to support such
modems, performs a fully automated initialization process that requires no user intervention.
Part of this initialization configures the cable modem with a CM IP (Cable Modem Internet
Protocol) address, as shown in Figure 3, so the cable company can communicate directly with
the CM itself.
Networking Section
The Networking section of your gateway also uses TCP/IP (Transmission Control Protocol/
Internet Protocol) for the PCs you connected on the LAN side. TCP/IP is a networking protocol
that provides communication across interconnected networks, between computers with
diverse hardware architectures and various operating systems.
TCP/IP requires that each communicating device be configured with one or more TCP/IP
stacks, as illustrated by Figure 4. On a PC, you often use software that came with the PC or its
network interface (if you purchased a network interface card separately) to perform this
configuration. To communicate with the Internet, the stack must also be assigned an IP
(Internet Protocol) address. 192.168.100.1 is an example of an IP address. A TCP/IP stack can
71

Download from Www.Somanuals.com. All Manuals Search And Download.
Chapter 3: Networking
be configured to get this IP address by various means, including a DHCP server, by you
directly entering it, or sometimes by a PC generating one of its own.
Ethernet requires that each TCP/IP stack on the Wireless Cable Gateway also have associated
with it an Ethernet MAC (Media Access Control) address. MAC addresses are permanently
fixed into network devices at the time of their manufacture. 00:90:64:12:B1:91 is an example
of a MAC address.
Data packets enter and exit a device through one of its network interfaces. The gateway offers
Ethernet, USB, and 802.11b/g wireless network interfaces on the LAN side and the
EURO-DOCSIS network interface on the WAN side.
When a packet enters a network interface, it is offered to all the TCP/IP stacks associated with
the device side from which it entered. But only one stack can accept it — a stack whose
configured Ethernet address matches the Ethernet destination address inside the packet.
Furthermore, at a packet’s final destination, its destination IP address must also match the IP
address of the stack.
Each packet that enters a device contains source MAC and IP addresses telling where it came
from, and destination MAC and IP addresses telling where it is going to. In addition, the
packet contains all or part of a message destined for some application that is running on the
destination device. IRC used in an Internet instant messaging program, HTTP used by a web
browser, and FTP used by a file transfer program are all examples of applications. Inside the

packet, these applications are designated by their port number. Port 80, the standard HTTP
port, is an example of a port number.
The Networking section of the router performs many elegant functions by recognizing
different packet types based upon their contents, such as source and destination MAC
address, IP address, and ports.
Three Networking Modes
Your gateway can be configured to provide connectivity between your cable company and
your home LAN in any one of three Networking Modes: CM, RG, and CH. This mode setting is
under the control of your cable company, who can select the mode to match the level of home
networking support for which you have subscribed. All units ship from the factory set for the
RG mode, but a configuration file which the cable company sends the cable modem section
during its initialization can change it.

Chapter 3: Networking
• IP Stack 1 - for use by the cable company to communicate with the cable modem section
only. This stack receives its IP address from the cable company during CM initialization. It
uses the MAC address printed on the label attached to the Wireless Cable gateway.
• IP Stack 2 - for use by you, the end user, to communicate with the cable modem and
Networking sections, to access the internal web page diagnostics and con guration. This
stack uses a fixed IP address: 192.168.100.1. It uses a MAC address of MAC label + 1 (the
MAC label is found on the bottom of the unit). E.g., if the MAC address is
00:90:64:12:B1:91, this MAC address would be 00:90:64:12:B1:92.
With CM Mode, your cable company must provide one IP address for the CM section, plus one
for each PC you connect from their pool of available addresses. Your cable company may have
you or your installer manually enter these assigned addresses into your PC, or use a DHCP
Server to communicate them to your PCs, or use a method that involves you entering host
names into your PCs.
Note that in CM Mode, packets passing to the Internet to/from your PCs do not travel through
any of the IP stacks; instead they are directly bridged between the WAN and LAN sides.

uses the MAC address printed on the label attached to the Wireless Cable Gateway.
• IP Stack 3 - for use by you to remotely (i.e. from somewhere on the WAN side, such as at
your remote workplace) communicate with the Cable Modem and Networking sections, to
remotely access the internal web page diagnostics and configuration. This stack is also
used by your cable company to deliver packets between the Internet and the gateway’s
networking section so they can be routed to/from your PCs. This stack requires an IP
address assigned by the cable company from their pool of available addresses. Your cable
company may have you or your installer manually enter assigned addresses into your
gateway, or use a DHCP Server to communicate them, or use a method that involves you
entering host names. This stack uses a MAC address of MAC label + 2 (the MAC label is
found on the bottom of the unit). E.g., if the MAC address is 00:90:64:12:B1:91, this MAC
address would be 00:90:64:12:B1:93.
• IP Stack 5 - for use by you to locally (i.e. from somewhere on the LAN side in your home)
communicate with the Cable Modem and Networking sections, to access the internal web
page diagnostics and configuration. This stack is also used by the gateway’s networking
section to route packets between the gateway’s Networking section and your PCs. This
stack uses a fixed IP address: 192.168.0.1. It uses a MAC address of MAC label + 4 (the
MAC label is found on the bottom of the unit). E.g., if the MAC address is
00:90:64:12:B1:91, this MAC address would be 00:90:64:12:B1:95.
