Relationship among the Devices
This illustration shows a cable company that offers DOCSIS- and PacketCable-compliant
voice/data services.
What the Modem Does
The Residential 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 PacketCable compliant headend equipment and provide the IP-based voice
communications. The IP traffic can transfer between the Residential Voice Gateway and DOCSIS
compliant headend 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 or DOCSIS-compliant and
Euro-PacketCable or 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).

Telephone or Fax Connection
When properly connected, most telephony devices can be used with the Residential Voice
Gateway just as with conventional telephone service. To make a normal telephone call, pick up
the handset; listen for a dial tone, then dial the desired number. For services such as call waiting,
use the hook switch (or FLASH button) to change calls. The following procedures describe some
of the possible connection schemes for using telephony devices with the Residential Voice
Gateway.
1. Connect a standard phone line cord directly from the phone (fax machine, answering
machine, caller ID box, etc.) to one of the LINE jacks on the Residential Voice Gateway.
2. If there is a phone line in your home which is NOT connected to another telephone service
provider, connect a standard phone line cord from a jack on this line to one of the LINE jacks
of the Residential Voice Gateway. Connect a standard phone line cord directly from the phone
(fax machine, answering machine, caller ID box, etc.) to one of the other jacks in the house
that uses that line.
3. If you have a multi-line telephone, connect a standard phone line cord (not an RJ-14 type line
cord) from the phone to the LINE jacks on the Residential Voice Gateway. (Other phones can
be added to each line by using standard phone line splitters.

Chapter 1: Connections and Setup
Activating the Residential Voice Gateway
After installing the Residential Voice Gateway and turn it on for the first time (and each time the
modem is reconnected to the power), it goes through several steps before it can be used. Each of
these steps is represented by a different pattern of flashing lights on the front of the modem.
Note: All indicators flash once before the initialization sequence.
If all of the lights are flashing sequentially, it means the Residential Voice Gateway is
automatically updating its system software. Please wait for the lights to stop flashing. You

WAN Blocking prevents others on the WAN side from being able to ping your gateway.
With WAN Blocking enabled, your gateway will not respond to pings it receives,
effectively “hiding” your gateway.
Ipsec PassThrough enables IpSec type packets to pass WAN Ù LAN. IpSec (IP Security) is
a security mechanism used in Virtual Private Networks (VPNs).
PPTP PassThrough enables PPTP type packets to pass WAN Ù LAN. PPTP (Point to Point
Tunneling Protocol) is another mechanism sometimes used in VPNs.
Remote Config Management makes the configuration web pages in your gateway
accessible from the WAN side. Note that page access is limited to only those who know
the gateway access password. When accessing your gateway from a remote location,
your must use HTTP port 8080 and the WAN IP address of the gateway. For example, if
the WAN IP address is 157.254.5.7, you would navigate to http://157.254.5.7:8080 to
reach your gateway.
Multicast Enable enables multicast traffic to pass WANÙ LAN. You may need to enable
this to see some types of broadcast streaming and content on the Internet.

IP Filtering
This page enables you to enter the IP address ranges of PCs on your LAN that you don’t
want to have outbound access to the WAN. These PCs can still communicate with each
other on your LAN, but packets they originate to WAN addresses are blocked by the
gateway.
Fig. 18
MAC Filtering
This page enables you to enter the MAC address of specific PCs on your LAN that you
wish to NOT have outbound access to the WAN. As with IP filtering, these PCs can still
communicate with each other through the gateway, but packets they send to WAN
addresses are blocked.

Port Filtering
This page allows you to enter ranges of destination ports (applications) that you don’t
want your LAN PCs to send packets to. Any packets your LAN PCs send to these
destination ports will be blocked. 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 the same.

Chapter 2: Web Configuration
Forwarding
For LAN Ù 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.

Chapter 2: Web Configuration
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.
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.

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
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.

Gateway – Wireless Web Page Group
Important: Changes to the wireless web pages should be made from a PC that is hard
wired to the gateway.
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 TWG850 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
Network Type – Set to Open
Access Control List – Enter your wireless PCs’ MAC addresses

Chapter 2: Web Configuration
Security
Security secures or scrambles messages traveling through the air between your wireless
PCs and the gateway, so they can’t be observed by others. The following minimum
security setting changes to factory defaults are recommended. See the 802.11b/g
Security Web Page discussion below for details.
Data Encryption – Set to WEP (64-bit)
PassPhrase – Use this feature to generate security keys
802.11b/g Basic
To set the basic configuration for the wireless features, click Basic from the Wireless menu.
These must match the settings you make on your wireless-equipped PC on the LAN side.
The SSID is your Network Name. Change the factory default to a name of your choice up to 32
characters long. The wireless radio in your gateway can be completely de-activated by changing
Interface to Disabled. Click the Apply button to save your settings.
The Network Type control is used to hide or reveal your network name to any remote, wireless
equipped PC in the area that may be scanning WiFi channels to find available WiFi networks. The
gateway WiFi radio frequently transmits a beacon signal which can contain this network name
(SSID). If you set Network Type to Open, your SSID is included in that beacon, and is therefore
detectable by any nearby wireless equipped PCs in the area. The benefit of using Open is it can
speed your WiFi setup on some PCs. If you set Network Type to Closed, your SSID is not included
in the beacon. This hides your network name, but as a result may require a bit more effort on
your part to set up your wireless PCs. Details of all settings on the 802.11b/g Basic Web Page are
provided in Table 1.

authentication solution than none WPA modes.
WPA-PSK (WPA-Pre-Shared Key) /WPA2-PSK (WPA2-Pre-Shared Key):
It is useful for small places without authentication servers such as the network at home. It allows
the use of manually-entered keys or passwords and is designed to be easily set up for home
users.
WEP Encryption:
You can choose 64-bit or 128-bit according to your needs. If you choose Disabled, the Network
Keys will not be shown on this page. If selected, the data is encrypted using the key before being

ISP.
Q. Once my Residential Voice Gateway is connected, how do I get access to the Internet?
A. Your local cable company provides your internet service*, offering a wide range of services
including email, chat, and news and information services, and a connection to the World Wide
Web.
Q. Can I watch TV, surf the Internet, and talk to my friends through the Residential Voice
Gateway at the same time?
A. Absolutely!
Q. What do you mean by “Broadband?”
A. Simply put, it means you’ll be getting information through a “bigger pipe,” with more
bandwidth, than a standard phone line can offer. A wider, “broader” band means more
information, more quickly.
Q. What is EURO-DOCSIS/DOCSIS and what does it mean?
A. “Data over Cable Service Interface Specifications” is the industry standard that most cable
companies are adopting as they upgrade their systems. Should you ever decide to move, the
Cable Modem will work with all upgraded cable systems that are
EURO-DOCSIS/DOCSIS-compliant.

Q. What is Euro-PacketCable/PacketCable and what does it mean?
A. Like DOCSIS, Euro-PacketCable/PacketCable is the industry standard for telephony services
that most cable companies are adopting as they upgrade their systems. Should you ever decide
to move, the Residential Voice Gateway will work with all upgraded cable systems that are
Euro-PacketCable/PacketCable-compliant.
Q. What is SecureEasySetup and what does it mean?
A. The software radically simplifies Wi-Fi® wireless LAN configuration, allowing even first-time
Wi-Fi users to setup and secure their wireless networks with the push of a button. Whereas a
typical Wi-Fi installation requires a user to manually configure several technical settings on each
wireless device, SecureEasySetup simply requires a user to push a button on the wireless router/
Access Point, and a corresponding button on the PC or other client device. This automates the
connection process and activates Wi-Fi Protected Access (WPA), the strongest security standard
available to protect home and small business wireless networks from unauthorized use.
Q. What is Xpress Technology and what does it mean?
A. It is one of the popular performance-enhancing WiFi technologies, designed to improve
wireless network efficiency and boost throughput. It is more efficient in mixed environments,
and it can work with 802.11a/b/g networks. When Xpress is turned on, aggregate throughput
(the sum of the individual throughput speeds of each client on the network) can improve by up
to 27% in 802.11g-only networks, and up to 75% in mixed networks comprised of 802.11g and
802.11b standard equipment. The technology achieves higher throughput by by re-packaging
data, reducing the number of overhead control packets, so that more useful data can be sent
during a given amount of time.

General Troubleshooting
You can correct most problems you have with your product by consulting the troubleshooting
list that follows.
I can’t access the internet.
z Check all of the connections to your Residential Voice Gateway.
z Your Ethernet card or USB port may not be working. Check each product’s
documentation for more information.
z The Network Properties of your operating system may not be installed correctly or the
settings may be incorrect. Check with your ISP or cable company.
All of the lights are flashing in sequence.
z This means the Residential Voice Gateway is automatically updating its system software.
Please wait for the lights to stop flashing. The updating process typically lasts less than
one minute.
z Do not remove the power supply or reset the Residential Voice Gateway during this
process.
I can’t get the modem to establish an Ethernet connection.
z Even new computers don’t always have Ethernet capabilities – be sure to verify that your
computer has a properly installed Ethernet card and the driver software to support it.
z Check to see that you are using the right type of Ethernet cable.
The modem won’t register a cable connection.
z If the modem is in Initialization Mode, the INTERNET light will be flashing. Call your
Cable Company if it has not completed this 5-step process within 30 minutes, and note
which step it is getting stuck on. (See page 5 for details.)
z The modem should work with a standard RG-6 coaxial cable, but if you’re using a cable
other than the one your Cable Company recommends, or if the terminal connections are
loose, it may not work. Check with your Cable Company to determine whether you’re
using the correct cable.
z If you subscribe to video service over cable, the cable signal may not be reaching the
modem. Confirm that good quality cable television pictures are available to the coaxial
connector you are using by connecting a television to it. If your cable outlet is “dead”,
call your Cable Company.

Chapter 3: Additional Information
z Verify that the Cable Modem service is DOCSIS-compliant and PacketCable-compliant by
calling your cable provider.
I don’t hear a dial tone when I use a telephone.
z Telephone service is not activated. If the rightmost light on the Residential Voice
Gateway stays on while others flash, check with your TSP or cable company.
z If the Residential Voice Gateway is connected to existing house telephone wiring, make
sure that another telephone service is not connected. The other service can normally be
disconnected at the Network Interface Device located on the outside of the house.
z If using the second line on a two-line telephone, use a 2-line to 1-line adapter cable.
