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 wired and wireless 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 head end 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 DOCSIS-compliant and PacketCable-compliant technology.
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).
The Internet/Telephony Service Provider (ISP/TSP):
Check with your cable company to make sure you have everything you need to begin; they’ll know if

Chapter 1: Connections and Setup
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
Please verify the following with the cable company
The cable service to your home supports 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.
Note: It is important to supply power to the modem at all times. Keeping your modem plugged in will
keep it connected to the Internet. This means that it will always be ready whenever you need.
Important Information
Your cable company should always be consulted before installing a new cable outlet. Do not attempt any
rewiring without contacting your cable company first.

Chapter 1: Connections and Setup
Connecting the Residential Voice Gateway to a Single Computer
This section of the manual explains how to connect your Residential Voice Gateway to the Ethernet port
on your computer and install the necessary software. Please refer to Figure 1 to help you connect your
Digital Cable Modem for the best possible connection.
Attaching the Cable TV Wire to the Residential Voice Gateway
1. Locate the Cable TV wire. You may find it one of three ways:
a.
Connected directly to a TV, a Cable TV converter box, or VCR. The line will be connected to
the jack which should be labeled either IN, CABLE IN, CATV, CATV IN, etc.
b.
Connected to a wall-mounted cable outlet.
c.
Coming out from under a baseboard heater or other location. See Figure 1 for the wiring
example.
Notes: For optimum performance, be sure to connect your
Residential Voice Gateway to the first point the cable enters
your home. The splitter must be rated for at least 1GHz.
Fig. 1:
Basic Home Wiring
Important Connection Information
The Residential Voice Gateway supports Telephone and Ethernet connections simultaneously.
13
Illustrations contained in this document are for representation only.
Chapter 1: Connections and Setup
Below are important points to remember before you connect the Residential Voice Gateway.
For Ethernet connections, go to page 14.
For telephone and fax connections, go to page 16.
Ethernet Connection to One Computer
Make the connections to the modem in the following sequence:
1. Connect one end of the coaxial cable to the cable connection on the wall, and the other end to the
CABLE jack on the Residential Voice Gateway.
2. Connect the plug from the AC power supply into the DC jack on the Residential Voice Gateway, and
plug the power supply into an AC outlet.
3. Note: Use only the power supply that accompanied this unit. Using other adapters may damage the
unit. Connect one end of the Ethernet cable (straight-wired, see below) to the Ethernet port on the
back of your computer, and the other end to the ETHERNET port on the Residential Voice Gateway.
Make sure that the Ethernet cable is straight-wired (not “null” or crossover-wired). However, you
will need a crossover-type cable if you are connecting the modem to a hub, or a hub within a port
switch that provides the same function.

Chapter 1: Connections and Setup
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 cannot use your modem
during this time. Do not remove the power supply or reset the Residential Voice Gateway during this
process.
For a better wireless reception/connectivity, please make sure the supplied Wireless antenna is connected

gateway, and your gateway’s DHCP server provides IP addresses, starting at the address you set in IP
Address on the LAN page, to your PCs. A DHCP server leases an IP address with an expiration time.
To change the lowest IP address that your gateway will issue to your PCs, enter it into the IP Address
box and then click Apply.

4. DDNS
Dynamic DNS (DDNS) allows a dynamic IP address to be aliased to a static, pre-defined host name so
that the host can be easily contacted by other hosts on the internet even if its IP address changes. The
CMRG supports a dynamic CNS client compatible with the Dynamic DNS service
(http://www.dyndns.com/).

Go to the DynDNS website and create an account for the Dynamic DNS service. You will create a
username and password, and be asked to choose a host name for your host’s current IP address. This
is the WAN IP address that has been assigned to your CMRG during provisioning.
Enter your account information on the DDNS web page, enable the service by selecting
www.DynDNS.org from the DDNS Service drop-down list, and click “Apply”.
The DDNS client will notify the DDNS service whenever the WAN IP address changes so that your
chosen host name will be resolved properly by inquiring hosts. The current status of the service is
shown at the bottom of the DDNS web page.

Gateway – Advanced Web Page Group
1. Options
This page allows you to enable/disable some features of the Residential Voice Gateway.
Fig. 18 Gateway\Advnaced\Options
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 LAN. IpSec (IP Security) is a
security mechanism used in Virtual Private Networks (VPNs).
PPTP PassThrough enables PPTP type packets to pass WAN 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 WAN LAN. You may need to enable this to
see some types of broadcast streaming and content on the Internet.

2. 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 (Internet). These PCs can still communicate with each other on your LAN,
but traffic they originate to the WAN is blocked by the gateway.

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.

4. 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
5. Forwarding
For LAN 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
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.
Fig. 23 Gateway\Advnaced\Port Triggers
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.

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.

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 directly connected 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 DWG855 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
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)

Network to Enable, your SSID is included in that beacon, and is therefore detectable by any nearby wireless
equipped PCs in the area. The benefit of using Enable is it can speed your WiFi setup on some PCs. If you set
Closed Network to Disable, your SSID is not included in the beacon. This hides your network name (SSID), but as
a result may require a bit more effort on your part to set up your wireless PCs. And when we Enable the WPS
Config then the Closed Network will be Disabled automatically.
WPA (Wi-Fi Protected Access)/WPA2:
It must be used in conjunction with an authentication server such as RADIUS to provide centralized
access control and management. It can provide stronger encryption and authentication solution than none
WPA modes. WPA2 is the second generation of WPA security
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 transmitted.
For example, if you set 128-bit in this field, then the receiving station must be set to use the128 Bit
Encryption, and have the same Key value too. Otherwise, it will not be able to decrypt the data.
( Note: You need to connect one end of the Ethernet cable to the Ethernet port on the back of your
computer, and the other end to the ETHERNET port on the Residential Voice Gateway. )
If you select WEP (64-bit or 128-bit), you can adjust the following settings-
Shared Key Authentication: Decide whether to set the shared key Optional or Required by
selecting from the drop-down menu.
Network Key 1 to 4: The system allows you to enter four sets of the WEP key. For 64-bit WEP
mode, the key length is 5 characters or 10 hexadecimal digits. As for 128-bit WEP mode, the key
length is 13 characters or 26 hexadecimal digits.
Current Network Key: Select one set of the network key (from 1 to 4) as the default one.
PassPhrase: You can enter ASCII codes into this field. The range is from 8 characters to 64
characters. For ASCII characters, you can key in 63 characters in this field. If you want to key in 64

WPA/WPA2 Encryption: There are three types that you can choose, TKIP*, AES**, TKIP+AES.
TKIP takes the original master key only as a starting point and derives its encryption keys
mathematically from this mater key. Then it regularly changes and rotates the encryption
keys so that the same encryption key will never be used twice
** AES provides security between client workstations operating in ad hoc mode. It uses a
mathematical ciphering algorithm that employs variable key sizes of 128, 192 or 256 bits.
RADIUS Server/RADIUS Port/RADIUS Key: Please refer to the previous page.
Group Key Rotation Interval: Key in the time for the WAP group key rotation interval. The unit is
second. With increasing rekey interval, user bandwidth requirement is reduced.
WPA/WPA2 Re-auth Interval: When a wireless client has associated with the Residential Voice
Gateway for a period of time longer than the setting here, it would be disconnected and the
authentication will be executed again. The default value is 3600, you may modify it.

Frequently Asked Questions
Q. What if I don’t subscribe to cable TV?
A. If cable TV is available in your area, data and voice service may be made available with or without
cable TV service. Contact your local cable company for complete information on cable services,
including high-speed internet access.
Q. How do I get the system installed?
A. Professional installation from your cable provider is strongly recommended. They will ensure proper
cable connection to the modem and your computer. However, your retailer may have offered a self
installation kit, including the necessary software to communicate with your cable 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 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 Residential Voice
Gateway will work with all upgraded cable systems that are DOCSIS-compliant.
Q. What is PacketCable and what does it mean?
A. Like DOCSIS, 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 PacketCable-compliant.
Q. What is Xpress Technology and what does it mean?

Chapter 3: Additional Information
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 re-packaging data, reducing the number of overhead control
packets, so that more useful data can be sent during a given amount of time.
* Monthly subscription fee may apply.
** Additional equipment required. Contact your Cable Company and ISP for any restrictions or
additional fees.

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.
Check all of the connections to your Residential Voice Gateway.
Your Ethernet card may not be working. Check each product’s documentation for more
information.
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 or some of the lights are flashing in sequence.
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.
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.
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.
Check to see that you are using the right type of Ethernet cable.
The modem won’t register a cable connection.
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 22 for details.)
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.
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
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.
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.
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.
If using the second line on a two-line telephone, be sure to connect to port TEL1/2.
For more Usage and Troubleshooting Tips use the web site links provided on the CD-ROM.
