Where Is the Best Location for My DOCSIS Residential Gateway?  
Where Is the Best Location for My DOCSIS Residential  
Gateway?  
The ideal location for your residential gateway is where it has access to outlets and  
other devices. Think about the layout of your home or office, and consult with your  
service provider to select the best location for your residential gateway. Read this  
user guide thoroughly before you decide where to place your residential gateway.  
Consider these recommendations:  
Choose a location close to your computer if you will also use the residential  
gateway for high-speed Internet service.  
Choose a location that is near an existing RF coaxial connection to eliminate the  
need for an additional RF coaxial outlet.  
Choose a location for the residential gateway that is adjacent to your telephone  
equipment if you are using only one or two pieces of telephone equipment.  
Note: If you are using the residential gateway to provide service to several  
telephones, a professional installer can connect the residential gateway to your  
existing home telephone wiring. To minimize changes to the home telephone  
wiring, you may want to locate the residential gateway near an existing  
telephone outlet.  
Choose a location that is relatively protected from accidental disturbance or  
harm, such as a closet, basement, or other protected area.  
Choose a location so that there is plenty of room to guide the cables away from  
the modem without straining or crimping them.  
Airflow around the residential gateway should not be restricted.  
Read this user guide thoroughly before installing the residential gateway.

How Do I Mount the Modem on a Wall? (Optional)  
You can mount the residential gateway on a wall using two wall anchors, two  
screws, and the mounting slots located on the unit. The modem can be mounted  
vertically or horizontally.  
Before You Begin  
Before you begin, choose an appropriate mounting place. The wall can be made of  
cement, wood, or drywall. The mounting location should be free of obstructions on  
all sides, and the cables should be able to easily reach the residential gateway  
without strain. Leave sufficient clearance between the bottom of the residential  
gateway and any flooring or shelving underneath to allow access to cabling. In  
addition, leave enough slack in all cables so that the residential gateway can be  
removed for any required maintenance without disconnecting the cables. Also,  
verify that you have the following items:  
Two wall anchors for #8 x 1-inch screws  
Two #8 x 1-inch pan head sheet metal screws  
Drill with a 3/16-in. wood or masonry bit, as appropriate for the wall

What Are the Requirements for Telephone Service?  
What Are the Requirements for Telephone Service?  
Number of Telephone Devices  
The RJ-11 telephone-style connectors on the residential gateway can each provide  
telephone service to multiple telephones, fax machines, and analog modems.  
The maximum number of telephone devices connected to each RJ-11 port is limited  
by the total Ringing Load of the telephone devices that are connected. Many  
telephone devices are marked with a Ringer Equivalent Number (REN). Each  
telephone port on the residential gateway can support up to a 5 REN load.  
The sum of the REN load on all of the telephone devices attached to each port must  
not exceed 5 REN.  
Telephone Device Types  
You can use telephone devices that are not labeled with a REN number, but the  
maximum number of attached telephone devices cannot be accurately calculated.  
With telephone devices that are not labeled, each device should be connected and  
the ring signal should be tested before adding more devices. If too many telephone  
devices are attached and the ring signal can no longer be heard, telephone devices  
should be removed until the ring signal works properly.  
Telephones, fax machines, and other telephone devices should use the center 2 pins  
of the RJ-11 connectors to connect to the residential gateway telephone ports. Some  
telephones use other pins on the RJ-11 connectors and require adapters in order to  
work.  
Dialing Requirements  
All your telephones should be set to use DTMF dialing. Pulse dialing is typically not  
enabled by your local provider.  
Telephone Wiring Requirements  
The residential gateway supports connecting to the interior telephone wiring as well  
as connecting directly to a telephone or fax machine. The maximum distance from  
the unit to the most distant telephone device must not exceed 1000 feet (300 meters).  
Use 26-gauge twisted-pair, or larger, telephone wiring.  
Important: Connection to an existing or a new permanently installed home  
telephone wiring network must be done by a qualified installer.

WARNING:  
To avoid personal injury, follow the installation instructions in the exact  
order shown.  
To prevent possible damage to equipment, disconnect any other telephone  
service before connecting your cable modem to the same wires.  
Hazardous electrical voltages can exist on the telephone ports on the  
residential gateway and can be present on any connected wiring including  
Ethernet wiring, telephone wiring and coax cable.  
Telephone wiring and connections must be properly insulated to prevent  
electrical shock.  
Telephone connections to an installed home telephone wiring network  
must be done by a qualified installer. The cable telephone service  
provider may offer professional installation and connection to the home  
telephone wiring network. A fee may be charged for this service.  
Wiring and connections must be properly insulated to prevent electrical  
shock.  
Disconnect power from the residential gateway before attempting to  
connect to any device.  
2
3
Power off your PC and other networking device; then, unplug them from the  
power source.  
Connect the active RF coaxial cable from your service provider to the coax  
connector labeled CABLE on the back of the residential gateway.  
Note: To connect a TV, DHCT, set-top, or VCR from the same cable connection,  
you will need to install a cable signal splitter (not included). Always check with  
your service provider before using a splitter as a splitter may degrade the signal.  
4
Connect your PC to the residential gateway using either of the following  
methods.  
Ethernet Connection: Locate the yellow Ethernet cable, connect one end of  
the Ethernet cable to the Ethernet port on your PC, and connect the other end  
to the yellow ETHERNET port on the back of the residential gateway.  
Note: To install more Ethernet devices than ports provided on the residential  
gateway, use an external multi-port Ethernet switch(s).  
Wireless: Make sure that your wireless device is powered up. You will need  
to associate your wireless device with the wireless gateway once the gateway  
is operational. Follow the directions provided with your wireless device for  
associating with a wireless access point.

Connect one end of a telephone jumper cable (not included) to a telephone outlet  
in your home or to a telephone or fax machine. Then connect the other end of the  
jumper cable to the appropriate RJ-11 TELEPHONE port on the back of the  
residential gateway. The telephone ports are light gray and are labeled 1/2 and 2  
or 1 and 2 depending on the region of the world the residential gateway is used.  
Notes:  
Make sure to connect your telephone service to the correct RJ-11 port. For  
single line telephone service, connect to port 1/2 or 1.  
In North America, residential gateways have multi-line capability on the  
RJ-11 telephone port labeled 1/2. Line 1 is on pins 3 and 4 of port 1/2,  
and Line 2 is supported on pins 2 and 5. In Europe, residential gateways  
support only one line per port. Line 1 is on port 1 and line 2 is on port 2.  
Telephones that require electrical connectors other than RJ-11 may  
require an external adapter (sold separately).  
6
Locate the AC power cord provided with your residential gateway. Insert one  
end of the power cord into the AC connector on the back of the residential  
gateway. Then, plug the AC power cord into an AC outlet to power-up the  
residential gateway. The residential gateway will perform an automatic search to  
locate and sign on to the broadband data network. This process may take up to 2-  
5 minutes. The modem will be ready for use when the POWER, DS, US and  
ONLINE LEDs on the front panel of the residential gateway stop blinking and  
remain on continuously.  
7
8
Plug in and power on your PC and other home network devices. The LINK LED  
on the residential gateway corresponding to the connected devices should be on

WPA  
Security for Personal Networks WPA or WPA2 Personal Modes  
Wi-Fi Protected Access (WPA) is a more secure wireless technology than WEP. WPA can be used  
for both Enterprise (corporate applications) and Personal (home network) wireless networks. We  
strongly recommend that you select either WPA-Personal or WPA2-Personal as the security mode  
for your home network, depending on which mode is supported by the wireless adapter in your  
PC or wireless clients.  
WPA-Personal (aka WPA-PSK or WPA-Pre-Shared Key), provides a more secure wireless  
network that WEP. WPA-Personal introduces TKIP user authentication and stronger encryption  
keys than WEP.  
WPA2-Personal (aka WPA2-PSK or WPA2-Pre-Shared Key) provides the most secure standards-

Field Description  
DTIM Interval  
The Delivery Traffic Indication Message (DTIM) indicates the interval between  
Broadcasts/Multicast transmissions. DTIM field is a countdown field informing  
clients of the next window for listening to broadcast and multicast messages. When  
the device has buffered broadcast or multicast messages for associated clients, it  
sends the next DTIM with a DTIM Interval value. Its clients hear the beacons and  
awaken to receive the broadcast and multicast messages.  
(Default: 1, Range: 1-255)  
Fragmentation Threshold  
The fragmentation threshold value specifies the maximum size for a packet before  
data is fragmented into multiple packets. If you experience a high packet error rate,  
you may slightly increase the Fragmentation Threshold. Setting the Fragmentation  
Threshold too low may result in poor network performance. Only minor reduction  
of the default value is recommended. In most cases, it should remain at its default  
value of 2346.  
RTS Threshold  
The RTS Threshold determines at what packet size beyond which the ready to  
send/clear to send (RTS/CTS) mechanism is invoked. Should you encounter  
inconsistent data flow, only minor reduction of the default value, 2346, is  
recommended. If a network packet is smaller than the preset RTS Threshold size,  
the RTS/CTS mechanism will not be enabled. The device sends Request to Send  
(RTS) frames to a particular receiving station and negotiates the sending of a data  
frame. After receiving an RTS, the wireless station responds with a Clear to Send  
(CTS) frame to acknowledge the right to begin transmission. The RTS Threshold  
value should remain at its default value of 2347.

Security > VPN  
A Virtual Private Network (VPN) is a connection between two endpoints in different  
networks that allows private data to be sent securely over public networks or other  
private networks. This is accomplished by creating a "VPN tunnel." A VPN tunnel  
connects the two PCs or networks and allows data to be transmitted over the  
Internet as if it were on a private network. The VPN tunnel uses IPsec to encrypt the  
data sent between the two endpoints and encapsulate the data within a normal  
Ethernet/IP frame allowing the data to pass between networks securely and  
seamlessly.  
A VPN provides a cost-effective and more secure alternative to using a private,  
dedicated, leased line for a private network. Using industry standard encryption and  
authentication techniques, an IPsec VPN creates a secure connection that operates as  
if you were directly connected to your local private network.  
For example, a VPN allows users to sit at home and connect to his/her employer's  
corporate network and receive an IP address in their private network just as though  
they were sitting in their office connected to their corporate LAN.  
Select the VPN tab to open the Security VPN page.  
Use this page to configure the VPN for your residential gateway.

To use keyword and domain blocking  
Keyword and Domain blocking allows you to restrict access to Internet sites by  
blocking access to those sites based on a word or a text string contained in the URLs  
used to access those Internet sites.  
Domain blocking allows you to restrict access to Websites based on the site's Domain  
Name. The Domain Name is the portion of the URL that precedes the familiar .COM,  
.ORG, or .GOV extension.  
Keyword blocking allows you to block access to Internet sites based on a Keyword  
or text string being present anywhere in the URL, not just in the Domain Name.  
Note: The Domain blocking feature blocks access to any Domain in the Domain List.  
It will also block Domains, any portion of which contains an exact match to entries in  
the list.  
For example, if you enter example.com as a Domain, any site that contains  
―example.com‖ will be blocked. Generally, you do not want to include ―www.‖ in a  
Domain Name since doing so limits the blocking to only the site that matches that  
Domain Name exactly. For instance, if you enter www.example.com into the list,  
only the one site that matches that name exactly will be blocked. Consequently, if  
you do not include the ―www.,‖ then all sites within and associated with  
―example.com‖ will be blocked.  
Block Access to Websites  
If you wish to block access to websites, use the Blocked Domain List or the  
Keyword List  
To use the Blocked Domain List, enter the URLs or domain names of the websites  
you wish to block.

Overview  
Most well-known Internet applications are supported by Application Layer  
Gateways (ALGs). ALGs automatically adjust the gateway firewall to allow data to  
pass without making any custom settings. We recommend that you test your  
application before making changes in this section.  
Applications & Gaming > Port Filtering  
Use this window to configure transmission control protocol (TCP) and user  
datagram protocol (UDP) port filters. These filters prevent a range of TCP/UDP  
ports from accessing the Internet. You can also prevent PCs from sending outgoing  
TCP/UDP traffic to the WAN on specific IP port numbers. This filter is not IP  
address- or MAC address- specific. The system blocks the specified port ranges for  
all PCs.  
Select the Port Filtering tab to open the Applications & Gaming Port Filtering page.

Applications & Gaming > Port Range Forwarding  
Important: The gateway normally implements a feature called Port Translation. Port  
Translation monitors what ports are actually being used by your PCs or other  
devices on your LAN. This monitoring provides an added level of security beyond  
what the firewall provides. However, there are some applications that require the  
gateway to use specific ports to connect over the Internet.  
Use Port Range Forwarding to forward ports from the public Internet to specific IP  
addresses in your local network. Select the Port Range Forwarding tab to open the  
Applications & Gaming Port Range Forwarding page.  
For the Start and End Port, select a port from the recommended 49152 - 65535 range.  
Keep in mind that ports used are program specific so check which ones the program  
requires to be forwarded. Type the port number or range in both boxes. In the IP  
Address box type the name of the computer’s IP address to which this is to apply.  
Note: Port Range Forwarding continually exposes the selected ports to the public  
Internet. This means that the gateway’s firewall is no longer active on these ports.  
The device with the forwarding IP address can be exposed to hacker attacks while  
the port range is being forwarded.

Applications & Gaming > DMZ  
Use this page to configure an IP address whose ports are directly exposed to the  
public Internet or to the Wide Area Network (WAN). Demilitarized Zone (DMZ)  
hosting is commonly referred to as "exposed host," and allows you to specify a  
recipient of WAN traffic that Network Address Translation (NAT) is unable to  
translate to a known local PC.  
A DMZ is typically used by a company that wants to host its own Internet server.  
DMZ allows one IP address to be placed on the Internet side of the gateway firewall  
while others remain protected behind the firewall.  
The DMZ allows a device to be directly accessible to Internet traffic, such as a web  
(HTTP) server, an FTP server, an SMTP (e-mail) server, and a domain name system  
(DNS) server. Select the DMZ tab to open the Applications & Gaming DMZ page.

Frequently Asked Questions  
Q. How does the residential gateway connect to my computer?  
A. The residential gateway connects to the PC using a wireless connection or the  
10/100/1000BASE-T Ethernet port on your PC. If you want to use an Ethernet  
interface, Ethernet cards available from your local PC or office supply retailer, or  
from your service provider. For best performance over an Ethernet connection, your  
PC should be equipped with a Gigabit Ethernet card.  
Q. After my residential gateway is connected, how do I access the Internet?  
A. Your local service provider becomes your Internet Service Provider (ISP). They  
offer a wide range of services including e-mail, chat, news, and information services.  
Your service provider will provide the software you will need.  
Q. Can I watch TV and surf the Internet at the same time?  
A. Absolutely! If you subscribe to cable television service, you can watch TV and  
use your residential gateway at the same time by connecting your TV and your  
residential gateway to the cable network using an optional cable signal splitter.  
Common Troubleshooting Issues  
I don't understand the front panel status indicators  
See Front Panel LED Status Indicator Functions (on page 99), for more detailed  
information on front panel LED status indicator operation and function.  
The residential gateway does not register an Ethernet connection  
Verify that your computer has an Ethernet card and that the Ethernet driver  
software is properly installed. If you purchase and install an Ethernet card,  
follow the installation instructions very carefully.  
Verify the status of the front panel status indicator lights.  
The residential gateway does not register an Ethernet connection after connecting to a hub  
If you are connecting multiple PCs to the residential gateway, you should first  
connect the modem to the uplink port of the hub using the correct crossover cable.  
The LINK LED of the hub will illuminate continuously.  
The residential gateway does not register a cable connection  
The modem works with a standard 75-ohm RF coaxial cable. If you are using a  
different cable, your residential gateway will not function properly. Contact your  
cable service provider to determine whether you are using the correct cable.  
Your NIC card or USB interface may be malfunctioning. Refer to the  
troubleshooting information in the NIC or USB documentation.

Tips for Improved Performance  
Tips for Improved Performance  
Check and Correct  
If your residential gateway does not perform as expected, the following tips may  
help. If you need further assistance, contact your service provider.  
Verify that the plug to your residential gateway AC power is properly inserted  
into an electrical outlet.  
Verify that your residential gateway AC power cord is not plugged into an  
electrical outlet that is controlled by a wall switch. If a wall switch controls the  
electrical outlet, make sure the switch is in the ON position.  
Verify that the ONLINE LED status indicator on the front panel of your  
residential gateway is illuminated.  
Verify that your cable service is active and that it supports two-way service.  
Verify that all cables are properly connected, and that you are using the correct  
cables.  
Verify that your TCP/IP is properly installed and configured if you are using the  
Ethernet connection.  
Verify that you have called your service provider and given them the serial  
number and MAC address of your residential gateway.  
If you are using a cable signal splitter so that you can connect the residential  
gateway to other devices, remove the splitter and reconnect the cables so that the  
residential gateway is connected directly to the cable input. If the residential  
gateway now functions properly, the cable signal splitter may be defective and  
may need to be replaced.  
For best performance over an Ethernet connection, your PC should be equipped  
with a Gigabit Ethernet card.
