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.

Field Description
DTIM Interval
The Delivery Traffic Indication Message (DTIM) indicates the interval between
Broadcasts/Mul tica st 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.

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

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.

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 102), 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.
