How Do I Select and Place Home Phoneline Networking Devices?
Home phoneline networking is also known as HPNA. HPNA service allows all the components of a home network
to interact over the home’s existing telephone wiring without disturbing the existing voice or fax services. Home
phoneline networking (HPNA) processes, manages, transports and stores information, and enables the devices in
a home network such as telephones, fax machines, desktop computers, laptops, printers, scanners and Web
cameras to connect and integrate over a home’s telephone wiring topology.
This section does not provide all of the information required to install specific HPNA devices, but instead
provides a general overview. For specifics, please consult the documentation provided by the manufacturer of
your HPNA device(s).
How Do I Select HPNA Devices?
You can use a large variety of HPNA devices with your cable modem gateway.
These include NIC cards, USB adapters, routers, and bridges. On the HPNA
network, all devices impact the characteristics of the network because each
device requires a certain amount of bandwidth to operate. Contact your cable
service provider or consult the documentation for your HPNA device for more
information on selecting the appropriate HPNA devices for your home or office
purposes.
Where is the Best Location for My HPNA Devices?
You should work with your cable service provider to choose the best location for
your HPNA devices. Consider these recommendations:
•
Not all homes are wired the same. It is very important to ensure that the wall
telephone jack is wired and functioning correctly to support a HPNA-certified
device. You can test your telephone wiring using a simple phone line tester
available at a variety of retailers.
•
•
All HPNA devices must be connected to a single telephone line. Some home
have more than one telephone line for a fax machine or a second voice line.
The phone line used does not have to be an “active” telephone line with a
telephone number. A spare telephone wiring pair may be used, but all HPNA
devices must be connected to the same telephone wiring pair.
Now that you have selected a location for your HPNA network devices, the next
step is to place and connect your HPNA network devices. Go to How Do I

dynamic function. In other words, the ports are not
held open, and the ports close if no outgoing data
is detected on the selected ports for a period of 10
minutes.
DMZ Host
(Demilitarized Zone)
Use this page to configure an IP address that is
visible to the wide area network (WAN). DMZ
hosting is commonly referred to as “exposed host,”
and allows you to specify the “default” recipient of
WAN traffic that Network Address Translation
(NAT) is unable to translate to a known local PC.
A DMZ is used by a company that wants to host its
own Internet services without sacrificing
unauthorized access to its private network. DMZ
allows one IP address to be unprotected while
others remain protected. The DMZ is located
between the Internet and an internal network’s line
of defense that is a combination of firewalls and
bastion hosts.
Typically, the DMZ contains devices accessible to
Internet traffic, such as Web (HTTP) servers, FTP
servers, SMTP (e-mail) servers, and domain name
system (DNS) servers.

the box in the Enable field.
Click Apply to apply and save your new port forwarding settings.
Configuring TCP/UDP Port Triggers
Use the Setup Advanced Settings – Port Triggers page to configure TCP/UDP
port triggers. Port triggering is similar to port forwarding but is dynamic. In other
words, the system does not hold the ports open indefinitely. For example, when
the cable modem gateway detects outgoing data on a specific IP port number set
in the “Trigger Range,” the resulting ports set in the “Target Range” open for
incoming data. If the system detects no outgoing traffic on the “Trigger Range”
ports for a period of 10 minutes, the “Target Range” ports close. This is a safer
method for opening specific ports for special applications, such as, video
conferencing programs, interactive gaming, and file transfer in chat programs.
This is safe because the ports are dynamically triggered and not held open
continuously, or erroneously left open by the router administrator. Therefore,
these ports are not exposed and vulnerable for potential hackers to discover.
If you are not familiar with the advanced settings detailed in this section,
contact your cable service provider before you attempt to change any of the
cable modem gateway default advanced port triggers settings.

matching pre-configured WEP keys.
•
Shared Key—During shared key authentication, the
WAP sends an unencrypted challenge text string to
any device attempting to communicate with the
WAP. The device requesting authentication
encrypts the challenge text and sends it back to the
WAP. If the challenge text is encrypted correctly,
the access point allows the requesting device to
authenticate. Both the encrypted challenge and the
encrypted challenge response can be monitored,
however, which leaves the WAP open to attack
from intruders. Therefore, shared key
authentication can be less secure than open
authentication.

Frequently Asked Questions
Internet Installation
Q. What if I don’t subscribe to cable TV?
A. If cable TV is available in your area, high-speed data service may be made
available with or without subscribing to cable TV service. Contact your local cable
service provider for complete information on available broadband services,
including high-speed Internet access.
Q. How do I arrange for installation?
A. Professional installation from your cable service provider may be provided.
Professional installation also ensures proper cable connection to the cable
modem gateway and to your device(s), and ensures proper configuration of all
hardware and software settings. Contact your cable service provider for more
information about installation.
Q. How does the WebSTAR Cable Modem Gateway connect to my computer and
other devices?
A. The cable modem gateway connects to your computer and other devices
through the USB port, the 10/100BaseT Ethernet ports, an optional wireless
connection, or the optional HPNA port. If your computer(s) or other devices are
not equipped with the appropriate networking interfaces, contact your cable
service provider. These items may often be upgraded or purchased from your
local computer or office supply retailer, or from your cable service provider.
Q. Once my cable modem gateway is connected, how do I access the Internet?
A. Your local cable service provider becomes your Internet Service Provider
(ISP), offering a wide range of services including e-mail, chat, news, and
information services. Your cable service provider also supplies 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 cable modem gateway at the same time by connecting your TV and
your cable modem gateway to the cable network using an optional cable signal
splitter.
Q. How many devices can I connect to the cable modem gateway?
A. A single cable modem gateway is able to support up to 253 devices. However,
under normal circumstances, the number of devices connected should be a
much lower number. Contact your cable service provider for more information on
the maximum number of devices to connect to the cable modem gateway in
order to maintain optimal network performance.

Home Phoneline Networking (Optional)
Q. How do I arrange for installation?
A. Professional installation from your cable service provider may be provided. A
professional installer can connect the HPNA port to your existing telephone
wiring in your home, or install new wiring if needed. Professional installation also
ensures proper cable connection to the cable modem gateway and to your home
networking devices, and ensures proper configuration of all hardware and
software settings. Contact your cable telephone service provider for more
information about installation.
Q. Can I use my telephone, modem, fax, and answering machines with an HPNA
network?
A. Yes! Standard telephones, dial up analog modems, faxes, and answering
machines can be used simultaneously with HPNA because, even though they
exist on the same telephone wires, they occupy different frequency bands.
Q. What is the maximum achievable distance between nodes for an HPNA
network?
A. HPNA is designed to reach up to 1000 feet (300 meters) between any two
adapters. If the network has more than two HPNA adapters, all of the adapters
must be within 1000 feet of each other. The actual distance may be lesser or
greater depending on the type of wire, noise conditions, and topology of the
telephone wiring in your home.
Q. Do I automatically receive high-speed Internet service with the cable modem
gateway?
A. Your cable modem gateway may be used for HPNA service, high-speed
Internet service, or both services. Your cable service provider enables Internet
service. Contact your cable service provider for more information if you are not
currently subscribing to Internet service.
Q. Why do I hear a faint high-pitched tone on the phone line when I am using the
phone?
A. Occasionally an HPNA network creates a faint high-pitched tone on the
phone line. You can correct this situation by purchasing and installing a DSL filter
to the phone line that goes into your telephone set.
Q. Does the phone line need to be active to create an HPNA network?
A. No! An HPNA network can be created on an inactive (no phone number)
telephone line as well as an active (has a phone number) telephone line. An
HPNA network can be created on spare telephone wiring or even on an available
pair of a CAT-5 Ethernet cable.
The HPNA devices use the middle two conductors of the RJ-11 telephone
jack.
Q. Can I surf the Internet and make telephone calls at the same time?
A. Absolutely! All HPNA devices use different frequencies. Internet surfing and
other data services do not affect the quality of your telephone calls. You can
make telephone calls and surf the net at the same time.

Having Difficulty?
Having Difficulty?
If your cable modem gateway does not operate as expected, the following troubleshooting tips may help. If you
need further assistance, contact your cable service provider.
My cable modem gateway does not register a cable connection.
•
The cable modem gateway works with a standard, 75-ohm, RF coaxial cable.
If you are using a different cable, your cable modem gateway will not function
properly. Contact your cable service provider to determine whether you are
using the correct cable.
•
•
Verify that the plug to your cable modem gateway AC adapter is properly
inserted into an electrical outlet.
Verify that your cable modem gateway AC adapter 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 Power and Cable indicators on the front panel of your cable
modem are illuminated.
•
•
•
Verify that all cables are properly connected.
Verify that your cable service is active and that it supports two-way service.
Verify that you have called your cable service provider and given them the
serial number and MAC address of your cable modem gateway.
•
If you are using a cable signal splitter so that you can connect the cable
modem gateway to other devices, remove the splitter and reconnect the
cables so that the cable modem gateway is connected directly to the cable
input. If the cable modem gateway now functions properly, the cable signal
splitter may be defective and may need to be replaced.
There is no dial tone when I lift the telephone handset.
•
You may be using the wrong phone cable to connect the HPNA port on the
cable modem gateway to your wall telephone jack. Try a different phone
cable.
•
•
There may be a problem with your home telephone wiring. A professional
may need to diagnose and repair a problem with your telephone wiring.
There may be a problem with your telephone set. Use a different telephone
set and listen to hear dial tone.
