How Do I Arrange for Installation?
Call your service provider to inquire about professional installation. A professional
installation ensures proper cable connection to the residential gateway and to your
PC, and it ensures the proper configuration of all hardware and software settings.
Contact your service provider for more information about installation.
How Does the Wireless Residential Voice Gateway Connect to My Computer?
The residential gateway connects to the 10/100/1000BASE-T Ethernet port on your
PC. To use the 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.
After My Wireless Residential Voice Gateway Is Connected, How Do I Access the
Internet?
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.
Can I Watch TV and Surf the Internet at the Same Time?
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.
Can I Use my Existing Phone Number with the Wireless Residential Voice
Gateway?
Telephone numbers are portable in some areas. Contact your telephone service
provider for more information about using an existing telephone number.
How Many Telephones Can I Connect?
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.

Common Troubleshooting Issues
This section describes common problems and offers solutions.
I don't understand the front panel status indicators
See
Operation of Front Panel Indicators
(on page 21), for more detailed information
on front panel LED status indicator operation and function.
The Wireless Residential Voice Gateway does not register an Ethernet
connection
Try one of the following solutions:
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 Wireless Residential Voice 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 residential gateway to the uplink port of the hub using the correct
crossover cable. The LINK LED of the hub will illuminate continuously.
The Wireless Residential Voice Gateway does not register a cable connection
The residential gateway 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 service provider to determine whether you are using the correct cable.
There is no dial tone when I lift the handset
Try the following solutions if you cannot hear a dial tone:
Your telephone wiring may be connected to the wrong RJ-11 port on the
residential gateway. The residential gateway has two telephone ports. Verify that
you are connected to the correct telephone port.
There may be a problem with your telephone set. Use a different telephone set
and listen to hear dial tone.

There may be a problem with your home telephone wiring. Use a telephone and
connect directly to the same RJ-11 port on the back of the unit. If the dial tone is
working here but does not work at other locations in the home, a professional
may need to diagnose and repair a problem with your telephone wiring.
Verify that the telephone company has removed the previous telephone service
from your home telephone wiring.
Your telephone service may not be enabled from your cable telephony service
provider. Contact your cable telephony service provider for more information.
