What if I Do Not Subscribe to Cable TV?
If cable TV is available in your area, data service may be made available with or
without subscribing to cable TV service. Contact your local service provider for
complete information on cable services, including high-speed Internet access.
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, your PC needs Ethernet cards. These cards are
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 email, chat, news, and information services. Your
service provider will provide the software that 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.
