What's In the Carton?
What's In the Carton?
When you receive your wireless residential gateway, you should check the
equipment and accessories to verify that each item is in the carton and that each item
is undamaged. The carton contains the following items:
One of the DOCSIS Residential
Gateway models:
One power adapter (models
requiring external power supply)
One Ethernet cable (CAT5/RJ-45)
One CD-ROM
If any of these items are missing or damaged, please contact your service provider
for assistance.
Notes:
 
You will need an optional cable signal splitter and additional standard RF
coaxial cables if you want to connect a VCR, a Digital Home Communications
Terminal (DHCT) or a set-top converter, or a TV to the same cable connection as
your wireless residential gateway.
 
Cables and other equipment needed for telephone service must be purchased
separately. Contact your service provider to inquire about the equipment and
cables you need for telephone service.

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.
