Telephone Service
You will need to establish a telephone account with your local service provider to
use your cable modem for telephone service.
When you contact your service provider, you may be able to transfer your existing
telephone numbers. If not, then your cable telephony service provider will assign a
new telephone number to enable your voice service(s). Discuss these options with
your telephony service provider.
Where Is the Best Location for My Cable Modem?
The ideal location for your cable modem 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 cable modem. Read this user
guide thoroughly before you decide where to place your cable modem.
Consider these recommendations:
Choose a location close to your computer if you will also use the cable modem
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 so that there is plenty of room to guide the cables away from
the cable modem without straining or crimping them.
Choose a location that allows adequate ventilation around the cable modem.
Choose a location for the cable modem that is adjacent to your telephone
equipment if you plan on connecting your phone directly to the cable modem.
Note: If you are using the cable modem to provide service to several telephones,
a professional installer can connect the cable modem to your existing home
telephone wiring.
Install the Battery (Optional)
Your cable modem may include one rechargeable Lithium-Ion battery to provide
stand-by operation in the event of an AC power failure. We recommend that you
install the battery before mounting the cable modem to a wall (if you decide to do
so) and before installing the cable modem in your home.
It is possible to use the cable modem without the battery. However, if you choose to
operate the cable modem without a battery, you will not have telephone service
during a power outage.
For information on battery maintenance, refer to Maintaining the Battery (on page
27).
