How Do I Connect the Cable Modem for Internet and Telephone Service?
Connecting the Cable Modem for High-Speed Data and Telephone
Service
The following installation procedure ensures proper setup and configuration for the
cable modem.
1 Choose an appropriate and safe location to install the cable modem (close to a
power source, an active cable connection, your PC—if using high-speed Internet,
and your telephone lines—if using VoIP).
WARNING:
To avoid personal injury, follow the installation instructions in the exact
order shown.
To prevent possible damage to equipment, disconnect any other telephone
service before connecting your cable modem to the same wires.
Hazardous electrical voltages can exist on the telephone ports on the cable
modem and can be present on any connected wiring including Ethernet
wiring, telephone wiring and coax cable.
Telephone wiring and connections must be properly insulated to prevent
electrical shock.
Telephone connections to an installed home telephone wiring network
must be done by a qualified installer. The cable telephone service
provider may offer professional installation and connection to the home
telephone wiring network. A fee may be charged for this service.
Wiring and connections must be properly insulated to prevent electrical
shock.
Disconnect power from the cable modem before attempting to connect to
any device.
2 Power off your PC and other networking device; then, unplug them from the
power source.
3 Connect the active RF coaxial cable from your service provider to the coax
connector labeled CABLE on the back of the cable modem.
Note: To connect a TV, DHCT, set-top, or VCR from the same cable connection,
you will need to install a cable signal splitter (not included). Always check with
your service provider before using a splitter as a splitter may degrade the signal.
