How Do I Connect the Cable Modem for Internet and Telephone Service?
Important: When using a USB connection, you need to install USB drivers on
your PC. For assistance, go to Installing USB Drivers (on page 26).
Note: You can connect two separate PCs to the cable modem at the same time by
connecting one PC to the ETHERNET port and one PC to the USB port.
However, do not connect your PC to both the ETHERNET and USB ports at the
same time.
5 Connect one end of a telephone jumper cable (not included) to a telephone outlet
in your home or to a telephone or fax machine. Then connect the other end of the
jumper cable to the appropriate RJ-11 TELEPHONE port on the back of the cable
modem. The telephone ports are light gray and are labeled 1/2 and 2 or 1 and 2
depending on the region of the world the cable modem is used.
Notes:
– Make sure to connect your telephone service to the correct RJ-11 port. For
single line telephone service, connect to port 1/2 or 1.
– In North America, cable modems have multi-line capability on the RJ-11
telephone port labeled 1/2. Line 1 is on pins 3 and 4 of port 1/2, and
Line 2 is supported on pins 2 and 5. In Europe, cable modems support
only one line per port. Line 1 is on port 1 and line 2 is on port 2.
– Telephones that require electrical connectors other than RJ-11 may
require an external adapter (sold separately).
6 Locate the AC power cord provided with your cable modem. Insert one end of
the power cord into the AC connector on the back of the cable modem. Then,
plug the AC power cord into an AC outlet to power-up the cable modem. The
cable modem will perform an automatic search to locate and sign on to the
broadband data network. This process may take up to 2-5 minutes. The modem
will be ready for use when the POWER, DS, US and ONLINE LEDs on the front
panel of the cable modem stop blinking and remain on continuously.
7 Plug in and power on your PC and other home network devices. The LINK LED
on the cable modem corresponding to the connected devices should be on or
blinking.
8 Once the cable modem is online, most Internet devices will have immediate
Internet access.
Note: If your PC does not have Internet access, refer to Frequently Asked
Questions (on page 28) for information on how to configure your PC for TCP/IP.
For Internet devices other than PCs, refer to the DHCP or IP Address
configuration section of the User Guide or Operations Manual for those devices.
