Telephone or Fax Connection
When properly connected, most telephony devices can be used with the cable modem just as
with conventional telephone service. To make a normal telephone call, pick up the handset, wait
for a dial tone, and then dial the desired number. For services such as call waiting, use the hook
switch (or FLASH button) to change calls. The following procedures describe some of the
possible connection schemes for using telephony devices with the cable modem.
1. Connect a standard phone line cord directly from the phone (fax machine, answering
machine, caller ID box, etc.) to one of the LINE jacks on the cable modem (see Fig. 5).
2. If there is a phone line in your home which is NOT connected to another telephone service
provider, connect a standard phone line cord from a jack on this line to one of the LINE jacks
of the cable modem. Connect a standard phone line cord directly from the phone (fax
machine, answering machine, caller ID box, etc.) to one of the other jacks in the house that
uses that line.
3. If you have a multi-line telephone, connect a standard phone line cord (not an RJ-14 type line
cord) from the phone to the LINE jacks on the cable modem. (Other phones can be added to
each line by using standard phone line splitters.
