Frequently Asked Questions 
Q.  What if I don't subscribe to telephone service from my cable operator, can I 
still use the cable modem to make and receive phone calls?
 
A.  No. Telephone service is enabled for each telephone port on the cable modem by 
the cable telephony service provider. Contact your cable telephony service provider 
to get telephone service through the cable modem. 
Q.  How do I arrange for installation? 
A.  Professional installation from your cable telephony service provider may be 
provided. A professional installer can connect the telephone service to your existing 
telephone wiring in your home or install new wiring if needed. Professional 
installation also ensures proper cable connection to the modem and to your PC, and 
ensures proper configuration of all hardware and software settings. Contact your 
cable telephony service provider for more information about installation. 
Q.  Can I use my existing phone number with the cable modem? 
A.  Telephone numbers are portable in some areas. Contact your telephone service 
provider for more information about using an existing telephone number. 
Q.  Do I automatically receive high-speed Internet service with the cable modem? 
A.  Your cable modem may be used to provide telephone service, high-speed 
Internet service, or both services. Your cable service provider enables Internet 
service. Contact your cable service provider for more information if you are not 
currently subscribing to Internet service. 
Q.  How many telephones can I connect? 
A.  The RJ-11 telephone-style connectors on the cable modem can each provide 
telephone service to multiple telephones, fax machines, and analog modems. The 
maximum number of telephone devices connected to each RJ-11 port is limited by 
the total Ringing Load of the telephone devices that are connected. Many telephone 
devices are marked with a Ringer Equivalent Number (REN). Each telephone port 
on the cable modem can support up to a 5 REN load. The sum of the REN load on all 
of the telephone devices attached to each port must not exceed 5 REN.
