Ring Pattern Detec­
tion (DRPD) feature
Some phone companies offer a distinctive ring pattern (DRP) service whereby they
assign two or more telephone numbers with distinctive ring patterns to a single tele­
phone line. If your phone company offers such a service, you can have both a fax
number(s) and a telephone number(s) for your FAXPHONE using only one telephone
line.
Your FAXPHONE will automatically detect incoming calls. Based on the distinctive
ring pattern, the FAXPHONE knows if the call is from a fax machine trying to send a
document or from a telephone trying to make a voice call.
Use the information in this section to set up the FAXPHONE for use with a DRP
service.
This feature is called Distinctive Ring Pattern Detection (DRPD).
Eor more details on the DRP service, contact your local telephone company. (Your
telephone company may have a different name for this service. Also, this service may
not be offered in all areas.)
