n DRPD (Distinctive Ring Pattern Detection) MODE - Distinctive Ring is a telephone company service which enables a user to use a single telephone line to answer several different telephone numbers. The particular number someone uses to call you is identified by different 1 ringing patterns, which consist of various combinations of long and short ringing sounds. This feature is often used by answering services who answer telephones for many different clients. They need to know which number someone is calling on to properly answer the phone. Using the Distinctive Ring Pattern Detection feature, your fax machine can "learn" the ring pattern you designate to be answered as a fax. Unless you change it, this ringing pattern will continue to be recognized and answered as a fax call. All other ringing patterns will be forwarded to the extension telephone or answering machine plugged into the EXT. LINE jack. Note: Before using the Distinctive Ring Pattern Detection option, Distinctive Ring service must be installed on your telephone line by the telephone company. To set up Distinctive Ring Pattern Detection, you will need another telephone line at your location, or someone available to dial your FAX number from outside. System Setup 1-53
