6The analog port (SmartLine D721 only)

The SmartLine D721 ISDN telephone has an internal analog interface. This means that you can connect an analog terminal (a telephone, an answering machine or a fax machine) to this socket. The ISDN telephone performs the conversion to the digital ISDN network as well as the "switching functions" such as "…on what number (MSN) does the ISDN

telephone ring and on what number does the analog

terminal ring?". If the analog terminal is a telephone, free internal calls with the ISDN telephone are possi- ble. Telephone number display of incoming calls for

the analog terminal is supported; the ISDN telephone communicates the date, time and telephone number. Please only use the included adapter cable for con-

nection. All special and set up functions are only available if the analog termi- nal is set to DTMF (dual tone multi-frequency dialling) and the flash key.
