9 Configuration and Operation at the Telephone
FRITZ!Box Keypad Sequences
Many of the FRITZ!Box functions and features can be config-
ured and used over a telephone connected to a FRITZ!Box
extension. Only tone-dialing (dual-tone multifrequency =
DTMF) telephones can be used in configuration and opera-
tion. Pulse dialing telephones are not suitable.
Acknowledgment
Tone
Entries input on the telephone are confirmed with acknowl-
edgement tones (see also “Handset and Ring Patterns” on
page 113):
 Entries made correctly are confirmed with a positive
acknowledgement tone (a single tone of one second
in length).
 If the entry was not successful, because of an incor-
rect key sequence, for instance, you hear a negative
acknowledgment tone (an intermittent tone broken in-
to intervals of about 0.25 seconds).
9.1 Configuring at the Telephone
Saving New Settings
In this section, saving refers to all current settings made in
the FRITZ!Box. It is not necessary to save the configuration
immediately after every change. You may first configure all
of your settings as desired, and then save them permanent-
ly.
The telephone network features can be used only if they
are supported by your telephone network carrier and en-
abled on your telephone line.
Permanent saving cannot be reversed. However, you can
reprogram different settings or restore the FRITZ!Box to its
factory settings.
