10 Configuration and Operation by
Telephone
Many of the FRITZ!Box Fon functions and features can be
configured and used over a telephone connected to a
FRITZ!Box Fon extension. Only tone-dialing (dual-tone multi-
frequency = DTMF) telephones can be used in configuration
and operation. Pulse dialing telephones are not suitable.
The telephone network features can be used only if they are
supported by your telephone network carrier and enabled on
your telephone line.
Entries input on the telephone are confirmed with an ac-
knowledgement tone. Entries made correctly are confirmed
with a positive acknowledgement tone (a single tone of one
second in length). An error, such as an incorrect key se-
quence, is indicated by a failure tone, an intermittent tone at
intervals of about 0.25 seconds.
Designation of the Functions and Features
Functions and features whose application has direct effects
on the connection are marked with icons. The icons indicate
the connection types with which the function or feature can
be used or applied.
Functions and features that have no effect on the connection
are not marked.
An overview of all of the icons used in this manual is pre-
sented in the section “Symbols and Highlighting” from
page 5 of this manual.
