Cadence
(msec) On/Off n/n/n/n
four integer time
values in
milli-seconds;
zero value for
dial-tone
indicates
continuous tone On/off pattern of tone durations
used to denote phone ringing,
phone busy, connection
unobtainable (fast busy), dial tone
(“0” indicates continuous tone),
survivability, and re-order. Default
values differ for different
countries/regions. Although most
cadences have only two parts (an
“on” duration and an “off”
duration), some telephony
cadences have four parts. Most
cadences, then, are expressed as
two iterations of a two-part
sequence. Although this is
redundant, it is necessary to allow
for expression of 4-part cadences.
Custom

Click on the “Custom” button to
bring up the
Custom Tone Pair
Settings screen. (The “Custom”
button is active only when
“Custom” is selected in the
Country/Region field.) This screen
allows the user to specify tone pair
attributes that are not found in any
of the standard national/regional
telephony toning schemes.
