“Regional Parameter” Definitions (cont’d)
Field Name Values Description
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), and dial
tone (“0” indicates continuous
tone). 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.
Pulse
Generation
Ratio
pair of integer
values in
milliseconds;
60/40 or 67/33
Ratio of “make” duration versus
“break” duration when a tone
pulse is generated. 60/40 applies
to US telephony; 67/33 applies
internationally (note, however, that
US telephony standards are used in
certain regions/nations outside the
US).

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.
