“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).
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.
