ToneScript

ToneScript is a mini script used to describe the characteristics of Call progress tones

Description

A call progress tone is a pattern of tones made audible to the caller, conveying some status about the call. Despite its name, a call-progress tone could be a sequence of tones, that may be repeated or emitted just once. ToneScript is a mini script that describes the pattern of frequency, cadence and level of tones in call progress tones. Many internet telephony devices using more sophisticated operating systems permit users to customize the tones. Customarily the devices are preset with the standard tones defined and regulated by standards bodies in a given region. ToneScript is used in Sipura, Linksys and Cisco family of IP telephony products.

Format

ToneScript may have at most 120 characters.
A calling tone may use up to 6 frequency components $n_{k}$ where $1<=k<=6$
A cadence section $Z_{i}$ indicates its Duration $D_{i}$ followed by up to 6 subsections $ZZ_{i,j}$ in parenthesis. A subsection consists of an ON duration (* for always on), an OFF duration and the list of frequency components $f_{i,j}$ used in that subsection.

f_{i,j}:=n_{1}[+n_{2}[+n_{3}[+n_{4}[+n_{5}[+n_{6}]]]]]

ZZ_{i,j}:=on_{i,j}/off_{i,j}/f_{i,j}

Z_{i}:=D_{i}([ZZ_{i,1}[,ZZ_{i,2}[,ZZ_{i,3}[,ZZ_{i,4}[,ZZ_{i,5}[,ZZ_{i,6}]]]]])

A FreqScript is a sequence of frequencies $F_{i}$ in hertz and their corresponding levels $L_{i}$ in dBm
$FreqScript:=F_{1}$ @ $L_{1}[,F_{2}$ @ $L_{2}]$
A Tone Script has a frequency specification and one or two cadence sections.

ToneScript:=FreqScript;Z_{1}[;Z_{2}]

Examples

350@-19,440@-19;10(*/0/1+2)
Contains 2 frequency components
Frequency component 1 is 350 Hz at -19 dBm

Frequency component 2 is 440 Hz at -19 dBm

There is 1 Cadence Section
In this section, The duration is 10 seconds and the tone has only 1 subsections
In the only subsection the tone is always on, off for 0 seconds, and composed of both the Frequency components 1 and 2 (350 Hz and 440 Hz)
350@-19,440@-19;2(.2/.2/1+2);10(*/0/1+2)
Contains 2 frequency components
Frequency component 1 is 350 Hz at -19 dBm

Frequency component 2 is 440 Hz at -19 dBm

There are two Cadence Sections
In the first Cadence Section, The duration is 2 seconds and the tone has only 1 subsections
In the only subsection the tone is on for 0.2 seconds, off for 0.2 seconds, and composed of both the Frequency components 1 and 2 (350 Hz and 440 Hz)

In the second Cadence Section, The duration is 10 seconds and again the tone has only 1 subsections
In the only subsection the tone is always on, off for 0 seconds, and composed of both the Frequency components 1 and 2 (350 Hz and 440 Hz)
349@-21,392@-21,440@-21,466@-21,523@-24,540@-24;2.1(.6/0/3,.2/0/2,.7/0/1,.2/0/2,.2/0/3,.3/0/4);30(*/0/5+6)
Christmas theme dialtone (seven notes of ′The First Noel′ then continuous dialtone for 30 seconds)

Contains 6 frequency components
Frequency components are 349, 392, 440, 466, 523 and 540 Hz (five musical notes) plus a beat frequency tone mix to give a warble dialtone beat thereafter.

There are two Cadence Sections
In the first Cadence Section, the total duration is 2.1 seconds and the tone has 6 subsections with timing set for music.
The tones are turned on and off to give the ′notes′ of the familiar Christmas carol.

In the second Cadence Section, the duration is 30 seconds. It combines tones 5 and 6 to give the last note and the familiar 17 Hz beat of dialtone.
392@-19,440@-19,494@-19,294@-19,457@-19;3.5(.7/0/4,.8/0/1,.6/0/1,.5/0/3,.7/0/2,.2/0/1);30(*/0/2+5)
New Year theme dialtone (four notes of ′Auld Lang Syne′ then continuous dialtone for 30 seconds)

Contains 5 frequency components
Frequency components are 392, 440, 494, 292 and 457 Hz (four musical notes) plus a beat frequency tone mix to give a warble dialtone beat thereafter.

There are two Cadence Sections
In the first Cadence Section, the total duration is 3.5 seconds and the tone has 6 subsections with timing set for music.
The tones are turned on and off to give the ′notes′ of the familiar New Year's Eve tune.

In the second Cadence Section, the duration is 30 seconds. It combines tones 4 and 5 to give the last note in the familiar 17 Hz beat of dialtone.
