Engineering:ToneScript

ToneScript is a description syntax for the characteristics of call-progress tones. A call progress tone is a pattern of audible tones played to the caller in a telephone call, conveying the status of the call. ToneScript describes the pattern of frequency, cadence, and level of the signal. Many Internet telephony devices support configuration options for users to customize the tones, but standard patterns are provided for various telephone administrations. ToneScript is used in Sipura, Linksys and Cisco family of IP telephony products.

Format

• A ToneScript syntax may have at most 120 characters.
• A calling tone may use up to 6 frequency components [math]\displaystyle{ n_k }[/math] where [math]\displaystyle{ 1 \lt = k \lt = 6 }[/math]
• A cadence section [math]\displaystyle{ Z_i }[/math] indicates its Duration [math]\displaystyle{ D_i }[/math] followed by up to 6 subsections [math]\displaystyle{ ZZ_{i,j} }[/math] in parentheses. A subsection consists of an ON duration (* for always on), an OFF duration and the list of frequency components [math]\displaystyle{ f_{i,j} }[/math] used in that subsection.

[math]\displaystyle{ f_{i,j} := n_1[+n_2[+n_3[+n_4[+n_5[+n_6]]]]] }[/math]

[math]\displaystyle{ ZZ_{i,j} := on_{i,j}/off_{i,j}/f_{i,j} }[/math]

[math]\displaystyle{ Z_i := D_i([ZZ_{i,1} [,ZZ_{i,2} [,ZZ_{i,3} [,ZZ_{i,4} [,ZZ_{i,5} [,ZZ_{i,6}]]]]]) }[/math]

• A FreqScript is a sequence of frequencies [math]\displaystyle{ F_i }[/math] in hertz and their corresponding levels [math]\displaystyle{ L_i }[/math] in dBm

  [math]\displaystyle{ FreqScript:=F_1 }[/math]@[math]\displaystyle{ L_1[,F_2 }[/math]@[math]\displaystyle{ L_2] }[/math]

• A Tone Script has a frequency specification and one or two cadence sections.

[math]\displaystyle{ ToneScript:=FreqScript;Z_1[;Z_2] }[/math]

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.
