• Third Signal Off Time [10 msec]: 'Signal Off' period (in 10 msec units) for the
third cadence on-off cycle. Can be omitted if there isn't a third cadence.
• Fourth Signal On Time [10 msec]: 'Signal On' period (in 10 msec units) for the
fourth cadence on-off cycle. Can be omitted if there isn't a fourth cadence.
• Fourth Signal Off Time [10 msec]: 'Signal Off' period (in 10 msec units) for the
fourth cadence on-off cycle. Can be omitted if there isn't a fourth cadence.
• Carrier Freq [Hz]: Frequency of the carrier signal for AM tones.
• Modulation Freq [Hz]: Frequency of the modulated signal for AM tones (valid
range from 1 to 128 Hz).
• Signal Level [-dBm]: Level of the tone for AM tones.
• AM Factor [steps of 0.02]: Amplitude modulation factor (valid range from 1 to
50). Recommended values from 10 to 25.
Notes:
• When the same frequency is used for a continuous tone and a cadence tone, the
'Signal On Time' parameter of the continuous tone must have a value that is
greater than the 'Signal On Time' parameter of the cadence tone. Otherwise, the
continuous tone is detected instead of the cadence tone.
• The tones frequency must differ by at least 40 Hz between defined tones.
For example, to configure the dial tone to 440 Hz only, enter the following text:
[NUMBER OF CALL PROGRESS TONES]
Number of Call Progress Tones=1
#Dial Tone
[CALL PROGRESS TONE #0]
Tone Type=1
Tone Form =1 (continuous)
Low Freq [Hz]=440
High Freq [Hz]=0
Low Freq Level [-dBm]=10 (-10 dBm)
High Freq Level [-dBm]=32 (use 32 only if a single tone is
required)
First Signal On Time [10msec]=300; the dial tone is detected after
3 sec
First Signal Off Time [10msec]=0
Second Signal On Time [10msec]=0
Second Signal Off Time [10msec]=0
33.1.2 Prerecorded Tones File
The CPT file mechanism has several limitations such as a limited number of predefined
tones and a limited number of frequency integrations in one tone. To overcome these
limitations and provide tone generation capability that is more flexible, the Prerecorded
Tones (PRT) file can be used. If a specific prerecorded tone exists in the PRT file, it takes
precedence over the same tone that exists in the CPT file and is played instead of it.
Note:
The PRT are used only for generation of tones. Detection of tones is
performed according to the CPT file.
