•
Third Signal On Time [10 msec]: 'Signal On' period (in 10 msec units) for the
third cadence on-off cycle. Can be omitted if there isn't a third cadence.
•
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
41.1.2 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.
