• 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
31.1.1.1 Distinctive Ringing
Distinctive Ringing is applicable only to FXS interfaces. Using the Distinctive Ringing
section of the Call Progress Tones auxiliary file, you can create up to 16 Distinctive Ringing
patterns. Each ringing pattern configures the ringing tone frequency and up to four ringing
cadences. The same ringing frequency is used for all the ringing pattern cadences. The
ringing frequency can be configured in the range of 10 to 200 Hz with a 5 Hz resolution.
Each of the ringing pattern cadences is specified by the following parameters:
Burst Ring On Time: Configures the cadence to be a burst cadence in the entire
ringing pattern. The burst relates to On time and the Off time of the same cadence. It
must appear between 'First/Second/Third/Fourth' string and the 'Ring On/Off Time'
This cadence rings once during the ringing pattern. Otherwise, the cadence is
interpreted as cyclic: it repeats for every ringing cycle.
