Carrier Freq [Hz]: the frequency of the carrier signal for AM tones.
Modulation Freq [Hz]: the frequency of the modulated signal for AM tones (valid
range from 1 Hz to 128 Hz).
Signal Level [-dBm]: the level of the tone for AM tones.
AM Factor [steps of 0.02]: the amplitude modulation factor (valid range from 1 to
50. Recommended values from 10 to 25).
•
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 should differ by at least 40 Hz from one tone to other
defined tones.
For example: to configure the dial tone to 440 Hz only, define the following text:
Figure 120 Defining a Dial Tone Example
#Dial tone
[CALL PROGRESS TONE #1]
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
