• First Signal Off Time [10 msec]: 'Signal Off' period (in 10 msec units) for the first
cadence on-off cycle (for cadence tones). For burst tones, this parameter defines
the off time required after the burst tone ends and the tone detection is reported.
For continuous tones, this parameter is ignored.
• Second Signal On Time [10 msec]: 'Signal On' period (in 10 msec units) for the
second cadence on-off cycle. Can be omitted if there isn't a second cadence.
• Second Signal Off Time [10 msec]: 'Signal Off' period (in 10 msec units) for the
second cadence on-off cycle. Can be omitted if there isn't a second cadence.
• 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 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, enter the following text:
#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
