6.4.2.2.4 Modifying the Call Progress Tones File
Customers are supplied with modifiable Call Progress Tone auxiliary source files (with ini
file extension) and non-modifiable Call Progress Tone dat binary files in the software
package under Tones\.
Only the binary dat file can be sent to the MG 3200.
In the auxiliary source file, customers can modify Call Progress Tone levels, Call Progress
Tone frequencies to be detected/generated by the MG 3200, to suit customer-specific
requirements.
call_progress_defaults.dat. Note that the word 'tones' is defined in the Call Progress Tone
ini file name, to differentiate it from the MG 3200's ini file.
The default call progress tones configuration is found on call_progress_defaults.ini file. To
change one of the tones, edit the default call progress txt file.
For example: to change the dial tone to 440 Hz only, replace the #Dial tone section in the
table below with the following text:
#Dial tone
[CALL PROGRESS TONE #1]
Tone Type=1
Tone Form = 1
Low Freq [Hz]=440
High Freq [Hz]=0
Low Freq Level [-dBm]=10 (-10dBm)
High Freq Level [-dBm]=0
First Signal On Time [10msec]=300; the dial tone is detected after 3 sec
Users can specify several tones of the same type using Tone Type definition. These
additional tones are used only for tone detection. Generation of specific tone is according
to the first definition of the specific tone. For example, the user can define an additional dial
tone by appending the second dial tone definition lines to the tone ini file. The MG 3200
reports dial tone detection if either one of the two tones is detected.
To modify these ini files and send the dat file to the MG 3200, take
these 4 steps:
1. Open the CPT ini file (it opens in Notepad or in a customer-defined text file editor.)
2. Modify the file in the text file editor according to your specific requirements.
3. Save your modifications and close the file.
4. Convert the file with the DConversion Utility into a binary dat file (refer to "Converting a
Modified CPT ini File to a dat File with the Download Conversion Utility" below).
