2. Click the Browse button corresponding to the file type that you want to load, navigate
to the folder in which the file is located, and then click Open ; the name and path of the
file appear in the field next to the Browse button.
3. Click the Load File button corresponding to the file you want to load.
4. Repeat steps 2 through 3 for each file you want to load.
5. Save the loaded auxiliary files to flash memory, see 'Saving Configuration' on page
520 and reset the device (if you have loaded a Call Progress Tones file), see
'Resetting the Device' on page 517 .
You can also load auxiliary files using an ini file that is loaded to the device with BootP.
Each auxiliary file has a specific ini file parameter that specifies the name of the auxiliary
file that you want to load to the device with the ini file. For a description of these ini file
parameters, see Auxiliary and Configuration Files Parameters.

To load auxiliary files using an ini file:
1. In the ini file, define the auxiliary files to be loaded to the device. You can also define
in the ini file whether the loaded files must be stored in the non-volatile memory so
that the TFTP process is not required every time the device boots up.
2. Save the auxiliary files and the ini file in the same directory on your local PC.
3. Invoke a BootP/TFTP session; the ini and associated auxiliary files are loaded to the
device.
41.1.1 Call Progress Tones File
The Call Progress Tones (CPT) auxiliary file includes the definitions of the Call Progress
Tones (levels and frequencies) that are detected / generated by the device.
You can use one of the supplied auxiliary files (.dat file format) or create your own file. To
create your own file, it's recommended to modify the supplied usa_tone.ini file (in any
standard text editor) to suit your specific requirements and then convert the modified ini file
into binary format, using AudioCodes DConvert utility. For a description on converting a
CPT
ini file into a binary dat file, refer to the DConvert Utility User's Guide .
Note: Only the dat file format can be loaded to the device.
You can create up to 32 different Call Progress Tones, each with frequency and format
attributes. The frequency attribute can be single or dual-frequency (in the range of 300 to
1980 Hz) or an Amplitude Modulated (AM). Up to 64 different frequencies are supported.
Only eight AM tones, in the range of 1 to 128 kHz, can be configured (the detection range
is limited to 1 to 50 kHz). Note that when a tone is composed of a single frequency, the
second frequency field must be set to zero.
The format attribute can be one of the following:

Continuous: A steady non-interrupted sound (e.g., a dial tone). Only the 'First Signal
On time' should be specified. All other on and off periods must be set to zero. In this
case, the parameter specifies the detection period. For example, if it equals 300, the
tone is detected after 3 seconds (300 x 10 msec). The minimum detection time is 100
msec.

Cadence: A repeating sequence of on and off sounds. Up to four different sets of
on/off periods can be specified.

Burst: A single sound followed by silence. Only the 'First Signal On time' and 'First
