6 Auxiliary Configuration Files
This section describes the auxiliary files (with the
dat
file extension), which are loaded, in
addition to the
ini
file, to the device. You can load the auxiliary files to the device using one
of the following methods:
„ Web interface (refer to ''Loading Auxiliary Files'' on page 231 )
„
ini
file: specify the name of the relevant auxiliary file in the device's
ini
file and then
load the
ini
file to the device (refer to ''Loading Auxiliary Files'' on page 231 ).
6.1 Configuring the Call Progress Tones File
The Call Progress Tones (CPT) auxiliary file used by the device is a binary file (with file
extension
dat
). This file contains the definitions of the Call Progress Tones (levels and
frequencies) that are detected / generated by the device.
You can either use one of the supplied device auxiliary (
dat
) files or create your own file. To
create your own auxiliary file, it's recommended to modify the supplied
usa_tone.ini
file (in
any standard text editor) to suit your specific requirements, and to convert the modified
ini
file into binary format using the TrunkPack Downloadable Conversion Utility. For the
description of the procedure on how to convert CPT
ini
file into a binary
dat
file, refer to the
Product Reference Manual
.
To load the Call Progress Tones
(dat
) file to the device, use the Web interface or
ini
file
(refer to ''Loading Auxiliary Files'' on page 231 ).
Note:
Only the
dat
file 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). In total, 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:
(e.g., dial tone) a steady non-interrupted sound. 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
Signal Off time' should be specified. All other on and off periods must be set to zero.
The burst tone is detected after the off time is completed.
You can specify several tones of the same type. These additional tones are used only for
tone detection. Generation of a specific tone conforms to the first definition of the specific
tone. For example, you can define an additional dial tone by appending the second dial
tone's definition lines to the first tone definition in the
ini
file. The device reports dial tone
detection if either of the two tones is detected.
