Version 5.0 367 December 2006
16 Configuration Files
This section describes the configuration dat files that are loaded (in addition to the ini file)
to the gateway. The configuration files include the following:
Call Progress Tones file (refer to Section 16.1 on page 367)
Prerecorded Tones file (refer to Section 16.2 on page 371)
CAS protocol configuration files (refer to Section 16.3 on page 372)
FXS/FXO Coefficient file (refer to Section 16.4 on page 372)
To load either of the configuration files to the Mediant 1000, use the Embedded Web
Server (refer to Section 5.8.2 on page 189) or alternatively specify the name of the relevant
configuration file in the gateway’s ini file and load it (the ini file) to the gateway (refer to
Section 5.8.2.2 on page 191).
16.1 Configuring the Call Progress Tones and Distinctive
Ringing File
The Call Progress Tones and Distinctive Ringing, configuration file used by the Mediant
1000 is a binary file (with the extension dat) that is comprised of two sections. The first
section contains the definitions of the Call Progress Tones (levels and frequencies) that are
detected / generated by the Mediant 1000. The second section contains the characteristics
of the distinctive ringing signals that are generated by the Mediant 1000.
Users can either use one of the supplied Mediant 1000 configuration (dat) files, or
construct their own file. To construct their own configuration file, users are recommended,
to modify the supplied usa_tone.ini file (in any standard text editor) to suit their specific
requirements, and to convert it (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 to a binary dat file, refer to Section E.1.1 on page 396.
Note: Only the dat file can be loaded to the Mediant 1000 gateway.
To load the Call Progress Tones (dat) file to the Mediant 1000, use the Embedded Web
Server (refer to Section 5.8.2 on page 189) or the ini file (refer to Section 5.8.2.2 on page
191).
16.1.1 Format of the Call Progress Tones Section in the ini File
Users 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 Hz 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.
