HAPTER
This section describes the configuration (dat) files that are loaded (in addition to the ini file) to
the gateway. The configuration files are:
Call Progress Tones file (see
Prerecorded Tones file (see
Voice Prompts file (see
CAS protocol configuration files (see
To load any of the configuration files to the VCX V7122 use the Embedded Web Server (see
Auxiliary Files on page 86) 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 (see
Booting the Device on page 194).

Configuring the Call Progress Tones

The Call Progress Tones, configuration file used by the VCX V7122 is a binary file (with the
extension dat) which contains the definitions of the Call Progress Tones (levels and
frequencies) that are detected / generated by the VCX V7122.
Users can either use, one of the supplied VCX V7122 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" supplied with the software package. For the description of the procedure
on how to convert CPT ini file to a binary dat file, see
dat File on page 220.
Note that only the dat file can be loaded to the VCX V7122 gateway.
To load the Call Progress Tones (dat) file to the VCX V7122, use the Embedded Web Server
(see Auxiliary Files on page 86) or the ini file (see
page 136).

Format of the Call Progress Tones Section in the ini File

Using the CPT section of this configuration file, the User can create up to 16 different Call
Progress Tones using up to 15 different frequencies (in the range of 300 Hz to 1980 Hz).
Each of these Call Progress Tones is specified by its tone frequency (either single or dual
frequencies are supported) and its tone cadence. The tone cadence is specified by 2 sets of
on/off periods (you can discard the use of the first on/off cycle by setting the relevant
parameters to zero). When a tone is composed of a single frequency, the second frequency
field must be set to zero.
For a continuous tone (such as dial tone), only the "First Signal On time" should be specified.
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.
