edit the "source" CAS file in any text editor (as described 'CAS File Syntax' on page
) and convert it to the binary format using the
DConvert utility
(as described in

CAS File Syntax
This section describes syntax of the text-based "source" CAS file. Two files must be
created by the user:
Specific protocol/script text file (
xxx.txt
)
Numeric values file (
xxx.h
)
Both of these files must be converted to binary format via
DConvert utility
prior to
uploading them to the Media Gateway.
The
CASSetup.h
file, provided on the Media Gateway Software Installation CD,
includes all of the pre-defined tools needed to build a new "source" CAS protocol file
or modify an existing one.
