# Modifying the board keyword file

On AG and CG boards, NaturalConference uses dedicated DSPs that cannot be used with other features such as IVR, fax, or NMS Fusion. Dedicating a DSP to NaturalConference can reduce the number of ports available for use with IVR. The number of IVR and NaturalConference ports simultaneously available depends on the board model installed and the configuration of the computer.

To declare DSPs as conferencing resources, modify the board keyword file to associate DSPs with a NaturalConference DSP file. Use one of the sample board keyword files provided with NaturalConference as a model. Choose a board keyword file that corresponds to the board installed on your system.

Follow this procedure to declare DSPs for use by NaturalConference:

Step | Action
1 | Open the board keyword file.
2 | For each board you want NaturalConference to use, add the following keyword and parameter: AG boards: DSP.C5x[n].Image = ag*.c54 CG boards: DSP.C5x[n].Files = cg* where n is the DSP number and * represents the NaturalConference DSP files. You can also specify a range of DSPs. For example: DSP.C5x[1..3].Image = ag2conf.c54 Refer to DSPs and conferencing resources for information about modifying the NMS OAM configuration file when implementing conferencing resource spanning.
3 | Save the modifications.
4 | Create a NaturalConference configuration file, as described in Setting up the NaturalConference configuration file.
5 | Run the board configuration utility to load or reload the board. If the configuration utility succeeds without error messages, NaturalConference works according to the resources declared in the NaturalConference configuration file.

Refer to the board-specific installation and developer's manual for a complete description of the keywords.

The board keyword files are located in the following directories:

Board type | Operating system | Directory
AG boards | Windows | \nms\ag\cfg
UNIX | /opt/nms/ag/cfg
CG boards | Windows | \nms\cg\cfg
UNIX | /opt/nms/cg/cfg

The following table lists sample keyword files for some of the AG and CG boards that support NaturalConference:

Board | Sample keyword file | Description

AG 2000/200 AG 2000C/200 AG 2000-BRI/200 | agpi2cnfa_200.cfg | Eight analog ports in A-law with one conferencing resource containing a single DSP.
AG 2000/400 AG 2000C/400 AG 2000-BRI/400 | agpi2cnf_400.cfg | Eight analog ports in mu-law with one conferencing resource containing three DSPs.
