# AG board DSP requirements for NaturalFax

One or more DSP processors on AG boards are devoted entirely to fax operations when the board is loaded. Each DSP processor configured for fax supports eight ports of any fax operation. For each DSP processor devoted to fax, add an additional line to the board keyword file. For example, to assign DSP 0 to fax, use this sample line in the board keyword file:

DSP.C5x[0].Image = ag2fax.c54
DSP.C5x[0].Image = ag2faxa.c54

To determine if a board supports your application requirements, refer to the NMS OAM System User's Manual for IVR DSP requirements and the Fusion Developer's Manual for vocoder DSP requirements.
