# CG board DSP requirements for NaturalFax

CG boards provide DSP processors that can simultaneously run multiple operations in a universal port model. Under this configuration, NaturalFax can support up to 120 ports of fax operation. These operations can include fax, a combination of other data processing functions (DPF), or both.

To run a fax operation, the NaturalFax DPF must be specified as one of the DSP files and as one of the resource definitions. For example, to load NaturalFax on DSPs 1 through 31, modify the board keyword as shown in the following example (CG 6000 boards only):

DSP.C5x[1..31].Files = nmsfax voice tone dtmf echo callp ptf mf
Resource[0].Definitions = (nmsfax | (dtmf.det_all & ptf.det_2f & voice.rec_24 &
(voice.play_24_100 | tone.gen)))
