# 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:

Resource[0].Definitions = (nmsfax | dtmf.det_all & callp.gnc & \
(tone.gen | (rvoice.rec_mulaw & rvoice.play_mulaw) | (voice.rec_32 & voice.play_32_100)))
Resource[0].DSPs = 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31
