NaturalFax DSP Requirements

The NaturalFax installation provides you with AG configuration files for several common fax and voice applications on supported AG boards. If your application requirements are different, you may need to adjust your configuration, or run fewer ports of voice and fax functions. The table below provides the MIPS requirements for the fax DSP overlays. Use this information and the information provided in Appendix B of the AG Access Installation Manual to determine the MIPS requirements for your application.
It is important to test your application with the expected AG hardware configuration, mix of functions, and number of active ports. This load testing will confirm that sufficient DSP resources exist to handle your application in the field.
