This subsystem provides an interface between AFMS and the monitoring equipment. Using its functions, the Administration's personnel will have the ability to program the monitoring equipment. The resulting processed data from the monitoring equipment can then be transferred to AFMS to support the frequency assignment process and to identify illegal users of the spectrum. This subsystem provides occupancy and loading information on conventional and trunked radio systems. It is used to determine the use of discrete frequency assignments and spectrum occupancy statistics.

The Spectrum Surveillance Analysis subsystem enables Spectrum Management Engineers to produce frequency lists for monitoring and assists with the analysis of the resulting monitoring data. Monitoring data is used to determine the extent to which the frequency spectrum is occupied, to ensure that licensees are operating in accordance with the terms and conditions of their license, and to identify potentially non-licensed radio operations.
