The CrossFire is divided into three logical functional units according to function:
•
Interface Processing Module (IPM): Interface switch and protocol analysis.
•
Downlink Channel Module (DCM): The AU terminal (upper layer of the DCM) converts RF signals into
digital signals and includes filtration and ADC conversion. The RU terminal (lower layer of the DCM)
converts digital signals into RF signals and includes DAC conversion and IQ modulation.
•
Uplink Channel Module (UCM): The RU terminal (upper level of the UCM) converts RF signals into
digital signals and includes filtration and ADC conversion. The AU terminal (lower level of the UCM)
converts digital signals into RF signals and includes DAC conversion and IQ modulation.
