1.7.3System Interface (STF2) Module

The System Interface (STF2) Module is a cPCI electronic module that provides the CPU and other electronic modules with the ability to communicate with one another using the four I2C buses on the cPCI backplane. One STF2 is used per RAN. The STF2 also has the GPS antenna input port located in the center of the module faceplate. STF2 modules are specified according to the number of qualifying communications devices being utilized. Table 6 describes the module faceplate components. Figure 10 shows the location of the faceplate components.
