5.2 System Interface (STF2)
The System Interface (STF2) module, shown in Figure 2-13, is installed into the Digital
Chassis and RAN Chassis and provides the ability to communicate between the CPU and other
modules (e.g., FBHDC, FSC, HUC, RUC and RDC), using four I2C busses. The STF2 also
communicates with the GPS module found in the Hubmaster Hub Reference Module. The
STF2 used at the RAN differs from the module at the Hub in that it has the GPS antenna input
located in the center of the module and additional GPS circuitry to control that device. STF2
modules are specified according to the number of qualifying communications devices being
utilized. The references for the STF2 are shown in Table 2-8.
