The Hub RF Chassis is a rack-mounted chassis capable of housing 8 industry standard cPCI
circuit card modules. The RF Chassis houses cooling fans and specific modules designed for
use in the Digivance CXD system. The backplane of the RF Chassis provides for distribution
of signals between modules including the reference clock, communications, control and data
signals. Modules used in the RF Chassis include up to two Full-band Hub Down-Converter
(FBHDC) modules, two Forward Simulcast Card (FSC) modules and two Hub Up-Converter
(HUC) modules.
Figure 2-5 shows the empty RF Chassis. The eight empty slots on the left are used for
Digivance CXD modules. The eight empty slots on the right used for housing the cPCI power
supplies which power the modules and the cPCI fan assembly.
