6.3 Hub Up Converter Card (HUC)
The Hub Up Converter (HUC) accepts two (2) Digital IF (DIF) signals from a SIF or RSC.
The two (2) DIF signals are converted from digital-to-analog and provided as two (2) separate
RF signals (primary and diversity) to the BIM and BTS.
The HUC, shown in Figure 2-18, can be inserted into slots 1 and 5 in the Hub RF cPCI chassis.
The outputs of the HUC are cabled to the reverse path inputs of the BIM module. Refer to
Table 2-17 for BIM to HUC interconnect. There are two RF cables per HUC for primary and
diversity. Cables are routed from BIM down or up to SMA connector of the adjacent HUC.
The references for the HUC are shown in Table 2-12.
