6.4 Reverse Simulcast Card (RSC)
The Reverse Simulcast Card (RSC) is shown in Figure 2-19. The RSC sums the Digital IF (DIF)
from up to four (4) RANs into a single DIF signal that is sent to the HUC via DIF cables and the
chassis rear panel for conversion to RF. The RSC is utilized in the Digital Chassis and is specified
as one per tenant per sector per 4 RANs, plus an additional one RSC for RANs 5-7, and an
additional one RSC for RAN 8. The references for the RSC are shown in Table 2-13.
