• Ensure that HDC modules are connected to FSC modules as shown in the diagram.
HDC’s below an FSC have their outputs connected to FSC inputs 1, 3, 5, and 7. HDCs
above an FSC have their outputs connected to FSC inputs 2, 4, 6, and 8. HDCs using
composite mode will only require HDC Output IF 1 to be connected to FSC CH 1.
• An RF chassis in a Hub rack contains enough slots for 2 sets of tenant RF equipment,
where a set of tenant RF equipment consists of one FSC, one HUC and up to two
HDC’s. A set of tenant equipment in an RF chassis is installed in a particular manner,
from bottom to top, the order of modules is HUC, HDC, FSC, and HDC. The locations
of modules in the chassis must also follow a particular pattern, such that the first set of
tenant modules must occupy the four bottom-most slots in the chassis, the second set
must occupy the next four slots. Refer to Table 3-2. RF Chassis Configuration for
more details.
Table 3-2 illustrates the chassis configuration:

6.1 Understanding Tenant MIB Indexing
Throughout the Digivance CXD system, there are several MIB’s that are used to monitor and
control tenant activity. These tenant-based MIB’s contain tables with 96 separate
entries/columns, where each entry/column in a table belongs to a given tenant base station
sector. The index value used for each base station sector is constant across the entire system
such that once a tenant sector is configured and an index is established, the same index will be
associated with that tenant sector in all system-wide tenant-based MIB’s.
(*) The Digivance CXD system can support up to 96 unique base station sectors per Hub
Master CPU.
