• Ensure that FBHDC modules are connected to FSC modules. (See Hub Installation
and Maintenance Manual for details)
• 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
FBHDC’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, FBHDC, FSC, and
FBHDC. 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.

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.
Note: The Digivance CXD system can support up to 96 unique base station sectors per
Hubmaster CPU.
