Dependent on the Prism Remote Unit model, a PRU enclosure can have from one to four RF Module bays and can
support up to four RF Modules, as indicated by the model name. That is, the Single-Bay PRU has one RF Module
bay and can only support one RF Module, and the Quad-Bay PRU has four RF Module bays and can support up to
four RF Modules.
The function of the Remote Unit RF Modules on the Forward Path is to:
•
convert the digitized RF transported from the Host to Analog RF
•
amplify the Analog RF signal
•
provide signal filtering.
The function of the Remote Unit RF Modules on the Reverse Path is to:
•
convert the Analog RF from the handset to Digital RF for transport to the Host
•
amplify the Digital RF signal
•
provide signal filtering.
NOTE:
The RF Modules are field replaceable, but cannot be serviced in the field.

Each RF Module can support any of the following Digital/Analog Radio Transceiver (DART) combinations:
•
one Classic DART or one Single SuperDART
•
two Classic DARTs (i.e., the 6.5W 800/900 ESMR Module, Non-Diversity, Classic)
•
two Classic DARTs—Diversity
•
two Single SuperDARTs—Diversity
•
one Dual SuperDART
•
one or two sets of Tx and Rx Boards (HDM).
Each RF Module will have up to two 6-timeslot DARTs or one 12-timeslot DART per RF Module.
The DART type determines the maximum number of links, where there can be up to eight Classic DARTs or Single
SuperDARTs that support 35 MHz each, or up to 4 Dual SuperDARTs that support up to 75MHz each.
