Figure 1. Prism Remote Units (PRUs)
Depending 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:
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.
