Prism System Overview A block diagram of a point-to-point system is shown in Figure 4.
Prism System Overview The basic function of FlexWave Prism simulcast (point-to-multipoint) is to transport, via fiber optic cable, RF signals from a BTS to multiple antenna interfaces allowing communication to a mobile device (see Figure 5). Up to 8 simulcast Remote Units are supported by each Host Unit.
Fiber Optic Transport FIBER OPTIC TRANSPORT In a FlexWave Prism system, each BTS provides the RF channel inputs and outputs for a designated sector. Each Host may be interfaced with one or more Base Transceiver Station (BTS). On the forward path, the Host receives Analog RF signals from the BTS, digitizes the designated RF bands, and then transports them over single-mode fiber to up to 8 Remote Units.
Prism System Overview H OST U NIT O VERVIEW The rack-mountable Host is typically located with the RF source—a Base Transceiver Station (BTS). The Host is DC powered and supports up to eight BTS interfaces through DART (Digital/Analog Radio Transceiver) cards. (For further information on DART Modules, see “DART Modules” on page 24.
Host Unit Overview SeRF II Module The SeRF II Module: • manages communications and alarms • receives digitized signals from the DART and sends the digitized RF bands to the designated PRU • receives digitized RF signals from the PRU and sends the digitized RF signal to the DART for conversion from Digital RF to Analog RF for the BTS/BDA • supports eight Small Form-factor Pluggable (SFP) optical transceivers • provides two Ethernet interfaces.

Prism Remote Units PRISM REMOTE UNITS The Prism Remote Unit (PRU), shown in Figure 8, controls RF emissions, interfaces with the FlexWave Host and performs the optical to electrical conversions for transport to the antennas. The PRU is an IP-65 rated enclosure that houses the electronic assemblies such as the RF Module Group, SeRF assembly and AC/DC power supplies, and seals out dirt and moisture. The PRU uses fans located on the top of each unit to cool the chassis.

At system startup, the PRU Status LED is red to indicate that the PRU is powering up and that the SeRF processor does not yet control the PRU.
Prism System Overview PRU Components The PRU chassis is an outdoor-rated enclosure that comprises the following components: • Power Supplies • SeRF Module • Fans • Interface connections as described in “PRU Ports and Connectors (Bottom of PRU)” on page 17 • External Status LED (see “PRU Status LED (Bottom of PRU)” on page 18) • Remote (AC) power and RF Module (DC) power switches PRUs ship with specified RF Modules pre-installed.

Prism System Overview RF Module Capabilities and GUI Representation A PRU comprises from one to four RF Module slots. Each RF Module can comprise any of the following DART combinations: • one Classic DART or one Single SuperDART • two Classic DARTs • two Single SuperDARTs • one Dual SuperDART. A PRU can therefore comprise up to eight single-slot DARTS or up to four Dual SuperDARTs, dependent on the Remote chassis size and the number of RF Modules installed.
Prism Remote Units Table 1 and Figure 10 on page 23 describe how the EMS references the RF group assignments and corresponding components of each RF Module. Table 1.

DART Modules DART MODULES DART Modules: • amplify, down-convert, filter and digitize the incoming RF signal • convert incoming digital signal from the SeRF to analog, filter, amplify and up-convert the frequency from Intermediate Frequency (IF) to RF • provide a bi-directional interface between RF and the SeRF board (via FPGA, D/A converter, and A/D converter) • provide uplink gain • support Simplex RF interfacing to/from the BTS • perform adjustable delay processing.

Figure 11 provides generic representations of Classic DARTS or Single SuperDARTs and Dual SuperDARTs.

Prism System Overview Host DART Slots Figure 13 shows the possible slot assignments for Single and Dual SuperDARTs, and where slot-divider bars are located.
DART Modules Host DART Connectors and LEDs Only RF DART Modules can be installed in the Host Unit.
Prism System Overview Serialized RF (SeRF) Digital Protocol The SeRF (Serialized RF) digital protocol consists of digitized RF, Fast Ethernet, and Host to Remote communication and management. The protocol provides you with full access to the 100BASE-T (Ethernet) connection between the Host and each Remote, and the ability to provision the RF spectrum of the DARTs.
DART Modules Simulcast Groups Simulcast combining occurs when more than one Remote DART is linked to the same Host DART. The gains of the reverse signals are reduced before summation to prevent over-flow when the digital signals are added together. This simulcast gain reduction is accomplished as a function of the number of Remote DARTs linked to the Host DART (N) and the selected Reverse Gain Mode: • Mode 1 (Noise Floor Matching)—uses an algorithm that normalizes the noise floor of all Remote Units.
Prism System Overview Use of Multi Fibers The EMS provides the ability to install “multi fibers” between a Host and Remote. This means that, in addition to the minimum single fiber pair (RX and TX) in the Host to Remote connection, one or more additional fiber pairs are installed. This is done to increase the bandwidth or number of timeslots between the Host and Remote.
DART Modules E911 Support The DART type determines the maximum number of links, where there can be up up to 8 Classic DARTs or Single SuperDARTs that support 35MHz each, or up to 4 Dual SuperDARTs that support up to 75MHz each. E911 support may be achieved by using a configuration similar to the one shown in Figure 14. Remote simulcasting in this configuration requires analog splitting and combining to and from the individual Host DARTs.
