Overview of RF Modules for Prism Remote Units
OVERVIEW OF RF MODULES FOR PRISM REMOTE UNITS
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.
RF MODULE DIGITAL/ANALOG RADIO TRANSCEIVERS
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.
