System Descri tionThe addresses of the EMRPM are set using a Double Inline Pack (DIP)switch on the unit. No address plug is required. The address is dependentupon the configuration of the RBS site and number of cabinets used.A computer can be connected to the TW/DEB port at the front of theEMRPM unit. The interface has the same function as the V24–B3 unit.2.7 Transceiver (TRX)The transceiver (TRX) transmits and receives radio signals to and frommobile stations.A TRX unit can be remotely configured to support any of the followingchannel functions:•Digital Voice Channel (DVC) – transmits and receives•Digital Control Channel DCCH) – transmits and receives•Digital Verification (DVER) Channel – receives onlyThe selection of transceiver channel function is under software control atthe Mobile Switching Center (MSC). The first time slot may be used forDCCH and the remaining two time slots for DVCs, or all three time slotsmay be used for DVCs.The TRX provides 33.3 dBm (2.1 W) per carrier at the ANP for the two-antenna configuration and 36.8 dBm (4.8 W) per carrier at the ANP for thefour-antenna configuration. The dynamic range is 20 dB with 0.2–dBresolution.The TRX includes all functionality needed for one RF channel, such as:•Channel coding and decoding•Modulation and demodulation•Power amplification•Power regulation•Synchronization•Diversity combining•Measurements on received radio signal•Verification processing (when configured as DVER)The maximum output power for each TRX is 13.5 W. Note that digitalspeech coding takes place in the voice coder units in the MSC and not inthe TRXs. There are 4 TRXs (carriers) for each antenna system thatprovide 11 digital voice paths per sector.Table 3-5 on page 3-16 shows the allocation slots for TRX units incabinets that are not fully equipped.

System Descri tion•Calibrate TRX transmitter and receivers•Antenna supervisionThe ANP, RFTL, and integrated filters are combined in a single ANP/RFTL assembly and reside in the subrack. The backplane of the subrackcontains a five–way power splitter for each receiver diversity branch. TheANP/RFTL assembly provides a single signal for each diversity branchwith all splitting performed in the backplane. This design allows all fiveTRXs to receive the same signal at the same level.2.9 Environmental Control UnitThe Environmental Control Unit (ECU) runs a control loop that monitorsthe internal cabinet temperature at several different locations. Using thesereadings, the ECU maintains the cabinet at an acceptable temperature bycontrolling the speed of the fans and the power to the heater. When theECU is unable to maintain the cabinet at an acceptable temperature, theECU provides alarms to the switch through the EMRPM and ALM boardsand can ultimately remove power from the subrack and shut down the basestation.2.10 FansThe RBS 884 Micro (1900 MHz) uses four variable speed-controlled fansto regulate the temperature of the circuit cards and modules in the cabinet.The fan control is driven by an open thermal control loop that referencesthe outside ambient air temperature. The temperature sensor for the fancontrol is located in an area that is not affected by solar exposure nor bypower dissipation from the cabinet. The amount of air flow through thecabinet is limited to that required to maintain the components within theirtemperature specifications.The fans are controlled by the ECU. The ECU is capable of varying thespeed of the fans and can turn off one or more of the fans during lowtemperature extremes and during cold temperature start-up. To insure fail-safe operation, the fans operate at full speed when the thermal sensorsignal is lost.The fans are modular units and can be easily accessed from the top doorof the RBS 884 Micro (1900 MHz) cabinet. Fan replacement is done withthe fan breaker in the ON position. Base station personnel cycle the fanbreaker off and on to reset the fan alarm after they complete the fanreplacement procedure. Refer to the “Hardware Replacement” part of theInstallation and Hardware Replacement Manual for further information onthe fan replacement procedure.4/1551-EN/LZB 119 3312 Uae Rev A 1998-11-17 3-17

See Figure 4-19 on page 4-38 for a close-up view of the T1(E1) Primary SurgeSuppressor and Table 4-5 on page 4-33 for information on theinput connections. Note that the connector block is grounded to theI/O plate at the factory.Note: The hex-nut activators on the T1(E1) Primary SurgeSuppressor block are colored white for tip wires andorange for ring. The large ports under the activatorclock accommodate 18.5 to 20 AWG wire termination.The small ports accommodate 22 to 24 AWG wiretermination. Wire stripping or staggering is not neededwhen using the T1(E1) Primary Surge Suppressorblock. The Primary Surge Suppressor providesstraight-through access for wire terminations.8. Trim the ends of the wire. Split the drop leads approximately twoinches. Using a standard 216–type wrench, carefully back off theactivator screw until you feel a stop. The wrench will lift upapproximately 1/4–inch into the open position.9. Insert the wire into the large or small port on the side of theactivator. Tighten the hex nut on the top of the activator until thetensions stops. Do not overtighten.10. If testing or if a talk pair is needed, insert test leads into the hexnut on the appropriate activator.11. To reinstall wires, trim the wire ends and split the drop wire leadsapproximately two inches and terminate according to the aboveprocedure.12. After wiring, keep all activators in the down position for goodhousekeeping.13. After all cables are installed, turn on the AC power.14.

Repeat Step 1 on page 4-54 to Step 9 on page 4-56 for each cabinet.11. Inform the MSC operator that the unit has been replaced and is readyto be tested.14 Cold Start-upDuring an AC power-on event, the ECU checks the temperature of theequipment before allowing DC power to be distributed to the rest of theequipment. The ECU prohibits the equipment from operating when itstemperature is outside the safe function limits (-5 C to +50 C). The cold-start mode is used when AC is first applied and the subrack thermal masstemperature is below the subrack inlet temperature limit of 10 C.If a cold start-up condition exists, heaters are activated to warm the cabinettemperature. The heater is controlled by a variable voltage from the ECU(5Vdc to 12Vdc) to provide 80 to 1600 watts of variable heat.During the warm-up period, the fans operate at 20% of full flowcirculating the heated air trough the cabinet. When the subrack thermalmass reaches 10 C, the ECU applies power to the Subrack Power Bus.The warm-up time from AC power-on until the equipment reachesoperational temperature varies with the initial equipment temperature. Atan initial equipment temperature of -35 C, the warm-up can takeapproximately 55 minutes.The ECU does not generate any alarms to the MSC during a cold start-up.The ECU Cold Start error code (C0) does appear on the ECU LED display.15 Completing the InstallationThis section describes the general housekeeping duties required tocomplete the installation.4-56 1/1551-EN/LZB 119 3312 Uae Rev A 1998-11-17
