System DescriptionThe addresses of the EMRPM are set using a DIP switch on the unit. Noaddress plug is required. The address is dependent upon the configurationof the RBS site and number of cabinets used.The site installation documentation shows how the switches are to be setfor a specific site.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 four TRXs (carriers) for each antenna system, whichprovides 11 digital voice paths per sector.4/1551-EN/LZB 119 3312 Uae Rev PA4 1998-10-05 3-15

System Description•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 RBS 884 Micro (1900 MHz)Installation and Hardware Replacement Manual for further information onthe fan replacement procedure.4/1551-EN/LZB 119 3312 Uae Rev PA4 1998-10-05 3-17

Cascading is used to expand a site andto create different Radio Cabinet Groups (RCGs) at the same site.Drop and insert considerations become important when planning thecascading of an RBS site.Each 1900 MHz micro base will become a separate Extension ModuleGroup (EMG) and have its own control channel (DS0 - 64 kbit/s channel)on the PCM (T1/E1) transmission cable interconnections.Additional Control Signaling Link (CLC) extraction time slots will berequired for each additional REMUX introduced to support cascading.This allocation is determined by the operator or network provider. EachREMUX will require all switch settings to be checked and reset asnecessary (see the Processes and Procedures part of this manual).To maintain transmission quality, it is recommended that no more thanfour RBS 884 Micro (1900 MHz) base stations be cascaded.4/1551-EN/LZB 119 3312 Uae Rev PA4 1998-10-05 3-25

Report to the MSC to re-activate the system.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.1/1551-EN/LZB 119 3312 Uae Rev PA4 1998-10-05 4-57
InstallationIf 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 flow circulatingthe heated air trough the cabinet. When the Subrack Thermal Mass reaches10 C, the ECU applies power the Subrack Power Bus and the CSU.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.15 Completing the InstallationThis section describes the general housekeeping duties required tocomplete the installation.15.1 Prerequisites and Tools15.1.1 PrerequisitesThe Installation Completion Procedure can be completed only after theequipment has been successfully powered up in accordance with Section13 on page 4-54.15.1.2 ToolsA tie-wrap tool is required to complete the Installation CompletionProcedure.15.2 Installation Completion ProcedureGeneral housekeeping1.

Hardware Replacement1 IntroductionThis part of the manual lists procedures for basic troubleshooting andhardware replacement of faulty items of equipment, such as cabinet unitsor cables.The use of the procedures by a site maintenance technician may depend oninstructions from MSC personnel able to determine the status of the RBSsite equipment from the MSC.The site maintenance technician may be asked to replace a particular unitusing the procedure in Section 6 on page 5-14, or to follow thetroubleshooting procedure in Section 4 on page 5-6 for determining afaulty unit. The troubleshooting procedure is also used if failures occurduring the power-up procedure.2 Safety Considerations2.1 Grounding of the RBS CabinetsThis product is Safety Class 1 equipment.The RBS cabinets must be connected to the AC power through a groundedpower cable, with the ground wire firmly connected to an electrical ground(safety ground) at the power outlet.2/1551-EN/LZB 119 3312 Uae Rev PA4 1998-10-05 5-3
Hardware ReplacementDANGER!Any interruption of the protective (grounding) conductor, or disconnectionof the protective ground terminal will cause a potential shock hazard thatcould result in personal injury.2.2 Voltage HazardsDANGER!Voltage over 100V is used in the AC equipment at the site. Observe safetyprecautions. Contact with power can cause death. Do not be misled by theterm “low voltage”. Under adverse conditions, potentials as low as 50Vcan result in death. Do not work alone while working with AC power.DANGER!Do not touch high voltage connections when installing or operatingequipment. If necessary, disconnect the AC power cable from the powerunit. Do not connect the AC power cable to the power unit when the unitis removed from the RBS cabinet.The power cable serves as the only power disconnection device for thecabinet.Keep one hand away from the equipment, if the nature of the maintenancepermits, to reduce the possibility of current flowing through vital bodyorgans.2.3 Radio Frequency RadiationDANGER!Radio frequency radiation from an antenna may be a danger to health,causing severe burns to skin and clothing.All transmitters must be disabled prior to working with or near antenna.2.4 Beryllium OxideSome equipment contains beryllium oxide in ceramic form.5-4 2/1551-EN/LZB 119 3312 Uae Rev PA4 1998-10-05
Hardware ReplacementWarning!Beryllium oxide is poisonous and constitutes a health hazard if present infinely dispersed form, such as dust or smoke, which can be inhaled. Readlocal hazardous chemical regulations before working with beryllium oxide.Units with components containing beryllium oxide are marked with awarning label. For detailed information on properties, health andenvironmental hazards, refer to the regulations issued by the localauthorities.The following rules must be obeyed by all persons handling berylliumoxide:•Ceramics containing beryllium oxide must not be scraped, filed,ground, treated with acid or machined in any other way.•Compressed air must not be used to clean units containing berylliumoxide.•You must always wear protective gloves when handling berylliumoxide.•Use wet rags to collect dust and particles from damaged berylliumoxide components. After use, place the rags in plastic bags and sealthe bags completely.Scrapped beryllium oxide must be treated as environmentally hazardouswaste. Local authorities enforce regulations, regarding the treatment anddisposal of environmentally hazardous waste. Investigate the localregulations which are applicable to you and comply with them.2.5 Heavy LoadsWarning!A heavy load lifted incorrectly can cause injury to persons and damage tothe equipment can result.A heavy load is considered to be 10 kg (approximately 22 lbs).Note: A fully equipped RBS 884 Micro (1900 MHz) cabinet exceeds105 kg (230 lbs). Therefore Ericsson recommends that twopersons are present during the installation.2/1551-EN/LZB 119 3312 Uae Rev PA4 1998-10-05 5-5
Hardware Replacement3 Product Handling and InspectionComponents may be damaged because of ESD. Read the ElectrostaticDischarge section for information and directions.A hardware replacement unit must always be kept in its original box untilit is installed on a site.The unit must not be exposed to wide variations in temperature, to directsunshine, or to high levels of humidity, such as may occur if the unit isleft in a car.When handling circuits boards, do not touch any components or connectorpins.If the packing material is damaged, inspect the unit immediately. If theunit appears to be damaged, follow your local procedures or return it toyour local service center for repair or hardware replacement.A faulty unit must always be accompanied by a completed Repair TravelerNote, with written information concerning the circumstances of thesuspected fault. A Repair Traveler Note is a tie-on tag, which can beattached to the unit.4 General TroubleshootingOperational status of the RBS equipment is indicated by LEDs mounted onthe front of the units plugged into the cabinets.In general, green LEDs are used for power status, red LEDs are used forerror status, and yellow LEDs are used to indicate other types ofoperational status.The procedure in this section is used to determine faulty units by visualinspection of the LEDs and other means. If the procedure does not resultin the detection of a faulty unit, the MSC must be informed in order todetermine if a problem at the site is still indicated at the MSC.4.1 Prerequisites and Tools4.1.1 PrerequisitesThe troubleshooting procedure in this section is intended to be followed ifan RBS unit fault is detected during the power-up procedure, or at therequest of the MSC as a result of an RBS site equipment error indicationat the MSC.5-6 2/1551-EN/LZB 119 3312 Uae Rev PA4 1998-10-05
