Optimization OverviewApr 2001 1-1SCt4812ET BTS Optimization/ATP — CDMA LMFDRAFTScope of This DocumentThis document provides information pertaining to the optimization andaudit tests of Motorola SC 4812ET Base Transceiver Subsystem (BTS)equipment frames equipped with trunked high–power Linear PowerAmplifiers (LPAs) and their associated internal and external interfaces.This document assumes the following prerequisites: The BTS framesand cabling have been installed per the BTS Hardware Installation Manual– 68P64114A22, which covers the physical “bolt down” of all SC seriesequipment frames, and the specific cabling configurations.Document CompositionThis document covers the following major areas:SIntroduction, consisting of preliminary background information (suchas component and subassembly locations and frame layouts) to beconsidered by the Cell Site Field Engineer (CFE) before optimizationor tests are performed.SPreliminary Operations, consisting of cabinet power up and powerdown procedures.SOptimization/calibration, covering topics of Local MaintenanceFacility (LMF) connection to the BTS equipment, Global PositioningSystem (GPS) Verification, test equipment setup, downloading allBTS processor boards, RF path verification, Bay Level Offset (BLO)calibration and calibration audit, and Radio Frequency DiagnosticSystem (RFDS) calibration.SAcceptance Test Procedures (ATPs), consisting of ATP tests executedby the LMF and used to verify all major transmit (TX) andreceive (RX) performance characteristics on all BTS equipment.SPreparing to leave the site, presents instructions on how to properlyexit customer site, ensure that all equipment is operating properly, andall work is complete according to Motorola guidelines.SBasic troubleshooting, consisting of procedures for installation,calibration, transmit and receive tests, backplane problems, GPSfailures, and module connectors.SAppendices contain pertinent Pseudorandom Noise (PN) Offset,frequency programming, output power data tables, data sheets that arefilled out manually by the CFE at the site, and information on testequipment preparation.1
Optimization Overview – continuedDRAFTSCt4812ET BTS Optimization/ATP — CDMA LMF Apr 20011-2CDMA LMF Product DescriptionThe Code Division Multiple Access (CDMA) LMF is a graphical userinterface (GUI) based LMF. This product is specifically designed toprovide cellular communications field personnel the vehicle to supportthe following CDMA BTS operations:SInstallationSMaintenanceSCalibrationSOptimizationThe LMF also provides Command Line Interface (CLI) capability.Activate the CLI by clicking on a shortcut icon on the desktop. The CLIcannot be launched from the GUI, only from the desktop icon.Online HelpTask oriented online help is available in the LMF by clicking on Helpfrom the menu bar.Why Optimize?Proper optimization and calibration assures:SAccurate downlink RF power levels are transmitted from the site.SAccurate uplink signal strength determinations are made by the site.What Is Optimization?Optimization compensates for the site-specific cabling and normalequipment variations. Cables that interconnect the BTS and Duplexerassemblies (if used), for example, are cut and installed at the time of theBTS frame installation at the site. Site optimization guarantees that thecombined losses of the new cables and the gain/loss characteristics andbuilt-in tolerances of each BTS frame do not accumulate, causingimproper site operation.Optimization identifies the accumulated loss (or gain) for all receive andtransmit paths at the BTS site, and stores that value in a database.SThe RX path starts at the ancillary equipment frame RFDS RXdirectional coupler antenna feedline port, through the RX input porton the rear of the frame, through the DDRCs, Multicoupler PreselectorCard (MPC), and additional splitter circuitry, ending at a CDMAChannel Processor (C–CCP) backplane Broad Band Transceiver(BBX) slot in the C–CCP shelf.SA transmit path starts at the BBX, through the C–CCP backplane slot,travels through the LPA/Combiner TX Filter and ends at the rear ofthe input/output (I/O) Panel. If the RFDS option is added, then theTX path continues and ends at the top of the RFDS TX directionalcoupler antenna feedline port installed in the ancillary equipmentframe. . . . continued on next page1
Optimization Overview – continuedApr 2001 1-3SCt4812ET BTS Optimization/ATP — CDMA LMFDRAFTThese values are factored in by the BTS equipment internally, leavingonly site specific antenna feed line loss and antenna gain characteristicsto be factored in by the CFE when determining site Effective RadiatedPower (ERP) output power requirements.Each C–CCP shelf BBX board is optimized to a specific RX and TXantenna port. (One BBX board acts in a redundant capacity for BBXs1–12, and is optimized to all antenna ports). A single value is generatedfor each path, thereby eliminating the accumulation of error that wouldoccur from individually measuring and summing the gain and loss ofeach element in the path.When to OptimizeNew InstallationsAfter the initial site installation, the BTS must be prepared for operation.This preparation includes verifying hardware installation, initial powerup, and GPS verification. Basic alarm tests are also addressed.A calibration audit of all RF transmit paths is performed to verify factorycalibration.A series of ATP CDMA verification tests are covered using the actualequipment set up. An ATP is also required before the site can be placedin service.Site ExpansionOptimization is also required after expansion of a site.Periodic OptimizationPeriodic optimization of a site may also be required, depending on therequirements of the overall system.Repaired SitesVerify repair(s) made to the BTS by consulting an Optimization/ATPTest Matrix table. This table outlines the specific tests that must beperformed anytime a BTS subassembly or RF cable associated with it isreplaced.Refer to Appendix B for detailed basic guideline tables anddetailed Optimization/ATP Test Matrix.IMPORTANT*1

Optimization Overview – continuedDRAFTSCt4812ET BTS Optimization/ATP — CDMA LMF Apr 20011-6Required Test EquipmentTo ensure consistent, reliable, and repeatable optimization test results,test equipment meeting the following technical criteria should be used tooptimize the BTS equipment. You can, of course, substitute testequipment with other test equipment models supported by the LMFmeeting the same technical specifications.During manual testing, you can substitute test equipmentwith other test equipment models not supported by theLMF, but those models must meet the same technicalspecifications.NOTEThe customer has the responsibility of accounting for any measurementvariances and/or additional losses/inaccuracies that can be introducedas a result of these substitutions. Before beginning optimization ortroubleshooting, make sure that the test equipment needed is on handand operating properly.Test Equipment CalibrationOptimum system performance and capacity depend on regular equipmentservice, calibration, and characterization prior to BTS optimization.Follow the original equipment manufacturer (OEM) recommendedmaintenance and calibration schedules closely.Test Cable CalibrationEquipment test cables are very important in optimization. Motorolarecommends that the cable calibration be run at every BTS with the testcables attached. This method compensates for test cable insertion losswithin the test equipment itself. No other allowance for test cableinsertion loss needs to be made during the performance of tests.Another method is to account for the loss by entering it into the LMFduring the optimization procedure. This method requires accurate testcable characterization in a shop. The cable should be tagged with thecharacterization information prior to field optimization.Equipment Warm–upAfter arriving at the a site, the test equipment should be plugged in andturned on to allow warm up and stabilization to occur for as long aspossible. The following pieces of test equipment must be warmed–up fora minimum of 60 minutes prior to using for BTS optimization or RFDScalibration procedures.SCommunications test setSRubidium time baseSPower meter1

BTS Equipment IdentificationApr 2001 1-13SCt4812ET BTS Optimization/ATP — CDMA LMFDRAFTEquipment OverviewThe SC 4812ET BTS consists of an RF Cabinet that is an outdoor,weatherized version of the SC 4812T. The RF cabinet is powered by27 Vdc and each cabinet has the capability to support up to 4 carriers (at3 sector) or 2 carriers (at 6 sector).The RF Cabinet houses the fan modules, C–CCP, LPA modules, LPAtrunking backplane, Bandpass 2:1 & 4:1 Combiners, Duplexer/ReceiveFilter/Directional Couplers (DRDC) and a DC Power distributionassembly. The Power Cabinet (PC) provides +27 Vdc distribution andbattery backup for the SC 4812ET. The Power Cabinet houses batteries,battery heaters, rectifiers, an AC Load Center (ACLC), a powerdistribution assembly, and two duplexed GFCI convenience outlets.Logical BTSA logical BTS can consist of up to four SC 4812ET frames. When theLMF is connected to frame 1 of a logical BTS, you can access alldevices in all of the frames that make up the logical BTS. A logical BTSCDF file that includes equippage information for all of the logical BTSframes and their devices is required. A Centralized Base StationController (CBSC) file that includes channel data for all of the logicalBTS fames is also required.The first frame of a logical BTS has a –1 suffix (e.g., BTS–812–1) andother frames of the logical BTS are numbered with suffixes, –101, –201,and –301 (e. g. BTS–812–201). When you log into a BTS a FRAMEtab is displayed for each frame. If there is only one frame for the BTS,there will only be one tab (e.g., FRAME–282–1) for BTS–282. If alogical BTS has more than one frame, there will be a separate FRAMEtab for each frame (e.g. FRAME–438–1, FRAME–438–101, andFRAME–438–202 for a BTS–438 that has all three frames). If anRFDS is included in the CDF file, an RFDS tab (e.g., RFDS–438–1)will be displayed.Actions (e.g., ATP tests) can be initiated for selected devices in one ormore frames of a logical BTS. Refer to the Select devices help screenfor information on how to select devices.C–CCP Shelf Card/Module Device ID NumbersAll cards/modules/boards in the frames at a single site, assigned to asingle BTS number, are also identified with unique Device ID numbersdependent upon the Frame ID number in which they are located. Refer toTable 1-3 and Table 1-4 for specific C–CCP Shelf Device ID numbers.1

Once power is applied a series of AC Voltagemeasurements is required.Table 2-3: AC Voltage MeasurementsStep Action1Measure the AC voltages connected to the AC load center (access the terminals from the rear of thecabinet after removing the AC load center rear panel). See Figure 2-2.2Measure the AC voltage from terminal L1 to neutral. This voltage should be in the range of nominally115 to 120 V AC.3Measure the AC voltage from terminal L1 to ground. This voltage should be in the range of nominally115 to 120 V AC.4Measure the AC voltage from terminal L2 to neutral. This voltage should be in the range of nominally115 to 120 V AC.5Measure the AC voltage from terminal L2 to ground. This voltage should be in the range of nominally115 to 120 V AC.6Measure L1 – L2 – should be from 208 to 240 V AC. If the AC voltages are in excess of 120 V (or exceed200 V) when measuring between terminals L1 or L2 toneutral or ground, STOP and Do Not proceed until thecause of the higher voltages are determined. The powercabinet WILL be damaged if the Main breaker is turnedon with excessive voltage on the inputs.CAUTION2

Table 2-4 provides the procedure for applying ACpower.Table 2-4: Applying AC PowerStep Action1When the input voltages are verified as correct, turn the Main AC breaker (located on the front of theAC Load Center) ON. Observe that all eight (8) green LEDs on the front of the AC Load Center areilluminated (see Figure 2-7).2Turn Rectifier 1 and Rectifier 2 AC branch breakers (on the AC Load Center) ON. All the installedrectifier modules (see Figure 2-7) will start up and should each have two green LEDs (DC and Power)illuminated.3Turn the Meter Alarm Panel module, ON (see Figure 2-3), while observing the K2 contact in thePDA assembly (see Figure 2-9). The contact should close. The Meter Alarm Panel voltage metershould read approximately 27.4 + 0.2 Vdc.4Turn the Temperature Compensation Panel (TCP) ON, (see Figure 2-4). Verify that the Meter AlarmControl Panel does not have any alarm LEDs illuminated.5Check the rectifier current bargraph displays (green LED display on the rectifier module). Noneshould be illuminated at this point.If batteries are fitted, turn on the two battery heater ACbreakers on the AC Load Center.NOTE2

The voltage should read 27.4 + 0.2 Vdc. Adjust Master Voltage on MeterAlarm Panel if necessary. Release the TCP 25° C set button.2Depending on the ambient temperature, the voltage reading may now change by up to + 1.5 Vcompared to the reading just measured. If it is cooler than 25_C, the voltage will be higher, and if it iswarmer than 25_C, the voltage will be lower.3Ensure the RF cabinet 400 Amp main DC breaker is OFF.4Close the three (3) Main DC breakers on the Power Cabinet ONLY. Close by holding in the resetbutton on the front of the PDA, and engaging one breaker at a time.5Measure the voltage between the + and – terminals at the rear of the Power Cabinet and the RFCabinet, observing that the polarity is correct. The voltage should be the same as the measurement instep 2.6Place the probes across the black and red battery buss bars in each battery compartment. Place theprobe at the bottom of the buss bars where the cables are connected. The DC voltage should measurethe same as the previous step. 2
Initial Power Up – continuedApr 2001 2-7SCt4812ET BTS Optimization/ATP — CDMA LMFDRAFTDC Power Pre-test (BTS Frame) Before applying any power to the BTS cabinet, verify there are no shortsin the RF or power DC distribution system (see Figure 2-5).Table 2-6: DC Power Pre–test (BTS Frame)Step Action1Physically verify that all AC rectifiers supplying power to the RF cabinets are OFF or disabled (seeFigure 2-5). There should be no 27 Vdc on DC feed terminals.2On each RF cabinet:SUnseat all circuit boards/ modules in the distribution shelf, transceiver shelf, and Single CarrierLinear Power Amplifier (SCLPA) shelves, but leave them in their associated slots.SUnseat all circuit boards (except CCD and CIO cards) in the C–CCP shelf and LPA shelves, butleave them in their associated slots.SSet C–CCP shelf breakers to the OFF position by pulling out power distribution breakers (labeledC–CCP 1, 2, 3 – located on the power distribution panel).SSet LPA breakers to the OFF position by pulling out power distribution breakers (8 breakers,labeled 1A–1B through 4C–4D – located on the power distribution panel).3Verify that the resistance from the power (+) feed terminals with respect to the ground terminal on thecabinet measures > 500 Ω (see Figure 2-5).SIf reading is < 500 Ω, a short may exist somewhere in the DC distribution path supplied by thebreaker. Isolate the problem before proceeding. A reading > 3 MΩ could indicate an open (ormissing) bleeder resistor (installed across the filter capacitors behind the breaker panel).4Set the 400 Amp Main Breaker and the C–CCP breakers (C–CCP 1, 2, 3) to the ON position bypushing them IN one at a time. Repeat step 3 after turning on each breaker.* IMPORTANTIf, after inserting any board/module, the ohmmeter stays at 0 Ω, a short probably exists in thatboard/module. Replace the suspect board/module and repeat the test. If test still fails, isolate theproblem before proceeding.5Insert and lock the DC/DC converter modules into their associated slots one at a time. Repeat step3after inserting each module.SA typical response is that the ohmmeter will steadily climb in resistance as capacitors charge, finallyindicating approximately 500 Ω.!

The DC current measured should be approximately the same. Ifthere is a wide variation between one cable and the others (>20 A), check the tightness of theconnections (torque settings) at each end of the cable.

Initial Power Up – continuedDRAFTSCt4812ET BTS Optimization/ATP — CDMA LMF Apr 20012-10Battery Charge Test(Connected Batteries)Table 2-8 lists the step–by–step instructions for testing the batteries.Table 2-8: Battery Charge Test (Connected Batteries)Step Action1Close the battery compartment breakers for connected batteries ONLY. This process should becompleted quickly to avoid individual battery strings with excess charge currentNOTEIf the batteries are sufficiently discharged, the battery circuit breakers may not engage individuallydue to the surge current. If this condition is observed, turn off the Meter Alarm Panel power switch,and then engage all the connected battery circuit breakers, the Meter Alarm Panel power switchshould then be turned ON.2Using the DC current probe, measure the current in each of the battery string connections to the bussbars in each battery cabinet. The charge current may initially be high but should quickly reduce in afew minutes if the batteries have a typical new battery charge level.3The current in each string should be approximately equal (+ 5 A).4The bargraph meters on the rectifier modules can be used as a rough estimate of the total batterycharge current. Each rectifier module has eight (8) LEDs to represent the output current. Eachilluminated LED indicates that approximately 12.5% (1/8 or 8.75 A) of the rectifiers maximum (70 A)current is flowing.EXAMPLE:Question: A system fitted with three (3) rectifier modules each have three bargraph LEDsilluminated. What is the total output current into the batteries?Answer: Each bargraph is approximately indicating 12.5% of 70 A, therefore, 3 X 8.75 equals26.25 A. As there are three rectifiers, the total charge current is equal to (3 X 26.25 A) 78.75 A.This charge current calculation only applies at this part of the start up procedure, when the RF Cabinetis not powered on, and the power cabinet heat exchanger is turned off.5Allow a few minutes to ensure that the battery charge current stabilizes before taking any furtheraction. Recheck the battery current in each string. If the batteries had a reasonable charge, the currentin each string should reduce to less than 5 A.6Recheck the DC output voltage. It should remain the same as measured in step 4 of the Power UpTest.NOTEIf discharged batteries are installed, all bargraphs may be illuminated on the rectifiers during thecharge test. This indicates that the rectifiers are at full capacity and are rapidly charging the batteries.It is recommended in this case that the batteries are allowed to charge and stabilize as in the abovestep before commissioning the site. This could take several hours. Battery Discharge TestPerform the test procedure in Table 2-9 only when the battery current isless than 5 A per string. Refer to Table 2-8 on the procedures forchecking current levels.2

The rectifier outputvoltage and current should decrease by approximately 10% as the batteries assume the load. Alarmsfor the Meter Alarm Panel may occur.2Measure the individual battery string current using the DC current probe. The battery dischargecurrent in each string should be approximately the same (within + 5 A).3Turn Battery Test Switch OFF.Failure to turn OFF the Battery Test Switch before leavingthe site, will result in low battery capacity and reducebattery life.CAUTIONHeat Exchanger Power UpTable 2-10: Heat Exchanger Power UpStep Action1Turn the Power Cabinet Heat Exchanger breakers ON (seeFigure 2-6 for breaker location).2The Heat Exchanger will now go into a 5 minute test sequence.

Optimization/Calibration – IntroductionApr 2001 3-1SCt4812ET BTS Optimization/ATP — CDMA LMFDRAFTIntroductionThis chapter provides procedures for downloading system operatingsoftware, set up of the supported test equipment, CSM referenceverification/optimization, and transmit/receive path verification.Before using the LMF, use an editor to view the”CAVEATS” section in the ”readme.txt” file in the c:\wlmffolder for any applicable information.IMPORTANT*Optimization ProcessAfter a BTS is physically installed and the preliminary operations(power up) have been completed, the CDMA LMF is used to calibrateand optimize the BTS. The basic optimization process can beaccomplished as follows:SDownload MGLI2–1 with code and data and then enable MGLI2–1.SUse the status function and verify that all of the installed devices ofthe following types respond with status information: CSM2, BBX2,GLI2, and MCC (and TSU if RFDS is installed). If a device isinstalled and powered up but is not responding and is colored gray inthe BTS display, the device is not listed in the CDF file. The CDF filewill have to be corrected before the device can be accessed by CDMALMF.SDownload code and data to all devices of the following types:–CSM2– BBX–GLI2 (other than MGLI2–1)–MCCSDownload the RFDS TSIC (if installed).SVerify the operation of the GPS and HSO signals.SEnable the following devices (in the order listed):–Secondary CSM (slot 2)–Primary CSM (slot 1)–All MCCsSConnect the required test equipment for a full optimization.SSelect the test equipment.SCalibrate the TX and RX test cables if they have not previously beencalibrated using the CDMA LMF that is going to be used for theoptimization/calibration. The cable calibration values can also beentered manually. . . . continued on next page3
Optimization/Calibration – Introduction – continuedDRAFTSCt4812ET BTS Optimization/ATP — CDMA LMF Apr 20013-2SSelect all of the BBXs and all of the MCCs and use the fulloptimization function. The full optimization function performs TXcalibration, BLO download, TX audit, all TX tests, and all RX testsfor all selected devices.SIf the TX calibration fails, repeat the full optimization for any failedpaths.SIf the TX calibration fails again, correct the problem that caused thefailure and repeat the full optimization for the failed path.SIf the TX calibration and audit portion of the full optimization passesfor a path but some of the TX or RX tests fail, correct the problem thatcaused the failure and run the individual tests as required until all TXand RX tests have passed for all paths.Cell–site TypesSites are configured as Omni/Omni or Sector/Sector (TX/RX). Each typehas unique characteristics and must be optimized accordingly.Cell–site Data File The CDF includes the following information:SDownload instructions and protocolSSite specific equipage informationSC–CCP shelf allocation plan–BBX2 equipage (based on cell–site type) including redundancy–CSM equipage including redundancy–MCC (MCC24E, MCC8E or MCC–1X) channel element allocationplan. This plan indicates how the C–CCP shelf is configured, andhow the paging, synchronization, traffic, and access channelelements (and associated gain values) are assigned among the (up to12) MCCs in the shelf.SCSM equipage including redundancySEffective Rated Power (ERP) table for all TX channels to antennasrespectively. Motorola System Engineering specifies the ERP of atransmit antenna based on site geography, antenna placement, andgovernment regulations. Working from this ERP requirement, theantenna gain, (dependent on the units of measurement specified) andantenna feed line loss can be combined to determine the requiredpower at the top of the BTS frame. The corresponding BBX2 outputlevel required to achieve that power level on any channel/sector canalso be determined.Refer to the CDMA LMF Operator’s Guide, 68P64114A78,for additional information on the layout of the LMFdirectory structure (including CDF file locations andformats).NOTE3
Optimization/Calibration – Introduction – continuedApr 2001 3-3SCt4812ET BTS Optimization/ATP — CDMA LMFDRAFTBTS System SoftwareDownloadBTS system software must be successfully downloaded to the BTSprocessor boards before optimization can be performed. BTS operatingcode is loaded from the LMF computer terminal.Before using the LMF for optimization/ATP, the correctbts–#.cdf and cbsc–#.cdf files for the BTS must beobtained from the CBSC and put in a bts–# folder in theLMF. Failure to use the correct CDF files can cause wrongresults. Failure to use the correct CDF files to log into alive (traffic carrying) site can shut down the site.IMPORTANT*The CDF is normally obtained from the CBSC on a DOS formatteddiskette, or through a file transfer protocol (ftp) if the LMF computer hasftp capability. Refer to the CDMA LMF Operator’s Guide,68P64114A78, or the LMF Help screen, for more information.Site Equipage VerificationIf you have not already done so, use an editor to view the CDF, andreview the site documentation. Verify the site engineering equipage datain the CDF to the actual site hardware.Always wear a conductive, high impedance wrist strapwhile handling any circuit card/module to prevent damageby ESD. Extreme care should be taken during the removaland installation of any card/module. After removal, thecard/module should be placed on a conductive surface orback into the anti–static bag in which it was shipped.CAUTION3
Isolate Span Lines/Connect LMFDRAFTSCt4812ET BTS Optimization/ATP — CDMA LMF Apr 20013-4Isolate BTS from T1/E1 Spans–At active sites, the OMC/CBSC must disable theBTS and place it out of service (OOS). DO NOTremove the span surge protectors until theOMC/CBSC has disabled the BTS.IMPORTANT*Each frame is equipped with one 50–pair punch block for spans,customer alarms, remote GPS, and power cabinet alarms. See Figure 3-2and refer to Table 3-1 for the physical location and pin call–outinformation. To disable the span, pull the surge protectors for therespective span.Before connecting the LMF to the frame LAN, the OMC/CBSC mustdisable the BTS and place it OOS to allow the LMF to control theCDMA BTS. This prevents the CBSC from inadvertently sendingcontrol information to the CDMA BTS during LMF based tests.Configure Channel ServiceUnitThe M–PATH 537 Channel Service Unit (CSU) provides in–bandSNMP–managed digital service access to T1 and fractional T1 lines.M–PATH units plug into the ADC Kentrox 2–slot frame (seeFigure 3-1).Remote M–PATH management is available via SNMP over an in–banddata link on the T1 line (using a facility data link or 8–64 Kbps of a DS0channel). The unit at the near end of the management path can be anSNMP manager or another M–PATH CSU.Each 19 inch rack can support two CSU M–PATH 537 modules. EachM–PATH 537 module supports one and only one span connection.Programming of the M–PATH is accomplished through the DCE 9–pinconnector on the front panel of the CSU shelf. Manuals and a MicrosoftWindows programming disk is supplied with each unit.3

Installing U/Winover–writes these modifications.NOTEThere are multiple binary image packages for installation on the CD–ROM. When prompted, choosethe load that corresponds to the switch release that you currently have installed. Perform the DeviceImages install after the WinLMF installation.If applicable, a separate CD ROM of BTS Binaries may be available for binary updates. CDMA LMF Home DirectoryThe CDMA LMF installation program creates the default home directoryc:\wlmf, and installs the application files and subdirectories (folders)in it. Because this can be changed at installation, the CDMA LMF homedirectory will be referred to with the generic convention of:<x>:\<lmf home directory>Where:<x> = the LMF computer drive letter where the CDMA LMF homedirectory is located.<lmf home directory> = the directory path or name where the CDMALMF is installedThe CDMA LMF installation program creates the defaulthome directory c:\wlmf when the CDMA LMF isinstalled.NOTE3
Preparing the LMF – continuedDRAFTSCt4812ET BTS Optimization/ATP — CDMA LMF Apr 20013-12Copy CBSC CDF Files to theLMF ComputerBefore logging on to a BTS with the LMF to execute optimization/ATPprocedures, the correct bts-#.cdf and cbsc–#.cdf files must be obtainedfrom the CBSC and put in a bts-# folder in the LMF computer. Thisrequires creating versions of the CBSC CDF files on a DOS–formattedfloppy diskette and using the diskette to install the CDF files on theLMF computer.*When copying CDF files, comply with the following toprevent BTS login problems with the LMF.– The numbers used in the bts–#.cdf and cbsc–#.cdffilenames must correspond to the locally assigned numbersfor each BTS and its controlling CBSC.– The generic cbsc–1.cdf file supplied with the LMF willwork with locally numbered BTS CDF files. Using this filewill not provide a valid optimization unless the generic fileis edited to replace default parameters (e.g., channelnumbers) with the operational parameters used locally.IMPORTANTThe procedure in Table 3-4 lists the steps required to transfer the CDFfiles from the CBSC to the LMF computer. For any further information,refer to the CDMA LMF Operator’s Guide (Motorola part number68P64114A21) or the LMF Help screen..Table 3-4: Copying CBSC CDF Files to the LMFStep Action1Login to the CBSC workstation.2Insert a DOS–formatted floppy diskette in the workstation drive.3 Type eject –q and press <Enter>.4 Type mount and press <Enter>.NOTESLook for the “floppy/no_name” message on the last line displayed.SIf the eject command was previously entered, floppy/no_name will be appended with a number. Usethe explicit floppy/no_name reference displayed when performing step 7.5Change to the directory, where the files to be copied reside, by typing cd <directoryname> (e.g., cd bts–248) and pressing <Enter>.6 Type ls and press the Enter key to display the list of files in the directory.. . . continued on next page3
Preparing the LMF – continuedDRAFTApr 2001 3-13SCt4812ET BTS Optimization/ATP — CDMA LMFTable 3-4: Copying CBSC CDF Files to the LMFStep Action7 With Solaris versions of Unix, create DOS–formatted versions of the bts–#.cdf and cbsc–#.cdf fileson the diskette by entering the following command:unix2dos <source filename> /floppy/no_name/<target filename>(e.g., unix2dos bts–248.cdf /floppy/no_name/bts–248.cdf).NOTESOther versions of Unix do not support the unix2dos and dos2unix commands. In these cases, use theUnix cp (copy) command. The copied files will be difficult to read with a DOS or Windows texteditor because Unix files do not contain line feed characters. Editing copied CDF files on the LMFcomputer is, therefore, not recommended.SUsing cp, multiple files can be copied in one operation by separating each filename to be copiedwith a space and ensuring the destination directory (floppy/no_name) is listed at the end of thecommand string following a space (e.g., cp bts–248.cdf cbsc–6.cdf /floppy/na_name)8Repeat steps 5 through 7 for each bts–# that must be supported by the LMF.9When all required files have been copied to the diskette, type eject and press <Enter>.10 Remove the diskette from the CBSC drive.11 If it is not running, start the Windows operating system on the LMF computer.12 Insert the diskette containing the bts–#.cdf and cbsc–#.cdf files into the LMF computer.13 Using Windows Explorer (or equivalent program), create a corresponding bts–# folder in the <lmfhome directory> directory for each bts–#.cdf/cbsc–#.cdf file pair copied from the CBSC.14 Use Windows Explorer (or equivalent program) to transfer the cbsc–#.cdf and bts–#.cdf files from thediskette to the corresponding <lmf home directory>\wlmf\cdma\bts–# folders created in step 13. Creating a NamedHyperTerminal Connection forMMI ConnectionConfirming or changing the configuration data of certain BTS FRUsrequires establishing an MMI communication session between the LMFand the FRU. Using features of the Windows operating system, theconnection properties for an MMI session can be saved on the LMFcomputer as a named Windows HyperTerminal connection. Thiseliminates the need for setting up connection parameters each time anMMI session is required to support optimization.Once the named connection is saved, a shortcut for it can be created onthe Windows desktop. Double clicking the shortcut icon will start theconnection without the need to negotiate multiple menu levels.Follow the procedures in Table 3-5 to establish a named HyperTerminalconnection and create a Windows desktop shortcut for it.3

The CLI environment provides additional capability to theuser to perform manually controlled acceptance tests and audit theresults of optimization and calibration actions.Basic operation of the LMF GUI includes the following:SSelecting and deselecting BTS devicesSEnabling devicesSDisabling devicesSResetting devicesSObtaining device statusSSorting a status report windowFor detailed information on performing these and other LMF operations,refer to the CDMA LMF Operator’s Guide, 68P64114A78.Basic LMF Command LineInterface (CLI) Operation.Both the GUI and the CLI use a program known as the handler. Only onehandler can be running at one time. The architectural design is such thatthe GUI must be started before the CLI if you want the GUI and CLI touse the same handler. When the CLI is launched after the GUI, the CLIautomatically finds and uses an in–progress login session with a BTSinitiated under the GUI. This allows the use of the GUI and the CLI inthe same BTS login session. If a CLI handler is already running whenthe GUI is launched (this happens if the CLI window is already runningwhen the user starts the GUI, or if another copy of the GUI is alreadyrunning when the user starts the GUI), a dialog window displays thefollowing warning message:The CLI handler is already running.This may cause conflicts with the LMF.Are you sure that you want to start the application?This window also contains yes and no buttons. Selecting yes starts theapplication. Selecting no terminates the application.3

Download the BTS – continuedDRAFTSCt4812ET BTS Optimization/ATP — CDMA LMF Apr 20013-30Enable CSMsEach BTS CSM system features two CSM boards per site. In a typicaloperation, the primary CSM locks its Digital Phase Locked Loop(DPLL) circuits to GPS signals. These signals are generated by either anon–board GPS module (RF–GPS) or a remote GPS receiver (R–GPS).The CSM2 card is required when using the R–GPS. The GPS receiver(mounted on CSM 1) is used as the primary timing reference andsynchronizes the entire cellular system. CSM 2 provides redundancy (butdoes not have a GPS receiver).The BTS may be equipped with a LORAN–C LFR, HSO, or external 10MHz Rubidium source which the CSM can use as a secondary timingreference. In all cases, the CSM monitors and determines what referenceto use at a given time.For RF–GPS, verify the CSM configured with the GPSreceiver “daughter board” is installed in the frame’s CSM 1slot before continuing.IMPORTANT*Follow the steps outlined in Table 3-16 to enable the CSMs installed inthe C–CCP shelves.Table 3-16: Enable CSMsStep Action1Click on the target CSM.From the Device pull down, select Enable.NOTEIf equipped with two CSMs, enable CSM–2 firstA status report is displayed confirming change in the device(s) status.Click OK to close the status report window.NOTEFAIL may be shown in the status table for enable action. If Waiting For Phase Lock is shown in theDescription field, the CSM changes to the Enabled state after phase lock is achieved.CSM 1 houses the GPS receiver. The enable sequence can take up to one hour (see below).* IMPORTANTThe GPS satellite system satellites are not in a geosynchronous orbit and are maintained and operatedby the United States Department of Defense (D.O.D.). The D.O.D. periodically alters satellite orbits;therefore, satellite trajectories are subject to change. A GPS receiver that is INS contains an “almanac”that is updated periodically to take these changes into account.If a GPS receiver has not been updated for a number of weeks, it may take up to an hour for the GPSreceiver “almanac” to be updated.Once updated, the GPS receiver must track at least four satellites and obtain (hold) a 3–D position fixfor a minimum of 45 seconds before the CSM will come in service. (In some cases, the GPS receiverneeds to track only one satellite, depending on accuracy mode set during the data load).. . . continued on next page3

CSM System Time – GPS & LFR/HSO VerificationDRAFTSCt4812ET BTS Optimization/ATP — CDMA LMF Apr 20013-32Clock SynchronizationManager System TimeThe primary function of the Clock Synchronization Manager (CSM)boards (slots 1 and 2) is to maintain CDMA system time. The CSM inslot 1 is the primary timing source while slot 2 provides redundancy.The CSM2 card (CSM second generation) is required when using theremote GPS receiver (R–GPS). R–GPS uses a GPS receiver in theantenna head that has a digital output to the CSM2 card. CSM2 can havea daughter card as a local GPS receiver to support an RF–GPS signal.The CSM2 switches between the primary and redundant units (slots 1and 2) upon failure or command. CDMA Clock Distribution Cards(CCDs) buffer and distribute even–second reference and 19.6608 MHzclocks. CCD 1 is married to CSM 1 and CCD 2 is married to CSM 2. Afailure on CSM 1 or CCD 1 cause the system to switch to redundantCSM 2 and CCD 2.Each CSM2 board features an ovenized, crystal oscillator that provides19.6608 MHz clock, even second pulse, and 3 MHz referenced to theselected synchronization source (see Table 3-19):SGPS: local/RF–GPS or remote/R–GPSSLORAN–C Frequency Receiver (LFR) or High Stability Oscillator(HSO)SExternal reference oscillator sourcesFault management has the capability of switching between the GPSsynchronization source and the LFR/HSO backup source in the event ofa GPS receiver failure on CSM 1. During normal operation, the CSM 1board selects GPS as the primary source (see Table 3-19). The sourceselection can also be overridden via the LMF or by the system software.Synchronization between the primary and redundant CSM CCD pairs, aswell as the LFR or HSO back–up to GPS synchronization, increasesreliability.Low Frequency Receiver/High Stability OscillatorThe CSM handles the overall configuration and status monitoringfunctions of the LFR/HSO. In the event of GPS failure, the LFR/HSO iscapable of maintaining synchronization initially established by the GPSreference signal.The LFR requires an active external antenna to receive LORAN RFsignals. Timing pulses are derived from this signal, which issynchronized to Universal Time Coordinates (UTC) and GPS time. TheLFR can maintain system time indefinately after initial GPS lock.3
CSM System Time – GPS & LFR/HSO Verification – continuedApr 2001 3-33SCt4812ET BTS Optimization/ATP — CDMA LMFDRAFTThe HSO is a high stability 10 MHz oscillator with the necessaryinterface to the CSMs. The HSO is typically installed in thosegeographical areas not covered by the LORAN–C system. Since theHSO is a free–standing oscillator, system time can only be maintainedfor 24 hours after 24 hours of GPS lock.Upgrades and Expansions: LFR2/HSO2/HSOXLFR2/HSO2 (second generation cards) both export a timing signal to theexpansion or logical BTS frames. The associated expansion or logicalframes require an HSO–expansion (HSOX) whether the starter frame hasan LFR2 or an HSO2. The HSOX accepts input from the starter frameand interfaces with the CSM cards in the expansion frame. LFR andLFR2 use the same source code in source selection (see Table 3-19).HSO, HSO2, and HSOX use the same source code in source selection(see Table 3-19).Allow the base site and test equipment to warm up for60 minutes after any interruption in oscillator power.CSM board warm-up allows the oscillator oventemperature and oscillator frequency to stabilize prior totest. Test equipment warm-up allows the Rubidiumstandard timebase to stabilize in frequency before anymeasurements are made.NOTE3

Test Set CalibrationDRAFTSCt4812ET BTS Optimization/ATP — CDMA LMF Apr 20013-50BackgroundProper test equipment setup ensures that the test equipment andassociated test cables do not introduce measurement errors, and thatmeasurements are correct.If the test set being used to interface with the BTS has beencalibrated and maintained as a set, this procedure does notneed to be performed. (Test Set includes LMF terminal,communications test set, additional test equipment,associated test cables, and adapters.)NOTEThis procedure must be performed prior to beginning the optimization.Verify all test equipment (including all associated test cables andadapters actually used to interface all test equipment and the BTS) hasbeen calibrated and maintained as a set.If any piece of test equipment, test cable, or RF adapter,that makes up the calibrated test equipment set, has beenreplaced, re-calibration must be performed. Failure to do socan introduce measurement errors, resulting in incorrectmeasurements and degradation to system performance.CAUTIONCalibration of the communications test set (or equivalenttest equipment) must be performed at the site beforecalibrating the overall test set. Calibrate the test equipmentafter it has been allowed to warm–up and stabilize for aminimum of 60 minutes.IMPORTANT*PurposeThese procedures access the CDMA LMF automated calibration routineused to determine the path losses of the supported communicationsanalyzer, power meter, associated test cables, and (if used) antennaswitch that make up the overall calibrated test set. After calibration, thegain/loss offset values are stored in a test measurement offset file on theCDMA LMF.3

A status window is displayed.4Click on OK to close the status report window.Calibrating CablesThe cable calibration function is used to measure the loss (in dB) for theTX and RX cables that are to be used for testing. A CDMA analyzer isused to measure the loss of each cable configuration (TX cableconfiguration and RX cable configuration). The cable calibrationconsists of the following steps.SMeasure the loss of a short cable. This is done to compensate for anymeasurement error of the analyzer. The short cable, which is used onlyfor the calibration process, is used in series with both the TX and RXcable configuration when they are measured. The measured loss of theshort cable is deducted from the measured loss of the TX and RXcable configuration to determine the actual loss of the TX and RXcable configurations. This deduction is done so any error in theanalyzer measurement will be adjusted out of both the TX and RXmeasurements.SThe short cable plus the RX cable configuration loss is measured. TheRX cable configuration normally consists only of a coax cable withtype–N connectors that is long enough to reach from the BTS RX portthe test equipment.SThe short cable plus the TX cable configuration loss is measured. TheTX cable configuration normally consists of two coax cables withtype–N connectors and a directional coupler, a load, and an additionalattenuator if required by the BTS type. The total loss of the path lossof the TX cable configuration must be as required for the BTS(normally 30 or 50 dB). The Motorola Cybertest analyzer is differentin that the required attenuation/load is built into the test set so the TXcable configuration consists only of the required length coax cable.3

Bay Level Offset CalibrationApr 2001 3-59SCt4812ET BTS Optimization/ATP — CDMA LMFDRAFTIntroductionCalibration compensates for normal equipment variations within theBTS and assures maximum measurement accuracy.RF Path Bay Level OffsetCalibrationCalibration identifies the accumulated gain in every transmit path(BBX2 slot) at the BTS site and stores that value in the CAL file. TheBLOs are subsequently downloaded to each BBX2.Each receive path starts at a BTS RX antenna port and terminates at abackplane BBX2 slot. Each transmit path starts at a BBX2 backplaneslot, travels through the LPA, and terminates at a BTS TX antenna port.Calibration identifies the accumulated gain in every transmit path(BBX2 slot) at the BTS site and stores that value in the CAL file. Eachtransmit path starts at a C–CCP shelf backplane BBX2 slot, travelsthrough the LPA, and ends at a BTS TX antenna port. When the TX pathcalibration is performed, the RX path BLO will automatically be set tothe default value.When to Calibrate BLOs Calibration of BLOs is required after initial BTS installation.The BLO data of an operational BTS site must be re-calibrated onceeach year. Motorola recommends re-calibrating the BLO data for allassociated RF paths after replacing any of the following components orassociated interconnecting RF cabling:SBBX2 boardSC–CCP shelfSCIO cardSCIO to LPA backplane RF cableSLPA backplaneSLPASTX filter / TX filter combinerSTX thru-port cable to the top of frame3
Bay Level Offset Calibration – continuedDRAFTSCt4812ET BTS Optimization/ATP — CDMA LMF Apr 20013-60TX Path CalibrationThe TX Path Calibration assures correct site installation, cabling, and thefirst order functionality of all installed equipment. The proper functionof each RF path is verified during calibration. The external testequipment is used to validate/calibrate the TX paths of the BTS.Before installing any test equipment directly to any TXOUT connector you must first verify that there are noCDMA channels keyed. Have the OMC–R place the sectorassigned to the LPA under test OOS. Failure to do so canresult in serious personal injury and/or equipment damage.WARNINGAlways wear a conductive, high impedance wrist strapwhile handling any circuit card/module. If this is not done,there is a high probability that the card/module could bedamaged by ESD.CAUTIONAt new site installations, to facilitate the complete test ofeach CCP shelf (if the shelf is not already fully populatedwith BBX2 boards), move BBX2 boards from shelvescurrently not under test and install them into the emptyBBX2 slots of the shelf currently being tested to insure thatall BBX2 TX paths are tested.–This procedure can be bypassed on operational sitesthat are due for periodic optimization.–Prior to testing, view the CDF file to verify thecorrect BBX2 slots are equipped. Edit the file asrequired to include BBX2 slots not currentlyequipped (per Systems Engineering documentation).IMPORTANT*3

After calibration has been completed, this offset data must bedownloaded to the BBX2s using the Download BLO function. Anexplanation of the file is shown below.Due to the size of the file, Motorola recommends that youprint out a hard copy of a bts.cal file and refer to it for thefollowing descriptions.NOTEThe CAL file is subdivided into sections organized on a per slot basis (aslot Block).Slot 1 contains the calibration data for the 12 BBX2 slots. Slot 20contains the calibration data for the redundant BBX2 (see Table 3-31).Each BBX2 slot header block contains:SA creation Date and Time – broken down into separate parameters ofcreateMonth, createDay, createYear, createHour, and createMin.SThe number of calibration entries – fixed at 720 entries correspondingto 360 calibration points of the CAL file including the slot header andactual calibration data.SThe calibration data for a BBX2 is organized as a large flat array.

Automated Acceptance Test Procedures – OverviewApr 2001 4-1SCt4812ET BTS Optimization/ATP — CDMA LMFDRAFTIntroductionThe Automated Acceptance Test Procedure (ATP) allows MotorolaCellular Field Engineers (CFEs) to run automated acceptance tests on allequipped BTS subsystem devices using the Local Maintenance Facility(LMF) and supported test equipment per the current Cell Site Data File(CDF) assignment.The results of these tests (at the option of the operator) are written to afile that can be printed. All tests are controlled via the LMF platformusing the GPIB interface, therefore, only recommended test equipmentsupported by the LMF can be used.This chapter describes the tests run from the GUI environment, which isthe recommended method. The GUI provides the advantages ofsimplifying the LMF user interface, reducing the potential for miskeyingcommmands and associated parameters, and speeding up the executionof complex operations involving multiple command strings. If you feelthe command line interface (CLI) will provide additional insight into theprogress of ATPs and problems that could possibly be encountered, referto LMF CLI Commands, R15.X (68P09251A59).Before using the LMF, use an editor to view the”CAVEATS” section in the ”readme.txt” file in the c:\wlmffolder for any applicable information.The ATP test is to be performed on out-of-service sectorsonly.DO NOT substitute test equipment with other models notsupported by the LMF.IMPORTANT*Refer to Chapter 3 for detailed information on test setconnections for calibrating equipment, cables and other testset components, if required.NOTECustomer requirements determine which ATP tests to are to beperformed and the field engineer selects the appropriate ATP tests to run.The tests can be run individually or as one of the following groups:SAll TX: TX tests verify the performance of the BTS transmit line up.These include the GLI2, MCC, BBX2, and CIO cards, the LPAs andpassive components including splitters, combiners, bandpass filter,and RF cables. . . . continued on next page4

Automated Acceptance Test Procedure – Overview – continuedDRAFTSCt4812ET BTS Optimization/ATP — CDMA LMF Apr 20014-4Waveform Quality (rho)This test verifies that the transmitted Pilot channel element digitalwaveform quality (rho) exceeds the minimum specified value inANSI–J_STD–019. “Rho” represents the correlation between actual andperfect CDMA modulation spectrum. A rho value of 1.0000 represents100% (or perfect correlation).Pilot Time OffsetThe Pilot Time Offset is the difference between the CDMA analyzermeasurement interval (based on the BTS system time reference) and theincoming block of transmitted data from the BTS (Pilot only, PilotGain = 262, PN Offset = 0).Code Domain PowerThis test verifies code domain power levels, which have been set for allODD numbered Walsh channels, using the OCNS command. This isdone by verifying that the ratio of PILOT divided by OCNS is equal to10.2 + 2 dB, and, that the noise floor of all EVEN numbered “OFF”Walsh channels measures < –27 dB .Frame Error RateThe Frame Error Rate (FER) test verifies RX operation of the entireCDMA Reverse Link using all equipped MCCs assigned to allrespective sector/antennas. The test verifies the BTS sensitivity on alltraffic channel elements currently configured on all equipped MCCs atan RF input level of –119 dBm (or –116 dBm if using TMPC). Followthe procedure in Table 4-1 to perform any ATP test.The STOP button can be used to stop the testing process.NOTETable 4-1: ATP Test ProcedureStep Action1Select the BBX2(s) and MCC(s) to be tested.2From the Tests menu, select the desired test.3Select the appropriate carrier(s) (carrier – bts# – sector# – carrier#) displayed in the Channels/Carrierpick list.To select multiple items, hold down the <Shift> or <Ctrl> key while making the selections.4Type the appropriate channel number in the Carrier n Channels box.The default channel number displayed is determined by the CdmaChans[n] number in the cbsc–n.cdffile for the BTS.5 Click OK.6Follow the cable connection directions as they are displayed.7 Click Save Results or Dismiss to close the status report window. If Dismiss is used the test results will not be saved in the test report file. 4
TX Spectral Purity Transmit Mask Acceptance TestApr 2001 4-5SCt4812ET BTS Optimization/ATP — CDMA LMFDRAFTBackground: Tx Mask TestThis test verifies the spectral purity of each BBX2 carrier keyed up at aspecific frequency, per the current CDF file assignment. All tests areperformed using the external calibrated test set, controlled by the samecommand. All measurements are through the appropriate TX OUT(BTS/RFDS) connector.The Pilot Gain is set to 541 for each antenna and all channel elementsfrom the MCCs are forward-link disabled. The BBX2 is keyed up, usingboth bbxlvl and bay level offsets, to generate a CDMA carrier (with pilotchannel element only). BBX2 power output is set to obtain +40 dBm asmeasured at the TX OUT connector (on either the BTS or RFDSdirectional coupler).TX output power is set to +40 dBm by setting BTS powerlevel to +33.5 dBm to compensate for 6.5 dB increase frompilot gain set to 541.NOTEThe calibrated communications test set measures and returns theattenuation level of all spurious and IM products in a 30 kHz resolutionbandwidth with respect to the mean power of the CDMA channel,measured in a 1.23 MHz bandwidth, in dB, verifying that results meetsystem tolerances at the following test points:S1.9 GHz–at least –45 dB @ + 900 kHz from center frequency–at least –45 dB @ – 900 kHz from center frequencyS800 MHz:–at least –45 dB @ + 750 kHz from center frequencY–at least –45 dB @ – 750 kHz from center frequency–at least –60 dB @ – 1980 kHz from center frequency–at least –60 dB @ – 1980 kHz from center frequencyThe BBX2 then de-keys, and, if selected, the MCC is re-configured toassign the applicable redundant BBX2 to the current TX antenna pathunder test. The test is then repeated.4

All tests are performed using the externalcalibrated test set controlled by the same command. All measurementsare via the appropriate TX OUT (BTS/RFDS) connector.The Pilot Gain is set to 262 for each antenna, and all channel elementsfrom the MCCs will be forward link disabled. The BBX2 is keyed upusing both bbxlvl and bay level offsets, to generate a CDMA carrier(with pilot channel element only, Walsh code 0). BBX2 power output isset to 40 dBm as measured at the TX OUT connector (on either the BTSor RFDS directional coupler).The calibrated communications test set measures and returns the Pilotchannel element digital waveform quality (rho) in dB, verifying thatresult meets system tolerances Waveform quality (rho) should be > 0.912(–0.4 dB).The BBX2 then de-keys and the applicable redundant BBX2 is assignedto the current TX antenna path under test. The test is then repeated.The LMF Tests menu list item, Rho, performs the waveform quality testfor a XCVR(s). All measurements are made through the appropriate TXoutput connector using the calibrated TX cable setup.4
TX Pilot Time Offset Acceptance TestDRAFTSCt4812ET BTS Optimization/ATP — CDMA LMF Apr 20014-8Background: Pilot OffsetAcceptance TestThis test verifies the transmitted Pilot channel element Pilot Time Offsetof each BBX2 carrier keyed up at a specific frequency per the currentCDF file assignment. All tests are performed using the externalcalibrated test set controlled by the same command. All measurementswill be via the appropriate TX OUT (BTS/RFDS) connector.The Pilot Gain is set to 262 for each antenna and all TCH elements fromthe MCCs are forward link disabled. The BBX is keyed up using bothbbxlvl and bay level offsets to generate a CDMA carrier (with pilotchannel element only, Walsh code 0). BBX power output is set to40 dBm as measured at the TX OUT connector (on either the BTS orRFDS directional coupler).The calibrated communications test set measures and returns the PilotTime Offset in uS, verifying results meet system tolerances: Pilot TimeOffset should be within < 3 µs of the target PT Offset (0 mS).The BBX2 then de-keys, and the applicable redundant BBX2 is assignedto the current TX antenna path under test. The test is then repeated.4
TX Code Domain Power Acceptance TestApr 2001 4-9SCt4812ET BTS Optimization/ATP — CDMA LMFDRAFTBackground: Code DomainPower TestThis test verifies the Code Domain Power/Noise of each BBX2 carrierkeyed up at a specific frequency per the current CDF file assignment.All tests are performed using the external calibrated test set controlled bythe same command. All measurements are via the appropriate TX OUT(BTS/RFDS) connector.For each sector/antenna under test, the Pilot Gain is set to 262 and allMCC channel elements under test are configured to generate OrthogonalChannel Noise Source (OCNS) on different odd Walsh codes, and areassigned a full–rate gain of 81. The maximum number of MCC/CEs tobe tested an any one time is 32 (32 odd Walsh codes). If more than 32CEs exist, then multiple sets of measurements are made, so all channelelements are verified on all sectors.BBX2 power output is set to 40 dBm as measured at the TX OUTconnector (on either the BTS or RFDS directional coupler).Code domain power levels, which have been set for all ODD numberedWalsh channels, are verified using the OCNS command. This is done byverifying that Pilot Power (dBm) minus OCNS Power (dBm) is equal to10.2 + 2 dB and that the noise floor of all “OFF” Walsh channelsmeasures < –27 dB (with respect to total CDMA channel power).The BBX2 then de-keys and, the applicable redundant BBX2 is assignedto the current TX antenna path under test. The test is then repeated.Upon completion of the test, OCNS is disabled on the specifiedMCC/CE.4

Troubleshooting: CSM ChecklistApr 2001 6-11SCt4812ET BTS Optimization/ATP — CDMA LMFDRAFTProblem DescriptionMany of the Clock Synchronization Manager (CSM) boards may beresolved in the field before sending the boards to the factory for repair.This section describes known CSM problems identified in field returns,some of which are field-repairable. Check these problems beforereturning suspect CSM boards.Intermittent 19.6608 MHzReference Clock/GPSReceiver Operation If having any problems with CSM board kit numbers, SGLN1145 orSGLN4132, check the suffix with the kit number. If the kit has version“AB,” then replace with version ‘‘BC’’ or higher, and return model ABto the repair center.No GPS Reference SourceCheck the CSM boards for proper hardware configuration. CSM kitSGLN1145, in Slot l, has an on-board GPS receiver; while kitSGLN4132, in Slot 2, does not have a GPS receiver. Any incorrectlyconfigured board must be returned to the repair center. Do not attempt tochange hardware configuration in the field. Also, verify the GPSantenna is not damaged and is installed per recommended guidelines.Checksum Failure The CSM could have corrupted data in its firmware resulting in anon-executable code. The problem is usually caused by either electricaldisturbance, or interruption of data during a download. Attempt anotherdownload with no interruptions in the data transfer. Return CSM boardback to repair center if the attempt to reload fails.GPS Bad RX Message TypeThis is believed to be caused by a later version of CSM software (3.5 orhigher) being downloaded, via LMF, followed by an earlier version ofCSM software (3.4 or lower), being downloaded from the CBSC.Download again with CSM software code 3.5 or higher. Return CSMboard back to repair center if attempt to reload fails.CSM Reference SourceConfiguration Error This is caused by incorrect reference source configuration performed inthe field by software download.

C–CCP Backplane TroubleshootingApr 2001 6-13SCt4812ET BTS Optimization/ATP — CDMA LMFDRAFTIntroductionThe C–CCP backplane is a multi–layer board that interconnects all theC–CCP modules. The complexity of this board lends itself to possibleimproper diagnoses when problems occur.Connector FunctionalityThe following connector overview describes the major types ofbackplane connectors along with the functionality of each. This willallow the Cellular Field Engineer (CFE) to:SDetermine which connector(s) is associated with a specific problemtype.SAllow the isolation of problems to a specific cable or connector.Primary “A” and Redundant “B” ISB (Inter Shelf Bus)connectorsThe 40 pin ISB connectors provide an interface bus from the masterGLI2 to all other GLI2s in the modem frame. Its basic function is toprovide clock synchronization from the master GLI2 to all other GLI2sin the frame.The ISB is also provides the following functions:Sspan line grooming when a single span is used for multiple cages.Sprovide MMI connection to/from the master GLI2 to cell site modem.Sprovide interface between GLI2s and the AMR (for reporting BTSalarms).Span Line ConnectorThe span line input is an 8 pin RJ–45 connector that provides a primaryand secondary (if used) span line interface to each GLI2 in the C–CCPshelf. The span line is used for MM/EMX switch control of the MasterGLI2 and also all the BBX2 traffic.Power Input (Return A, B, and C connectors)Provides a +27 Volt input for use by the power supply modules.Power Supply Module InterfaceEach power supply module has a series of three different connectors toprovide the needed inputs/outputs to the C–CCP backplane. Theseinclude a VCC/Ground input connector, a Harting style multiple pininterface, and a +15 V/Analog Ground output connector. The TransceiverPower Module converts 27/48 Volts to a regulated +15, +6.5, +5.0 Voltsto be used by the C–CCP shelf cards.GLI2 ConnectorThis connector consists of a Harting 4SU digital connector and a6–conductor coaxial connector for RDM distribution. The connectorsprovide inputs/outputs for the GLI2s in the C–CCP backplane.6
CCP Backplane Troubleshooting – continuedDRAFTSCt4812ET BTS Optimization/ATP — CDMA LMF Apr 20016-14GLI2 Ethernet “A” and “B” ConnectionsThese BNC connectors are located on the C–CCP backplane and routedto the GLI2 board. This interface provides all the control and datacommunications between the master GLI2 and the other GLI2, betweengateways, and for the LMF on the LAN.BBX2 ConnectorEach BBX2 connector consists of a Harting 2SU/1SU digital connectorand two 6–conductor coaxial connectors. These connectors provide DC,digital, and RF inputs/outputs for the BBX2s in the C–CCP backplane.CIO ConnectorsSRX RF antenna path signal inputs are routed through RX Tri–Filters(on the I/O plate), and via coaxial cables to the two MPC modules –the six “A” (main) signals go to one MPC; the six “B” (diversity) tothe other. The MPC outputs the low–noise–amplified signals via theC–CCP backplane to the CIO where the signals are split and sent tothe appropriate BBX2.SA digital bus then routes the baseband signal through the BBX2, tothe backplane, then on to the MCC24 slots.SDigital TX antenna path signals originate at the MCC24s. Eachoutput is routed from the MCC24 slot via the backplane appropriateBBX2.STX RF path signal originates from the BBX2, through the backplaneto the CIO, through the CIO, and via multi-conductor coaxial cablingto the LPAs in the LPA shelf.C–CCP BackplaneTroubleshooting ProcedureThe following table provides a standard procedure for troubleshootingproblems that appear to be related to a defective C–CCP backplane. Thetable is broken down into possible problems and steps which should betaken in an attempt to find the root cause.It is important to note that all steps be followed beforereplacing ANY C–CCP backplane.IMPORTANT*6

Itis also assumed that all modules are placed OOS–ROM via the LMFuntil full redundancy of all applicable modules is implemented.The following guidelines should also be noted when using this table.Not every procedure required to bring the site back on lineis indicated in Table B-3. It is meant to be used as aguideline ONLY. The table assumes that the user is familiarenough with the BTS Optimization/ATP procedure tounderstand which test equipment set ups, calibrations, andBTS site preparation will be required before performing theTable # procedures referenced.IMPORTANT*Various passive BTS components (such as the TX and RX directionalcouplers, Preselector IO, CIO; etc.) only call for a TX or RX calibrationaudit to be performed in lieu of a full path calibration. If the RX or TXpath calibration audit fails, the entire RF path calibration will need to berepeated. If the RF path calibration fails, further troubleshooting iswarranted.Whenever any C–CCP BACKPLANE is replaced, it is assumed thatonly power to the C–CCP shelf being replaced is turned off via thebreaker supplying that shelf.Whenever any DISTRIBUTION BACKPLANE is replaced it is assumedthat the power to the entire RFM frame is removed and the PreselectorI/O is replaced. The modem frame should be brought up as if it were anew installation.B

TheBBX2 boards may need to be removed, then re–installed into theiroriginal slots, and re–downloaded (code and BLO data). RX and TXcalibration audits should then be performed.B

Appendix C: BBX2 Gain Set Point vs. BTS Output ConsiderationsApr 2001 C-1SCt4812ET BTS Optimization/ATP — CDMA LMFDRAFTUsage & BackgroundTable C-1 outlines the relationship between the total of all code domainchannel element gain settings (digital root sum of the squares) and theBBX2 Gain Set Point between 33.0 dBm and 44.0 dBm. The resultantRF output (as measured at the top of the BTS in dBm) is shown in thetable. The table assumes that the BBX2 Bay Level Offset (BLO) valueshave been calculated.As an illustration, consider a BBX2 keyed up to produce a CDMAcarrier with only the Pilot channel (no MCCs forward link enabled).Pilot gain is set to 262. In this case, the BBX2 Gain Set Point is shownto correlate exactly to the actual RF output anywhere in the 33 to 44dBm output range.

Appendix E: PN Offset Programming InformationApr 2001 E-1SCt4812ET BTS Optimization/ATP — CDMA LMFDRAFTPN Offset BackgroundAll channel elements transmitted from a BTS in a particular 1.25 MHzCDMA channel are orthonogonally spread by 1 of 64 possible Walshcode functions; additionally, they are also spread by a quadrature pair ofPN sequences unique to each sector.Overall, the mobile uses this to differentiate multiple signals transmittedfrom the same BTS (and surrounding BTS) sectors, and to synchronizeto the next strongest sector.The PN offset per sector is stored on the BBX2s, where thecorresponding I & Q registers reside.The PN offset values are determined on a per BTS/per sector(antenna)basis as determined by the appropriate cdf file content. A breakdown ofthis information is found in Table E-1.PN Offset Usage There are three basic RF chip delays currently in use. It is important todetermine what RF chip delay is valid to be able to test the BTSfunctionality. This can be done by ascertaining if the CDF file FineTxAdj value was set to “on” when the MCC was downloaded with“image data”. The FineTxAdj value is used to compensate for theprocessing delay (approximately 20 mS) in the BTS using any type ofmobile meeting IS–97 specifications.Observe the following guidelines:SIf the FineTxAdj value in the cdf file is 101 (65 HEX), theFineTxAdj has not been set. The I and Q values from the 0 tableMUST be used.If the FineTxAdj value in the cdf file is 213 (D5 HEX), FineTxAdj hasbeen set for the 14 chip table.SIf the FineTxAdj value in the cdf file is 197 (C5 HEX), FineTxAdjhas been set for the 13 chip table.CDF file I and Q values can be represented in DECIMALor HEX. If using HEX, add 0x before the HEX value. Ifnecessary, convert HEX values in Table E-1 to decimalbefore comparing them to cdf file I & Q value assignments.IMPORTANT* . . . continued on next pageE
Appendix E: PN Offset Programming Information – continuedDRAFTSCt4812ET BTS Optimization/ATP — CDMA LMF Apr 2001E-2–If you are using a Qualcomm mobile, use the I and Q values fromthe 13 chip delay table.–If you are using a mobile that does not have the 1 chip offsetproblem, (any mobile meeting the IS–97 specification), use the 14chip delay table.If the wrong I and Q values are used with the wrongFineTxAdj parameter, system timing problems will occur.This will cause the energy transmitted to be “smeared”over several Walsh codes (instead of the single Walsh codethat it was assigned to), causing erratic operation. Evidenceof smearing is usually identified by Walsh channels not atcorrect levels or present when not selected in the CodeDomain Power Test.IMPORTANT* . . . continued on next pageE

IntroductionApr 2001 G-1SCt4812ET BTS Optimization/ATP — CDMA LMFDRAFTPurposeThis procedure is a guide to expanding your system with multiplecarriers while the system remains in service. This procedure also allowsyou to perform on site maintenance (replace defective boards andrecalibrate) while the remainder of the site stays in service.Motorola recommends that you perform this procedure during amaintenance window.This procedure cannot be performed on BTSs with 4–to–1 combiners.The procedure can only be performed on one side of the BTS at onetime. That is, LPAs 1, 2 ,3, 7, 8, 9 (feed antennas 1, 2, 3) can becalibrated while LPAs 6, 7, 8, 10, 11, 12 (feed antennas 4, 5, 6) remainin service and vice versa.Equipment Warm upCalibration of the communications test set (or equivalenttest equipment) must be performed at the site beforecalibrating the overall test set. Calibrate the test equipmentafter it has been allowed to warm-up and stabilize for aminimum of 60 minutes.IMPORTANT*If any piece of test equipment (i.e., test cable, RF adapter)has been replaced, re-calibration must be performed.Failure to do so could introduce measurement errors,causing incorrect measurements and degradation to systemperformance.CAUTIONG
Power Delta CalibrationDRAFTSCt4812ET BTS Optimization/ATP — CDMA LMF Apr 2001G-2Power Delta CalibrationIntroductionThe In–service calibration procedure has several differences from anormal calibration procedure. One of these is the use of a spectrumanalyzer instead of a power meter to measure power. Power meters arebroadband measurement devices and cannot be used to measure powerduring In–service Calibration since other carriers are operating. Aspectrum analyzer can be used because it measures power at a givenfrequency. However, measuring power using a spectrum analyzer is lessaccurate than using a power meter.
