Using CDMA LMFJan 2002 3-31SCt4812ET BTS Optimization/ATP — CDMA LMFBasic LMF OperationThe terms “CDMA LMF” and “WinLMF” areinterchangeableNOTEThe CDMA LMF allows the user to work in the two following operatingenvironments which are accessed using the specified desktop icon:SGraphical User Interface (GUI) using the WinLMF iconSCommand Line Interface (CLI) using the WinLMF CLI iconThe GUI is the primary optimization and acceptance testing operatingenvironment. 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 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 BTSSCt4812ET BTS Optimization/ATP — CDMA LMF Jan 20023-38OverviewBefore a BTS can operate, each equipped device must contain deviceinitialization (ROM) code. ROM code is loaded in all devices duringmanufacture, factory repair, or, for software upgrades, from the CBSCusing the DownLoad Manager (DLM). Device application (RAM) codeand data must be downloaded to each equipped device by the user beforethe BTS can be made fully functional for the site where it is installed.ROM CodeDownloading ROM code to BTS devices from the LMF is NOT routinemaintenance or a normal part of the optimization process. It is onlydone in unusual situations where the resident ROM code release level inthe device is not compatible with the required release level of the siteoperating software and the CBSC can not communicate with the BTS toperform the download. An example would be a BTS loaded with R16.0software where a GLI which is factory–loaded with R9.2.x or earlierROM code must be installed to replace a malfunctioning GLI.Before ROM code can be downloaded from the LMF, the correct ROMcode file for each device to be loaded must exist on the LMF computer.ROM code must be manually selected for download.ROM code can be downloaded to a device that is in any state. After thedownload is started, the device being downloaded will change toOOS_ROM (blue). The device will remain OOS_ROM (blue) when thedownload is completed. A compatible revision–level RAM code mustthen be downloaded to the device. Compatible code loads for ROM andRAM must be used for the device type to ensure proper performance.The compatible device code release levels for the BSS software releasebeing used are listed in the Version Matrix section of the SCt CDMARelease Notes (supplied on the tape or CD–ROM containing the BSSsoftware).Procedures to load ROM code are located in Appendix J.RAM CodeBefore RAM code can be downloaded from the LMF, the correct RAMcode file for each device must exist on the LMF computer. RAM codecan be automatically or manually selected depending on the Devicemenu item chosen and where the RAM code file for the device is storedin the LMF file structure. The RAM code file will be selectedautomatically if the file is in the <x>:\<lmf homedirectory>\cdma\loads\n.n.n.n\code folder (where n.n.n.n is thedownload code version number that matches the “NextLoad” parameterof the CDF file). The RAM code file in the code folder must have thecorrect hardware bin number for the device to be loaded.RAM code can be downloaded to a device that is in any state. After thedownload is started, the device being loaded will change to OOS_ROM(blue). When the download is completed successfully, the device willchange to OOS_RAM (yellow).3$

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. The HSOX is used for expansion frames. In all cases, theCSM monitors and determines what reference to 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 3-23 to enable the CSMs installed inthe C–CCP shelves.Table 3-23: 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 VerificationJan 2002 3-45SCt4812ET BTS Optimization/ATP — CDMA LMFClock 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 3-26):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 3-26). 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.LFR/HSOThe 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 – continuedSCt4812ET BTS Optimization/ATP — CDMA LMF Jan 20023-46The 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 frames. The associated expansion frames require anHSO–expansion (HSOX) whether the starter frame has an LFR2 or anHSO2. The HSOX accepts input from the starter frame and interfaceswith the CSM cards in the expansion frame. LFR and LFR2 use thesame source code in source selection (see Table 3-26). HSO, HSO2, andHSOX use the same source code in source selection (see Table 3-26).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 CalibrationJan 2002 3-73SCt4812ET BTS Optimization/ATP — CDMA LMFBackgroundProper 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

Test Set Calibration – continuedSCt4812ET BTS Optimization/ATP — CDMA LMF Jan 20023-74GPIB AddressesGPIB addresses can range from 1 through 30. The LMF will accept anyaddress in that range, but the numbers entered in the LMF Optionswindow GPIB address box must match the addresses of the testequipment. Motorola recommends using 1 for a CDMA signal generator,13 for a power meter, and 18 for a communications system analyzer. Toverify and, if necessary, change the GPIB addresses of the testequipment, refer to the Setting GPIB Addresses section of Appendix F.Selecting Test EquipmentUse LMF Options from the Options menu list to select test equipmentautomatically (using the autodetect feature) or manually.PrerequisitesA Serial Connection and a Network Connection tab are provided fortest equipment selection. The Serial Connection tab is used when thetest equipment items are connected directly to the CDMA LMFcomputer via a GPIB box (normal setup). The Network Connection tabis used when the test equipment is to be connected remotely via anetwork connection.Ensure the following has been completed before selecting testequipment:STest equipment is correctly connected and turned on.SCDMA LMF computer serial port and test equipment are connected tothe GPIB box.Manually Selecting TestEquipment in a SerialConnection TabTest equipment can be manually specified before, or after, the testequipment is connected. CDMA LMF does not check to see if the testequipment is actually detected for manual specification.Table 3-30: Selecting Test Equipment Manually in a Serial Connection TabStep Action1From the Tools menu, select Options.The LMF Options window appears.2Click on the Serial Connection tab (if not in the forefront).3Select the correct serial port in the COMM Port pick list (normally COM1).4Click on the Manual Specification button (if not enabled).5Click on the check box corresponding to the test item(s) to be used.3

The address for a signalgenerator is normally 1, a power meter is normally 13 and the address for a CDMA analyzer isnormally 18. If 1, 13,18 are included in the GPIB addresses to search box, the power meter (13) willbe used for RF power measurements. If the test equipment items are manually selected the CDMAanalyzer is used only if a power meter is not selected.6 Click Apply. The button will darken until the selection has been committed.

A Directions window is displayed. Followthe instructions provided.2Follow the direction provided.3Click on Continue to close the Directions window. 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 procedures.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.SMeasure the short cable plus the RX cable configuration loss ismeasured. The RX cable configuration normally consists only of acoax cable with type–N connectors that is long enough to reach fromthe BTS RX port the test equipment.SMeasure the short cable plus the TX cable configuration loss ismeasured. The TX cable configuration normally consists of two coaxcables with type–N connectors and a directional coupler, a load, andan additional attenuator if required by the BTS type. The total loss ofthe path loss of the TX cable configuration must be as required for theBTS (normally 30 or 50 dB). The Motorola Cybertest analyzer isdifferent in that the required attenuation/load is built into the test setso the TX cable configuration consists only of the required lengthcoax cable.3

Bay Level Offset CalibrationJan 2002 3-83SCt4812ET BTS Optimization/ATP — CDMA LMFIntroductionCalibration 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 (BBXslot) at the BTS site and stores that value in the CAL file. The BLOs aresubsequently downloaded to each BBX.Each receive path starts at a BTS RX antenna port and terminates at abackplane BBX slot. Each transmit path starts at a BBX backplane slot,travels through the LPA, and terminates at a BTS TX antenna port.Calibration identifies the accumulated gain in every transmit path (BBXslot) at the BTS site and stores that value in the CAL file. Each transmitpath starts at a C–CCP shelf backplane BBX slot, travels through theLPA, and ends at a BTS TX antenna port. When the TX path calibrationis performed, the RX path BLO will automatically be set to the defaultvalue.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:SBBX 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 – continuedSCt4812ET BTS Optimization/ATP — CDMA LMF Jan 20023-84TX 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 BBX boards), move BBX boards from shelvescurrently not under test and install them into the emptyBBX slots of the shelf currently being tested to insure thatall BBX 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 BBX slots are equipped. Edit the file asrequired to include BBX slots not currently equipped(per Systems Engineering documentation).IMPORTANT*3

Bay Level Offset Calibration – continuedJan 2002 3-85SCt4812ET BTS Optimization/ATP — CDMA LMFBLO Calibration Data FileDuring the calibration process, the LMF creates a calibration (BLO) datafile. After calibration has been completed, this offset data must bedownloaded to the BBXs 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 BBX slots. Slot 20contains the calibration data for the redundant BBX (see Table 3-39).Each BBX 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 BBX is organized as a large flat array. Thearray is organized by branch, BBX slot, and calibration point.–The first breakdown of the array indicates which branch thecontained calibration points are for. The array covers transmit, mainreceive and diversity receive offsets as follows:Table 3-38: BLO BTS.cal file Array Branch AssignmentsRange AssignmentC[1]–C[240] TransmitC[241]–C[480] ReceiveC[481]–C[720] Diversity Receive3

BBX slot 1’s 10 calibrationpoints are sent (C[1] – C[20]), followed by BBX slot 2’s 10calibration points (C[21] – C[40]), etc. The RxCal data is sent next,followed by the RxDCal data.STemperature compensation data is also stored in the cal file for eachslot.Test Equipment Setup:RF Path CalibrationFollow the steps in Table 3-40 to set up test equipment.Table 3-40: Test Equipment Setup (RF Path Calibration)Step ActionNOTEVerify the GPIB is properly connected and turned on.! CAUTIONTo prevent damage to the test equipment, all transmit (TX) test connections must be via the 30 dBdirectional coupler for 800 MHz or via a 30 dB coupler with a 20 dB in–line attenuator for 1900 MHz.1Connect the LMF computer terminal to the BTS LAN A connector on the BTS (if you have notalready done so). Refer to the procedure in Table 3-6.SIf required, calibrate the test equipment per the procedure in Table 3-32.SConnect the test equipment as shown in Figure 3-17, Figure 3-18 and Figure 3-19.3

Bay Level Offset Calibration – continuedSCt4812ET BTS Optimization/ATP — CDMA LMF Jan 20023-88Transmit (TX) Path CalibrationThe assigned channel frequency and power level (as measured at the topof the frame) for transmit calibration is derived from the site CDF file.For each BBX, the channel frequency is specified in the ChannelListCDF file parameter and the power is specified in the SIFPilotPwrCDF file parameter for the sector associated with the BBX (locatedunder the ParentSECTOR field of the ParentCARRIER CDF fileparameter).The calibration procedure attempts to adjust the power to within +0.5 dBof the desired power. The calibration will pass if the error is less than+1.5 dB.The TX Bay Level Offset at sites WITHOUT the directional coupleroption, is approximately 42.0 dB ±3.0 dB.SAt sites WITHOUT RFDS option, BLO is approximately 42.0 dB ±4.0 dB. A typical example would be TX output powermeasured at BTS (36.0 dBm) minus the BBX TX output level(approximately –6.0 dBm) would equate to 42 dB BLO.The TX Bay Level Offset at sites WITH the directional coupler option,is approximately 41.4 dB ±3.0 dB. TX BLO = Frame Power Outputminus BBX output level.SExample: TX output power measured at RFDS TX coupler(39.4 dBm) minus the BBX TX output level (approximately–2.0 dBm) and RFDS directional coupler/cable (approximately–0.6 dBm) would equate to 41.4 dB BLO.The LMF Tests menu list items, TX Calibration and All Cal/Audit,perform the TX BLO Calibration test for a XCVR(s). The All Cal/Auditmenu item performs TX calibration, downloads BLO, and performs TXaudit if the TX calibration passes. All measurements are made throughthe appropriate TX output connector using the calibrated TX cable setup.Test Pattern Drop–down Pick ListPilot is shown as the default setting in this pick list box.

After the actual TXcalibration is completed during either the TX Calibration or AllCal/Audit process, the BLO derived from the calibration is compared toa standard, acceptable BLO tolerance for the BTS. In some installations,additional items may be installed in the transmit path. The additionalchange in gain from these items could cause BLO verification failureand, therefore, failure of the entire calibration. In these cases, either theVerify BLO checkbox should be unchecked or the additional path lossesshould be added into each applicable sector using the Util>Edit>TX Coupler Loss function.Single–Sided BLONormally valid values are some value plus–or–minus some offset.

RFDS Setup and Calibration – continuedJan 2002 3-105SCt4812ET BTS Optimization/ATP — CDMA LMFRFDS CalibrationThe RFDS Calibration option is used to calibrate the RFDS TX and RXpaths.TX Path Calibration – For a TX antenna path calibration the BTSXCVR is keyed at a pre–determined power level and the BTS poweroutput level is measured by the RFDS. The power level is then measuredat the TX antenna directional coupler by the power measuring testequipment item being used (power meter or analyzer). The difference(offset) between the power level at the RFDS and the power level at theTX antenna directional coupler is used as the TX RFDS calibrationoffset value.RX Path Calibration – For an RX antenna path calibration the RFDS iskeyed at a pre–determined power level and the power input level ismeasured by the BTS BBX. A CDMA signal at the same power levelmeasured by the BTS BBX is then injected at the RX antenna directionalcoupler by the communications system analyzer. The difference (offset)between the RFDS–keyed power level and power level measured at theBTS BBX is the RFDS RX calibration offset value.RFDS calibration and the CAL file – The TX and RX RFDScalibration offset values are written to the CAL file in the slot[385]Block.TSIC channel frequency – For each RFDS TSIC, the channelfrequency is determined at the lower third and upper third of theappropriate band using the frequencies listed in Table 3-51.Table 3-51: RFDS TSIC Calibration Channel FrequenciesSystem Channel Calibration Points800 MHz (A and B) 341 and 6821.9 GHz 408 and 791Before installing any test equipment directly to any TXOUT connector, verify that there are no CDMA channelskeyed.

$Automated Acceptance Test Procedures – OverviewJan 2002 4-1SCt4812ET BTS Optimization/ATP — CDMA LMFIntroductionThe Automated Acceptance Test Procedure (ATP) allows MotorolaCellular Field Engineers (CFEs) to run automated acceptance tests on allequipped BTS subsystem devices using the Local Maintenance Facility(LMF) and supported test equipment per the current Cell Site Data File(CDF) assignment.The results of these tests (at the option of the operator) are written to afile that can be printed. All tests are controlled via the LMF platformusing the GPIB interface, therefore, only recommended test equipmentsupported by the LMF can be used.This chapter describes the tests run from the GUI environment, which isthe recommended method. The GUI provides the advantages ofsimplifying the LMF user interface, reducing the potential for miskeyingcommmands and associated parameters, and speeding up the executionof complex operations involving multiple command strings. If you feelthe command line interface (CLI) will provide additional insight into theprogress of ATPs and problems that could possibly be encountered, referto LMF CLI Commands.Before using the LMF, use an editor to view the”CAVEATS” section in the ”readme.txt” file in the c:\wlmffolder for any applicable information.The ATP test is to be performed on out-of-service sectorsonly.DO NOT substitute test equipment with other models notsupported by the LMF.IMPORTANT*4$
