Preparing the LMF 68P09258A31–AOct 20031X SCt 4812T BTS Optimization/ATP3-10LMF Operating System InstallationThis section provides information and instructions for installing andupdating the LMF software and files.NOTE First Time Installation Sequence:1. Install Java Runtime Environment (JRE)2. Install U/WIN K–shell emulator3. Install LMF application programs4. Install/create BTS foldersNOTE Any time you install U/WIN, you must install the LMF softwarebecause the installation of the LMF modifies some of the filesthat are installed during the U/Win installation. Installing U/Winover–writes these modifications.There are multiple binary image packages for installation on theCD–ROM. When prompted, choose the load that corresponds tothe switch release that you currently have installed. Perform theDevice Images install after the WinLMF installation.If applicable, a separate CD ROM of BTS Binaries may beavailable for binary updates.Follow the procedure in Table 3-1 to install the LMF applicationprogram using the LMF CD ROM.Table 3-1: Install LMF using CD ROMnStep Action1Insert the LMF CD ROM disk into your disk drive and perform thefollowing as required:1a – If the Setup screen appears, follow the instructions displayed onthe screen.1b – If the Setup screen is not displayed, proceed to Step 2.2Click on the Start button.3 Select Run.4 Enter d:\autorun in the Open box and click OK.NOTEIf applicable, replace the letter d with the correct CD ROM driveletter. 3
Preparing the LMF68P09258A31–AOct 2003 1X SCt 4812T BTS Optimization/ATP 3-11Copy BTS and CBSC CDF (or NECF) Files to the LMF ComputerBefore logging on to a BTS with the LMF computer to executeoptimization/ATP procedures, the correct bts-#.cdf (or bts–#.necf) andcbsc-#.cdf files must be obtained from the CBSC and put in a bts-#folder in the LMF computer. This requires creating versions of theCBSC CDF files on a DOS–formatted floppy diskette and using thediskette to install the CDF files on the LMF computer.NOTE – If the LMF has ftp capability, the ftp method can be used tocopy the CDF or NECF files from the CBSC.– On Sun OS workstations, the unix2dos command can beused in place of the cp command (e.g., unix2dosbts–248.cdf bts–248.cdf). This should be done using a copyof the CBSC CDF file so the original CBSC CDF file isnot changed to DOS format.NOTE When copying CDF or NECF files, comply with the followingto prevent BTS login problems with the Windows LMF:SThe numbers used in the bts-#.cdf (or bts–#.necf) andcbsc-#.cdf filenames must correspond to the locally-assignednumbers for each BTS and its controlling CBSC.SThe generic cbsc–1.cdf file supplied with the Windows LMFwill work with locally numbered BTS CDF files. Using thisfile will not provide a valid optimization unless the genericfile is edited to replace default parameters (e.g., channelnumbers) with the operational parameters used locally.The procedure in Table 3-2 lists the steps required to transfer the CDFfiles from the CBSC to the LMF computer. For further information, referto the LMF Help function on–line documentation.Table 3-2: Copying CDF or NECF Files to the LMF ComputernStep ActionAT THE CBSC:1Login to the CBSC workstation.2Insert a DOS–formatted floppy diskette in the workstation drive.3 Type eject –q and press the Enter key.4 Type mount and press the Enter key.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.Use the 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 the Enter key.6 Type ls and press the Enter key to display the list of files in the directory.. . . continued on next page3
Preparing the LMF 68P09258A31–AOct 20031X SCt 4812T BTS Optimization/ATP3-12Table 3-2: Copying CDF or NECF Files to the LMF ComputernActionStep7 With Solaris versions of Unix, create DOS–formatted versions of the bts-#.cdf (or bts–#.necf) andcbsc-#.cdf files on 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, usethe Unix 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/no_name).8Repeat Steps 5 through 7 for each bts–# that must be supported by the LMF computer.9When all required files have been copied to the diskette type eject and press the Enter key.10 Remove the diskette from the CBSC drive.AT THE LMF:11 If it is not running, start the Windows operating system on the LMF computer.12 Insert the diskette containing the bts-#.cdf (or bts–#.necf) and cbsc-#.cdf files into the LMFcomputer.13 Using MS Windows Explorer, create a corresponding bts–# folder in the <x>:\<lmf homedirectory>\cdma directory for each bts-#.cdf (or bts–#.necf) and cbsc-#.cdf file pair copied from theCBSC.14 Use MS Windows Explorer to transfer the bts-#.cdf (or bts–#.necf) and cbsc-#.cdf files from thediskette to the corresponding <x>:\<lmf home directory>\cdma\bts–# folders created in Step 13. 3

Span Lines – Interface and Isolation68P09258A31–AOct 2003 1X SCt 4812T BTS Optimization/ATP 3-15Span Lines – Interface and IsolationT1/E1 Span InterfaceNOTE At active sites, the OMC/CBSC must disable the BTS and placeit out of service (OOS). DO NOT remove the 50–pin TELCOcable connected to the BTS frame site I/O board J1 connectoruntil the OMC/CBSC has disabled the BTS!Each frame is equipped with one Site I/O and two Span I/O boards. TheSpan I/O J1 connector provides connection of 25 pairs of wire. A GLIcard can support up to six spans. In the SC 4812T configuration, the oddspans (1, 3, and 5) terminate on the Span “A” I/O; and the even spans (2,4, and 6) terminate on the Span “B” I/O.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. Refer toFigure 3-2 and Figure 3-3 as required.Isolate BTS from T1/E1 SpansOnce the OMC–R/CBSC has disabled the BTS, the spans must bedisabled to ensure the LMF will maintain control of the BTS. To disablethe spans, disconnect the span cable connectors from the Span I/O cards(see Figure 3-2).Figure 3-2: Span I/O Board T1 Span Isolation50–PIN TELCOCONNECTORSREMOVEDSPAN A CONNECTOR(TELCO) INTERFACETO SPAN LINESSPAN B CONNECTOR(TELCO) INTERFACETO SPAN LINESTOP of Frame (Site I/O and Span I/O boards)RS–232 9–PIN SUB DCONNECTOR SERIALPORT FOR EXTERNALDIAL UP MODEMCONNECTION (IF USED)FW002993

All references tothe LMF in this publication are to the CDMA portion of the program.Operating Environments – The LMF application program allows theuser to work in the two following operating environments which areaccessed using the specified desktop icons:SGraphical User Interface (GUI) using the WinLMF iconSCommand Line Interface (CLI) using the WinLMF CDMA 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 – Basic operation of the LMF in either environmentincludes performing the following:SSelecting and deselecting BTS devicesSEnabling devicesSDisabling devicesSResetting devicesSObtaining device statusThe following additional basic operation can be performed in a GUIenvironment:SSorting a status report windowFor detailed information on performing these and other LMF operations,refer to the LMF Help function on–line documentation.NOTE Unless otherwise noted, LMF procedures in this manual areperformed using the GUI environment.3
Using the LMF68P09258A31–AOct 2003 1X SCt 4812T BTS Optimization/ATP 3-19The LMF Display and the BTSBTS Display – When the LMF is logged into a BTS, a frame tab isdisplayed for each BTS frames. The frame tab will be labeled with“CDMA” and the BTS number, a dash, and the frame number (forexample, BTS–812–1 for BTS 812, RFMF 1). If there is only one framefor the BTS, there will only be one tab.CDF/NECF Requirements – For the LMF to recognize the devicesinstalled in the BTS, a BTS CDF/NECF file which includes equipageinformation for all the devices in the BTS must be located in theapplicable <x>:\<lmf home directory>\cdma\bts–# folder. To providethe necessary channel assignment data for BTS operation, a CBSC CDFfile which includes channel data for all BTS RFMFs is also required inthe folder.RFDS Display – If an RFDS is included in the CDF/NECF file, anRFDS tab labeled with “RFDS,” a dash and the BTS number–framenumber combination (for example, RFDS–812–1) will be displayed.Graphical User Interface OverviewThe LMF uses a GUI, which works in the following way:SSelect the device or devices.SSelect the action to apply to the selected device(s).SWhile action is in progress, a status report window displays the actiontaking place and other status information.SThe status report window indicates when the the action is completeand displays other pertinent information.SClicking the OK button closes the status report window.3
Using the LMF 68P09258A31–AOct 20031X SCt 4812T BTS Optimization/ATP3-20Understanding GUI OperationThe following screen captures are provided to help understand how theGUI operates:– Figure 3-4 depicts the differences between packet and circuitCDMA “cdf” file identification. Note that if there is a packetversion “bts” file, the “(P)” is added as a suffix. There is acorresponding “(C)” for the circuit mode version.– Figure 3-5 depicts the Self-Managed Network Elements (NEs) stateof a packet mode SC4812T. Note that an “X” is on the front of eachcard that is under Self–Managed Network Elements (NEs) controlby the GLI3 card.– Figure 3-6 depicts three of the available packet mode commands.Normally the GLI3 has Self-Managed Network Elements (NEs)control of all cards as shown in Figure 3-5 by an “(X)”. In that statethe LMF may only status a card. In order to download code or test acard, the LMF must request Self-Managed Network Elements (NEs)control of the card by using the shown dropdown menu. It also usesthis menu to release control of the card back to the GLI3. The GLI3will also assume control of the cards after the LMF logs out of theBTS. The packet mode GLI3 normally is loaded with a tape releaseand NECB and NECJ files which point to a tape release stored onthe GLI3. When the GLI3 has control of a card it will maintain thatcard with the code on that tape release.– Figure 3-7 depicts a packet mode site that has the MCC–1 and theBBX–1 cards under LMF control. Notice that the “X” is missingfrom the front of these two cards.For detailed information on performing these and other LMF operations,refer to the LMF Help function on–line documentation.3

Using the LMF68P09258A31–AOct 2003 1X SCt 4812T BTS Optimization/ATP 3-25Command Line Interface OverviewThe LMF also provides Command Line Interface (CLI) capability.Activate the CLI by clicking on a shortcut icon on the desktop. The CLIcan not be launched from the GUI, only from the desktop icon.Both the GUI and the CLI use a program known as the handler. Only onehandler can be running at one time. Due to architectural limitations, theGUI must be started before the CLI if you want the GUI and CLI to usethe 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 you want to start the application? Yes NoThis window also contains Yes and No buttons. Selecting Yes starts theapplication. Selecting No terminates the application.CLI Format ConventionsThe CLI command syntax is as follows:SverbSdevice including device identifier parametersSswitchSoption parameters consisting of:– keywords– equals signs (=) between the keywords and the parameter values– parameter valuesSpaces are required between the verb, device, switch, and optionparameters. A hyphen is required between the device and its identifiers.Following is an example of a CLI command.measure bbx–<bts_id>–<bbx_id> rssi channel=6 sector=5Refer to LMF CLI Commands for a complete explanation of the CLIcommands and their usage.3

An LMF session can be logged into only one BTS at atime.PrerequisitesBefore attempting to log into a BTS, ensure the following have beencompleted:SThe LMF is correctly installed on the LMF computer.SA bts-nnn folder with the correct CDF/NECF and CBSC files exists.SThe LMF computer was connected to the BTS before starting theWindows operating system and the LMF software. If necessary, restartthe computer after connecting it to the BTS in accordance withTable 3-5 and Figure 3-3.CAUTION Be sure that the correct bts–#.cdf/necf and cbsc–#.cdf file areused for the BTS. These should be the CDF/NECF files that areprovided for the BTS by the CBSC. Failure to use the correctCDF/NECF files can result in invalid optimization. Failure touse the correct CDF/NECF files to log into a live(traffic–carrying) site can shut down the site.BTS Login from the GUI EnvironmentFollow the procedure in Table 3-6 to log into a BTS when using the GUIenvironment.Table 3-6: BTS GUI Login ProcedurenStep Action1Start the CDMA LMF GUI environment by double clicking on the WinLMF desktop icon (if theLMF is not running).NOTEIf a warning similar to the following is displayed, select No, shut down other LMF sessions whichmay be running, and start the CDMA LMF GUI environment again:The CLI handler is already running.This may cause conflicts with the LMF.Are you sure you want to start the application?Yes No2Click on the Login tab (if not displayed).3If no base stations are displayed in the Available Base Stations pick list, double click on theCDMA icon.4Click on the desired BTS number.

ROM code is loaded in all devices duringmanufacture or 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 nor a normal part of the optimization process. It is onlydone in unusual situations where the resident ROM code in the devicedoes not match the release level of the site operating software AND theCBSC cannot communicate with the BTS to perform the download.If you must download ROM code, the procedures are located inAppendix G.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.NOTE The ROM code file is not available for GLI3s. GLI3s are ROMcode loaded at the factory.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).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 downloaded changes to OOS-ROM(blue). When the download is completed successfully, the device willchange to OOS-RAM (yellow).3

The download code procedure is required inthe event it becomes necessary to code load CSMs withupdated software versions. Use the status function todetermine the current code load versions.– The CSM(s) to be enabled must have been downloadedwith code (Yellow, OOS–RAM) and data.Each 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 the primary timing reference and synchronizesthe entire cellular system. CSM–2 provides redundancy but does nothave a GPS receiver.The BTS may be equipped with a remote GPS, LORAN–C LFR, HSO10 MHz Rubidium source, or HSOX for expansion frames, which theCSM can use as a secondary timing reference. In all cases, the CSMmonitors and determines what reference to use at a given time.Follow the procedure in Table 3-16 to enable the CSMs.Table 3-16: Enable CSMsnStep Action1Click on the target CSM (CSM–2 first, if equipped with two CSMs).2From the Device pull down, select Enable.– A status report is displayed confirming change in the device(s) status.– Click OK to close the status report window.NOTE– The board in slot CSM 1 interfaces with the GPS receiver. The enable sequence for this board cantake up to one hour (see below).– FAIL may be shown in the status report table for a slot CSM 1 enable action. If Waiting For PhaseLock is shown in the Description field, the CSM changes to the Enabled state after phase lock isachieved.* IMPORTANT– The GPS satellite system satellites are not in a geosynchronous orbit and are maintained andoperated by the United States Department of Defense (D.O.D.). The D.O.D. periodically alterssatellite orbits; therefore, satellite trajectories are subject to change. A GPS receiver that is INScontains 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 theGPS receiver “almanac” to be updated.– Once updated, the GPS receiver must track at least four satellites and obtain (hold) a 3–D positionfix for a minimum of 45 seconds before the CSM will come in service. (In some cases, the GPSreceiver needs to track only one satellite, depending on accuracy mode set during the data load).. . . continued on next page3

CSM System Time – GPS & LFR/HSO Verification68P09258A31–AOct 2003 1X SCt 4812T BTS Optimization/ATP 3-43CSM System Time – GPS & LFR/HSO VerificationCSM & LFR BackgroundThe 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. TheCSM2 card (CSM second generation) is required when using the remoteGPS receiver (R–GPS). R–GPS uses a GPS receiver in the antenna headthat has a digital output to the CSM2 card. CSM2 can have a daughtercard 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 DistributionCards (CCDs) buffer and distribute even–second reference and 19.6608MHz clocks. CCD–1 is married to CSM–1 and CCD–2 is married toCSM 2. A failure on CSM–1 or CCD–1 cause the system to switch toredundant CSM–2 and CCD–2.In a typical operation, the primary CSM locks its Digital Phase LockedLoop (DPLL) circuits to GPS signals. These signals are generated byeither an on–board GPS module (RF–GPS) or a remote GPS receiver(R–GPS). The CSM2 card is required when using the R–GPS. DPLLcircuits employed by the CSM provide switching between the primaryand redundant unit upon request. Synchronization between the primaryand redundant CSM cards, as well as the LFR or HSO back–up source,provides excellent reliability and performance.Each CSM board features an ovenized, crystal oscillator that provides19.6608 MHz clock, even second tick reference, and 3 MHz sinewavereference, referenced to the selected synchronization source (GPS,LORAN–C Frequency Receiver (LFR), or High Stability Oscillator(HSO), T1 Span, or external reference oscillator sources).The 3 MHz signals are also routed to the RDM EXP 1A & 1Bconnectors on the top interconnect panel for distribution to co–locatedframes at the site.Fault 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 3-20). The sourceselection can also be overridden via the LMF or by the system software.Front Panel LEDsThe status of the LEDs on the CSM boards are as follows:SSteady Green – Master CSM locked to GPS or LFR (INS).SRapidly Flashing Green – Standby CSM locked to GPS or LFR(STBY).SFlashing Green/Rapidly Flashing Red – CSM OOS–RAM attemptingto lock on GPS signal.SRapidly Flashing Green and Red – Alarm condition exists. TroubleNotifications (TNs) are currently being reported to the GLI.3

In theevent of GPS failure, the LFR/HSO is capable of maintainingsynchronization initially established by the GPS reference signal.LFR – The LFR requires an active external antenna to receiveLORAN–C RF signals. Timing pulses are derived from this signal,which is synchronized to Universal Time Coordinates (UTC) and GPStime. The LFR can maintain system time indefinitely after initial GPSlock.HSO – The 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 lockUpgrades 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).NOTE Allow the base site and test equipment to warm up for 60minutes after any interruption in oscillator power. CSM boardwarm-up allows the oscillator oven temperature and oscillatorfrequency to stabilize prior to test. Test equipment warm-upallows the Rubidium standard timebase to stabilize in frequencybefore any measurements are made.3

Test Set Calibration 68P09258A31–AOct 20031X SCt 4812T BTS Optimization/ATP3-74Test Set CalibrationBackgroundProper test equipment calibration ensures that the test equipment andassociated test cables do not introduce measurement errors, and thatmeasurements are correct.NOTE If the test equipment set being used to optimize or test the BTShas been calibrated and maintained as a set, this procedure doesnot need to be performed.This 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.CAUTION If any piece of test equipment, test cable, or RF adapter thatmakes up the calibrated test equipment set has been replaced, theset must be re-calibrated. Failure to do so can introducemeasurement errors, resulting in incorrect measurements anddegradation to system performance. Motorola recommendsrepeating cable calibration before testing at each BTS site.NOTE Calibration of the communications system analyzer (orequivalent test equipment) must be performed at the site beforecalibrating the overall test equipment set. Calibrate the testequipment after it has been allowed to warm–up and stabilize fora minimum of 60 minutes.Calibration Procedures IncludedAutomaticProcedures included in this section use the LMF automated calibrationroutine to determine path losses of the supported communicationsanalyzer, power meter, associated test cables, adapters, and (if used)antenna switch that make up the overall calibrated test equipment set.After calibration, the gain/loss offset values are stored in a testmeasurement offset file on the LMF computer.ManualAgilent E4406A Transmitter Tester – The E4406A does not supportthe power level zeroing calibration performed by the LMF. If thisinstrument is to be used for Bay Level Offset calibration and calibrationis attempted with the LMF Calibrate Test Equipment function, theLMF will return a status window failure message stating that zeroingpower is not supported by the E4406A. Refer to the EquipmentCalibration section of Appendix F for instructions on using theinstrument’s self–alignment (calibration) function prior to performingBay Level Offset calibration.Power Meters – Manual power meter calibration procedures to beperformed prior to automated calibration are included in the EquipmentCalibration section of Appendix F.3

Test Set Calibration68P09258A31–AOct 2003 1X SCt 4812T BTS Optimization/ATP 3-79Calibrating Cables OverviewThe LMF Cable Calibration function is used to measure the path loss (indB) for the TX and RX cables, adapters, directional couplers, andattenuators that make up the cable configurations used for testing. Acommunications system analyzer is used to measure the loss of both theTX test cable and the RX test cable configurations. LMF cablecalibration consists of the following processes:Measure the loss of a short cableThis is done to compensate for any measurement error of thecommunications system analyzer. The short cable, which is used only forthe calibration process, is connected in series with both the TX and RXtest cable configurations when they are measured.The measured loss of the TX and RX test cable configurations minus themeasured loss of the short cable equals the actual loss of theconfigurations. This is done so that any error in the analyzermeasurement is eliminated from both the TX and RX measurements.Measure the loss of the short cable plus the RX testcable configurationThe RX test cable configuration normally consists only of a coax cablewith type–N connectors that is long enough to reach from the BTS RXconnector to the test equipment.When the BTS antenna connectors carry duplexed TX and RX signals, adirectional coupler is required and an additional attenuator may also berequired (for certain BTS types) for the RX test cable configuration.These additional items must be included in the path loss measurement.Measure the loss of the short cable plus the TX testcable configurationThe TX test cable configuration normally consists of two coax cableswith type–N connectors, a directional coupler, a termination load withsufficient rating to dissipate the BTS output power, and an additionalattenuator, if required by the BTS type. The total path loss of the TX testconfiguration must be as required for the BTS (normally 30 or 50 dB).The Motorola Cybertest analyzer differs from other communicationssystem analyzers because the required attenuation/load is built into thetest set. Because of this, the Cybertest TX test configuration consistsonly of the required length coax cable.3
Test Set Calibration 68P09258A31–AOct 20031X SCt 4812T BTS Optimization/ATP3-80Calibrate Test Cabling using Communications System AnalyzerCable Calibration is used to calibrate both TX and RX test cables.Appendix F covers the procedures for manual cable calibration.NOTE LMF cable calibration cannot be accomplished using an HP8921analyzer for 1.7/1.9 GHz. A different analyzer type or the signalgenerator and spectrum analyzer method (Table 3-29 andFigure 3-25) must be used. Cable calibration values must bemanually entered into the LMF cable loss file if the signalgenerator and spectrum analyzer method is used. To use theHP8921A for manual test cable configuration calibration for 800MHz BTSs, refer to the Manual Cable Calibration section ofAppendix F.PrerequisitesSTest equipment is turned on and has warmed up for at least 60minutes. Agilent E7495A requires only 30 minute warmup.STest equipment has been selected in the LMF (Table 3-25 orTable 3-26).STest equipment has been calibrated and correctly connected for thetype of test cable configuration to be calibrated.Calibrating cablesRefer to Figure 3-12, Figure 3-13, or Figure 3-14 and follow theprocedure in Table 3-28 to calibrate the test cable configurations.Table 3-28: Test Cabling Calibration using Comm. System AnalyzernStep Action1 Click Util in the BTS menu bar, and select CableCalibration... in the pull–down menu. A CableCalibration window is displayed.2Enter one or more channel numbers in the Channels boxNOTEMultiple channels numbers must be separated with acomma, no space (i.e., 200,800).

Test Set Calibration68P09258A31–AOct 2003 1X SCt 4812T BTS Optimization/ATP 3-83Setting Cable Loss ValuesCable loss values for TX and RX test cable configurations are normallyset by accomplishing automatic cable calibration using the LMF and theapplicable test equipment. The LMF stores the measured loss values inthe cable loss files. The cable loss values can also be set or changedmanually. Follow the procedure in Table 3-31 to set cable loss values.CAUTION If cable calibration was performed without using the LMF, cableloss values must be manually entered in the LMF database.Failure to do this will result in inaccurate BTS calibration andreduced site performance.PrerequisitesSLMF is logged into the BTSTable 3-31: Setting Cable Loss ValuesStep Action1 Click Util in the BTS menu bar, and select Edit > Cable Loss in the pull–down menus.–A tabbed data entry pop–up window will appear.2Click on the TX Cable Loss tab or the RX Cable Loss tab, as required.3To add a new channel number, perform the following:3a – Click on the Add Row button.3b – Click in the Channel # or Loss (dBm) column, as required.3c – Enter the desired value.4To edit existing values, click in the data box to be changed and change the value.5To delete a row, click on the row and then click on the Delete Row button.6For each tab with changes, click on the Save button to save displayed values.7Click on the Dismiss button to close the window.NOTESValues entered or changed after the Save button was used will be lost when the window isdismissed.SIf cable loss values exist for two different channels the LMF will interpolate for all other channels.SEntered values will be used by the LMF as soon as they are saved.

Bay Level Offset Calibration68P09258A31–AOct 2003 1X SCt 4812T BTS Optimization/ATP 3-85Bay Level Offset CalibrationIntroductionBay Level Offset (BLO) calibration is the central activity of theoptimization process. BLO calibration compensates for normalequipment variations within the BTS RF paths and assures the correcttransmit power is available at the BTS antenna connectors to meet siteperformance requirements.RF Path Bay Level Offset CalibrationCalibration identifies the accumulated gain in every transmit path (BBXslot) at the BTS site and stores that value in a BLO database calibrationtable in the LMF. The BLOs are subsequently downloaded to each BBX.For starter frames, each receive path starts at a BTS RX antenna port andterminates at a backplane BBX slot. Each transmit path starts at a BBXbackplane slot, travels through the Power Amplifier (PA) and terminatesat a BTS TX antenna port.For expansion frames each receive path starts at the BTS RX port of thecell site starter frame, travels through the frame-to-frame expansioncable, and terminates at a backplane BBX slot of the expansion frame.The transmit path starts at a BBX backplane slot of the expansion frame,travels though the PA and terminates at a BTS TX antenna port of thesame expansion frame.Calibration identifies the accumulated gain in every transmit path (BBXslot) at the BTS site and stores that value in a BLO database. Eachtransmit path starts at a C–CCP shelf backplane BBX slot, travelsthrough the PA, and ends at a BTS TX antenna port. When the TX pathcalibration is performed, the RX path BLO is automatically set to thedefault value.At omni sites, BBX slots 1 and 13 (redundant) are tested. At sector sites,BBX slots 1 through 12, and 13 (redundant) are tested. Only those slots(sectors) actually equipped in the current CDF are tested, regardless ofphysical BBX board installation in the slot.When to Calibrate BLOsCalibration of BLOs is required:SAfter initial BTS installationSOnce each yearSAfter replacing any of the following components or associatedinterconnecting RF cabling:– BBX board– C–CCP shelf– CIO card– CIO to Power Amplifier backplane RF cable– PA backplane–PA– TX filter / TX filter combiner– TX thru-port cable to the top of frame3
Bay Level Offset Calibration 68P09258A31–AOct 20031X SCt 4812T BTS Optimization/ATP3-86TX 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.WARNING Before installing any test equipment directly to any TX OUTconnector you must first verify that there are no CDMAchannels keyed. Have the OMC–R place the sector assigned tothe LPA under test OOS. Failure to do so can result in seriouspersonal injury and/or equipment damage.CAUTION Always wear a conductive, high impedance wrist strap whilehandling any circuit card/module. If this is not done, there is ahigh probability that the card/module could be damaged by ESD.NOTE At new site installations, to facilitate the complete test of eachCCP shelf (if the shelf is not already fully populated with BBXboards), move BBX boards from shelves currently not under testand install them into the empty BBX slots of the shelf currentlybeing tested to insure that all BBX TX paths are tested.– This procedure can be bypassed on operational sites that aredue for periodic optimization.– Prior to testing, view the CDF file to verify the correctBBX slots are equipped. Edit the file as required to includeBBX slots not currently equipped (per SystemsEngineering documentation).BLO Calibration Data FileDuring the calibration process, the LMF creates a bts–n.cal calibration(BLO) offset data file in the bts–n folder. After calibration has beencompleted, this offset data must be downloaded to the BBXs using theDownload BLO function. An explanation of the file is shown below.NOTE Due to the size of the file, Motorola recommends that you printout a hard copy of a bts.cal file and refer to it for the followingdescriptions.The 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. Each BBX slotheader 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.3
Bay Level Offset Calibration68P09258A31–AOct 2003 1X SCt 4812T BTS Optimization/ATP 3-87SThe calibration data for a BBX is organized as a large flat array. Thearray is organized by branch, sector, and calibration point.– The first breakdown of the array indicates which branch thecontained calibration points are for.

Twoentries are required for each calibration point.SThe first value (all odd entries) refer to the CDMA channel(frequency) where the BLO is measured. The second value (all evenentries) is the power set level. The valid range for PwrLvlAdj is from2500 to 27500 (2500 corresponds to –125 dBm and 27500corresponds to +125 dBm).SThe 20 calibration entries for each sector/branch combination must bestored in order of increasing frequency. If less than 10 points(frequencies) are calibrated, the largest frequency that is calibrated isrepeated to fill out the 10 points.Example:C[1]=384, odd cal entry= 1 ‘‘calibration point”C[2]=19102, even cal entryC[3]=777,C[4]=19086,..C[19]=777,C[20]=19086, (since only two cal points were calibrated this would be repeated for the next 8 points)SWhen the BBX is loaded with image = data, the cal file data for theBBX is downloaded to the device in the order it is stored in the calfile. TxCal data is sent first, C[1] – C[240]. Sector 1’s ten calibrationpoints are sent (C[1] – C[20]) followed by sector 2’s ten calibrationpoints (C[21] – C[40]), etc. The RxCal data is sent next (C[241] –C[480]), followed by the RxDCal data (C[481] – C[720]).STemperature compensation data is also stored in the cal file for eachset.3
