The corresponding BBX2output level required to achieve that power level on any channel/sectorcan then be determined based on Bay Level Offset (BLO) datadetermined during the optimization process.Refer to the Figure 3-1 and the LMF Help function foradditional information on the layout of the LMF directorystructure (including CDF file locations and formats).NOTEThe CDF is normally obtained from the CBSC on a DOS formatteddiskette, or through a file transfer protocol (ftp), if the LMF computerhas ftp capability. Refer to the LMF Help function, and the LMF Helpfunction, for more information.CDF Site Equipage VerificationIf it has not already been done, review and verify the site equipage datain the CDF with the actual site hardware and the site engineeringdocumentation. Use a text editor to view the CDF contents.Use extreme care not to make any changes to the CDFcontent while viewing the file. Changes to the CDF cancause the site to operate unreliably or render it incapable ofoperation.CAUTIONAlways 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.CAUTIONBTS System Release SoftwareDownloadThe System Release software (for example R2.15.x.x) being used by theBase Station System (BSS) must be successfully downloaded to the BTSprocessor boards before optimization can be performed. Deviceinitialization code is normally downloaded to the processor boards fromthe CBSC. Device application code and data is loaded from the CDMALMF computer terminal.3](https://usermanual.wiki/Nokia-Solutions-and-Networks/T5BR1.IHET5BR1-User-Manual-Part-2-of-3/User-Guide-170603-Page-1.png)
![Preparing the LMFPRELIMINARY1X SCt4812ET Lite BTS Optimization/ATP 08/01/20013-4OverviewBefore optimization can be performed, the CDMA LMF must beinstalled and configured on a computer platform meetingMotorola–specified requirements (see Recommended Test Equipmentand Software in Chapter 1).For the CDMA LMF graphics to display properly, thecomputer platform must be configured to display morethan 256 colors. See the operating system softwareinstructions for verifying and configuring the displaysettings.IMPORTANT*Software and files for installing and updating the CDMA LMF areprovided on CD ROM disks. The following items must be available:SCDMA LMF Program on CD ROMSCDMA LMF Binaries on CD ROMSConfiguration Data File (CDF) for each supported BTS (on floppydisk)SCBSC File for each supported BTS (on floppy disk)The following section provides information and instructions forinstalling and updating CDMA LMF software and files.LMF Installation and Update ProceduresFirst Time Installation Sequence:1.

This requires creatingversions of the CBSC CDF files on a DOS–formatted floppy disketteand using the diskette to install the CDF files on the CDMA LMFcomputer.When copying CDF files, comply with the following toprevent BTS login problems with the Windows LMF:SThe numbers used in the bts-#.cdf andcbsc-#.cdf filenames must correspond to thelocally–assigned numbers for each BTS and itscontrolling CBSC.SThe generic cbsc–1.cdf file supplied with the WindowsLMF will work with locally numbered BTS CDF files.Using this file will not provide a valid optimizationunless the generic file is edited to replace defaultparameters (e.g., channel numbers) with the operationalparameters used locally.IMPORTANT*The procedure in Table 3-2 lists the steps required to transfer the CDFfiles from the CBSC to the CDMA LMF computer. For any furtherinformation, refer to the CDMA LMF Operator’s Guide (Motorola partno. 68P64114A21) or the CDMA LMF Help screen.Table 3-2: Copying CBSC CDF Files to the LMF ComputerStep Action1Login to the CBSC workstation.2Insert a DOS–formatted floppy diskette in the workstation drive.3 Type eject –q and press the Enter key.. . . continued on next page3](https://usermanual.wiki/Nokia-Solutions-and-Networks/T5BR1.IHET5BR1-User-Manual-Part-2-of-3/User-Guide-170603-Page-3.png)

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 theCDMA LMF computer 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–# which must be supported by the CDMA 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.11 If it is not running, start the Windows operating system on the CDMA LMF computer.12 Insert the diskette containing the bts–#.cdf and cbsc–#.cdf files into the CDMA LMF computer.13 Using MS Windows Explorer, create a corresponding bts–# folder in the wlmf\cdma directory for eachbts–#.cdf/cbsc–#.cdf file pair copied from the CBSC.14 Use MS Windows Explorer to transfer the cbsc–#.cdf and bts–#.cdf files from the diskette to thecorresponding wlmf\cdma\bts–# folders created in step 13. 3](https://usermanual.wiki/Nokia-Solutions-and-Networks/T5BR1.IHET5BR1-User-Manual-Part-2-of-3/User-Guide-170603-Page-4.png)

![Span Lines – Interface and IsolationPRELIMINARY1X SCt4812ET Lite BTS Optimization/ATP 08/01/20013-14T1/E1 Span InterfaceAt active sites, the OMC–R/CBSC must disable the BTSand place it out of service (OOS). DO NOT remove thespan line cable conectors until the OMC–R/CBSC hasdisabled the BTS.IMPORTANT*Each frame is equipped with one 50–pair punchblock for spans,customer alarms, remote GPS, and BTS frame alarms. See Figure 3-9and refer to Table 3-5 for the physical location and punchdown locationinformation.Before connecting the LMF computer to the frame LAN, theOMC–R/CBSC must disable the BTS and place it OOS to allow theLMF to control the BTS. This prevents the CBSC from inadvertentlysending control information to the BTS during LMF–based tests.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 cable connector for the BTS–to–CBSCTranscoder span at the Span I/O card (Figure 3-7).If the BTS is a multi–frame logical BTS, do not disconnectthe inter–frame span.IMPORTANT*Figure 3-7: Disconnecting Span Lines Span Line CableConnectors4812ETL0020–13](https://usermanual.wiki/Nokia-Solutions-and-Networks/T5BR1.IHET5BR1-User-Manual-Part-2-of-3/User-Guide-170603-Page-12.png)

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 CDMA LMF in either environment includesperforming 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 CDMA LMFoperations, refer to the LMF Help function and the LMF CLI Reference;68P09253A56.Unless otherwise noted, LMF procedures in this manualare performed using the GUI environment.IMPORTANT*CDMA LMF and Logical BTSAn SC4812ET Lite logical BTS can consist of up to two SC4812ET Liteframes. When the CDMA LMF is connected to a frame 1 Ethernet portof a logical BTS, access is available to all devices in all of the framesthat make up the logical BTS. A logical BTS CDF file that includesequipage information for all of the logical BTS frames and their devicesis required for proper LMF interface. A CBSC CDF file that includeschannel data for all of the logical BTS frames is also required.The first frame of a logical BTS has a –1 suffix (for example,BTS–812–1) and the second frame of the logical BTS is numbered withthe suffix, –101 (e. g. BTS–812–101). When the CDMA LMF is loggedinto a BTS, a FRAME tab is displayed for each frame. If there is onlyone frame for the BTS, there will only be one tab (e.g., FRAME–282–1for BTS–282). If a logical BTS has more than one frame, there will be a3](https://usermanual.wiki/Nokia-Solutions-and-Networks/T5BR1.IHET5BR1-User-Manual-Part-2-of-3/User-Guide-170603-Page-19.png)

If an RFDS isincluded in the CDF file, an RFDS tab (e.g., RFDS–438–1) will bedisplayed.Actions, such as ATP tests, can be initiated for selected devices in one ormore frames of a logical BTS. Refer to the CDMA LMF Select deviceshelp screen for information on how to select devices.Logging Into a BTSBe sure that the correct bts–#.cdf and cbsc–#.cdf file isused for the BTS. These should be the CDF files that areprovided for the BTS by the CBSC. Failure to use thecorrect CDF files can result in invalid optimization.Failure to use the correct CDF files to log into a live(traffic–carrying) site can shut down the site.CAUTIONLogging into a BTS establishes a communications link between the BTSand the CDMA LMF. You may be logged into one or more BTSs at atime, but only one CDMA LMF may be logged into each BTS.Before attempting to start the CDMA LMF computer and the CDMALMF software, confirm the CDMA LMF computer is properly connectedto the BTS (see Table 3-6). Follow the procedures in Table 3-7 to loginto a BTS.PrerequisitesBefore attempting to log into a BTS, ensure the following have beencompleted:SThe CDMA LMF is correctly installed and prepared.SA bts-nnn folder with the correct CDF and CBSC files exists.SThe CDMA LMF computer was connected to the BTS before startingthe Windows operating system and the CDMA LMF software.

Device application (RAM) code and datamust be downloaded to each equipped device by the user before the BTScan be made fully functional for the site where it is installed.ROM CodeDownloading ROM code to BTS devices from the CDMA LMF is NOTroutine maintenance or a normal part of the optimization process. It isonly done in unusual situations where the resident ROM code in thedevice does not match the release level of the site operating softwareAND the CBSC can not communicate with the BTS to perform thedownload. An example would be a BTS loaded with Release 9.2software where a GLI loaded with Release 2.8.1 ROM code must beinstalled to replace a malfunctioning MGLI.Before ROM code can be downloaded from the CDMA LMF, the correctROM code file for each device to be loaded must exist on the LMFcomputer. 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. The same Revision–level RAM code must thenbe downloaded to the device. For example, if Release 2.9.2.1.1 ROMcode is downloaded, Release 2.9.2.1.1 RAM code must be downloaded.Procedures to load ROM code are located in Appendix G.RAM CodeBefore RAM code can be downloaded from the CDMA LMF, the correctRAM code file for each device must exist on the LMF computer. RAMcode can be automatically or manually selected depending on the Devicemenu item chosen and where the RAM code file for the device is storedin the CDMA LMF file structure. The RAM code file will be selectedautomatically if the file is in the \lmf\cdma\loads\n.n.n.n\code folder(where n.n.n.n is the version number of the download code that matchesthe “NextLoad” parameter of the CDF file).

The DOD 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).3NOTESIf equipped with two CSMs, CSM–1 should be bright green (INS–ACT) and CSM–2 should bedark green(INS–STB)SIf more than an hour has passed, refer to CSM Verification, see Figure 3-13 and Table 3-20 todetermine the cause.After the CSMs have been successfully enabled, be sure the PWR/ALM LEDs are steady green(alternating green/red indicates the card is in an alarm state). Enable MCCsThis procedure configures the MCC and sets the “tx fine adjust”parameter. The “tx fine adjust” parameter is not a transmit gain setting,but a timing adjustment that compensates for the processing delay in theBTS (approximately 3 mS).Follow the steps outlined in Table 3-18 to enable the MCCs installed inthe SCCP shelves.The MGLI and CSM must be downloaded and enabled,prior to downloading and enabling the MCC.IMPORTANT*Table 3-18: Enable MCCsStep Action1Click on the target MCC(s) or from the Select pull down menu choose All MCCs.2From the Device menu, select EnableA status report is displayed confirming change in the device(s) status.3 Click OK to close the status report window. 3](https://usermanual.wiki/Nokia-Solutions-and-Networks/T5BR1.IHET5BR1-User-Manual-Part-2-of-3/User-Guide-170603-Page-34.png)
![CSM System Time – GPS & LFR/HSO Verification08/01/2001 3-371X SCt4812ET Lite BTS Optimization/ATPPRELIMINARYClock SynchronizationManager (CSM) System TimeThe primary function of the Clock Synchronization Manager (CSM)cards is to maintain CDMA system time. The CSM card in SCCP shelfslot CSM–1 is the primary timing source while the card in slot CSM–2provides redundancy. The second generation CSM card (CSM2) isrequired when using the remote GPS receiver (R–GPS). R–GPS uses aGPS receiver in the antenna head that has a digital output to the CSM2card. A CSM2 card can have a local GPS receiver daughter card tosupport an RF–GPS signal.Each CSM2 card features a temperature–stablized, crystal oscillator thatprovides 19.6608 MHz clock, even second pulse, and 3 MHz referencesignals to the synchronization source selected from the following (referto Table 3-20 for source selection/verification procedures):SGPS: local/RF–GPS or remote/R–GPSSLORAN–C Low Frequency Receiver (LFR) or High StabilityOscillator (HSO)SExternal reference oscillator sourcesCDMA Clock Distribution Cards (CCDs) buffer and distributeeven–second reference and 19.6608 MHz clock signals from the CSMcards. CCD 1 is married to the card in slot CSM–1, and CCD 2 ismarried to the card in slot CSM–2.The BTS switches between the primary and redundant units (card slotsCSM–1 and CSM–2, respectively) upon failure or command. A failurein CSM–1 or CCD 1 will cause the system to switch to theCSM–2–CCD 2 redundant card pair.Fault management has the capability of switching between the GPSsynchronization source and the LFR/HSO backup source in the event ofa GPS receiver failure in CSM–1. During normal operation, the card inCSM–1 selects GPS as the primary timing source (Table 3-20). Thesource selection can also be overridden via the CDMA LMF or by thesystem software.In addition to providing GPS synchronization to the LFR or HSOback–up sources, synchronization between the primary and redundantCSM–CCD pairs increases reliability.Low Frequency Receiver/High Stability OscillatorThe CSM performs 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–C RFsignals. Timing pulses are derived from this signal, which is3](https://usermanual.wiki/Nokia-Solutions-and-Networks/T5BR1.IHET5BR1-User-Manual-Part-2-of-3/User-Guide-170603-Page-35.png)

TheLFR can maintain system time indefinately after initial GPS lock.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 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 (Table 3-20). HSO,HSO2, and HSOX use the same source code in source selection(Table 3-20).Allow the base site and test equipment to warm up for60 minutes after any interruption in oscillator power. CSMcard warm-up allows the oscillator oven temperature andoscillator frequency to stabilize prior to test. Testequipment warm-up allows the Rubidium standardtimebase to stabilize in frequency before any measurementsare made.NOTE3](https://usermanual.wiki/Nokia-Solutions-and-Networks/T5BR1.IHET5BR1-User-Manual-Part-2-of-3/User-Guide-170603-Page-36.png)

Calibrating Cables – OverviewThe 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. For BTSs with antenna ports carrying duplexed TXand RX, a directional coupler and, if required by BTS type, anadditional attenuator are also used on the RX cable configuration andmust be included in the measurement.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 BLOs are subsequently downloaded toeach BBX2.Each transmit path starts at an SCCP shelf backplane BBX2 slot, travelsthrough the CIO card, trunking module, LPA, trunking module (again),TX filter or TX filter combiner, DRDC or TRDC, and ends at a BTS TXantenna port.Each receive path starts at a BTS RX antenna port, travels through aDRDC or TRDC, the MPC card, the CIO card, and terminates at abackplane BBX2 slot.Calibration identifies the accumulated gain in every transmit path ( byBBX2 slot) at the BTS site and stores that value in the CAL file. Whenthe TX path calibration is performed, the RX path BLO willautomatically be set to the 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.

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 SCCP 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.

After calibration has beencompleted, this offset data must be downloaded to the BBX2s using theCDMA LMF Download BLO function. An explanation of the file isshown below.Due to the size of the file, Motorola recommends printingout a copy of a bts.cal file and referring to it for thefollowing descriptions.NOTEThe CAL file is subdivided into sections organized on a per–slot basis (aslot Block).The Slot 1 Block contains the calibration data for the six BBX2 slots.The Slot 20 Block contains the calibration data for the redundant BBX2(see Table 3-32). Each BBX2 slot Block header 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 – plus the slot Block format.Within the slot Block body, the BBX2 calibration data (BayLevelCal) isorganized as a large flat array. The array is organized by branch, BBX2SCCP cage slot, and calibration point.SThe first breakdown of the array indicates which branch the containedcalibration points are for. The array covers transmit, main receive, anddiversity receive offsets as follows:Table 3-31: BLO BTS.cal file Array Branch AssignmentsRange Branch AssignmentC[1]–C[120] TransmitC[121]–C[240] No SC4812ET Lite BLO calpoint entries (default only)C[241]–C[360] ReceiveC[361]–C[480] No SC4812ET Lite BLO calpoint entries (default only)C[481]–C[600] Diversity ReceiveC[601]–C[720] No SC4812ET Lite BLO calpoint entries (default only)3](https://usermanual.wiki/Nokia-Solutions-and-Networks/T5BR1.IHET5BR1-User-Manual-Part-2-of-3/User-Guide-170603-Page-64.png)

It can be seen thatthere is one BBX2 slot per sector, and 10 calibration points for eachBBX2 (sector) are supported for each branch. Each “calibration point”consists of two entries.SThe first entry for a calibration point (all odd entries) identifies theCDMA channel (frequency) where the BLO is measured. The secondcalibration point entry (all even entries) is the power set level(PwrLvlAdj). The valid range for PwrLvlAdj is from 2500 to 275003](https://usermanual.wiki/Nokia-Solutions-and-Networks/T5BR1.IHET5BR1-User-Manual-Part-2-of-3/User-Guide-170603-Page-65.png)

If less than 10 points(frequencies) are calibrated, the BLO data for the highest frequencycalibrated is written into the remainder of the 10 points for thatslot/branch.Example:C[1]=384 (odd cal entry)C[2]=19102 (even cal entry)C[3]=777 (odd cal entry)C[4]=19086 (even cal entry)C[19]=777 (odd cal entry)C[20]=19086 (even cal entry)...= 1 “calibration point”In the example above, BLO was measured at only two frequencies(channels 384 and 777) for SCCP slot BBX–1 transmit (Table 3-32).The BLO data for the highest frequency measured (777) will bewritten to the remaining eight transmit calibration points (defined byentries C[5] through C[20]) for BBX2–1.SWhen BLO data is downloaded to the BBXs, the data is downloadedto the devices in the order it is stored in the CAL file. TxCal data(C[1] – C[60]) is sent first. BBX2 slot 1’s 10 calibration points (C[1]– C[20]) are sent initially, followed by BBX2 slot 2’s 10 calibrationpoints (C[21] – C[40]), and so on. The RxCal data is sent next,followed by the RxDCal data.STemperature compensation data (TempLevelCal) is also stored in theCAL file for each slot Block.Test Equipment Setup:RF Path CalibrationFollow the steps outlined in Table 3-33 and refer as needed toFigure 3-15 or Figure 3-16 to set up test equipment.Table 3-33: Set Up Test Equipment (RF Path Calibration)Step Action1If it has not already been done, refer to the procedure in Table 3-6 to interface the CDMA LMFcomputer terminal to the frame LAN A connector.2If it has not already been done, refer to Table 3-7 to start a GUI LMF session.3If required, calibrate the test equipment per the procedure in Table 3-25.3](https://usermanual.wiki/Nokia-Solutions-and-Networks/T5BR1.IHET5BR1-User-Manual-Part-2-of-3/User-Guide-170603-Page-66.png)

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 1900MHz.4For TX path calibration, verify that the coaxial cable from the appropriate ANTENNA connector(Figure 1-6 or Figure 1-7) is connected to the test equipment RF input port via the directionalcoupler.Transmit (TX) Path CalibrationThe assigned channel frequency and desired power level at the frame TXports for transmit calibration are derived from the BTS CDF file. EachBBX2 at the site is assigned to a sector and carrier. These are specifiedrespectively in the sector and carrier fields of the ParentCARRIERparameter in each BBX2’s CDF file block. The channel frequency anddesired power for the assigned sector are specified respectively in theChannelList and SIFPilotPwr parameters of the CDF block for theCARRIER to which the BBX2 is assigned.The calibration procedure attempts to adjust the measured power towithin +0.5 dB of the desired power. The calibration will pass if theerror is less than +1.5 dB.The TX BLO for the SC4812ET Lite is approximately 42.0 dB ±5.0 dB.BLO is the gain in dB between the known power output of the BBX2and the measured power at the TX port. BLO is derived by deducting theknown BBX2 power output from the power measured at the TX port or(Measured Power) – (BBX2 TX Power Output).Example:Measured Power (at TX port) = 36.0 dBmKnown BBX TX Power Output = –6.0 dBmBLO = (36.0) – (–6.0) = 42.0 dB gainThe CDMA LMF Tests menu list items TX Calibration and AllCal/Audit perform TX BLO Calibration testing for installed BBX(s).The All Cal/Audit menu item initiates a series of actions to perform TXcalibration, download BLO, and perform TX audit if the TX calibrationpasses. The TX Calibration selection performs only the TX calibration.When the TX Calibration selection is used, BLO download and TXaudit must be performed as separate activities. All measurements aremade through the appropriate antenna connector using the calibrated TXcable setup.In both the TX Calibration and All Cal/Audit dialog boxes, a VerifyBLO checkbox is provided and checked by default. 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.

![RFDS Setup and Calibration – continuedPRELIMINARY1X SCt4812ET Lite BTS Optimization/ATP 08/01/20013-82RFDS CalibrationThe RFDS Calibration option is used to calibrate the RFDS TX and RXpaths. For a TX antenna path calibration the BTS XCVR is keyed at apre–determined power level and the BTS power output level is measuredby the RFDS. The power level is then measured at the TX antennadirectional coupler by the power measuring test equipment item beingused (power meter or analyzer). The difference (offset) between thepower level at the RFDS and the power level at the TX antennadirectional coupler is used as the TX RFDS calibration offset value.For an RX antenna path calibration the RFDS is keyed at apre–determined power level and the power input level is measured by theBTS XCVR. A CDMA signal at the same power level measured by theBTS XCVR is then injected at the RX antenna directional coupler by theCDMA communications analyzer. The difference (offset) between theRFDS keyed power level and power level measured at the BTS XCVR isthe RFDS RX calibration offset value.The TX and RX RFDS calibration offset values are written to the CALfile.For each RFDS TSIC, the channel frequency is determined at the lowerthird and upper third of the appropriate band using the frequencies listedin Table 3-44.Table 3-44: 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 BBXchannels keyed.

![Automated Acceptance Test Procedure – Introduction08/01/2001 4-11X SCt4812ET Lite BTS Optimization/ATPPRELIMINARYIntroductionThe automated Acceptance Test Procedure (ATP) allows Cellular FieldEngineers (CFEs) to run automated acceptance tests on all equipped BTSsubsystem devices using the CDMA LMF GUI environment andsupported test equipment.The operator can choose to save the results of these tests to a report file,from which ATP reports are generated for later printout.Perform the ATP test on out-of-service sectors or sites only. Because alltests are controlled via the CDMA LMF computer using the GPIBinterface from the CDMA LMF computer, only recommended testequipment supported by the CDMA LMF can be used.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*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.NOTEThe CFE selects the appropriate ATP tests to run to satisfy customer andregulatory requirements for verifying cell site performance.

![Prepare to Leave the Site08/01/2001 5-31X SCt4812ET Lite BTS Optimization/ATPPRELIMINARYRemoving External TestEquipment Perform the procedure in Table 5-3 to disconnect the test equipment andconfigure the BTS for active service.Table 5-3: Remove External Test EquipmentStep Action1Disconnect all external test equipment from all TX and RX connectors at the rear of the frame.2Reconnect and visually inspect all TX and RX antenna feed lines at the frame RF interface panel.! CAUTIONVerify that all sector antenna feed lines are connected to the correct ports on the frame. Crossedantenna cables will cause system degradation of call processing.Reset All Devices and InitializeSite RemotelyGenerally, devices in the BTS should not be left with data and codeloaded from the CDMA LMF. The configuration data and code loadsused for normal operation could be different from those stored in theCDMA LMF files. By resetting all devices, the required data and codecan be loaded from the CBSC when spans are again active.To reset all devices and have the OMCR/CBSC bring up the siteremotely, perform the procedure in Table 5-4.Table 5-4: Reset BTS Devices and Remote Site InitializationStep Action1Terminate the CDMA LMF session by following the procedures in Table 5-6.2NOTEIn the following step, performing Table 2-6 DC voltage measurements other than those using the MAPVOLT and AMP indicators is not necessary if DC power system components have not been replacedduring the optimization and/or ATP process.Cycle BTS power off, as specified in Table 2-9, and on, as specified in Table 2-5, Table 2-6, and step 1of Table 2-7, respectively.3Reconnect spans by following the procedure in Table 5-7.4Notify the OMCR/CBSC to take control of the site and download code and data to the BTS.5Verify the CBSC can communicate with the GLIs.
