Optimization Manual: Scope and LayoutMay 2000 1-1SC 4812T CDMA BTS Optimization/ATPScope of This DocumentThis document provides information pertaining to the optimization andaudit tests of Motorola SC 4812T Base Transceiver Subsystem (BTS)equipment frames equipped with trunked high–power Linear PowerAmplifiers (LPAs) and their associated internal and external interfaces.This document assumes the following prerequisites:SThe BTS frames and cabling have been installed per the BTS FrameInstallation Manual – 68P09226A18, which covers the physical “boltdown” of all SC series equipment frames, and the SC 4812T CDMA BTSInstallation Manual –68P64113A87 which covers BTS specific cablingconfigurations.In most applications the same test procedure is used for all equipmentvariations. However, decision break points are provided throughout theprocedure when equipment specific tests are required.As the CDMA Local Maintenance Facility (LMF)capability comes on–line, applicable LMF basedprocedures will be incorporated. Eventually, only theCDMA LMF platform will be supported as therecommended customer method of interfacing with andservicing the SC series BTS equipment.IMPORTANT*We at Motorola Technical Education & Documentation have strived toincorporate into this document the many suggestions and inputs receivedfrom you, the customer, since the inception of the SC product line. Atthe same time, we have tried to insure that the scope of the documenttargets both the novice and expert site technician and engineer withthe information required to successfully perform the task at hand. Ifin some areas, the manual seems to cover the test in too much detail (ornot enough detail) we hope you will keep this in mind.1

Purpose of the OptimizationMay 2000 1-3SC 4812T CDMA BTS Optimization/ATPWhy Optimize?Proper optimization and calibration assures:SAccurate downlink RF power levels are transmitted from the site.SAccurate uplink signal strength determinations are made by the site.What Is Optimization?Optimization compensates for the site-specific cabling and normalequipment variations. Cables that interconnect the BTS and Duplexerassemblies (if used), for example, are cut and installed at the time of theBTS frame installation at the site. Site optimization guarantees that thecombined losses of the new cables and the gain/loss characteristics andbuilt-in tolerances of each BTS frame do not accumulate, causingimproper site operation.Optimization identifies the accumulated loss (or gain) for all receive andtransmit paths at the BTS site, and stores that value in a database.SThe RX path for the starter frame starts at the ancillary equipmentframe RFDS RX directional coupler antenna feedline port, through theancillary equipment frame RFDS RX directional coupler antennafeedline port, through the RX input port on the top of the frame,through the bandpass filter, Combiner Input/Output (CIO) card,Multicoupler Preselector Card (MPC), and additional splitter circuitry,ending at a Code Division Multiple Access (CDMA) ChannelProcessor (C–CCP) backplane Broad Band Transceiver (BBX2) slot inthe C–CCP shelf.SThe RX path for the expansion frame starts at the ancillary equipmentframe RFDS RX directional coupler antenna feedline port, through theancillary equipment frame RFDS RX directional coupler antennafeedline port, through the RX input port on the top of the starterframe, through the bandpass filter and CIO card, out the expansionport at the top of the starter frame, through the expansion cable to theexpansion port on the expansion frame, through the ExpansionMulticoupler Preselector Card (EMPC) and CIO, ending at a BroadBand Transceiver (BBX2) slot in the C–CCP shelf.SThe TX path starts at the BBX2, through the C–CCP backplane slot,travels through the LPA/Combiner TX Filter and ends at the top of theRFDS TX directional coupler antenna feedline port (CDMA), installedon the ancillary equipment frame. If the RFDS option is added, thenthe TX path continues and ends at the top of the RFDS TX directionalcoupler antenna feedline port installed in the ancillary equipmentframe. The TX paths are identical for the starter and expansionframes. . . . continued on next page1
Purpose of the Optimization – continuedSC 4812T CDMA BTS Optimization/ATP May 20001-4These values are factored in by the BTS equipment internally, leavingonly site specific antenna feed line loss and antenna gain characteristicsto be factored in by the CFE when determining site Effective RadiatedPower (ERP) output power requirements.Each C–CCP shelf BBX2 board is optimized to a specific RX and TXantenna port. (One BBX2 board acts in a redundant capacity for BBX2’s1–12, and is optimized to all antenna ports.) A single value is generatedfor each path, thereby eliminating the accumulation of error that wouldoccur from individually measuring and summing the gain and loss ofeach element in the path.When to OptimizeNew InstallationsAfter the initial site installation, it must be prepared for operation. Thispreparation includes verifying hardware installation, initial power–up,download of operating code, and Clock Synchronization Module (CSM)verification.Next, the optimization is performed. Optimization includes performanceverification and calibration of all transmit and receive RF paths, anddownload of accumulated calibration data.After optimization, a series of manual pre–ATP verification tests arecovered that address alarm/redundancy tests.After manual pre–Acceptance Test Procedure (pre–ATP) verificationtests, a series of manual ATP CDMA verification tests are covered usingthe actual equipment set up. An ATP is also required before the site canbe placed in service.Site ExpansionOptimization is also required after expansion of a site.Periodic OptimizationPeriodic optimization of a site may also be required, depending on therequirements of the overall system.Repaired SitesRefer to Appendix C for detailed basic guideline tables anddetailed Optimization/ATP Test Matrix outlining theminimum tests that must be performed anytime a BTSsubassembly or RF cable associated with it is replaced.IMPORTANT*1
Required Test EquipmentMay 2000 1-5SC 4812T CDMA BTS Optimization/ATPPolicyThe LMF is used in conjunction with Motorola recommended testequipment and is part of a “calibrated test set”. To ensure consistent,reliable, and repeatable optimization test results, only recommended testequipment supported by the LMF must be used to optimize the BTSequipment.During manual testing, you can, of course, substitute testequipment with other test equipment models not supportedby the LMF, but those models must meet the sametechnical specifications.NOTEThe customer has the responsibility of accounting for any measurementvariances and/or additional losses/inaccuracies that can be introducedas a result of test equipment substitutions. Before beginningoptimization or troubleshooting, make sure that the test equipmentneeded is on hand and operating properly.Test Equipment CalibrationOptimum system performance and capacity depend on regular equipmentservice, calibration, and characterization prior to BTS optimization.Follow the original equipment manufacturer (OEM) recommendedmaintenance and calibration schedules closely.Test Cable CalibrationEquipment test cables are very important in optimization. Motorolarecommends that the cable calibration be run at every BTS with the testcables attached. This method compensates for test cable insertion losswithin the test equipment itself. No other allowance for test cableinsertion loss needs to be made during the performance of tests.Another method is to account for the loss by entering it into the LMFduring the optimization procedure. This method requires accurate testcable characterization in a shop. The cable should be tagged with thecharacterization information prior to field optimization.Equipment Warm–upAfter arriving at the a site, the test equipment should be plugged in andturned on to allow warm up and stabilization to occur for as long aspossible. The following pieces of test equipment must be warmed–up fora minimum of 60 minutes prior to using for BTS optimization or RadioFrequency Diagnostic Subsystem (RFDS) calibration procedures.SCommunications Test SetSRubidium Time BaseSPower Meter1

Preliminary Operations: OverviewMay 2000 2-1SC 4812T CDMA BTS Optimization/ATPIntroductionThis section first verifies proper frame equipage. This includes verifyingmodule placement, jumper, and dual in–line package (DIP) switchsettings against the site-specific documentation supplied for each BTSapplication. Next, pre-power up and initial power-up procedures arepresented.Cell Site TypesSites are configured as Omni with a maximum of 4 carriers, 3–sectoredwith a maximum of 4 carriers, and 6–sectored with a maximum of 2carriers. Each type has unique characteristics and must be optimizedaccordingly. For more information on the differences in site types, pleaserefer to the BTS/Modem Frame Hardware Installation manual.CDFThe Cell-site Data File (CDF) contains site type and equipage datainformation and passes it directly to the LMF during optimization. Thenumber of modem frames, C–CCP shelves, BBX2 boards,MCC24/MCC8E boards (per cage), and linear power amplifierassignments are some of the equipage data included in the CDF.Be sure that the correct bts–#.cdf and cbsc–#.cdf files areused for the BTS. These should be the CDF files that areprovided for the BTS by the CBSC. Failure to use thecorrect CDF files can cause system errors. Failure to usethe correct CDF files to log into a live (traffic carrying)site can shut down the site.IMPORTANT*Site Equipage VerificationReview the site documentation. Match the site engineering equipage datato the actual boards and modules shipped to the site. Physically inspectand verify the equipment provided for the BTS or Modem frame andancillary equipment frame.Always wear a conductive, high impedance wrist strapwhile handling any circuit card/module to prevent damageby ESD. After removal, the card/module should be placedon a conductive surface or back into the anti–staticshipping bag.CAUTIONInitial Installation ofBoards/ModulesFollow the procedure in Table 2-1 to verify the initial installation ofboards/modules. . . . continued on next page2

Pre–Power–up Tests – continuedMay 2000 2-5SC 4812T CDMA BTS Optimization/ATPDC Power Pre-test (BTS Frame) Before applying any power to the BTS frame, follow the procedure inTable 2-2 while referring to Figure 2-3 and Figure 2-4 for +27 Vsystems or to Figure 2-5 and Figure 2-6 for –48 V systems to verifythere are no shorts in the BTS frame DC distribution system.Table 2-2: DC Power Pre–test (BTS Frame)Step Action1Physically verify that all DC power sources supplying power to the frame are OFF or disabled.2On each frame:SUnseat all circuit boards (except CCD and CIO cards) in the C–CCP shelf and LPA shelves, butleave them in their associated slots.SSet C–CCP shelf breakers to the OFF position by pulling out power distribution breakers (labeledC–CCP 1, 2, 3 on the +27 V BTS C–CCP power distribution panel and labeled POWER1,4,5,2,6,7,3,8,9 on the –48 V C–CCP power distribution panel).SSet LPA breakers to the OFF position by pulling out the LPA breakers (8 breakers, labeled 1A–1Bthrough 4C–4D – located on the C–CCP power distribution panel in the +27 V BTS or on the powerconversion shelf power distribution panel in the –48 V BTS).3Verify that the resistance from the power (+ or –) feed terminals with respect to the ground terminal onthe top of the frame measures > 500 Ω (see Figure 2-3).SIf reading is < 500 Ω, a short may exist somewhere in the DC distribution path supplied by thebreaker. Isolate the problem before proceeding. A reading > 3 MΩ could indicate an open (ormissing) bleeder resistor (installed across the filter capacitors behind the breaker panel).4Set the C–CCP (POWER) breakers to the ON position by pushing them IN one at a time. RepeatStep 3 after turning on each breaker.* IMPORTANT IMPORTANTIf the ohmmeter stays at 0 Ω after inserting any board/module, a short probably exists in thatboard/module. Replace the suspect board/module and repeat the test. If test still fails, isolate theproblem before proceeding.5Insert and lock the DC/DC converter modules for the C–CCP shelf and into their associated slots oneat a time. Repeat Step 3 after inserting each module.SA typical response is that the ohmmeter steadily climbs in resistance as capacitors charge, finallyindicating approximately 500 Ω.! CAUTION!

Optimization/Calibration – IntroductionMay 2000 3-1SC 4812T CDMA BTS Optimization/ATPIntroductionThis section describes procedures for downloading system operatingsoftware, CSM reference verification/optimization, set up and calibrationof the supported test equipment, transmit/receive path verification, andusing the RFDS.Before using the LMF, use an editor to view the”CAVEATS” section in the ”readme.txt” file in the c:\wlmffolder for any applicable information.IMPORTANT*Optimization ProcessAfter a BTS is physically installed and the preliminary operations(power up) have been completed, the LMF is used to calibrate andoptimize the BTS. Motorola recommends that the optimization beaccomplished as follows:1. Download MGLI2–1 with code and data and then enable MGLI2–1.2. Use the status function and verify that all of the installed devices ofthe following types respond with status information: CSM, BBX2,GLI2, and MCC (and TSU if RFDS is installed). If a device isinstalled and powered up but is not responding and is colored gray inthe BTS display, the device is not listed in the CDF file. The CDFfile will have to be corrected before the device can be accessed bythe LMF.3. Download code and data to all devices of the following types:– CSM– BBX2– GLI2 (other than MGLI2–1)– MCC4. Download the RFDS TSIC (if installed).5. Verify the operation of the GPS and HSO signals.6. Enable the following devices (in the order listed):– Secondary CSM– Primary CSM– All MCCs7. Connect the required test equipment for a full optimization.8. Select the test equipment.9. Calibrate the TX and RX test cables if they have not previously beencalibrated using the CDMA LMF that is going to be used for theoptimization/calibration. The cable calibration values can also beentered manually. . . . continued on next page3
Optimization/Calibration – Introduction – continuedSC 4812T CDMA BTS Optimization/ATP May 20003-210. Select all of the BBXs and all of the MCCs and use the fulloptimization function. The full optimization function performs TXcalibration, BLO download, TX audit, all TX tests, and all RX testsfor all selected devices.11. If the TX calibration fails, repeat the full optimization for any failedpaths.12. If the TX calibration fails again, correct the problem that caused thefailure and repeat the full optimization for the failed path.13. If the TX calibration and audit portion of the full optimization passesfor a path but some of the TX or RX tests fail, correct the problemthat caused the failure and run the individual tests as required untilall TX and RX tests have passed for all paths.Cell Site TypesSites are configured as Omni/Omni or Sector/Sector (TX/RX). Each typehas unique characteristics and must be optimized accordingly.For more information on the differences in site types,please refer to the applicable BTS/Modem Frame HardwareInstallation and Functional Hardware Descriptionmanuals.NOTECell Site Data File (CDF)The CDF contains information that defines the BTS and data used todownload files to the devices. A CDF file must be placed in theapplicable BTS folder before the LMF can be used to log into that BTS.CDF files are normally obtained from the CBSC using a floppy disk. Afile transfer protocol (ftp) method can be used if the LMF computer hasthat capability. The CDF includes the following information:SDownload instructions and protocolSSite specific equipage informationSC–CCP shelf allocation plan– BBX2 equipage (based on cell–site type) including redundancy– CSM equipage including redundancy– Multi Channel Card (MCC24 or MCC8E) channel elementallocation plan. This plan indicates how the C–CCP shelf isconfigured, and how the paging, synchronization, traffic, and accesschannel elements (and associated gain values) are assigned amongthe (up to 12) MCC24s or MCC8Es in the shelf.SCSM equipage including redundancy . . . continued on next page3
Optimization/Calibration – Introduction – continuedMay 2000 3-3SC 4812T CDMA BTS Optimization/ATPSEffective Rated Power (ERP) table for all TX channels to antennasrespectively. Motorola System Engineering specifies the ERP of atransmit antenna based on site geography, antenna placement, andgovernment regulations. Working from this ERP requirement, theantenna gain, (dependent on the units of measurement specified) andantenna feed line loss can be combined to determine the requiredpower at the top of the BTS frame. The corresponding BBX2 outputlevel required to achieve that power level on any channel/sector canalso be determined.Refer to the CDMA LMF Operator’s Guide, 68P64114A21,for additional information on the layout of the LMFdirectory structure (including CDF file locations andformats).NOTEBTS System SoftwareDownloadBTS system software must be successfully downloaded to the BTSprocessor boards before optimization can be performed. BTS operatingcode is loaded from the LMF computer terminal.Before using the LMF for optimization/ATP, the correctbts–#.cdf and cbsc–#.cdf files for the BTS must beobtained from the CBSC and put in a bts–# folder in theLMF. Failure to use the correct CDF files can cause wrongresults. Failure to use the correct CDF files to log into alive (traffic carrying) site can shut down the site.IMPORTANT*The CDF is normally obtained from the CBSC on a DOS formatteddiskette, or through a file transfer protocol (ftp) if the LMF computer hasftp capability. Refer to the CDMA LMF Operator’s Guide, or the LMFHelp screen, for the procedure.Site Equipage VerificationIf you have not already done so, use an editor to view the CDF, andreview the site documentation. Verify the site engineering equipage datain the CDF matches the actual site hardware using a CDF conversiontable.Always wear a conductive, high impedance wrist strapwhile handling any circuit card/module to prevent damageby ESD. Extreme care should be taken during the removaland installation of any card/module. After removal, thecard/module should be placed on a conductive surface orback into the anti–static bag in which it was shipped.CAUTION3
Isolate Span Lines/Connect LMFSC 4812T CDMA BTS Optimization/ATP May 20003-4Isolate BTS from T1/E1 SpansAt active sites, the OMC/CBSC must disable the BTS andplace it out of service (OOS). DO NOT remove the 50–pinTELCO cable connected to the BTS frame site I/O boardJ1 connector until the OMC/CBSC has disabled the BTS!IMPORTANT*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. 8 pairsare used to support up to four 4–wire span lines. 17 pairs are connectedto signal ground.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 3-1 and Figure 3-2 as required.Table 3-1: T1/E1 Span IsolationStep Action1From the OMC/CBSC, disable the BTS and place it OOS. Refer to SC OMC–R/CBSC SystemOperator Procedures.– The T1/E1 span 50–pin TELCO cable connected to the BTS frame SPAN I/O board J1 connectorcan be removed from both Span I/O boards, if equipped, to isolate the spans.* IMPORTANTVerify that you remove the SPAN cable, not the “MODEM/TELCO” connector.Figure 3-1: 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)FW00299 . . . continued on next page3

Preparing the LMFSC 4812T CDMA BTS Optimization/ATP May 20003-6OverviewSoftware and files for installation and updating of the LMF are providedon CD ROM disks. The following installation items must be available:SLMF Program on CD ROMSLMF Binaries on CD ROMSConfiguration Data File (CDF) for each supported BTS (on diskette oravailable from the CBSC)SCBSC File for each supported BTS (on diskette or available from theCBSC)The following section provides information and instructions forinstalling and updating the LMF software and files.Graphical User InterfaceOverviewThe LMF uses a graphical user interface (GUI), which works in thefollowing 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.Logical BTSThe BTS software implements the logical BTS capability, also known asvirtual BTS. Previously, all BTS frames co–located at a single site had tobe identified in the network with separate and distinct BTS ID numbers.In the Logical BTS feature, all frames located at a single BTS site areidentified with unique Frame ID numbers (Frame ID Numbers 1, 101,201, 301) under a single (site) BTS ID number. A logical BTS canconsist of up to four SC 4812T frames.When the LMF is connected toframe 1 of a logical BTS, you can access all devices in all of the framesthat make up the logical BTS. A logical BTS requires a CDF file thatincludes equipage information for all of the logical BTS frames and theirdevices and a CBSC file that includes channel data for all of the logicalBTS fames. . . . continued on next page3
Preparing the LMF – continuedMay 2000 3-7SC 4812T CDMA BTS Optimization/ATPLogical BTS NumberingThe first frame of a logical BTS has a –1 suffix (e.g., BTS–812–1).Other frames of the logical BTS are numbered with suffixes, –101, –201,and –301 (e. g. BTS–812–201). When you log into a BTS, a FRAMEtab is displayed for each frame. If there is only one frame for the BTS,there is only one tab (e.g., FRAME–282–1) for BTS–282. If a logicalBTS has more than one frame, there is a separate FRAME tab for eachframe (e.g. FRAME–438–1, FRAME–438–101, and FRAME–438–201for a BTS–438 that has three frames). If an RFDS is included in theCDF file, an RFDS tab (e.g., RFDS–438–1) is displayed. Figure 3-3shows frame configurations available under the Logical BTS feature.This figure also shows the Inter–frame spans between the differentframes at the BTS site.Actions (e.g., ATP tests) can be initiated for selected devices in one ormore frames of a logical BTS. Refer to the Select devices help screen forinformation on how to select devices.C–CCP Shelf Card/Module Device ID NumbersAll cards/modules/boards in the frames at a single site, assigned to asingle BTS number, are also identified with unique Device ID numbersdependent upon the Frame ID number in which they are located.

This requires copying the CBSC CDF files to a DOSformatted diskette, and using the diskette to install the CDF file in theLMF. . . . continued on next page3
Preparing the LMF – continuedSC 4812T CDMA BTS Optimization/ATP May 20003-10Follow the procedure in Table 3-6 to obtain the CDF files from theCBSC and copy the files to a diskette. For any further information, referto the CDMA LMF Operator’s Guide (Motorola part number68P64114A21) or the LMF Help screen..If the LMF has ftp capability, the ftp method can be used tocopy the CDF 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 acopy of the CBSC CDF file so the original CBSC CDF fileis not changed to DOS format.NOTE*When copying CDF files, comply with the following toprevent BTS login problems with the LMF:– The numbers used in the bts–#.cdf and cbsc–#.cdffilenames must correspond to the locally assigned numbersfor each BTS and its controlling CBSC.– The generic cbsc–1.cdf file supplied with the LMF workwith locally numbered BTS CDF files. Using this file doesnot provide a valid optimization unless the generic file isedited to replace default parameters (e.g., channel numbers)with the operational parameters used locally.IMPORTANTTable 3-6: Copying CBSC CDF Files to the LMFnStep ActionAT THE CBSC:1Login to the CBSC workstation.2Insert a DOS formatted 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.. . . continued on next page3

In these cases,use the Unix cp (copy) command. The copied files will be difficult to read with a DOS orWindows text editor because Unix files do not contain line feed characters. Editing copied CDFfiles on the 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/na_name)8Repeat steps 5 through 7 for each bts–# that must be supported by the LMF.9When all required files have been copied to the diskette, type eject and press the <Enter> key.10 Remove the diskette from the CBSC.AT THE LMF:11 Start the Windows operating system.12 Insert the diskette into the LMF.13 Using Windows Explorer (or equivalent program), create a corresponding bts–# folder in thewlmf\cdma directory for each bts–#.cdf/cbsc–#.cdf file pair copied from the CBSC.14 Use Windows Explorer (or equivalent program) to transfer the cbsc–#.cdf and bts–#.cdf files fromthe diskette to the corresponding wlmf\cdma\bts–# folders created in step 13. Creating a NamedHyperTerminal Connection forMMI ConnectionConfirming or changing the configuration data of certain BTS FieldReplaceable Units (FRUs) requires establishing an MMI communicationsession between the LMF and the FRU. Using features of the Windowsoperating system, the connection properties for an MMI session can besaved on the LMF computer as a named Windows HyperTerminalconnection. This eliminates the need for setting up connectionparameters each time an MMI session is required to supportoptimization. . . . continued on next page3

Download the BTSMay 2000 3-21SC 4812T CDMA BTS Optimization/ATPDownload the BTS – OverviewBefore a BTS can operate, each equipped device must contain deviceinitialization (ROM) code. ROM code is loaded in all devices duringmanufacture or factory repair. 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 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 (e.g.,Release 8.x ROM code and Release 9.x software) AND the CBSC cannotcommunicate with the BTS to perform the download. If you mustdownload ROM code, refer to Appendix H.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.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 is 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). The RAMcode file in the code folder must have the correct hardware bin number.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 devicechanges to OOS-RAM (yellow). When code is downloaded to an MGLI,the LMF automatically also downloads data, and then enables the MGLI.When enabled, the MGLI changes to INS (green).For non–MGLI devices, data must be downloaded after RAM code isdownloaded. To download data, the device state must be OOS–RAM(yellow).3

Enable CSMsEach BTS CSM system features two CSM boards per site. In a typicaloperation, the primary CSM locks its Digital Phase Locked Loop(DPLL) circuits to GPS signals. These signals are generated by either anon–board GPS module (RF–GPS) or a remote GPS receiver (R–GPS).The CSM2 card is required when using the R–GPS. The GPS receiver(mounted on CSM 1) is the primary timing reference and synchronizesthe entire cellular system. CSM 2 provides redundancy but does not havea GPS receiver.The BTS may be equipped with a remote GPS, LORAN–C LowFrequency Receiver (LFR), or HSO 10 MHz Rubidium source, whichthe CSM can use as a secondary timing reference. In all cases, the CSMmonitors and determines what reference to use at a given time.– CSMs are code loaded at the factory. This data isretained in EEPROM.

If Waiting For Phase Lock is shown inthe Description field, the CSM changes to the enabled state after phase lock is achieved. CSM 1houses the GPS receiver. The enable sequence can take up to one hour to complete.* IMPORTANTThe 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 an installed GPS receiver has not been updated for a number of weeks, it may take up to onehour for the GPS 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.)3NOTEIf equipped with two CSMs, the LMF should display CSM-1 as bright GREEN (INS–ACT) andCSM-2 as dark green (INS–STB). After the CSMs have been successfully enabled, thePWR/ALM LEDs are steady green (alternating green/red indicates the card is in an alarm state).If more than an hour has passed, refer to Table 3-18 and Table 3-19 to determine the cause.3

CSM System Time/GPS and LFR/HSO VerificationSC 4812T CDMA BTS Optimization/ATP May 20003-28CSM & 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 MHzsignals are also routed to the RDM EXP 1A & 1B connectors on the topinterconnect panel for distribution to co–located frames 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 3-18). The sourceselection can also be overridden via the LMF or by the system software.All boards are mounted in the C–CCP shelf at the top of the BTS frame.Figure 3-9 on page 3-31 illustrates the location of the boards in the BTSframe. The diagram also shows the CSM front panel.3
CSM System Time/GPS and LFR/HSO Verification – continuedMay 2000 3-29SC 4812T CDMA BTS Optimization/ATPLow Frequency Receiver/High Stability OscillatorThe CSM handles the overall configuration and status monitoringfunctions of the LFR/HSO. In the event of GPS failure, the LFR/HSO iscapable of maintaining synchronization initially established by the GPSreference signal.The LFR requires an active external antenna to receive LORAN RFsignals. Timing pulses are derived from this signal, which issynchronized to Universal Time Coordinates (UTC) and GPS time. TheLFR can maintain system time indefinitely 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 (see Table 3-17).HSO, HSO2, and HSOX use the same source code in source selection(see Table 3-17).Allow the base site and test equipment to warm up for60 minutes after any interruption in oscillator power. CSMboard 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.NOTEFront 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.

Test Set CalibrationMay 2000 3-49SC 4812T CDMA BTS Optimization/ATPTest Set CalibrationBackgroundProper test equipment calibration 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*Purpose of Test setCalibrationThese procedures access the LMF automated calibration routine used todetermine the path losses of the supported communications analyzer,power meter, associated test cables, and (if used) antenna switch thatmake up the overall calibrated test set. After calibration, the gain/lossoffset values are stored in a test measurement offset file on the LMF.3

A CDMA analyzer is used tomeasure the loss of each cable configuration (TX cable configuration andRX cable configuration). The cable calibration consists of the following:SMeasuring the loss of a short cable – This is required to compensatefor any measurement error of the analyzer. The short cable (used onlyfor the calibration process) is used in series with both the TX and RXcable configuration when measuring. The measured loss of the shortcable is deducted from the measured loss of the TX and RX cableconfiguration to determine the actual loss of the TX and RX cableconfigurations. The result is then adjusted out of both the TX and RXmeasurements to compensate for the measured loss.SThe short cable plus the RX cable configuration loss is measured –The RX cable configuration normally consists only of a coax cablewith type-N connectors that is long enough to reach from the BTS RXport of the test equipment. . . . continued on next page3

Bay Level Offset CalibrationMay 2000 3-59SC 4812T CDMA BTS Optimization/ATPIntroduction to Bay LevelOffset CalibrationCalibration compensates for normal equipment variations within theBTS and assures maximum measurement accuracy.RF Path Bay Level OffsetCalibrationCalibration identifies the accumulated gain in every transmit path(BBX2 slot) at the BTS site and stores that value in a BLO databasecalibration table in the LMF. The BLOs are subsequently downloaded toeach BBX2.For starter frames, each receive path starts at a BTS RX antenna port andterminates at a backplane BBX2 slot. Each transmit path starts at aBBX2 backplane slot, travels through the LPA, and terminates at a BTSTX 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 BBX2 slot of the expansion frame.The transmit path starts at a BBX2 backplane slot of the expansionframe, travels though the LPA, and terminates at a BTS TX antenna portof the same expansion frame.Calibration identifies the accumulated gain in every transmit path(BBX2 slot) at the BTS site and stores that value in a BLO database.Each transmit path starts at a C–CCP shelf backplane BBX2 slot, travelsthrough the LPA, and ends at a BTS TX antenna port. When the TX pathcalibration is performed, the RX path BLO is automatically set to thedefault value.At omni sites, BBX2 slots 1 and 13 (redundant) are tested. At sectorsites, BBX2 slots 1 through 12, and 13 (redundant) are tested. Onlythose slots (sectors) actually equipped in the current CDF are tested,regardless of physical BBX2 board installation in the slot.When to Calibrate BLOs Calibration of BLOs is required:SAfter initial BTS installationSOnce each yearSAfter replacing any of the following components or associatedinterconnecting RF cabling:– BBX2 board– C–CCP shelf– CIO card– CIO to LPA backplane RF cable– LPA backplane . . . continued on next page3

The proper functionof each RF path is verified during calibration. The external testequipment is used to validate/calibrate the TX paths of the BTS.Before installing any test equipment directly to any TXOUT connector you must first verify that there are noCDMA channels keyed. Have the OMC–R place the sectorassigned to the LPA under test OOS. Failure to do so canresult in serious personal injury and/or equipment damage.WARNINGAlways wear a conductive, high impedance wrist strapwhile handling any circuit card/module. If this is not done,there is a high probability that the card/module could bedamaged by ESD.CAUTIONAt new site installations, to facilitate the complete test ofeach CCP shelf (if the shelf is not already fully populatedwith BBX2 boards), move BBX2 boards from shelvescurrently not under test and install them into the emptyBBX2 slots of the shelf currently being tested to insure thatall BBX2 TX paths are tested.– This procedure can be bypassed on operational sitesthat are due for periodic optimization.– Prior to testing, view the CDF file to verify thecorrect BBX2 slots are equipped. Edit the file asrequired to include BBX2 slots not currentlyequipped (per Systems Engineering documentation).IMPORTANT*3
Bay Level Offset Calibration – continuedMay 2000 3-61SC 4812T CDMA BTS Optimization/ATPBLO 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 BBX2s using theDownload BLO function. An explanation of the file is shown below.Due to the size of the file, Motorola recommends that youprint out a hard copy of a bts.cal file and refer to it for thefollowing descriptions.NOTEThe CAL file is subdivided into sections organized on a per slot basis (aslot Block).Slot 1 contains the calibration data for the 12 BBX2 slots. Slot 20contains the calibration data for the redundant BBX2. Each BBX2 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.SThe calibration data for a BBX2 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.

Bay Level Offset Calibration – continuedSC 4812T CDMA BTS Optimization/ATP May 20003-64TX Path CalibrationThe assigned channel frequency and power level (as measured at the topof the frame) for transmit calibration are derived from the site CDF files.For each BBX2, 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 BBX2 (locatedunder the ParentSECTOR field of the ParentCARRIER CDF fileparameter).If both the BTS–x.cdf and CBSC–x.cdf files are current,all information will be correct on the LMF. If not, thecarrier and channel will have to be set for each test.NOTEThe 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 BBX2 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 BBX2 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).

RFDS Setup and Calibration – continuedSC 4812T CDMA BTS Optimization/ATP May 20003-78RFDS CalibrationThe RFDS TX and RX antenna paths must be calibrated to ensure peakperformance. The RFDS calibration option calibrates the RFDS TX andRX paths.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 theRFDS keyed power level and the power level measured at the BTSXCVR is the RFDS RX calibration offset value.The TX and RX RFDS calibration offset values are written to the CALfile.PrerequisitesEnsure the following prerequisites have been met before proceeding:SBBX2s are is INS_TESTSCable calibration has been performedSTX calibration has been performed and BLO has bee downloaded forthe BTSSTest equipment has been connected correctly for a TX calibrationSTest equipment has been selected and calibratedFollow the procedure in Table 3-43 to calibrate the TX and RX antennapaths.Table 3-43: RFDS Calibration ProcedurenStep Action1Select the RFDS tab.2 Select RFDS menu.3 Select RFDS Calibration menu item.4Select the appropriate direction (TX or RX) in the Direction pick list.5Type the appropriate channel number(s) in the Channel box.NOTESeparate channel numbers with a comma or dash (no spaces) if using more than one channelnumber (e.g., 247,585,742 or 385–395 for numbers through and including).3

BTS Alarms TestingSC 4812T CDMA BTS Optimization/ATP May 20003-80Alarm Test OverviewALARM connectors provide Customer Defined Alarm Inputs andOutputs. The customer can connect BTS site alarm input sensors andoutput devices to the BTS, thus providing alarm reporting of activesensors as well controlling output devices.The SC 4812T is capable of concurrently monitoring 36 input signalscoming into the BTS. These inputs are divided between 2 Alarmconnectors marked ‘ALARM A’ and ‘ALARM B’ located at the top ofthe frame (see Figure 3-19). The ALARM A connector is alwaysfunctional; ALARM B is functional when an AMR module is equippedin the AMR 2 slot in the distribution shelf. ALARM A port monitorsinput numbers 1 through 18, while ALARM B port monitors inputnumbers 19 through 36 (see Figure 3-20). State transitions on these inputlines are reported to the LMF and OMCR as MGLI Input Relay alarms.ALARM A and ALARM B connectors each provide 18 inputs and 8outputs. If both A and B are functional, 36 inputs and 16 outputs areavailable. They may be configured as redundant. The configuration is setby the CBSC.Alarm Reporting DisplayThe Alarm Monitor window can be displayed to list alarms that occurafter the window is displayed. To access the Alarm Monitor window,select Util>Alarm Monitor.The following buttons are included:SThe Options button allows for a severity level (Warning, Minor, andMajor) selection. The default is all levels. To change the level ofalarms reported click on the Options button and highlight the desiredalarm level(s). To select multiple levels press the <Ctrl> key (forindividual selections) or <Shift> key (for a range of selections) whileclicking on the desired levels.SThe Pause button pauses/stops the display of alarms. When the Pausebutton is clicked the name of the button changes to Continue. Whenthe Continue button is clicked, the display of alarms continues.Alarms that occur between the time the Pause button is clicked andthe Continue button is clicked are not displayed.SThe Clear button clears the Alarm Monitor display. New alarms thatoccur after the Clear button is clicked are displayed.SThe Dismiss button dismisses/closes the Alarm Monitor display.3

Automated Acceptance Test Procedures – All–inclusive TX & RXMay 2000 4-1SC 4812T CDMA BTS Optimization/ATPIntroductionThe Automated Acceptance Test Procedure (ATP) allows Cellular FieldEngineers (CFEs) to run automated acceptance tests on all equipped BTSsubsystem devices using the Local Maintenance Facility (LMF) andsupported 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 from the LMF platformusing the GPIB interface, therefore, only recommended test equipmentsupported by the LMF can be used.Before performing any tests, use an editor to view the“CAVEATS” section of the “readme.txt” file in the c:\wlmffolder for any applicable information.The ATP test is to be performed on out-of-service (OOS)sectors only.DO NOT substitute test equipment not supported by theLMF.IMPORTANT*Refer to Chapter 3 for detailed information on test setconnections for calibrating equipment, cables and other testset components, if required.NOTECustomer requirements determine which ATP tests to are to beperformed and the craftsperson selects the appropriate ATP tests to run.The tests can be run individually or as one of the following groups:SAll TX: TX tests verify the performance of the BTS transmit line up.These include the GLI, MCC, BBX2, and CIO cards, the LPAs andpassive components including splitters, combiners, bandpass filter,and RF cables.SAll RX: RX tests verify the performance of the BTS receiver line up.These includes the MPC (for starter frames), EMPC (for expansionframes), CIO, BBX2, MCC, and GLI cards and the passivecomponents including RX filter (starter frame only), and RF cables.SAll TX/RX: Executes all the TX and RX tests.SFull Optimization: Executes the TX calibration, downloads the BLO,and executes the TX audit before running all of the TX and RX tests.4
Automated Acceptance Test Procedure – All–inclusive TX & RX – continuedSC 4812T CDMA BTS Optimization/ATP May 20004-2ATP Test PrerequisitesBefore attempting to run any ATP tests, ensure the following have beencompleted:SBTS has been optimized and calibrated (see Chapter 3).SLMF is logged into the BTS.SCSMs, GLIs, BBX2s, MCCs, and TSU (if the RFDS is installed) havecorrect code load and data load.SPrimary CSM, GLI, and MCCs are INS_ACT.SBBX2s are calibrated and BLOs are downloaded.SBBX2s are OOS_RAM.STest cables are calibrated.STest equipment is connected for ATP tests (see Figure 3-13 throughFigure 3-16 starting on page 3-45).STest equipment has been warmed up 60 minutes and calibrated.SGPIB is on.Before the FER is run, be sure that all LPAs are turnedOFF (circuit breakers pulled) or that all transmitter portsare properly terminated.All transmit ports must be properly terminated for all ATPtests.Failure to observe these warnings may result in bodilyinjury or equipment damage.WARNINGTX OUT ConnectionMany of the acceptance test procedures require takingmeasurements at the TX OUT (BTS/RFDS) connector. Atsites without RFDS installed, all measurements will be viathe BTS TX OUT connector. At sites with RFDS installed,all measurements will be via the RFDS directional couplerTX OUT connector.IMPORTANT*4

TX Output Acceptance Tests: IntroductionMay 2000 4-5SC 4812T CDMA BTS Optimization/ATPIndividual Acceptance TestsThe following individual ATP tests can be used to verify the results ofspecific tests.Spectral Purity TX Mask (Primary & Redundant BBX2)This test verifies that the transmitted CDMA carrier waveform generatedon each sector meets the transmit spectral mask specification withrespect to the assigned CDF file values.Waveform Quality (rho)This test verifies that the transmitted Pilot channel element digitalwaveform quality (rho) exceeds the minimum specified value inANSI–J_STD–019. “Rho” represents the correlation between actual andperfect CDMA modulation spectrum. A rho value of 1.0000 represents100% (or perfect correlation).Pilot Time OffsetThe Pilot Time Offset is the difference between the CDMA analyzermeasurement interval (based on the BTS system time reference) and theincoming block of transmitted data from the BTS (Pilot only, PilotGain = 262, PN Offset = 0).Code Domain Power (Primary & Redundant BBX2)This test verifies the code domain power levels, which have been set forall ODD numbered Walsh channels, using the OCNS command. This isdone by verifying that the ratio of PILOT divided by OCNS is equal to10.2 + 2 dB, and, that the noise floor of all EVEN numbered “OFF”Walsh channels measures < –27 dB (with respect to total CDMA channelpower).Frame Error RateThe Frame Error Rate (FER) test verifies RX operation of the entireCDMA Reverse Link using all equipped MCCs assigned to allrespective sector/antennas. This test verifies the BTS sensitivity on alltraffic channel elements currently configured on all equipped MCCs atan RF input level of –122 dBm (or –116 dBm if using TMPC).4
TX Spectral Purity Transmit Mask Acceptance TestSC 4812T CDMA BTS Optimization/ATP May 20004-6Tx Mask TestThis test verifies the spectral purity of each BBX carrier keyed up at aspecific frequency, per the current CDF file assignment. All tests areperformed using the external calibrated test set, controlled by the samecommand. All measurements are via the appropriate TX OUT(BTS/RFDS) connector.The Pilot Gain is set to 541 for each antenna and all channel elementsfrom the MCCs are forward-link disabled. The BBX is keyed up, usingboth bbxlvl and bay level offsets, to generate a CDMA carrier (with pilotchannel element only). BBX power output is set to obtain +40 dBm asmeasured at the TX OUT connector (on either the BTS or RFDSdirectional coupler).TX output power is set to +40 dBm by setting BTS powerlevel to +33.5 dBm to compensate for 6.5 dB increase frompilot gain set to 541.NOTEThe calibrated communications test set measures and returns theattenuation level of all spurious and IM products in a 30 kHz resolutionbandwidth. With respect to the mean power of the CDMA channelmeasured in a 1.23 MHz bandwidth in dB, verify that results meetsystem tolerances at the following test points:S1.7/1.9 GHz:– at least –45 dB @ + 900 kHz from center frequency– at least –45 dB @ – 900 kHz from center frequencyS800 MHz:– at least –45 dB @ + 750 kHz from center frequencY– at least –45 dB @ – 750 kHz from center frequency– at least –60 dB @ – 1980 kHz from center frequency– at least –60 dB @ – 1980 kHz from center frequencyThe BBX2 then de-keys, and, if selected, the MCC is re-configured toassign the applicable redundant BBX2 to the current TX antenna pathunder test. The test is then repeated.4

TX Waveform Quality (rho) Acceptance TestSC 4812T CDMA BTS Optimization/ATP May 20004-8Rho TestThis test verifies the transmitted Pilot channel element digital waveformquality of each BBX carrier keyed up at a specific frequency per thecurrent CDF file assignment. All tests are performed using the externalcalibrated test set controlled by the same command. All measurementsare via the appropriate TX OUT (BTS/RFDS) connector.The Pilot Gain is set to 262 for each antenna, and all channel elementsfrom the MCCs are forward link disabled. The BBX2 is keyed up usingboth bbxlvl and bay level offsets, to generate a CDMA carrier (with pilotchannel element only, Walsh code 0). BBX2 power output is set to 40dBm as measured at the TX OUT connector (on either the BTS orRFDS directional coupler).The calibrated communications test set measures and returns the Pilotchannel element digital waveform quality (rho) in dB, verifying thatresult meets system tolerances:SWaveform quality (rho) should be > 0.912 (–0.4 dB).The BBX then de-keys and, if selected, the MCC is re-configured toassign the applicable redundant BBX2 to the current TX antenna pathunder test. The test is then be repeated.4
TX Pilot Time Offset Acceptance TestMay 2000 4-9SC 4812T CDMA BTS Optimization/ATPPilot Offset Acceptance TestThis test verifies the transmitted Pilot channel element Pilot Time Offsetof each BBX carrier keyed up at a specific frequency per the currentCDF file assignment. All tests are performed using the externalcalibrated test set controlled by the same command. All measurementsare via the appropriate TX OUT (BTS/RFDS) connector.The Pilot Gain is set to 262 for each antenna and all TCH elements fromthe MCCs are forward link disabled. The BBX is keyed up using bothbbxlvl and bay level offsets, to generate a CDMA carrier (with pilotchannel element only, Walsh code 0). BBX power output is set to 40dBm as measured at the TX OUT connector (on either the BTS orRFDS directional coupler).The calibrated communications test set measures and returns the PilotTime Offset in us, verifying results meet system tolerances:SPilot Time Offset should be within < 3 µs of the target PTOffset (0 ms).The BBX then de-keys, and if selected, the MCC is re-configured toassign the applicable redundant BBX to the current TX antenna pathunder test. The test is then repeated.
TX Code Domain Power Acceptance TestSC 4812T CDMA BTS Optimization/ATP May 20004-10Code Domain Power TestThis test verifies the Code Domain Power/Noise of each BBX2 carrierkeyed up at a specific frequency per the current CDF file assignment.All tests are performed using the external calibrated test set controlled bythe same command. All measurements are via the appropriate TX OUT(BTS/RFDS) connector.For each sector/antenna under test, the Pilot Gain is set to 262 and allMCC channel elements under test are configured to generate OrthogonalChannel Noise Source (OCNS) on different odd Walsh codes, and beassigned a full–rate gain of 81. The maximum number of MCC/CEs tobe tested an any one time is 32 (32 odd Walsh codes). If more than 32CEs exist, then multiple sets of measurements are made, so all channelelements are verified on all sectors.BBX2 power output is set to 40 dBm as measured at the TX OUTconnector (on either the BTS or RFDS directional coupler).You verify the code domain power levels, which have been set for allODD numbered Walsh channels, using the OCNS command. This isdone by verifying that Pilot Power (dBm) minus OCNS Power (dBm) isequal to 10.2 + 2 dB and that the noise floor of all “OFF” Walsh channelsmeasures < –27 dB (with respect to total CDMA channel power).The BBX2 then de-keys and, if selected, the MCC is re-configured toassign the applicable redundant BBX2 to the current TX antenna pathunder test. The test is then repeated. Upon completion of the test, OCNSis disabled on the specified MCC/CE.4

RX Frame Error Rate (FER) Acceptance TestSC 4812T CDMA BTS Optimization/ATP May 20004-12FER TestThis test verifies the BTS FER on all traffic channel elements currentlyconfigured on all equipped MCCs (full rate at 1% FER) at an RF inputlevel of –122 dBm [or –116 dBm if using Tower Top Amplifier(TMPC)]. All tests are performed using the external calibrated test set asthe signal source controlled by the same command. All measurementsare via the LMF.The pilot gain is set to 262 for each TX antenna and all channel elementsfrom the MCCs are forward-link disabled. The BBX2 is keyed up usingonly bbxlvl level offsets, to generate a CDMA carrier (with pilot channelelement only). BBX2 power output is set to –20 dBm as measured at theTX OUT connector (on either the BTS or RFDS directional coupler).BBX2 must be keyed in order to enable the RX receive circuitry.The LMF prompts the MCC/CE under test to measure all zero longcodeand provide the FER report on the selected active MCC on the reverselink for both the main and diversity RX antenna paths, verifying thatresults meet the following specification:SFER returned less than 1% and total frames measured is 1500All MCC/CEs selected are tested on the specified RX antenna path. TheBBX then de-keys and, if selected, the MCC is re-configured to assignthe applicable redundant BBX to the current RX antenna paths undertest. The test is then repeated.4

Troubleshooting: CSM ChecklistMay 2000 6-11SC 4812T CDMA BTS Optimization/ATPProblem DescriptionMany of the Clock Synchronization Manager (CSM) boards may beresolved in the field before sending the boards to the factory for repair.This section describes known CSM problems identified in field returns,some of which are field-repairable. Check these problems beforereturning suspect CSM boards.Intermittent 19.6608 MHzReference Clock / GPSReceiver Operation If having any problems with CSM board kit numbers, SGLN1145 orSGLN4132, check the suffix with the kit number. If the kit has version“AB,” then replace with version ‘‘BC’’ or higher, and return model ABto the repair center.No GPS Reference SourceCheck the CSM boards for proper hardware configuration. CSM kitSGLN1145, in Slot l, has an on-board GPS receiver; while kitSGLN4132, in Slot 2, does not have a GPS receiver. Any incorrectlyconfigured board must be returned to the repair center. Do not attempt tochange hardware configuration in the field. Also, verify the GPSantenna is not damaged and is installed per recommended guidelines.Checksum Failure The CSM could have corrupted data in its firmware resulting in anon-executable code. The problem is usually caused by either electricaldisturbance, or interruption of data during a download. Attempt anotherdownload with no interruptions in the data transfer. Return CSM boardback to repair center if the attempt to reload fails.GPS Bad RX Message TypeThis is believed to be caused by a later version of CSM software (3.5 orhigher) being downloaded, via LMF, followed by an earlier version ofCSM software (3.4 or lower), being downloaded from the CBSC.Download again with CSM software code 3.5 or higher. Return CSMboard back to repair center if attempt to reload fails.CSM Reference SourceConfiguration Error This is caused by incorrect reference source configuration performed inthe field by software download.

C–CCP Backplane TroubleshootingMay 2000 6-13SC 4812T CDMA BTS Optimization/ATPIntroductionThe C–CCP backplane is a multi–layer board that interconnects all theC–CCP modules. The complexity of this board lends itself to possibleimproper diagnoses when problems occur.Connector FunctionalityThe following connector overview describes the major types ofbackplane connectors along with the functionality of each. This willallow the CFE to:SDetermine which connector(s) is associated with a specific problemtype.SAllow the isolation of problems to a specific cable or connector.Primary “A” and Redundant “B” Inter Shelf Bus (ISB)ConnectorsThe 40 pin ISB connectors provide an interface bus from the masterGLI2 to all other GLI2s in the modem frame. Their basic function is toprovide clock synchronization from the master GLI2 to all other GLI2sin the frame.The ISB also provides the following functions:SSpan line grooming when a single span is used for multiple cages.SMMI connection to/from the master GLI2 to cell site modem.SInterface between GLI2s and the AMR (for reporting BTS alarms).Span Line ConnectorThe span line input is an 8 pin RJ–45 connector that provides a primaryand secondary (if used) span line interface to each GLI2 in the C–CCPshelf. The span line is used for MM/EMX switch control of the MasterGLI2 and also all the BBX2 traffic.Primary “A” and Redundant “B” Reference DistributionModule (RDM) Input/OutputThese connectors route the 3 MHz reference signals from the CSMs tothe GLI2s and all BBX2s in the backplane. The signals are used to phaselock loop all clock circuits on the GLI2s and BBX2 boards to produceprecise clock and signal frequencies.Power Input (Return A, B, and C connectors)Provides a +27 volt or –48 volt input for use by the power supplymodules.6
C–CCP Backplane Troubleshooting – continuedSC 4812T CDMA BTS Optimization/ATP May 20006-14Power Supply Module InterfaceEach power supply module has a series of three different connectors toprovide the needed inputs/outputs to the C–CCP backplane. Theseinclude a VCC/Ground input connector, a Harting style multiple pininterface, and a +15 V/Analog Ground output connector. The C–CCPPower Modules convert +27 or –48 Volts to a regulated +15, +6.5, and+5.0 Volts to be used by the C–CCP shelf cards. In the –48 V BTS, theLPA power modules convert –48 Volts to a regulated +27 Volts.GLI2 ConnectorThis connector consists of a Harting 4SU digital connector and a6–conductor coaxial connector for RDM distribution. The connectorsprovide inputs/outputs for the GLI2s in the C–CCP backplane.GLI2 Ethernet “A” and “B” ConnectionsThese BNC connectors are located on the C–CCP backplane and routedto the GLI2 board. This interface provides all the control and datacommunications between the master GLI2 and the other GLI2, betweengateways, and for the LMF on the LAN.BBX2 ConnectorEach BBX2 connector consists of a Harting 2SU/1SU digital connectorand two 6–conductor coaxial connectors. These connectors provide DC,digital, and RF inputs/outputs for the BBX2s in the C–CCP backplane.CIO ConnectorsSRX RF antenna path signal inputs are routed through RX Tri–Filters(on the I/O plate), and via coaxial cables to the two MPC modules –the six “A” (main) signals go to one MPC; the six “B” (diversity) tothe other. The MPC outputs the low–noise–amplified signals via theC–CCP backplane to the CIO where the signals are split and sent tothe appropriate BBX2.SA digital bus then routes the baseband signal through the BBX2, tothe backplane, then on to the MCC24 slots.SDigital TX antenna path signals originate at the MCC24s. Eachoutput is routed from the MCC24 slot via the backplane appropriateBBX2.STX RF path signal originates from the BBX2, through the backplaneto the CIO, through the CIO, and via multi-conductor coaxial cablingto the LPAs in the LPA shelf.C–CCP BackplaneTroubleshooting ProcedureTable 6-15 through Table 6-24 provide procedures for troubleshootingproblems that appear to be related to a defective C–CCP backplane.

Module Front Panel LED Indicators and ConnectorsSC 4812T CDMA BTS Optimization/ATP May 20006-20Module Status IndicatorsEach of the non-passive plug-in modules has a bi-color (green & red)LED status indicator located on the module front panel. The indicator islabeled PWR/ALM. If both colors are turned on, the indicator is yellow.Each plug-in module, except for the fan module, has its own alarm(fault) detection circuitry that controls the state of the PWR/ALM LED.The fan TACH signal of each fan module is monitored by the AMR.Based on the status of this signal, the AMR controls the state of thePWR/ALM LED on the fan module.LED Status Combinations forAll Modules (except GLI2,CSM, BBX2, MCC24, MCC8E)PWR/ALM LEDThe following list describes the states of the module status indicator.SSolid GREEN – module operating in a normal (fault free) condition.SSolid RED – module is operating in a fault (alarm) condition due toelectrical hardware failure.Note that a fault (alarm) indication may or may not be due to a completemodule failure and normal service may or may not be reduced orinterrupted.DC/DC Converter LED StatusCombinationsThe PWR CNVTR has alarm (fault) detection circuitry that controls thestate of the PWR/ALM LED. This is true for both the C–CCP and LPApower converters.PWR/ALM LEDThe following list describes the states of the bi-color LED.SSolid GREEN – module operating in a normal (fault free) condition.SSolid RED – module is operating in a fault (alarm) condition due toelectrical hardware problem.6

Appendix B: PN Offset Programming InformationMay 2000 B-1SC 4812T CDMA BTS Optimization/ATPPN Offset BackgroundAll channel elements transmitted from a BTS in a particular 1.25 MHzCDMA channel are orthonogonally spread by 1 of 64 possible Walshcode functions; additionally, they are also spread by a quadrature pair ofPN sequences unique to each sector.Overall, the mobile uses this to differentiate multiple signals transmittedfrom the same BTS (and surrounding BTS) sectors, and to synchronizeto the next strongest sector.The PN offset per sector is stored on the BBX2s, where thecorresponding I & Q registers reside.The PN offset values are determined on a per BTS/per sector(antenna)basis as determined by the appropriate cdf file content. A breakdown ofthis information is found in Table B-1.PN Offset UsageOnly the 14–chip delay is currently in use. It is important to determinethe RF chip delay to be able to test the BTS functionality. This can bedone by ascertaining if the CDF file FineTxAdj value was set to “on”when the MCC was downloaded with “image data”. The FineTxAdjvalue is used to compensate for the processing delay (approximately20 mS) in the BTS using any type of mobile meeting IS–97specifications.If the FineTxAdj value in the cdf file is 213 (D5 HEX), FineTxAdj hasbeen set for the 14 chip table.CDF file I and Q values can be represented in DECIMALor HEX. If using HEX, add 0x before the HEX value. Ifnecessary, convert HEX values in Table B-1 to decimalbefore comparing them to cdf file I & Q value assignments.IMPORTANT*B

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

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

Appendix D: BBX Gain Set Point vs. BTS Output ConsiderationsMay 2000 D-1SC 4812T CDMA BTS Optimization/ATPUsage & BackgroundTable D-1 outlines the relationship between the total of all code domainchannel element gain settings (digital root sum of the squares) and theBBX2 Gain Set Point between 33.0 dBm and 44.0 dBm. The resultantRF output (as measured at the top of the BTS in dBm) is shown in thetable. The table assumes that the BBX2 Bay Level Offset (BLO) valueshave been calculated.As an illustration, consider a BBX2 keyed up to produce a CDMAcarrier with only the Pilot channel (no MCCs forward link enabled).Pilot gain is set to 262.

Transmit & Receive Antenna VSWRMay 2000 G-1SC 4812T CDMA BTS Optimization/ATPPurposeThe following procedures will verify that the Voltage Standing WaveRatio (VSWR) of all antennas and associated feed lines fall withinacceptable limits. The tests will be performed on all antennas in asequential manner (i.e., ANT 1, then ANT 2) until all antennas/feedlineshave been verified.These procedures should be performed periodically by measuring eachrespective antenna’s VSWR (reflected power) to verify that the antennasystem is within acceptable limits. This will ensure continued peaksystem performance.The antenna VSWR will be calculated at the CDMA carrier frequencyassigned to each antenna. Record and verify that they meet the testspecification of less than or equal to 1.5:1.It is recommended that the installer be familiar with thefollowing procedure in its entirety before beginning theactual procedure. Ensure that the entire site is currently notin service.IMPORTANT*This test is used to test RX antennas by substituting RXfrequencies for TX frequencies.NOTEStudy the site engineering documents and perform the following testsonly after first verifying that the RF cabling configuration required tointerconnect the BTS frames and antennas meet requirements called outin the BTS Installation Manual.Test equipmentThe following pieces of test equipment will be required to perform thistest:SLMFSDirectional couplerSCommunications test setPrior to performing antenna tests, insure that no CDMABBX channels are keyed.
