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

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

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

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.Cellsite TypesSites are configured as with a maximum of 4 carriers, 3–sectored with amaximum of 4 carriers, and 6–sectored with a maximum of 2 carriers.Each type has unique characteristics and must be optimized accordingly.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 andMCC24E/MCC8E boards (per cage), and linear power amplifierassignments are some of the equipage data included in the CDF.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–static bag itwas shipped in.CAUTIONInitial Installation ofBoards/ModulesTable 2-1: Initial Installation of Boards/ModulesStep Action1Refer to the site documentation and install all boards and modules into the appropriate shelves asrequired. Verify they are NOT SEATED at this time.2As the actual site hardware is installed, record the serial number of each module on a “Serial NumberChecklist” in the site logbook.2
