Optimization Manual: Scope and LayoutMar 2001 1-1SCt4812T CDMA BTS Optimization/ATP DRAFTScope 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 Code Division Multiple Access (CDMA) LocalMaintenance Facility (LMF) capability comes on–line,applicable LMF based procedures will be incorporated.Eventually, only the CDMA LMF platform will besupported as the recommended customer method ofinterfacing with and servicing the SC series BTSequipment.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 OptimizationDRAFTSCt4812T CDMA BTS Optimization/ATP Mar 20011-4Why 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 CDMA Channel Processor (C–CCP) backplane BroadBand Transceiver (BBX) slot in the 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 BBX slotin the C–CCP shelf.SThe TX path starts at the BBX, 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 – continuedMar 2001 1-5SCt4812T CDMA BTS Optimization/ATP DRAFTThese 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, 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 EquipmentDRAFTSCt4812T CDMA BTS Optimization/ATP Mar 20011-6PolicyThe 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 RFDScalibration procedures.SCommunications Test SetSRubidium Time BaseSPower Meter1

BTS Equipment IdentificationMar 2001 1-13SCt4812T CDMA BTS Optimization/ATP DRAFTEquipment OverviewThe Motorola SC 4812T BTS can consist of the following equipmentframes:SAt least one BTS starter frame–+27 V BTS (see Figure 1-2)––48 V BTS (see Figure 1-3)SAncillary equipment frame (or wall mounted equipment)SExpansion frames–+27 V BTS (see Figure 1-4)––48 V BTS (see Figure 1-5)Ancillary Equipment FrameIdentificationEquipment listed below can be wall mounted or mountedin a standard 19 inch frame. The description assumes thatall equipment is mounted in a frame for clarity.NOTEIf equipped with the RFDS option, the RFDS and directional couplersare the interface between the site antennas and the BTS or Modemframe. The RFDS equipment includes:SDirectional couplersSSite receive bandpass/bandreject filtersSRFDSLogical BTSThe BTS software implements the logical BTS capability. Previously, allBTS frames co–located at a single site had to be identified in thenetwork with separate and distinct BTS ID numbers. In the Logical BTSfeature, all frames located at a single BTS site are identified with uniqueFrame ID numbers (Frame ID Numbers 1, 101, 201, 301) under a single(site) BTS ID number. A logical BTS can consist of up to fourSC 4812T frames.When the LMF is connected to frame 1 of a logicalBTS, you can access all devices in all of the frames that make up thelogical BTS. A logical BTS requires a CDF file that includes equipageinformation for all of the logical BTS frames and their devices and aCBSC file that includes channel data for all of the logical BTS fames. . . . continued on next page1
BTS Equipment Identification – continuedDRAFTSCt4812T CDMA BTS Optimization/ATP Mar 20011-14Logical 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.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.
