Automated Acceptance Test Procedure - Introduction 68P09255A69-3Aug 20021X SCt4812ET Lite BTS Optimization/ATP Software Release 2.16.1.xPRELIMINARY4-2Automated Acceptance Test Procedure - IntroductionIntroductionGeneralThe Acceptance Test Procedures (ATP) allow Cellular Field Engineers(CFEs) to run automated acceptance tests on all BTS subsystem devicesequipped in the CDF using the LMF and the test equipment it supports.Test ReportsThe CFE can choose to save the results of ATP tests to a report file fromwhich ATP reports are generated for later printing. See the Generating anATP Report section in this chapter.Test Equipment SelectionBecause test equipment functions during acceptance testing arecontrolled by the LMF through the GPIB, only the test equipmentmodels supported by the LMF can be used.NOTE 1. Before using the LMF, read the Developer Release Notessection in the LMF Help function on-line documentation forany applicable information.2. The ATP test is to be performed on out-of-service sectorsonly.3. DO NOT substitute test equipment with other models notsupported by the LMF.Test Equipment Set CalibrationRefer to Chapter 3 for detailed interconnection information needed forcalibrating equipment, cables, and other test equipment set components.Reduced ATPNOTE Equipment has been factory-tested for FCC compliance. Iflicense-governing bodies require documentation supporting BTSsite compliance with regulations, a full ATP may be necessary.Perform the Reduced ATP only if reports for the specific BTSsite are NOT required.After downloading the proper operational software to the BTS, the CFEmust perform these procedures (minimum recommendation):1. Verify the TX/RX paths by performing TX Calibration, TX Audit,and FER tests.2. Retrieve Calibration Data required for normal site operation.Should failures occur while performing the specified tests, refer to theBasic Troubleshooting section of this manual for help in determining thefailure point. Once the point of failure has been identified and corrected,refer to the BTS Optimization and ATP Test Matrix (Table B-1) in theFRU Optimization/ATP Test Matrix section of Appendix B to determinethe applicable test that must be performed.4

These include the GLI, MCC, BBX, trunking modules, theLPAs, and passive components including splitters, combiners,bandpass filter(s), and RF cables.SAll RX: The RX test verifies the performance of the BTS receiveelements. These include the MPC, EMPC (for companion frames),BBX, MCC, GLI modules, and the passive components including RXfilters and RF cables.SAll TX/RX: Executes all TX and RX tests.SFull Optimization: Executes the TX calibration, downloads BLO,and executes the TX audit before running all TX and RX tests.ATP PrerequisitesBefore attempting to run any ATP tests, be sure the following have beencompleted:SBTS has been optimized (BBXs calibrated and BLOs downloaded)(Chapter 3)SThe carrier(s) and/or sector(s) to be tested have been taken out ofservice at the CBSC.SLMF is logged into the BTS.SCSMs, GLIs, BBXs, MCCs and TSU (if the RFDS is installed) havecorrect code and data loads.SPrimary CSM and GLI are INS_ACT (bright green).SMCCs are INS_ACT (bright green).SNo BBXs are keyed (transmitting).SBBXs are OOS_RAM (yellow).STest cables are calibrated.STest equipment has been selected, warmed up 60 minutes, andcalibrated.SGPIB is on.SBTS transmit connectors are properly terminated for the test(s) to beperformed.4
Automated Acceptance Test Procedure - Introduction 68P09255A69-3Aug 20021X SCt4812ET Lite BTS Optimization/ATP Software Release 2.16.1.xPRELIMINARY4-4WARNING 1. All transmit connectors must be properly terminated for allATP tests.2. Before the FER is run, be sure that one of the following isdone:- All transmitter connectors are properly terminatedOR- All LPAs are turned OFF (circuit breakers pulled)Failure to observe these warnings may result in bodily injury orequipment damage.TX/RX Antenna ConnectionsStarter (Stand-alone) FramesRefer to Figure 1-7 or Figure 1-8 for identification of starter frametransmit and receive antenna connections where measurements are to betaken. All ATP test equipment connections for starter frames are made atthe ANTENNAS connectors on the RF interface panel.Companion FramesTX ATP Antenna Connections - Each companion frame at a siteconnects independently to transmit antennas. Test equipmentconnections for TX ATPs on each companion frame are made at theANTENNAS connectors as on starter frames. Companion frameANTENNAS connectors are shown in Figure 1-9 and Figure 1-10.Antenna Connections for RX main ATP - Each companion frame at asite uses independent receive antennas for main RX signals. The mainRX signals are either routed through TRDC RX ANTENNASconnectors (Figure 1-10) or duplexed with TX signals through the singleDRDC ANTENNAS connectors (Figure 1-9).Antenna Connections for RX diversity ATP - Companion framediversity RX signals are obtained from the RX main antenna of thecollocated companion frame. The main RX signals are sent from thecollocated companion frame through inter-frame diversity RX cables tothe RX EXPANSION 1B, 2B, or 3B connectors of the frame where theyare used for diversity RX (refer to Figure 4-1). Diversity RX ATP testequipment connections are made at one of two different locationsdepending on whether or not the companion frame under test isconnected to a collocated companion frame. Connection points for eachsituation are as follows:SConnected companion frames: When inter-frame diversity RXcables are connected, connect test equipment for diversity RX ATP atthe ANTENNAS connectors of the collocated companion frame asshown in Figure 4-1 and listed in Table 4-1. Be sure MPC is selectedbefore logging the LMF into the frame or FER will fail.4

Failure to do so canresult in serious personal injury and/or equipment damage.NOTE The test equipment must be re-calibrated before using it toperform the TX Acceptance Tests.Acceptance Test Equipment Set UpAll ATP testing - Follow the steps in Table 4-3 to set up test equipmentfor all tests.Table 4-3: Set Up Test Equipment - TX Output Verify/Control TestsStep Action1If it has not already been done, interface the LMF computer to the BTS (refer to Table 3-10 andFigure 3-6).2If it has not already been done, refer to Table 3-11 to start a GUI LMF session and log into the BTS.3If it has not already been done, refer to Figure 3-16, Figure 3-17, Figure 3-18, Figure 3-19,Figure 3-20, or Figure 3-21, as applicable, for the test equipment and antenna duplexing being used, toconnect test equipment for acceptance testing.NOTELMF-based measurements factor in TX test cable loss between the RFMF and test equipment. Ifadditional attenuation, such as external TX combiners, is inserted in the path, it must be identified tothe LMF by including it in the TX test cable calibration. If this is not possible, include the attenuationin the TX path by editing cable loss values (refer to Table 3-34). Failure to do this will result in testinaccuracies and potential for erroneous ATP failures because the additional losses would not becompensated for in the test measurements. 4

Individual Acceptance Tests 68P09255A69-3Aug 20021X SCt4812ET Lite BTS Optimization/ATP Software Release 2.16.1.xPRELIMINARY4-14Individual Acceptance TestsThe following individual ATP tests can be used to evaluate specificaspects of BTS operation against individual performance requirements.All testing is performed using the LMF GUI environment.TX TestingTX tests verify any given transmit antenna path and output powercontrol. All tests are performed using the external, calibrated testequipment. All measurements are made at the appropriate BTS TX OUTconnector(s).TX tests verify TX operation of the entire CDMA forward link usingselected BBXs assigned to respective sector antennas. Each BBX iskeyed up to generate a CDMA carrier (using both bbxlevel and BLO)at the CDF file-specified carrier output power level.RX TestingRX testing verifies receive antenna paths for BBXs selected for the test.All tests are performed using the external, calibrated test equipment toinject a CDMA RF carrier with all zero longcode at the specified RXfrequency at the appropriate BTS RX IN connector(s).RX tests verify RX operation of the entire CDMA reverse link using allequipped MCCs assigned to all respective sector/antennas.Individual TestsSpectral Purity TX MaskThis test verifies that the transmitted CDMA carrier waveform generatedon each sector meets the transmit spectral mask specification (as definedin IS-97) with respect 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 in IS-97.Rho represents the correlation between the actual and perfect CDMAmodulation spectrums. 1.0000 represents 100% (or perfect correlation).Pilot Time OffsetThe Pilot Time Offset is the difference between the communicationssystem test set measurement interval (based on the BTS system timereference) and the incoming block of transmitted data from the BTS(Pilot only, Walsh code 0).Code Domain Power/Noise FloorThis 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 for IS-95A/B and CDMA2000 1Xwith respect to total CDMA channel power.4

All tests are performed using the external,calibrated test equipment controlled by the same command. Allmeasurements are made at the appropriate BTS TX antenna connector.CDMA Channel Test Set-up - Pilot gain will be set to 262 for eachantenna and the selected MCCs will be configured to supply allodd-numbered Walsh code traffic channel elements by enablingOrthogonal Channel Noise Source (OCNS) on all odd MCC channelelements (maximum 32 full rate channels with an OCNS gain of 81). Alleven-numbered Walsh code traffic channel elements will not haveOCNS enabled, and are considered “OFF”. Selected MCCs will beforward-link enabled for the antenna (sector) under test.Equipment Operation During Testing - The BBX will be keyed upusing a BLO-corrected bbxlvl value to generate a CDMA carrierconsisting of pilot and OCNS channels. RF output power, as measured atthe appropriate frame TX antenna connector, is set at one of thefollowing values depending on the operating frequency spectrum:S800 MHz: 33.5 dBmS1.9 GHz: 31.0 dBmTest Measurements - The test equipment will measure and return thechannel element power in dB of all specified Walsh channels within theCDMA spectrum. Additional calculations will be performed to verify thefollowing parameters are met (refer to Figure 4-3 for graphicrepresentations):STraffic channel element power level will be verified by calculating theratio of Pilot power to OCNS gain of all traffic channels (root sum ofthe square (RSS) of each OCNS gain divided by the Pilot power).This value should be 10.2 dB + 2.0 dB.SNoise floor (unassigned “OFF” even-numbered Walsh channels) isverified to be < -27 dB for IS-95A/B and CDMA2000 1X withrespect to total CDMA channel power.NOTE When performing this test using the LMF and the MCC is anMCC8E or MCC24E, the redundant BBX may fail or showmarginal performance. This is due to a timing mismatch that theLMF does not address. Performing this test from the CBSC willnot have this timing problem.Redundant BBX Testing - The BBX will then de-key, and if selected,the redundant BBX will be assigned to the current TX antenna pathunder test. The test will then be repeated for the redundant BBX. Uponcompletion of the test, OCNS channels will be disabled on the specifiedMCC channel elements.4

All tests are performed using the external, calibratedtest equipment as the signal source controlled by the same command.Measurements are made at the specified BTS RX antenna connection.Equipment Operation During Testing - The pilot gain on each MCCwill be set to 262 for each TX antenna, and the forward link for all TCHelements from the MCCs will be enabled. Appropriate BBX(s) must bekeyed in order to enable the RX receive circuitry. Operator-selectedBBXs will be keyed using only bbxlvl, to generate a CDMA carrierwith pilot channel element only. Transmit power output is set at -40dBm. Test equipment output power is set so that the received power atthe BBX is -119 dBm. The final output power setting of the testequipment takes into account the MPC type, BTS RF path losses, andtest cable losses. If selected, the redundant BBX will be assigned to thecurrent RX antenna paths under test.Test Measurements - The LMF will prompt the MCC channel elementunder test to measure all-zero longcode and provide the FER report onthe selected active MCC on the reverse link for the main and, if selected,diversity RX antenna paths. Results are evaluated to ensure they meetthe following specification:FER returned less than 1% and Total Frames measured is 1500Redundant BBX Testing - After the test, the BBX and the testequipment will be de-keyed to shut down the pilot signal and the activechannel element, respectively. If the redundant BBX was tested, BBXRassignment to an active sector will also be reset.Antenna Connections for Companion Frame RX Diversity Tests - Ata site equipped with companion frames, RX diversity for eachSC4812ET Lite frame is provided by the receive antennas for thecollocated companion frame. Because of this, performing FER oncompanion frame diversity RX requires different RX test cableconnections than on a starter frame. When performing companion framediversity RX FER, use Figure 4-1 and Table 4-1 or Table 4-2 todetermine the correct location for the RX test cable connections.4

Basic Troubleshooting: RF Path Fault Isolation 68P09255A69-3Aug 20021X SCt4812ET Lite BTS Optimization/ATP Software Release 2.16.1.xPRELIMINARY6-12Basic Troubleshooting: RF Path Fault IsolationOverviewThe optimization (RF path characterization or calibration) andpost-calibration (audit) procedures measure and limit-check the BTSreported transmit and receive levels of the path from each BBX to theback of the frame. When a fault is detected, it is specific to a receive ortransmit path. The troubleshooting process in this section determines themost probable cause of the fault.As the calibration and audit tests are performed, results are displayed inthe LMF test status report window. When faults are encountered, the testprocedure in progress continues running and displaying any furtherfaults. If it appears that there are major faults, the test can be aborted.The test results can be saved to a bts-#.rpt file in the<x>:\<lmf homedirectory \cdma\bts-# folder. To do this, close the test status reportwindow using the Save Results button.NOTE Closing the test status report window with the Dismiss buttonwill delete the test results without saving them.If a test is re-run or a new calibration, audit, or test is run and the resultsare saved, the previous test results in the bts-#.rpt file areoverwritten. To prevent losing previous test results in the bts-#.rptfile, refer to the procedure in Table 4-13 before performing furthertesting with the LMF.If there are major faults, recheck the test equipment attachments forerrors. If none are found, close the test status report window using theSave Results button, and save the contents of the resulting bts-#.rptfile as described in Table 4-13. Also, note other specifics about thefailure, and proceed with the fault isolation procedure.If Every Test FailsCheck the calibration equipment for proper operation by manuallysetting the signal generator output attenuator to the lowest output powersetting. Connect the output port to the spectrum analyzer RF input port.Set the signal generator output attenuator to -90 dBm, and switch on theRF output. Verify that the spectrum analyzer can receive the signal,indicate the correct signal strength (accounting for the cable insertionloss), and indicate the approximate frequency.Verify BLO CheckboxWhen performing a calibration with the TX Calibration... or AllCal/Audit... functions, the Verify BLO checkbox should normally bechecked. When a calibration fails, determine if any items such asdirectional couplers or combiners have been added to the TX path. Ifadditional items have been installed in the path, try re-running thecalibration with Verify BLO unchecked. If calibration still does notpass, refer to the following paragraphs and use the TX output faultisolation flowchart to identify the most probable cause of the failure.6

When acalibration fails with the redundant BBX selected, try re-running thecalibration with the Single-Sided BLO checkbox unchecked. If thecalibration still fails, refer to the following paragraphs and use the TXoutput fault isolation flowchart to identify the most probable cause of thefailure.If Faults Are IsolatedIf the fault reports are isolated between successful path checks, the rootcause of the faults most likely lies with one or more of the FieldReplaceable Unit (FRU) modules. If more than one failure was reported,look for a common denominator in the data. For example, if any TX testfails on one sector only, the BBX assigned to that sector (Table 1-5) is alikely cause. Also, look at the severity of the failure. If the path loss isjust marginally out of the relaxed specification limit during thepost-calibration TX audit, suspect excessive cable loss. If limits aremissed by a wide margin, suspect mis-wired cables or total devicefailure. Use the TX output fault isolation flowchart in Figure 6-1 toidentify the strongest possible cause for a failed TX test.Fault Isolation FlowchartThe flowchart covers the transmit path. Transmit paths usually fail thelower test limit, indicating excessive loss in some component in the BTSsite or mis-wiring. A failure of an upper limit usually indicates aproblem with the test setup or external equipment. Before replacing asuspected FRU, always repeat and verify the test results to rule out atransient condition. If a BBX fails an upper limit in the post-calibrationaudit procedure, re-calibrate and verify the out-of-tolerance conditionfor that BBX and/or sector before replacement.Flowchart PrerequisitesBefore entering the fault isolation sequence outlined in the flowchart, besure the following have been completed:SGLIs, MCCs, and BBXs have been downloaded with the correct ROMcode, RAM code, and data (Table 3-17, Table 3-18, and Table 3-19).SMGLI, CSMs, and MCCs are enabled (Table 3-18, Table 3-21, andTable 3-22, respectively)SBe sure the LED on the correct CCD card is solid green.SBe sure no alarms are being reported by opening an LMF alarmwindow as outlined in Table 3-53.6

The complexity of this board lendsitself to possible improper diagnoses when problems occur.Connector FunctionalityThe following connector overview describes the major types ofbackplane connectors along with the functionality of each. This willassist the CFE to:SDetermine which connector(s) is associated with a specific problemtype.SIsolate problems to a specific cable or connector.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 GLI in the SCCPshelf. The span line is used for MM/EMX switch control of the MasterGLI and also all the BBX traffic.Power Input (Return A and B connectors)Provides 27 volt input for use by the power supply modules.Power Supply Module InterfaceEach power supply module has a series of three different connectors toprovide the needed inputs/outputs to the SCCP backplane. These includea VCC/Ground input connector, a Harting-style multiple pin interface,and a +15V/Analog Ground output connector. The Transceiver PowerModule converts 27/48 Volts to a regulated +15, +6.5, +5.0 volts to beused by the SCCP shelf cards.GLI ConnectorThis connector consists of a Harting 4SU digital connector and a6-conductor coaxial connector for RDM distribution. The connectorsprovide inputs/outputs for the GLIs in the SCCP backplane.GLI Ethernet “A” and “B” ConnectionsThese SMB connectors are located on the SCCP backplane and connectto the GLI board. This interface provides all the control and datacommunications over the Ethernet LAN between the master GLI, theredundant GLI, and the LMF.BBX ConnectorEach BBX 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 BBXs in the SCCP backplane.6
Troubleshooting: SCCP Backplane68P09255A69-3Aug 2002 1X SCt4812ET Lite BTS Optimization/ATP Software Release 2.16.1.xPRELIMINARY6-21CIO ConnectorsSRF RX antenna path signal inputs are routed through RX paths of theDRDCs or TRDCs at the RF interface panel (rear of frame), andthrough coaxial cables to the two MPC modules. The three “A” (main)signals go to one MPC; the three “B” (diversity) to the other. TheMPC outputs the low-noise-amplified signals through the SCCPbackplane to the CIO where the signals are split and sent to theappropriate BBX.SA digital bus then routes the baseband signal through the BBX, to thebackplane, and then on to the MCC slots.SDigital TX antenna path signals originate at the MCCs. Each output isrouted from the MCC slot through the backplane to the appropriateBBX.STX RF path signal originates from the BBX, travels through thebackplane to the CIO, through the CIO, and then throughmulti-conductor coaxial cabling to the trunking module and LPAs inthe LPA shelf.SCCP Backplane Troubleshooting ProcedureThe following tables provide standard procedures for troubleshootingproblems that appear to be related to a defective SCCP backplane. Thetables are broken down into possible problems and steps which shouldbe taken in an attempt to find the root cause.NOTE All steps in all tables should be followed before any attempt toreplace the SCCP backplane.6

An outline of some basic guidelines isincluded in the following tables.NOTE Re-optimization steps listed for any assembly detailed in thetables below must be performed anytime an RF cable associatedwith it is replaced.Detailed Optimization/ATP Test MatrixTable B-1 outlines in more detail the tests that would need to beperformed if one of the BTS components were to fail and be replaced. Itis also assumes 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:NOTE Not every procedure required to bring the site back in service isindicated in Table B-1. It is meant to be used as a guidelineONLY. The table assumes that the user is familiar enough withthe BTS Optimization/ATP procedure to understand which testequipment set ups, calibrations, and BTS site preparation will berequired before performing the Table # procedures referenced.Passive BTS components (such as the bandpass filters and 2:1combiners) only require a TX calibration audit to be performed in lieu ofa full path calibration. If the TX path calibration audit fails, the entire RFpath calibration will need to be repeated. If the RF path calibration fails,further troubleshooting is warranted.NOTE If any significant change in signal level results from anycomponent being replaced in the RX or TX signal flow paths, itwould be identified by re-running the RX and TX calibrationaudit command.When the CIO is replaced, the SCCP shelf remains powered up. TheBBX 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 on the affected carriersectors.B

The resultantRF output (as measured in dBm at the BTS antenna connector) is shownin the table. The table assumes that the BBX Bay Level Offset (BLO)values have been calculated.As an illustration, consider a BBX keyed up to produce a CDMA carrierwith only the Pilot channel (no MCCs forward link enabled). Pilot gainis set to 262. In this case, the BBX Gain Set Point is shown to correlateexactly to the actual RF output anywhere in the 33 to 44 dBm outputrange. (This is the level used to calibrate the BTS).Table C-1: BBX Gain Set Point vs. Actual BTS Output (in dBm)dBm'Gainb44 43 42 41 40 39 38 37 36 35 34 33541 - - - - - - - 43.3 42.3 41.3 40.3 39.3533 - - - - - - - 43.2 42.2 41.2 40.2 39.2525 - - - - - - - 43 42 41 40 39517 - - - - - - - 42.9 41.9 40.9 39.9 38.9509 - - - - - - - 42.8 41.8 40.8 39.8 38.8501 - - - - - - - 42.6 41.6 40.6 39.6 38.6493 - - - - - - 43.5 42.5 41.5 40.5 39.5 38.5485 - - - - - - 43.4 42.4 41.4 40.4 39.4 38.4477 - - - - - - 43.2 42.2 41.2 40.2 39.2 38.2469 - - - - - - 43.1 42.1 41.1 40.1 39.1 38.1461 - - - - - - 42.9 41.9 40.9 39.9 38.9 37.9453 - - - - - - 42.8 41.8 40.8 39.8 38.8 37.8445 - - - - - 43.6 42.6 41.6 40.6 39.6 38.6 37.6437 - - - - - 43.4 42.4 41.4 40.4 39.4 38.4 37.4429 - - - - - 43.3 42.3 41.3 40.3 39.3 38.3 37.3421 - - - - - 43.1 42.1 41.1 40.1 39.1 38.1 37.1413 - - - - - 43 42 41 40 39 38 37405 - - - - - 42.8 41.8 40.8 39.8 38.8 37.8 36.8397 - - - - 43.6 42.6 41.6 40.6 39.6 38.6 37.6 36.6389 - - - - 43.4 42.4 41.4 40.4 39.4 38.4 37.4 36.4 . . . continued on next pageC
