Initial Power UpApr 2001 2-3SCt4812ET BTS Optimization/ATP — CDMA LMFDRAFTIntroductionThe following information is used to check for any electrical shortcircuits and to verify the operation and tolerances of the cellsite and BTSpower supply units before applying power for the first time. It containsinstructional information on the initial proper power up procedures forthe SC 4812ET power cabinet and RF cabinet. Also presented are teststo be preformed on the power cabinet. Please pay attention to allcautions and warning statements in order to prevent accidental injury topersonnel.Required ToolsThe following tools are used in the procedures.SDC current clamp (600 Amp capability with jaw size to accommodate2/0 cable).SHot Air Gun – (optional for part of the Alarm Verification)SDigital Multimeter (DMM)Cabling InspectionUsing the site-specific documentation generated by Motorola SystemsEngineering, verify that the following cable systems are properlyconnected:SReceive RF cabling – up to 12 RX cablesSTransmit RF cabling – up to six TX cablesFor positive power applications (+27 V):SThe positive power cable is red.SThe negative power cable is black. (The black powercable is at ground potential.)IMPORTANT*Initial Inspection and SetupEnsure all battery breakers for unused battery positions areopen (pulled out) during any part of the power up process,and remain in the off position when leaving the site.CAUTIONTable 2-2: Initial Inspection and SetupStep Action1Verify that ALL AC and DC breakers are turned OFF in both the Power and RF cabinets. Verify thatthe DC power cables between the Power and RF cabinets are connected with the correct polarity2The RED cables connect to the uppermost three (3) terminals (marked +) in both cabinets. Confirmthat the split phase 240/120 AC supply is correctly connected to the AC load center input.2
Initial Power Up – continuedDRAFTSCt4812ET BTS Optimization/ATP — CDMA LMF Apr 20012-4Failure to connect the proper AC feed will damage thesurge protection module inside the AC load center.CAUTIONPower Up SequenceThe first task in the power up sequence is to apply AC power to thePower cabinet. Once power is applied a series of AC Voltagemeasurements is required.Table 2-3: AC Voltage MeasurementsStep Action1Measure the AC voltages connected to the AC load center (access the terminals from the rear of thecabinet after removing the AC load center rear panel). See Figure 2-2.2Measure the AC voltage from terminal L1 to neutral. This voltage should be in the range of nominally115 to 120 V AC.3Measure the AC voltage from terminal L1 to ground. This voltage should be in the range of nominally115 to 120 V AC.4Measure the AC voltage from terminal L2 to neutral. This voltage should be in the range of nominally115 to 120 V AC.5Measure the AC voltage from terminal L2 to ground. This voltage should be in the range of nominally115 to 120 V AC.6Measure L1 – L2 – should be from 208 to 240 V AC. If the AC voltages are in excess of 120 V (or exceed200 V) when measuring between terminals L1 or L2 toneutral or ground, STOP and Do Not proceed until thecause of the higher voltages are determined. The powercabinet WILL be damaged if the Main breaker is turnedon with excessive voltage on the inputs.CAUTION2

Table 2-4 provides the procedure for applying ACpower.Table 2-4: Applying AC PowerStep Action1When the input voltages are verified as correct, turn the Main AC breaker (located on the front of theAC Load Center) ON. Observe that all eight (8) green LEDs on the front of the AC Load Center areilluminated (see Figure 2-7).2Turn Rectifier 1 and Rectifier 2 AC branch breakers (on the AC Load Center) ON. All the installedrectifier modules (see Figure 2-7) will start up and should each have two green LEDs (DC and Power)illuminated.3Turn the Meter Alarm Panel module, ON (see Figure 2-3), while observing the K2 contact in thePDA assembly (see Figure 2-9). The contact should close. The Meter Alarm Panel voltage metershould read approximately 27.4 + 0.2 Vdc.4Turn the Temperature Compensation Panel (TCP) ON, (see Figure 2-4). Verify that the Meter AlarmControl Panel does not have any alarm LEDs illuminated.5Check the rectifier current bargraph displays (green LED display on the rectifier module). Noneshould be illuminated at this point.If batteries are fitted, turn on the two battery heater ACbreakers on the AC Load Center.NOTE2

The voltage should read 27.4 + 0.2 Vdc. Adjust Master Voltage on MeterAlarm Panel if necessary. Release the TCP 25° C set button.2Depending on the ambient temperature, the voltage reading may now change by up to + 1.5 Vcompared to the reading just measured. If it is cooler than 25_C, the voltage will be higher, and if it iswarmer than 25_C, the voltage will be lower.3Ensure the RF cabinet 400 Amp main DC breaker is OFF.4Close the three (3) Main DC breakers on the Power Cabinet ONLY. Close by holding in the resetbutton on the front of the PDA, and engaging one breaker at a time.5Measure the voltage between the + and – terminals at the rear of the Power Cabinet and the RFCabinet, observing that the polarity is correct. The voltage should be the same as the measurement instep 2.6Place the probes across the black and red battery buss bars in each battery compartment. Place theprobe at the bottom of the buss bars where the cables are connected. The DC voltage should measurethe same as the previous step. 2
Initial Power Up – continuedApr 2001 2-7SCt4812ET BTS Optimization/ATP — CDMA LMFDRAFTDC Power Pre-test (BTS Frame) Before applying any power to the BTS cabinet, verify there are no shortsin the RF or power DC distribution system (see Figure 2-5).Table 2-6: DC Power Pre–test (BTS Frame)Step Action1Physically verify that all AC rectifiers supplying power to the RF cabinets are OFF or disabled (seeFigure 2-5). There should be no 27 Vdc on DC feed terminals.2On each RF cabinet:SUnseat all circuit boards/ modules in the distribution shelf, transceiver shelf, and Single CarrierLinear Power Amplifier (SCLPA) shelves, but leave them in their associated slots.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 – located on the power distribution panel).SSet LPA breakers to the OFF position by pulling out power distribution breakers (8 breakers,labeled 1A–1B through 4C–4D – located on the power distribution panel).3Verify that the resistance from the power (+) feed terminals with respect to the ground terminal on thecabinet measures > 500 Ω (see Figure 2-5).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 400 Amp Main Breaker and the C–CCP breakers (C–CCP 1, 2, 3) to the ON position bypushing them IN one at a time. Repeat step 3 after turning on each breaker.* IMPORTANTIf, after inserting any board/module, the ohmmeter stays at 0 Ω, 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 into their associated slots one at a time. Repeat step3after inserting each module.SA typical response is that the ohmmeter will steadily climb in resistance as capacitors charge, finallyindicating approximately 500 Ω.!

This process should becompleted quickly to avoid individual battery strings with excess charge currentNOTEIf the batteries are sufficiently discharged, the battery circuit breakers may not engage individuallydue to the surge current. If this condition is observed, turn off the Meter Alarm Panel power switch,and then engage all the connected battery circuit breakers, the Meter Alarm Panel power switchshould then be turned ON.2Using the DC current probe, measure the current in each of the battery string connections to the bussbars in each battery cabinet. The charge current may initially be high but should quickly reduce in afew minutes if the batteries have a typical new battery charge level.3The current in each string should be approximately equal (+ 5 A).4The bargraph meters on the rectifier modules can be used as a rough estimate of the total batterycharge current. Each rectifier module has eight (8) LEDs to represent the output current. Eachilluminated LED indicates that approximately 12.5% (1/8 or 8.75 A) of the rectifiers maximum (70 A)current is flowing.EXAMPLE:Question: A system fitted with three (3) rectifier modules each have three bargraph LEDsilluminated. What is the total output current into the batteries?Answer: Each bargraph is approximately indicating 12.5% of 70 A, therefore, 3 X 8.75 equals26.25 A. As there are three rectifiers, the total charge current is equal to (3 X 26.25 A) 78.75 A.This charge current calculation only applies at this part of the start up procedure, when the RF Cabinetis not powered on, and the power cabinet heat exchanger is turned off.5Allow a few minutes to ensure that the battery charge current stabilizes before taking any furtheraction. Recheck the battery current in each string. If the batteries had a reasonable charge, the currentin each string should reduce to less than 5 A.6Recheck the DC output voltage. It should remain the same as measured in step 4 of the Power UpTest.NOTEIf discharged batteries are installed, all bargraphs may be illuminated on the rectifiers during thecharge test. This indicates that the rectifiers are at full capacity and are rapidly charging the batteries.It is recommended in this case that the batteries are allowed to charge and stabilize as in the abovestep before commissioning the site. This could take several hours. Battery Discharge TestPerform the test procedure in Table 2-9 only when the battery current isless than 5 A per string. Refer to Table 2-8 on the procedures forchecking current levels.2

The rectifier outputvoltage and current should decrease by approximately 10% as the batteries assume the load. Alarmsfor the Meter Alarm Panel may occur.2Measure the individual battery string current using the DC current probe. The battery dischargecurrent in each string should be approximately the same (within + 5 A).3Turn Battery Test Switch OFF.Failure to turn OFF the Battery Test Switch before leavingthe site, will result in low battery capacity and reducebattery life.CAUTIONHeat Exchanger Power UpTable 2-10: Heat Exchanger Power UpStep Action1Turn the Power Cabinet Heat Exchanger breakers ON (seeFigure 2-6 for breaker location).2The Heat Exchanger will now go into a 5 minute test sequence.

Optimization/Calibration – IntroductionApr 2001 3-1SCt4812ET BTS Optimization/ATP — CDMA LMFDRAFTIntroductionThis chapter provides procedures for downloading system operatingsoftware, set up of the supported test equipment, CSM referenceverification/optimization, and transmit/receive path verification.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 CDMA LMF is used to calibrateand optimize the BTS. The basic optimization process can beaccomplished as follows:SDownload MGLI2–1 with code and data and then enable MGLI2–1.SUse the status function and verify that all of the installed devices ofthe following types respond with status information: CSM2, 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 CDF filewill have to be corrected before the device can be accessed by CDMALMF.SDownload code and data to all devices of the following types:– CSM2– BBX–GLI2 (other than MGLI2–1)– MCCSDownload the RFDS TSIC (if installed).SVerify the operation of the GPS and HSO signals.SEnable the following devices (in the order listed):–Secondary CSM (slot 2)–Primary CSM (slot 1)–All MCCsSConnect the required test equipment for a full optimization.SSelect the test equipment.SCalibrate 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 – continuedDRAFTSCt4812ET BTS Optimization/ATP — CDMA LMF Apr 20013-2SSelect 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.SIf the TX calibration fails, repeat the full optimization for any failedpaths.SIf the TX calibration fails again, correct the problem that caused thefailure and repeat the full optimization for the failed path.SIf the TX calibration and audit portion of the full optimization passesfor a path but some of the TX or RX tests fail, correct the problem thatcaused the failure and run the individual tests as required until all TXand 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.Cell–site Data File 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–MCC (MCC24E, MCC8E or MCC–1X) channel element allocationplan. This plan indicates how the C–CCP shelf is configured, andhow the paging, synchronization, traffic, and access channelelements (and associated gain values) are assigned among the (up to12) MCCs in the shelf.SCSM equipage including redundancySEffective 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, 68P64114A78,for additional information on the layout of the LMFdirectory structure (including CDF file locations andformats).NOTE3
Optimization/Calibration – Introduction – continuedApr 2001 3-3SCt4812ET BTS Optimization/ATP — CDMA LMFDRAFTBTS 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,68P64114A78, or the LMF Help screen, for more information.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 to the actual site hardware.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 LMFDRAFTSCt4812ET BTS Optimization/ATP — CDMA LMF Apr 20013-4Isolate BTS from T1/E1 Spans–At active sites, the OMC/CBSC must disable theBTS and place it out of service (OOS). DO NOTremove the span surge protectors until theOMC/CBSC has disabled the BTS.IMPORTANT*Each frame is equipped with one 50–pair punch block for spans,customer alarms, remote GPS, and power cabinet alarms. See Figure 3-2and refer to Table 3-1 for the physical location and pin call–outinformation. To disable the span, pull the surge protectors for therespective span.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.Configure Channel ServiceUnitThe M–PATH 537 Channel Service Unit (CSU) provides in–bandSNMP–managed digital service access to T1 and fractional T1 lines.M–PATH units plug into the ADC Kentrox 2–slot frame (seeFigure 3-1).Remote M–PATH management is available via SNMP over an in–banddata link on the T1 line (using a facility data link or 8–64 Kbps of a DS0channel). The unit at the near end of the management path can be anSNMP manager or another M–PATH CSU.Each 19 inch rack can support two CSU M–PATH 537 modules. EachM–PATH 537 module supports one and only one span connection.Programming of the M–PATH is accomplished through the DCE 9–pinconnector on the front panel of the CSU shelf. Manuals and a MicrosoftWindows programming disk is supplied with each unit.3

Perform the DeviceImages install after the WinLMF installation.If applicable, a separate CD ROM of BTS Binaries may be available for binary updates. CDMA LMF Home DirectoryThe CDMA LMF installation program creates the default home directoryc:\wlmf, and installs the application files and subdirectories (folders)in it. Because this can be changed at installation, the CDMA LMF homedirectory will be referred to with the generic convention of:<x>:\<lmf home directory>Where:<x> = the LMF computer drive letter where the CDMA LMF homedirectory is located.<lmf home directory> = the directory path or name where the CDMALMF is installedThe CDMA LMF installation program creates the defaulthome directory c:\wlmf when the CDMA LMF isinstalled.NOTE3
Preparing the LMF – continuedDRAFTSCt4812ET BTS Optimization/ATP — CDMA LMF Apr 20013-12Copy CBSC CDF Files to theLMF ComputerBefore logging on to a BTS with the LMF to execute optimization/ATPprocedures, the correct bts-#.cdf and cbsc–#.cdf files must be obtainedfrom the CBSC and put in a bts-# folder in the LMF computer. Thisrequires creating versions of the CBSC CDF files on a DOS–formattedfloppy diskette and using the diskette to install the CDF files on theLMF computer.*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 willwork with locally numbered BTS CDF files. Using this filewill not provide a valid optimization unless the generic fileis edited to replace default parameters (e.g., channelnumbers) with the operational parameters used locally.IMPORTANTThe procedure in Table 3-4 lists the steps required to transfer the CDFfiles from the CBSC to the LMF computer. For any further information,refer to the CDMA LMF Operator’s Guide (Motorola part number68P64114A21) or the LMF Help screen..Table 3-4: Copying CBSC CDF Files to the LMFStep Action1Login to the CBSC workstation.2Insert a DOS–formatted floppy diskette in the workstation drive.3 Type eject –q and press <Enter>.4 Type mount and press <Enter>.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.

Preparing the LMF – continuedDRAFTApr 2001 3-13SCt4812ET BTS Optimization/ATP — CDMA LMFTable 3-4: Copying CBSC CDF Files to the LMFStep Action7 With Solaris versions of Unix, create DOS–formatted versions of the bts–#.cdf and cbsc–#.cdf fileson the diskette by entering the following command:unix2dos <source filename> /floppy/no_name/<target filename>(e.g., unix2dos bts–248.cdf /floppy/no_name/bts–248.cdf).NOTESOther versions of Unix do not support the unix2dos and dos2unix commands. In these cases, use theUnix cp (copy) command. The copied files will be difficult to read with a DOS or Windows texteditor because Unix files do not contain line feed characters. Editing copied CDF files on the LMFcomputer 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 <Enter>.10 Remove the diskette from the CBSC drive.11 If it is not running, start the Windows operating system on the LMF computer.12 Insert the diskette containing the bts–#.cdf and cbsc–#.cdf files into the LMF computer.13 Using Windows Explorer (or equivalent program), create a corresponding bts–# folder in the <lmfhome directory> 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 from thediskette to the corresponding <lmf home directory>\wlmf\cdma\bts–# folders created in step 13. Creating a NamedHyperTerminal Connection forMMI ConnectionConfirming or changing the configuration data of certain BTS FRUsrequires establishing an MMI communication session between the LMFand the FRU. Using features of the Windows operating system, theconnection properties for an MMI session can be saved on the LMFcomputer as a named Windows HyperTerminal connection. Thiseliminates the need for setting up connection parameters each time anMMI session is required to support optimization.Once the named connection is saved, a shortcut for it can be created onthe Windows desktop. Double clicking the shortcut icon will start theconnection without the need to negotiate multiple menu levels.Follow the procedures in Table 3-5 to establish a named HyperTerminalconnection and create a Windows desktop shortcut for it.3

The CLI environment provides additional capability to theuser to perform manually controlled acceptance tests and audit theresults of optimization and calibration actions.Basic operation of the LMF GUI includes the following:SSelecting and deselecting BTS devicesSEnabling devicesSDisabling devicesSResetting devicesSObtaining device statusSSorting a status report windowFor detailed information on performing these and other LMF operations,refer to the CDMA LMF Operator’s Guide, 68P64114A78.Basic LMF Command LineInterface (CLI) Operation.Both the GUI and the CLI use a program known as the handler. Only onehandler can be running at one time. The architectural design is such thatthe GUI must be started before the CLI if you want the GUI and CLI touse the same handler. When the CLI is launched after the GUI, the CLIautomatically finds and uses an in–progress login session with a BTSinitiated under the GUI. This allows the use of the GUI and the CLI inthe same BTS login session. If a CLI handler is already running whenthe GUI is launched (this happens if the CLI window is already runningwhen the user starts the GUI, or if another copy of the GUI is alreadyrunning when the user starts the GUI), a dialog window displays thefollowing warning message:The CLI handler is already running.This may cause conflicts with the LMF.Are you sure that you want to start the application?This window also contains yes and no buttons. Selecting yes starts theapplication. Selecting no terminates the application.3

Download the BTS – continuedDRAFTSCt4812ET BTS Optimization/ATP — CDMA LMF Apr 20013-30Enable 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 used as the primary timing reference andsynchronizes the entire cellular system. CSM 2 provides redundancy (butdoes not have a GPS receiver).The BTS may be equipped with a LORAN–C LFR, HSO, or external 10MHz Rubidium source which the CSM can use as a secondary timingreference. In all cases, the CSM monitors and determines what referenceto use at a given time.For RF–GPS, verify the CSM configured with the GPSreceiver “daughter board” is installed in the frame’s CSM 1slot before continuing.IMPORTANT*Follow the steps outlined in Table 3-16 to enable the CSMs installed inthe C–CCP shelves.Table 3-16: Enable CSMsStep Action1Click on the target CSM.From the Device pull down, select Enable.NOTEIf equipped with two CSMs, enable CSM–2 firstA status report is displayed confirming change in the device(s) status.Click OK to close the status report window.NOTEFAIL may be shown in the status table for enable action. If Waiting For Phase Lock is shown in theDescription field, the CSM changes to the Enabled state after phase lock is achieved.CSM 1 houses the GPS receiver. The enable sequence can take up to one hour (see below).* IMPORTANTThe GPS satellite system satellites are not in a geosynchronous orbit and are maintained and operatedby the United States Department of Defense (D.O.D.). The D.O.D. periodically alters satellite orbits;therefore, satellite trajectories are subject to change. A GPS receiver that is INS contains an “almanac”that is updated periodically to take these changes into account.If a GPS receiver has not been updated for a number of weeks, it may take up to an hour for the GPSreceiver “almanac” to be updated.Once updated, the GPS receiver must track at least four satellites and obtain (hold) a 3–D position fixfor a minimum of 45 seconds before the CSM will come in service. (In some cases, the GPS receiverneeds to track only one satellite, depending on accuracy mode set during the data load).. . . continued on next page3

CSM System Time – GPS & LFR/HSO VerificationDRAFTSCt4812ET BTS Optimization/ATP — CDMA LMF Apr 20013-32Clock SynchronizationManager System TimeThe 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.The CSM2 card (CSM second generation) is required when using theremote GPS receiver (R–GPS). R–GPS uses a GPS receiver in theantenna head that has a digital output to the CSM2 card. CSM2 can havea daughter card 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 Distribution Cards(CCDs) buffer and distribute even–second reference and 19.6608 MHzclocks. CCD 1 is married to CSM 1 and CCD 2 is married to CSM 2. Afailure on CSM 1 or CCD 1 cause the system to switch to redundantCSM 2 and CCD 2.Each CSM2 board features an ovenized, crystal oscillator that provides19.6608 MHz clock, even second pulse, and 3 MHz referenced to theselected synchronization source (see Table 3-19):SGPS: local/RF–GPS or remote/R–GPSSLORAN–C Frequency Receiver (LFR) or High Stability Oscillator(HSO)SExternal reference oscillator sourcesFault 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 3-19). The sourceselection can also be overridden via the LMF or by the system software.Synchronization between the primary and redundant CSM CCD pairs, aswell as the LFR or HSO back–up to GPS synchronization, increasesreliability.Low 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 indefinately after initial GPS lock.3
CSM System Time – GPS & LFR/HSO Verification – continuedApr 2001 3-33SCt4812ET BTS Optimization/ATP — CDMA LMFDRAFTThe 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 3-19).HSO, HSO2, and HSOX use the same source code in source selection(see Table 3-19).Allow the base site and test equipment to warm up for60 minutes after any interruption in oscillator power.CSM board warm-up allows the oscillator oventemperature and oscillator frequency to stabilize prior totest. Test equipment warm-up allows the Rubidiumstandard timebase to stabilize in frequency before anymeasurements are made.NOTE3

Test Set CalibrationDRAFTSCt4812ET BTS Optimization/ATP — CDMA LMF Apr 20013-50BackgroundProper test equipment setup 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*PurposeThese procedures access the CDMA LMF automated calibration routineused to determine the path losses of the supported communicationsanalyzer, power meter, associated test cables, and (if used) antennaswitch that make up the overall calibrated test set. After calibration, thegain/loss offset values are stored in a test measurement offset file on theCDMA LMF.3

A status window is displayed.4Click on OK to close the status report window.Calibrating CablesThe cable calibration function is used to measure the loss (in dB) for theTX and RX cables that are to be used for testing. A CDMA analyzer isused to measure the loss of each cable configuration (TX cableconfiguration and RX cable configuration). The cable calibrationconsists of the following steps.SMeasure the loss of a short cable. This is done to compensate for anymeasurement error of the analyzer. The short cable, which is used onlyfor the calibration process, is used in series with both the TX and RXcable configuration when they are measured. The measured loss of theshort cable is deducted from the measured loss of the TX and RXcable configuration to determine the actual loss of the TX and RXcable configurations. This deduction is done so any error in theanalyzer measurement will be adjusted out of both the TX and RXmeasurements.SThe short cable plus the RX cable configuration loss is measured. TheRX cable configuration normally consists only of a coax cable withtype–N connectors that is long enough to reach from the BTS RX portthe test equipment.SThe short cable plus the TX cable configuration loss is measured. TheTX cable configuration normally consists of two coax cables withtype–N connectors and a directional coupler, a load, and an additionalattenuator if required by the BTS type. The total loss of the path lossof the TX cable configuration must be as required for the BTS(normally 30 or 50 dB). The Motorola Cybertest analyzer is differentin that the required attenuation/load is built into the test set so the TXcable configuration consists only of the required length coax cable.3

Bay Level Offset CalibrationApr 2001 3-59SCt4812ET BTS Optimization/ATP — CDMA LMFDRAFTIntroductionCalibration 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 the CAL file. TheBLOs are subsequently downloaded to each BBX2.Each receive path starts at a BTS RX antenna port and terminates at abackplane BBX2 slot. Each transmit path starts at a BBX2 backplaneslot, travels through the LPA, and terminates at a BTS TX antenna port.Calibration identifies the accumulated gain in every transmit path(BBX2 slot) at the BTS site and stores that value in the CAL file. Eachtransmit 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 will automatically be set tothe default value.When to Calibrate BLOs Calibration of BLOs is required after initial BTS installation.The BLO data of an operational BTS site must be re-calibrated onceeach year. Motorola recommends re-calibrating the BLO data for allassociated RF paths after replacing any of the following components orassociated interconnecting RF cabling:SBBX2 boardSC–CCP shelfSCIO cardSCIO to LPA backplane RF cableSLPA backplaneSLPASTX filter / TX filter combinerSTX thru-port cable to the top of frame3
Bay Level Offset Calibration – continuedDRAFTSCt4812ET BTS Optimization/ATP — CDMA LMF Apr 20013-60TX Path CalibrationThe TX Path Calibration assures correct site installation, cabling, and thefirst order functionality of all installed equipment. 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 – continuedApr 2001 3-61SCt4812ET BTS Optimization/ATP — CDMA LMFDRAFTBLO Calibration Data FileDuring the calibration process, the LMF creates a calibration (BLO) datafile. After calibration has been completed, this offset data must bedownloaded to the BBX2s using the Download BLO function. Anexplanation 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 (see Table 3-31).Each BBX2 slot header 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.

As you can see, 10 calibrationpoints per sector are supported for each branch. Two entries arerequired for each calibration point.SThe first value (all odd entries) refer to the CDMA channel(frequency) the BLO is measured at. The second value (all evenentries) is the power set level. The valid range for PwrLvlAdj is from2500 to 27500 (2500 corresponds to –125 dBm and 27500corresponds to +125 dBm).3
Bay Level Offset Calibration – continuedApr 2001 3-63SCt4812ET BTS Optimization/ATP — CDMA LMFDRAFTSThe 20 calibration entries for each slot/branch combination must bestored in order of increasing frequency. If less than 10 points(frequencies) are calibrated, the largest frequency that is calibrated isrepeated to fill out the 10 points.Example:C[1]=384, odd cal entry = 1 ‘‘calibration point”C[2]=19102, even cal entryC[3]=777,C[4]=19086,..C[19]=777,C[20]=19086, (since only two cal points were calibrated this would be repeated for the next 8 points)SWhen the BBX2 is loaded with BLO data, the cal file data for theBBX2 is downloaded to the device in the order it is stored in the CALfile. TxCal data is sent first, C[1] – C[60]. BBX2 slot 1’s 10calibration points are sent (C[1] – C[20]), followed by BBX2 slot 2’s10 calibration points (C[21] – C[40]), etc. The RxCal data is sent next,followed by the RxDCal data.STemperature compensation data is also stored in the cal file for eachslot.Test Equipment Setup:RF Path CalibrationFollow the steps outlined in Table 3-32 to set up test equipment.Table 3-32: Test Equipment Setup (RF Path Calibration)Step ActionNOTEVerify the GPIB is properly connected and turned on.! CAUTIONTo prevent damage to the test equipment, all transmit (TX) test connections must be via the 30 dBdirectional coupler for 800 MHz or via a 30 dB coupler with a 20 dB in–line attenuator for 1900 MHz.1Connect the LMF computer terminal to the BTS LAN A connector on the BTS (if you have notalready done so). Refer to the procedure in Table 3-6.SIf required, calibrate the test equipment per the procedure in Table 3-24.SConnect the test equipment as shown in Figure 3-9 and Figure 3-10.3
Bay Level Offset Calibration – continuedDRAFTSCt4812ET BTS Optimization/ATP — CDMA LMF Apr 20013-64Transmit (TX) Path CalibrationThe assigned channel frequency and power level (as measured at the topof the frame) for transmit calibration is derived from the site CDF file.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).The 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). The All Cal/Auditmenu item performs TX calibration, downloads BLO, and performs TXaudit if the TX calibration passes. All measurements are made throughthe appropriate TX output connector using the calibrated TX cable setup.PrerequisitesBefore running this test, ensure that the following have been done:SCSM–1,GLIs, MCCs, and BBX2s have correct code load and dataload.SPrimary CSM and MGLI are INS.SAll BBX2s are OOS_RAM.STest equipment and test cables are calibrated and connected for TXBLO calibration.SLMF is logged into the BTS.Connect the test equipment as shown in Figure 3-9 and Figure 3-10 andfollow the procedure in Table 3-33 to perform the TX calibration test.3
