Preliminary Operations: OverviewMar 2001 2-1SCt4812T CDMA BTS Optimization/ATP DRAFTIntroductionThis 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, BBX boards, MCC boards(per cage), and linear power amplifier assignments are some of theequipage 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 TestsDRAFTSCt4812T CDMA BTS Optimization/ATP Mar 20012-4ObjectiveThis procedure checks for any electrical short circuits and verifies theoperation and tolerances of the cellsite and BTS power supply units priorto applying power for the first time.Test EquipmentThe following test equipment is required to complete the pre–power–uptests:SDigital Multimeter (DMM)Always wear a conductive, high impedance wrist strapwhile handling the any circuit card/module to preventdamage by ESD.CAUTIONCabling 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 cablesSGPSSLFRFor positive power applications (+27 V):SThe positive power cable is red.SThe negative power cable (ground) is black.For negative power applications (–48 V):SThe negative power cable is red or blue.SThe positive power cable (ground) is black.In all cases, the black power cable is at ground potential.IMPORTANT*2
Pre–Power–up Tests – continuedMar 2001 2-5SCt4812T CDMA BTS Optimization/ATP DRAFTDC 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 thepower conversion 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.!

Optimization/Calibration – IntroductionMar 2001 3-1SCt4812T CDMA BTS Optimization/ATP DRAFTIntroductionThis section describes procedures for isolating the BTS from the spanlines, preparing and using the LMF, downloading system operatingsoftware, CSM reference verification/optimization, set up and calibrationof the supported test equipment, transmit/receive path verification, usingthe RFDS, and verifying the customer defined alarms and relay contactsare functioning properly.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, BBX,GLI2, MCC, and TSU (if RFDS is installed). If a device is installedand powered up but is not responding and is colored gray in the BTSdisplay, the device is not listed in the CDF file. The CDF file willhave to be corrected before the device can be accessed by the LMF.3. Download code and data to all devices of the following types:–CSM–BBX (may be BBX2 or BBX–1X)–GLI2 (other than MGLI2–1)–MCC (may be MCC–8E, MCC24, or MCC–1X)4. 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 – continuedDRAFTSCt4812T CDMA BTS Optimization/ATP Mar 20013-210. 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 FileThe Cell–SiteData File (CDF) contains information that defines the BTSand data used to download files to the devices. A CDF file must beplaced in the applicable BTS folder before the LMF can be used to loginto that BTS. CDF files are normally obtained from the CBSC using afloppy disk. A file transfer protocol (ftp) method can be used if the LMFcomputer has that capability. The CDF includes the following information:SDownload instructions and protocolSSite specific equipage informationSC–CCP shelf allocation plan–BBX 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 redundancy . . . continued on next page3
Optimization/Calibration – Introduction – continuedMar 2001 3-3SCt4812T CDMA BTS Optimization/ATP DRAFTSEffective 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 BBX 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).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 LMFDRAFTSCt4812T CDMA BTS Optimization/ATP Mar 20013-4Isolate 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. A GLI2card can support up to six spans. In the SC 4812T configuration, the oddspans (1, 3, and 5) terminate on the Span ”A” I/O; and the even spans (2,4, and 6) terminate on the Span ”B” I/O.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.NOTEIf a third party is used for span connectivity, the third party must be informed before disconnecting thespan line.* IMPORTANTVerify that you remove the SPAN cable, not the “MODEM/TELCO” connector.3

Preparing the LMF – continuedDRAFTSCt4812T CDMA BTS Optimization/ATP Mar 20013-8Table 3-3: LMF Operating System InstallationnActionStep5Follow the instructions displayed on the Setup screen.* IMPORTANTFirst Time Installations:–Install U/WIN (First)–Install Java Runtime Environment (Second)–Install LMF Software (Third)–Install BTS Binaries (Fourth)–Install/Create BTS Folders (Fifth)Any time you install U/WIN, you must install the LMF software because the installation of theLMF modifies some of the files that are installed during the U/Win installation. Installing U/Winover–writes these modifications.NOTEThere are multiple binary image packages for installation on the CD–ROM. When prompted,choose the load that corresponds to the switch release that you currently have installed. Performthe Device Images install after the WinLMF installation.If applicable, a separate CD ROM of BTS Binaries may be available for binary updates. Copy CDF Files from CBSCBefore the LMF can execute the optimization/ATP procedures for theBTS, the correct bts-#.cdf and cbsc-#.cdf files must beobtained from the CBSC and put in a bts-# folder in the LMFnotebook. This requires copying the CBSC CDF files to a DOSformatted diskette, and using the diskette to install the CDF file in theLMF.Follow the procedure in Table 3-4 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 number68P64114A78) 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 . . . continued on next page3
Preparing the LMF – continuedMar 2001 3-9SCt4812T CDMA BTS Optimization/ATP DRAFT*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 3-4: 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 anumber. Use the explicit floppy/no_name reference displayed when performing step 7.5Change to the directory containing the file by typing cd <directory name> (ex. cdbts–248) and pressing <Enter>.6 Type ls <Enter> to display the list of files in the directory.7 With Solaris versions of Unix, create DOS–formatted versions of the bts–#.cdf and cbsc–#.cdffiles on 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 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).. . . continued on next page3

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.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 procedure in Table 3-5 to establish a named HyperTerminalconnection and create a WIndows desktop shortcut for it.There are differences between Windows NT and Windows98 in the menus and screens for creating a HyperTerminalconnection.

Using CDMA LMFDRAFTSCt4812T CDMA BTS Optimization/ATP Mar 20013-18Basic LMF OperationThe CDMA LMF allows the user to work in the two following operatingenvironments, which are accessed using the specified desktop icon:SGraphical User Interface (GUI) using the WinLMF iconSCommand Line Interface (CLI) using the WinLMF CLI iconThe GUI is the primary optimization and acceptance testing operatingenvironment. 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.Graphical User InterfaceOverviewThe LMF uses a GUI, which works in the following 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.3
Using CDMA LMF – continuedDRAFTMar 2001 3-19SCt4812T CDMA BTS Optimization/ATPCommand Line InterfaceOverviewThe LMF also provides Command Line Interface (CLI) capability.Activate the CLI by clicking on a shortcut icon on the desktop. The CLIcan not be launched from the GUI, only from the desktop icon.Both the GUI and the CLI use a program known as the handler. Only onehandler can be running at one time Due to architectural limitations, theGUI must be started before the CLI if you want the GUI and CLI to usethe 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.CLI Format ConventionsThe CLI command can be broken down in the following way:SverbSdevice including device identifier parametersSswitchSoption parameters consisting of:–keywords–equals signs (=) between the keywords and the parameter values–parameter valuesSpaces are required between the verb, device, switch, and optionparameters.

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 nothave a GPS receiver.The BTS may be equipped with a remote GPS, LORAN–C LFR, orHSO 10 MHz Rubidium source, which the CSM can use as a secondarytiming reference.

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 3-19 and Table 3-20 to determine the cause.3

CSM System Time/GPS and LFR/HSO VerificationMar 2001 3-33SCt4812T CDMA BTS Optimization/ATP DRAFTCSM & 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 3-19). 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 3-36 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 – continuedDRAFTSCt4812T CDMA BTS Optimization/ATP Mar 20013-34Low 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 3-18).HSO, HSO2, and HSOX use the same source code in source selection(see Table 3-18).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.

Test Set CalibrationDRAFTSCt4812T CDMA BTS Optimization/ATP Mar 20013-54Test 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 CalibrationDRAFTSCt4812T CDMA BTS Optimization/ATP Mar 20013-64Introduction 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 (BBXslot) at the BTS site and stores that value in a BLO database calibrationtable in the LMF. The BLOs are subsequently downloaded to each BBX.For starter frames, each receive path starts at a BTS RX antenna port andterminates at a backplane BBX slot. Each transmit path starts at a BBXbackplane slot, travels through the LPA, and terminates at a BTS TXantenna 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 BBX slot of the expansion frame.The transmit path starts at a BBX backplane slot of the expansion frame,travels though the LPA, and terminates at a BTS TX antenna port of thesame expansion frame.Calibration identifies the accumulated gain in every transmit path (BBXslot) at the BTS site and stores that value in a BLO database. Eachtransmit path starts at a C–CCP shelf backplane BBX 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, BBX slots 1 and 13 (redundant) are tested. At sector sites,BBX slots 1 through 12, and 13 (redundant) are tested. Only those slots(sectors) actually equipped in the current CDF are tested, regardless ofphysical BBX 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:–BBX board–C–CCP shelf–CIO card–CIO to LPA backplane RF cable–LPA backplane–LPA . . . 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 BBX boards), move BBX boards from shelvescurrently not under test and install them into the emptyBBX slots of the shelf currently being tested to insure thatall BBX 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 BBX slots are equipped. Edit the file asrequired to include BBX slots not currently equipped(per Systems Engineering documentation).IMPORTANT*3
Bay Level Offset Calibration – continuedDRAFTSCt4812T CDMA BTS Optimization/ATP Mar 20013-66BLO 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 BBXs 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 BBX slots. Slot 20contains the calibration data for the redundant BBX. Each BBX 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 BBX is organized as a large flat array.

Bay Level Offset Calibration – continuedMar 2001 3-69SCt4812T CDMA BTS Optimization/ATP DRAFTTX 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 BBX, 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 BBX (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 BBX 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 BBX 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 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:SBBXs are INS_TEST.SCable calibration has been performedSTX calibration has been performed and BLO has been downloaded forthe BTS.STest equipment has been connected correctly for a TX calibration.STest equipment has been selected and calibrated.Follow the procedure in Table 3-44 to calibrate the TX and RX antennapaths.Table 3-44: RFDS Calibration ProcedurenStep Action1Select the RFDS tab.2Select the RFDS menu.3Select the 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 TestingMar 2001 3-97SCt4812T CDMA BTS Optimization/ATP DRAFTAlarm 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 3-24). 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 3-25). 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
