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.!

Isolate the problem before proceeding.4Set the input power rocker switch P1 to the ON position.Repeat Step 3.Figure 2-7: DC Distribution Pre-test (COBRA RFDS Detail)NOTE:Set the input power switch ON while measuring theresistance from the DC power – with respect to thepower + terminal on the rear of the COBRA RFDS.INPUT POWERSWITCH (P1)FRONT OF COBRA RFDS(cut away view shown for clarity)RFDS REARINTERCONNECT PANEL“–” CONNECTORPIN“+” CONNECTORPINCONNECTOR (MADEUP OF A HOUSINGAND TWO PINS)FW001392
Initial Power–up TestsDRAFTSCt4812T CDMA BTS Optimization/ATP Mar 20012-12Power-up ProceduresPotentially lethal voltage and current levels are routed tothe BTS equipment. This test must be performed with asecond person present, acting in a safety role. Remove allrings, jewelry, and wrist watches prior to beginning thistest.WARNINGDC Input PowerIn the tests to follow, power will first be verified at the input to eachBTS frame. After power is verified, cards and modules within the frameitself will be powered up and verified one at a time.Before applying any power, verify the correct power feed and returncables are connected between the power supply breakers and the powerconnectors at the top of each BTS frame. Verify correct cable positionreferring to Figure 2-3 on page 2-7 for +27 V systems and Figure 2-5 onpage 2-9 for –48 V systems.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.CAUTIONFor 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*Motorola recommends that the DC input power cable used to connect theframe to the main DC power source conforms to the guidelines outlinedin Table 2-4. . . . continued on next page2

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.

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

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.
