Preparing the LMF – continued Update Antenna Mapping Files Earlier release versions may require the antenna.map file to be updated. There are two antenna mapping files. These are antenna.map and antenna.asu . Follow the steps outlined in Table 3-13 to check the antenna mapping file and update as needed.
Using CDMA LMF Basic LMF Operation NOTE The terms “CDMA LMF” and “WinLMF” are interchangeable 3 The CDMA LMF allows the user to work in the two following operating environments which are accessed using the specified desktop icon: Graphical User Interface (GUI) using the WinLMF icon Command Line Interface (CLI) using the WinLMF CLI icon The GUI is the primary optimization and acceptance testing operating environment.
Using CDMA LMF – continued CLI Format Conventions The CLI command can be broken down in the following way: Verb Device including device identifier parameters Switch Option parameters consisting of: – Keywords 3 – Equals sign (=) between the keyword and the parameter value – Parameter values Spaces are required between the verb, device, switch, and option parameters. A hyphen is required between the device and its identifiers. Following is an example of a CLI command.
Using CDMA LMF – continued BTS Login from the GUI Environment Follow the procedures in Table 3-14 to log into a BTS when using the GUI environment Table 3-14: BTS GUI Login Procedure Step 1 Action Start the LMF GUI environment by double clicking on the WinLMF desktop icon (if the LMF’s not running). 3 NOTE If a warning similar to the following is displayed, select No, shut down other LMF sessions which may be running, and start the LMF GUI environment again: The CLI handler is already running.
Using CDMA LMF – continued Table 3-14: BTS GUI Login Procedure Step 10 Action Click on Login. (A BTS tab with the BTS is displayed.) NOTE If you attempt to log in to a BTS that is already logged on, all devices will be gray. There may be instances where the BTS initiates a log out due to a system error (i.e., a device failure). 3 If the MGLI is OOS_ROM (blue), it will have to be downloaded with code before other devices can be seen.
Using CDMA LMF – continued BTS Login from the CLI Environment Follow the procedures in Table 3-15 to log into a BTS when using the GUI environment Table 3-15: BTS CLI Login Procedure Step 1 Action 3 Double click the WinLMF CLI desktop icon (if the LMF CLI environment is not already running). NOTE If a BTS was logged into under a GUI session when the CLI environment was started, the CLI session will be logged into the same BTS, and step 2 is not required.
Using CDMA LMF – continued Table 3-16: BTS GUI Logout Procedure Step 3 Action Click on Yes or press the Enter key to confirm logout. You are returned to the Login tab. NOTE If a logout was previously performed on the BTS from a CLI window running at the same time as the GUI, a Logout Error popup message will appear stating the system should not log out of the BTS. When this occurs, the GUI must be exited and restarted before it can be used for further operations.
Using CDMA LMF – continued Establishing an MMI Communication Session For those procedures that require MMI communications between the LMF and BTS FRUs, follow the procedure in Table 3-18 to initiate the communication session. Table 3-18: Establishing MMI Communications Step Action 3 1 Connect the LMF computer to the equipment as detailed in the applicable procedure that requires MMI communication session.
Download the BTS Overview Before a BTS can operate, each equipped device must contain device initialization (ROM) code. ROM code is loaded in all devices during manufacture, factory repair, or, for software upgrades, from the CBSC using the DownLoad Manager (DLM). Device application (RAM) code and data must be downloaded to each equipped device by the user before the BTS can be made fully functional for the site where it is installed.
Download the BTS – continued When code is downloaded to an MGLI or GLI, the LMF automatically also downloads data and then enables the MGLI. When enabled, the MGLI will change to INS_ACT (bright green). A redundant GLI will not be automatically enabled and will remain OOS_RAM (yellow). When the redundant GLI is manually commanded to enable through the LMF, it will change state to INS_SBY (olive green). For non–GLI devices, data must be downloaded after RAM code is downloaded.
Download the BTS – continued Table 3-19: Verify GLI ROM Code Loads Step 3 Action 3 In the status report window which opens, note the number in the ROM Ver column for each GLI2. 4 If the ROM code loaded in the GLIs is not the correct one for the software release being used on the BSS, log out of the BTS, disconnect the LMF computer, reconnect the span lines as described in Table 5-6, and have the CBSC download the correct ROM code version to the BTS devices.
Download the BTS – continued Table 3-20: Download and Enable MGLI and GLI Devices Step Action 5 Once the MGLI is enabled, load and enable additional installed GLIs by clicking on the devices and repeating steps 3 and 4. 6 Click OK to close the status window for the additional GLI devices. 3 Download RAM Code and Data to Non–GLI Devices Downloads to non–GLI devices can be performed individually for each device or all installed devices can be downloaded with one action.
Download the BTS – continued Table 3-21: Download RAM Code and Data to Non–GLI Devices Step 5 6 3 Action Click Device in the BTS menu bar, and select select Download > Data in the pull–down menus. – A status report is displayed showing the results of the download for each selected device. Click OK to close the status report window when downloading is completed. Select CSM Clock Source A CSM can one of have three different clock sources.
Download the BTS – continued on–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 and synchronizes the entire cellular system. CSM 2 provides redundancy (but does not have a GPS receiver). The BTS may be equipped with a LORAN–C LFR, HSO, or external 10 MHz Rubidium source which the CSM can use as a secondary timing reference. The HSOX is used for expansion frames.
Download the BTS – continued Table 3-23: Enable CSMs Step Action NOTE 2 3 If equipped with two CSMs, CSM–1 should be bright green (INS–ACT) and CSM–2 should be dark green (INS–STY) If more than an hour has passed, refer to CSM Verification, see Figure 3-8 and Table 3-26 to determine the cause. NOTE After the CSMs have been successfully enabled, observe the PWR/ALM LEDs are steady green (alternating green/red indicates the card is in an alarm state).
CSM System Time – GPS & LFR/HSO Verification Clock Synchronization Manager System Time The primary function of the Clock Synchronization Manager (CSM) boards (slots 1 and 2) is to maintain CDMA system time. The CSM in slot 1 is the primary timing source while slot 2 provides redundancy. The CSM2 card (CSM second generation) is required when using the remote GPS receiver (R–GPS). R–GPS uses a GPS receiver in the antenna head that has a digital output to the CSM2 card.
CSM System Time – GPS & LFR/HSO Verification – continued The HSO is a high stability 10 MHz oscillator with the necessary interface to the CSMs. The HSO is typically installed in those geographical areas not covered by the LORAN–C system. Since the HSO is a free–standing oscillator, system time can only be maintained for 24 hours after 24 hours of GPS lock. Upgrades and Expansions: LFR2/HSO2/HSOX LFR2/HSO2 (second generation cards) both export a timing signal to the expansion frames.
CSM System Time – GPS & LFR/HSO Verification – continued CSM Frequency Verification The objective of this procedure is the initial verification of the CSM boards before performing the RF path verification tests. Parts of this procedure will be repeated for final verification after the overall optimization has been completed.

Bay Level Offset Calibration Introduction Calibration compensates for normal equipment variations within the BTS and assures maximum measurement accuracy. RF Path Bay Level Offset Calibration Calibration identifies the accumulated gain in every transmit path (BBX slot) at the BTS site and stores that value in the CAL file. The BLOs are subsequently downloaded to each BBX. Each receive path starts at a BTS RX antenna port and terminates at a backplane BBX slot.
Bay Level Offset Calibration – continued TX Path Calibration The TX Path Calibration assures correct site installation, cabling, and the first order functionality of all installed equipment. The proper function of each RF path is verified during calibration. The external test equipment is used to validate/calibrate the TX paths of the BTS. WARNING Before installing any test equipment directly to any TX OUT connector you must first verify that there are no CDMA channels keyed.
Bay Level Offset Calibration – continued BLO Calibration Data File During the calibration process, the LMF creates a calibration (BLO) data file. After calibration has been completed, this offset data must be downloaded to the BBXs using the Download BLO function. An explanation of the file is shown below. NOTE Due to the size of the file, Motorola recommends that you print out a hard copy of a bts.cal file and refer to it for the following descriptions.
Bay Level Offset Calibration – continued – The second breakdown of the array is per sector. Three sectors are allowed. Table 3-39: BTS.
Bay Level Offset Calibration – continued The 20 calibration entries for each slot/branch combination must be stored in order of increasing frequency. If less than 10 points (frequencies) are calibrated, the largest frequency that is calibrated is repeated to fill out the 10 points. Example: C[1]=384, odd cal entry = 1 ‘‘calibration point” C[2]=19102, even cal entry C[3]=777, C[4]=19086, . .
Bay Level Offset Calibration – continued Transmit (TX) Path Calibration The assigned channel frequency and power level (as measured at the top of the frame) for transmit calibration is derived from the site CDF file. For each BBX, the channel frequency is specified in the ChannelList CDF file parameter and the power is specified in the SIFPilotPwr CDF file parameter for the sector associated with the BBX (located under the ParentSECTOR field of the ParentCARRIER CDF file parameter).
Bay Level Offset Calibration – continued CDF – This pattern setting is for advanced users who need to use CDF gain settings for all channels included in the Standard pattern setting (pilot, paging, synch, and six traffic). Using this pattern setting requires the selection of both a BBX and at least one MCC. Verify BLO In both the TX Calibration and All Cal/Audit dialog boxes, a Verify BLO checkbox is provided and checked by default.
Bay Level Offset Calibration – continued IMPORTANT * 3 Verify all BBX boards removed and repositioned have been returned to their assigned shelves/slots.

Bay Level Offset Calibration – continued Calibration Audit Introduction The BLO calibration audit procedure confirms the successful generation and storage of the BLO calibrations. The calibration audit procedure measures the path gain or loss of every BBX transmit path at the site. In this test, actual system tolerances are used to determine the success or failure of a test. The same external test equipment set up is used.
Bay Level Offset Calibration – continued TX Audit Test The Tests menu item, TX Audit, performs the TX BLO Audit test for a BBX(s). All measurements are made through the appropriate TX output connector using the calibrated TX cable setup. Prerequisites Before running this test, the following should be done: CSM–1,GLI2s, BBXs have correct code load. 3 Primary CSM and MGLI2 are INS. All BBXs are OOS_RAM.
