Preliminary Operations: Overview Introduction This section first verifies proper frame equipage against the site-specific documentation supplied for each BTS application. Cicruit Backhaul Operation If circuit backhaul operation is being used, perform the procedures described in this chapter. Refer to the LMF Help, if further information is needed. Packet Backhaul Operation If packet backhaul configuration is being used, perform the procedures described in Appendix I.
Preliminary Operations: Overview S Effective Rate Power (ERP) table for all TX channels to antennas respectively. Motorola System Engineering specifies the ERP of a transmit antenna based on the site geography, antenna placement, and government regulations. Working from this ERP requirement, the antenna gain, (dependent on the units of measurement specified) and antenna feed line loss can be combined to determine the required power of the BTS.
Ethernet LAN Ethernet LAN Termination For proper operation, the BTS Ethernet Local Area Network (LAN) connections must be terminated with a 50–ohm loads. This is done by placing four (4) 50–ohm BNC terminations on the LAN A and B external IN and OUT connectors located on the rear of the BTS. This is only done on stand–alone BTSs. The front panel LAN connections are not terminated with loads. Verify that the LAN A and B external IN and OUT connectors at the rear of the BTS have terminations installed.
Introduction to Optimization and Calibration Overview This section describes procedures for isolating the BTS from the span lines, preparing and using the WinLMF, downloading system operating software, CSA reference verification/optimization, set up and calibration of the supported test equipment, and transmit/receive paths are functioning properly. NOTE Before using the WinLMF, use an editor to view the “CAVEATS” section in the “readme.txt” file in the c:\wlmf folder for any applicable information.
Introduction to Optimization and Calibration – continued 10. If the TX calibration fails again, troubleshoot and correct the problem causing the failure, and repeat the full optimization for the failed path. 11. If the TX calibration and audit portion of the full optimization passes for a path but some of the TX or RX tests fail, troubleshoot and correct the problem causing the failure, and run the individual tests as required until all TX and RX tests have passed for all paths.
Introduction to Optimization and Calibration – continued NOTE Refer to Figure 6-2 and the WinLMF Help function on–line documentation for additional information on the layout of the WinLMF directory structure (including CDF/NECF file locations and formats). BTS System Software Download BTS system software must be successfully downloaded to the BTS processor boards before optimization can be performed. BTS operating code is loaded from the WinLMF computer terminal.
Preparing the LMF Overview of Packet BTS files R16.0 and earlier releases had the configuration file called CDF for each BTS and CBSC used by WinLMF. In 16.1 Packet BTS, BTS with GLI3 booting in packet binary, the CDF is replaced by two new configuration files called Network Element Configuration Base (NECB) and Network Element Change Journal (NECJ).
Preparing the LMF – continued WinLMF Features and Installation Requirements Before optimization can be performed, the WinLMF application software must be installed and configured on a computer platform meeting Motorola–specified requirements. NOTE For the WinLMF graphics to display properly, the computer platform must be configured to display more than 256 colors. See the operating system software instructions for verifying and configuring the display settings.
Preparing the LMF – continued FTP Server Port in use On some Windows 2000 installations, a process called “inetd.exe” makes the FTP server port 21 unusable by the WinLMF. If the WinLMF reports that the FTP server could not start because the port is in use, make sure the inetd.exe is not running by using the Task Manager’s process list. If inetd.exe is running, end the process by selecting it and clicking the “End Process” button. Inetd32.exe is NOT the same and ending it will not resolve this problem.
Preparing the LMF – continued :\ Where: = the WinLMF computer drive letter where the CDMA WinLMF home directory is located. = the directory path or name where the CDMA WinLMF is installed. NECF Filename Conventions and Directory Location NECF The NECF actually consists of two files: the NECB and NECJ. The naming convention for the NECB and NECJ is: NECB*bts#.xml NECJ*bts#.
Preparing the LMF – continued WinLMF Operating System Installation This section provides information and instructions for installing and updating the WinLMF software and files.
Preparing the LMF – continued Copy BTS CDF (or NECF) and CBSC CDF Files to the WinLMF Computer Before logging on to a BTS with the WinLMF computer to execute optimization/ATP procedures, the correct bts-#.cdf (or bts–#.necf) and cbsc-#.cdf files must be obtained from the CBSC and put in a bts-# folder in the WinLMF computer. This requires creating versions of the CBSC CDF files on a DOS–formatted floppy diskette and using the diskette to install the CDF files on the WinLMF computer.
Preparing the LMF – continued Table 6-3: Copying CDF or NECF Files to the WinLMF Computer n Step 4 Action Type mount and press the Enter key. NOTE S Look for the “floppy/no_name” message on the last line displayed. S If the eject command was previously entered, floppy/no_name will be appended with a number.

Preparing the LMF – continued Creating a Named HyperTerminal Connection for MMI Communication Confirming or changing the configuration data of certain BTS Field Replaceable Units (FRU) requires establishing an MMI communication session between the WinLMF and the FRU. Using features of the Windows operating system, the connection properties for an MMI session can be saved on the WinLMF computer as a named Windows HyperTerminal connection.
Preparing the LMF – continued Table 6-4: Create HyperTerminal Connection Step 5 Action In the Port Settings tab of the COM# Properties window displayed, configure the RS–232 port settings as follows: S S S S S Bits per second: 9600 Data bits: 8 Parity: None Stop bits: 1 Flow control: None 6 Click OK. 7 Save the defined connection by selecting: File > Save 8 Close the HyperTerminal window by selecting: File > Exit 9 Click the Yes button to disconnect when prompted.
Span Lines – Interface and Isolation T1/E1 Span Interface NOTE At active sites, the OMC–R/CBSC must disable the BTS and place it out–of–service (OOS). DO NOT remove the span line cable connectors until the OMC–R/CBSC has disabled the BTS. Before connecting the WinLMF computer to the BTS LAN, the OMC–R/CBSC must disable the BTS and place it OOS. This will allow the WinLMF to control the BTS, and prevent the CBSC from inadvertently sending control information to the BTS during WinLMF–based tests.
LMF to BTS Connection Connect the WinLMF to the BTS The WinLMF computer may be connected to the LAN A or B connector located on the front panel or at the rear of the BTS. Figure 6-3 below shows the general location of these connectors. LAN A is considered the primary LAN.

Using the LMF – continued Command Line Interface Overview The LMF also provides Command Line Interface (CLI) capability. Activate the CLI by clicking on a shortcut icon on the desktop. The CLI can 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 one handler can be running at one time. The architectural design is such that the GUI must be started before the CLI if you want the GUI and CLI to use the same handler.
Using the LMF – continued Logging Into a BTS Logging into a BTS establishes a communication link between the BTS and the LMF. An LMF session can be logged into only one BTS at a time. Prerequisites Before attempting to log into a BTS, ensure the following have been completed: S The LMF is correctly installed on the LMF computer. S A bts-nnn folder with the correct CDF/NECF and CBSC files exists.

Using the LMF – continued BTS Login from the CLI Environment Follow the procedures in Table 6-8 to log into a BTS when using the CLI environment. NOTE If the CLI and GUI environments are to be used at the same time, the GUI must be started first and BTS login must be performed from the GUI. Refer to Table 6-7 to start the GUI environment and log into a BTS. Table 6-8: BTS CLI Login Procedure n Step 1 Action Double–click the WinLMF CLI desktop icon (if the LMF CLI environment is not already running).
Using the LMF – continued Logging Out Logging out of a BTS is accomplished differently for the GUI and CLI operating environments. NOTE The GUI and CLI environments use the same connection to a BTS. If a GUI and the CLI session are running for the same BTS at the same time, logging out of the BTS in either environment will log out of it for both. When either a login or logout is performed in the CLI window, there is no GUI indication that the login or logout has occurred.
Using the LMF – continued Logging Out of a BTS from the CLI Environment Follow the procedure in Table 6-10 to logout of a BTS when using the CLI environment. Table 6-10: BTS CLI Logout Procedure n Step Action NOTE If the BTS is also logged into from a GUI running at the same time and further work must be done with it in the GUI, proceed to Step 2. 1 Log out of a BTS by entering the following command: logout bts– A response similar to the following will be displayed: LMF> 13:24:51.

Pinging the Processors Pinging the BTS For proper operation, the integrity of the Ethernet LAN A and B links must be verified. Figure 6-10 represents a typical BTS Ethernet configuration. The drawing depicts cabling and termination for both the A and B LANs. Ping is a program that sends request data packets to hosts on a network, in this case GLI modules on the BTS LAN, to obtain a response from the “target” host specified by an IP address.
Pinging the Processors NOTE The Ethernet LAN A and B cables and/or terminations must be installed on each frame/enclosure external LAN connector before performing this test. All other processor board LAN connections are made through the backplanes. Table 6-12: Pinging the Processors Step Action 1 If this is a first–time communication with a newly–installed frame or a GLI card which has been replaced, perform the procedure in Table 11-3 and then return to step 2.
Pinging the Processors Table 6-12: Pinging the Processors Step Action 14 If ping was unsuccessful after restarting the LMF computer, press the GLI front panel reset pushbutton and perform steps 7 through 10 again. 15 After the BTS has been successfully pinged, be sure the 50Ω termination was replaced on the BTS LAN B IN connector at the rear of the BTS. Disconnect the LMF cable from the front LAN A connector, and connect it to front LAN B (right–hand connector).
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 RAM code can be downloaded to a device that is in any state. After the download is started, the device being loaded will change to OOS_ROM (blue). When the download is completed successfully, the device will change to OOS_RAM (yellow). When code is downloaded to a GLI, the LMF automatically also downloads data and then enables the GLI. When enabled, the GLI will change to INS_ACT (bright green). For non–GLI devices, data must be downloaded after RAM code is downloaded.
Download the BTS – continued Verify GLI ROM Code Loads Devices should not be loaded with a RAM code version which is not compatible with the ROM code with which they are loaded. Before downloading RAM code and data to the processor cards, follow the procedure in Table 6-13 to verify the GLI devices are loaded with the correct ROM code for the software release used by the Base Station System.
Download the BTS – continued Download RAM Code and Data to GLI Prerequisites S Prior to performing these procedures, ensure a code file exists for each of the devices to be loaded. S The LMF computer is connected to the BTS (refer to Table 6-6), and is logged in using the GUI environment (refer to Table 6-7). Procedure Follow the procedure in Table 6-14 to download the firmware application code for GLI. The download code action downloads data and also enables the GLI.
Download the BTS – continued NOTE CSA devices are RAM code–loaded at the factory. RAM code is downloaded to CSA only if a newer software version needs to be loaded. When downloading to multiple devices, the download may fail for some of the devices (a time–out occurs). These devices can be loaded individually after completing the multiple download. Follow the steps in Table 6-15 to download RAM code and data to non–GLI devices.

Test Set Calibration Background Proper test equipment calibration helps to ensure accurate BTS optimization and acceptance testing by assuring that the test equipment and associated cables do not introduce measurement errors. NOTE If the test equipment set being used to optimize or test the BTS has been calibrated and maintained as a set, this procedure does not need to be performed. This procedure must be performed prior to beginning the optimization.
Test Set Calibration – continued Manual Agilent E4406A Transmitter Tester – The E4406A does not support the power level zeroing calibration performed by the WinLMF. If this instrument is to be used for Bay Level Offset calibration and calibration is attempted with the WinLMF Calibrate Test Equipment function, the WinLMF will return a status window failure message stating that zeroing power is not supported by the E4406A.
Test Set Calibration – continued Selecting Test Equipment Test equipment may be selected either manually with operator input or automatically using the WinLMF autodetect feature. Manually Selecting Test Equipment in a Serial Connection Tab Test equipment can be manually specified before or after the test equipment is connected. The WinLMF does not attempt to verify the test equipment is actually detected when manual selection is specified.
Test Set Calibration – continued Automatically Selecting Test Equipment in the Serial Connection Tab When using the auto-detection feature to select test equipment, the WinLMF determines which test equipment items are actually communicating with WinLMF.

Bay Level Offset Calibration Purpose of Bay Level Offset Calibration Bay Level Offset (BLO) calibration is the central activity of the optimization process. BLO calibration compensates for normal equipment variations within the BTS RF paths and assures the correct transmit power is available at the BTS antenna connectors to meet site performance requirements. What is BLO Calibration? Description BLO calibration is the complete title of what is normally referred to as “calibration.
Bay Level Offset Calibration – continued BLO Calibration Data File During the calibration process, the LMF creates a calibration (CAL) data file where BLO values are stored. After calibration has been completed, these offset values must be downloaded to the BBXs using the LMF BLO download function. A detailed description of the file organization and content is provided in the following paragraphs NOTE Due to the size of the file, Motorola recommends printing out a copy of a bts–#.
Bay Level Offset Calibration – continued CAL File and BLO Data Download When BLO data is downloaded to the BBXs after calibration, the data is downloaded to the devices in the order it is stored in the CAL file. TX calibration data (entries C[1] – C[60]) are sent first. Data for the ten BBX slot 1 calibration points (entries C[1] – C[20]) are sent initially, followed by data for the ten BBX slot 2 calibration points (entries C[21] – C[40]), and so on.
Bay Level Offset Calibration – continued Transmit (TX) Path Calibration Description The assigned channel frequency and desired power level at the frame TX ports for transmit calibration are derived from the BTS CDF file. Each BBX at the site is assigned to a carrier. These are specified respectively in the carrier field of the ParentCARRIER parameter in each BBXs CDF file block.
