4812ET BTS Optimization/ATP — CDMA LMF Jan 2002 Notes 2 Preliminary Operations: Overview Jan 2002 2-1 SC
4812ET BTS Optimization/ATP — CDMA LMF Introduction This section first verifies proper frame equipage. This includes verifying module placement, jumper, and dual in–line package (DIP) switch settings against the site-specific documentation supplied for each BTS application. Next, pre-power up and initial power-up procedures are presented. Cellsite Types Sites are configured as with a maximum of 4 carriers, 3–sectored with a maximum of 4 carriers, and 6–sectored with a maximum of 2 carriers. Each type has unique characteristics and must be optimized accordingly. CDF The Cell-site Data File (CDF) contains site type and equipage data information and passes it directly to the LMF during optimization. The number of modem frames, C–CCP shelves, BBX and MCC boards (per cage), and linear power amplifier assignments are some of the equipage data included in the CDF. Site Equipage Verification Review the site documentation. Match the site engineering equipage data to the actual boards and modules shipped to the site. Physically inspect and verify the equipment provided for the BTS or Modem frame and ancillary equipment frame. Always wear a conductive, high impedance wrist strap while handling any circuit card/module to prevent damage by ESD. After removal, the card/module should be placed on a conductive surface or back into the anti–static bag it was shipped in. CAUTION Initial Installation of Boards/Modules Table 2-1: Initial Installation of Boards/Modules StepAction 1Refer to the site documentation and install all boards and modules into the appropriate shelves as required. Verify they are NOT SEATED at this time. 2As the actual site hardware is installed, record the serial number of each module on a “Serial Number Checklist” in the site logbook. 2 Preliminary Operations: Overview – continued SC

4812ET BTS Optimization/ATP — CDMA LMF Jan 2002 3-30 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. Table 3-13: Update Antenna Mapping Files StepAction ! CAUTION If you are not familiar with the UNIX vi editor, create a “dummy” CDF file, and practice making changes to it, prior to altering the “real” one. NOTE For more information on file management, creating bts directories, viewing/editing CDF files, refer to LMF Users Guide, Motorola part no. 68P09226A13. 1View the antenna.map file (see below) and verify the Xcvrs listed in the CDF file (and that are equipped in the BTS) are also listed in the antenna.map file (for both RX and TX tables). Make sure the antenna.map file has enough RX and TX antennas listed to cover the number of sectors indicated by CDF’s SiteConf parameter. Example of Antenna Map File R––– Rx ––– –– Sec –– ––––– Xcvrs ––––– R 1:M :RX1: 1 :1,4,5,8 R 2:D :RX2: 1 :1,4,5,8 R 3:M :RX3: 2 :2,4,6,8 R 4:D :RX4: 2 :2,4,6,8 R 5:M :RX5: 3 :3,4,7,8 R 6:D :RX6: 3 :3,4,7,8 T––– Tx ––– –– Sec –– ––––– Xcvrs ––––– T 1:0 :TX1: 1 :1,4 T 2:0 :TX2: 2 :2,4 T 3:0 :TX3: 3 :3,4 T 4:0 :TX4: 1 :5,8 T 5:0 :TX5: 2 :6,8 T 6:0 :TX6: 3 :7,8 2Verify all RX and TX antennas listed in the file antenna.map are also listed in the antenna.asu file. NOTE Make edits to the antenna.map and antenna.asu. files as required (using the vi editor). The The antenna.asu file is required only if the BTS is equipped with RFDS. Be sure that the information in antenna files matches your actual configuration. 3 Using CDMA LMF Jan 2002 3-31 SC
4812ET BTS Optimization/ATP — CDMA LMF Basic LMF Operation The terms “CDMA LMF” and “WinLMF” are interchangeable NOTE 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. The CLI environment provides additional capability to the user to perform manually controlled acceptance tests and audit the results of optimization and calibration actions. Basic operation of the LMF GUI includes the following: Selecting and deselecting BTS devices Enabling devices Disabling devices Resetting devices Obtaining device status Sorting a status report window For detailed information on performing these and other LMF operations, refer to the CDMA LMF Operator’s Guide, 68P64114A78. Basic LMF Operation . 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. When the CLI is launched after the GUI, the CLI automatically finds and uses an in–progress login session with a BTS initiated under the GUI. This allows the use of the GUI and the CLI in the same BTS login session. If a CLI handler is already running when the GUI is launched (this happens if the CLI window is already running when the user starts the GUI, or if another copy of the GUI is already running when the user starts the GUI), a dialog window displays the following 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? Thi s window also contains yes and no buttons. Selecting yes starts the application. Selecting no terminates the application. 3 Using CDMA LMF – continued SC
4812ET BTS Optimization/ATP — CDMA LMF Jan 2002 3-32 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 –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. measure bbx–<bts_id>–<bbx_id> rssi channel=6 sector=5 Refer to the LMF CLI Commands (68P09251A59) for a complete explanation of the CLI commands and their usage. Logging into a BTS Be sure that the correct bts–#.cdf and cbsc–#.cdf file is used for the BTS. These should be the CDF files that are provided for the BTS by the CBSC. Failure to use the correct CDF files can result in wrong results. Failure to use the correct CDF files to log into a live (traffic carrying) site can shut down the site. IMPORTANT * Logging into a BTS establishes a communications link between the BTS and the CDMA LMF. You may be logged into one or more BTS’s at a time, but only one LMF may be logged into each BTS. Before attempting to log into the BTS, confirm the CDMA LMF is properly connected to the BTS (see Figure 3-4). Follow the procedure in Table 3-14 to log into a BTS. Prerequisites Before attempting to login to a BTS, ensure the following have been completed: The LMF is correctly installed and prepared. A bts-nnn folder with the correct CDF and CBSC file exists. The LMF is correctly installed and prepared, and the LMF computer was connected to the BTS before starting the Windows operating system and LMF software. If necessary, restart the computer after connecting it to the BTS (see Table 3-6 and Figure 3-4). 3 Using CDMA LMF – continued Jan 2002 3-33 SC
