Pinging the Processors 68P09255A69-3 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 3-16: 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 6-3 and then return to step 2.
Pinging the Processors 68P09255A69-3 Table 3-16: Pinging the Processors Step 14 Action If ping was unsuccessful after restarting the LMF computer, press the MGLI front panel reset pushbutton and perform steps 7 through 10 again. NOTE Refer to Table 6-1 if ping was unsuccessful after resetting the MGLI. 15 After the BTS has been successfully pinged, be sure the 50Ω termination was replaced on the BTS frame LAN B IN connector in the power entry compartment (Figure 3-8).
Download the BTS 68P09255A69-3 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 68P09255A69-3 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 68P09255A69-3 Table 3-17: Verify GLI ROM Code Loads Step Action 4a - Log out of the BTS as described in Table 3-13 or Table 3-14, as applicable. 4b - Disconnect the LMF computer. 4c - Reconnect the span lines as described in Table 5-7. 4d - Have the CBSC download the correct ROM code version to the BTS devices.
Download the BTS 68P09255A69-3 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. NOTE 3 - CSM devices are RAM code-loaded at the factory. RAM code is downloaded to CSMs 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).

Download the BTS 68P09255A69-3 Enable MCCs This procedure configures the MCC and sets the “tx fine adjust” parameter. The “tx fine adjust” parameter is not a transmit gain setting, but a timing adjustment that compensates for the processing delay in the BTS (approximately 3 mS). Follow the steps outlined in Table 3-22 to enable the MCCs installed in the SCCP shelves. NOTE The MGLI and CSM must be downloaded and enabled, prior to downloading and enabling an MCC.
CSM System Time - GPS & LFR/HSO Verification 68P09255A69-3 CSM System Time - GPS & LFR/HSO Verification Clock Synchronization Manager (CSM) Sub-system Description Overview - Each BTS CSM sub-system features two CSM boards per RFMF. The primary function of the CSM cards is to maintain CDMA system time. GPS is used as the primary timing reference and synchronizes the entire cellular system. In typical operation, the primary CSM locks its Digital Phase Locked Loop (DPLL) circuits to GPS signals.
CSM System Time - GPS & LFR/HSO Verification 68P09255A69-3 Timing Source Fault Management - Fault management has the capability of switching between the GPS synchronization source and the LFR/HSO backup source in the event of a GPS receiver failure. During normal operation, the card in slot CSM 1 selects GPS as the primary timing source (Table 3-24). The source selection can also be overridden via the LMF or by the system software.
CSM System Time - GPS & LFR/HSO Verification 68P09255A69-3 CSM Frequency Verification The objective of this procedure is the initial verification of the Clock Synchronization Module (CSM) cards before performing the RF path verification tests.

Test Set Calibration 68P09255A69-3 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 (see the Terms and Abbreviations section of Chapter 1) being used to optimize or test the BTS has been calibrated and maintained as a set, this procedure does not need to be performed.
Test Set Calibration 68P09255A69-3 Power Meters - Manual power meter calibration procedures to be performed prior to automated calibration are included in the Equipment Calibration section of Appendix F. Cable Calibration - Manual cable calibration procedures using the HP 8921A and Advantest R3465 communications system analyzers are provided in the Manual Cable Calibration section of Appendix F, if needed. GPIB Addresses GPIB addresses can range from 1 through 30.
Test Set Calibration 68P09255A69-3 Manually Selecting Test Equipment in a Serial Connection Tab Test equipment can be manually specified before or after the test equipment is connected. The LMF does not attempt to verify the test equipment is actually detected when manual selection is specified. Follow the procedure in Table 3-28 to manually select test equipment.
Test Set Calibration 68P09255A69-3 Automatically Selecting Test Equipment in the Serial Connection Tab When using the auto-detection feature to select test equipment, the LMF determines which test equipment items are actually communicating with LMF. Follow the procedure in Table 3-29 to use the auto-detection feature. Table 3-29: Selecting Test Equipment Using Auto-Detect Step 3 Action 1 In the LMF window menu bar, click Tools and select Options... from the pull-down menu.
Test Set Calibration 68P09255A69-3 Calibrating Test Equipment The LMF Calibrate Test Equipment function zeros the power measurement level of the test equipment item that is to be used for TX calibration and audit. If both a power meter and an analyzer are connected (for example, an HP 437 and an HP8921A/600), only the power meter is zeroed. NOTE The Agilent E4406A transmitter tester does not support power measurement level zeroing.
Test Set Calibration 68P09255A69-3 2. Measure the loss of the short cable plus the RX test cable configuration. The RX test cable configuration normally consists only of a coax cable with type-N connectors that is long enough to reach from the BTS RX connector to the test equipment. When the BTS antenna connectors carry duplexed TX and RX signals, a directional coupler and, if required by BTS type, an additional attenuator are also required for the RX test cable configuration.
Test Set Calibration 68P09255A69-3 Table 3-31: Test Cable Configuration Calibration with a Communications System Analyzer Step 2 Action Enter one or more channel numbers in the Channels box. NOTE Multiple channel numbers must be separated by a comma with no spaces (for example, 200,800). When two or more channel numbers are entered, the cables will be calibrated for each channel. Interpolation will be accomplished for other channels, as required, for TX calibration.

It is not part of the final test setup. After calibration is completed, do not re-arrange any cables.
Test Set Calibration 68P09255A69-3 Setting Cable Loss Values Cable loss values for TX and RX test cable configurations are normally set by accomplishing automatic cable calibration using the LMF and the applicable test equipment. The LMF stores the measured loss values in the cable loss files. The cable loss values can also be set or changed manually. CAUTION If cable calibration was performed without using the LMF, cable loss values must be manually entered in the LMF database.
Test Set Calibration 68P09255A69-3 Setting TX Coupler Loss Value If an in-service TX coupler is installed, the coupler loss must be manually entered so it will be included in the LMF TX calibration and audit calculations. Prerequisites LMF is logged into the BTS Path loss, in dB, of the TX coupler must be known Table 3-35: Setting TX Coupler Loss Values Step 3 Action 1 Click Util in the BTS menu bar, and select Edit > Coupler Loss... in the pull-down menus.
Bay Level Offset Calibration 68P09255A69-3 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.
