Using the LMF Basic LMF Operation LMF Coverage in this Publication The LMF Application Program supports maintenance of both CDMA and SAS BTSs. All references to the LMF in this publication are to the CDMA portion of the program.. Operating Environments 3 The LMF Application Program allows the user to work in the two following Operating Environments that are accessed using the specified Desktop Icons.
Using the LMF – continued CDF/NECF Requirements For the LMF to recognize the devices installed in the BTS, a BTS CDF/NECF File that includes Equipage Information for all the devices in the BTS must be located in the applicable :\\cdma\bts–# folder. To provide the necessary Channel Assignment Data for BTS Operation, a CBSC CDF File that includes Channel Data for all BTS RF Modem Frames is also required in the folder..
Using the LMF – continued Understanding GUI Operation The following Screen Captures are provided to help understand how the GUI operates. For detailed information on performing these and other LMF Operations, refer to the LMF Help function on–line documentation. BTS Login Screen Figure 3-5 depicts the differences between Packet and Circuit CDMA “cdf” File Identification. Note that if there is a Packet Mode Version “bts” File, the “(P)” is added as a suffix.
Using the LMF – continued Self-Managed Network Elements Screen Figure 3-6 depicts the Self-Managed Network Elements (NEs) State of a Packet Mode SC4812T. Note that an “X” is on the front of each card that is under Self–Managed Network Elements (NEs) Control by the GLI3 Card.
Using the LMF – continued Packet Mode Commands Screen Figure 3-7 depicts three of the available Packet Mode Commands. Normally the GLI3 has Self-Managed Network Elements (NEs) Control of all cards as shown in Figure 3-6 by an “(X)”. In that state, the LMF may only status a single card. In order to download code or test a card, the LMF must request Self-Managed Network Elements (NEs) Control of the card by using the shown Pull–down Menu.
Using the LMF – continued Packet Mode Site under LMF Control Figure 3-8 depicts a Packet Mode Site that has the MCC–1 and the BBX–1 Cards under LMF Control. Notice that the “X” is missing from the front of these two cards.
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 Prerequisites Before attempting to log into a BTS, ensure that the following tasks have been completed: S The LMF Program is correctly installed on the LMF Computer. S A bts-nnn Folder with the correct CDF/NECF and CBSC Files is present. S The LMF Computer was connected to the BTS before starting the Windows Operating System and the LMF Software. If necessary, restart the computer after connecting it to the BTS in accordance with Table 3-6 and Figure 3-3.
Using the LMF – continued Table 3-10: BTS GUI Login Procedure n Step Action * IMPORTANT The following statements are provided to assist the operator in using the LMF GUI. S If an attempt is made to log into a BTS that is already logged on, all devices will appear gray in the display. S There may be instances where the BTS initiates a log out due to a system error (i.e., a device 3 failure).

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 Perform the procedure in Table 3-13 to logout of a BTS when using the CLI Environment. Table 3-13: BTS CLI Logout Procedure n Step Action NOTE 3 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 1. 1 Log out of a BTS by entering the following command: logout bts– – A system response similar to the following will be displayed: LMF> 13:24:51.

Bay Level Offset Calibration Introduction 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 that the correct Transmit Power is available at the BTS Antenna Connectors to meet site performance requirements. 3 What is BLO Calibration? Description BLO Calibration is the complete title of what is normally referred to as “Calibration.
Bay Level Offset Calibration – continued S Expansion Frame Diversity RX Path – The Starter Frame Main RX Signal is used for the Expansion Frame Diversity RX Signal. An Expansion Frame’s Diversity RX Path starts at ANTENNAS Connectors 1A, 2A, or 3A in the Starter Frame. It travels through the associated TRF or DRF, the MPC in SCCP Cage MPC–1 Slot, and the CIO Card where it is then routed out of the frame through the RX Expansion Out Connectors (RX EXPANSION 1A, 2A, or 3A).
Bay Level Offset Calibration – continued – TX Filter or TX Filter Combiner – TX Filter/Filter Combiner–to–DRF/TRF Cable – DRF or TRF 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 BBX Cards using the LMF BLO Download Function. A detailed description of the file organization and content is provided in the following paragraphs.
Bay Level Offset Calibration – continued S The first view of the array is shown in Table 3-37. This view shows the three branches of the array (Transmit, Main Receive, and Diversity Receive Offsets, and the Calibration Entry ranges that apply to each. Table 3-37: BLO bts–#.

Bay Level Offset Calibration – continued Example: C[1]=384 C[2]=19102 (Even Cal Entry) C[3]=777 (Odd Cal Entry) C[4]=19086 (Even Cal Entry) (Odd Cal Entry) = 1 “Calibration Point” = 1 “Calibration Point” . . . C[19]=777 3 (Odd Cal Entry) C[20]=19086 (Even Cal Entry) = 1 “Calibration Point” In the example above, BLO was measured at only two frequencies (Channels 384 and 777) for SCCP BBX–1 Slot Transmit (Table 3-38).
Bay Level Offset Calibration – continued Table 3-39: Set–up Test Equipment for RF Path Calibration Procedure n Step Action ! CAUTION To prevent damage to the Test Equipment, all Transmit (TX) Test Connections must be via the 30 dB Directional Coupler for 800 MHz or via a 30 dB Coupler with a 20 dB In–line Attenuator for 1900 MHz. 4 3 For TX Path Calibration, connect the Test Equipment as shown in Figure 3-16, Figure 3-17, or Figure 3-18, depending on the Communications Analyzer being used.
Bay Level Offset Calibration – continued Example: Measured Power Input (at TX Port) = 39.0 dBm Known BBX TX Power Output = –6.0 dBm BLO = (39.0) – (–6.0) = 45.0 dB Gain TX Calibration and the LMF The LMF Tests > TX > TX Calibration... and Tests > All Cal/Audit... Selections perform TX BLO Calibration Testing for installed BBX(s). – The All Cal/Audit... Selection initiates a series of actions to perform TX Calibration, and if Calibration is successful, download BLO and perform TX Audit.
Bay Level Offset Calibration – continued Primary BBX Cards normally will have BLOs in the lower half of the range. Using the example range, this would be from 40 to 45 dB. Checking the Single–Sided BLO Check Box should only be done when calibrating Primary BBX Cards because it will reduce the acceptable BLO Value variations to the lower half of the range.
Bay Level Offset Calibration – continued Test Pattern Channels and Gain Settings – The CDMA Channels and their respective Digital Gain Settings used for each Test Pattern are listed in Table 3-40.
Bay Level Offset Calibration – continued NOTE At new site installations, to facilitate the complete test of each SCCP Cage (if the cage is not already fully populated with BBX Cards), move BBX Cards from shelves currently not under test and install them into the empty BBX Slots of the shelf currently being tested to insure that all BBX TX Paths are tested. – This procedure can be bypassed on operational sites that are due for periodic Optimization.
