BTS Sector Configuration 1 68P09258A31–A BTS Sector Configuration There are a number of ways to configure the BTS frame. Table 1-5 outlines the basic requirements. When carrier capacity is greater than two, a 2:1 or 4:1 cavity combiner must be used. For one or two carriers, bandpass filters or cavity combiners may be used, depending on sectorization and channel sequencing.

Preliminary Operations: Overview 68P09258A31–A Preliminary Operations: Overview 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.
Preliminary Operations: Overview 68P09258A31–A Initial Installation of Boards/Modules Follow the procedure in Table 2-1 to verify the initial installation of boards/modules. Table 2-1: Initial Installation of Boards/Modules Step 1 2 Action Refer to the site documentation and install all boards and modules into the appropriate shelves as required. Verify they are NOT SEATED at this time.
Preliminary Operations: Overview 68P09258A31–A Setting Frame C–CCP Shelf Configuration Switch The backplane switch settings behind the fan module nearest the breaker panel should be set as shown in Figure 2-2. The switch setting must be verified and set before power is applied to the BTS equipment.
Pre–Power–up Tests 68P09258A31–A Pre–Power–up Tests Objective This procedure checks for any electrical short circuits and verifies the operation and tolerances of the cellsite and BTS power supply units prior to applying power for the first time. Test Equipment The following test equipment is required to complete the pre–power–up tests: S Digital Multimeter (DMM) CAUTION Always wear a conductive, high impedance wrist strap while handling the any circuit card/module to prevent damage by ESD.
Pre–Power–up Tests 68P09258A31–A DC Power Pre-test (BTS Frame) Before applying any power to the BTS frame, follow the procedure in Table 2-2 while referring to Figure 2-3 and Figure 2-4 for +27 V systems or to Figure 2-5 and Figure 2-6 for –48 V systems to verify there are no shorts in the BTS frame DC distribution system. 2 Table 2-2: DC Power Pre–test (BTS Frame) Step Action 1 Physically verify that all DC power sources supplying power to the frame are OFF or disabled.
Pre–Power–up Tests 68P09258A31–A Table 2-2: DC Power Pre–test (BTS Frame) Step Action 8 In the –48 V BTS, insert and lock the DC/DC LPA converter modules into their associated slots one at a time. Repeat Step 3 after inserting each module. S A typical response is that the ohmmeter steadily climbs in resistance as capacitors charge, finally indicating approximately 500 Ω.

Pre–Power–up Tests 68P09258A31–A DC Power Pre-test (RFDS) Before applying power to the RFDS, follow the steps in Table 2-3, while referring to Figure 2-7, to verify there are no shorts in the RFDS DC distribution system, backplanes, or modules/boards. As of the date of this publication, the RFDS is not used with the –48 V BTS. 2 NOTE Visual inspection of card placement and equipage for each frame vs.
Initial Power–up Tests and Procedures 68P09258A31–A Initial Power–up Tests and Procedures Power-up Procedures WARNING Potentially lethal voltage and current levels are routed to the BTS equipment. This test must be performed with a second person present, acting in a safety role. Remove all rings, jewelry, and wrist watches prior to beginning this test. DC Input Power In the tests to follow, power will first be verified at the input to each BTS frame.
Initial Power–up Tests and Procedures 68P09258A31–A Common Power Supply Verification The procedure in Table 2-5 must be performed on any BTS frame connected to a common power supply at the site after the common power supply has been installed and verified per the power supply OEM suggested procedures. 2 Perform the following steps to verify the power input is within specification before powering up the individual cards/modules with the frames themselves.
Initial Power–up Tests and Procedures 68P09258A31–A Initial Power-up (RFDS) The procedure in Table 2-6 must be performed on the RFDS after input power from the common power supply has been verified. Perform the following steps to apply initial power to the cards/modules within the frame itself, verifying that each is operating within specification. NOTE Visual inspection of card placement and equipage for each frame vs.
Initial Power–up Tests and Procedures 68P09258A31–A Table 2-7: Initial Power–up (BTS) Step 7 2 Action Set the LPA breakers to the ON position (per configuration) by pushing them IN one at a time. See Figure 1-13 on page 1-32 or Figure 1-14 on page 1-33 for configurations and Figure 2-3 on page 2-8 or Figure 2-5 on page 2-10 for LPA breaker panel layout.

3 Chapter 3 Optimization/Calibration Oct 2003 1X SCt 4812T BTS Optimization/ATP 3-1
Introduction to Optimization and Calibration 68P09258A31–A Introduction to Optimization and Calibration Overview This section describes procedures for isolating the BTS from the span lines, preparing and using the LMF, downloading system operating software, CSM reference verification/optimization, set up and calibration of the supported test equipment, transmit/receive path verification, using the RFDS, and verifying the customer defined alarms and relay contacts are functioning properly.
Introduction to Optimization and Calibration 68P09258A31–A 11. If the TX calibration fails, repeat the full optimization for any failed paths. 12. If the TX calibration fails again, troubleshoot and correct the problem that caused the failure and repeat the full optimization for the failed path. 13.
Introduction to Optimization and Calibration NOTE 68P09258A31–A Refer to Figure 3-1 and the LMF Help function on–line documentation for additional information on the layout of the LMF 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 LMF computer terminal. BTSs configured for Circuit Backhaul use bts.
Preparing the LMF 68P09258A31–A 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 LMF. 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 68P09258A31–A LMF Features and Installation Requirements Before optimization can be performed, the LMF application software must be installed and configured on a computer platform meeting Motorola–specified requirements (see Recommended Test Equipment and Software in Chapter 1). NOTE 3 For the CDMA LMF graphics to display properly, the computer platform must be configured to display more than 256 colors.
Preparing the LMF 68P09258A31–A LMF File Structure Overview The LMF uses a :\ folder that contains all of the essential data for installing and maintaining the BTS. The following list outlines the folder structure for LMF. Except for the bts-nnn folders, these folders are created as part of the LMF installation. Refer to the CDMA LMF Operator’s Guide for a complete description of the folder structure. Figure 3-1: LMF Folder Structure (C:) 3 x:\ folder cdma folde
Preparing the LMF 68P09258A31–A LMF Home Directory The LMF installation program creates the default home directory, c:\wlmf, and installs the application files and subdirectories (folders) in it. Because this can be changed at installation, the CDMA LMF home directory will be referred to with the generic convention of: :\ Where: = the LMF computer drive letter where the CDMA LMF home directory is located.
Preparing the LMF 68P09258A31–A 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#.xml Where: * = any characters can be substituted there # = the actual integer BTS number 3 The NECB and its corresponding NECJ must have the exact same name, except for the “B” and “J” difference after the initial NEC characters. The NECB and the NECJ must reside in the \cdma\bts
