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. 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.
Preliminary Operations: Overview – continued Setting Frame C–CCP Shelf Configuration Switch If the frame is a Starter BTS, the backplane switch settings behind the fan module nearest the breaker panel should be set to the ON position (see Figure 2-1). 2 The switch setting must be verified and set before power is applied to the BTS equipment.
Power Cabinet Initial Power Up Introduction This section of the manual contains instructional information on the proper power up procedure for the SC 4812ET BTS. Also presented in this chapter is the Optimization/ATP tests to be preformed on the Power cabinet. Please pay attention to all Cautions and Warning statements in order to prevent accidental injury to personnel. The following tools are used in the Power Cabinet Power Up procedures.
Power Cabinet Initial Power Up – continued Table 2-2: AC Voltage Measurements Step 2 Action 3 Measure the AC voltage from terminal L1 to ground. This voltage should be in the range of nominally 115 to 120 V AC. 4 Measure the AC voltage from terminal L2 to neutral. This voltage should be in the range of nominally 115 to 120 V AC. 5 Measure the AC voltage from terminal L2 to ground. This voltage should be in the range of nominally 115 to 120 V AC.
Power Cabinet Initial Power Up – continued Power Up Tests Table 2-3 lists the step–by–step instructions for Power Up Tests. 2 Table 2-3: Power Up Tests Step Action 1 Probe the output voltage test point on the DMAC while pressing the 25° C set button on the TCP. The voltage should read 27.4 + 0.2 VDC. Adjust Master Voltage on DMAC if necessary. Release the TCP 25° C set button. 2 Depending on the ambient temperature, the voltage reading may now change by up to + 1.
Power Cabinet Initial Power Up – continued Table 2-4: Battery Charge Test 2 Step Action 4 The bargraph meters on the rectifier modules can be used as a rough estimate of the total battery charge current. Each rectifier module has eight (8) LEDs to represent the output current. Each illuminated LED indicates that approximately 12.5% (1/8 or 8.75 Amps) of the rectifiers maximum (70 Amps) current is flowing.
Power Cabinet Initial Power Up – continued Table 2-5: RF Cabinet Power Up Step Action 4 Measure the voltage drop between the Power Cabinet meter test point and the 27 V buss bar inside the RF Cabinet PDA while the RF Cabinet is transmitting. 2 NOTE For a three (3) sector carrier system, the voltage drop should be less than 0.2 VDC. For a twelve (12) sector carrier system, the voltage drop should be less than 0.3 VDC.
Power Cabinet Initial Power Up – continued Alarm Verification The alarms test should be performed at a convenient point in the RF Cabinet ATP procedure, since an LMF is necessary to ensure that the RF Cabinet is receiving the appropriate alarms from the Power Cabinet. 2 The SC 4812ET is capable of concurrently monitoring 10 customer defined input signals and four customer defined outputs, which interface to the 50–pin punchblock. All alarms are defaulted to “Not Equipped” during ATP testing.
Power Cabinet Initial Power Up – continued Table 2-8: Heat Exchanger Alarm Step Action 1 Turn circuit breaker “B” of the Heat Exchanger circuit breakers OFF. This will generate a Heat Exchanger alarm, ensure that the LMF reports the correct alarm condition in the RF Cabinet. 2 Alarm condition will be reported as BTS Relay 25 – contact alarm. 3 Turn the circuit breaker “B” ON. Ensure that the alarm condition is now removed. 2 NOTE The Heat Exchanger will go through the Start Up sequence.
Power Cabinet Initial Power Up – continued Table 2-11: Minor Alarm Step 2 Action 1 Turn the TCP power switch OFF. This will generate a minor alarm. Verify that the minor alarm LED (amber) is illuminated on the DMAC and the LMF reports this minor alarm. 2 Alarm condition will be reported as BTS–24 contact. 3 Turn the TCP power switch ON. The alarm condition should clear. Rectifier Alarms The following series of tests are for single rectifier modules in a multiple rectifier system.
Power Cabinet Initial Power Up – continued Table 2-13: Multiple Rectifier Failure or Major Alarm Step Action 3 Verify that the LMF reports both alarm conditions. Alarm condition will be reported as BTS–29 and BTS–21 contacts respectively. 4 Turn the AC breaker for the 1st shelf ON. Verify that all alarms have cleared. 5 Return the rectifier module to its original location. This completes the alarm test on the Power Cabinet.
Power Cabinet Initial Power Up – continued Table 2-15: Multiple Rectifier Failure or Major Alarm Step 2 Action 4 Turn the AC breaker for this shelf ON. Verify that all alarms have cleared. 5 Return all rectifier module to their original location. This completes the rectifier alarm tests on the Power Cabinet. Battery Over Temperature Alarm (Optional ONLY) CAUTION Use special care to avoid damaging insulation on cables, or damaging battery cases when using a power heat gun.
Power Cabinet Initial Power Up – continued Rectifier Over Temperature Alarm 2 NOTE This is the J8 on the rear of the DMAC itself, this is not connector J8 on the connector bulkhead at the rear of the cabinet. Table 2-16 gives instructions on testing the battery over temperature alarm system. Table 2-17: Rectifier Over Temperature Alarm Step 1 Action Remove the J8 link on the rear of the DMAC.
Pre–Power–up Tests Objective 2 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: 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 – continued DC Power Pre-test (BTS Frame) Before applying any power to the BTS cabinet, follow the steps outlined in Table 2-18 while referring to Figure 2-2 to verify there are no shorts in the RF or Power Cabinet’s DC distribution system. Table 2-18: DC Power Pre–test (RF Cabinet and Power Cabinet) Step Action 1 Physically verify that all DC/DC converters supplying power to the cabinets are OFF or disabled.
Pre–Power–up Tests – continued Table 2-18: DC Power Pre–test (RF Cabinet and Power Cabinet) Step 2 7 Action Set the 8 LPA breakers ON by pushing them IN one at a time. Repeat step 3 after turning on each breaker. A typical response is that the ohmmeter will steadily climb in resistance as capacitors charge, stopping at approximately 500 Ω.. 8 Plug all LPAs and EBA fan module into associated plugs in the chassis one at a time. Repeat step 3 after connecting each LPA and EBA fan module.

Optimization/Calibration – Introduction Introduction This section describes procedures for downloading system operating software, set up of the supported test equipment, CSM reference verification/optimization, and transmit/receive path verification. Cell–site Types Sites are configured as Omni/Omni or Sector/Sector (TX/RX). Each type has unique characteristics and must be optimized accordingly.
Optimization/Calibration – Introduction – continued 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. Before you can log into a site, the LMF must have a BTS folder for that site. Whenever there is a new release of BTS system software (binaries), it must first be loaded on the LMF from a CD–ROM before it can be downloaded to the BTS.
Isolate Span Lines/Connect LMF Isolate BTS from T1/E1 Spans IMPORTANT * – At active sites, the OMC/CBSC must disable the BTS and place it out of service (OOS). DO NOT remove the span surge protectors until the OMC/CBSC has disabled the BTS!

Bay Level Offset Calibration Introduction Calibration compensates for normal equipment variations within the BTS and assures maximum measurement accuracy. RF Path Bay Level Offset Calibration Calibration identifies the accumulated gain in every transmit path (BBX2 slot) at the BTS site and stores that value in the CAL file. The BLOs are subsequently downloaded to each BBX2. Each receive path starts at a BTS RX antenna port and terminates at a backplane BBX2 slot.
Bay Level Offset Calibration – continued TX Path Calibration The TX Path Calibration assures correct site installation, cabling, and the first order functionality of all installed equipment. The proper function of each RF path is verified during calibration. The external test equipment is used to validate/calibrate the TX paths of the BTS. WARNING Before installing any test equipment directly to any TX OUT connector you must first verify that there are no CDMA channels keyed.
Bay Level Offset Calibration – continued BLO Calibration Data File During the calibration process, the LMF creates a calibration (BLO) data file. After calibration has been completed, this offset data must be downloaded to the BBX2s using the Download BLO function. An explanation of the file is shown below. NOTE Due to the size of the file, Motorola recommends that you print out a hard copy of a bts.cal file and refer to it for the following descriptions.
Bay Level Offset Calibration – continued – The second breakdown of the array is per sector. Three sectors are allowed. Table 3-34: BTS.

Bay Level Offset Calibration – continued Transmit (TX) Path Calibration The assigned channel frequency and power level (as measured at the top of the frame) for transmit calibration is derived from the site CDF file. For each BBX2, the channel frequency is specified in the ChannelList CDF file parameter and the power is specified in the SIFPilotPwr CDF file parameter for the sector associated with the BBX2 (located under the ParentSECTOR field of the ParentCARRIER CDF file parameter).
Bay Level Offset Calibration – continued IMPORTANT * Verify all BBX2 boards removed and repositioned have been returned to their assigned shelves/slots. Any BBX2 boards moved since they were downloaded will have to be downloaded again. Exception Handling 3 In the event of a failure, the calibration procedure displays a FAIL message in the status report window and provides information in the Description field. Recheck the test setup and connection and re–run the test.
Bay Level Offset Calibration – continued Transmit (TX) Path Audit Perform the calibration audit of the TX paths of all equipped BBX2 slots, per the steps in Table 3-38. WARNING Before installing any test equipment directly to any TX OUT connector, first verify there are no CDMA BBX2 channels keyed. Failure to do so can result in serious personal injury and/or equipment damage.
Bay Level Offset Calibration – continued TX Audit Test The Tests menu item, TX Audit, performs the TX BLO Audit test for a BBX2(s). All measurements are made through the appropriate TX output connector using the calibrated TX cable setup. Prerequisites: Before running this test, the following should be done: CSM–1,GLI2s, BBX2s have correct code load. Primary CSM and MGLI2 are INS. 3 All BBX2s are OOS_RAM. Test equipment and test cables are calibrated and connected for TX BLO calibration.
Bay Level Offset Calibration – continued All Cal/Audit test The Tests menu item, All Cal/Audit, performs the TX BLO Calibration and Audit test for a XCVR(s). All measurements are made through the appropriate TX output connector using the calibrated TX cable setup. NOTE If the TX calibration portion of the test passed, the BLO data will automatically be downloaded to the BBX2(s) before the audit portion of the test is run.
Bay Level Offset Calibration – continued Create CAL File The Create Cal File function gets the BLO data from BBXs and creates/updates the CAL file for the BTS. If a CAL file does not exist a new one is created. If a CAL file already exists it is updated. After a BTS has been fully optimized a copy of the CAL file must exist so it can be transferred to the CBSC. If TX calibration has been successfully performed for all BBXs and BLO data has been downloaded, a CAL file will exist.

CDMA Operating Frequency Programming Information – North American PCS Bands Introduction Programming of each of the BTS BBX2 synthesizers is performed by the BTS GLIs via the CHI bus. This programming data determines the transmit and receive transceiver operating frequencies (channels) for each BBX2. PCS Channels Figure D-1 shows the valid channels for the North American PCS frequency spectrum.
CDMA Operating Frequency Programming Information – North American Bands – continued Calculating Center Frequencies Table D-1 shows selected CDMA candidate operating channels, listed in both decimal and hexadecimal, and the corresponding transmit, and receive frequencies. Center frequency for channels not shown in the table may be calculated as follows: Direction Formula Example TX 1930 + (0.05 * Channel#) Channel 262: 1930 + (0.05*262) = 1943.10 RX 1850 + (0.05 * Channel#) Channel 237: 1850 + (0.

Appendix E: PN Offset Programming Information – continued IMPORTANT * If the wrong I and Q values are used with the wrong FineTxAdj parameter, system timing problems will occur. This will cause the energy transmitted to be “smeared” over several Walsh codes (instead of the single Walsh code that it was assigned to), causing erratic operation. Evidence of smearing is usually identified by Walsh channels not at correct levels or present when not selected in the Code Domain Power Test.
