FCC Part 68
FCC Part 68 Requirements
This equipment complies with Part 68 of the Federal Communications Commission (FCC) Rules and regulations. A label inside the cabinet frame easily visible with the door open in the upper portion of the cabinet contains, among other information, the FCC Registration Number and Ringer Equivalence Number (REN) for this equipment. If requested, this information must be provided to the telephone company.
The REN is useful to determine the quantity of the devices which may connect to the telephone line. Excessive RENs on the telephone line may result in the devices not ringing in response to incoming calls. In most, but not all areas, the sum of the RENs should not exceed five (5.0). To be certain of the number of devices that may be connected to the line as determined by the total RENs, contact the telephone company to determine the maximum REN for the calling area.
If the dial–in site access modem causes harm to the telephone network, the telephone company will notify you in advance that temporary discontinuance of service may be required. If advance notice is not practical, the telephone company will notify you of the discontinuance as soon as possible. Also, you will be advised of your right to file a complaint with the FCC if you believe it is necessary.
The telephone company may make changes in its facilities, equipment, operations, or procedures that could affect the operation of your dial–in site access modem. If this happens, the telephone company will provide advance notice so that you can modify your equipment as required to maintain uninterrupted service.
If you experience trouble with the dial–in site access modem, please contact:
Motorola Cellular Service Center (MCSC) 1501 W. Shure Drive Arlington Heights, Illinois 60004 Phone Number: (847) 632–5390
for repair and/or warranty information. If the trouble is causing harm to the telephone network, the telephone company may request you to disconnect the equipment from the network until the problem is solved. You should not attempt to repair this equipment yourself. This equipment contains no customer or user–serviceable parts.
Changes or modifications not expressly approved by Motorola could void your authority to operate this equipment.

Why Optimize?
What Is Optimization?
Proper optimization and calibration assures:
Accurate downlink RF power levels are transmitted from the site.Accurate uplink signal strength determinations are made by the site.
Optimization compensates for the site-specific cabling and normal equipment variations. Cables that interconnect the BTS and Duplexer assemblies (if used), for example, are cut and installed at the time of the BTS frame installation at the site. Site optimization guarantees that the combined losses of the new cables and the gain/loss characteristics and built-in tolerances of each BTS frame do not accumulate, causing improper site operation.
Optimization identifies the accumulated loss (or gain) for all receive and transmit paths at the BTS site, and stores that value in a database.
The RX path starts at the ancillary equipment frame RFDS RX
directional coupler antenna feedline port, through the RX input port on the rear of the frame, through the DDRCs, Multicoupler Preselector Card (MPC), and additional splitter circuitry, ending at a CDMA Channel Processor (C–CCP) backplane Broad Band Transceiver (BBX) slot in the C–CCP shelf.
A transmit path starts at the BBX, through the C–CCP backplane slot,
travels through the LPA/Combiner TX Filter and ends at the rear of the input/output (I/O) Panel. If the RFDS option is added, then the TX path continues and ends at the top of the RFDS TX directional coupler antenna feedline port installed in the ancillary equipment frame.

Optimization Overview – continued
These values are factored in by the BTS equipment internally, leaving only site specific antenna feed line loss and antenna gain characteristics to be factored in by the CFE when determining site Effective Radiated Power (ERP) output power requirements.
Each C–CCP shelf BBX board is optimized to a specific RX and TX antenna port. (One BBX board acts in a redundant capacity for BBXs 1–12, and is optimized to all antenna ports). A single value is generated for each path, thereby eliminating the accumulation of error that would occur from individually measuring and summing the gain and loss of each element in the path.
When to Optimize
New Installations
After the initial site installation, the BTS must be prepared for operation. This preparation includes verifying hardware installation, initial power up, and GPS verification. Basic alarm tests are also addressed.
A calibration audit of all RF transmit paths is performed to verify factory calibration.
1
A series of ATP CDMA verification tests are covered using the actual equipment set up. An ATP is also required before the site can be placed in service.
Site Expansion
Optimization is also required after expansion of a site.
Periodic Optimization
Periodic optimization of a site may also be required, depending on the requirements of the overall system.
Repaired Sites
Verify repair(s) made to the BTS by consulting an Optimization/ATP Test Matrix table. This table outlines the specific tests that must be performed anytime a BTS subassembly or RF cable associated with it is replaced.
IMPORTANT

Required Test Equipment
To ensure consistent, reliable, and repeatable optimization test results, test equipment meeting the following technical criteria should be used to optimize the BTS equipment. You can, of course, substitute test equipment with other test equipment models supported by the LMF meeting the same technical specifications.
NOTE
During manual testing, you can substitute test equipment with other test equipment models not supported by the LMF, but those models must meet the same technical
specifications.
The customer has the responsibility of accounting for any measurement variances and/or additional losses/inaccuracies that can be introduced as a result of these substitutions. Before beginning optimization or
troubleshooting, make sure that the test equipment needed is on hand and operating properly.
Test Equipment Calibration
Test Cable Calibration
Equipment Warm–up
Optimum system performance and capacity depend on regular equipment service, calibration, and characterization prior to BTS optimization. Follow the original equipment manufacturer (OEM) recommended maintenance and calibration schedules closely.
Equipment test cables are very important in optimization. Motorola recommends that the cable calibration be run at every BTS with the test cables attached. This method compensates for test cable insertion loss within the test equipment itself. No other allowance for test cable insertion loss needs to be made during the performance of tests.
Another method is to account for the loss by entering it into the LMF during the optimization procedure. This method requires accurate test cable characterization in a shop. The cable should be tagged with the characterization information prior to field optimization.
After arriving at the a site, the test equipment should be plugged in and turned on to allow warm up and stabilization to occur for as long as possible. The following pieces of test equipment must be warmed–up for a minimum of 60 minutes prior to using for BTS optimization or RFDS calibration procedures.

BTS Equipment Identification
Equipment Overview
The SC 4812ET BTS consists of an RF Cabinet that is an outdoor, weatherized version of the SC 4812T. The RF cabinet is powered by 27 Vdc and each cabinet has the capability to support up to 4 carriers (at 3 sector) or 2 carriers (at 6 sector).
The RF Cabinet houses the fan modules, C–CCP, LPA modules, LPA trunking backplane, Bandpass 2:1 & 4:1 Combiners, Duplexer/Receive Filter/Directional Couplers (DRDC) and a DC Power distribution assembly. The Power Cabinet (PC) provides +27 Vdc distribution and battery backup for the SC 4812ET. The Power Cabinet houses batteries, battery heaters, rectifiers, an AC Load Center (ACLC), a power distribution assembly, and two duplexed GFCI convenience outlets.
Logical BTS
A logical BTS can consist of up to four SC 4812ET frames. When the LMF is connected to frame 1 of a logical BTS, you can access all devices in all of the frames that make up the logical BTS. A logical BTS CDF file that includes equippage information for all of the logical BTS frames and their devices is required. A Centralized Base Station Controller (CBSC) file that includes channel data for all of the logical BTS fames is also required.
1
The first frame of a logical BTS has a –1 suffix (e.g., BTS–812–1) and other frames of the logical BTS are numbered with suffixes, –101, –201, and –301 (e. g. BTS–812–201). When you log into a BTS a FRAME tab is displayed for each frame. If there is only one frame for the BTS, there will only be one tab (e.g., FRAME–282–1) for BTS–282. If a logical BTS has more than one frame, there will be a separate FRAME tab for each frame (e.g. FRAME–438–1, FRAME–438–101, and FRAME–438–202 for a BTS–438 that has all three frames). If an RFDS is included in the CDF file, an RFDS tab (e.g., RFDS–438–1) will be displayed.
Actions (e.g., ATP tests) can be initiated for selected devices in one or more frames of a logical BTS. Refer to the Select devices help screen for information on how to select devices.
C–CCP Shelf Card/Module Device ID Numbers
All cards/modules/boards in the frames at a single site, assigned to a single BTS number, are also identified with unique Device ID numbers dependent upon the Frame ID number in which they are located. Refer to Table 1-3 and Table 1-4 for specific C–CCP Shelf Device ID numbers.

Site Equipage Verification
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.
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.
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, BBX2 and MCC24E/MCC8E boards (per cage), and linear power amplifier assignments are some of the equipage data included in the CDF.
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.

CAUTION
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.
Initial Installation of Boards/Modules
Table 2-1: Initial Installation of Boards/Modules

Initial Power Up
Introduction
Required Tools
Cabling Inspection
The following information is used to check for any electrical short circuits and to verify the operation and tolerances of the cellsite and BTS power supply units before applying power for the first time. It contains instructional information on the initial proper power up procedures for the SC 4812ET power cabinet and RF cabinet. Also presented are 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 procedures.
DC current clamp (600 Amp capability with jaw size to accommodate
2/0 cable).
Hot Air Gun – (optional for part of the Alarm Verification)Digital Multimeter (DMM)
Using the site-specific documentation generated by Motorola Systems Engineering, verify that the following cable systems are properly connected:
Receive RF cabling – up to 12 RX cablesTransmit RF cabling – up to six TX cables

IMPORTANT
*
For positive power applications (+27 V):
The positive power cable is red.The negative power cable is black. (The black power
cable is at ground potential.)
Initial Inspection and Setup
CAUTION
Ensure all battery breakers for unused battery positions are open (pulled out) during any part of the power up process, and remain in the off position when leaving the site.
Table 2-2: Initial Inspection and Setup
Step Action
1 Verify that ALL AC and DC breakers are turned OFF in both the Power and RF cabinets. Verify that
the DC power cables between the Power and RF cabinets are connected with the correct polarity
2 The RED cables connect to the uppermost three (3) terminals (marked +) in both cabinets. Confirm
that the split phase 240/120 AC supply is correctly connected to the AC load center input.

Power Up Sequence
The first task in the power up sequence is to apply AC power to the Power cabinet. Once power is applied a series of AC Voltage measurements is required.
Table 2-3: AC Voltage Measurements
Step Action
1 Measure the AC voltages connected to the AC load center (access the terminals from the rear of the
cabinet after removing the AC load center rear panel). See Figure 2-2.
2 Measure the AC voltage from terminal L1 to neutral. This voltage should be in the range of nominally
115 to 120 V AC.
surge protection module inside the AC load center.
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.
6 Measure L1 – L2 – should be from 208 to 240 V AC.
CAUTION
If the AC voltages are in excess of 120 V (or exceed 200 V) when measuring between terminals L1 or L2 to neutral or ground, STOP and Do Not proceed until the cause of the higher voltages are determined. The power cabinet WILL be damaged if the Main breaker is turned on with excessive voltage on the inputs.

Table 2-4: Applying AC Power
Step Action
1 When the input voltages are verified as correct, turn the Main AC breaker (located on the front of the
AC Load Center) ON. Observe that all eight (8) green LEDs on the front of the AC Load Center are illuminated (see Figure 2-7).
2 Turn Rectifier 1 and Rectifier 2 AC branch breakers (on the AC Load Center) ON. All the installed
rectifier modules (see Figure 2-7) will start up and should each have two green LEDs (DC and Power) illuminated.
3 Turn the Meter Alarm Panel module, ON (see Figure 2-3), while observing the K2 contact in the
PDA assembly (see Figure 2-9). The contact should close. The Meter Alarm Panel voltage meter should read approximately 27.4 +
0.2 Vdc.
4 Turn the Temperature Compensation Panel (TCP) ON, (see Figure 2-4). Verify that the Meter Alarm
Control Panel does not have any alarm LEDs illuminated.
5 Check the rectifier current bargraph displays (green LED display on the rectifier module). None
should be illuminated at this point.
NOTE
If batteries are fitted, turn on the two battery heater AC breakers on the AC Load Center.

Table 2-5 lists the step–by–step instructions for Power Up Tests.
Table 2-5: Power Cabinet Power Up Tests
Step Action
1 Probe the output voltage test point on the Meter Alarm Panel while pressing the 25° C set button on
the TCP (see Figure 2-4). The voltage should read 27.4 +
0.2 Vdc. Adjust Master Voltage on Meter
Alarm Panel if necessary. Release the TCP 25° C set button.
2 Depending on the ambient temperature, the voltage reading may now change by up to + 1.5 V
compared to the reading just measured. If it is cooler than 25C, the voltage will be higher, and if it is
warmer than 25C, the voltage will be lower. 3 Ensure the RF cabinet 400 Amp main DC breaker is OFF. 4 Close the three (3) Main DC breakers on the Power Cabinet ONLY. Close by holding in the reset
button on the front of the PDA, and engaging one breaker at a time. 5 Measure the voltage between the + and – terminals at the rear of the Power Cabinet and the RF
Cabinet, observing that the polarity is correct. The voltage should be the same as the measurement in
step 2. 6 Place the probes across the black and red battery buss bars in each battery compartment. Place the
probe at the bottom of the buss bars where the cables are connected. The DC voltage should measure
the same as the previous step.

DC Power Pre-test (BTS Frame)
Before applying any power to the BTS cabinet, verify there are no shorts in the RF or power DC distribution system (see Figure 2-5).
Table 2-6: DC Power Pre–test (BTS Frame)
Step Action
1 Physically verify that all AC rectifiers supplying power to the RF cabinets are OFF or disabled (see
Figure 2-5). There should be no 27 Vdc on DC feed terminals.
2 On each RF cabinet:
Unseat all circuit boards/ modules in the distribution shelf, transceiver shelf, and Single Carrier
Linear Power Amplifier (SCLPA) shelves, but leave them in their associated slots.
Unseat all circuit boards (except CCD and CIO cards) in the C–CCP shelf and LPA shelves, but
leave them in their associated slots.
Set C–CCP shelf breakers to the OFF position by pulling out power distribution breakers (labeled
C–CCP 1, 2, 3 – located on the power distribution panel).
Set LPA breakers to the OFF position by pulling out power distribution breakers (8 breakers,
labeled 1A–1B through 4C–4D located on the power distribution panel).

6 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.
NOTE
For a three (3) sector carrier system, the voltage drop should be less than 0.2 V.
For a twelve (12) sector carrier system, the voltage drop should be less than 0.3 V. 7 Using a DC current probe, measure the current in each of the six (6) DC cables that are connected
between the RF and Power Cabinet. The DC current measured should be approximately the same. If
there is a wide variation between one cable and the others (>20 A), check the tightness of the
connections (torque settings) at each end of the cable.

Battery Charge Test (Connected Batteries)
2
Table 2-8: Battery Charge Test (Connected Batteries)
Step Action
1 Close the battery compartment breakers for connected batteries ONLY. This process should be
completed quickly to avoid individual battery strings with excess charge current
Table 2-8 lists the step–by–step instructions for testing the batteries.
NOTE
If the batteries are sufficiently discharged, the battery circuit breakers may not engage individually
due to the surge current. If this condition is observed, turn off the Meter Alarm Panel power switch,
and then engage all the connected battery circuit breakers, the Meter Alarm Panel power switch
should then be turned ON. 2 Using the DC current probe, measure the current in each of the battery string connections to the buss
bars in each battery cabinet. The charge current may initially be high but should quickly reduce in a
few minutes if the batteries have a typical new battery charge level. 3 The current in each string should be approximately equal (+ 5 A). 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 A) of the rectifiers maximum (70 A)
current is flowing.
EXAMPLE:
Question: A system fitted with three (3) rectifier modules each have three bargraph LEDs
illuminated. What is the total output current into the batteries?
Answer: Each bargraph is approximately indicating 12.5% of 70 A, therefore, 3 X 8.75 equals
26.25 A. As there are three rectifiers, the total charge current is equal to (3 X 26.25 A) 78.75 A.
This charge current calculation only applies at this part of the start up procedure, when the RF Cabinet
is not powered on, and the power cabinet heat exchanger is turned off. 5 Allow a few minutes to ensure that the battery charge current stabilizes before taking any further
action. Recheck the battery current in each string. If the batteries had a reasonable charge, the current
in each string should reduce to less than 5 A. 6 Recheck the DC output voltage. It should remain the same as measured in step 4 of the Power Up
Test.
NOTE
If discharged batteries are installed, all bargraphs may be illuminated on the rectifiers during the
charge test. This indicates that the rectifiers are at full capacity and are rapidly charging the batteries.
It is recommended in this case that the batteries are allowed to charge and stabilize as in the above
step before commissioning the site. This could take several hours.
Battery Discharge Test
Perform the test procedure in Table 2-9 only when the battery current is less than 5 A per string. Refer to Table 2-8 on the procedures for checking current levels.

Table 2-9: Battery Discharge Test
Step Action
1 Turn the battery test switch on the Meter Alarm Panel, ON (see Figure 2-3). The rectifier output
voltage and current should decrease by approximately 10% as the batteries assume the load. Alarms
for the Meter Alarm Panel may occur. 2 Measure the individual battery string current using the DC current probe. The battery discharge
current in each string should be approximately the same (within + 3 Turn Battery Test Switch OFF.

Optimization/Calibration – Introduction
Introduction
This chapter provides procedures for downloading system operating software, set up of the supported test equipment, CSM reference verification/optimization, and transmit/receive path verification.
IMPORTANT
Optimization Process
*
After a BTS is physically installed and the preliminary operations (power up) have been completed, the CDMA LMF is used to calibrate and optimize the BTS. The basic optimization process can be accomplished as follows:
Before using the LMF, use an editor to view the CAVEATS section in the readme.txt file in the c:\wlmf folder for any applicable information.
Download MGLI2–1 with code and data and then enable MGLI2–1.Use the status function and verify that all of the installed devices of
the following types respond with status information: CSM2, BBX2, GLI2, and MCC (and TSU if RFDS is installed). If a device is installed and powered up but is not responding and is colored gray in the BTS display, the device is not listed in the CDF file. The CDF file will have to be corrected before the device can be accessed by CDMA LMF.
Download code and data to all devices of the following types:
CSM2BBXGLI2 (other than MGLI21)MCC
3
Apr 2001
Download the RFDS TSIC (if installed).Verify the operation of the GPS and HSO signals.Enable the following devices (in the order listed):
Secondary CSM (slot 2)Primary CSM (slot 1)All MCCs
Connect the required test equipment for a full optimization.Select the test equipment.Calibrate the TX and RX test cables if they have not previously been
calibrated using the CDMA LMF that is going to be used for the optimization/calibration. The cable calibration values can also be entered manually.

Optimization/Calibration – Introduction – continued
Select all of the BBXs and all of the MCCs and use the full
optimization function. The full optimization function performs TX calibration, BLO download, TX audit, all TX tests, and all RX tests for all selected devices.
If the TX calibration fails, repeat the full optimization for any failed
paths.
If the TX calibration fails again, correct the problem that caused the
failure and repeat the full optimization for the failed path.
3
Cell–site Types
Cell–site Data File
If the TX calibration and audit portion of the full optimization passes
for a path but some of the TX or RX tests fail, correct the problem that caused the failure and run the individual tests as required until all TX and RX tests have passed for all paths.
Sites are configured as Omni/Omni or Sector/Sector (TX/RX). Each type has unique characteristics and must be optimized accordingly.
The CDF includes the following information:
Download instructions and protocolSite specific equipage informationC–CCP shelf allocation plan
BBX2 equipage (based on cellsite type) including redundancyCSM equipage including redundancyMCC (MCC24E, MCC8E or MCC1X) channel element allocation
plan. This plan indicates how the C–CCP shelf is configured, and how the paging, synchronization, traffic, and access channel elements (and associated gain values) are assigned among the (up to
12) MCCs in the shelf.
CSM equipage including redundancyEffective Rated Power (ERP) table for all TX channels to antennas
respectively. Motorola System Engineering specifies the ERP of a transmit antenna based on site geography, antenna placement, and government regulations. Working from this ERP requirement, the antenna gain, (dependent on the units of measurement specified) and antenna feed line loss can be combined to determine the required power at the top of the BTS frame. The corresponding BBX2 output level required to achieve that power level on any channel/sector can also be determined.

NOTE
Refer to the CDMA LMF Operators Guide, 68P64114A78, for additional information on the layout of the LMF directory structure (including CDF file locations and formats).

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.
IMPORTANT
Site Equipage Verification
*
The CDF is normally obtained from the CBSC on a DOS formatted diskette, or through a file transfer protocol (ftp) if the LMF computer has ftp capability. Refer to the CDMA LMF Operators Guide, 68P64114A78, or the LMF Help screen, for more information.
If you have not already done so, use an editor to view the CDF, and review the site documentation. Verify the site engineering equipage data in the CDF to the actual site hardware.
Before using the LMF for optimization/ATP, the correct bts#.cdf and cbsc#.cdf files for the BTS must be obtained from the CBSC and put in a bts–# folder in the LMF. Failure to use the correct CDF files can cause wrong results. Failure to use the correct CDF files to log into a live (traffic carrying) site can shut down the site.
CAUTION
Always wear a conductive, high impedance wrist strap while handling any circuit card/module to prevent damage by ESD. Extreme care should be taken during the removal and installation of any card/module. After removal, the card/module should be placed on a conductive surface or back into the anti–static bag in which it was shipped.

Configure Channel Service Unit
Each frame is equipped with one 50–pair punch block for spans, customer alarms, remote GPS, and power cabinet alarms. See Figure 3-2 and refer to Table 3-1 for the physical location and pin call–out information. To disable the span, pull the surge protectors for the respective span.
Before connecting the LMF to the frame LAN, the OMC/CBSC must disable the BTS and place it OOS to allow the LMF to control the CDMA BTS. This prevents the CBSC from inadvertently sending control information to the CDMA BTS during LMF based tests.
The M–PATH 537 Channel Service Unit (CSU) provides in–band SNMP–managed digital service access to T1 and fractional T1 lines. M–PATH units plug into the ADC Kentrox 2–slot frame (see Figure 3-1).
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.
Remote M–PATH management is available via SNMP over an in–band data link on the T1 line (using a facility data link or 8–64 Kbps of a DS0 channel). The unit at the near end of the management path can be an SNMP manager or another M–PATH CSU.
Each 19 inch rack can support two CSU M–PATH 537 modules. Each M–PATH 537 module supports one and only one span connection.
Programming of the M–PATH is accomplished through the DCE 9–pin connector on the front panel of the CSU shelf. Manuals and a Microsoft Windows programming disk is supplied with each unit.

Setting the Control Port
Whichever control port is chosen, it must first be set up so the control port switches match the communication parameters being used by the control device. If using the rear–panel DTE control port, set the shelf–address switch SA5 to “up” (leave the switch down for the rear–panel DCE control port).
For more information, refer to the Kentrox Installation Guide, manual number 65–77538001 which is provided with each CSU.
Plug one of the cables listed below into the Control Port connectors:
Part Number Description of Cable
01–95006–022 (six feet) DB–9S to DB–9P 01–95010–022 (ten feet) The control port cables can be used to connect the shelf to:

* IMPORTANT
First Time Installations:
– Install U/WIN (First) – Install Java Runtime Environment (Second) – Install LMF Software (Third) – Install BTS Binaries (Fourth) – Install/Create BTS Folders (Fifth)
Any time you install U/WIN, you must install the LMF software because the installation of the LMF modifies some of the files that are installed during the U/Win installation. Installing U/Win over–writes these modifications.
NOTE
There are multiple binary image packages for installation on the CD–ROM. When prompted, choose the load that corresponds to the switch release that you currently have installed. Perform the Device Images install after the WinLMF installation.
If applicable, a separate CD ROM of BTS Binaries may be available for binary updates.

CDMA LMF Home Directory
The CDMA 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:
<x>:\<lmf home directory>
Where: <x> = the LMF computer drive letter where the CDMA LMF home
directory is located. <lmf home directory> = the directory path or name where the CDMA
LMF is installed
NOTE
The CDMA LMF installation program creates the default home directory c:\wlmf when the CDMA LMF is installed.

Copy CBSC CDF Files to the LMF Computer
Before logging on to a BTS with the LMF to execute optimization/ATP procedures, the correct bts-#.cdf and cbsc–#.cdf files must be obtained from the CBSC and put in a bts-# folder in the LMF computer. This requires creating versions of the CBSC CDF files on a DOS–formatted floppy diskette and using the diskette to install the CDF files on the LMF computer.
3
IMPORTANT
*
The procedure in Table 3-4 lists the steps required to transfer the CDF files from the CBSC to the LMF computer. For any further information, refer to the CDMA LMF Operators Guide (Motorola part number 68P64114A21) or the LMF Help screen..
Table 3-4: Copying CBSC CDF Files to the LMF
Step Action
When copying CDF files, comply with the following to prevent BTS login problems with the LMF.
– The numbers used in the bts#.cdf and cbsc#.cdf filenames must correspond to the locally assigned numbers for each BTS and its controlling CBSC.
– The generic cbsc–1.cdf file supplied with the LMF will work with locally numbered BTS CDF files. Using this file will not provide a valid optimization unless the generic file is edited to replace default parameters (e.g., channel numbers) with the operational parameters used locally.
1 Login to the CBSC workstation. 2 Insert a DOS–formatted floppy diskette in the workstation drive. 3 Type eject –q and press <Enter>. 4 Type mount and press <Enter>.
NOTE
Look for the floppy/no_name message on the last line displayed.If the eject command was previously entered, floppy/no_name will be appended with a number. Use
the explicit floppy/no_name reference displayed when performing step 7.
5 Change to the directory, where the files to be copied reside, by typing cd <directoryname>
(e.g., cd bts248) and pressing <Enter>.
6 Type ls and press the Enter key to display the list of files in the directory.

Table 3-4: Copying CBSC CDF Files to the LMF
Step Action
7 With Solaris versions of Unix, create DOSformatted versions of the bts–#.cdf and cbsc–#.cdf files
on the diskette by entering the following command:
unix2dos <source filename> /floppy/no_name/<target filename> (e.g., unix2dos bts–248.cdf /floppy/no_name/bts–248.cdf).
NOTE
Other versions of Unix do not support the unix2dos and dos2unix commands. In these cases, use the
Unix cp (copy) command. The copied files will be difficult to read with a DOS or Windows text editor because Unix files do not contain line feed characters. Editing copied CDF files on the LMF computer is, therefore, not recommended.
Using cp, multiple files can be copied in one operation by separating each filename to be copied
with a space and ensuring the destination directory (floppy/no_name) is listed at the end of the command string following a space (e.g., cp bts–248.cdf cbsc–6.cdf /floppy/na_name)
8 Repeat steps 5 through 7 for each bts–# that must be supported by the LMF. 9 When all required files have been copied to the diskette, type eject and press <Enter>.
10 Remove the diskette from the CBSC drive. 11 If it is not running, start the Windows operating system on the LMF computer. 12 Insert the diskette containing the bts–#.cdf and cbsc–#.cdf files into the LMF computer. 13 Using Windows Explorer (or equivalent program), create a corresponding bts–# folder in the <lmf
home directory> directory for each bts–#.cdf/cbsc–#.cdf file pair copied from the CBSC.
14 Use Windows Explorer (or equivalent program) to transfer the cbsc–#.cdf and bts–#.cdf files from the
diskette to the corresponding <lmf home directory>\wlmf\cdma\bts–# folders created in step 13.

Creating a Named HyperTerminal Connection for MMI Connection
Apr 2001
SC4812ET BTS Optimization/ATP — CDMA LMF
Confirming or changing the configuration data of certain BTS FRUs requires establishing an MMI communication session between the LMF and the FRU. Using features of the Windows operating system, the connection properties for an MMI session can be saved on the LMF computer as a named Windows HyperTerminal connection. This eliminates the need for setting up connection parameters each time an MMI session is required to support optimization.
Once the named connection is saved, a shortcut for it can be created on the Windows desktop. Double clicking the shortcut icon will start the connection without the need to negotiate multiple menu levels.
Follow the procedures in Table 3-5 to establish a named HyperTerminal connection and create a Windows desktop shortcut for it.

LMF to BTS Connection
The LMF is connected to the LAN A or B connector located on the left side of the frame’s lower air intake grill, behind the LAN Cable Access door (see Figure 3-4).
Table 3-6: LMF to BTS Connection
Step Action
1 To gain access to the connectors, open the LAN Cable Access door, then pull apart the Velcro tape
covering the BNC “T” connector and slide out the computer service tray, if desired (see Figure 3-4).
2
Connect the LMF to the LAN A BNC connector via PCMCIA Ethernet Adapter with an unshielded twisted–pair (UTP) Adapter and 10BaseT/10Base2 converter (powered by an external AC/DC transformer). If there is no login response, connect the LMF to the LAN B BNC connector. If there is still no login response, see Table 6-1, Login Failure Troubleshooting Procedure.
NOTE
– Xircom Model PE3–10B2 or equivalent can also be used to interface the LMF Ethernet
connection to the frame connected to the PC parallel port, powered by an external AC/DC transformer. In this case, the BNC cable must not exceed 91 cm (3 ft) in length.
* IMPORTANT
The LAN shield is isolated from chassis ground. The LAN shield (exposed portion of BNC connector) must not touch the chassis during optimization.

Pinging the Processors
For proper operation, the integrity of the Ethernet LAN A and B links must be be verified. Figure 3-5 represents a typical BTS Ethernet configuration. The drawing depicts one (of two identical) links, A and B.
Ping is a program that sends request packets to the LAN network modules to get a response from the specified “target” module.
Follow the steps in Table 3-7 to ping each processor (on both LAN A and LAN B) and verify LAN redundancy is working properly.
CAUTION
Always wear a conductive, high impedance wrist strap while handling any circuit card/module to prevent damage by ESD.

Step Action
1 From the Windows desktop, click the Start button and select Run. 2 In the Open box, type ping and the GLI2 IP address (for example, ping 128.0.0.2).
NOTE
128.0.0.2 is the default IP address for the GLI2 in field BTS units.
3 Click on the OK button. 4 If the targeted module responds, text similar to the following is displayed:
Reply from 128 128.0.0.2: bytes=32 time=3ms TTL=255
If there is no response the following is displayed:
Request timed out
If the GLI2 fails to respond, it should be reset and re–pinged. If it still fails to respond, typical problems are shorted BNC to inter-frame cabling, open cables, crossed A and B link cables, or the GLI2 itself.

Using CDMA LMF
Basic LMF Operation
NOTE
The terms CDMA LMF and “WinLMF” are interchangeable
Basic LMF Command Line Interface (CLI) Operation
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 iconCommand 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 devicesEnabling devicesDisabling devicesResetting devicesObtaining device statusSorting a status report window
For detailed information on performing these and other LMF operations, refer to the CDMA LMF Operators Guide, 68P64114A78.

Apr 2001
. 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?
This window also contains yes and no buttons. Selecting yes starts the
application. Selecting no terminates the application.

complete explanation of the CLI commands and their use.
IMPORTANT
*
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.
3-22
Logging into a BTS establishes a communications link between the BTS and the CDMA LMF. You may be logged into one or more BTSs 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 3-8 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).

Apr 2001
There may be instances where the BTS initiates a log out due to a system error (i.e., a device
failure).
If the MGLI is OOS_ROM (blue), it will have to be downloaded with code before other devices can
be seen.
If the MGLI is OOS–RAM (yellow), it must be enabled before other installed devices can be seen.

1 Double click the WinLMF CLI desktop icon (if the LMF CLI environment is not already running).
NOTE
If a BTS was logged into under a GUI session when the CLI environment was started, the CLI session will be logged into the same BTS, and step 2 is not required.
2 At the /wlmf prompt, enter the following command:
login bts–
where: host = MGLI card IP address (defaults to address last logged into for this BTS or 128.0.0.2 if this is
first login to this BTS). port = IP port of the TS (defaults to port last logged into for this BTS or 9216 if this is first login to
this BTS)
Logging Out
<bts#> host=<host> port=<port>
Logging out of a BTS is accomplished differently for the GUI and the CLI operating environments.
IMPORTANT
*
The GUI and CLI environments use the same connection to a BTS. If a BTS is logged into in both the GUI and the CLI environments 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.
Logging Out of a BTS from the GUI Environment
Follow the procedure in Table 3-10 to logout of a BTS when using the GUI environment.
Table 3-10: BTS GUI Logout Procedure
