4Aug 2002PRELIMINARY: Incorporate comments from DV&V and engineering.
This document provides information pertaining to the optimization and
audit tests of Motorola SC 4812T Base Transceiver Subsystem (BTS)
equipment frames equipped with trunked high-power Linear Power
Amplifiers (LPAs) and their associated internal and external interfaces.
This document assumes the following prerequisites:
The BTS frames and cabling have been installed per the BTS Frame
Installation manual, which covers the physical “bolt down” of all SC
series equipment frames, and the SC 4812T CDMA BTS Installation
manual, which covers BTS specific cabling configurations.
In most applications the same test procedure is used for all equipment
variations. However, decision break points are provided throughout the
procedure when equipment specific tests are required.
NOTE
As the Code Division Multiple Access (CDMA) Local
Maintenance Facility (LMF) capability comes on-line,
applicable LMF based procedures will be incorporated.
Eventually, only the CDMA LMF platform will be supported as
the recommended customer method of interfacing with and
servicing the SC series BTS equipment.
We at Motorola Technical Education & Documentation have strived to
incorporate into this document the many suggestions and inputs received
from you, the customer, since the inception of the SC product line. At
the same time, we have tried to insure that the scope of the document
targets both the novice and expert site technician and engineer with
the information required to successfully perform the task at hand. If
in some areas, the manual seems to cover the test in too much detail (or
not enough detail) we hope you will keep this in mind.
Optimization Manual: Scope and Layout68P09255A61-4
Document Composition
1
This document covers the following major areas.
Introduction, consisting of preliminary background information (such
as component and subassembly locations and frame layouts) to be
considered by the Cellular Field Engineer (CFE) before optimization
or tests are performed.
Preliminary Operations, consisting of pre-power up tests, jumper
configuration of BTS sub-assemblies, and initial application of power
to the BTS equipment frames. Download of all BTS processor boards,
and LPAs.
Optimization/Calibration, consisting of downloading all BTS
processor boards, LPA verification, radio frequency (RF) path
verification, Bay Level Offset (BLO) calibration, and Radio
Frequency Diagnostic System (RFDS) functions and calibration
Acceptance Test Procedures (ATP), consisting of automated ATP
scripts executed by the LMF and used to verify all major transmit
(TX) and receive (RX) performance characteristics on all BTS
equipment. Also generates an ATP report.
Optional manual performance tests used to verify specific areas of site
operation or to verify regulation compliance. These tests are typically
used to isolate faults down to the module level and information
necessary to better understand equipment operation.
Site turnover after ATP is completed.
Appendices that contain pertinent data sheets that are filled out
manually by the CFE at the site, Pseudorandom Noise (PN) Offset
information, an optimization/ATP matrix , output power data tables,
CDMA operating frequency programming information, manual test
setup information, procedures for verifying that the Voltage Standing
Wave Ratio (VSWR) of all antennas and associated feed lines fall
within acceptable limits, procedures for downloading ROM and RAM
code, and procedures for performing in-service ATP.
The CDMA LMF is a graphical user interface (GUI) based LMF. This
product is specifically designed to provide cellular communications field
personnel the vehicle to support the following CDMA BTS operations:
The LMF uses a GUI, which works in the following way:
Select the device or devices.
Select the action to apply to the selected device(s).
While action is in progress, a status report window displays the action
taking place and other status information.
The status report window indicates when the action is complete and
displays other pertinent information.
Clicking the OK button closes the status report window.
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
cannot be launched from the GUI, only from the desktop icon.
Refer to the LMF CLI Commands, R15.x manual for a complete
explanation of the CLI commands and their use.
Online Help
Task oriented online help is available in the CDMA LMF by clicking on
Help from the menu bar.
Accurate downlink RF power levels are transmitted from the site.
Accurate uplink signal strength determinations are made by the site.
What Is Optimization?
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 for the starter frame starts at the ancillary equipment
frame RFDS RX directional coupler antenna feedline port, through the
ancillary equipment frame RFDS RX directional coupler antenna
feedline port, through the RX input port on the top of the frame,
through the bandpass filter, Combiner Input/Output (CIO) card,
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.
1
NOTE
In this manual, all version of the BBX, MCC, and GLI usable in
this BTS are generically identified as BBX, MCC, or GLI unless
otherwise specified.
The RX path for the expansion frame starts at the ancillary equipment
frame RFDS RX directional coupler antenna feedline port, through the
ancillary equipment frame RFDS RX directional coupler antenna
feedline port, through the RX input port on the top of the starter
frame, through the bandpass filter and CIO card, out the expansion
port at the top of the starter frame, through the expansion cable to the
expansion port on the expansion frame, through the Expansion
Multicoupler Preselector Card (EMPC) and CIO, ending at a BBX slot
in the C-CCP shelf.
The TX path starts at the BBX, through the C-CCP backplane slot,
travels through the LPA/Combiner TX Filter and ends at the top of the
RFDS TX directional coupler antenna feedline port (CDMA), installed
on the ancillary equipment frame. 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. The TX paths are identical for the starter and expansion
frames.
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, it must be prepared for operation. This
preparation includes verifying hardware installation, initial power-up,
download of operating code, and Clock Synchronization Module (CSM)
verification.
Next, the optimization is performed. Optimization includes performance
verification and calibration of all transmit and receive RF paths, and
download of accumulated calibration data.
After optimization, a series of manual pre-ATP verification tests are
covered that address alarm/redundancy tests.
After manual pre-Acceptance Test Procedure (pre-ATP) verification
tests, a series of manual 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 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
Refer to Appendix C for detailed basic guideline tables and detailed
Optimization/ATP Test Matrix outlining the minimum tests that must be
performed anytime a BTS subassembly or RF cable associated with it is
replaced.

The LMF is used in conjunction with Motorola recommended test
equipment and is part of a “calibrated test set”. To ensure consistent,
reliable, and repeatable optimization test results, only recommended test
equipment supported by the LMF must be used to optimize the BTS
equipment.
NOTE
The customer has the responsibility of accounting for any measurement
variances and/or additional losses/inaccuracies that can be introduced
as a result of test equipment substitutions. Before beginning
optimization or troubleshooting, make sure that the test equipment
needed is on hand and operating properly.
Test Equipment Calibration
1
During manual testing, you can, of course, substitute test
equipment with other test equipment models not supported by
the LMF, but those models must meet the same technicalspecifications.
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.

The information in this manual set is intended for use by the cellular
communications craftsperson(s) in the initial installation and
configuration, as well as the day-to-day operation and maintenance of a
BTS.
The user of this information has a general understanding of telephony, as
used in the operation of the Public Switched Telephone
Network (PSTN), and is familiar with these concepts as they are applied
in the cellular and maintenance mobile/portable radiotelephone
environment.
The user also needs a working knowledge of the computer platform
operating system being used (Windows 98 or Windows 2000).
Equipment listed below can be wall mounted or mounted in a
standard 19 inch frame. The description assumes that all

Logical BTS
If equipped with the RFDS option, the RFDS and directional couplers
are the interface between the site antennas and the BTS or Modem
frame. The RFDS equipment includes:
Directional couplers
Site receive bandpass/bandreject filters
RFDS
The BTS software implements the logical BTS capability. Previously, all
BTS frames co-located at a single site had to be identified in the
network with separate and distinct BTS ID numbers. In the Logical BTS
feature, all frames located at a single BTS site are identified with unique
Frame ID numbers (Frame ID Numbers 1, 101, 201, 301) under a single
(site) BTS ID number. A logical BTS can consist of up to four
SC 4812T 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 requires a CDF file that includes equipage
information for all of the logical BTS frames and their devices and a
CBSC file that includes channel data for all of the logical BTS fames.
The first frame of a logical BTS has a -1 suffix (e.g., BTS-812-1 ).
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 is only one tab (e.g., FRAME-282-1 ) for BTS-282. If a logical
BTS has more than one frame, there is a separate FRAME tab for each
frame (e.g. FRAME-438-1 , FRAME-438-101 , and FRAME-438-201
for a BTS-438 that has three frames). If an RFDS is included in the
CDF file, an RFDS tab (e.g., RFDS-438-1) is 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 1-2 and Table 1-3 for specific C-CCP Shelf Device ID numbers.
Table 1-2: C-CCP Shelf/Cage Card/Module Device ID Numbers (Top Shelf)
The BTS is the interface between the span lines to/from the Cellsite Base
Station Controller (CBSC) and the site antennas. This frame is described
in three sections:
The top interconnect plate where all connections are made.
The upper portion of the frame which houses circuit breakers, cooling
fans, and the C-CCP shelf.
The lower portion of the frame which houses the LPA fans, LPAs, and
TX filter/combiners.
The -48 V version of the BTS also has a section below the LPAs
containing a power conversion shelf that supplies power to the LPAs.
Use the illustrations that follow to visually identify the major
components, that make up the Motorola SC 4812T BTS frame.

There are a number of ways to configure the BTS frame. Table 1-4
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.

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 Omni 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. For more information on the differences in site types, please
refer to the BTS/Modem Frame Hardware Installation manual.
NOTE
Site Equipage Verification
CAUTION
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, BBX boards, MCC boards
(per cage), and linear power amplifier assignments are some of the
equipage data included in the CDF.
Be sure that the correct bts-#.cdf and cbsc-#.cdf files are 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
cause system errors. Failure to use the correct CDF files to log
into a live (traffic carrying) site can shut down the site.
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.
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 shipping bag.
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.
The following test equipment is required to complete the pre-power-up
tests:
Digital Multimeter (DMM)

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. After power is verified, cards and modules within the frame
itself will be powered up and verified one at a time.
Before applying any power, verify the correct power feed and return
cables are connected between the power supply breakers and the power
connectors at the top of each BTS frame. Verify correct cable position
referring to Figure 2-3 on page 2-8 for +27 V systems and Figure 2-5
on page 2-10 for -48 V systems.
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.

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.
68P09255A61-4

NOTE
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.
Optimization Process
After a BTS is physically installed and the preliminary operations
(power up) have been completed, use the LMF to calibrate and optimize
the BTS. Motorola recommends that the optimization be accomplished
as follows:
1. Download MGLI-1 with code and data and then enable MGLI-1.
NOTEGLIs may be GLI2s or GLI3s.
2. Use the status function and verify that all of the installed devices of
the following types respond with status information: CSM, BBX,
GLI, 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 must
be corrected before the device can be accessed by the LMF.
3. Download code and data to all devices of the following types:
- CSM
- BBX (may be BBX2 or BBX-1X)
- GLI (other than MGLI-1)
- MCC (may be MCC-8E, MCC24, or MCC-1X)
3-2
4. Download the RFDS TSIC (if installed).
5. Verify the operation of the GPS and HSO or LFR signals.
6. Enable the following devices (in the order listed):
- Secondary CSM
- Primary CSM
- All MCCs
7. Connect the required test equipment for a full optimization.
8. Select the test equipment.
9. Calibrate the TX and RX test cables if they have not previously been
calibrated using the CDMA LMF that will be used for the
optimization/calibration. The cable calibration values can also be
entered manually.
10. 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.
11. If the TX calibration fails, repeat the full optimization for any failed
paths.
12. If the TX calibration fails again, correct the problem that caused the
failure and repeat the full optimization for the failed path.
13. 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.

Cell-Site Data File
NOTE
For more information on the differences in site types, please
refer to the applicable BTS/Modem Frame Hardware Installationand Functional Hardware Description manuals.
The Cell-Site Data File (CDF) contains information that defines the
BTS and data used to download files to the devices. A CDF file must be
placed in the applicable BTS folder before the LMF can be used to log
into that BTS. CDF files are normally obtained from the CBSC using a
floppy disk. A file transfer protocol (ftp) method can be used if the LMF
computer has that capability.
The CDF includes the following information:
Download instructions and protocol
Site specific equipage information
C-CCP shelf allocation plan
- BBX equipage (based on cell-site type) including redundancy
- CSM equipage including redundancy
- MCC (MCC24E, MCC8E, or MCC-1X) 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 redundancy
Effective 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 BBX output
level required to achieve that power level on any channel/sector can
also be determined.
Refer to the CDMA LMF Operator’s Guide for additional
information on the layout of the LMF directory structure
(including CDF 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.
NOTE
3
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.
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 Operator’s Guide, or the LMF
Help screen, for the procedure.
Site Equipage Verification
CAUTION
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 matches the actual site hardware using a CDF conversion
table.
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.
At active sites, the OMC/CBSC must disable the BTS and place
it out of service (OOS). DO NOT remove the 50-pin TELCO
cable connected to the BTS frame site I/O board J1 connector
until the OMC/CBSC has disabled the BTS!
Each frame is equipped with one Site I/O and two Span I/O boards. The
Span I/O J1 connector provides connection of 25 pairs of wire. A GLI
card can support up to six spans. In the SC 4812T configuration, the odd
spans (1, 3, and 5) terminate on the Span “A” I/O; and the even spans (2,
4, and 6) terminate on the Span “B” I/O.
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. Refer to
Figure 3-1 and Figure 3-2 as required.
Table 3-1: T1/E1 Span Isolation
StepAction
1From the OMC/CBSC, disable the BTS and place it OOS. Refer to SC OMC-R/CBSC System
Operator Procedures.
- The T1/E1 span 50-pin TELCO cable connected to the BTS frame SPAN I/O board J1 connector
can be removed from both Span I/O boards, if equipped, to isolate the spans.
3
NOTE
If a third party is used for span connectivity, the third party must be informed before disconnecting the
span line.
Verify that you remove the SPAN cable, not the “MODEM/TELCO” connector.

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.
! CAUTION
- The LAN shield is isolated from chassis ground. The LAN shield (exposed portion of BNC
connector) must not touch the chassis during optimization.

NOTE
For the CDMA LMF graphics to display properly, the computer
platform must be configured to display more than 256 colors.
See the operating system software instructions for verifying and
configuring the display settings.
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.”
Follow the procedure in Table 3-3 to install the LMF operating system.

NOTE
First Time Installations:
- Install U/WIN (First)
- Install Java Runtime Environment (Second)
- Install LMF Software (Third)
- Install/Create BTS Folders (Fourth)
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.
Copy CDF Files from CBSC
Before the LMF can execute the optimization/ATP procedures for the
BTS, the correct bts-#.cdf and cbsc-#.cdf files must be
obtained from the CBSC and put in a bts-# folder in the LMF
notebook. This requires copying the CBSC CDF files to a DOS
formatted diskette, and using the diskette to install the CDF file in the
LMF.
3-8
Follow the procedure in Table 3-4 to obtain the CDF files from the
CBSC and copy the files to a diskette. For any further information, refer
to the CDMA LMF Operator’s Guide or the LMF Help screen.
If the LMF has ftp capability, the ftp method can be used to copy
the CDF files from the CBSC.
On Sun OS workstations, the unix2dos command can be used in
place of the cp command (e.g., unix2dos bts-248.cdf
bts-248.cdf). This should be done using a copy of the CBSC
CDF file so the original CBSC CDF file is not changed to DOS
format.
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 works
with locally numbered BTS CDF files. Using this file doesnot provide a valid optimization unless the generic file is
edited to replace default parameters (e.g., channel numbers)
with the operational parameters used locally.
Table 3-4: Copying CBSC CDF Files to the LMF

StepAction
AT THE CBSC:
1Login to the CBSC workstation.
2Insert a DOS formatted diskette in the workstation drive.
3Type eject -q and press the <Enter> key.
4Type mount and press the <Enter> key.
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.
5Change to the directory containing the file by typing cd <directory name> (ex. cd
bts-248 ) and pressing <Enter>.
6Type ls <Enter> to display the list of files in the directory.
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
3
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).
8Repeat steps 5 through 7 for each bts-# that must be supported by the LMF.
9When all required files have been copied to the diskette, type eject and press the <Enter> key.
10Remove the diskette from the CBSC.
AT THE LMF:
11Start the Windows operating system.
12Insert the diskette into the LMF.
13Using Windows Explorer (or equivalent program), create a corresponding bts-# folder in the
<lmf home directory>\cdma directory for each bts-#.cdf/cbsc-#.cdf file pair copied from the
CBSC.
14Use Windows Explorer (or equivalent program) to transfer the cbsc-#.cdf and bts-#.cdf files from
the diskette to the corresponding <lmf home directory>\cdma\bts-# folders created in step 13.
Creating a Named HyperTerminal Connection for MMI Connection
Confirming or changing the configuration data of certain BTS Field
Replaceable Units (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.
3-10
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 procedure in Table 3-5 to establish a named HyperTerminal
connection and create a WIndows desktop shortcut for it.
Table 3-5: Creating a Named Hyperlink Connection for MMI Connection

Folder Structure Overview
Figure 3-3: LMF Folder Structure
The LMF uses an <lmf home directory> folder that contains all of the
essential data for installing and maintaining the BTS. The list that
follows outlines the folder structure for the LMF. Except for the bts-nnn
folders, these folders are created as part of the the LMF installation.
Refer to the CDMA LMF Operator’s Guide for a complete description of
the folder structure.
(C:)
x:\<lmf home directory> folder
cdma folder
BTS-nnn folders (A separate folder is
required for each BTS where bts-nnn is the
unique BTS number; for example, bts-163.)
loads folder
version folder (A separate folder is
required for each different version; for
example, a folder name 2.8.1.1.1.5.)
3-12
code folder
data folder
NOTE
The “loads” folder and all the folders below it are not available
from the LMF for Software Release 2.16.1.x. These folders may
be present as as a legacy from previous software versions or
downloaded from the CBSC/OMC-R.
For proper operation, the integrity of the Ethernet LAN A and B links
must be be verified. Figure 3-4 represents a typical BTS Ethernet
configuration. The drawing depicts one (of two identical) links, A and B.
Ping is a program that routes request packets to the LAN network
modules to obtain a response from the specified “targeted” BTS.

Follow the procedure in Table 3-6 and refer to Figure 3-5 or Figure 3-6,
as required, to ping each processor (on both LAN A and LAN B) and
verify LAN redundancy is operating correctly.
Always wear a conductive, high impedance wrist strap while
handling any circuit card/module to prevent damage by ESD.
The Ethernet LAN A and B cables must be installed on each
frame/enclosure before performing this test. All other processor
board LAN connections are made via the backplanes.
1If you have not already done so, connect the LMF to the BTS (see Table 3-2 on page 3-6).
2From the Windows desktop, click the Start button and select Run.
3In the Open box, type ping and the <MGLI IP address> (for example, ping 128.0.0.2).
NOTE
128.0.0.2 is the default IP address for MGLI-1 in field BTS units. 128.0.0.1 is the default IP
address for MGLI-2.

4Click on the OK button.
5If the connection is successful, 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 MGLI fails to respond, reset and perform the ping process again. If the MGLI still fails to
respond, typical problems are shorted BNC to inter-frame cabling, open cables, crossed A and B
link cables, missing 50-Ohm terminators, or the MGLI itself.
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 icon
Command 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:
Obtaining device status
Sorting a status report window
For detailed information on performing these and other LMF operations,
refer to the CDMA LMF Operator’s Guide.
Graphical User Interface Overview
The LMF uses a GUI, which works in the following way:
Select the device or devices.
Select the action to apply to the selected device(s).
While action is in progress, a status report window displays the action
taking place and other status information.
The status report window indicates when the the action is complete
and displays other pertinent information.
Clicking the OK button closes the status report window.
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 Due to architectural limitations, 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
3
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.
CLI Format Conventions
The CLI command can be broken down in the following way:
- equals signs (=) between the keywords and the parameter values
- parameter values
Spaces are required between the verb, device, switch, and option
parameters. A hyphen is required between the device and its identifiers.
Following is an example of a CLI command.
measure bbx-<bts_id>-<bbx_id> rssi channel=6 sector=5
Refer to LMF CLI Commands for a complete explanation of the CLI
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 invalid optimization. Failure to use the correct CDF
files to log into a live (traffic carrying) site can shut down the
site.
Logging into a BTS establishes a communications link between the BTS
and the CDMA LMF. You may be logged into more than one BTS 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 3-2).
Prerequisites
Before attempting to login to a BTS, ensure the following have been
completed:
The LMF operating system 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 is
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 3-2 and Figure 3-2).

BTS Login from the GUI Environment
Follow the procedure in Table 3-7 to log into a BTS when using the GUI
environment.
Table 3-7: BTS GUI Login Procedure
StepAction
1Start the CDMA LMF GUI environment by double clicking on the WinLMF desktop icon (if the LMF
is not running).
NOTE
If a warning similar to the following is displayed, select No, shut down other LMF sessions which
may be running, and start the CDMA LMF GUI environment again:
The CLI handler is already running.
This may cause conflicts with the LMF
Are you sure you want to start the application?
YesNo
2Click on the Login tab (if not displayed).
3If no base stations are displayed in the Available Base Stations pick list, double click on the CDMA
4Click on the desired BTS number.
5Click on the Network Login tab (if not already in the forefront).
6Enter the correct IP address (normally 128.0.0.2 for a field BTS) if not correctly displayed in the IP
Address box.
68P09255A61-4
NOTE
128.0.0.2 is the default IP address for MGLI-1 in field BTS units. 128.0.0.1 is the default IP address
3
for MGLI-2.
7Type in the correct IP Port number (normally 9216) if not correctly displayed in the IP Port box.
8Click on Ping.
- If the connection is successful, the Ping Display window shows text similar to the following:
Reply from 128 128.0.0.2: bytes=32 time=3ms TTL=255
- If there is no response the following is displayed:
128.0.0.2:9216:Timed out
If the MGLI fails to respond, reset and perform the ping process again. If the MGLI still fails to
respond, typical problems are shorted BNC to inter-frame cabling, open cables, crossed A and B link
cables, missing 50-Ohm terminators, or the MGLI itself.
9Change the Multi-Channel Preselector (from the Multi-Channel Preselector pick list), normally
MPC, corresponding to your BTS configuration, if required.
NOTE
When performing RX tests on expansion frames, do not choose EMPC if the test equipment is
connected to the starter frame.
10Click on the Use a Tower Top Amplifier, if applicable.
Click on Login.
11
A BTS tab with the BTS is displayed.
NOTE
If you attempt to login to a BTS that is already logged on, all devices will be gray.
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.
Follow the procedure in Table 3-8 to log into a BTS when using the CLI
environment.
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
logout has occurred.
Table 3-8: BTS CLI Login Procedure
StepAction
1Double 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.
2At the /wlmf prompt, enter the following command:
login bts-<bts#> host=<host>
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 BTS (defaults to port last logged into for this BTS or 9216 if this is first login to
this BTS).
port=<port>
3
A response similar to the following will be displayed:
LMF>
13:08:18.882 Command Received and Accepted
COMMAND=login bts-33
Logging out of a BTS is accomplished differently for the GUI and the
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
logout has occurred.
3
Logging Out of a BTS from the GUI Environment
Follow the procedure in Table 3-9 to logout of a BTS when using the
GUI environment.
Table 3-9: BTS GUI Logout Procedure
StepAction
1Click on BTS on the BTS tab menu bar.
2Click the Logout item in the pull-down menu.
A Confirm Logout pop-up message appears.
3Click on Yes or press the <Enter> key to confirm logout.
You are returned to the Login tab.
NOTE
If a logout was previously performed on the BTS from a CLI window running at the same time as the
GUI, a Logout Error pop-up message appears stating the system should not log out of the BTS.
When this occurs, the GUI must be exited and restarted before it can be used for further operations.
4If a Logout Error pop-up message appears stating that the system could not log out of the Base
Station because the given BTS is not logged in, perform the following actions:
- Click OK.
- Select File>Exit in the window menu bar.
- Click Yes in the Confirm Logout pop-up.
- Click Yes in the Logout Error pop-up which appears again.
5If further work is to be done in the GUI, restart it.
NOTE
The Logout item on the BTS menu bar will only log you out of the displayed BTS.
You can also log out of all BTS sessions and exit LMF by clicking on the File selection in the menu
bar and selecting Exit from the File menu list. A Confirm Logout pop-up message will appear.
