Optimization Manual Scope and Layout
Manual Scope and Layout
This document provides information pertaining to the optimization and
audit tests of the Motorola SC4812ET Lite Radio Frequency (RF) Base
Transceiver Station (BTS) equipment frame and its associated internal
and external interfaces in stand-alone and companion frame
installations. The following subjects are addressed: preliminary
background information; optimization and alarm/redundancy tests;
Acceptance Test Procedures (ATP) to verify site operation and regulation
compliance; site turnover; troubleshooting.
Most applications use the same test procedure for all equipment
variations. However, decision break points are provided throughout the
procedure when equipment-specific tests are required. For example,
when tests using external test equipment are performed instead of those
using the RFDS, additional test procedures and illustrations are provided
to cover both applications.
This optimization procedure consists of a group of task-oriented tests.
Each major test category (Audit, Initial power-up, Calibration, etc.) is
described in chapters which are broken down into multi-page
information “maps.”
Each “map” contains the information necessary to perform the test or
operation. Included are all required input levels, output levels, Local
Maintenance Facility (LMF) application software commands, and test
point identification. Also described are important test process concepts
and equipment operation which should be understood by the operator.
Whenever possible, graphics, flowcharts, or written examples
complement the information or procedural steps.
Assumptions and Prerequisites
This document assumes that the BTS frames and cabling have been
installed per the Frame Mounting Guide Analog/CDMA/TDMA;68P09226A18, which covers the physical “bolt down” of all SC series
equipment frames, and the SC4812ET Lite Installation; 68P09253A36,
which covers BTS-specific cabling configurations.

Purpose of the Optimization
68P09255A69-3
1
Purpose of the Optimization
Why Optimize?
Proper optimization and calibration ensures that:
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. 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 and cause improper site
operation.
What Happens During Optimization?
Overview - During optimization, the accumulated path loss or gain is
first determined for each RF transmit path in the BTS. These transmit
path loss or gain values are then stored in a database along with RF
receive path default values.
RF path definitions - For definitions of the BTS transmit (TX) and
receive (RX) paths, see “What is Bay Level Offset Calibration?” in the
Bay Level Offset Calibration section of Chapter 3.
RF paths and transceiver optimization - Six of the seven Broad Band
Transceiver (BBX) boards in each SCCP shelf are optimized to specific
RX and TX antenna connectors. The seventh BBX board acts in a
redundant capacity for BBX boards 1 through 6, and is optimized to all
antenna connectors. A single optimization value is generated for each
complete path. This eliminates the accumulation of error that would
occur from individually measuring and summing the gain and loss of
each element in the path.
Using RF path gain/loss values - BTS equipment factors in the derived
optimization values internally to adjust transceiver power levels, leaving
only site-specific antenna feedline loss and antenna gain characteristics
to be factored in by the CFE when determining required site Effective
Radiated Power (ERP) output power levels.

When to Optimize68P09255A69-3
When to Optimize
New Installations
1
The following operations and optimization/test actions should be
accomplished for a new BTS or frame installation:
1. After the initial site installation, the BTS must be prepared for
operation. This preparation includes verifying hardware installation,
initial power-up, downloading of operating code, verifying GPS
operation, and verifying transmit and receive paths.
2. Next, the optimization is performed. Optimization includes
performance verification and calibration of all transmit and receive
RF paths, and download of accumulated calibration data.
3. A calibration audit of all RF transmit paths may be performed any
time after optimization to verify BTS calibration.
4. After optimization, a series of manual pre-Acceptance Test
Procedure (ATP) verification tests are performed to verify
alarm/redundancy performance.
5. After manual pre-ATP verification tests, an ATP is performed to
verify BTS performance. An ATP is also required to demonstrate
regulation compliance before the site can be placed in service.
Site Expansion
Periodic Optimization
Repaired Sites
NOTE
Optimization is required after expansion of a site with additional BTS
frames.
Periodic optimization of a site may also be required, depending on the
requirements of the overall system.
Refer to Appendix B for a detailed FRU Optimization/ATP Test
Matrix outlining the minimum tests that must be performed anytime a BTS RF subassembly or cable associated with an RF path
is replaced.

Required Test Equipment and Software
Policy
To ensure consistent, reliable, and repeatable optimization test results,
test equipment and software meeting the following technical criteria
should be used to optimize the BTS equipment. Test equipment can, of
course, be substituted with other test equipment models if the equipment
meets the same technical specifications.
It is the responsibility of the customer to account 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
Optimum system performance and capacity depend on regular equipment
service and calibration prior to BTS optimization. Follow the original
equipment manufacturer (OEM) recommended maintenance and
calibration schedules closely.
Test Cable Calibration
Equipment Warm-up
Test cables can make critical differences in optimization accuracy. It is
recommended that cable calibration be run at every BTS with the
complete test equipment set. 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 to account for cable loss is by entering it into the LMF
during the optimization procedure. This method requires accurate test
cable characterization using shop test equipment. Characterized cables
should be tagged with the characterization information, and the
measured losses entered into the LMF before field optimization.
After arriving at a site, test equipment should be plugged in and turned
on immediately to provide the longest possible time for warm up and
stabilization. The following pieces of test equipment must be warmed up
for a minimum of 60 minutes prior to use for BTS optimization or RFDS
calibration:
Communications test set.

BTS Equipment Identification68P09255A69-3
BTS Equipment Identification
Equipment Overview
Frame - The SC4812ET Lite BTS frame consists of a single, outdoor,
weatherized cabinet containing RF and power components. The BTS is
functionally similar to the two-cabinet SC4812ET, but provides more
flexibility in site selection because of its smaller footprint and lower
weight. The BTS is powered by 208/240 Vac (North American frame) or
230 Vac (International frame), rectified internally to +27 Vdc, and can
support up to two carriers in a 3-sector configuration. Six-sector
operation is not supported with any SC4812ET Lite configuration.
Frame Configurations - The SC4812ET Lite is available in starter and
companion frame configurations. Following are brief descriptions of
each:
1. Starter - This frame configuration is available with one- and
two-carrier capability with separate antenna sets for each carrier. It
can operate as a stand-alone BTS, or can be modified in the field to
the companion frame configuration.
2. Companion - This frame configuration is available with one- and
two-carrier capability using 2:1 TX combiners and a single antenna
set for the frame. It operates with another SC4812ET Lite
companion frame which has its own antennas and different carriers.
Companion frames share RX signals to provide diversity RX for the
opposite frame. Companion frames allow equipping a single
SC4812ET Lite site with up to four carriers. Each companion frame
is managed in the Base Station System (BSS) as a separate BTS.
1
Internal components - The BTS frame houses the fan modules, RF
compartment heat exchanger, Small CDMA Channel Processor (SCCP)
shelf, RF Linear Power Amplifier (LPA) modules, LPA trunking
modules, bandpass filters or 2:1 combiners, and Duplexer Directional
Couplers (DRDC) or Triplexer Directional Couplers (TRDC). Power
system components include an AC Load Center (ACLC), rectifiers, a
+27 Vdc Power Distribution Assembly (PDA), backup batteries, battery
heaters, and one duplex GFCI 115 Vac utility outlet.
BTS, Frame, Span, and Device Numbering
BTS and frame numbering - An SC4812ET Lite is a single-frame
BTS. Within a BTS, all RF Modem Frames (RFMF) are identified as
parts of a single, numbered BTS (for example, BTS-812) . Each RFMF
is assigned a unique frame number. SC4812ET Lite BTSs consisting of
either a starter or a companion frame have a single RFMF. Because of
this, each frame is numbered as a BTS -1 frame of its own unique BTS
number. As an example, at a site with two frames in a companion
configuration, each frame would have a different BTS number, such as
BTS-812 and BTS-813 . Each frame would be numbered as frame -1 of
its BTS: BTS-812-1 and BTS-813-1 .
Span numbering - Figure 1-1 shows the frame span configuration for a
BTS consisting of an SC4812ET Lite starter or companion frame. The
figure also shows the BTS-to-CBSC Transcoder span configurations
which can be employed with an SC4812ET Lite BTS.

Battery Heaters
The battery heater pads warm the batteries to provide improved
cold-weather performance. A separate heater pad is required for each
battery string and is located between each battery string and its
respective support shelf.
Channel Service Units (CSU) (Optional)
The SC4812ET Lite can be equipped with up to two M-PATH 537 CSU
modules for T1 spans or two M-PATH 437 CSU modules for E1 spans.
These modules install in the CSU shelf (Figure 1-3). The CSUs allow
monitoring of span performance and provide capability for remote
network management.
CSU Shelf
The CSU shelf is an ADC Kentrox 2-slot Universal Shelf which can
accommodate two M-PATH 537 or two M-PATH 437 CSU modules.
When the optional CSU modules are not installed, cover plates are
installed over the CSU card slots (Figure 1-3).
DC Power Distribution Assembly (PDA)
Both rectifier output voltage and back-up battery voltage are routed to
the PDA (Figure 1-3) where they are combined into system DC bus
voltage. The PDA provides distribution of DC power and system DC
bus protection from the loads with MAIN BREAKER and the smaller
post-distribution circuit breakers. MAIN BREAKER permits removal of
all frame loading from the bus. The 13 post-distribution circuit breakers
permit removal of individual loads.
DRDCs permit duplexing of sector transmit and receive signals on a
single antenna. The DRDCs also incorporate a receive bandpass filter
and dual directional couplers which permit signal monitoring by the RF
Diagnostic Subsystem.
ET Interface Board (ETIB) and LPA Control (LPAC)
Board
The ETIB is an interconnect module with status LEDs, MMI receptacles,
and secondary surge protection for the LPA modules. The LPAC board
provides the interface for the LPA connections (Figure 1-3).
Filter/Combiner Shelf (Bandpass Filters or 2:1
Combiners)
The filter/combiner shelf (Figure 1-3) holds the transmit bandpass filters
or 2:1 combiners, depending on system configuration.
Heat Exchanger
The heat exchanger provides cooling to the frame RF compartment. The
fan speed of the heat exchanger adjusts automatically with temperature.
The heat exchanger is located in the frame main door (Figure 1-2).

Span I/O Boards
The two span I/O boards, Span I/O A and Span I/O B (Figure 1-3),
provide the span line interface from the punchblock or the CSU
modules, if equipped, to the SCCP backplane.
TRDCs provide separate, bandpass-filtered sector transmit and receive
paths. When TRDCs are used, separate transmit and receive antennas are
required for each sector. As with DRDCs, dual directional couplers for
each antenna path are incorporated in TRDCs to permit signal
monitoring by the RFDS.

SCCP Cage Configuration and 1X Devices
SC4812ET Lite frames have one SCCP cage which will support up to
four MCC cards and six BBX cards.
MCC Cards
A BTS may be configured with a mix of MCC-8E, MCC-24E, and
MCC-1X cards. Any SCCP cage MCC card slot will support any of the
three MCC types. For 1X capability under R16.0, at least one MCC card
must be an MCC-1X which can be installed in any MCC card slot. In a
BSS operating with Software Release 2.16.0.84.3 and higher, MCC-1X
cards will support IS-95A and B traffic as well as CDMA2000 1X.
When operating with Software Release 2.16.0.5x.x, the MCC-1X cards
do not support IS-95A/B operation. For additional software release
compatibility and capability information, contact the local Motorola
account team.
BBX Cards
Up to six BBX cards of mixed BBX2s and BBX-1Xs can also be
supported. SCCP cage BBX2 card slots 1 through 6 are carrier- and
sector-dependent. As a result, the BBX slots dedicated to the sectors for
one carrier should be populated with the same type of cards. Refer to
Table 1-5 for BBX card slot carrier and sector correlations.
The SCCP cage R1 card slot is dedicated to the redundant BBX. This
slot will support either a BBX2 or a BBX-1X. If a cage has BBX-1X
carriers, the redundant BBX (BBXR) must be a BBX-1X card to provide
1X redundancy.
BBX-1X and BBX2 Interchangeability
In a BSS operating with R16.0 software, BBX-1X cards can be used as
direct replacements for BBX2 cards; however, different types of BBXsshould not be mixed on the same carrier. Therefore, if a BBX2 card is
replaced with a BBX-1X, all remaining BBX2 cards for the carrier
supported by the replaced card must also be replaced with BBX-1X
cards.

documentation supplied for each BTS application.. This includes
verifying module placement, jumper, and dual in-line package (DIP)
switch settings. Next, pre-power up and initial power-up procedures are
presented. Finally, power-down and normal power-up procedures are
covered.
Sites are configured as 3-sector with one or two carriers. Each type has
unique characteristics and must be optimized accordingly.
The Configuration Data File (CDF), also called Cell-site Data File,
contains site type and equipage data information. The LMF application
program reads data directly from the CDF during optimization. The
number of BTS frames, number and types of BBX and MCC boards, and
linear power amplifier assignments are some of the equipage data
included in the CDF.
Site Equipage Verification
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 frame.
CAUTION
Always wear an approved anti-static 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 packaging in which it was
shipped.

Before applying any power to the BTS frame, follow the procedure in
Table 2-3 to verify there are no shorts in the DC power distribution
system.
NOTE
Table 2-3: DC Power System Pre-Power Application Test
The procedure in Table 2-3 is required only on initial frame
power-up or following maintenance when any major power
components (e.g., ACLC, DC PDA, Meter Alarm Panel) were
replaced or internal DC power cables were disconnected.
StepAction
1Physically verifyall ACLC front-panel circuit breakers (Figure 2-4) are OFF (down), all DC PDA
circuit breakers (Figure 2-6) are set to OFF (pulled out), and all battery shelf circuit breakers
(Figure 2-3) are OFF (pulled out).
2Visually ensure that all AC rectifier modules (Figure 2-3) are not powered (DC, PWR, and bar graph
LEDs are not lighted), that the MAP power switch (Figure 2-9) is OFF, and that no LEDs on the
MAP are lighted.
3Inside the battery compartment, measure the voltage between the + (red) and - (black) battery bus
bars. There should be no 27 Vdc present.
4
NOTE
Do not unseat the AC rectifier modules in the following step.
Perform the following:
4a- In the frame RF compartment, unseat all circuit boards/ modules (except CCD and CIO cards) in
the SCCP shelf, but leave them in their respective slots.
4b- In the frame LPA compartment, disconnect the Linear Power Amplifier (LPA) cables from the
compartment bulkhead feed-through connector.
5Set the DMM to measure resistance, and inside the battery compartment, measure the resistance
between the + (red) and - (black) battery bus bars. The resistance should measure >
1 ΜΩ.
6Leave the DMM set to measure resistance, and insert the probes into the MAP VOLT and AMP TEST
POINTS (Figure 2-9). Place the (+) DMM probe into the (-) AMP TEST POINT. Place the (-) DMM
probe into the (-) VOLT TEST POINT. Resistance should measure greater than 750 Ω.

Battery Charge Test (Connected Batteries)
Table 2-7 lists the step-by-step instructions for testing the battery
charging performance.
2
Table 2-7: Battery Charge Test (Connected Batteries)
StepAction
1Close the battery shelf circuit breakers (Figure 2-3) for connected batteries only. This process should
be completed quickly to avoid individual battery strings drawing excess charge current
NOTE
If the batteries are sufficiently discharged, the battery circuit breakers may not engage individually
due to the surge current. If this condition occurs, disconnect the batteries from the 27Vdc bus by
setting the MAP power switch to OFF, and then engage all the connected battery circuit breakers.
The MAP power switch should then be turned ON.
Using the clamp-on DC current probe and DMM, measure the current in each of the battery string
2
connections to the battery bus bars. 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.
NOTE
The MAP AMP display will indicate the total current output of the rectifiers during this procedure.
As an alternative, the bar graph meters on the AC rectifier modules can be used as a rough estimate of
the total battery charge current. Each rectifier module bar graph has eight (8) LED elements to
represent the output current. Each illuminated LED element indicates that approximately 12.5% (1/8
or 8.75 Amps) of an individual rectifier’s maximum current output (70 Amps) is flowing.
RECTIFIER BAR GRAPH EXAMPLE:
Question: A system fitted with three (3) rectifier modules each have three bar graph LED elements
illuminated. What is the total output current into the batteries?
Answer: Each bar graph is indicating approximately 12.5% of 70 amps, therefore, 3 x 8.75 equals
26.25 amps per rectifier. As there are three rectifiers, the total charge current is equal to (3 x 26.25 A)
78.75 amps.
This charge current calculation is only valid when the RF and LPA compartment electronics are not
powered on, and the RF compartment heat exchanger is turned off. This can only be accomplished if
the DC PDA MAIN BREAKER is set to OFF.
3The current in each string should be approximately equal (within + 5 amps).
4Allow 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 amps.
Recheck the DC output voltage. It should remain the same as measured in step 4 of the frame DC
5
Power Application and Test (Table 2-6).
2-16
NOTE
If discharged batteries are installed, the MAP AMP display may indicate approximately 288 amps for
a two-carrier frame (four rectifiers) or 216 amps for a single-carrier frame (three rectifiers).
Alternately, all bar graph elements may be lighted on the rectifiers during the charge test. Either
indication shows 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.

checking current levels.
Table 2-8: Battery Discharge Test
StepAction
1Turn the BATT TEST switch on the MAP ON (Figure 2-9). The rectifier output voltage and current
should decrease by approximately 10% as the batteries assume the load. Alarms for the MAP may
occur.
2Measure the individual battery string current using the clamp-on DC current probe and DMM. The
battery discharge current in each string should be approximately the same (within +
5 amps).
3Turn BATT TEST switch OFF.
CAUTION
Failure to turn off the MAP BATT TEST switch before leaving
the site will result in low battery capacity and reduce battery life.

Optimization Process Overview
After a BTS is physically installed and the preliminary operations, such
as power up, have been completed, the LMF is used to optimize the
BTS. Companion frames must be optimized individually as separate
BTSs. The basic optimization process consists of the following:
Download MGLI (GLI-bts#-1) with application code and data and
then enable MGLI.
Use the LMF status function and verify that all of the installed devices
of the following types respond with status information: CSM, BBX,
GLI, MCC8, and, if RFDS is installed, TSU or RFDS-1X RPROC. 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.
Download device application code and data to all devices of the
following types:
- CSM
- BBX
- Remaining GLI (GLI-bts#-2)
- MCC
Download the RFDS TSIC or RFDS-1X RPROC (if installed).
3-2
Verify the operation of the GPS and HSO signals.
Enable the following devices (in the order listed):
- Secondary CSM (slot CSM 2)
- Primary CSM (slot CSM 1)
- All MCCs
Using the LMF test equipment selection function, select the test
equipment to be used for the calibration.
Calibrate the TX and RX test cables if they have not previously been
calibrated with the LMF computer and software build which will be
used for the optimization/calibration. Cable calibration values can be
entered manually, if required.
Connect the required test equipment for a full optimization.
Select all of the BBXs and all of the MCCs and use the full
optimization function. The full optimization function performs TX

NOTE
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 unreliable or improper site
operation.

CAUTION
If it has not already been done, review and verify the site equipage data
in the CDF with the actual site hardware and the site engineering
documentation. Use a text editor to view the CDF contents.
- Use extreme care not to make any changes to the CDF
content while viewing the file. Changes to the CDF can
cause the site to operate unreliably or render it incapable of
operation.
- Always wear an approved anti-static 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 packaging in which it was shipped.
BTS Software Release Download
The correct device initialization code (ROM code) for the Software
Release being used by the Base Station System (BSS) (for example
R16.0.x) must be successfully downloaded to the BTS processor boards
before optimization can be performed. Device initialization code is
normally downloaded to the processor boards from the CBSC using the
DownLoad Manager (DLM). For optimization, device application code
(RAM code) and data is loaded at the cell site from the LMF computer.

Copy CBSC CDF Files to the LMF Computer
Before logging on to a BTS with the LMF computer 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.
NOTE
When copying CDF files, comply with the following to prevent
BTS login problems with the Windows 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 Windows 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.

Use the explicit floppy/no_name reference displayed when performing step 7.
5Change to the directory, where the files to be copied reside, by typing cd <directoryname>
(e.g., cd bts-248) and pressing the Enter key.

6Type ls and press the Enter key to display the list of files in the directory.
7With Solaris versions of Unix, create DOS-formatted versions of the bts-#.cdf and cbsc-#.cdf files on
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/no_name).
8Repeat steps 5 through 7 for each bts-# which must be supported by the LMF computer.
9When all required files have been copied to the diskette type eject and press the Enter key.
10Remove the diskette from the CBSC drive.
11If it is not running, start the Windows operating system on the LMF computer.
12Insert the diskette containing the bts-#.cdf and cbsc-#.cdf files into the LMF computer.
13Using MS Windows Explorer, create a corresponding bts-# folder in the <x>:\<lmf home
directory>\cdma directory for each bts-#.cdf /cbsc-#.cdf file pair copied from the CBSC.
14Use MS Windows Explorer to transfer the cbsc-#.cdf and bts-#.cdf files from the diskette to the
corresponding <x>:\<lmf home directory>\cdma\bts-# folders created in step 13.

2If it is not running, start the MS Windows operating system on the LMF computer. If the computer is
running and the LMF is logged into a BTS, logout and exit the program.
3Start MS Windows Explorer from the Windows desktop by selecting Start > Programs > Windows
Explorer.
4In the left-hand pane of MS Windows Explorer, locate the <lmf home directory> folder on x:\ drive
(installation default is c:\wlmf), and expand it (click on the “+” symbol next to the folder) to display
the cdma and help folders.
5Expand the cdma folder, locate the loads folder, and expand it.
6Determine if there is a 2.16.0.x.x folder with final numbers as specified for the software release used
in the BSS (for example, 2.16.0.84.4).
- If no folder of the correct revision level exists, obtain the latest Software Release 2.16.0.x.x
device binary files from Motorola and copy them onto the LMF computer in the <x>:\<lmf homedirectory\cdma\loads\<codeload#> directory.
- If a <codeload#> folder of the correct revision level exists, proceed to step 7.
7Expand the 2.16.0.x.x folder to display the code and data folders.
8In the left-hand pane, click on the code folder, and in the right-hand pane look for the following files,

Creating a Named HyperTerminal Connection for MMI Communication
Confirming or changing the configuration data of certain BTS Field
Replaceable Units (FRU) requires establishing an MMI communication
session between the LMF computer 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 3-4 to establish a named HyperTerminal
connection and create a Windows desktop shortcut for it.
