NOTE
FCC Part 68 Requirements
This equipment complies with Part 68 of the Federal Communications
Commission (FCC) Rules. 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

PRELIMINARY
Manual Scope and Layout
This document provides information pertaining to the optimization and
audit tests of the Motorola SC4812ET Lite RF Base Transceiver Station
(BTS) equipment frame and its associated internal and external
interfaces. 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 tests, etc.)
is described in chapters which are broken down into multi-page “maps.”
Each “map” typically consists of pages containing all the information
necessary to perform the test (including all required input levels, output
levels, CDMA Local Maintenance Facility (CDMA LMF) commands,
and test points required). Also described are some of the main concepts
you must understand in the test process. Whenever possible, graphics,
flowcharts, or other examples complement the information/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
08/01/2001 1-3
1X SCt4812ET Lite BTS Optimization/ATP
PRELIMINARY
Why Optimize?
Proper optimization and calibration ensures that:
SAccurate downlink RF power levels are transmitted from the site.
SAccurate 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
Optimization identifies the accumulated loss (or gain) for each receive
and transmit path at the BTS site, and stores these values in a database.
SA receive path (RX) starts at the Duplexer Directional Coupler
(DRDC) or Transmit & Receive Dual Directional Coupler (TRDC)
antenna feedline port and travels through the DRDC/TRDC, the
Multi–coupler Preselector Card (MPC) and additional splitter
circuitry, ending at a Broad Band Transceiver (BBX) backplane slot in
the Small CDMA Channel Processor (SCCP) shelf.
SA transmit path (TX) starts at the SCCP shelf BBX backplane slot, is
routed to the Linear Power Amplifier (LPA) Trunking Module,
through the LPAs, back through the LPA Trunking Module, through
the bandpass filter or 2–cavity combiner, and ends at the
DRDC/TRDC antenna feedline port.
Six of the seven BBX2 boards in each SCCP shelf are optimized to
specific RX and TX antenna ports. The seventh BBX2 board acts in a
redundant capacity for BBX2 boards 1 through 6, and is optimized to all
antenna ports. A single value is generated for each complete 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.
BTS equipment factors in these values 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.

When to Optimize
PRELIMINARY
1X SCt4812ET Lite BTS Optimization/ATP 08/01/2001
1-4
New Installations
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.
Next, the optimization is performed. Optimization includes performance
verification and calibration of all transmit and receive RF paths, and
download of accumulated calibration data.
A calibration audit of all RF transmit paths may be performed any time
after optimization to verify BTS calibration.
After optimization, a series of manual pre–Acceptance Test Procedure
(ATP) verification tests are performed to verify alarm/redundancy
performance.
After manual pre–ATP verification tests, a series of ATPs are performed
to verify BTS performance. An ATP is also required before the site can
be placed in service.
Site Expansion
Optimization is also required after expansion of a site with additional,
interconnected BTS frames.
Periodic Optimization
Periodic optimization of a site may also be required, depending on the
requirements of the overall system.
Repaired Sites
Refer to Appendix B for a detailed FRU Optimization/ATP
Test Matrix outlining the minimum tests that must be
performed any time a BTS subassembly or RF cable
associated with it is replaced.

PRELIMINARY
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, calibration, and characterization prior to BTS optimization.
Follow the original equipment manufacture (OEM) recommended
maintenance and calibration schedules closely.
Test Cable Calibration
Equipment test cables are very important in optimization. It is
recommended 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 CDMA
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.
Equipment Warm–up
After arriving at 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:
SCommunications test set.
SRubidium time base.
SPower meter.

Equipment Overview
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 lighter
weight. The BTS is powered by 240 Vac, rectified internally to +27 Vdc,
and can support up to two carriers in a 3–sector configuration. An
SC4812ET Lite starter frame with the maximum of one SC4812ET Lite
expansion frame can support a maximum of four carriers in a 3–sector
configuration. Six–sector operation is not supported with any SC4812ET
Lite configuration.
The BTS frame houses the fan modules, RF compartment heat
exchanger, Small CDMA Channel Processor shelf (SCCP), 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 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.
Logical BTS Numbering
An SC4812ET Lite logical BTS can consist of up to two SC4812ET Lite
frames. In a logical BTS, all frames located at a site are identified as
parts of a single, numbered BTS (for example, BTS–812). Each frame is
assigned a unique frame number. The first, or starter, frame of a logical
BTS has a –1 suffix (for example, BTS–812–1) and the second, or
expansion, frame of the logical BTS is numbered with the suffix, –101
(e. g. BTS–812–101).
Figure 1-1 shows the frame configuration for a logical BTS consisting of
two SC4812ET Lite frames. The figure also shows the BTS–to–CBSC
Transcoder and inter–frame span configurations which can be employed
with an SC4812ET Lite logical BTS.

AC Load Center (ACLC)
The ACLC is the frame entry point for AC power. It incorporates AC
power control, distribution, and surge protection (Figure 1-3).
Back–up Batteries
The batteries (Figure 1-3) provide +24 Vdc back–up for the frame should
AC power be interrupted. The frame can accommodate a total of 12 12V
batteries grouped in six strings. Each string consists of two batteries
connected in series for 24 Vdc output. The six strings are connected in
parallel to meet the current–draw requirements of the frame. The
maximum time duration of the back–up capability depends on system
configuration.
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
or two M–PATH 437 CSU modules which install in the CSU shelf
(Figure 1-3). These modules 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.
Duplexer, Receive filter, Dual Directional Coupler (DRDC)
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 recepticles,
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).
Punchblock
The punchblock (Figure 1-4) is the interface between the frame and the
T1/E1 span lines. It is located on the right–hand side of the power entry
compartment at the rear of the frame. The punchblock provides the
initial interconnection between the spans and the Customer–defined I/O,
alarms, multi–frame timing source (RGPS and RHSO), and pilot beacon
control (optional).

Rectifiers
The rectifiers (Figure 1-3) convert AC power supplied to the frame to
+27.4 Vdc which powers the frame and maintains the charge of the
back–up batteries. Rectifier positions are numbered 1 through 4 from left
to right when facing the frame. Single–carrier frames are equipped with
three rectifiers installed in positions 1, 2, and 3. Two–carrier frames are
equipped with four rectifiers. The number of rectifiers supplied with
each configuration provides N+1 redundancy.
RF Diagnostic Subsystem (RFDS)
The RFDS (Figure 1-5) provides the capability for remotely monitoring
the status of the SC4812ET Lite transmit and receive paths. For
IS–95A/B operation, the RFDS is a COBRA model. To support 1X
operation, the RFDS must the 1X–capable COBRA–II.

SCCP Cage Configuration and
the 1X Devices
SC4812ET Lite frames have one SCCP cage which will support up to 4
MCC cards and 6 BBX cards.
MCC Cards
A BTS may be configured with a mix of MCC–8E, MCC–24, and
MCC–1X cards. Any 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.
BBX Cards
Up to 6 BBX cards of mixed BBX2s and BBX–1Xs can also be
supported. BBX 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 BBX–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 support.

PRELIMINARY
Introduction
This section first verifies proper frame equipage. This includes verifying
module placement, jumper, and dual in–line package (DIP) switch
settings against the site-specific documentation supplied for each BTS
application. Next, pre-power up and initial power-up procedures are
presented.
Cellsite Types
Sites are configured as 3–sector with one or two carriers. Each type has
unique characteristics and must be optimized accordingly.
CDF
The Cell-site Data File (CDF) contains site type and equipage data
information and passes it directly to the CDMA Local Maintenance
Facility (LMF) during optimization. The number of BTS frames, BBX2
and MCC24 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.
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.
CAUTION
Initial Installation of
Boards/Modules
Table 2-1: Initial Installation of Boards/Modules
Step Action
1Refer to the site documentation and, if it was not previously done, slide all boards and modules into
the appropriate shelves as required. DO NOT SEAT the boards and modules at this time.
2As the actual site hardware is installed, record the serial number of each module on a “Serial Number
Checklist” in the site logbook.

Ethernet LAN Termination
For proper operation, each end of the primary and redundant BTS
Ethernet Local Area Networks (LAN) must be terminated with a
50–ohm load. For a BTS consisting of a single frame, this is done by
placing 50–ohm triaxial terminations on the LAN A and B external IN
and OUT connectors located in the power entry compartment
(Figure 2-2). When the LAN links multiple frames in a logical BTS, the
50–ohm triaxial terminations must be installed on all uncabled LAN A
and B external connectors on each frame.
Check the LAN A and B external IN and OUT connectors in the power
entry compartment of each frame, and be sure terminations are installed
on all the uncabled external LAN connectors.

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.
7On the DC PDA, set the MAIN BREAKER to the ON position by pushing it in. Resistance between
the MAP (–) VOLT TEST POINT and the (–) AMP TEST POINT should measure between 300 Ω.

verifying that the locking/retracting tabs appear as follows:
– (in +27 volt systems)
! CAUTION
Using the incorrect type of power/converter modules will damage the module, the SCCP shelf, and
other modules installed in the SCCP shelf.
9* IMPORTANT
In the following steps, if the DMM reads between 300 Ω minimum and 900 Ω maximum after
inserting any board/module, a low impedance problem probably exists in that board/module. Replace
the suspect board/module and repeat the test. If test still fails, isolate the problem before proceeding.
Insert and lock the PS1 DC–DC converter module into its slot, and and turn ON the PS1 DC circuit
breaker on the DC PDA.
10 Resistance between the MAP (–) VOLT TEST POINT and the (–) AMP TEST POINT should
typically increase as capacitors charge, finally measuring between 300 Ω minimum and 900 Ω.

DC Power Application and
Testing
Table 2-6 lists the step–by–step instructions for applying DC power and
ensuring the DC power system components are correctly functioning.
Table 2-6: DC Power Application and Tests
Step Action
1Be sure all DC PDA and battery shelf circuit breakers are OFF (pulled out).
2Be sure the procedures in Table 2-3 (if applicable) and Table 2-5 have been performed.
3! CAUTION
When measuring voltage at the VOLT TEST POINTS, be careful not to short either of the test points
to ground. Failure to comply will result in severe damage to the MAP.
Measure voltage at the MAP VOLT TEST POINTS while pressing the 25° C SET button
(Figure 2-9). The voltage should read 27.4 + 0.2 Vdc. Adjust with the MASTER VOLTAGE ADJ. on
the MAP, if necessary, to obtain an indicated 27.4+0.2 Vdc. Release the 25° C SET button.
4Depending 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 25_C, the voltage will be higher, and if it is
warmer than 25_C, the voltage will be lower.
5Inside the battery compartment, measure the voltage between the cable connection point at the bottom
of the + (red) battery bus bar and chassis ground, observing that the polarity is correct. The voltage
should be the same as the measurement in step 4.
6Measure the voltage between the + (red) and – (black) battery bus bars in the battery compartment.
Place the probe at the bottom of the bus bars where the cables are connected. The DC voltage should
measure the same as in step 4.
7Close (push in) DC PDA MAIN BREAKER.
8On the DC PDA(Figure 2-6), set the PS1 and PS2 circuit breakers to the ON position by pushing
them in one at a time while observing the rectifier output current indicated on the MAP AMP display.
–The display should indicate between 20 and 60 amps.
9On the DC PDA), set the remaining circuit breakers to the ON position by pushing them in one at a
time in the following sequence:
SLPA circuit breakers (four breakers, labeled 1A–1B through 3C–3D).
SHEAT EXCHANGER circuit breakers (two breakers)

10 Confirm that the MAP AMP display continues to indicate between 20 and 60 amps during the initial
power application.
NOTE
No battery charging or heavy RF loading is present at this point.
11 If the frame is not equipped with the pilot beacon option, set the PILOT BEACON circuit breaker
to OFF.
Battery Charge Test
(Connected Batteries)
Table 2-7 lists the step–by–step instructions for testing the battery
charging performance.
Table 2-7: Battery Charge Test (Connected Batteries)
Step Action
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.
2Using the clamp–on DC current probe and DMM, measure the current in each of the battery string
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.

Step Action
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.
5Recheck the DC output voltage. It should remain the same as measured in step 4 of the frame DC
Power Application and Test (Table 2-6).
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.
Battery Discharge Test
Perform the test procedure in Table 2-8 only when the battery current is
less than 5 Amps per string. Refer to Table 2-7 on the procedures for
checking current levels.
Table 2-8: Battery Discharge Test
Step Action
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.
Failure to turn off the MAP BATT TEST switch before
leaving the site will result in low battery capacity and
reduce battery life.

PRELIMINARY
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.
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.
IMPORTANT
*
Optimization Process Overview
After a BTS is physically installed and the preliminary operations, such
as power up, have been completed, the CDMA LMF is used to calibrate
and optimize the BTS. The basic optimization process consists of the
following:
SDownload MGLI2 (GLI2–<bts#>–1) with application code and data
and then enable MGLI2.
SUse the CDMA LMF 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.
SDownload device application code and data to all devices of the
following types:
–CSM2
–BBX2
–Remaining GLI2 (GLI2–<bts#>–2)
–MCC
SDownload the RFDS TSIC (if installed).
SVerify the operation of the GPS and HSO signals.
SEnable the following devices (in the order listed):
–Secondary CSM (slot 2)
–Primary CSM (slot 1)
–All MCCs
SUsing the CDMA LMF test equipment selection function, select the
test equipment to be used for the calibration.
SCalibrate 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. Cable calibration values can be entered
manually, if required.
SConnect the required test equipment for a full optimization.
3
Optimization/Calibration – Introduction – continued
PRELIMINARY
1X SCt4812ET Lite BTS Optimization/ATP 08/01/2001

SSelect 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.
SIf the TX calibration fails, repeat the full optimization for any failed
paths.
SIf the TX calibration fails again, correct the problem that caused the
failure and repeat the full optimization for the failed path.
SIf 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.
Cell Site Types
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 (CDF)
Before using the CDMA 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. Failure to use the
correct CDF files to log into a live (traffic carrying) site
can shut down the site.
IMPORTANT
*
The CDF includes the following information:
SDownload instructions and protocol
SSite specific equipage information
SSCCP shelf allocation plan
–BBX2 equipage (based on cell–site type) including redundancy
–CSM equipage including redundancy
–Multi Channel Card 24 or 8E (MCC24 or MCC8E) channel element
allocation plan. This plan indicates how the SCCP shelf is
configured, and how the paging, synchronization, traffic, and access
channel elements (and associated gain values) are assigned among
the (up to 4) MCC24s or MCC8Es in the shelf.
SCSM equipage including redundancy
SEffective 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 frame antenna connections. The corresponding BBX2
output level required to achieve that power level on any channel/sector
can then be determined based on Bay Level Offset (BLO) data
determined during the optimization process.
Refer to the Figure 3-1 and the LMF Help function for
additional information on the layout of the LMF directory
structure (including CDF file locations and formats).
NOTE
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 LMF Help function, and the LMF Help
function, for more information.
CDF Site Equipage Verification
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.
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.
CAUTION
BTS System Release Software
Download
The System Release software (for example R2.15.x.x) being used by the
Base Station System (BSS) 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. Device application code and data is loaded from the CDMA
LMF computer terminal.

Overview
Before optimization can be performed, the CDMA LMF must be
installed and configured on a computer platform meeting
Motorola–specified requirements (see Recommended Test Equipment
and Software in Chapter 1).
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.
IMPORTANT
*
Software and files for installing and updating the CDMA LMF are
provided on CD ROM disks. The following items must be available:
SCDMA LMF Program on CD ROM
SCDMA LMF Binaries on CD ROM
SConfiguration Data File (CDF) for each supported BTS (on floppy
disk)
SCBSC File for each supported BTS (on floppy disk)
The following section provides information and instructions for
installing and updating CDMA LMF software and files.

NOTE
(If applicable, replace the letter d with the correct CD ROM drive letter.)
5Follow the directions displayed in the Setup screen.
Copy CBSC CDF Files to the
LMF Computer
Before logging on to a BTS with the CDMA 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 CDMA 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 CDMA LMF
computer.
When copying CDF files, comply with the following to
prevent BTS login problems with the Windows LMF:
SThe numbers used in the bts-#.cdf and
cbsc-#.cdf filenames must correspond to the
locally–assigned numbers for each BTS and its
controlling CBSC.
SThe 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.
IMPORTANT
*
The procedure in Table 3-2 lists the steps required to transfer the CDF
files from the CBSC to the CDMA LMF computer. For any further
information, refer to the CDMA LMF Operator’s Guide (Motorola part
no. 68P64114A21) or the CDMA LMF Help screen.

4 Type mount and press the Enter key.
NOTE
SLook for the “floppy/no_name” message on the last line displayed.
SIf 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, where the files to be copied reside, by typing cd <directoryname>
(e.g., cd bts–248) and pressing the Enter key.
6 Type ls and press the Enter key to display the list of files in the directory.
7 With Solaris versions of Unix, create DOS–formatted 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
SOther 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
CDMA LMF computer is, therefore, not recommended.
SUsing 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 CDMA LMF computer.
9When all required files have been copied to the diskette type eject and press the Enter key.
10 Remove the diskette from the CBSC drive.
11 If it is not running, start the Windows operating system on the CDMA LMF computer.
12 Insert the diskette containing the bts–#.cdf and cbsc–#.cdf files into the CDMA LMF computer.
13 Using MS Windows Explorer, create a corresponding bts–# folder in the wlmf\cdma directory for each
bts–#.cdf/cbsc–#.cdf file pair copied from the CBSC.
14 Use MS Windows Explorer to transfer the cbsc–#.cdf and bts–#.cdf files from the diskette to the
corresponding wlmf\cdma\bts–# folders created in step 13.

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 CDMA LMF computer and the FRU. Using features
of the Windows operating system, the connection properties for an MMI
session can be saved on the CDMA 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 3-3 to establish a named HyperTerminal
connection and create a Windows desktop shortcut for it.

Folder Structure Overview
The CDMA LMF uses a wlmf folder that contains all of the essential
data for installing and maintaining the BTS. The following list outlines
the folder structure for CDMA LMF. Except for the bts-nnn folders,
these folders are created as part of the CDMA LMF installation.

data folder
BTS–nnn folders (A separate folder is
required for each BTS where bts–nnn is the
unique BTS number; for example, bts–163.)
wlmf Folder
The wlmf folder contains the CDMA LMF program files.
cdma Folder
The cdma folder contains the bts–nnn folders and the loads folder. It also
contains a default cbsc–1.cdf file that can be copied to a bts–nnn folder
for use, if one cannot be obtained from the CBSC (Centralized Base
Station Controller) when needed.
bts–nnn Folders
Each bts–nnn folder contains a CAL file, a CDF file and a cbsc file for
the BTS. Other files required by CDMA LMF may also be located in the
bts–nnn folder. A bts–nnn folder must be created for each BTS that is to
be logged in to. The bts–nnn folder must be correctly named (for
example: bts–273) and must be placed in the cdma folder. Figure 3-2
shows an example of the file naming syntax for a BTS folder.

cbsc File
The cbsc–#.cdf (Centralized Base Station Controller) file contains data
for the BTS. If one is not obtained from the CBSC, a copy of the default
cbsc–1.cdf file located in the cdma folder can be used.
Using the generic cbsc–1.cdf file will not provide a valid
optimization unless the generic file is edited to replace
default parameters with local operational parameters (e.g.,
CDMA channel numbers must be changed from the default
“384” to those used locally by the BTS).
IMPORTANT
*
loads Folder
The loads folder contains the version folder(s). It does not contain any
files.
version Folder
The version folder(s) contains the code and data folders. It does not
contain any files. The name of version folders is the software version
number of the code files that are included in its code folder. Version
folders are created as part of the CDMA LMF installation and CDMA
LMF updates. Each time the CDMA LMF is updated, another version
folder will be created with the number of the software version for the
code files being installed.
code Folder
The code folder contains the binary files used to load code into the
devices. A unique binary code file is required for each device type in the
BTS to be supported with the CDMA LMF. Current version code files
for each supported device created in this folder from the CDMA LMF
CD ROM as part of the CDMA LMF installation/update process.
Figure 3-5 shows an example of the file naming syntax for a code load
file.

Span Lines – Interface and Isolation
PRELIMINARY
1X SCt4812ET Lite BTS Optimization/ATP 08/01/2001
3-14
T1/E1 Span Interface
At active sites, the OMC–R/CBSC must disable the BTS
and place it out of service (OOS). DO NOT remove the
span line cable conectors until the OMC–R/CBSC has
disabled the BTS.
IMPORTANT
*
Each frame is equipped with one 50–pair punchblock for spans,
customer alarms, remote GPS, and BTS frame alarms. See Figure 3-9
and refer to Table 3-5 for the physical location and punchdown location
information.
Before connecting the LMF computer to the frame LAN, the
OMC–R/CBSC must disable the BTS and place it OOS to allow the
LMF to control the BTS. This prevents the CBSC from inadvertently
sending control information to the BTS during LMF–based tests.
Isolate BTS from T1/E1 Spans
Once the OMC–R/CBSC has disabled the BTS, the spans must be
disabled to ensure the LMF will maintain control of the BTS. To disable
the spans, disconnect the cable connector for the BTS–to–CBSC
Transcoder span at the Span I/O card (Figure 3-7).
If the BTS is a multi–frame logical BTS, do not disconnect
the inter–frame span.

Configure Optional Channel
Service Units
The M–PATH 537 Channel Service Unit (CSU) module provides
in–band SNMP–managed digital service access to T1 and fractional T1
lines. The M–PATH 437 Channel Service Unit (CSU) module provides
in–band SNMP–managed digital service access to E1 and fractional E1
lines. CSU modules units plug into the CSU shelf (see Figure 3-8).
The CSU shelf can support two M–PATH 537 or two M–PATH 437 CSU
modules. The 537 CSU module supports a single T1 span connection.
The 437 CSU module supports a single E1 span connection.
Remote M–PATH management is available via SNMP over an in–band
data link on the span 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.
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 are supplied with each unit.
For more information refer to M–PATH T1 Channel Service Unit User’s
Guide, ADC Kentrox part number 65–77538101 or the M–PATH E1
Channel Service Unit User’s Guide, ADC Kentrox part number TBD.
Setting the Control Port
Whichever control port is chosen, it must first be configured so the
control port switch settings 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.” If using the rear–panel DCE
control port, position the SHELF ADDRESS switch down.
For more information, refer to the 2–Slot Universal Shelf Installation

LMF to BTS Connection
The CDMA LMF computer may be connected to the LAN A or B
connector located behind the frame lower air intake grill. Figure 3-10
below shows the general location of these connectors. LAN A is
considered the primary LAN.
Table 3-6: Connect the LMF to the BTS
Step Action
1To gain access to the LAN connectors, open the LAN cable and utility shelf access panel, then pull
apart the hook–and–loop fabric covering the BNC “T” connector (see Figure 3-10). If desired, slide
out the utility shelf for the LMF computer.
2Connect the CDMA LMF computer to the LAN A (left–hand) BNC connector via PCMCIA Ethernet
Adapter.
NOTE
Xircom Model PE3–10B2 or equivalent can also be used to interface the CDMA LMF Ethernet
connection to the BTS frame connected to the PC parallel port, powered by an external AC/DC
transformer. In this case, the BNC cable must not exceed three feet 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.

Using CDMA LMF
08/01/2001 3-21
1X SCt4812ET Lite BTS Optimization/ATP
PRELIMINARY
Basic CDMA LMF Operation
The CDMA LMF allows the user to work in the two following operating
environments which are accessed using the specified desktop icons:
SGraphical User Interface (GUI) using the WinLMF icon
SCommand 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 CDMA LMF in either environment includes
performing the following:
SSelecting and Deselecting BTS devices
SEnabling devices
SDisabling devices
SResetting devices
SObtaining device status
The following additional basic operation can be performed in a GUI
environment:
SSorting a status report window
For detailed information on performing these and other CDMA LMF
operations, refer to the LMF Help function and the LMF CLI Reference;
68P09253A56.
Unless otherwise noted, LMF procedures in this manual
are performed using the GUI environment.
IMPORTANT
*
CDMA LMF and Logical BTS
An SC4812ET Lite logical BTS can consist of up to two SC4812ET Lite
frames. When the CDMA LMF is connected to a frame 1 Ethernet port
of a logical BTS, access is available to all devices in all of the frames
that make up the logical BTS. A logical BTS CDF file that includes
equipage information for all of the logical BTS frames and their devices
is required for proper LMF interface. A CBSC CDF file that includes
channel data for all of the logical BTS frames is also required.
The first frame of a logical BTS has a –1 suffix (for example,
BTS–812–1) and the second frame of the logical BTS is numbered with
the suffix, –101 (e. g. BTS–812–101). When the CDMA LMF is logged
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
3

PRELIMINARY

separate FRAME tab for each frame(for example, FRAME–438–1, and
FRAME–438–101 for BTS–438 that has both frames). If an RFDS is
included in the CDF file, an RFDS tab (e.g., RFDS–438–1) will be
displayed.
Actions, such as ATP tests, can be initiated for selected devices in one or
more frames of a logical BTS. Refer to the CDMA LMF Select devices
help screen for information on how to select devices.
Logging Into a BTS
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.
CAUTION
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 CDMA LMF may be logged into each BTS.
Before attempting to start the CDMA LMF computer and the CDMA
LMF software, confirm the CDMA LMF computer is properly connected
to the BTS (see Table 3-6). Follow the procedures in Table 3-7 to log
into a BTS.
Prerequisites
Before attempting to log into a BTS, ensure the following have been
completed:
SThe CDMA LMF is correctly installed and prepared.
SA bts-nnn folder with the correct CDF and CBSC files exists.
SThe CDMA LMF computer was connected to the BTS before starting
the Windows operating system and the CDMA LMF software. If
necessary, restart the computer after connecting it to the BTS in
accordance with Table 3-6 and Figure 3-10.
