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.”
1
Assumptions and Prerequisites
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.
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
Why Optimize?
What Is Optimization?
What Happens During
Optimization
1
Proper optimization and calibration ensures that:
S Accurate downlink RF power levels are transmitted from the site.
S Accurate uplink signal strength determinations are made by the site.
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.
Optimization identifies the accumulated loss (or gain) for each receive
and transmit path at the BTS site, and stores these values in a database.
S A 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.
S A 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
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
Periodic Optimization
Repaired Sites
Optimization is also required after expansion of a site with additional,
interconnected BTS frames.
Periodic optimization of a site may also be required, depending on the
requirements of the overall system.
IMPORTANT

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.

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, calibration, and characterization prior to BTS optimization.
Follow the original equipment manufacture (OEM) recommended
maintenance and calibration schedules closely.
1
Test Cable Calibration
Equipment Warm–up
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.
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:
S Communications test set.
S Rubidium time base.
S Power meter.

BTS Equipment Identification
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.

Internal Assembly Location and Identification – continued
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.
1
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.
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.

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

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.

Table 1-5: Sector Configurations
ConfigurationDescription
3–Sector / 1 Carrier
The configuration below maps RX and TX with bandpass filters for a 3–sector/1–carrier frame.
This section first verifies proper frame equipage. This includes verifying
module placement, jumper, and dual in–line package (DIP) switch
settings against the site-specific documentation supplied for each BTS
application. Next, pre-power up and initial power-up procedures are
presented.
Sites are configured as 3–sector with one or two carriers. Each type has
unique characteristics and must be optimized accordingly.
The Cell-site Data File (CDF) contains site type and equipage data
information and passes it directly to the 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.
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 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.

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.

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.

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.

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:
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.
S Download MGLI2 (GLI2–<bts#>–1) with application code and data
and then enable MGLI2.
S Use 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.
S Download device application code and data to all devices of the
S Using the CDMA LMF test equipment selection function, select the
test equipment to be used for the calibration.
S Calibrate the TX and RX test cables if they have not previously been
calibrated using the CDMA LMF that is going to be used for the
optimization/calibration. Cable calibration values can be entered
manually, if required.
S Connect the required test equipment for a full optimization.

Optimization/Calibration – Introduction– continued
S 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.
S If the TX calibration fails, repeat the full optimization for any failed
paths.
S If the TX calibration fails again, correct the problem that caused the
failure and repeat the full optimization for the failed path.

S 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.
IMPORTANT
*
The CDF includes the following information:
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.

documentation. Use a text editor to view the CDF contents.
CAUTION
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.

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

Copy CBSC CDF Files to the
LMF Computer
Table 3-1: CD ROM Installation
3
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.
IMPORTANT
*
When copying CDF files, comply with the following to
prevent BTS login problems with the Windows LMF:
S 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.
S 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.
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.

Use the explicit floppy/no_name reference displayed when performing step 7.
S 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
CDMA LMF computer is, therefore, not recommended.
S 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).

Creating a Named
HyperTerminal Connection for
MMI Communication
Table 3-3: Create HyperTerminal Connection
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

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.

bts–nnn Folders
08/01/2001
The wlmf folder contains the CDMA LMF program files.
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.
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.

loads Folder
version Folder
code Folder
*
The loads folder contains the version folder(s). It does not contain any
files.
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.
Using the generic cbsc–1.cdf file will not provide a validoptimization 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).

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.
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).
*
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
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

CDMA LMF and Logical BTS
08/01/2001
*
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

Logging Into a BTS
CAUTION
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 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:
3-22
S The CDMA LMF is correctly installed and prepared.
S A bts-nnn folder with the correct CDF and CBSC files exists.
S The 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.
