General Safety
July 1999 xv
SC 4812ET BTS Optimization/ATP – CDMA LMF
PRELIMINARY 2
Remember! . . . Safety
depends on you!!
The following general safety precautions must be observed during all
phases of operation, service, and repair of the equipment described in
this manual. Failure to comply with these precautions or with specific
warnings elsewhere in this manual violates safety standards of design,
manufacture, and intended use of the equipment. Motorola, Inc. assumes
no liability for the customer’s failure to comply with these requirements.
The safety precautions listed below represent warnings of certain dangers
of which we are aware. You, as the user of this product, should follow
these warnings and all other safety precautions necessary for the safe
operation of the equipment in your operating environment.
Ground the instrument
To minimize shock hazard, the equipment chassis and enclosure must be
connected to an electrical ground. If the equipment is supplied with a
three-conductor ac power cable, the power cable must be either plugged
into an approved three-contact electrical outlet or used with a
three-contact to two-contact adapter. The three-contact to two-contact
adapter must have the grounding wire (green) firmly connected to an
electrical ground (safety ground) at the power outlet. The power jack and
mating plug of the power cable must meet International Electrotechnical
Commission (IEC) safety standards.
Do not operate in an explosive
atmosphere
Do not operate the equipment in the presence of flammable gases or
fumes. Operation of any electrical equipment in such an environment
constitutes a definite safety hazard.
Keep away from live circuits
Operating personnel must:
Snot remove equipment covers. Only Factory Authorized Service
Personnel or other qualified maintenance personnel may remove
equipment covers for internal subassembly, or component
replacement, or any internal adjustment.
Snot replace components with power cable connected. Under certain
conditions, dangerous voltages may exist even with the power cable
removed.
Salways disconnect power and discharge circuits before touching them.
Do not service or adjust alone
Do not attempt internal service or adjustment, unless another person,
capable of rendering first aid and resuscitation, is present.

Use caution when exposing or
handling the CRT
Breakage of the Cathode–Ray Tube (CRT) causes a high-velocity
scattering of glass fragments (implosion). To prevent CRT implosion,
avoid rough handling or jarring of the equipment. The CRT should be
handled only by qualified maintenance personnel, using approved safety
mask and gloves.
Do not substitute parts or
modify equipment
Because of the danger of introducing additional hazards, do not install
substitute parts or perform any unauthorized modification of equipment.
Contact Motorola Warranty and Repair for service and repair to ensure
that safety features are maintained.
Dangerous procedure
warnings
Warnings, such as the example below, precede potentially dangerous
procedures throughout this manual. Instructions contained in the
warnings must be followed. You should also employ all other safety
precautions that you deem necessary for the operation of the equipment
in your operating environment.

SC 4812ET BTS Optimization/ATP – CDMA LMF
PRELIMINARY 2
Scope of This Document
This document provides information pertaining to the optimization and
audit tests of Motorola SC 4812ET Base Transceiver Subsystem (BTS)
equipment frames equipped with trunked high–power Linear Power
Amplifiers (LPAs) and their associated internal and external interfaces.
This document assumes the following prerequisites: The BTS frames
and cabling have been installed per the BTS Hardware Installation Manual
– 68P64114A22, which covers the physical “bolt down” of all SC series
equipment frames, and the specific cabling configurations.
Document Composition
This document covers the following major areas:
SIntroduction, consisting of preliminary background information (such
as component and subassembly locations and frame layouts) to be
considered by the Cell Site Field Engineer (CFE) before optimization
or tests are performed.
SPreliminary Operations, consisting of Cabinet Power Up and Power
Down Procedures.
SOptimization/calibration, covering topics of LMF connection to the
BTS equipment, GPS Verification, Test equipment setup,
downloading all BTS processor boards, RF path verification, BLO
calibration and calibration audit, and Radio Frequency Diagnostic
System (RFDS) calibration.

CDMA LMF Product Description
CDMA LMF is a graphical user interface (GUI) based Local
Maintenance Facility(LMF). This product is specifically designed to
provide cellular communications field personnel the vehicle to support
the following CDMA Base Transceiver Stations (BTS) operations:
SInstallation
SMaintenance
SCalibration
SOptimization
Online Help
Task oriented online help is available in the LMF by clicking on Help
from the menu bar.
Why Optimize?
Proper optimization and calibration assures:
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. Cables that interconnect the BTS and Duplexer
assemblies (if used), for example, are cut and installed at the time of the
BTS frame installation at the site. Site optimization guarantees that the
combined losses of the new cables and the gain/loss characteristics and
built-in tolerances of each BTS frame do not accumulate, causing
improper site operation.
Optimization identifies the accumulated loss (or gain) for all receive and
transmit paths at the BTS site, and stores that value in a database.
SRX path starts at the ancillary equipment frame RFDS RX directional
coupler antenna feedline port, through the RX input port on the rear of
the frame, through the DDRCs, Multicoupler Preselector Card (MPC),
and additional splitter circuitry, ending at a Code Division Multiple
Access (CDMA) Channel Processor (C–CCP) backplane Broad Band
Transceiver (BBX2) slot in the C–CCP shelf.
SA transmit path starts at the BBX2, through the C–CCP backplane
slot, travels through the LPA/Combiner TX Filter and ends at the rear
of the input/output (I/O) Panel. If the RFDS option is added, then the
TX path continues and ends at the top of the RFDS TX directional
coupler antenna feedline port installed in the ancillary equipment
frame.
These values are factored in by the BTS equipment internally, leaving
only site specific antenna feed line loss and antenna gain characteristics
to be factored in by the CFE when determining site Effective Radiated
Power (ERP) output power requirements.

SC 4812ET BTS Optimization/ATP – CDMA LMF
PRELIMINARY 2
Each C–CCP shelf BBX2 board is optimized to a specific RX and TX
antenna port. (One BBX2 board acts in a redundant capacity for BBX2s
1–12, and is optimized to all antenna ports). A single value is generated
for each path, thereby eliminating the accumulation of error that would
occur from individually measuring and summing the gain and loss of
each element in the path.
When to Optimize
New Installations
After the initial site installation, the BTS must be prepared for operation.
This preparation includes verifying hardware installation, initial power
up, and GPS verification. Basic alarm tests are also addressed.
A calibration audit of all RF transmit paths is performed to verify factory
calibration.
A series of ATP CDMA verification tests are covered using the actual
equipment set up. An Acceptance Test Procedure (ATP) is also required
before the site can be placed in service.
Site Expansion
Optimization is also required after expansion of a site.
Periodic Optimization
Periodic optimization of a site may also be required, depending on the
requirements of the overall system.
Repaired Sites
Verify repair(s) made to the BTS by consulting an Optimization/ATP
Test Matrix table. This table outlines the specific tests that must be
performed anytime a BTS subassembly or RF cable associated with it is
replaced.
Refer to Appendix B for detailed basic guideline tables and
detailed Optimization/ATP Test Matrix.

optimize the BTS equipment. You can, of course, substitute test
equipment with other test equipment models supported by the local
maintenance facility (LMF) meeting the same technical specifications.
LMF Hardware Requirements
An LMF computer platform that meets the following requirements (or
better) is recommended:
SNotebook computer
S266 MHz (32 bit CPU) Pentium processor
S4 Gbyte internal hard disk drive
SColor display with 1024 x 768 (recommended) or 800 x 600 pixel
resolution
S64 MB RAM
SCD ROM drive
S3 1/2 inch floppy drive
SSerial port (COM 1)
SParallel port (LPT 1)
SPCMCIA Ethernet interface card (for example, 3COM Etherlink III)
with a 10Base–T–to–coax adapter
SWindows 98/NT operating system
If 800 x 600 pixel resolution is used, the CDMA LMF
window must be maximized after it is displayed.
NOTE
Required Test Equipment
To ensure consistent, reliable, and repeatable optimization test results,
test equipment meeting the following technical criteria should be used to
optimize the BTS equipment. You can, of course, substitute test
equipment with other test equipment models supported by the LMF
meeting the same technical specifications.
During manual testing, you can substitute test equipment
with other test equipment models not supported by the
LMF, but those models must meet the same technical
specifications.
NOTE
The customer has the responsibility of accounting for any measurement
variances and/or additional losses/inaccuracies that can be introduced
as a result of 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 manufacturer (OEM) recommended
maintenance and calibration schedules closely.
Test Cable Calibration
Equipment test cables are very important in optimization. Motorola
recommends that the cable calibration be run at every BTS with the test
cables attached. This method compensates for test cable insertion loss
within the test equipment itself. No other allowance for test cable
insertion loss needs to be made during the performance of tests.
Another method is to account for the loss by entering it into the LMF
during the optimization procedure. This method requires accurate test
cable characterization in a shop. The cable should be tagged with the
characterization information prior to field optimization.
Equipment Warm–up
After arriving at the a site, the test equipment should be plugged in and
turned on to allow warm up and stabilization to occur for as long as
possible. The following pieces of test equipment must be warmed–up for
a minimum of 60 minutes prior to using for BTS optimization or Radio
Frequency Diagnostic Subsystem (RFDS) calibration procedures.
SCommunications Test Set
SRubidium Time Base
SPower Meter
Test Equipment List
The following pieces of test equipment are required during the
optimization procedure. Common assorted tools like screwdrivers and
frame keys are not listed but are still required. Read the owner’s manual
on all of the following major pieces of test equipment to understand their
individual operation prior to use in optimization.
Always refer to specific OEM test equipment
documentation for detailed operating instructions.

Station Controller (CBSC) and the site antennas. This frame is described
in three sections:
SThe I/O interconnect plate where all connections are made is located at
the back of the BTS.
SThe RF section of the frame which houses the circuit breakers, cooling
fans, the Combined CDMA Channel Processor (C–CCP) shelf, the
duplexors, filters, RFDS and CSU.
SThe LPA compartment which houses the LPAs and blower assembly.
Use the illustrations that follow to visually identify the major
components, that make up the Motorola SC 4812ET BTS frame.

Sector Configuration
There are a number of ways to configure the BTS frame. Table 1-2
outlines the basic requirements. When carrier capacity is greater than
two, a 2:1 or 4:1 cavity combiner must be used. For one or two carriers,
bandpass filters or cavity combiners may be used, depending on
sectorization and channel sequencing.

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 with a maximum of 4 carriers, 3–sectored with a
maximum of 4 carriers, and 6–sectored with a maximum of 2 carriers.
Each type has unique characteristics and must be optimized accordingly.
For more information on the differences in site types, please refer to the
BTS/Modem Frame Hardware Installation manual.
CDF
The Cell-site Data File (CDF) contains site type and equipage data
information and passes it directly to the LMF during optimization. The
number of modem frames, C–CCP shelves, BBX2 and MCC24/MCC8E
boards (per cage), 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 BTS or Modem frame and
ancillary equipment frame.
Always wear a conductive, high impedance wrist strap
while handling any circuit card/module to prevent damage
by ESD. After removal, the card/module should be placed
on a conductive surface or back into the anti–static 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 install all boards and modules into the appropriate shelves as
required. Verify they are NOT SEATED 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.

SC 4812ET BTS Optimization/ATP – CDMA LMF
PRELIMINARY 2
Introduction
This section of the manual contains instructional information on the
proper power up procedure for the SC 4812ET BTS. Also presented in
this chapter is the Optimization/ATP tests to be preformed on the Power
cabinet. Please pay attention to all Cautions and Warning statements in
order to prevent accidental injury to personnel.
The following tools are used in the Power Cabinet Power Up procedures.
Required Tools
SDigital Voltmeter
SDC current clamp (600 Amp capability with jaw size to accommodate
2/0 cable).
SHot Air Gun – (optional for part of the Alarm Verification)
Initial Inspection and Setup
Ensure all battery breakers for unused battery positions are
open (pulled out) during any part of the power up process,
and remain in the off position when leaving the site.
CAUTION
Verify that ALL AC and DC breakers are turned OFF in the Power
cabinet. Verify all DC circuit breakers are OFF in the RF cabinet. Verify
that the DC power cables between the Power and RF cabinets are
connected with the correct polarity
The RED cables connect to the uppermost three (3) terminals (marked
+) in both cabinets. Confirm that the split phase 240/120 AC supply is
correctly connected to the AC load center input.
Failure to connect the proper AC feed will damage the
surge protection module inside the AC load center.
CAUTION
Power Up Sequence
The first task in the power up sequence is to apply AC power to the
Power cabinet. Once power is applied a series of AC Voltage
measurements is required.
Table 2-2: AC Voltage Measurements
Step Action
1Measure the AC voltages connected to the AC load center (access the terminals from the rear of
the cabinet after removing the AC load center rear panel).
2Measure the AC voltage from terminal L1 to neutral. This voltage should be in the range of
nominally 115 to 120 V AC.

Table 2-2: AC Voltage Measurements
Step Action
3Measure the AC voltage from terminal L1 to ground. This voltage should be in the range of
nominally 115 to 120 V AC.
4Measure the AC voltage from terminal L2 to neutral. This voltage should be in the range of
nominally 115 to 120 V AC.
5Measure the AC voltage from terminal L2 to ground. This voltage should be in the range of
nominally 115 to 120 V AC.
If the AC voltages are in excess of 120 V (or exceed 200
V) when measuring between terminals L1 or L2 to neutral
or ground, STOP and Do Not proceed until the cause of
the higher voltages are determined. The power cabinet
WILL be damaged if the Main breaker is turned on with
excessive voltage on the inputs.
CAUTION
When the input voltages are verified as correct, turn the Main AC
breaker (located on the front of the AC Load Center) ON. Observe that
all eight (8) green LEDs on the front of the AC Load Center are
illuminated.
Turn Rectifier 1 and Rectifier 2 AC branch breakers (on the AC Load
Center) ON. All the installed rectifier modules will start up and should
each have two green LEDs (DC and Power) illuminated.
Turn the DMAC (Digital Metering and Alarms Control) module, ON
while observing the K2 contact in the PDA assembly. The contact should
close. The DMAC voltage meter should read approximately 27.4 + 0.2
VDC.
Turn the TCP (Temperature Control Panel) ON, .The DMAC should not
be have any alarm LEDs illuminated .
Check the rectifier current bargraph displays. None should be
illuminated at this point.
If batteries are fitted, turn on the two battery heater AC
breakers on the AC Load Center.

PRELIMINARY 2
Power Up Tests
Table 2-3 lists the step–by–step instructions for Power Up Tests.
Table 2-3: Power Up Tests
Step Action
1Probe the output voltage test point on the DMAC while pressing the 25° C set button on the TCP.
The voltage should read 27.4 + 0.2 VDC. Adjust Master Voltage on DMAC if necessary. Release
the TCP 25° C set button.
2Depending 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.
3Close the three (3) Main DC breakers on the Power Cabinet ONLY. Close by holding in the reset
button on the front of the PDA, and engaging one breaker at a time.
4Measure the voltage between the + and – terminals at the rear of the Power Cabinet and the RF
Cabinet, observing that the polarity is correct. The voltage should be the same as the measurement
in step 2.
5Place the probes across the black and red battery buss bars in each battery compartment. Place the
probe at the bottom of the buss bars where the cables are connected. The DC voltage should
measure the same as the previous step.
Battery Charge Test
Table 2-4 lists the step–by–step instructions for testing the batteries.
Table 2-4: Battery Charge Test
Step Action
1Close the battery compartment breakers for connected batteries ONLY. This process should be
completed quickly to avoid individual battery strings with 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 is observed, turn off the DMAC power switch, and then
engage all the connected battery circuit breakers, the DMAC power switch should then be turned
on.
2Using the DC current probe, measure the current in each of the battery string connections to the
buss bars in each battery cabinet. The charge current may initially be high but should quickly
reduce in a few minutes if the batteries have a typical new battery charge level.
3The current in each string should be approximately equal (+ 5 amps).

Table 2-4: Battery Charge Test
Step Action
4The bargraph meters on the rectifier modules can be used as a rough estimate of the total battery
charge current. Each rectifier module has eight (8) LEDs to represent the output current. Each
illuminated LED indicates that approximately 12.5% (1/8 or 8.75 Amps) of the rectifiers
maximum (70 Amps) current is flowing.
EXAMPLE:
Question: A system fitted with three (3) rectifier modules each have three bargraph LEDs
illuminated. What is the total output current into the batteries?
Answer: Each bargraph is approximately indicating 12.5% of 70 Amps, therefore, 3 X 8.75 equals
26.25 Amps. As there are three rectifiers, the total charge current is equal to (3 X 26.25 A) 78.75
Amps.
This charge current calculation only applies at this part of the start up procedure, when the RF
Cabinet is not powered on, and the power cabinet heat exchanger is turned off.
5Allow 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 5A.
6Recheck the DC output voltage. It should remain the same as measured in step 4 of the Power Up
Test.
NOTE
If discharged batteries are installed, all bargraphs may be illuminated on the rectifiers during the
charge test. This indicates that the rectifiers are at full capacity and are rapidly charging the
batteries. It is recommended in this case that the batteries are allowed to charge and stabilize as in
the above step before commissioning the site. This could take several hours.
RF Cabinet Power Up
Table 2-5 covers the procedures for properly powering up the RF
Cabinet.
Table 2-5: RF Cabinet Power Up
Step Action
1Turn the 400 Amp Main DC breaker in the RF Cabinet ON.
NOTE
Ensure that no alarms or voltage change has occurred in the power cabinet, and that the power
cabinet Main DC breakers have not tripped. The rectifier bargraph readings should be the same as
before the main breaker in the RF cabinet was turned ON.
2Proceed to RF cabinet power up sequence.

4Measure the voltage drop between the Power Cabinet meter test point and the 27 V buss bar inside
the RF Cabinet PDA while the RF Cabinet is transmitting.
NOTE
For a three (3) sector carrier system, the voltage drop should be less than 0.2 VDC.
For a twelve (12) sector carrier system, the voltage drop should be less than 0.3 VDC.
5Using a DC current probe, measure the current in each of the six (6) DC cables that are connected
between the RF and Power Cabinet. The DC current measured should be approximately the same.
If there is a wide variation between one cable and the others (>10 A), check the tightness of the
connections (torque settings) at each end of the cable.
Battery Discharge Test
The test procedures in Table 2-6 should only be performed when the
battery current is less than 5 A per string. Refer to Table 2-4 on the
procedures for checking current levels.

Alarm Verification
The alarms test should be performed at a convenient point in the RF
Cabinet ATP procedure, since an LMF is necessary to ensure that the RF
Cabinet is receiving the appropriate alarms from the Power Cabinet.
The SC 4812ET is capable of concurrently monitoring 10 customer
defined input signals and four customer defined outputs, which interface
to the 50–pin punchblock. All alarms are defaulted to “Not Equipped”
during ATP testing. Testing of these inputs is achieved by triggering the
alarms and monitoring the LMF for state–transition messages from the
active MGLI2.
All customer alarms are routed through the 50 pair punchblock located
in the I/O compartment at the back of the frame. Testing is best
accomplished by using a specialized connector that interfaces to the
50–pair punchblock. This connector is wired so that customer return 1 (2
for the B side) is connected to every input, CDI 0 through CDI 17.

DC Power Pre-test (BTS Frame) Before applying any power to the BTS cabinet, follow the steps outlined
in Table 2-18 while referring to Figure 2-2 to verify there are no shorts in
the RF or Power Cabinet’s DC distribution system.
Table 2-18: DC Power Pre–test (RF Cabinet and Power Cabinet)
Step Action
1Physically verify that all DC/DC converters supplying power to the cabinets are OFF or disabled.
2On each RF cabinet:
SUnseat all circuit boards/ modules in the distribution shelf, transceiver shelf, and Single Carrier
Linear Power Amplifier (SCLPA) shelves, but leave them in their associated slots.
SUnseat all circuit boards (except CCD and CIO cards) in the C–CCP shelf and LPA shelves, but
leave them in their associated slots.
SSet C–CCP shelf breakers to the OFF position by pulling out power distribution breakers (labeled
C–CCP 1, 2, 3 – located on the power distribution panel).
SSet LPA breakers to the OFF position by pulling out power distribution breakers (8 breakers,
labeled 1A–1B through 4C–4D – located on the power distribution panel).
–1A through 3B – ELPA breakers (earlier model breaker panel – use breakers 1 through 24)
3Verify that the resistance from the power (+ or –) feed terminals with respect to the ground terminal on
the cabinet measures > 500 Ω.
SIf reading is < 500 Ω, a short may exist somewhere in the DC distribution path supplied by the
breaker. Isolate the problem before proceeding. A reading > 3 MΩ could indicate an open (or
missing) bleeder resistor (installed across the filter capacitors behind the breaker panel).
4Set the C–CCP breakers (C–CCP 1, 2, 3) to the ON position by pushing them IN one at a time.
Repeat step 3 after turning on each breaker.
* IMPORTANT
If, after inserting any board/module, the ohmmeter stays at 0 Ω, a short probably exists in that
board/module. Replace the suspect board/module and repeat the test. If test still fails, isolate the
problem before proceeding.
5Insert and lock the DC/DC converter modules into their associated slots one at a time. Repeat step 3
after inserting each module.
SA typical response is that the ohmmeter will steadily climb in resistance as capacitors charge, finally
indicating approximately 500 Ω.
! CAUTION
Verify the correct power/converter modules by observing the locking/retracting tabs appear as follows:
– (in +27 volt systems)
6Insert and lock all remaining circuit boards and modules into their associated slots in the C–CCP shelf.
Repeat step 3 after inserting and locking each board or module.
SA typical response is that the ohmmeter will steadily climb in resistance as capacitors charge,
stopping at approximately 500 Ω..

Optimization/Calibration – Introduction
July 1999 3-1
SC 4812ET BTS Optimization/ATP – CDMA LMF
PRELIMINARY 2
Introduction
This section describes procedures for downloading system operating
software, set up of the supported test equipment, CSM reference
verification/optimization, and transmit/receive path verification.
Cell–site Types
Sites are configured as Omni/Omni or Sector/Sector (TX/RX). Each type
has unique characteristics and must be optimized accordingly.
For more information on the differences in site types,
please refer to the applicable BTS/Modem Frame Hardware
Installation and Functional Hardware Description
manuals.
NOTE
Cell–site Data File (CDF)
The CDF includes the following information:
SDownload instructions and protocol
SSite specific equipage information
SC–CCP shelf allocation plan
– BBX2 equipage (based on cell–site type) including redundancy
– CSM equipage including redundancy
– Multi Channel Card 24 (MCC24 or MCC8E) channel element
allocation plan. This plan indicates how the C–CCP shelf is
configured, and how the paging, synchronization, traffic, and access
channel elements (and associated gain values) are assigned among
the (up to 12) 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 top of the BTS frame. The corresponding BBX2 output
level required to achieve that power level on any channel/sector can
also be determined.
Refer to the CDMA Operator’s Guide, 68P64114A21, for
additional information on the layout of the LMF directory
structure (including CDF file locations and formats).

BTS System Software
Download
BTS system software must be successfully downloaded to the BTS
processor boards before optimization can be performed. BTS operating
code is loaded from the LMF computer terminal. Before you can log
into a site, the LMF must have a BTS folder for that site. Whenever
there is a new release of BTS system software (binaries), it must first be
loaded on the LMF from a CD–ROM before it can be downloaded to the
BTS. The CDF is normally obtained from the CBSC on a floppy disk or
through a file transfer protocol (ftp) if the LMF computer has the
capability.
Site Equipage Verification
If you have not already done so, use an LMF to view the CDF, and
review the site documentation. Verify the site engineering equipage data
in the CDF to the actual site hardware.
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.

Isolate BTS from T1/E1 Spans
–At active sites, the OMC/CBSC must disable the
BTS and place it out of service (OOS). DO NOT
remove the span surge protectors until the
OMC/CBSC has disabled the BTS!
IMPORTANT
*
Each frame is equipped with one 50 pair punchblock for spans, customer
alarms, remote GPS, and power cabinet alarms (see Figure 3-1 and
Table 3-1). To disable the span, pull out the surge protectors for the
respective span.
Before connecting the LMF to the frame LAN, the OMC/CBSC must
disable the BTS and place it OOS to allow the LMF to control the
CDMA BTS. This prevents the CBSC from inadvertently sending
control information to the CDMA BTS during LMF based tests.
Alarm and Span Line Cable
Pin/Signal Information
Table 3-1 lists the complete pin/signal identification for the 50–pin
punch block.
Channel Service Unit
The channel service unit (CSU) contains a modular Eternet jack on its
fron panel, allowing Eternet UP access to CSUs installed in the same
shelf Each 19 inch rack can support two CSU (M–PATH 538) modules.
Each module supports one span connection. Programming of the CSU is
accomplished through the DCE 9–pin connector on the front panel.

File
The CDF file contains data that defines the BTS and data that is used to
download data to the devices. A CDF file must be placed in the
applicable BTS folder before the LMF can be used to log into that BTS.
CDF files are normally obtained from the CBSC using a floppy disk. A
file transfer protocol (ftp) method can be used if the LMF computer has
that capability. Figure 3-6 shows the file name syntax for the CDF file.

Graphical User Interface
Overview
This section provides overview information on using the LMF graphical
user interface (GUI). The GUI works as follows:
SSelect the device or devices to perform an action on.
SSelect the action to apply to the selected device(s).
SWhile action is in progress, a status report window displays the action
taking place and other status information.
SThe status report window indicates when the the action is complete,
along with other pertinent information displayed.
SClicking the OK button closes the status report window.
The R9 BTS software release implements the virtual BTS capability,
also known as Logical BTS. A virtual BTS can consist of up to four
four SC 4812ET frames. When the LMF is connected to frame 1 of a
virtual BTS, you can access all devices in all of the frames that make up
the virtual BTS A virtual BTS CDF file that includes equippage
information for all of the virtual BTS frames and their devices is
required. A CBSC file that includes channel data for all of the virtual
BTS fames is also required. The first frame of a virtual BTS has a –1
suffix (e.g., BTS–812–1) and other frames of the virtual BTS are
numbered with suffixed, –101, –201, and –301 (e. g. BTS–812–201).
When you log into a BTS a FRAME tab is displayed for each frame. If
there is only one frame for the BTS, there will only be one tab (e.g.,
FRAME–282–1) for BTS–282. If a virtual BTS has more than one
frame, there will be a separate FRAME tab for each frame (e.g.
FRAME–438–1, FRAME–438–101, and FRAME–438–202 for a
BTS–438 that has all three frames). If an RFDS is included in the CDF
file, an RFDS tab (e.g., RFDS–438–1) will be displayed.
Actions (e.g., ATP tests) can be initiated for selected devices in one or
more, frames of a virtual BTS. Refer to the Select devices help screen
for information on how to select devices.
Following are visual examples of the BTS tabs for a single–frame BTS
with RFDS and a four–frame BTS with RFDS.

Enable CSMs
Each BTS CSM system features two CSM boards per site. The GPS
receiver (mounted on CSM 1) is used as the primary timing reference
and synchronizes the entire cellular system. CSM 2 provides redundancy
(but does not have a GPS receiver).
The BTS may be equipped with a LORAN–C Low Frequency Receiver
(LFR), or external 10 MHz Rubidium source which the CSM can use as
a secondary timing reference. In all cases, the CSM monitors and
determines what reference to use at a given time.
– Each CSM (of a redundant pair at each BTS) is
associated with “partner” MCCs. CSMs must be
enabled before the partner MCC can be enabled.
– The CSM(s) and MCC(s) to be enabled must have
been downloaded with code (Yellow, OOS–RAM)

CSM 1 houses the GPS receiver. The enable sequence can take up to one hour (see below).
* IMPORTANT
The GPS satellite system satellites are not in a geosynchronous orbit and are maintained and
operated by the United States Department of Defense (D.O.D.). The D.O.D. periodically alters
satellite orbits; therefore, satellite trajectories are subject to change. A GPS receiver that is INS
contains an “almanac” that is updated periodically to take these changes into account.
If a GPS receiver has not been updated for a number of weeks, it may take up to an hour for the
GPS receiver “almanac” to be updated.
Once updated, the GPS receiver must track at least four satellites and obtain (hold) a 3–D position
fix for a minimum of 45 seconds before the CSM will come in service. (In some cases, the GPS
receiver needs to track only one satellite, depending on accuracy mode set during the data load).
2NOTE
If equipped with two CSMs, CSM–1 should be bright green (INS–ACT) and CSM–2 should be
dark green(INS–STB)
If more than an hour has passed, refer to CSM Verification, see Figure 3-20 and Table 3-21 to
determine the cause.
NOTE
After the CSMs have been successfully enabled, observe the PWR/ALM LEDs are steady green

CSM System Time – GPS & HSO Verification
July 1999 3-29
SC 4812ET BTS Optimization/ATP – CDMA LMF
PRELIMINARY 2
CSM & LFR Background
The primary function of the Clock Synchronization Manager (CSM)
boards (1 & 2) is to maintain CDMA System Time. The master GLI can
request and distribute system time to the appropriate modules within a
C–CCP shelf. The redundant GLI (slave) obtains system time from the
master GLI over the LAN. All boards are mounted in the C–CCP shelf.
Each CSM board features an ovenized, crystal oscillator that provides
19.6608 MHz clock, even second tick reference, and 3 MHz sinewave
reference, referenced to the selected synchronization source (GPS,
LORAN–C Frequency Receiver (LFR), or High Stability Oscillator
(HSO), T1 Span, or external reference oscillator sources). The 3 MHz
signals are also routed to the RDM EXP 1A & 1B connectors on the top
interconnect panel for distribution to co–located frames at the site.
Fault management has the capability of switching between the CSM 1
and 2 boards in the event of a GPS receiver failure on CSM 1 or a
reference oscillator failure on either CSM board. During normal
operation, the CSM 1 board oscillator output is selected as the source.
The source selection can also be overridden via the LMF or by the GLI
card.

High Stability Oscillator (HSO)
The High Stability Oscillator (HSO) module is a separate full–size card
which resides in a dedicated slot in the lower half of the C–CCP shelf.
This is a completely self contained high stability 10 MHz oscillator
which interfaces with the CSM via a serial communications link. The
CSM handles the overall configuration and status monitoring functions
of the HSO. In the event of GPS failure, the HSO is capable of
maintaining synchronization initially established by the GPS reference
signal for a limited time
The HSO is basically a high stability 10 MHz oscillator with the
necessary interface to the CSMs. The HSO is typically installed in those
geographical areas not covered by the LORAN–C system and provides
the following major functions:
SReference oscillator temperature and phase lock monitor circuitry
SInternal oscillator generates highly stable 10 MHz sine wave, and
routed to reference divider circuitry
SReference divider circuitry converts 10 MHz sine wave to 10 MHz
TTL signal, which is divided to provide a 1 PPS strobe to the CSM
Equipment Warm–up
Allow the base site and test equipment to warm up for 60 minutes
after any interruption in oscillator power. CSM board warm-up allows
the oscillator oven temperature and oscillator frequency to stabilize prior
to test. Test equipment warm-up allows the Rubidium standard timebase
to stabilize in frequency before any measurements are made.
CSM frequency verification
The objective of this procedure is the initial verification of the Clock
Synchronization Module (CSM) boards prior to performing the rf path
verification tests. Parts of this procedure will be repeated for final
verification after the overall optimization has been completed.

* IMPORTANT
If any of the above mentioned areas fail, verify:
– If LED is RED, verify that HSO had been powered up for at least 5 minutes. After oscillator
temperature is stable, LED should go GREEN Wait for this to occur before continuing !
– If “timed out” is displayed in the Last Phase column, suspect the HSO output buffer or oscillator
is defective

Connecting Test Equipment to
the BTS: Overview
All test equipment is controlled by the LMF via IEEE–488/GPIB bus.
The LMF requires each piece of test equipment to have a factory set
GPIB address. If there is a communications problem between the LMF
and any piece of test equipment, verify that the GPIB addresses have
been set correctly (normally 13 for a power meter and 18 for a CDMA
analyzer).
This procedure requires working on our around circuitry
extremely sensitive to ESD. To prevent damage, wear a
conductive, high impedance wrist strap during handling of
any circuit board or module.
Follow appropriate safety measures.
CAUTION
Refer to Table 3-23 for an overview of connections for test equipment
currently supported by LMF.
Typical DIP switch positions and/or configurations are
shown in the following procedure and illustrations. If any
additional information is required, refer to the test
equipment OEM user manuals.

Test Set Calibration
PRELIMINARY 2
July 1999 3-51
SC 4812ET BTS Optimization/ATP – CDMA LMF
Background
Proper test equipment setup ensures that the test equipment and
associated test cables do not introduce measurement errors, and that
measurements are correct.
If the test set being used to interface with the BTS has been
calibrated and maintained as a set, this procedure does not
need to be performed. (Test Set includes LMF terminal,
communications test set, additional test equipment,
associated test cables, and adapters).
NOTE
This procedure must be performed prior to beginning the optimization.
Verify all test equipment (including all associated test cables and
adapters actually used to interface all test equipment and the BTS) has
been calibrated and maintained as a set.
If any piece of test equipment, test cable, or RF adapter,
that makes up the calibrated test equipment set, has been
replaced, re-calibration must be performed. Failure to do so
can introduce measurement errors, resulting in incorrect
measurements and degradation to system performance.
CAUTION
Calibration of the communications test set (or equivalent
test equipment) must be performed at the site before
calibrating the overall test set. Calibrate the test equipment
after it has been allowed to warm–up and stabilize for a
minimum of 60 minutes.
IMPORTANT
*
Purpose
These procedures access the CDMA LMF automated calibration routine
used to determine the path losses of the supported communications
analyzer, power meter, associated test cables, and (if used) antenna
switch that make up the overall calibrated test set. After calibration, the
gain/loss offset values are stored in a test measurement offset file on the
CDMA LMF.

Calibrating Test Equipment
The calibrate test equipment function zeros the power measurement level
of the test equipment item that is to be used for TX calibration and audit.
If both a power meter and an analyzer are connected, only the power
meter is zeroed.
The Calibrate Test Equipment menu item from the Device menu list is
used to calibrate test equipment. The test equipment must be selected
before beginning calibration. Follow the procedure in Table 3-28 to
calibrate the test equipment.

Calibrating Cables
The cable calibration function is used to measure the loss (in dB) for the
TX and RX cables that are to be used for testing. A CDMA analyzer is
used to measure the loss of each cable configuration (TX cable
configuration and RX cable configuration). The cable calibration
consists of the following steps.
SMeasure the loss of a short cable. This is done to compensate for any
measurement error of the analyzer. The sort cable, which is used only
for the calibration process, is used in series with both the TX and RX

cable configuration when they are measured. The measured loss of the
short cable is deducted from the measured loss of the TX and RX
cable configuration to determine the actual loss of the TX and RX
cable configurations. This deduction is done so any error in the
analyzer measurement will be adjusted out of both the TX and RX
measurements.
SThe short cable plus the RX cable configuration loss is measured. The
RX cable configuration normally consists only of a coax cable with
type–N connectors that is long enough to reach from the BTS RX port
the test equipment.
SThe short cable plus the TX cable configuration loss is measured. The
TX cable configuration normally consists of two coax cables with
type–N connectors and a directional coupler, a load, and an additional
attenuator if required by the BTS type. The total loss of the path loss
of the TX cable configuration must be as required for the BTS
(normally 30, 40, or 50 dB). The Motorola Cybertest analyzer is
different in that the required attenuation/load is built into the test set
so the TX cable configuration consists only of the required length
coax cable.
Calibrating Cables with a
CDMA Analyzer
The Cable Calibration menu item from the Util menu list is used to
calibrate both TX and RX test cables for use with CDMA LMF.
Cable calibration cannot be accomplished with an HP8921
analyzer. A different analyzer type or the signal generator
and spectrum analyzer method must be used (refer to
Table 3-30 and Figure 3-23). Cable calibration values must
be manually entered if the signal generator and spectrum
analyzer method is used.
NOTE
The test equipment must be selected before this procedure can be started.
Follow the procedure in Table 3-29 to calibrate the cables. Figure 3-15
illustrates the cable calibration test equipment setup.
Table 3-29: Cable Calibration
nStep Action
1From the Util menu, select Cable Calibration. A Cable Calibration window is displayed.
2Enter a channel number(s) in the Channels box. Multiple channels numbers must be separated
with a comma, no space (i.e., 200,800). When two or more channels numbers are entered, the
cables will be calibrated for each channel. Interpolation will be accomplished for other channels as
required for TX calibration.

3Use spectrum analyzer to measure signal generator output (see Figure 3-23, “A”) and record the value.
4Connect the spectrum analyzer’s short cable to point “B”, as shown in the lower portion of the
diagram, to measure cable output at customer frequency (1840–1870 MHz for Korea PCS and
1930–1990 MHz for North American PCS) and record the value at point “B”.
5Calibration factor = A – B
Example: Cal = –1 dBm – (–53.5 dBm) = 52.5 dB
NOTE
The short cable is used for calibration only. It is not part of the final test setup. After calibration is
completed, do not re-arrange any cables. Use the equipment setup, as is, to ensure test procedures use
the correct calibration factor.

Bay Level Offset Calibration
July 1999 3-61
SC 4812ET BTS Optimization/ATP – CDMA LMF
PRELIMINARY 2
Introduction
Calibration compensates for normal equipment variations within the
BTS and assures maximum measurement accuracy.
RF Path Bay Level Offset
Calibration
Calibration identifies the accumulated gain in every transmit path
(BBX2 slot) at the BTS site and stores that value in the CAL file. The
BLOs are subsequently downloaded to each BBX2.
Each receive path starts at a BTS RX antenna port and terminates at a
backplane BBX2 slot. Each transmit path starts at a BBX2 backplane
slot, travels through the LPA, and terminates at a BTS TX antenna port.
Calibration identifies the accumulated gain in every transmit path
(BBX2 slot) at the BTS site and stores that value in the CAL file. Each
transmit path starts at a C–CCP shelf backplane BBX2 slot, travels
through the LPA, and ends at a BTS TX antenna port. When the TX path
calibration is performed, the RX path BLO will automatically be set to
the default value of 16 dB. This is shown in the bts–bts#.cal file as a
converted decimal value of 16600.
At omni sites, BBX2 slots 1 and R1 (for 1-carrier) or slots 1, R1, 2, and
R2 (for 2-carrier) are tested. At sector sites, BBX2 slots 1 through R1
(for 1-carrier) or slots 1 through R21(for 2-carrier) are tested. Only those
slots (sectors) actually equipped in the current CDF file are tested,
regardless of physical BBX2 board installation in the slot.
When to Re-calibrate BLOs Calibration of BLOs is required after initial BTS installation.
The BLO data of an operational BTS site must be re-calibrated once
each year. Motorola recommends re-calibrating the BLO data for all
associated RF paths after replacing any of the following components or
associated interconnecting RF cabling:
SBBX2 board
SC–CCP shelf
SCIO card
SCIO to LPA backplane RF cable
SLPA backplane
SLPA
STX filter / TX filter combiner
STX thru-port cable to the top of frame

TX Path Calibration
The TX Path Calibration assures correct site installation, cabling, and the
first order functionality of all installed equipment. The proper function
of each RF path is verified during calibration. The external test
equipment is used to validate/calibrate the TX paths of the BTS.
Before installing any test equipment directly to any TX
OUT connector you must first verify that there are no
CDMA channels keyed. Have the OMC–R place the sector
assigned to the LPA under test OOS. Failure to do so can
result in serious personal injury and/or equipment damage.
WARNING
Always wear a conductive, high impedance wrist strap
while handling any circuit card/module. If this is not done,
there is a high probability that the card/module could be
damaged by ESD.
CAUTION
At new site installations, to facilitate the complete test of
each CCP shelf (if the shelf is not already fully populated
with BBX2 boards), move BBX2 boards from shelves
currently not under test and install them into the empty
BBX2 slots of the shelf currently being tested to insure that
all BBX2 TX paths are tested.
– This procedure can be bypassed on operational sites
that are due for periodic optimization.
– Prior to testing, view the CDF file to verify the
correct BBX2 slots are equipped. Edit the file as
required to include BBX2 slots not currently
equipped (per Systems Engineering documentation).

PRELIMINARY 2
BLO Calibration Data File
During the calibration process, the LMF creates a calibration (BLO) data
file. After calibration has been completed, this offset data must be
downloaded to the BBX2s using the Download BLO function. An
explanation of the file is shown below.
Due to the size of the file, Motorola recommends that you
print out a hard copy of a bts.cal file and refer to it for the
following descriptions.
NOTE
The CAL file is subdivided into sections organized on a per slot basis (a
slot Block).
Slot 1 contains the calibration data for the 12 BBX2 slots. Slot 20
contains the calibration data for the redundant BBX2. Each BBX2 slot
header block contains:
SA creation Date and Time – broken down into separate parameters of
createMonth, createDay, createYear, createHour, and createMin.
SThe number of calibration entries – fixed at 720 entries corresponding
to 360 calibration points of the CAL file including the slot header and
actual calibration data.
SThe calibration data for a BBX2 is organized as a large flat array. The
array is organized by branch, sector, and calibration point.
– The first breakdown of the array indicates which branch the
contained calibration points are for. The array covers transmit, main
receive and diversity receive offsets as follows:
Table 3-33: BLO BTS.cal file Array Assignments

– The second breakdown of the array is per sector. Three sectors are
allowed.
Table 3-34: BTS.cal file Array (per sector)
Sector TX RX RX Diversity
1 (Omni) C[1]–C[20] C[241]–C[260] C[481]–C[500]

6 C[101]–[120] C[341]–C[360] C[581]–C[600]
SRefer to the hard copy of the file. As you can see, 10 calibration
points per sector are supported for each branch. Two entries are
required for each calibration point.
SThe first value (all odd entries) refer to the CDMA channel
(frequency) the BLO is measured at. The second value (all even
entries) is the power set level. The valid range for PwrLvlAdj is from
2500 to 27500 (2500 corresponds to –125 dBm and 27500
corresponds to +125 dBm).
SThe 20 calibration entries for each sector/branch combination must be
stored in order of increasing frequency. If less than 10 points
(frequencies) are calibrated, the largest frequency that is calibrated is
repeated to fill out the 10 points.
Example:
C[1]=384, odd cal entry = 1 ‘‘calibration point”
C[2]=19102, even cal entry
C[3]=777,
C[4]=19086,
.
.
C[19]=777,
C[20]=19086, (since only two cal points were calibrated this
would be repeated for the next 8 points)
SWhen the BBX2 is loaded with BLO data, the cal file data for the
BBX2 is downloaded to the device in the order it is stored in the CAL
file. TxCal data is sent first, C[1] – C[60]. Sector 1’s 10 calibration
points are sent (C[1] – C[20]), followed by sector 2’s 10 calibration
points (C[21] – C[40]), etc. The RxCal data is sent next, followed by
the RxDCal data.
STemperature compensation data is also stored in the cal file for each
slot.

Transmit (TX) Path Calibration
The assigned channel frequency and power level (as measured at the top
of the frame) for transmit calibration is derived from the site CDF file.
For each BBX2, the channel frequency is specified in the ChannelList
CDF file parameter and the power is specified in the SIFPilotPwr
CDF file parameter for the sector associated with the BBX2 (located
under the ParentSECTOR field of the ParentCARRIER CDF file
parameter).
The calibration procedure attempts to adjust power to within +0.5 dB of
the desired power.
Perform the calibration of the transmit paths of all equipped BBX2 slots
per the steps in Table 3-36. TX BLO is approximately 40 dB +3.0 dB.
TX BLO = Frame Power Output minus BBX2 output level.

RFDS Calibration
The RFDS Calibration option is used to calibrate the RFDS TX and RX
paths. For a TX antenna path calibration the BTS XCVR is keyed at a
pre–determined power level and the BTS power output level is measured
by the RFDS. The power level is then measured at the TX antenna
directional coupler by the power measuring test equipment item being
used (power meter or analyzer). The difference (offset) between the
power level at the RFDS and the power level at the TX antenna
directional coupler is used as the TX RFDS calibration offset value.
For an RX antenna path calibration the RFDS is keyed at a
pre–determined power level and the power input level is measured by the
BTS XCVR. A CDMA signal at the same power level measured by the
BTS XCVR is then injected at the RX antenna directional coupler by the
CDMA communications analyzer. The difference (offset) between the
RFDS keyed power level and power level measured at the BTS XCVR is
the RFDS RX calibration offset value.
The TX and RX RFDS calibration offset values are written to the CAL
file.

Transmit & Receive Antenna VSWR
July 1999 3-79
SC 4812ET BTS Optimization/ATP – CDMA LMF
PRELIMINARY 2
Purpose
The following procedures will verify that the Voltage Standing Wave
Ratio (VSWR) of all antennas and associated feed lines fall within
acceptable limits. The tests will be performed on all antennas in a
sequential manner (i.e., ANT 1, then ANT 2) until all antennas/feedlines
have been verified.
These procedures should be performed periodically by measuring each
respective antenna’s VSWR (reflected power) to verify that the antenna
system is within acceptable limits. This will ensure continued peak
system performance.
The antenna VSWR will be calculated at the CDMA carrier frequency
assigned to each antenna. Record and verify that they meet the test
specification of less than or equal to 1.5:1.
It is recommended that the installer be familiar with the
following procedure in its entirety before beginning the
actual procedure. Ensure that the entire site is currently not
in service.
IMPORTANT
*
This test is used to test RX antennas by substituting RX
frequencies for TX frequencies.
NOTE
Study the site engineering documents and perform the following tests
only after first verifying that the RF cabling configuration required to
interconnect the BTS frames and antennas meet requirements called out
in the BTS Installation Manual.
Test equipment
The following pieces of test equipment will be required to perform this
test:
SDirectional coupler
SCommunications test set
Prior to performing antenna tests, insure that no CDMA
BBX channels are keyed. Failure to do so could result in
personal injury or serious equipment damage.

Automated Acceptance Test Procedures – All-inclusive TX & RX
July 1999 4-1
SC 4812ET BTS Optimization/ATP – CDMA LMF
PRELIMINARY 2
Introduction
The Automated Acceptance Test Procedure (ATP) allows Motorola
Cellular Field Engineers (CFEs) to run automated acceptance tests on all
equipped BTS subsystem devices using the Local Maintenance Facility
(LMF) and supported test equipment per the current Cell Site Data File
(CDF) assignment.
The results of these tests (at the option of the operator) are written to a
file that can be printed. All tests are controlled via the LMF platform
using the GPIB interface, therefore, only recommended test equipment
supported by the LMF can be used.
The ATP test is to be performed on out-of-service sectors
only.
DO NOT substitute test equipment with other modes not
supported by the LMF.
IMPORTANT
*
Refer to Chapter 3 for detailed information on test set
connections for calibrating equipment, cables and other test
set components, if required.
NOTE
Customer requirements determine which ATP tests to are to be
performed and the field engineer selects the appropriate ATP tests to run.
The tests can be run individually or as one of the following groups:
SAll TX: TX tests verify the performance of the BTS transmit line up.
These include the GLI2, MCC, BBX2, and BIO cards, the LPAs and
passive components including splitters, combiners, bandpass filter,
and RF cables.
SAll RX: RX tests verify the performance of the BTS receiver line up.
These includes the MPC (for starter frames), EMPC (for expansion
frames), BIO, BBX2, MCC, and GLI2 cards and the passive
components including RX filter (starter frame only), and RF cables.
SAll TX/RX: Executes all the TX and RX tests.
SFull Optimization: Executes the TX calibration, download BLO and
TX audit before running all of the TX and RX tests.

Individual Acceptance Tests The followingindividual ATP tests can be used to verify the results of
specific tests:
Spectral Purity TX Mask
This test verifies that the transmitted CDMA carrier waveform,
generated on each sector, meets the transmit spectral mask specification
with respect to the assigned CDF file values.
Waveform Quality (rho)
This test verifies that the transmitted Pilot channel element digital
waveform quality (rho) exceeds the minimum specified value in
ANSI–J_STD–019. “Rho” represents the correlation between actual and
perfect CDMA modulation spectrum. A rho value of 1.0000 represents
100% (or perfect correlation).
Pilot Time Offset
The Pilot Time Offset is the difference between the CDMA analyzer
measurement interval (based on the BTS system time reference) and the
incoming block of transmitted data from the BTS (Pilot only, Pilot
Gain = 262, PN Offset = 0).
Code Domain Power
This test verifies the code domain power levels, which have been set for
all ODD numbered Walsh channels, using the OCNS command. This is
done by verifying that the ratio of PILOT divided by OCNS is equal to
10.2 + 2 dB, and, that the noise floor of all EVEN numbered “OFF”

SC 4812ET BTS Optimization/ATP – CDMA LMF
PRELIMINARY 2
Background: Tx Mask Test
This test verifies the spectral purity of each BBX2 carrier keyed up at a
specific frequency, per the current CDF file assignment. All tests are
performed using the external calibrated test set, controlled by the same
command. All measurements are through the appropriate TX OUT
(BTS/RFDS) connector.
The Pilot Gain is set to 541 for each antenna and all channel elements
from the MCCs are forward-link disabled. The BBX2 is keyed up, using
both bbxlvl and bay level offsets, to generate a CDMA carrier (with pilot
channel element only). BBX2 power output is set to obtain +40 dBm as
measured at the TX OUT connector (on either the BTS or RFDS
directional coupler).
TX output power is set to +40 dBm by setting BTS power
level to +33.5 dBm to compensate for 6.5 dB increase from
pilot gain set to 541.
NOTE
The calibrated communications test set measures and returns the
attenuation level of all spurious and IM products in a 30 kHz resolution
bandwidth with respect to the mean power of the CDMA channel,
measured in a 1.23 MHz bandwidth, in dB, verifying that results meet
system tolerances at the following test points:
Sat least –45 dB @ + 900 kHz from center frequency,
Sat least –45 dB @ – 900 kHz from center frequency.
The BBX2 then de-keys and the applicable redundant BBX2 is assigned
to the current TX antenna path under test. The test is then repeated.
The LMF Tests menu list item, TX Mask, performs the Spectral Purity
TX Mask test for a XCVR(s). All measurements are made through the

4-18
Background: Code Domain
Power Test
This test verifies the Code Domain Power/Noise of each BBX2 carrier
keyed up at a specific frequency per the current CDF file assignment.
All tests are performed using the external calibrated test set controlled by
the same command. All measurements are via the appropriate TX OUT
(BTS/RFDS) connector.
For each sector/antenna under test, the Pilot Gain is set to 262 and all
MCC channel elements under test are configured to generate Orthogonal
Channel Noise Source (OCNS) on different odd Walsh codes, and are
assigned a full–rate gain of 81. The maximum number of MCC/CEs to
be tested an any one time is 32 (32 odd Walsh codes). If more than 32
CEs exist, then multiple sets of measurements are made, so all channel
elements are verified on all sectors.
BBX2 power output is set to 40 dBm as measured at the TX OUT
connector (on either the BTS or RFDS directional coupler).
Code domain power levels, which have been set for all ODD numbered
Walsh channels, are verified using the OCNS command. This is done by
verifying that Pilot Power (dBm) minus OCNS Power (dBm) is equal to
10.2 + 2 dB and that the noise floor of all “OFF” Walsh channels
measures < –27 dB (with respect to total CDMA channel power).

Problem Description
Many of the Clock Synchronization Manager (CSM) boards may be
resolved in the field before sending the boards to the factory for repair.
This section describes known CSM problems identified in field returns,
some of which are field-repairable. Check these problems before
returning suspect CSM boards.
Intermittent 19.6608 MHz
Reference Clock / GPS
Receiver Operation If having any problems with CSM board kit numbers, SGLN1145 or
SGLN4132, check the suffix with the kit number. If the kit has version
“AB,” then replace with version ‘‘BC’’ or higher, and return model AB
to the repair center.
No GPS Reference Source
Check the CSM boards for proper hardware configuration. CSM kit
SGLN1145, in Slot l, has an on-board GPS receiver; while kit
SGLN4132, in Slot 2, does not have a GPS receiver. Any incorrectly
configured board must be returned to the repair center. Do not attempt to
change hardware configuration in the field. Also, verify the GPS
antenna is not damaged and is installed per recommended guidelines.
Checksum Failure The CSM could have corrupted data in its firmware resulting in a
non-executable code. The problem is usually caused by either electrical
disturbance, or interruption of data during a download. Attempt another
download with no interruptions in the data transfer. Return CSM board
back to repair center if the attempt to reload fails.
GPS Bad RX Message Type
This is believed to be caused by a later version of CSM software (3.5 or
higher) being downloaded, via LMF, followed by an earlier version of
CSM software (3.4 or lower), being downloaded from the CBSC.
Download again with CSM software code 3.5 or higher. Return CSM
board back to repair center if attempt to reload fails.
CSM Reference Source
Configuration Error This is caused by incorrect reference source configuration performed in
the field by software download. CSM kit SGLN1145 and SGLN4132
must have proper reference sources configured (as shown below) to
function correctly.
CSM Kit No. Hardware Configuration CSM Slot No. Reference Source Configuration
SGLN1145 With GPS Receiver 1Primary = Local GPS
Backup = Either LFR or HSO

C–CCP Backplane Troubleshooting
July 1999 5-13
SC 4812ET BTS Optimization/ATP – CDMA LMF
PRELIMINARY 2
Introduction
The C–CCP backplane is a multi–layer board that interconnects all the
C–CCP modules. The complexity of this board lends itself to possible
improper diagnoses when problems occur.
Connector Functionality
The following connector overview describes the major types of
backplane connectors along with the functionality of each. This will
allow the Cellular Field Engineer (CFE) to:
SDetermine which connector(s) is associated with a specific problem
type.
SAllow the isolation of problems to a specific cable or connector.
Primary “A” and Redundant “B” ISB (Inter Shelf Bus)
connectors
The 40 pin ISB connectors provide an interface bus from the master
GLI2 to all other GLI2s in the modem frame. Its basic function is to
provide clock synchronization from the master GLI2 to all other GLI2s
in the frame.
The ISB is also provides the following functions:
Sspan line grooming when a single span is used for multiple cages.
Sprovide MMI connection to/from the master GLI2 to cell site modem.
Sprovide interface between GLI2s and the AMR (for reporting BTS
alarms).
Span Line Connector
The span line input is an 8 pin RJ–45 connector that provides a primary
and secondary (if used) span line interface to each GLI2 in the C–CCP
shelf. The span line is used for MM/EMX switch control of the Master
GLI2 and also all the BBX2 traffic.
Primary “A” and Redundant “B” Reference Distribution
Module (RDM) Input/Output
These connectors route the 3 MHz reference signals from the CSMs to
the GLI2s and all BBX2s in the backplane. The signals are used to phase
lock loop all clock circuits on the GLI2’s and BBX2 boards to produce
precise clock and signal frequencies.
Power Input (Return A, B, and C connectors)
Provides a 27 volt input for use by the power supply modules.
Power Supply Module Interface
Each power supply module has a series of three different connectors to
provide the needed inputs/outputs to the C–CCP backplane. These

include a VCC/Ground input connector, a Harting style multiple pin
interface, and a +15V/Analog Ground output connector. The Transceiver
Power Module converts 27/48 Volts to a regulated +15, +6.5, +5.0 volts
to be used by the C–CCP shelf cards.
GLI2 Connector
This connector consists of a Harting 4SU digital connector and a
6–conductor coaxial connector for RDM distribution. The connectors
provide inputs/outputs for the GLI2s in the C–CCP backplane.
GLI2 Ethernet “A” and “B” Connections
These BNC connectors are located on the C–CCP backplane and routed
to the GLI2 board. This interface provides all the control and data
communications between the master GLI2 and the other GLI2, between
gateways, and for the LMF on the LAN.
BBX2 Connector
Each BBX2 connector cnsists of a Harting 2SU/1SU digital connector
and two 6–conductor coaxial connectors. These connectors provide DC,
digital, and RF inputs/outputs for the BBX2s in the C–CCP backplane.
CIO Connectors
SRX RF antenna path signal inputs are routed through RX Tri–Filters
(on the I/O plate), and via coaxial cables to the two MPC modules –
the six “A” (main) signals go to one MPC; the six “B” (diversity) to
the other. The MPC outputs the low–noise–amplified signals via the
C–CCP backplane to the CIO where the signals are split and sent to
the appropriate BBX2.
SA digital bus then routes the baseband signal through the BBX2, to
the backplane, then on to the MCC24 slots.
SDigital TX antenna path signals originate at the MCC24s. Each
output is routed from the MCC24 slot via the backplane appropriate
BBX2.
STX RF path signal originates from the BBX2, through the backplane
to the CIO, through the CIO, and via multi-conductor coaxial cabling
to the LPAs in the LPA shelf.
C–CCP Backplane
Troubleshooting Procedure
The following table provides a standard procedure for troubleshooting
problems that appear to be related to a defective C–CCP backplane. The
table is broken down into possible problems and steps which should be
taken in an attempt to find the root cause.
It is important to note that all steps be followed before
replacing ANY C–CCP backplane.

DC Power Problems
Potentially lethal voltage and current levels are routed to
the BTS equipment. This test must be carried out with a
second person present, acting in a safety role. Remove all
rings, jewelry, and wrist watches prior to beginning this
test.
WARNING
No DC Input Voltage to Power Supply Module
Table 5-22: No DC Input Voltage to Power Supply Module
Step Action
1Verify DC power is applied to the BTS frame. Verify there are
no breakers tripped.
* IMPORTANT
If a breaker has tripped, remove all modules from the
applicable shelf supplied by the breaker and attempt to reset it.
– If breaker trips again, there is probably a cable or breaker
problem within the frame.
– If breaker does not trip, there is probably a defective
module or sub–assembly within the shelf.
2Verify that the C–CCP shelf breaker on the BTS frame
breaker panel is functional.
3Use a voltmeter to determine if the input voltage is being
routed to the C–CCP backplane by measuring the DC voltage
level on the PWR_IN cable.
– If the voltage is not present, there is probably a cable or
breaker problem within the frame.
– If the voltage is present at the connector, reconnect and
measure the level at the “VCC” power feed clip on the
distribution backplane. If the voltage is correct at the
power clip, inspect the clip for damage.
4If everything appears to be correct, visually inspect the power
supply module connectors.
5Replace the power supply module with a known good
module.
6If steps 1 through 4 fail to indicate a problem, the C–CCP

PRELIMINARY 2
Module Status Indicators
Each of the non-passive plug-in modules has a bi-color (green & red)
LED status indicator located on the module front panel. The indicator is
labeled PWR/ALM. If both colors are turned on, the indicator is yellow.
Each plug-in module, except for the fan module, has its own alarm
(fault) detection circuitry that controls the state of the PWR/ALM LED.
The fan TACH signal of each fan module is monitored by the AMR.
Based on the status of this signal the AMR controls the state of the
PWR/ALM LED on the fan module.
LED Status Combinations for
All Modules (except GLI2,
CSM, BBX2, MCC24, MCC8E)
PWR/ALM LED
The following list describes the states of the module status indicator.

FREQ Monitor Connector
A test port provided at the CSM front panel via a BNC receptacle allows
monitoring of the 19.6608 MHz clock generated by the CSM. When
both CSM 1 and CSM 2 are in an in-service (INS) condition, the CSM 2
clock signal frequency is the same as that output by CSM 1.
The clock is a sine wave signal with a minimum amplitude of +2 dBm
(800 mVpp) into a 50 Ω load connected to this port.
SYNC Monitor Connector
A test port provided at the CSM front panel via a BNC receptacle allows
monitoring of the “Even Second Tick” reference signal generated by the
CSMs.
At this port, the reference signal is a TTL active high signal with a pulse
width of 153 nanoseconds.

Periodic maintenance of a site may also may mandate re–optimization of
specific portions of the site. An outline of some basic guidelines is
included in the following tables.
Re–optimization steps listed for any assembly detailed in
the tables below must be performed anytime a RF cable
associated with it is replaced.

Inter-frame Cabling
Optimization must be performed after the replacement of any RF cabling
between BTS frames.

paths.
BTS frame to ancillary frame
(TX) cables The affected sector/antenna TX paths.
Detailed Optimization/ATP
Test Matrix
Table B-3 outlines in more detail the tests that would need to be
performed if one of the BTS components were to fail and be replaced. It
is also assumed that all modules are placed OOS–ROM via the LMF
until full redundancy of all applicable modules is implemented.
The following guidelines should also be noted when using this table.
Not every procedure required to bring the site back on line
is indicated in Table B-3. It is meant to be used as a
guideline ONLY. The table assumes that the user is familiar
enough with the BTS Optimization/ATP procedure to
understand which test equipment set ups, calibrations, and
BTS site preparation will be required before performing the
Table # procedures referenced.
IMPORTANT
*
Various passive BTS components (such as the TX and RX directional
couplers, Preselector IO, CIO; etc.) only call for a TX or RX calibration
audit to be performed in lieu of a full path calibration. If the RX or TX
path calibration audit fails, the entire RF path calibration will need to be
repeated. If the RF path calibration fails, further troubleshooting is
warranted.
Whenever any C–CCP BACKPLANE is replaced, it is assumed that
only power to the C–CCP shelf being replaced is turned off via the
breaker supplying that shelf.
Whenever any DISTRIBUTION BACKPLANE is replaced it is assumed
that the power to the entire RFM frame is removed and the Preselector
I/O is replaced. The modem frame should be brought up as if it were a
new installation.

PRELIMINARY 2
If any significant change in signal level results from any
component being replaced in the RX or TX signal flow
paths, it would be identified by re–running the RX and TX
calibration audit command.
NOTE
When the CIO is replaced, the C–CCP shelf remains powered up. The
BBX2 boards may need to be removed, then re–installed into their
original slots, and re–downloaded (code and BLO data). RX and TX
calibration audits should then be performed.

Appendix C: BBX2 Gain Set Point vs. BTS Output Considerations
July 1999 C-1
SC 4812ET BTS Optimization/ATP – CDMA LMF
PRELIMINARY 2
Usage & Background
Table C-1 outlines the relationship between the total of all code domain
channel element gain settings (digital root sum of the squares) and the
BBX2 Gain Set Point between 33.0 dBm and 44.0 dBm. The resultant
RF output (as measured at the top of the BTS in dBm) is shown in the
table. The table assumes that the BBX2 Bay Level Offset (BLO) values
have been calculated.
As an illustration, consider a BBX2 keyed up to produce a CDMA
carrier with only the Pilot channel (no MCCs forward link enabled).
Pilot gain is set to 262. In this case, the BBX2 Gain Set Point is shown
to correlate exactly to the actual RF output anywhere in the 33 to 44
dBm output range. (This is the level used to calibrate the BTS).

Introduction
Programming of each of the BTS BBX2 synthesizers is performed by the
BTS GLIs via the CHI bus. This programming data determines the
transmit and receive transceiver operating frequencies (channels) for
each BBX2.
PCS Channels
Figure D-1 shows the valid channels for the North American PCS
frequency spectrum. There are 10 CDMA wireline or non–wireline band
channels used in a CDMA system (unique per customer operating
system).

Calculating Center
Frequencies
Table D-1 shows selected CDMA candidate operating channels, listed in
both decimal and hexadecimal, and the corresponding transmit, and
receive frequencies. Center frequency for channels not shown in the table
may be calculated as follows:
Direction Formula Example
TX 1930 + (0.05 * Channel#) Channel 262: 1930 + (0.05*262) = 1943.10
RX 1850 + (0.05 * Channel#) Channel 237: 1850 + (0.05*237) = 1861.85
– Actual frequencies used depend on customer CDMA system
frequency plan.
– Each CDMA channel requires a 1.77 MHz frequency segment. The
actual CDMA carrier is 1.23 MHz wide, with a 0.27 MHz guard
band on both sides of the carrier
– Minimum frequency separation required between any CDMA
carrier and the nearest NAMPS/AMPS carrier is 900 kHz
(center-to-center).

PRELIMINARY 2
PN Offset Background
All channel elements transmitted from a BTS in a particular 1.25 MHz
CDMA channel are orthonogonally spread by 1 of 64 possible Walsh
code functions; additionally, they are also spread by a quadrature pair of
PN sequences unique to each sector.
Overall, the mobile uses this to differentiate multiple signals transmitted
from the same BTS (and surrounding BTS) sectors, and to synchronize
to the next strongest sector.
The PN offset per sector is stored on the BBX2s, where the
corresponding I & Q registers reside.
The PN offset values are determined on a per BTS/per sector(antenna)
basis as determined by the appropriate cdf file content. A breakdown of
this information is found in Table E-1.
PN Offset Usage
There are three basic RF chip delays currently in use. It is important to
determine what RF chip delay is valid to be able to test the BTS
functionality. This can be done by ascertaining if the CDF file
FineTxAdj value was set to “on” when the MCC was downloaded with
“image data”. The FineTxAdj value is used to compensate for the
processing delay (approximately 20 mS) in the BTS using any type of
mobile meeting IS–97 specifications.
If the FineTxAdj value in the cdf file is 213 (D5 HEX), FineTxAdj has
been set for the 14 chip table.
CDF file I and Q values can be represented in DECIMAL
or HEX. If using HEX, add 0x before the HEX value. If
necessary, convert HEX values in Table E-1 to decimal
before comparing them to cdf file I & Q value assignments.
IMPORTANT
*
– If you are using a Qualcomm mobile, use the I and Q values from
the 13 chip delay table.
– If you are using a mobile that does not have the 1 chip offset
problem, (any mobile meeting the IS–97 specification), use the 14
chip delay table.
If the wrong I and Q values are used with the wrong
FineTxAdj parameter, system timing problems will occur.
This will cause the energy transmitted to be “smeared”
over several Walsh codes (instead of the single Walsh code
that it was assigned to), causing erratic operation. Evidence
of smearing is usually identified by Walsh channels not at
correct levels or present when not selected in the Code
Domain Power Test.

PN Offset Background
All channel elements transmitted from a BTS in a particular 1.25 MHz
CDMA channel are orthonogonally spread by 1 of 64 possible Walsh
code functions; additionally, they are also spread by a quadrature pair of
PN sequences unique to each sector.
Overall, the mobile uses this to differentiate multiple signals transmitted
from the same BTS (and surrounding BTS) sectors, and to synchronize
to the next strongest sector.
The PN offset per sector is stored on the BBX2s, where the
corresponding I & Q registers reside.
The PN offset values are determined on a per BTS/per sector(antenna)
basis as determined by the appropriate cdf file content. A breakdown of
this information is found in Table E-2.
PN Offset Usage
There are three basic RF chip delays currently in use. It is important to
determine what RF chip delay is valid to be able to test the BTS
functionality. This can be done by ascertaining if the CDF file
FineTxAdj value was set to “on” when the MCC was downloaded with
“image data”. The FineTxAdj value is used to compensate for the
processing delay (approximately 20 mS) in the BTS using any type of
mobile meeting IS–97 specifications.
Observe the following guidelines:
SIf the FineTxAdj value in the cdf file is 101 (65 HEX), the
FineTxAdj has not been set. The I and Q values from the 0 table
MUST be used.
If the FineTxAdj value in the cdf file is 213 (D5 HEX), FineTxAdj has
been set for the 14 chip table.
SIf the FineTxAdj value in the cdf file is 197 (C5 HEX), FineTxAdj
has been set for the 13 chip table.
CDF file I and Q values can be represented in DECIMAL
or HEX. If using HEX, add 0x before the HEX value. If
necessary, convert HEX values in Table E-2 to decimal
before comparing them to cdf file I & Q value assignments.
IMPORTANT
*
– If you are using a Qualcomm mobile, use the I and Q values from
the 13 chip delay table.
– If you are using a mobile that does not have the 1 chip offset
problem, (any mobile meeting the IS–97 specification), use the 14
chip delay table.

E-2
If the wrong I and Q values are used with the wrong
FineTxAdj parameter, system timing problems will occur.
This will cause the energy transmitted to be “smeared”
over several Walsh codes (instead of the single Walsh code
that it was assigned to), causing erratic operation. Evidence
of smearing is usually identified by Walsh channels not at
correct levels or present when not selected in the Code
Domain Power Test.
