Command Line Interface Overview
The LMF also provides Command Line Interface (CLI) capability.
Activate the CLI by clicking on a shortcut icon on the desktop. The CLI
can not be launched from the GUI, only from the desktop icon.
Both the GUI and the CLI use a program known as the handler. Only one
handler can be running at one time. Due to architectural limitations, the
GUI must be started before the CLI if you want the GUI and CLI to use
the same handler. When the CLI is launched after the GUI, the CLI
automatically finds and uses an in–progress login session with a BTS
initiated under the GUI. This allows the use of the GUI and the CLI in
the same BTS login session. If a CLI handler is already running when
the GUI is launched (this happens if the CLI window is already running
when the user starts the GUI, or if another copy of the GUI is already
running when the user starts the GUI), a dialog window displays the
following warning message:
The CLI handler is already running.
This may cause conflicts with the LMF.
Are you sure you want to start the application?
Yes
No
This window also contains Yes and No buttons. Selecting Yes starts the
application. Selecting No terminates the application.
CLI Format Conventions
The CLI command syntax is as follows:
verb
device including device identifier parameters
switch
option parameters consisting of:
– keywords
– equals signs (=) between the keywords and the parameter values
– parameter values
Spaces are required between the verb, device, switch, and option
parameters. A hyphen is required between the device and its identifiers.
Following is an example of a CLI command.
measure bbx–– rssi channel=6 sector=5
Refer to LMF CLI Commands for a complete explanation of the CLI
commands and their usage.

Logging into a BTS
Logging into a BTS establishes a communication link between the BTS
and the LMF. An LMF session can be logged into only one BTS at a
time.
Prerequisites
Before attempting to log into a BTS, ensure the following have been
completed:
S The LMF is correctly installed on the LMF computer.
S A bts-nnn folder with the correct CDF/NECF and CBSC files exists.
S The LMF computer was connected to the BTS before starting the
Windows operating system and the LMF software. If necessary, restart
the computer after connecting it to the BTS in accordance with
Table 3-5 and Figure 3-3.
CAUTION
Be sure that the correct bts–#.cdf/necf and cbsc–#.cdf file are
used for the BTS. These should be the CDF/NECF files that are
provided for the BTS by the CBSC. Failure to use the correct
CDF/NECF files can result in invalid optimization. Failure to
use the correct CDF/NECF files to log into a live
(traffic–carrying) site can shut down the site.

Logging Out
Logging out of a BTS is accomplished differently for the GUI and CLI
operating environments.
NOTE
The GUI and CLI environments use the same connection to a
BTS. If a GUI and the CLI session are running for the same BTS
at the same time, logging out of the BTS in either environment
will log out of it for both. When either a login or logout is
performed in the CLI window, there is no GUI indication that the
login or logout has occurred.
Logging Out of a BTS from the GUI Environment
Follow the procedure in Table 3-8 to logout of a BTS when using the

Download the BTS
68P09258A31–A
Download the BTS
Overview
Before a BTS can operate, each equipped device must contain device
initialization (ROM) code. ROM code is loaded in all devices during
manufacture or factory repair, or, for software upgrades, from the CBSC
using the DownLoad Manager (DLM). Device application (RAM) code
and data must be downloaded to each equipped device by the user before
the BTS can be made fully functional for the site where it is installed.
ROM Code
Downloading ROM code to BTS devices from the LMF is NOT routine
maintenance nor a normal part of the optimization process. It is only
done in unusual situations where the resident ROM code in the device
does not match the release level of the site operating software AND the
CBSC cannot communicate with the BTS to perform the download.
If you must download ROM code, the procedures are located in
Appendix G.
Before ROM code can be downloaded from the LMF, the correct ROM
code file for each device to be loaded must exist on the LMF computer.
ROM code must be manually selected for download.
NOTE
The ROM code file is not available for GLI3s. GLI3s are ROM
code loaded at the factory.
ROM code can be downloaded to a device that is in any state. After the
download is started, the device being downloaded will change to
OOS_ROM (blue). The device will remain OOS_ROM (blue) when the
download is completed. A compatible revision–level RAM code must
then be downloaded to the device. Compatible code loads for ROM and
RAM must be used for the device type to ensure proper performance.
The compatible device code release levels for the BSS software release
being used are listed in the Version Matrix section of the SCt CDMA
Release Notes (supplied on the tape or CD–ROM containing the BSS
software).
RAM Code
Before RAM code can be downloaded from the LMF, the correct RAM
code file for each device must exist on the LMF computer. RAM code
can be automatically or manually selected depending on the Device
menu item chosen and where the RAM code file for the device is stored
in the LMF file structure. The RAM code file will be selected
automatically if the file is in the :\\cdma\loads\n.n.n.n\code folder (where n.n.n.n is the
download code version number that matches the “NextLoad” parameter
of the CDF file). The RAM code file in the code folder must have the
correct hardware bin number for the device to be loaded.
RAM code can be downloaded to a device that is in any state. After the
download is started, the device being downloaded changes to OOS-ROM
(blue). When the download is completed successfully, the device will
change to OOS-RAM (yellow).

68P09258A31–A
When code is downloaded to an MGLI or GLI, the LMF automatically
also downloads data and then enables the MGLI. When enabled, the
MGLI will change to INS_ACT (bright green). A redundant GLI will
not be automatically enabled and will remain OOS_RAM (yellow).
When the redundant GLI is manually commanded to enable through the
LMF, it will change state to INS_SBY (olive green).
For non–MGLI devices, data must be downloaded after RAM code is
downloaded. To download data, the device state must be OOS–RAM
(yellow).
The devices to be loaded with RAM code and data are:
S Master Group Line Interface (MGLI2 or MGLI3)
S Redundant GLI (GLI2 or GLI3)
S Clock Synchronization Module (CSM) (Only if new revision code
must be loaded)
S Multi Channel Card (MCC24E, MCC8E or MCC–1X)
S Broadband Transceiver (BBX2 or BBX–1X)
S Test Subscriber Interface Card (TSIC) – if RFDS is installed
NOTE
3-36
The MGLI must be successfully downloaded with code and data,
and put INS before downloading any other device. The
download code process for an MGLI automatically downloads
data and enables the MGLI before downloading other devices.
The other devices can be downloaded in any order.

Verify GLI ROM Code Loads
Devices should not be loaded with a RAM code version which is not
compatible with the ROM code with which they are loaded. Before
downloading RAM code and data to the processor cards, follow the
procedure in Table 3-12 to verify the GLI devices are loaded with the
correct ROM code for the software release used by the BSS.
Prerequisite
Identify the correct GLI ROM code load for the software release being

on–board GPS module (RF–GPS) or a remote GPS receiver (R–GPS).
The CSM2 card is required when using the R–GPS. The GPS receiver
(mounted on CSM–1) is 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 remote GPS, LORAN–C LFR, HSO
10 MHz Rubidium source, or HSOX for expansion frames, 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.
Follow the procedure in Table 3-16 to enable the CSMs.
Table 3-16: Enable CSMs
n Step
Action
Click on the target CSM (CSM–2 first, if equipped with two CSMs).
From the Device pull down, select Enable.
– A status report is displayed confirming change in the device(s) status.
– Click OK to close the status report window.
NOTE
– The board in slot CSM 1 interfaces with the GPS receiver. The enable sequence for this board can
take up to one hour (see below).
– FAIL may be shown in the status report table for a slot CSM 1 enable action. If Waiting For Phase
Lock is shown in the Description field, the CSM changes to the Enabled state after phase lock is
achieved.
* 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).

CSM System Time – GPS & LFR/HSO Verification
CSM System Time – GPS & LFR/HSO Verification
CSM & LFR Background
The primary function of the Clock Synchronization Manager (CSM)
boards (slots 1 and 2) is to maintain CDMA system time. The CSM in
slot 1 is the primary timing source while slot 2 provides redundancy. The
CSM2 card (CSM second generation) is required when using the remote
GPS receiver (R–GPS). R–GPS uses a GPS receiver in the antenna head
that has a digital output to the CSM2 card. CSM2 can have a daughter
card as a local GPS receiver to support an RF–GPS signal.
The CSM2 switches between the primary and redundant units (slots 1
and 2) upon failure or command. CDMA Clock Distribution
Cards (CCDs) buffer and distribute even–second reference and 19.6608
MHz clocks. CCD–1 is married to CSM–1 and CCD–2 is married to
CSM 2. A failure on CSM–1 or CCD–1 cause the system to switch to
redundant CSM–2 and CCD–2.
In a typical operation, the primary CSM locks its Digital Phase Locked
Loop (DPLL) circuits to GPS signals. These signals are generated by
either an on–board GPS module (RF–GPS) or a remote GPS receiver
(R–GPS). The CSM2 card is required when using the R–GPS. DPLL
circuits employed by the CSM provide switching between the primary
and redundant unit upon request. Synchronization between the primary
and redundant CSM cards, as well as the LFR or HSO back–up source,
provides excellent reliability and performance.
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 GPS
synchronization source and the LFR/HSO backup source in the event of
a GPS receiver failure on CSM–1. During normal operation, the CSM–1
board selects GPS as the primary source (see Table 3-20). The source
selection can also be overridden via the LMF or by the system software.
Front Panel LEDs
The status of the LEDs on the CSM boards are as follows:
S Steady Green – Master CSM locked to GPS or LFR (INS).
S Rapidly Flashing Green – Standby CSM locked to GPS or LFR
(STBY).
S Flashing Green/Rapidly Flashing Red – CSM OOS–RAM attempting
to lock on GPS signal.
S Rapidly Flashing Green and Red – Alarm condition exists. Trouble
Notifications (TNs) are currently being reported to the GLI.

CSM System Time – GPS & LFR/HSO Verification
68P09258A31–A
Low Frequency Receiver/High Stability Oscillator (LFR/HSO)
The CSM and the LFR/HSO – The CSM performs the overall
configuration and status monitoring functions for the LFR/HSO. In the
event of GPS failure, the LFR/HSO is capable of maintaining
synchronization initially established by the GPS reference signal.
LFR – The LFR requires an active external antenna to receive
LORAN–C RF signals. Timing pulses are derived from this signal,
which is synchronized to Universal Time Coordinates (UTC) and GPS
time. The LFR can maintain system time indefinitely after initial GPS
lock.
HSO – The HSO is 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. Since the
HSO is a free–standing oscillator, system time can only be maintained
for 24 hours after 24 hours of GPS lock
Upgrades and Expansions: LFR2/HSO2/HSOX
LFR2/HSO2 (second generation cards) both export a timing signal to the
expansion or logical BTS frames. The associated expansion or logical
frames require an HSO–expansion (HSOX) whether the starter frame has
an LFR2 or an HSO2. The HSOX accepts input from the starter frame
and interfaces with the CSM cards in the expansion frame. LFR and
LFR2 use the same source code in source selection (see Table 3-19).
HSO, HSO2, and HSOX use the same source code in source selection
(see Table 3-19).
NOTE
3-44
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.

LFR Initialization/Verification
The LORAN–C LFR is a full size card that resides in the C–CCP Shelf.
The LFR is a completely self-contained unit that interfaces with the
CSM via a serial communications link. The CSM handles the overall
configuration and status monitoring functions of the LFR.
The LFR receives a 100 kHz, 35 kHz BW signal from up to 40 stations
(8 chains) simultaneously and provides the following major functions:
S Automatic antenna pre-amplifier calibration (using a second
differential pair between LFR and LFR antenna)
S A 1 second ±200 ηs strobe to the CSM
If the BTS is equipped with an LFR, follow the procedure in Table 3-21
to initialize the LFR and verify proper operation as a backup source for
the GPS.

Note
LORAN–C LFR information (highlighted above in boldface type) is usually the #1 reference source
(verified from left to right).
NOTE
If any of the above mentioned areas fail, verify:
– The LFR antenna is not obstructed or misaligned.
– The antenna pre–amplifier power and calibration twisted pair connections are intact and < 91.4 m
(300 ft) in length.
– A dependable connection to suitable Earth Ground is in place.
– The search list and PLL station for cellsite location are correctly configured .
NOTE
LFR functionality should be verified using the “source” command (as shown in Step 3). Use the
underlined responses on the LFR row to validate correct LFR operation.
Close the Hyperterminal window.
HSO Initialization/Verification
The HSO module is a full–size card that resides in the C–CCP Shelf.
This completely self contained high stability 10 MHz oscillator
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 typically installed in those geographical areas not covered
by the LORAN–C system and provides the following major functions:
S Reference oscillator temperature and phase lock monitor circuitry
S Generates a highly stable 10 MHz sine wave.
S Reference 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
NOTE
To assure BTS stability and contribute to optimization accuracy
of the BTS, warm-up the BTS test equipment prior to
performing the BTS optimization procedure as follows:
– Agilent E7495A for a minimum of 30 minutes
– All other test sets for a minimum of 60 minutes
Time spent running initial or normal power-up, hardware/
firmware audit, and BTS download counts as warm-up time.
WARNING
Before installing any test equipment directly to any BTS TX
OUT connector, verify there are no CDMA channels keyed.
– At active sites, have the OMC-R/CBSC place the antenna
(sector) assigned to the LPA under test OOS. Failure to do
so can result in serious personal injury and/or equipment
damage.

Test Set Calibration
68P09258A31–A
Test Set Calibration
Background
Proper test equipment calibration ensures that the test equipment and
associated test cables do not introduce measurement errors, and that
measurements are correct.
NOTE
If the test equipment set being used to optimize or test the BTS
has been calibrated and maintained as a set, this procedure does
not need to be performed.
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.
CAUTION
If any piece of test equipment, test cable, or RF adapter that
makes up the calibrated test equipment set has been replaced, the
set must be re-calibrated. Failure to do so can introduce
measurement errors, resulting in incorrect measurements and
degradation to system performance. Motorola recommends
repeating cable calibration before testing at each BTS site.
NOTE
Calibration of the communications system analyzer (or
equivalent test equipment) must be performed at the site before
calibrating the overall test equipment set. Calibrate the test
equipment after it has been allowed to warm–up and stabilize for
a minimum of 60 minutes.
Calibration Procedures Included
Automatic
Procedures included in this section use the LMF automated calibration
routine to determine path losses of the supported communications
analyzer, power meter, associated test cables, adapters, and (if used)
antenna switch that make up the overall calibrated test equipment set.
After calibration, the gain/loss offset values are stored in a test
measurement offset file on the LMF computer.
Manual
Agilent E4406A Transmitter Tester – The E4406A does not support
the power level zeroing calibration performed by the LMF. If this
instrument is to be used for Bay Level Offset calibration and calibration
is attempted with the LMF Calibrate Test Equipment function, the
LMF will return a status window failure message stating that zeroing
power is not supported by the E4406A. Refer to the Equipment
Calibration section of Appendix F for instructions on using the
instrument’s self–alignment (calibration) function prior to performing
Bay Level Offset calibration.
Power Meters – Manual power meter calibration procedures to be
performed prior to automated calibration are included in the Equipment
Calibration section of Appendix F.

Cable Calibration – Manual cable calibration procedures using the HP
8921A and Advantest R3465 communications system analyzers are
provided in the Manual Cable Calibration section of Appendix F, if
needed.
GPIB Addresses
GPIB addresses can range from 1 through 30. The LMF will accept any
address in that range, but the numbers entered in the LMF Options
window GPIB address box must match the addresses of the test
equipment. Motorola recommends using 1 for a CDMA signal generator,
13 for a power meter, and 18 for a communications system analyzer. To
verify and, if necessary, change the GPIB addresses of the test
equipment, refer to the Setting GPIB Addresses section of Appendix F.
IP Addresses
For the Agilent E7495A Communications Test Set, set the IP address
and complete initial setup as described in Appendix F (Specifically, see
Table F-1 on page F-3).
Selecting Test Equipment
Serial Connection and Network Connection tabs are provided in the
LMF Options window to specify the test equipment connection method.
The Serial Connection tab is used when the test equipment items are
connected directly to the LMF computer through a GPIB box (normal
setup). The Network Connection tab is used when the test equipment is
to be connected remotely via a network connection or the Agilent
E7495A Communications Test Set is used. Refer to Appendix F
(Specifically, see Table F-1 on page F-3).
Prerequisites
Ensure the following prerequisites have been met before proceeding:
S Test equipment is correctly connected and turned on.
S GPIB addresses set in the test equipment have been verified as correct
using the applicable procedures in Appendix F. (GPIB not applicable
with Agilent E7495A)
S LMF computer serial port and test equipment are connected to the
GPIB box. (GPIB not applicable with Agilent E7495A)
Selecting Test Equipment

Calibrating Cables Overview
The LMF Cable Calibration function is used to measure the path loss (in
dB) for the TX and RX cables, adapters, directional couplers, and
attenuators that make up the cable configurations used for testing. A
communications system analyzer is used to measure the loss of both the
TX test cable and the RX test cable configurations. LMF cable
calibration consists of the following processes:
Measure the loss of a short cable
This is done to compensate for any measurement error of the
communications system analyzer. The short cable, which is used only for
the calibration process, is connected in series with both the TX and RX
test cable configurations when they are measured.
The measured loss of the TX and RX test cable configurations minus the
measured loss of the short cable equals the actual loss of the
configurations. This is done so that any error in the analyzer
measurement is eliminated from both the TX and RX measurements.
Measure the loss of the short cable plus the RX test
cable configuration
The RX test cable configuration normally consists only of a coax cable
with type–N connectors that is long enough to reach from the BTS RX
connector to the test equipment.
When the BTS antenna connectors carry duplexed TX and RX signals, a
directional coupler is required and an additional attenuator may also be
required (for certain BTS types) for the RX test cable configuration.
These additional items must be included in the path loss measurement.
Measure the loss of the short cable plus the TX test
cable configuration
The TX test cable configuration normally consists of two coax cables
with type–N connectors, a directional coupler, a termination load with
sufficient rating to dissipate the BTS output power, and an additional
attenuator, if required by the BTS type. The total path loss of the TX test
configuration must be as required for the BTS (normally 30 or 50 dB).
The Motorola Cybertest analyzer differs from other communications
system analyzers because the required attenuation/load is built into the
test set. Because of this, the Cybertest TX test configuration consists
only of the required length coax cable.

Calibrate Test Cabling using Communications System Analyzer
Cable Calibration is used to calibrate both TX and RX test cables.
Appendix F covers the procedures for manual cable calibration.
NOTE
LMF cable calibration cannot be accomplished using an HP8921
analyzer for 1.7/1.9 GHz. A different analyzer type or the signal
generator and spectrum analyzer method (Table 3-29 and
Figure 3-25) must be used. Cable calibration values must be
manually entered into the LMF cable loss file if the signal
generator and spectrum analyzer method is used. To use the
HP8921A for manual test cable configuration calibration for 800
MHz BTSs, refer to the Manual Cable Calibration section of
Appendix F.
Prerequisites
S Test equipment is turned on and has warmed up for at least 60
minutes. Agilent E7495A requires only 30 minute warmup.
S Test equipment has been selected in the LMF (Table 3-25 or
Table 3-26).
S Test equipment has been calibrated and correctly connected for the
type of test cable configuration to be calibrated.
Calibrating cables
Refer to Figure 3-12, Figure 3-13, or Figure 3-14 and follow the
procedure in Table 3-28 to calibrate the test cable configurations.

Set signal generator to 0 dBm at the customer frequency of:
869–894 MHz for North American Cellular or 1930–1990 MHz for North American PCS
Use spectrum analyzer to measure signal generator output (see Figure 3-25, A) & record the value.
Connect the spectrum analyzer’s short cable to point B, (as shown in the lower right portion of the
diagram) to measure cable output at customer frequency of:
869–894 MHz for North American Cellular or 1930–1990 MHz for North American PCS
Record the value at point B.
Calibration factor = (value measured with detail “A” setup) – (value measured with detail “B” setup)
Example:
Cal factor = –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 test cable configuration as is to ensure test
procedures use the correct calibration factor.

Setting Cable Loss Values
Cable loss values for TX and RX test cable configurations are normally
set by accomplishing automatic cable calibration using the LMF and the
applicable test equipment. The LMF stores the measured loss values in
the cable loss files. The cable loss values can also be set or changed
manually. Follow the procedure in Table 3-31 to set cable loss values.
CAUTION
If cable calibration was performed without using the LMF, cable

Bay Level Offset Calibration
Introduction
Bay Level Offset (BLO) calibration is the central activity of the
optimization process. BLO calibration compensates for normal
equipment variations within the BTS RF paths and assures the correct
transmit power is available at the BTS antenna connectors to meet site
performance requirements.
RF Path Bay Level Offset Calibration
Calibration identifies the accumulated gain in every transmit path (BBX
slot) at the BTS site and stores that value in a BLO database calibration
table in the LMF. The BLOs are subsequently downloaded to each BBX.
For starter frames, each receive path starts at a BTS RX antenna port and
terminates at a backplane BBX slot. Each transmit path starts at a BBX
backplane slot, travels through the Power Amplifier (PA) and terminates
at a BTS TX antenna port.
For expansion frames each receive path starts at the BTS RX port of the
cell site starter frame, travels through the frame-to-frame expansion
cable, and terminates at a backplane BBX slot of the expansion frame.
The transmit path starts at a BBX backplane slot of the expansion frame,
travels though the PA and terminates at a BTS TX antenna port of the
same expansion frame.
Calibration identifies the accumulated gain in every transmit path (BBX
slot) at the BTS site and stores that value in a BLO database. Each
transmit path starts at a C–CCP shelf backplane BBX slot, travels
through the PA, and ends at a BTS TX antenna port. When the TX path
calibration is performed, the RX path BLO is automatically set to the
default value.
At omni sites, BBX slots 1 and 13 (redundant) are tested. At sector sites,
BBX slots 1 through 12, and 13 (redundant) are tested. Only those slots
(sectors) actually equipped in the current CDF are tested, regardless of
physical BBX board installation in the slot.
When to Calibrate BLOs
Calibration of BLOs is required:
S After initial BTS installation
S Once each year
S After replacing any of the following components or associated
interconnecting RF cabling:
– BBX board
– C–CCP shelf
– CIO card
– CIO to Power Amplifier backplane RF cable
– PA backplane
– PA
– TX filter / TX filter combiner
– TX 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.
WARNING
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.
CAUTION
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.
NOTE
At new site installations, to facilitate the complete test of each
CCP shelf (if the shelf is not already fully populated with BBX
boards), move BBX boards from shelves currently not under test
and install them into the empty BBX slots of the shelf currently
being tested to insure that all BBX 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
BBX slots are equipped. Edit the file as required to include
BBX slots not currently equipped (per Systems
Engineering documentation).
BLO Calibration Data File
During the calibration process, the LMF creates a bts–n.cal calibration
(BLO) offset data file in the bts–n folder. After calibration has been
completed, this offset data must be downloaded to the BBXs using the
Download BLO function. An explanation of the file is shown below.
NOTE
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.
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 BBX slots. Slot 20
contains the calibration data for the redundant BBX. Each BBX slot
header block contains:
S A creation Date and Time – broken down into separate parameters of
createMonth, createDay, createYear, createHour, and createMin.
S The 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.

S Ten calibration points per sector are supported for each branch. Two
3-88
entries are required for each calibration point.
The first value (all odd entries) refer to the CDMA channel
(frequency) where the BLO is measured. 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).
The 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)
When the BBX is loaded with image = data, the cal file data for the
BBX is downloaded to the device in the order it is stored in the cal
file. TxCal data is sent first, C[1] – C[240]. Sector 1’s ten calibration
points are sent (C[1] – C[20]) followed by sector 2’s ten calibration
points (C[21] – C[40]), etc. The RxCal data is sent next (C[241] –
C[480]), followed by the RxDCal data (C[481] – C[720]).
Temperature compensation data is also stored in the cal file for each
set.

Test Equipment Set-up for RF Path Calibration
Follow the procedure in Table 3-35 to set up test equipment.
Table 3-35: Set Up Test Equipment for RF Path Calibration
Step
Action
If it has not already been done, refer to the procedure in Table 3-5 (on page 3-17) to interface the LMF
computer terminal to the frame LAN A connector.
If it has not already been done, refer to Table 3-6 (on page 3-26) to start a GUI LMF session.
If required, calibrate the test equipment per the procedure in Table 3-27 (on page 3-78).
NOTE
Verify the GPIB controller is properly connected and turned on.
! CAUTION
To prevent damage to the test equipment, all transmit (TX) test connections must be via the 30 dB
directional coupler for 800 MHz with an additional 20 dB in–line attenuator for 1.7/1.9 GHz.
For TX path calibration, connect the test equipment as shown in Figure 3-16, Figure 3-17, or
Figure 3-19, depending on the communications analyzer being used.
Transmit (TX) Path Calibration Description
The assigned channel frequency and power level (as measured at the top
of the frame) for transmit calibration are derived from the site CDF files.
For each BBX, 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 BBX (located
under the ParentSECTOR field of the ParentCARRIER CDF file
parameter).
NOTE
If both the BTS–x.cdf and CBSC–x.cdf files are current, all
information will be correct on the LMF. If not, the carrier and
channel will have to be set for each test.
The calibration procedure attempts to adjust the power to within +0.5 dB
of the desired power. The calibration will pass if the error is less than
+1.5 dB.
The TX Bay Level Offset at sites WITHOUT the directional coupler
option, is approximately 42.0 dB ±3.0 dB.
S At sites WITHOUT RFDS option, BLO is approximately
42.0 dB ±4.0 dB. A typical example would be TX output power
measured at BTS (36.0 dBm) minus the BBX TX output level
(approximately –6.0 dBm) would equate to 42 dB BLO.
The TX Bay Level Offset at sites WITH the directional coupler option,
is approximately 41.4 dB ±3.0 dB. TX BLO = Frame Power Output
minus BBX output level.
S Example: TX output power measured at RFDS TX coupler
(39.4 dBm) minus the BBX TX output level (approximately
–2.0 dBm) and RFDS directional coupler/cable (approximately
–0.6 dBm) would equate to 41.4 dB BLO.

TX Calibration and the LMF
The LMF Tests > TX > TX Calibration... and Tests > All Cal/Audit...
selections perform TX BLO calibration testing for installed BBX(s). The
All Cal/Audit... selection initiates a series of actions to perform TX
calibration, and if calibration is successful, download BLO and perform
TX audit. The TX Calibration... selection performs only TX
calibration. When TX Calibration... is used, BLO download and TX
audit must be performed as separate activities. The CDMA Test
Parameters window which opens when TX Calibration... or All
Cal/Audit... is selected contains several user–selectable features which
are described in the following subsections.
Rate Set Drop-down Pick List
The Rate Set Drop–down Box is enabled if at least one MCC card is
selected for the test. The available options for TX tests are 1 = 9600, and
3 = 9600 1X. Option 3 is only available if 1X cards are selected for the
test. The available transfer rate options for RX tests are 1 = 9600 and
2 = 14400. Option 2 is only available if no 1X cards are selected.
Verify BLO
In both the TX Calibration and All Cal/Audit dialog boxes, a Verify
BLO checkbox is provided and checked by default. After the actual TX
calibration is completed during either the TX Calibration or All
Cal/Audit process, the BLO derived from the calibration is compared to
a standard, acceptable BLO tolerance for the BTS. In some installations,
additional items may be installed in the transmit path. The additional
change in gain from these items could cause BLO verification failure
and, therefore, failure of the entire calibration. In these cases, either the
Verify BLO checkbox should be unchecked or the additional path losses
should be added into each applicable sector using the
Util>Edit>TX Coupler Loss... function.
Single-Sided BLO Checkbox
Another option that appears in the pull–down menu is Single–sided
BLO. Normally valid BLO values are some value plus–or–minus some
offset. The ranges that we currently use for calibration are wider than
necessary to accommodate the redundant BBX. The lower half of that
range is where non–redundant BBXs should be. When Single–sided
BLO is selected, the result is only considered a success if it is in the
lower half of the range. If it was normally a success from 37–47 (which
is 42 "5), Single–sided BLO would make it a success only if the result
was from 37–42. To get the more stringent conditions, the operator
checks Single–sided BLO when calibrating non–redundant transceivers.
Single–sided BLO carries the likelihood of more failures. This option
should only be used by experienced CFEs.

Test Pattern Drop-down Pick List
The Tests > TX > TX Calibration... menu window has a Test Pattern
pull–down menu. This menu has the following choices:
S Pilot (default) – performs tests using a pilot signal only. This pattern
should be used when running in–service tests. It only requires a BBX
to do the test.
S Standard – performs the tests using pilot, synch, paging and six
traffic channels. This pattern should be used on all non–in–service
tests. Standard requires a BBX and an MCC. Standard uses gain
values specified by the IS97 standard.
S CDFPilot –performs the tests using the pilot signal, however, the gain
is specified in the CDF file. Advanced users may use CDFPilot to
generate a Pilot pattern using the value specified by the PilotGain
parameter in the CDF file instead of a pre–determined value.
S CDF – performs the tests using pilot, synch, paging and six traffic
channels, however, the gain for the channel elements is specified in
the CDF file. Advanced users may use CDF to generate a standard
pattern. Instead of using the values specified by IS97, the settings for
the following CDF parameters are used:
– PilotGain
– PchGain
– SchGain
– NomGain1Way
Set-up for TX Calibration
The workaround in Table 3-36 allows the user to manually set the BLO
limits to ensure that the redundant BBX BLO test does not fail due to the
preset offset being incorrectly set for the frame under test. A future LMF
release will correct this problem.

RFDS Set–up and Calibration
68P09258A31–A
RFDS Calibration
The RFDS Calibration option is used to calibrate the RFDS TX and RX
paths.
TX Path Calibration – 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.
RX Path Calibration – 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 BBX. A CDMA signal at the same power level
measured by the BTS BBX is then injected at the RX antenna directional
coupler by the communications system analyzer. The difference (offset)
between the RFDS–keyed power level and power level measured at the
BTS BBX is the RFDS RX calibration offset value.
RFDS calibration and the CAL file – The TX and RX RFDS
calibration offset values are written to the CAL file in the slot[385]
Block.
TSIC channel frequency – For each RFDS TSIC, the channel
frequency is determined at the lower third and upper third of the
appropriate band using the frequencies listed in Table 3-47.

BTS Redundancy/Alarm Testing
Objective
This section tests the redundancy options that could be included in the
cell site. These tests verify, under a fault condition, that all modules
equipped with redundancy switch operations to their redundant partner
and resume operation. An example would be to pull the currently active
CSM and verify the standby CSM takes over distribution of the CDMA
reference signal.
Redundancy covers many BTS modules. Confirm the redundant options
included in the BTS, and proceed as required. If the BTS has only basic
power supply redundancy, the tests and procedures detailed in the
following tables should be bypassed.
Table 3-52. Miscellaneous Alarm Tests (BTS Frame)

Key-up the BBX assigned to the PAs associated with the sector under test (gain = 40).
Adjust the communications test set spectrum analyzer, as required, to observe the overall carrier
amplitude and IM Shelf and note for reference. These figures will be required later.
NOTE
See Figure 3-19 for test equipment setup, if required.
Push-in and release the breaker supplying the 1st PA of the pair.
NOTE
After power is removed, IM suppression takes a few seconds to settle out while compensating for the
removal of the 1st PA. The overall gain decreases by approximately 6 dB. The process must be
complete before proceeding.
Verify:
• The other PA module did not go OOS due to the loss of the PA.
• The overall carrier amplitude is reduced by approximately 6 dB and IM suppression on the analyzer
display remains basically unchanged.
• PA fault message is reported via the MGLI and displayed on the alarm monitor.
Re-apply power to the PA module and observe the alarm has cleared on the alarm monitor.
NOTE
All PWR/ALM LEDs should be GREEN at completion of test.

Alarms Testing
Alarm Verification
ALARM connectors provide Customer Defined Alarm Inputs and
Outputs. The customer can connect BTS site alarm input sensors and
output devices to the BTS, thus providing alarm reporting of active
sensors as well controlling output devices.
The SC 4812T is capable of concurrently monitoring 36 input signals
coming into the BTS. These inputs are divided between 2 Alarm
connectors marked ‘ALARM A’ and ‘ALARM B’ located at the top of
the frame (see Figure 3-31). The ALARM A connector is always
functional; ALARM B is functional when an AMR module is equipped
in the AMR 2 slot in the distribution shelf. ALARM A port monitors
input numbers 1 through 18, while ALARM B port monitors input
numbers 19 through 36 (see Figure 3-32). State transitions on these input
lines are reported to the LMF and OMCR as MGLI Input Relay alarms.
ALARM A and ALARM B connectors each provide 18 inputs and 8
outputs. If both A and B are functional, 36 inputs and 16 outputs are
available. They may be configured as redundant. The configuration is set
by the CBSC.
Alarm Reporting Display
The Alarm Monitor window can be displayed to list alarms that occur
after the window is displayed. To access the Alarm Monitor window,
select Util>Alarm Monitor.
The following buttons are included:
S The Options button allows for a severity level (Warning, Minor, and
Major) selection. The default is all levels. To change the level of
alarms reported click on the Options button and highlight the desired
alarm level(s). To select multiple levels press the  key (for
individual selections) or  key (for a range of selections) while
clicking on the desired levels.
S The Pause button pauses/stops the display of alarms. When the Pause
button is clicked the name of the button changes to Continue. When
the Continue button is clicked, the display of alarms continues.
Alarms that occur between the time the Pause button is clicked and
the Continue button is clicked are not displayed.
S The Clear button clears the Alarm Monitor display. New alarms that
occur after the Clear button is clicked are displayed.
S The Dismiss button dismisses/closes the Alarm Monitor display.

Automated Acceptance Test Procedures
Introduction
The Automated Acceptance Test Procedure (ATP) allows 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 from the LMF platform
using the GPIB interface, therefore, only recommended test equipment
supported by the LMF can be used.
This chapter describes the tests run from the GUI environment, which is
the recommended method. The GUI provides the advantages of
simplifying the LMF user interface, reducing the potential for miskeying
commmands and associated parameters, and speeding up the execution
of complex operations involving multiple command strings. If you feel
the command line interface (CLI) will provide additional insight into the
progress of ATPs and problems that could possibly be encountered, refer
to LMF CLI Commands.
NOTE
– Before performing any tests, use an editor to view the
“Caveats” section of the “readme.txt” file in the c:\wlmf
folder for any applicable information.
– The ATP test is to be performed on out-of-service (OOS)
sectors only.
– DO NOT substitute test equipment not supported by the
LMF.
Refer to Chapter 3 for detailed interconnection information needed for
calibrating equipment, cables, and other test equipment set components.

Reduced ATP
NOTE
Equipment has been factory–tested for FCC compliance. If
license–governing bodies require documentation supporting
SITE compliance with regulations, a full ATP may be necessary.
Perform the Reduced ATP only if reports for the specific BTS
site are NOT required.
After downloading the proper operational software to the BTS, the CFE
must perform these procedures (minimal recommendation):
1. Verify the TX/RX paths by performing TX Calibration, TX Audit,
and FER tests.
2. Retrieve Calibration Data required for normal site operation.
Should failures occur while performing the specified tests, refer to the
Basic Troubleshooting section of this manual for help in determining the
failure point. Once the point of failure has been identified and corrected,
refer to the BTS Optimization and ATP Test Matrix (Table C-3) to
determine the applicable test that must be performed.
In the unlikely event that the BTS passes these tests but has a forward
link problem during normal operation, the CFE should then perform the
additional TX tests for troubleshooting: TX spectral mask, TX rho, and
TX code domain.
NOTE
Refer to Chapter 3 for detailed information on test set
connections for calibrating equipment, cables and other test set
components, if required.
Customer requirements determine which ATP tests are to be performed
and the field engineer selects the appropriate ATP tests to run.

ATP Test Options
There are three different ATP testing options that can be performed to
completely test a BTS. Depending on your requirements, one of the
following ATP testing options should be run. Table 4-1 provides the
procedure to execute an ATP test. To completely test a BTS, run the ATP
tests according to one of the following ATP testing options:
ATP Testing Option 1
S All TX/RX test – Executes all the TX and RX tests as described in
testing option 2.
ATP Testing Option 2
S All TX test – TX tests verify the performance of the BTS transmit line
up. These include the GLI, MCC, BBX, and CIO cards, the LPAs and
passive components including splitters, combiners, bandpass filter,
and RF cables.
S All RX test – RX tests verify the performance of the BTS receiver line
up. These includes the MPC (for starter frames), EMPC (for
expansion frames), CIO, BBX, MCC, and GLI cards and the passive
components including RX filter (starter frame only), and RF cables.
ATP Testing Option 3
These tests can be run individually:
4-4
TX Mask test
Rho test
Pilot Time Offset test
Code Domain Power test
FER test
NOTE
The Full Optimization test can be run if you want the TX path
calibrated, BLO downloaded, and TX audited before all the TX
and RX tests are run.
NOTE
If manual testing has been performed with the HP analyzer,
remove the manual control/system memory card from the card
slot and set the IO CONFIG to the Talk & Listen mode before
starting the automated testing.
NOTE
The STOP button can be used to stop the testing process.

ATP Test Prerequisites
Before attempting to run any ATP tests, ensure the following have been
completed:
S BTS has been optimized and calibrated (see Chapter 3).
S LMF is logged into the BTS.
S CSMs, GLIs, BBXs, MCCs, and TSU (if the RFDS is installed) have
correct code load and data load.
Primary CSM, GLI, and MCCs are INS_ACT (bright green).
BBXs are calibrated and BLOs are downloaded.
No BBXs are keyed (transmitting).
BBXs are OOS_RAM (yellow).
Test cables are calibrated.
Test equipment is connected for ATP tests (see Figure 3-19 through
Figure 3-24 starting on page 3-68).
S Test equipment has been warmed up 60 minutes and calibrated.
S GPIB is on.
S BTS transmit connectors are properly terminated for the test(s) to be
performed.
WARNING
Before performing the FER, be sure that all PAs are turned OFF
(circuit breakers pulled) or that all transmitter ports are properly
terminated.
All transmit ports must be properly terminated for all ATP tests.
Failure to observe these warnings may result in bodily injury or
equipment damage.
TX OUT Connection
NOTE
Oct 2003
Many of the acceptance test procedures require taking
measurements at the TX OUT (BTS/RFDS) connector. At sites
without RFDS installed, all measurements will be via the BTS
TX OUT connector. At sites with RFDS installed, all
measurements will be via the RFDS directional coupler TX
OUT connector.

Individual Acceptance Tests
The following individual ATP tests can be used to evaluate specific
aspects of BTS operation against individual performance requirements.
All testing is performed using the LMF GUI environment.
TX Testing
TX tests verify any given transmit antenna path and output power
control. All tests are performed using the external, calibrated test
equipment. All measurements are made at the appropriate BTS TX OUT
connector(s).
TX tests verify TX operation of the entire CDMA forward link using
selected BBXs assigned to respective sector antennas. Each BBX is
keyed up to generate a CDMA carrier (using both bbxlevel and BLO)
at the CDF file–specified carrier output power level.
RX Testing
RX testing verifies receive antenna paths for BBXs selected for the test.
All tests are performed using the external, calibrated test equipment to
inject a CDMA RF carrier with all zero longcode at the specified RX
frequency at the appropriate BTS RX IN connector(s).
RX tests verify RX operation of the entire CDMA reverse link using all
equipped MCCs assigned to all respective sector/antennas.
Individual Tests
The following individual tests can be used to verify the results of
specific tests.
Spectral Purity TX Mask (Primary & Redundant BBX)
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 (Primary & Redundant BBX)
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”
Walsh channels measures < –27 dB (with respect to total CDMA channel
power).

TX Spectral Purity Transmit Mask Acceptance Test (Tx Mask)
This test verifies the spectral purity of each BBX 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.
The Pilot Gain is set to 541 for each antenna, and all channel elements
from the MCCs are forward-link disabled. The BBX is keyed up, using
both bbxlvl and bay level offsets, to generate a CDMA carrier (with pilot
channel element only). BBX power output is set to obtain +40 dBm as
measured at the TX OUT connector (on either the BTS or RFDS
directional coupler).
NOTE
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.
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, verify that results meet
system tolerances at the following test points:
S 1.7/1.9 GHz:
– at least –45 dB @ + 900 kHz from center frequency
– at least –45 dB @ – 900 kHz from center frequency

TX Waveform Quality (rho) Acceptance Test
This test verifies the transmitted Pilot channel element digital waveform
quality of each BBX 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.
The Pilot Gain is set to 262 for each antenna, and all channel elements
from the MCCs are forward link disabled. The BBX is keyed up, using
both bbxlvl and bay level offsets, to generate a CDMA carrier (with pilot
channel element only, Walsh code 0). BBX power output is set to
40 dBm as measured at the TX OUT connector (on either the BTS or

The calibrated communications test set measures and returns the Pilot
channel element digital waveform quality (rho) in dB, verifying that the
result meets system tolerances:
S Waveform quality (rho) should be w0.912 (–0.4dB).
The BBX then de-keys and, if selected, the MCC is re-configured to
assign the applicable redundant BBX to the current TX antenna path
under test. The test is then repeated.

TX Pilot Time Offset Acceptance Test
This test verifies the transmitted Pilot channel element Pilot Time Offset
of each BBX 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.
The Pilot Gain is set to 262 for each antenna, and all TCH elements from
the MCCs are forward link disabled. The BBX is keyed up, using both
bbxlvl and bay level offsets, to generate a CDMA carrier (with pilot
channel element only, Walsh code 0). BBX power output is set to
40 dBm as measured at the TX OUT connector (on either the BTS or
RFDS directional coupler).
The calibrated communications test set measures and returns the Pilot
Time Offset in µs, verifying results meet system tolerances:
S Pilot Time Offset should be within v3 ms of the target PT
Offset (0 ms).
The BBX then de-keys, and if selected, the MCC is re-configured to
assign the applicable redundant BBX to the current TX antenna path
under test. The test is then repeated.
See Table 4-1 to perform this test.
TX Code Domain Power/Noise Floor Acceptance Test
This test verifies the Code Domain Power/Noise of each BBX 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. All MCC
channel elements under test are configured to generate Orthogonal
Channel Noise Source (OCNS) on different odd Walsh codes and to be
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.
BBX power output is set to 40 dBm as measured at the TX OUT
connector (on either the BTS or RFDS directional coupler).
Verify 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 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 v –27 dB (with respect to total CDMA channel power).
NOTE
Oct 2003
When performing this test using the LMF and the MCC is an MCC8E
or MCC24E, the redundant BBX may fail or show marginal
performance. This is due to a timing mismatch that the LMF does not
address. Performing this test from the CBSC will not have this timing
problem.

Updating Calibration Data Files
Software Release caveats
With Software Release 2.16.1.x, the packet BTS will NOT detect a new
calibration file on the OMC–R. A manual workaround is available in
bulletin cdma_g_bts_059. This will be corrected in Software Release
2.16.3.
Software Release 2.16.3 will allow the user to load the calibration file
from the LMF directly onto the MGLI. The MGLI will then ftp the new
calibration file to the OMC–R, thereby eliminating the need for the user
to place the calibration file at the OMC–R.
Copy and Load Cal File to to CBSC
After completing the TX calibration and audit, updated CAL file
information must be moved from the LMF Windows environment back
to the CBSC, a Unix environment. The following procedures detail
moving files from one environment to the other.
Copying CAL files from LMF to a Diskette
Follow the procedures in Table 5-1 to copy the CAL files from an LMF
computer to a 3.5 diskette.
Table 5-1: Copying CAL Files to a Diskette
Step
Action
With Windows running on the LMF computer, insert a disk into Drive A:\.
Launch the Windows Explorer application program from the Start > Programs menu list.
Select the applicable :\).
With Solaris versions of Unix, create a Unix–formatted version of the bts–#.cal file in the home
directory by performing the following:
9a
– Type in dos2unix /floppy/no_name/bts–#.cal bts–#.cal and press the Enter key.
Where: # = BTS number for which the CAL file was created
NOTE
Other versions of Unix do not support the dos2unix command. In these cases, use the Unix cp (copy)
command. The copied files will contain DOS line feed characters which must be edited out with a
Unix text editor.
10
Type in ls –l *.cal and press the Enter key. Verify the CAL files have been copied. Verify all CAL
files to be transferred appear in the displayed listing.
11
Type eject and press the Enter key.

From the BTS site, contact the OMC–R and request the operator to PREACTIVATE the BTS to the
required software version for the BSS. There are two types of PREACTIVATE load processes:
– Rolling Upgrade: This load process is only available when the BTS cards are populated for full
redundancy as applicable.
– Quick Reboot: This process is used when there is not full redundancy for the BTS cards. The
GLI3 will disable and reboot to the new load. This will cause all the other cards to go out of
service. Once it is rebooted, the GLI3 determines which cards require a new load and then
downloads the cards in the order which they establish communication with the GLI3 following
their reboot. The GLI3 can reload up to 16 devices simultaneously.
After all activities at the site have been completed, contact the OMC–R and confirm that the BTS is

Problem Description
Many of the Clock Synchronization Manager (CSM) board failures 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 the CSM
board back to the repair center if the attempt to reload fails.
GPS Bad RX Message Type
This problem 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 the CSM board back to the repair center if the attempt to reload
fails.
CSM Reference Source Configuration Error
This problem is caused by incorrect reference source configuration
performed in the field by software download. CSM kits SGLN1145 and
SGLN4132 must have proper reference sources configured (as shown
below) to function correctly.

C–CCP Backplane Troubleshooting
68P09258A31–A
C–CCP Backplane Troubleshooting
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
information allows the CFE to:
S Determine which connector(s) is associated with a specific problem
type.
S Isolate problems to a specific cable or connector.
Primary “A” and Redundant “B” Inter Shelf Bus
Connectors
The 40 pin Inter Shelf Bus (ISB) connectors provide an interface bus
from the master GLI to all other GLIs in the modem frame. Their basic
function is to provide clock synchronization from the master GLI to all
other GLIs in the frame.
The ISB also provides the following functions:
S Span line grooming when a single span is used for multiple cages.
S MMI connection to/from the master GLI to cell site modem.
S Interface between GLIs and the AMR (for reporting BTS alarms).
Span Line Connector
The 50–pin span line connector provides a primary and secondary (if
used) span line interface to each GLI in the C–CCP shelf. The span line
is used for MM/EMX switch control of the Master GLI and also all the
BBX traffic.
Primary “A” and Redundant “B” Reference Distribution
Module Input/Output
The Reference Distribution Module (RDM) connectors route the 3 MHz
reference signals from the CSMs to the GLIs and all BBXs in the
backplane. The signals are used to phase lock loop all clock circuits on
the GLIs and BBX boards to produce precise clock and signal
frequencies.
Power Input (Return A, B, and C connectors)
Provides a +27 volt or –48 volt input for use by the power supply
modules.

C–CCP Backplane Troubleshooting
68P09258A31–A
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 +15 V/Analog Ground output connector. The C–CCP
Power Modules convert +27 or –48 Volts to a regulated +15, +6.5, and
+5.0 Volts to be used by the C–CCP shelf cards. In the –48 V BTS, the
LPA power modules convert –48 Volts to a regulated +27 Volts.
GLI 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 GLIs in the C–CCP backplane.
GLI 10Base–2 Ethernet “A” and “B” Connections
These BNC connectors are located on the C–CCP backplane and routed
to the GLI board. This interface provides all the control and data
communications between the master GLI and the other GLI, between
gateways, and for the LMF on the LAN.
BBX Connector
Each BBX connector consists of a Harting 2SU/1SU digital connector
and two 6–conductor coaxial connectors. These connectors provide DC,
digital, and RF inputs/outputs for the BBXs in the C–CCP backplane.
CIO Connectors
S RX 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 BBX.
S A digital bus then routes the baseband signal through the BBX, to the
backplane, then on to the MCC slots.
S Digital TX antenna path signals originate at the MCCs. Each output
is routed from the MCC slot via the backplane appropriate BBX.
S TX RF path signal originates from the BBX, 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
Table 6-15 through Table 6-24 provide procedures for troubleshooting
problems that appear to be related to a defective C–CCP backplane. The
tables are broken down into possible problems and steps that should be
taken in an attempt to find the root cause.

DC Power Problems
Perform the procedure in Table 6-22 to troubleshoot a DC input voltage
to power supply module failure.
WARNING
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.
No DC Input Voltage to Power Supply Module
Table 6-22: No DC Input Voltage to Power Supply Module
Step
Action
Verify 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 the breaker trips again, there is probably a cable or breaker problem within the frame.
– If the breaker does not trip, there is probably a defective module or sub–assembly within the shelf.
Verify that the C–CCP shelf breaker on the BTS frame breaker panel is functional.
Use 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.
If everything appears to be correct, visually inspect the power supply module connectors.
Replace the power supply module with a known good module.
If steps 1 through 5 fail to indicate a problem, a C–CCP backplane failure (possibly an open trace) has
occurred.

LPA Module LED
Each LPA module contains a bi–color LED just above the MMI
connector on the front panel of the module. Interpret this LED as
follows:
S GREEN — LPA module is active and is reporting no alarms (Normal
condition).
S Flashing GREEN/RED — LPA module is active but is reporting an
low input power condition. If no BBX is keyed, this is normal and
does not constitute a failure.

The actual rate is 0
NOTE
Defaults for span equalization are 0–131 feet for T1/J1 spans and 120 Ohm for E1.
Default linkspeed is 56K for T1 D4 AMI spans and 64K for all other types.
There is no need to change from defaults unless the OMC–R/CBSC span configuration requires it.
The span configurations loaded in the GLI must match those in the OMCR/CBSC database for the
BTS. If they do not, proceed to Table 6-26.
Repeat steps 1 through 5 for all remaining GLIs.
If the span settings are correct, verify the edlc parameters using the show command.
Any alarm conditions indicate that the span is not operating correctly.
S Try looping back the span line from the DSX panel back to the MM, and verify that the looped
signal is good.
S Listen for control tone on the appropriate timeslot from the Base Site and MM.
Exit the GLI MMI session and HyperTerminal connection by selecting File from the connection
window menu bar, and then Exit from the drop–down menu.
If no TCHs in groomed MCCs (or in whole C–CCP shelf) can process calls, verify that the ISB
cabling is correct and that ISB A and ISB B cables are not swapped.

PN Offset Programming Information
PN Offset Background
All channel elements transmitted from a BTS in a particular 1.25 MHz
CDMA channel are orthonogonally spread by 1 of 128 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 BBXs, 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 B-1.
PN Offset Usage
Only the 14–chip delay is currently in use. It is important to determine
the RF chip delay 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.
NOTE
B-2
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 B-1 to decimal before comparing
them to cdf file I & Q value assignments.
