Update Antenna Mapping Files Earlier release versions may require the antenna.map file to be
updated. There are two antenna mapping files. These are
antenna.map and antenna.asu.
Follow the steps outlined in Table 3-13 to check the antenna mapping
file and update as needed.
Table 3-13: Update Antenna Mapping Files
Step Action
! CAUTION
If you are not familiar with the UNIX vi editor, create a “dummy” CDF file, and practice making
changes to it, prior to altering the “real” one.
NOTE
For more information on file management, creating bts directories, viewing/editing CDF files, refer to
LMF Users Guide, Motorola part no. 68P09226A13.
1View the antenna.map file (see below) and verify the Xcvrs listed in the CDF file (and that are
equipped in the BTS) are also listed in the antenna.map file (for both RX and TX tables). Make
sure the antenna.map file has enough RX and TX antennas listed to cover the number of sectors
indicated by CDF’s SiteConf parameter.

Using CDMA LMF
Jan 2002 3-31
SCt4812ET BTS Optimization/ATP — CDMA LMF
Basic LMF Operation
The terms “CDMA LMF” and “WinLMF” are
interchangeable
NOTE
The CDMA LMF allows the user to work in the two following operating
environments which are accessed using the specified desktop icon:
SGraphical User Interface (GUI) using the WinLMF icon
SCommand Line Interface (CLI) using the WinLMF CLI icon
The GUI is the primary optimization and acceptance testing operating
environment. The CLI environment provides additional capability to the
user to perform manually controlled acceptance tests and audit the
results of optimization and calibration actions.
Basic operation of the LMF GUI includes the following:
SSelecting and deselecting BTS devices
SEnabling devices
SDisabling devices
SResetting devices
SObtaining device status
SSorting a status report window
For detailed information on performing these and other LMF operations,
refer to the CDMA LMF Operator’s Guide, 68P64114A78.
Basic LMF Operation
.
Both the GUI and the CLI use a program known as the handler. Only one
handler can be running at one time. The architectural design is such that
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 that you want to start the application?
This window also contains yes and no buttons. Selecting yes starts the
application. Selecting no terminates the application.

CLI Format Conventions
The CLI command can be broken down in the following way:
SVerb
SDevice including device identifier parameters
SSwitch
SOption parameters consisting of:
–Keywords
–Equals sign (=) between the keyword and the parameter value
–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–<bts_id>–<bbx_id> rssi channel=6 sector=5
Refer to the LMF CLI Commands (68P09251A59) for a complete
explanation of the CLI commands and their usage.
Logging into a BTS
Be sure that the correct bts–#.cdf and cbsc–#.cdf file is
used for the BTS. These should be the CDF files that are
provided for the BTS by the CBSC. Failure to use the
correct CDF files can result in wrong results. Failure to
use the correct CDF files to log into a live (traffic
carrying) site can shut down the site.
IMPORTANT
*
Logging into a BTS establishes a communications link between the BTS
and the CDMA LMF. You may be logged into one or more BTS’s at a
time, but only one LMF may be logged into each BTS.
Before attempting to log into the BTS, confirm the CDMA LMF is
properly connected to the BTS (see Figure 3-4). Follow the procedure in
Table 3-14 to log into a BTS.
Prerequisites
Before attempting to login to a BTS, ensure the following have been
completed:
SThe LMF is correctly installed and prepared.
SA bts-nnn folder with the correct CDF and CBSC file exists.
SThe LMF is correctly installed and prepared, and the LMF computer
was connected to the BTS before starting the Windows operating
system and LMF software. If necessary, restart the computer after
connecting it to the BTS (see Table 3-6 and Figure 3-4).

Overview
Before a BTS can operate, each equipped device must contain device
initialization (ROM) code. ROM code is loaded in all devices during
manufacture, 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 or a normal part of the optimization process. It is only
done in unusual situations where the resident ROM code release level in
the device is not compatible with the required release level of the site
operating software and the CBSC can not communicate with the BTS to
perform the download. An example would be a BTS loaded with R16.0
software where a GLI which is factory–loaded with R9.2.x or earlier
ROM code must be installed to replace a malfunctioning GLI.
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.
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).
Procedures to load ROM code are located in Appendix J.
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 <x>:\<lmf home
directory>\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 loaded will change to OOS_ROM
(blue). When the download is completed successfully, the device will
change to OOS_RAM (yellow).

Download the BTS – continued
Jan 2002 3-39
SCt4812ET BTS Optimization/ATP — CDMA LMF
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–GLI 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:
SMaster Group Line Interface (MGLI)
SRedundant GLI
SClock Synchronization Module (CSM) (Only if new revision code
must be loaded)
SMulti Channel CDMA (MCC24E, MCC8E, or MCC–1X) cards
SBroadband Transceiver (BBX2 or BBX–1X) cards
SRFDS Test Subscriber Interface Card (TSIC) or RFDS–1X RFDS
PROCessor (RPROC) card, if RFDS is installed
The MGLI must be successfully downloaded with RAM
code and data, and in INS_ACT (bright green) status
before downloading any other device. The RAM code
download process for an MGLI automatically downloads
data and then enables the MGLI.
IMPORTANT
*
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 3-19 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
used on the BSS by referring to the Version Matrix section of the
SCt CDMA Release Notes (supplied on the tape or CD–ROM
containing the BSS software).
Table 3-19: Verify GLI ROM Code Loads
Step Action
1If it has not already been done, start a GUI LMF session and log into the BTS ( refer to Table 3-14).

Enable CSMs
Each BTS CSM system features two CSM boards per site. 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
3
Download the BTS – continued
Jan 2002 3-43
SCt4812ET BTS Optimization/ATP — CDMA LMF
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 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 LFR, HSO, or external 10
MHz Rubidium source which the CSM can use as a secondary timing
reference. The HSOX is used for expansion frames. In all cases, the
CSM monitors and determines what reference to use at a given time.
For RF–GPS, verify the CSM configured with the GPS
receiver “daughter board” is installed in the frame’s CSM 1
slot before continuing.
IMPORTANT
*
Follow the steps outlined in Table 3-23 to enable the CSMs installed in
the C–CCP shelves.
Table 3-23: Enable CSMs
Step Action
1Click on the target CSM.
From the Device pull down, select Enable.
NOTE

A status report is displayed confirming change in the device(s) status.
Click OK to close the status report window.
NOTE
FAIL may be shown in the status table for 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.
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).

Clock Synchronization
Manager System Time
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.
Each CSM2 board features an ovenized, crystal oscillator that provides
19.6608 MHz clock, even second pulse, and 3 MHz referenced to the
selected synchronization source (see Table 3-26):
SGPS: local/RF–GPS or remote/R–GPS
SLORAN–C Frequency Receiver (LFR) or High Stability Oscillator
(HSO)
SExternal reference oscillator sources
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 3-26). The source
selection can also be overridden via the LMF or by the system software.
Synchronization between the primary and redundant CSM CCD pairs, as
well as the LFR or HSO back–up to GPS synchronization, increases
reliability.
LFR/HSO
The CSM handles the overall configuration and status monitoring
functions of the LFR/HSO. In the event of GPS failure, the LFR/HSO is
capable of maintaining synchronization initially established by the GPS
reference signal.
The LFR requires an active external antenna to receive LORAN 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 indefinately after initial GPS lock.

SCt4812ET BTS Optimization/ATP — CDMA LMF Jan 2002

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 frames. The associated expansion 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 3-26). HSO, HSO2, and
HSOX use the same source code in source selection (see Table 3-26).
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.

SCt4812ET BTS Optimization/ATP — CDMA LMF
Equipment Warm-up
Warm-up BTS equipment for a minimum of 60 minutes
prior to performing the BTS optimization procedure. This
assures BTS stability and contributes to optimization
accuracy.
–Time spent running initial or normal power-up,
hardware/firmware audit, and BTS download counts
as warm-up time.
IMPORTANT
*
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 BBX under test OOS.
Failure to do so can result in serious personal injury
and/or equipment damage.
WARNING
Automatic Cable Calibration
Set–up
Figure 3-9 and Figure 3-10 show the cable calibration setup for the test
sets supported by the LMF. The left side of the diagram depicts the
location of the input and output connectors of each test equipment item,
and the right side details the connections for each test. Table 3-33
provides a procedure for performing automatic cable calibration.
Manual Cable Calibration
If manual cable calibration is required, refer to the procedures in
Appendix F.

Test Set Calibration
Jan 2002 3-73
SCt4812ET 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.

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.
Selecting Test Equipment
Use LMF Options from the Options menu list to select test equipment
automatically (using the autodetect feature) or manually.
Prerequisites
A Serial Connection and a Network Connection tab are provided for
test equipment selection. The Serial Connection tab is used when the
test equipment items are connected directly to the CDMA LMF
computer via a GPIB box (normal setup). The Network Connection tab
is used when the test equipment is to be connected remotely via a
network connection.
Ensure the following has been completed before selecting test
equipment:
STest equipment is correctly connected and turned on.
SCDMA LMF computer serial port and test equipment are connected to
the GPIB box.
Manually Selecting Test
Equipment in a Serial
Connection Tab
Test equipment can be manually specified before, or after, the test
equipment is connected. CDMA LMF does not check to see if the test
equipment is actually detected for manual specification.

search box will be used for RF power measurements (i.e., TX calibration). The address for a signal
generator is normally 1, a power meter is normally 13 and the address for a CDMA analyzer is
normally 18. If 1, 13,18 are included in the GPIB addresses to search box, the power meter (13) will
be used for RF power measurements. If the test equipment items are manually selected the CDMA
analyzer is used only if a power meter is not selected.
6 Click Apply. The button will darken until the selection has been committed. A check mark will
appear in the Manual Configuration section for detected test equipment items.

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.
Calibrate Test Equipment from the Util menu list is used to calibrate
test equipment item before being used for testing. The test equipment
must be selected before beginning calibration. Follow the procedure in
Table 3-32 to calibrate the test equipment.
Table 3-32: Test Equipment Calibration
Step Action
1From the Util menu, select Calibrate Test Equipment. A Directions window is displayed. Follow
the instructions provided.
2Follow the direction provided.
3Click on Continue to close the Directions window. A status window is displayed.
4Click on OK to close the status report window.
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 procedures.
SMeasure the loss of a short cable. This is done to compensate for any
measurement error of the analyzer. The short 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.
SMeasure the 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.
SMeasure the 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 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.

Bay Level Offset Calibration
Jan 2002 3-83
SCt4812ET BTS Optimization/ATP — CDMA LMF
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 (BBX
slot) at the BTS site and stores that value in the CAL file. The BLOs are
subsequently downloaded to each BBX.
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 LPA, and terminates at a BTS TX antenna port.
Calibration identifies the accumulated gain in every transmit path (BBX
slot) at the BTS site and stores that value in the CAL file. Each transmit
path starts at a C–CCP shelf backplane BBX 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.
When to 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:
SBBX 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 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).

SCt4812ET BTS Optimization/ATP — CDMA LMF
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 BBXs 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 BBX slots. Slot 20
contains the calibration data for the redundant BBX (see Table 3-39).
Each BBX 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 BBX is organized as a large flat array. The
array is organized by branch, BBX slot, 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:

SThe 20 calibration entries for each slot/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 BBX is loaded with BLO 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[60]. BBX slot 1’s 10 calibration
points are sent (C[1] – C[20]), followed by BBX slot 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.
Test Equipment Setup:
RF Path Calibration
Follow the steps in Table 3-40 to set up test equipment.
Table 3-40: Test Equipment Setup (RF Path Calibration)
Step Action
NOTE
Verify the GPIB 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 or via a 30 dB coupler with a 20 dB in–line attenuator for 1900 MHz.
1Connect the LMF computer terminal to the BTS LAN A connector on the BTS (if you have not
already done so). Refer to the procedure in Table 3-6.
SIf required, calibrate the test equipment per the procedure in Table 3-32.

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 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).
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.
SAt 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.
SExample: 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.
The LMF Tests menu list items, TX Calibration and All Cal/Audit,
perform the TX BLO Calibration test for a XCVR(s). The All Cal/Audit
menu item performs TX calibration, downloads BLO, and performs TX
audit if the TX calibration passes. All measurements are made through
the appropriate TX output connector using the calibrated TX cable setup.
Test Pattern Drop–down Pick List
Pilot is shown as the default setting in this pick list box. The full range
of available selections and their descriptions are as follows:
Standard – performs calibration or audit using pilot, paging, synch, and
six traffic channels with IS–97–specified gain. This pattern setting
should be used for all non–in–service calibrations and audits. Using this
pattern setting requires the selection of both a BBX and at least one
MCC.
Pilot (default) – performs calibration using only the pilot channel. This
pattern setting should be used for in–service calibrations, and requires
selection of only a BBX.
CDFPilot –This pattern setting is for advanced users. It performs
calibration or audit using the CDF value for pilot gain and IS–97 gain
values for all the other channels included in the Standard pattern setting
(paging, synch, and six traffic). Using this pattern setting requires the
selection of both a BBX and at least one MCC.

CDF – This pattern setting is for advanced users who need to use CDF
gain settings for all channels included in the Standard pattern setting
(pilot, paging, synch, and six traffic). Using this pattern setting requires
the selection of both a BBX and at least one MCC.
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
Normally valid values are some value plus–or–minus some offset. If
single–sided BLO” is selected, the result will only be considered a
success if it’s in the lower half of the range. If it was normally success
from 37–47 (which is 42± 5), single–sided BLO” would make it a
success only if the result was from 37–42.
Prerequisites
Before running this test, ensure that the following have been done:
SCSM–1, GLIs, MCCs, and BBXs have correct code load and data
load.
SPrimary CSM and MGLI are INS.
SAll BBXs are OOS_RAM.
STest equipment and test cables are calibrated and connected for TX
BLO calibration.
SLMF is logged into the BTS.
Connect the test equipment as shown in Figure 3-11 and Figure 3-12 and
follow the procedure in Table 3-41 to perform the TX calibration test.
Before installing any test equipment directly to any TX
OUT connector, first verify there are no CDMA BBX
channels keyed. Failure to do so can result in serious
personal injury and/or equipment damage.

RFDS Description
The optional RFDS is used to perform RF tests of the site from the
CBSC or from the LMF. The RFDS contains the following FRUs:
SAntenna Select Unit (ASU)
SFixed Wireless Terminal Interface Card (FWTIC)
SSubscriber Unit Assembly (SUA)
For complete information regarding the RFDS, refer to the CDMA
CDMA RFDS Hardware Installation; 68P64113A93, CDMA RFDS
User’s Guide; 68P64114A51, and the LMF Help function on–line
documentation.
RFDS Parameters
The bts–#.cdf file includes RFDS parameter settings that must match the
installed RFDS equipment. The paragraphs below describe the editable
parameters and their defaults. Table 3-46 explains how to edit the
parameter settings.
SRfdsEquip – valid inputs are 0 through 2.
0 = (default) RFDS is not equipped
1 = Non-Cobra/Patzer box RFDS
2 = Cobra RFDS
STsuEquip – valid inputs are 0 or 1
0 = (default) TSU not equipped
1 = TSU is equipped in the system
SMC1....4 – valid inputs are 0 or 1
0 = (default) Not equipped
1 = Multicouplers equipped in RFDS system
(SC9600 internal RFDS only)
SAsu1/2Equip – valid inputs are 0 or 1
0 = (default) Not equipped
1 = Equipped
STestOrigDN – valid inputs are ’’’ (default) or a numerical string up to
15 characters. (This is the phone number the RFDS dials when
originating a call. A dummy number needs to be set up by the switch,
and is to be used in this field.)
Any text editor may be used to open the bts–#.cdf file to
verify, view, or modify data. Because the bts–#.cdf file is
generated on a Unix system, a more sophisticated editor,
such as MicroSoft WordPad, will display file content in a
more easily–read format than many simple text editors.

RFDS Setup and Calibration – continued
Jan 2002 3-105
SCt4812ET BTS Optimization/ATP — CDMA LMF
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 3-51.
Table 3-51: RFDS TSIC Calibration Channel Frequencies
System Channel Calibration Points
800 MHz (A and B) 341 and 682
1.9 GHz 408 and 791
Before installing any test equipment directly to any TX
OUT connector, verify that there are no CDMA channels
keyed. Failure to do so can result in serious personal injury
and/or equipment damage.

Alarms Testing
SCt4812ET BTS Optimization/ATP — CDMA LMF Jan 2002
3-108
Alarm Verification
The alarms testing should be performed at a convenient point in the
optimization/ATP process, since the 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.
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,

Automated Acceptance Test Procedures – Overview
Jan 2002 4-1
SCt4812ET BTS Optimization/ATP — CDMA LMF
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.
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.
Before using the LMF, use an editor to view the
”CAVEATS” section in the ”readme.txt” file in the c:\wlmf
folder for any applicable information.
The ATP test is to be performed on out-of-service sectors
only.
DO NOT substitute test equipment with other models not
supported by the LMF.

Reduced ATP
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.
NOTE
After downloading the proper operational software to the BTS, the
Cellular Field Engineer (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 section (Table B-1)
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.
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, BBX, and CIO 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), CIO, BBX, 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.

ATP Test Prerequisites
Before attempting to run any ATP tests, ensure the following:
SBTS has been optimized and calibrated (see Chapter 3).
SLMF is logged into the BTS.
SCSMs, GLI2s, BBXs, MCCs and TSU (if the RFDS is installed)have
correct code load and data load
SPrimary CSM and GLI2 are INS_ACT
SMCCs are INS_ACT.
SBBXs are OOS-RAM.
SBBXs are calibrated and BLOs are downloaded.
STest cables are calibrated.
STest equipment is selected.
STest equipment is connected for ATP tests.
STest equipment has been warmed up 60 minutes and calibrated.
SGPIB is on.
Before the FER is run, be sure that all LPAs 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.
WARNING
TX/RX OUT Connections
Many of the acceptance test procedures require taking
measurements at the TX OUT (BTS/RFDS) connector. At
sites with RFDS, all measurements are through the RFDS
directional coupler TX OUT connector.

SCt4812ET BTS Optimization/ATP — CDMA LMF
Individual Acceptance Tests The following individual 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 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 .
Frame Error Rate

TX Spectral Purity Transmit Mask Acceptance Test
Jan 2002 4-7
SCt4812ET BTS Optimization/ATP — CDMA LMF
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:
S1.9 GHz
–at least –45 dB @ + 900 kHz from center frequency
–at least –45 dB @ – 900 kHz from center frequency
S800 MHz:
–at least –45 dB @ + 750 kHz from center frequencY
–at least –45 dB @ – 750 kHz from center frequency
–at least –60 dB @ – 1980 kHz from center frequency
–at least –60 dB @ – 1980 kHz from center frequency
The BBX2 then de-keys, and, if selected, the MCC is re-configured to
assign the applicable redundant BBX2 to the current TX antenna path
under test. The test is then repeated.

TX Waveform Quality (rho) Acceptance Test
Jan 2002 4-9
SCt4812ET BTS Optimization/ATP — CDMA LMF
Background: Rho Test
This test verifies the transmitted Pilot channel element digital waveform
quality 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.
The Pilot Gain is set to 262 for each antenna, and all channel elements
from the MCCs will be 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, Walsh code 0). BBX2 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
channel element digital waveform quality (rho) in dB, verifying that
result meets system tolerances Waveform quality (rho) should
be > 0.912 (–0.4 dB).
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, Rho, performs the waveform quality test
for a XCVR(s). All measurements are made through the appropriate TX
output connector using the calibrated TX cable setup.

TX Pilot Time Offset Acceptance Test
SCt4812ET BTS Optimization/ATP — CDMA LMF Jan 2002
4-10
Background: Pilot Offset
Acceptance Test
This test verifies the transmitted Pilot channel element Pilot Time Offset
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
will be 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 uS, verifying results meet system tolerances: Pilot Time
Offset should be within < 3 µs of the target PT Offset (0 mS).
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.

TX Code Domain Power Acceptance Test
Jan 2002 4-11
SCt4812ET BTS Optimization/ATP — CDMA LMF
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).
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.
Upon completion of the test, OCNS is disabled on the specified
MCC/CE.

RX Frame Error Rate (FER) Acceptance Test
Jan 2002 4-13
SCt4812ET BTS Optimization/ATP — CDMA LMF
Background: FER Test
This test verifies the BTS FER on all traffic channel elements currently
configured on all equipped MCCs (full rate at 1% FER) at an RF input
level of –119 dBm [or –116 dBm if using Tower Top Amplifier
(TMPC)]. All tests are performed using the external calibrated test set as
the signal source controlled by the same command. All measurements
will be via the LMF.
The pilot gain is set to 262 for each TX antenna and all channel elements
from the MCCs are forward-link disabled. The BBX2 is keyed up using
only bbxlvl level offsets, to generate a CDMA carrier (with pilot channel
element only). BBX2 power output is set to –20 dBm as measured at the
TX OUT connector (on either the BTS or RFDS directional coupler).
The BBX2 must be keyed in order to enable the RX receive circuitry.
The LMF prompts the MCC/CE under test to measure all zero longcode
and provide the FER report on the selected active MCC on the reverse
link for both the main and diversity RX antenna paths, verifying the
results meet the following specification: FER returned less than 1% and
total frames measured is 1500.
All MCC/CEs selected are tested on the specified RX antenna path. The
BBX then de-keys and, the applicable redundant BBX2 is assigned to
the current RX antenna paths under test. The test is then repeated.
