Preliminary Operations: Overview
Introduction
This section first verifies proper frame equipage against the site-specific
documentation supplied for each BTS application.
Cicruit Backhaul Operation
If circuit backhaul operation is being used, perform the procedures
described in this chapter. Refer to the LMF Help, if further information
is needed.
Packet Backhaul Operation
If packet backhaul configuration is being used, perform the procedures
described in Appendix I.
Peform the IBR procedures described in Appendix G and Appendix H if
GLI3 data load and span parameters need to be verified.
Cell–site Types
The site is configured as Omni with one carrier. The BTS can handle two
carriers.
CDF/NECF
The Configuration Data File (CDF) or Network Element Configuration
File (NECF) contains information that defines the BTS and data used to
download files to the devices. The BTS CDF (bts–#.cdf) and CBSC
CDF (cbsc–#.cdf ) files are used by circuit BTSs. The NEC Base
(NECB – NECB*bts#.xml ) and NEC Journaling (NECJ–
NECJ*bts#.xml ) files are used by packet BTSs. CDF or NEC files
must be placed in the applicable BTS folder before the LMF can be used
to log into that BTS. CDF and NEC files are normally obtained from the
CBSC using a floppy disk. A file transfer protocol (ftp) method can be
used if the LMF computer has that capability.
The CDF and NEC files include the following information:
S Download instructions and protocol
S Site specific equipage information
S CCP2 Shelf allocation plan
– BBX equipage
– CSA equipage
– MCC–1X (16, 24,32, 64) channel element allocation plan. This plan

Introduction to Optimization and Calibration
Overview
This section describes procedures for isolating the BTS from the span
lines, preparing and using the WinLMF, downloading system operating
software, CSA reference verification/optimization, set up and calibration
of the supported test equipment, and transmit/receive paths are
functioning properly.
NOTE
Before using the WinLMF, use an editor to view the
“CAVEATS” section in the “readme.txt” file in the c:\wlmf
folder for any applicable information.
Optimization Process
Summary
After a BTS is physically installed and the preliminary operations, such
as power up, have been completed, the WinLMF is used to optimize the
BTS. The basic optimization process consists of the following:
1. Download GLI3 (GLI–bts#–1) with application code and data and
then enable GLI3.
2. Use the WinLMF status function and verify that all of the installed
devices of the following types respond with status information:
CSA, BBX, GLI3, and MCC. If a device is installed and powered up
but is not responding and is colored gray in the BTS display, the
device is not listed in the CDF file. The CDF/NECF file must be
corrected before the device can be accessed by the WinLMF.
3. Download device application code and data to all devices of the
following types:
– CSA
– BBX–1X
– MCC–1X
4. Verify the operation of the GPS and HSO/MSO signals.
5. Using the WinLMF test equipment selection function, select the test
equipment to be used for the calibration.
6. Calibrate the TX and RX test cables if they have not previously been
calibrated with the WinLMF computer and software build which will
be used for the optimization/calibration. Cable calibration values can
be entered manually, if required.
7. Connect the required test equipment for a full optimization.
8. Select all of the BBXs and all of the MCCs and use the full
optimization function. The full optimization function performs TX
calibration, BLO download, TX audit, all TX tests, and all RX tests
for all selected devices.
9. If the TX calibration fails, repeat the full optimization for any failed
paths.

Introduction to Optimization and Calibration
– continued
10. If the TX calibration fails again, troubleshoot and correct the
problem causing the failure, and repeat the full optimization for the
failed path.
11. If the TX calibration and audit portion of the full optimization passes
for a path but some of the TX or RX tests fail, troubleshoot and
correct the problem causing the failure, and run the individual tests
as required until all TX and RX tests have passed for all paths.
Cell-site Types
The site is configured as Omni/Omni. Each cell site type has unique
characteristics and must be optimized accordingly.
CDF/NECF
The CDF/NECF (Configuration Data File/Network Element
Configuration File) contains information that defines the BTS and data
used to download files to the devices. A CDF/NECF file must be placed
in the applicable BTS folder before the WinLMF can be used to log into
that BTS. CDF/NECF files are normally obtained from the CBSC using
a floppy disk. A file transfer protocol (ftp) method can be used if the
WinLMF computer has that capability. Refer to the WinLMF Help
function on–line documentation for more information.
The CDF/NECF includes the following information:
S Download instructions and protocol
S Site specific equipage information
S CCP2 Shelf allocation plan
– BBX equipage (based on cell–site type) including IS–95A/B or
CDMA2000 1X capability and redundancy
– CSA equipage including redundancy
– Multi–Channel CDMA Card 1X channel element allocation plan.
This plan indicates how the CCP2 Shelf is configured, and how the
paging, synchronization, traffic, and access channel elements (and
associated gain values) are assigned among the (up to 3) MCC–1Xs
in the shelf.
S Effective Rated Power (ERP) table for all TX channels to antennas
respectively. Motorola System Engineering specifies the ERP of a
transmit antenna based on site geography, antenna placement, and
government regulations. Working from this ERP requirement, antenna
gain and antenna feed line loss can be combined to calculate the
required transmit power at the frame antenna connections. The
corresponding BBX output power required to achieve that power level
on any channel/sector can then be determined based on Bay Level
Offset (BLO) data established during the optimization process.

NOTE
Refer to Figure 6-2 and the WinLMF Help function on–line
documentation for additional information on the layout of
the WinLMF directory structure (including CDF/NECF file
locations and formats).
BTS System Software
Download
BTS system software must be successfully downloaded to the BTS
processor boards before optimization can be performed. BTS operating
code is loaded from the WinLMF computer terminal.
The BTS is configured for Circuit Backhaul and uses bts.cdf files. BTSs
configured for Packet Backhaul use bts.necf files (bts–xxx.xml) located
on the OMC–R.
NOTE
Before using the WinLMF for optimization/ATP, the
correct bts–#.cdf (or bts–#.necf) and cbsc–#.cdf files for
the BTS must be obtained from the CBSC and put in a
bts–# folder in the WinLMF. Failure to use the correct
CDF/NECF files can cause wrong results. Failure to use
the correct CDF/NECF files to log into a live (traffic
carrying) site can shut down the site.
The CDF/NECF is normally obtained from the CBSC on a DOS
formatted diskette, or through a file transfer protocol (ftp) if the
WinLMF computer has ftp capability. Refer to the WinLMF Help
function on–line documentation for the procedure.
Site Equipage Verification
If you have not already done so, use an editor to view the CDF/NECF,
and review the site documentation. Verify the site engineering equipage
data in the CDF/NECF matches the actual site hardware using a
CDF/NECF conversion table.
CAUTION
Use extreme care not to make any changes to the
CDF/NECF content while viewing the file. Changes to the
CDF/NECF can cause the site to operate unreliably or
render it incapable of operation.
Always wear a conductive, high impedance wrist strap
while handling any circuit card/module to prevent damage
by ESD. Extreme care should be taken during the removal
and installation of any card/module. After removal, the
card/module should be placed on a conductive surface or
back into the anti–static bag in which it was shipped.

Overview of Packet BTS files
R16.0 and earlier releases had the configuration file called CDF for each
BTS and CBSC used by WinLMF. In 16.1 Packet BTS, BTS with GLI3
booting in packet binary, the CDF is replaced by two new configuration
files called Network Element Configuration Base (NECB) and Network
Element Change Journal (NECJ). The NECB contains the baseline
configuration and is analogous to the CDF, while the NECJ contains all
the changes made to the configuration since the last time the NECB was
re–generated. Once the NECJ gets to 80% of its maximum size, the
NECB is re–generated and all the updates are rolled into it.
These files play much broader and vital role than previous CDF files.
GLI3 booting in circuit binaries works similar to R16.0.
A few WinLMF related important facts about these files are listed below.
S Both files (NECB and NECJ) are in XML format.
S NECB contains all the up-to-date static configuration information and
NECJ contains all the recent changes (including operations) which are
not updated in the NECB.
S Both files can be viewed in any XML viewer (most easily available is
Internet Explorer V5.0 and higher). They can be also viewed by any
other word processor, but the XML tags will also be seen with them.
S These files will be created by OMC–R from MIB as per the BTS
provisioning.
S These files will be regenerated for each software release upgrade on
the system for each BTS.
S These files will reside on both OMC–R and Packet–GLI3 (unlike
CDF) and will be synchronized periodically between them.
S Both NECB and NECJ file contain a “SoftwareVersion” field in their
header section indicating the system release version of these files.
S Instead of the bts#.cdf file, the packet WinLMF uses a bts#.XML file,
which is a copy of the NECB.XML file.
S Packet–GLI3 will need these files for site initialization.
S The scope of NECB has grown much broader than CDF and has much
more BTS centric information. The use of generic version of these
files should be strictly avoided for the correct site initialization.

WinLMF Features and
Installation Requirements
Before optimization can be performed, the WinLMF application software
must be installed and configured on a computer platform meeting
Motorola–specified requirements.
NOTE
For the WinLMF graphics to display properly, the
computer platform must be configured to display more
than 256 colors. See the operating system software
instructions for verifying and configuring the display
settings.
Software and files for installing and updating the WinLMF are provided
on CD ROM disks. The following items must be available:
S WinLMF application program on CD ROM
S CDF/NECF for each supported BTS (on diskette or available from the
CBSC)
S CBSC File for each supported BTS (on floppy disk or CD ROM)
FTP Server
To be able to download files to the GLI3, the WinLMF now runs FTP
server on the WinLMF laptop. The WinLMF FTP server runs from the
LMFs home directory. All the files necessary to run the WinLMF FTP
server are installed from the WinLMF CD. The FTP server is
automatically started by the WinLMF upon successful Login to a Packet
BTS.
In addition, the WinLMF provides a new option in the Tools menu called
FTP Server. The option starts the LMFs FTP server if Start is selected,
and stops the server if Stop is selected. The LMFs FTP server runs on
port 21. If any other process is using that port, the error message is
displayed to the user stating that the port is occupied. There is another
option under FTP Server menu called FTP Monitor, which allows the
user to watch FTP activity b/w the WinLMF and GLI.
Firewalls
Firewalls will block the FTP requests from the Packet GLI to the
WinLMF laptop. You must disable your firewall before attempting the
BTS Synch command. Some common firewall programs to look for
include Network ICE, BlackICE, Norton’s Desktop Firewall, Enterprise
Firewall, and Personal Firewall.

FTP Server Port in use
On some Windows 2000 installations, a process called “inetd.exe”
makes the FTP server port 21 unusable by the WinLMF. If the WinLMF
reports that the FTP server could not start because the port is in use,
make sure the inetd.exe is not running by using the Task Manager’s
process list. If inetd.exe is running, end the process by selecting it and
clicking the “End Process” button. Inetd32.exe is NOT the same and
ending it will not resolve this problem.
WinLMF File Structure
Overview
The WinLMF uses a :\ folder that contains all
of the essential data for installing and maintaining the BTS. The
following list outlines the folder structure for WinLMF. Except for the
bts-nnn folders, these folders are created as part of the WinLMF
installation. Refer to the CDMA WinLMF Operator’s Guide for a
complete description of the folder structure.
Figure 6-2: WinLMF Folder Structure
(C:)
x:\ folder
cdma folder
BTS–nnn folders (A separate folder is
required for each BTS where bts–nnn is the
unique BTS number; for example, bts–163.)
loads folder
version folder (A separate folder is
required for each different version; for
example, a folder name 2.8.1.1.1.5.)
code folder
data folder
NOTE
The “loads” folder and all the folders below it are not
available from the WinLMF for Software Release 2.16.3.x.
These folders may be present as as a legacy from previous
software versions or downloaded from the OMC–R/CBSC.
WinLMF Home Directory
The WinLMF installation program creates the default home directory,
c:\wlmf, and installs the application files and subdirectories (folders)
in it. Because this can be changed at installation, the CDMA WinLMF
home directory will be referred to with the generic convention of:

:\
Where:
= the WinLMF computer drive letter where the CDMA WinLMF
home directory is located.
= the directory path or name where the CDMA
WinLMF is installed.
NECF Filename Conventions
and Directory Location
NECF
The NECF actually consists of two files: the NECB and NECJ. The
naming convention for the NECB and NECJ is:
NECB*bts#.xml
NECJ*bts#.xml
Where:
* = any characters can be substituted there
# = the actual integer BTS number
The NECB and its corresponding NECJ must have the exact same name,
except for the “B” and “J” difference after the initial NEC characters.
The NECB and the NECJ must reside in the
\cdma\bts–# directory corresponding to the BTS
frame they are for.
Load Information File (LIF)
The LIF contains all the devices binaries available for the specified
System Software Release. It is the functional equivalent of the OLF file
that was used pre–Packet.
The naming convention for the LIF is:
NE_LIF.xml
The LIF must reside in the \cdma\loads\ directory, where = the home
directory in which the WinLMF is installed, usually C:\wlmf = the System Software Release Number (e.g.
2.16.1.0.10).
Cal File
The Cal File still resides in the \cdma\bts–#
directory and is named bts–#.cal, where # is the actual integer number of
the BTS.

First Time Installation Sequence
Install Java Runtime Environment (JRE)
Install U/WIN K–shell emulator
Install WinLMF application programs
Install/create BTS folders
NOTE
Any time you install U/WIN, you must install the
WinLMF software because the installation of the WinLMF
modifies some of the files that are installed during the
U/Win installation. Installing U/Win over–writes these
modifications.
There are multiple binary image packages for installation
on the CD–ROM. When prompted, choose the load that
corresponds to the switch release that you currently have
installed. Perform the Device Images install after the
WinLMF installation.
If applicable, a separate CD ROM of BTS Binaries may be
available for binary updates.

Copy BTS CDF (or NECF) and
CBSC CDF Files to the WinLMF
Computer
Before logging on to a BTS with the WinLMF computer to execute
optimization/ATP procedures, the correct bts-#.cdf (or bts–#.necf) and
cbsc-#.cdf files must be obtained from the CBSC and put in a bts-#
folder in the WinLMF computer. This requires creating versions of the
CBSC CDF files on a DOS–formatted floppy diskette and using the
diskette to install the CDF files on the WinLMF computer.
NOTE
If the WinLMF has ftp capability, the ftp method can be
used to copy the CDF or NECF files from the CBSC.
On Sun OS workstations, the unix2dos command can be
used in place of the cp command (e.g., unix2dos
bts–248.cdf bts–248.cdf). This should be done using a
copy of the CBSC CDF file so the original CBSC CDF file
is not changed to DOS format.
When copying CDF or NECF files, comply with the
following to prevent BTS login problems with the
Windows WinLMF:
– The numbers used in the bts-#.cdf (or bts–#.necf)
and cbsc-#.cdf filenames must correspond to the
locally-assigned numbers for each BTS and its
controlling CBSC.
– The generic cbsc–1.cdf file supplied with the
Windows WinLMF will work with locally numbered
BTS CDF files. Using this file will not provide a
valid optimization unless the generic file is edited to
replace default parameters (e.g., channel numbers)
with the operational parameters used locally.
The procedure in Table 6-3 lists the steps required to transfer the CDF
files from the CBSC to the WinLMF computer. For further information,
refer to the WinLMF Help function on–line documentation.

Action
Type mount and press the Enter key.
NOTE
S Look for the “floppy/no_name” message on the last line displayed.
S If the eject command was previously entered, floppy/no_name will be appended with a number.
Use the explicit floppy/no_name reference displayed when performing step 7.
Change to the directory, where the files to be copied reside, by typing cd
(e.g., cd bts–248) and pressing the Enter key.
Type ls and press the Enter key to display the list of files in the directory.
With Solaris versions of Unix, create DOS–formatted versions of the bts-#.cdf (or bts–#.necf) and
cbsc-#.cdf files on the diskette by entering the following command:
unix2dos /floppy/no_name/
(e.g., unix2dos bts–248.cdf /floppy/no_name/bts–248.cdf).
NOTE
S Other versions of Unix do not support the unix2dos and dos2unix commands. In these cases, use
the Unix cp (copy) command. The copied files will be difficult to read with a DOS or Windows text
editor because Unix files do not contain line feed characters. Editing copied CDF files on the
WinLMF computer is, therefore, not recommended.
S Using cp, multiple files can be copied in one operation by separating each filename to be copied
with a space and ensuring the destination directory (floppy/no_name) is listed at the end of the
command string following a space (e.g., cp bts–248.cdf cbsc–6.cdf /floppy/no_name).
Repeat Steps 5 through 7 for each bts–# that must be supported by the WinLMF computer.
When all required files have been copied to the diskette type eject and press the Enter key.

Remove the diskette from the CBSC drive.
AT THE WinLMF:
11
If it is not running, start the Windows operating system on the WinLMF computer.
12
Insert the diskette containing the bts-#.cdf (or bts–#.necf) and cbsc-#.cdf files into the WinLMF
computer.
13
Using MS Windows Explorer, create a corresponding bts–# folder in the :\\cdma directory for each bts–#.cdf/cbsc–#.cdf (or bts–#.necf/cbsc–#.cdf) file pair copied
from the CBSC.
14
Use MS Windows Explorer to transfer the bts-#.cdf (or bts–#.necf) and cbsc-#.cdf files from the
diskette to the corresponding :\\cdma\bts–# folders created in Step 13.

Creating a Named
HyperTerminal Connection for
MMI Communication
Confirming or changing the configuration data of certain BTS Field
Replaceable Units (FRU) requires establishing an MMI communication
session between the WinLMF and the FRU. Using features of the
Windows operating system, the connection properties for an MMI
session can be saved on the WinLMF computer as a named Windows
HyperTerminal connection. This eliminates the need for setting up
connection parameters each time an MMI session is required to support
optimization.
Once the named connection is saved, a shortcut for it can be created on
the Windows desktop. Double–clicking the shortcut icon will start the
connection without the need to negotiate multiple menu levels.
Follow the procedures in Table 6-4 to establish a named HyperTerminal
connection and create a Windows desktop shortcut for it.

Span Lines – Interface and Isolation
T1/E1 Span Interface
NOTE
At active sites, the OMC–R/CBSC must disable the BTS
and place it out–of–service (OOS). DO NOT remove the
span line cable connectors until the OMC–R/CBSC has
disabled the BTS.
Before connecting the WinLMF computer to the BTS LAN, the
OMC–R/CBSC must disable the BTS and place it OOS. This will allow
the WinLMF to control the BTS, and prevent the CBSC from
inadvertently sending control information to the BTS during
WinLMF–based tests.
Isolate BTS from T1/E1 Spans
Once the OMC–R/CBSC has disabled the BTS, the spans must be
disabled to ensure the WinLMF will maintain control of the BTS.
T1/E1 Span Isolation
Table 6-5 describes the action required for span isolation.
Table 6-5: T1/E1 Span Isolation

Using the LMF
Basic LMF Operation
LMF Coverage in This Publication – The LMF application program
supports maintenance of both CDMA and SAS BTSs. All references to
the LMF in this publication are to the CDMA portion of the program.
Operating Environments – The LMF application program allows the
user to work in the two following operating environments which are
accessed using the specified desktop icons:
S Graphical User Interface (GUI) using the WinLMF icon
S Command Line Interface (CLI) using the WinLMF CDMA 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 – Basic operation of the LMF in either environment
includes performing the following:
Selecting and deselecting BTS devices
Enabling devices
Disabling devices
Resetting devices
Obtaining device status
The following additional basic operation can be performed in a GUI
environment:
S Sorting a status report window
For detailed information on performing these and other LMF operations,
refer to the LMF Help function on–line documentation.
NOTE
Unless otherwise noted, LMF procedures in this manual
are performed using the GUI environment.

The LMF Display and the BTS
BTS Display – When the LMF is logged into a BTS, a frame tab is
displayed for each BTS frames. The frame tab will be labeled with
“CDMA” and the BTS number, a dash, and the frame number (for
example, BTS–812–1 for BTS 812, RFMF 1). If there is only one frame
for the BTS, there will only be one tab.
CDF/NECF Requirements – For the LMF to recognize the devices
installed in the BTS, a BTS CDF/NECF file which includes equipage
information for all the devices in the BTS must be located in the
applicable :\\cdma\bts–# folder. To provide
the necessary channel assignment data for BTS operation, a CBSC CDF
file which includes channel data for all BTS RFMFs is also required in
the folder.
Graphical User Interface
Overview
The LMF uses a GUI, which works in the following way:
S Select the device or devices.
S Select the action to apply to the selected device(s).
S While action is in progress, a status report window displays the action
taking place and other status information.
S The status report window indicates when the the action is complete
and displays other pertinent information.
S Clicking the OK button closes the status report window.
Understanding GUI Operation
The following screen captures are provided to help understand how the
GUI operates:
– Figure 6-4 depicts the differences between packet and circuit
CDMA “cdf” file identification. Note that if there is a packet
version “bts” file, the “(P)” is added as a suffix. There is a
corresponding “(C)” for the circuit mode version.
– Figure 6-5 depicts the Self-Managed Network Elements (NEs) state
of a packet mode. Note that an “X” is on the front of each card that
is under Self–Managed Network Elements (NEs) control by the
GLI3 card.
– Figure 6-6 depicts three of the available packet mode commands.
Normally the GLI3 has Self-Managed Network Elements (NEs)
control of all cards as shown in Figure 6-5 by an “(X)”. In that state
the LMF may only status a card. In order to download code or test a
card, the LMF must request Self-Managed Network Elements (NEs)
control of the card by using the shown dropdown menu. It also uses
this menu to release control of the card back to the GLI3. The GLI3
will also assume control of the cards after the LMF logs out of the
BTS. The packet mode GLI3 normally is loaded with a tape release
MAY 2004

and NECB and NECJ files which point to a tape release stored on
the GLI3. When the GLI3 has control of a card it will maintain that
card with the code on that tape release.
– Figure 6-7 depicts a packet mode site that has the MCC–1 and the
BBX–1 cards under LMF control. Notice that the “X” is missing
from the front of these two cards.
For detailed information on performing these and other LMF operations,
refer to the LMF Help function on–line documentation.

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. 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:
Verb
Device including device identifier parameters
Switch
Option 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–– rssi channel=6 sector=5
Refer to the 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 6-6 and Figure 6-3.
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.

Pinging the BTS
For proper operation, the integrity of the Ethernet LAN A and B links
must be verified. Figure 6-10 represents a typical BTS Ethernet
configuration. The drawing depicts cabling and termination for both the
A and B LANs.
Ping is a program that sends request data packets to hosts on a network,
in this case GLI modules on the BTS LAN, to obtain a response from the
“target” host specified by an IP address.
Follow the steps in Table 6-12 to ping each processor (on both LAN A
and LAN B) and verify LAN redundancy is working properly.
CAUTION
Always wear an approved anti–static wrist strap while handling
any circuit card/module to prevent damage by ESD.

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, 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.
If you must download ROM code, the procedures are located in

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 Base Station System
(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.

* IMPORTANT
– The GPS satellite system satellites are not in a geosynchronous orbit and are maintained and
operated by the United States Department of Defense (DOD). The DOD 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 CSA 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).

CSA System Time – GPS & HSO/MSO Verification
Clock Synchronization and
Alarm (CSA) Sub–system
Description
Overview
The primary function of the CSA card is to maintain CDMA system
time. A GPS receiver provides the primary timing reference for all
CDMA BTS’s During normal operation, the CSA clocking outputs are
phase locked to the GPS receiver timing reference. The CSA supports
either an on–board GPS receiver module (RF GPS) or Remote GPS
(RGPS) receiver. The RGPS receiver consists of a combined GPS
receiver and antenna witha digital interface to the CSA.
Backup Timing References
Timing signals from the High Stability Oscillator (HSO) or Medium
Stability Oscillator (MSO) are used in the event that the primary (GPS)
reference should become unavailable. The HSO or MSO clock is
calibrated against the GPS timing signal when a valid GPS timing signal
is available to provide the longest possible backup timing performance.
The CSA continuously monitors each available timing reference and
utilizes the most suited reference to maintain system synchronization.
Timing Source Fault Management
Fault management has the capability of switching between the GPS
synchronization source and the HSO/MSO backup source in the event of
a GPS receiver failure. During normal operation, the CSA selects GPS as
the primary timing source (Table 6-20). The source selection can also be
overridden via the WinLMF or by the system software.
Front Panel LEDs
The status of the LEDs on the CSA boards are as follows:
S Steady Green – CSA locked to GPS.
S Rapidly Flashing Green – Standby CSA locked to GPS.
S Flashing Green/Rapidly Flashing Red – CSA 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.

High Stability Oscillator /

(HSO/MSO)
General
CSA and HSO/MSO
The CSA utilizes timing signals provided by either an HSO or MSO to
maintain BTS synchronization during the absence of valid GPS timing
information. WHen a GPS timing signal is available the CSA is
responsible for calibration of the HSO or MSO clock to maximize the
backup timing interval. A minimum period of 24 hours of operation with
a valid GPS reference is required to fully calibrate the HSO backup
reference such that a 24 hour backup interval may be provided.
HSO
The HSO is a free–running backup oscillator that is capable of providing
a minimum backup interval of 24 hours.
MSO
The MSO is a free–running backup oscillator that is capable of providing
a minimum backup interval of 8 hours.
NOTE
6-44
Allow the base site and test equipment to warm up for 60
minutes after any interruption in oscillator power. CSA card
warm-up allows the oscillator oven temperature and oscillator
frequency to stabilize prior to test. Test equipment warm-up
allows the Rubidium standard time base to stabilize in frequency
before any measurements are made.

Test Equipment GPIB Address
Settings
All test equipment is controlled by the WinLMF through an
IEEE–488/GPIB bus. To communicate on the bus, each piece of test
equipment must have a GPIB address set which the WinLMF will
recognize. The standard address settings used by the WinLMF for the
various types of test equipment items are as follows:
S Signal generator address: 1
S Power meter address: 13
S Communications system analyzer: 18
Using the procedures included in the Verifying and Setting GPIB
Addresses section of Appendix B, verify and, if necessary, change the
GPIB address of each piece of employed test equipment to match the
applicable addresses above
Supported Test Equipment
CAUTION
To prevent damage to the test equipment in high power
configurations, all transmit (TX) test connections must be
through a 30 dB directional coupler plus a 20 dB in-line
attenuator for the 800 MHz BTSs.
Attenuators are not required for low power configurations.

Equipment Warm-up
IMPORTANT
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.
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 BBX under test OOS.
Failure to do so can result in serious personal injury
and/or equipment damage.
Automatic Cable Calibration
Set–up
Figure 6-19 and Figure 6-20 show the cable calibration setup for the test
sets supported by the WinLMF. 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 6-24
provides a procedure for performing automatic cable calibration.
Manual Cable Calibration
If manual cable calibration is required, refer to the procedures in
Appendix B.

Test Set Calibration
Background
Proper test equipment calibration helps to ensure accurate BTS
optimization and acceptance testing by assuring that the test equipment
and associated cables do not introduce measurement errors.
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 cables and adapters
actually used to interconnect test equipment items 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 a minimum of 60 minutes.
Calibration Procedures
Included
Automatic
Procedures included in this section use the WinLMF 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 WinLMF computer.

Manual
Agilent E4406A Transmitter Tester – The E4406A does not support
the power level zeroing calibration performed by the WinLMF. If this
instrument is to be used for Bay Level Offset calibration and calibration
is attempted with the WinLMF Calibrate Test Equipment function, the
WinLMF 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 B 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 B .
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 B, if
needed.
GPIB Addresses
GPIB addresses can range from 1 through 30. The WinLMF will accept
any address in that range, but the numbers entered in the WinLMF
Options window GPIB address boxes (Table 6-23 and Table 6-24) must
match the addresses set in 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 B.
Selecting Test Equipment
Serial Connection and Network Connection tabs are provided in the
WinLMF 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 WinLMF 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.
Prerequisites
Be sure the following have been completed before selecting test
equipment:
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 B.

Calibrating Cables Overview
The WinLMF 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. WinLMF cable
calibration consists of the following processes:
1. 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
short cable is deducted from the measured loss of the TX and RX
test cable configurations to determine the actual loss of the
configurations. This deduction is done so any error in the analyzer
measurement will be adjusted out of both the TX and RX
measurements.
2. 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 and, if required by BTS type, an additional
attenuator are also required for the RX test cable configuration.
These additional items must be included in the path loss
measurement.

3. 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 is
different 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.

Setting Cable Loss Values
Cable loss values for TX and RX test cable configurations are normally
set by accomplishing automatic cable calibration using the WinLMF and
the applicable test equipment. The WinLMF 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 6-29 to set cable loss
values.
CAUTION
If cable calibration was performed without using the WinLMF,
cable loss values must be manually entered in the WinLMF
database. Failure to do this will result in inaccurate BTS
calibration and reduced site performance.

Bay Level Offset Calibration
Purpose of Bay Level Offset
Calibration
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.
What is BLO Calibration?
Description
BLO calibration is the complete title of what is normally referred to as
“calibration.” Calibration identifies the accumulated gain in every
transmit path at the BTS site. The transmit path BLO values determined
during calibration are stored in the LMF calibration data file, and are
subsequently downloaded to each BBX. When transmit path calibration
is performed, receive path BLO values will automatically be set to the
default value in the LMF calibration file and downloaded.
Component Verification During
Calibration
TX Path Calibration
TX path calibration supports verification of correct BTS installation, RF
cabling installation and performance, functionality of all equipment
installed in the transmit RF chain, and the proper functioning of each
transmit RF path. External test equipment is used to calibrate and audit
the TX paths of the BTS.
RX Path Calibration
RX path calibration is not required or supported on CDMA BTS
systems. Default RX calibration values are written to the RX calibration
data files during the TX calibration process. RX functionality is verified
during Frame Erasure Rate (FER) testing.
When to Calibrate BLOs
Calibration to determine BLO:
1. Is required after initial BTS installation.
2. Must be done once each year for an operational BTS site.
3. Is recommended by Motorola for all associated RF paths after
replacing any of the following components:
– BBX card
– CCP2 shelf
– cCLPA

BLO Calibration Data File
During the calibration process, the LMF creates a calibration (CAL) data
file where BLO values are stored. After calibration has been completed,
these offset values must be downloaded to the BBXs using the LMF
BLO download function. A detailed description of the file organization
and content is provided in the following paragraphs
NOTE
Due to the size of the file, Motorola recommends printing out a
copy of a bts–#.cal file and referring to it for the following
descriptions.
S When referring to the CAL file print–out it can be seen that there is
one BBX slot with 20 “calibration entries” per BBX (sector) for each
branch. Two calibration entries define a single “calibration point;”
therefore there are ten calibration points in each branch for each BBX.
– The first entry for a calibration point (all odd entries) identifies the
CDMA channel (frequency) where the BLO is measured. The
second calibration entry (all even entries) is the power set level
(PwrLvlAdj) for that frequency. The valid range for PwrLvlAdj is
from 2500 to 27500 (2500 corresponds to –125 dBm and 27500
corresponds to +125 dBm).
– The ten calibration points for each slot–branch combination must be
stored in order of increasing frequency. If less than ten points
(frequencies) are calibrated, the BLO data for the highest frequency
calibrated is written into the remainder of the ten points for that
slot–branch.
Example:
C[1]=384
C[2]=19102
C[3]=777
C[4]=19086
(odd cal entry)
= 1 “calibration point”
(even cal entry)
(odd cal entry)
= 1 “calibration point”
(even cal entry)
C[19]=777
C[20]=19086
(odd cal entry)
(even cal entry)
= 1 “calibration point”
In the example above, BLO was measured at only two frequencies
(channels 384 and 777) for CCP2 slot BBX–1 transmit. The BLO data
for the highest frequency measured (channel 777) will be written to
the remaining eight transmit calibration points (defined by entries
C[5] through C[20]) for BBX–1.
Slot Block Temperature Compensation – Each BBX slot Block also
has a temperature compensation data section (TempLevelCal) where
power level compensation factors for temperature variations are stored.

CAL File and BLO Data Download
When BLO data is downloaded to the BBXs after calibration, the data is
downloaded to the devices in the order it is stored in the CAL file. TX
calibration data (entries C[1] – C[60]) are sent first. Data for the ten
BBX slot 1 calibration points (entries C[1] – C[20]) are sent initially,
followed by data for the ten BBX slot 2 calibration points (entries C[21]
– C[40]), and so on. The RX calibration data is sent next in BBX slot
sequence, followed by RX Diversity calibration data.

If it has not already been done, refer to Table 6-7 (on page 6-25) to start a GUI LMF session.
If not already done, select test equipment per the procedure in Table 6-23 or Table 6-24.
If required, calibrate the test equipment per the procedure in Table 6-25.
! CAUTION
To prevent damage to the test equipment in high power configurations, all transmit (TX) test
connections must be via the 30 dB directional coupler for 800 MHz.
Attenuators are not required for low power configuration.
For TX path calibration, connect the test equipment as shown in Figure 6-14, Figure 6-15, or
Figure 6-16, depending on the communications analyzer being used.

Transmit (TX) Path Calibration
Description
The assigned channel frequency and desired power level at the frame TX
ports for transmit calibration are derived from the BTS CDF file. Each
BBX at the site is assigned to a carrier. These are specified respectively
in the carrier field of the ParentCARRIER parameter in each BBXs CDF
file block. The channel frequency for the assigned sector is specified in
the ChannelList parameter of the CDF block for the CARRIER to
which the BBX is assigned.
For Low Power optimization of the SC480, the following adjustments
must be made to the CDF.
S In the Carrier section of the CDF, verify that the SifPilotPwr is set to
–200.
S In the BTS section of the CDF, verify that the CageConf is set to 5
(CCP2), and that BIOType is set to 3.
NOTE
Be sure the bts–#.cdf and cbsc–#.cdf files loaded on the
LMF computer are current. The LMF will obtain carrier
and channel information from these files and insert it into
the appropriate CDMA Test Parameter screen. Failure to
have the most current files from the CBSC can result in
incorrect channel information being used to calibrate the
BTS and unfavorable affects on BTS performance. Carrier
and channel numbers should only be entered manually for
special test cases or as a last resort.
The calibration process attempts to adjust the measured power to within
+0.5 dB of the desired power. The calibration will pass if the error is less
than +1.5 dB.
Table 6-32 lists the maximum and minimum power with and without the
cCLPA. The numbers presented may change at a later date.

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 Check Box
In both the TX Calibration and All Cal/Audit dialog boxes, a Verify
BLO check box 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 check box should be unchecked or the additional path
losses should be added.
Single–Sided BLO Check Box
An acceptable range of BLO values for each type of BTS is established
to allow for tolerance variations in all the components of the RF chain.
This acceptable range, 42+5 dB for example, is a much wider tolerance
than necessary for the BBXs. Single–Sided BLO calibration restricts the
allowable BLO variations to the lower half of the range (i.e., 37 to 42
dB). Because this is a much more stringent tolerance, calibrations run
with Single–Sided BLO are more likely to fail and should only be
attempted by an experienced CFE.
The Tests > TX > TX Calibration... menu window has a Test Pattern
pull–down menu. This menu has the following choices:
S 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.
S 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.

S 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.
S CDF – This pattern setting is for advanced users who need to use
CDF gain settings for all channels included in the Standard pattern

WARNING
Before installing any test equipment directly to any BTS
TX OUT connector, first verify no CDMA channels are
keyed. Failure to do so can result in serious personal injury
and/or equipment damage.
CAUTION
Always wear an approved anti–static wrist strap while
handling any circuit card or module. If this is not done,
there is a high probability that the card or module could be
damaged by ESD.
NOTE
At new site installations, to facilitate the complete test of
the CCP2 Shelf empty BBX slots may be populated to
ensure 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 (or NECF) 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).

Calibration Audit Introduction
The BLO calibration audit procedure confirms the successful generation
and storage of the BLO calibration values. The calibration audit
procedure measures the path gain or loss of every BBX transmit path at
the site. In this test, actual system tolerances are used to determine the
success or failure of a test. The same external test equipment set–up
required for TX calibration is used for TX audit.
NOTE
RF path verification, BLO calibration, and BLO data
download to BBXs must have been successfully completed
prior to performing the calibration audit.
TX Path Audit
Perform the calibration audit of the TX paths of all equipped BBX slots,
per the steps in Table 6-37.
WARNING
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.
NOTE

Create CAL File
The LMF Create CAL File function gets the BLO data from BBXs and
creates or updates the CAL file for the BTS. After a BTS has been fully
optimized a copy of the CAL file must exist so it can be transferred to
the CBSC. If TX calibration has been successfully performed for all
BBXs and BLO data has been downloaded, the BLO data must be saved
to the CAL file in the BTS folder. If this is a first time calibration and
no CAL file is stored in the BTS folder, the procedure in Table 6-38 will
create the file and store the BLO data in it. If the CAl file already exists,
this procedure will update it with the new BLO data. Note the following:
S The Create Cal File function only applies to selected (highlighted)
BBXs.
CAUTION
Editing the CAL file is not encouraged as this action can
cause interface problems between the BTS and the LMF.
To manually edit the CAL file you must first logout of the

Automated Acceptance Test Procedure – Introduction
Introduction
General
The Acceptance Test Procedures (ATP) allow Cellular Field Engineers
(CFEs) to run automated acceptance tests on all BTS subsystem devices
equipped in the CDF using the LMF and the test equipment it supports.
Test Reports
The CFE can choose to save the results of ATP tests to a report file from
which ATP reports are generated for later printing. See the Generating an
ATP Report section in this chapter.
Test Equipment Selection
Because test equipment functions during acceptance testing are
controlled by the LMF through the GPIB, only the test equipment
models supported by the LMF can be used.
IMPORTANT
1. Before using the LMF, read the Developer Release
Notes section in the LMF Help function on–line
documentation for any applicable information.
2. The ATP test is to be performed on out-of-service
sectors only.
3. DO NOT substitute test equipment with other models
not supported by the LMF.
Test Equipment Set Calibration
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 BTS 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 (minimum recommendation):
1. Verify the TX/RX paths by performing TX Calibration, TX Audit,
and FER tests.
MAY 2004
1X SC480 BTS Hardware Installation, Optimization/ATP, and FRU
PRELIMINARY
7-1
Automated Acceptance Test Procedure – Introduction – continued
2. Retrieve Calibration Data required for normal site operation.
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.
ATP Test Options
ATP tests can be run individually or as one of the following groups:
S All TX: TX tests verify the performance of the BTS transmit
elements. These include the GLI, MCC, BBX, trunking modules, the
LPAs, and passive components including splitters, combiners,
bandpass filter(s), and RF cables.
S All RX: The RX test verifies the performance of the BTS receive
elements. These include the MPC, EMPC (for companion frames),
BBX, MCC, GLI modules, and the passive components including RX
filters and RF cables.
S All TX/RX: Executes all TX and RX tests.
S Full Optimization: Executes the TX calibration, downloads BLO,
and executes the TX audit before running all TX and RX tests.
ATP Prerequisites
Before attempting to run any ATP tests, be sure the following have been
completed:
S BTS has been optimized (BBXs calibrated and BLOs downloaded)
(Chapter 3)
S The carrier(s) and/or sector(s) to be tested have been taken out of

Acceptance Tests – Test Set Up
Required Test Equipment
The following test equipment is required:
LMF
Power meter (used with HP438 and Agilent 8935)
Communications system analyzer
Signal generator for FER testing (required for all communications
system analyzers for 1X FER)
WARNING
Before installing any test equipment directly to any BTS
TX OUT connector, verify that there are no CDMA
channels keyed.
At active sites, have the OMCR/CBSC place the carrier
assigned to the cCLPAs under test OOS. Failure to do so
can result in serious personal injury and/or equipment
damage.
NOTE
The test equipment must be re–calibrated before using it to
perform the TX Acceptance Tests.
Acceptance Test Equipment
Set Up
All ATP testing – Follow the steps in Table 7-1 to set up test equipment
for all tests.
Table 7-1: Set Up Test Equipment – TX Output Verify/Control Tests
Step
Action
If it has not already been done, interface the LMF computer to the BTS (refer to Table 6-6 and
Figure 6-3).
If it has not already been done, refer to Table 6-7 to start a GUI LMF session and log into the BTS.
If it has not already been done, refer to Figure 6-17, Figure 6-18, Figure 6-19, or Figure 6-20,
applicable, for the test equipment and antennas being used, to connect test equipment for acceptance
testing.
* IMPORTANT
LMF–based measurements factor in TX test cable loss between the BTS and test equipment. If
additional attenuation, such as external TX combiners, is inserted in the path, it must be identified to
the LMF by including it in the TX test cable calibration. If this is not possible, include the attenuation
in the TX path by editing cable loss values (refer to Table 6-29). Failure to do this will result in test
inaccuracies and potential for erroneous ATP failures because the additional losses would not be
compensated for in the test measurements.

Abbreviated (All–inclusive) Acceptance Tests
All–inclusive Tests
General – The all–inclusive acceptance tests are performed from the
LMF GUI environment. These all–inclusive tests are called abbreviated
ATPs because they execute various combinations of individual
acceptance tests with a single command. This allows verification of
multiple aspects of BTS performance while minimizing time needed for
individual test set up and initiation.
Abbreviated ATP Options – There are three abbreviated acceptance
tests which evaluate different performance aspects of the BTS. This
allows the CFE to select testing to meet the specific requirements for
individual maintenance and performance verification situations. The
following summarizes the coverage of each abbreviated test:
S All TX/RX. Performs all transmit and receive ATPs on the selected
MCCs and BBXs.
S All TX. Performs complete set of transmit ATPs on the selected
MCCs and BBXs. Testing is the equivalent of performing all of the
following individual tests:
– TX Mask Test
– Rho Test
– Pilot Time Offset Test
– Code Domain Power Test
S All RX. Performs complete receive ATP on the selected MCCs and
BBXs. Testing is the equivalent of performing the following:
– FER Test

Individual Acceptance Tests–Introduction
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
Spectral Purity TX Mask
This test verifies that the transmitted CDMA carrier waveform generated
on each sector meets the transmit spectral mask specification (as defined
in IS–97) 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 IS–97.
Rho represents the correlation between the actual and perfect CDMA
modulation spectrums. 1.0000 represents 100% (or perfect correlation).
Pilot Time Offset
The Pilot Time Offset is the difference between the communications
system test set measurement interval (based on the BTS system time
reference) and the incoming block of transmitted data from the BTS
(Pilot only, Walsh code 0).
Code Domain Power/Noise Floor
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 for IS–95A/B and CDMA2000 1X
with respect to total CDMA channel power.

BTS FER
This test verifies the BTS receive FER on all traffic channel elements
currently configured on all equipped MCCs (fullrate at one percent FER)
at an RF input level of –119 dBm on the main RX antenna paths using
operator–selected, CDF–equipped MCCs and BBXs at the site. Diversity
RX antenna paths are also tested using the lowest equipped MCC
channel element ONLY.
NOTE
There are no pass/fail criteria associated with FER readings
taken at levels below –119 dBm, other than to verify that
the FER measurement reflects changes in the RX input
signal level.

TX Spectral Purity Transmit Mask Acceptance Test
Background
Overview – This test verifies the spectral purity of each
operator–selected BBX carrier keyed up at a specific frequency specified
in the current CDF. All tests are performed using the external, calibrated
test equipment controlled by the same command. All measurements are
made at the appropriate BTS TX antenna connector.
Test Patterns – There are four operator–selectable test patterns with
which this acceptance test can be performed. The patterns, along with the
channels tested and gain setting for each, are listed in Table 6-33. Refer
to “TX Calibration and the LMF” in the Bay Level Offset Calibration
section for more information on the test patterns.
Equipment Operation During Testing – At least one MCC must be
selected to perform the Standard, CDF Pilot, and CDF test patterns. For
these test patterns, forward links will be enabled for synch channel
(SCH), paging channel (PCH), and traffic channel (TCH) elements from
the selected MCC(s), as shown in Table 6-33. Gain will be set for the
applicable channels on each antenna as shown in the table. The
operator–selected BBXs will be keyed using a BLO–corrected bbxlvl
value to generate a CDMA carrier. RF output power, as measured at the
appropriate frame TX antenna connector, will be set to one of the
following depending on the operating frequency spectrum:
S 800 MHz: 33.5 dBm

TX Code Domain Power/Noise Floor Acceptance Test
Background
Overview – This test verifies the Code Domain Power and Noise Floor
of each operator–selected BBX carrier keyed at a specific frequency
specified in the current CDF. All tests are performed using the external,
calibrated test equipment controlled by the same command. All
measurements are made at the appropriate BTS TX antenna connector.
CDMA Channel Test Set–up – Pilot gain will be set to 262 for each
antenna and the selected MCCs will be configured to supply all
odd–numbered Walsh code traffic channel elements by enabling
Orthogonal Channel Noise Source (OCNS) on all odd MCC channel
elements (maximum 32 full rate channels with an OCNS gain of 81). All
even–numbered Walsh code traffic channel elements will not have
OCNS enabled, and are considered “OFF”. Selected MCCs will be
forward–link enabled for the antenna (sector) under test.
Equipment Operation During Testing – The BBX will be keyed up
using a BLO–corrected bbxlvl value to generate a CDMA carrier
consisting of pilot and OCNS channels. RF output power, as measured at
the appropriate frame TX antenna connector, is set at one of the
following values depending on the operating frequency spectrum:
S 800 MHz: 33.5 dBm
Test Measurements – The test equipment will measure and return the
channel element power in dB of all specified Walsh channels within the
CDMA spectrum. Additional calculations will be performed to verify the
following parameters are met (refer to Figure 7-2 for graphic
representations):
S Traffic channel element power level will be verified by calculating the
ratio of Pilot power to OCNS gain of all traffic channels (root sum of
the square (RSS) of each OCNS gain divided by the Pilot power).
This value should be 10.2 dB + 2.0 dB.
S Noise floor (unassigned “OFF” even–numbered Walsh channels) is
verified to be < –27 dB for IS–95A/B and CDMA2000 1X with
respect to total CDMA channel power.

with pilot channel element only. Transmit power output is set at –40
dBm. Test equipment output power is set so that the received power at
the BBX is –119 dBm. The final output power setting of the test
equipment takes into account the MPC type, BTS RF path losses, and
test cable losses. .
Test Measurements – The LMF will prompt the MCC channel element
under test to measure all–zero longcode and provide the FER report on
the selected active MCC on the reverse link for the main and, if selected,
diversity RX antenna paths. Results are evaluated to ensure they meet
the following specification:
FER returned less than 1% and Total Frames measured is 1500
FER Acceptance Test
Follow the steps in Table 7-9 to verify the FER on RX antenna paths
using selected MCCs and BBXs.
Table 7-9: Test FER
Step
Action
Set up the test equipment for RX acceptance tests per Table 7-1.
* IMPORTANT
If the LMF has been logged into the BTS with a different Multi–Channel Preselector setting than the
one to be used for this test, the LMF must be logged out of the BTS and logged in again with the new
Multi–Channel Preselector setting. Using the wrong MPC setting can cause a false test failure.
Select the BBXs and MCCs to be tested.
Click on Tests in the BTS menu bar, and select RX > FER... from the pull–down menu.
Select the appropriate carrier(s) and sector(s) (carrier-bts#-sector#-carrier#) from those displayed in the
Channels/Carrier pick list.

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 8-1 to copy the CAL files from an LMF
computer to a 3.5 diskette.
Table 8-1: Copying CAL Files to a Diskette

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.

Fan Module
Introduction
The fan module is located above the CCP2 Shelf at the front of the
Compact BTS.
The fan mdoule is a modular device allowing easy replacement. The
electrical connection for DC power is made through a connector at the
rear of the module. The connector is automatically engaged when the fan
module is inserted and seated.
System Impact/Considerations
NOTE
At room temperature, the fan module is very quiet.
Operation can be verified by holding a hand over the
exhaust grill on top and feeling for air movement.
IMPORTANT
Performing this replacement procedure will not cause
downtime or interrupt call processing, but it will trigger
alarms.
If a fan begins to degrade or fails, an alarm signal will be sent to the
Clock Synchronization Alarms card in the CCP2 Shelf.
Required Items
Documents
None.
Tools
None.
Replacement Units
For –48 VDC – One fan module (STLN4696)
For +27 VDC – One fan module (STLN6210)
Prerequisite
IMPORTANT
Coordinate this repair task with the OMC–R operator.
Contact the OMC–R operator before performing the replacement
procedure. Tell the operator that the fan module will be replaced and that
alarms can be expected.

High and Medium Stability Oscillator Module
Introduction
The High Stability and Medium Stability Oscillator module provide a
backup reference source in the case of Global Positioning System (GPS)
failure. The HSO is capable of providing up to 24 hours, the
synchronization initially established by the GPS reference signal. The
MSO is capable of providing up to 8 hours.
There is only one HSO or MSO equipped in the Compact BTS. The
module is located in front, behind a cover, underneath the CCP2 Shelf.
The HSO or MSO slides into the top slot of the two that are present.
System Impact/Considerations
The HSO or MSO produces a 1 pulse per second (1 pps) clock output
signal to the CSA.
Front Panel Indicator
The HSO or MSO have no indicators.
