antenna feed line loss can be combined to determine the required
power at the frame antenna connections. The corresponding BBX2
output level required to achieve that power level on any channel/sector
can then be determined based on Bay Level Offset (BLO) data
determined during the optimization process.
Refer to the Figure 3-1 and the LMF Help function for
additional information on the layout of the LMF directory
structure (including CDF file locations and formats).
NOTE
The CDF is normally obtained from the CBSC on a DOS formatted
diskette, or through a file transfer protocol (ftp), if the LMF computer
has ftp capability. Refer to the LMF Help function, and the LMF Help
function, for more information.
CDF Site Equipage Verification
If it has not already been done, review and verify the site equipage data
in the CDF with the actual site hardware and the site engineering
documentation. Use a text editor to view the CDF contents.
Use extreme care not to make any changes to the CDF
content while viewing the file. Changes to the CDF can
cause the site to operate unreliably or render it incapable of
operation.
CAUTION
Always wear a conductive, high impedance wrist strap
while handling any circuit card/module to prevent damage
by ESD. Extreme care should be taken during the removal
and installation of any card/module. After removal, the
card/module should be placed on a conductive surface or
back into the anti–static bag in which it was shipped.
CAUTION
BTS System Release Software
Download
The System Release software (for example R2.15.x.x) being used by the
Base Station System (BSS) must be successfully downloaded to the BTS
processor boards before optimization can be performed. Device
initialization code is normally downloaded to the processor boards from
the CBSC. Device application code and data is loaded from the CDMA
LMF computer terminal.

Overview
Before optimization can be performed, the CDMA LMF must be
installed and configured on a computer platform meeting
Motorola–specified requirements (see Recommended Test Equipment
and Software in Chapter 1).
For the CDMA LMF 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.
IMPORTANT
*
Software and files for installing and updating the CDMA LMF are
provided on CD ROM disks. The following items must be available:
SCDMA LMF Program on CD ROM
SCDMA LMF Binaries on CD ROM
SConfiguration Data File (CDF) for each supported BTS (on floppy
disk)
SCBSC File for each supported BTS (on floppy disk)
The following section provides information and instructions for
installing and updating CDMA LMF software and files.

NOTE
(If applicable, replace the letter d with the correct CD ROM drive letter.)
5Follow the directions displayed in the Setup screen.
Copy CBSC CDF Files to the
LMF Computer
Before logging on to a BTS with the CDMA LMF computer to execute
optimization/ATP procedures, the correct bts-#.cdf and
cbsc-#.cdf files must be obtained from the CBSC and put in a
bts-# folder in the CDMA LMF computer. This requires creating
versions of the CBSC CDF files on a DOS–formatted floppy diskette
and using the diskette to install the CDF files on the CDMA LMF
computer.
When copying CDF files, comply with the following to
prevent BTS login problems with the Windows LMF:
SThe numbers used in the bts-#.cdf and
cbsc-#.cdf filenames must correspond to the
locally–assigned numbers for each BTS and its
controlling CBSC.
SThe generic cbsc–1.cdf file supplied with the Windows
LMF will work with locally numbered BTS CDF files.
Using this file will not provide a valid optimization
unless the generic file is edited to replace default
parameters (e.g., channel numbers) with the operational
parameters used locally.
IMPORTANT
*
The procedure in Table 3-2 lists the steps required to transfer the CDF
files from the CBSC to the CDMA LMF computer. For any further
information, refer to the CDMA LMF Operator’s Guide (Motorola part
no. 68P64114A21) or the CDMA LMF Help screen.

4 Type mount and press the Enter key.
NOTE
SLook for the “floppy/no_name” message on the last line displayed.
SIf 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.
5Change to the directory, where the files to be copied reside, by typing cd <directoryname>
(e.g., cd bts–248) and pressing the Enter key.
6 Type ls and press the Enter key to display the list of files in the directory.
7 With Solaris versions of Unix, create DOS–formatted versions of the bts–#.cdf and cbsc–#.cdf files on
the diskette by entering the following command:
unix2dos <source filename> /floppy/no_name/<target filename>
(e.g., unix2dos bts–248.cdf /floppy/no_name/bts–248.cdf).
NOTE
SOther versions of Unix do not support the unix2dos and dos2unix commands. In these cases, use
the Unix cp (copy) command. The copied files will be difficult to read with a DOS or Windows text
editor because Unix files do not contain line feed characters. Editing copied CDF files on the
CDMA LMF computer is, therefore, not recommended.
SUsing 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).
8Repeat steps 5 through 7 for each bts–# which must be supported by the CDMA LMF computer.
9When all required files have been copied to the diskette type eject and press the Enter key.
10 Remove the diskette from the CBSC drive.
11 If it is not running, start the Windows operating system on the CDMA LMF computer.
12 Insert the diskette containing the bts–#.cdf and cbsc–#.cdf files into the CDMA LMF computer.
13 Using MS Windows Explorer, create a corresponding bts–# folder in the wlmf\cdma directory for each
bts–#.cdf/cbsc–#.cdf file pair copied from the CBSC.
14 Use MS Windows Explorer to transfer the cbsc–#.cdf and bts–#.cdf files from the diskette to the
corresponding wlmf\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 CDMA LMF computer and the FRU. Using features
of the Windows operating system, the connection properties for an MMI
session can be saved on the CDMA LMF computer as a named Windows
HyperTerminal connection. This eliminates the need for setting up
connection parameters each time an MMI session is required to support
optimization.
Once the named connection is saved, a shortcut for it can be created on
the Windows desktop. Double–clicking the shortcut icon will start the
connection without the need to negotiate multiple menu levels.
Follow the procedures in Table 3-3 to establish a named HyperTerminal
connection and create a Windows desktop shortcut for it.

Folder Structure Overview
The CDMA LMF uses a wlmf folder that contains all of the essential
data for installing and maintaining the BTS. The following list outlines
the folder structure for CDMA LMF. Except for the bts-nnn folders,
these folders are created as part of the CDMA LMF installation.

required for each different version; for
example, a folder name 2.8.1.1.1.5.)
loads folder
(C:)
wlmf folder
cdma folder
code folder
data folder
BTS–nnn folders (A separate folder is
required for each BTS where bts–nnn is the
unique BTS number; for example, bts–163.)
wlmf Folder
The wlmf folder contains the CDMA LMF program files.
cdma Folder
The cdma folder contains the bts–nnn folders and the loads folder. It also
contains a default cbsc–1.cdf file that can be copied to a bts–nnn folder
for use, if one cannot be obtained from the CBSC (Centralized Base
Station Controller) when needed.
bts–nnn Folders
Each bts–nnn folder contains a CAL file, a CDF file and a cbsc file for
the BTS. Other files required by CDMA LMF may also be located in the
bts–nnn folder. A bts–nnn folder must be created for each BTS that is to
be logged in to. The bts–nnn folder must be correctly named (for
example: bts–273) and must be placed in the cdma folder. Figure 3-2
shows an example of the file naming syntax for a BTS folder.

cbsc File
The cbsc–#.cdf (Centralized Base Station Controller) file contains data
for the BTS. If one is not obtained from the CBSC, a copy of the default
cbsc–1.cdf file located in the cdma folder can be used.
Using the generic cbsc–1.cdf file will not provide a valid
optimization unless the generic file is edited to replace
default parameters with local operational parameters (e.g.,
CDMA channel numbers must be changed from the default
“384” to those used locally by the BTS).
IMPORTANT
*
loads Folder
The loads folder contains the version folder(s). It does not contain any
files.
version Folder
The version folder(s) contains the code and data folders. It does not
contain any files. The name of version folders is the software version
number of the code files that are included in its code folder. Version
folders are created as part of the CDMA LMF installation and CDMA
LMF updates. Each time the CDMA LMF is updated, another version
folder will be created with the number of the software version for the
code files being installed.
code Folder
The code folder contains the binary files used to load code into the
devices. A unique binary code file is required for each device type in the
BTS to be supported with the CDMA LMF. Current version code files
for each supported device created in this folder from the CDMA LMF
CD ROM as part of the CDMA LMF installation/update process.
Figure 3-5 shows an example of the file naming syntax for a code load
file.

1X SCt4812ET Lite BTS Optimization/ATP 08/01/2001
3-14
T1/E1 Span Interface
At active sites, the OMC–R/CBSC must disable the BTS
and place it out of service (OOS). DO NOT remove the
span line cable conectors until the OMC–R/CBSC has
disabled the BTS.
IMPORTANT
*
Each frame is equipped with one 50–pair punchblock for spans,
customer alarms, remote GPS, and BTS frame alarms. See Figure 3-9
and refer to Table 3-5 for the physical location and punchdown location
information.
Before connecting the LMF computer to the frame LAN, the
OMC–R/CBSC must disable the BTS and place it OOS to allow the
LMF to control the BTS. This prevents the CBSC from inadvertently
sending control information to the BTS during LMF–based tests.
Isolate BTS from T1/E1 Spans
Once the OMC–R/CBSC has disabled the BTS, the spans must be
disabled to ensure the LMF will maintain control of the BTS. To disable
the spans, disconnect the cable connector for the BTS–to–CBSC
Transcoder span at the Span I/O card (Figure 3-7).
If the BTS is a multi–frame logical BTS, do not disconnect
the inter–frame span.

Configure Optional Channel
Service Units
The M–PATH 537 Channel Service Unit (CSU) module provides
in–band SNMP–managed digital service access to T1 and fractional T1
lines. The M–PATH 437 Channel Service Unit (CSU) module provides
in–band SNMP–managed digital service access to E1 and fractional E1
lines. CSU modules units plug into the CSU shelf (see Figure 3-8).
The CSU shelf can support two M–PATH 537 or two M–PATH 437 CSU
modules. The 537 CSU module supports a single T1 span connection.
The 437 CSU module supports a single E1 span connection.
Remote M–PAT H management is available via SNMP over an in–band
data link on the span line (using a facility data link or 8–64 Kbps of a
DS0 channel). The unit at the near end of the management path can be
an SNMP manager or another M–PATH CSU.
Programming of the M–PATH is accomplished through the DCE 9–pin
connector on the front panel of the CSU shelf. Manuals and a Microsoft
Windows programming disk are supplied with each unit.
For more information refer to M–PATH T1 Channel Service Unit User’s
Guide, ADC Kentrox part number 65–77538101 or the M–PATH E1
Channel Service Unit User’s Guide, ADC Kentrox part number TBD.
Setting the Control Port
Whichever control port is chosen, it must first be configured so the
control port switch settings match the communication parameters being
used by the control device. If using the rear–panel DTE control port, set
the SHELF ADDRESS switch SA5 to “up.” If using the rear–panel DCE
control port, position the SHELF ADDRESS switch down.
For more information, refer to the 2–Slot Universal Shelf Installation
Guide, ADC Kentrox part number 65–78070001.

PRELIMINARY
Basic CDMA LMF Operation
The CDMA LMF allows the user to work in the two following operating
environments which are accessed using the specified desktop icons:
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 CDMA LMF in either environment includes
performing the following:
SSelecting and Deselecting BTS devices
SEnabling devices
SDisabling devices
SResetting devices
SObtaining device status
The following additional basic operation can be performed in a GUI
environment:
SSorting a status report window
For detailed information on performing these and other CDMA LMF
operations, refer to the LMF Help function and the LMF CLI Reference;
68P09253A56.
Unless otherwise noted, LMF procedures in this manual
are performed using the GUI environment.
IMPORTANT
*
CDMA LMF and Logical BTS
An SC4812ET Lite logical BTS can consist of up to two SC4812ET Lite
frames. When the CDMA LMF is connected to a frame 1 Ethernet port
of a logical BTS, access is available to all devices in all of the frames
that make up the logical BTS. A logical BTS CDF file that includes
equipage information for all of the logical BTS frames and their devices
is required for proper LMF interface. A CBSC CDF file that includes
channel data for all of the logical BTS frames is also required.
The first frame of a logical BTS has a –1 suffix (for example,
BTS–812–1) and the second frame of the logical BTS is numbered with
the suffix, –101 (e. g. BTS–812–101). When the CDMA LMF is logged
into a BTS, a FRAME tab is displayed for each frame. If there is only
one frame for the BTS, there will only be one tab (e.g., FRAME–282–1
for BTS–282). If a logical BTS has more than one frame, there will be a
3

separate FRAME tab for each frame(for example, FRAME–438–1, and
FRAME–438–101 for BTS–438 that has both frames). If an RFDS is
included in the CDF file, an RFDS tab (e.g., RFDS–438–1) will be
displayed.
Actions, such as ATP tests, can be initiated for selected devices in one or
more frames of a logical BTS. Refer to the CDMA LMF Select devices
help screen for information on how to select devices.
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 invalid optimization.
Failure to use the correct CDF files to log into a live
(traffic–carrying) site can shut down the site.
CAUTION
Logging into a BTS establishes a communications link between the BTS
and the CDMA LMF. You may be logged into one or more BTSs at a
time, but only one CDMA LMF may be logged into each BTS.
Before attempting to start the CDMA LMF computer and the CDMA
LMF software, confirm the CDMA LMF computer is properly connected
to the BTS (see Table 3-6). Follow the procedures in Table 3-7 to log
into a BTS.
Prerequisites
Before attempting to log into a BTS, ensure the following have been
completed:
SThe CDMA LMF is correctly installed and prepared.
SA bts-nnn folder with the correct CDF and CBSC files exists.
SThe CDMA LMF computer was connected to the BTS before starting
the Windows operating system and the CDMA LMF software. If
necessary, restart the computer after connecting it to the BTS in
accordance with Table 3-6 and Figure 3-10.

Overview
Before a BTS can operate, each equipped device must contain device
initialization (ROM) code. ROM code is loaded in all devices during
manufacture or factory repair. 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 CDMA 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 in the
device does not match the 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 Release 9.2
software where a GLI loaded with Release 2.8.1 ROM code must be
installed to replace a malfunctioning MGLI.
Before ROM code can be downloaded from the CDMA 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. The same Revision–level RAM code must then
be downloaded to the device. For example, if Release 2.9.2.1.1 ROM
code is downloaded, Release 2.9.2.1.1 RAM code must be downloaded.
Procedures to load ROM code are located in Appendix G.
RAM Code
Before RAM code can be downloaded from the CDMA 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 CDMA LMF file structure. The RAM code file will be selected
automatically if the file is in the \lmf\cdma\loads\n.n.n.n\code folder
(where n.n.n.n is the version number of the download code that matches
the “NextLoad” parameter of the CDF file). The RAM code file in the
code folder must have the correct hardware bin number.
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). When code is downloaded to an MGLI
or GLI, the CDMA LMF automatically also downloads data and then
enables the MGLI. When enabled, the MGLI will change to INS (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).

RAM code downloading requires a few minutes. After the download
starts, the non–GLI device being loaded changes to OOS–ROM (blue). If
the download is completed successfully, the non–GLI device changes to
OOS–RAM (yellow).
The devices to be loaded with RAM code and data are:
SMaster Group Line Interface (MGLI2)
SRedundant GLI (GLI2)
SClock Syncronization Module (CSM) (Only if new revision code must
be loaded)
SMulti Channel CDMA (MCC24 or MCC8E) card
SBroadband Transceiver (BBX2)
SRFDS Test Subscriber Interface Card (TSIC), if equipped
The MGLI must be successfully downloaded with RAM
code and data, and in INS (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 RAM code which is for a different
system release than the ROM code with which they are loaded. Before
downloading RAM code and data to the processor cards, follow the
procedure in Table 3-13 to verify the GLI devices are loaded with the
correct ROM code for the system release used by the BSS.
Table 3-13: 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 3-7).
2Select all GLI devices by clicking on them, and select Device > Status from the menu bar.
3In the status report window which opens, note the number in the ROM Ver column for each GLI2.
SThe system release number will be the first two decimal divisions of the number; for example, the
number 2.15.0.0.3 would be for System Release 2.15, and 2.9.2.2.34 would be for System Release
2.9.
4If the ROM code loaded in the GLIs is not for the correct system release, log out of the BTS,
disconnect the CDMA LMF computer, reconnect the span lines as described in Table 5-7, and have the
CBSC download the correct ROM code version to the BTS devices.
5When the GLIs have the correct ROM load for the system release being used, be sure the span lines
are disabled as outlined in Table 3-4 and proceed to downloading RAM code and data.

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
on–board GPS module (RF–GPS) or a remote GPS receiver (R–GPS).
The GPS receiver interfaced to CSM 1 is used as the primary timing
reference and synchronizes the entire cellular system. CSM 2 provides
clock syncronization back–up, but does not have a GPS receiver.
The BTS may be equipped with a LORAN–C Low Frequency Receiver
(LFR), a High Stability Oscillator (HSO), or external 10 MHz Rubidium
source which the CSM can use as a secondary timing reference. In all
cases, the CSM monitors and determines what reference to use at a given
time.
For RF–GPS, verify the CSM configured with the GPS
receiver “daughter board” is installed in the frame’s CSM 1
slot before continuing.

Step Action
* 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 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).
3NOTE
SIf equipped with two CSMs, CSM–1 should be bright green (INS–ACT) and CSM–2 should be
dark green(INS–STB)
SIf more than an hour has passed, refer to CSM Verification, see Figure 3-13 and Table 3-20 to
determine the cause.
After the CSMs have been successfully enabled, be sure the PWR/ALM LEDs are steady green
(alternating green/red indicates the card is in an alarm state).
Enable MCCs
This procedure configures the MCC and sets the “tx fine adjust”
parameter. The “tx fine adjust” parameter is not a transmit gain setting,
but a timing adjustment that compensates for the processing delay in the
BTS (approximately 3 mS).
Follow the steps outlined in Table 3-18 to enable the MCCs installed in
the SCCP shelves.
The MGLI and CSM must be downloaded and enabled,
prior to downloading and enabling the MCC.

PRELIMINARY
Clock Synchronization
Manager (CSM) System Time
The primary function of the Clock Synchronization Manager (CSM)
cards is to maintain CDMA system time. The CSM card in SCCP shelf
slot CSM–1 is the primary timing source while the card in slot CSM–2
provides redundancy. The second generation CSM card (CSM2) 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. A CSM2 card can have a local GPS receiver daughter card to
support an RF–GPS signal.
Each CSM2 card features a temperature–stablized, crystal oscillator that
provides 19.6608 MHz clock, even second pulse, and 3 MHz reference
signals to the synchronization source selected from the following (refer
to Table 3-20 for source selection/verification procedures):
SGPS: local/RF–GPS or remote/R–GPS
SLORAN–C Low Frequency Receiver (LFR) or High Stability
Oscillator (HSO)
SExternal reference oscillator sources
CDMA Clock Distribution Cards (CCDs) buffer and distribute
even–second reference and 19.6608 MHz clock signals from the CSM
cards. CCD 1 is married to the card in slot CSM–1, and CCD 2 is
married to the card in slot CSM–2.
The BTS switches between the primary and redundant units (card slots
CSM–1 and CSM–2, respectively) upon failure or command. A failure
in CSM–1 or CCD 1 will cause the system to switch to the
CSM–2–CCD 2 redundant card pair.
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 in CSM–1. During normal operation, the card in
CSM–1 selects GPS as the primary timing source (Table 3-20). The
source selection can also be overridden via the CDMA LMF or by the
system software.
In addition to providing GPS synchronization to the LFR or HSO
back–up sources, synchronization between the primary and redundant
CSM–CCD pairs increases reliability.
Low Frequency Receiver/
High Stability Oscillator
The CSM performs 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–C RF
signals. Timing pulses are derived from this signal, which is
3
CSM System Time – GPS & LFR/HSO Verification – continued
PRELIMINARY
1X SCt4812ET Lite BTS Optimization/ATP 08/01/2001
3-38
synchronized to Universal Time Coordinates (UTC) and GPS time. The
LFR can maintain system time indefinately after initial GPS lock.
The HSO is a high stability 10 MHz oscillator with the necessary
interface to the CSMs. The HSO is typically installed in those
geographical areas not covered by the LORAN–C system. Since the
HSO is a free–standing oscillator, system time can only be maintained
for 24 hours after 24 hours of GPS lock.
Upgrades and Expansions: LFR2/HSO2/HSOX
LFR2/HSO2 (second generation cards) both export a timing signal to the
expansion or logical BTS frames. The associated expansion or logical
frames require an HSO–expansion (HSOX) whether the starter frame has
an LFR2 or an HSO2. The HSOX accepts input from the starter frame
and interfaces with the CSM cards in the expansion frame. LFR and
LFR2 use the same source code in source selection (Table 3-20). HSO,
HSO2, and HSOX use the same source code in source selection
(Table 3-20).
Allow the base site and test equipment to warm up for
60 minutes after any interruption in oscillator power. CSM
card 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.

Equipment Warm-up
Warm-up BTS equipment for a minimum of 60 minutes
prior to performing the BTS optimization procedure. This
assures BTS site stability and contributes to optimization
accuracy. (Time spent running initial 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 BBX
channels keyed. At active sites, have the OMC-R/CBSC
place the antenna (sector) assigned to the LPA under test
OOS. Failure to do so can result in serious personal injury
and/or equipment damage.

Test Set Calibration
PRELIMINARY
08/01/2001 3-55
1X SCt4812ET Lite BTS Optimization/ATP
Background
Proper test equipment set–up ensures that all measurements are correct
and the test equipment and associated test cables do not introduce
measurement errors.
If the test equipment set (see Chapter 1, Terms and
Abbreviations) being used to interface with the BTS has
been calibrated and maintained as a set, this procedure does
not need to be performed.
NOTE
This procedure must be performed before 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, 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.
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 equipment set. After
calibration, the gain/loss offset values are stored in a test measurement
offset file on the CDMA LMF.

Selecting Test Equipment
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.
STest equipment GPIB addresses have been verified as correct.
SCDMA LMF computer serial port and test equipment are connected to
the GPIB box.
Selecting Test Equipment

4Click on OK to close the status report window.
Calibrating Cables – Overview
The cable calibration function is used to measure the loss (in dB) for the
TX and RX cables that are to be used for testing. A CDMA analyzer is
used to measure the loss of each cable configuration (TX cable
configuration and RX cable configuration). The cable calibration
consists of the following steps.
SMeasure the loss of a short cable. This is done to compensate for any
measurement error of the analyzer. The 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.
SThe short cable plus the RX cable configuration loss is measured. The
RX cable configuration normally consists only of a coax cable with
type–N connectors that is long enough to reach from the BTS RX port
the test equipment. For BTSs with antenna ports carrying duplexed TX
and RX, a directional coupler and, if required by BTS type, an
additional attenuator are also used on the RX cable configuration and
must be included in the measurement.
SThe short cable plus the TX cable configuration loss is measured. The
TX cable configuration normally consists of two coax cables with
type–N connectors and a directional coupler, a load, and an additional
attenuator if required by the BTS type. The total loss of the path loss
3

PRELIMINARY
08/01/2001 3-59
1X SCt4812ET Lite BTS Optimization/ATP
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.
Calibrating Cables with a
CDMA Analyzer
The Cable Calibration menu item from the Util menu list is used to
calibrate both TX and RX test cables for use with CDMA LMF.
LMF cable calibration cannot be accomplished with an
HP8921A analyzer for 1.9 MHz. A different analyzer type
or the signal generator and spectrum analyzer method must
be used (refer to Table 3-27 and Table 3-28). Cable
calibration values must be manually entered if the signal
generator and spectrum analyzer method is used. For the
HP8921A, refer to Appendix F.
NOTE
The test equipment must be selected before this procedure can be started.
Follow the procedure in Table 3-26 to calibrate the cables. Figure 3-14
illustrates the cable calibration test equipment setup.
Table 3-26: Cable Calibration
Step Action
1From the Util menu, select Cable Calibration. A Cable Calibration window is displayed.
2Enter a channel number(s) in the Channels box. Multiple channels numbers must be separated with a
comma, no space (i.e., 200,800). When two or more channels numbers are entered, the cables will be
calibrated for each channel. Interpolation will be accomplished for other channels as required for TX
calibration.
3 Select TX and RX CABLE CAL, TX CABLE CAL or RX CABLE CAL in the Cable Calibration
picklist.
4 Click OK. Follow the directions displayed for each step. A status report window will be displayed
with the results of the cable calibration.

3Use spectrum analyzer to measure signal generator output (see Figure 3-19, “A”) and record the value.
4Connect the spectrum analyzer’s short cable to point “B”, as shown in the lower portion of the
diagram, to measure cable output at customer frequency (869.7–893.31 MHz band for North American
cellular and 1930–1990 MHz for North American PCS) and record the value at point “B”.
5Calibration factor = A – B Example: Cal = –1 dBm – (–53.5 dBm) = 52.5 dB
NOTE
The short cable is used for calibration only. It is not part of the final test setup. After calibration is
completed, do not re-arrange any cables. Use the equipment setup, as is, to ensure test procedures use
the correct calibration factor.

Introduction
Calibration compensates for normal equipment variations within the
BTS and assures maximum measurement accuracy.
RF Path Bay Level Offset
Calibration
Bay Level Offset (BLO) calibration identifies the accumulated gain in
every transmit path (BBX2 slot) at the BTS site and stores that value in
the CDMA LMF CAL file. The BLOs are subsequently downloaded to
each BBX2.
Each transmit path starts at an SCCP shelf backplane BBX2 slot, travels
through the CIO card, trunking module, LPA, trunking module (again),
TX filter or TX filter combiner, DRDC or TRDC, and ends at a BTS TX
antenna port.
Each receive path starts at a BTS RX antenna port, travels through a
DRDC or TRDC, the MPC card, the CIO card, and terminates at a
backplane BBX2 slot.
Calibration identifies the accumulated gain in every transmit path ( by
BBX2 slot) at the BTS site and stores that value in the CAL file. 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:
SBBX2 board
SSCCP shelf
SCIO card
SCIO–to–LPA trunking module RF cable
SLPA trunking module
SLPA
STrunking module–to–TX filter/filter combiner RF cable
STX filter or TX filter combiner
STX filter/filter combiner–to–DRDC/TRDC cable

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 SCCP shelf (if the shelf is not already fully populated
with BBX2 boards), move BBX2 boards from shelves
currently not under test and install them into the empty
BBX2 slots of the shelf currently being tested to insure that
all BBX2 TX paths are tested.
–This procedure can be bypassed on operational sites
that are due for periodic optimization.
–Prior to testing, view the CDF file to verify the
correct BBX2 slots are equipped. Edit the file as
required to include BBX2 slots not currently
equipped (per Systems Engineering documentation).
IMPORTANT
*
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 routine. Functionality is verified
during Frame Erasure Rate (FER) testing.

BLO Calibration Data File
During the calibration process, the CDMA LMF creates a calibration
(CAL) data file where BLO values are stored. After calibration has been
completed, this offset data must be downloaded to the BBX2s using the
CDMA LMF Download BLO function. An explanation of the file is
shown below.
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.
NOTE
The CAL file is subdivided into sections organized on a per–slot basis (a
slot Block).
The Slot 1 Block contains the calibration data for the six BBX2 slots.
The Slot 20 Block contains the calibration data for the redundant BBX2
(see Table 3-32). Each BBX2 slot Block header 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 – plus the slot Block format.
Within the slot Block body, the BBX2 calibration data (BayLevelCal) is
organized as a large flat array. The array is organized by branch, BBX2
SCCP cage slot, and calibration point.
SThe 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:

SRefer to the CAL file print–out and Table 3-32. It can be seen that
there is one BBX2 slot per sector, and 10 calibration points for each
BBX2 (sector) are supported for each branch. Each “calibration point”
consists of two entries.
SThe first entry for a calibration point (all odd entries) identifies the
CDMA channel (frequency) where the BLO is measured. The second
calibration point entry (all even entries) is the power set level
(PwrLvlAdj). The valid range for PwrLvlAdj is from 2500 to 27500

(2500 corresponds to –125 dBm and 27500 corresponds to +125
dBm).
SThe 10 calibration points for each slot/branch combination must be
stored in order of increasing frequency. If less than 10 points
(frequencies) are calibrated, the BLO data for the highest frequency
calibrated is written into the remainder of the 10 points for that
slot/branch.
Example:
C[1]=384 (odd cal entry)
C[2]=19102 (even cal entry)
C[3]=777 (odd cal entry)
C[4]=19086 (even cal entry)
C[19]=777 (odd cal entry)
C[20]=19086 (even cal entry)
.
.
.
= 1 “calibration point”
In the example above, BLO was measured at only two frequencies
(channels 384 and 777) for SCCP slot BBX–1 transmit (Table 3-32).
The BLO data for the highest frequency measured (777) will be
written to the remaining eight transmit calibration points (defined by
entries C[5] through C[20]) for BBX2–1.
SWhen BLO data is downloaded to the BBXs, the data is downloaded
to the devices in the order it is stored in the CAL file. TxCal data
(C[1] – C[60]) is sent first. BBX2 slot 1’s 10 calibration points (C[1]
– C[20]) are sent initially, followed by BBX2 slot 2’s 10 calibration
points (C[21] – C[40]), and so on. The RxCal data is sent next,
followed by the RxDCal data.
STemperature compensation data (TempLevelCal) is also stored in the
CAL file for each slot Block.

! 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.
4For TX path calibration, verify that the coaxial cable from the appropriate ANTENNA connector
(Figure 1-6 or Figure 1-7) is connected to the test equipment RF input port via the directional
coupler.
Transmit (TX) Path Calibration
The assigned channel frequency and desired power level at the frame TX
ports for transmit calibration are derived from the BTS CDF file. Each
BBX2 at the site is assigned to a sector and carrier. These are specified
respectively in the sector and carrier fields of the ParentCARRIER
parameter in each BBX2’s CDF file block. The channel frequency and
desired power for the assigned sector are specified respectively in the
ChannelList and SIFPilotPwr parameters of the CDF block for the
CARRIER to which the BBX2 is assigned.
The calibration procedure 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.
The TX BLO for the SC4812ET Lite is approximately 42.0 dB ±5.0 dB.
BLO is the gain in dB between the known power output of the BBX2
and the measured power at the TX port. BLO is derived by deducting the
known BBX2 power output from the power measured at the TX port or
(Measured Power) – (BBX2 TX Power Output).
Example:
Measured Power (at TX port) = 36.0 dBm
Known BBX TX Power Output = –6.0 dBm
BLO = (36.0) – (–6.0) = 42.0 dB gain
The CDMA LMF Tests menu list items TX Calibration and All
Cal/Audit perform TX BLO Calibration testing for installed BBX(s).
The All Cal/Audit menu item initiates a series of actions to perform TX
calibration, download BLO, and perform TX audit if the TX calibration
passes. The TX Calibration selection performs only the TX calibration.
When the TX Calibration selection is used, BLO download and TX
audit must be performed as separate activities. All measurements are
made through the appropriate antenna connector using the calibrated TX
cable setup.
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.

RFDS TSU NAM Programming
The NAM (number assignment module) information needs to be
programmed into the TSU before it can receive and process test calls, or
be used for any type of RFDS test. The RFDS TSU NAM must be
programmed with the appropriate system parameters and phone number
during hardware installation. The TSU phone and TSU MSI must be
recorded for each BTS used for OMC–R RFDS software configuration.
The user will only need to program the NAM for the initial
install of the RFDS.

RFDS Calibration
The RFDS Calibration option is used to calibrate the RFDS TX and RX
paths. For a TX antenna path calibration the BTS XCVR is keyed at a
pre–determined power level and the BTS power output level is measured
by the RFDS. The power level is then measured at the TX antenna
directional coupler by the power measuring test equipment item being
used (power meter or analyzer). The difference (offset) between the
power level at the RFDS and the power level at the TX antenna
directional coupler is used as the TX RFDS calibration offset value.
For an RX antenna path calibration the RFDS is keyed at a
pre–determined power level and the power input level is measured by the
BTS XCVR. A CDMA signal at the same power level measured by the
BTS XCVR is then injected at the RX antenna directional coupler by the
CDMA communications analyzer. The difference (offset) between the
RFDS keyed power level and power level measured at the BTS XCVR is
the RFDS RX calibration offset value.
The TX and RX RFDS calibration offset values are written to the CAL
file.
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 3-44.
Table 3-44: 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 BBX
channels keyed. Failure to do so can result in serious
personal injury and/or equipment damage.

Automated Acceptance Test Procedure – Introduction
08/01/2001 4-1
1X SCt4812ET Lite BTS Optimization/ATP
PRELIMINARY
Introduction
The automated Acceptance Test Procedure (ATP) allows Cellular Field
Engineers (CFEs) to run automated acceptance tests on all equipped BTS
subsystem devices using the CDMA LMF GUI environment and
supported test equipment.
The operator can choose to save the results of these tests to a report file,
from which ATP reports are generated for later printout.
Perform the ATP test on out-of-service sectors or sites only. Because all
tests are controlled via the CDMA LMF computer using the GPIB
interface from the CDMA LMF computer, only recommended test
equipment supported by the CDMA LMF can be used.
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.
IMPORTANT
*
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.
IMPORTANT
*
Refer to Chapter 3 for detailed information on test set
connections for calibrating equipment, cables and other test
set components, if required.
NOTE
The CFE selects the appropriate ATP tests to run to satisfy customer and
regulatory requirements for verifying cell site performance. These tests
can be run individually or as one of the following groups:
SAll TX: TX tests verify the performance of the BTS transmit
elements. These include the GLI2, MCC, BBX2, BDC, and trunking
modules, the LPAs, and passive components including splitters,
combiners, bandpass filter(s), and RF cables.
SAll RX: RX tests verify the performance of the BTS receive elements.
These include the MPC (for starter frames), , BBX2, MCC, and GLI2
modules, and the passive components including RX filter (starter
frame only), and RF cables.
SAll TX/RX: Executes all TX and RX tests.
SFull Optimization: Executes the TX calibration, downloads BLO,
and executes the TX audit before running all TX and RX tests.

Prerequisites
Before attempting to run any ATP tests, all applicable procedures
outlined in Chapter 3, Optimization/Calibration, must have been
completed successfully (i.e., code load and BLO calibration).
You cannot substitute test equipment with other models not
supported by the CDMA LMF.
NOTE
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, BBX2s, 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
SBBX2s are OOS-RAM
SBBX2s 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
connectors are properly terminated.
All transmit connectors must be properly terminated for all
ATP tests.
Failure to observe these warnings may result in bodily
injury or equipment damage.
WARNING
TX/RX Antenna Connections
Refer to Figure 1-6 or Figure 1-7 for identification of the transmit and
receive antenna connections where measurement are to be taken.
Directional couplers for signal sampling by the RFDS, if installed, are
integral to the SC4812ET Lite transmit and receive paths in the DRDCs
and TRDCs. As a result, all ATP measurement connections are made at
the antenna connectors on the RF interface panel.

Required Test Equipment
The following test equipment is required:
SLMF
SPower meter (used with HP8921A/600 and Advantest R3465)
SCommunications test set
Before installing any test equipment directly to any TX
OUT connector, verify that there are no CDMA channels
keyed.
At active sites, have the OMCR/CBSC place the carrier
assigned to the LPAs under test OOS. Failure to do so can
result in serious personal injury and/or equipment damage.
WARNING
You must recalibrate the test equipment before using it to
perform the TX Acceptance Tests.
NOTE
Acceptance Test Equipment
Set Up
Follow the steps in Table 4-1 to set up test equipment for all tests.
Table 4-1: Set Up Test Equipment – TX Output Verify/Control Tests
Step Action
1If it has not already been done, interface the LMF computer to the BTS (refer to Table 3-6 and
Figure 3-10).
2If it has not already been done, refer to Table 3-7 to start a GUI LMF session and log into the BTS.
3If it has not already been done, refer to Figure 3-17 or Figure 3-18, as applicable for the test
equipment being used, to connect test equipment for acceptance testing.

All–inclusive Tests
The all–inclusive acceptance tests are performed from the LMF GUI
environment. These tests 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.
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:
SAll TX/RX. Performs all transmit and receive ATPs on the selected
MCCs and BBX2s.
SAll TX. Performs complete set of transmit ATPs on the selected
MCCs and BBX2s. Testing is the equivalent of performing all of the
following individual tests:
–TX Mask Test

Individual Acceptance Tests–Introduction
08/01/2001 4-7
1X SCt4812ET Lite BTS Optimization/ATP
PRELIMINARY
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 CDMA 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 set. All
measurements are via the appropriate TX OUT connector.
TX tests verify TX operation of the entire CDMA Forward Link using
all BBX2s assigned to all respective sector/antennas. Each BBX2 is
keyed up to generate a CDMA carrier (using both bbx level and bay
level offsets) at the CDF file carrier output power level (as specified in
the site documentation).
RX Testing
RX testing verifies any given receive antenna path. All tests are
performed using the external calibrated test set to inject a CDMA RF
carrier with all zero longcode at the specified RX frequency via the
appropriate RX IN connector.
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 CDMA analyzer
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 (with respect to total CDMA channel
power).
BTS Frame Error Rate
This test verifies the BTS receive Frame Error Rate (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 all equipped MCCs and BBX2s at the site. The
diversity RX antenna paths are also tested using the lowest equipped
MCC/CE ONLY.
There are no pass/fail criteria associated with FER readings
taken at level below –119 dBm, other than to verify that
the FER measurement reflects changes in the RX input
signal level.

1X SCt4812ET Lite BTS Optimization/ATP
PRELIMINARY
Background
This test verifies the Code Domain Power and Noise Floor of each BBX
carrier keyed up at a specific frequency per the current CDF file
assignment. All tests are performed using the external calibrated test set
controlled by the same command. All measurements are via the
appropriate TX OUT connector.
Pilot gain will be set to 262 for each antenna and all equipped MCCs
will be configured to supply all odd–numbered Walsh code Traffic
channel elements by enabling Orthagonal Channel Noise Source
(OCNS) on all odd MCC/CEs, (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”. All
equipped MCCs will be forward–link enabled for the antenna/sector
under test.
The BBX2 will be keyed up using both bbxlvl and bay level offsets, to
generate a CDMA carrier consisting of pilot and OCNS channels. RF
output power is set at 40 dBm as measured at the appropriate TX output.
The calibrated communications test set will measure and return the
channel element power (dB) of all specified Walsh channels within the
CDMA spectrum. Additional calculations will be performed to verify the
following parameters are met (Figure 4-2):
STraffic 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.
SNoise floor (unassigned “OFF” even numbered Walsh channels) are
verified to be < –27 dB (with respect to total CDMA channel power).
The BBX2 will then dekey, and if selected, the redundant BBX2 will be
assigned to the current TX antenna path under test. The test will then be
repeated. Upon completion of the test, OCNS channels will be disabled
on the specified MCC/CEs.

Updating CBSC Calibration
Data Files
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 Disk
Follow the procedures in Table 5-1 to copy the CAL files from a CDMA
LMF computer to a 3.5 diskette.
Table 5-1: Copying CAL Files to a Diskette
Step Action
1With Windows running on the CDMA LMF computer, insert a disk into Drive A:.
2Launch the Windows Explorer Program from your Programs menu list.
3Select the applicable wlmf/cdma/bts–# folder.
4Drag the bts–#.cal file to Drive A.
5Repeat Steps 3 and 4, as required, for other bts–# folders.
Copying CAL Files from Diskette to the CBSC
Follow the procedures in Table 5-2 to copy CAL files from a diskette to
the CBSC.
Table 5-2: Copying CAL Files from Diskette to the CBSC
Step Action
1Log in to the CBSC on the OMC–R Unix workstation using your account name and password.
2Place your diskette containing calibration file(s) in the workstation diskette drive.
3Type in eject –q and press the Enter key.
4Type in mount and press the Enter key.
NOTE
SCheck to see that the message “floppy/no_name” is displayed on the last line.
SIf the eject command was previously entered, floppy/no_name will be appended with a number.
Use the explicit floppy/no_name reference displayed.
5Type in cd /floppy/no_name and press the Enter key.
6Type in ls –lia and press the Enter key. Verify that the bts–#.cal file is on the diskette.
7Type in cd and press the Enter key.
8Type in pwd and press the Enter key. Verify you are in your home directory (/home/<name>).

Table 5-2: Copying CAL Files from Diskette to the CBSC
Step Action
9 With Solaris versions of Unix, create a Unix–formatted version of the bts–#.cal file in your home
directory by entering the following command:
dos2unix /floppy/no_name/bts–#.cal bts–#.cal and press the Enter key (where # is BTS
number).
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.
11 Type in eject and press the Enter key.
12 Remove the diskette from the workstation.

Removing External Test
Equipment Perform the procedure in Table 5-3 to disconnect the test equipment and
configure the BTS for active service.
Table 5-3: Remove External Test Equipment
Step Action
1Disconnect all external test equipment from all TX and RX connectors at the rear of the frame.
2Reconnect and visually inspect all TX and RX antenna feed lines at the frame RF interface panel.
! CAUTION
Verify that all sector antenna feed lines are connected to the correct ports on the frame. Crossed
antenna cables will cause system degradation of call processing.
Reset All Devices and Initialize
Site Remotely
Generally, devices in the BTS should not be left with data and code
loaded from the CDMA LMF. The configuration data and code loads
used for normal operation could be different from those stored in the
CDMA LMF files. By resetting all devices, the required data and code
can be loaded from the CBSC when spans are again active.
To reset all devices and have the OMCR/CBSC bring up the site
remotely, perform the procedure in Table 5-4.
Table 5-4: Reset BTS Devices and Remote Site Initialization
Step Action
1Terminate the CDMA LMF session by following the procedures in Table 5-6.
2NOTE
In the following step, performing Table 2-6 DC voltage measurements other than those using the MAP
VOLT and AMP indicators is not necessary if DC power system components have not been replaced
during the optimization and/or ATP process.
Cycle BTS power off, as specified in Table 2-9, and on, as specified in Table 2-5, Table 2-6, and step 1
of Table 2-7, respectively.
3Reconnect spans by following the procedure in Table 5-7.
4Notify the OMCR/CBSC to take control of the site and download code and data to the BTS.
5Verify the CBSC can communicate with the GLIs.
Bringing Modules into Service
with the CDMA LMF
Whenever possible, have the CBSC/MM bring up the site
and enable all devices at the BTS.
