LMF Operating System Installation

This section provides information and instructions for installing and
updating the LMF software and files.

68P09258A31–A

NOTE

First Time Installation Sequence:

1. Install Java Runtime Environment (JRE)

2. Install U/WIN K–shell emulator

3. Install LMF application programs

4. Install/create BTS folders

3

NOTE

Any time you install U/WIN, you must install the LMF software
because the installation of the LMF 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.

Follow the procedure in Table 3-1 to install the LMF application
program using the LMF CD ROM.

Table 3-1: Install LMF using CD ROM

n Step Action

1 Insert the LMF CD ROM disk into your disk drive and perform the

following as required:

1a – If the Setup screen appears, follow the instructions displayed on

the screen.

1b – If the Setup screen is not displayed, proceed to Step 2.

2 Click on the Start button.

3 Select Run.

4 Enter d:\autorun in the Open box and click OK.

NOTE

If applicable, replace the letter d with the correct CD ROM drive
letter.

Copy BTS and CBSC CDF (or NECF) Files to the LMF Computer

Before logging on to a BTS with the LMF 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 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 LMF computer.

NOTE

NOTE

– If the LMF 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 LMF:

S 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.

S The 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.

The procedure in Table 3-2 lists the steps required to transfer the CDF
files from the CBSC to the LMF computer. For further information, refer
to the LMF Help function on–line documentation.

3

Table 3-2: Copying CDF or NECF Files to the LMF Computer

n Step Action

AT THE CBSC:

1 Login to the CBSC workstation.

2 Insert a DOS–formatted floppy diskette in the workstation drive.

3 Type eject –q and press the Enter key.

4 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.

5 Change 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.

Table 3-2: Copying CDF or NECF Files to the LMF Computer

n ActionStep

7 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 <source filename> /floppy/no_name/<target filename>
(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

3

editor because Unix files do not contain line feed characters. Editing copied CDF files on the LMF
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).

8 Repeat Steps 5 through 7 for each bts–# that must be supported by the LMF computer.

9 When all required files have been copied to the diskette type eject and press the Enter key.

10 Remove the diskette from the CBSC drive.

AT THE LMF:

11 If it is not running, start the Windows operating system on the LMF computer.

12 Insert the diskette containing the bts-#.cdf (or bts–#.necf) and cbsc-#.cdf files into the LMF

computer.

13 Using MS Windows Explorer, create a corresponding bts–# folder in the <x>:\<lmf home

directory>\cdma directory for each bts-#.cdf (or bts–#.necf) and 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 <x>:\<lmf home directory>\cdma\bts–# folders created in Step 13.

Creating a Named HyperTerminal Connection for MMI Connection

Confirming or changing the configuration data of certain BTS Field
Replaceable Units (FRU) requires establishing an MMI communication
session between the LMF and the FRU. Using features of the Windows
operating system, the connection properties for an MMI session can be
saved on the 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 procedure in Table 3-3 to establish a named HyperTerminal
connection and create a Windows desktop shortcut for it.

Span Lines – Interface and Isolation

T1/E1 Span Interface

Span Lines – Interface and Isolation68P09258A31–A

NOTE

Each frame is equipped with one Site I/O and two Span I/O boards. The
Span I/O J1 connector provides connection of 25 pairs of wire. A GLI
card can support up to six spans. In the SC 4812T configuration, the odd
spans (1, 3, and 5) terminate on the Span “A” I/O; and the even spans (2,
4, and 6) terminate on the Span “B” I/O.

Before connecting the LMF to the frame LAN, the OMC/CBSC must
disable the BTS and place it OOS to allow the LMF to control the
CDMA BTS. This prevents the CBSC from inadvertently sending
control information to the CDMA BTS during LMF based tests. Refer to
Figure 3-2 and Figure 3-3 as required.

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 span cable connectors from the Span I/O cards
(see Figure 3-2).

Figure 3-2: Span I/O Board T1 Span Isolation

At active sites, the OMC/CBSC must disable the BTS and place

it out of service (OOS). DO NOT remove the 50–pin TELCO
cable connected to the BTS frame site I/O board J1 connector
until the OMC/CBSC has disabled the BTS!

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 <x>:\<lmf home directory>\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.

RFDS Display – If an RFDS is included in the CDF/NECF file, an
RFDS tab labeled with “RFDS,” a dash and the BTS number–frame
number combination (for example, RFDS–812–1) will be displayed.

Understanding GUI Operation

The following screen captures are provided to help understand how the
GUI operates:

– Figure 3-4 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 3-5 depicts the Self-Managed Network Elements (NEs) state

of a packet mode SC4812T. Note that an “X” is on the front of each
card that is under Self–Managed Network Elements (NEs) control

3

by the GLI3 card.

– Figure 3-6 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 3-5 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
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 3-7 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. Due to architectural limitations, the
GUI must be started before the CLI if you want the GUI and CLI to use
the same handler. When the CLI is launched after the GUI, the CLI
automatically finds and uses an in–progress login session with a BTS
initiated under the GUI. This allows the use of the GUI and the CLI in
the same BTS login session. If a CLI handler is already running when
the GUI is launched (this happens if the CLI window is already running
when the user starts the GUI, or if another copy of the GUI is already
running when the user starts the GUI), a dialog window displays the
following warning message:

The CLI handler is already running.
This may cause conflicts with the LMF.
Are you sure you want to start the application?
Yes No

Using the LMF68P09258A31–A

3

This window also contains Yes and No buttons. Selecting Ye s starts the
application. Selecting No terminates the application.

CLI Format Conventions

The CLI command syntax is as follows:

S verb
S device including device identifier parameters
S switch
S option parameters consisting of:

– keywords

– equals signs (=) between the keywords and the parameter values

– parameter values

Spaces are required between the verb, device, switch, and option
parameters. A hyphen is required between the device and its identifiers.
Following is an example of a CLI command.

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.

3

S A bts-nnn folder with the correct CDF/NECF and CBSC files exists.
S The LMF computer was connected to the BTS before starting the

Windows operating system and the LMF software. If necessary, restart
the computer after connecting it to the BTS in accordance with
Table 3-5 and Figure 3-3.

CAUTION

Be sure that the correct bts–#.cdf/necf and cbsc–#.cdf file are
used for the BTS. These should be the CDF/NECF files that are
provided for the BTS by the CBSC. Failure to use the correct
CDF/NECF files can result in invalid optimization. Failure to

use the correct CDF/NECF files to log into a live
(traffic–carrying) site can shut down the site.

Logging Out

Using the LMF68P09258A31–A

Logging out of a BTS is accomplished differently for the GUI and CLI
operating environments.

NOTE

The GUI and CLI environments use the same connection to a
BTS. If a GUI and the CLI session are running for the same BTS
at the same time, logging out of the BTS in either environment
will log out of it for both. When either a login or logout is
performed in the CLI window, there is no GUI indication that the
login or logout has occurred.

Logging Out of a BTS from the GUI Environment

Follow the procedure in Table 3-8 to logout of a BTS when using the
GUI environment.

Download the BTS

Overview

Download the BTS68P09258A31–A

Before a BTS can operate, each equipped device must contain device
initialization (ROM) code. ROM code is loaded in all devices during
manufacture or factory repair, or, for software upgrades, from the CBSC
using the DownLoad Manager (DLM). Device application (RAM) code
and data must be downloaded to each equipped device by the user before
the BTS can be made fully functional for the site where it is installed.

ROM Code

NOTE

3

Downloading ROM code to BTS devices from the LMF is NOT routine
maintenance nor a normal part of the optimization process. It is only

done in unusual situations where the resident ROM code in the device
does not match the release level of the site operating software AND the
CBSC cannot communicate with the BTS to perform the download.

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

Appendix G.

Before ROM code can be downloaded from the LMF, the correct ROM
code file for each device to be loaded must exist on the LMF computer.
ROM code must be manually selected for download.

The ROM code file is not available for GLI3s. GLI3s are ROM
code loaded at the factory.

ROM code can be downloaded to a device that is in any state. After the
download is started, the device being downloaded will change to
OOS_ROM (blue). The device will remain OOS_ROM (blue) when the
download is completed. A compatible revision–level RAM code must
then be downloaded to the device. Compatible code loads for ROM and
RAM must be used for the device type to ensure proper performance.
The compatible device code release levels for the BSS software release
being used are listed in the Version Matrix section of the SCt CDMA
Release Notes (supplied on the tape or CD–ROM containing the BSS
software).

RAM Code

Oct 2003

Before RAM code can be downloaded from the LMF, the correct RAM
code file for each device must exist on the LMF computer. RAM code
can be automatically or manually selected depending on the Device
menu item chosen and where the RAM code file for the device is stored
in the LMF file structure. The RAM code file will be selected
automatically if the file is in the <x>:\<lmf home
directory>\cdma\loads\n.n.n.n\code folder (where n.n.n.n is the
download code version number that matches the “NextLoad” parameter
of the CDF file). The RAM code file in the code folder must have the
correct hardware bin number for the device to be loaded.

RAM code can be downloaded to a device that is in any state. After the
download is started, the device being downloaded changes to OOS-ROM
(blue). When the download is completed successfully, the device will
change to OOS-RAM (yellow).

68P09258A31–A

When code is downloaded to an MGLI or GLI, the LMF automatically
also downloads data and then enables the MGLI. When enabled, the
MGLI will change to INS_ACT (bright green). A redundant GLI will
not be automatically enabled and will remain OOS_RAM (yellow).
When the redundant GLI is manually commanded to enable through the
LMF, it will change state to INS_SBY (olive green).

For non–MGLI devices, data must be downloaded after RAM code is
downloaded. To download data, the device state must be OOS–RAM
(yellow).

The devices to be loaded with RAM code and data are:

3

S Master Group Line Interface (MGLI2 or MGLI3)
S Redundant GLI (GLI2 or GLI3)
S Clock Synchronization Module (CSM) (Only if new revision code

must be loaded)

S Multi Channel Card (MCC24E, MCC8E or MCC–1X)
S Broadband Transceiver (BBX2 or BBX–1X)
S Test Subscriber Interface Card (TSIC) – if RFDS is installed

NOTE

The MGLI must be successfully downloaded with code and data,
and put INS before downloading any other device. The
download code process for an MGLI automatically downloads
data and enables the MGLI before downloading other devices.
The other devices can be downloaded in any order.

Enable CSMs

Download the BTS68P09258A31–A

NOTE

– CSMs are code loaded at the factory. This data is retained

in EEPROM. The download code procedure is required in
the event it becomes necessary to code load CSMs with
updated software versions. Use the status function to
determine the current code load versions.

– The CSM(s) to be enabled must have been downloaded

with code (Yellow, OOS–RAM) and data.

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 CSM2 card is required when using the R–GPS. The GPS receiver
(mounted on CSM–1) is the primary timing reference and synchronizes
the entire cellular system. CSM–2 provides redundancy but does not
have a GPS receiver.

The BTS may be equipped with a remote GPS, LORAN–C LFR, HSO
10 MHz Rubidium source, or HSOX for expansion frames, which the
CSM can use as a secondary timing reference. In all cases, the CSM
monitors and determines what reference to use at a given time.

Follow the procedure in Table 3-16 to enable the CSMs.

Table 3-16: Enable CSMs

n Step Action

1 Click on the target CSM (CSM–2 first, if equipped with two CSMs).

2 From the Device pull down, select Enable.

– A status report is displayed confirming change in the device(s) status.

– Click OK to close the status report window.

NOTE

– The board in slot CSM 1 interfaces with the GPS receiver. The enable sequence for this board can

take up to one hour (see below).

– FAIL may be shown in the status report table for a slot CSM 1 enable action. If

Lock is shown in the Description field, the CSM changes to the Enabled state after phase lock is

achieved.

* IMPORTANT

– The GPS satellite system satellites are not in a geosynchronous orbit and are maintained and

operated by the United States Department of Defense (D.O.D.). The D.O.D. periodically alters
satellite orbits; therefore, satellite trajectories are subject to change. A GPS receiver that is INS
contains an “almanac” that is updated periodically to take these changes into account.

– If a GPS receiver has not been updated for a number of weeks, it may take up to an hour for the

GPS receiver “almanac” to be updated.

– Once updated, the GPS receiver must track at least four satellites and obtain (hold) a 3–D position

fix for a minimum of 45 seconds before the CSM will come in service. (In some cases, the GPS
receiver needs to track only one satellite, depending on accuracy mode set during the data load).

CSM System Time – GPS & LFR/HSO Verification68P09258A31–A

CSM System Time – GPS & LFR/HSO Verification

CSM & LFR Background

The primary function of the Clock Synchronization Manager (CSM)
boards (slots 1 and 2) is to maintain CDMA system time. The CSM in
slot 1 is the primary timing source while slot 2 provides redundancy. The
CSM2 card (CSM second generation) is required when using the remote
GPS receiver (R–GPS). R–GPS uses a GPS receiver in the antenna head
that has a digital output to the CSM2 card. CSM2 can have a daughter
card as a local GPS receiver to support an RF–GPS signal.

The CSM2 switches between the primary and redundant units (slots 1
and 2) upon failure or command. CDMA Clock Distribution
Cards (CCDs) buffer and distribute even–second reference and 19.6608
MHz clocks. CCD–1 is married to CSM–1 and CCD–2 is married to
CSM 2. A failure on CSM–1 or CCD–1 cause the system to switch to
redundant CSM–2 and CCD–2.

In a typical operation, the primary CSM locks its Digital Phase Locked
Loop (DPLL) circuits to GPS signals. These signals are generated by
either an on–board GPS module (RF–GPS) or a remote GPS receiver
(R–GPS). The CSM2 card is required when using the R–GPS. DPLL
circuits employed by the CSM provide switching between the primary
and redundant unit upon request. Synchronization between the primary
and redundant CSM cards, as well as the LFR or HSO back–up source,
provides excellent reliability and performance.

3

Front Panel LEDs

Each CSM board features an ovenized, crystal oscillator that provides

19.6608 MHz clock, even second tick reference, and 3 MHz sinewave
reference, referenced to the selected synchronization source (GPS,
LORAN–C Frequency Receiver (LFR), or High Stability Oscillator
(HSO), T1 Span, or external reference oscillator sources).

The 3 MHz signals are also routed to the RDM EXP 1A & 1B
connectors on the top interconnect panel for distribution to co–located
frames at the site.

Fault management has the capability of switching between the GPS
synchronization source and the LFR/HSO backup source in the event of
a GPS receiver failure on CSM–1. During normal operation, the CSM–1
board selects GPS as the primary source (see Table 3-20). The source
selection can also be overridden via the LMF or by the system software.

The status of the LEDs on the CSM boards are as follows:

S Steady Green – Master CSM locked to GPS or LFR (INS).
S Rapidly Flashing Green – Standby CSM locked to GPS or LFR

(STBY).

S Flashing Green/Rapidly Flashing Red – CSM OOS–RAM attempting

to lock on GPS signal.

Oct 2003

S Rapidly Flashing Green and Red – Alarm condition exists. Trouble

Notifications (TNs) are currently being reported to the GLI.

CSM System Time – GPS & LFR/HSO Verification

68P09258A31–A

Low Frequency Receiver/High Stability Oscillator (LFR/HSO)

The CSM and the LFR/HSO – The CSM performs the overall
configuration and status monitoring functions for the LFR/HSO. In the
event of GPS failure, the LFR/HSO is capable of maintaining
synchronization initially established by the GPS reference signal.

LFR – The LFR requires an active external antenna to receive
LORAN–C RF signals. Timing pulses are derived from this signal,
which is synchronized to Universal Time Coordinates (UTC) and GPS
time. The LFR can maintain system time indefinitely after initial GPS

3

lock.

HSO – The HSO is a high stability 10 MHz oscillator with the necessary
interface to the CSMs. The HSO is typically installed in those
geographical areas not covered by the LORAN–C system. Since the
HSO is a free–standing oscillator, system time can only be maintained
for 24 hours after 24 hours of GPS lock

Upgrades and Expansions: LFR2/HSO2/HSOX

NOTE

LFR2/HSO2 (second generation cards) both export a timing signal to the
expansion or logical BTS frames. The associated expansion or logical
frames require an HSO–expansion (HSOX) whether the starter frame has
an LFR2 or an HSO2. The HSOX accepts input from the starter frame
and interfaces with the CSM cards in the expansion frame. LFR and
LFR2 use the same source code in source selection (see Table 3-19).
HSO, HSO2, and HSOX use the same source code in source selection
(see Table 3-19).

Allow the base site and test equipment to warm up for 60
minutes after any interruption in oscillator power. CSM board
warm-up allows the oscillator oven temperature and oscillator
frequency to stabilize prior to test. Test equipment warm-up
allows the Rubidium standard timebase to stabilize in frequency
before any measurements are made.

The HSO module is a full–size card that resides in the C–CCP Shelf.
This completely self contained high stability 10 MHz oscillator
interfaces with the CSM via a serial communications link. The CSM
handles the overall configuration and status monitoring functions of the
HSO. In the event of GPS failure, the HSO is capable of maintaining
synchronization initially established by the GPS reference signal for a
limited time.

The HSO is typically installed in those geographical areas not covered
by the LORAN–C system and provides the following major functions:

S Reference oscillator temperature and phase lock monitor circuitry
S Generates a highly stable 10 MHz sine wave.
S Reference divider circuitry converts 10 MHz sine wave to 10 MHz

TTL signal, which is divided to provide a 1 PPS strobe to the CSM.

Equipment Warm-up

68P09258A31–A

NOTE

WARNING

3

To assure BTS stability and contribute to optimization accuracy
of the BTS, warm-up the BTS test equipment prior to
performing the BTS optimization procedure as follows:

– Agilent E7495A for a minimum of 30 minutes

– All other test sets for a minimum of 60 minutes

Time spent running initial or normal power-up, hardware/
firmware audit, and BTS download counts as warm-up time.

Before installing any test equipment directly to any BTS TX
OUT connector, verify there are no CDMA channels keyed.

– At active sites, have the OMC-R/CBSC place the antenna

(sector) assigned to the LPA under test OOS. Failure to do
so can result in serious personal injury and/or equipment
damage.

Automatic Cable Calibration Set–up

Figure 3-12 through Figure 3-15 show the cable calibration setup for
various supported test sets. The left side of the diagram depicts the
location of the input and output ports of each test set, and the right side
details the set up for each test.

Manual Cable Calibration

If manual cable calibration is required, refer to the procedures in
Appendix F.

Set. The 10dB attenuator is used only for the cable
calibration procedure, not with the test cables for
TX calibration and ATP tests.

Proper test equipment calibration ensures that the test equipment and
associated test cables do not introduce measurement errors, and that
measurements are correct.

NOTE

3

CAUTION

NOTE

This procedure must be performed prior to beginning the optimization.
Verify all test equipment (including all associated test cables and
adapters actually used to interface all test equipment and the BTS) has
been calibrated and maintained as a set.

If 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.

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.

Calibration of the communications system analyzer (or
equivalent test equipment) must be performed at the site before
calibrating the overall test equipment set. Calibrate the test
equipment after it has been allowed to warm–up and stabilize for
a minimum of 60 minutes.

Calibration Procedures Included

Automatic

Procedures included in this section use the LMF automated calibration
routine to determine path losses of the supported communications
analyzer, power meter, associated test cables, adapters, and (if used)
antenna switch that make up the overall calibrated test equipment set.
After calibration, the gain/loss offset values are stored in a test
measurement offset file on the LMF computer.

Manual

Agilent E4406A Transmitter Tester – The E4406A does not support
the power level zeroing calibration performed by the LMF. If this
instrument is to be used for Bay Level Offset calibration and calibration
is attempted with the LMF Calibrate Test Equipment function, the
LMF will return a status window failure message stating that zeroing
power is not supported by the E4406A. Refer to the Equipment
Calibration section of Appendix F for instructions on using the
instrument’s self–alignment (calibration) function prior to performing
Bay Level Offset calibration.

Power Meters – Manual power meter calibration procedures to be
performed prior to automated calibration are included in the Equipment
Calibration section of Appendix F.

Calibrating Cables Overview

Test Set Calibration68P09258A31–A

The LMF Cable Calibration function is used to measure the path loss (in
dB) for the TX and RX cables, adapters, directional couplers, and
attenuators that make up the cable configurations used for testing. A
communications system analyzer is used to measure the loss of both the
TX test cable and the RX test cable configurations. LMF cable
calibration consists of the following processes:

Measure the loss of a short cable

This is done to compensate for any measurement error of the
communications system analyzer. The short cable, which is used only for
the calibration process, is connected in series with both the TX and RX
test cable configurations when they are measured.

The measured loss of the TX and RX test cable configurations minus the
measured loss of the short cable equals the actual loss of the
configurations. This is done so that any error in the analyzer
measurement is eliminated from both the TX and RX measurements.

Measure the loss of the short cable plus the RX test
cable configuration

3

The RX test cable configuration normally consists only of a coax cable
with type–N connectors that is long enough to reach from the BTS RX
connector to the test equipment.

When the BTS antenna connectors carry duplexed TX and RX signals, a
directional coupler is required and an additional attenuator may also be
required (for certain BTS types) for the RX test cable configuration.
These additional items must be included in the path loss measurement.

Measure the loss of the short cable plus the TX test
cable configuration

The TX test cable configuration normally consists of two coax cables
with type–N connectors, a directional coupler, a termination load with
sufficient rating to dissipate the BTS output power, and an additional
attenuator, if required by the BTS type. The total path loss of the TX test
configuration must be as required for the BTS (normally 30 or 50 dB).

The Motorola Cybertest analyzer differs from other communications
system analyzers because the required attenuation/load is built into the
test set. Because of this, the Cybertest TX test configuration consists
only of the required length coax cable.

Bay Level Offset Calibration

Introduction

Bay Level Offset (BLO) calibration is the central activity of the
optimization process. BLO calibration compensates for normal
equipment variations within the BTS RF paths and assures the correct
transmit power is available at the BTS antenna connectors to meet site
performance requirements.

RF Path Bay Level Offset Calibration

Bay Level Offset Calibration68P09258A31–A

Calibration identifies the accumulated gain in every transmit path (BBX
slot) at the BTS site and stores that value in a BLO database calibration
table in the LMF. The BLOs are subsequently downloaded to each BBX.

For starter frames, each receive path starts at a BTS RX antenna port and
terminates at a backplane BBX slot. Each transmit path starts at a BBX
backplane slot, travels through the Power Amplifier (PA) and terminates
at a BTS TX antenna port.

For expansion frames each receive path starts at the BTS RX port of the
cell site starter frame, travels through the frame-to-frame expansion
cable, and terminates at a backplane BBX slot of the expansion frame.
The transmit path starts at a BBX backplane slot of the expansion frame,
travels though the PA and terminates at a BTS TX antenna port of the
same expansion frame.

Calibration identifies the accumulated gain in every transmit path (BBX
slot) at the BTS site and stores that value in a BLO database. Each
transmit path starts at a C–CCP shelf backplane BBX slot, travels
through the PA, and ends at a BTS TX antenna port. When the TX path
calibration is performed, the RX path BLO is automatically set to the
default value.

At omni sites, BBX slots 1 and 13 (redundant) are tested. At sector sites,
BBX slots 1 through 12, and 13 (redundant) are tested. Only those slots
(sectors) actually equipped in the current CDF are tested, regardless of
physical BBX board installation in the slot.

3

When to Calibrate BLOs

Oct 2003

Calibration of BLOs is required:

S After initial BTS installation
S Once each year
S After replacing any of the following components or associated

interconnecting RF cabling:
– BBX board
– C–CCP shelf
– CIO card
– CIO to Power Amplifier backplane RF cable
– PA backplane
–PA
– TX filter / TX filter combiner
– TX thru-port cable to the top of frame

Bay Level Offset Calibration

TX Path Calibration

68P09258A31–A

The TX Path Calibration assures correct site installation, cabling, and the
first order functionality of all installed equipment. The proper function
of each RF path is verified during calibration. The external test
equipment is used to validate/calibrate the TX paths of the BTS.

WARNING

Before installing any test equipment directly to any TX OUT
connector you must first verify that there are no CDMA
channels keyed. Have the OMC–R place the sector assigned to
the LPA under test OOS. Failure to do so can result in serious
personal injury and/or equipment damage.

3

CAUTION

NOTE

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.

At new site installations, to facilitate the complete test of each
CCP shelf (if the shelf is not already fully populated with BBX
boards), move BBX boards from shelves currently not under test
and install them into the empty BBX slots of the shelf currently
being tested to insure that all BBX TX paths are tested.

– This procedure can be bypassed on operational sites that are

due for periodic optimization.

– Prior to testing, view the CDF file to verify the correct

BBX slots are equipped. Edit the file as required to include
BBX slots not currently equipped (per Systems
Engineering documentation).

BLO Calibration Data File

NOTE

During the calibration process, the LMF creates a bts–n.cal calibration
(BLO) offset data file in the bts–n folder. After calibration has been
completed, this offset data must be downloaded to the BBXs using the
Download BLO function. An explanation of the file is shown below.

Due to the size of the file, Motorola recommends that you print
out a hard copy of a bts.cal file and refer to it for the following
descriptions.

The CAL file is subdivided into sections organized on a per slot basis (a
slot Block).

Slot 1 contains the calibration data for the 12 BBX slots. Slot 20
contains the calibration data for the redundant BBX. Each BBX slot
header block contains:

S A creation Date and Time – broken down into separate parameters of

createMonth, createDay, createYear, createHour, and createMin.

S The number of calibration entries – fixed at 720 entries corresponding

to 360 calibration points of the CAL file including the slot header and
actual calibration data.

S Ten calibration points per sector are supported for each branch. Two

entries are required for each calibration point.

S The first value (all odd entries) refer to the CDMA channel

(frequency) where the BLO is measured. The second value (all even
entries) is the power set level. The valid range for PwrLvlAdj is from
2500 to 27500 (2500 corresponds to –125 dBm and 27500
corresponds to +125 dBm).

S The 20 calibration entries for each sector/branch combination must be

stored in order of increasing frequency. If less than 10 points
(frequencies) are calibrated, the largest frequency that is calibrated is
repeated to fill out the 10 points.

Example:

C[1]=384, odd cal entry

= 1 ‘‘calibration point”

C[2]=19102, even cal entry

C[3]=777,
C[4]=19086,
.
.
C[19]=777,
C[20]=19086, (since only two cal points were calibrated this

would be repeated for the next 8 points)

S When the BBX is loaded with image = data, the cal file data for the

BBX is downloaded to the device in the order it is stored in the cal
file. TxCal data is sent first, C[1] – C[240]. Sector 1’s ten calibration
points are sent (C[1] – C[20]) followed by sector 2’s ten calibration
points (C[21] – C[40]), etc. The RxCal data is sent next (C[241] –
C[480]), followed by the RxDCal data (C[481] – C[720]).

S Temperature compensation data is also stored in the cal file for each

set.
