DRAFT
Introduction
The following information is used to check for any electrical short
circuits and to verify the operation and tolerances of the cellsite and BTS
power supply units before applying power for the first time. It contains
instructional information on the initial proper power up procedures for
the SC 4812ET power cabinet and RF cabinet. Also presented are tests
to be preformed on the power cabinet. Please pay attention to all
cautions and warning statements in order to prevent accidental injury to
personnel.
Required Tools
The following tools are used in the procedures.
SDC current clamp (600 Amp capability with jaw size to accommodate
2/0 cable).
SHot Air Gun – (optional for part of the Alarm Verification)
SDigital Multimeter (DMM)
Cabling Inspection
Using the site-specific documentation generated by Motorola Systems
Engineering, verify that the following cable systems are properly
connected:
SReceive RF cabling – up to 12 RX cables
STransmit RF cabling – up to six TX cables
For positive power applications (+27 V):
SThe positive power cable is red.
SThe negative power cable is black. (The black power
cable is at ground potential.)
IMPORTANT
*
Initial Inspection and Setup
Ensure all battery breakers for unused battery positions are
open (pulled out) during any part of the power up process,
and remain in the off position when leaving the site.
CAUTION
Table 2-2: Initial Inspection and Setup
Step Action
1Verify that ALL AC and DC breakers are turned OFF in both the Power and RF cabinets. Verify that
the DC power cables between the Power and RF cabinets are connected with the correct polarity
2The RED cables connect to the uppermost three (3) terminals (marked +) in both cabinets. Confirm
that the split phase 240/120 AC supply is correctly connected to the AC load center input.

Failure to connect the proper AC feed will damage the
surge protection module inside the AC load center.
CAUTION
Power Up Sequence
The first task in the power up sequence is to apply AC power to the
Power cabinet. Once power is applied a series of AC Voltage
measurements is required.
Table 2-3: AC Voltage Measurements
Step Action
1Measure the AC voltages connected to the AC load center (access the terminals from the rear of the
cabinet after removing the AC load center rear panel). See Figure 2-2.
2Measure the AC voltage from terminal L1 to neutral. This voltage should be in the range of nominally
115 to 120 V AC.
3Measure the AC voltage from terminal L1 to ground. This voltage should be in the range of nominally
115 to 120 V AC.
4Measure the AC voltage from terminal L2 to neutral. This voltage should be in the range of nominally
115 to 120 V AC.
5Measure the AC voltage from terminal L2 to ground. This voltage should be in the range of nominally
115 to 120 V AC.
6Measure L1 – L2 – should be from 208 to 240 V AC.
If the AC voltages are in excess of 120 V (or exceed
200 V) when measuring between terminals L1 or L2 to
neutral or ground, STOP and Do Not proceed until the
cause of the higher voltages are determined. The power
cabinet WILL be damaged if the Main breaker is turned
on with excessive voltage on the inputs.

Applying AC Power
Once AC Voltage Measurements are complete, apply AC power to the
Power Cabinet. Table 2-4 provides the procedure for applying AC
power.
Table 2-4: Applying AC Power
Step Action
1When the input voltages are verified as correct, turn the Main AC breaker (located on the front of the
AC Load Center) ON. Observe that all eight (8) green LEDs on the front of the AC Load Center are
illuminated (see Figure 2-7).
2Turn Rectifier 1 and Rectifier 2 AC branch breakers (on the AC Load Center) ON. All the installed
rectifier modules (see Figure 2-7) will start up and should each have two green LEDs (DC and Power)
illuminated.
3Turn the Meter Alarm Panel module, ON (see Figure 2-3), while observing the K2 contact in the
PDA assembly (see Figure 2-9). The contact should close. The Meter Alarm Panel voltage meter
should read approximately 27.4 + 0.2 Vdc.
4Turn the Temperature Compensation Panel (TCP) ON, (see Figure 2-4). Verify that the Meter Alarm
Control Panel does not have any alarm LEDs illuminated.
5Check the rectifier current bargraph displays (green LED display on the rectifier module). None
should be illuminated at this point.
If batteries are fitted, turn on the two battery heater AC
breakers on the AC Load Center.

Power Cabinet Power Up
Tests
Table 2-5 lists the step–by–step instructions for Power Up Tests.
Table 2-5: Power Cabinet Power Up Tests
Step Action
1Probe the output voltage test point on the Meter Alarm Panel while pressing the 25° C set button on
the TCP (see Figure 2-4). The voltage should read 27.4 + 0.2 Vdc. Adjust Master Voltage on Meter
Alarm Panel if necessary. Release the TCP 25° C set button.
2Depending on the ambient temperature, the voltage reading may now change by up to + 1.5 V
compared to the reading just measured. If it is cooler than 25_C, the voltage will be higher, and if it is
warmer than 25_C, the voltage will be lower.
3Ensure the RF cabinet 400 Amp main DC breaker is OFF.
4Close the three (3) Main DC breakers on the Power Cabinet ONLY. Close by holding in the reset
button on the front of the PDA, and engaging one breaker at a time.
5Measure the voltage between the + and – terminals at the rear of the Power Cabinet and the RF
Cabinet, observing that the polarity is correct. The voltage should be the same as the measurement in
step 2.
6Place the probes across the black and red battery buss bars in each battery compartment. Place the
probe at the bottom of the buss bars where the cables are connected. The DC voltage should measure
the same as the previous step.

DC Power Pre-test (BTS Frame) Before applying any power to the BTS cabinet, verify there are no shorts
in the RF or power DC distribution system (see Figure 2-5).
Table 2-6: DC Power Pre–test (BTS Frame)
Step Action
1Physically verify that all AC rectifiers supplying power to the RF cabinets are OFF or disabled (see
Figure 2-5). There should be no 27 Vdc on DC feed terminals.
2On each RF cabinet:
SUnseat all circuit boards/ modules in the distribution shelf, transceiver shelf, and Single Carrier
Linear Power Amplifier (SCLPA) shelves, but leave them in their associated slots.
SUnseat all circuit boards (except CCD and CIO cards) in the C–CCP shelf and LPA shelves, but
leave them in their associated slots.
SSet C–CCP shelf breakers to the OFF position by pulling out power distribution breakers (labeled
C–CCP 1, 2, 3 – located on the power distribution panel).
SSet LPA breakers to the OFF position by pulling out power distribution breakers (8 breakers,
labeled 1A–1B through 4C–4D – located on the power distribution panel).
3Verify that the resistance from the power (+) feed terminals with respect to the ground terminal on the
cabinet measures > 500 Ω (see Figure 2-5).
SIf reading is < 500 Ω, a short may exist somewhere in the DC distribution path supplied by the
breaker. Isolate the problem before proceeding. A reading > 3 MΩ could indicate an open (or
missing) bleeder resistor (installed across the filter capacitors behind the breaker panel).
4Set the 400 Amp Main Breaker and the C–CCP breakers (C–CCP 1, 2, 3) to the ON position by
pushing them IN one at a time. Repeat step 3 after turning on each breaker.
* IMPORTANT
If, after inserting any board/module, the ohmmeter stays at 0 Ω, a short probably exists in that
board/module. Replace the suspect board/module and repeat the test. If test still fails, isolate the
problem before proceeding.
5Insert and lock the DC/DC converter modules into their associated slots one at a time. Repeat step3
after inserting each module.
SA typical response is that the ohmmeter will steadily climb in resistance as capacitors charge, finally
indicating approximately 500 Ω.
! CAUTION
Verify the correct power/converter modules by observing the locking/retracting tabs appear as follows:
– (in +27 volt systems)
6Insert and lock all remaining circuit boards and modules into their associated slots in the C–CCP shelf.
Repeat step 3 after inserting and locking each board or module.
SA typical response is that the ohmmeter will steadily climb in resistance as capacitors charge,
stopping at approximately 500 Ω..

RF Cabinet Power Up
Table 2-7 covers the procedures for properly powering up the RF
Cabinet.
Table 2-7: RF Cabinet Power Up
Step Action
1Ensure the 400 Amp Main DC breaker and all other breakers in the RF Cabinet are OFF.
2Proceed to the DC Power Pre–test (BTS Frame) sequence (see Table 2-6) (for initial power–up as
required).
3Ensure the power cabinet is turned on (see Table 2-5). Verify that 27 volts is applied to the terminals
on the back of the RF cabinet.
4Engage the main DC circuit breaker on the RF cabinet (see Figure 2-5).
5On each RF cabinet:
SSet C–CCP shelf breakers to the ON position by pushing them in one at a time (labeled
C–CCP 1, 2, 3 – located on the power distribution panel).
SSet LPA breakers to the ON position by pushing them in one at a time (8 breakers, labeled 1A–1B
through 4C–4D – located on the power distribution panel).
SSet the two heat exchanger breakers to the ON position by pushing them in one at a time.
SSet the ETIB breaker to the ON position by pushing it in.
SSet the OPTION breaker to the ON position by pushing it in.

NOTE
For a three (3) sector carrier system, the voltage drop should be less than 0.2 V.
For a twelve (12) sector carrier system, the voltage drop should be less than 0.3 V.
7Using a DC current probe, measure the current in each of the six (6) DC cables that are connected
between the RF and Power Cabinet. The DC current measured should be approximately the same. If
there is a wide variation between one cable and the others (>20 A), check the tightness of the
connections (torque settings) at each end of the cable.

Battery Charge Test
(Connected Batteries)
Table 2-8 lists the step–by–step instructions for testing the batteries.
Table 2-8: Battery Charge Test (Connected Batteries)
Step Action
1Close the battery compartment breakers for connected batteries ONLY. This process should be
completed quickly to avoid individual battery strings with excess charge current
NOTE
If the batteries are sufficiently discharged, the battery circuit breakers may not engage individually
due to the surge current. If this condition is observed, turn off the Meter Alarm Panel power switch,
and then engage all the connected battery circuit breakers, the Meter Alarm Panel power switch
should then be turned ON.
2Using the DC current probe, measure the current in each of the battery string connections to the buss
bars in each battery cabinet. The charge current may initially be high but should quickly reduce in a
few minutes if the batteries have a typical new battery charge level.
3The current in each string should be approximately equal (+ 5 A).
4The bargraph meters on the rectifier modules can be used as a rough estimate of the total battery
charge current. Each rectifier module has eight (8) LEDs to represent the output current. Each
illuminated LED indicates that approximately 12.5% (1/8 or 8.75 A) of the rectifiers maximum (70 A)
current is flowing.
EXAMPLE:
Question: A system fitted with three (3) rectifier modules each have three bargraph LEDs
illuminated. What is the total output current into the batteries?
Answer: Each bargraph is approximately indicating 12.5% of 70 A, therefore, 3 X 8.75 equals
26.25 A. As there are three rectifiers, the total charge current is equal to (3 X 26.25 A) 78.75 A.
This charge current calculation only applies at this part of the start up procedure, when the RF Cabinet
is not powered on, and the power cabinet heat exchanger is turned off.
5Allow a few minutes to ensure that the battery charge current stabilizes before taking any further
action. Recheck the battery current in each string. If the batteries had a reasonable charge, the current
in each string should reduce to less than 5 A.
6Recheck the DC output voltage. It should remain the same as measured in step 4 of the Power Up
Test.
NOTE
If discharged batteries are installed, all bargraphs may be illuminated on the rectifiers during the
charge test. This indicates that the rectifiers are at full capacity and are rapidly charging the batteries.
It is recommended in this case that the batteries are allowed to charge and stabilize as in the above
step before commissioning the site. This could take several hours.
Battery Discharge Test
Perform the test procedure in Table 2-9 only when the battery current is
less than 5 A per string. Refer to Table 2-8 on the procedures for
checking current levels.

DRAFT
Table 2-9: Battery Discharge Test
Step Action
1Turn the battery test switch on the Meter Alarm Panel, ON (see Figure 2-3). The rectifier output
voltage and current should decrease by approximately 10% as the batteries assume the load. Alarms
for the Meter Alarm Panel may occur.
2Measure the individual battery string current using the DC current probe. The battery discharge
current in each string should be approximately the same (within + 5 A).
3Turn Battery Test Switch OFF.
Failure to turn OFF the Battery Test Switch before leaving
the site, will result in low battery capacity and reduce
battery life.

Optimization/Calibration – Introduction
Apr 2001 3-1
SCt4812ET BTS Optimization/ATP — CDMA LMF
DRAFT
Introduction
This chapter provides procedures for downloading system operating
software, set up of the supported test equipment, CSM reference
verification/optimization, and transmit/receive path verification.
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
*
Optimization Process
After a BTS is physically installed and the preliminary operations
(power up) have been completed, the CDMA LMF is used to calibrate
and optimize the BTS. The basic optimization process can be
accomplished as follows:
SDownload MGLI2–1 with code and data and then enable MGLI2–1.
SUse the status function and verify that all of the installed devices of
the following types respond with status information: CSM2, BBX2,
GLI2, and MCC (and TSU if RFDS is installed). If a device is
installed and powered up but is not responding and is colored gray in
the BTS display, the device is not listed in the CDF file. The CDF file
will have to be corrected before the device can be accessed by CDMA
LMF.
SDownload code and data to all devices of the following types:
– CSM2
– BBX
–GLI2 (other than MGLI2–1)
– MCC
SDownload the RFDS TSIC (if installed).
SVerify the operation of the GPS and HSO signals.
SEnable the following devices (in the order listed):
–Secondary CSM (slot 2)
–Primary CSM (slot 1)
–All MCCs
SConnect the required test equipment for a full optimization.
SSelect the test equipment.
SCalibrate the TX and RX test cables if they have not previously been
calibrated using the CDMA LMF that is going to be used for the
optimization/calibration. The cable calibration values can also be
entered manually.

Optimization/Calibration – Introduction – continued
DRAFT
SCt4812ET BTS Optimization/ATP — CDMA LMF Apr 2001

SSelect all of the BBXs and all of the MCCs and use the full
optimization function. The full optimization function performs TX
calibration, BLO download, TX audit, all TX tests, and all RX tests
for all selected devices.
SIf the TX calibration fails, repeat the full optimization for any failed
paths.
SIf the TX calibration fails again, correct the problem that caused the
failure and repeat the full optimization for the failed path.
SIf the TX calibration and audit portion of the full optimization passes
for a path but some of the TX or RX tests fail, correct the problem that
caused the failure and run the individual tests as required until all TX
and RX tests have passed for all paths.
Cell–site Types
Sites are configured as Omni/Omni or Sector/Sector (TX/RX). Each type
has unique characteristics and must be optimized accordingly.
Cell–site Data File
The CDF includes the following information:
SDownload instructions and protocol
SSite specific equipage information
SC–CCP shelf allocation plan
–BBX2 equipage (based on cell–site type) including redundancy
–CSM equipage including redundancy
–MCC (MCC24E, MCC8E or MCC–1X) channel element allocation
plan. This plan indicates how the C–CCP shelf is configured, and
how the paging, synchronization, traffic, and access channel
elements (and associated gain values) are assigned among the (up to
12) MCCs in the shelf.
SCSM equipage including redundancy
SEffective Rated Power (ERP) table for all TX channels to antennas
respectively. Motorola System Engineering specifies the ERP of a
transmit antenna based on site geography, antenna placement, and
government regulations. Working from this ERP requirement, the
antenna gain, (dependent on the units of measurement specified) and
antenna feed line loss can be combined to determine the required
power at the top of the BTS frame. The corresponding BBX2 output
level required to achieve that power level on any channel/sector can
also be determined.
Refer to the CDMA LMF Operator’s Guide, 68P64114A78,
for additional information on the layout of the LMF
directory structure (including CDF file locations and
formats).

BTS System Software
Download
BTS system software must be successfully downloaded to the BTS
processor boards before optimization can be performed. BTS operating
code is loaded from the LMF computer terminal.
Before using the LMF for optimization/ATP, the correct
bts–#.cdf and cbsc–#.cdf files for the BTS must be
obtained from the CBSC and put in a bts–# folder in the
LMF. Failure to use the correct CDF files can cause wrong
results. Failure to use the correct CDF files to log into a
live (traffic carrying) site can shut down the site.
IMPORTANT
*
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 CDMA LMF Operator’s Guide,
68P64114A78, or the LMF Help screen, for more information.
Site Equipage Verification
If you have not already done so, use an editor to view the CDF, and
review the site documentation. Verify the site engineering equipage data
in the CDF to the actual site hardware.
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.

Isolate BTS from T1/E1 Spans
–At active sites, the OMC/CBSC must disable the
BTS and place it out of service (OOS). DO NOT
remove the span surge protectors until the
OMC/CBSC has disabled the BTS.
IMPORTANT
*
Each frame is equipped with one 50–pair punch block for spans,
customer alarms, remote GPS, and power cabinet alarms. See Figure 3-2
and refer to Table 3-1 for the physical location and pin call–out
information. To disable the span, pull the surge protectors for the
respective span.
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.
Configure Channel Service
Unit
The M–PATH 537 Channel Service Unit (CSU) provides in–band
SNMP–managed digital service access to T1 and fractional T1 lines.
M–PATH units plug into the ADC Kentrox 2–slot frame (see
Figure 3-1).
Remote M–PATH management is available via SNMP over an in–band
data link on the T1 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.
Each 19 inch rack can support two CSU M–PATH 537 modules. Each
M–PATH 537 module supports one and only one span connection.
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 is supplied with each unit.

Setting the Control Port
Whichever control port is chosen, it must first be set up so the control
port switches 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” (leave the switch down for the
rear–panel DCE control port).
For more information, refer to the Kentrox Installation Guide, manual
number 65–77538001 which is provided with each CSU.

* IMPORTANT
First Time Installations:
–Install U/WIN (First)
–Install Java Runtime Environment (Second)
–Install LMF Software (Third)
–Install BTS Binaries (Fourth)
–Install/Create BTS Folders (Fifth)
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.
NOTE
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.
CDMA LMF Home Directory
The CDMA LMF installation program creates the default home directory
c:\wlmf, and installs the application files and subdirectories (folders)
in it. Because this can be changed at installation, the CDMA LMF home
directory will be referred to with the generic convention of:
<x>:\<lmf home directory>
Where:
<x> = the LMF computer drive letter where the CDMA LMF home
directory is located.
<lmf home directory> = the directory path or name where the CDMA
LMF is installed
The CDMA LMF installation program creates the default
home directory c:\wlmf when the CDMA LMF is
installed.

Copy CBSC CDF Files to the
LMF Computer
Before logging on to a BTS with the LMF 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 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.
*When copying CDF files, comply with the following to
prevent BTS login problems with the LMF.
– The numbers used in the bts–#.cdf and cbsc–#.cdf
filenames must correspond to the locally assigned numbers
for each BTS and its controlling CBSC.
– The generic cbsc–1.cdf file supplied with the 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 3-4 lists the steps required to transfer the CDF
files from the CBSC to the LMF computer. For any further information,
refer to the CDMA LMF Operator’s Guide (Motorola part number
68P64114A21) or the LMF Help screen..
Table 3-4: Copying CBSC CDF Files to the LMF
Step Action
1Login to the CBSC workstation.
2Insert a DOS–formatted floppy diskette in the workstation drive.
3 Type eject –q and press <Enter>.
4 Type mount and press <Enter>.
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 <Enter>.
6 Type ls and press the Enter key to display the list of files in the directory.

Table 3-4: Copying CBSC CDF Files to the LMF
Step Action
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 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/na_name)
8Repeat steps 5 through 7 for each bts–# that must be supported by the LMF.
9When all required files have been copied to the diskette, type eject and press <Enter>.
10 Remove the diskette from the CBSC drive.
11 If it is not running, start the Windows operating system on the LMF computer.
12 Insert the diskette containing the bts–#.cdf and cbsc–#.cdf files into the LMF computer.
13 Using Windows Explorer (or equivalent program), create a corresponding bts–# folder in the <lmf
home directory> directory for each bts–#.cdf/cbsc–#.cdf file pair copied from the CBSC.
14 Use Windows Explorer (or equivalent program) to transfer the cbsc–#.cdf and bts–#.cdf files from the
diskette to the corresponding <lmf home directory>\wlmf\cdma\bts–# folders created in step 13.
Creating a Named
HyperTerminal Connection for
MMI Connection
Confirming or changing the configuration data of certain BTS FRUs
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 procedures in Table 3-5 to establish a named HyperTerminal
connection and create a Windows desktop shortcut for it.

Pinging the Processors
For proper operation, the integrity of the Ethernet LAN A and B links
must be be verified. Figure 3-5 represents a typical BTS Ethernet
configuration. The drawing depicts one (of two identical) links, A and B.
Ping is a program that sends request packets to the LAN network
modules to get a response from the specified “target” module.
Follow the steps in Table 3-7 to ping each processor (on both LAN A
and LAN B) and verify LAN redundancy is working properly.
Always wear a conductive, high impedance wrist strap
while handling any circuit card/module to prevent damage
by ESD.

Using CDMA LMF
DRAFT
Apr 2001 3-21
SCt4812ET BTS Optimization/ATP — CDMA LMF
Basic LMF Operation
The terms “CDMA LMF” and “WinLMF” are
interchangeable
NOTE
The CDMA LMF allows the user to work in the two following operating
environments which are accessed using the specified desktop icon:
SGraphical User Interface (GUI) using the WinLMF icon
SCommand Line Interface (CLI) using the WinLMF CLI icon
The GUI is the primary optimization and acceptance testing operating
environment. The CLI environment provides additional capability to the
user to perform manually controlled acceptance tests and audit the
results of optimization and calibration actions.
Basic operation of the LMF GUI includes the following:
SSelecting and deselecting BTS devices
SEnabling devices
SDisabling devices
SResetting devices
SObtaining device status
SSorting a status report window
For detailed information on performing these and other LMF operations,
refer to the CDMA LMF Operator’s Guide, 68P64114A78.
Basic LMF Command Line
Interface (CLI) Operation
.
Both the GUI and the CLI use a program known as the handler. Only one
handler can be running at one time. The architectural design is such that
the GUI must be started before the CLI if you want the GUI and CLI to
use the same handler. When the CLI is launched after the GUI, the CLI
automatically finds and uses an in–progress login session with a BTS
initiated under the GUI. This allows the use of the GUI and the CLI in
the same BTS login session. If a CLI handler is already running when
the GUI is launched (this happens if the CLI window is already running
when the user starts the GUI, or if another copy of the GUI is already
running when the user starts the GUI), a dialog window displays the
following warning message:
The CLI handler is already running.
This may cause conflicts with the LMF.
Are you sure that you want to start the application?
This window also contains yes and no buttons. Selecting yes starts the
application. Selecting no terminates the application.

CLI Format Conventions
The CLI command can be broken down in the following way:
Sverb
Sdevice including device identifier parameters
Sswitch
Soption parameters consisting of:
– keywords
–equals sign (=) between the keyword and the parameter value
–parameter values
Spaces are required between the verb, device, switch, and option
parameters. A hyphen is required between the device and its identifiers.
Following is an example of a CLI command.
measure bbx–<bts_id>–<bbx_id> rssi channel=6 sector=5
Refer to the LMF CLI Commands, R 15.X (68P09251A59) for a
complete explanation of the CLI commands and their use.
Logging into a BTS
Be sure that the correct bts–#.cdf and cbsc–#.cdf file is
used for the BTS. These should be the CDF files that are
provided for the BTS by the CBSC. Failure to use the
correct CDF files can result in wrong results. Failure to
use the correct CDF files to log into a live (traffic
carrying) site can shut down the site.
IMPORTANT
*
Logging into a BTS establishes a communications link between the BTS
and the CDMA LMF. You may be logged into one or more BTS’s at a
time, but only one LMF may be logged into each BTS.
Before attempting to log into the BTS, confirm the CDMA LMF is
properly connected to the BTS (see Figure 3-4). Follow the procedure in
Table 3-8 to log into a BTS.
Prerequisites
Before attempting to login to a BTS, ensure the following have been
completed:
SThe LMF is correctly installed and prepared.
SA bts-nnn folder with the correct CDF and CBSC file exists.
SThe LMF is correctly installed and prepared, and the LMF computer
was connected to the BTS before starting the Windows operating
system and LMF software. If necessary, restart the computer after
connecting it to the BTS (see Table 3-6 and Figure 3-4).

BTS Login from the CLI Environment
Follow the procedures in Table 3-9 to log into a BTS when using the
GUI environment
Table 3-9: BTS CLI Login Procedure
Step Action
1Double click the WinLMF CLI desktop icon (if the LMF CLI environment is not already running).
NOTE
If a BTS was logged into under a GUI session when the CLI environment was started, the CLI session
will be logged into the same BTS, and step 2 is not required.
2At the /wlmf prompt, enter the following command:
login bts–<bts#> host=<host> port=<port>
where:
host = MGLI card IP address (defaults to address last logged into for this BTS or 128.0.0.2 if this is
first login to this BTS).
port = IP port of the TS (defaults to port last logged into for this BTS or 9216 if this is first login to
this BTS)
Logging Out
Logging out of a BTS is accomplished differently for the GUI and the
CLI operating environments.
The GUI and CLI environments use the same connection to
a BTS. If a BTS is logged into in both the GUI and the CLI
environments 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.

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 CSM2 card is required when using the R–GPS. The GPS receiver
(mounted on CSM 1) is used as the primary timing reference and
synchronizes the entire cellular system. CSM 2 provides redundancy (but
does not have a GPS receiver).
The BTS may be equipped with a LORAN–C LFR, HSO, or external 10
MHz Rubidium source which the CSM can use as a secondary timing
reference. In all cases, the CSM monitors and determines what reference
to use at a given time.
For RF–GPS, verify the CSM configured with the GPS
receiver “daughter board” is installed in the frame’s CSM 1
slot before continuing.
IMPORTANT
*
Follow the steps outlined in Table 3-16 to enable the CSMs installed in
the C–CCP shelves.
Table 3-16: Enable CSMs
Step Action
1Click on the target CSM.
From the Device pull down, select Enable.
NOTE
If equipped with two CSMs, enable CSM–2 first
A status report is displayed confirming change in the device(s) status.
Click OK to close the status report window.
NOTE
FAIL may be shown in the status table for enable action. If Waiting For Phase Lock is shown in the
Description field, the CSM changes to the Enabled state after phase lock is achieved.
CSM 1 houses the GPS receiver. The enable sequence can take up to one hour (see below).
* IMPORTANT
The GPS satellite system satellites are not in a geosynchronous orbit and are maintained and operated
by the United States Department of Defense (D.O.D.). The D.O.D. periodically alters satellite orbits;
therefore, satellite trajectories are subject to change. A GPS receiver that is INS contains an “almanac”
that is updated periodically to take these changes into account.
If a GPS receiver has not been updated for a number of weeks, it may take up to an hour for the GPS
receiver “almanac” to be updated.
Once updated, the GPS receiver must track at least four satellites and obtain (hold) a 3–D position fix
for a minimum of 45 seconds before the CSM will come in service. (In some cases, the GPS receiver
needs to track only one satellite, depending on accuracy mode set during the data load).

CSM System Time – GPS & LFR/HSO Verification

Clock Synchronization
Manager System Time
The primary function of the Clock Synchronization Manager (CSM)
boards (slots 1 and 2) is to maintain CDMA system time. The CSM in
slot 1 is the primary timing source while slot 2 provides redundancy.
The CSM2 card (CSM second generation) is required when using the
remote GPS receiver (R–GPS). R–GPS uses a GPS receiver in the
antenna head that has a digital output to the CSM2 card. CSM2 can have
a daughter card as a local GPS receiver to support an RF–GPS signal.
The CSM2 switches between the primary and redundant units (slots 1
and 2) upon failure or command. CDMA Clock Distribution Cards
(CCDs) buffer and distribute even–second reference and 19.6608 MHz
clocks. CCD 1 is married to CSM 1 and CCD 2 is married to CSM 2. A
failure on CSM 1 or CCD 1 cause the system to switch to redundant
CSM 2 and CCD 2.
Each CSM2 board features an ovenized, crystal oscillator that provides
19.6608 MHz clock, even second pulse, and 3 MHz referenced to the
selected synchronization source (see Table 3-19):
SGPS: local/RF–GPS or remote/R–GPS
SLORAN–C Frequency Receiver (LFR) or High Stability Oscillator
(HSO)
SExternal reference oscillator sources
Fault management has the capability of switching between the GPS
synchronization source and the LFR/HSO backup source in the event of
a GPS receiver failure on CSM 1. During normal operation, the CSM 1
board selects GPS as the primary source (see Table 3-19). The source
selection can also be overridden via the LMF or by the system software.
Synchronization between the primary and redundant CSM CCD pairs, as
well as the LFR or HSO back–up to GPS synchronization, increases
reliability.
Low Frequency Receiver/
High Stability Oscillator
The CSM handles the overall configuration and status monitoring
functions of the LFR/HSO. In the event of GPS failure, the LFR/HSO is
capable of maintaining synchronization initially established by the GPS
reference signal.
The LFR requires an active external antenna to receive LORAN RF
signals. Timing pulses are derived from this signal, which is
synchronized to Universal Time Coordinates (UTC) and GPS time. The
LFR can maintain system time indefinately after initial GPS lock.

CSM System Time – GPS & LFR/HSO Verification – continued
Apr 2001 3-33
SCt4812ET BTS Optimization/ATP — CDMA LMF
DRAFT
The HSO is a high stability 10 MHz oscillator with the necessary
interface to the CSMs. The HSO is typically installed in those
geographical areas not covered by the LORAN–C system. Since the
HSO is a free–standing oscillator, system time can only be maintained
for 24 hours after 24 hours of GPS lock.
Upgrades and Expansions: LFR2/HSO2/HSOX
LFR2/HSO2 (second generation cards) both export a timing signal to the
expansion or logical BTS frames. The associated expansion or logical
frames require an HSO–expansion (HSOX) whether the starter frame has
an LFR2 or an HSO2. The HSOX accepts input from the starter frame
and interfaces with the CSM cards in the expansion frame. LFR and
LFR2 use the same source code in source selection (see Table 3-19).
HSO, HSO2, and HSOX use the same source code in source selection
(see Table 3-19).
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.

Connecting Test Equipment to
the BTS
All test equipment is controlled by the LMF via IEEE–488/GPIB bus.
The LMF requires each piece of test equipment to have a factory set
GPIB address. If there is a communications problem between the LMF
and any piece of test equipment, verify that the GPIB addresses have
been set correctly (normally 13 for a power meter and 18 for a CDMA
analyzer).
The following test equipment is required to perform optimization,
calibration and ATP tests:
SLMF
STest set
SDirectional coupler and attenuator
SRF cables and connectors
Refer to Table 3-21 for an overview of connections for test equipment
currently supported by LMF. In addition, see the following figures:
SFigure 3-9 and Figure 3-10 show the test set connections for TX
calibration
SFigure 3-11 and Figure 3-12 show the test set connections for
optimization/ATP tests
Supported Test Sets
Optimization and ATP testing may be performed using one of the
following test sets:
SCyberTest
SAdvantest R3465 and HP–437B or Gigatronics Power Meter
SHewlett–Packard HP 8935
SHewlett–Packard HP 8921 (W/CDMA and PCS Interface (1.9 GHz)
and HP–437B or Gigatronics Power Meter
SSpectrum Analyzer (HP8594E) – optional
SRubidium Standard Timebase – optional
To prevent damage to the test equipment, all TX test
connections must be through the 30 dB directional coupler
for an 800 MHz BTS and the 30 dB directional coupler
plus a 20 dB in-line attenuator for a 1.9 GHz BTS.

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
DRAFT
SCt4812ET BTS Optimization/ATP — CDMA LMF Apr 2001

Background
Proper test equipment setup ensures that the test equipment and
associated test cables do not introduce measurement errors, and that
measurements are correct.
If the test set being used to interface with the BTS has been
calibrated and maintained as a set, this procedure does not
need to be performed. (Test Set includes LMF terminal,
communications test set, additional test equipment,
associated test cables, and adapters.)
NOTE
This procedure must be performed prior to beginning the optimization.
Verify all test equipment (including all associated test cables and
adapters actually used to interface all test equipment and the BTS) has
been calibrated and maintained as a set.
If any piece of test equipment, test cable, or RF adapter,
that makes up the calibrated test equipment set, has been
replaced, re-calibration must be performed. Failure to do so
can introduce measurement errors, resulting in incorrect
measurements and degradation to system performance.
CAUTION
Calibration of the communications test set (or equivalent
test equipment) must be performed at the site before
calibrating the overall test set. Calibrate the test equipment
after it has been allowed to warm–up and stabilize for a
minimum of 60 minutes.
IMPORTANT
*
Purpose
These procedures access the CDMA LMF automated calibration routine
used to determine the path losses of the supported communications
analyzer, power meter, associated test cables, and (if used) antenna
switch that make up the overall calibrated test set. After calibration, the
gain/loss offset values are stored in a test measurement offset file on the
CDMA LMF.

Calibrating Test Equipment
The calibrate test equipment function zeros the power measurement level
of the test equipment item that is to be used for TX calibration and audit.
If both a power meter and an analyzer are connected, only the power
meter is zeroed.
Calibrate Test Equipment from the Util menu list is used to calibrate
test equipment item before being used for testing. The test equipment
must be selected before beginning calibration. Follow the procedure in
Table 3-24 to calibrate the test equipment.

Calibrating Cables
The cable calibration function is used to measure the loss (in dB) for the
TX and RX cables that are to be used for testing. A CDMA analyzer is
used to measure the loss of each cable configuration (TX cable
configuration and RX cable configuration). The cable calibration
consists of the following 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.
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
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.

Introduction
Calibration compensates for normal equipment variations within the
BTS and assures maximum measurement accuracy.
RF Path Bay Level Offset
Calibration
Calibration identifies the accumulated gain in every transmit path
(BBX2 slot) at the BTS site and stores that value in the CAL file. The
BLOs are subsequently downloaded to each BBX2.
Each receive path starts at a BTS RX antenna port and terminates at a
backplane BBX2 slot. Each transmit path starts at a BBX2 backplane
slot, travels through the LPA, and terminates at a BTS TX antenna port.
Calibration identifies the accumulated gain in every transmit path
(BBX2 slot) at the BTS site and stores that value in the CAL file. Each
transmit path starts at a C–CCP shelf backplane BBX2 slot, travels
through the LPA, and ends at a BTS TX antenna port. When the TX path
calibration is performed, the RX path BLO will automatically be set to
the default value.
When to Calibrate BLOs Calibration of BLOs is required after initial BTS installation.
The BLO data of an operational BTS site must be re-calibrated once
each year. Motorola recommends re-calibrating the BLO data for all
associated RF paths after replacing any of the following components or
associated interconnecting RF cabling:
SBBX2 board
SC–CCP shelf
SCIO card
SCIO to LPA backplane RF cable
SLPA backplane
SLPA

TX Path Calibration
The TX Path Calibration assures correct site installation, cabling, and the
first order functionality of all installed equipment. The proper function
of each RF path is verified during calibration. The external test
equipment is used to validate/calibrate the TX paths of the BTS.
Before installing any test equipment directly to any TX
OUT connector you must first verify that there are no
CDMA channels keyed. Have the OMC–R place the sector
assigned to the LPA under test OOS. Failure to do so can
result in serious personal injury and/or equipment damage.
WARNING
Always wear a conductive, high impedance wrist strap
while handling any circuit card/module. If this is not done,
there is a high probability that the card/module could be
damaged by ESD.
CAUTION
At new site installations, to facilitate the complete test of
each CCP shelf (if the shelf is not already fully populated
with 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).

BLO Calibration Data File
During the calibration process, the LMF creates a calibration (BLO) data
file. After calibration has been completed, this offset data must be
downloaded to the BBX2s using the Download BLO function. An
explanation of the file is shown below.
Due to the size of the file, Motorola recommends that you
print out a hard copy of a bts.cal file and refer to it for the
following descriptions.
NOTE
The CAL file is subdivided into sections organized on a per slot basis (a
slot Block).
Slot 1 contains the calibration data for the 12 BBX2 slots. Slot 20
contains the calibration data for the redundant BBX2 (see Table 3-31).
Each BBX2 slot header block contains:
SA creation Date and Time – broken down into separate parameters of
createMonth, createDay, createYear, createHour, and createMin.
SThe number of calibration entries – fixed at 720 entries corresponding
to 360 calibration points of the CAL file including the slot header and
actual calibration data.
SThe calibration data for a BBX2 is organized as a large flat array. The
array is organized by branch, BBX2 slot, and calibration point.
–The first breakdown of the array indicates which branch the
contained calibration points are for. The array covers transmit, main
receive and diversity receive offsets as follows:

SRefer to the hard copy of the file. As you can see, 10 calibration
points per sector are supported for each branch. Two entries are
required for each calibration point.
SThe first value (all odd entries) refer to the CDMA channel

Transmit (TX) Path Calibration
The assigned channel frequency and power level (as measured at the top
of the frame) for transmit calibration is derived from the site CDF file.
For each BBX2, the channel frequency is specified in the ChannelList
CDF file parameter and the power is specified in the SIFPilotPwr
CDF file parameter for the sector associated with the BBX2 (located
under the ParentSECTOR field of the ParentCARRIER CDF file
parameter).
The calibration procedure attempts to adjust the power to within +0.5 dB
of the desired power. The calibration will pass if the error is less than
+1.5 dB.
The TX Bay Level Offset at sites WITHOUT the directional coupler
option, is approximately 42.0 dB ±3.0 dB.
SAt sites WITHOUT RFDS option, BLO is approximately
42.0 dB ±4.0 dB. A typical example would be TX output power
measured at BTS (36.0 dBm) minus the BBX2 TX output level
(approximately –6.0 dBm) would equate to 42 dB BLO.
The TX Bay Level Offset at sites WITH the directional coupler option,
is approximately 41.4 dB ±3.0 dB. TX BLO = Frame Power Output
minus BBX2 output level.
SExample: TX output power measured at RFDS TX coupler
(39.4 dBm) minus the BBX TX output level (approximately
–2.0 dBm) and RFDS directional coupler/cable (approximately
–0.6 dBm) would equate to 41.4 dB BLO.
The LMF Tests menu list items, TX Calibration and All Cal/Audit,
perform the TX BLO Calibration test for a XCVR(s). The All Cal/Audit
menu item performs TX calibration, downloads BLO, and performs TX
audit if the TX calibration passes. All measurements are made through

All Cal/Audit Test
The Tests menu item, All Cal/Audit, performs the TX BLO Calibration
and Audit test for a XCVR(s). All measurements are made through the
appropriate TX output connector using the calibrated TX cable setup.
If the TX calibration portion of the test passed, the BLO
data will automatically be downloaded to the BBX2(s)
before the audit portion of the test is run.
NOTE
Prerequisites
Before running this test, the following should be done:
SCSM–1, GLI2s, BBX2s have correct code and data load.
SPrimary CSM and MGLI2 are INS.
SAll BBXs are OOS_RAM.
STest equipment and test cables are calibrated and connected for TX
BLO calibration.
SLMF is logged into the BTS.
Follow the procedures in Table 3-36 to perform the All Cal/Audit test.
Before installing any test equipment directly to any TX

Create CAL File
The Create Cal File function gets the BLO data from BBXs and
creates/updates the CAL file for the BTS. If a CAL file does not exist a
new one is created. If a CAL file already exists it is updated. After a
BTS has been fully optimized a copy of the CAL file must exist so it can
be transferred to the CBSC. If TX calibration has been successfully
performed for all BBXs and BLO data has been downloaded, a CAL file
will exist. Note the following:
SThe Create Cal File function only applies to selected (highlighted)
BBXs.
Editing the CAL file is not encouraged as this action can
cause interface problems between the BTS and the LMF.
To manually edit the CAL file you must first logout of the
BTS. If you manually edit the CAL file and then use the
Create Cal File function the edited information will be lost.
