CDMA LMF Product Description
The Code Division Multiple Access (CDMA) LMF is a graphical user
interface (GUI) based LMF. This product is specifically designed to
provide cellular communications field personnel the vehicle to support
the following CDMA BTS operations:
The LMF also provides Command Line Interface (CLI) capability.
Activate the CLI by clicking on a shortcut icon on the desktop. The CLI
cannot be launched from the GUI, only from the desktop icon.
Online Help
Task oriented online help is available in the LMF by clicking on Help
from the menu bar.
Why Optimize?
What Is Optimization?
Proper optimization and calibration assures:
Accurate downlink RF power levels are transmitted from the site.
Accurate uplink signal strength determinations are made by the site.
Optimization compensates for the site-specific cabling and normal
equipment variations. Cables that interconnect the BTS and Duplexer
assemblies (if used), for example, are cut and installed at the time of the
BTS frame installation at the site. Site optimization guarantees that the
combined losses of the new cables and the gain/loss characteristics and
built-in tolerances of each BTS frame do not accumulate, causing
improper site operation.
Optimization identifies the accumulated loss (or gain) for all receive and
transmit paths at the BTS site, and stores that value in a database.
The RX path starts at the ancillary equipment frame RFDS RX
directional coupler antenna feedline port, through the RX input port
on the rear of the frame, through the DDRCs, Multicoupler Preselector
Card (MPC), and additional splitter circuitry, ending at a CDMA
Channel Processor (C–CCP) backplane Broad Band Transceiver
(BBX) slot in the C–CCP shelf.
A transmit path starts at the BBX, through the C–CCP backplane slot,
travels through the LPA/Combiner TX Filter and ends at the rear of
the input/output (I/O) Panel. If the RFDS option is added, then the
TX path continues and ends at the top of the RFDS TX directional
coupler antenna feedline port installed in the ancillary equipment
frame.

Optimization Overview– continued
These values are factored in by the BTS equipment internally, leaving
only site specific antenna feed line loss and antenna gain characteristics
to be factored in by the CFE when determining site Effective Radiated
Power (ERP) output power requirements.
Each C–CCP shelf BBX board is optimized to a specific RX and TX
antenna port. (One BBX board acts in a redundant capacity for BBXs
1–12, and is optimized to all antenna ports). A single value is generated
for each path, thereby eliminating the accumulation of error that would
occur from individually measuring and summing the gain and loss of
each element in the path.
When to Optimize
New Installations
After the initial site installation, the BTS must be prepared for operation.
This preparation includes verifying hardware installation, initial power
up, and GPS verification. Basic alarm tests are also addressed.
A calibration audit of all RF transmit paths is performed to verify factory
calibration.
1
A series of ATP CDMA verification tests are covered using the actual
equipment set up. An ATP is also required before the site can be placed
in service.
Site Expansion
Optimization is also required after expansion of a site.
Periodic Optimization
Periodic optimization of a site may also be required, depending on the
requirements of the overall system.
Repaired Sites
Verify repair(s) made to the BTS by consulting an Optimization/ATP
Test Matrix table. This table outlines the specific tests that must be
performed anytime a BTS subassembly or RF cable associated with it is
replaced.

Required Test Equipment
To ensure consistent, reliable, and repeatable optimization test results,
test equipment meeting the following technical criteria should be used to
optimize the BTS equipment. You can, of course, substitute test
equipment with other test equipment models supported by the LMF
meeting the same technical specifications.
NOTE
During manual testing, you can substitute test equipment
with other test equipment models not supported by the
LMF, but those models must meet the same technical
specifications.
The customer has the responsibility of accounting for any measurement
variances and/or additional losses/inaccuracies that can be introduced
as a result of these substitutions. Before beginning optimization or
troubleshooting, make sure that the test equipment needed is on hand
and operating properly.
Test Equipment Calibration
Test Cable Calibration
Equipment Warm–up
Optimum system performance and capacity depend on regular equipment
service, calibration, and characterization prior to BTS optimization.
Follow the original equipment manufacturer (OEM) recommended
maintenance and calibration schedules closely.
Equipment test cables are very important in optimization. Motorola
recommends that the cable calibration be run at every BTS with the test
cables attached. This method compensates for test cable insertion loss
within the test equipment itself. No other allowance for test cable
insertion loss needs to be made during the performance of tests.
Another method is to account for the loss by entering it into the LMF
during the optimization procedure. This method requires accurate test
cable characterization in a shop. The cable should be tagged with the
characterization information prior to field optimization.
After arriving at the a site, the test equipment should be plugged in and
turned on to allow warm up and stabilization to occur for as long as
possible. The following pieces of test equipment must be warmed–up for
a minimum of 60 minutes prior to using for BTS optimization or RFDS
calibration procedures.

BTS Equipment Identification
Equipment Overview
The SC 4812ET BTS consists of an RF Cabinet that is an outdoor,
weatherized version of the SC 4812T. The RF cabinet is powered by
27 Vdc and each cabinet has the capability to support up to 4 carriers (at
3 sector) or 2 carriers (at 6 sector).
The RF Cabinet houses the fan modules, C–CCP, LPA modules, LPA
trunking backplane, Bandpass 2:1 & 4:1 Combiners, Duplexer/Receive
Filter/Directional Couplers (DRDC) and a DC Power distribution
assembly. The Power Cabinet (PC) provides +27 Vdc distribution and
battery backup for the SC 4812ET. The Power Cabinet houses batteries,
battery heaters, rectifiers, an AC Load Center (ACLC), a power
distribution assembly, and two duplexed GFCI convenience outlets.
Logical BTS
A logical BTS can consist of up to four SC 4812ET frames. When the
LMF is connected to frame 1 of a logical BTS, you can access all
devices in all of the frames that make up the logical BTS. A logical BTS
CDF file that includes equippage information for all of the logical BTS
frames and their devices is required. A Centralized Base Station
Controller (CBSC) file that includes channel data for all of the logical
BTS fames is also required.
1
The first frame of a logical BTS has a –1 suffix (e.g., BTS–812–1) and
other frames of the logical BTS are numbered with suffixes, –101, –201,
and –301 (e. g. BTS–812–201). When you log 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 separate FRAME
tab for each frame (e.g. FRAME–438–1, FRAME–438–101, and
FRAME–438–202 for a BTS–438 that has all three frames). If an
RFDS is included in the CDF file, an RFDS tab (e.g., RFDS–438–1)
will be displayed.
Actions (e.g., ATP tests) can be initiated for selected devices in one or
more frames of a logical BTS. Refer to the Select devices help screen
for information on how to select devices.
C–CCP Shelf Card/Module Device ID Numbers
All cards/modules/boards in the frames at a single site, assigned to a
single BTS number, are also identified with unique Device ID numbers
dependent upon the Frame ID number in which they are located. Refer to
Table 1-3 and Table 1-4 for specific C–CCP Shelf Device ID numbers.

settings against the site-specific documentation supplied for each BTS
application. Next, pre-power up and initial power-up procedures are
presented.
Sites are configured as with a maximum of 4 carriers, 3–sectored with a
maximum of 4 carriers, and 6–sectored with a maximum of 2 carriers.
Each type has unique characteristics and must be optimized accordingly.
The Cell-site Data File (CDF) contains site type and equipage data
information and passes it directly to the LMF during optimization. The
number of modem frames, C–CCP shelves, BBX2 and
MCC24E/MCC8E boards (per cage), and linear power amplifier
assignments are some of the equipage data included in the CDF.
Review the site documentation. Match the site engineering equipage data
to the actual boards and modules shipped to the site. Physically inspect
and verify the equipment provided for the BTS or Modem frame and
ancillary equipment frame.

Battery Charge Test
(Connected Batteries)
2
Table 2-8: Battery Charge Test (Connected Batteries)
StepAction
1Close the battery compartment breakers for connected batteries ONLY. This process should be
completed quickly to avoid individual battery strings with excess charge current
Table 2-8 lists the step–by–step instructions for testing the batteries.
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.

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:
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.
Download MGLI2–1 with code and data and then enable MGLI2–1.
Use 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.
Download code and data to all devices of the following types:
– CSM2
– BBX
– GLI2 (other than MGLI2–1)
– MCC
3
Apr 2001
Download the RFDS TSIC (if installed).
Verify the operation of the GPS and HSO signals.
Enable the following devices (in the order listed):
Connect the required test equipment for a full optimization.
Select the test equipment.
Calibrate 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
Select all of the BBXs and all of the MCCs and use the full
optimization function. The full optimization function performs TX
calibration, BLO download, TX audit, all TX tests, and all RX tests
for all selected devices.
If the TX calibration fails, repeat the full optimization for any failed
paths.
If the TX calibration fails again, correct the problem that caused the
failure and repeat the full optimization for the failed path.

Cell–site Types
Cell–site Data File
If 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.
Sites are configured as Omni/Omni or Sector/Sector (TX/RX). Each type
has unique characteristics and must be optimized accordingly.
The CDF includes the following information:

Site specific equipage information
C–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

how the paging, synchronization, traffic, and access channel
elements (and associated gain values) are assigned among the (up to
12) MCCs in the shelf.
CSM equipage including redundancy
Effective Rated Power (ERP) table for all TX channels to antennas
respectively. Motorola System Engineering specifies the ERP of a
transmit antenna based on site geography, antenna placement, and
government regulations. Working from this ERP requirement, 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.

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.
IMPORTANT
Site Equipage Verification
*
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.
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.
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 alive (traffic carrying) site can shut down the site.
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.

Unit
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.
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).
– 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.
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.

Connect the LMF to the LAN A BNC connector via PCMCIA Ethernet Adapter with an unshielded
twisted–pair (UTP) Adapter and 10BaseT/10Base2 converter (powered by an external AC/DC
transformer). If there is no login response, connect the LMF to the LAN B BNC connector. If there is
still no login response, see Table 6-1, Login Failure Troubleshooting Procedure.
NOTE
– Xircom Model PE3–10B2 or equivalent can also be used to interface the LMF Ethernet
connection to the frame connected to the PC parallel port, powered by an external AC/DC
transformer. In this case, the BNC cable must not exceed 91 cm (3 ft) in length.
* IMPORTANT
The LAN shield is isolated from chassis ground. The LAN shield (exposed portion of BNC connector)
must not touch the chassis during optimization.

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.
CAUTION
Always wear a conductive, high impedance wrist strap
while handling any circuit card/module to prevent damage
by ESD.

StepAction
1From the Windows desktop, click the Start button and select Run.
2In the Open box, type ping and the GLI2 IP address (for example, ping 128.0.0.2).
NOTE
128.0.0.2 is the default IP address for the GLI2 in field BTS units.
3Click on the OK button.
4If the targeted module responds, text similar to the following is displayed:
Reply from 128 128.0.0.2: bytes=32 time=3ms TTL=255
If there is no response the following is displayed:
Request timed out
If the GLI2 fails to respond, it should be reset and re–pinged. If it still fails to respond, typical
problems are shorted BNC to inter-frame cabling, open cables, crossed A and B link cables, or the
GLI2 itself.

Using CDMA LMF
Basic LMF Operation
NOTE
The terms “CDMA LMF” and “WinLMF” are
interchangeable
Basic LMF Command Line
Interface (CLI) Operation
The CDMA LMF allows the user to work in the two following operating
environments which are accessed using the specified desktop icon:
Graphical User Interface (GUI) using the WinLMF icon
Command 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:
Selecting and deselecting BTS devices
Enabling devices
Disabling devices
Resetting devices
Obtaining device status
Sorting a status report window
For detailed information on performing these and other LMF operations,
refer to the CDMA LMF Operator’s Guide, 68P64114A78.

Apr 2001
.
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:
– 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.
IMPORTANT
*
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.
3-22
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:
The LMF is correctly installed and prepared.
A bts-nnn folder with the correct CDF and CBSC file exists.
The 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).

There may be instances where the BTS initiates a log out due to a system error (i.e., a device
failure).
If the MGLI is OOS_ROM (blue), it will have to be downloaded with code before other devices can
be seen.
If the MGLI is OOS–RAM (yellow), it must be enabled before other installed devices can be seen.

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–
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
<bts#> host=<host> port=<port>
Logging out of a BTS is accomplished differently for the GUI and the
CLI operating environments.
IMPORTANT
*
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.
Logging Out of a BTS from the GUI Environment
Follow the procedure in Table 3-10 to logout of a BTS when using the
GUI environment.
