Sector Configuration
There are a number of ways to configure the BTS frame. Table 1-3
outlines the basic requirements. When carrier capacity is greater than
two, a 2:1 or 4:1 cavity combiner must be used. For one or two carriers,
bandpass filters or cavity combiners may be used, depending on
sectorization and channel sequencing.

Preliminary Operations: Overview
Introduction
This section first verifies proper frame equipage. This includes verifying
module placement, jumper, and dual in–line package (DIP) switch
settings against the site-specific documentation supplied for each BTS
application. Next, pre-power up and initial power-up procedures are
presented.
Cell Site Types
Sites are configured as Omni 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. For more information on the differences in site types, please
refer to the BTS/Modem Frame Hardware Installation manual.
CDF
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, BBX boards, MCC boards
(per cage), and linear power amplifier assignments are some of the
equipage data included in the CDF.
IMPORTANT
Be sure that the correct bts–#.cdf and cbsc–#.cdf files are
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 cause system errors. Failure to use
the correct CDF files to log into a live (traffic carrying)
site can shut down the site.
Site Equipage Verification
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.
CAUTION
Always wear a conductive, high impedance wrist strap
while handling any circuit card/module to prevent damage
by ESD. After removal, the card/module should be placed
on a conductive surface or back into the anti–static
shipping bag.
Initial Installation of
Boards/Modules
Follow the procedure in Table 2-1 to verify the initial installation of
boards/modules.

Step
Action
Refer to the site documentation and install all boards and modules into the appropriate shelves as
required. Verify they are NOT SEATED at this time.
NOTE
On 800 MHz systems, the Switch Card has a configuration switch that must match the site
configuration (see Figure 2-1).
As the actual site hardware is installed, record the serial number of each module on a “Serial Number
Checklist” in the site logbook.

DC Power Pre-test (BTS Frame)
Before applying any power to the BTS frame, follow the procedure in
Table 2-2 while referring to Figure 2-3 and Figure 2-4 for +27 V
systems or to Figure 2-5 and Figure 2-6 for –48 V systems to verify
there are no shorts in the BTS frame DC distribution system.
Table 2-2: DC Power Pre–test (BTS Frame)
Step
Action
Physically verify that all DC power sources supplying power to the frame are OFF or disabled.
On each frame:
Unseat all circuit boards (except CCD and CIO cards) in the C–CCP shelf and LPA shelves, but
leave them in their associated slots.
Set C–CCP shelf breakers to the OFF position by pulling out power distribution breakers (labeled
C–CCP 1, 2, 3 on the +27 V BTS C–CCP power distribution panel and labeled POWER
1,4,5,2,6,7,3,8,9 on the –48 V C–CCP power distribution panel).
Set LPA breakers to the OFF position by pulling out the LPA breakers (8 breakers, labeled 1A–1B
through 4C–4D – located on the C–CCP power distribution panel in the +27 V BTS or on the
power conversion shelf power distribution panel in the –48 V BTS).
Verify that the resistance from the power (+ or –) feed terminals with respect to the ground terminal on
the top of the frame measures > 500 Ω (see Figure 2-3).
If 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).
Set the C–CCP (POWER) breakers to the ON position by pushing them IN one at a time. Repeat
Step 3 after turning on each breaker.
* IMPORTANT
If the ohmmeter stays at 0 Ω after inserting any board/module, 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.
Insert and lock the DC/DC converter modules for the C–CCP shelf and into their associated slots one
at a time. Repeat Step 3 after inserting each module.
A typical response is that the ohmmeter steadily climbs 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:
STPN4009
– PWR CONV
CDMA RCVR (in +27 V BTS C–CCP shelf)
STPN4045A
– PWR CONV CDMA RCVR (in –48 V BTS C–CCP shelf)
Insert 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.
A typical response is that the ohmmeter steadily climbs in resistance as capacitors charge, stopping
at approximately 500 Ω..

DC Power Pre-test (RFDS)
Before applying power to the RFDS, follow the steps in Table 2-3, while
referring to Figure 2-7, to verify there are no shorts in the RFDS DC
distribution system, backplanes, or modules/boards. As of the date of
this publication, the RFDS is not used with the –48 V BTS.
IMPORTANT
Visual inspection of card placement and equipage for each
frame vs. site documentation must be completed, as
covered in Table 2-1, on page 2-2, before proceeding with
this test.
Table 2-3: DC Power Pre-test (RFDS)
Step
Action
Physically verify that all DC/DC converters supplying the RFDS are OFF or disabled.
Set the input power rocker switch P1 to the OFF position (see Figure 2-7).
Verify the initial resistance from the power (+ or –) feed terminal with respect to ground terminal
measures > 5 kΩ , then slowly begins to increase.
If the initial reading is < 5 kΩ and remains constant, a short exists somewhere in the DC
distribution path supplied by the breaker. Isolate the problem before proceeding.
Set the input power rocker switch P1 to the ON position.
Repeat Step 3.

Initial Power–up Tests
Power-up Procedures
WARNING
Potentially lethal voltage and current levels are routed to
the BTS equipment. This test must be performed with a
second person present, acting in a safety role. Remove all
rings, jewelry, and wrist watches prior to beginning this
test.
DC Input Power
In the tests to follow, power will first be verified at the input to each
BTS frame. After power is verified, cards and modules within the frame
itself will be powered up and verified one at a time.
Before applying any power, verify the correct power feed and return
cables are connected between the power supply breakers and the power
connectors at the top of each BTS frame. Verify correct cable position
referring to Figure 2-3 on page 2-7 for +27 V systems and Figure 2-5 on
page 2-9 for –48 V systems.
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.
IMPORTANT
For positive power applications (+27 V):
The positive power cable is red.
The negative power cable (ground) is black.
For negative power applications (–48 V):
The negative power cable is red or blue.
The positive power cable (ground) is black.
In all cases, the black power cable is at ground potential.
Motorola recommends that the DC input power cable used to connect the
frame to the main DC power source conforms to the guidelines outlined
in Table 2-4.

Step
Action
Physically verify that all DC power sources supplying the frame are OFF or disabled.
On the RFDS (for +27 V systems only), set the input power switch P1 to the OFF position (see
Figure 2-7).
On each frame:
Unseat all circuit boards (except CCD and CIO cards) in the C–CCP shelf and LPA shelves, but
leave them in their associated slots.
Set breakers to the OFF position by pulling out C–CCP and LPA breakers (see Figure 2-3 on
page 2-7 or Figure 2-5 on page 2-9 for breaker panel layout if required).
– C–CCP shelf breakers are labeled CCCP–1, 2, 3 in the +27 V BTS and labeled POWER
1,4,5,2,6,7,3,8,9 in the –48 V BTS.
– LPA breakers are labeled 1A–1B through 4C–4D.
Inspect input cables, verify correct input power polarity via decal on top of frame (+27 Vdc or
–48 Vdc).
Apply power to BTS frames, one at a time, by setting the appropriate breaker in the power supply that
supplies the frame to the ON position.
After power is applied to each frame, use a digital voltmeter to verify power supply output voltages at
the top of each BTS frame are within specifications: +27.0 Vdc or –48 Vdc nominal.

Optimization/Calibration – Introduction
Introduction
This section describes procedures for isolating the BTS from the span
lines, preparing and using the LMF, downloading system operating
software, CSM reference verification/optimization, set up and calibration
of the supported test equipment, transmit/receive path verification, using
the RFDS, and verifying the customer defined alarms and relay contacts
are functioning properly.
IMPORTANT
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.
Optimization Process
After a BTS is physically installed and the preliminary operations
(power up) have been completed, the LMF is used to calibrate and
optimize the BTS. Motorola recommends that the optimization be
accomplished as follows:
1. Download MGLI2–1 with code and data and then enable MGLI2–1.
2. Use the status function and verify that all of the installed devices of
the following types respond with status information: CSM, BBX,
GLI2, 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 the LMF.
3. Download code and data to all devices of the following types:
– CSM
– BBX (may be BBX2 or BBX–1X)
– GLI2 (other than MGLI2–1)
– MCC (may be MCC–8E, MCC24, or MCC–1X)
4. Download the RFDS TSIC (if installed).
5. Verify the operation of the GPS and HSO signals.
6. Enable the following devices (in the order listed):
– Secondary CSM
– Primary CSM
– All MCCs
7. Connect the required test equipment for a full optimization.
8. Select the test equipment.
9. 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
10. 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.
11. If the TX calibration fails, repeat the full optimization for any failed
paths.
12. If the TX calibration fails again, correct the problem that caused the
failure and repeat the full optimization for the failed path.
13. 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.
Cell Site Types
Sites are configured as Omni/Omni or Sector/Sector (TX/RX). Each type
has unique characteristics and must be optimized accordingly.
NOTE
For more information on the differences in site types,
please refer to the applicable BTS/Modem Frame Hardware
Installation and Functional Hardware Description
manuals.
Cell–Site Data File
The Cell–SiteData File (CDF) contains information that defines the BTS
and data used to download files to the devices. A CDF file must be
placed in the applicable BTS folder before the LMF can be used to log
into that BTS. CDF files are normally obtained from the CBSC using a
floppy disk. A file transfer protocol (ftp) method can be used if the LMF
computer has that capability.
The CDF includes the following information:
Download instructions and protocol
Site specific equipage information
C–CCP shelf allocation plan
– BBX 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.

Optimization/Calibration – Introduction – continued
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 BBX output
level required to achieve that power level on any channel/sector can
also be determined.
NOTE
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.
IMPORTANT
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.
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, or the LMF
Help screen, for the procedure.
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 matches the actual site hardware using a CDF conversion
table.
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.

Isolate Span Lines/Connect LMF
Isolate BTS from T1/E1 Spans
IMPORTANT
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!
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 GLI2
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 3-1 and Figure 3-2 as required.
Table 3-1: T1/E1 Span Isolation
Step
Action
From the OMC/CBSC, disable the BTS and place it OOS. Refer to SC OMC–R/CBSC System
Operator Procedures.
– The T1/E1 span 50–pin TELCO cable connected to the BTS frame SPAN I/O board J1 connector
can be removed from both Span I/O boards, if equipped, to isolate the spans.
NOTE
If a third party is used for span connectivity, the third party must be informed before disconnecting the
span line.
* IMPORTANT
Verify that you remove the SPAN cable, not the “MODEM/TELCO” connector.

Step
Action
To gain access to the connectors on the BTS, open the LAN Cable Access door, then pull apart the
Velcro tape covering the BNC “T” connector (see Figure 3-2).
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 connector.
– If there is still no login response, see Table 6-1, Login Failure Troubleshooting Procedures.
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.

Preparing the LMF
Overview
Software and files for installation and updating of the LMF are provided
on CD ROM disks. The following installation items must be available:
LMF Program on CD ROM
LMF Binaries on CD ROM
CDF for each supported BTS (on diskette or available from the
CBSC)
CBSC File for each supported BTS (on diskette or available from the
CBSC)
The following section provides information and instructions for
installing and updating the LMF software and files.
IMPORTANT

Table 3-3: LMF Operating System Installation
Step
Action
Follow the instructions displayed on the Setup screen.
* 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.
Copy CDF Files from CBSC
Before the LMF can execute the optimization/ATP procedures for the
BTS, the correct bts-#.cdf and cbsc-#.cdf files must be
obtained from the CBSC and put in a bts-# folder in the LMF
notebook. This requires copying the CBSC CDF files to a DOS
formatted diskette, and using the diskette to install the CDF file in the
LMF.
Follow the procedure in Table 3-4 to obtain the CDF files from the
CBSC and copy the files to a diskette. For any further information, refer
to the CDMA LMF Operator’s Guide (Motorola part number
68P64114A78) or the LMF Help screen..
NOTE
If the LMF has ftp capability, the ftp method can be used to
copy the CDF 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.

IMPORTANT
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 work
with locally numbered BTS CDF files. Using this file does
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.
Table 3-4: Copying CBSC CDF Files to the LMF
Step
Action
AT THE CBSC:
Login to the CBSC workstation.
Insert a DOS formatted diskette in the workstation drive.
Type eject –q and press the key.
Type mount and press the key.
NOTE
Look for the “floppy/no_name” message on the last line displayed.
If the eject command was previously entered, floppy/no_name will be appended with a
number. Use the explicit floppy/no_name reference displayed when performing step 7.
Change to the directory containing the file by typing cd (ex. cd
bts–248) and pressing .
Type ls to display the list of files in the directory.
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 /floppy/no_name/
(e.g., unix2dos bts–248.cdf /floppy/no_name/bts–248.cdf).
NOTE
Other versions of Unix do not support the unix2dos and dos2unix commands. In these cases,
use the Unix cp (copy) command. The copied files will be difficult to read with a DOS or
Windows text editor because Unix files do not contain line feed characters. Editing copied CDF
files on the LMF computer is, therefore, not recommended.
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/na_name).

Table 3-4: Copying CBSC CDF Files to the LMF
Step
Action
Repeat steps 5 through 7 for each bts–# that must be supported by the LMF.
When all required files have been copied to the diskette, type eject and press the key.
10
Remove the diskette from the CBSC.
AT THE LMF:
11
Start the Windows operating system.
12
Insert the diskette into the LMF.
13
Using Windows Explorer (or equivalent program), create a corresponding bts–# folder in the
wlmf\cdma 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 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 Field
Replaceable Units (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 procedure in Table 3-5 to establish a named HyperTerminal
connection and create a WIndows desktop shortcut for it.
NOTE
There are differences between Windows NT and Windows
98 in the menus and screens for creating a HyperTerminal
connection. In the following procedure, items applicable
to:
– Windows NT will be identified with Win NT
– Windows 98 will be identified with Win 98

Folder Structure Overview
The LMF uses a wlmf folder that contains all of the essential data for
installing and maintaining the BTS. The list that follows outlines the
folder structure for the LMF. Except for the bts–nnn folders, these
folders are created as part of the the LMF installation. Refer to the
CDMA LMF Operator’s Guide for a complete description of the folder
structure.

BTS–nnn folders (A separate folder is
required for each BTS where bts–nnn is the
unique BTS number; for example, bts–163)

Pinging the Processors
For proper operation, the integrity of the Ethernet LAN A and B links
must be be verified. Figure 3-4 represents a typical BTS Ethernet
configuration. The drawing depicts one (of two identical) links, A and B.
Ping is a program that routes request packets to the LAN network
modules to obtain a response from the specified “targeted” BTS.

Follow the procedure in Table 3-6 and refer to Figure 3-5 or Figure 3-6,
as required, to ping each processor (on both LAN A and LAN B) and
verify LAN redundancy is operating correctly.
CAUTION
Always wear a conductive, high impedance wrist strap
while handling any circuit card/module to prevent damage
by ESD.
IMPORTANT
The Ethernet LAN A and B cables must be installed on
each frame/enclosure before performing this test. All other
processor board LAN connections are made via the
backplanes.

Table 3-6: Pinging the Processors
Step
Action
If you have not already done so, connect the LMF to the BTS (see Table 3-2 on page 3-5).
From the Windows desktop, click the Start button and select Run.
In the Open box, type ping and the (for example, ping 128.0.0.2).
NOTE
128.0.0.2 is the default IP address for MGLI–1 in field BTS units. 128.0.0.1 is the default IP address
for MGLI–2.
Click on the OK button.
If the connection is successful, 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 MGLI fails to respond, reset and perform the ping process again. If the MGLI still fails to
respond, typical problems are shorted BNC to inter-frame cabling, open cables, crossed A and B link
cables, missing 50–Ohm terminators, or the MGLI itself.
