Folder Structure Overview
The LMF uses a <x>:\<lmf home directory> folder that contains all of
the essential data for installing and maintaining the BTS. The following
list outlines the folder structure for LMF. Except for the bts-nnn folders,
these folders are created as part of the LMF installation. Refer to the
CDMA LMF Operator’s Guide for a complete description of the folder
structure.
Figure 3-1: LMF Folder Structure

required for each different version; for
example, a folder name 2.8.1.1.1.5.)

unique BTS number; for example, bts-163.)
NOTE The “loads” folder and all the folders below it are not available
from the LMF for Software Release 2.16.1.x. These folders may
be present as as a legacy from previous software versions or
downloaded from the CBSC/OMC-R.

Span Lines - Interface and Isolation
T1/E1 Span Interface
NOTE At active sites, the OMC-R/CBSC must disable the BTS and
place it out of service (OOS). DO NOT remove the span line
cable connectors until the OMC-R/CBSC has disabled the BTS.
Each frame is equipped with one 50-pair punchblock for spans,
customer alarms, remote GPS, and BTS frame alarms. See Figure 3-4
and refer to Table 3-6 for the physical location and punchdown location
information.
Before connecting the LMF computer to the frame LAN, the
OMC-R/CBSC must disable the BTS and place it OOS. This will allow
the LMF to control the BTS, and prevent the CBSC from inadvertently
sending control information to the BTS during LMF-based tests.
Isolate BTS from T1/E1 Spans
Once the OMC-R/CBSC has disabled the BTS, the spans must be
disabled to ensure the LMF will maintain control of the BTS. To disable
the spans, disconnect the BTS-to-CBSC Transcoder span cable
connectors from the Span I/O cards (Figure 3-2).

T1/E1 Span Isolation
Table 3-5 describes the action required for span isolation.
Table 3-5: T1/E1 Span Isolation
Step Action
1Have the OMCR/CBSC place the BTS OOS.
2To disable the span lines, locate the connector for the span or spans which must be disabled and
remove the respective connector from the applicable SCCP cage Span I/O board (Figure 3-2).
Configure Optional Channel Service Units
The M-PATH 537 Channel Service Unit (CSU) module provides
in-band SNMP-managed digital service access to T1 and fractional T1
lines. The M-PATH 437 Channel Service Unit (CSU) module provides
in-band SNMP-managed digital service access to E1 and fractional E1
lines. CSU modules plug into the CSU shelf (see Figure 3-3).
The CSU shelf can support two M-PATH 537 or two M-PATH 437 CSU
modules. A 537 CSU module supports a single T1 span connection. A
437 CSU module supports a single E1 span connection.
Remote M-PATH management is available through SNMP over an
in-band data link on the span line (using a facility data link or
8-64 Kbps of a DS0 channel). The unit at the near end of the
management path can be an SNMP manager or another M-PATH CSU.
Programming of the M-PATH is accomplished through the DCE 9-pin
connector on the front panel of the CSU shelf. Manuals and an MS
Windows programming disk are supplied with each unit.
For more information refer to M-PATH T1 Channel Service Unit User’s
Guide, Kentrox part number 65-77538101 or the ADC M-PATH E1
Channel Service Unit User’s Guide, Kentrox part number 1174139.
Setting the Control Port
Whichever control port is chosen, it must first be configured so the
control port switch settings match the communication parameters being
used by the control device. If using the rear-panel DTE control port, set
the SHELF ADDRESS switch SA5 to “up.” If using the rear-panel DCE
control port, position the SHELF ADDRESS switch down.
For more information, refer to the 2-Slot Universal Shelf Installation
Guide, Kentrox part number 65-78070001, the M-PATH T1 Channel
Service Unit Installation Guide, Kentrox part number 65-77538001, or
the M-PATH E1 Channel Service Unit Installation Guide, Kentrox part
number 1174662, depending on installed equipment.
Plug one of the cables listed below into the Control Port connectors:
Part Number Description of Cable

LMF to BTS Connection
Connect the LMF to the BTS
The LMF computer may be connected to the LAN A or B connector
located behind the frame lower air intake grill. Figure 3-6 below shows
the general location of these connectors. LAN A is considered the
primary LAN.
Table 3-10: Connecting the LMF to the BTS
Step Action
1To gain access to the LAN connectors, open the LAN cable and utility shelf access panel, then pull
apart the hook-and-loop fabric covering the BNC “T” connector (see Figure 3-6). If desired, slide
out the utility shelf for the LMF computer.
2Connect the LMF computer to the LAN A (left-hand) BNC connector via PCMCIA Ethernet Adapter.
NOTE
Xircom Model PE3-10B2 or equivalent can also be used to interface the LMF Ethernet connection to
the BTS frame connected to the PC parallel port, powered by an external AC/DC transformer. In this
case, the BNC cable must not exceed three feet 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.

Using the LMF
Basic LMF Operation
LMF Coverage in This Publication - The LMF application program
supports maintenance of both CDMA and SAS BTSs. All references to
the LMF in this publication are to the CDMA portion of the program.
Operating Environments - The LMF application program allows the
user to work in the two following operating environments which are
accessed using the specified desktop icons:
SGraphical User Interface (GUI) using the WinLMF icon
SCommand Line Interface (CLI) using the WinLMF CDMA 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 - Basic operation of the LMF in either environment
includes performing the following:
SSelecting and deselecting BTS devices
SEnabling devices
SDisabling devices
SResetting devices
SObtaining device status
The following additional basic operation can be performed in a GUI
environment:
SSorting a status report window
For detailed information on performing these and other LMF operations,
refer to the LMF Help function on-line documentation.
NOTE Unless otherwise noted, LMF procedures in this manual are
performed using the GUI environment.
The LMF Display and the BTS
BTS Display - When the LMF is logged into a BTS, a frame tab is
displayed for each RF modem frame (RFMF). For SC4812-series BTSs,
the BTS frames are considered the RFMFs. The frame tab will be
labeled with “CDMA” and the BTS number, a dash, and the frame
number (for example, BTS-812-1 for BTS 812, RFMF 1). If, as with a
single-frame SC4812ET Lite, there is only one frame for the BTS, there
will only be one tab.
CDF Requirements - For the LMF to recognize the devices installed in
the BTS, a BTS CDF file which includes equipage information for all
the devices in the BTS must be located in the applicable <x>:\<lmf
home directory>\cdma\bts-# folder. To provide the necessary channel
assignment data for BTS operation, a CBSC CDF file which includes
channel data for all BTS RFMFs is also required in the folder.

RFDS Display - If an RFDS is included in the CDF file, an RFDS tab
labeled with “RFDS,” a dash and the BTS number-frame number
combination (for example, RFDS-812-1 ) will be displayed.
Logging Into a BTS
Logging into a BTS establishes a communication link between the BTS
and the LMF. An LMF session can be logged into only one BTS at a
time.
Prerequisites
Before attempting to log into a BTS, ensure the following have been
completed:
SThe LMF is correctly installed on the LMF computer.
SA bts-nnn folder with the correct CDF and CBSC files exists.
SThe LMF computer was connected to the BTS before starting the
Windows operating system and the LMF software. If necessary, restart
the computer after connecting it to the BTS in accordance with
Table 3-10 and Figure 3-6.
CAUTION Be sure that the correct bts-#.cdf and cbsc-#.cdf file is used for
the BTS. These should be the CDF files that are provided for the
BTS by the CBSC. Failure to use the correct CDF files can
result in invalid optimization. Failure to use the correct CDF
files to log into a live (traffic-carrying) site can shut down
the site.
BTS Login from the GUI Environment
Follow the procedures in Table 3-11 to log into a BTS when using the
GUI environment.
Table 3-11: BTS GUI Login Procedure
nStep Action
1Start the LMF GUI environment by double-clicking on the WinLMF desktop icon (if the LMF is
not running).
- An LMF window will open and display the LMF build number in the title bar.
NOTE
If a warning similar to the following is displayed, select No, shut down other LMF sessions which
may be running, and start the LMF GUI environment again:
The CLI handler is already running.
This may cause conflicts with the LMF.

Logging Out
Logging out of a BTS is accomplished differently for the GUI and CLI
operating environments.
NOTE The GUI and CLI environments use the same connection to a
BTS. If a BTS is logged into in both the GUI and 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 3-13 to logout of a BTS when using the
GUI environment.

Pinging the BTS
For proper operation, the integrity of the Ethernet LAN A and B links
must be verified. Figure 3-8 represents a typical BTS Ethernet
configuration for an SC4812ET Lite stand-alone or companion frame.
The drawing depicts cabling and termination for both the A and B
LANs.
Ping is a program that sends request data packets to hosts on a network,
in this case GLI modules on the BTS LAN, to obtain a response from the
“target” host specified by an IP address.
Follow the steps in Table 3-16 to ping each processor (on both LAN A
and LAN B) and verify LAN redundancy is working properly.
CAUTION Always wear an approved anti-static wrist strap while handling
any circuit card/module to prevent damage by Electro-Static
Discharge (ESD).

Download the BTS
Overview
Before a BTS can operate, each equipped device must contain device
initialization (ROM) code. ROM code is loaded in all devices during
manufacture, factory repair, or, for software upgrades, from the CBSC
using the DownLoad Manager (DLM). Device application (RAM) code
and data must be downloaded to each equipped device by the user before
the BTS can be made fully functional for the site where it is installed.
ROM Code
Downloading ROM code to BTS devices from the LMF is NOT routine
maintenance or a normal part of the optimization process. It is only
done in unusual situations where the resident ROM code release level in
the device is not compatible with the required release level of the site
operating software and the CBSC can not communicate with the BTS to
perform the download. An example would be a BTS loaded with R16.0
software where a GLI which is factory-loaded with R9.2.x or earlier
ROM code must be installed to replace a malfunctioning GLI.
Before ROM code can be downloaded from the LMF, the correct ROM
code file for each device to be loaded must exist on the LMF computer.
ROM code must be manually selected for download.
NOTE The ROM code file is not available for GLI3s. GLI3s are ROM
code loaded at the factory.
ROM code can be downloaded to a device that is in any state. After the
download is started, the device being downloaded will change to
OOS_ROM (blue). The device will remain OOS_ROM (blue) when the
download is completed. A compatible revision-level RAM code must
then be downloaded to the device. Compatible code loads for ROM and
RAM must be used for the device type to ensure proper performance.
The compatible device code release levels for the BSS software release
being used are listed in the Version Matrix section of the SCt CDMA
Release Notes (supplied on the tape or CD-ROM containing the BSS
software).
Procedures to load ROM code are located in Appendix G.
RAM Code
Before RAM code can be downloaded from the LMF, the correct RAM
code file for each device must exist on the LMF computer. RAM code
can be automatically or manually selected depending on the Device
menu item chosen and where the RAM code file for the device is stored
in the LMF file structure. The RAM code file will be selected
automatically if the file is in the <x>:\<lmf home
directory>\cdma\loads\n.n.n.n\code folder (where n.n.n.n is the
download code version number that matches the “NextLoad” parameter
of the CDF file). The RAM code file in the code folder must have the
correct hardware bin number for the device to be loaded.
RAM code can be downloaded to a device that is in any state. After the
download is started, the device being loaded will change to OOS_ROM
(blue). When the download is completed successfully, the device will
change to OOS_RAM (yellow).

When code is downloaded to an MGLI or GLI, the LMF automatically
also downloads data and then enables the MGLI. When enabled, the
MGLI will change to INS_ACT (bright green). A redundant GLI will
not be automatically enabled and will remain OOS_RAM (yellow).
When the redundant GLI is manually commanded to enable through the
LMF, it will change state to INS_SBY (olive green).
For non-GLI devices, data must be downloaded after RAM code is
downloaded. To download data, the device state must be OOS_RAM
(yellow).
The devices to be loaded with RAM code and data are:
SMaster Group Line Interface (MGLI)
SRedundant GLI
SClock Synchronization Module (CSM) (Only if new revision code
must be loaded)
SMulti Channel CDMA (MCC24E, MCC8E, or MCC-1X) cards
SBroadband Transceiver (BBX2 or BBX-1X) cards
SRFDS Test Subscriber Interface Card (TSIC) or RFDS-1X RFDS
PROCessor (RPROC) card, if RFDS is installed
NOTE The MGLI must be successfully downloaded with RAM code
and data, and in INS_ACT (bright green) status before
downloading any other device. The RAM code download
process for an MGLI automatically downloads data and then
enables the MGLI.
Verify GLI ROM Code Loads
Devices should not be loaded with a RAM code version which is not
compatible with the ROM code with which they are loaded. Before
downloading RAM code and data to the processor cards, follow the
procedure in Table 3-17 to verify the GLI devices are loaded with the
correct ROM code for the software release used by the BSS.
Prerequisite
Identify the correct GLI ROM code load for the software release being
used on the BSS by referring to the Version Matrix section of the SCt
CDMA Release Notes (supplied on the tapes or CD-ROMs containing
the BSS software).

NOTE
The GPS satellite system satellites are not in a geosynchronous orbit and are maintained and operated
by the United States Department of Defense (DOD). The DOD periodically alters satellite orbits;
therefore, satellite trajectories are subject to change. A GPS receiver that is INS contains an ephemeris
(satellite position table) 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 ephemeris 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).
NOTE
SIf two CSMs are installed and the board in slot CSM 1 has enabled, the LMF CSM cage view
should show slot CSM 1 as bright green (INS-ACT) and slot CSM 2 as olive green (INS-SBY)
SIf more than an hour has passed without the board in slot CSM 1 enabling, refer to the CSM System

CSM System Time - GPS & LFR/HSO Verification
Clock Synchronization Manager (CSM) Sub-system Description
Overview - Each BTS CSM sub-system features two CSM boards per
RFMF. The primary function of the CSM cards is to maintain CDMA
system time. GPS is used as the primary timing reference and
synchronizes the entire cellular system. In typical operation, the primary
CSM locks its Digital Phase Locked Loop (DPLL) circuits to GPS
signals. These signals are provided by either an on-board GPS receiver
module (RF-GPS) or a remote GPS receiver (RGPS). RGPS uses a GPS
receiver in the antenna head that has a digital output. The second
generation CSM card (CSM-II) is required when using the RGPS. A
CSM-II card can also be equipped with a local GPS receiver daughter
card to support an RF-GPS signal.
SCCP Shelf CSM Card Slot Assignments - The GPS receiver is
interfaced to the board in SCCP shelf slot CSM 1. This card is the
primary timing source, while the card in slot CSM 2 provides
redundancy. The redundant card, does not have a GPS receiver.
CSM-II Card Type Description - Each CSM-II card features a
temperature-stabilized crystal oscillator that provides 19.6608 MHz
clock, even second pulse, and 3 MHz reference signals to the
synchronization source selected from the following (refer to Table 3-24
for source selection/verification procedures):
SGPS: local/RF-GPS or remote/RGPS
SLORAN-C Low Frequency Receiver (LFR) or High Stability
Oscillator (HSO)
SExternal reference oscillator sources
CDMA Clock Distribution Card (CCD) Description - CCD cards
buffer and distribute even-second reference and 19.6608 MHz clock
signals from the CSM cards. CCD 1 is married to the card in slot CSM
1, and CCD 2 is married to the card in slot CSM 2.
CSM Card Redundancy - The BTS switches between the primary and
redundant units (card slots CSM 1 and CSM 2, respectively) upon failure
or command. A failure in CSM 1 or CCD 1 will cause the system to
switch to the CSM 2-CCD 2 redundant card pair. GPS timing
synchronization is continually maintained between the primary and
redundant CSM-CCD pairs.
Secondary Timing References - The BTS may be equipped with a
LORAN-C Low Frequency Receiver (LFR), a High Stability Oscillator
(HSO), or external 10 MHz Rubidium source which the CSM can use as
a secondary timing reference. Continuous GPS synchronization is
maintained for the LFR or HSO secondary timing references. The CSM
monitors and determines what reference to use at a given time.

PRELIMINARY
3-39
Timing Source Fault Management - 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. During
normal operation, the card in slot CSM 1 selects GPS as the primary
timing source (Table 3-24). The source selection can also be overridden
via the LMF or by the system software.
Low Frequency Receiver/
High Stability Oscillator
General
The CSM and the LFR/HSO - The CSM performs the overall
configuration and status monitoring functions for the LFR/HSO. In the
event of GPS failure, the LFR/HSO is capable of maintaining
synchronization initially established by the GPS reference signal.
LFR - The LFR requires an active external antenna to receive
LORAN-C RF signals. Timing pulses are derived from this signal,
which is synchronized to Universal Time Coordinates (UTC) and GPS
time. The LFR can maintain system time indefinitely after initial GPS
lock.
HSO - The HSO is a high stability 10 MHz oscillator with the necessary
interface to the CSMs. The HSO is typically installed in those
geographical areas not covered by the LORAN-C system. Since the
HSO is a free-standing oscillator, system time can only be maintained
for 24 hours after 24 hours of GPS lock
Upgrades and Expansions: LFR2/HSO2/HSOX
The LFR2 and HSO2 (second generation cards) both can export a timing
signal to other BTS frames located at a site. These secondary frames
require an HSO-expansion (HSOX) module whether the primary frame
has an LFR2 or an HSO2. The HSOX accepts input from the primary
frame and interfaces with the CSM cards in the secondary frames. LFR
and LFR2 use the same source code in source selection (Table 3-24).
HSO, HSO2, and HSOX use the same source code in source selection
(Table 3-24).
NOTE Allow the base site and test equipment to warm up for 60
minutes after any interruption in oscillator power. CSM card
warm-up allows the oscillator oven temperature and oscillator
frequency to stabilize prior to test. Test equipment warm-up
allows the Rubidium standard time base to stabilize in frequency
before any measurements are made.

Equipment Warm-up
NOTE Warm-up BTS equipment for a minimum of 60 minutes prior to
performing the BTS optimization procedure. This assures BTS
stability and contributes to optimization accuracy.
- Time spent running initial or normal power-up,
hardware/firmware audit, and BTS download counts as
warm-up time.
WARNING Before installing any test equipment directly to any BTS TX
OUT connector, verify there are no CDMA channels keyed.
- At active sites, have the OMC-R/CBSC place the antenna
(sector) assigned to the BBX under test OOS. Failure to do
so can result in serious personal injury and/or equipment
damage.

Test Set Calibration
Background
Proper test equipment calibration helps to ensure accurate BTS
optimization and acceptance testing by assuring that the test equipment
and associated cables do not introduce measurement errors.
NOTE If the test equipment set (see the Terms and Abbreviations
section of Chapter 1) being used to optimize or test the BTS has
been calibrated and maintained as a set, this procedure does not
need to be performed.
This procedure must be performed before the optimization. Verify all test
equipment (including all associated cables and adapters actually used to
interconnect test equipment items and the BTS) has been calibrated and
maintained as a set.
CAUTION If any piece of test equipment, test cable, or RF adapter, that
makes up the calibrated test equipment set has been replaced, the
set must be re-calibrated. Failure to do so can introduce
measurement errors, resulting in incorrect measurements and
degradation to system performance. Motorola recommends
repeating cable calibration before testing at each BTS site.
NOTE Calibration of the communications system analyzer (or
equivalent test equipment) must be performed at the site before
calibrating the overall test equipment set. Calibrate the test
equipment after it has been allowed to warm-up and stabilize for
a a minimum of 60 minutes.
Calibration Procedures Included
Automatic
Procedures included in this section use the LMF automated calibration
routine to determine path losses of the supported communications
analyzer, power meter, associated test cables, adapters, and (if used)
antenna switch that make up the overall calibrated test equipment set.
After calibration, the gain/loss offset values are stored in a test
measurement offset file on the LMF computer.
Manual
Agilent E4406A Transmitter Tester - The E4406A does not support
the power level zeroing calibration performed by the LMF. If this
instrument is to be used for Bay Level Offset calibration and calibration
is attempted with the LMF Calibrate Test Equipment function, the
LMF will return a status window failure message stating that zeroing
power is not supported by the E4406A. Refer to the Equipment
Calibration section of Appendix F for instructions on using the
instrument’s self-alignment (calibration) function prior to performing
Bay Level Offset calibration.

Calibrating Cables - Overview
The LMF Cable Calibration function is used to measure the path loss
(in dB) for the TX and RX cables, adapters, directional couplers, and
attenuators that make up the cable configurations used for testing. A
communications system analyzer is used to measure the loss of both the
TX test cable and the RX test cable configurations. LMF cable
calibration consists of the following processes:
1. Measure the loss of a short cable. This is done to compensate for any
measurement error of the communications system analyzer. The
short cable, which is used only for the calibration process, is
connected in series with both the TX and RX test cable
configurations when they are measured. The measured loss of the
short cable is deducted from the measured loss of the TX and RX
test cable configurations to determine the actual loss of the
configurations. This deduction is done so any error in the analyzer
measurement will be adjusted out of both the TX and RX
measurements.

PRELIMINARY

2. Measure the loss of the short cable plus the RX test cable
configuration. The RX test cable configuration normally consists
only of a coax cable with type-N connectors that is long enough to
reach from the BTS RX connector to the test equipment. When the
BTS antenna connectors carry duplexed TX and RX signals, a
directional coupler and, if required by BTS type, an additional
attenuator are also required for the RX test cable configuration.
These additional items must be included in the path loss
measurement.
3. Measure the loss of the short cable plus the TX test cable
configuration. The TX test cable configuration normally consists of
two coax cables with type-N connectors, a directional coupler, a
termination load with sufficient rating to dissipate the BTS output
power, and an additional attenuator, if required by the BTS type. The
total path loss of the TX test configuration must be as required for
the BTS (normally 30 or 50 dB). The Motorola Cybertest analyzer is
different from other communications system analyzers because the
required attenuation/load is built into the test set. Because of this,
the Cybertest TX test configuration consists only of the required
length coax cable.
Calibrating Test Cable Configurations with a Communications System
Analyzer
NOTE LMF cable calibration cannot be accomplished with an
HP8921A analyzer for 1.9 MHz. A different analyzer type or the
signal generator and spectrum analyzer method (Table 3-32 and
Table 3-33) must be used. Cable calibration values must be
manually entered into the LMF cable loss file if the signal
generator and spectrum analyzer method is used. To use the
HP8921A for manual test cable configuration calibration for 800
MHz BTSs, refer to the Manual Cable Calibration section of
Appendix F.
Prerequisites

Setting Cable Loss Values
Cable loss values for TX and RX test cable configurations are normally
set by accomplishing automatic cable calibration using the LMF and the
applicable test equipment. The LMF stores the measured loss values in
the cable loss files. The cable loss values can also be set or changed
manually.
CAUTION If cable calibration was performed without using the LMF, cable
loss values must be manually entered in the LMF database.
Failure to do this will result in inaccurate BTS calibration and
reduced site performance.

PRELIMINARY
3-76
Bay Level Offset Calibration
Purpose of Bay Level Offset Calibration
Bay Level Offset (BLO) calibration is the central activity of the
optimization process. BLO calibration compensates for normal
equipment variations within the BTS RF paths and assures the correct
transmit power is available at the BTS antenna connectors to meet site
performance requirements.
What is BLO Calibration?
Description
BLO calibration is the complete title of what is normally referred to as
“calibration.” Calibration identifies the accumulated gain in every
transmit path at the BTS site. The transmit path BLO values determined
during calibration are stored in the LMF calibration data file, and are
subsequently downloaded to each BBX. When transmit path calibration
is performed, receive path BLO values will automatically be set to the
default value in the LMF calibration file and downloaded.
BTS RF Path Descriptions
Transmit (TX) path - A TX path starts at an SCCP shelf BBX
backplane slot, travels through the CIO card, is routed to the Linear
Power Amplifier (LPA) trunking module for sector phase shifting,
through the LPAs, back through the LPA trunking module for sector
phase selection, through the TX bandpass filter (starter frames) or 2:1
TX combiner (companion frames), through the Transmit & Receive Dual
Directional Coupler (TRDC) or Duplexer Directional Coupler (DRDC),
and ends at the TRDC TX or DRDC antenna connector.
Receive (RX) main path - A main RX path starts at ANTENNAS
connectors 1A, 2A, or 3A and travels through the associated TRDC or
DRDC, the MPC in SCCP cage slot MPC-1, the CIO card, and
terminates at a backplane BBX slot in the SCCP shelf.
Diversity RX path - Diversity RX paths differ for SC4812ET Lite
starter (stand-alone) and companion frames. The following describe each
type of path:
SStarter frame diversity RX path - A starter frame diversity RX path
is the same as a main RX path except that it starts at ANTENNAS
connectors 1B, 2B, or 3B, travels through the associated TRDC or
DRDC, and the MPC card in SCCP cage slot MPC-2 (refer to
Table 1-5).
SCompanion frame diversity RX path - The companion frame main
RX signal is used for the collocated companion frame diversity RX
signal. A companion frame’s diversity RX path starts at ANTENNAS
connectors 1A, 2A, or 3A in the collocated companion frame. It
travels through the associated TRDC or DRDC, the MPC in SCCP
cage slot MPC-1, and the CIO card where it is then routed out of the

frame through the RX expansion out connectors (RX EXPANSION
1A, 2A, or 3A in Figure 1-9 or Figure 1-10). The signal travels
through the inter-frame diversity RX cables, into the RX expansion in
ports (RX EXPANSION 1B, 2B, or 3B in Figure 1-9 or Figure 1-10)
of the companion frame, through the Expansion MPC (EMPC) in
SCCP cage slot MPC-2, the CIO, and terminates at a backplane BBX
slot in the SCCP shelf.
SRFDS sampling paths - Directional couplers for RFDS signal
sampling are integral to the SC4812ET Lite transmit and receive paths
in the DRDCs and TRDCs. Cables connect from these directional
couplers to the RFDS input connectors.
Component Verification During Calibration
TX Path Calibration
TX path calibration supports verification of correct BTS installation, RF
cabling installation and performance, functionality of all equipment
installed in the transmit RF chain, and the proper functioning of each
transmit RF path. External test equipment is used to calibrate and audit
the TX paths of the BTS.
RX Path Calibration
RX path calibration is not required or supported on CDMA BTS
systems. Default RX calibration values are written to the RX calibration
data files during the TX calibration process. RX functionality is verified
during Frame Erasure Rate (FER) testing.
When to Calibrate
Calibration to determine BLO:
1. Is required after initial BTS installation.
2. Must be done once each year for an operational BTS site.
3. Is recommended by Motorola for all associated RF paths after
replacing any of the following components:
- BBX card
- SCCP shelf
- CIO card
- CIO-to-LP A trunking module RF cable
- LPA trunking module
-LPA
- Trunking module-to-TX filter/filter combiner RF cable

BLO Calibration Data File
During the calibration process, the LMF creates a calibration (CAL) data
file where BLO values are stored. After calibration has been completed,
these offset values must be downloaded to the BBXs using the LMF
BLO download function. A detailed description of the file organization
and content is provided in the following paragraphs

NOTE Due to the size of the file, Motorola recommends printing out a
copy of a bts- #.cal file and referring to it for the following
descriptions.
CAL File Organization
The CAL file is subdivided into three sections called “slot Blocks”.
These are:
1. Slot[1] Block which contains the calibration data for the six primary
BBX slots.
2. Slot[20] Block which contains the calibration data for the redundant
BBX (see Table 3-37).
3. Slot[385] Block which contains the calibration data for the RFDS.
BBX Slot Block Parts
BBX slot Blocks are further subdivided into the parts described in the
following:
Slot Block Header - Each BBX slot Block has a header section (slot
header) which contains:
SA creation Date and Time - broken down into separate parameters of
createMonth, createDay, createYear, createHour, and createMin.
SThe number of calibration entries in the file - the numBayLevelPts
parameter. The parameter is fixed at 720 entries for SC4812-series
frames. These 720 entries are combined to define the 360 calibration
points of the CAL file.
SThe slot Block format parameter.
Slot Block Bay Level Calibration Data - Each BBX slot Block has a
Bay Level Calibration data section (BayLevelCal) which is organized as
a large flat array. The array is organized by branch, SCCP cage BBX
slot, and calibration entries. There are several ways to look at the array
contents. Two different views are provided in the following to illustrate
the significant features of BayLevelCal section content and organization:
SThe first view of the array is shown in Table 3-36. This view shows
the three branches of the array, transmit, main receive, and diversity
receive offsets, and the calibration entry ranges which apply to each.

SWhen referring to the CAL file print-out and Table 3-37, it can be
seen that there is one BBX slot per sector with 20 “calibration entries”
per BBX (sector) for each branch. Two calibration entries define a
single “calibration point;” therefore there are ten calibration points in
each branch for each BBX.
- The first entry for a calibration point (all odd entries) identifies the
CDMA channel (frequency) where the BLO is measured. The
second calibration entry (all even entries) is the power set level
(PwrLvlAdj) for that frequency. The valid range for PwrLvlAdj is

from 2500 to 27500 (2500 corresponds to -125 dBm and 27500
corresponds to +125 dBm).
- The ten calibration points for each slot-branch combination must be
stored in order of increasing frequency. If less than ten points
(frequencies) are calibrated, the BLO data for the highest frequency
calibrated is written into the remainder of the ten points for that
slot-branch.
Example:
C[1]=384 (odd cal entry)
C[2]=19102 (even cal entry)
C[3]=777 (odd cal entry)
C[4]=19086 (even cal entry)
C[19]=777 (odd cal entry)
C[20]=19086 (even cal entry)
.
.
.
= 1 “calibration point”
= 1 “calibration point”
= 1 “calibration point”
In the example above, BLO was measured at only two frequencies
(channels 384 and 777) for SCCP slot BBX-1 transmit (Table 3-37).
The BLO data for the highest frequency measured (channel 777) will
be written to the remaining eight transmit calibration points (defined
by entries C[5] through C[20]) for BBX-1.
Slot Block Temperature Compensation - Each BBX slot Block also
has a temperature compensation data section (TempLevelCal) where
power level compensation factors for temperature variations are stored.
CAL File and BLO Data Download
When BLO data is downloaded to the BBXs after calibration, the data is
downloaded to the devices in the order it is stored in the CAL file. TX
calibration data (entries C[1] - C[60]) are sent first. Data for the ten
BBX slot 1 calibration points (entries C[1] - C[20]) are sent initially,
followed by data for the ten BBX slot 2 calibration points (entries C[21]
- C[40]), and so on. The RX calibration data is sent next in BBX slot
sequence, followed by RX Diversity calibration data.
Test Equipment Setup for RF Path Calibration

4! CAUTION
To prevent damage to the test equipment, all transmit (TX) test connections must be via the 30 dB
directional coupler for 800 MHz or via a 30 dB coupler with a 20 dB in-line attenuator for 1900
MHz.
For TX path calibration, connect the test equipment as shown in Figure 3-13, Figure 3-14, or
Figure 3-15, depending on the communications analyzer being used.
Transmit (TX) Path Calibration Description
The assigned channel frequency and desired power level at the frame TX
ports for transmit calibration are derived from the BTS CDF file. Each
BBX at the site is assigned to a sector and carrier. These are specified
respectively in the sector and carrier fields of the ParentCARRIER
parameter in each BBXs CDF file block. The channel frequency and
desired power for the assigned sector are specified respectively in the
ChannelList and SIFPilotPwr parameters of the CDF block for the
CARRIER to which the BBX is assigned.
NOTE Be sure the bts-#.cdf and cbsc-#.cdf files loaded on the LMF
computer are current. The LMF will obtain carrier and channel
information from these files and insert it into the appropriate
CDMA Test Parameter screen. Failure to have the most current
files from the CBSC can result in incorrect channel information
being used to calibrate the BTS and unfavorable affects on BTS
performance. Carrier and channel numbers should only be
entered manually for special test cases or as a last resort.
The calibration process attempts to adjust the measured power to within
+0.5 dB of the desired power. The calibration will pass if the error is less
than +1.5 dB.
The TX BLO for the SC4812ET Lite is approximately 42.0 dB ±5.0 dB.
BLO is the gain in dB between the known power output of the BBX and
the measured power at the TX port. BLO is derived by deducting the
known BBX power output from the power measured at the TX port or
(Measured Power) - (BBX TX Power Output).
Example:
Measured Power (at TX port) = 36.0 dBm
Known BBX TX Power Output = -6.0 dBm
BLO = (36.0) - (-6.0) = 42.0 dB gain

TX Calibration and the LMF
The LMF Tests > TX > TX Calibration... and Tests > All Cal/Audit...
selections perform TX BLO calibration testing for installed BBX(s). The
All Cal/Audit... selection initiates a series of actions to perform TX
calibration, and if calibration is successful, download BLO and perform
TX audit. The TX Calibration... selection performs only TX
calibration. When TX Calibration... is used, BLO download and TX
audit must be performed as separate activities. The CDMA Test
Parameters window which opens when TX Calibration... or All
Cal/Audit... is selected contains several user-selectable features which
are described in the following subsections.
Rate Set Drop-down Pick List
The Rate Set Drop-down Box is enabled if at least one MCC card is
selected for the test. The available options for TX tests are 1 = 9600, and
3 = 9600 1X. Option 3 is only available if 1X cards are selected for the
test. The available transfer rate options for RX tests are 1 = 9600 and
2 = 14400. Option 2 is only available if no 1X cards are selected.
Verify BLO Checkbox
A Verify BLO checkbox is provided and checked by default. After the
actual TX calibration is completed, the BLO derived from the calibration
is compared to a standard, acceptable BLO tolerance for the BTS. In
some installations, additional items may be installed in the transmit path.
The additional change in gain from these items could cause BLO
verification failure and, therefore, failure of the entire calibration. In
these cases, either the Verify BLO checkbox should be unchecked or the
additional path losses should be added into each applicable sector using
the Util > Edit > TX Coupler Loss... function.
Single-Sided BLO Checkbox
An acceptable range of BLO values for each type of BTS is established
to allow for tolerance variations in all the components of the RF chain.
This acceptable range, 42+5 dB for example, is very wide to
accommodate the redundant BBX in the BTS. This is a much wider
tolerance than necessary for the primary BBXs. Primary BBXs normally
will have BLOs in the lower half of the range. Using the example range,
this would be from 37 to 42 dB. Checking the Single-Sided BLO
checkbox should only be done when calibrating primary BBXs because
it will reduce the acceptable BLO value variations to the lower half of
the range. Because this is a much more stringent tolerance, calibrations
run with Single-Sided BLO are more likely to fail and should only be
attempted by an experienced CFE. Never select Single-Sided BLO
when calibrating a redundant BBX.

one MCC.
SPilot (default) - performs calibration using only the pilot channel.
This pattern setting should be used for in-service calibrations, and
requires selection of only a BBX.
SCDFPilot - This pattern setting is for advanced users. It performs
calibration or audit using the CDF value for pilot gain and IS-97 gain
values for all the other channels included in the Standard pattern
setting (paging, synch, and six traffic). Using this pattern setting
requires the selection of both a BBX and at least one MCC.
SCDF - This pattern setting is for advanced users who need to use
CDF gain settings for all channels included in the Standard pattern
setting (pilot, paging, synch, and six traffic). Using this pattern setting
requires the selection of both a BBX and at least one MCC.
Test Pattern Channels and Gain Settings - The CDMA channels and

TX Calibration
WARNING Before installing any test equipment directly to any BTS TX
OUT connector, first verify no CDMA channels are keyed.
Failure to do so can result in serious personal injury and/or
equipment damage.
CAUTION Always wear an approved anti-static wrist strap while handling
any circuit card or module. If this is not done, there is a high
probability that the card or module could be damaged by ESD.
NOTE At new site installations, to facilitate the complete test of each
SCCP shelf (if the shelf is not already fully populated with BBX
boards), move BBX boards from shelves currently not under test
and install them into the empty BBX slots of the shelf currently
being tested to insure that all BBX TX paths are tested.
- This procedure can be bypassed on operational sites that are
due for periodic optimization.
- Prior to testing, view the CDF file to verify the correct
BBX slots are equipped. Edit the file as required to include
BBX slots not currently equipped (per Systems
Engineering documentation).

Calibration Audit Introduction
The BLO calibration audit procedure confirms the successful generation
and storage of the BLO calibration values. The calibration audit
procedure measures the path gain or loss of every BBX transmit path at
the site. In this test, actual system tolerances are used to determine the
success or failure of a test. The same external test equipment set-up
required for TX calibration is used for TX audit.
*RF path verification, BLO calibration, and BLO data
download to BBXs must have been successfully completed
prior to performing the calibration audit.
IMPORTANT
TX Path Audit
Perform the calibration audit of the TX paths of all equipped BBX slots,
per the steps in Table 3-43.
Before installing any test equipment directly to any TX
OUT connector, first verify there are no CDMA BBX
channels keyed. Failure to do so can result in serious
personal injury and/or equipment damage.
WARNING
If a successful All Cal/Audit was completed, this
procedure does not need to be performed, as BLO is
downloaded as part of the All Cal/Audit.
NOTE
TX Audit Test
The Tests menu item, TX Audit, performs the TX BLO Audit test for
BBXs. All measurements are made through the appropriate TX output
connector using the TX calibration setup.

Exception Handling
In the event of a failure, the calibration procedure displays a FAIL
message in the status report window and provides information in the
Description field.
Re-check the test setup and connections and re-run the test. If the tests
fail again, note specifics about the failure, and refer to Chapter 6,
Troubleshooting.
Create CAL File
The LMF 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.
CAUTION 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.

RFDS Set-up and Calibration
RFDS Description
The optional RFDS is used to perform RF tests of the site from the
CBSC or from the LMF. The RFDS contains the following FRUs:
SAntenna Select Unit (ASU)
SFixed Wireless Terminal Interface Card (FWTIC)
SSubscriber Unit Assembly (SUA)
For complete information regarding the RFDS, refer to the CDMA
CDMA RFDS Hardware Installation; 68P64113A93, CDMA RFDS
User’s Guide; 68P64114A51, and the LMF Help function on-line
documentation.
RFDS Parameters
The bts-#.cdf file includes RFDS parameter settings that must match the
installed RFDS equipment. The paragraphs below describe the editable
parameters and their defaults. Table 3-45 explains how to edit the
parameter settings.
SRfdsEquip - valid inputs are 0 through 2.
0 = (default) RFDS is not equipped
1 = Non-Cobra/Patzer box RFDS
2 = Cobra RFDS
STsuEquip - valid inputs are 0 or 1
0 = (default) TSU not equipped
1 = TSU is equipped in the system
SMC1....4 - valid inputs are 0 or 1
0 = (default) Not equipped
1 = Multicouplers equipped in RFDS system
(SC9600 internal RFDS only)
SAsu1/2Equip - valid inputs are 0 or 1
0 = (default) Not equipped
1 = Equipped
STestOrigDN - valid inputs are ’’’ (default) or a numerical string up to
15 characters. (This is the phone number the RFDS dials when
originating a call. A dummy number needs to be set up by the switch,
and is to be used in this field.)
NOTE Any text editor may be used to open the bts-#.cdf file to verify,
view, or modify data. Because the bts-#.cdf file is generated on
a Unix system, a more sophisticated editor, such as MicroSoft

RFDS Calibration
The RFDS Calibration option is used to calibrate the RFDS TX and RX
paths.
TX Path Calibration - For a TX antenna path calibration the BTS
XCVR is keyed at a pre-determined power level and the BTS power
output level is measured by the RFDS. The power level is then measured
at the TX antenna directional coupler by the power measuring test
equipment item being used (power meter or analyzer). The difference
(offset) between the power level at the RFDS and the power level at the
TX antenna directional coupler is used as the TX RFDS calibration
offset value.
RX Path Calibration - For an RX antenna path calibration the RFDS is
keyed at a pre-determined power level and the power input level is
measured by the BTS BBX. A CDMA signal at the same power level
measured by the BTS BBX is then injected at the RX antenna directional
coupler by the communications system analyzer. The difference (offset)
between the RFDS-keyed power level and power level measured at the
BTS BBX is the RFDS RX calibration offset value.
RFDS calibration and the CAL file - The TX and RX RFDS
calibration offset values are written to the CAL file in the slot[385]
Block.
TSIC channel frequency - For each RFDS TSIC, the channel
frequency is determined at the lower third and upper third of the
appropriate band using the frequencies listed in Table 3-50.
Table 3-50: RFDS TSIC Calibration Channel Frequencies
System Channel Calibration Points
800 MHz (A and B) 341 and 682
1.9 GHz 408 and 791
Before installing any test equipment directly to any TX
OUT connector, verify that there are no CDMA channels
keyed. Failure to do so can result in serious personal injury
and/or equipment damage.

Battery Over Temperature Alarm (Optional)
CAUTION Use special care to avoid damaging insulation on cables, or
damaging battery cases when using a heat gun.
Table 3-62 gives instructions on testing the battery over-temperature
alarm system.
Table 3-62: Battery Over-Temperature Alarm
Step Action
1Use a low-powered heat gun to gently heat the battery over-temperature sensor (see location in
Figure 3-24).
! CAUTION
To avoid damaging the cable insulation, do not hold the hot air gun closer than three (3) inches from
the sensor.
2NOTE
When the over-temperature alarm point is reached, an audible click will sound as DC PDA relay K1
contacts engage and relay K2 contacts disengage (make-before-break operation).
When the sensor is heated to approximately 51° C, a battery over-temperature alarm is generated with
the following indications.
- On the MAP, the CHARGE DISABLE LED (red) should light and the MAIN CONN. ENABLE
LED (green) should extinguish.
- The LMF should display an alarm condition as BTS Relay #22 contacts.
3Switch the hot air gun to cool. Cool the sensor until the K1 and K2 contacts return to normal position
(K1 open and K2 closed). The following indications that alarms have cleared should occur:
- On the MAP, the CHARGE DISABLE LED (red) should extinguish and the MAIN CONN.
ENABLE (green) LED should light.
- The alarm reported on LMF will clear

Rectifier Over Temperature Alarm
Table 3-63 gives instructions on testing the rectifier over-temperature
alarm system.
CAUTION Do not attempt to remove the MAP from the front of the frame
to perform the following procedure, even if the frame is equipped
with a MAP cable tray. MAP removal from the front requires
complete site shut-down to avoid accidently shorting 27 Vdc to
ground during the removal process.
Table 3-63: Rectifier Over-Temperature Alarm
Step Action
1Remove the 14 tamper-resistant TORX fasteners securing the rear access panel to the rear of the
frame (Figure 2-1), and remove the rear access panel.
NOTE
Panel fastener type can be either T-27 button head or T-30 pan head.
2Looking up through the frame rear access opening, locate the rear of the MAP.
3Remove the jumper plug from connector J8 on the rear panel of the MAP (Figure 3-25). The
following conditions should occur:
- Contacts on K1 and K2 change states (K1 now closed and K2 open).
- The LMF reports an alarm condition as BTS Relay #26 contacts.
4Reinstall the jumper plug in connector J8, and verify that all alarm conditions have cleared.
5Reinstall the frame rear access panel, securing it with the 14 tamper-resistant TORX fasteners
removed in step 1.
