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 that are accessed using the specified
Desktop Icons.:
– Graphical User Interface (GUI) using the WinLMF Icon
– Command 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 tasks.:
S Selecting and deselecting BTS Devices
S Enabling Devices
S Disabling Devices
S Resetting Devices
S Obtaining Device Status
The following additional Basic Operation can be performed in a GUI
Environment:
S Sorting 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
BTS Frame. The Frame Tab is labeled with “CDMA” and the BTS
Number, a Dash, and the Frame Number (for example, BTS–812–1 for
BTS 812, RF Modem Frame 1). If there is only one frame for the BTS,
there will only be one Frame Tab..

CDF/NECF Requirements
For the LMF to recognize the devices installed in the BTS, a BTS
CDF/NECF File that includes Equipage Information for all the devices
in the BTS must be located in the applicable :\\cdma\bts–# folder. To provide the necessary Channel
Assignment Data for BTS Operation, a CBSC CDF File that includes
Channel Data for all BTS RF Modem Frames is also required in the
folder..
RFDS Display
If an RFDS is included in the CDF/NECF File, an RFDS Tab labeled
with “RFDS,” a Dash, and the BTS Number–Frame Number
Combination (for example, RFDS–812–1) is displayed..

Packet Mode Commands Screen
Figure 3-7 depicts three of the available Packet Mode Commands.
Normally the GLI3 has Self-Managed Network Elements (NEs) Control
of all cards as shown in Figure 3-6 by an “(X)”. In that state, the LMF
may only status a single card.
In order to download code or test a card, the LMF must request
Self-Managed Network Elements (NEs) Control of the card by using the
shown Pull–down Menu. It also uses this menu to release control of the
card back to the GLI3.
The GLI3 also assumes control of the cards after the LMF logs out of the
BTS. The Packet Mode GLI3 normally is loaded with a Tape Release
and NECB and NECJ Files that point to a Tape Release stored on the
GLI3. When the GLI3 has control of a card it will maintain that card
with the code on that Tape Release.

Command Line Interface
Overview
The LMF also provides Command Line Interface (CLI) capability.
Activate the CLI by clicking on a Shortcut Icon on the Desktop. The CLI
can not be launched from the GUI, only from the Desktop Icon.
Both the GUI and the CLI use a program known as the Handler. Only
one Handler can be running at one time. 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:
S Verb
S Device including Device Identifier Parameters
S Switch
S Option Parameters consisting of:
– Keywords
– Equals Sign (=) between the Keyword and the Parameter Value
– Parameter Values
Spaces are required between the verb, device, switch, and option
parameters. A hyphen is required between the device and its identifiers.
Following is an example of a CLI Command.
measure bbx–– rssi channel=6–Sector=5
Refer to the LMF CDMA CLI Reference (68P09262A25) for a complete
explanation of the CLI Commands and their usage.
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 that the following tasks have
been completed:
S The LMF Program is correctly installed on the LMF Computer.
S A bts-nnn Folder with the correct CDF/NECF and CBSC Files is
present.
S The LMF Computer was connected to the BTS before starting the
Windows Operating System and the LMF Software. If necessary,
restart the computer after connecting it to the BTS in accordance with
Table 3-6 and Figure 3-3.
CAUTION
Ensure that the correct bts–#.cdf/necf and cbsc–#.CDF
Files are used for the BTS. These should be the

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.
– If you must download ROM Code, the procedures are located in
Appendix G.
Before ROM Code can be downloaded from the LMF, the correct ROM
Code File for each device to be loaded must be present 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 changes to
OOS_ROM (blue). The device will remain OOS_ROM (blue) when the
download is completed.
A compatible Revision Level RAM Code must then be downloaded to
the device. Compatible Code Loads for ROM and RAM must be used
for the device type to ensure proper performance. The compatible Device
Code Release Levels for the BSS Software Release being used are listed
in the Version Matrix section of the SCt CDMA Release Notes
(supplied on the tape or CD–ROM containing the BSS Software).
RAM Code
Before RAM Code can be downloaded from the LMF, the correct RAM
Code File for each device must be present 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.

Download the BTS
– continued
The RAM Code File will be selected automatically if the file is in the
:\\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 changes to OOS_ROM
(blue). When the download is completed successfully, the device
changes to OOS_RAM (yellow).
When code is downloaded to an MGLI or GLI, the LMF also
automatically downloads data and then enables the MGLI. When
enabled, the MGLI changes to INS_ACTIVE (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 changes state to INS_STANDBY (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:

Selecting CSM Clock Source
and Enabling CSM Cards
CSM Cards must be enabled prior to enabling the MCC Cards.
Procedures in the following two sub-sections cover the actions to
accomplish this. For additional information on the CSM Subsystem, see
“Clock Synchronization Manager (CSM) Subsystem Description” in the
CSM System Time – GPS and HSO Verification section of this chapter.
GPS Satellite System
The GPS Satellite System Satellites are maintained and operated by the
United States Department of Defense (DOD). The DOD periodically
alters satellite orbits; they are not in geo–synchronous orbits. Therefore,
satellite trajectories are subject to change.
A GPS Receiver that is in service (INS) contains an “Almanac” that is
updated periodically to take these changes into account.
– If a GPS Receiver has not been updated for a number of weeks, it
may take up to an hour for the GPS Receiver “Almanac” to be
updated.
– Once updated, the GPS Receiver must track at least four satellites
and obtain (hold) a 3–D position fix for a minimum of 45 seconds
before the CSM will come in service. In some cases, the GPS
Receiver needs to track only one satellite, depending on Accuracy
Mode set during the Data Load.
Select CSM Clock Source
A CSM can have three different Clock Sources. The Select CSM Source
Function can be used to select the Clock Source for each of the three
inputs. This function is only used if the Clock Source for a CSM needs
to be changed. The Clock Source Function provides the following Clock
Source Options.

CSM System Time – GPS and HSO Verification
Clock Synchronization
Manager (CSM) Subsystem
Description
Overview
Each BTS CSM Subsystem features two CSM Cards per RF Modem
Frame. 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 Cage CSM Card Slot Assignments
The GPS Receiver is interfaced to the CSM Card in SCCP Cage Slot
CSM 1. This card is the Primary Timing Source, while the CSM 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 list.
– Refer to Table 3-24 for Source Selection/Verification Procedures..
S GPS: Local/RF–GPS or Remote/RGPS
S High Stability Oscillator (HSO)
S External 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 CSM
1 Card in the CSM 1 Slot, and CCD 2 is married to the CSM 2 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..

CSM System Time – GPS and HSO Verification
– continued
Secondary Timing References
The BTS may be equipped with a High Stability Oscillator (HSO), or
External 10 MHz Rubidium Source that the CSM can use as a Secondary
Timing Reference. Continuous GPS Synchronization is maintained for
the HSO Secondary Timing References. The CSM monitors and
determines what reference to use at a given time..
Timing Source Fault Management
Fault Management has the capability of switching between the GPS
Synchronization Source and the HSO Back–up Source in the event of a
GPS Receiver failure. During normal operation, the CSM Card in the
CSM 1 Slot 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..

High Stability Oscillator (HSO)
The CSM and the HSO
The CSM performs the overall Configuration and Status Monitoring
Functions for the HSO. In the event of GPS failure, the HSO is capable
of maintaining Synchronization initially established by the GPS
Reference Signal..
HSO
The HSO is a High Stability 10 MHz oscillator with the necessary
interface to the CSM Cards. Since the HSO is a free–standing oscillator,
System Time can only be maintained for 24 hours..
Upgrades and Expansions: HSO2/HSOX
The HSO2 (second generation card) exports a Timing Signal to other
BTS Frames located at a site. These Expansion Frames require an HSO
Expansion (HSOX) Card.
The HSOX accepts input from the Starter Frame and interfaces with the
CSM Cards in the Expansion Frames. HSO, HSO2, and HSOX use the
same Source Code in Source Selection (Table 3-24).
NOTE
Allow the BTS and Test Equipment to warm–up for 60
minutes after any interruption in Oscillator Power.
– CSM 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
To assure BTS stability and contribute to Optimization
accuracy of the BTS, warm-up the BTS Test Equipment
prior to performing the BTS Optimization Procedure as
follows:
– Agilent E7495A for a minimum of 30 minutes
– All other Test Sets for a minimum of 60 minutes
Time spent running initial or normal Power-up, Hardware/
Firmware Audit, and BTS Download counts as Warm-up
Time.
WARNING
Before installing any Test Equipment directly to any BTS
TX OUT Connector, verify that there are no CDMA
Channels keyed.
– At active sites, have the OMC-R/CBSC place the
antenna (sector) assigned to the BBX under test to out
of service (OOS). Failure to do so can result in
serious personal injury and/or equipment damage.

Test Equipment GPIB Address
Settings
All Test Equipment is controlled by the LMF through an
IEEE–488/GPIB Bus. To communicate on the Bus, each piece of Test
Equipment must have a GPIB Address Set that the LMF will recognize.
The Standard Address Settings used by the LMF for the various types of
Test Equipment Items are as follows:
S Signal Generator Address: 1
S Power Meter Address: 13
S Communications System Analyzer Address: 18
Using the procedures included in the Verifying and Setting GPIB
Addresses section of Appendix F, verify and, if necessary, change the
GPIB Address of each piece of employed Test Equipment to match the
applicable addresses above
Supported Test Equipment
CAUTION
To prevent damage to the Test Equipment, all Transmit
(TX) Test Connections must be through a 30 dB
Directional Coupler plus a 20dB In-line Attenuator for
both the 800 MHz and 1.9 GHz BTSs.

Equipment Warm-up
NOTE
To assure BTS stability and contribute to Optimization
accuracy of the BTS, warm-up the BTS Test Equipment
prior to performing the BTS Optimization Procedure as
follows:
– Agilent E7495A for a minimum of 30 minutes
– All other Test Sets for a minimum of 60 minutes
Time spent running initial or normal Power-up, Hardware/
Firmware Audit, and BTS Download counts as Warm-up
Time.
WARNING
Before installing any Test Equipment directly to any BTS
TX OUT Connector, verify that there are no CDMA
Channels keyed.
– At active sites, have the OMC-R/CBSC place the
antenna (sector) assigned to the BBX under test to out
of service (OOS). Failure to do so can result in
serious personal injury and/or equipment damage.
Automatic Cable Calibration
Set–up
Figure 3-27 and Figure 3-28 show the Cable Calibration Set–up for the
Test Sets supported by the LMF. The left side of the diagram depicts the
location of the Input and Output Connectors of each Test Equipment
Item, and the right side details the connections for each test. Table 3-32
provides a procedure for performing Automatic Cable Calibration.
Manual Cable Calibration
If Manual Cable Calibration is required, refer to the procedures in
Appendix F.

Test Set Calibration
Test Equipment 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 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 prior to beginning the Optimization.
Verify that 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.
Automatic Calibration
Procedure
Procedures included in this section use the LMF Automated Calibration
Procedure 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.

LMF Cables Calibration
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 Signal Loss of
both the TX Test Cable and the RX Test Cable Configurations. The LMF
Cable Calibration consists of the following processes:
Measure the Signal Loss in a Short Cable
This measurement is done to compensate for any Measurement Error in
the Communications System Analyzer. The Short Test 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 Signal Loss in the Short Test Cable is deducted from the
measured Signal Loss of the TX and RX Test Cable Configurations to
determine the actual loss of the configurations. This deduction is done so
that any error in the analyzer measurement can be adjusted out of both
the TX and RX Measurements.
Measure the Signal Loss in 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 is required. If required by BTS Type, an additional
Attenuator is also required for the RX Test Cable Configuration. These
additional items must be included in the Path Loss Measurement.
Measure the Signal Loss in 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.

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
Signal Loss Values in the Test Cable Insertion Loss Files. The Test
Cable Insertion Loss Values can also be set or changed manually.
CAUTION

Bay Level Offset Calibration
Introduction
Bay Level Offset (BLO) Calibration is the central activity of the
Optimization Process. BLO Calibration compensates for normal
equipment variations within the BTS RF Paths and assures that 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 are automatically 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 Cage BBX Backplane Slot, travels
through the CIO Card, is routed to the Power Amplifier (PA) Trunking
Module for Sector Phase Shifting, through the PAs, back through the PA
Trunking Module for Sector Phase Selection, through the TX Bandpass
Filter (Starter Frames) or 2:1 TX Combiner (Expansion Frames),
through the Transmit and Receive Filter (TRF) or Duplexer TX/RF Filter
(DRF), and ends at the TRF or DRF Antenna Connector..
Receive (RX) Main Path
A Main RX Path starts at ANTENNAS Connectors 1A, 2A, or 3A and
travels through the associated TRF or DRF, the MPC in the SCCP Cage
MPC–1 Slot, the CIO Card, and terminates at a Backplane BBX Slot in
the SCCP Cage..
Diversity RX Path
Diversity RX Paths differ for SC4812T Lite Starter and Expansion
Frames. The following describe each type of path.:
S Starter 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 TRF or DRF, and the MPC Card in SCCP Cage MPC–2
Slot.

Bay Level Offset Calibration
– continued
S Expansion Frame Diversity RX Path – The Starter Frame Main RX
Signal is used for the Expansion Frame Diversity RX Signal. An
Expansion Frame’s Diversity RX Path starts at ANTENNAS
Connectors 1A, 2A, or 3A in the Starter Frame. It travels through the
associated TRF or DRF, the MPC in SCCP Cage MPC–1 Slot, 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).
The signal travels through the Inter–frame Diversity RX Cables, into
the RX Expansion In Ports (RX EXPANSION 1B, 2B, or 3B) of the
Expansion Frame, through the Expansion MPC (EMPC) in SCCP
Cage MPC–2 Slot, the CIO, and terminates at a Backplane BBX Slot
in the SCCP Cage.
S RFDS sampling paths – Directional Couplers for RFDS signal
sampling are integral to the SC4812T Lite Transmit and Receive Paths
in the DRFs and TRFs. 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 BLOs
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 Cage
– CIO Card
– CIO–to–PA Trunking Module RF Cable
– PA Trunking Module
– Power Amplifier
– 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 BBX Cards
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 that contains the Calibration Data for the six Primary
BBX Slots.
2. Slot[20] Block that contains the Calibration Data for the Redundant
BBX. Refer to Table 3-38.
3. Slot[385] Block that contains the Calibration Data for the RFDS.
BBX Slot Block Parts
BBX Slot Blocks are further subdivided into the parts described in the
following paragraphs.
Slot Block Header – Each BBX Slot Block has a Header Section (Slot
Header) that contains the following items.:
S A Creation Date and Time – broken down into separate parameters of
“createMonth”, “createDay”, “createYear”, “createHour”, and
“createMin”.
S The 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.
S The slot Block format parameter.
Slot Block Bay Level Calibration Data – Each BBX Slot Block has a
Bay Level Calibration Data Section (BayLevelCal) that 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:

(CAL File Entries are Channel 0 with

S When referring to the CAL File Printout and Table 3-38, 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 Calibration 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.

In the example above, BLO was measured at only two frequencies
(Channels 384 and 777) for SCCP BBX–1 Slot Transmit (Table 3-38).
The BLO Data for the highest frequency measured (Channel 777) will
be written to the remaining eight Transmit Calibration Points (defined
by Entry C[5] through Entry 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 BBX Cards 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] through C[60]) are sent first.
Data for the ten BBX Slot 1 Calibration Points (Entries C[1] through
C[20]) are sent initially, followed by data for the ten BBX Slot 2
Calibration Points (Entries C[21] through C[40]), and so on. The RX
Calibration Data is sent next in BBX Slot Sequence, followed by the RX
Diversity Calibration Data.

For TX Path Calibration, connect the Test Equipment as shown in Figure 3-16, Figure 3-17, or
Figure 3-18, 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 BBX Cards CDF File Block.
The Channel Frequency and desired Power Output 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
Ensure that the bts–#.cdf (or bts–#.necf) 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 Output
to within +0.5 dB of the desired Power Output. The Calibration Settings
will pass if the error is less than +1.5 dB.
The TX BLO for the SC 4812T Lite is approximately 45.0 dB +5.0 dB.
BLO is the Gain in dB between the known Power Output of the BBX
and the measured Power Input at the TX Port. BLO is derived by
deducting the known BBX Power Output from the Power Input
measured at the TX Port or (Measured TX Port Power Input) – (BBX
TX Power Output).

Example:
Measured Power Input (at TX Port) = 39.0 dBm
Known BBX TX Power Output = –6.0 dBm
BLO = (39.0) – (–6.0) = 45.0 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 that opens when TX Calibration... or All
Cal/Audit... is selected contains several “user–selectable” Features
that 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 2 is only available if no 1X Cards are selected.
– 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.
Verify BLO Check Box
In both the TX Calibration and All Cal/Audit Dialog Boxes, a Verify
BLO Check Box is provided and checked by default. After the actual
TX Calibration is completed during either the TX Calibration or All
Cal/Audit Process, 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 Check Box 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 Check Box
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, 45.0 +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 BBX Cards.
FEB 2005
1X SC 4812T Lite BTS Optimization/ATP
PRELIMINARY
3-119
Bay Level Offset Calibration
– continued
Primary BBX Cards normally will have BLOs in the lower half of the
range. Using the example range, this would be from 40 to 45 dB.
Checking the Single–Sided BLO Check Box should only be done when
calibrating Primary BBX Cards 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.
IMPORTANT
Never select Single–Sided BLO when calibrating a
Redundant BBX.
Test Pattern Drop–down Pick List
The Tests > TX > TX Calibration... Menu Window has a Test Pattern
Pull–down Menu. This menu has the following choices:
S Standard – performs Calibration or Audit using Pilot, Paging, Synch,
and six Traffic Channels with IS–97–specified Gain. This Pattern
Setting should be used for all non–In–service Calibrations and Audits.
IMPORTANT
Using this Pattern Setting requires the selection of one
BBX and at least one MCC.
S Pilot (Default) – performs Calibration using only the Pilot Channel.
IMPORTANT
This Pattern Setting should be used for In–service
Calibrations, and requires selection of only one BBX.
S CDFPilot – 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).
IMPORTANT
Using this Pattern Setting requires the selection of one

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.
NOTE
RF Path Verification, BLO Calibration, and BLO Data
Download to BBX Cards must be successfully completed
prior to performing the Calibration Audit.
TX Path Audit
Perform the Calibration Audit of the TX Paths of all equipped BBX
Slots, per the steps in Table 3-43.
NOTE
If a successful All Cal/Audit was completed, this

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
the 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..

Alarm A and Alarm B Connector Comparison
The ALARM A Connector is always functional; the ALARM B
Connector is functional when an AMR Card is equipped in the AMR 2
Slot in the SCCP Cage. Refer to Figure 3-45.
The ALARM A Port monitors Input Numbers 1 through 9 and 11
through 18, while ALARM B Port monitors Input Numbers 19 through
36. Refer to Figure 3-46.
– Alarm 10 is reserved for system use.
– State Transitions on these Input Lines are reported to the LMF and
OMC–R as MGLI Input Relay Alarms.
ALARM A and ALARM B Connectors each provide 18 Inputs and 8
Outputs.
– If both A and B are functional, 36 Inputs and 16 Outputs are
available.
– They may be configured as redundant.
– The configuration is set by the CBSC.
