SCt4812T CDMA BTS Optimization/ATP DRAFT
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.
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.
IMPORTANT
*
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.
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.
CAUTION

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
1Physically verify that all DC power sources supplying power to the frame are OFF or disabled.
2On each frame:
SUnseat all circuit boards (except CCD and CIO cards) in the C–CCP shelf and LPA shelves, but
leave them in their associated slots.
SSet C–CCP shelf breakers to the OFF position by pulling out power distribution breakers (labeled
C–CCP 1, 2, 3 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).
SSet 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).
3Verify 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).
SIf reading is < 500 Ω, a short may exist somewhere in the DC distribution path supplied by the
breaker. Isolate the problem before proceeding. A reading > 3 MΩ could indicate an open (or
missing) bleeder resistor (installed across the filter capacitors behind the breaker panel).
4Set the 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* 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.
5Insert 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.
SA 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:
– (in +27 V BTS C–CCP shelf)
– (in –48 V BTS C–CCP shelf)

Power-up Procedures
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.
WARNING
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.
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.
CAUTION
For positive power applications (+27 V):
SThe positive power cable is red.
SThe negative power cable (ground) is black.
For negative power applications (–48 V):
SThe negative power cable is red or blue.
SThe positive power cable (ground) is black.
In all cases, the black power cable is at ground potential.

Optimization/Calibration – Introduction
Mar 2001 3-1
SCt4812T CDMA BTS Optimization/ATP DRAFT
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.
Before using the LMF, use an editor to view the
”CAVEATS” section in the ”readme.txt” file in the c:\wlmf
folder for any applicable information.
IMPORTANT
*
Optimization Process
After a BTS is physically installed and the preliminary operations
(power up) have been completed, the 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.

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.
For more information on the differences in site types,
please refer to the applicable BTS/Modem Frame Hardware
Installation and Functional Hardware Description
manuals.
NOTE
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:
SDownload instructions and protocol
SSite specific equipage information
SC–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.

SCt4812T CDMA BTS Optimization/ATP DRAFT
SEffective Rated Power (ERP) table for all TX channels to antennas
respectively. Motorola System Engineering specifies the ERP of a
transmit antenna based on site geography, antenna placement, and
government regulations. Working from this ERP requirement, the
antenna gain, (dependent on the units of measurement specified) and
antenna feed line loss can be combined to determine the required
power at the top of the BTS frame. The corresponding BBX output
level required to achieve that power level on any channel/sector can
also be determined.
Refer to the CDMA LMF Operator’s Guide, 68P64114A78,
for additional information on the layout of the LMF
directory structure (including CDF file locations and
formats).
NOTE
BTS System Software
Download
BTS system software must be successfully downloaded to the BTS
processor boards before optimization can be performed. BTS operating
code is loaded from the LMF computer terminal.
Before using the LMF for optimization/ATP, the correct
bts–#.cdf and cbsc–#.cdf files for the BTS must be
obtained from the CBSC and put in a bts–# folder in the
LMF. Failure to use the correct CDF files can cause wrong
results. Failure to use the correct CDF files to log into a
live (traffic carrying) site can shut down the site.
IMPORTANT
*
The CDF is normally obtained from the CBSC on a DOS formatted
diskette, or through a file transfer protocol (ftp) if the LMF computer has
ftp capability. Refer to the CDMA LMF Operator’s Guide, 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.
Always wear a conductive, high impedance wrist strap
while handling any circuit card/module to prevent damage
by ESD. Extreme care should be taken during the removal
and installation of any card/module. After removal, the
card/module should be placed on a conductive surface or
back into the anti–static bag in which it was shipped.

Isolate BTS from T1/E1 Spans
At active sites, the OMC/CBSC must disable the BTS and
place it out of service (OOS). DO NOT remove the 50–pin
TELCO cable connected to the BTS frame site I/O board
J1 connector until the OMC/CBSC has disabled the BTS!
IMPORTANT
*
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
1From 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.

–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..
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.

*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.
IMPORTANT
Table 3-4: Copying CBSC CDF Files to the LMF
nStep Action
AT THE CBSC:
1Login to the CBSC workstation.
2Insert a DOS formatted diskette in the workstation drive.
3 Type eject –q and press the <Enter> key.
4 Type mount and press the <Enter> key.
NOTE
SLook for the “floppy/no_name” message on the last line displayed.
SIf the eject command was previously entered, floppy/no_name will be appended with a
number. Use the explicit floppy/no_name reference displayed when performing step 7.
5Change to the directory containing the file by typing cd <directory name> (ex. cd
bts–248) and pressing <Enter>.
6 Type ls <Enter> to display the list of files in the directory.
7 With Solaris versions of Unix, create DOS–formatted versions of the bts–#.cdf and cbsc–#.cdf
files on the diskette by entering the following command:
unix2dos <source filename> /floppy/no_name/<target filename>
(e.g., unix2dos bts–248.cdf /floppy/no_name/bts–248.cdf).
NOTE
SOther versions of Unix do not support the unix2dos and dos2unix commands. In these cases,
use the Unix cp (copy) command. The copied files will be difficult to read with a DOS or
Windows text editor because Unix files do not contain line feed characters. Editing copied CDF
files on the LMF computer is, therefore, not recommended.
SUsing cp, multiple files can be copied in one operation by separating each filename to be copied
with a space and ensuring the destination directory (floppy/no_name) is listed at the end of the
command string following a space (e.g., cp bts–248.cdf cbsc–6.cdf /floppy/na_name).

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.
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

Basic LMF Operation
The CDMA LMF allows the user to work in the two following operating
environments, which are accessed using the specified desktop icon:
SGraphical User Interface (GUI) using the WinLMF icon
SCommand Line Interface (CLI) using the WinLMF CLI icon
The GUI is the primary optimization and acceptance testing operating
environment. The CLI environment provides additional capability to the
user to perform manually controlled acceptance tests and audit the
results of optimization and calibration actions.
Basic operation of the LMF GUI includes the following:
SSelecting and deselecting BTS devices
SEnabling devices
SDisabling devices
SResetting devices
SObtaining device status
SSorting a status report window
For detailed information on performing these and other LMF operations,
refer to the CDMA LMF Operator’s Guide, 68P64114A78.
Graphical User Interface
Overview
The LMF uses a GUI, which works in the following way:
SSelect the device or devices.
SSelect the action to apply to the selected device(s).
SWhile action is in progress, a status report window displays the action
taking place and other status information.
SThe status report window indicates when the the action is complete
and displays other pertinent information.
SClicking the OK button closes the status report window.

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 Due to architectural limitations, the
GUI must be started before the CLI if you want the GUI and CLI to use
the same handler. When the CLI is launched after the GUI, the CLI
automatically finds and uses an in–progress login session with a BTS
initiated under the GUI. This allows the use of the GUI and the CLI in
the same BTS login session. If a CLI handler is already running when
the GUI is launched (this happens if the CLI window is already running
when the user starts the GUI, or if another copy of the GUI is already
running when the user starts the GUI), a dialog window displays the
following warning message:
The CLI handler is already running.
This may cause conflicts with the LMF.
Are you sure that you want to start the application?
This window also contains yes and no buttons. Selecting yes starts the
application. Selecting no terminates the application.
CLI Format Conventions
The CLI command can be broken down in the following way:
Sverb
Sdevice including device identifier parameters
Sswitch
Soption parameters consisting of:
–keywords
–equals signs (=) between the keywords and the parameter values
–parameter values
Spaces are required between the verb, device, switch, and option
parameters. A hyphen is required between the device and its identifiers.
Following is an example of a CLI command.
measure bbx–<bts_id>–<bbx_id> rssi channel=6 sector=5
Refer to LMF CLI Commands, R15.x 68P09251A59 for a complete
explanation of the CLI commands and their use.

Logging into a BTS
Be sure that the correct bts–#.cdf and cbsc–#.cdf file is
used for the BTS. These should be the CDF files that are
provided for the BTS by the CBSC. Failure to use the
correct CDF files can result in invalid optimization.
Failure to use the correct CDF files to log into a live
(traffic carrying) site can shut down the site.
IMPORTANT
*
Logging into a BTS establishes a communications link between the BTS
and the CDMA LMF. You may be logged into more than one BTS at a
time, but only one LMF may be logged into each BTS.
Before attempting to log into the BTS, confirm the CDMA LMF is
properly connected to the BTS (see Figure 3-2).
Prerequisites
Before attempting to login to a BTS, ensure the following have been
completed:
SThe LMF operating system is correctly installed and prepared.
SA bts-nnn folder with the correct CDF and CBSC file exists.
SThe LMF is correctly installed and prepared, and the LMF computer is
connected to the BTS before starting the Windows operating system
and LMF software. If necessary, restart the computer after connecting
it to the BTS (see Table 3-2 and Figure 3-2).

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 or factory repair. 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 nor a normal part of the optimization process. It is only
done in unusual situations where the resident ROM code in the device
does not match the release level of the site operating software AND the
CBSC cannot communicate with the BTS to perform the download. If
you must download ROM code, refer to Appendix H.
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.
RAM Code
Before RAM code can be downloaded from the CDMA 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 CDMA LMF file structure. The RAM code file is selected
automatically if the file is in the \lmf\cdma\loads\n.n.n.n\code folder
(where n.n.n.n is the version number of the download code). The RAM
code file in the code folder must have the correct hardware bin number.
RAM 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). When the download is completed successfully, the device
changes to OOS-RAM (yellow). When code is downloaded to an MGLI,
the LMF automatically also downloads data, and then enables the MGLI.
When enabled, the MGLI changes to INS (green).
For non–MGLI devices, data must be downloaded after RAM code is
downloaded. To download data, the device state must be OOS–RAM
(yellow).

Download Code to Devices
Code can be downloaded to a device that is in any state. After the
download starts, the device being downloaded changes to
OOS_ROM (blue). If the download is completed successfully, the device
changes to OOS_RAM with code loaded (yellow). Prior to downloading
a device, a code file must exist. The code file is selected automatically if
the code file is in the /lmf/cdma/n.n.n.n/code folder (where n.n.n.n is the
version number of the download code that matches the “NextLoad”
parameter in the CDF file). The code file in the code folder must have

Each BTS CSM system features two CSM boards per site. In a typical
operation, the primary CSM locks its Digital Phase Locked Loop
(DPLL) circuits to GPS signals. These signals are generated by either an
on–board GPS module (RF–GPS) or a remote GPS receiver (R–GPS).
The CSM2 card is required when using the R–GPS. The GPS receiver
(mounted on CSM–1) is the primary timing reference and synchronizes
the entire cellular system. CSM–2 provides redundancy but does not
have a GPS receiver.
The BTS may be equipped with a remote GPS, LORAN–C LFR, or
HSO 10 MHz Rubidium source, which the CSM can use as a secondary
timing reference. In all cases, the CSM monitors and determines what
reference to use at a given time.
–CSMs are code loaded at the factory. This data is
retained in EEPROM. The download code procedure
is required in the event it becomes necessary to code
load CSMs with updated software versions. Use the

versions.
–For non–RGPS sites only, verify the CSM configured

* IMPORTANT
The GPS satellite system satellites are not in a geosynchronous orbit and are maintained and
operated by the United States Department of Defense (D.O.D.). The D.O.D. periodically alters
satellite orbits; therefore, satellite trajectories are subject to change. A GPS receiver that is INS
contains an “almanac” that is updated periodically to take these changes into account.
If an installed GPS receiver has not been updated for a number of weeks, it may take up to one
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.)
3NOTE
If equipped with two CSMs, the LMF should display CSM-1 as bright GREEN (INS–ACT) and
CSM–2 as dark green (INS–STB). After the CSMs have been successfully enabled, the
PWR/ALM LEDs are steady green (alternating green/red indicates the card is in an alarm state).

CSM System Time/GPS and LFR/HSO Verification
Mar 2001 3-33
SCt4812T CDMA BTS Optimization/ATP DRAFT
CSM & LFR Background
The primary function of the Clock Synchronization Manager (CSM)
boards (slots 1 and 2) is to maintain CDMA system time. The CSM in
slot 1 is the primary timing source while slot 2 provides redundancy. The
CSM2 card (CSM second generation) is required when using the remote
GPS receiver (R–GPS). R–GPS uses a GPS receiver in the antenna head
that has a digital output to the CSM2 card. CSM2 can have a daughter
card as a local GPS receiver to support an RF–GPS signal.
The CSM2 switches between the primary and redundant units (slots 1
and 2) upon failure or command. CDMA Clock Distribution
Cards (CCDs) buffer and distribute even–second reference and 19.6608
MHz clocks. CCD–1 is married to CSM–1 and CCD–2 is married to
CSM 2. A failure on CSM–1 or CCD–1 cause the system to switch to
redundant CSM–2 and CCD–2.
In a typical operation, the primary CSM locks its Digital Phase Locked
Loop (DPLL) circuits to GPS signals. These signals are generated by
either an on–board GPS module (RF–GPS) or a remote GPS receiver
(R–GPS). The CSM2 card is required when using the R–GPS. DPLL
circuits employed by the CSM provide switching between the primary
and redundant unit upon request. Synchronization between the primary
and redundant CSM cards, as well as the LFR or HSO back–up source,
provides excellent reliability and performance.
Each CSM board features an ovenized, crystal oscillator that provides
19.6608 MHz clock, even second tick reference, and 3 MHz sinewave
reference, referenced to the selected synchronization source (GPS,
LORAN–C Frequency Receiver (LFR), or High Stability Oscillator
(HSO), T1 Span, or external reference oscillator sources). The 3 MHz
signals are also routed to the RDM EXP 1A & 1B connectors on the top
interconnect panel for distribution to co–located frames at the site.
Fault management has the capability of switching between the GPS
synchronization source and the LFR/HSO backup source in the event of
a GPS receiver failure on CSM–1. During normal operation, the CSM–1
board selects GPS as the primary source (see Table 3-19). The source
selection can also be overridden via the LMF or by the system software.
All boards are mounted in the C–CCP shelf at the top of the BTS frame.
Figure 3-9 on page 3-36 illustrates the location of the boards in the BTS
frame. The diagram also shows the CSM front panel.

Low Frequency Receiver/
High Stability Oscillator
The CSM handles the overall configuration and status monitoring
functions of the LFR/HSO. In the event of GPS failure, the LFR/HSO is
capable of maintaining synchronization initially established by the GPS
reference signal.
The LFR requires an active external antenna to receive LORAN RF
signals. Timing pulses are derived from this signal, which is
synchronized to Universal Time Coordinates (UTC) and GPS time. The
LFR can maintain system time indefinitely after initial GPS lock.
The HSO is a high stability 10 MHz oscillator with the necessary
interface to the CSMs. The HSO is typically installed in those
geographical areas not covered by the LORAN–C system. Since the
HSO is a free–standing oscillator, system time can only be maintained
for 24 hours after 24 hours of GPS lock.
Upgrades and Expansions: LFR2/HSO2/HSOX
LFR2/HSO2 (second generation cards) both export a timing signal to the
expansion or logical BTS frames. The associated expansion or logical
frames require an HSO–expansion (HSOX) whether the starter frame has
an LFR2 or an HSO2. The HSOX accepts input from the starter frame
and interfaces with the CSM cards in the expansion frame. LFR and
LFR2 use the same source code in source selection (see Table 3-18).
HSO, HSO2, and HSOX use the same source code in source selection
(see Table 3-18).
Allow the base site and test equipment to warm up for
60 minutes after any interruption in oscillator power. CSM
board warm-up allows the oscillator oven temperature and
oscillator frequency to stabilize prior to test. Test
equipment warm-up allows the Rubidium standard
timebase to stabilize in frequency before any measurements
are made.
NOTE
Front Panel LEDs
The status of the LEDs on the CSM boards are as follows:
SSteady Green – Master CSM locked to GPS or LFR (INS).
SRapidly Flashing Green – Standby CSM locked to GPS or LFR

SCt4812T CDMA BTS Optimization/ATP DRAFT
HSO Initialization/Verification
The HSO module is a full–size card that resides in the C–CCP Shelf.
This completely self contained high stability 10 MHz oscillator
interfaces with the CSM via a serial communications link. The CSM
handles the overall configuration and status monitoring functions of the
HSO. In the event of GPS failure, the HSO is capable of maintaining
synchronization initially established by the GPS reference signal for a
limited time.
The HSO is typically installed in those geographical areas not covered
by the LORAN–C system and provides the following major functions:
SReference oscillator temperature and phase lock monitor circuitry
SGenerates a highly stable 10 MHz sine wave.
SReference divider circuitry converts 10 MHz sine wave to 10 MHz
TTL signal, which is divided to provide a 1 PPS strobe to the CSM.
Prerequisites
SThe LMF is not logged into the BTS.
SThe COM1 port is connected to the MMI port of the primary CSM via
a null modem board.
SThe primary CSM and the HSO (if equipped) have warmed up for 15
minutes.
If the BTS is equipped with an HSO, follow the procedure in Table 3-21
to configure the HSO.
Table 3-21: HSO Initialization/Verification
Step Action
1At the BTS, slide the HSO card into the cage.
NOTE
The LED on the HSO should light red for no longer than 15-minutes, then switch to green. The CSM
must be locked to GPS.
2On the LMF at the CSM> prompt, enter sources <cr>.
–Observe the following typical response for systems equipped with HSO:
Num Source Name Type TO Good Status Last Phase Target Phase Valid
––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––
0 Local GPS Primary 4 Yes Good 0 0 Yes
1 HSO Backup 4 Yes N/A xxxxxxx –69532 Yes
2 Not used
Current reference source number: 0
When the CSM is locked to GPS, verify that the HSO “Good” field is Yes and the “Valid” field is Yes.
3If source “1” is not configured as HSO, enter at the CSM> prompt: ss 1 12 <cr>
Check for Good in the Status field.
4At the CSM> prompt, enter sources <cr>.
Verify the HSO valid field is Yes. If not, repeat this step until the “Valid” status of Yes is returned. The
HSO should be valid within one (1) minute, assuming the DPLL is locked and the HSO Rubidium
oscillator is fully warmed.

Connecting Test Equipment to
the BTS
All test equipment is controlled by the LMF via an IEEE–488/GPIB bus.
The LMF requires each piece of test equipment to have a factory set
GPIB address. If there is a communications problem between the LMF
and any piece of test equipment, verify that the GPIB addresses have
been set correctly (normally 13 for a power meter and 18 for a CDMA
analyzer).
The following equipment is required to perform optimization:
SLMF
STest set
SDirectional coupler and attenuator
SRF cables and connectors
Refer to Table 3-22 for an overview of connections for test equipment
currently supported by the LMF. In addition, see the following figures:
SFigure 3-11 and Figure 3-12 show the test set connections for TX
calibration.
SFigure 3-13 and Figure 3-14 show the test set connections for
optimization/ATP tests.
SFigure 3-15 and Figure 3-16 show typical TX and RX ATP setup with
a directional coupler (shown with and without RFDS).
Supported Test Sets
Optimization and ATP testing may be performed using one of the
following test sets:
SCyberTest
SAdvantest R3465 and HP 437B or Gigatronics Power Meter
SHewlett–Packard HP 8935
SHewlett–Packard HP 8921 (W/CDMA and PCS Interface for
1.7/1.9 GHz) and HP 437B or Gigatronics Power Meter
SSpectrum Analyzer (HP8594E) – optional
SRubidium Standard Timebase – optional
To prevent damage to the test equipment, all TX test
connections must be through the directional coupler and
in-line attenuator as shown in the test setup illustrations.

Equipment Warm-up
Warm-up BTS equipment for a minimum of 60 minutes
prior to performing the BTS optimization procedure. This
assures BTS site stability and contributes to optimization
accuracy. (Time spent running initial power-up,
hardware/firmware audit, and BTS download counts as
warm-up time.)
IMPORTANT

Calibrating Cables
Figure 3-10 shows the cable calibration setup for various supported test
sets. The left side of the diagram depicts the location of the input and
output ports of each test set, and the right side details the set up for each
test.
Before installing any test equipment directly to any BTS
TX OUT connector, verify there are NO CDMA BBX
channels keyed. At active sites, have the OMC-R/CBSC
place the antenna (sector) assigned to the LPA under test
OOS. Failure to do so can result in serious personal injury
and/or equipment damage.

Test Set Calibration
DRAFT
SCt4812T CDMA BTS Optimization/ATP Mar 2001

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

Calibrating Cables
The cable calibration function measures the loss (in dB) for the TX and
RX cables that are to be used for testing. A CDMA analyzer is used to
measure the loss of each cable configuration (TX cable configuration and
RX cable configuration). The cable calibration consists of the following:
SMeasuring the loss of a short cable – This is required to compensate
for any measurement error of the analyzer. The short cable (used only
for the calibration process) is used in series with both the TX and RX
cable configuration when measuring. The measured loss of the short
cable is deducted from the measured loss of the TX and RX cable
configuration to determine the actual loss of the TX and RX cable
configurations. The result is then adjusted out of both the TX and RX
measurements to compensate for the measured loss.
SThe short cable plus the RX cable configuration loss is measured –
The RX cable configuration normally consists only of a coax cable
with type-N connectors that is long enough to reach from the BTS RX
port of the test equipment.

Introduction to Bay Level
Offset Calibration
Calibration compensates for normal equipment variations within the
BTS and assures maximum measurement accuracy.
RF Path Bay Level Offset
Calibration
Calibration identifies the accumulated gain in every transmit path (BBX
slot) at the BTS site and stores that value in a BLO database calibration
table in the LMF. The BLOs are subsequently downloaded to each BBX.
For starter frames, each receive path starts at a BTS RX antenna port and
terminates at a backplane BBX slot. Each transmit path starts at a BBX
backplane slot, travels through the LPA, and terminates at a BTS TX
antenna port.
For expansion frames each receive path starts at the BTS RX port of the
cell site starter frame, travels through the frame-to-frame expansion
cable, and terminates at a backplane BBX slot of the expansion frame.
The transmit path starts at a BBX backplane slot of the expansion frame,
travels though the LPA, and terminates at a BTS TX antenna port of the
same expansion frame.
Calibration identifies the accumulated gain in every transmit path (BBX
slot) at the BTS site and stores that value in a BLO database. Each
transmit path starts at a C–CCP shelf backplane BBX slot, travels
through the LPA, and ends at a BTS TX antenna port. When the TX path
calibration is performed, the RX path BLO is automatically set to the
default value.
At omni sites, BBX slots 1 and 13 (redundant) are tested. At sector sites,
BBX slots 1 through 12, and 13 (redundant) are tested. Only those slots
(sectors) actually equipped in the current CDF are tested, regardless of
physical BBX board installation in the slot.
When to Calibrate BLOs Calibration of BLOs is required:
SAfter initial BTS installation
SOnce each year
SAfter replacing any of the following components or associated
interconnecting RF cabling:
–BBX board
–C–CCP shelf
–CIO card
–CIO to LPA backplane RF cable
–LPA backplane

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

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

TX Path Calibration
The assigned channel frequency and power level (as measured at the top
of the frame) for transmit calibration are derived from the site CDF files.
For each BBX, the channel frequency is specified in the ChannelList
CDF file parameter and the power is specified in the SIFPilotPwr
CDF file parameter for the sector associated with the BBX (located
under the ParentSECTOR field of the ParentCARRIER CDF file
parameter).
If both the BTS–x.cdf and CBSC–x.cdf files are current,
all information will be correct on the LMF. If not, the
carrier and channel will have to be set for each test.
NOTE
The calibration procedure attempts to adjust the power to within +0.5 dB
of the desired power. The calibration will pass if the error is less than
+1.5 dB.
The TX Bay Level Offset at sites WITHOUT the directional coupler
option, is approximately 42.0 dB ±3.0 dB.
SAt sites WITHOUT RFDS option, BLO is approximately
42.0 dB ±4.0 dB. A typical example would be TX output power
measured at BTS (36.0 dBm) minus the BBX TX output level
(approximately –6.0 dBm) would equate to 42 dB BLO.
The TX Bay Level Offset at sites WITH the directional coupler option,
is approximately 41.4 dB ±3.0 dB. TX BLO = Frame Power Output
minus BBX output level.
SExample: TX output power measured at RFDS TX coupler
(39.4 dBm) minus the BBX TX output level (approximately
–2.0 dBm) and RFDS directional coupler/cable (approximately
–0.6 dBm) would equate to 41.4 dB BLO.
The LMF Tests menu list items, TX Calibration and All Cal/Audit,
perform the TX BLO Calibration test for a XCVR(s). The All Cal/Audit
menu item performs TX calibration, downloads BLO, and performs TX
audit if the TX calibration passes. All measurements are made through
the appropriate TX output connector using the calibrated TX cable setup.

Calibration Audit Introduction
The BLO calibration audit procedure confirms the successful generation
and storage of the BLO calibration offsets. 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 is
used.
*RF path verification, BLO calibration, and BLO data
download to BBXs must have been successfully completed
prior to performing the calibration audit.

RFDS Calibration
The RFDS TX and RX antenna paths must be calibrated to ensure peak
performance. The RFDS calibration option calibrates the RFDS TX and
RX paths.
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.
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 XCVR. A CDMA signal at the same power level measured by the
BTS XCVR is then injected at the RX antenna directional coupler by the
RFDS keyed power level and the power level measured at the BTS
XCVR is the RFDS RX calibration offset value.
The TX and RX RFDS calibration offset values are written to the CAL
file.
Prerequisites
Ensure the following prerequisites have been met before proceeding:
SBBXs are INS_TEST.
SCable calibration has been performed

SCt4812T CDMA BTS Optimization/ATP DRAFT
Objective
This section tests the redundancy options that could be included in the
cell site. These tests verify, under a fault condition, that all modules
equipped with redundancy switch operations to their redundant partner
and resume operation. An example would be to pull the currently active
CSM and verify the standby CSM takes over distribution of the CDMA
reference signal.
Redundancy covers many BTS modules. Confirm the redundant options
included in the BTS, and proceed as required. If the BTS has only basic
power supply redundancy, the tests and procedures detailed in the
following tables should be bypassed.
STable 3-48. Miscellaneous Alarm Tests (BTS Frame)
STable 3-49. BBX Redundancy Tests (BTS Frame)
STable 3-50. CSM, GPS, & LFR/HSO Redundancy Alarm Tests
STable 3-51. LPA Redundancy Test
STable 3-52. MGLI/GLI Redundancy Test
During redundancy verification of the test, alarms reported by the master
GLI (displayed via the alarm monitor) will also be verified/noted.
Test Equipment
The following pieces of test equipment are required to perform this test:
SLMF
SCommunications Test Set
Redundancy/Alarm Test
Perform each of the following tests to verify BTS redundancy and to
confirm all alarms are received and reported by the BTS equipment. The
procedures should be performed on the following modules/boards:
SPower supply/converter modules in all frames
SDistribution shelf modules in the BTS frame
SC–CCP shelf modules in the BTS frame (except MCCs)

LPA Redundancy Test
Follow the procedure in Table 3-51 to verify redundancy of the LPAs.
First verify there are no BBX channels keyed BEFORE
moving the antenna connection. Failure to do so can result
in serious personal injury and/or equipment damage.
WARNING
Table 3-51: LPA Redundancy Test
Step Action
1From the pulldown menu select:
Device > Set Redundant Sector > None/0
Device > Set Pilot > Only > Carrier–#–1-1
Device > Set Pilot > Only > Carrier–#-1-1 and Pilot Gain = 262
2Key-up the BBX assigned to the LPAs associated with the sector under test (gain = 40).
3Adjust the communications test set spectrum analyzer, as required, to observe the overall carrier
amplitude and IM Shelf and note for reference. These figures will be required later.
NOTE
See Figure 3-13 for test equipment setup, if required.
4Push-in and release the breaker supplying the 1st LPA of the pair.
NOTE
After power is removed, IM suppression takes a few seconds to settle out while compensating for the
removal of the 1st LPA. The overall gain decreases by approximately 6 dB. The process must be
complete before proceeding.
5 Verify:
•The other LPA module did not go OOS due to the loss of the LPA.
•The overall carrier amplitude is reduced by approximately 6 dB and IM suppression on the analyzer
display remains basically unchanged.
•LPA fault message is reported via the MGLI and displayed on the alarm monitor.
6Re-apply power to the LPA module and observe the alarm has cleared on the alarm monitor.
NOTE
All PWR/ALM LEDs should be GREEN at completion of test.
7Repeat Steps 4 through 6 to verify the 2nd LPA of the pair.
8De-key the BBX.
n WARNING
First verify there are no BBX channels keyed when moving the antenna connection. Failure to do so
can result in serious personal injury and/or equipment damage.
9Repeat Steps 1 through 8 to verify LPAs assigned to sectors 2 and 3 (if equipped). Move the test cable
on top of the BTS to TX OUT 2 and TX OUT 3 antenna connectors as required.

MGLI/GLI Redundancy Test
This test can only be performed when the MM path is
established by the MM (not just with LAPD link
connected). Attempting to force the GLIs to “hot swap”
under alarm monitor control, when isolated from the MM,
causes MGLIs to hang up.
CAUTION
Table 3-52: MGLI/GLI Redundancy Test (with MM Connection Established)
Step Action
NOTE
SThis test assumes the alarm monitor is NOT connected to the BTS and the T1/E1 span is connected
and communication is established with the MM.
SBOTH GLIs must be INS before continuing.
1Verify the BBXs are enabled and a CDMA carrier is present.
2Identify the primary and redundant MGLI pairs.
3Pull the MGLI that is currently INS–ACT and has cage control.
4Observe the BBX remains GREEN, and the redundant MGLI is now active.
5Verify no other modules go OOS due to the transfer of control to the redundant module.
6Verify that the BBXs are enabled and a CDMA carrier is present.
7Reinstall the MGLI and have the OMCR/CBSC place it back in-service.
8Repeat Steps 1 through 7 to verify the other MGLI/GLI board.

BTS Alarms Testing
Mar 2001 3-97
SCt4812T CDMA BTS Optimization/ATP DRAFT
Alarm Test Overview
ALARM connectors provide Customer Defined Alarm Inputs and
Outputs. The customer can connect BTS site alarm input sensors and
output devices to the BTS, thus providing alarm reporting of active
sensors as well controlling output devices.
The SC 4812T is capable of concurrently monitoring 36 input signals
coming into the BTS. These inputs are divided between 2 Alarm
connectors marked ‘ALARM A’ and ‘ALARM B’ located at the top of
the frame (see Figure 3-24). The ALARM A connector is always
functional; ALARM B is functional when an AMR module is equipped
in the AMR 2 slot in the distribution shelf. ALARM A port monitors
input numbers 1 through 18, while ALARM B port monitors input
numbers 19 through 36 (see Figure 3-25). State transitions on these input
lines are reported to the LMF and OMCR 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.
Alarm Reporting Display
The Alarm Monitor window can be displayed to list alarms that occur
after the window is displayed. To access the Alarm Monitor window,
select Util>Alarm Monitor.
The following buttons are included:
SThe Options button allows for a severity level (Warning, Minor, and
Major) selection. The default is all levels. To change the level of
alarms reported click on the Options button and highlight the desired
alarm level(s). To select multiple levels press the <Ctrl> key (for
individual selections) or <Shift> key (for a range of selections) while
clicking on the desired levels.
SThe Pause button pauses/stops the display of alarms. When the Pause
button is clicked the name of the button changes to Continue. When
the Continue button is clicked, the display of alarms continues.
Alarms that occur between the time the Pause button is clicked and
the Continue button is clicked are not displayed.
SThe Clear button clears the Alarm Monitor display. New alarms that
occur after the Clear button is clicked are displayed.
SThe Dismiss button dismisses/closes the Alarm Monitor display.

Purpose The following procedures verify the customer defined alarms and relay
contacts are functioning properly. These tests are performed on all AMR
alarms/relays in a sequential manner until all have been verified. Perform
these procedures periodically to ensure the external alarms are reported
properly. Following these procedures ensures continued peak system
performance.
Study the site engineering documents and perform the following tests
only after first verifying that the AMR cabling configuration required to
interconnect the BTS frame with external alarm sensors and/or relays
meet requirements called out in the SC 4812T Series BTS Installation
Manual.
Motorola highly recommends that you read and understand
this procedure in its entirety before starting this procedure.
