General Safety
Remember! . . . Safety
depends on you!!
The following general safety precautions must be observed during all
phases of operation, service, and repair of the equipment described in
this manual. Failure to comply with these precautions or with specific
warnings elsewhere in this manual violates safety standards of design,
manufacture, and intended use of the equipment. Motorola, Inc. assumes
no liability for the customer’s failure to comply with these requirements.
The safety precautions listed below represent warnings of certain dangers
of which we are aware. You, as the user of this product, should follow
these warnings and all other safety precautions necessary for the safe
operation of the equipment in your operating environment.
Ground the instrument
To minimize shock hazard, the equipment chassis and enclosure must be
connected to an electrical ground. If the equipment is supplied with a
three-conductor ac power cable, the power cable must be either plugged
into an approved three-contact electrical outlet or used with a
three-contact to two-contact adapter. The three-contact to two-contact
adapter must have the grounding wire (green) firmly connected to an
electrical ground (safety ground) at the power outlet. The power jack and
mating plug of the power cable must meet International Electrotechnical
Commission (IEC) safety standards.
Do not operate in an explosive
atmosphere
Do not operate the equipment in the presence of flammable gases or
fumes. Operation of any electrical equipment in such an environment
constitutes a definite safety hazard.
Keep away from live circuits
Operating personnel must:
not remove equipment covers. Only Factory Authorized Service
Personnel or other qualified maintenance personnel may remove
equipment covers for internal subassembly, or component
replacement, or any internal adjustment.
not replace components with power cable connected. Under certain
conditions, dangerous voltages may exist even with the power cable
removed.
always disconnect power and discharge circuits before touching them.
Do not service or adjust alone
Do not attempt internal service or adjustment, unless another person,
capable of rendering first aid and resuscitation, is present.

Optimization Manual: Scope and Layout
Scope of This Document
This document provides information pertaining to the optimization and
audit tests of Motorola SC 4812T Base Transceiver Subsystem (BTS)
equipment frames equipped with trunked high–power Linear Power
Amplifiers (LPAs) and their associated internal and external interfaces.
This document assumes the following prerequisites:
The BTS frames and cabling have been installed per the BTS Frame
Installation Manual – 68P09226A18, which covers the physical “bolt
down” of all SC series equipment frames, and the SC 4812T CDMA BTS
Installation Manual –68P64113A87 which covers BTS specific cabling
configurations.
In most applications the same test procedure is used for all equipment
variations. However, decision break points are provided throughout the
procedure when equipment specific tests are required.
IMPORTANT
As the CDMA Local Maintenance Facility (LMF)
capability comes on–line, applicable LMF based
procedures will be incorporated. Eventually, only the
CDMA LMF platform will be supported as the
recommended customer method of interfacing with and
servicing the SC series BTS equipment.
We at Motorola Technical Education & Documentation have strived to
incorporate into this document the many suggestions and inputs received
from you, the customer, since the inception of the SC product line. At
the same time, we have tried to insure that the scope of the document
targets both the novice and expert site technician and engineer with
the information required to successfully perform the task at hand. If
in some areas, the manual seems to cover the test in too much detail (or
not enough detail) we hope you will keep this in mind.

Purpose of the Optimization
Why Optimize?
Proper optimization and calibration assures:
Accurate downlink RF power levels are transmitted from the site.
Accurate uplink signal strength determinations are made by the site.
What Is Optimization?
Optimization compensates for the site-specific cabling and normal
equipment variations. Cables that interconnect the BTS and Duplexer
assemblies (if used), for example, are cut and installed at the time of the
BTS frame installation at the site. Site optimization guarantees that the
combined losses of the new cables and the gain/loss characteristics and
built-in tolerances of each BTS frame do not accumulate, causing
improper site operation.
Optimization identifies the accumulated loss (or gain) for all receive and
transmit paths at the BTS site, and stores that value in a database.
The RX path for the starter frame starts at the ancillary equipment
frame RFDS RX directional coupler antenna feedline port, through the
ancillary equipment frame RFDS RX directional coupler antenna
feedline port, through the RX input port on the top of the frame,
through the bandpass filter, Combiner Input/Output (CIO) card,
Multicoupler Preselector Card (MPC), and additional splitter circuitry,
ending at a Code Division Multiple Access (CDMA) Channel
Processor (C–CCP) backplane Broad Band Transceiver (BBX2) slot in
the C–CCP shelf.
The RX path for the expansion frame starts at the ancillary equipment
frame RFDS RX directional coupler antenna feedline port, through the
ancillary equipment frame RFDS RX directional coupler antenna
feedline port, through the RX input port on the top of the starter
frame, through the bandpass filter and CIO card, out the expansion
port at the top of the starter frame, through the expansion cable to the
expansion port on the expansion frame, through the Expansion
Multicoupler Preselector Card (EMPC) and CIO, ending at a Broad
Band Transceiver (BBX2) slot in the C–CCP shelf.
The TX path starts at the BBX2, through the C–CCP backplane slot,
travels through the LPA/Combiner TX Filter and ends at the top of the
RFDS TX directional coupler antenna feedline port (CDMA), installed
on the ancillary equipment frame. If the RFDS option is added, then
the TX path continues and ends at the top of the RFDS TX directional
coupler antenna feedline port installed in the ancillary equipment
frame. The TX paths are identical for the starter and expansion
frames.

Purpose of the Optimization – continued
These values are factored in by the BTS equipment internally, leaving
only site specific antenna feed line loss and antenna gain characteristics
to be factored in by the CFE when determining site Effective Radiated
Power (ERP) output power requirements.
Each C–CCP shelf BBX2 board is optimized to a specific RX and TX
antenna port. (One BBX2 board acts in a redundant capacity for BBX2’s
1–12, and is optimized to all antenna ports.) A single value is generated
for each path, thereby eliminating the accumulation of error that would
occur from individually measuring and summing the gain and loss of
each element in the path.
When to Optimize
New Installations
After the initial site installation, it must be prepared for operation. This
preparation includes verifying hardware installation, initial power–up,
download of operating code, and Clock Synchronization Module (CSM)
verification.
Next, the optimization is performed. Optimization includes performance
verification and calibration of all transmit and receive RF paths, and
download of accumulated calibration data.
After optimization, a series of manual pre–ATP verification tests are
covered that address alarm/redundancy tests.
After manual pre–Acceptance Test Procedure (pre–ATP) verification
tests, a series of manual ATP CDMA verification tests are covered using
the actual equipment set up. An ATP is also required before the site can
be placed in service.
Site Expansion
Optimization is also required after expansion of a site.
Periodic Optimization
Periodic optimization of a site may also be required, depending on the
requirements of the overall system.
Repaired Sites

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

BTS Frame Description
The BTS is the interface between the span lines to/from the Cellsite Base
Station Controller (CBSC) and the site antennas. This frame is described
in three sections:
The top interconnect plate where all connections are made.
The upper portion of the frame which houses circuit breakers, cooling
fans, and the Combined CDMA Channel Processor (C–CCP) shelf.
The lower portion of the frame which houses the LPA fans, LPAs, and
TX filter/combiners.
The –48 V version of the BTS also has a section below the LPAs
containing a power conversion shelf that supplies power to the LPAs.
Use the illustrations that follow to visually identify the major
components, that make up the Motorola SC 4812T BTS frame.

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

Preliminary Operations: Overview
Introduction
This section first verifies proper frame equipage. This includes verifying
module placement, jumper, and dual in–line package (DIP) switch
settings against the site-specific documentation supplied for each BTS
application. Next, pre-power up and initial power-up procedures are
presented.
Cell Site Types
Sites are configured as Omni with a maximum of 4 carriers, 3–sectored
with a maximum of 4 carriers, and 6–sectored with a maximum of 2
carriers. Each type has unique characteristics and must be optimized
accordingly. For more information on the differences in site types, please
refer to the BTS/Modem Frame Hardware Installation manual.
CDF
The Cell-site Data File (CDF) contains site type and equipage data
information and passes it directly to the LMF during optimization. The
number of modem frames, C–CCP shelves, BBX2 boards,
MCC24/MCC8E boards (per cage), and linear power amplifier
assignments are some of the equipage data included in the CDF.
IMPORTANT
Be sure that the correct bts–#.cdf and cbsc–#.cdf files are
used for the BTS. These should be the CDF files that are
provided for the BTS by the CBSC. Failure to use the
correct CDF files can cause system errors. Failure to use
the correct CDF files to log into a live (traffic carrying)
site can shut down the site.
Site Equipage Verification
Review the site documentation. Match the site engineering equipage data
to the actual boards and modules shipped to the site. Physically inspect
and verify the equipment provided for the BTS or Modem frame and
ancillary equipment frame.
CAUTION
Always wear a conductive, high impedance wrist strap
while handling any circuit card/module to prevent damage
by ESD. After removal, the card/module should be placed
on a conductive surface or back into the anti–static
shipping bag.
Initial Installation of
Boards/Modules
Follow the procedure in Table 2-1 to verify the initial installation of
boards/modules.

DC Power Pre-test (BTS Frame)
Before applying any power to the BTS frame, follow the procedure in
Table 2-2 while referring to Figure 2-3 and Figure 2-4 for +27 V
systems or to Figure 2-5 and Figure 2-6 for –48 V systems to verify
there are no shorts in the BTS frame DC distribution system.
Table 2-2: DC Power Pre–test (BTS Frame)
Step
Action
Physically verify that all DC power sources supplying power to the frame are OFF or disabled.
On each frame:
Unseat all circuit boards (except CCD and CIO cards) in the C–CCP shelf and LPA shelves, but
leave them in their associated slots.
Set C–CCP shelf breakers to the OFF position by pulling out power distribution breakers (labeled
C–CCP 1, 2, 3 on the +27 V BTS C–CCP power distribution panel and labeled POWER
1,4,5,2,6,7,3,8,9 on the –48 V C–CCP power distribution panel).
Set LPA breakers to the OFF position by pulling out the LPA breakers (8 breakers, labeled 1A–1B
through 4C–4D – located on the C–CCP power distribution panel in the +27 V BTS or on the power
conversion shelf power distribution panel in the –48 V BTS).
Verify that the resistance from the power (+ or –) feed terminals with respect to the ground terminal on
the top of the frame measures > 500 Ω (see Figure 2-3).
If reading is < 500 Ω, a short may exist somewhere in the DC distribution path supplied by the
breaker. Isolate the problem before proceeding. A reading > 3 MΩ could indicate an open (or
missing) bleeder resistor (installed across the filter capacitors behind the breaker panel).
Set the C–CCP (POWER) breakers to the ON position by pushing them IN one at a time. Repeat
Step 3 after turning on each breaker.
* IMPORTANT
If the ohmmeter stays at 0 Ω after inserting any board/module, a short probably exists in that
board/module. Replace the suspect board/module and repeat the test. If test still fails, isolate the
problem before proceeding.
Insert and lock the DC/DC converter modules for the C–CCP shelf and into their associated slots one
at a time. Repeat Step 3 after inserting each module.
A typical response is that the ohmmeter steadily climbs in resistance as capacitors charge, finally
indicating approximately 500 Ω.
! CAUTION
Verify the correct power/converter modules by observing the locking/retracting tabs appear as follows:
STPN4009
– PWR CONV
CDMA RCVR (in +27 V BTS C–CCP shelf)
STPN4045A
– PWR CONV CDMA RCVR (in –48 V BTS C–CCP shelf)
Insert and lock all remaining circuit boards and modules into their associated slots in the C–CCP shelf.
Repeat Step 3 after inserting and locking each board or module.
A typical response is that the ohmmeter steadily climbs in resistance as capacitors charge, stopping
at approximately 500 Ω..

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

Initial Power–up Tests
Power-up Procedures
WARNING
Potentially lethal voltage and current levels are routed to
the BTS equipment. This test must be performed with a
second person present, acting in a safety role. Remove all
rings, jewelry, and wrist watches prior to beginning this
test.
DC Input Power
In the tests to follow, power will first be verified at the input to each
BTS frame. After power is verified, cards and modules within the frame
itself will be powered up and verified one at a time.
Before applying any power, verify the correct power feed and return
cables are connected between the power supply breakers and the power
connectors at the top of each BTS frame. Verify correct cable position
referring to Figure 2-3 on page 2-7 for +27 V systems and Figure 2-5 on
page 2-9 for –48 V systems.
CAUTION
Always wear a conductive, high impedance wrist strap
while handling any circuit card/module to prevent damage
by ESD. Extreme care should be taken during the removal
and installation of any card/module. After removal, the
card/module should be placed on a conductive surface or
back into the anti–static bag in which it was shipped.
IMPORTANT
For positive power applications (+27 V):
The positive power cable is red.
The negative power cable (ground) is black.
For negative power applications (–48 V):
The negative power cable is red or blue.
The positive power cable (ground) is black.
In all cases, the black power cable is at ground potential.
Motorola recommends that the DC input power cable used to connect the
frame to the main DC power source conforms to the guidelines outlined
in Table 2-4.

IMPORTANT
If Anderson SB350 style power connectors are used, make
sure the connector adapters are securely attached to each of
the BTS power feeds and returns. Also, make sure the
cables have been properly installed into each connector.
Common Power Supply
Verification
The procedure in Table 2-5 must be performed on any BTS frame
connected to a common power supply at the site after the common power
supply has been installed and verified per the power supply OEM
suggested procedures.
Perform the following steps to verify the power input is within
specification before powering up the individual cards/modules with the
frames themselves.
Table 2-5: Common Power Supply Verification
Step
Action
Physically verify that all DC power sources supplying the frame are OFF or disabled.
On the RFDS (for +27 V systems only), set the input power switch P1 to the OFF position (see
Figure 2-7).
On each frame:
Unseat all circuit boards (except CCD and CIO cards) in the C–CCP shelf and Linear Power
Amplifier (LPA) shelves, but leave them in their associated slots.
Set breakers to the OFF position by pulling out C–CCP and LPA breakers (see Figure 2-3 on
page 2-7 or Figure 2-5 on page 2-9 for breaker panel layout if required).
– C–CCP shelf breakers are labeled CCCP–1, 2, 3 in the +27 V BTS and labeled POWER
1,4,5,2,6,7,3,8,9 in the –48 V BTS.
– LPA breakers are labeled 1A–1B through 4C–4D.
Inspect input cables, verify correct input power polarity via decal on top of frame (+27 Vdc or
–48 Vdc).
Apply power to BTS frames, one at a time, by setting the appropriate breaker in the power supply that
supplies the frame to the ON position.
After power is applied to each frame, use a digital voltmeter to verify power supply output voltages at
the top of each BTS frame are within specifications: +27.0 Vdc or –48 Vdc nominal.

Initial Power-up (RFDS)
The procedure in Table 2-6 must be performed on the RFDS after input
power from the common power supply has been verified. Perform the
following steps to apply initial power to the cards/modules within the
frame itself, verifying that each is operating within specification.
IMPORTANT
Visual inspection of card placement and equipage for each
frame vs. site documentation must be completed, as
covered in Table 2-1, on page 2-2, before proceeding with
this test.

Step
Action
On the RFDS, set the input power rocker switch (P1) to the ON position (see Figure 2-7).
Verify power supply output voltages (at the top of BTS frame), using a digital voltmeter, are within
specifications: +27.0 V nominal.
Initial Power-up (BTS)
The procedure must be performed on each frame after input power from
the common power supply has been verified. Follow the steps in
Table 2-7 to apply initial power to the cards/modules within the frame
itself, verifying that each is operating within specification.
Table 2-7: Initial Power–up (BTS)
Step
Action
At the BTS, set the C–CCP (POWER) power distribution breakers (see Figure 2-3 on page 2-7 or
Figure 2-5 on page 2-9) to the ON position by pushing in the breakers.
Insert the C–CCP fan modules. Observe that the fan modules come on line.
! CAUTION
Verify the correct power/converter modules by observing the locking/retracting tabs appear as follows:
STPN4009
– PWR CONV
CDMA RCVR (in +27 V BTS C–CCP shelf)
STPN 4045A
– PWR CONV CDMA RCVR (in –48 V BTS C–CCP shelf)
STPN 4044A
– PWR
(in –48 V BTS power conversion shelf)
CONV LPA
Insert and lock the converter/power supplies into their associated slots one at a time.
• If no boards have been inserted, all three PWR/ALM LEDs would indicate RED to notify the user
that there is no load on the power supplies.
– If the LED is RED, do not be alarmed. After Step 4 is performed, the LEDs should turn GREEN;
if not, then a faulty converter/power supply module is indicated and should be replaced before
proceeding.

Optimization/Calibration – Introduction
Introduction
This section describes procedures for downloading system operating
software, CSM reference verification/optimization, set up and calibration
of the supported test equipment, transmit/receive path verification, and
using the RFDS.
IMPORTANT
Before using the LMF, use an editor to view the
”CAVEATS” section in the ”readme.txt” file in the c:\wlmf
folder for any applicable information.
Optimization Process
After a BTS is physically installed and the preliminary operations
(power up) have been completed, the LMF is used to calibrate and
optimize the BTS. Motorola recommends that the optimization be
accomplished as follows:
1. Download MGLI2–1 with code and data and then enable MGLI2–1.
2. Use the status function and verify that all of the installed devices of
the following types respond with status information: CSM, BBX2,
GLI2, and MCC (and TSU if RFDS is installed). If a device is
installed and powered up but is not responding and is colored gray in
the BTS display, the device is not listed in the CDF file. The CDF
file will have to be corrected before the device can be accessed by
the LMF.
3. Download code and data to all devices of the following types:
– CSM
– BBX2
– GLI2 (other than MGLI2–1)
– MCC
4. Download the RFDS TSIC (if installed).
5. Verify the operation of the GPS and HSO signals.
6. Enable the following devices (in the order listed):
– Secondary CSM
– Primary CSM
– All MCCs
7. Connect the required test equipment for a full optimization.
8. Select the test equipment.
9. Calibrate the TX and RX test cables if they have not previously been
calibrated using the CDMA LMF that is going to be used for the
optimization/calibration. The cable calibration values can also be
entered manually.

Optimization/Calibration – Introduction – continued
10. Select all of the BBXs and all of the MCCs and use the full
optimization function. The full optimization function performs TX
calibration, BLO download, TX audit, all TX tests, and all RX tests
for all selected devices.
11. If the TX calibration fails, repeat the full optimization for any failed
paths.
12. If the TX calibration fails again, correct the problem that caused the
failure and repeat the full optimization for the failed path.
13. If the TX calibration and audit portion of the full optimization passes
for a path but some of the TX or RX tests fail, correct the problem
that caused the failure and run the individual tests as required until
all TX and RX tests have passed for all paths.
Cell Site Types
Sites are configured as Omni/Omni or Sector/Sector (TX/RX). Each type
has unique characteristics and must be optimized accordingly.
NOTE
For more information on the differences in site types,
please refer to the applicable BTS/Modem Frame Hardware
Installation and Functional Hardware Description
manuals.
Cell Site Data File (CDF)
The CDF contains information that defines the BTS and data used to
download files to the devices. A CDF file must be placed in the
applicable BTS folder before the LMF can be used to log into that BTS.
CDF files are normally obtained from the CBSC using a floppy disk. A
file transfer protocol (ftp) method can be used if the LMF computer has
that capability.
The CDF includes the following information:
Download instructions and protocol
Site specific equipage information
C–CCP shelf allocation plan
– BBX2 equipage (based on cell–site type) including redundancy
– CSM equipage including redundancy
– Multi Channel Card (MCC24 or MCC8E) 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) MCC24s or MCC8Es in the shelf.

Optimization/Calibration – Introduction – continued
Effective Rated Power (ERP) table for all TX channels to antennas
respectively. Motorola System Engineering specifies the ERP of a
transmit antenna based on site geography, antenna placement, and
government regulations. Working from this ERP requirement, the
antenna gain, (dependent on the units of measurement specified) and
antenna feed line loss can be combined to determine the required
power at the top of the BTS frame. The corresponding BBX2 output
level required to achieve that power level on any channel/sector can
also be determined.
NOTE
Refer to the CDMA LMF Operator’s Guide, 68P64114A21,
for additional information on the layout of the LMF
directory structure (including CDF file locations and
formats).
BTS System Software
Download
BTS system software must be successfully downloaded to the BTS
processor boards before optimization can be performed. BTS operating
code is loaded from the LMF computer terminal.
IMPORTANT
Before using the LMF for optimization/ATP, the correct
bts–#.cdf and cbsc–#.cdf files for the BTS must be
obtained from the CBSC and put in a bts–# folder in the
LMF. Failure to use the correct CDF files can cause wrong
results. Failure to use the correct CDF files to log into a
live (traffic carrying) site can shut down the site.
The CDF is normally obtained from the CBSC on a DOS formatted
diskette, or through a file transfer protocol (ftp) if the LMF computer has
ftp capability. Refer to the CDMA LMF Operator’s Guide, or the LMF
Help screen, for the procedure.
Site Equipage Verification
If you have not already done so, use an editor to view the CDF, and
review the site documentation. Verify the site engineering equipage data
in the CDF matches the actual site hardware using a CDF conversion
table.
CAUTION
Always wear a conductive, high impedance wrist strap
while handling any circuit card/module to prevent damage
by ESD. Extreme care should be taken during the removal
and installation of any card/module. After removal, the
card/module should be placed on a conductive surface or
back into the anti–static bag in which it was shipped.

Isolate Span Lines/Connect LMF
Isolate BTS from T1/E1 Spans
IMPORTANT
At active sites, the OMC/CBSC must disable the BTS and
place it out of service (OOS). DO NOT remove the 50–pin
TELCO cable connected to the BTS frame site I/O board
J1 connector until the OMC/CBSC has disabled the BTS!
Each frame is equipped with one Site I/O and two Span I/O boards. The
Span I/O J1 connector provides connection of 25 pairs of wire. 8 pairs
are used to support up to four 4–wire span lines. 17 pairs are connected
to signal ground.
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

Preparing the LMF
Overview
Software and files for installation and updating of the LMF are provided
on CD ROM disks. The following installation items must be available:
LMF Program on CD ROM
LMF Binaries on CD ROM
Configuration Data File (CDF) for each supported BTS (on diskette or
available from the CBSC)
CBSC File for each supported BTS (on diskette or available from the
CBSC)
The following section provides information and instructions for
installing and updating the LMF software and files.
Graphical User Interface
Overview
The LMF uses a graphical user interface (GUI), which works in the
following way:
Select the device or devices.
Select the action to apply to the selected device(s).
While action is in progress, a status report window displays the action
taking place and other status information.
The status report window indicates when the the action is complete
and displays other pertinent information.
Clicking the OK button closes the status report window.
Logical BTS
The BTS software implements the logical BTS capability, also known as
virtual BTS. Previously, all BTS frames co–located at a single site had to
be identified in the network with separate and distinct BTS ID numbers.
In the Logical BTS feature, all frames located at a single BTS site are
identified with unique Frame ID numbers (Frame ID Numbers 1, 101,
201, 301) under a single (site) BTS ID number. A logical BTS can
consist of up to four SC 4812T frames.When the LMF is connected to
frame 1 of a logical BTS, you can access all devices in all of the frames
that make up the logical BTS. A logical BTS requires a CDF file that
includes equipage information for all of the logical BTS frames and their
devices and a CBSC file that includes channel data for all of the logical
BTS fames.

Logical BTS Numbering
The first frame of a logical BTS has a –1 suffix (e.g., BTS–812–1).
Other frames of the logical BTS are numbered with suffixes, –101, –201,
and –301 (e. g. BTS–812–201). When you log into a BTS, a FRAME
tab is displayed for each frame. If there is only one frame for the BTS,
there is only one tab (e.g., FRAME–282–1) for BTS–282. If a logical
BTS has more than one frame, there is a separate FRAME tab for each
frame (e.g. FRAME–438–1, FRAME–438–101, and FRAME–438–201
for a BTS–438 that has three frames). If an RFDS is included in the
CDF file, an RFDS tab (e.g., RFDS–438–1) is displayed. Figure 3-3
shows frame configurations available under the Logical BTS feature.
This figure also shows the Inter–frame spans between the different
frames at the BTS site.
Actions (e.g., ATP tests) can be initiated for selected devices in one or
more frames of a logical BTS. Refer to the Select devices help screen for
information on how to select devices.
C–CCP Shelf Card/Module Device ID Numbers
All cards/modules/boards in the frames at a single site, assigned to a
single BTS number, are also identified with unique Device ID numbers
dependent upon the Frame ID number in which they are located. Refer to
Table 3-3 and Table 3-4 for specific C–CCP Shelf Device ID numbers.

Program and Binaries Update Procedure
Follow the procedure in Table 3-5 to update the LMF program and
binaries.
NOTE
First Time Installations:
– Install Java Runtime Environment (First)
– Install LMF Software (Second)
– Install BTS Binaries (Third)
– Install/Create BTS Folders (Fourth)
NOTE
If applicable, a separate CD ROM of BTS Binaries may be
available for binary updates.
Table 3-5: CD ROM Installation
Step
Action
Insert the LMF Program CD ROM into the LMF CD ROM drive.
– If the Setup screen is displayed, follow the instructions provided.
– If the Setup screen is not displayed, proceed to step 2.
Click on the Start button.
Select Run.
In the Open box, enter d:\autorun and click on the OK button.
NOTE
If applicable, replace the letter d with the correct CD ROM drive letter.
Follow the instructions displayed in the Setup screen.
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.
. . . continued on next page
May 2000
SC 4812T CDMA BTS Optimization/ATP
3-9
Preparing the LMF
– continued
Follow the procedure in Table 3-6 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
68P64114A21) or the LMF Help screen..
NOTE
If the LMF has ftp capability, the ftp method can be used to
copy the CDF files from the CBSC.
On Sun OS workstations, the unix2dos command can be
used in place of the cp command (e.g., unix2dos
bts–248.cdf bts–248.cdf). This should be done using a
copy of the CBSC CDF file so the original CBSC CDF file
is not changed to DOS format.
IMPORTANT
When copying CDF files, comply with the following to
prevent BTS login problems with the LMF:
– The numbers used in the bts–#.cdf and cbsc–#.cdf
filenames must correspond to the locally assigned numbers
for each BTS and its controlling CBSC.
– The generic cbsc–1.cdf file supplied with the LMF work
with locally numbered BTS CDF files. Using this file does
not provide a valid optimization unless the generic file is
edited to replace default parameters (e.g., channel numbers)
with the operational parameters used locally.
Table 3-6: Copying CBSC CDF Files to the LMF
Step
Action
AT THE CBSC:
Login to the CBSC workstation.
Insert a DOS formatted diskette in the workstation drive.
Type eject –q and press the key.
Type mount and press the key.
NOTE
Look for the “floppy/no_name” message on the last line displayed.
If the eject command was previously entered, floppy/no_name will be appended with a number.
Use the explicit floppy/no_name reference displayed when performing step 7.

Table 3-6: Copying CBSC CDF Files to the LMF
Step
Action
Change to the directory containing the file by typing cd (ex. cd bts–248) and
pressing .
Type ls to display the list of files in the directory.
With Solaris versions of Unix, create DOS–formatted versions of the bts–#.cdf and cbsc–#.cdf
files on the diskette by entering the following command:
unix2dos /floppy/no_name/
(e.g., unix2dos bts–248.cdf /floppy/no_name/bts–248.cdf).
NOTE
Other versions of Unix do not support the unix2dos and dos2unix commands. In these cases,
use the Unix cp (copy) command. The copied files will be difficult to read with a DOS or
Windows text editor because Unix files do not contain line feed characters. Editing copied CDF
files on the LMF computer is, therefore, not recommended.
Using cp, multiple files can be copied in one operation by separating each filename to be copied
with a space and ensuring the destination directory (floppy/no_name) is listed at the end of the
command string following a space (e.g., cp bts–248.cdf cbsc–6.cdf /floppy/na_name)
Repeat steps 5 through 7 for each bts–# that must be supported by the LMF.
When all required files have been copied to the diskette, type eject and press the key.
10
Remove the diskette from the CBSC.
AT THE LMF:
11
Start the Windows operating system.
12
Insert the diskette into the LMF.
13
Using Windows Explorer (or equivalent program), create a corresponding bts–# folder in the
wlmf\cdma directory for each bts–#.cdf/cbsc–#.cdf file pair copied from the CBSC.
14
Use Windows Explorer (or equivalent program) to transfer the cbsc–#.cdf and bts–#.cdf files from
the diskette to the corresponding wlmf\cdma\bts–# folders created in step 13.
Creating a Named
HyperTerminal Connection for
MMI Connection
Confirming or changing the configuration data of certain BTS Field
Replaceable Units (FRUs) requires establishing an MMI communication
session between the LMF and the FRU. Using features of the Windows
operating system, the connection properties for an MMI session can be
saved on the LMF computer as a named Windows HyperTerminal
connection. This eliminates the need for setting up connection
parameters each time an MMI session is required to support
optimization.

Logging into a BTS
Logging into a BTS establishes a communications link between the BTS
and the CDMA LMF. You may be logged into one or more BTS’s at a
time, but only one LMF may be logged into each BTS.
IMPORTANT
Be sure that the correct bts–#.cdf and cbsc–#.cdf file is
used for the BTS. These should be the CDF files that are
provided for the BTS by the CBSC. Failure to use the
correct CDF files can result in wrong results. Failure to
use the correct CDF files to log into a live (traffic
carrying) site can shut down the site.
Before attempting to log into the BTS, confirm the LMF is properly
connected to the BTS (see Figure 3-2). Follow the procedure in
Table 3-9 to log into a BTS.
Prerequisites
Before attempting to login to a BTS, ensure the following have been
completed:
A bts-nnn folder with the correct CDF file and CBSC file exists.
The LMF is correctly installed and prepared, and the LMF computer
was connected to the BTS before starting the Windows operating
system and LMF software. If necessary, restart the computer after
connecting it to the BTS (see Table 3-2 and Figure 3-2).
Table 3-9: BTS Login Procedure

Download the BTS
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 (e.g.,
Release 8.x ROM code and Release 9.x 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
the correct hardware bin number. Code can be automatically or manually
selected.
The following are the devices to be downloaded:

– Master Group Line Interface (MGLI2)
– Slave Group Line Interface (SGLI2)
Clock Synchronization Module (CSM)
Multi Channel Card (MCC24 or MCC8E)
Broadband Transceiver (BBX2)
Test Subscriber Interface Card (TSIC) – if RFDS is installed
IMPORTANT
The MGLI must be successfully downloaded with code and
data, and put INS before downloading any other device.
The download code process for an MGLI automatically
downloads data and enables the MGLI before downloading
other devices. The other devices can be downloaded in any
order.
Follow the procedure in Table 3-11 to download the firmware
application code for the MGLI2. The download code action downloads
data and also enables the MGLI2.

WARNING
R9 RAM code must NOT be downloaded to a device that
has R8 ROM code and R8 RAM code must NOT be
downloaded to a device that has R9 ROM code. All
devices in a BTS must have the same R–level ROM and
RAM code before the optimization and ATP procedures
can be performed. If a newly installed R8 BTS is to be
upgraded to R9, the optimization and ATPs should be
accomplished with the R8 code. Then the site should be
upgraded to R9 by the CBSC. The optimization and ATP
procedures do not have to be performed again after the R9
upgrade. If a replacement R8 device needs to be used in a
R9 BTS, the device ROM code can be changed with use of
the LMF before the optimization and ATPs are performed
for the BTS. Refer to the Download ROM Code section. A

Enable CSMs
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 Low
Frequency Receiver (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.
IMPORTANT
– 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
status function to determine the current code load
versions.
– For n0n–RGPS sites only, verify the CSM configured
with the GPS receiver “daughter board” is installed in
the CSM–1 slot before continuing.
– The CSM(s) and MCC(s) to be enabled must have
been downloaded with code (Yellow, OOS–RAM)

FAIL may be shown in the status table for enable action. If Waiting For Phase Lock is shown in
the Description field, the CSM changes to the enabled state after phase lock is achieved. CSM 1
houses the GPS receiver. The enable sequence can take up to one hour to complete.
* 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.)
NOTE
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).
If more than an hour has passed, refer to Table 3-18 and Table 3-19 to determine the cause.

CSM System Time/GPS and LFR/HSO Verification
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 3-18). 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 3-31 illustrates the location of the boards in the BTS
frame. The diagram also shows the CSM front panel.

CSM System Time/GPS and LFR/HSO Verification – continued
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 3-17).
HSO, HSO2, and HSOX use the same source code in source selection
(see Table 3-17).
NOTE
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.
Front Panel LEDs
The status of the LEDs on the CSM boards are as follows:
Steady Green – Master CSM locked to GPS or LFR (INS).
Rapidly Flashing Green – Standby CSM locked to GPS or LFR
(STBY).
Flashing Green/Rapidly Flashing Red – CSM OOS–RAM attempting
to lock on GPS signal.
Rapidly Flashing Green and Red – Alarm condition exists. Trouble
Notifications (TNs) are currently being reported to the GLI.

LFR Initialization/Verification
The Low Frequency LORAN–C Receiver (LFR) is a full size card that
resides in the C–CCP Shelf. The LFR is a completely self-contained unit
that interfaces with the CSM via a serial communications link. The CSM
handles the overall configuration and status monitoring functions of the
LFR.
The LFR receives a 100 kHz, 35 kHz BW signal from up to 40 stations
(8 chains) simultaneously and provides the following major functions:
Automatic antenna pre-amplifier calibration (using a second
differential pair between LFR and LFR antenna)
A 1 second ±200 ηs strobe to the CSM
If the BTS is equipped with an LFR, follow the procedure in Table 3-19
to initialize the LFR and verify proper operation as a backup source for
the GPS.
NOTE
If CSMRefSrc2 = 2 in the CDF file, the BTS is equipped
with an LFR. If CSMRefSrc2 = 18, the BTS is equipped
with an HSO.

CSM System Time/GPS and LFR/HSO Verification – continued
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:
Reference oscillator temperature and phase lock monitor circuitry
Generates a highly stable 10 MHz sine wave.
Reference 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
The LMF is not logged into the BTS.
The COM1 port is connected to the MMI port of the primary CSM via
a null modem board.
The 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 3-20
to configure the HSO.
Table 3-20: HSO Initialization/Verification
Step
Action
At 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.
On the LMF at the CSM> prompt, enter sources .

Test Equipment Setup
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:
LMF
Test set
Directional coupler and attenuator
RF cables and connectors
Refer to Table 3-21 for an overview of connections for test equipment
currently supported by the LMF. In addition, see the following figures:
Figure 3-11 and Figure 3-12 show the test set connections for TX
calibration.
Figure 3-13 and Figure 3-14 show the test set connections for
optimization/ATP tests.
Figure 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:
CyberTest
Advantest R3465 and HP 437B or Gigatronics Power Meter
Hewlett–Packard HP 8935
Hewlett–Packard HP 8921 (W/CDMA and PCS Interface for
1.7/1.9 GHz) and HP 437B or Gigatronics Power Meter
Spectrum Analyzer (HP8594E) – optional
Rubidium Standard Timebase – optional
CAUTION
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
IMPORTANT
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.)
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.
WARNING
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
Background
Proper test equipment calibration ensures that the test equipment and
associated test cables do not introduce measurement errors, and that
measurements are correct.
NOTE
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.)
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.
CAUTION
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.
IMPORTANT
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.
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:
Measuring 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.
The 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.

Bay Level Offset Calibration
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
(BBX2 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 BBX2.
For starter frames, each receive path starts at a BTS RX antenna port and
terminates at a backplane BBX2 slot. Each transmit path starts at a
BBX2 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 BBX2 slot of the expansion frame.
The transmit path starts at a BBX2 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
(BBX2 slot) at the BTS site and stores that value in a BLO database.
Each transmit path starts at a C–CCP shelf backplane BBX2 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, BBX2 slots 1 and 13 (redundant) are tested. At sector
sites, BBX2 slots 1 through 12, and 13 (redundant) are tested. Only
those slots (sectors) actually equipped in the current CDF are tested,
regardless of physical BBX2 board installation in the slot.
When to Calibrate BLOs
Calibration of BLOs is required:
After initial BTS installation
Once each year
After replacing any of the following components or associated
interconnecting RF cabling:
– BBX2 board
– C–CCP shelf
– CIO card
– CIO to LPA backplane RF cable
– LPA backplane

– LPA
– TX filter / TX filter combiner
– TX thru-port cable to the top of frame
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.
WARNING
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.
CAUTION
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.
IMPORTANT
3-60
At new site installations, to facilitate the complete test of
each CCP shelf (if the shelf is not already fully populated
with BBX2 boards), move BBX2 boards from shelves
currently not under test and install them into the empty
BBX2 slots of the shelf currently being tested to insure that
all BBX2 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 BBX2 slots are equipped. Edit the file as
required to include BBX2 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 BBX2s using the
Download BLO function. An explanation of the file is shown below.
NOTE
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.
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 BBX2 slots. Slot 20
contains the calibration data for the redundant BBX2. Each BBX2 slot
header block contains:
A creation Date and Time – broken down into separate parameters of
createMonth, createDay, createYear, createHour, and createMin.
The 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.
The calibration data for a BBX2 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:

Ten calibration points per sector are supported for each branch. Two
entries are required for each calibration point.
The first value (all odd entries) refer to the CDMA channel
(frequency) the BLO is measured at. The second value (all even
entries) is the power set level. The valid range for PwrLvlAdj is from
2500 to 27500 (2500 corresponds to –125 dBm and 27500
corresponds to +125 dBm).

The 20 calibration entries for each sector/branch combination must be
stored in order of increasing frequency. If less than 10 points
(frequencies) are calibrated, the largest frequency that is calibrated is
repeated to fill out the 10 points.
Example:
C[1]=384,
odd cal entry
= 1 ‘‘calibration point”
C[2]=19102, even cal entry
C[3]=777,
C[4]=19086,
C[19]=777,
C[20]=19086, (since only two cal points were calibrated this
would be repeated for the next 8 points)
When the BBX2 is loaded with image = data, the cal file data for the
BBX2 is downloaded to the device in the order it is stored in the cal
file. TxCal data is sent first, C[1] – C[240]. Sector 1’s ten calibration
points are sent (C[1] – C[20]) followed by sector 2’s ten calibration
points (C[21] – C[40]), etc. The RxCal data is sent next (C[241] –
C[480]), followed by the RxDCal data (C[481] – C[720]).
Temperature compensation data is also stored in the cal file for each
set.

Bay Level Offset Calibration – continued
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 BBX2, 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 BBX2 (located
under the ParentSECTOR field of the ParentCARRIER CDF file
parameter).
NOTE
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.
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.
At 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 BBX2 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 BBX2 output level.
Example: 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

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

BTS Alarms Testing
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 3-19). 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 3-20). 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:
The 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 key (for
individual selections) or key (for a range of selections) while
clicking on the desired levels.
The 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.
The Clear button clears the Alarm Monitor display. New alarms that
occur after the Clear button is clicked are displayed.
The 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.

Automated Acceptance Test Procedures – All–inclusive TX & RX
Introduction
The Automated Acceptance Test Procedure (ATP) allows Cellular Field
Engineers (CFEs) to run automated acceptance tests on all equipped BTS
subsystem devices using the Local Maintenance Facility (LMF) and
supported test equipment per the current Cell Site Data File (CDF)
assignment.
The results of these tests (at the option of the operator) are written to a
file that can be printed. All tests are controlled from the LMF platform
using the GPIB interface, therefore, only recommended test equipment
supported by the LMF can be used.
IMPORTANT
Before performing any tests, use an editor to view the
“CAVEATS” section of the “readme.txt” file in the c:\wlmf
folder for any applicable information.
The ATP test is to be performed on out-of-service (OOS)
sectors only.
DO NOT substitute test equipment not supported by the
LMF.
NOTE
Refer to Chapter 3 for detailed information on test set
connections for calibrating equipment, cables and other test
set components, if required.
Customer requirements determine which ATP tests to are to be
performed and the craftsperson selects the appropriate ATP tests to run.
The tests can be run individually or as one of the following groups:
All TX: TX tests verify the performance of the BTS transmit line up.
These include the GLI, MCC, BBX2, and CIO cards, the LPAs and
passive components including splitters, combiners, bandpass filter,
and RF cables.
All RX: RX tests verify the performance of the BTS receiver line up.
These includes the MPC (for starter frames), EMPC (for expansion
frames), CIO, BBX2, MCC, and GLI cards and the passive
components including RX filter (starter frame only), and RF cables.
All TX/RX: Executes all the TX and RX tests.
Full Optimization: Executes the TX calibration, downloads the BLO,
and executes the TX audit before running all of the TX and RX tests.

ATP Test Prerequisites
Before attempting to run any ATP tests, ensure the following have been
completed:
BTS has been optimized and calibrated (see Chapter 3).
LMF is logged into the BTS.
CSMs, GLIs, BBX2s, MCCs, and TSU (if the RFDS is installed) have
correct code load and data load.
Primary CSM, GLI, and MCCs are INS_ACT.
BBX2s are calibrated and BLOs are downloaded.
BBX2s are OOS_RAM.
Test cables are calibrated.
Test equipment is connected for ATP tests (see Figure 3-13 through
Figure 3-16 starting on page 3-45).
Test equipment has been warmed up 60 minutes and calibrated.
GPIB is on.
WARNING
Before the FER is run, be sure that all LPAs are turned
OFF (circuit breakers pulled) or that all transmitter ports
are properly terminated.
All transmit ports must be properly terminated for all ATP
tests.
Failure to observe these warnings may result in bodily
injury or equipment damage.
TX OUT Connection
IMPORTANT
4-2
Many of the acceptance test procedures require taking
measurements at the TX OUT (BTS/RFDS) connector. At
sites without RFDS installed, all measurements will be via
the BTS TX OUT connector. At sites with RFDS installed,
all measurements will be via the RFDS directional coupler
TX OUT connector.

TX Output Acceptance Tests: Introduction
Individual Acceptance Tests
The following individual ATP tests can be used to verify the results of
specific tests.
Spectral Purity TX Mask (Primary & Redundant BBX2)
This test verifies that the transmitted CDMA carrier waveform generated
on each sector meets the transmit spectral mask specification with
respect to the assigned CDF file values.
Waveform Quality (rho)
This test verifies that the transmitted Pilot channel element digital
waveform quality (rho) exceeds the minimum specified value in
ANSI–J_STD–019. “Rho” represents the correlation between actual and
perfect CDMA modulation spectrum. A rho value of 1.0000 represents
100% (or perfect correlation).
Pilot Time Offset
The Pilot Time Offset is the difference between the CDMA analyzer
measurement interval (based on the BTS system time reference) and the
incoming block of transmitted data from the BTS (Pilot only, Pilot
Gain = 262, PN Offset = 0).
Code Domain Power (Primary & Redundant BBX2)
This test verifies the code domain power levels, which have been set for
all ODD numbered Walsh channels, using the OCNS command. This is
done by verifying that the ratio of PILOT divided by OCNS is equal to
10.2 + 2 dB, and, that the noise floor of all EVEN numbered “OFF”
Walsh channels measures < –27 dB (with respect to total CDMA channel
power).
Frame Error Rate
The Frame Error Rate (FER) test verifies RX operation of the entire
CDMA Reverse Link using all equipped MCCs assigned to all
respective sector/antennas. This test verifies the BTS sensitivity on all
traffic channel elements currently configured on all equipped MCCs at
an RF input level of –122 dBm (or –116 dBm if using TMPC).

TX Spectral Purity Transmit Mask Acceptance Test
Tx Mask Test
This test verifies the spectral purity of each BBX carrier keyed up at a
specific frequency, per the current CDF file assignment. All tests are
performed using the external calibrated test set, controlled by the same
command. All measurements are via the appropriate TX OUT
(BTS/RFDS) connector.
The Pilot Gain is set to 541 for each antenna and all channel elements
from the MCCs are forward-link disabled. The BBX is keyed up, using
both bbxlvl and bay level offsets, to generate a CDMA carrier (with pilot
channel element only). BBX power output is set to obtain +40 dBm as
measured at the TX OUT connector (on either the BTS or RFDS
directional coupler).
NOTE
TX output power is set to +40 dBm by setting BTS power
level to +33.5 dBm to compensate for 6.5 dB increase from
pilot gain set to 541.
The calibrated communications test set measures and returns the
attenuation level of all spurious and IM products in a 30 kHz resolution
bandwidth. With respect to the mean power of the CDMA channel
measured in a 1.23 MHz bandwidth in dB, verify that results meet
system tolerances at the following test points:
1.7/1.9 GHz:
– at least –45 dB @ + 900 kHz from center frequency
– at least –45 dB @ – 900 kHz from center frequency
800 MHz:

at least –45 dB @ + 750 kHz from center frequencY
at least –45 dB @ – 750 kHz from center frequency
at least –60 dB @ – 1980 kHz from center frequency
at least –60 dB @ – 1980 kHz from center frequency
The BBX2 then de-keys, and, if selected, the MCC is re-configured to
assign the applicable redundant BBX2 to the current TX antenna path
under test. The test is then repeated.

TX Waveform Quality (rho) Acceptance Test
Rho Test
This test verifies the transmitted Pilot channel element digital waveform
quality of each BBX carrier keyed up at a specific frequency per the
current CDF file assignment. All tests are performed using the external
calibrated test set controlled by the same command. All measurements
are via the appropriate TX OUT (BTS/RFDS) connector.
The Pilot Gain is set to 262 for each antenna, and all channel elements
from the MCCs are forward link disabled. The BBX2 is keyed up using
both bbxlvl and bay level offsets, to generate a CDMA carrier (with pilot
channel element only, Walsh code 0). BBX2 power output is set to 40
dBm as measured at the TX OUT connector (on either the BTS or
RFDS directional coupler).
The calibrated communications test set measures and returns the Pilot
channel element digital waveform quality (rho) in dB, verifying that
result meets system tolerances:
Waveform quality (rho) should be > 0.912 (–0.4 dB).
The BBX then de-keys and, if selected, the MCC is re-configured to
assign the applicable redundant BBX2 to the current TX antenna path
under test. The test is then be repeated.

TX Pilot Time Offset Acceptance Test
Pilot Offset Acceptance Test
This test verifies the transmitted Pilot channel element Pilot Time Offset
of each BBX carrier keyed up at a specific frequency per the current
CDF file assignment. All tests are performed using the external
calibrated test set controlled by the same command. All measurements
are via the appropriate TX OUT (BTS/RFDS) connector.
The Pilot Gain is set to 262 for each antenna and all TCH elements from
the MCCs are forward link disabled. The BBX is keyed up using both
bbxlvl and bay level offsets, to generate a CDMA carrier (with pilot
channel element only, Walsh code 0). BBX power output is set to 40
dBm as measured at the TX OUT connector (on either the BTS or
RFDS directional coupler).
The calibrated communications test set measures and returns the Pilot
Time Offset in us, verifying results meet system tolerances:
Pilot Time Offset should be within < 3 µs of the target PT
Offset (0 s).
The BBX then de-keys, and if selected, the MCC is re-configured to
assign the applicable redundant BBX to the current TX antenna path
under test. The test is then repeated.

TX Code Domain Power Acceptance Test
Code Domain Power Test
This test verifies the Code Domain Power/Noise of each BBX2 carrier
keyed up at a specific frequency per the current CDF file assignment.
All tests are performed using the external calibrated test set controlled by
the same command. All measurements are via the appropriate TX OUT
(BTS/RFDS) connector.
For each sector/antenna under test, the Pilot Gain is set to 262 and all
MCC channel elements under test are configured to generate Orthogonal
Channel Noise Source (OCNS) on different odd Walsh codes, and be
assigned a full–rate gain of 81. The maximum number of MCC/CEs to
be tested an any one time is 32 (32 odd Walsh codes). If more than 32
CEs exist, then multiple sets of measurements are made, so all channel
elements are verified on all sectors.
BBX2 power output is set to 40 dBm as measured at the TX OUT
connector (on either the BTS or RFDS directional coupler).
You verify the code domain power levels, which have been set for all
ODD numbered Walsh channels, using the OCNS command. This is
done by verifying that Pilot Power (dBm) minus OCNS Power (dBm) is
equal to 10.2 + 2 dB and that the noise floor of all “OFF” Walsh channels
measures < –27 dB (with respect to total CDMA channel power).
The BBX2 then de-keys and, if selected, the MCC is re-configured to
assign the applicable redundant BBX2 to the current TX antenna path
under test. The test is then repeated. Upon completion of the test, OCNS
is disabled on the specified MCC/CE.

RX Frame Error Rate (FER) Acceptance Test
FER Test
This test verifies the BTS FER on all traffic channel elements currently
configured on all equipped MCCs (full rate at 1% FER) at an RF input
level of –122 dBm [or –116 dBm if using Tower Top Amplifier
(TMPC)]. All tests are performed using the external calibrated test set as
the signal source controlled by the same command. All measurements
are via the LMF.
The pilot gain is set to 262 for each TX antenna and all channel elements
from the MCCs are forward-link disabled. The BBX2 is keyed up using
only bbxlvl level offsets, to generate a CDMA carrier (with pilot channel
element only). BBX2 power output is set to –20 dBm as measured at the
TX OUT connector (on either the BTS or RFDS directional coupler).
BBX2 must be keyed in order to enable the RX receive circuitry.
The LMF prompts the MCC/CE under test to measure all zero longcode
and provide the FER report on the selected active MCC on the reverse
link for both the main and diversity RX antenna paths, verifying that
results meet the following specification:
FER returned less than 1% and total frames measured is 1500
All MCC/CEs selected are tested on the specified RX antenna path. The
BBX then de-keys and, if selected, the MCC is re-configured to assign
the applicable redundant BBX to the current RX antenna paths under
test. The test is then repeated.
