Pinging the BTS
For proper operation, the integrity of the Ethernet LAN A and B links
must be be verified. Figure 3-12 represents a typical BTS Ethernet
configuration for the SC4812ET Lite with an expansion frame. The
drawing depicts cabling and termination for both the A and B LANs.
Ping is a program that sends request packets to the LAN network
modules to get a response from the specified “target” module.
Follow the steps in Table 3-12 to ping each processor (on both LAN A
and LAN B) and verify LAN redundancy is working properly.
CAUTION
Always wear a conductive, high impedance wrist strap
while handling any circuit card/module to prevent damage
by Electro–Static Discharge (ESD).

Step
Action
If this is a first–time communication with a newly–installed frame or a GLI2 which has been replaced,
perform the procedure in Table 6-3 and then return to step 2.
Be sure uncabled LAN A and B IN and OUT connectors in the power entry compartment (rear of
frame – Figure 3-9 and Figure 3-12) are terminated with 50 Ω loads.
If it has not already been done, interface the LMF computer to the BTS (refer to Table 3-6 and
Figure 3-10.)
If it has not already been done, start a GUI LMF session and log into the BTS ( refer to Table 3-7).
In the power entry compartment, remove the 50Ω termination on the frame LAN B IN connector. The
CDMA LMF session should remain active. Replace the 50Ω terminator on the BTS frame LAN B IN
connector.
From the Windows desktop, click the Start button and select Run.
In the Open box, type ping and the GLI2 IP address (for example, ping 128.0.0.2).

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 CDMA LMF is NOT
routine maintenance or a normal part of the optimization process. It is
only done in unusual situations where the resident ROM code in the
device does not match the release level of the site operating software
AND the CBSC can not communicate with the BTS to perform the
download. An example would be a BTS loaded with Release 9.2
software where a GLI loaded with Release 2.8.1 ROM code must be
installed to replace a malfunctioning MGLI.
Before ROM code can be downloaded from the CDMA 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.
ROM code can be downloaded to a device that is in any state. After the
download is started, the device being downloaded will change to
OOS–ROM (blue). The device will remain OOS–ROM (blue) when the
download is completed. The same Revision–level RAM code must then
be downloaded to the device. For example, if Release 2.9.2.1.1 ROM
code is downloaded, Release 2.9.2.1.1 RAM code must be downloaded.
Procedures to load ROM code are located in Appendix G.
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 will be 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 that matches
the “NextLoad” parameter of the CDF file). 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 loaded will change to OOS-ROM
(blue). When the download is completed successfully, the device will
change to OOS-RAM (yellow). When code is downloaded to an MGLI
or GLI, the CDMA LMF automatically also downloads data and then
enables the MGLI. When enabled, the MGLI will change to INS (green).
For non–GLI devices, data must be downloaded after RAM code is
downloaded. To download data, the device state must be OOS–RAM
(yellow).

Download the BTS – continued
RAM code downloading requires a few minutes. After the download
starts, the non–GLI device being loaded changes to OOS–ROM (blue). If
the download is completed successfully, the non–GLI device changes to
OOS–RAM (yellow).
The devices to be loaded with RAM code and data are:
S Master Group Line Interface (MGLI2)
S Redundant GLI (GLI2)
S Clock Syncronization Module (CSM) (Only if new revision code must
be loaded)
S Multi Channel CDMA (MCC24 or MCC8E) card
S Broadband Transceiver (BBX2)
S RFDS Test Subscriber Interface Card (TSIC), if equipped
IMPORTANT
The MGLI must be successfully downloaded with RAM
code and data, and in INS (green) status before
downloading any other device. The RAM code download
process for an MGLI automatically downloads data and
then enables the MGLI.
Verify GLI ROM Code Loads
Devices should not be loaded with RAM code which is for a different
system release than the ROM code with which they are loaded. Before
downloading RAM code and data to the processor cards, follow the
procedure in Table 3-13 to verify the GLI devices are loaded with the
correct ROM code for the system release used by the BSS.
Table 3-13: Verify GLI ROM Code Loads
Step
Action
If it has not already been done, start a GUI LMF session and log into the BTS ( refer to Table 3-7).
Select all GLI devices by clicking on them, and select Device > Status from the menu bar.
In the status report window which opens, note the number in the ROM Ver column for each GLI2.
S The system release number will be the first two decimal divisions of the number; for example, the
number 2.15.0.0.3 would be for System Release 2.15, and 2.9.2.2.34 would be for System Release
2.9.
If the ROM code loaded in the GLIs is not for the correct system release, log out of the BTS,
disconnect the CDMA LMF computer, reconnect the span lines as described in Table 5-7, and have the
CBSC download the correct ROM code version to the BTS devices.
When the GLIs have the correct ROM load for the system release being used, be sure the span lines
are disabled as outlined in Table 3-4 and proceed to downloading RAM code and data.

Click on the OK button to close the status report window.
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 GPS receiver interfaced to CSM 1 is used as the primary timing
reference and synchronizes the entire cellular system. CSM 2 provides
clock syncronization back–up, but does not have a GPS receiver.
The BTS may be equipped with a LORAN–C Low Frequency Receiver
(LFR), a High Stability Oscillator (HSO), or external 10 MHz Rubidium
source which the CSM can use as a secondary timing reference. In all
cases, the CSM monitors and determines what reference to use at a given
time.
IMPORTANT
For RF–GPS, verify the CSM configured with the GPS
receiver “daughter board” is installed in the frame’s CSM 1
slot before continuing.
Follow the steps outlined in Table 3-17 to enable the CSMs installed in

* IMPORTANT
The GPS satellite system satellites are not in a geosynchronous orbit and are maintained and operated
by the United States Department of Defense (DOD). The DOD periodically alters satellite orbits;
therefore, satellite trajectories are subject to change. A GPS receiver that is INS contains an “almanac”
that is updated periodically to take these changes into account.
If a GPS receiver has not been updated for a number of weeks, it may take up to an hour for the GPS
receiver “almanac” to be updated.
Once updated, the GPS receiver must track at least four satellites and obtain (hold) a 3–D position fix
for a minimum of 45 seconds before the CSM will come in service. (In some cases, the GPS receiver
needs to track only one satellite, depending on accuracy mode set during the data load).
NOTE
S If equipped with two CSMs, CSM–1 should be bright green (INS–ACT) and CSM–2 should be
dark green(INS–STB)
S If more than an hour has passed, refer to CSM Verification, see Figure 3-13 and Table 3-20 to
determine the cause.
After the CSMs have been successfully enabled, be sure the PWR/ALM LEDs are steady green
(alternating green/red indicates the card is in an alarm state).
Enable MCCs
This procedure configures the MCC and sets the “tx fine adjust”
parameter. The “tx fine adjust” parameter is not a transmit gain setting,
but a timing adjustment that compensates for the processing delay in the
BTS (approximately 3 mS).
Follow the steps outlined in Table 3-18 to enable the MCCs installed in

CSM System Time – GPS & LFR/HSO Verification
Clock Synchronization
Manager (CSM) System Time
The primary function of the Clock Synchronization Manager (CSM)
cards is to maintain CDMA system time. The CSM card in SCCP shelf
slot CSM–1 is the primary timing source while the card in slot CSM–2
provides redundancy. The second generation CSM card (CSM2) 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. A CSM2 card can have a local GPS receiver daughter card to
support an RF–GPS signal.
Each CSM2 card features a temperature–stablized, crystal oscillator that
provides 19.6608 MHz clock, even second pulse, and 3 MHz reference
signals to the synchronization source selected from the following (refer
to Table 3-20 for source selection/verification procedures):
S GPS: local/RF–GPS or remote/R–GPS
S LORAN–C Low Frequency Receiver (LFR) or High Stability
Oscillator (HSO)
S External reference oscillator sources
CDMA Clock Distribution Cards (CCDs) buffer and distribute
even–second reference and 19.6608 MHz clock signals from the CSM
cards. CCD 1 is married to the card in slot CSM–1, and CCD 2 is
married to the card in slot CSM–2.
The BTS switches between the primary and redundant units (card slots
CSM–1 and CSM–2, respectively) upon failure or command. A failure
in CSM–1 or CCD 1 will cause the system to switch to the
CSM–2–CCD 2 redundant card pair.
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 in CSM–1. During normal operation, the card in
CSM–1 selects GPS as the primary timing source (Table 3-20). The
source selection can also be overridden via the CDMA LMF or by the
system software.
In addition to providing GPS synchronization to the LFR or HSO
back–up sources, synchronization between the primary and redundant
CSM–CCD pairs increases reliability.
Low Frequency Receiver/
High Stability Oscillator
The CSM performs 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

The LFR requires an active external antenna to receive LORAN–C RF
signals. Timing pulses are derived from this signal, which is

CSM System Time – GPS & LFR/HSO Verification – continued
synchronized to Universal Time Coordinates (UTC) and GPS time. The
LFR can maintain system time indefinately 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 (Table 3-20). HSO,
HSO2, and HSOX use the same source code in source selection
(Table 3-20).
NOTE
Allow the base site and test equipment to warm up for
60 minutes after any interruption in oscillator power. CSM
card warm-up allows the oscillator oven temperature and
oscillator frequency to stabilize prior to test. Test
equipment warm-up allows the Rubidium standard
timebase to stabilize in frequency before any measurements
are made.

Follow the steps outlined in Table 3-19 to set up test equipment.
Table 3-19: Test Equipment Setup (GPS & LFR/HSO Verification)
Step
1a
Action
For local GPS (RF–GPS): Verify a CSM card with a GPS receiver is installed in the primary CSM
slot, CSM–1, and that CSM–1 is INS.
NOTE
This is verified by checking the card ejectors for kit number SGLN1145 on the card in slot 1.
1b
For Remote GPS (RGPS): Verify a CSM2 card is installed in primary slot CSM–1 and that CSM–1 is
INS.
NOTE
This is verified by checking the card ejectors for kit number SGLN4132CC or subsequent.
Remove CSM–2 (if installed) and connect a serial cable from the LMF COM 1 port (via null modem
card) to the MMI port on CSM–1 (see Figure 3-13).
Reinstall CSM–2.
Start an MMI communication session with CSM–1 by using the Windows desktop shortcut icon (see
Table 3-11) .
When the terminal screen appears press the Enter key until the CSM> prompt appears.
CAUTION
In the power entry compartment, connect the GPS antenna
to the RF GPS connector ONLY. Damage to the GPS
antenna and/or receiver can result if the GPS antenna is
inadvertently connected to any other RF connector.

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.)
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 set–up ensures that all measurements are correct
and the test equipment and associated test cables do not introduce
measurement errors.
NOTE
If the test equipment set (see Chapter 1, Terms and
Abbreviations) being used to interface with the BTS has
been calibrated and maintained as a set, this procedure does
not need to be performed.
This procedure must be performed before the optimization. Verify all test
equipment (including all associated 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, the set must be re-calibrated. Failure to do so can
introduce measurement errors, resulting in incorrect
measurements and degradation to system performance.
Motorola recommends repeating cable calibration before
testing at each BTS site.
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
These procedures access the CDMA 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 equipment set. After
calibration, the gain/loss offset values are stored in a test measurement
offset file on the CDMA LMF.

Selecting Test Equipment
Prerequisites
A Serial Connection and a Network Connection tab are provided for
test equipment selection. The Serial Connection tab is used when the
test equipment items are connected directly to the CDMA LMF
computer via a GPIB box (normal setup). The Network Connection tab
is used when the test equipment is to be connected remotely via a
network connection.
Ensure the following has been completed before selecting test
equipment:
S Test equipment is correctly connected and turned on.
S Test equipment GPIB addresses have been verified as correct.
S CDMA LMF computer serial port and test equipment are connected to
the GPIB box.
Selecting Test Equipment
Use Options > LMF Options in the menu bar to select test equipment
automatically (using the autodetect feature) or manually.
Manually Selecting Test
Equipment in a Serial

Calibrating Cables – Overview
The cable calibration function is used to measure 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 steps.
S Measure the loss of a short cable. This is done to compensate for any
measurement error of the analyzer. The short cable, which is used only
for the calibration process, is used in series with both the TX and RX
cable configuration when they are measured. 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. This deduction is done so any error in the
analyzer measurement will be adjusted out of both the TX and RX
measurements.
S 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
the test equipment. For BTSs with antenna ports carrying duplexed TX
and RX, a directional coupler and, if required by BTS type, an
additional attenuator are also used on the RX cable configuration and
must be included in the measurement.
S The short cable plus the TX cable configuration loss is measured. The
TX cable configuration normally consists of two coax cables with
type–N connectors and a directional coupler, a load, and an additional
attenuator if required by the BTS type. The total loss of the path loss

Test Set Calibration – continued
of the TX cable configuration must be as required for the BTS
(normally 30 or 50 dB). The Motorola Cybertest analyzer is different
in that the required attenuation/load is built into the test set so the TX
cable configuration consists only of the required length coax cable.
Calibrating Cables with a
CDMA Analyzer
The Cable Calibration menu item from the Util menu list is used to
calibrate both TX and RX test cables for use with CDMA LMF.
NOTE
LMF cable calibration cannot be accomplished with an
HP8921A analyzer for 1.9 MHz. A different analyzer type
or the signal generator and spectrum analyzer method must
be used (refer to Table 3-27 and Table 3-28). Cable
calibration values must be manually entered if the signal
generator and spectrum analyzer method is used. For the
HP8921A, refer to Appendix F.
The test equipment must be selected before this procedure can be started.
Follow the procedure in Table 3-26 to calibrate the cables. Figure 3-14
illustrates the cable calibration test equipment setup.
Table 3-26: Cable Calibration
Step
Action
From the Util menu, select Cable Calibration. A Cable Calibration window is displayed.
Enter a channel number(s) in the Channels box. Multiple channels numbers must be separated with a
comma, no space (i.e., 200,800). When two or more channels numbers are entered, the cables will be
calibrated for each channel. Interpolation will be accomplished for other channels as required for TX
calibration.
Select TX and RX CABLE CAL, TX CABLE CAL or RX CABLE CAL in the Cable Calibration
picklist.
Click OK. Follow the directions displayed for each step. A status report window will be displayed
with the results of the cable calibration.

Use spectrum analyzer to measure signal generator output (see Figure 3-19, “A”) and record the value.
Connect the spectrum analyzer’s short cable to point “B”, as shown in the lower portion of the
diagram, to measure cable output at customer frequency (869.7–893.31 MHz band for North American
cellular and 1930–1990 MHz for North American PCS) and record the value at point “B”.
Calibration factor = A – B Example:
Cal = –1 dBm – (–53.5 dBm) = 52.5 dB
NOTE
The short cable is used for calibration only. It is not part of the final test setup. After calibration is
completed, do not re-arrange any cables. Use the equipment setup, as is, to ensure test procedures use

Bay Level Offset Calibration
Introduction
Calibration compensates for normal equipment variations within the
BTS and assures maximum measurement accuracy.
RF Path Bay Level Offset
Calibration
Bay Level Offset (BLO) calibration identifies the accumulated gain in
every transmit path (BBX2 slot) at the BTS site and stores that value in
the CDMA LMF CAL file. The BLOs are subsequently downloaded to
each BBX2.
Each transmit path starts at an SCCP shelf backplane BBX2 slot, travels
through the CIO card, trunking module, LPA, trunking module (again),
TX filter or TX filter combiner, DRDC or TRDC, and ends at a BTS TX
antenna port.
Each receive path starts at a BTS RX antenna port, travels through a
DRDC or TRDC, the MPC card, the CIO card, and terminates at a
backplane BBX2 slot.
Calibration identifies the accumulated gain in every transmit path ( by
BBX2 slot) at the BTS site and stores that value in the CAL file. When
the TX path calibration is performed, the RX path BLO will
automatically be set to the default value.
When to Calibrate BLOs
Calibration of BLOs is required after initial BTS installation.
The BLO data of an operational BTS site must be re-calibrated once
each year. Motorola recommends re-calibrating the BLO data for all
associated RF paths after replacing any of the following components or
associated interconnecting RF cabling:

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
At new site installations, to facilitate the complete test of
each SCCP 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).
RX Path Calibration
RX path calibration is not required or supported on CDMA BTS
systems. Default RX calibration values are written to the RX calibration
data files during the TX calibration routine. Functionality is verified
during Frame Erasure Rate (FER) testing.

BLO Calibration Data File
During the calibration process, the CDMA LMF creates a calibration
(CAL) data file where BLO values are stored. After calibration has been
completed, this offset data must be downloaded to the BBX2s using the
CDMA LMF Download BLO function. An explanation of the file is
shown below.
NOTE
Due to the size of the file, Motorola recommends printing
out a copy of a bts.cal file and referring to it for the
following descriptions.
The CAL file is subdivided into sections organized on a per–slot basis (a
slot Block).
The Slot 1 Block contains the calibration data for the six BBX2 slots.
The Slot 20 Block contains the calibration data for the redundant BBX2
(see Table 3-32). Each BBX2 slot Block header contains:
S A creation Date and Time – broken down into separate parameters of
createMonth, createDay, createYear, createHour, and createMin.
S The number of calibration entries – fixed at 720 entries corresponding
to 360 calibration points of the CAL file – plus the slot Block format.
Within the slot Block body, the BBX2 calibration data (BayLevelCal) is
organized as a large flat array. The array is organized by branch, BBX2
SCCP cage slot, and calibration point.
S 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:

S Refer to the CAL file print–out and Table 3-32. It can be seen that
there is one BBX2 slot per sector, and 10 calibration points for each
BBX2 (sector) are supported for each branch. Each “calibration point”
consists of two entries.
S The first entry for a calibration point (all odd entries) identifies the
CDMA channel (frequency) where the BLO is measured. The second
calibration point entry (all even entries) is the power set level
(PwrLvlAdj). The valid range for PwrLvlAdj is from 2500 to 27500
08/01/2001
PRELIMINARY 3-67
1X SCt4812ET Lite BTS Optimization/ATP
Bay Level Offset Calibration – continued
(2500 corresponds to –125 dBm and 27500 corresponds to +125
dBm).
S The 10 calibration points for each slot/branch combination must be
stored in order of increasing frequency. If less than 10 points
(frequencies) are calibrated, the BLO data for the highest frequency
calibrated is written into the remainder of the 10 points for that
slot/branch.
Example:
C[1]=384
(odd cal entry)
C[2]=19102
= 1 “calibration point”
(even cal entry)
C[3]=777
(odd cal entry)
C[4]=19086
(even cal entry)
C[19]=777
(odd cal entry)
C[20]=19086
(even cal entry)
In the example above, BLO was measured at only two frequencies
(channels 384 and 777) for SCCP slot BBX–1 transmit (Table 3-32).
The BLO data for the highest frequency measured (777) will be
written to the remaining eight transmit calibration points (defined by
entries C[5] through C[20]) for BBX2–1.
S When BLO data is downloaded to the BBXs, the data is downloaded
to the devices in the order it is stored in the CAL file. TxCal data
(C[1] – C[60]) is sent first. BBX2 slot 1’s 10 calibration points (C[1]
– C[20]) are sent initially, followed by BBX2 slot 2’s 10 calibration
points (C[21] – C[40]), and so on. The RxCal data is sent next,
followed by the RxDCal data.
S Temperature compensation data (TempLevelCal) is also stored in the
CAL file for each slot Block.

Table 3-33: Set Up Test Equipment (RF Path Calibration)
Step
Action
! CAUTION
To prevent damage to the test equipment, all transmit (TX) test connections must be via the 30 dB
directional coupler for 800 MHz or via a 30 dB coupler with a 20 dB in–line attenuator for 1900
MHz.
For TX path calibration, verify that the coaxial cable from the appropriate ANTENNA connector
(Figure 1-6 or Figure 1-7) is connected to the test equipment RF input port via the directional
coupler.
Transmit (TX) Path Calibration
The assigned channel frequency and desired power level at the frame TX
ports for transmit calibration are derived from the BTS CDF file. Each
BBX2 at the site is assigned to a sector and carrier. These are specified
respectively in the sector and carrier fields of the ParentCARRIER
parameter in each BBX2’s CDF file block. The channel frequency and
desired power for the assigned sector are specified respectively in the
ChannelList and SIFPilotPwr parameters of the CDF block for the
CARRIER to which the BBX2 is assigned.
The calibration procedure attempts to adjust the measured power to
within +0.5 dB of the desired power. The calibration will pass if the
error is less than +1.5 dB.
The TX BLO for the SC4812ET Lite is approximately 42.0 dB ±5.0 dB.
BLO is the gain in dB between the known power output of the BBX2
and the measured power at the TX port. BLO is derived by deducting the
known BBX2 power output from the power measured at the TX port or
(Measured Power) – (BBX2 TX Power Output).
Example:
Measured Power (at TX port) = 36.0 dBm
Known BBX TX Power Output = –6.0 dBm
BLO = (36.0) – (–6.0) = 42.0 dB gain
The CDMA LMF Tests menu list items TX Calibration and All
Cal/Audit perform TX BLO Calibration testing for installed BBX(s).
The All Cal/Audit menu item initiates a series of actions to perform TX
calibration, download BLO, and perform TX audit if the TX calibration
passes. The TX Calibration selection performs only the TX calibration.
When the TX Calibration selection is used, BLO download and TX
audit must be performed as separate activities. All measurements are
made through the appropriate antenna connector using the calibrated TX
cable setup.
In both the TX Calibration and All Cal/Audit dialog boxes, a Verify
BLO checkbox is provided and checked by default. After the actual TX
calibration is completed during either the TX Calibration or All
Cal/Audit process, the BLO derived from the calibration is compared to
a standard, acceptable BLO tolerance for the BTS. In some installations,
08/01/2001
PRELIMINARY 3-69
1X SCt4812ET Lite BTS Optimization/ATP
Bay Level Offset Calibration – continued
additional items may be installed in the transmit path. The additional
change in gain from these items could cause BLO verification failure
and, therefore, failure of the entire calibration. In these cases, either the
Verify BLO checkbox should be unchecked or the additional path losses
should be added into each applicable sector using the Util > Edit > TX
Coupler Loss... function.

RFDS Setup and Calibration – continued
RFDS Calibration
The RFDS Calibration option is used to calibrate 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
CDMA communications analyzer. The difference (offset) between the
RFDS keyed power level and 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.
For each RFDS TSIC, the channel frequency is determined at the lower
third and upper third of the appropriate band using the frequencies listed
in Table 3-44.

Automated Acceptance Test Procedure – Introduction
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 CDMA LMF GUI environment and
supported test equipment.
The operator can choose to save the results of these tests to a report file,
from which ATP reports are generated for later printout.
Perform the ATP test on out-of-service sectors or sites only. Because all
tests are controlled via the CDMA LMF computer using the GPIB
interface from the CDMA LMF computer, only recommended test
equipment supported by the CDMA LMF can be used.
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.
IMPORTANT
The ATP test is to be performed on out-of-service sectors
only.
DO NOT substitute test equipment with other models 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.
The CFE selects the appropriate ATP tests to run to satisfy customer and
regulatory requirements for verifying cell site performance. These tests
can be run individually or as one of the following groups:
S All TX: TX tests verify the performance of the BTS transmit
elements. These include the GLI2, MCC, BBX2, BDC, and trunking
modules, the LPAs, and passive components including splitters,
combiners, bandpass filter(s), and RF cables.
S All RX: RX tests verify the performance of the BTS receive elements.
These include the MPC (for starter frames), , BBX2, MCC, and GLI2
modules, and the passive components including RX filter (starter
frame only), and RF cables.
S All TX/RX: Executes all TX and RX tests.
S Full Optimization: Executes the TX calibration, downloads BLO,
and executes the TX audit before running all TX and RX tests.

WARNING
Before the FER is run, be sure that all LPAs are turned
OFF (circuit breakers pulled) or that all transmitter
connectors are properly terminated.
All transmit connectors must be properly terminated for all
ATP tests.
Failure to observe these warnings may result in bodily
injury or equipment damage.
TX/RX Antenna Connections
Refer to Figure 1-6 or Figure 1-7 for identification of the transmit and
receive antenna connections where measurement are to be taken.
Directional couplers for signal sampling by the RFDS, if installed, are
integral to the SC4812ET Lite transmit and receive paths in the DRDCs
and TRDCs. As a result, all ATP measurement connections are made at
the antenna connectors on the RF interface panel.

Individual Acceptance Tests–Introduction
Individual Acceptance Tests
The following individual ATP tests can be used to evaluate specific
aspects of BTS operation against individual performance requirements.
All testing is performed using the CDMA LMF GUI environment.
TX Testing
TX tests verify any given transmit antenna path and output power
control. All tests are performed using the external calibrated test set. All
measurements are via the appropriate TX OUT connector.
TX tests verify TX operation of the entire CDMA Forward Link using
all BBX2s assigned to all respective sector/antennas. Each BBX2 is
keyed up to generate a CDMA carrier (using both bbx level and bay
level offsets) at the CDF file carrier output power level (as specified in
the site documentation).
RX Testing
RX testing verifies any given receive antenna path. All tests are
performed using the external calibrated test set to inject a CDMA RF
carrier with all zero longcode at the specified RX frequency via the
appropriate RX IN connector.
RX tests verify RX operation of the entire CDMA Reverse Link using
all equipped MCCs assigned to all respective sector/antennas.
Individual Tests
Spectral Purity TX Mask
This test verifies that the transmitted CDMA carrier waveform generated
on each sector meets the transmit spectral mask specification (as defined
in IS–97) 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 IS–97.
Rho represents the correlation between the actual and perfect CDMA
modulation spectrums. 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, Walsh
code 0).
Code Domain Power/Noise Floor
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).
BTS Frame Error Rate
This test verifies the BTS receive Frame Error Rate (FER) on all Traffic
Channel elements currently configured on all equipped MCCs (fullrate at
one percent FER) at an RF input level of –119 dBm on the main RX
antenna paths using all equipped MCCs and BBX2s at the site. The
diversity RX antenna paths are also tested using the lowest equipped
MCC/CE ONLY.
NOTE
There are no pass/fail criteria associated with FER readings
taken at level below –119 dBm, other than to verify that
the FER measurement reflects changes in the RX input
signal level.

Removing External Test
Equipment
Perform the procedure in Table 5-3 to disconnect the test equipment and
configure the BTS for active service.
Table 5-3: Remove External Test Equipment
Step
Action
Disconnect all external test equipment from all TX and RX connectors at the rear of the frame.
Reconnect and visually inspect all TX and RX antenna feed lines at the frame RF interface panel.
! CAUTION
Verify that all sector antenna feed lines are connected to the correct ports on the frame. Crossed
antenna cables will cause system degradation of call processing.
Reset All Devices and Initialize
Site Remotely
Generally, devices in the BTS should not be left with data and code
loaded from the CDMA LMF. The configuration data and code loads
used for normal operation could be different from those stored in the
CDMA LMF files. By resetting all devices, the required data and code
can be loaded from the CBSC when spans are again active.
To reset all devices and have the OMCR/CBSC bring up the site
remotely, perform the procedure in Table 5-4.
Table 5-4: Reset BTS Devices and Remote Site Initialization
Step
Action
Terminate the CDMA LMF session by following the procedures in Table 5-6.
NOTE
In the following step, performing Table 2-6 DC voltage measurements other than those using the MAP
VOLT and AMP indicators is not necessary if DC power system components have not been replaced
during the optimization and/or ATP process.
Cycle BTS power off, as specified in Table 2-9, and on, as specified in Table 2-5, Table 2-6, and step 1
of Table 2-7, respectively.
Reconnect spans by following the procedure in Table 5-7.
Notify the OMCR/CBSC to take control of the site and download code and data to the BTS.
Verify the CBSC can communicate with the GLIs.
