Jan 2002 xvii
SCt4812ET BTS Optimization/ATP — CDMA LMF
FCC Part 68 Requirements
This equipment complies with Part 68 of the Federal Communications
Commission (FCC) Rules and regulations. A label inside the cabinet
frame easily visible with the door open in the upper portion of the
cabinet contains, among other information, the FCC Registration
Number and Ringer Equivalence Number (REN) for this equipment. If
requested, this information must be provided to the telephone company.
The REN is useful to determine the quantity of the devices which may
connect to the telephone line. Excessive RENs on the telephone line may
result in the devices not ringing in response to incoming calls. In most,
but not all areas, the sum of the RENs should not exceed five (5.0). To
be certain of the number of devices that may be connected to the line as
determined by the total RENs, contact the telephone company to
determine the maximum REN for the calling area.
If the dial–in site access modem causes harm to the telephone network,
the telephone company will notify you in advance that temporary
discontinuance of service may be required. If advance notice is not
practical, the telephone company will notify you of the discontinuance as
soon as possible. Also, you will be advised of your right to file a
complaint with the FCC if you believe it is necessary.
The telephone company may make changes in its facilities, equipment,
operations, or procedures that could affect the operation of your dial–in
site access modem. If this happens, the telephone company will provide
advance notice so that you can modify your equipment as required to
maintain uninterrupted service.

CDMA LMF Product Description
The Code Division Multiple Access (CDMA) LMF is a graphical user
interface (GUI) based LMF. This product is specifically designed to
provide cellular communications field personnel the vehicle to support
the following CDMA BTS operations:
SInstallation
SMaintenance
SCalibration
SOptimization
The LMF also provides Command Line Interface (CLI) capability.
Activate the CLI by clicking on a shortcut icon on the desktop. The CLI
cannot be launched from the GUI, only from the desktop icon.
Online Help
Task oriented online help is available in the LMF by clicking on Help
from the menu bar.
Why Optimize?
Proper optimization and calibration assures:
SAccurate downlink RF power levels are transmitted from the site.
SAccurate 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.
SThe RX path starts at the ancillary equipment frame RFDS RX
directional coupler antenna feedline port, through the RX input port
on the rear of the frame, through the DDRCs, Multicoupler Preselector
Card (MPC), and additional splitter circuitry, ending at a CDMA
Channel Processor (C–CCP) backplane Broad Band Transceiver
(BBX) slot in the C–CCP shelf.
SA transmit path starts at the BBX, through the C–CCP backplane slot,
travels through the LPA/Combiner TX Filter and ends at the rear of
the input/output (I/O) Panel. 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.

SCt4812ET BTS Optimization/ATP — CDMA LMF
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 BBX board is optimized to a specific RX and TX
antenna port. (One BBX board acts in a redundant capacity for BBXs
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, the BTS must be prepared for operation.
This preparation includes verifying hardware installation, initial power
up, and GPS verification. Basic alarm tests are also addressed.
A calibration audit of all RF transmit paths is performed to verify factory
calibration.
A series of 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
Verify repair(s) made to the BTS by consulting an Optimization/ATP
Test Matrix table. This table outlines the specific tests that must be
performed anytime a BTS subassembly or RF cable associated with it is
replaced.
Refer to Appendix B for detailed basic guideline tables and
detailed Optimization/ATP Test Matrix.

NOTE
Required Test Equipment
To ensure consistent, reliable, and repeatable optimization test results,
test equipment meeting the following technical criteria should be used to
optimize the BTS equipment. You can, of course, substitute test
equipment with other test equipment models supported by the LMF
meeting the same technical specifications.
During manual testing, you can substitute test equipment
with other test equipment models not supported by the
LMF, but those models must meet the same technical
specifications.
NOTE
The customer has the responsibility of accounting for any measurement
variances and/or additional losses/inaccuracies that can be introduced
as a result of these 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.

Sector Configuration
There are a number of ways to configure the BTS frame. Table 1-5
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.
Table 1-5: BTS Sector Configuration
Number of
carriers Number of
sectors Channel spacing Filter requirements
13 or 6 N/A Bandpass Filter, Cavity Combiner (2:1 or 4:1)
2 6 Non–adjacent Cavity Combiner (2:1 Only)
2 6 Adjacent Dual Band Pass Filter
2 3 Non–adjacent Cavity Combiner (2:1 or 4:1)
2 3 Adjacent Bandpass Filter
3,4 3 Non–adjacent Cavity Combiner (2:1 or 4:1)
3,4 3 Adjacent Cavity Combiner (2:1 Only)
The matrix in Table 1-6 shows a correlation between the various sector
configurations and BBX cards.
In Table 1-6, BBXs may be BBX2s or BBX–1Xs.
