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.
As the Code Division Multiple Access (CDMA) Local

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 CDMA Channel Processor (C–CCP) backplane Broad
Band Transceiver (BBX) 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 BBX slot
in the C–CCP shelf.
The TX path starts at the BBX, 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.

DRAFT
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 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, 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.
1
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.

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 sametechnical 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
Test Cable Calibration
Equipment Warm–up
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.
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.
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 RFDS
calibration procedures.

BTS Equipment Identification
Equipment Overview
The Motorola SC 4812T BTS can consist of the following equipment
frames:
– +27 V BTS (see Figure 1-2)
––48 V BTS (see Figure 1-3)
– +27 V BTS (see Figure 1-4)
––48 V BTS (see Figure 1-5)
NOTE
Logical BTS
Equipment listed below can be wall mounted or mounted
in a standard 19 inch frame. The description assumes that
all equipment is mounted in a frame for clarity.
If equipped with the RFDS option, the RFDS and directional couplers
are the interface between the site antennas and the BTS or Modem
frame. The RFDS equipment includes:
Directional couplers
Site receive bandpass/bandreject filters
RFDS
The BTS software implements the logical BTS capability. 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.
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 1-1 and Table 1-2 for specific C–CCP Shelf Device ID numbers.
Table 1-1: C–CCP Shelf/Cage Card/Module Device ID Numbers (Top Shelf)
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 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 1-3
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.
