FCC Part 68
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.
If you experience trouble with the dial–in site access modem, please
contact:
Motorola Cellular Service Center (MCSC)
1501 W. Shure Drive
Arlington Heights, Illinois 60004
Phone Number: (847) 632–5390
for repair and/or warranty information. If the trouble is causing harm to
the telephone network, the telephone company may request you to
disconnect the equipment from the network until the problem is solved.
You should not attempt to repair this equipment yourself. This
equipment contains no customer or user–serviceable parts.
Changes or modifications not expressly approved by Motorola could
void your authority to operate this equipment.

Optimization Overview
Scope of This Document
This document provides information pertaining to the optimization and
audit tests of Motorola SC 4812ET 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 Hardware Installation Manual
– 68P64114A22, which covers the physical “bolt down” of all SC series
equipment frames, and the specific cabling configurations.
Document Composition
This document covers the following major areas:
 Introduction, consisting of preliminary background information (such
as component and subassembly locations and frame layouts) to be
considered by the Cell Site Field Engineer (CFE) before optimization
or tests are performed.
 Preliminary Operations, consisting of cabinet power up and power
down procedures.
 Optimization/calibration, covering topics of Local Maintenance
Facility (LMF) connection to the BTS equipment, Global Positioning
System (GPS) Verification, test equipment setup, downloading all
BTS processor boards, RF path verification, Bay Level Offset (BLO)
calibration and calibration audit, and Radio Frequency Diagnostic
System (RFDS) calibration.
 Acceptance Test Procedures (ATPs), consisting of ATP tests executed
by the LMF and used to verify all major transmit (TX) and
receive (RX) performance characteristics on all BTS equipment.
 Preparing to leave the site, presents instructions on how to properly
exit customer site, ensure that all equipment is operating properly, and
all work is complete according to Motorola guidelines.
 Basic troubleshooting, consisting of procedures for installation,
calibration, transmit and receive tests, backplane problems, GPS
failures, and module connectors.
 Appendices contain pertinent Pseudorandom Noise (PN) Offset,
frequency programming, output power data tables, data sheets that are
filled out manually by the CFE at the site, and information on test
equipment preparation.

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:
Installation
Maintenance
Calibration
Optimization
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:
 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 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.
 A 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.

Optimization Overview – 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, 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.

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.
NOTE
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.
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.
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 RFDS
calibration procedures.

BTS Equipment Identification
Equipment Overview
The SC 4812ET BTS consists of an RF Cabinet that is an outdoor,
weatherized version of the SC 4812T. The RF cabinet is powered by
27 Vdc and each cabinet has the capability to support up to 4 carriers (at
3 sector) or 2 carriers (at 6 sector).
The RF Cabinet houses the fan modules, C–CCP, LPA modules, LPA
trunking backplane, Bandpass 2:1 & 4:1 Combiners, Duplexer/Receive
Filter/Directional Couplers (DRDC) and a DC Power distribution
assembly. The Power Cabinet (PC) provides +27 Vdc distribution and
battery backup for the SC 4812ET. The Power Cabinet houses batteries,
battery heaters, rectifiers, an AC Load Center (ACLC), a power
distribution assembly, and two duplexed GFCI convenience outlets.
Logical BTS
A logical BTS can consist of up to four SC 4812ET 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
CDF file that includes equippage information for all of the logical BTS
frames and their devices is required. A Centralized Base Station
Controller (CBSC) file that includes channel data for all of the logical
BTS fames is also required.
The first frame of a logical BTS has a –1 suffix (e.g., BTS–812–1) and
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 will only be one tab (e.g., FRAME–282–1) for BTS–282. If a
logical BTS has more than one frame, there will be a separate FRAME
tab for each frame (e.g. FRAME–438–1, FRAME–438–101, and
FRAME–438–202 for a BTS–438 that has all three frames). If an
RFDS is included in the CDF file, an RFDS tab (e.g., RFDS–438–1)
will be 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 1-3 and Table 1-4 for specific C–CCP Shelf Device ID numbers.

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.

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.
Cellsite Types
Sites are configured as 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.
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 and
MCC24E/MCC8E boards (per cage), and linear power amplifier
assignments are some of the equipage data included in the CDF.
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 bag it
was shipped in.
Initial Installation of
Boards/Modules
Table 2-1: Initial Installation of Boards/Modules
Step
Action
Refer to the site documentation and install all boards and modules into the appropriate shelves as
required. Verify they are NOT SEATED at this time.
As the actual site hardware is installed, record the serial number of each module on a “Serial Number
Checklist” in the site logbook.

Setting Frame C–CCP Shelf
Configuration Switch
If the frame is a Starter BTS, the backplane switch settings behind the
fan module should be set to the ON position (see Figure 2-1).
The switch setting must be verified and set before power is applied to the
BTS equipment.
