NOTE
FCC Part 68
Mar 2001 xv
SCt4812T CDMA BTS Optimization/ATP DRAFT
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.

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:
SThe 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.
As the Code Division Multiple Access (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.
IMPORTANT
*
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:
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 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.
SThe 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.
SThe 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.

SCt4812T CDMA BTS Optimization/ATP DRAFT
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.
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
Refer to Appendix C for detailed basic guideline tables and
detailed Optimization/ATP Test Matrix outlining the
minimum tests that must be performed anytime a BTS
subassembly or RF cable associated with it is replaced.

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.
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.
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 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 RFDS
calibration procedures.

BTS Equipment Identification
Mar 2001 1-13
SCt4812T CDMA BTS Optimization/ATP DRAFT
Equipment Overview
The Motorola SC 4812T BTS can consist of the following equipment
frames:
SAt least one BTS starter frame
–+27 V BTS (see Figure 1-2)
––48 V BTS (see Figure 1-3)
SAncillary equipment frame (or wall mounted equipment)
SExpansion frames
–+27 V BTS (see Figure 1-4)
––48 V BTS (see Figure 1-5)
Ancillary Equipment Frame
Identification
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.
NOTE
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:
SDirectional couplers
SSite receive bandpass/bandreject filters
SRFDS
Logical BTS
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.

No adjacent carriers may exist within the same TX filter
combiner. “Adjacent” is defined as fc1 and fc2 being
1.25 MHz apart (center–to–center). “Non–adjacent” is
defined as fc1 and fc2 being >2.50 MHz apart
(center–to–center).

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.
