avoid rough handling or jarring of the equipment. The CRT should be
handled only by qualified maintenance personnel, using approved safety
mask and gloves.
Do not substitute parts or
modify equipment
Because of the danger of introducing additional hazards, do not install
substitute parts or perform any unauthorized modification of equipment.
Contact Motorola Warranty and Repair for service and repair to ensure
that safety features are maintained.
Dangerous procedure
warnings
Warnings, such as the example below, precede potentially dangerous
procedures throughout this manual. Instructions contained in the
warnings must be followed. You should also employ all other safety
precautions that you deem necessary for the operation of the equipment

Physical Differences
This Read-me-first document describes a summary of changes between
the existing SC4812T 800MHz BTS and the SC4812T-MC
(Multicarrier) BTS. The SC4812T-MC is based on the existing
SC 4812T platform and employs similar hardware and architecture. The
differences between these products are briefly described and illustrated
below. This section is not intended to replace the SC4812T-MC manual
set. This information applies generally to both 800 MHz +27V and
–48V frames, although only +27V illustrations are shown.
Multicarrier provides the capability for all PAs in all quadrants to
provide trunked power across all sector/carriers. This differs from the
previous architecture in which PA modules within a quadrant provided
trunked power to only one carrier. Furthermore, in SC4812T-MC,
adjacent channels can be combined onto one antenna versus being
transmitted on separate antennas in SC4812T.
An overview of the BTS differences is illustrated in the following table
and in illustrations on the following pages (Figure 1-1 thru Figure 1-4).

Figure 1-4: PA Breaker Mapping Comparison
Each breaker controls a pair of PAs. In an SC4812T–MC,
opening (pulling) a PA breaker while the BTS is operating
will degrade the TX Output power of ALL sector–carriers,
not just a specific carrier as in an SC4812T.

General Test Procedural
Changes for SC 4812T-MC
The GENERAL information herein summarizes procedural
changes introduced with the SC 4812T–MC BTS. Detailed
procedures are provided in the Optimization and ATP
sections.
NOTE
1. During the execution of any TX tests or calibration
procedures, ALL Power Amplifiers (PA) must be in
service (INS).
2. When logging into a BTS with a system release earlier
than 2.16.4.x, be sure to set BTS type to MultiCarrier
in the dialog box which will appear when logging into
the BTS.
NOTE
Transmit (TX) Bay Level Offset (BLO) Specifications –
SC4812T–MC TX BLO specifications for different BTS sector
configurations are as follows:
S800 MHz Three–sector BTS:
– Single–sided BLO: >35dB
– Double–sided BLO: 40dB +/– 5dB
S800 MHz Six–sector BTS
– Single–sided BLO: >38dB
– Double–sided BLO: 43dB +/– 5dB
S1.9 GHz Three–sector BTS:
– Single–sided BLO: >30dB
– Double–sided BLO: 35dB +/– 5dB
S1.9 GHz Six–sector BTS
– Single–sided BLO: >33dB
– Double–sided BLO: 38dB +/– 5dB
Verifying Pilot Power Setting
with a Wide Band RF Power
Meter
The SC4812T–MC requires all equipped PAs be enabled during TX test.
With a “tuned” RF power meter, such as the Agilent VSA E4406A, all
sectors–carriers can be enabled simultaneously and each sector–carrier
power level setting can be measured. The following work–around
procedures are suggested when using a wide band RF power meter and
the BTS is under OMC–R control.
Read Me First SCE4812T–MC to SCE4812T Optimization/ATP – continued
5/21/04 1X SC4812T–MC BTS Optimization/ATP 1-5
DRAFT
This workaround is only required before system release
2.16.4.x. After release 2.16.4.x, any one BBX keyed will
enable all the CLPA modules.
NOTE
1–carrier configuration (requires 3 measurements) – The 1-carrier
procedure is identical to the current SC4812T, which is to enable all
three sector BBXs, then measure with each sector with the RF power
meter.
2–carrier configuration (requires 6 measurements) – The procedure
below allows taking measurements with both carriers enabled and more
than one carrier on same sector.
Sector Carrier 1 Carrier 2 Sector Carrier 1 Carrier 2
1 BBX-1 1 BBX-7
2 BBX-2 2 BBX-8
3 BBX-9 3 BBX-3
Procedure:
1. Enable BBX-1 (C1–S1), BBX-2 (C1–S2), and
BBX-9 (C2–S3).
2. Measure TX power from each of all 3 sectors.
3. Disable BBX-1, BBX-2, and BBX-9.
4. Enable BBX-3 (C1–S3), BBX-7 (C2–S1), and
BBX-8 (C2–S2).
5. Measure TX power from each of all 3 sectors.
6. Disable BBX-3, BBX-7, and BBX-8.

Purpose of Optimization
5/21/04 1X SC4812T–MC BTS Optimization/ATP 1-11
DRAFT
Why Optimize?
Proper optimization and calibration ensures that:
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. Site optimization guarantees that the combined
losses of the cables and the gain/loss characteristics and built-in
tolerances of each BTS frame do not accumulate and cause improper site
operation.
What Happens During
Optimization?
Overview – During optimization, the accumulated path loss or gain is
first determined for each RF transmit path in the BTS. These transmit
path loss or gain values are then stored in a database along with RF
receive path default values.
RF path defintions – For definitions of the BTS transmit (TX) and
receive (RX) paths, see “What is Bay Level Offset Calibration?” in the
Bay Level Offset Calibration section of Chapter 3.
In this publication, all models of the Broad Band
Transceiver (BBX) board usable in this BTS, are
generically identified as BBX, unless otherwise specified.
Also, all models of the Multi–Channel CDMA (MCC)
cards usable in this BTS, are generically identified as
MCC, unless otherwise specified.
NOTE
RF paths and transceiver optimization – Twelve of the BBX boards in
each Combined–CDMA Channel Processor (C–CCP) shelf are
optimized to specific RX and TX antenna connectors. The last BBX
board provides redundancy for BBX boards 1 through 12, and is
optimized to all antenna connectors. A single optimization value is
generated for each complete path. This eliminates the accumulation of
error that would occur from individually measuring and summing the
gain and loss of each element in the path.
Using RF path gain/loss values – BTS equipment factors in the derived
optimization values internally to adjust transceiver power levels, leaving
only site–specific antenna feedline loss and antenna gain characteristics
to be factored in by the CFE when determining required site Effective
Radiated Power (ERP) output power levels.

When to Optimize
1-12 1X SC4812T–MC BTS Optimization/ATP 5/21/04
DRAFT
New Installations
The following operations and optimization/test actions should be
accomplished for a new BTS or frame installation:
1. After the initial site installation, the BTS must be prepared for
operation. This preparation includes verifying hardware installation,
initial power–up, downloading of operating code, verifying GPS
operation, and verifying transmit and receive paths.
2. Next, the optimization is performed. Optimization includes
performance verification and calibration of all transmit and receive
RF paths, and download of accumulated calibration data.
3. A calibration audit of all RF transmit paths may be performed any
time after optimization to verify BTS calibration.
4. After optimization, a series of manual pre–Acceptance Test
Procedure (ATP) verification tests are performed to verify
alarm/redundancy performance.
5. After manual pre–ATP verification tests, an ATP is performed to
verify BTS performance. An ATP is also required to demonstrate
regulation compliance before the site can be placed in service.
Site Expansion
Optimization is also required after expansion of a site with additional
BTS frames.
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 a detailed FRU Optimization/ATP Test Matrix
outlining the minimum tests that must be performed any time a BTS RF
subassembly or cable associated with an RF path is replaced.

Test Equipment Selection, Calibration, and General Operation
Requirememnts

DRAFT
Policy
General Requirements – To ensure consistent, reliable, and repeatable
optimization test results, test equipment and software meeting the
following technical criteria should be used to optimize the BTS
equipment.
Test equipment substitution – Test equipment can, of course, be
substituted with other test equipment models but those models must
meet the same technical specifications. All test equipment models
selected for use in BTS calibration and acceptance testing must be
supported by the LMF..
Measurement variances and test equipment substitution – It is the
responsibility of the customer to account for any measurement variances
and/or additional losses/inaccuracies that can be introduced as a result
of test equipment model 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 and calibration prior to BTS optimization. Follow the original
equipment manufacturer (OEM) recommended maintenance and
calibration schedules closely.
Test Cable Calibration
On–site cable calibration – Test cables can make critical differences in
optimization accuracy. It is recommended that cable calibration be run at
every BTS with the complete test equipment set. This method
compensates for test cable insertion loss within the test equipment set
itself. No other allowance for test cable insertion loss needs to be made
during the performance of BTS calibration or acceptance tests.
In–shop cable characterization – Another method to account for cable
loss is by entering it into the LMF during the optimization procedure.
This method requires accurate test cable characterization using shop test
equipment. Characterized cables should be tagged with the
characterization information, and the measured losses entered into the
LMF before 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
procedures.

Integrated BTS Router A GLI3 card loaded with bootROM code which allows the card’s controller for
Concentration Interface Highway (CHI) bus 2 to function as a router for packet
traffic for the BTS. Employing IBRs permits converting a BTS to packet backhaul
operation without using an external BTS router group. IBRs can operate as
non–redundant or redundant BTS routers, but their employment limits BTS span
capacity to one span as opposed to four spans for external BTS routers.

configuration
The initial minimum configuration data which must be loaded into a BTS router
to enable it to communicate on the network. This standard “canned configuration”
is generated by a script included in the R16.1 software load for the
OMC–R/CBSC. Separate configuration files for the primary BTS router on each
FE LAN at a site is created by the script and can be copied to the Compact Flash
(CF) memory card containing the IOS for BTS routers. Once the CF card with the
IOS and minimum standard configuration is installed, the BTS router can
communicate with the OMC–IP and the full, site–specific router configuration file
can be downloaded from the Mobile Wireless Center to the router. Different
configuration files are required for circuit and packet backhaul operation.

Equipment Overview
The BTS can consist of the following equipment frames:
SAt least one BTS starter frame –
–48 V configuration shown in Figure 1-6
+27 V configuration shown in Figure 1-7
SAncillary equipment frame (or wall mounted equipment)
SOne or more Expansion frames (see Figure 1-8 and Figure 1-9).
Expansion frames are essentially the same as starter frames but
incorporate unique components on the I/O (Interconnect) panel.
I/O panel detail is provided for Starter Frame in
Figure 1-12 and Expansion Frame in Figure 1-13
C–CCP cage details are provided in Figure 1-14
NOTE
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 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).
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.

PAs and Carriers
With changes in the network software for R16.4.1, PA allocation to
carriers in the SC4812T–MC changes significantly. The quantity of PAs
required is no longer dependant on the number of carriers equipped in
the frame. Implementation of the change differs between six sector BTSs
and BTSs equipped for omni, two–sector, and three–sector operation.
Additional details for each BTS sector configuration are provided in the
following paragraphs and Figure 1-20, Figure 1-21, and Figure 1-22.
Omni, two–sector, and three–sector multicarrier BTS – Up to four
carriers can be supported on an omni, two–, or three–sector BTS with
one PA set. If additional power output is required, additional PA sets can
be added up to the maximum of four sets. PAs must be added as
complete sets; that is, three PA modules for a 3x3 system and four PA
modules for a 4x4 system. (Refer to Figure 1-20 and Figure 1-21)

BTS Equipment Identification – continued
5/21/04 1X SC4812T–MC BTS Optimization/ATP 1-37
DRAFT
Six–sector BTS – Six–sector operation is only supported in OEM
multicarrier frames. For a six–sector BTS, up to two carriers can be
supported with a minmum of two PA sets: six PA modules for a 3x3
system and eight PA modules for a 4x4 system. If additional power is
required, two additional PA sets can be added for the maximum available
capacity. (Refer to Figure 1-22).
Equipment Configurations
The various components of the PA cages may be configured differently
depending upon customer requirements. Table 1-5 provides BTS
carrier/sector/BBX mapping, TX Filter requirements, and PA quantities
and configurations needed to provide the required BTS output power for
all carriers. Figure 1-16 illustrates which BBXs are used for omni and
two–sector operation. Figure 1-20, Figure 1-21, and Figure 1-22
illustrate the minimum and maximum power PA configurations for
omni, two–, and three–sector OEM and converted multicarrier frames
and for six–sector OEM multicarrier frames, respectively.
