Automated Acceptance Test Procedure
Introduction
The Acceptance Test Procedures (ATP) allow Cellular Field Engineers (CFEs) to run automated Acceptance Tests on all BTS Subsystem Devices equipped in the CDF using the LMF and the Test Equipment it supports.
The CFE can choose to save the results of ATP Tests to a report file from which ATP Reports are generated for later printing. See the Generating an ATP Report section in this chapter.
Because Test Equipment Functions during Acceptance Testing are controlled by the LMF through the GPIB, only the Test Equipment Models supported by the LMF can be used.
NOTE
– Before using the LMF, read the Release Notes
“Caveats” section in the WinLMF On-Line Help SR2.16.x for any applicable information.
– The ATP Test is to be performed on out-of-service
sectors only.
– DO NOT substitute Test Equipment with other
models not supported by the LMF.
4
Reduced A TP
Refer to Chapter 3 for detailed interconnection information needed for calibrating equipment, cables, and other Test Equipment Set components.
NOTE
Equipment has been factory–tested for FCC Compliance. If license–governing bodies require documentation
supporting BTS Site Compliance with regulations, a full ATP may be necessary.
Perform the Reduced ATP only if reports for the specific BTS Site are NOT required.
After downloading the proper operational software to the BTS, the CFE must perform these procedures (minimum recommendation):
1. Verify that the TX/RX Paths by performing TX Calibration, TX Audit, and FER Tests.
2. Retrieve Calibration Data required for normal site operation.
Should failures occur while performing the specified tests, refer to the Basic Troubleshooting section of this manual for help in determining the failure point. Once the point of failure has been identified and corrected, refer to the BTS Optimization and ATP Test Matrix (Table C-1) to determine the applicable test that must be performed.

PRELIMINARY
Automated Acceptance Test Procedure – continued
In the unlikely event that the BTS passes these tests but has a Forward Link problem during normal operation, the CFE should then perform the additional TX Tests for troubleshooting: TX Spectral Mask, TX Rho, and TX Code Domain.
ATP Test Options
ATP Tests can be run individually or as one of the following groups:
S All TX: TX Tests verify that the performance of the BTS Transmit
Elements. These include the GLI, MCC, BBX, Trunking Modules, the LPA Modules, and passive components including Splitters, Combiners, Bandpass Filter(s), and RF Cables.
S All RX: The RX Test verifies the performance of the BTS Receive
4
Elements. These include the MPC, EMPC (for Companion Frames), BBX, MCC, GLI Cards, and the passive components including RX Filters and RF Cables.
S All TX/RX: Executes all TX and RX Tests.
ATP Prerequisites
S Full Optimization: Executes the TX Calibration, downloads BLO,
and executes the TX Audit before running all TX and RX Tests.
Before attempting to run any ATP Tests, ensure that the following have been completed:
S BTS has been optimized (BBX Cards calibrated and BLOs
downloaded) (Chapter 3)
S The carrier(s) and/or sector(s) to be tested have been taken out of
service at the CBSC.
S LMF is logged into the BTS. S CSM Cards, GLI Cards, BBX Cards, MCC Cards and TSU (if the
RFDS is installed) have correct code and Data Loads.
S Primary CSM and GLI are INS_ACTIVE (bright green). S MCC Cards are INS_ACTIVE (bright green). S No BBX Cards are keyed (transmitting). S BBX Cards are OOS_RAM (yellow). S Test Cables are calibrated. S Test Equipment has been selected, warmed–up 60 minutes, and
calibrated.
S GPIB is on. S BTS Transmit Connectors are properly terminated for the test(s) to be
performed.

n Step Action
1 If it has not already been done, interface the LMF Computer to the BTS.
– Refer to Table 3-6 and Figure 3-3.
2 If it has not already been done, start a GUI LMF Session and log into the BTS.
– Refer to Table 3-10.
3 If it has not already been done, connect Test Equipment for Acceptance Testing.
– Refer to Figure 3-20, Figure 3-21, Figure 3-22, Figure 3-23, Figure 3-24, or Figure 3-25, as
applicable, for the Test Equipment and Antenna Duplexing being used.
* IMPORTANT
LMF–based Measurements factor into TX Test Test Cable Insertion Loss between the RF Modem Frame and Test Equipment.
If additional attenuation, such as external TX Combiners, is inserted in the path, it must be identified to the LMF by including it in the TX Test Cable Calibration.
– If this is not possible, include the attenuation in the TX Path by editing Test Cable Insertion
Loss Values (refer to Table 3-35).
– Failure to do this will result in test inaccuracies and potential for erroneous ATP failures
because the additional losses would not be compensated for in the test measurements.

Abbreviated (All–inclusive) Acceptance Tests
All–inclusive Tests
General
The all–inclusive Acceptance Tests are performed from the LMF GUI Environment. These all–inclusive tests are called abbreviated ATPs because they execute various combinations of individual Acceptance Tests with a single command. This allows verification of multiple aspects of BTS performance while minimizing time needed for individual Test Set–up and initiation.
Abbreviated ATP Options
There are three abbreviated Acceptance Tests that evaluate different performance aspects of the BTS. This allows the CFE to select testing to
4
meet the specific requirements for individual Maintenance and Performance Verification situations. The following items summarize the coverage of each Abbreviated Test.:
S All TX/RX: Performs all transmit and receive ATPs on the selected
MCC Cards and BBX Cards.
S All TX: Performs complete set of transmit ATPs on the selected MCC
Cards and BBX Cards. Testing is the equivalent of performing all of the following individual tests:
– TX Mask Test – Rho Test – Pilot Time Offset Test – Code Domain Power Test
S All RX: Performs complete Receive ATP on the selected MCC Cards
and BBX Cards. Testing is the equivalent of performing the FER Test.
Abbreviated Acceptance Test Procedures
Procedures to accomplish each type of Abbreviated ATP are included in the following subsections..
All TX/RX A TP Test
Perform the procedure in Table 4-2 to perform the Abbreviated, All–inclusive Transmit And Receive Test.

Individual Acceptance Tests
RX and TX Testing
The following individual ATP Tests can be used to evaluate specific aspects of BTS Operation against individual performance requirements. All testing is performed using the LMF GUI Environment.
TX Testing
TX Tests verify any given Transmit Antenna Path and Output Power Control. All tests are performed using the external, calibrated Test Equipment. All measurements are made at the appropriate BTS TX OUT Connector(s).
TX Tests verify TX Operation of the entire CDMA Forward Link using selected BBX Cards assigned to respective Sector Antennas. Each BBX is keyed–up to generate a CDMA Carrier (using both bbxlevel and BLO) at the CDF File–specified Carrier Output Power Level.
RX Testing
RX Testing verifies Receive Antenna Paths for BBX Cards selected for the test. All tests are performed using the external, calibrated Test Equipment to inject a CDMA RF Carrier with all zero Longcode at the specified RX Frequency at the appropriate BTS RX IN Connector(s).
RX Tests verify RX Operation of the entire CDMA Reverse Link using all equipped MCC Cards assigned to all respective sector/antennas.
4
Individual Tests
Spectral Purity TX Mask
This test verifies that the transmitted CDMA Carrier Waveform generated on each sector meets the transmit Spectral Mask Specification (as defined in IS–97) with respect to the assigned CDF File Values.
Waveform Quality (Rho)
This test verifies that the transmitted Pilot Channel Element Digital Waveform Quality (Rho) exceeds the minimum specified value in IS–97. Rho represents the correlation between the actual and perfect CDMA Modulation Spectrums. 1.0000 represents 100% (or perfect correlation).
Pilot Time Offset
The Pilot Time Offset is the difference between the Communications System Test Set Measurement Interval (based on the BTS System Time Reference) and the incoming block of transmitted data from the BTS (Pilot only, Walsh Code 0).
Code Domain Power/Noise Floor
This test verifies the Code Domain Power Levels, that have been set for all ODD numbered Walsh Channels, using the OCNS Command. This is done by verifying that the ratio of PILOT divided by OCNS is equal to
2 dB, and, that the Noise Floor of all EVEN–numbered “OFF”
10.2 +
Walsh Channels measures < –27 dB for IS–95A/B and CDMA2000 1X with respect to total CDMA Channel Power.

TX Spectral Purity Transmit Mask Acceptance Test
Background
Overview
This test verifies the Spectral Purity of each operator–selected BBX Carrier keyed–up at a specific frequency specified in the current CDF. All tests are performed using the external, calibrated Test Equipment controlled by the same command. All measurements are made at the appropriate BTS TX Antenna Connector..
Test Patterns
There are four operator–selectable Test Patterns with which this Acceptance Test can be performed. The patterns, along with the channels tested and Gain Setting for each, are listed in Table 3-40. Refer to “TX Calibration and the LMF” in the Bay Level Offset Calibration section of Chapter 3 for more information on the Test Patterns..
Equipment Operation During Testing
At least one MCC must be selected to perform the Standard, CDF Pilot, and CDF Test Patterns. For these Test Patterns, Forward Links are enabled for Synch Channel (SCH), Paging Channel (PCH), and Traffic Channel (TCH) Elements from the selected MCC(s), as shown in Table 3-40.
Gain is set for the applicable channels on each antenna as shown in the table. The operator–selected BBX Cards will be keyed using a BLO–corrected bbxlvl Value to generate a CDMA Carrier. RF Output Power, as measured at the appropriate Frame TX Antenna Connector, will be set to one of the following depending on the Operating Frequency Spectrum.:
S 800 MHz: 33.5 dBm S 1.9 GHz: 31.0 dBm
4
Test Measurements
The Test Equipment will measure and return the attenuation level in dB of all spurious and IM products with respect to the Mean Power of the CDMA Channel measured in a 1.23 MHz bandwidth, verifying that results meet system tolerances at the following test points. Refer to also Figure 4-2):
S For 800 MHz:
– At least –45 dB @ + 750 kHz from Center Frequency – At least –45 dB @ – 750 kHz from Center Frequency – At least –60 dB @ – 1980 kHz from Center Frequency – At least –60 dB @ + 1980 kHz from Center Frequency
S For 1.9 GHz:
– At least –45 dB @ + 885 kHz from Center Frequency – At least –45 dB @ – 885 kHz from Center Frequency – At least –55 dB @ – 1980 kHz from Center Frequency – At least –55 dB @ + 1980 kHz from Center Frequency

Basic Troubleshooting: RF Path Fault Isolation
Overview
The Optimization (RF Path Characterization or Calibration) and Post-Calibration (Audit) Procedures measure and limit-check the BTS reported Transmit and Receive Levels of the path from each BBX to the back of the frame. When a fault is detected, it is specific to a Receive or Transmit Path. The Troubleshooting Process in this section determines the most probable cause of the fault.
As the Calibration and Audit Tests are performed, results are displayed in the LMF Test Status Report Window. When faults are encountered, the Test Procedure in progress continues running and displaying any further faults. If it appears that there are major faults, the test can be aborted.
The test results can be saved to a directory \cdma\bts–# Folder. To do this, close the Test Status Report Window using the Save Results Button.
NOTE
Closing the Test Status Report Window with the Dismiss Button will delete the test results without saving them.
If a test is re–run or a new calibration, audit, or test is run and the results are saved, the previous test results in the bts–#.rpt File are overwritten. To prevent losing previous test results in the bts–#.rpt

If Every Test Fails
File, refer to the procedure in Table 4-10 before performing further testing with the LMF.
If there are major faults, recheck the Test Equipment Attachments for errors. If none are found, close the Test Status Report Window using the Save Results Button, and save the contents of the resulting bts–#.rpt file as described in Table 4-10. Also, note other specifics about the failure, and proceed with the Fault Isolation Procedure.
If all tests fail, perform the procedure in Table 6-14.

Verify BLO Check Box
When performing a Calibration with the TX Calibration... or All Cal/Audit... Functions, the Verify BLO Check Box should normally be
checked. When a Calibration fails, determine if any items such as Directional Couplers or Combiners have been added to the TX Path.
If additional items have been installed in the path, try re–running the Calibration with Verify BLO unchecked. If Calibration still does not pass, refer to the following paragraphs and use the TX Output Fault Isolation Flowchart to identify the most probable cause of the failure.
Single–Sided BLO Check Box
When performing a Calibration with the TX Calibration... or All Cal/Audit... Functions, the Single–Sided BLO Check Box should not
be checked when the Redundant BBX is being calibrated. When a Calibration fails with the Redundant BBX selected, try re–running the Calibration with the Single–Sided BLO Check Box unchecked.
– If the Calibration still fails, refer to the following paragraphs and
use the TX Output Fault Isolation Flowchart to identify the most probable cause of the failure.
If Faults Are Isolated
Fault Isolation Flowchart
If the Fault Reports are isolated between successful Path Checks, the root cause of the faults most likely lies with one or more of the Field Replaceable Unit (FRU) cards/modules.
– If more than one failure was reported, look for a common
denominator in the data. For example, if any TX Test fails on one sector only, the BBX assigned to that sector (Table 1-5) is a likely cause. Also, look at the Severity of the failure.
– If the Path Loss is just marginally out of the relaxed specification
limit during the Post-Calibration TX Audit, suspect excessive Test Cable Insertion Loss.
– If limits are missed by a wide margin, suspect incorrectly wired
cables or total device failure.
Use the TX Output Fault Isolation Flowchart in Figure 6-1 to identify the strongest possible cause for a failed TX Test.
The flowchart covers the Transmit Path.
– Transmit Paths usually fail the lower Test Limit, indicating
excessive Loss in some component in the BTS Site or incorrect wiring.
– A failure of an upper Test Limit usually indicates a problem with
the Test Set–up or external equipment.
Before replacing a suspected FRU, always repeat and verify that the test results to rule out a transient condition. If a BBX fails an Upper Limit in the Post–Calibration Audit Procedure, re–calibrate and verify that the out–of–tolerance condition for that BBX and/or sector before replacement.

Troubleshooting: SCCP Backplane
Introduction
The SCCP Backplane is a multi–layer printed circuit board that interconnects all of the SCCP Cards and Modules. The complexity of this board lends itself to possible improper diagnoses when problems occur.
Connector Functionality
The following Connector Overview describes the major types of Backplane Connectors along with the functionality of each. This will assist the CFE to:
S Determine which connector(s) is associated with a specific problem
type.
S Isolate problems to a specific cable or connector.
Span Line Connector
The 50–pin Span Line Connector provides a primary and secondary (if used) Span Line Interface to each GLI in the SCCP Cage. The Span Line is used for MM/EMX Switch Control of the Master GLI and also all of the BBX Traffic.
Power Input (Return A and B Connectors)
Provides 27 Volt Input for use by the Power Supply Modules.
Power Supply Module Interface
Each Power Supply Module has a series of three different connectors to provide the needed inputs/outputs to the SCCP Backplane. These are:
– VCC/Ground Input Connector – Harting–style Multiple Pin Interface – +15V Analog Ground Output Connector
The Transceiver Power Module converts 27 Volts to a regulated +15, +6.5, +5.0 Volts to be used by the SCCP Cage Cards.
GLI Connector
This connector consists of a Harting 4SU Digital Connector and a 6–conductor COAXial Connector for RDM Distribution. The connectors provide inputs/outputs for the GLI Cards in the SCCP Backplane.
GLI Ethernet “A” and “B” Connections
These SMB Connectors are located on the SCCP Backplane and connect to the GLI Card. This interface provides all the Control and Data Communications over the Ethernet LAN between the Master GLI, the Redundant GLI, and the LMF.
6
BBX Connector
Each BBX Connector consists of a Harting 2SU/1SU Digital Connector and two 6–conductor COAXial Connectors. These connectors provide DC, Digital, and RF Inputs/Outputs for the BBX Cards in the SCCP Backplane.
FEB 2005 1X SC 4812T Lite BTS Optimization/ATP 6-23
PRELIMINARY
Troubleshooting: SCCP Backplane – continued
CIO Connectors
S RF RX Antenna Path Signal Inputs are routed through RX Paths of
the DRDCs or TRDCs at the RF Interface Panel (rear of the frame), and through COAXial Cables to the two MPC Cards.
The three “A” (Main) Signals go to one MPC; the three “B” (Diversity) Signals to the other. The MPC outputs the low–noise–amplified signals through the SCCP Backplane to the CIO where the signals are split and sent to the appropriate BBX.
S A Digital Bus then routes the Baseband Signal through the BBX, to
the SCCP Backplane, and then on to the MCC Slots.
S Digital TX Antenna Path Signals originate at the MCC Cards. Each
output is routed from the MCC Slot through the SCCP Backplane to the appropriate BBX.
S TX RF Path Signal originates from the BBX, travels through the
SCCP Backplane to the CIO, through the CIO, and then through multi-conductor COAXial Cabling to the Trunking Module and LPA Modules in the LPA Shelf.
SCCP Backplane Troubleshooting Procedure
The following tables provide standard procedures for troubleshooting problems that appear to be related to a defective SCCP Backplane. The tables are broken down into possible problems and steps that should be taken in an attempt to find the root cause.
