User Manual
1X UBS Macro B T S Optimization/A TP Scope and La y out
Intended Reader Prole
The information in this manual set is intended for use by cellular communications personnel in
the initial installation and configuration, as well as the day -to -day operation and maintenance
of a UBS .
The user of this information must have a general understanding of telephony , as used in the
operation of the Public Switched T elephone Network (PSTN), and must be familiar with these
concepts as they are applied in the cellular and mobile/portable radio telephone maintenance
environment.
The user also must have a working knowledge of W indows 2000 or W indows XP™.
Publication Composition
This publication covers the following areas.
• Introduction: preliminary background information (such as component and subassembly
locations and UBS layouts) to be considered by the Cellular Field Engineer (CFE) before
optimization or tests are performed.
• Preliminary Operations: UBS subassemblies, pre–power up tests, initial power application,
and power–up tests for the UBS after installation.
• Optimization: code syncing all UBS processor boards, test equipment setup and calibration,
UBS verification, radio frequency (RF) path verification, and RF calibration as necessary .
• Field V erification: A t the site the UBS is assembled per the installation manual and tested
using TX Audit and RS SI procedures.
• Acceptance T est Procedures (A TP): automated A TP scripts executed by the LMF and used
to verify all major transmit (TX) and receive (RX) performance characteristics on all UBS
equipment. Includes generating an A TP report. Using the full A TP is optional.
• Prepare to Leave the Site: site turnover process after A TP is completed.
• Basic Troubleshooting: procedures to perform when an A TP fails, as well as when incorrect
results are obtained during logon, test equipment operation, audit, and Global P ositioning
System (GPS) operation. These tests are typically used to isolate faults down to the module
level. Also provided is additional information necessary to better understand equipment
operation.
• Appendices containing data sheets to be filled out manually by the CFE at the site,
optimization/A TP matrix, output power data tables, CDMA operating frequency
programming information, and manual test setup information. .
