SC 4812ET BTS Optimization/ATP – CDMA LMF
PRELIMINARY 2
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 LMF connection to the
BTS equipment, GPS Verification, Test equipment setup,
downloading all BTS processor boards, RF path verification, BLO
calibration and calibration audit, and Radio Frequency Diagnostic
System (RFDS) calibration.
 Acceptance Test Procedures (ATP) consist of automated ATP tests
executed by the LMF, and used to verify all major transmit (TX) and
receive (RX) performance characteristics on all BTS equipment. Also
generates an ATP report.
 Alarms testing.
 RFDS Optimization.
 Basic troubleshooting
 Preparing to leave the site, presents instructions on how to properly
exit customer site and ensure that all equipment is operating properly
and all work is complete according to Motorola guidelines.
 Appendices that contain pertinent Pseudorandom Noise (PN) Offset,
frequency programming, and output power data tables, along with
additional data sheets that are filled out manually by the CFE at the
site.
