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 Cellular Field Engineer (CFE) before optimization

or tests are performed.

 Preliminary Operations, consisting of pre–power up tests, jumper

configuration of BTS sub–assemblies, and initial application of power

to the BTS equipment frames. Download of all BTS processor boards,

and LPAs.

 Optimization/Calibration, consisting of downloading all BTS

processor boards, LPA verification, radio frequency (RF) path

verification, Bay Level Offset (BLO) calibration, and Radio

Frequency Diagnostic System (RFDS) functions and calibration

 Acceptance Test Procedures (ATP), consisting of automated ATP

scripts 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.

 Optional manual performance tests used to verify specific areas of site

operation or to verify regulation compliance. These tests are typically

used to isolate faults down to the module level and information

necessary to better understand equipment operation.

 Site turnover after ATP is completed.

 Appendices that contain pertinent data sheets that are filled out

manually by the CFE at the site, Pseudorandom Noise (PN) Offset

information, an optimization/ATP matrix , output power data tables,

CDMA operating frequency programming information, manual test

setup information, procedures for verifying that the Voltage Standing

Wave Ratio (VSWR) of all antennas and associated feed lines fall

within acceptable limits, procedures for downloading ROM and RAM

code, and procedures for performing in–service ATP.
