Optimization Manual Scope and Layout
FEB 2005 1X SC 4812T Lite BTS Optimization/ATP 1-1
PRELIMINARY
Manual Scope and Layout
This document provides information pertaining to the Optimization and
Audit Tests of the Motorola 1X SCt4812T–Lite BTS frame. The
following subjects are addressed: preliminary background information,
Optimization and Alarm/Redundancy Tests, Acceptance Test Procedures
(ATP) to verify Site Operation, Regulation Compliance, Site Turnover;
and Troubleshooting.
This Optimization Procedure consists of a group of task-oriented tests.
Each major test category (Audit, Initial Power–up, Calibration, etc.) is
described in chapters that are broken down into multi-Page “Information
Maps”.
Each “Map” contains the information necessary to perform the test or
operation. Included are all required Input Levels, Output Levels, Local
Maintenance Facility (LMF) Application Software Commands, and Test
Point Identification. Also described are important Test Process Concepts
and Equipment Operation that should be understood by the operator.
Whenever possible, graphics, flowcharts, or written examples
complement the information or procedural Steps.
Assumptions and Prerequisites
This document assumes that the BTS Frames and cabling have been
installed per the 1X SC 4812T–Lite BTS Hardware Installation ,
68P09262A57 that covers both the physical “bolt down” of the
SC 4812T Lite BTS Frame and the specific Cabling Configurations.
Document Composition
This document covers the following major areas:
S Introduction: consists of preliminary background information (such
as component and Sub–assembly locations and frame layouts) to be
considered by the Cellular Field Engineer (CFE) before performing
Optimization or ATP.
S Preliminary Operations: consists of Jumper Configuration of BTS
Sub–assemblies, Pre–Power–up Tests, Initial Application of Electric
Power to the BTS Equipment Frames, and Initial Power–up Tests.
S Optimization/Calibration: consists of procedures for downloading
all BTS Processor Cards, Test Equipment Set–up, RF Path
Verification, BLO Calibration and Calibration Audit, and Radio
Frequency Diagnostic System (RFDS) Calibration.
S Acceptance Test Procedures (ATP): consists 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. This chapter also covers generating an ATP Report.
S Prepare to Leave the Site: discusses site turnover after the ATP is
completed.
