Introduction
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.
Also covered is software release 2.16.1.X and can support the following
versions of SC 4812ET BTS sites:
- 1X Packet Backhaul BTS
- 1X Circuit BTS
- 1X Packet backhaul BTS
The 1X packet BTS has a packet backhaul network interface which
provided via a pair of external routers together with a GLI upgrade
(GLI3) that can handle voice (IS-95A/B, 1X) and data (IS-95B, 1X).
This BTS equipment is configured with all 1X cards (BBX-1X
andMCC1X) or a mix of 1X cards and non-1X cards (BBX2 and
MCC8E/24E). This configuration is compliant with all applicable
cdma2000 1X specifications. It provides the forward link and reverse
link RF functions to support 2G features and 3G-1X features (i.e., high
capacity voice & high bit rate data).
The 1X circuit BTS has a split backhaul (circuit/packet pipe) network
interface that can handle circuit based voice (IS-95A/B, 1X) and data
(IS-95B) as well as packet based data (1X).
This document assumes the following prerequisites: The BTS frames
and cabling have been installed per the BTS Hardware Installation
Manual 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 Local Maintenance
Facility (LMF) connection to the BTS equipment, Global Positioning
System (GPS) Verification, test equipment setup, downloading all
BTS processor boards, RF path verification, Bay Level Offset (BLO)
calibration and calibration audit, and Radio Frequency Diagnostic
System (RFDS) calibration.
Acceptance Test Procedures (ATPs), consisting of ATP tests executed
by the LMF and used to verify all major transmit (TX) and
receive (RX) performance characteristics on all BTS equipment.
Preparing to leave the site, presents instructions on how to properly
exit customer site, ensure that all equipment is operating properly, and
all work is complete according to Motorola guidelines.
