General Safety

Remember! . . . Safety depends on you!!

Ground the instrument

The following general safety precautions must be observed during all phases of operation, service, and repair of the equipment described in this manual. Failure to comply with these precautions or with specific warnings elsewhere in this manual violates safety standards of design, manufacture, and intended use of the equipment. Motorola, Inc. assumes no liability for the customer’s failure to comply with these requirements. The safety precautions listed below represent warnings of certain dangers of which we are aware. You, as the user of this product, should follow these warnings and all other safety precautions necessary for the safe operation of the equipment in your operating environment.

To minimize shock hazard, the equipment chassis and enclosure must be connected to an electrical ground. If the equipment is supplied with a three-conductor ac power cable, the power cable must be either plugged into an approved three-contact electrical outlet or used with a three-contact to two-contact adapter. The three-contact to two-contact adapter must have the grounding wire (green) firmly connected to an electrical ground (safety ground) at the power outlet. The power jack and mating plug of the power cable must meet International Electrotechnical Commission (IEC) safety standards.

Do not operate in an explosive atmosphere

Keep away from live circuits

Do not service or adjust alone

Do not operate the equipment in the presence of flammable gases or fumes. Operation of any electrical equipment in such an environment constitutes a definite safety hazard.

Operating personnel must:

 not remove equipment covers. Only Factory Authorized Service

Personnel or other qualified maintenance personnel may remove equipment covers for internal subassembly, or component replacement, or any internal adjustment.

 not replace components with power cable connected. Under certain

conditions, dangerous voltages may exist even with the power cable removed.

 always disconnect power and discharge circuits before touching them.

Do not attempt internal service or adjustment, unless another person, capable of rendering first aid and resuscitation, is present.

Optimization Manual: Scope and Layout

Scope of This Document

This document provides information pertaining to the optimization and audit tests of Motorola SC 4812T 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 Frame

Installation Manual – 68P09226A18, which covers the physical “bolt

down” of all SC series equipment frames, and the

Installation Manual –68P64113A87 which covers BTS specific cabling

configurations.

In most applications the same test procedure is used for all equipment variations. However, decision break points are provided throughout the procedure when equipment specific tests are required.

IMPORTANT

SC 4812T CDMA BTS

We at Motorola Technical Education & Documentation have strived to incorporate into this document the many suggestions and inputs received from you, the customer, since the inception of the SC product line. At the same time, we have tried to insure that the scope of the document

targets both the novice and expert site technician and engineer with the information required to successfully perform the task at hand. If

in some areas, the manual seems to cover the test in too much detail (or not enough detail) we hope you will keep this in mind.

As the CDMA Local Maintenance Facility (LMF) capability comes on–line, applicable LMF based procedures will be incorporated. Eventually, only the CDMA LMF platform will be supported as the recommended customer method of interfacing with and servicing the SC series BTS equipment.

Purpose of the Optimization

Why Optimize?

What Is Optimization?

Proper optimization and calibration assures:

 Accurate downlink RF power levels are transmitted from the site.  Accurate uplink signal strength determinations are made by the site.

Optimization compensates for the site-specific cabling and normal equipment variations. Cables that interconnect the BTS and Duplexer assemblies (if used), for example, are cut and installed at the time of the BTS frame installation at the site. Site optimization guarantees that the combined losses of the new cables and the gain/loss characteristics and built-in tolerances of each BTS frame do not accumulate, causing improper site operation.

Optimization identifies the accumulated loss (or gain) for all receive and transmit paths at the BTS site, and stores that value in a database.

 The RX path for the starter frame starts at the ancillary equipment

frame RFDS RX directional coupler antenna feedline port, through the ancillary equipment frame RFDS RX directional coupler antenna feedline port, through the RX input port on the top of the frame, through the bandpass filter, Combiner Input/Output (CIO) card, Multicoupler Preselector Card (MPC), and additional splitter circuitry, ending at a Code Division Multiple Access (CDMA) Channel Processor (C–CCP) backplane Broad Band Transceiver (BBX2) slot in the C–CCP shelf.

 The RX path for the expansion frame starts at the ancillary equipment

frame RFDS RX directional coupler antenna feedline port, through the ancillary equipment frame RFDS RX directional coupler antenna feedline port, through the RX input port on the top of the starter frame, through the bandpass filter and CIO card, out the expansion port at the top of the starter frame, through the expansion cable to the expansion port on the expansion frame, through the Expansion Multicoupler Preselector Card (EMPC) and CIO, ending at a Broad Band Transceiver (BBX2) slot in the C–CCP shelf.

 The TX path starts at the BBX2, through the C–CCP backplane slot,

travels through the LPA/Combiner TX Filter and ends at the top of the RFDS TX directional coupler antenna feedline port (CDMA), installed on the ancillary equipment frame. If the RFDS option is added, then the TX path continues and ends at the top of the RFDS TX directional coupler antenna feedline port installed in the ancillary equipment frame. The TX paths are identical for the starter and expansion frames.

Purpose of the Optimization – continued

These values are factored in by the BTS equipment internally, leaving only site specific antenna feed line loss and antenna gain characteristics to be factored in by the CFE when determining site Effective Radiated Power (ERP) output power requirements.

Each C–CCP shelf BBX2 board is optimized to a specific RX and TX antenna port. (One BBX2 board acts in a redundant capacity for BBX2’s 1–12, and is optimized to all antenna ports.) A single value is generated for each path, thereby eliminating the accumulation of error that would occur from individually measuring and summing the gain and loss of each element in the path.

When to Optimize

New Installations

After the initial site installation, it must be prepared for operation. This preparation includes verifying hardware installation, initial power–up, download of operating code, and Clock Synchronization Module (CSM) verification.

Next, the optimization is performed. Optimization includes performance verification and calibration of all transmit and receive RF paths, and download of accumulated calibration data.

After optimization, a series of manual pre–ATP verification tests are covered that address alarm/redundancy tests.

After manual pre–Acceptance Test Procedure (pre–ATP) verification tests, a series of manual ATP CDMA verification tests are covered using the actual equipment set up. An ATP is also required before the site can be placed in service.

Site Expansion

Optimization is also required after expansion of a site.

Periodic Optimization

Periodic optimization of a site may also be required, depending on the requirements of the overall system.

Repaired Sites

Required Test Equipment

Policy

The LMF is used in conjunction with Motorola recommended test equipment and is part of a “calibrated test set”. To ensure consistent, reliable, and repeatable optimization test results, only recommended test equipment supported by the LMF must be used to optimize the BTS equipment.

NOTE

During manual testing, you can, of course, substitute test equipment with other test equipment models not supported by the LMF, but those models must meet the same technical specifications.

The customer has the responsibility of accounting for any measurement variances and/or additional losses/inaccuracies that can be introduced as a result of test equipment substitutions. Before beginning

optimization or troubleshooting, make sure that the test equipment needed is on hand and operating properly.

Test Equipment Calibration

Test Cable Calibration

Equipment Warm–up

Optimum system performance and capacity depend on regular equipment service, calibration, and characterization prior to BTS optimization. Follow the original equipment manufacturer (OEM) recommended maintenance and calibration schedules closely.

Equipment test cables are very important in optimization. Motorola recommends that the cable calibration be run at every BTS with the test cables attached. This method compensates for test cable insertion loss within the test equipment itself. No other allowance for test cable insertion loss needs to be made during the performance of tests.

Another method is to account for the loss by entering it into the LMF during the optimization procedure. This method requires accurate test cable characterization in a shop. The cable should be tagged with the characterization information prior to field optimization.

After arriving at the a site, the test equipment should be plugged in and turned on to allow warm up and stabilization to occur for as long as possible. The following pieces of test equipment must be warmed–up for a minimum of 60 minutes prior to using for BTS optimization or Radio Frequency Diagnostic Subsystem (RFDS) calibration procedures.
