Optimization Manual Scope and Layout

Manual Scope and Layout

This document provides information pertaining to the optimization and audit tests of the Motorola SC4812ET Lite RF Base Transceiver Station (BTS) equipment frame and its associated internal and external interfaces. The following subjects are addressed: preliminary background information; optimization, and alarm/redundancy tests; Acceptance Test Procedures (ATP) to verify site operation and regulation compliance; site turnover; troubleshooting.

Most applications use the same test procedure for all equipment variations. However, decision break points are provided throughout the procedure when equipment–specific tests are required. For example, when tests using external test equipment are performed instead of those using the RFDS, additional test procedures and illustrations are provided to cover both applications.

This optimization procedure consists of a group of task-oriented tests. Each major test category (Audit, Initial power–up, Calibration tests, etc.) is described in chapters which are broken down into multi-page “maps.”

Assumptions and Prerequisites

Each “map” typically consists of pages containing all the information necessary to perform the test (including all required input levels, output levels, CDMA Local Maintenance Facility (CDMA LMF) commands, and test points required). Also described are some of the main concepts you must understand in the test process. Whenever possible, graphics, flowcharts, or other examples complement the information/steps.

This document assumes that the BTS frames and cabling have been installed per the Frame Mounting Guide Analog/CDMA/TDMA; 68P09226A18, which covers the physical “bolt down” of all SC series equipment frames, and the SC4812ET Lite Installation; 68P09253A36, which covers BTS–specific cabling configurations.

Document Composition

This document covers the following major areas:

S 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 performing optimization or tests.

S Preliminary Operations, consisting of jumper configuration of BTS

sub–assemblies, pre–power–up tests, initial application of power to the BTS equipment frames, and initial power–up tests.

S Optimization/Calibration, consisting of procedures for downloading

all BTS processor boards, test equipment set–up, RF path verification, BLO calibration and calibration audit, and Radio Frequency Diagnostic System (RFDS) calibration.

S Acceptance Test Procedures (ATP), consisting of automated ATP tests,

executed by the CDMA LMF, and used to verify all major TX and RX performance characteristics on all BTS equipment. This chapter also covers generating an ATP report.

S Prepare to Leave the Site, discussing site turnover after ATP is

completed.

S Basic Troubleshooting, consisting of procedures to perform when an

ATP fails, as well as when incorrect results are obtained during logon, test equipment operation, calibration, and GPS operation.

S Appendices that contain pertinent 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.

Purpose of the Optimization

Why Optimize?

What Is Optimization?

What Happens During Optimization

Proper optimization and calibration ensures that:

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

Optimization compensates for the site-specific cabling and normal equipment variations. 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 and cause improper site operation.

Optimization identifies the accumulated loss (or gain) for each receive and transmit path at the BTS site, and stores these values in a database.

S A receive path (RX) starts at the Duplexer Directional Coupler

(DRDC) or Transmit & Receive Dual Directional Coupler (TRDC) antenna feedline port and travels through the DRDC/TRDC, the Multi–coupler Preselector Card (MPC) and additional splitter circuitry, ending at a Broad Band Transceiver (BBX) backplane slot in the Small CDMA Channel Processor (SCCP) shelf.

S A transmit path (TX) starts at the SCCP shelf BBX backplane slot, is

routed to the Linear Power Amplifier (LPA) Trunking Module, through the LPAs, back through the LPA Trunking Module, through the bandpass filter or 2–cavity combiner, and ends at the DRDC/TRDC antenna feedline port.

Six of the seven BBX2 boards in each SCCP shelf are optimized to specific RX and TX antenna ports. The seventh BBX2 board acts in a redundant capacity for BBX2 boards 1 through 6, and is optimized to all antenna ports. A single value is generated for each complete 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.

BTS equipment factors in these values 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.

When to Optimize

New Installations

After the initial site installation, the BTS must be prepared for operation. This preparation includes verifying hardware installation, initial power–up, downloading of operating code, verifying GPS operation and verifying transmit and receive paths.

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

A calibration audit of all RF transmit paths may be performed any time after optimization to verify BTS calibration.

After optimization, a series of manual pre–Acceptance Test Procedure (ATP) verification tests are performed to verify alarm/redundancy performance.

After manual pre–ATP verification tests, a series of ATPs are performed to verify BTS performance. An ATP is also required before the site can be placed in service.

Site Expansion

Periodic Optimization

Repaired Sites

Optimization is also required after expansion of a site with additional, interconnected BTS frames.

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

IMPORTANT

Refer to Appendix B for a detailed FRU Optimization/ATP Test Matrix outlining the minimum tests that must be performed any time a BTS subassembly or RF cable associated with it is replaced.

Required Test Equipment and Software

Policy

To ensure consistent, reliable, and repeatable optimization test results, test equipment and software meeting the following technical criteria should be used to optimize the BTS equipment. Test equipment can, of course, be substituted with other test equipment models if the equipment

meets the same technical specifications. It is the responsibility of the customer to account for any measurement

variances and/or additional losses/inaccuracies that can be introduced as a result of these substitutions. Before beginning optimization or

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

Test Equipment Calibration

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

Test Cable Calibration

Equipment Warm–up

Equipment test cables are very important in optimization. It is recommended 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 CDMA 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 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 RFDS calibration procedures:

S Communications test set. S Rubidium time base. S Power meter.

BTS Equipment Identification

Equipment Overview

The SC4812ET Lite BTS frame consists of a single, outdoor, weatherized cabinet containing RF and power components. The BTS is functionally similar to the two–cabinet SC4812ET, but provides more flexibility in site selection because of its smaller footprint and lighter weight. The BTS is powered by 240 Vac, rectified internally to +27 Vdc, and can support up to two carriers in a 3–sector configuration. An SC4812ET Lite starter frame with the maximum of one SC4812ET Lite expansion frame can support a maximum of four carriers in a 3–sector configuration. Six–sector operation is not supported with any SC4812ET Lite configuration.

The BTS frame houses the fan modules, RF compartment heat exchanger, Small CDMA Channel Processor shelf (SCCP), RF Linear Power Amplifier (LPA) modules, LPA trunking modules, bandpass filters or 2:1 combiners, and Duplexer Directional Couplers (DRDC) or Triplexer Directional Couplers (TRDC). Power components include an AC Load Center (ACLC), rectifiers, a +27 Vdc Power Distribution Assembly (PDA), backup batteries, battery heaters, and one duplex GFCI 115 Vac utility outlet.

Logical BTS Numbering

An SC4812ET Lite logical BTS can consist of up to two SC4812ET Lite frames. In a logical BTS, all frames located at a site are identified as parts of a single, numbered BTS (for example, BTS–812). Each frame is assigned a unique frame number. The first, or starter, frame of a logical BTS has a –1 suffix (for example, BTS–812–1) and the second, or expansion, frame of the logical BTS is numbered with the suffix, –101 (e. g. BTS–812–101).

Figure 1-1 shows the frame configuration for a logical BTS consisting of two SC4812ET Lite frames. The figure also shows the BTS–to–CBSC Transcoder and inter–frame span configurations which can be employed with an SC4812ET Lite logical BTS.

Internal Assembly Location and Identification – continued

AC Load Center (ACLC)

The ACLC is the frame entry point for AC power. It incorporates AC power control, distribution, and surge protection (Figure 1-3).

Back–up Batteries

The batteries (Figure 1-3) provide +24 Vdc back–up for the frame should AC power be interrupted. The frame can accommodate a total of 12 12V batteries grouped in six strings. Each string consists of two batteries connected in series for 24 Vdc output. The six strings are connected in parallel to meet the current–draw requirements of the frame. The maximum time duration of the back–up capability depends on system configuration.

Battery Heaters

The battery heater pads warm the batteries to provide improved cold–weather performance. A separate heater pad is required for each battery string and is located between each battery string and its respective support shelf.

Channel Service Units (CSU) (Optional)

The SC4812ET Lite can be equipped with up to two M–PATH 537 CSU or two M–PATH 437 CSU modules which install in the CSU shelf (Figure 1-3). These modules allow monitoring of span performance and provide capability for remote network management.

CSU Shelf

The CSU shelf is an ADC Kentrox 2–slot Universal Shelf which can accommodate two M–PATH 537 or two M–PATH 437 CSU modules. When the optional CSU modules are not installed, cover plates are installed over the CSU card slots (Figure 1-3).

DC Power Distribution Assembly (PDA)

Both rectifier output voltage and back–up battery voltage are routed to the PDA (Figure 1-3) where they are combined into system DC bus voltage. The PDA provides distribution of DC power and system DC bus protection from the loads with MAIN BREAKER and the smaller post–distribution circuit breakers. MAIN BREAKER permits removal of all frame loading from the bus. The 13 post–distribution circuit breakers permit removal of individual loads.

Duplexer, Receive filter, Dual Directional Coupler (DRDC)

DRDCs permit duplexing of sector transmit and receive signals on a single antenna. The DRDCs also incorporate a receive bandpass filter and dual directional couplers which permit signal monitoring by the RF Diagnostic Subsystem.

08/01/2001

ET Interface Board (ETIB) and LPA Control (LPAC) Board

The ETIB is an interconnect module with status LEDs, MMI recepticles, and secondary surge protection for the LPA modules. The LPAC board provides the interface for the LPA connections (Figure 1-3).

Filter/Combiner Shelf (Bandpass Filters or 2:1 Combiners)

The filter/combiner shelf (Figure 1-3) holds the transmit bandpass filters or 2:1 combiners, depending on system configuration.

Heat Exchanger

The heat exchanger provides cooling to the frame RF compartment. The fan speed of the heat exchanger adjusts automatically with temperature. The heat exchanger is located in the frame main door (Figure 1-2).

Punchblock

The punchblock (Figure 1-4) is the interface between the frame and the T1/E1 span lines. It is located on the right–hand side of the power entry compartment at the rear of the frame. The punchblock provides the initial interconnection between the spans and the Customer–defined I/O, alarms, multi–frame timing source (RGPS and RHSO), and pilot beacon control (optional).

Rectifiers

The rectifiers (Figure 1-3) convert AC power supplied to the frame to +27.4 Vdc which powers the frame and maintains the charge of the back–up batteries. Rectifier positions are numbered 1 through 4 from left to right when facing the frame. Single–carrier frames are equipped with three rectifiers installed in positions 1, 2, and 3. Two–carrier frames are equipped with four rectifiers. The number of rectifiers supplied with each configuration provides N+1 redundancy.

RF Diagnostic Subsystem (RFDS)

The RFDS (Figure 1-5) provides the capability for remotely monitoring the status of the SC4812ET Lite transmit and receive paths. For IS–95A/B operation, the RFDS is a COBRA model. To support 1X operation, the RFDS must the 1X–capable COBRA–II.

SCCP Cage Configuration and the 1X Devices

SC4812ET Lite frames have one SCCP cage which will support up to 4 MCC cards and 6 BBX cards.

MCC Cards

A BTS may be configured with a mix of MCC–8E, MCC–24, and MCC–1X cards. Any MCC card slot will support any of the three MCC types. For 1X capability under R16.0, at least one MCC card must be an MCC–1X which can be installed in any MCC card slot.

BBX Cards

Up to 6 BBX cards of mixed BBX2s and BBX–1Xs can also be supported. BBX card slots 1 through 6 are carrier– and sector–dependent. As a result, the BBX slots dedicated to the sectors for one carrier should be populated with the same type of cards. Refer to Table 1-5 for BBX card slot carrier and sector correlations.

The BBX–R1 card slot is dedicated to the redundant BBX. This slot will support either a BBX2 or a BBX–1X. If a cage has BBX–1X carriers, the redundant BBX (BBXR) must be a BBX–1X card to provide 1X redundancy support.

Site Equipage Verification

This section first verifies proper frame equipage. This includes verifying module placement, jumper, and dual in–line package (DIP) switch settings against the site-specific documentation supplied for each BTS application. Next, pre-power up and initial power-up procedures are presented.

Sites are configured as 3–sector with one or two carriers. Each type has unique characteristics and must be optimized accordingly.

The Cell-site Data File (CDF) contains site type and equipage data information and passes it directly to the CDMA Local Maintenance Facility (LMF) during optimization. The number of BTS frames, BBX2 and MCC24 boards, and linear power amplifier assignments are some of the equipage data included in the CDF.

Review the site documentation. Match the site engineering equipage data to the actual boards and modules shipped to the site. Physically inspect and verify the equipment provided for the frame.

CAUTION

Always wear a conductive, high impedance wrist strap while handling any circuit card/module to prevent damage by ESD. After removal, the card/module should be placed on a conductive surface or back into the anti–static bag it was shipped in.

Initial Installation of Boards/Modules

Table 2-1: Initial Installation of Boards/Modules

Step Action

1 Refer to the site documentation and, if it was not previously done, slide all boards and modules into

the appropriate shelves as required. DO NOT SEAT the boards and modules at this time.

2 As the actual site hardware is installed, record the serial number of each module on a “Serial Number

Checklist” in the site logbook.

Ethernet LAN

Ethernet LAN Termination

For proper operation, each end of the primary and redundant BTS Ethernet Local Area Networks (LAN) must be terminated with a 50–ohm load. For a BTS consisting of a single frame, this is done by placing 50–ohm triaxial terminations on the LAN A and B external IN and OUT connectors located in the power entry compartment (Figure 2-2). When the LAN links multiple frames in a logical BTS, the 50–ohm triaxial terminations must be installed on all uncabled LAN A and B external connectors on each frame.

Check the LAN A and B external IN and OUT connectors in the power entry compartment of each frame, and be sure terminations are installed on all the uncabled external LAN connectors.

! CAUTION

Using the incorrect type of power/converter modules will damage the module, the SCCP shelf, and other modules installed in the SCCP shelf.

* IMPORTANT

In the following steps, if the DMM reads between 300 Ω minimum and 900 Ω maximum after inserting any board/module, a low impedance problem probably exists in that board/module. Replace the suspect board/module and repeat the test. If test still fails, isolate the problem before proceeding.

Insert and lock the PS1 DC–DC converter module into its slot, and and turn ON the PS1 DC circuit breaker on the DC PDA.

10 Resistance between the MAP (–) VOLT TEST POINT and the (–) AMP TEST POINT should

typically increase as capacitors charge, finally measuring between 300 Ω minimum and 900 Ω. maximum.

to OFF.

Battery Charge T est (Connected Batteries)

Table 2-7 lists the step–by–step instructions for testing the battery charging performance.

Table 2-7: Battery Charge Test (Connected Batteries)

Step Action

1 Close the battery shelf circuit breakers (Figure 2-3) for connected batteries only. This process should

be completed quickly to avoid individual battery strings drawing excess charge current

NOTE

If the batteries are sufficiently discharged, the battery circuit breakers may not engage individually due to the surge current. If this condition occurs, disconnect the batteries from the 27Vdc bus by setting the MAP power switch to OFF, and then engage all the connected battery circuit breakers. The MAP power switch should then be turned ON.

Using the clamp–on DC current probe and DMM, measure the current in each of the battery string

connections to the battery bus bars. The charge current may initially be high but should quickly reduce in a few minutes if the batteries have a typical new–battery charge level.

NOTE

The MAP AMP display will indicate the total current output of the rectifiers during this procedure. As an alternative, the bar graph meters on the AC rectifier modules can be used as a rough estimate of

the total battery charge current. Each rectifier module bar graph has eight (8) LED elements to represent the output current. Each illuminated LED element indicates that approximately 12.5% (1/8 or 8.75 Amps) of an individual rectifier’s maximum current output (70 Amps) is flowing.

RECTIFIER BAR GRAPH EXAMPLE: Question: A system fitted with three (3) rectifier modules each have three bar graph LED elements

illuminated. What is the total output current into the batteries? Answer: Each bar graph is indicating approximately 12.5% of 70 amps, therefore, 3 x 8.75 equals

26.25 amps per rectifier. As there are three rectifiers, the total charge current is equal to (3 x 26.25 A)

78.75 amps. This charge current calculation is only valid when the RF and LPA compartment electronics are not

powered on, and the RF compartment heat exchanger is turned off. This can only be accomplished if the DC PDA MAIN BREAKER is set to OFF.

Step Action

3 The current in each string should be approximately equal (within + 5 amps). 4 Allow a few minutes to ensure that the battery charge current stabilizes before taking any further

action. Recheck the battery current in each string. If the batteries had a reasonable charge, the current in each string should reduce to less than 5 amps.

Recheck the DC output voltage. It should remain the same as measured in step 4 of the frame DC

Power Application and Test (Table 2-6).

NOTE

If discharged batteries are installed, the MAP AMP display may indicate approximately 288 amps for a two–carrier frame (four rectifiers) or 216 amps for a single–carrier frame (three rectifiers). Alternately, all bar graph elements may be lighted on the rectifiers during the charge test. Either indication shows that the rectifiers are at full capacity and are rapidly charging the batteries. It is recommended in this case that the batteries are allowed to charge and stabilize as in the above step before commissioning the site. This could take several hours.

Battery Discharge Test

Perform the test procedure in Table 2-8 only when the battery current is less than 5 Amps per string. Refer to Table 2-7 on the procedures for checking current levels.

Table 2-8: Battery Discharge Test

Step Action

1 Turn the BATT TEST switch on the MAP ON (Figure 2-9). The rectifier output voltage and current

should decrease by approximately 10% as the batteries assume the load. Alarms for the MAP may occur.

2 Measure the individual battery string current using the clamp–on DC current probe and DMM. The

battery discharge current in each string should be approximately the same (within +

3 Turn BATT TEST switch OFF.

CAUTION

Failure to turn off the MAP BATT TEST switch before leaving the site will result in low battery capacity and reduce battery life.

Optimization/Calibration – Introduction

Introduction

This chapter provides procedures for downloading system operating software, set up of the supported test equipment, CSM reference verification/optimization, and transmit/receive path verification.

IMPORTANT

Optimization Process Overview

After a BTS is physically installed and the preliminary operations, such as power up, have been completed, the CDMA LMF is used to calibrate and optimize the BTS. The basic optimization process consists of the following:

Before using the LMF, use an editor to view the ”CAVEATS” section in the ”readme.txt” file in the c:\wlmf folder for any applicable information.

S Download MGLI2 (GLI2–<bts#>–1) with application code and data

and then enable MGLI2.

S Use the CDMA LMF status function and verify that all of the installed

devices of the following types respond with status information: CSM2, BBX2, GLI2, and MCC (and TSU if RFDS is installed). If a device is installed and powered up but is not responding and is colored gray in the BTS display, the device is not listed in the CDF file. The CDF file will have to be corrected before the device can be accessed by CDMA LMF.

S Download device application code and data to all devices of the

following types:

– CSM2 – BBX2 – Remaining GLI2 (GLI2–<bts#>–2) – MCC

S Download the RFDS TSIC (if installed).

08/01/2001

S Verify the operation of the GPS and HSO signals. S Enable the following devices (in the order listed):

– Secondary CSM (slot 2) – Primary CSM (slot 1) – All MCCs

S Using the CDMA LMF test equipment selection function, select the

test equipment to be used for the calibration.

S Calibrate the TX and RX test cables if they have not previously been

calibrated using the CDMA LMF that is going to be used for the optimization/calibration. Cable calibration values can be entered manually, if required.

S Connect the required test equipment for a full optimization.

Optimization/Calibration – Introduction – continued

S Select all of the BBXs and all of the MCCs and use the full

optimization function. The full optimization function performs TX calibration, BLO download, TX audit, all TX tests, and all RX tests for all selected devices.

S If the TX calibration fails, repeat the full optimization for any failed

paths.

S If the TX calibration fails again, correct the problem that caused the

failure and repeat the full optimization for the failed path.

Cell Site Types

Cell Site Data File (CDF)

S If the TX calibration and audit portion of the full optimization passes

for a path but some of the TX or RX tests fail, correct the problem that caused the failure and run the individual tests as required until all TX and RX tests have passed for all paths.

Sites are configured as Omni/Omni or Sector/Sector (TX/RX). Each type has unique characteristics and must be optimized accordingly.

IMPORTANT

The CDF includes the following information:

Before using the CDMA LMF for optimization/ATP, the correct bts–#.cdf and cbsc–#.cdf files for the BTS must be obtained from the CBSC and put in a bts–# folder in the LMF. Failure to use the correct CDF files can cause unreliable or improper site operation. Failure to use the

correct CDF files to log into a live (traffic carrying) site can shut down the site.
