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:

S 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.

S not replace components with power cable connected. Under certain

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

S 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

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 covers the physical “bolt down” of all SC series equipment frames, and

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 ancillary equipment frame RFDS RX

directional coupler antenna feedline port and travels through the RX input port on the top of the frame, through the bandpass filter, MPC and additional splitter circuitry, ending at a Broad Band Transceiver (BBX) backplane slot in the CDMA Channel Processor (CCP) shelf.

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

through the BBX I/O to the TX Combiner, travels through the ELPA, and ends either at an antenna port on top of the frame or RFDS TX directional coupler antenna feedline port.

Six of the seven BBX2 boards in each S–CCP 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 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.

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.

T est 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.

T est 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 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 RFDS calibration procedures:

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

BTS Equipment Identification

Equipment Overview

The SC4812ETL BTS 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 220 Vac, rectified internally to +27 Vdc, and can support two carriers in a 3–sector configuration. An SC4812ETL starter frame with the maximum of one SC4812ETL expansion frame can support 4 carriers in a 3–sector configuration. Six– sector operation is not supported with any SC4812ETL configuration.

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

Logical BTS

A logical BTS can consist of up to two SC4812ETL frames. When the LMF is connected to frame 1 of a logical BTS, access is available to all devices in all of the frames that make up the logical BTS. A logical BTS CDF file that includes equippage information for all of the logical BTS frames and their devices is required. A CBSC file that includes channel data for all of the logical BTS frames is also required.

The first frame of a logical BTS has a –1 suffix (e.g., BTS–812–1) and the second frame of the logical BTS is numbered with the suffix, –101 (e. g. BTS–812–101). When the CDMA LMF is logged into a BTS, a FRAME tab is displayed for each frame. If there is only one frame for the BTS, there will only be one tab (e.g., FRAME–282–1 for BTS–282). If a logical BTS has more than one frame, there will be a separate FRAME tab for each frame (e.g. FRAME–438–1, and FRAME–438–101 for BTS–438 that has both frames). If an RFDS is included in the CDF file, an RFDS tab (e.g., RFDS–438–1) will be displayed.

Actions (e.g., ATP tests) can be initiated for selected devices in one or more frames of a logical BTS. Refer to the Select devices help screen for information on how to select devices.

Punch Block

The Punch Block is the interface between the cabinet and the T1/E1 span lines, the Customer I/O, alarms, multi–cabinet timing (RGPS and RHSO), and Pilot Beacon control (optional).

Span I/O Board

The Span I/O Board provides the interface for the span lines from the CSU to the SCCP backplane (see Figure 1-3).

RF Diagnostic Subsystem (RFDS)

The RFDS provides the capability for remotely monitoring the status of the SC4812ETL RF transmit and receive paths (Figure 1-6).

Heat Exchanger

The heat exchanger provides cooling to the cabinet RF compartment. The fan speed of the heat exchanger adjusts automatically with temperature. The heat exchanger is located in the cabinet main door.

SC4812ETL Interface Board (ETIB) and LPA Control (LPAC) Board

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

SC4812ETL Trunking Modules

The trunking modules contain a complex, passive RF network that allows RF signals to share the resources of a bank of four LPAs. They also provides DC power and digital interconnect (See Figure 1-3).

Batteries

The batteries provide +24Vdc backup to the cabinet should AC power be lost. The cabinet can accommodate a total of 12 12V batteries, configured in six series–connected strings of two batteries each. The time duration of backup provided depends on system configuration (See Figure 1-3).

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. The number of heaters is dependent on system configuration (See Figure 1-3).

1-20

Rectifiers

The rectifiers convert AC power supplied to the cabinet to +27Vdc to power the cabinet and maintain the charge of the backup batteries (See Figure 1-3).

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–sectored 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 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 BTS or Modem frame and ancillary equipment 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.

1 After cabinet AC input voltages are verified as correct, turn the Main AC breaker (located on the front

of the AC Load Center) ON. Observe that all eight (8) green LEDs on the front of the ACLC are illuminated (see Figure 2-4).

2 On the ACLC, Turn RECT. 1 and RECT. 2 AC branch breakers ON. All the installed rectifier

modules (see Figure 2-3) will start up, and the green DC and PWR LEDs should light on each.

3 Turn the Meter Alarm Panel module, ON (see Figure 2-6). The Meter Alarm Panel voltage meter

should read approximately 27.4 +

0.2 VDC.

4 Turn the Temperature Compensation Panel (TCP) ON, (see Figure 2-7). Verify that the Meter Alarm

Control Panel does not have any alarm LEDs illuminated.

5 Check the rectifier current bargraph displays (green LED display on the rectifier module). None

should be illuminated at this point.

NOTE

If batteries are fitted, turn on the two battery heater AC breakers on the AC Load Center.

Step Action

1 Ensure ALL DC PDA circuit breakers are OFF (pulled out). 2 Be sure the procedures in Table 2-4 (if required) and (Table 2-5) have been performed. 3 Probe the VOLT TEST POINTS on the Meter Alarm Panel while pressing the 25° C set button on the

TCP (see Figure 2-7). The voltage should read 27.4 +

0.2 VDC. Adjust Master Voltage on Meter

Alarm Panel if necessary. Release the TCP 25° C set button.

4 Depending on the ambient temperature, the voltage reading may now change by up to + 1.5 V

compared to the reading just measured. If it is cooler than 25_C, the voltage will be higher, and if it is warmer than 25_C, the voltage will be lower.

5 If the BTS is equipped with a internal backup batteries, close (push in) DC PDA Main Breaker #1

(Internal) and proceed to step 7.

6 If the BTS is connected to an external BOE containing backup batteries, close (push in) DC PDA

Main Breaker #2 (External).

7 Inside the power entry compartment at the rear of the cabinet, measure the voltage between the + (red)

terminals of the filtered DC battery compartment feedthrough (Figure 2-2) and chassis ground, observing that the polarity is correct. The voltage should be the same as the measurement in step 2.

8 Measure the voltage between the + (red) and – (black) battery bus bars in the battery compartment.

Place the probe at the bottom of the bus bars where the cables are connected. The DC voltage should measure the same as the previous step.

9 On the DC PDA(see Figure 2-5) set the circuit breakers to the ON position by pushing them in one at

a time in the following sequence:

S PS1 and PS2 circuit breakers S LPA circuit breakers (four breakers, labeled 1A–1B through 2C–2D). S HEAT EXCHANGER circuit breakers (two breakers) S ETIB circuit breaker S PILOT BEACON circuit breaker S OPTION circuit breaker

Battery Charge T est (Connected Batteries)

Table 2-7 lists the step–by–step instructions for testing the batteries.

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 with 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 is observed, turn off the Meter Alarm Panel power switch, and then engage all the connected battery circuit breakers, the Meter Alarm Panel power switch should then be turned ON.

Using the DC current probe, measure the current in each of the battery string connections to the

battery cabinet 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 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) LEDs to represent the output current. Each illuminated LED indicates that approximately 12.5% (1/8 or 8.75 Amps) of the rectifiers maximum (70 Amps) current is flowing.

EXAMPLE: Question: A system fitted with three (3) rectifier modules each have three bargraph LEDs

illuminated. What is the total output current into the batteries? Answer: Each bargraph is approximately indicating 12.5% of 70 Amps, therefore, 3 X 8.75 equals

26.25 Amps. As there are three rectifiers, the total charge current is equal to (3 X 26.25 A) 78.75 Amps.

This charge current calculation only applies at this part of the start up procedure, when the RF Cabinet is not powered on, and the power cabinet heat exchanger is turned off.

3 The current in each string should be approximately equal (+ 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 5A.

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

Test.

NOTE

If discharged batteries are installed, all bargraphs may be illuminated on the rectifiers during the charge test. This indicates 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.

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

After a BTS is physically installed and the preliminary operations (power up) have been completed, the CDMA LMF is used to calibrate and optimize the BTS. The basic optimization process can be accomplished as follows:

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 MGLI2–1 with code and data and then enable MGLI2–1. S Use the 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 code and data to all devices of the following types:

– CSM2 – BBX2 – GLI2 (other than MGLI2–1) – MCC

08/15/2000

S Download the RFDS TSIC (if installed). 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 Connect the required test equipment for a full optimization. S Select the test equipment. 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. The cable calibration values can also be entered manually.

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.

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.

The CDF includes the following information:

S Download instructions and protocol S Site specific equipage information S C–CCP shelf allocation plan

– BBX2 equipage (based on cell–site type) including redundancy – CSM equipage including redundancy – Multi Channel Card 24 (MCC24 or MCC8E) channel element

allocation plan. This plan indicates how the C–CCP shelf is configured, and how the paging, synchronization, traffic, and access channel elements (and associated gain values) are assigned among the (up to 12) MCC24s or MCC8Es in the shelf.

Pre–Optimization: Introduction – continued

BTS System Software Download

BTS system software must be successfully downloaded to the BTS processor boards before optimization can be performed. BTS operating code is loaded from the LMF computer terminal.

IMPORTANT

Site Equipage Verification

The CDF is normally obtained from the CBSC on a DOS formatted diskette, or through a file transfer protocol (ftp) if the LMF computer has ftp capability. Refer to the CDMA LMF Operator’s Guide, 68P64114A21, or the LMF Help screen, for more information.

If you have not already done so, use an editor to view the CDF, and review the site documentation. Verify the site engineering equipage data in the CDF to the actual site hardware.

Before using the 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 wrong results. Failure to use the correct CDF files to log into a live (traffic carrying) site can shut down the site.

CAUTION

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

Span Lines – Interface and Isolation

Isolate BTS from T1/E1 Spans

IMPORTANT

Configure Channel Service Unit

Each frame is equipped with one 50 pair punch block for spans, customer alarms, remote GPS, and power cabinet alarms. See Figure 3-2 and refer to Table 3-1 for the physical location and pin call–out information. To disable the span, pull the surge protectors for the respective span.

Before connecting the LMF to the frame LAN, the OMC/CBSC must disable the BTS and place it OOS to allow the LMF to control the BTS. This prevents the CBSC from inadvertently sending control information to the BTS during LMF based tests.

The M–PATH 537 channel service unit (CSU) provides in–band SNMP–managed digital service access to T1 and fractional T1 lines. M–PATH units plug into the ADC Kentrox 2–slot frame (see Figure 3-1).

Remote M–PATH management is available via SNMP over an in–band data link on the T1 line (using a facility data link or 8–64 Kbps of a DS0 channel). The unit at the near end of the management path can be an SNMP manager or another M–PATH CSU.

At active sites, the OMC/CBSC must disable the BTS and place it out of service (OOS). DO NOT remove the span surge protectors until the OMC/CBSC has disabled the BTS.

3-4

Each 19 inch rack can support two CSU M–PATH 537 modules. Each M–PATH 537 module supports a single span connection.

Programming of the M–PATH is accomplished through the DCE 9–pin connector on the front panel of the CSU shelf. Manuals and a Microsoft Windows programming disk is supplied with each unit.

Overview

Before optimization can be performed, the CDMA LMF must be installed and configured on a computer platform meeting Motorola–specified requirements (see Recommended Test Equipment and Software in Chapter 1).

IMPORTANT

Software and files for installing and updating the CDMA LMF are provided on CD ROM disks. The following items must be available:

For the CDMA LMF graphics to display properly, the computer platform must be configured to display more than 256 colors. See the operating system software instructions for verifying and configuring the display settings.

S CDMA LMF Program on CD ROM S CDMA LMF Binaries on CD ROM S Configuration Data File (CDF) for each supported BTS (on floppy

disk)

S CBSC File for each supported BTS (on floppy disk)

The following section provides information and instructions for installing and updating CDMA LMF software and files.

Copy CBSC CDF Files to the LMF Computer

Table 3-3: CD ROM Installation

Before logging on to a BTS with the CDMA LMF computer to execute optimization/ATP procedures, the correct bts-#.cdf and

cbsc-#.cdf files must be obtained from the CBSC and put in a bts-# folder in the CDMA LMF computer. This requires creating

versions of the CBSC CDF files on a DOS–formatted floppy diskette and using the diskette to install the CDF files on the CDMA LMF computer.

IMPORTANT

When copying CDF files, comply with the following to prevent BTS login problems with the Windows LMF:

S The numbers used in the bts-#.cdf and

cbsc-#.cdf filenames must correspond to the

locally–assigned numbers for each BTS and its controlling CBSC.

S The generic cbsc–1.cdf file supplied with the Windows

LMF will work with locally numbered BTS CDF files. Using this file will not provide a valid optimization unless the generic file is edited to replace default parameters (e.g., channel numbers) with the operational parameters used locally.

The procedure in Table 3-4 lists the steps required to transfer the CDF files from the CBSC to the CDMA LMF computer. For any further information, refer to the CDMA LMF Operator’s Guide (Motorola part no. 68P64114A21) or the CDMA LMF Help screen.

NOTE

S Other versions of Unix do not support the unix2dos and dos2unix commands. In these cases, use

the Unix cp (copy) command. The copied files will be difficult to read with a DOS or Windows text editor because Unix files do not contain line feed characters. Editing copied CDF files on the CDMA LMF computer is, therefore, not recommended.

S Using cp, multiple files can be copied in one operation by separating each filename to be copied

with a space and ensuring the destination directory (floppy/no_name) is listed at the end of the command string following a space (e.g., cp bts–248.cdf cbsc–6.cdf /floppy/no_name).

8 Repeat steps 5 through 7 for each bts–# which must be supported by the CDMA LMF computer. 9 When all required files have been copied to the diskette type eject and press the Enter key.

Creating a Named HyperTerminal Connection for MMI Communication

Table 3-5: Create HyperTerminal Connection

Confirming or changing the configuration data of certain BTS Field Replaceable Units (FRU) requires establishing an MMI communication session between the CDMA LMF computer and the FRU. Using features of the Windows operating system, the connection properties for an MMI session can be saved on the CDMA LMF computer as a named Windows HyperTerminal connection. This eliminates the need for setting up connection parameters each time an MMI session is required to support optimization.

Once the named connection is saved, a shortcut for it can be created on the Windows desktop. Double–clicking the shortcut icon will start the connection without the need to negotiate multiple menu levels.

Follow the procedures in Table 3-5 to establish a named HyperTerminal connection and create a Windows desktop shortcut for it.

Using CDMA LMF

Basic CDMA LMF Operation

The CDMA LMF allows the user to work in the two following operating environments which are accessed using the specified desktop icons:

S Graphical User Interface (GUI) using the WinLMF icon S Command Line Interface (CLI) using the WinLMF CLI icon

The GUI is the primary optimization and acceptance testing operating environment. The CLI environment provides additional capability to the user to perform manually controlled acceptance tests and audit the results of optimization and calibration actions.

Basic operation of the CDMA LMF in either environment includes performing the following:

S Selecting and Deselecting BTS devices S Enabling devices S Disabling devices S Resetting devices S Obtaining device status

Logging Into a BTS

The following additional basic operation can be performed in a GUI environment:

S Sorting a status report window

For detailed information on performing these and other CDMA LMF operations, refer to the CDMA LMF Operator’s Guide – 68P64114A21.

IMPORTANT

Unless otherwise noted, LMF procedures in this manual are performed using the GUI environment.

WARNING

Be sure that the correct bts–#.cdf and cbsc–#.cdf file is used for the BTS. These should be the CDF files that are provided for the BTS by the CBSC. Failure to use the correct CDF files can result in invalid optimization.

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

Pinging the Processors

Pinging the BTS

For proper operation, the integrity of the Ethernet LAN A and B links must be be verified. NO TAG represents a typical BTS Ethernet configuration. The drawing depicts one (of two identical) links, A and B.

Ping is a program that sends request packets to the LAN network modules to get a response from the specified “target” module.

Follow the steps in Table 3-12 to ping each processor (on both LAN A and LAN B) and verify LAN redundancy is working properly.

CAUTION

Always wear a conductive, high impedance wrist strap while handling any circuit card/module to prevent damage by ESD.

Download the BTS

Overview

Before a BTS can operate, each equipped device must contain device initialization (ROM) code. ROM code is loaded in all devices during manufacture or factory repair. Device application (RAM) code and data must be downloaded to each equipped device by the user before the BTS can be made fully functional for the site where it is installed.

ROM Code

Downloading ROM code to BTS devices from the CDMA LMF is NOT routine maintenance or a normal part of the optimization process. It is

only done in unusual situations where the resident ROM code in the device does not match the release level of the site operating software AND the CBSC can not communicate with the BTS to perform the download. An example would be a BTS loaded with Release 9.2 software where a GLI loaded with Release 2.8.1 ROM code must be installed to replace a malfunctioning MGLI.

Before ROM code can be downloaded from the CDMA LMF, the correct ROM code file for each device to be loaded must exist on the LMF computer. ROM code must be manually selected for download.

ROM code can be downloaded to a device that is in any state. After the download is started, the device being downloaded will change to OOS–ROM (blue). The device will remain OOS–ROM (blue) when the download is completed. The same Revision–level RAM code must then be downloaded to the device. For example, if Release 2.9.2.1.1 ROM code is downloaded, Release 2.9.2.1.1 RAM code must be downloaded.

Procedures to load ROM code are located in Appendix G.

RAM Code

3-30

Before RAM code can be downloaded from the CDMA LMF, the correct RAM code file for each device must exist on the LMF computer. RAM code can be automatically or manually selected depending on the Device menu item chosen and where the RAM code file for the device is stored in the CDMA LMF file structure. The RAM code file will be selected automatically if the file is in the \lmf\cdma\loads\n.n.n.n\code folder (where n.n.n.n is the version number of the download code that matches the “NextLoad” parameter of the CDF file). The RAM code file in the code folder must have the correct hardware bin number.

RAM code can be downloaded to a device that is in any state. After the download is started, the device being loaded will change to OOS-ROM (blue). When the download is completed successfully, the device will change to OOS-RAM (yellow). When code is downloaded to an MGLI or GLI, the CDMA LMF automatically also downloads data and then enables the MGLI. When enabled, the MGLI will change to INS (green).

For non–GLI devices, data must be downloaded after RAM code is downloaded. To download data, the device state must be OOS–RAM (yellow).

SC 4812ETL BTS Optimization/ATP

The devices to be loaded with RAM code and data are:

S Master Group Line Interface (MGLI2) S Redundant GLI (GLI2) S Clock Syncronization Module (CSM) (Only if new revision code must

be loaded)

S Multi Channel CDMA (MCC24) card S Broadband Transceiver (BBX2) S RFDS Test Subscriber Interface Card (TSIC), if equipped

IMPORTANT

RAM code downloading requires a few minutes. After the download starts, the non–GLI device being loaded changes to OOS–ROM (blue). If the download is completed successfully, the non–GLI device changes to OOS–RAM (yellow).

The MGLI must be successfully downloaded with RAM code and data, and in INS (green) status before downloading any other device. The RAM code download process for an MGLI automatically downloads data and then enables the MGLI.

Download RAM Code and Data to MGLI and GLI

Follow the steps outlined in Table 3-13 to download the RAM code and data to the MGLI and other installed GLI devices.

CAUTION

Release 2.9.x RAM code must NOT be downloaded to a device loaded with Release 2.8.x ROM code, and Release

2.8.x RAM code must NOT be downloaded to a device loaded with Release 2.9.x ROM code.

All devices in a BTS must have the same Release–level ROM and RAM code before the optimization and ATP procedures can be performed.

If a newly–installed Release 8–equipped BTS is to be upgraded to Release 2.9.x, the optimization and Acceptance Test Procedures (ATP) should be accomplished with the Release 2.8.x code and software. Following the optimization, the site code and software should be upgraded to Release 2.9.x by the CBSC. It is not necessary to perform the optimization and ATPs again after the upgrade.

If a replacement device with Release 2.8.x ROM code must be used in a Release 2.9.x–equipped BTS, the device ROM code can be changed using the CDMA LMF before the performing the BTS optimization and ATPs. A device

loaded with Release 2.9.x ROM code can not be converted back to Release 2.8.x ROM code in the field without Motorola assistance.

Prerequisites

S Prior to performing these procedures, ensure a code file exists for each

of the devices to be loaded.

S The CDMA LMF computer is connected to the BTS (refer to

Table 3-6), and is logged in using the GUI environment (refer to Table 3-7).

Each BTS CSM system features two CSM boards per site. In a typical operation, the primary CSM locks its Digital Phase Locked Loop (DPLL) circuits to GPS signals. These signals are generated by either an on–board GPS module (RF–GPS) or a remote GPS receiver (R–GPS). The GPS receiver interfaced to CSM 1 is used as the primary timing reference and synchronizes the entire cellular system. CSM 2 provides clock syncronization redundancy, but does not have a GPS receiver.

The BTS may be equipped with a LORAN–C Low Frequency Receiver (LFR) High Stability Oscillator (HSO), or external 10 MHz Rubidium source which the CSM can use as a secondary timing reference. In all cases, the CSM monitors and determines what reference to use at a given time.
