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.

Ancillary Equipment Frame Identification

NOTE

BTS Frame Description

Equipment listed below can be wall mounted or mounted in a standard 19 inch frame. The description assumes that all equipment is mounted in a frame for clarity.

If equipped with the RF Diagnostic Subsystem (RFDS) option, the RFDS and directional couplers are the interface between the site antennas and the BTS or Modem frame. The RFDS equipment includes:

 Directional couplers  Site receive bandpass/bandreject filters  RFDS

The BTS is the interface between the span lines to/from the Cellsite Base Station Controller (CBSC) and the site antennas. This frame is described in three sections:

 The top interconnect plate where all connections are made.  The upper portion of the frame which houses circuit breakers, cooling

fans, and the Combined CDMA Channel Processor (C–CCP) shelf.

 The lower portion of the frame which houses the LPA fans, LPAs, and

TX filter/combiners.

1-12

 The –48 V version of the BTS also has a section below the LPAs

containing a power conversion shelf that supplies power to the LPAs.

Use the illustrations that follow to visually identify the major components, that make up the Motorola SC 4812T BTS frame.

There are a number of ways to configure the BTS frame. Table 1-1 outlines the basic requirements. When carrier capacity is greater than two, a 2:1 or 4:1 cavity combiner must be used. For one or two carriers, bandpass filters or cavity combiners may be used, depending on sectorization and channel sequencing.

Preliminary Operations: Overview

Introduction

Cell Site Types

CDF

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 Omni with a maximum of 4 carriers, 3–sectored with a maximum of 4 carriers, and 6–sectored with a maximum of 2 carriers. Each type has unique characteristics and must be optimized accordingly. For more information on the differences in site types, please refer to the BTS/Modem Frame Hardware Installation manual.

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 modem frames, C–CCP shelves, BBX2 boards, MCC24/MCC8E boards (per cage), and linear power amplifier assignments are some of the equipage data included in the CDF.

IMPORTANT

Be sure that the correct bts–#.cdf and cbsc–#.cdf files are 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 cause system errors. Failure to use

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

Site Equipage Verification

Initial Installation of Boards/Modules

May 2000

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 shipping bag.

Follow the procedure in Table 2-1 to verify the initial installation of boards/modules.

Optimization/Calibration – Introduction

Introduction

This section describes procedures for downloading system operating software, CSM reference verification/optimization, set up and calibration of the supported test equipment, transmit/receive path verification, and using the RFDS.

IMPORTANT

Optimization Process

After a BTS is physically installed and the preliminary operations (power up) have been completed, the LMF is used to calibrate and optimize the BTS. Motorola recommends that the optimization be accomplished as follows:

1. Download MGLI2–1 with code and data and then enable MGLI2–1.

2. Use the status function and verify that all of the installed devices of the following types respond with status information: CSM, 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 the LMF.

3. Download code and data to all devices of the following types:

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

4. Download the RFDS TSIC (if installed).

5. Verify the operation of the GPS and HSO signals.

6. Enable the following devices (in the order listed):

– Secondary CSM – Primary CSM – All MCCs

7. Connect the required test equipment for a full optimization.

8. Select the test equipment.

9. 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.

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.

Optimization/Calibration – Introduction – continued

10. 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.

11. If the TX calibration fails, repeat the full optimization for any failed paths.

12. 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

13. 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.

NOTE

Cell Site Data File (CDF)

For more information on the differences in site types, please refer to the applicable BTS/Modem Frame Hardware

Installation and Functional Hardware Description

manuals.

The CDF contains information that defines the BTS and data used to download files to the devices. A CDF file must be placed in the applicable BTS folder before the LMF can be used to log into that BTS. CDF files are normally obtained from the CBSC using a floppy disk. A file transfer protocol (ftp) method can be used if the LMF computer has that capability.

The CDF includes the following information:

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

– BBX2 equipage (based on cell–site type) including redundancy – CSM equipage including redundancy – Multi Channel Card (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.

Optimization/Calibration – Introduction – continued

 Effective Rated Power (ERP) table for all TX channels to antennas

respectively. Motorola System Engineering specifies the ERP of a transmit antenna based on site geography, antenna placement, and government regulations. Working from this ERP requirement, the antenna gain, (dependent on the units of measurement specified) and antenna feed line loss can be combined to determine the required power at the top of the BTS frame. The corresponding BBX2 output level required to achieve that power level on any channel/sector can also be determined.

NOTE

Refer to the CDMA LMF Operator’s Guide, 68P64114A21, for additional information on the layout of the LMF directory structure (including CDF file locations and formats).

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.

Site Equipage Verification

IMPORTANT

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, or the LMF Help screen, for the procedure.

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 matches the actual site hardware using a CDF conversion table.

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.

Isolate Span Lines/Connect LMF

Isolate BTS from T1/E1 Spans

IMPORTANT

At active sites, the OMC/CBSC must disable the BTS and place it out of service (OOS). DO NOT remove the 50–pin TELCO cable connected to the BTS frame site I/O board J1 connector until the OMC/CBSC has disabled the BTS!

Each frame is equipped with one Site I/O and two Span I/O boards. The Span I/O J1 connector provides connection of 25 pairs of wire. 8 pairs are used to support up to four 4–wire span lines. 17 pairs are connected to signal ground.

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 CDMA BTS. This prevents the CBSC from inadvertently sending control information to the CDMA BTS during LMF based tests. Refer to Figure 3-1 and Figure 3-2 as required.

Table 3-1: T1/E1 Span Isolation

Step Action

1 From the OMC/CBSC, disable the BTS and place it OOS. Refer to SC OMC–R/CBSC System

Operator Procedures.

– The T1/E1 span 50–pin TELCO cable connected to the BTS frame SPAN I/O board J1 connector

can be removed from both Span I/O boards, if equipped, to isolate the spans.

* IMPORTANT

Verify that you remove the SPAN cable, not the “MODEM/TELCO” connector.

LMF to BTS Connection

The LMF is connected to the LAN A or B connector located on the left side of the frame’s lower air intake grill, behind the LAN Cable Access door (see Figure 3-2).

Table 3-2: LMF to BTS Connection

Step Action

1 To gain access to the connectors on the BTS, open the LAN Cable Access door, then pull apart the

Velcro tape covering the BNC “T” connector (see Figure 3-2).

2 Connect the LMF to the LAN A BNC connector via PCMCIA Ethernet Adapter with an unshielded

twisted–pair (UTP) Adapter and 10BaseT/10Base2 converter (powered by an external AC/DC transformer).

NOTE

– Xircom Model PE3–10B2 or equivalent can also be used to interface the LMF Ethernet

connection to the frame connected to the PC parallel port, powered by an external AC/DC transformer. In this case, the BNC cable must not exceed 91 cm (3 ft) in length.

* IMPORTANT

– The LAN shield is isolated from chassis ground. The LAN shield (exposed portion of BNC

connector) must not touch the chassis during optimization.

Preparing the LMF

Overview

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

 LMF Program on CD ROM  LMF Binaries on CD ROM  Configuration Data File (CDF) for each supported BTS (on diskette or

Graphical User Interface Overview

available from the CBSC)

 CBSC File for each supported BTS (on diskette or available from the

CBSC)

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

The LMF uses a graphical user interface (GUI), which works in the following way:

Logical BTS

 Select the device or devices.  Select the action to apply to the selected device(s).  While action is in progress, a status report window displays the action

taking place and other status information.

 The status report window indicates when the the action is complete

and displays other pertinent information.

 Clicking the OK button closes the status report window.

The BTS software implements the logical BTS capability, also known as virtual BTS. Previously, all BTS frames co–located at a single site had to be identified in the network with separate and distinct BTS ID numbers. In the Logical BTS feature, all frames located at a single BTS site are identified with unique Frame ID numbers (Frame ID Numbers 1, 101, 201, 301) under a single (site) BTS ID number. A logical BTS can consist of up to four SC 4812T frames.When the LMF is connected to frame 1 of a logical BTS, you can access all devices in all of the frames that make up the logical BTS. A logical BTS requires a CDF file that includes equipage information for all of the logical BTS frames and their devices and a CBSC file that includes channel data for all of the logical BTS fames.

Logical BTS Numbering

The first frame of a logical BTS has a –1 suffix (e.g., BTS–812–1). Other frames of the logical BTS are numbered with suffixes, –101, –201, and –301 (e. g. BTS–812–201). When you log into a BTS, a FRAME tab is displayed for each frame. If there is only one frame for the BTS, there is only one tab (e.g., FRAME–282–1) for BTS–282. If a logical BTS has more than one frame, there is a separate FRAME tab for each frame (e.g. FRAME–438–1, FRAME–438–101, and FRAME–438–201 for a BTS–438 that has three frames). If an RFDS is included in the CDF file, an RFDS tab (e.g., RFDS–438–1) is displayed. Figure 3-3 shows frame configurations available under the Logical BTS feature. This figure also shows the Inter–frame spans between the different frames at the BTS site.

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.

C–CCP Shelf Card/Module Device ID Numbers

All cards/modules/boards in the frames at a single site, assigned to a single BTS number, are also identified with unique Device ID numbers dependent upon the Frame ID number in which they are located. Refer to Table 3-3 and Table 3-4 for specific C–CCP Shelf Device ID numbers.

Program and Binaries Update Procedure

Follow the procedure in Table 3-5 to update the LMF program and binaries.

NOTE

First Time Installations: – Install Java Runtime Environment (First) – Install LMF Software (Second) – Install BTS Binaries (Third) – Install/Create BTS Folders (Fourth)

NOTE

If applicable, a separate CD ROM of BTS Binaries may be available for binary updates.

Table 3-5: CD ROM Installation

 Step Action

1 Insert the LMF Program CD ROM into the LMF CD ROM drive.

– If the Setup screen is displayed, follow the instructions provided. – If the Setup screen is not displayed, proceed to step 2.

2 Click on the Start button. 3 Select Run. 4 In the Open box, enter d:\autorun and click on the OK button.

NOTE

If applicable, replace the letter d with the correct CD ROM drive letter.

5 Follow the instructions displayed in the Setup screen.

Copy CDF Files from CBSC

Before the LMF can execute the optimization/ATP procedures for the BTS, the correct bts-#.cdf and cbsc-#.cdf files must be obtained from the CBSC and put in a bts-# folder in the LMF notebook. This requires copying the CBSC CDF files to a DOS formatted diskette, and using the diskette to install the CDF file in the LMF.

. . . continued on next page

May 2000

SC 4812T CDMA BTS Optimization/ATP

Preparing the LMF – continued

Follow the procedure in Table 3-6 to obtain the CDF files from the CBSC and copy the files to a diskette. For any further information, refer to the CDMA LMF Operator’s Guide (Motorola part number 68P64114A21) or the LMF Help screen..

NOTE

If the LMF has ftp capability, the ftp method can be used to copy the CDF files from the CBSC.

On Sun OS workstations, the unix2dos command can be used in place of the cp command (e.g., unix2dos bts–248.cdf bts–248.cdf). This should be done using a copy of the CBSC CDF file so the original CBSC CDF file is not changed to DOS format.

IMPORTANT

Table 3-6: Copying CBSC CDF Files to the LMF

 Step Action

AT THE CBSC:

1 Login to the CBSC workstation. 2 Insert a DOS formatted diskette in the workstation drive.

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

– 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.

– The generic cbsc–1.cdf file supplied with the LMF work with locally numbered BTS CDF files. Using this file does 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.

3-10

3 Type eject –q and press the <Enter> key. 4 Type mount and press the <Enter> key.

NOTE

 Look for the “floppy/no_name” message on the last line displayed.  If the eject command was previously entered, floppy/no_name will be appended with a number.

Use the explicit floppy/no_name reference displayed when performing step 7.

Table 3-6: Copying CBSC CDF Files to the LMF

 ActionStep

5 Change to the directory containing the file by typing cd <directoryname> (ex. cd bts–248) and

pressing <Enter>. 6 Type ls <Enter> to display the list of files in the directory. 7 With Solaris versions of Unix, create DOS–formatted versions of the bts–#.cdf and cbsc–#.cdf

files on the diskette by entering the following command:

unix2dos <source filename> /floppy/no_name/<target filename>

(e.g., unix2dos bts–248.cdf /floppy/no_name/bts–248.cdf).

NOTE

 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 LMF computer is, therefore, not recommended.

 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/na_name)

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

10 Remove the diskette from the CBSC.

AT THE LMF:

11 Start the Windows operating system. 12 Insert the diskette into the LMF. 13 Using Windows Explorer (or equivalent program), create a corresponding bts–# folder in the

wlmf\cdma directory for each bts–#.cdf/cbsc–#.cdf file pair copied from the CBSC.

14 Use Windows Explorer (or equivalent program) to transfer the cbsc–#.cdf and bts–#.cdf files from

the diskette to the corresponding wlmf\cdma\bts–# folders created in step 13.

Creating a Named HyperTerminal Connection for MMI Connection

Confirming or changing the configuration data of certain BTS Field Replaceable Units (FRUs) requires establishing an MMI communication session between the LMF and the FRU. Using features of the Windows operating system, the connection properties for an MMI session can be saved on the 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.

 Step Action

1 If you have not already done so, connect the LMF to the BTS (see Table 3-2 on page 3-5). 2 From the Windows desktop, click the Start button and select Run. 3 In the Open box, type ping and the MGLI IP address (for example, ping 128.0.0.2).

NOTE

128.0.0.2 is the default IP address for MGLI–1 in field BTS units. 128.0.0.1 is the default IP address for MGLI–2.

4 Click on the OK button. 5 If the connection is successful, text similar to the following is displayed:

Reply from 128 128.0.0.2: bytes=32 time=3ms TTL=255

If there is no response the following is displayed:

Request timed out

If the MGLI fails to respond, reset and perform the ping process again. If the MGLI still fails to respond, typical problems are shorted BNC to inter-frame cabling, open cables, crossed A and B link cables, missing 50–Ohm terminators, or the MGLI itself.

Logging into a BTS

Logging into a BTS establishes a communications link between the BTS and the CDMA LMF. You may be logged into one or more BTS’s at a time, but only one LMF may be logged into each BTS.

IMPORTANT

Before attempting to log into the BTS, confirm the LMF is properly connected to the BTS (see Figure 3-2). Follow the procedure in Table 3-9 to log into a BTS.

Prerequisites

Before attempting to login to a BTS, ensure the following have been completed:

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 wrong results. Failure to

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

 A bts-nnn folder with the correct CDF file and CBSC file exists.  The LMF is correctly installed and prepared, and the LMF computer

was connected to the BTS before starting the Windows operating system and LMF software. If necessary, restart the computer after connecting it to the BTS (see Table 3-2 and Figure 3-2).

Table 3-9: BTS Login Procedure

 Step Action

1 Click on the Login tab (if not displayed). 2 If no base stations can be seen, double click on CDMA (in the Available base Stations pick list). 3 Click on the desired BTS number. 4 Click on the Network Login tab (if not already in the forefront). 5 Enter correct IP address (normally 128.0.0.2) for a field BTS, if not correctly displayed in the IP

Address box.

NOTE

128.0.0.2 is the default IP address for MGLI–1 in field BTS units. 128.0.0.1 is the default IP address for MGLI–2.

6 Type in the correct IP Port number (normally 9216) if not correctly displayed in the IP Port box. 7 Change the Multi-Channel Preselector (from the Multi-Channel Preselector pick list), normally

MPC, corresponding to your BTS configuration, if required.

8 Click on the Use a Tower Top Amplifier, if applicable.

Download the BTS

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 LMF is NOT routine maintenance nor 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 (e.g., Release 8.x ROM code and Release 9.x software) AND the CBSC cannot communicate with the BTS to perform the download. If you must download ROM code, refer to Appendix H.

Before ROM code can be downloaded from the 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.

RAM Code

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 is 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). The RAM code file in the code folder must have the correct hardware bin number.

May 2000

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

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

SC 4812T CDMA BTS Optimization/ATP

Download the BTS – continued

Download Code to Devices

Code can be downloaded to a device that is in any state. After the download starts, the device being downloaded changes to OOS_ROM (blue). If the download is completed successfully, the device changes to OOS_RAM with code loaded (yellow). Prior to downloading a device, a code file must exist. The code file is selected automatically if the code file is in the /lmf/cdma/n.n.n.n/code folder (where n.n.n.n is the version number of the download code that matches the “NextLoad”

parameter in the CDF file). The code file in the code folder must have the correct hardware bin number. Code can be automatically or manually selected.

The following are the devices to be downloaded:

 Span Configuration

– Master Group Line Interface (MGLI2) – Slave Group Line Interface (SGLI2)

 Clock Synchronization Module (CSM)  Multi Channel Card (MCC24 or MCC8E)  Broadband Transceiver (BBX2)  Test Subscriber Interface Card (TSIC) – if RFDS is installed

IMPORTANT

Follow the procedure in Table 3-11 to download the firmware application code for the MGLI2. The download code action downloads data and also enables the MGLI2.

Prerequisite

Prior to performing this procedure, ensure a code file exists for each of the devices to be downloaded.

The MGLI must be successfully downloaded with code and data, and put INS before downloading any other device. The download code process for an MGLI automatically downloads data and enables the MGLI before downloading other devices. The other devices can be downloaded in any order.
