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, BBX boards, MCC 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

Mar 2001

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 isolating the BTS from the span lines, preparing and using the LMF, downloading system operating software, CSM reference verification/optimization, set up and calibration of the supported test equipment, transmit/receive path verification, using the RFDS, and verifying the customer defined alarms and relay contacts are functioning properly.

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, BBX, GLI2, 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 – BBX (may be BBX2 or BBX–1X) – GLI2 (other than MGLI2–1) – MCC (may be MCC–8E, MCC24, or MCC–1X)

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

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 Cell–SiteData File (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

– BBX equipage (based on cell–site type) including redundancy – CSM equipage including redundancy – MCC (MCC24E, MCC8E, or MCC–1X) 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) MCCs in the shelf.

 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 BBX 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, 68P64114A78, 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

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.

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. A GLI2 card can support up to six spans. In the SC 4812T configuration, the odd spans (1, 3, and 5) terminate on the Span ”A” I/O; and the even spans (2, 4, and 6) terminate on the Span ”B” I/O.

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

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!

NOTE

If a third party is used for span connectivity, the third party must be informed before disconnecting the span line.

* 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).

– If there is no login response, connect the LMF to the LAN B connector. – If there is still no login response, see Table 6-1, Login Failure Troubleshooting Procedures.

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  CDF for each supported BTS (on diskette or 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.

IMPORTANT

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.

Table 3-3: LMF Operating System Installation

 ActionStep

5 Follow the instructions displayed on the Setup screen.

* IMPORTANT

First Time Installations:

– Install U/WIN (First)

– Install Java Runtime Environment (Second) – Install LMF Software (Third) – Install BTS Binaries (Fourth) – Install/Create BTS Folders (Fifth)

Any time you install U/WIN, you must install the LMF software because the installation of the LMF modifies some of the files that are installed during the U/Win installation. Installing U/Win over–writes these modifications.

NOTE

There are multiple binary image packages for installation on the CD–ROM. When prompted, choose the load that corresponds to the switch release that you currently have installed. Perform the Device Images install after the WinLMF installation.

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

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.

Follow the procedure in Table 3-4 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 68P64114A78) 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 3-4: 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 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.

5 Change to the directory containing the file by typing cd <directory name> (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).

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.

3-10

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 procedure in Table 3-5 to establish a named HyperTerminal connection and create a WIndows desktop shortcut for it.

NOTE

There are differences between Windows NT and Windows 98 in the menus and screens for creating a HyperTerminal connection. In the following procedure, items applicable to:

– Windows NT will be identified with Win NT – Windows 98 will be identified with Win 98

Using CDMA LMF

Basic LMF Operation

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

 Graphical User Interface (GUI) using the WinLMF icon  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 LMF GUI includes the following:

 Selecting and deselecting BTS devices  Enabling devices  Disabling devices  Resetting devices  Obtaining device status  Sorting a status report window

For detailed information on performing these and other LMF operations, refer to the CDMA LMF Operator’s Guide, 68P64114A78.

Graphical User Interface Overview

The LMF uses a GUI, which works in the following way:

 Select the device or devices.  Select the action to apply to the selected device(s).

3-18

 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.

Using CDMA LMF – continued

Command Line Interface Overview

The LMF also provides Command Line Interface (CLI) capability. Activate the CLI by clicking on a shortcut icon on the desktop. The CLI can not be launched from the GUI, only from the desktop icon.

Both the GUI and the CLI use a program known as the handler. Only one handler can be running at one time Due to architectural limitations, the GUI must be started before the CLI if you want the GUI and CLI to use the same handler. When the CLI is launched after the GUI, the CLI automatically finds and uses an in–progress login session with a BTS initiated under the GUI. This allows the use of the GUI and the CLI in the same BTS login session. If a CLI handler is already running when the GUI is launched (this happens if the CLI window is already running when the user starts the GUI, or if another copy of the GUI is already running when the user starts the GUI), a dialog window displays the following warning message:

The CLI handler is already running. This may cause conflicts with the LMF. Are you sure that you want to start the application?

This window also contains yes and no buttons. Selecting yes starts the

application. Selecting no terminates the application.

CLI Format Conventions

The CLI command can be broken down in the following way:

 verb  device including device identifier parameters  switch  option parameters consisting of:

– keywords – equals signs (=) between the keywords and the parameter values – parameter values

Spaces are required between the verb, device, switch, and option parameters. A hyphen is required between the device and its identifiers. Following is an example of a CLI command.

measure bbx–<bts_id>–<bbx_id> rssi channel=6 sector=5 Refer to LMF CLI Commands, R15.x 68P09251A59 for a complete

explanation of the CLI commands and their use.

Logging into a BTS

IMPORTANT

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.

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

Before attempting to log into the BTS, confirm the CDMA LMF is properly connected to the BTS (see Figure 3-2).

Prerequisites

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

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

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).

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 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.

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).

3-26

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

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 (MCC24E, MCC8E or MCC–1X)

 Broadband Transceiver (BBX)  Test Subscriber Interface Card (TSIC) – if RFDS is installed

IMPORTANT

Follow the procedure in Table 3-12 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.

WARNING

R9 RAM code must NOT be downloaded to a device that has R8 ROM code and R8 RAM code must NOT be downloaded to a device that has R9 ROM code. All devices in a BTS must have the same R–level ROM and RAM code before the optimization and ATP procedures can be performed. If a newly installed R8 BTS is to be upgraded to R9, the optimization and ATPs should be

accomplished with the R8 code. Then the site should be upgraded to R9 by the CBSC. The optimization and ATP procedures do not have to be performed again after the R9 upgrade. If a replacement R8 device needs to be used in a R9 BTS, the device ROM code can be changed with use of the LMF before the optimization and ATPs are performed for the BTS. Refer to the Download ROM Code section. A R9 device can not be converted back to a R8 device in the field without Motorola assistance.

Enable CSMs

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 CSM2 card is required when using the R–GPS. The GPS receiver (mounted on CSM–1) is the primary timing reference and synchronizes the entire cellular system. CSM–2 provides redundancy but does not have a GPS receiver.

The BTS may be equipped with a remote GPS, LORAN–C LFR, or HSO 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.

IMPORTANT

– CSMs are code loaded at the factory. This data is

retained in EEPROM. The download code procedure is required in the event it becomes necessary to code load CSMs with updated software versions. Use the status function to determine the current code load versions.

– For non–RGPS sites only, verify the CSM configured

with the GPS receiver “daughter board” is installed in the CSM–1 slot before continuing.

– The CSM(s) and MCC(s) to be enabled must have

been downloaded with code (Yellow, OOS–RAM) and data.

Table 3-15: Enable CSMs

 Step Action

1 Verify the CSM(s) have been downloaded with code (Yellow, OOS–RAM) and data. 2

Click on the target CSM. From the Device pull down, select Enable.

NOTE

If equipped with two CSMs, enable CSM–2 first and then CSM–1. A status report confirms change in the device(s) status. Click OK to close the status window.

NOTE

FAIL may be shown in the status table for enable action. If Waiting For Phase Lock is shown in the Description field, the CSM changes to the enabled state after phase lock is achieved. CSM–1 houses the GPS receiver. The enable sequence can take up to one hour to complete.

* IMPORTANT

The GPS satellite system satellites are not in a geosynchronous orbit and are maintained and operated by the United States Department of Defense (D.O.D.). The D.O.D. periodically alters satellite orbits; therefore, satellite trajectories are subject to change. A GPS receiver that is INS contains an “almanac” that is updated periodically to take these changes into account.

If an installed GPS receiver has not been updated for a number of weeks, it may take up to one hour for the GPS receiver “almanac” to be updated.

Once updated, the GPS receiver must track at least four satellites and obtain (hold) a 3-D position fix for a minimum of 45 seconds before the CSM will come in-service. (In some cases, the GPS receiver needs to track only one satellite, depending on accuracy mode set during the data load.)

Mar 2001

NOTE

If equipped with two CSMs, the LMF should display CSM-1 as bright GREEN (INS–ACT) and CSM–2 as dark green (INS–STB). After the CSMs have been successfully enabled, the PWR/ALM LEDs are steady green (alternating green/red indicates the card is in an alarm state).

If more than an hour has passed, refer to Table 3-19 and Table 3-20 to determine the cause.

CSM System Time/GPS and LFR/HSO Verification

CSM & LFR Background

The primary function of the Clock Synchronization Manager (CSM) boards (slots 1 and 2) is to maintain CDMA system time. The CSM in slot 1 is the primary timing source while slot 2 provides redundancy. The CSM2 card (CSM second generation) is required when using the remote GPS receiver (R–GPS). R–GPS uses a GPS receiver in the antenna head that has a digital output to the CSM2 card. CSM2 can have a daughter card as a local GPS receiver to support an RF–GPS signal.

The CSM2 switches between the primary and redundant units (slots 1 and 2) upon failure or command. CDMA Clock Distribution Cards (CCDs) buffer and distribute even–second reference and 19.6608 MHz clocks. CCD–1 is married to CSM–1 and CCD–2 is married to CSM 2. A failure on CSM–1 or CCD–1 cause the system to switch to redundant CSM–2 and CCD–2.

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 CSM2 card is required when using the R–GPS. DPLL circuits employed by the CSM provide switching between the primary and redundant unit upon request. Synchronization between the primary and redundant CSM cards, as well as the LFR or HSO back–up source, provides excellent reliability and performance.

Each CSM board features an ovenized, crystal oscillator that provides

19.6608 MHz clock, even second tick reference, and 3 MHz sinewave reference, referenced to the selected synchronization source (GPS, LORAN–C Frequency Receiver (LFR), or High Stability Oscillator (HSO), T1 Span, or external reference oscillator sources). The 3 MHz signals are also routed to the RDM EXP 1A & 1B connectors on the top interconnect panel for distribution to co–located frames at the site.

Fault management has the capability of switching between the GPS synchronization source and the LFR/HSO backup source in the event of a GPS receiver failure on CSM–1. During normal operation, the CSM–1 board selects GPS as the primary source (see Table 3-19). The source selection can also be overridden via the LMF or by the system software.

All boards are mounted in the C–CCP shelf at the top of the BTS frame. Figure 3-9 on page 3-36 illustrates the location of the boards in the BTS frame. The diagram also shows the CSM front panel.

CSM System Time/GPS and LFR/HSO Verification – continued

Low Frequency Receiver/ High Stability Oscillator

The CSM handles the overall configuration and status monitoring functions of the LFR/HSO. In the event of GPS failure, the LFR/HSO is capable of maintaining synchronization initially established by the GPS reference signal.

The LFR requires an active external antenna to receive LORAN RF

signals. Timing pulses are derived from this signal, which is synchronized to Universal Time Coordinates (UTC) and GPS time. The LFR can maintain system time indefinitely after initial GPS lock.

The HSO is a high stability 10 MHz oscillator with the necessary interface to the CSMs. The HSO is typically installed in those geographical areas not covered by the LORAN–C system. Since the HSO is a free–standing oscillator, system time can only be maintained for 24 hours after 24 hours of GPS lock.

Upgrades and Expansions: LFR2/HSO2/HSOX

Front Panel LEDs

LFR2/HSO2 (second generation cards) both export a timing signal to the expansion or logical BTS frames. The associated expansion or logical frames require an HSO–expansion (HSOX) whether the starter frame has an LFR2 or an HSO2. The HSOX accepts input from the starter frame and interfaces with the CSM cards in the expansion frame. LFR and LFR2 use the same source code in source selection (see Table 3-18). HSO, HSO2, and HSOX use the same source code in source selection (see Table 3-18).

NOTE

Allow the base site and test equipment to warm up for 60 minutes after any interruption in oscillator power. CSM

board warm-up allows the oscillator oven temperature and oscillator frequency to stabilize prior to test. Test equipment warm-up allows the Rubidium standard timebase to stabilize in frequency before any measurements are made.

The status of the LEDs on the CSM boards are as follows:

 Steady Green – Master CSM locked to GPS or LFR (INS).

 Rapidly Flashing Green – Standby CSM locked to GPS or LFR

(STBY).

 Flashing Green/Rapidly Flashing Red – CSM OOS–RAM attempting

If there is a communications problem between the LMF and any piece of test equipment, verify that the GPIB addresses have been set correctly (normally 13 for a power meter and 18 for a CDMA

analyzer). The following equipment is required to perform optimization:

 LMF  Test set  Directional coupler and attenuator  RF cables and connectors

Refer to Table 3-22 for an overview of connections for test equipment currently supported by the LMF. In addition, see the following figures:

Supported Test Sets

 Figure 3-11 and Figure 3-12 show the test set connections for TX

calibration.

 Figure 3-13 and Figure 3-14 show the test set connections for

optimization/ATP tests.

 Figure 3-15 and Figure 3-16 show typical TX and RX ATP setup with

a directional coupler (shown with and without RFDS).

Optimization and ATP testing may be performed using one of the following test sets:

 CyberTest  Advantest R3465 and HP 437B or Gigatronics Power Meter  Hewlett–Packard HP 8935  Hewlett–Packard HP 8921 (W/CDMA and PCS Interface for

Equipment Warm-up

IMPORTANT

Warm-up BTS equipment for a minimum of 60 minutes prior to performing the BTS optimization procedure. This assures BTS site stability and contributes to optimization accuracy. (Time spent running initial power-up, hardware/firmware audit, and BTS download counts as warm-up time.)

Calibrating Cables

Figure 3-10 shows the cable calibration setup for various supported test sets. The left side of the diagram depicts the location of the input and output ports of each test set, and the right side details the set up for each test.

WARNING

Before installing any test equipment directly to any BTS TX OUT connector, verify there are NO CDMA BBX channels keyed. At active sites, have the OMC-R/CBSC place the antenna (sector) assigned to the LPA under test OOS. Failure to do so can result in serious personal injury and/or equipment damage.

Test Set Calibration

Test Set Calibration Background

Proper test equipment calibration ensures that the test equipment and associated test cables do not introduce measurement errors, and that measurements are correct.

NOTE

This procedure must be performed prior to beginning the optimization. Verify all test equipment (including all associated test cables and adapters actually used to interface all test equipment and the BTS) has been calibrated and maintained as a set.

If the test set being used to interface with the BTS has been calibrated and maintained as a set, this procedure does not need to be performed. (Test Set includes LMF terminal, communications test set, additional test equipment, associated test cables, and adapters.)

Purpose of Test Set Calibration

CAUTION

If any piece of test equipment, test cable, or RF adapter, that makes up the calibrated test equipment set, has been replaced, re-calibration must be performed. Failure to do so can introduce measurement errors, resulting in incorrect measurements and degradation to system performance.

IMPORTANT

These procedures access the LMF automated calibration routine used to determine the path losses of the supported communications analyzer, power meter, associated test cables, and (if used) antenna switch that make up the overall calibrated test set. After calibration, the gain/loss offset values are stored in a test measurement offset file on the LMF.

Calibration of the communications test set (or equivalent test equipment) must be performed at the site before calibrating the overall test set. Calibrate the test equipment

after it has been allowed to warm–up and stabilize for a minimum of 60 minutes.

Selecting Test Equipment

Manually Selecting Test Equipment in a Serial Connection Tab

Use LMF Options from the Options menu list to select test equipment automatically (using the autodetect feature) or manually.

A Serial Connection and a Network Connection tab are provided for test equipment selection. The Serial Connection tab is used when the test equipment items are connected directly to the LMF computer via a GPIB box (normal setup). The Network Connection tab is used when the test equipment is to be connected remotely via a network connection.

Prerequisites

Ensure the following prerequisites have been met before proceeding:

 Test equipment is correctly connected and turned on.  CDMA LMF computer serial port and test equipment are connected to

the GPIB box.

Test equipment can be manually specified before, or after, the test equipment is connected. The LMF does not check to see if the test equipment is actually detected for manual specification. Follow the procedure in Table 3-23 to select test equipment manually.

Calibrating Test Equipment

Table 3-25: Test Equipment Calibration

The calibrate test equipment function zeros the power measurement level of the test equipment item that is to be used for TX calibration and audit. If both a power meter and an analyzer are connected, only the power meter is zeroed.

Use the Calibrate Test Equipment menu item from the Util menu to calibrate test equipment. The test equipment must be selected before calibration can begin. Follow the procedure in Table 3-25 to calibrate the test equipment.

Prerequisites

Ensure the following prerequisites have been met before proceeding:

 Test equipment to be calibrated has been connected correctly for tests

that are to be run.

 Test equipment has been selected.

 Step Action

1 From the Util menu, select Calibrate Test Equipment.

A Directions window is displayed. 2 Follow the directions provided. 3 Click on Continue to close the Directions window.

A status report window is displayed. 4 Click on OK to close the status report window.

Calibrating Cables

The cable calibration function measures the loss (in dB) for the TX and RX cables that are to be used for testing. A CDMA analyzer is used to measure the loss of each cable configuration (TX cable configuration and RX cable configuration). The cable calibration consists of the following:

 Measuring the loss of a short cable – This is required to compensate

for any measurement error of the analyzer. The short cable (used only for the calibration process) is used in series with both the TX and RX cable configuration when measuring. The measured loss of the short cable is deducted from the measured loss of the TX and RX cable configuration to determine the actual loss of the TX and RX cable configurations. The result is then adjusted out of both the TX and RX measurements to compensate for the measured loss.

Mar 2001

 The short cable plus the RX cable configuration loss is measured –

The RX cable configuration normally consists only of a coax cable with type-N connectors that is long enough to reach from the BTS RX port of the test equipment.

Calibrating Cables with a CDMA Analyzer

 The short cable plus the TX cable configuration loss is measured –

The TX cable configuration normally consists of two coax cables with type-N connectors and a directional coupler, a load, and an additional attenuator (if required by the specified BTS). The total loss of the path loss of the TX cable configuration must be as required for the BTS (normally 30 or 50 dB).

Cable Calibration is used to calibrate both TX and RX test cables. Follow the procedure in Table 3-26 to calibrate the cables. Figure 3-10 illustrates the cable calibration test equipment setup. Appendix F covers the procedures for manual cable calibration.

NOTE

LMF cable calibration for PCS systems (1.7/1.9 GHz) cannot be accomplished using an HP8921 analyzer with PCS interface or an Advantest analyzer. A different analyzer type or the signal generator and spectrum analyzer method must be used (refer to Table 3-27 and Figure 3-17). Cable calibration values are then manually entered.

Prerequisites

Ensure the following prerequisites have been met before proceeding:

 Test equipment to be calibrated has been connected correctly for cable

calibration.

 Test equipment has been selected and calibrated.

Table 3-26: Cable Calibration

 Step Action

1 From the Util menu, select Cable Calibration.

Bay Level Offset Calibration

Introduction to Bay Level Offset Calibration

Calibration compensates for normal equipment variations within the BTS and assures maximum measurement accuracy.

RF Path Bay Level Offset Calibration

Calibration identifies the accumulated gain in every transmit path (BBX slot) at the BTS site and stores that value in a BLO database calibration table in the LMF. The BLOs are subsequently downloaded to each BBX.

For starter frames, each receive path starts at a BTS RX antenna port and terminates at a backplane BBX slot. Each transmit path starts at a BBX backplane slot, travels through the LPA, and terminates at a BTS TX antenna port.

For expansion frames each receive path starts at the BTS RX port of the cell site starter frame, travels through the frame-to-frame expansion cable, and terminates at a backplane BBX slot of the expansion frame. The transmit path starts at a BBX backplane slot of the expansion frame, travels though the LPA, and terminates at a BTS TX antenna port of the same expansion frame.

When to Calibrate BLOs

Calibration identifies the accumulated gain in every transmit path (BBX slot) at the BTS site and stores that value in a BLO database. Each transmit path starts at a C–CCP shelf backplane BBX slot, travels through the LPA, and ends at a BTS TX antenna port. When the TX path calibration is performed, the RX path BLO is automatically set to the default value.

At omni sites, BBX slots 1 and 13 (redundant) are tested. At sector sites, BBX slots 1 through 12, and 13 (redundant) are tested. Only those slots (sectors) actually equipped in the current CDF are tested, regardless of physical BBX board installation in the slot.

Calibration of BLOs is required:

 After initial BTS installation  Once each year  After replacing any of the following components or associated

interconnecting RF cabling:

– BBX board – C–CCP shelf – CIO card – CIO to LPA backplane RF cable – LPA backplane – LPA

TX Path Calibration

The TX Path Calibration assures correct site installation, cabling, and the first order functionality of all installed equipment. The proper function of each RF path is verified during calibration. The external test equipment is used to validate/calibrate the TX paths of the BTS.

Before installing any test equipment directly to any TX OUT connector you must first verify that there are no

CDMA channels keyed. Have the OMC–R place the sector assigned to the LPA under test OOS. Failure to do so can result in serious personal injury and/or equipment damage.

WARNING

CAUTION

Always wear a conductive, high impedance wrist strap while handling any circuit card/module. If this is not done, there is a high probability that the card/module could be damaged by ESD.

IMPORTANT

At new site installations, to facilitate the complete test of each CCP shelf (if the shelf is not already fully populated with BBX boards), move BBX boards from shelves currently not under test and install them into the empty BBX slots of the shelf currently being tested to insure that all BBX TX paths are tested.

– This procedure can be bypassed on operational sites

that are due for periodic optimization.

– Prior to testing, view the CDF file to verify the

correct BBX slots are equipped. Edit the file as required to include BBX slots not currently equipped (per Systems Engineering documentation).

BLO Calibration Data File

During the calibration process, the LMF creates a bts–n.cal calibration (BLO) offset data file in the bts–n folder. After calibration has been completed, this offset data must be downloaded to the BBXs using the Download BLO function. An explanation of the file is shown below.

NOTE

The CAL file is subdivided into sections organized on a per slot basis (a slot Block).

Slot 1 contains the calibration data for the 12 BBX slots. Slot 20 contains the calibration data for the redundant BBX. Each BBX slot header block contains:

Due to the size of the file, Motorola recommends that you print out a hard copy of a bts.cal file and refer to it for the following descriptions.

 A creation Date and Time – broken down into separate parameters of

createMonth, createDay, createYear, createHour, and createMin.

 The number of calibration entries – fixed at 720 entries corresponding

to 360 calibration points of the CAL file including the slot header and actual calibration data.

 The calibration data for a BBX is organized as a large flat array. The

array is organized by branch, sector, and calibration point. – The first breakdown of the array indicates which branch the

contained calibration points are for. The array covers transmit, main receive and diversity receive offsets as follows:

TX Path Calibration

The assigned channel frequency and power level (as measured at the top of the frame) for transmit calibration are derived from the site CDF files. For each BBX, the channel frequency is specified in the CDF file parameter and the power is specified in the SIFPilotPwr CDF file parameter for the sector associated with the BBX (located under the parameter).

ChannelList

NOTE

If both the BTS–x.cdf and CBSC–x.cdf files are current, all information will be correct on the LMF. If not, the carrier and channel will have to be set for each test.

The calibration procedure attempts to adjust the power to within + of the desired power. The calibration will pass if the error is less than

1.5 dB.

+ The TX Bay Level Offset at sites WITHOUT the directional coupler

option, is approximately 42.0 dB ±3.0 dB.

0.5 dB

 At sites WITHOUT RFDS option, BLO is approximately

42.0 dB ±4.0 dB. A typical example would be TX output power measured at BTS (36.0 dBm) minus the BBX TX output level (approximately –6.0 dBm) would equate to 42 dB BLO.

The TX Bay Level Offset at sites WITH the directional coupler option, is approximately 41.4 dB ±3.0 dB. TX BLO = Frame Power Output minus BBX output level.

 Example: TX output power measured at RFDS TX coupler

(39.4 dBm) minus the BBX TX output level (approximately

–2.0 dBm) and RFDS directional coupler/cable (approximately –0.6 dBm) would equate to 41.4 dB BLO.
