Introduction

Required Tools

Cabling Inspection

The following information is used to check for any electrical short circuits and to verify the operation and tolerances of the cellsite and BTS power supply units before applying power for the first time. It contains instructional information on the initial proper power up procedures for the SC 4812ET power cabinet and RF cabinet. Also presented are tests to be preformed on the power cabinet. Please pay attention to all cautions and warning statements in order to prevent accidental injury to personnel.

The following tools are used in the procedures.

 DC current clamp (600 Amp capability with jaw size to accommodate

2/0 cable).

 Hot Air Gun – (optional for part of the Alarm Verification)  Digital Multimeter (DMM)

Using the site-specific documentation generated by Motorola Systems Engineering, verify that the following cable systems are properly connected:

 Receive RF cabling – up to 12 RX cables  Transmit RF cabling – up to six TX cables

IMPORTANT

For positive power applications (+27 V):

 The positive power cable is red.  The negative power cable is black. (The black power

cable is at ground potential.)

Initial Inspection and Setup

CAUTION

Ensure all battery breakers for unused battery positions are open (pulled out) during any part of the power up process, and remain in the off position when leaving the site.

Table 2-2: Initial Inspection and Setup

Step Action

1 Verify that ALL AC and DC breakers are turned OFF in both the Power and RF cabinets. Verify that

the DC power cables between the Power and RF cabinets are connected with the correct polarity

2 The RED cables connect to the uppermost three (3) terminals (marked +) in both cabinets. Confirm

that the split phase 240/120 AC supply is correctly connected to the AC load center input.

Power Up Sequence

The first task in the power up sequence is to apply AC power to the Power cabinet. Once power is applied a series of AC Voltage measurements is required.

Table 2-3: AC Voltage Measurements

Step Action

1 Measure the AC voltages connected to the AC load center (access the terminals from the rear of the

cabinet after removing the AC load center rear panel). See Figure 2-2.

2 Measure the AC voltage from terminal L1 to neutral. This voltage should be in the range of nominally

115 to 120 V AC.

surge protection module inside the AC load center.

3 Measure the AC voltage from terminal L1 to ground. This voltage should be in the range of nominally

115 to 120 V AC.

4 Measure the AC voltage from terminal L2 to neutral. This voltage should be in the range of nominally

115 to 120 V AC.

5 Measure the AC voltage from terminal L2 to ground. This voltage should be in the range of nominally

115 to 120 V AC.

6 Measure L1 – L2 – should be from 208 to 240 V AC.

CAUTION

If the AC voltages are in excess of 120 V (or exceed 200 V) when measuring between terminals L1 or L2 to neutral or ground, STOP and Do Not proceed until the cause of the higher voltages are determined. The power cabinet WILL be damaged if the Main breaker is turned on with excessive voltage on the inputs.

FW00305

Once AC Voltage Measurements are complete, apply AC power to the Power Cabinet. Table 2-4 provides the procedure for applying AC power.

Table 2-4: Applying AC Power

Step Action

1 When the 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 AC Load Center are illuminated (see Figure 2-7).

2 Turn Rectifier 1 and Rectifier 2 AC branch breakers (on the AC Load Center) ON. All the installed

rectifier modules (see Figure 2-7) will start up and should each have two green LEDs (DC and Power) illuminated.

3 Turn the Meter Alarm Panel module, ON (see Figure 2-3), while observing the K2 contact in the

PDA assembly (see Figure 2-9). The contact should close. The Meter Alarm Panel voltage meter should read approximately 27.4 +

0.2 Vdc.

4 Turn the Temperature Compensation Panel (TCP) ON, (see Figure 2-4). 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.

Table 2-5: Power Cabinet Power Up Tests

Step Action

1 Probe the output voltage test point on the Meter Alarm Panel while pressing the 25° C set button on

the TCP (see Figure 2-4). 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.

2 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. 3 Ensure the RF cabinet 400 Amp main DC breaker is OFF. 4 Close the three (3) Main DC breakers on the Power Cabinet ONLY. Close by holding in the reset

button on the front of the PDA, and engaging one breaker at a time. 5 Measure the voltage between the + and – terminals at the rear of the Power Cabinet and the RF

Cabinet, observing that the polarity is correct. The voltage should be the same as the measurement in

step 2. 6 Place the probes across the black and red battery buss bars in each battery compartment. Place the

probe at the bottom of the buss bars where the cables are connected. The DC voltage should measure

the same as the previous step.

DC Power Pre-test (BTS Frame)

Before applying any power to the BTS cabinet, verify there are no shorts in the RF or power DC distribution system (see Figure 2-5).

Table 2-6: DC Power Pre–test (BTS Frame)

Step Action

1 Physically verify that all AC rectifiers supplying power to the RF cabinets are OFF or disabled (see

Figure 2-5). There should be no 27 Vdc on DC feed terminals.

2 On each RF cabinet:

 Unseat all circuit boards/ modules in the distribution shelf, transceiver shelf, and Single Carrier

Linear Power Amplifier (SCLPA) shelves, but leave them in their associated slots.

 Unseat all circuit boards (except CCD and CIO cards) in the C–CCP shelf and LPA shelves, but

leave them in their associated slots.

 Set C–CCP shelf breakers to the OFF position by pulling out power distribution breakers (labeled

C–CCP 1, 2, 3 – located on the power distribution panel).

 Set LPA breakers to the OFF position by pulling out power distribution breakers (8 breakers,

Battery Charge Test (Connected Batteries)

Table 2-8: Battery Charge Test (Connected Batteries)

Step Action

1 Close the battery compartment breakers for connected batteries ONLY. This process should be

completed quickly to avoid individual battery strings with excess charge current

Table 2-8 lists the step–by–step instructions for testing the batteries.

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

bars in each battery cabinet. 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. 3 The current in each string should be approximately equal (+ 5 A). 4 The bargraph meters on the rectifier modules can be used as a rough estimate of the total battery

charge current. Each rectifier module has eight (8) LEDs to represent the output current. Each

illuminated LED indicates that approximately 12.5% (1/8 or 8.75 A) of the rectifiers maximum (70 A)

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 A, therefore, 3 X 8.75 equals

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

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. 5 Allow a few minutes to ensure that the battery charge current stabilizes before taking any further

action. Recheck the battery current in each string. If the batteries had a reasonable charge, the current

in each string should reduce to less than 5 A. 6 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.

Battery Discharge Test

Perform the test procedure in Table 2-9 only when the battery current is less than 5 A per string. Refer to Table 2-8 on the procedures for checking current levels.

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.

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

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

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

Apr 2001

 Download the RFDS TSIC (if installed).  Verify the operation of the GPS and HSO signals.  Enable the following devices (in the order listed):

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

 Connect the required test equipment for a full optimization.  Select the test equipment.  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.

DRAFT

Optimization/Calibration – Introduction – continued

 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.

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

paths.

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

failure and repeat the full optimization for the failed path.

Cell–site Types

Cell–site Data File

 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:

 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 – 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.

 CSM equipage including redundancy  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, 68P64114A78, for additional information on the layout of the LMF directory structure (including CDF file locations and formats).

Optimization/Calibration – 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, 68P64114A78, 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.

Isolate Span Lines/Connect LMF

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 CDMA BTS. This prevents the CBSC from inadvertently sending control information to the CDMA 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).

– 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.

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.

Each 19 inch rack can support two CSU M–PATH 537 modules. Each M–PATH 537 module supports one and only one 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.

Setting the Control Port

Whichever control port is chosen, it must first be set up so the control port switches match the communication parameters being used by the control device. If using the rear–panel DTE control port, set the shelf–address switch SA5 to “up” (leave the switch down for the rear–panel DCE control port).

For more information, refer to the Kentrox Installation Guide, manual number 65–77538001 which is provided with each CSU.

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.

CDMA LMF Home Directory

The CDMA LMF installation program creates the default home directory c:\wlmf, and installs the application files and subdirectories (folders) in it. Because this can be changed at installation, the CDMA LMF home directory will be referred to with the generic convention of:

Where: <x> = the LMF computer drive letter where the CDMA LMF home

directory is located. <lmf home directory> = the directory path or name where the CDMA

LMF is installed

Copy CBSC CDF Files to the LMF Computer

Before logging on to a BTS with the LMF 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 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 LMF computer.

IMPORTANT

The procedure in Table 3-4 lists the steps required to transfer the CDF files from the CBSC to the LMF computer. For any further information, refer to the CDMA LMF Operator’s Guide (Motorola part number 68P64114A21) or the LMF Help screen..

Table 3-4: Copying CBSC CDF Files to the LMF

Step Action

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 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.

1 Login to the CBSC workstation. 2 Insert a DOS–formatted floppy diskette in the workstation drive. 3 Type eject –q and press <Enter>. 4 Type mount and press <Enter>.

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, where the files to be copied reside, by typing cd <directoryname>

(e.g., cd bts–248) and pressing <Enter>.

6 Type ls and press the Enter key to display the list of files in the directory.

Table 3-4: Copying CBSC CDF Files to the LMF

Step Action

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 <Enter>.

10 Remove the diskette from the CBSC drive. 11 If it is not running, start the Windows operating system on the LMF computer. 12 Insert the diskette containing the bts–#.cdf and cbsc–#.cdf files into the LMF computer. 13 Using Windows Explorer (or equivalent program), create a corresponding bts–# folder in the <lmf

home directory> 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 <lmf home directory>\wlmf\cdma\bts–# folders created in step 13.

Creating a Named HyperTerminal Connection for MMI Connection

Apr 2001

SC4812ET BTS Optimization/ATP — CDMA LMF

Confirming or changing the configuration data of certain BTS 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.

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.

Pinging the Processors

For proper operation, the integrity of the Ethernet LAN A and B links must be be verified. Figure 3-5 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 3-7 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.

Using CDMA LMF

Basic LMF Operation

NOTE

The terms “CDMA LMF” and “WinLMF” are interchangeable

Basic LMF Command Line Interface (CLI) 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.

Apr 2001

. Both the GUI and the CLI use a program known as the handler. Only one

handler can be running at one time. The architectural design is such that 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:

Logging into a BTS

– keywords – equals sign (=) between the keyword and the parameter value – 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 the LMF CLI Commands, R 15.X (68P09251A59) for a

complete explanation of the CLI commands and their use.

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 wrong results. Failure to

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

3-22

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.

Before attempting to log into the BTS, confirm the CDMA LMF is properly connected to the BTS (see Figure 3-4). Follow the procedure in Table 3-8 to log into a BTS.

Prerequisites

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

 The LMF 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

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 3-6 and Figure 3-4).

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 used as 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 LORAN–C LFR, 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.

IMPORTANT

Follow the steps outlined in Table 3-16 to enable the CSMs installed in the C–CCP shelves.

Table 3-16: Enable CSMs

Step Action

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

For RF–GPS, verify the CSM configured with the GPS receiver “daughter board” is installed in the frame’s CSM 1 slot before continuing.

NOTE

If equipped with two CSMs, enable CSM–2 first A status report is displayed confirming change in the device(s) status. Click OK to close the status report 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 (see below).

3-30

* 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 a GPS receiver has not been updated for a number of weeks, it may take up to an 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).

CSM System Time – GPS & LFR/HSO Verification

Clock Synchronization Manager System Time

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.

Each CSM2 board features an ovenized, crystal oscillator that provides

19.6608 MHz clock, even second pulse, and 3 MHz referenced to the selected synchronization source (see Table 3-19):

Low Frequency Receiver/ High Stability Oscillator

 GPS: local/RF–GPS or remote/R–GPS  LORAN–C Frequency Receiver (LFR) or High Stability Oscillator

(HSO)

 External reference oscillator sources

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.

Synchronization between the primary and redundant CSM CCD pairs, as well as the LFR or HSO back–up to GPS synchronization, increases reliability.

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 indefinately after initial GPS lock.

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

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

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 3-19). HSO, HSO2, and HSOX use the same source code in source selection (see Table 3-19).

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.

Test Equipment Set–up

Connecting Test Equipment to the BTS

All test equipment is controlled by the LMF via IEEE–488/GPIB bus. The LMF requires each piece of test equipment to have a factory set GPIB address. 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 test equipment is required to perform optimization,

calibration and ATP tests:

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

Refer to Table 3-21 for an overview of connections for test equipment currently supported by LMF. In addition, see the following figures:

Supported Test Sets

 Figure 3-9 and Figure 3-10 show the test set connections for TX

calibration

 Figure 3-11 and Figure 3-12 show the test set connections 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.)

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

Background

Proper test equipment setup 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.)

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

Purpose

3-50

These procedures access the CDMA 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 CDMA LMF.

SC4812ET BTS Optimization/ATP — CDMA 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

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

Prerequisites

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 CDMA 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.

Ensure the following has been completed before selecting test equipment:

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

the GPIB box.

Manually Selecting Test Equipment in a Serial Connection Tab

Test equipment can be manually specified before, or after, the test equipment is connected. CDMA LMF does not check to see if the test equipment is actually detected for manual specification.

Table 3-22: Selecting Test Equipment Manually in a Serial Connection Tab

Step Action

1 From the Options menu, select LMF Options. The LMF Options window appears. 2 Click on the Serial Connection tab (if not in the forefront). 3 Select the correct serial port in the COMM Port pick list (normally COM1). 4 Click on the Manual Specification button (if not enabled). 5 Click on the check box corresponding to the test item(s) to be used. 6 Type the GPIB address in the corresponding GPIB address box. Recommended Addresses

13=Power Meter 18=CDMA Analyzer

7 Click on Apply. (The button will darken until the selection has been committed.)

NOTE

With manual selection, CDMA LMF does not detect the test equipment to see if it is connected and communicating with CDMA LMF.

Automatically Selecting Test Equipment in a Serial Connection Tab

When using the auto-detection feature to select test equipment, the CDMA LMF examines which test equipment items are actually communicating with CDMA LMF. Follow the procedure in Table 3-23 to use the auto-detect feature.

Table 3-23: Selecting Test Equipment Using Auto-Detect

Step Action

1 From the Options menu, select LMF Options. The LMF Options window appears. 2 Click on the Serial Connection tab (if not in the forefront). 3 Select the correct serial port in the COMM Port pick list (normally COM1). 4 Click on Auto–Detection (if not enabled). 5 Type in the GPIB addresses in the box labeled GPIB address to search (if not already displayed).

NOTE

When both a power meter and analyzer are selected, the first item listed in the GPIB addresses to search box will be used for RF power measurements (i.e., TX calibration). The address for a power meter is normally 13 and the address for a CDMA analyzer is normally 18. If 13,18 is included in the GPIB addresses to search box, the power meter (13) will be used for RF power measurements. If the

test equipment items are manually selected the CDMA analyzer is used only if a power meter is not selected.

6 Click Apply. The button will darken until the selection has been committed. A check mark will

appear in the Manual Configuration section for detected test equipment items.

Calibrating Test Equipment

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.

Calibrate Test Equipment from the Util menu list is used to calibrate test equipment item before being used for testing. The test equipment must be selected before beginning calibration. Follow the procedure in Table 3-24 to calibrate the test equipment.

Table 3-24: Test Equipment Calibration

Step Action

1 From the Util menu, select Calibrate Test Equipment. A Directions window is displayed. Follow

the instructions provided.

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

4 Click on OK to close the status report window.

Calibrating Cables

The cable calibration function is used to measure 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 steps.

 Measure the loss of a short cable. This is done to compensate for any

measurement error of the analyzer. The short cable, which is used only for the calibration process, is used in series with both the TX and RX cable configuration when they are measured. 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. This deduction is done so any error in the analyzer measurement will be adjusted out of both the TX and RX measurements.

 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 the test equipment.

Apr 2001

 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 BTS type. The total loss of the path loss of the TX cable configuration must be as required for the BTS (normally 30 or 50 dB). The Motorola Cybertest analyzer is different in that the required attenuation/load is built into the test set so the TX cable configuration consists only of the required length coax cable.

Bay Level Offset Calibration

Introduction

RF Path Bay Level Offset Calibration

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

When to Calibrate BLOs

Calibration identifies the accumulated gain in every transmit path (BBX2 slot) at the BTS site and stores that value in the CAL file. The BLOs are subsequently downloaded to each BBX2.

Each receive path starts at a BTS RX antenna port and terminates at a backplane BBX2 slot. Each transmit path starts at a BBX2 backplane slot, travels through the LPA, and terminates at a BTS TX antenna port.

Calibration identifies the accumulated gain in every transmit path (BBX2 slot) at the BTS site and stores that value in the CAL file. Each transmit path starts at a C–CCP shelf backplane BBX2 slot, travels through the LPA, and ends at a BTS TX antenna port. When the TX path calibration is performed, the RX path BLO will automatically be set to the default value.

Calibration of BLOs is required after initial BTS installation. The BLO data of an operational BTS site must be re-calibrated once

each year. Motorola recommends re-calibrating the BLO data for all associated RF paths after replacing any of the following components or associated interconnecting RF cabling:

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.

WARNING

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.

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 BBX2 boards), move BBX2 boards from shelves currently not under test and install them into the empty BBX2 slots of the shelf currently being tested to insure that all BBX2 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 BBX2 slots are equipped. Edit the file as required to include BBX2 slots not currently equipped (per Systems Engineering documentation).

BLO Calibration Data File

During the calibration process, the LMF creates a calibration (BLO) data file. After calibration has been completed, this offset data must be downloaded to the BBX2s using the Download BLO function. An explanation of the file is shown below.

NOTE

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.

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 BBX2 slots. Slot 20 contains the calibration data for the redundant BBX2 (see Table 3-31). Each BBX2 slot header block contains:

 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 BBX2 is organized as a large flat array. The

array is organized by branch, BBX2 slot, 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:

Transmit (TX) Path Calibration

The assigned channel frequency and power level (as measured at the top of the frame) for transmit calibration is derived from the site CDF file. For each BBX2, 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 BBX2 (located under the parameter).

ParentSECTOR field of the ParentCARRIER CDF file

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.

 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 BBX2 TX output level (approximately –6.0 dBm) would equate to 42 dB BLO.

ChannelList

0.5 dB

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 BBX2 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.

The LMF Tests menu list items, TX Calibration and All Cal/Audit, perform the TX BLO Calibration test for a XCVR(s). The All Cal/Audit menu item performs TX calibration, downloads BLO, and performs TX audit if the TX calibration passes.
