Folder Structure Overview

Figure 3-1: LMF Folder Structure

Preparing the LMF68P09255A69-3

The LMF uses a <x>:\<lmf home directory> folder that contains all of the essential data for installing and maintaining the BTS. The following list outlines the folder structure for LMF. Except for the bts-nnn folders, these folders are created as part of the LMF installation. Refer to the CDMA LMF Operator’s Guide for a complete description of the folder structure.

NOTE

(C:)

x:\<lmf home directory> folder

cdma folder

BTS-nnn folders (A separate folder is

required for each BTS where bts-nnn is the unique BTS number; for example, bts-163.)

loads folder

version folder (A separate folder is required for each different version; for example, a folder name 2.8.1.1.1.5.)

code folder

data folder

The “loads” folder and all the folders below it are not available from the LMF for Software Release 2.16.1.x. These folders may be present as as a legacy from previous software versions or downloaded from the CBSC/OMC-R.

T1/E1 Span Interface

68P09255A69-3

NOTE

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

Each frame is equipped with one 50-pair punchblock for spans, customer alarms, remote GPS, and BTS frame alarms. See Figure 3-4 and refer to Table 3-6 for the physical location and punchdown location

information. Before connecting the LMF computer to the frame LAN, the

OMC-R/CBSC must disable the BTS and place it OOS. This will allow the LMF to control the BTS, and prevent the CBSC from inadvertently sending control information to the BTS during LMF-based tests.

Isolate BTS from T1/E1 Spans

Once the OMC-R/CBSC has disabled the BTS, the spans must be disabled to ensure the LMF will maintain control of the BTS. To disable the spans, disconnect the BTS-to-CBSC Transcoder span cable connectors from the Span I/O cards (Figure 3-2).

T1/E1 Span Isolation

Table 3-5 describes the action required for span isolation.

Table 3-5: T1/E1 Span Isolation

Step Action

1 Have the OMCR/CBSC place the BTS OOS. 2 To disable the span lines, locate the connector for the span or spans which must be disabled and

remove the respective connector from the applicable SCCP cage Span I/O board (Figure 3-2).

Configure Optional Channel Service Units

The M-PATH 537 Channel Service Unit (CSU) module provides in-band SNMP-managed digital service access to T1 and fractional T1 lines. The M-PATH 437 Channel Service Unit (CSU) module provides in-band SNMP-managed digital service access to E1 and fractional E1 lines. CSU modules plug into the CSU shelf (see Figure 3-3).

The CSU shelf can support two M-PATH 537 or two M-PATH 437 CSU modules. A 537 CSU module supports a single T1 span connection. A 437 CSU module supports a single E1 span connection.

Remote M-PATH management is available through SNMP over an in-band data link on the span 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.

Programming of the M-PATH is accomplished through the DCE 9-pin connector on the front panel of the CSU shelf. Manuals and an MS Windows programming disk are supplied with each unit.

For more information refer to M-PATH T1 Channel Service Unit User’s Guide, Kentrox part number 65-77538101 or the ADC M-PATH E1 Channel Service Unit User’s Guide, Kentrox part number 1174139.

Setting the Control Port

Aug 2002

Whichever control port is chosen, it must first be configured so the control port switch settings 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.” If using the rear-panel DCE control port, position the SHELF ADDRESS switch down.

For more information, refer to the 2-Slot Universal Shelf Installation Guide, Kentrox part number 65-78070001, the M-PATH T1 Channel Service Unit Installation Guide, Kentrox part number 65-77538001, or the M-PATH E1 Channel Service Unit Installation Guide, Kentrox part number 1174662, depending on installed equipment.

Using the LMF

Basic LMF Operation

Using the LMF68P09255A69-3

LMF Coverage in This Publication - The LMF application program supports maintenance of both CDMA and SAS BTSs. All references to the LMF in this publication are to the CDMA portion of the program.

Operating Environments - The LMF application program allows the user to work in the two following operating environments which are accessed using the specified desktop icons:

 Graphical User Interface (GUI) using the WinLMF icon  Command Line Interface (CLI) using the WinLMF CDMA 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 - Basic operation of the LMF in either environment includes performing the following:

 Selecting and deselecting BTS devices  Enabling devices  Disabling devices  Resetting devices  Obtaining device status

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

 Sorting a status report window

For detailed information on performing these and other LMF operations, refer to the LMF Help function on-line documentation.

NOTE

The LMF Display and the BTS

BTS Display - When the LMF is logged into a BTS, a frame tab is displayed for each RF modem frame (RFMF). For SC4812-series BTSs, the BTS frames are considered the RFMFs. The frame tab will be labeled with “CDMA” and the BTS number, a dash, and the frame number (for example, BTS-812-1 for BTS 812, RFMF 1). If, as with a single-frame SC4812ET Lite, there is only one frame for the BTS, there will only be one tab.

CDF Requirements - For the LMF to recognize the devices installed in the BTS, a BTS CDF file which includes equipage information for all the devices in the BTS must be located in the applicable <x>:\<lmf home directory>\cdma\bts-# folder. To provide the necessary channel assignment data for BTS operation, a CBSC CDF file which includes channel data for all BTS RFMFs is also required in the folder.

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

Logging Into a BTS

68P09255A69-3

RFDS Display - If an RFDS is included in the CDF file, an RFDS tab labeled with “RFDS,” a dash and the BTS number-frame number combination (for example, RFDS-812-1 ) will be displayed.

Logging into a BTS establishes a communication link between the BTS and the LMF. An LMF session can be logged into only one BTS at a time.

Prerequisites

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

 The LMF is correctly installed on the LMF computer.  A bts-nnn folder with the correct CDF and CBSC files exists.  The LMF computer was connected to the BTS before starting the

Windows operating system and the LMF software. If necessary, restart the computer after connecting it to the BTS in accordance with Table 3-10 and Figure 3-6.

CAUTION

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.

BTS Login from the GUI Environment

Follow the procedures in Table 3-11 to log into a BTS when using the GUI environment.

Table 3-11: BTS GUI Login Procedure

 Step Action

Start the LMF GUI environment by double-clicking on the WinLMF desktop icon (if the LMF is

not running).

- An LMF window will open and display the LMF build number in the title bar.

NOTE

If a warning similar to the following is displayed, select No, shut down other LMF sessions which may be running, and start the LMF GUI environment again:

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

Yes No

Pinging the BTS

For proper operation, the integrity of the Ethernet LAN A and B links must be verified. Figure 3-8 represents a typical BTS Ethernet configuration for an SC4812ET Lite stand-alone or companion frame. The drawing depicts cabling and termination for both the A and B LANs.

Ping is a program that sends request data packets to hosts on a network,

in this case GLI modules on the BTS LAN, to obtain a response from the “target” host specified by an IP address.

Follow the steps in Table 3-16 to ping each processor (on both LAN A and LAN B) and verify LAN redundancy is working properly.

CAUTION

Always wear an approved anti-static wrist strap while handling any circuit card/module to prevent damage by Electro-Static Discharge (ESD).

NOTE

The Ethernet LAN A and B cables and/or terminations must be installed on each frame/enclosure external LAN connector before performing this test. All other processor board LAN connections are made through the backplanes.

Table 3-16: Pinging the Processors

Step Action

1 If this is a first-time communication with a newly-installed frame or a GLI card which has been

replaced, perform the procedure in Table 6-3 and then return to step 2.

2 Be sure any uncabled LAN A and B IN and OUT connectors in the power entry compartment (rear of

frame - Figure 3-4 and Figure 3-8) are terminated with 50 Ω loads.

3 If it has not already been done, connect the LMF computer to the BTS (refer to Table 3-10 and

Figure 3-6.)

4 If it has not already been done, start a GUI LMF session and log into the BTS ( refer to Table 3-11). 5 In the power entry compartment, remove the 50Ω termination on the frame LAN B IN connector.

- The LMF session should remain active.

6 Replace the 50Ω terminator on the BTS frame LAN B IN connector. 7 From the Windows desktop, click the Start button and select Run. 8 In the Open box, type ping and the MGLI IP address (for example, ping 128.0.0.2).

NOTE

128.0.0.2 is the default IP address for the GLI card in slot GLI-1 in field BTS units.

9 Click on OK.

10 If the targeted module responds, a DOS window will appear with a display similar to the following:

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

- If the device responds, proceed to step 18.

If there is no response, the following is displayed:

Request timed out

- If the GLI fails to respond, it should be reset and re-pinged. If it still fails to respond, typical problems would be: failure of the LMF to login, shorted BNC-to-inter-frame cabling, open cables, crossed A and B link cables, or the GLI itself.

11 Logout of the BTS as described in Table 3-13, exit from the LMF program, and restart the Windows

operating system on the LMF computer.

12 Restart the LMF GUI program as described in LMF Help function on-line documentation, and log into

the BTS as described in Table 3-11.

13 Perform steps 7 through 10 again.

- If the device responds, proceed to step 18.

Download the BTS

Overview

Download the BTS68P09255A69-3

Before a BTS can operate, each equipped device must contain device initialization (ROM) code. ROM code is loaded in all devices during manufacture, factory repair, or, for software upgrades, from the CBSC using the DownLoad Manager (DLM). 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 or a normal part of the optimization process. It is only

done in unusual situations where the resident ROM code release level in the device is not compatible with the required release level of the site operating software and the CBSC can not communicate with the BTS to perform the download. An example would be a BTS loaded with R16.0 software where a GLI which is factory-loaded with R9.2.x or earlier ROM code must be installed to replace a malfunctioning GLI.

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.

NOTE

The ROM code file is not available for GLI3s. GLI3s are ROM code loaded at the factory.

ROM code can be downloaded to a device that is in any state. After the download is started, the device being downloaded will change to OOS_ROM (blue). The device will remain OOS_ROM (blue) when the download is completed. A compatible revision-level RAM code must then be downloaded to the device. Compatible code loads for ROM and RAM must be used for the device type to ensure proper performance. The compatible device code release levels for the BSS software release being used are listed in the Version Matrix section of the SC CDMA Release Notes (supplied on the tape or CD-ROM containing the BSS software).

Procedures to load ROM code are located in Appendix G.

RAM Code

Before RAM code can be downloaded from the 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 LMF file structure. The RAM code file will be selected automatically if the file is in the <x>:\<lmf home directory>\cdma\loads\n.n.n.n\code folder (where n.n.n.n is the download code version number that matches the “NextLoad” parameter of the CDF file). The RAM code file in the code folder must have the correct hardware bin number for the device to be loaded.

RAM code can be downloaded to a device that is in any state. After the download is started, the device being loaded will change to OOS_ROM (blue). When the download is completed successfully, the device will change to OOS_RAM (yellow).

Download the BTS

When code is downloaded to an MGLI or GLI, the LMF automatically also downloads data and then enables the MGLI. When enabled, the MGLI will change to INS_ACT (bright green). A redundant GLI will not be automatically enabled and will remain OOS_RAM (yellow). When the redundant GLI is manually commanded to enable through the LMF, it will change state to INS_SBY (olive green).

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

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

 Master Group Line Interface (MGLI)

68P09255A69-3

 Redundant GLI  Clock Synchronization Module (CSM) (Only if new revision code

must be loaded)

 Multi Channel CDMA (MCC24E, MCC8E, or MCC-1X) cards  Broadband Transceiver (BBX2 or BBX-1X) cards  RFDS Test Subscriber Interface Card (TSIC) or RFDS-1X RFDS

PROCessor (RPROC) card, if RFDS is installed

NOTE

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

Verify GLI ROM Code Loads

Devices should not be loaded with a RAM code version which is not compatible with the ROM code with which they are loaded. Before downloading RAM code and data to the processor cards, follow the procedure in Table 3-17 to verify the GLI devices are loaded with the correct ROM code for the software release used by the BSS.

Prerequisite

Identify the correct GLI ROM code load for the software release being used on the BSS by referring to the Version Matrix section of the SC CDMA Release Notes (supplied on the tapes or CD-ROMs containing the BSS software).

Table 3-17: Verify GLI ROM Code Loads

NOTE

The GPS satellite system satellites are not in a geosynchronous orbit and are maintained and operated by the United States Department of Defense (DOD). The DOD periodically alters satellite orbits; therefore, satellite trajectories are subject to change. A GPS receiver that is INS contains an ephemeris (satellite position table) 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 ephemeris 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).

NOTE

CSM System Time - GPS & LFR/HSO Verification

68P09255A69-3

CSM System Time - GPS & LFR/HSO Verification

Clock Synchronization Manager (CSM) Sub-system Description

Overview - Each BTS CSM sub-system features two CSM boards per RFMF. The primary function of the CSM cards is to maintain CDMA system time. GPS is used as the primary timing reference and synchronizes the entire cellular system. In typical operation, the primary CSM locks its Digital Phase Locked Loop (DPLL) circuits to GPS signals. These signals are provided by either an on-board GPS receiver

module (RF-GPS) or a remote GPS receiver (RGPS). RGPS uses a GPS receiver in the antenna head that has a digital output. The second generation CSM card (CSM-II) is required when using the RGPS. A CSM-II card can also be equipped with a local GPS receiver daughter card to support an RF-GPS signal.

SCCP Shelf CSM Card Slot Assignments - The GPS receiver is interfaced to the board in SCCP shelf slot CSM 1. This card is the primary timing source, while the card in slot CSM 2 provides redundancy. The redundant card, does not have a GPS receiver.

CSM-II Card Type Description - Each CSM-II card features a temperature-stabilized crystal oscillator that provides 19.6608 MHz clock, even second pulse, and 3 MHz reference signals to the synchronization source selected from the following (refer to Table 3-24 for source selection/verification procedures):

 GPS: local/RF-GPS or remote/RGPS  LORAN-C Low Frequency Receiver (LFR) or High Stability

Oscillator (HSO)

 External reference oscillator sources

CDMA Clock Distribution Card (CCD) Description - CCD cards buffer and distribute even-second reference and 19.6608 MHz clock signals from the CSM cards. CCD 1 is married to the card in slot CSM 1, and CCD 2 is married to the card in slot CSM 2.

CSM Card Redundancy - The BTS switches between the primary and redundant units (card slots CSM 1 and CSM 2, respectively) upon failure or command. A failure in CSM 1 or CCD 1 will cause the system to switch to the CSM 2-CCD 2 redundant card pair. GPS timing synchronization is continually maintained between the primary and redundant CSM-CCD pairs.

3-38

Secondary Timing References - The BTS may be equipped with a LORAN-C Low Frequency Receiver (LFR), a High Stability Oscillator (HSO), or external 10 MHz Rubidium source which the CSM can use as a secondary timing reference. Continuous GPS synchronization is maintained for the LFR or HSO secondary timing references. The CSM monitors and determines what reference to use at a given time.

Low Frequency Receiver/ High Stability Oscillator

CSM System Time - GPS & LFR/HSO Verification68P09255A69-3

Timing Source Fault Management - 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. During normal operation, the card in slot CSM 1 selects GPS as the primary timing source (Table 3-24). The source selection can also be overridden via the LMF or by the system software.

General

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

LFR - The LFR requires an active external antenna to receive LORAN-C 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.

HSO - 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

The LFR2 and HSO2 (second generation cards) both can export a timing signal to other BTS frames located at a site. These secondary frames require an HSO-expansion (HSOX) module whether the primary frame has an LFR2 or an HSO2. The HSOX accepts input from the primary frame and interfaces with the CSM cards in the secondary frames. LFR and LFR2 use the same source code in source selection (Table 3-24). HSO, HSO2, and HSOX use the same source code in source selection (Table 3-24).

Aug 2002

NOTE

1X SC4812ET Lite BTS Optimization/ATP Software Release 2.16.1.x

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

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

NOTE

WARNING

Warm-up BTS equipment for a minimum of 60 minutes prior to performing the BTS optimization procedure. This assures BTS stability and contributes to optimization accuracy.

- Time spent running initial or normal power-up, hardware/firmware audit, and BTS download counts as warm-up time.

Before installing any test equipment directly to any BTS TX OUT connector, verify there are no CDMA channels keyed.

- At active sites, have the OMC-R/CBSC place the antenna (sector) assigned to the BBX under test OOS. Failure to do so can result in serious personal injury and/or equipment damage.

Test Set Calibration

Background

Test Set Calibration68P09255A69-3

Proper test equipment calibration helps to ensure accurate BTS optimization and acceptance testing by assuring that the test equipment and associated cables do not introduce measurement errors.

NOTE

CAUTION

NOTE

If the test equipment set (see the Terms and Abbreviations section of Chapter 1) being used to optimize or test the BTS has been calibrated and maintained as a set, this procedure does not need to be performed.

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

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

Calibration of the communications system analyzer (or equivalent test equipment) must be performed at the site before calibrating the overall test equipment set. Calibrate the test equipment after it has been allowed to warm-up and stabilize for a a minimum of 60 minutes.

Calibration Procedures Included

Automatic

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

Manual

Agilent E4406A Transmitter Tester - The E4406A does not support the power level zeroing calibration performed by the LMF. If this instrument is to be used for Bay Level Offset calibration and calibration is attempted with the LMF Calibrate Test Equipment function, the LMF will return a status window failure message stating that zeroing power is not supported by the E4406A. Refer to the Equipment Calibration section of Appendix F for instructions on using the instrument’s self-alignment (calibration) function prior to performing Bay Level Offset calibration.

Test Set Calibration

GPIB Addresses

68P09255A69-3

Power Meters - Manual power meter calibration procedures to be performed prior to automated calibration are included in the Equipment Calibration section of Appendix F.

Cable Calibration - Manual cable calibration procedures using the HP 8921A and Advantest R3465 communications system analyzers are provided in the Manual Cable Calibration section of Appendix F, if needed.

GPIB addresses can range from 1 through 30. The LMF will accept any address in that range, but the numbers entered in the LMF Options window GPIB address boxes (Table 3-28 and Table 3-29) must match the addresses set in the test equipment. Motorola recommends using 1 for a CDMA signal generator, 13 for a power meter, and 18 for a communications system analyzer. To verify and, if necessary, change the GPIB addresses of the test equipment, refer to the Setting GPIB Addresses section of Appendix NO TAG.

Selecting Test Equipment

Serial Connection and Network Connection tabs are provided in the LMF Options window to specify the test equipment connection method.

The Serial Connection tab is used when the test equipment items are connected directly to the LMF computer through 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

Be sure the following have been completed before selecting test equipment:

 Test equipment is turned on.

3-66

 GPIB addresses set in the test equipment have been verified as correct

using the applicable procedures in Appendix NO TAG.

 LMF computer serial port and test equipment are connected to the

GPIB box.

Selecting Test Equipment

Test equipment may be selected either manually with operator input or automatically using the LMF autodetect feature.

Test Set Calibration68P09255A69-3

Manually Selecting Test Equipment in a Serial Connection Tab

Test equipment can be manually specified before or after the test equipment is connected. The LMF does not attempt to verify the test equipment is actually detected when manual selection is specified. Follow the procedure in Table 3-28 to manually select test equipment.

Table 3-28: Selecting Test Equipment Manually in the Serial Connection Tab

Step Action

1 In the LMF window menu bar, click Tools and select Options... from the pull-down menu.

- The LMF Options window appears. 2 If it is not in the forefront, click on the Serial Connection tab. 3 Select the correct serial port in the COMM Port: pick list (normally COM1). 4 If it is not selected (black dot showing), click on the Manual Specification button. 5 Click on the check box(es) corresponding to the test equipment item(s) to be used.

Type the GPIB address in the corresponding GPIB address box (refer to the Setting GPIB Addresses

section of Appendix NO TAG for directions on verifying and/or changing test equipment GPIB addresses).

Motorola-recommended addresses are:

1 = signal generator 13 = power meter 18 = communications system analyzer

NOTE

When test equipment items are manually selected by the operator, the LMF defaults to using a power meter for RF power measurements. The LMF will use a communications system analyzer for RF power measurements only if a power meter is not selected (power meter checkbox not checked).

7 Click on Apply.

- The button will darken until the selection has been recorded.

NOTE

With manual selection, the LMF does not attempt to detect the test equipment to verify it is connected and communicating with the LMF.

8 Click on Dismiss to close the LMF Options window.

Calibrating Cables - Overview

The LMF Cable Calibration function is used to measure the path loss (in dB) for the TX and RX cables, adapters, directional couplers, and attenuators that make up the cable configurations used for testing. A communications system analyzer is used to measure the loss of both the TX test cable and the RX test cable configurations. LMF cable calibration consists of the following processes:

1. Measure the loss of a short cable. This is done to compensate for any measurement error of the communications system analyzer. The short cable, which is used only for the calibration process, is connected in series with both the TX and RX test cable configurations when they are measured. The measured loss of the short cable is deducted from the measured loss of the TX and RX test cable configurations to determine the actual loss of the configurations. This deduction is done so any error in the analyzer measurement will be adjusted out of both the TX and RX measurements.

Test Set Calibration

2. Measure the loss of the short cable plus the RX test cable configuration. The RX test cable configuration normally consists only of a coax cable with type-N connectors that is long enough to reach from the BTS RX connector to the test equipment. When the BTS antenna connectors carry duplexed TX and RX signals, a directional coupler and, if required by BTS type, an additional attenuator are also required for the RX test cable configuration. These additional items must be included in the path loss measurement.

3. Measure the loss of the short cable plus the TX test cable configuration. The TX test cable configuration normally consists of

two coax cables with type-N connectors, a directional coupler, a termination load with sufficient rating to dissipate the BTS output power, and an additional attenuator, if required by the BTS type. The total path loss of the TX test configuration must be as required for the BTS (normally 30 or 50 dB). The Motorola Cybertest analyzer is different from other communications system analyzers because the required attenuation/load is built into the test set. Because of this, the Cybertest TX test configuration consists only of the required length coax cable.

Bay Level Offset Calibration

68P09255A69-3

Bay Level Offset Calibration

Purpose of Bay Level Offset Calibration

Bay Level Offset (BLO) calibration is the central activity of the optimization process. BLO calibration compensates for normal equipment variations within the BTS RF paths and assures the correct transmit power is available at the BTS antenna connectors to meet site performance requirements.

What is BLO Calibration?

Description

BLO calibration is the complete title of what is normally referred to as “calibration.” Calibration identifies the accumulated gain in every transmit path at the BTS site. The transmit path BLO values determined during calibration are stored in the LMF calibration data file, and are subsequently downloaded to each BBX. When transmit path calibration is performed, receive path BLO values will automatically be set to the default value in the LMF calibration file and downloaded.

BTS RF Path Descriptions

Transmit (TX) path - A TX path starts at an SCCP shelf BBX backplane slot, travels through the CIO card, is routed to the Linear Power Amplifier (LPA) trunking module for sector phase shifting, through the LPAs, back through the LPA trunking module for sector phase selection, through the TX bandpass filter (starter frames) or 2:1 TX combiner (companion frames), through the Transmit & Receive Dual Directional Coupler (TRDC) or Duplexer Directional Coupler (DRDC), and ends at the TRDC TX or DRDC antenna connector.

Receive (RX) main path - A main RX path starts at ANTENNAS connectors 1A, 2A, or 3A and travels through the associated TRDC or DRDC, the MPC in SCCP cage slot MPC-1, the CIO card, and terminates at a backplane BBX slot in the SCCP shelf.

Diversity RX path - Diversity RX paths differ for SC4812ET Lite starter (stand-alone) and companion frames. The following describe each type of path:

 Starter frame diversity RX path - A starter frame diversity RX path

is the same as a main RX path except that it starts at ANTENNAS connectors 1B, 2B, or 3B, travels through the associated TRDC or DRDC, and the MPC card in SCCP cage slot MPC-2 (refer to Table 1-5).

 Companion frame diversity RX path - The companion frame main

RX signal is used for the collocated companion frame diversity RX signal. A companion frame’s diversity RX path starts at ANTENNAS connectors 1A, 2A, or 3A in the collocated companion frame. It travels through the associated TRDC or DRDC, the MPC in SCCP cage slot MPC-1, and the CIO card where it is then routed out of the

frame through the RX expansion out connectors (RX EXPANSION 1A, 2A, or 3A in Figure 1-9 or Figure 1-10). The signal travels through the inter-frame diversity RX cables, into the RX expansion in ports (RX EXPANSION 1B, 2B, or 3B in Figure 1-9 or Figure 1-10) of the companion frame, through the Expansion MPC (EMPC) in SCCP cage slot MPC-2, the CIO, and terminates at a backplane BBX slot in the SCCP shelf.

 RFDS sampling paths - Directional couplers for RFDS signal

sampling are integral to the SC4812ET Lite transmit and receive paths in the DRDCs and TRDCs. Cables connect from these directional couplers to the RFDS input connectors.

Component Verification During Calibration

TX Path Calibration

TX path calibration supports verification of correct BTS installation, RF cabling installation and performance, functionality of all equipment installed in the transmit RF chain, and the proper functioning of each transmit RF path. External test equipment is used to calibrate and audit the TX paths of the BTS.

RX Path Calibration

RX path calibration is not required or supported on CDMA BTS systems. Default RX calibration values are written to the RX calibration data files during the TX calibration process. RX functionality is verified during Frame Erasure Rate (FER) testing.

When to Calibrate

Calibration to determine BLO:

1. Is required after initial BTS installation.

2. Must be done once each year for an operational BTS site.

3. Is recommended by Motorola for all associated RF paths after replacing any of the following components:

- BBX card

- SCCP shelf

- CIO card

- CIO-to-LP A trunking module RF cable

- LPA trunking module

-LPA

- Trunking module-to-TX filter/filter combiner RF cable

- DRDC or TRDC

BLO Calibration Data File

Aug 2002

1X SC4812ET Lite BTS Optimization/ATP Software Release 2.16.1.x

During the calibration process, the LMF creates a calibration (CAL) data file where BLO values are stored. After calibration has been completed, these offset values must be downloaded to the BBXs using the LMF BLO download function. A detailed description of the file organization and content is provided in the following paragraphs

3-77

PRELIMINARY

Bay Level Offset Calibration

68P09255A69-3

NOTE

Due to the size of the file, Motorola recommends printing out a copy of a

bts- #.cal file and referring to it for the following

descriptions.

CAL File Organization

The CAL file is subdivided into three sections called “slot Blocks”. These are:

1. Slot[1] Block which contains the calibration data for the six primary BBX slots.

2. Slot[20] Block which contains the calibration data for the redundant

BBX (see Table 3-37).

3. Slot[385] Block which contains the calibration data for the RFDS.

BBX Slot Block Parts

BBX slot Blocks are further subdivided into the parts described in the following:

Slot Block Header - Each BBX slot Block has a header section (slot header) which contains:

 A creation Date and Time - broken down into separate parameters of

createMonth, createDay, createYear, createHour, and createMin.

 The number of calibration entries in the file - the numBayLevelPts

parameter. The parameter is fixed at 720 entries for SC4812-series frames. These 720 entries are combined to define the 360 calibration points of the CAL file.

 The slot Block format parameter.

Slot Block Bay Level Calibration Data - Each BBX slot Block has a Bay Level Calibration data section (BayLevelCal) which is organized as a large flat array. The array is organized by branch, SCCP cage BBX slot, and calibration entries. There are several ways to look at the array contents. Two different views are provided in the following to illustrate the significant features of BayLevelCal section content and organization:

 The first view of the array is shown in Table 3-36. This view shows

- The first entry for a calibration point (all odd entries) identifies the CDMA channel (frequency) where the BLO is measured. The second calibration entry (all even entries) is the power set level (PwrLvlAdj) for that frequency. The valid range for PwrLvlAdj is

from 2500 to 27500 (2500 corresponds to -125 dBm and 27500 corresponds to +125 dBm).

- The ten calibration points for each slot-branch combination must be stored in order of increasing frequency. If less than ten points (frequencies) are calibrated, the BLO data for the highest frequency calibrated is written into the remainder of the ten points for that slot-branch.

Example:

C[1]=384

(odd cal entry)

= 1 “calibration point”

C[2]=19102 (even cal entry)

C[3]=777 (odd cal entry)

= 1 “calibration point”

C[4]=19086 (even cal entry)

. . .

C[19]=777 (odd cal entry)

= 1 “calibration point”

C[20]=19086 (even cal entry)

In the example above, BLO was measured at only two frequencies (channels 384 and 777) for SCCP slot BBX-1 transmit (Table 3-37). The BLO data for the highest frequency measured (channel 777) will be written to the remaining eight transmit calibration points (defined by entries C[5] through C[20]) for BBX-1.

Slot Block Temperature Compensation - Each BBX slot Block also has a temperature compensation data section (TempLevelCal) where power level compensation factors for temperature variations are stored.

CAL File and BLO Data Download

When BLO data is downloaded to the BBXs after calibration, the data is downloaded to the devices in the order it is stored in the CAL file. TX calibration data (entries C[1] - C[60]) are sent first. Data for the ten BBX slot 1 calibration points (entries C[1] - C[20]) are sent initially, followed by data for the ten BBX slot 2 calibration points (entries C[21]

- C[40]), and so on. The RX calibration data is sent next in BBX slot sequence, followed by RX Diversity calibration data.

To prevent damage to the test equipment, all transmit (TX) test connections must be via the 30 dB

directional coupler for 800 MHz or via a 30 dB coupler with a 20 dB in-line attenuator for 1900

MHz.

For TX path calibration, connect the test equipment as shown in Figure 3-13, Figure 3-14, or

Figure 3-15, depending on the communications analyzer being used.

Transmit (TX) Path Calibration Description

The assigned channel frequency and desired power level at the frame TX ports for transmit calibration are derived from the BTS CDF file. Each BBX at the site is assigned to a sector and carrier. These are specified respectively in the sector and carrier fields of the parameter in each BBXs CDF file block. The channel frequency and desired power for the assigned sector are specified respectively in the

ChannelList and SIFPilotPwr parameters of the CDF block for the

CARRIER to which the BBX is assigned.

NOTE

Be sure the bts-#.cdf and cbsc-#.cdf files loaded on the LMF computer are current. The LMF will obtain carrier and channel information from these files and insert it into the appropriate CDMA Test Parameter screen. Failure to have the most current files from the CBSC can result in incorrect channel information being used to calibrate the BTS and unfavorable affects on BTS performance. Carrier and channel numbers should only be entered manually for special test cases or as a last resort.

ParentCARRIER

The calibration process attempts to adjust the measured power to within

0.5 dB of the desired power. The calibration will pass if the error is less

1.5 dB.

than + The TX BLO for the SC4812ET Lite is approximately 42.0 dB ±5.0 dB.

BLO is the gain in dB between the known power output of the BBX and the measured power at the TX port. BLO is derived by deducting the known BBX power output from the power measured at the TX port or (Measured Power) - (BBX TX Power Output).

Example:

Measured Power (at TX port) = 36.0 dBm Known BBX TX Power Output = -6.0 dBm BLO = (36.0) - (-6.0) = 42.0 dB gain

TX Calibration and the LMF

The LMF Tests > TX > TX Calibration... and Tests > All Cal/Audit... selections perform TX BLO calibration testing for installed BBX(s). The All Cal/Audit... selection initiates a series of actions to perform TX calibration, and if calibration is successful, download BLO and perform TX audit. The TX Calibration... selection performs only TX calibration. When TX Calibration... is used, BLO download and TX audit must be performed as separate activities. The CDMA Test Parameters window which opens when TX Calibration... or All Cal/Audit... is selected contains several user-selectable features which

are described in the following subsections.

Rate Set Drop-down Pick List

The Rate Set Drop-down Box is enabled if at least one MCC card is selected for the test. The available options for TX tests are 1 = 9600, and 3 = 9600 1X. Option 3 is only available if 1X cards are selected for the test. The available transfer rate options for RX tests are 1 = 9600 and 2 = 14400. Option 2 is only available if no 1X cards are selected.

Verify BLO Checkbox

A Verify BLO checkbox is provided and checked by default. After the actual TX calibration is completed, the BLO derived from the calibration is compared to a standard, acceptable BLO tolerance for the BTS. In some installations, additional items may be installed in the transmit path. The additional change in gain from these items could cause BLO verification failure and, therefore, failure of the entire calibration. In these cases, either the Verify BLO checkbox should be unchecked or the additional path losses should be added into each applicable sector using the Util > Edit > TX Coupler Loss... function.

Single-Sided BLO Checkbox

An acceptable range of BLO values for each type of BTS is established to allow for tolerance variations in all the components of the RF chain. This acceptable range, 42+ accommodate the redundant BBX in the BTS. This is a much wider tolerance than necessary for the primary BBXs. Primary BBXs normally will have BLOs in the lower half of the range. Using the example range, this would be from 37 to 42 dB. Checking the Single-Sided BLO checkbox should only be done when calibrating primary BBXs because it will reduce the acceptable BLO value variations to the lower half of the range. Because this is a much more stringent tolerance, calibrations run with Single-Sided BLO are more likely to fail and should only be attempted by an experienced CFE. Never select Single-Sided BLO when calibrating a redundant BBX.

5 dB for example, is very wide to

WARNING

CAUTION

NOTE

Before installing any test equipment directly to any BTS TX OUT connector, first verify no CDMA channels are keyed.

Failure to do so can result in serious personal injury and/or equipment damage.

Always wear an approved anti-static wrist strap while handling any circuit card or module. If this is not done, there is a high probability that the card or module could be damaged by ESD.

At new site installations, to facilitate the complete test of each SCCP 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).

Calibration Audit Introduction

The BLO calibration audit procedure confirms the successful generation and storage of the BLO calibration values. The calibration audit procedure measures the path gain or loss of every BBX transmit path at the site. In this test, actual system tolerances are used to determine the success or failure of a test. The same external test equipment set-up required for TX calibration is used for TX audit.

IMPORTANT

RF path verification, BLO calibration, and BLO data download to BBXs must have been successfully completed prior to performing the calibration audit.

TX Path Audit

Perform the calibration audit of the TX paths of all equipped BBX slots, per the steps in Table 3-43.

RFDS Calibration

RFDS Set-up and Calibration68P09255A69-3

The RFDS Calibration option is used to calibrate the RFDS TX and RX paths.

TX Path Calibration - For a TX antenna path calibration the BTS XCVR is keyed at a pre-determined power level and the BTS power output level is measured by the RFDS. The power level is then measured at the TX antenna directional coupler by the power measuring test equipment item being used (power meter or analyzer). The difference (offset) between the power level at the RFDS and the power level at the TX antenna directional coupler is used as the TX RFDS calibration offset value.

RX Path Calibration - For an RX antenna path calibration the RFDS is keyed at a pre-determined power level and the power input level is measured by the BTS BBX. A CDMA signal at the same power level measured by the BTS BBX is then injected at the RX antenna directional coupler by the communications system analyzer. The difference (offset) between the RFDS-keyed power level and power level measured at the BTS BBX is the RFDS RX calibration offset value.

RFDS calibration and the CAL file - The TX and RX RFDS calibration offset values are written to the CAL file in the slot[385] Block.

TSIC channel frequency - For each RFDS TSIC, the channel frequency is determined at the lower third and upper third of the appropriate band using the frequencies listed in Table 3-50.

Table 3-50: RFDS TSIC Calibration Channel Frequencies

System Channel Calibration Points

800 MHz (A and B) 341 and 682

1.9 GHz 408 and 791

WARNING

Before installing any test equipment directly to any TX OUT connector, verify that there are no CDMA channels

keyed. Failure to do so can result in serious personal injury and/or equipment damage.
