Command Line Interface Overview

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

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

The CLI handler is already running. This may cause conflicts with the LMF. Are you sure you want to start the application? Yes No

Using the LMF68P09258A31–A

This window also contains Yes and No buttons. Selecting Ye s starts the application. Selecting No terminates the application.

CLI Format Conventions

The CLI command syntax is as follows:

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

– keywords

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

– parameter values

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

measure bbx–<bts_id>–<bbx_id> rssi channel=6 sector=5

Refer to LMF CLI Commands for a complete explanation of the CLI commands and their usage.

Logging into a BTS

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:

S The LMF is correctly installed on the LMF computer.

S A bts-nnn folder with the correct CDF/NECF and CBSC files exists. S 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 3-5 and Figure 3-3.

CAUTION

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

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

Download the BTS

Overview

Download the BTS68P09258A31–A

Before a BTS can operate, each equipped device must contain device initialization (ROM) code. ROM code is loaded in all devices during manufacture or factory repair, 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

NOTE

Downloading ROM code to BTS devices from the LMF is NOT routine maintenance nor a normal part of the optimization process. It is only

done in unusual situations where the resident ROM code in the device does not match the release level of the site operating software AND the CBSC cannot communicate with the BTS to perform the download.

If you must download ROM code, the procedures are located in

Appendix G.

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.

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 SCt CDMA Release Notes (supplied on the tape or CD–ROM containing the BSS software).

RAM Code

Oct 2003

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 downloaded changes to OOS-ROM (blue). When the download is completed successfully, the device will change to OOS-RAM (yellow).

Download the BTS

68P09258A31–A

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–MGLI 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:

S Master Group Line Interface (MGLI2 or MGLI3) S Redundant GLI (GLI2 or GLI3) S Clock Synchronization Module (CSM) (Only if new revision code

must be loaded)

S Multi Channel Card (MCC24E, MCC8E or MCC–1X) S Broadband Transceiver (BBX2 or BBX–1X) S Test Subscriber Interface Card (TSIC) – if RFDS is installed

NOTE

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

Enable CSMs

Download the BTS68P09258A31–A

NOTE

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

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

– The CSM(s) to be enabled must have been downloaded

with code (Yellow, OOS–RAM) and data.

Each BTS CSM system features two CSM boards per site. In a typical operation, the primary CSM locks its Digital Phase Locked Loop (DPLL) circuits to GPS signals. These signals are generated by either an on–board GPS module (RF–GPS) or a remote GPS receiver (R–GPS). The CSM2 card is required when using the R–GPS. The GPS receiver (mounted on CSM–1) is the primary timing reference and synchronizes the entire cellular system. CSM–2 provides redundancy but does not have a GPS receiver.

The BTS may be equipped with a remote GPS, LORAN–C LFR, HSO 10 MHz Rubidium source, or HSOX for expansion frames, 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.

Follow the procedure in Table 3-16 to enable the CSMs.

Table 3-16: Enable CSMs

n Step Action

1 Click on the target CSM (CSM–2 first, if equipped with two CSMs).

2 From the Device pull down, select Enable.

– A status report is displayed confirming change in the device(s) status.

– Click OK to close the status report window.

NOTE

– The board in slot CSM 1 interfaces with the GPS receiver. The enable sequence for this board can

take up to one hour (see below).

– FAIL may be shown in the status report table for a slot CSM 1 enable action. If

Lock is shown in the Description field, the CSM changes to the Enabled state after phase lock is

achieved.

* 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 Verification68P09258A31–A

CSM System Time – GPS & LFR/HSO Verification

CSM & LFR Background

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

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

In a typical operation, the primary CSM locks its Digital Phase Locked Loop (DPLL) circuits to GPS signals. These signals are generated by either an on–board GPS module (RF–GPS) or a remote GPS receiver (R–GPS). The CSM2 card is required when using the R–GPS. DPLL circuits employed by the CSM provide switching between the primary and redundant unit upon request. Synchronization between the primary and redundant CSM cards, as well as the LFR or HSO back–up source, provides excellent reliability and performance.

Front Panel LEDs

Each CSM board features an ovenized, crystal oscillator that provides

19.6608 MHz clock, even second tick reference, and 3 MHz sinewave reference, referenced to the selected synchronization source (GPS, LORAN–C Frequency Receiver (LFR), or High Stability Oscillator (HSO), T1 Span, or external reference oscillator sources).

The 3 MHz signals are also routed to the RDM EXP 1A & 1B connectors on the top interconnect panel for distribution to co–located frames at the site.

Fault management has the capability of switching between the GPS synchronization source and the LFR/HSO backup source in the event of a GPS receiver failure on CSM–1. During normal operation, the CSM–1 board selects GPS as the primary source (see Table 3-20). The source selection can also be overridden via the LMF or by the system software.

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

S Steady Green – Master CSM locked to GPS or LFR (INS). S Rapidly Flashing Green – Standby CSM locked to GPS or LFR

(STBY).

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

to lock on GPS signal.

S Rapidly Flashing Green and Red – Alarm condition exists. Trouble

Notifications (TNs) are currently being reported to the GLI.

Low Frequency Receiver/High Stability Oscillator (LFR/HSO)

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

NOTE

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).

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 GPIB Address Settings

All test equipment is controlled by the LMF through an IEEE–488/GPIB bus. To communicate on the bus, each piece of test equipment must have a GPIB address set which the LMF will recognize. The standard address settings used by the LMF for the various types of test equipment items are as follows:

3-56

S Signal generator address: 1 S Power meter address: 13 S Communications system analyzer: 18

Using the procedures included in the Verifying and Setting GPIB Addresses section of Appendix F, verify and, if necessary, change the GPIB address of each piece of employed test equipment to match the applicable addresses above

Test Equipment Preparation

S Agilent 8935 series E6380A communications test set (formerly HP

8935) with option 200 or R2K and with E4432B signal generator for 1X FER

The E4406A/E4432B pair, or the R3267/R3562 pair, should be connected together using a GPIB cable. In addition, the R3562 and R3267 should be connected with a serial cable from the Serial I/O to the Serial I/O. This test equipment is capable of performing tests in both IS–95 A/B mode and CDMA 2000 mode if the required options are installed.

S Agilent E7495A communications test set

Optional test equipment

S Spectrum Analyzer (HP8594E) – can be used to perform cable

calibration.

See Appendix F for specific steps to prepare each type of test set and power meter to perform calibration and ATP.

Equipment Warm-up

68P09258A31–A

NOTE

WARNING

To assure BTS stability and contribute to optimization accuracy of the BTS, warm-up the BTS test equipment prior to performing the BTS optimization procedure as follows:

– Agilent E7495A for a minimum of 30 minutes

– All other test sets for a minimum of 60 minutes

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

Automatic Cable Calibration Set–up

Figure 3-12 through Figure 3-15 show the cable calibration setup for various supported test sets. The left side of the diagram depicts the location of the input and output ports of each test set, and the right side details the set up for each test.

Manual Cable Calibration

If manual cable calibration is required, refer to the procedures in Appendix F.

Test Set Calibration

Background

68P09258A31–A

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

NOTE

CAUTION

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 equipment set being used to optimize or test the BTS has been calibrated and maintained as a set, this procedure does not need to be performed.

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 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.

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

Calibrating Cables Overview

Test Set Calibration68P09258A31–A

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:

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 TX and RX test cable configurations minus the measured loss of the short cable equals the actual loss of the configurations. This is done so that any error in the analyzer measurement is eliminated from both the TX and RX measurements.

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 is required and an additional attenuator may also be required (for certain BTS types) for the RX test cable configuration. These additional items must be included in the path loss measurement.

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 differs 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

Introduction

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.

RF Path Bay Level Offset Calibration

Bay Level Offset Calibration68P09258A31–A

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

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

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

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

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

When to Calibrate BLOs

Oct 2003

Calibration of BLOs is required:

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

interconnecting RF cabling: – BBX board – C–CCP shelf – CIO card – CIO to Power Amplifier backplane RF cable – PA backplane –PA – TX filter / TX filter combiner – TX thru-port cable to the top of frame

1X SCt 4812T BTS Optimization/ATP

3-85

Bay Level Offset Calibration

TX Path Calibration

68P09258A31–A

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

NOTE

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.

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

– This procedure can be bypassed on operational sites that are

due for periodic optimization.

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

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

BLO Calibration Data File

NOTE

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

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

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

createMonth, createDay, createYear, createHour, and createMin.

S 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.

S Ten calibration points per sector are supported for each branch. Two

entries are required for each calibration point.

S The first value (all odd entries) refer to the CDMA channel

(frequency) where the BLO is measured. The second value (all even entries) is the power set level. The valid range for PwrLvlAdj is from 2500 to 27500 (2500 corresponds to –125 dBm and 27500 corresponds to +125 dBm).

S The 20 calibration entries for each sector/branch combination must be

stored in order of increasing frequency. If less than 10 points (frequencies) are calibrated, the largest frequency that is calibrated is repeated to fill out the 10 points.

Example:

C[1]=384, odd cal entry

= 1 ‘‘calibration point”

C[2]=19102, even cal entry

C[3]=777, C[4]=19086, . . C[19]=777, C[20]=19086, (since only two cal points were calibrated this

would be repeated for the next 8 points)

S When the BBX is loaded with image = data, the cal file data for the

BBX is downloaded to the device in the order it is stored in the cal file. TxCal data is sent first, C[1] – C[240]. Sector 1’s ten calibration points are sent (C[1] – C[20]) followed by sector 2’s ten calibration points (C[21] – C[40]), etc. The RxCal data is sent next (C[241] – C[480]), followed by the RxDCal data (C[481] – C[720]).

Test Equipment Set-up for RF Path Calibration

Follow the procedure in Table 3-35 to set up test equipment.

Table 3-35: Set Up Test Equipment for RF Path Calibration

Step Action

1 If it has not already been done, refer to the procedure in Table 3-5 (on page 3-17) to interface the LMF

computer terminal to the frame LAN A connector.

2 If it has not already been done, refer to Table 3-6 (on page 3-26) to start a GUI LMF session.

3 If required, calibrate the test equipment per the procedure in Table 3-27 (on page 3-78).

NOTE

Verify the GPIB controller is properly connected and turned on.

! CAUTION

To prevent damage to the test equipment, all transmit (TX) test connections must be via the 30 dB directional coupler for 800 MHz with an additional 20 dB in–line attenuator for 1.7/1.9 GHz.

4 For TX path calibration, connect the test equipment as shown in Figure 3-16, Figure 3-17, or

Figure 3-19, depending on the communications analyzer being used.

Transmit (TX) Path Calibration Description

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

ParentSECTOR field of the ParentCARRIER CDF file

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

NOTE

under the parameter).

The calibration procedure attempts to adjust the power to within +0.5 dB 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.

S At sites WITHOUT RFDS option, BLO is approximately

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

ChannelList

Oct 2003

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

S 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.

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

In both the TX Calibration and All Cal/Audit dialog boxes, a Verify BLO checkbox is provided and checked by default. After the actual TX calibration is completed during either the TX Calibration or All Cal/Audit process, 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.

3-90

Single-Sided BLO Checkbox

Another option that appears in the pull–down menu is Single–sided BLO. Normally valid BLO values are some value plus–or–minus some

offset. The ranges that we currently use for calibration are wider than necessary to accommodate the redundant BBX. The lower half of that range is where non–redundant BBXs should be. When Single–sided BLO is selected, the result is only considered a success if it is in the lower half of the range. If it was normally a success from 37–47 (which is 42 "5), Single–sided BLO would make it a success only if the result was from 37–42. To get the more stringent conditions, the operator checks Single–sided BLO when calibrating non–redundant transceivers. Single–sided BLO carries the likelihood of more failures. This option should only be used by experienced CFEs.

Test Pattern Drop-down Pick List

The Tests > TX > TX Calibration... menu window has a Test Pattern pull–down menu. This menu has the following choices:

S Pilot (default) – performs tests using a pilot signal only. This pattern

should be used when running in–service tests. It only requires a BBX to do the test.

S Standard – performs the tests using pilot, synch, paging and six

traffic channels. This pattern should be used on all non–in–service tests. Standard requires a BBX and an MCC. Standard uses gain values specified by the IS97 standard.

S CDFPilot –performs the tests using the pilot signal, however, the gain

is specified in the CDF file. Advanced users may use CDFPilot to generate a Pilot pattern using the value specified by the PilotGain parameter in the CDF file instead of a pre–determined value.

S CDF – performs the tests using pilot, synch, paging and six traffic

channels, however, the gain for the channel elements is specified in the CDF file. Advanced users may use CDF to generate a standard pattern. Instead of using the values specified by IS97, the settings for the following CDF parameters are used:

RFDS Description

RFDS Set–up and Calibration68P09258A31–A

NOTE

RFDS Parameter Settings

The RFDS is not available for the –48 V BTS at the time of this publication.

The optional RFDS performs RF tests of the site from the CBSC or from an LMF. The RFDS consists of the following elements:

S Antenna Select Unit (ASU) S Fixed Wireless Terminal Interface Card (FWTIC) S Subscriber Unit Assembly (SUA)

For complete information regarding the RFDS, refer to the CDMA

CDMA RFDS Hardware Installation; 68P64113A93, CDMA RFDS User’s Guide; 68P64114A51, and the LMF Help function on–line documentation.

The bts–#.cdf file includes RFDS parameter settings that must match the installed RFDS equipment. The paragraphs below describe the editable parameters and their defaults. Table 3-42 explains how to edit the parameter settings.

S RfdsEquip – valid inputs are 0 through 2.

0 = (default) RFDS is not equipped 1 = Non-Cobra/Patzer box RFDS 2 = Cobra RFDS

NOTE

S TsuEquip – valid inputs are 0 or 1

0 = (default) TSU not equipped 1 = TSU is equipped in the system

S MC1....4 – valid inputs are 0 or 1

0 = (default) Not equipped 1 = Multicouplers equipped in RFDS system

(9600 system RFDS only)

S Asu1/2Equip – valid inputs are 0 or 1

0 = (default) Not equipped 1 = Equipped

S TestOrigDN – valid inputs are ’’’ (default) or a numerical string up to

15 characters. (This is the phone number the RFDS dials when originating a call. A dummy number needs to be set up by the switch, and is to be used in this field.)

Any text editor may be used to open the bts–#.cdf file to verify, view, or modify data. Because the bts–#.cdf file is generated on a Unix system, a more sophisticated editor, such as MicroSoft WordPad, will display file content in a more easily–read format than many simple text editors.

RFDS Set–up and Calibration

68P09258A31–A

RFDS Calibration

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 3-47.

5 Verify:

• The other PA module did not go OOS due to the loss of the PA.

• The overall carrier amplitude is reduced by approximately 6 dB and IM suppression on the analyzer

display remains basically unchanged.

• PA fault message is reported via the MGLI and displayed on the alarm monitor.

6 Re-apply power to the PA module and observe the alarm has cleared on the alarm monitor.

NOTE

All PWR/ALM LEDs should be GREEN at completion of test.

7 Repeat Steps 4 through 6 to verify the 2nd PA of the pair.

8 De-key the BBX.

n WARNING

First verify there are no BBX channels keyed when moving the antenna connection. Failure to do so can result in serious personal injury and/or equipment damage.

9 Repeat Steps 1 through 8 to verify PAs assigned to sectors 2 and 3 (if equipped). Move the test cable

on top of the BTS to TX OUT 2 and TX OUT 3 antenna connectors as required.

MGLI/GLI Redundancy Test

BTS Redundancy/Alarm Testing68P09258A31–A

CAUTION

Table 3-56: MGLI/GLI Redundancy Test (with MM Connection Established)

Step Action

This test can only be performed when the MM path is established by the MM (not just with LAPD link connected). Attempting to force the GLIs to “hot swap” under alarm monitor control, when isolated from the MM, causes MGLIs to hang up.

NOTE

S This test assumes the alarm monitor is NOT connected to the BTS and the T1/E1 span is connected

and communication is established with the MM.

S BOTH GLIs must be INS before continuing.

1 Verify the BBXs are enabled and a CDMA carrier is present.

2 Identify the primary and redundant MGLI pairs.

3 Pull the MGLI that is currently INS–ACT and has cage control.

4 Observe the BBX remains GREEN, and the redundant MGLI is now active.

5 Verify no other modules go OOS due to the transfer of control to the redundant module.

6 Verify that the BBXs are enabled and a CDMA carrier is present.

7 Reinstall the MGLI and have the OMCR/CBSC place it back in-service.

8 Repeat Steps 1 through 7 to verify the other MGLI/GLI board.

Alarms Testing

Alarm Verification

ALARM connectors provide Customer Defined Alarm Inputs and Outputs. The customer can connect BTS site alarm input sensors and output devices to the BTS, thus providing alarm reporting of active sensors as well controlling output devices.

The SC 4812T is capable of concurrently monitoring 36 input signals coming into the BTS. These inputs are divided between 2 Alarm

connectors marked ‘ALARM A’ and ‘ALARM B’ located at the top of the frame (see Figure 3-31). The ALARM A connector is always functional; ALARM B is functional when an AMR module is equipped in the AMR 2 slot in the distribution shelf. ALARM A port monitors input numbers 1 through 18, while ALARM B port monitors input numbers 19 through 36 (see Figure 3-32). State transitions on these input lines are reported to the LMF and OMCR as MGLI Input Relay alarms.

ALARM A and ALARM B connectors each provide 18 inputs and 8 outputs. If both A and B are functional, 36 inputs and 16 outputs are available. They may be configured as redundant. The configuration is set by the CBSC.

Alarm Reporting Display

The Alarm Monitor window can be displayed to list alarms that occur after the window is displayed. To access the Alarm Monitor window, select Util>Alarm Monitor.

The following buttons are included:

S The Options button allows for a severity level (Warning, Minor, and

Major) selection. The default is all levels. To change the level of

alarms reported click on the Options button and highlight the desired alarm level(s). To select multiple levels press the <Ctrl> key (for individual selections) or <Shift> key (for a range of selections) while clicking on the desired levels.

S The Pause button pauses/stops the display of alarms. When the Pause

button is clicked the name of the button changes to Continue. When the Continue button is clicked, the display of alarms continues. Alarms that occur between the time the Pause button is clicked and the Continue button is clicked are not displayed.

S The Clear button clears the Alarm Monitor display. New alarms that

occur after the Clear button is clicked are displayed.

S The Dismiss button dismisses/closes the Alarm Monitor display.
