General Safety

Remember! . . . Safety depends on you!!

Ground the instrument

The following general safety precautions must be observed during all phases of operation, service, and repair of the equipment described in this manual. Failure to comply with these precautions or with specific warnings elsewhere in this manual violates safety standards of design, manufacture, and intended use of the equipment. Motorola, Inc. assumes no liability for the customer’s failure to comply with these requirements. The safety precautions listed below represent warnings of certain dangers of which we are aware. You, as the user of this product, should follow these warnings and all other safety precautions necessary for the safe operation of the equipment in your operating environment.

To minimize shock hazard, the equipment chassis and enclosure must be connected to an electrical ground. If the equipment is supplied with a three-conductor ac power cable, the power cable must be either plugged into an approved three-contact electrical outlet or used with a three-contact to two-contact adapter. The three-contact to two-contact adapter must have the grounding wire (green) firmly connected to an electrical ground (safety ground) at the power outlet. The power jack and mating plug of the power cable must meet International Electrotechnical Commission (IEC) safety standards.

Do not operate in an explosive atmosphere

Keep away from live circuits

Do not service or adjust alone

Do not operate the equipment in the presence of flammable gases or fumes. Operation of any electrical equipment in such an environment constitutes a definite safety hazard.

Operating personnel must:

 not remove equipment covers. Only Factory Authorized Service

Personnel or other qualified maintenance personnel may remove equipment covers for internal subassembly, or component replacement, or any internal adjustment.

 not replace components with power cable connected. Under certain

conditions, dangerous voltages may exist even with the power cable removed.

 always disconnect power and discharge circuits before touching them.

Do not attempt internal service or adjustment, unless another person, capable of rendering first aid and resuscitation, is present.

Dangerous procedure warnings

Breakage of the Cathode–Ray Tube (CRT) causes a high-velocity scattering of glass fragments (implosion). To prevent CRT implosion, avoid rough handling or jarring of the equipment. The CRT should be handled only by qualified maintenance personnel, using approved safety mask and gloves.

Because of the danger of introducing additional hazards, do not install substitute parts or perform any unauthorized modification of equipment. Contact Motorola Warranty and Repair for service and repair to ensure that safety features are maintained.

Warnings, such as the example below, precede potentially dangerous procedures throughout this manual. Instructions contained in the warnings must be followed. You should also employ all other safety precautions that you deem necessary for the operation of the equipment in your operating environment.

WARNING

Dangerous voltages, capable of causing death, are present in this equipment. Use extreme caution when handling, testing, and adjusting.

CDMA LMF Product Description

CDMA LMF is a graphical user interface (GUI) based Local Maintenance Facility(LMF). This product is specifically designed to provide cellular communications field personnel the vehicle to support the following CDMA Base Transceiver Stations (BTS) operations:

 Installation  Maintenance  Calibration  Optimization

Online Help

Task oriented online help is available in the LMF by clicking on Help from the menu bar.

Why Optimize?

Proper optimization and calibration assures:

What Is Optimization?

 Accurate downlink RF power levels are transmitted from the site.  Accurate uplink signal strength determinations are made by the site.

Optimization compensates for the site-specific cabling and normal equipment variations. Cables that interconnect the BTS and Duplexer assemblies (if used), for example, are cut and installed at the time of the BTS frame installation at the site. Site optimization guarantees that the combined losses of the new cables and the gain/loss characteristics and built-in tolerances of each BTS frame do not accumulate, causing improper site operation.

Optimization identifies the accumulated loss (or gain) for all receive and transmit paths at the BTS site, and stores that value in a database.

 RX path starts at the ancillary equipment frame RFDS RX directional

coupler antenna feedline port, through the RX input port on the rear of the frame, through the DDRCs, Multicoupler Preselector Card (MPC), and additional splitter circuitry, ending at a Code Division Multiple Access (CDMA) Channel Processor (C–CCP) backplane Broad Band Transceiver (BBX2) slot in the C–CCP shelf.

 A transmit path starts at the BBX2, through the C–CCP backplane

slot, travels through the LPA/Combiner TX Filter and ends at the rear of the input/output (I/O) Panel. If the RFDS option is added, then the TX path continues and ends at the top of the RFDS TX directional coupler antenna feedline port installed in the ancillary equipment frame.

1-2

These values are factored in by the BTS equipment internally, leaving only site specific antenna feed line loss and antenna gain characteristics to be factored in by the CFE when determining site Effective Radiated Power (ERP) output power requirements.

SC 4812ET BTS Optimization/ATP – CDMA LMF

PRELIMINARY 2

July 1999

Optimization Overview – continued

Each C–CCP shelf BBX2 board is optimized to a specific RX and TX antenna port. (One BBX2 board acts in a redundant capacity for BBX2s 1–12, and is optimized to all antenna ports). A single value is generated for each path, thereby eliminating the accumulation of error that would occur from individually measuring and summing the gain and loss of each element in the path.

When to Optimize

New Installations

After the initial site installation, the BTS must be prepared for operation. This preparation includes verifying hardware installation, initial power up, and GPS verification. Basic alarm tests are also addressed.

A calibration audit of all RF transmit paths is performed to verify factory calibration.

A series of ATP CDMA verification tests are covered using the actual equipment set up. An Acceptance Test Procedure (ATP) is also required before the site can be placed in service.

Required Documents

Site Expansion

Optimization is also required after expansion of a site.

Periodic Optimization

Periodic optimization of a site may also be required, depending on the requirements of the overall system.

Repaired Sites

Verify repair(s) made to the BTS by consulting an Optimization/ATP Test Matrix table. This table outlines the specific tests that must be performed anytime a BTS subassembly or RF cable associated with it is replaced.

IMPORTANT

The following documents are required to perform optimization of the cell site equipment:

Optimization Overview – continued

Test Equipment Calibration

Optimum system performance and capacity depend on regular equipment service, calibration, and characterization prior to BTS optimization. Follow the original equipment manufacturer (OEM) recommended maintenance and calibration schedules closely.

Test Cable Calibration

Equipment test cables are very important in optimization. Motorola recommends that the cable calibration be run at every BTS with the test cables attached. This method compensates for test cable insertion loss within the test equipment itself. No other allowance for test cable insertion loss needs to be made during the performance of tests.

Another method is to account for the loss by entering it into the LMF during the optimization procedure. This method requires accurate test cable characterization in a shop. The cable should be tagged with the characterization information prior to field optimization.

Equipment Warm–up

Test Equipment List

After arriving at the a site, the test equipment should be plugged in and turned on to allow warm up and stabilization to occur for as long as possible. The following pieces of test equipment must be warmed–up for a minimum of 60 minutes prior to using for BTS optimization or Radio Frequency Diagnostic Subsystem (RFDS) calibration procedures.

 Communications Test Set  Rubidium Time Base  Power Meter

The following pieces of test equipment are required during the optimization procedure. Common assorted tools like screwdrivers and frame keys are not listed but are still required. Read the owner’s manual on all of the following major pieces of test equipment to understand their individual operation prior to use in optimization.

BTS Frame Identification

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

 The I/O interconnect plate where all connections are made is located at

the back of the BTS.

 The RF section of the frame which houses the circuit breakers, cooling

fans, the Combined CDMA Channel Processor (C–CCP) shelf, the duplexors, filters, RFDS and CSU.

 The LPA compartment which houses the LPAs and blower assembly.

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

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

Site Equipage Verification

This section first verifies proper frame equipage. This includes verifying module placement, jumper, and dual in–line package (DIP) switch settings against the site-specific documentation supplied for each BTS application. Next, pre-power up and initial power-up procedures are presented.

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

The Cell-site Data File (CDF) contains site type and equipage data information and passes it directly to the LMF during optimization. The number of modem frames, C–CCP shelves, BBX2 and MCC24/MCC8E boards (per cage), and linear power amplifier assignments are some of the equipage data included in the CDF.

Review the site documentation. Match the site engineering equipage data to the actual boards and modules shipped to the site. Physically inspect and verify the equipment provided for the BTS or Modem frame and ancillary equipment frame.

CAUTION

Always wear a conductive, high impedance wrist strap while handling any circuit card/module to prevent damage by ESD. After removal, the card/module should be placed on a conductive surface or back into the anti–static bag it was shipped in.

Initial Installation of Boards/Modules

Table 2-1: Initial Installation of Boards/Modules

Step Action

1 Refer to the site documentation and install all boards and modules into the appropriate shelves as

required. Verify they are NOT SEATED at this time.

2 As the actual site hardware is installed, record the serial number of each module on a “Serial Number

Checklist” in the site logbook.

Power Cabinet Initial Power Up

Introduction

Required Tools

Initial Inspection and Setup

This section of the manual contains instructional information on the proper power up procedure for the SC 4812ET BTS. Also presented in this chapter is the Optimization/ATP 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 Power Cabinet Power Up procedures.

 Digital Voltmeter  DC current clamp (600 Amp capability with jaw size to accommodate

2/0 cable).

 Hot Air Gun – (optional for part of the Alarm Verification)

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.

Verify that ALL AC and DC breakers are turned OFF in the Power cabinet. Verify all DC circuit breakers are OFF in the RF cabinet. Verify that the DC power cables between the Power and RF cabinets are connected with the correct polarity

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.

CAUTION

Failure to connect the proper AC feed will damage the surge protection module inside the AC load center.

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 2-2: 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).

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

nominally 115 to 120 V AC.

Power Cabinet Initial Power Up – continued

Table 2-2: AC Voltage Measurements

Step Action

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.

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.

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.

Turn Rectifier 1 and Rectifier 2 AC branch breakers (on the AC Load Center) ON. All the installed rectifier modules will start up and should each have two green LEDs (DC and Power) illuminated.

Turn the DMAC (Digital Metering and Alarms Control) module, ON while observing the K2 contact in the PDA assembly. The contact should close. The DMAC voltage meter should read approximately 27.4 + VDC.

Turn the TCP (Temperature Control Panel) ON, .The DMAC should not be have any alarm LEDs illuminated .

Check the rectifier current bargraph displays. 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.

Power Up Tests

Table 2-3 lists the step–by–step instructions for Power Up Tests.

Table 2-3: Power Up Tests

Step Action

1 Probe the output voltage test point on the DMAC while pressing the 25° C set button on the TCP.

The voltage should read 27.4 + 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 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.

4 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.

0.2 VDC. Adjust Master Voltage on DMAC if necessary. Release

5 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.

Battery Charge Test

Table 2-4 lists the step–by–step instructions for testing the batteries.

Table 2-4: Battery Charge Test

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

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 DMAC power switch, and then engage all the connected battery circuit breakers, the DMAC 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 amps).

PRELIMINARY 2

Power Cabinet Initial Power Up – continued

Table 2-4: Battery Charge Test

Step Action

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 Amps) of the rectifiers maximum (70 Amps) 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 Amps, therefore, 3 X 8.75 equals

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

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 5A.

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.

RF Cabinet Power Up

Table 2-5 covers the procedures for properly powering up the RF Cabinet.

Table 2-5: RF Cabinet Power Up

Step Action

1 Turn the 400 Amp Main DC breaker in the RF Cabinet ON.

NOTE

Ensure that no alarms or voltage change has occurred in the power cabinet, and that the power cabinet Main DC breakers have not tripped. The rectifier bargraph readings should be the same as

before the main breaker in the RF cabinet was turned ON. 2 Proceed to RF cabinet power up sequence. 3 The RF Cabinet ATP procedure can now proceed in parallel with the remaining Power Supply

Cabinet tests.

Table 2-5: RF Cabinet Power Up

Step Action

4 Measure the voltage drop between the Power Cabinet meter test point and the 27 V buss bar inside

the RF Cabinet PDA while the RF Cabinet is transmitting.

NOTE

For a three (3) sector carrier system, the voltage drop should be less than 0.2 VDC.

For a twelve (12) sector carrier system, the voltage drop should be less than 0.3 VDC. 5 Using a DC current probe, measure the current in each of the six (6) DC cables that are connected

between the RF and Power Cabinet. The DC current measured should be approximately the same.

If there is a wide variation between one cable and the others (>10 A), check the tightness of the

connections (torque settings) at each end of the cable.

Battery Discharge Test

The test procedures in Table 2-6 should only be performed when the battery current is less than 5 A per string. Refer to Table 2-4 on the procedures for checking current levels.

Alarm Verification

The alarms test should be performed at a convenient point in the RF

Alarm Reporting Display

Cabinet ATP procedure, since an LMF is necessary to ensure that the RF Cabinet is receiving the appropriate alarms from the Power Cabinet.

The SC 4812ET is capable of concurrently monitoring 10 customer defined input signals and four customer defined outputs, which interface to the 50–pin punchblock. All alarms are defaulted to “Not Equipped” during ATP testing. Testing of these inputs is achieved by triggering the alarms and monitoring the LMF for state–transition messages from the active MGLI2.

All customer alarms are routed through the 50 pair punchblock located in the I/O compartment at the back of the frame. Testing is best accomplished by using a specialized connector that interfaces to the 50–pair punchblock. This connector is wired so that customer return 1 (2 for the B side) is connected to every input, CDI 0 through CDI 17.

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.

 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.

 The Pause button can be used to pause/stop the display of alarms.

When the Pause button is clicked the name of the button changes to Continue. When the Continue button is click the display of alarms

will continue. Alarms that occur between the time the Pause button is clicked and the Continue button is clicked will not be displayed.

 The Clear button can be used to clear the Alarm Monitor display.

New alarms that occur after the Clear button is clicked will be displayed.

 The Dismiss button is used to dismiss/close the Alarm Monitor

display.

DC Power Pre-test (BTS Frame)

Before applying any power to the BTS cabinet, follow the steps outlined in Table 2-18 while referring to Figure 2-2 to verify there are no shorts in the RF or Power Cabinet’s DC distribution system.

Table 2-18: DC Power Pre–test (RF Cabinet and Power Cabinet)

Step Action

1 Physically verify that all DC/DC converters supplying power to the cabinets are OFF or disabled. 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).

Optimization/Calibration – Introduction

Introduction

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

Cell–site Types

Cell–site Data File (CDF)

Sites are configured as Omni/Omni or Sector/Sector (TX/RX). Each type has unique characteristics and must be optimized accordingly.

NOTE

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

Installation and Functional Hardware Description

manuals.

The CDF includes the following information:

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

– BBX2 equipage (based on cell–site type) including redundancy – CSM equipage including redundancy – Multi Channel Card 24 (MCC24 or MCC8E) channel element

allocation plan. This plan indicates how the C–CCP shelf is configured, and how the paging, synchronization, traffic, and access channel elements (and associated gain values) are assigned among the (up to 12) MCC24s or MCC8Es in the shelf.

July 1999

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

BTS System Software Download

BTS system software must be successfully downloaded to the BTS processor boards before optimization can be performed. BTS operating code is loaded from the LMF computer terminal. Before you can log into a site, the LMF must have a BTS folder for that site. Whenever there is a new release of BTS system software (binaries), it must first be loaded on the LMF from a CD–ROM before it can be downloaded to the

Site Equipage Verification

BTS. The CDF is normally obtained from the CBSC on a floppy disk or through a file transfer protocol (ftp) if the LMF computer has the capability.

If you have not already done so, use an LMF to view the CDF, and review the site documentation. Verify the site engineering equipage data in the CDF to the actual site hardware.

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.

Alarm and Span Line Cable Pin/Signal Information

Channel Service Unit

Each frame is equipped with one 50 pair punchblock for spans, customer alarms, remote GPS, and power cabinet alarms (see Figure 3-1 and Table 3-1). To disable the span, pull out 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.

Table 3-1 lists the complete pin/signal identification for the 50–pin punch block.

The channel service unit (CSU) contains a modular Eternet jack on its fron panel, allowing Eternet UP access to CSUs installed in the same shelf Each 19 inch rack can support two CSU (M–PATH 538) modules. Each module supports one span connection. Programming of the CSU is accomplished through the DCE 9–pin connector on the front panel.

– 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!

Graphical User Interface Overview

This section provides overview information on using the LMF graphical user interface (GUI). The GUI works as follows:

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

taking place and other status information.

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

along with other pertinent information displayed.

 Clicking the OK button closes the status report window.

The R9 BTS software release implements the virtual BTS capability, also known as Logical BTS. A virtual BTS can consist of up to four four SC 4812ET frames. When the LMF is connected to frame 1 of a virtual BTS, you can access all devices in all of the frames that make up the virtual BTS A virtual BTS CDF file that includes equippage information for all of the virtual BTS frames and their devices is required. A CBSC file that includes channel data for all of the virtual BTS fames is also required. The first frame of a virtual BTS has a –1 suffix (e.g., BTS–812–1) and other frames of the virtual BTS are numbered with suffixed, –101, –201, and –301 (e. g. BTS–812–201). When you log into a BTS a FRAME tab is displayed for each frame. If there is only one frame for the BTS, there will only be one tab (e.g., FRAME–282–1) for BTS–282. If a virtual BTS has more than one frame, there will be a separate FRAME tab for each frame (e.g.

FRAME–438–1, FRAME–438–101, and FRAME–438–202 for a BTS–438 that has all three frames). If an RFDS is included in the CDF

file, an RFDS tab (e.g., RFDS–438–1) will be displayed.

Actions (e.g., ATP tests) can be initiated for selected devices in one or more, frames of a virtual BTS. Refer to the Select devices help screen for information on how to select devices.

Following are visual examples of the BTS tabs for a single–frame BTS with RFDS and a four–frame BTS with RFDS.

Enable CSMs

Each BTS CSM system features two CSM boards per site. 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 Low Frequency Receiver (LFR), 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 3-18 to enable the CSMs installed in the C–CCP shelves.

– Each CSM (of a redundant pair at each BTS) is

associated with “partner” MCCs. CSMs must be enabled before the partner MCC can be enabled.

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

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

– Verify the CSM configured with the GPS receiver

“daughter board” is installed in the frame’s CSM 1 slot before continuing.

From the Device pull down, select Enable.

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).

* 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).

NOTE

If equipped with two CSMs, CSM–1 should be bright green (INS–ACT) and CSM–2 should be

dark green(INS–STB)

If more than an hour has passed, refer to CSM Verification, see Figure 3-20 and Table 3-21 to

determine the cause.

NOTE

After the CSMs have been successfully enabled, observe the PWR/ALM LEDs are steady green

(alternating green/red indicates the card is in an alarm state).

CSM System Time – GPS & HSO Verification

CSM & LFR Background

The primary function of the Clock Synchronization Manager (CSM) boards (1 & 2) is to maintain CDMA System Time. The master GLI can request and distribute system time to the appropriate modules within a C–CCP shelf. The redundant GLI (slave) obtains system time from the master GLI over the LAN. All boards are mounted in the C–CCP shelf.

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 CSM 1 and 2 boards in the event of a GPS receiver failure on CSM 1 or a reference oscillator failure on either CSM board. During normal operation, the CSM 1 board oscillator output is selected as the source. The source selection can also be overridden via the LMF or by the GLI card.

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

(Stby).

 Flashing Green / Rapidly Flashing Red – CSM OOS–RAM

attempting to lock on GPS signal.

 Rapidly Flashing Green / Red – Alarm condition exists. Trouble

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

High Stability Oscillator (HSO)

The High Stability Oscillator (HSO) module is a separate full–size card which resides in a dedicated slot in the lower half of the C–CCP shelf. This is a completely self contained high stability 10 MHz oscillator which interfaces with the CSM via a serial communications link. The CSM handles the overall configuration and status monitoring functions of the HSO. In the event of GPS failure, the HSO is capable of maintaining synchronization initially established by the GPS reference

signal for a limited time The HSO is basically 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 and provides the following major functions:

 Reference oscillator temperature and phase lock monitor circuitry  Internal oscillator generates highly stable 10 MHz sine wave, and

routed to reference divider circuitry

 Reference divider circuitry converts 10 MHz sine wave to 10 MHz

TTL signal, which is divided to provide a 1 PPS strobe to the CSM

Equipment Warm–up

CSM frequency verification

Allow the base site and test equipment to warm up for 60 minutes after any interruption in oscillator power. CSM board warm-up allows the oscillator oven temperature and oscillator frequency to stabilize prior to test. Test equipment warm-up allows the Rubidium standard timebase to stabilize in frequency before any measurements are made.

The objective of this procedure is the initial verification of the Clock Synchronization Module (CSM) boards prior to performing the rf path verification tests. Parts of this procedure will be repeated for final verification after the overall optimization has been completed.

Step Action

7 If steps 1 through 6 pass, the GPS is good.

* IMPORTANT

If any of the above mentioned areas fail, verify that:

– If Initial position accuracy is “estimated”

visible (1 satellite must be tracked and visible if actual lat, log, and height data for this site has been entered into CDF file).

– If Initial position accuracy is “surveyed,”

accurate. GPS will not automatically survey and update its position. – The GPS antenna is not obstructed or misaligned. – GPS antenna connector center conductor measureS approximately +5 Vdc with respect to the

shield. – There is no more than 4.5 dB of loss between the GPS antenna OSX connector and the BTS frame

GPS input. – Any lightning protection installed between GPS antenna and BTS frame is installed correctly.

(typical), at least 4 satellites must be tracked and

position data currently in the CDF file is assumed to be

8 Enter the following commands at the CSM> prompt to verify that the CSM is warmed up and that GPS

acquisition has taken place.

debug dpllp

Observe the following typical response if the CSM is not warmed up (15 minutes from application of power) (If warmed–up proceed to step 9)

CSM>DPLL Task Wait. 884 seconds left. DPLL Task Wait. 882 seconds left.

DPLL Task Wait. 880 seconds left. ...........etc.

NOTE

The warm command can be issued at the MMI port used to force the CSM into warm–up, but the reference oscillator will be unstable.
