1-1Wireless Solutions TDMA 1900 Macrocell Cell Site Maintenance Manual MTX081General maintenance proceduresGeneral precautionsThere are some general precautions to be aware of when preforming maintenance on cell site components. When performing maintenance functions, take care not to do anything which would inadvertently take the site off the air (make the site drop phone calls in progress). The technician should always have a clear idea of the action being undertaken, and what is the potential impact and safety implications of the action on the operating condition of the network.RF radiation hazardRadio Frequency (RF) radiation can be hazardous to anyone working in the cell site. Before removing any RF cable, ensure that the transmitters are turned off. All RF cables should be connected properly and all unused RF ports should be terminated with an appropriate terminator. Cable/connector identificationLabel all cables and connectors before disconnecting them from any cell site equipment. This will minimize the time required for tracing the connections and also reduce the possibility of incorrect connections.Electrostatic Discharge (ESD)When handling any circuit board, take care to prevent damage from static discharge. Observe the following rules:1. To prevent electrostatic discharge, do not attach ribbon cables to circuit boards until the circuit boards are in place.2. To dissipate any static charge, wear a wrist strap in contact with the skin.3. Connect the wrist strap ground cord to the equipment cabinet ground.CautionRadiation HazardDo NOT disconnect any RF cables when transmitters are on.
1-2 General maintenance procedures411-6201-500 Preliminary 03.03 July 1999 ElectroStatic Discharge (ESD) controlThis section provides general guidelines and precautions for handling, transporting and storing components and printed circuit boards that are susceptible to permanent damage when subjected to electrostatic discharge (ESD).ESD sensitive equipmentVarious electrical and electronic components are vulnerable to ESD. These include:• discrete components• hybrid devices• Integrated Circuits (ICs)• circuit boards assembled with these devicesIdentificationManufacturers vary in their methods of identifying static-sensitive equipment. They may apply stickers or mark components with various colors, but many do not indicate that their products are sensitive. Examples of identification are:• Circuit boards with ESD-sensitive devices may have a red edge.• Hybrids containing Metal-Oxide Semiconductors (MOS) devices are red, with the letters MOS on the back. Non-sensitive hybrids are white.• Pull-handles on circuit packs containing sensitive devices may have the letters MOS and the assembly part number printed in red.• Assembly drawings may have manufacturing notes describing the circuits as ESD-sensitive.CautionEquipment DamageDo not let the circuit board come into contact with clothing at any time, as the grounding strap cannot dissipate static charges on fabrics.Equipment damageElectrostatic dischargeWhen in doubt, any circuit board containing microelectronic components must be assumed to be vulnerable to ESD.
General maintenance procedures 1-3Wireless Solutions TDMA 1900 Macrocell Cell Site Maintenance Manual MTX08Static control materials and devicesUse conductive bags and containers to store and transport circuit boards or components. There are three common types of conductive bags: Velostat, Tyvek and Pink Polyethylene.Note: Pink Polyethylene is not recommended for ESD control. Static-free work stationsStatic-sensitive devices must be removed from packages only at a static-free work area. The minimum equipment for a static-free work station is• conductive bench mat• operator's conductive wrist strapIdeally however, locations should be equipped as follows when necessary• wrist strap• shoe grounding straps• ionized air blower (where required)• ground cord• floor mats•table matsWhere protective measures have not been installed, a suitable alternative would be the use of a Portable Field Service Grounding Kit (3M part number 8012). This consists of a portable mat and wrist strap. The mat has pockets to hold circuit boards.Handling proceduresDegradation may occur at any time during the handling of electrostatic-discharge-sensitive devices and components. Boards or components should never come in contact with clothing, because normal grounding cannot dissipate the static charges on fabrics.Before handling static-sensitive equipment, personnel must discharge themselves of any static charge. The most effective method is the use of a grounded wrist strap combined with correctly installed ground static control Electric shock hazardMetalized or carbon bags are conductive and therefore must not contact live electrical circuits, or they may cause shorting, sparking, and shock hazards to personnel.
1-4 General maintenance procedures411-6201-500 Preliminary 03.03 July 1999mats at all work locations. The wrist strap must be permanently attached to the frame on the basis of one between two frames. Alternatively the straps may be connected on an as-required basis to the battery return (ground) jack, where it is provided.HandlingElectrostatic-discharge-sensitive devices must be handled only in static-free locations. These locations must be equipped with grounded table and floor mats and grounded wrist straps. Also a reasonable relative humidity (RH) level must be maintained, if economically feasible, of between 20% and 80% non-condensing. In places where humidification is not practical, the other static control measures must be carefully observed.Electrostatic-discharge-sensitive equipment must be handled only after personnel have grounded themselves with wrist straps, or shoe straps and mats.No electrostatic-discharge-sensitive device should be removed from its protective package, except in a static-free location. The recommended packaging is a form of Faraday cage that will protect the contents against any charge present under normal conditions. Damaged packaging must be replaced at once.All common plastics and other prime generators (e.g. nylon carpet, plastic mats) must be prohibited in the electrostatic-discharge-free area.Use only static-shielding packing material.TransportingA circuit pack must be placed into an anti-static shielding bag before being removed from the work location and must remain in the bag until it arrives at a static-free repair/test center.Where handles or finger holes are provided on circuit packs they must be used to remove and replace the boards, and care taken to avoid contact with the connectors and components.Equipment damageElectrostatic dischargeAt no time must an unprotected circuit board come in contact with clothing, plastics, or ungrounded personnel
General maintenance procedures 1-5Wireless Solutions TDMA 1900 Macrocell Cell Site Maintenance Manual MTX08StorageImproper storage can cause failures in ESD-sensitive components. The guidelines for environmental factors (temperature, moisture, air pollutants) are as important during storage as they are for operating. Wider variations of temperature may be allowable, depending on the type of device. In general, low temperatures do not damage inactive equipment provided that the device is slowly raised to normal room temperature before use.Electrostatic discharge damage to unprotected sensitive devices may occur at any time. Therefore it is important to keep ESD-sensitive circuit boards and components in proper protective packages during storage. Discard suspect bags and use new ones. Whenever possible, units requiring protection should be identified on the protective packing.Note: A circuit board in a static shielding bag may be shipped or stored in a cardboard carton, but the carton must not enter a static-free area such as a bench top or repair zone.For more information on ESD and its control, refer to the following documents:• Test Methods for Static Control Products (Huntsman & Yenni, 3M Company)• Protection and Handling of ESD-Sensitive Circuit Packs (Bell Canada, BCP069-8000-501)
1-6 General maintenance procedures411-6201-500 Preliminary 03.03 July 1999Field Replaceable Units (FRU’s)The components of a TDMA 1900 Macrocell are not designed to be repaired in the field. The only maintenance that can be performed is to replace the components or the Field Replaceable Units (FRU). See Table 1-1, “Major components of a TDMA 1900 Macrocell cell site,” on page 1-8 for FRU list and description.Note: Refer to TDMA 1900 Macrocell Troubleshooting Guide, 411-6201-501 to determine if a component needs to be replaced. Replacing faulty units in the Common Equipment (CE) frame For the replacement of a unit on the CE frame, use the following procedure:1. From a MAP terminal put the cell site or the unit out-of-service as required.2. If replacing the Rack Interface Panel (RIP), switch off the supply to the frame at the power plant.If replacing other units, switch off both the ‘A’ and ‘B’ circuit breakers to that unit at the RIP.3. Label and disconnect the cables/connectors connected to the unit.4. Remove the screws mounting the unit to the frame and then remove the unit from the frame.5. Replace a new or known working unit on to the frame and secure it with the mounting screws.6. Reconnect the cables/connectors to their appropriate locations. Ensure that they are properly connected.7. Switch on the circuit breakers to the unit at the RIP or switch on the power supply to the frame at the power plant.8. From the MAP, ensure that the datafill information on the replacement unit is correct, if applicable.9. From the MAP, return the cell site back into service.10. Verify that the replacement unit is functioning correctly.CautionService AffectingA cell site may be completely out-of-service when a unit such as the RIP, VSMO, RPDU, splitters or the ICRM is removed. Replacing these units should only take place during non-busy hours.
General maintenance procedures 1-7Wireless Solutions TDMA 1900 Macrocell Cell Site Maintenance Manual MTX0811. Tag and return the faulty unit to your Nortel Customer Service Operations office for repair.Replacing faulty units in the Radio Frequency (RF) frameFor the replacement of a unit on the RF frame, use the following procedure:1. Put the cell site or the unit out-of-service as required.2. If replacing the Rack Interface Panel (RIP), switch off the supply to the RF frame at the power plant.3. If replacing other units, switch off both the ‘A’ and ‘B’ circuit breakers to that unit at the RIP.4. Label and disconnect the cables/connectors connected to the unit.5. Remove the screws mounting the unit to the frame and then remove the unit from the frame.6. Replace a new or known working unit into the frame and secure it with the mounting screws.7. Reconnect the cables/connectors to their appropriate locations. Ensure that they are properly connected.8. Switch on the circuit breakers to the unit at the RIP or switch on the power supply to the RF frame at the power plant.9. Ensure that the datafill information on the replacement unit is correct.10. Put the cell site back into service.11. Verify that the replacement unit is functioning correctly.12. Tag and return the faulty unit to your Nortel Customer Service Operations office for repair.Latching mechanismThe module latching mechanism is mounted to the shelf with the pickup on the radio and SCLPA module. The cam-style lock latch is used to prevent “slamming” of the module into place, and allows consistent seating of the connector.CautionService AffectingA cell site may be completely out-of-service when a unit such as the RIP, the Duplexer, or the ATC is removed. Replacing these units should only take place during non-busy hours.
1-8 General maintenance procedures411-6201-500 Preliminary 03.03 July 1999ReplacementThe latch module can be replaced if required. If a latch on the PA breaks, the PA shelf needs to be pulled out of the frame, then the latch module can be removed and a new one installed. The latch module fastens to the top of the shelf with three screws. If a latch on the TRU shelf breaks, then the PA shelf directly above the TRU shelf should be removed, and the TRU shelf latch module can be replaced while the shelf is still in the frame. This is done because there is much less interconnect on the PA shelf, and it is easier to remove then the TRU shelf.Product structure for a TDMA 1900 Macrocell cell siteThe product structure is a list of components for the TDMA 1900 Macrocell cell site.

2-1Wireless Solutions TDMA 1900 Macrocell Cell Site Maintenance Manual MTX082Test equipmentThe TDMA 1900 Macrocell is operated by the Digital Multiplex Switch - Mobile Telephone Exchange (DMS-MTX). It can also be operated by service personnel at the cell site through an interface terminal to perform some operational functions and tests. This section provides information on how to operate the cell site equipment and perform maintenance tasks and operational tests at the cell site. However, some of the tests may involve activities at the MTX. For details of the MTX activities, refer to the appropriate DMS-MTX manuals.To operate and test cell site equipment, an interface terminal and other test equipment is required. This chapter provides a list of recommended test equipment and precautions to be aware of when performing any tasks at the cell site.Precautions Equipment warm-upDo not perform tests immediately after the installation of any equipment. The cell site and the test equipment should be powered up for at least half an hour before testing. Inaccurate measurements may result if the warm-up period is less than 30 minutes.Test equipment calibrationProper setup of the test equipment is critical in obtaining proper test results. Consistency of setup and techniques from one person to another is essential for obtaining proper system operation. Calibrate all test equipment before use.Equipment damageEnsure that the test equipment maximum allowable input levels are not exceeded. Add an attenuator to reduce the power if necessary.
2-2 Test equipment411-6201-500 Preliminary 03.03 July 1999RF radiation hazardRadio Frequency (RF) radiation is hazardous to anyone working in the cell site. All RF cables should be connected properly and all unused RF ports should be terminated with an appropriate terminator. Test equipmentIt is assumed that the operator is familiar with the test equipment used in the test procedures. The following test equipment is recommended for performing the required tests. Any functionally equivalent unit may be used in its place. Double shielded coaxial cables are recommended for use between test equipment and the equipment being tested.Note: Ensure test equipment is calibrated before performing any tests.1.

VSWR bridgeTerminal interface operationIntroductionThe TRU supports an Interface Terminal (VT100 or equivalent) which allows local direct control for monitoring, maintenance, and control purposes. Connect the terminal to the RS-232 interface port on the front panel of the TRU while the TRU is in either “Active” or “Debug” mode. Commands are used to set operating parameters, and perform control, test, maintenance and status query functions. The TRU need not be connected to the rest of the Digital Multiplex System-Mobile Telephone Exchange (DMS-MTX) system. The terminal interface can be operated in these modes:• Command Line mode. This mode allows for maintenance, measurement, and test commands to be executed.or• Fullscreen Monitor mode. This mode groups the commands used for commissioning a cell site together into a single screen.TRU to Terminal Interface connectionUse one of the cables with the pinouts as indicated in Table 2-1 to connect the TRU (RJ45 Teledapt connector on the front panel of the TRU) to the Terminal Interface.

A “>” prompt will be printed on the screen indicating that the terminal is “communicating” with the TRU.Information required can be obtained by using the QUERY commands which can be displayed by typing “HELP MSR”.On-line help Using the Fullscreen Monitor is simplified by an on-line help system. To access it, type “HELP” or “?” in response to any prompt. A brief description of the TRU terminal interface is displayed. Several on-line help categories are available. Each category contains a one-line description of each command in that category. The following categories of help commands are available:• HELP HELP - Lists help categories• HELP MTCE - Lists maintenance commands• HELP TESTS - Lists test commands• HELP MSR - List measurement and query commands• HELP MONITOR - List commands within the monitor subsystemInterfacing the TRU while it is Off-line or ManbusyWith the a terminal connected you can access the command line mode by pressing the “Break” key on the terminal keyboard. The terminal will display:For the TRU 1900:TRU Terminal Interface(C) Copyright 1990,1996 Bell Northern Research, Inc.>For the TRUIII 1900:TRU-III Terminal Interface(C) Copyright 1996-97 Nortel>At this point, there is about ten seconds before the TRU times-out and returns to ROM IDLE. Before the ten seconds has elapsed, the Lap Timer must be disabled, by typing:>SET LT OFFThe Terminal Interface is now in the Command Line mode and ready to receive commands. Please refer to Table 2-8, Table 2-9 and Table 2-10 for Command Line Mode commands.
2-6 Test equipment411-6201-500 Preliminary 03.03 July 1999Disconnecting the Terminal InterfaceOnce the terminal session is completed, terminate the communication with the following commands:Fullscreen Mode: Use the Y command which initiates a restart and will disconnect the communications.Command Line Mode: Use EXECUTE RESTARTFLASH command to disconnect the communications.Note: Avoid removing the TRU from its transceiver shelf slot for the purpose of executing a restartflash. If the TRU is detached from its transceiver shelf backplane connection and then re-connected, it may require some commissioning to ensure that all RF connections are established correctly. Re-insertion of the TRUs to the backplane cause wear and tear on the gold-plated backplane pins and may reduce connectivity and increase path loss.Remote Radio InterFace (RRIF)The RRIF is a software feature introduced with MTX04. It allows remote OAM access to cell site DRU’s from a MAP based terminal. Refer to NTP 411-2131-115 Remote Radio InterFace Reference.Entering the Fullscreen modeThe primary purpose of the Fullscreen Monitor is to provide a means for quickly commissioning a TRU in a cell site. It provides a more user-friendly access to the TRU’s OAM test and maintenance functions than the command line mode. Note: The Fullscreen Monitor is intended for use on a TRU which is not in an active call processing state. The TRU must be at ROM idle (indicated on the front panel display) to operate in the Fullscreen Monitor mode. The Fullscreen Monitor is capable of two modes of operation, analog (AMPS) and digital (TDMA) and has the ability to switch between either one.Note: Although the AMPS (Advanced Mobile Phone System) personalities (ACC (Analog Control Channel), AVC (Analog Voice Channel), and ALR (Analog Locate Receiver)) are not valid operating modes, the terminal interface software does not block any attempts to set the TRU 1900 to these personalities. However, the AMPS personalities or any related terminal interface commands are not guaranteed for valid operation.To enter the Fullscreen mode, at the command line prompt (>) type in the following command:

To get to TDMA mode select ‘A’, then return.In the Fullscreen mode, the OAM commands are displayed and selected by their alphabetic code. The results of each OAM command are displayed at specific screen locations. Figure 2-2 shows the Fullscreen display for TRUs in the TDMA mode.The Fullscreen display is divided horizontally into a status area and a command area. The bottom line of the display is used as the “command prompt” area; you may enter the appropriate command letter here. Directly above the command area is the output message line where status and output messages, such as selection parameters and error messages, are displayed.

3-1Wireless Solutions TDMA 1900 Macrocell Cell Site Maintenance Manual MTX083Maintenance schedulesThis section provides the maintenance reference chart and the corresponding periodic check lists, and when necessary, refers to detailed process procedures in this manual.Periodic maintenance recordsPeriodic maintenance allows for• the detection and replacement of degraded equipment before it affects service• preventative steps to protect equipment from damage or degradationTo support these functions, records must be kept. Records allow you to• recognize deteriorating performance by comparing current and past test results• ensure that all steps required to protect equipment have been taken• create a maintenance history of a cell site; thereby allowing you to plan for the future and predict future maintenance needs• provide information to decide sparing levels and "out of expectation" failure level for specific equipmentManuals and recordsFor maximum benefit, manuals, site logs, and maintenance records should be organized, kept on site and readily accessible so that call-out staff have access to and can determine the maintenance history of a particular site. All records should be completed before leaving the site.Schedule for periodic cell site maintenance Regularly scheduled visits are important for the preventative maintenance of a cell site. However, if maintenance teams are responsible for a number of cell sites, maintenance schedules for the different sites should be staggered so that labour time is more effectively and efficiently managed. Table 3-1 is an example of a maintenance schedule for six cell sites where the periodic routines are distributed evenly throughout a one year period.

5-1Wireless Solutions TDMA 1900 Macrocell Cell Site Maintenance Manual MTX085Very Stable Master Oscillator (VSMO) testsVery Stable Master Oscillator (VSMO)Cell site transceivers require a stable reference in order to accurately produce transmit carrier frequencies and to select receive frequencies. The VSMO produces this stable reference for the Transmit Receive Units (TRUs) to ensure that all channels operate on their assigned frequencies and do not interfere with other channels. Therefore the VSMO should be tested once each year.Master Oscillator power and frequency testFollow the steps in Table 5-1 for the oscillator test procedures. See Figure 5-1 and Table 5-2 for IFR test set up. AttentionMeasurement discrepancyWhen using the Power Meter on the IFR 1900, the signal reading was 5.8–6.3 dB lower than the Spectrum Analyzer value.Table 5-1VSMO test proceduresStep Action Observation1Connect the communications monitor to the output port on the back of the VSMO.

6-1Wireless Solutions TDMA 1900 Macrocell Cell Site Maintenance Manual MTX086Antenna and Transmission line testsAntenna direct current continuityThese tests are required for new antennas or antennas suspected of faulty operation. These tests are service affecting.The most important consideration of antenna direct current continuity is not so much the antenna but the transmission line shield. Of course, the antenna must be electrically connected to the coaxial transmission line, but most important, the transmission line shield must be grounded for lightning protection.The other dc tests serve as more of a record of the resistance of the shield and center conductor. They may indicate future grounding problems or identify a change in the antenna dipole condition (open, now shorted or vice versa). Follow Table 6-1 for the antenna direct current continuity test.CAUTIONRF Radiation HazardAll transceiver transmitters must be turned off before disconnecting or connecting transmit cables to avoid RF induced injuries.CAUTIONService DisruptionThe following tests are service affecting when the antenna is disconnected.
6-2 Antenna and Transmission line tests411-6201-500 Preliminary 03.03 July 1999Table 6-1Direct current continuity testAntenna return lossThe antenna return loss is measured to verify that the antenna is properly matched to the system and to identify open connectors. This test uses the signal generator, the spectrum analyzer and the VSWR bridge to sweep the antenna for return loss at both the receive (1850 to 1910 MHz) and transmit (1930 to 1990 MHz) frequency bands.Test equipment: RF Signal GeneratorSpectrum AnalyzerVSWR BridgeIf any of the test equipment is not available, a Thruline Wattmeter may be used.Refer to Figure 6-1 and Table 6-2 for antenna return loss test set up diagram and test procedure.Step Action Observation1Visually inspect the bonding of the transmission line to the mast ground riser at both the top and bottom of the tower.The transmission line must be bonded at both the top and bottom. A set of binoculars or a spotting telescope may be required to verify the upper bonding.2Inside the building, measure the dc resistance of the outer conductor to the principle ground.Less than or equal to 0.5 Ω3Measure and record the dc resistance of the center conductor (pin) to the outer conductor (shield).4Also check the alignment of the center pin of the heliax connector. If necessary re-align the centre pin so that the female pin in the antenna jumper cable connector is not damaged.Repair or replace heliax, connectors, ground systems as required.CAUTIONService DisruptionThe following tests are service affecting when the antenna is disconnected.

7-1Wireless Solutions TDMA 1900 Macrocell Cell Site Maintenance Manual MTX087Tx insertion loss testOverviewCheck the transmit insertion loss once a year. The AutoTune Combiners (ATC) require no periodic maintenance. For a complete functional description refer to TDMA 1900 Macrocell RF Frame Description, 411-6201-113.If an alarm exists, perform the ATC troubleshooting procedure as described in Chapter 3, Troubleshooting at the cell site, in TDMA 1900 Macrocell Troubleshooting Guide, 411-6201-500.Transmit insertion loss testThe purpose of the forward path insertion loss test is to verify the performance of the ATC, duplexer transmit (forward) filter, and all RF cables and connection between the TRU and the duplexer antenna connector. The test involves measuring the RF power output at the duplexer antenna connector for each TRU/PA pair, then comparing that power measurement to the power measurement taken at the PA RF output connector. The difference between the two measured power levels should be less than 4.9 dB. This test also will verify SCLPA output power.CAUTIONRF Radiation HazardDO NOT disconnect an RF cable from the ATC if there is RF power applied to that cable.CAUTIONDamage to Test EquipmentBe aware of and adhere to the signal input limits of all test equipment used in these procedures.

9-1Wireless Solutions TDMA 1900 Macrocell Cell Site Maintenance Manual MTX089Miscellaneous equipment testsRRM (Remote Receive Module)There are no operational tests for the Remote Receive Module (RRM) at the cell site. If you want to check the operation of the RRM, refer to TDMA 1900 Macrocell Troubleshooting Guide, 411-6201-501.LRM (Local Receiver Module)The LRM primary function is to amplify receive band signals received from the antenna/RRM prior to distribution to the splitters and coaxial cables which connect to the transceiver shelves.Rotating the LRM attenuator switches on both LRM’s (LRM X and LRM X’) should cause the RSSI to change by approximately 1/2 dB per setting. The total range of the switch settings is approximately 6 dB. The function of the switch is to introduce a specific level of attenuation to a receive path to maintain a constant level across all receive paths. Refer to TDMA 1900 Macrocell Cell Site RF Deployment Guide, 411-6201-200.There is no scheduled maintenance for the Local Receive Module. If you suspect a fault in the LRM refer to TDMA 1900 Macrocell Troubleshooting Guide, 411-6201-501.RPDU (Receive Power Distribution Unit)There are no operational tests for the RPDU at the cell site. If you want to check the operation of the RPDU, refer to the TDMA 1900 Macrocell Troubleshooting Guide, 411-6201-501.ICRM (Intergrated Cellular Remote Module)There are no operational tests for the Integrated Cellular Remote Module (ICRM) at the cell site. If you want to check the operation of the ICRM, contact the operator at the MTX for assistance. For a functional description refer to TDMA 1900 Macrocell CE Frame Description, 411-6201-112.Other equipmentCE and RF frame equipment not already specifically mentioned do not require periodic maintenance.
9-2 Miscellaneous equipment tests411-6201-500 Preliminary 03.03 July 1999Transmission facilitiesTransmission facilities include pressurized transmission lines, microwave radio equipment and any copper facilities. It is important that your facilities are in good condition, otherwise cell site performance might be compromised. See recommended maintenance intervals from the manufacturer for the specific equipment.MicrowaveRefer to the manufacturer’s instructions for periodic maintenance. Transmission level and noise tests should be conducted once a year.Copper Audio LinkThe susceptibility of copper to noise and level problems requires more frequent checks then digital or microwave facilities. Perform noise and level checks quarterly on the T-1 transmission facilities.PowerClean, reliable power is essential to your cell site. The following are generic periodic maintenance recommendations. Consult the manufacturer's documentation for specific maintenance and specifications.Acid safety equipmentBefore you do anything in a liquid-electrolyte battery plant, make sure you have proper acid-handling safety equipment available and in good condition. The following equipment is recommended:• face shield• rubber gloves• rubber apron• eye wash station• neutralizing powder and solution to clean up spillsBatteryGell cell batteries are virtually maintenance free. Liquid-electrolyte batteries, however, require monthly maintenance refer to manufacturer's recommendation. Each month:• check the cell voltages and note any discrepancies; Increase the rectifier output voltage from float voltage to equalizing voltage for 24 hours; If the low cells are still low, replace them• check electrolyte levels and top up with distilled water• check exhaust system and hydrogen sensor (if equipped)
Miscellaneous equipment tests 9-3Wireless Solutions TDMA 1900 Macrocell Cell Site Maintenance Manual MTX08RectifiersCheck the rectifier output voltage once a month refer to manufacturer's recommendation. Check the high and low voltage alarm/cut-out sections once a year.Main generatorsSome cell sites may not have access to public mains service; instead, they are powered by on-site generators. At the very least you should:• keep records of coolant and oil temperatures and operating times• monitor fuel, oil and coolant levels• follow manufacturer’s recommendations for oil and coolant changes and periodic inspection and overhaulBackup generatorsSome sites will have backup generators. Every three months, verify that the generators start and operate correctly by removing AC power from the cell site. You should also:• monitor fuel, oil and coolant levels and record operating times• record generator readings • follow manufacturer’s recommendations for oil and coolant changes and periodic inspection and overhaulBuilding serviceIf the building uses AC mains service from overhead poles, take a look at the drop and service entrance once a year. Look for obviously damaged insulation and threats from overhanging trees.Cabling and connectionsWhenever equipment is installed or changed, check the cabling and connections. Take note of any suspect cables that give you problems from time to time.
9-4 Miscellaneous equipment tests411-6201-500 Preliminary 03.03 July 1999Inside groundingInside grounding performs two functions: it prevents noise from one unit getting into other equipment, and it ties all equipment together for protection. Check for and repair any deterioration and corrosion of the grounding system, you should also check to see that all new equipment installed in the building is grounded properly. Refer to Power, Ground, and System Cabling for TDMA 1900 Macrocell, IM 16-1753.Frame bondingIndividual frames in a line-up should be bonded together with 3/8 inch or larger bolts with star washers bearing on clean metal. Ground cablingGround cables (battery return and chassis ground) run between each frame and a customer-supplied common ground point. The specific number of frames, and the type and location of customer-supplied power and ground equipment, determines the detailed power and ground cabling requirements. Site-specific power, ground, and system cabling information is provided in the job specification documents and in the Interconnect Schematic (IS) documents.Check the ground for each frame, ensure that the frame ground cable (green) from one of the frame ground points, runs to the site common ground point . The cable must be #6AWG or larger. Ensure the cable is neat and observe the minimum bend radius specifications. Battery return cables connect to the CE frame and to the RF frames on a bus bar in the RIP of each frame. In the RIP, the center (of three) bus bars is the battery return bus bar. The cables run to the site common ground point. The two battery return cables are connected to the battery return bus bar of the RF frame RIP. Minimum size of the cable is #2/0AWG. Each cable is required to carry approximately 110 Amps of current for a fully-provisioned frame. Ensure the cables run to the site common ground point, and are connected to the common ground point using the same technique and equipment as is used for other cables at the common ground point.Check all connections and ensure that new or changed equipment is properly grounded. If there is a water pipe in the building, the principle ground bar should be connected to it.Transmission line entranceThe transmission line to the antennas should be lightning protected where it comes into the building. Check the condition of the grounding connections once a year and also following any severe lightning storm activity.
Miscellaneous equipment tests 9-5Wireless Solutions TDMA 1900 Macrocell Cell Site Maintenance Manual MTX08Outside groundingA typical cell site, with its tall metal structures and antennas, is an open invitation to a lightning strike. To avoid cell site degradation or total loss due to electrical storm activity, inspect the grounding system just before the local thunderstorm season. Checking the outside ground can be part of a site walk-around check, also checking antennas, cables, structures, lighting and foundations.Tower and associated structuresUse a pair of binoculars or a spotting scope to verify that the air terminal (lightning rod) and antennas are still attached to the tower and grounding system. Verify that:• the antenna feed cables are grounded at both ends• the cables and clamps attaching the tower and waveguide bridge to the grounding system are secure• the cables and clamps connecting the guy wires to the grounding system are secure• transmission cables are grounded at both the top and the bottom of the tower, and at the building entrance.Building sheath, fences and other equipmentIf the building has metal walls, roof or base, the metal components must be grounded. The cell site fence and any fuel tanks or other metal structures must be grounded as well. Check that the grounding cables and clamps are secure.Antennas and towerGeneral structureDetailed inspection of towers should be performed every one to three years by an experienced inspector who can climb the tower and check all components. Cell site maintenance personnel can perform an effective partial inspection without leaving the ground, and this is recommended: • once a year• following a severe storm• following a prolonged period of heavy icingUse binoculars or a spotting scope if necessary. To perform a partial inspection:• check the tower base for cracks, concrete break up and upheaval• check all guy anchors for cracks or upheaval• check guy tension and attachment• check fasteners for security• check all components for rust• check for flaking paint (often a sign of over-stress)
9-6 Miscellaneous equipment tests411-6201-500 Preliminary 03.03 July 1999Tower lightingAt every visit visually confirm operation of the tower lights at the site after dark. When the tower is climbed for structural inspection, the lights should be thoroughly checked at the same time.GroundingCheck all grounding that is accessible from the surface during your outside grounding check for corrosion and damage. When the tower is climbed for structural inspection, grounding on the higher parts of the tower should be checked at the same time.PaintPainted towers need to be re-painted every few years. Check the over all condition of the paint on an annual basis and re-paint as necessary.FeedCheck that the transmission line is adequately supported and protected between the cell site building and the antenna tower. AntennasWhen the tower is climbed for structural inspection, antennas should be inspected as well. Check for:• correct orientation and tilt• crack, dents and burns• fasteners, attachment and security• transmission line and ground attachment security• audible gas leakage in pressurized systemsPressurized transmission linesIf a pressurized transmission line to the antenna is used, check the nitrogen tank pressure and manifold pressure every visit. Check the dehydrator at the same time.Site performanceThe ultimate measure of the condition of the cell site is the actual measured performance. Site performance should be tested once a year and can be gauged by the following tests. It should be taken into consideration that coverage and handoffs can be impacted by seasons and weather.
Miscellaneous equipment tests 9-7Wireless Solutions TDMA 1900 Macrocell Cell Site Maintenance Manual MTX08Fringe coverageUsing the most recent coverage maps, take a test mobile and drive to the fringe of the site coverage area with a call established to confirm coverage. Most mobiles are able to access signal strength function mode.Handoff checksUsing the “standard drive” defined for the site or system acceptance procedures, drive across the cell boundaries with a call established. Confirm that the handoffs occur in the appropriate places and that there is sufficient hysteresis to prevent ping-ponging of calls. Use a test mobile with channel-indicating firmware to check the exact location of the handoffs.HousekeepingSecurityCheck fences, gates, barbed wire and razor ribbon, both around the building and around the tower guy anchors. Check door locks and gate locks before leaving the site.Heating/air conditioningEvery visitProper air conditioning is essential to the functioning of your cell site; so essential, in fact, that many companies choose to contract out the maintenance to a specialty company. When responsible for the heating, ventilation and air conditioning (HVAC) of the cell site, the most important thing is to make sure that the filters are clean; refer to the manufacture’s equipment manual for specific maintenance recommendations. Check thermostat setting at the site, recommended setting is 19° to 22°C. Verify HVAC operation by varying the thermostat .Annual visit All HVAC equipment should be inspected at least once a year. Check for insects, mice and bird nests in the intake and exhaust systems in the fall and the spring. Refer to the manufacture’s equipment manual for specific annual maintenance recommendations. Dust controlKeep dust levels to a minimum by mopping the floors once a month, taking care not to get the equipment wet. Whenever you remove a transceiver or power amplifier, wipe off the dust on the unit and shelf slides. Dust accumulation on circuit boards and heat sinks interferes with heat dissipation and shortens the life of the equipment.
9-8 Miscellaneous equipment tests411-6201-500 Preliminary 03.03 July 1999Equipment fansAccumulation of dust can clog fans, raising the equipment operating temperature. All frame equipment fans should be cleaned quarterly or sooner depending on the site location.Trash and loose articlesKeep the inside of your cell site as clean and tidy as possible. Trash and loose articles pose fire and tripping hazards and should be removed after every visit.Site groundskeepingTall grass can present a fire hazard; poorly kept trees can lean on or fall on buildings and equipment. Snow and ice removal on and around the site may be a statutory or legal liability requirement in some jurisdictions. Grounds keeping is often contracted out to a specialty firm.Keep the cell site grounds clean and clear, removing any trash or unnecessary material.AdministrationStatutory requirementsFire equipment, hazard signs and exit signs may be required by law. Make sure required signs are present and safety equipment is maintained.Site licensesRadio and tower and business licenses are often required to operate a cell site. Check once a year to ensure that they are being maintained, whether they are located on the site or with the company’s legal department.
