1General maintenance procedures
General precautions
There 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 hazard
Radio 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 identification
Label 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.
Caution
Radiation Hazard
Do NOT disconnect any RF cables when
transmitters are on.
1-2 General maintenance procedures
411-6201-500 Preliminary 03.03 July 1999
ElectroStatic Discharge (ESD) control
This 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 equipment
Various electrical and electronic components are vulnerable to ESD. These
include:
• discrete components
• hybrid devices
• Integrated Circuits (ICs)
• circuit boards assembled with these devices
Identification
Manufacturers 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.
Caution
Equipment Damage
Do not let the circuit board come into contact with
clothing at any time, as the grounding strap cannot
dissipate static charges on fabrics.
Equipment damage
Electrostatic discharge
When in doubt, any circuit board containing
microelectronic components must be assumed to
be vulnerable to ESD.
General maintenance procedures 1-3
Wireless Solutions TDMA 1900 Macrocell Cell Site Maintenance Manual MTX08
Static control materials and devices
Use 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 stations
Static-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 strap
Ideally however, locations should be equipped as follows when necessary
• wrist strap
• shoe grounding straps
• ionized air blower (where required)
• ground cord
• floor mats
•table mats
Where 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 procedures
Degradation 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 hazard
Metalized 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 procedures
411-6201-500 Preliminary 03.03 July 1999
mats 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.
Handling
Electrostatic-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.
Transporting
A 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 damage
Electrostatic discharge
At no time must an unprotected circuit board come
in contact with clothing, plastics, or ungrounded
personnel
General maintenance procedures 1-5
Wireless Solutions TDMA 1900 Macrocell Cell Site Maintenance Manual MTX08
Storage
Improper 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 procedures
411-6201-500 Preliminary 03.03 July 1999
Field 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.
Caution
Service Affecting
A 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 1-7
Wireless Solutions TDMA 1900 Macrocell Cell Site Maintenance Manual MTX08
11. Tag and return the faulty unit to your Nortel Customer Service Operations
office for repair.
Replacing faulty units in the Radio Frequency (RF) frame
For 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 mechanism
The 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.
Caution
Service Affecting
A 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 procedures
411-6201-500 Preliminary 03.03 July 1999
Replacement
The 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.

Wireless Solutions TDMA 1900 Macrocell Cell Site Maintenance Manual MTX08
2Test equipment
The 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-up
Do 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 calibration
Proper 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 damage
Ensure that the test equipment maximum allowable
input levels are not exceeded. Add an attenuator to
reduce the power if necessary.
2-2 Test equipment
411-6201-500 Preliminary 03.03 July 1999
RF radiation hazard
Radio 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 equipment
It 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. Communications Monitor:IFR 1900 (or equivalent) refer to appendix A
for IFR 1900 set up.
2. Interface Terminal:VT100 Video Display Terminal or equivalent laptop

Terminal interface operation
Introduction
The 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

Interfacing the terminal with the TRU
Interfacing the TRU while it is “in service”
Interfacing to the TRU with a Terminal Interface while the TRU is in-service
(active by MTX), can be established by pressing the RETURN key on the
laptop once the physical connection is made. 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 subsystem
Interfacing the TRU while it is Off-line or Manbusy
With 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:

>
For the TRUIII 1900:

(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 OFF
The 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 equipment
411-6201-500 Preliminary 03.03 July 1999
Disconnecting the Terminal Interface
Once 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 mode
The 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:
Test equipment 2-7
Wireless Solutions TDMA 1900 Macrocell Cell Site Maintenance Manual MTX08
>SET FS ON
The SET FS ON command clears the existing display and changes the
display to the Fullscreen Display in the AMPS mode. 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.
Table 2-2 (pg 2-8) is a summary of the fullscreen commands and these
commands are explained in Table 2-3 to Table 2-7.

Fullscreen commands for TDMA mode functions
Terminal interface command line mode
The Command Line Mode of the Terminal Interface can be used to execute
three types of commands:
• maintenance commands
• measurement commands
• test commands
Each type of command serves a specific function as outlined in the following
sections.
Maintenance commands
Each maintenance function may be used by an operator to aid in the diagnosis
and repair of faults in the TRU. There are periodic maintenance functions that
must be performed at regular intervals these schedules can be found in
Chapter 3, Maintenance Schedules in this manual.
Note: The Command Line mode and the Fullscreen mode are intended
for testing purposes only. Do not place the TRU into either one of these
modes during call processing. The call in progress may be dropped.
Table 2-8 gives the name, terminal command, state allowed, and description
for the command line mode maintenance commands.
TDMA mode functions (available to the TDMA mode only):
GSet DVCC 01 to FF
(hexadecimal) Sets the DVCC transmitted by the TRU when the
MPA is enabled; DVCC is an 8-bit verification code
transmitted between the mobile and the base
station; it is used in TDMA cellular to differentiate
between mobiles on the same frequency
HSet Slot 1 to 3 The TRU currently supports Full Rate (3 slots)
coding, that is, three mobiles sharing one
frequency; this command sets the current TDMA
slot used by the TRU for DVCC transmission and
signal measurements
PDetect DVCC,
RSSI -000.0
Y/N
Displays if current DVCC setting is detected and/or
the RSSI measurement on the current slot of the
antenna setup. The status will be displayed in the
RX RSSI and RX DVCC fields
TStand-alone TX On or Off Allows the TRU to transmit without using a PA. This
is used for either low power testing or on low power
cell sites

3Maintenance schedules
This 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 records
Periodic maintenance allows for
• the detection and replacement of degraded equipment before it affects
service
• preventative steps to protect equipment from damage or degradation
To 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 equipment
Manuals and records
For 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.

5Very Stable Master Oscillator (VSMO)
tests
Very 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 test
Follow the steps in Table 5-1 for the oscillator test procedures. See Figure 5-1
and Table 5-2 for IFR test set up.
Attention
Measurement discrepancy
When using the Power Meter on the IFR 1900, the
signal reading was 5.8–6.3 dB lower than the
Spectrum Analyzer value.
Table 5-1
VSMO test procedures
Step Action Observation
1Connect the communications monitor to the
output port on the back of the VSMO. SMA to N type cable required.
2Measure the output of the master oscillator
and record on the test form. 8.2dBm ±2.6dB
3Observe and record the RF frequency /
frequency error 4.8 MHz ±0.085 ppm
5-2 Very Stable Master Oscillator (VSMO) tests
411-6201-500 Preliminary 03.03 July 1999
Note 1: All unused ports should be terminated with 50-ohms for a correct
power reading.
Note 2: The VSMO is adjusted at the factory for frequency accuracy. If
the frequency test fails it must be replaced with a new unit.
Note 3: The recommended frequency counter is a:
HP 53132 A 225 MHz Universal Frequency Counter
An external 10 MHz reference into the frequency counter must be used in
order to ensure measurement accuracy (ensure external/internal reference
switch is selected to "external"). Any one of GPS, rubidium, or cesium
references may be used, or any reference that meets a minimum stability
requirement of +/- 1 x 10 -9( +/- 1 ppb). Ensure that prior to usage, that
the external frequency reference has stabilized/warmed up according to
the manufacturer's specifications and requirements.

6Antenna and Transmission line tests
Antenna direct current continuity
These 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.
CAUTION
RF Radiation Hazard
All transceiver transmitters must be turned off
before disconnecting or connecting transmit cables
to avoid RF induced injuries.
CAUTION
Service Disruption
The following tests are service affecting when the
antenna is disconnected.
6-2 Antenna and Transmission line tests
411-6201-500 Preliminary 03.03 July 1999
Table 6-1
Direct current continuity test
Antenna return loss
The 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 Generator
Spectrum Analyzer
VSWR Bridge
If 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 Observation
1Visually 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 Ω
3Measure 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.
CAUTION
Service Disruption
The following tests are service affecting when the
antenna is disconnected.

2Set the signal generator output level to 0
dBm.
3With the Device under Test (DUT) VSWR
bridge port connect to an open, adjust the
display on the spectrum analyzer to the top
of the screen.
4Connect a 50 ohm termination to the open
port on the VSWR bridge and step the
generator through the receive and transmit
band to verify the test set-up for return loss.
Return loss should be greater than 35 dB
over the bands.
5Remove the termination from the VSWR
bridge, connect the antenna jumper cable to
the open port and again step the generator
across the transmit and receive bands.

Thruline Wattmeter method (antenna return loss)
This is a service affecting test using a Thruline Wattmeter. It can be used with
transmit antennas only.
Follow steps in Table 6-3.
6Record the minimum return loss of the
antenna and transmission line in the system. Return loss: 1850 to 1910 MHz Rx
1930 to 1990 MHz Tx
The return loss typically should be 3 or 4 dB
greater then the antenna return loss as
stated by the antenna manufacturer.
7Repeat the test for each antenna installed for
the cell site.
8If the test fails, check the antenna matching,
cables and connectors.
CAUTION
RF Radiation Hazard
All transceiver transmitters must be turned off
before disconnecting or connecting transmit cables

Measure the reflected power from the antenna across the entire cellular band
(receive and transmit) to check for hidden damage or deterioration of the
antennas.
Follow the procedure in Table 6-4 for the antenna sweep test.
Table 6-4
Antenna sweep procedure
Step Action Observation
1Set up and calibrate a network analyzer
(HP8753C or equivalent) to sweep 1850 to
1990 MHz.
2Notify the Control Center to OFFLINE the
cell site.
3Connect the network analyzer to the antenna
transmission line.
4Perform a return loss sweep on the Network
Analyzer. Note the worst frequencies by
placing 2 markers each on the transmit and
receive frequencies. then print a hard copy of
the upper left quadrant.
Measured return loss of the antenna can be
calculated as:
RL (ant) = -14 dB - 2 times the antenna
cable loss
or:
Compare you results with that of the RF Path
calculated return loss of the cell site logbook
(check the RF PAth Analysis sheet).
If the results are bad compared to the log
book values connect the test cable directly to
the main transmission line and resweep.
It is possible to have a bad jumper. If the
results are still bad then the problem could
be either with the transmission line or the
antenna.
5Do a TDR sweep of the antenna. Print a hard
copy of the lower left quadrant.
6Do a SWR sweep of the antenna. Print a
hardcopy of the upper quadrant. The result
should not be higher than 1.5:1

7Tx insertion loss test
Overview
Check 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 test
The 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.
CAUTION
RF Radiation Hazard
DO NOT disconnect an RF cable from the ATC if
there is RF power applied to that cable.
CAUTION
Damage to Test Equipment
Be aware of and adhere to the signal input limits of
all test equipment used in these procedures.
7-2 Tx insertion loss test
411-6201-500 Preliminary 03.03 July 1999
Combiner insertion loss–power method
This test verifies the loss from the power amplifier output to the antenna port
of the duplexer. It also verifies that the return loss of the isolator is within
specifications. The loss characteristic is verified by comparing the power
output measured at the duplexer antenna (ANT) port with the power output
measured directly from the power amplifier. Refer to procedure in Table 7-1
and Figure 7-1.

8ACU tests
Overview
Alarm Control Unit (ACU)
The Alarm and Control Unit (ACU) provides discrete alarm monitoring,
reporting and control functions at a cell site. The site ACU concentrates all
alarm input points at the cell site and updates the MTX of any status change
over redundant data links. The MTX can also poll for the condition of the
ACU and request current status information or change the status of any output
control contact. For a complete description of the ACU, refer to TDMA 1900
Macrocell CE Frame Description, 411-6201-112.
The ACU alarm input points for equipment such as fans, over-temperature
alarms and door switches should be verified once a year. Alarm output
contacts and alarm reactions should be verified at the same time.
The MAINTENANCE (Local Terminal) port located on the front of the ACU
gives direct access to the ACU MPU (microprocessor) board. You can use this
interface to configure and monitor the alarm input points and the control
output contacts. A photo of the ACU is shown in Figure 8-1.

RRM (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.

9-2 Miscellaneous equipment tests
411-6201-500 Preliminary 03.03 July 1999
Transmission facilities
Transmission 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.
Microwave
Refer to the manufacturer’s instructions for periodic maintenance.
Transmission level and noise tests should be conducted once a year.
Copper Audio Link
The 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.
Power
Clean, 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 equipment
Before 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 spills
BatteryGell 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 9-3
Wireless Solutions TDMA 1900 Macrocell Cell Site Maintenance Manual MTX08
Rectifiers
Check 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 generators
Some 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 overhaul
Backup generators
Some 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 overhaul
Building service
If 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 connections
Whenever 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 tests
411-6201-500 Preliminary 03.03 July 1999
Inside grounding
Inside 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 bonding
Individual frames in a line-up should be bonded together with 3/8 inch or
larger bolts with star washers bearing on clean metal.
Ground cabling
Ground 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 entrance
The 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.

Wireless Solutions TDMA 1900 Macrocell Cell Site Maintenance Manual MTX08
Outside grounding
A 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 structures
Use 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 equipment
If 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 tower
General structure
Detailed 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 icing
Use 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)

Tower lighting
At 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.
Grounding
Check 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.
Paint
Painted 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.
Feed
Check that the transmission line is adequately supported and protected
between the cell site building and the antenna tower.
Antennas
When 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 systems
Pressurized transmission lines
If 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 performance
The 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 9-7
Wireless Solutions TDMA 1900 Macrocell Cell Site Maintenance Manual MTX08
Fringe coverage
Using 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 checks
Using 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.
Housekeeping
Security
Check 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 conditioning
Every visit
Proper 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 control
Keep 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 tests
411-6201-500 Preliminary 03.03 July 1999
Equipment fans
Accumulation 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 articles
Keep 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 groundskeeping
Tall 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.
Administration
Statutory requirements
Fire equipment, hazard signs and exit signs may be required by law. Make
sure required signs are present and safety equipment is maintained.
Site licenses
Radio 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.
