AR Repeaters & OMT32
This manual describes installation, commissioning, usage, function, operation and maintenance of the Allgon AR
repeaters and the Allgon OMT32 software version R1A. The first part of the manual describes the repeater hardware and
the second part describes the OMT32 software.
Communication between Allgon AR repeaters and operators is carried out either by using Allgon OMT32 (Operation and
Maintenance Terminal), or Allgon OMS (Operation and Maintenance System), both developed by Allgon. OMT32 is
described in this manual. OMS is described in the Advanced Repeater OMS, User’s Manual.
Hardware and software mentioned in this manual are subjected to continuous development and improvement.
Consequently, there may be minor discrepancies between the information in the manual and the performance and design
of the hardware and software. Specifications, dimensions and other statements mentioned in this manual are subject to
change without notice.
In this system, the channel selective 900, 1800, and 1900 systems are called GSM, DCS and PCS respectively. These
systems may, however, have different names in different parts of the world.
In this manual, the ’<>’ brackets are used to indicate function keys contrary to a series of key strokes
’’ = the Del(ete) key, ’Del’ = D, e, l.
Allgon and its suppliers shall not be liable for any damages related to the software or hardware, or for any other damages whatsoever caused of the use of or
inability to use any Allgon product. This is applicable even if Allgon has been advised of the damage risk. Under any circumstances, Allgon’s entire liability
shall be limited to replace such defective software or hardware which was originally purchased from Allgon.

Hardware – Safety
1. Safety
Any personnel involved in installation, operation or service of the Allgon
repeaters must understand and obey the following:
• Allgon repeaters are designed to receive and amplify signals from one or
more base stations and retransmit the signals to one or more mobile
stations. Also, the repeaters are designed to receive signals from one or
more mobile stations, amplify and retransmit to the base stations. The
repeaters must be used exclusively for these purposes and nothing else.
• Repeaters supplied from the mains must be connected to grounded
outlets and in conformity with any local regulations.
• The power supply unit in repeaters supplied from the mains contains
dangerous voltage level, which can cause electric shock. Switch the
mains off prior to any work in such a repeater. Any local regulations
are to be followed when servicing repeaters.
Authorized service personnel only are allowed to service repeaters while
the mains is switched on.
• The repeater cover must be secured in opened position, e.g. by tying it
up, at outdoor repeater work. Otherwise, the cover can be closed by the
wind and cause your fingers getting pinched or your head being hit.
• When working on a repeater on high ground, e.g. on a mast or pole, be
careful not to drop parts or the entire repeater. Falling parts can cause
serious personal injury.
• Any repeater, including this repeater, will generate radio signals and
thereby give rise to electromagnetic fields that may be hazardous to the
health of any person who is extensively exposed to the signals at the
immediate proximity of the repeater and the repeater antennas.
• The CHA channel board power transistors, the PA amplifier board
BERYLLIUM OXIDE
power transistors, and the combiners (CMB) contain beryllium oxide
(BeO) that is poisonous if present as dust or smoke which can be
inhaled. The power transistors mentioned are mounted with two
screws as opposed to other transistors.
Do not file, grind, machine, or treat these parts with acid.
Warning signs are applied on boards and units that contain beryllium
oxide. These warning signs are shown in the next section.
• The coaxial cable insulation is made of PTFE, polytetrafluoro ethylene,
HYDROGEN FLUORIDE
that gives off small amounts of hydrogen fluoride when heated.
Hydrogen fluoride is poisonous. Do not use heating tools when
stripping off coaxial cable insulation.
No particular measures are to be taken in case of fire because the
emitted concentration of hydrogen fluoride is very low.
• A lithium battery is permanently mounted on the CU board. Due to
the risk of explosion, this battery must not be removed from the board.
In case of battery malfunction, replace the CU board. The old CU
board can be sent to Allgon for repair.

avoid dangerous dealing with these parts.
Static Electricity
Static electricity means no risk of personal injury but it can severely
damage essential parts of the repeater, if not handled carefully.
Parts on the printed circuit boards as well as other parts in the repeater
are sensitive to electrostatic discharge.
Never touch printed circuit boards or uninsulated conductor
surfaces unless absolutely necessary.
If you must handle printed circuit boards or uninsulated conductor
surfaces, use ESD protective equipment, or first touch the repeater
chassis with your hand and then do not move your feet on the floor.
Never let your clothes touch printed circuit boards or uninsulated
conductor surfaces.
Always store printed circuit boards in ESD-safe bags.

Hardware – Introduction
2. Introduction
Figure 2-1. Allgon AR Repeater
Allgon repeaters are used to fill out uncovered areas in cellular mobile
systems, such as base station fringe areas, road tunnels, business and
industrial buildings, etc.
A repeater receives signals from a base station, amplifies and retransmits
the signals to mobile stations. Also it receives, amplifies and retransmits
signals in the opposite direction. Both directions are served
simultaneously.
To be able to receive and transmit signals in both directions, the repeater
is connected to a donor antenna directed towards the base station and to
a service antenna directed towards the area to be covered.
Control of the repeaters is performed using a desktop or notebook loaded
with the Allgon OMT32, Operation and Maintenance Terminal, which can
communicate with the repeaters, either locally or remotely via modem.
Remote operation can be performed either via a traditional telephone line
or via a mobile phone that can be installed inside the repeater.
To be able to control many Allgon AR repeaters in common, there is an
Allgon OMS, Operation and Maintenance System.
The repeaters and the OMT32 is described in this manual. The OMS is
described in the Advanced Repeater OMS, User’s Manual.

Combined repeater
In the OMT32, the channel selective 900, 1800, and 1900 systems are
called GSM, DCS and PCS respectively, even though these systems may
have different names in other parts of the world.
Channel selective GSM repeater
A channel selective GSM repeater can be equipped with two, four, six or
eight channels. This repeater type is used for channel selective systems,
such as GSM, DCS/PCN and GSM 1900 (PCS).
Channel selective CDMA repeater
A channel selective CDMA repeater can be equipped with one or two
channels. This repeater type is used for digital code division systems in
accordance with IS-95 or J-std-008 standard.
Band selective repeater, fixed band width
A band selective repeater with fixed band width has fixed filters for a
certain band width. This repeater type is used for analog or digital
systems, such as NMT, TACS/ETACS, AMPS, DAMPS and CDMA.
Band selective repeater, adjustable band width
A band selective repeater with adjustable band width has filters that can
be set to various band widths. This repeater type is used for analog or
digital systems, such as NMT, TACS/ETACS, AMPS, DAMPS and CDMA.

Hardware – Introduction
Using Repeaters
In areas where the radio signal propagation is poor repeaters can be used
to fill out those areas which are not covered by the base station.
The following scenarios are examples on this:
Sports arenas
Fair halls
Large shopping centres
Road and railway tunnels
Indoors in buildings with metal or concrete walls
Other examples where repeaters can be used to increase the coverage are:
- Shaded areas
- Fringe coverage areas
In areas where the traffic intensity is low, it is not cost efficient to install
a base station. An Allgon repeater, which can be installed with a
minimum of investments, is a much better solution. You save installation
costs as well as operational costs.
Examples of using repeaters
Two examples are described in the following sections. An outdoor example
in a shaded valley and an indoor example in a sports arena.

3. Installation
Before installation, read carefully Chapter 1, Safety.
Siting the Repeater
Allgon repeaters are designed for outdoor usage. However, humidity and
temperature changes may have affect on the reliability. A preferable site
for the repeater is thus indoor, in a tempered and ventilated room.
Sunshine
If a repeater is placed outdoor and can be exposed to direct sunshine, it is
essential that the air can circulate around the repeater with no obstacle.
The operating temperature must not exceed +55°C due to sunshine
exposure. A shelter must be used in this case.
Shelter
Allgon repeaters are designed with a weather proof outdoor case that can
be mounted without any kind of shelter from rain, snow or hail.
If a repeater is to be opened on the site when raining, snowing, or hailing
there must be some kind of permanent or temporary shelter. This is
applicable to gentle rainfall, snowfall or hail. Limitations for very bad
weather is found in the next section.
Allgon can provide a shelter designed for these repeaters. This shelter is
shown in Figure 3-1.
Outdoor Installation and Service Limitations
Sited outdoors, the repeater must not be opened for installation or
service at bad weather, such as:

Measuring the Output Power Level
Uplink and downlink output power test ports are found on the directional
couplers (DC) at the MS and BS antenna connectors. These test ports are
marked TEST –30dB (see Figure 4-1) and are intended for measuring
using e.g. a spectrum analyzer.
The coupling is –30dB approximately. There is no directivity in these test
ports, i.e. both uplink and downlink signal can be measured.
Voltage Supply Testpoints
A number of voltage supply testpoints are available in the repeater.
These testpoints are named U7A - U7F for the 7V supply voltages and
U26 for the 26V or 10V supply voltage (26V or 10V depending on the
repeater type).
A standard multi-meter can be used on these testpoints.
The testpoints are found on the DIA board in the repeater cabinet. The
testpoint positions on the DIA board is detailed in the Board and Unit
Descriptions section in Chapter 5.
If the repeater is equipped with a second PSU, e.g. for combined
channel/band selective operation, the same set of testpoints are found on
the cover DIA board as well.
Repeater Adjustment
The repeater is now ready to be adjusted in accordance with the site
conditions and system performance requirements. Pay especial attention

5. Functional Description
Allgon repeaters work as bi-directional on-frequency amplifiers.
A repeater receives, amplifies, and retransmits signals downlink and
uplink simultaneously, i.e. from the base station via the repeater to the
mobile stations and from the mobile stations via the repeater to the base
station.
The repeater is connected to a BS antenna, directed towards the base
station, and to a MS antenna directed towards the area to be covered.
These antennas are connected to the repeater with N type male
connectors.
To prevent instability due to poor antenna isolation, a built-in antenna
isolation supervision feature reduces the gain level automatically when
poor antenna isolation is detected.
The Allgon repeaters are controlled by powerful microprocessors.
Alarm and operational LEDs are visible on the repeater front.
The repeater works with convection cooling without fan.
Operational parameters such as gain, channel number, power levels, etc.
are set using a desktop or notebook and the Allgon OMT32, which
communicate, locally or remotely via modem, with the repeater control
unit (CU). Remote operation is performed using a telephone line or a
built-in mobile phone equipped with a data interface.

AR Repeaters & OMT32
Hardware – Functional Description
Repeater Design
The repeater is housed in a cast aluminium chassis that is waterproof,
class IP65, for outdoor use. The chassis has a design suited for outdoor
use as well as indoor use.
The chassis consists of a cabinet and a cover joined with hinges. The
cabinet contains the repeater circuitry. The cover can either be a thin
cover or a large cover. The latter consists of another cabinet which can
be used as an empty cover or be equipped as an independent repeater
system.
The cover has two external LEDs for operation and alarm indication.
The cabinet as well as a large cover can be equipped for channel selective
operation or band selective operation. A combined repeater is normally
equipped for channel selective operation in the cabinet and band selective
operation in the cover.
Different amplifier boards are used to get the various operations (see
below). The amplifier boards are individually shielded and located under
metal cover sheets which can be folded out.
Channel selective GSM amplifier boards
Channel selective GSM repeaters can handle up to eight repeater channels
(four if the CU part number is K103/1). For every even number of
repeater channels, two CHA amplifier boards are required in the repeater,
one CHA board for uplink signaling and one board for downlink signaling.
Each repeater channel is allocated to a radio channel or switched off. In a
GSM type TDMA system (GSM, EGSM, DCS1800 or PCS1900), one
repeater channel can handle eight calls (sixteen if half-rate encoding is
used).
Channel selective CDMA amplifier boards
Current CDMA repeaters can handle two CDMA repeater channels. For
every even number of repeater channels, two CSA amplifier boards and
two PA amplifier boards are required in the repeater, one pair of CSA/PA
boards for uplink signaling and one pair for downlink signaling. Each
repeater channel is allocated to a radio channel or switched off.
Band selective amplifier boards
Band selective repeaters can handle one wide band repeater channel. The
band width is either fixed or adjustable (fixed for 900MHz repeaters only).
A band selective repeater channel requires two BSA boards and two PA
amplifier boards in the repeater. One pair of BSA/PA boards for uplink
signaling and one pair for downlink signaling.

Downlink
The signal from the base station is received via the repeater BS antenna
and is then forwarded through a directional coupler (DC). The signal
passes a duplex filter (DPX), is amplified in a low noise amplifier (LNA),
and enters the channel boards (CHA), which have two parallel channels
each.

Hardware – Functional Description
The first mixer stage on the CHA amplifier board, which is controlled by
a synthesizer, converts the received frequency down to the IF frequency.
The signal is then filtered by a SAW bandpass filter and, not shown in the
figure, amplified before it is fed to the second mixer stage, controlled by
the same synthesizer as the previous one, for converting back to the
original frequency.
The output signal from the mixer is then amplified in the power amplifier
and fed to a combiner, which combines the signals from the two channels
on the channel board.
The output signal passes a combiner (CMB), a duplex filter (DPX), and a
directional coupler (DC), before it is fed to the repeater MS antenna.

Figure 5-6. Block diagram, CDMA repeater
Figure 5-6 shows a block diagram of a channel selective CDMA repeater.
This diagram is applicable only to repeaters for the CDMA system.
Downlink
The signal from the base station is received via the repeater BS antenna
and is then forwarded through a directional coupler (DC). The signal
passes a duplex filter (DPX), is amplified in a low noise amplifier (LNA),
and enters the channel board (CSA), which has two parallel channels.

Hardware – Functional Description
The first mixer stage on the CSA amplifier board, which is controlled by a
synthesizer, converts the received frequency down to the IF frequency.
The signal is then filtered by a SAW bandpass filter and, not shown in the
figure, amplified before it is fed to the second mixer stage, controlled by
the same synthesizer as the previous one, for converting back to the
original frequency.
The following power amplifier is controlled by the CU. The output gain
can be reduced to avoid instability due to poor antenna isolation.
The output signal from the amplifier is fed to a combiner, which combines
the signals from the two channels on the channel board.
A detector on the PA board measures continuously the output level. The
signal from this detector is used by the automatic gain control, AGC, to
supervise and, if necessary, reduce the output power to keep it under a
maximum level. The AGC gain control affects all the amplification stages.
The output signal passes a duplex filter (DPX) and a directional coupler
(DC) before it is fed to the repeater MS antenna.

The signal is then filtered by a SAW bandpass filter and, not shown in the
figure, amplified before it is fed to the second mixer stage, controlled by

The SAW filter can be either fixed or adjustable depending on the BSA

fixed and selected for the current band width. If the BSA board has
adjustable band width, the SAW filter can be software changed from
within OMT32 (or OMS) to cover various band widths.
The following power amplifier is controlled by the CU. The output gain

CU Control Unit Board
The CU board is the central board in the repeater, located in the repeater
cabinet. The CU board contains a microprocessor, main memory, flash
memory for the CU software, EEPROM memory for parameters, memory
for the event log and statistics, a REFO reference oscillator, ports for local
and remote communication, battery powered real-time clock, etc.
The CU board is used to supervise and control operational parameters
such as gain control, channel handling, etc. The CU takes care of alarms
and the event log, password and logon, and many other procedures.
The CU is also a control interface when using an OMT32/PC or an
OMS/PC locally or remotely via modem.
The CU software can be downloaded from an OMT32/PC or OMS/PC
either locally or remotely via modem.
The real-time clock on the CU board is used for alarm and for the event
log.
There are currently two CU board variants: K103/1 and K103/2.
CU board and CU software part #s
K103/1 CU board (old)
K103/2 CU board (current)
CU board K103/1 can be run with the SA102 01/2 CU software. This
board can store one version of CU software. The repeater will always
boot on this software version.
CU board K103/2 can be run with either the old SA102 01/2 CU software
or the current SA102 02/1 or SA102 02/2 CU software. This board can
store two versions of CU software, located in segment 1 and segment 2 of
the flash memory as Application 1 and Application 2. The repeater will
boot on that software which is set as Primary (description of Primary
application is found in the CU Revision Manager section in Chapter 10).
Compatibility for CU boards and CU software is detailed in the next
section.
Connection
The CU board is connected to the DIA board via the P2 port.
Caution
A lithium battery is permanently mounted on the CU board. Due to the
risk of explosion, this battery must not be removed from the board. In
case of battery malfunction, replace the CU board. The old CU board can
be sent to Allgon for repair.

6. OMT32 Installation
The OMT32 (Operation and Maintenance Terminal) is used to set up and
supervise Allgon repeaters, either locally using a desktop or notebook
connected to the repeater, or remotely via a traditional telephone line or a
cellular phone.
All Allgon AR repeaters can be controlled by using the OMT32 software.
OMT32 can, however, only take full advantage of repeaters equipped with
the latest CU software (SA102 02/1 or SA102 02/2).
In this chapter, you will find the requirements for the desktop and how to
install the OMT32 software.
Also, you will find information about automatic OMT32 start and
recovery, log file, screen savers, and how to remove OMT32 from the
system.
Requirements
The system requirements for OMT32:
100MHz Intel Pentium processor
32MB RAM
32MB free hard disk space
Monitor with a minimum resolution of 800 by 600 pixels
A free serial COM port
A Hayes compatible modem
Windows 95/98 or Windows NT 4.0 with Service Pack 3 or later. The
latest service pack can be downloaded from www.microsoft.com.
The OMT32 software is available on a CD-ROM.
If you prefer to install the software from 3.5" disks, then copy the
contents of the CD-ROM to disks. There are folders called DISK1,
DISK2, etc. on the CD-ROM which are intended to be copied to 1.44MB
disks.

Log File
The currently used log file is reflected in the Log file in old catalog field
in the OMT Log File Settings dialog box (page 6-6). In this log file all
events are continuously logged. The intention with the log file is to be
able to see what has happened in the past. The text in this file is similar
to the text shown in the OMT32 Message Log window.
The log file is a plain text file which can be viewed, edited, printed out, or
cleared using a text editor or a word processor.
If the log file is deleted or removed, a new log file is created automatically
by the OMT32.
Log File Size
Events are continuously stored in the log file. When the file reaches a
size of 64KB, the operator will be alerted about the file size. This gives
opportunity to move or delete the log file.
Log File Name and Path
By default, the log file is located in the OMT32 program folder, which e.g.
can be C:\Program Files\Allgon\OMT32R1A.
The log file name is by default allgon.txt.
A new log file with a different name or path can, however, be set by
starting the OMT Setup (see the next section) and changing the log file
name or path in the OMT Log File Settings dialog box (page 6-6).

Command Line Interface
The Command Line Interface, CLI, is provided as a quick way of
communicating with a connected repeater. Rather than using the normal
Windows dialog boxes the user can interact with the repeater more
directly.
The Command Line Interface feature does not check whether entered
values are within permitted range or not. So, you MUST know the system
very well before setting gain and power levels using the Command Line
Interface.
The CLI provides several advantages:
• Users accustomed to a keyboard based operating system do not have to
adjust immediately to an entirely novel system.
• Single parameters can be set.
• Without touching the mouse, the experienced user can perform
operations quicker.
• Using the CLI prevents the screen from getting clogged up with lots of
windows.
• Using the CLI is more memory efficient.
If the CLI is iconized, then double-click the Command Line Interface icon
or select the Command Line Interface option in the Advanced menu.
Commands can be entered on the command line like this:
By clicking
the last entered commands can be reselected, edited and
entered again.
A command list with command syntax is found below.
Command Syntax
The following command syntax is valid for the Command Line Interface:
MAIN_COMMAND-SUB_COMMAND [:PAR1, PAR2, ...];
Note that each line must be ended with a semicolon (;).
If a command is entered with an incorrect syntax, an error message with
a mismatch explanation is shown.

Operational Data in General
In this section, you will find some useful information about how to
handling the operational data, including:
• Information about what happens when modifying operational repeater
data.
• How to switch between active repeater parts when operating
combi-repeaters.
Modifying Operational Data
Changing operational data is carried out by changing data in the
operational dialog boxes and clicking the Update button.
When the Update button is activated, all data from the dialog box is
downloaded to the repeater. Changed data as well as unchanged data is
downloaded.
Then, all fields in the dialog box are blanked whereupon they are updated
with data read from the repeater.
This procedure ensures that the information shown on the monitor
corresponds to the information in the repeater.
The status window and the testpoint window are, however, continuously
updated with a time interval of 2 seconds.
This time interval is the reason to why it sometimes takes a few seconds
for these windows to be updated.

Used gain
Actual momentary gain for the uplink and downlink transmission.
The gain may differ from the setpoint value due to poor antenna isolation.
An antenna isolation test feature regulates the gain as follows:
- After powering up, resetting or updating, the gain is increased to
13dB above the Control to level (see Figure 10-8).
93dB
Control to 80dB
Figure 10-8. Antenna isolation margin test
The purpose of this 13dB ’over-gain’ is to test if there is a 13dB
antenna isolation margin. The gain increase can be seen in the
Control to and Used gain fields.
- If no instability due to poor antenna isolation is detected during the
antenna isolation test, the gain is decreased to the Control to level
after 30 sec.

Figure 10-9. Gain regulation at poor antenna isolation
- If instability due to poor antenna isolation is detected during the
antenna isolation test, the gain is decreased to a level 13dB below the
lowest detected poor antenna isolation level (see Figure 10-9).
Warning alarm is activated when instability is detected and Ceasing
when the instability has ceased.
- The decreased gain level is kept for the next 60 minutes. Then, a
new antenna isolation margin test is performed.

Output gain regulation is performed as soon as poor antenna isolation is
detected during operation.
If instability due to poor antenna isolation is detected at the lowest
output gain, the channel is blocked and BLOCK mode is indicated in the
status window. Error alarm is activated when instability is detected and
Ceasing when the instability has ceased.
A constant CW signal in the GSM frequency band is a ’jammer’ which
may be harmful to the cellular system. A BTS might, in worst case, be
disabled. The Allgon repeaters detect, however, strong CW signals. If a
constant CW signal is detected (channel board test point Power 1 or
Power 2 >27dBm), the channel is blocked and BLOCK mode is indicated
in the status window. Error alarm is activated when the channel is
blocked and Ceasing when the blocking has ceased.
Antenna isolation test and CW signal strength test are performed in the
uplink path. Gain regulation is then performed for uplink as well as
downlink using the uplink levels.
Antenna isolation test is a valuable feature to reveal isolation
problems when installing repeaters. Also, it is very useful when
making site specific repeater adjustments such as antenna
configuration (i.e. donor and service antenna vertical and horizontal
positions, beam alignment, and gain). The antenna isolation test is
also useful to reveal other environmental problems that must be
considered, e.g. reflections from buildings, masts, traffic, etc.
After performing the antenna isolation test, set the repeater gain
(Gain set to) to the value obtained (13dB under the instability level).
The repeater will then work with a safe gain margin to avoid
instability.
It is not recommended to use the repeater isolation test in an
instable environment to automatically and continuously adjust the
gain from the gain set by the operator.

Alarm Overview
Alarms are states or events in the repeaters that are more or less
detrimental to the repeater function. All alarms are classified in the
following levels depending on the extent of malfunction the alarms cause.
Alarm Levels
None
An event that is not detrimental to the repeater performance.
None alarms will never be reported. If no alarm is active, None is
indicated e.g. in the operational status window.
Warning
An alarm level that decreases the repeater performance somewhat.
A Warning alarm is not a serious alarm. It can be caused by poor
antenna isolation, low traffic activity, etc.
Error
An event indicating that a part of the repeater is not functioning. An
Error alarm is a serious alarm. It can be caused by a synthesizer fault,
external alarm, etc.
Critical
An event that makes the entire repeater cease to function. A Critical
alarm is a very serious alarm. It can be caused by a mains breakdown,
external alarm such as fire, etc.
Ceasing
An event that resets a previous alarm, i.e. the event when the cause of
the alarm ceased. Ceasing is e.g. applicable to an antenna isolation alarm,
which after some time can be ceased if poor antenna isolation is no longer
detected.
Alarm indication
Alarms are indicated with a LED on the repeater front and can be
transferred to a locally or remotely connected OMT32.
The alarm LED indication is reset by a power failure.
Combined repeaters indicate alarms for both the repeater units if an
alarm has been activated in either of the units.

The external alarm inputs, EAL1 - EAL4, can be configured for various
alarm levels and alarm purposes in the Alarm Configuration window
(description on page 11-4). Some of the alarm input purposes are
described below.
EAL1
The EAL1 external alarm input can also be used for mains breakdown
alarm. This is further detailed in the Mains Breakdown Relay section in
Chapter 3.
EAL2
The EAL2 external alarm input can also be used for battery backup alarm.
EAL3
The EAL3 external alarm input can also be used for fiber optics alarm,
provided the Fiber Optic OMT software is used.
EAL4
The EAL4 external alarm input can also be used for an alarm which is
activated if the repeater door is open.
External alarm Ceasing
The external alarm inputs can be selected with or without Ceasing.
• With ceasing, e.g. Warning w ceasing, means that activated alarms as
well as ceased alarms are reported to the OMT32. The latter as
Ceasing.
• Without Ceasing, e.g. Warning w/o ceasing, means that an activated
alarm will be reported to the OMT32. When the cause of the alarm has
ceased, the event is assigned the None level.

Authorized personnel only are allowed to dismantle any part of the
repeater at the site.
To open the repeater, use a 5mm Allen key (6mm for older repeaters).
Power Failure in General
As the entire parameter setting and channel information is stored in an
EEPROM in the repeater, all parameter and channel information remains
intact after a power failure or turn off.

Troubleshooting
Other faults
Open the repeater cover and connect an OMT32/PC to the repeater.
Open the Repeater Event Log and check the cause of the alarm.
• If an antenna isolation alarm is indicated, the antenna isolation should
be measured. It should be 10dB - 15dB higher than the repeater gain.
Check the antenna installation to ensure that nothing has happened to
it. If there is a permanent degradation of the antenna isolation, lower
the gain to 15dB below the measured antenna isolation.
Make an alarm reset.
• If the alarm is activated by an external alarm input, then remove the
cause of the alarm.
• If the alarm is indicated as RF blocking, then an external strong CW
signal can be the cause of the alarm.
The CW signal is described in the Channel Selective GSM Repeater
section under Operational Status in Chapter 10.
• If a PSU alarm is activated which appears again, then the PSU should
be replaced.
• If the alarm is internal and appears again, then a fault has probably
occurred in the repeater. Try to trace which unit has activated the
alarm and the type of the alarm. In most cases, the unit and fault type
can be detected.
• As the last resort, if nothing else helps, remove the repeater for service.

OMS, Operation and Maintenance System
The OMS, Operation and Maintenance System is an Allgon software
package for controlling a large repeater fleet by using computers with
Windows NT in networks with a common database.
The OMS is capable of operating a large number of repeaters. Multiple
modems can be used for several incoming and outgoing parallel activities,
such as polling, radio parameter configuration, software downloading, etc.
OMS is an improved OMC, Operation and Maintenance Center. The latter
is replaced by the OMS and is no longer subject to further development.
Traffic Statistics
Traffic statistics is available for channel selective GSM 900, GSM 1900
and DCS/PCN 1800 repeaters, provided that the repeaters have the latest
CU software versions, the latest CU and CHA boards, and that an OMS is
used to poll and view the statistics.
Battery Backup
Battery backup can be arranged by completing the repeater with an
Allgon UPS (Uninterruptible Power Supply). The Allgon UPS has an
exterior similar to the repeater which means that it can preferably by
mounted adjacent to the repeater.
Fiber Optic Interface
A Fiber Optic Interface that includes transmitter, receiver, alarm board
and power supply is available for all the Allgon repeaters. The fiber optic
interface can be adapted for separate uplink and downlink fiber as well as
for bi-directional one-fiber distribution.

R2R, Repeater To Repeater Link
Figure 13-4. Repeater to Repeater Link
The Allgon Repeater to Repeater Link can be used in order to establish a
repeater network with up to 13 repeaters, one or several of which can
contain a phone line for communication with an OMT32 or an OMS.
Channel selective repeaters as well as band selective repeaters can be
included and mixed in the network.
Repeaters can either be equipped with this feature at the delivery from
Allgon, or be completed with a Repeater to Repeater Link Kit, provided the
repeaters meet the following requirements.
Requirements
To be able to use the Repeater to Repeater Link feature, the following DIA
board, CU board and CU software is required:
DIA board
K105/1 version R2A or higher
CU board
K103/2 version R1A or higher
CU software SA102 02/1 version R3A or higher
Further information and requirements are found in the R2R installation
document, R2R, Repeater to Repeater Link Kit, Installation Guide
(part # VD202 91/EN).
R2R Installation

Node Configuration
The node configuration made at the installation can be changed.
To be able to change the node configuration, connect to the repeater
locally with an OMT32/PC.
Log on the repeater.
Select the Repeater Network option in the Advanced menu, and then
the Node Configuration option.
Set the node identity and the Control Station in the following dialog box:
Figure 13-5. Node configuration
Set the Network ID to a unique number between 1 and 13 for the current
repeater.
Check the Control Station box if the current repeater can handle the
communication and thus be a master repeater in the net. Several
repeaters in the same net can be selected to be Control Stations, which
means that the next selected repeater becomes the master if the previous
master of some reason has ceased to be i operation.
At least one repeater has to be selected as Control Station in an R2R net.
It is recommended to select all repeaters in the net as Control Stations,
except for fiber optic slave repeaters.
When ready, click the Update button.
Now, the repeater has to reboot to set the configuration in effect. The
following dialog box is shown:

Alarm Configuration
This configuration sets the modems to be used by the repeaters in the net
for alarm reporting to OMT32.
Open the configuration box by selecting the Repeater Network option
in the Advanced menu, and then the Alarm Modems option.
Figure 13-8. Alarm configuration
To make the explanation easy, assume that you are logged on repeater
NU 0 (NU = network unit), which can be seen in Figure 13-8 and in
Figure 13-10. If this repeater is to use repeater NU 1 and NU 2 when the
own communication fails, then these network units are added to the list
in Figure 13-8.
Now, the list contains three repeaters, NU 0, NU 1 and NU 2.
The ’Try up to’ box sets the number of attempts to report an alarm
before giving up.
The settings in Figure 13-8 will, if busy line or no answer, result in the
following call attempt cycle before giving up:
NU 0 - NU 1 - NU 2 - NU 0 - NU 1 - giving up.
This makes 5 attempts in the order set in the table.
The cycle order can be changed by selecting a network unit and clicking
the Move Up or Move Down buttons.
Modem 0 means the first modem for the repeater, but no repeater can
handle more than one modem, so Modem must always be set to 0.
