2. Introduction
LGP Allgon AR 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.
An AR 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. As an
alternative to the donor antenna, the repeater can be connected to the
base station via an optic fiber cable.
Control of the repeaters is performed using a desktop or notebook loaded
with the LGP 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 PSTN or a GSM
net.
To be able to control many LGP Allgon AR repeaters in common, there is
an LGP Allgon OMS, Operation and Maintenance System.
The AR repeaters are described in this manual. OMT32 is described in
the OMT32, User’s Manual.

Repeater Overview
The AR repeater family includes the following main repeater types:
•Channel selective GSM repeater.
•Channel selective CDMA/WCDMA repeater.
•Channel selective high power CDMA/WCDMA repeater.
•Band selective repeater.
•Combined repeater.
•BMU, Base station Master Unit.
•RMU, Repeater Master Unit.
•FOR, Fiber Optic Repeater.
These main repeater types are briefly described below.
In this document, 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
This repeater is used for channel selective systems such as GSM, DCS,
PCN and PCS.
The channel selective GSM repeater has an RF port for a donor antenna
(or RF cable) and an RF port for a service antenna (or RF cable).
Channel selective CDMA/WCDMA repeaters
These repeater types are used for digital code division systems in
accordance with IS-95 or J-std-008 standard, and wideband digital code
division systems.
The channel selective CDMA/WCDMA repeaters have an RF port for a
donor antenna (or RF cable) and an RF port for a service antenna (or RF
cable).
Channel selective high power CDMA/WCDMA repeaters
These are CDMA/WCDMA repeaters equipped with a 6dB (typically) BA
(Booster Amplifier) in the downlink transmitting signal path.
The channel selective high power CDMA/WCDMA repeaters have an RF
port for a donor antenna (or RF cable) and an high power RF port for a
service antenna (or RF cable).

Band selective repeater
This repeater type is used for analog or digital systems such as NMT,
GSM, TACS, ETACS, AMPS, DAMPS, CDMA and WCDMA.
The band selective repeater has an RF port for a donor antenna (or RF
cable) and an RF port for a service antenna (or RF cable).
Combined repeater
Some of the repeater types can be combined in the same repeater chassis
and be in operation in parallel.
The combined repeater has normally two RF ports for donor antennas (or
RF cables) and two RF ports for service antennas (or RF cables).
BMU, Base Station Master Unit
A BMU is one of the RF repeater types equipped with a FOU (Fiber Optic
Unit) that makes the repeater receive and transmit optic signals on the
service side.
The BMU has an RF port for BTS connection and up to four fiber optic
ports that can be connected to FORs.
RMU, Repeater Master Unit
An RMU is one of the RF repeater types equipped with a FOU (Fiber
Optic Unit) that makes the repeater receive and transmit optic signals on
the service side.
The RMU has an RF port for a donor antenna and up to four fiber optic
ports that can be connected to FORs.
FOR, Fiber Optic Repeater
A FOR is one of the RF repeater types equipped with a FOU that makes
the repeater receive and transmit optic signals on the donor side.
The FOR has a fiber optic donor port and an RF port for a service
antenna (or RF cable). By equipping a FOR with a splitter, another FOR
can be connected in serial.
This unit can be connected to a BMU, RMU or FOR (with splitter).

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 LGP Allgon repeater, which can be installed with a
minimum of investments, is a 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.
or?¦6cro H|H#H LGP Allgon AB
¤aV
Shaded Area
A valley is shaded by hills. There is a base station 5 kilometers away, but
the lowest signal strength in the valley is less than –100dBm. A mast used
for other purposes is available for a repeater installation. The mast height
is 42 meter and it is located on a hill. The scenario is illustrated in
Figure 2-2.
The donor antenna of the repeater was mounted at the top of the mast
and the service antenna was mounted at the half mast. The antenna
isolation was measured to over 100dB. The repeater was set to 80dB gain.
Measured levels: Received signal level – 60.0 dBm
Donor antenna gain 15.0 dBi
Cable loss – 5.0 dB
Repeater input level – 50.0 dBm
Adjusted repeater gain 70.0 dB
Repeater output level 20.0 dBm
Cable loss – 5.0 dB
Service antenna gain 8.0 dBi
Radiated output level 23.0 dBm
The measured result in the valley was better than –90dBm.

Sports Arena
A 2000 spectators sports arena with metallic roof had an indoor signal
strength too low to provide a fair service in most parts of the arena. The
nearest base station was 8 kilometers away and it was equipped with one
carrier only.
A donor antenna directed towards the base station was mounted on a
mast outside the building and a repeater was installed inside the building
with the service antenna on the arch vault. The scenario is illustrated in
Figure 2-3.
The antenna isolation was measured to over 85dB.
Measured levels: Received signal level – 80.0 dBm
Donor antenna gain 15.0 dBi
Cable loss – 5.0 dB
Repeater input level – 70.0 dBm
Adjusted repeater gain 75.0 dB
Repeater output level 5.0 dBm
Cable loss – 2.0 dB
Service antenna gain 7.0 dBi
Radiated output level 10.0 dBm
The signal strength was fair for service in the entire arena.

Fiber Optic Distribution Net
The following two examples illustrate a part of a road covered by means
of a BMU or an RMU and four FORs in a fiber optic distribution net.
Figure 2-4 shows a BMU fed via an RF cable from the BTS and four fiber
optic ports that feed four FORs in parallel. The BMU has to be located
very close to the BTS.
Figure 2-5 shows an RMU with a donor antenna and one fiber optic port
that feeds four FORs in serial.
By using WDMs and OSPs in the fiber optic repeaters, the optic
distribution net can be built up with a combination of serial and parallel
connections with double or single fiber communication.

3. Installation
Before installation, read carefully Chapter 1, Safety.
Siting the Repeater
LGP 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. A shelter can be used
to shade the repeater from direct sunshine.
Shelter
LGP 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.
LGP 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:
–Intense rainfall, snowfall or hail.
–Storm or high wind.
–Extremely low or high temperature.
–High humidity of the air.

Dimensions and Weights
The dimensions of the repeater, including the mounting bracket, is shown
in Figure 3-1. The repeater chassis consists of two main parts, a cabinet in
which the circuitry is housed, and a cover, which can be either a low cover
or a high cover (see the figure) depending on the repeater type.
The high power CDMA and WCDMA repeaters have an external heat sink
on a high cover, see Figure 3-2.

Mounting
The AR repeater is easy to mount using the provided mounting bracket,
which has Ø14mm (9/16") holes for 10mm (3/8") or 12mm (1/2") fixing
screws. Clamps with c-c measures of 90mm (3.5"), 135mm (5.3"), 144mm
(5.7"), 205mm (8.1"), 250mm (9.8"), and 300mm (11.8") can be used as
well. The vertical c-c measure for these are 411mm (16.2").
The mounting bracket is shown in the figure.
NOTE! There is a Ø14mm (9/16") single hole in the middle of the
mounting bracket, marked ’A’ in the figure, which is intended for a
locking screw, i.e. a screw which cannot be removed when the repeater is
put in the bracket.
Mount the repeater as follows:
1. Mount the provided bracket.
Normally, the repeater is mounted on a wall, pole, or mast. These
mounting cases are shown below.
Figure 3-3 shows a bracket attachment to a wall using four fixing
screws and a locking screw.

Connection
This section describes how to connect the input and output ports of the
repeater types:
AR repeaters (except for high power CDMA/WCDMA) ................ page 3-8
High power CDMA/WCDMA .................................................................... 3-9
BMU ............................................................................................................. 3-10
RMU ............................................................................................................. 3-11
FOR .............................................................................................................. 3-12
Common important instructions for the repeater types are found below.
Station ground
There is a screw to the left in the repeater that is intended for station
ground only. This screw is marked with the ground symbol.
Mains connection
Note that local regulations are to be followed for the mains connection.
The AR repeater is approved in accordance with EN and UL/cUL
regulations. This is, however, only valid if a classified power cord is used.
To get the repeater to meet these regulations, select one of the following
classified and approved cord types:
•EN – H 05 W5 - F HMR.
•UL – AWM Style 2587.
•CSA – AWM 1 A/B 11 A/B.
For outdoor use the power cord should meet at least IP65 encapsulation
requirements.
For repeaters supplied from the mains, the mains outlet must be grounded.
The mains connection described on the following pages means to mount
the mains plug to the mains cord (if to be used) but it does not mean to
connect the mains.
Do not turn the mains on until you are commissioning the repeater (see
Chapter 4, Commissioning).
RCU and RCC remote control units
All AR repeaters can be equipped with an RCU, Remote Control Unit.
The GSM antenna for this unit is internally connected in the repeater.
The RCU and its connection is described in Chapter 6, Optionals.
If the RCU is removed, then the jumper between pin 2 and 3 on the P27
port must be reconnected. Do not connect the jumper to another position
than between pin 2 and 3 on the P27 port.
An RCC, Remote Communication Control unit, is required if the unit is to
be connected to a FON board (the FON board does not support the RCU).
A description of the RCC and its connection is found in the VD203 67/EN,
ALR Compact Repeater, User’s Manual. See also Chapter 6, Optionals.

5. Functional Description
This chapter contains a short general description. After that you will find
descriptions of the various repeater types on a unit level, including
repeater types, design, block diagrams, board and sub unit descriptions,
connection ports, and cabling.
General Description
LGP Allgon AR 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 can be connected to a BS donor antenna, directed towards
the base station, and to an MS service antenna directed towards the area
to be covered. These antennas are connected to the repeater with N type
male connectors.
The repeaters can also be connected via RF cables or fiber optic cables
instead of donor or service antennas.
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. For channel selective CDMA repeaters,
poor antenna isolation is detected and managed by means of an MRX unit
(Measurement Receiver).
The LGP Allgon repeaters are controlled by powerful microprocessors.
Alarm and operational status 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 LGP Allgon OMT32, which
communicate, locally or remotely via modem, with the repeater. Remote
operation is performed via PSTN or a GSM net.

Repeater Design
The repeater is housed in a cast aluminium chassis that is waterproof,
class NEMA4/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 be either a low
cover or a high cover. The latter consists of another cabinet which can be
used as an empty cover or be equipped as a part of the repeater or as an
independent repeater unit.
Inside the repeater, a number of amplifier boards are individually shielded
and located under a metal cover that can be folded out. These amplifier
boards are of different types depending on the supported system.
A repeater with a high cover that is equipped as two independent repeater
units (Combi) can, for example, be equipped for channel selective
operation in the cabinet and band selective operation in the cover.
Functionally, all the repeater types are built up with a number of sub
units. These are listed below and pointed out in the following sections.
Sub Unit Overview
The main repeater sub units are:
CHA, Channel Amplifier board
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).
CSA, CDMA/WCDMA Segment Amplifier board
Channel selective CDMA/WCDMA repeaters can handle two CDMA or
WCDMA 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.
BSA, Band selective amplifier board
Band selective repeaters can handle multi-carriers over a wide band. The
bandwidth is adjustable. 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.
¦o6cro#fH6c|cro H|H#H LGP Allgon AB
SaV
PA, Power Amplifier board
This is a power amplifier board that can handle two repeater channels.
For every even number of repeater channels, two PA amplifier boards are
required in the repeater, one pair for uplink signaling and one pair for
downlink signaling.
The PA board is used with CSA boards in CDMA and WCDMA repeaters,
and with BSA boards in band selective repeaters.
BA, Booster Amplifier
CDMA and WCDMA repeaters can be equipped with a high power booster
amplifier that boosts the output gain with typically 6dB. A high power
CDMA or WCDMA repeater can operate with maximum two channels.
DIA, Distribution board
The DIA board is a distribution board on which all other boards and units
are connected to.
A DIA board is found in the cabinet. Another DIA board is found in the
cover, if equipped as an independent repeater.
On the DIA board, there is a shielded metal frame in which the CU, ALI
and MRX boards are located.
CU, Control Unit board
The CU board is the control unit of the repeater.
The CU board is found in the right part of the shielded DIA board frame.
ALI, Alarm Interface board
The ALI board handles alarm and alarm communication.
The ALI board is found in the left part of the shielded DIA board frame.
DC, Directional Coupler
DC units are used as antenna signal directional couplers.
DC units are found in shielded boxes to the left and right in the cabinet
(at the antenna flanges) and in some repeater types also in the cover.
LNA, Low Noise Amplifier
LNA amplifiers are used as uplink and downlink low noise branch
amplifiers.
LNA units are found in shielded boxes in the upper part of the cabinet. In
some types, they can also be found in the upper part of the cover.

SaS
DPX, Duplex filter
Duplex filters are found on the cover plate over the amplifier boards.
CMB, Combiner unit
CMB units are found on the cover plate over the amplifier boards in
channel selective repeaters with more than two channels, and in combined
repeaters.
MRX, Measurement Receiver board
Channel selective CDMA repeaters can be equipped with an MRX unit.
For such a repeater, an MRX board is found in the right part of the
shielded DIA board frame.
FOU, Fiber Optic Unit
The FOU is, in the simplest configuration, a metal plate on which a FON
board (or the earlier FOT board), a duplex filter and fiber optic
connectors are assembled. The FOU can, however, be configured with
combiners, OSPs and WDMs to obtain a desired combination of several
branches with double or single fiber communication.
The FOU is used in BMUs, RMUs and FORs.
FON, Fiber Optic Node board
The FON board is a unit that converts RF signals to optic signals and the
other way round. Also, it supervises the RF and optical signals and
generates alarm if an error occurs. Actually, it has most of the repeater
functions except for channel boards.
The FON board is built up on a printed circuit board that also contains
battery backup.
The FON is the main part of the FOU.
FOT, Fiber Optic Transceiver
The FOT unit is an earlier version of the FON board. It converts RF
signals to optic signals in the same way as the FON board, but it has not
as many functions as the FON board.
The FOT is the main part of the FOU.
PSU, Power Supply Unit
In all the repeater types, a PSU is found downmost in the cabinet. In
some types, it can also be found in the cover.

Downlink signal path
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.
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 SAW bandpass filters and, not shown in the
figure, amplified before it is fed to the second mixer stage for conversion
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.

Downlink signal path
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.
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 SAW bandpass filters and, not shown in the
figure, amplified before it is fed to the second mixer stage for conversion
back to the original frequency.
The following amplifier on the CSA board is controlled by the CU unit.
The output gain can be reduced to avoid instability due to poor antenna
isolation by means of the gain control in the MRX unit. The MRX gain
control affects also other amplification stages.
The output signal from the amplifier is fed to a combiner that combines
the signals from the two channels on the CSA board.
The signal from the CSA board is amplified on the PA board and then fed
to a duplex filter (DPX) or, in high power CDMA repeaters, to a booster
amplifier board (BA).
The amplified output signal passes the duplex filter (DPX) and a
directional coupler (DC) before it is fed to the repeater MS antenna.
High power CDMA/WCDMA repeaters
In high power CDMA or WCDMA repeaters, a booster amplifier (BA)
boosts the output downlink signal from the PA board by typically 6dB.
The amplified signal is fed to the duplex filter (DPX).
Only the downlink path in high power CDMA repeaters has a BA booster
amplifier.
The BA amplifier is powered by a separate power supply unit (PSU2).
CDMA repeaters with MRX
In CDMA repeaters, the output and input signals are measured at the MS
and BS directional couplers (DC) by means of the MRX unit. The MRX
unit continuously supervises the signal levels and controls the output gain
levels via the CU unit to avoid self oscillation due to permanently or
temporarily decreased antenna isolation.
The MRX unit offers also spectrum analyzis features further described in
the OMT32, User’s Manual.
RCU is described on page 5-30.

Downlink signal path
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 band selective amplifier board (BSA).
The first mixer stage on the BSA amplifier board, which is controlled by a
synthesizer, converts the received frequency down to the IF frequency.
The signal is then filtered by SAW bandpass filters and, not shown in the
figure, amplified before it is fed to the second mixer stage for conversion
back to the original frequency.
The BSA board has adjustable bandwidth and the SAW filter combination
can be software changed from OMT32 (or OMS).
The following power amplifier is controlled by the CU unit. The amplifier
gain will be reduced to avoid instability due to poor antenna isolation.
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 also other amplification
stages.
The output signal passes duplex filter (DPX) and a directional coupler
(DC) before it is fed to the repeater MS antenna.

RCU
The optional RCU Remote Control Unit is located inside the repeater
(described in Chapter 6, Optionals).
Communication with the repeater is performed by means of a GSM
modem that has the antenna connected to the BS directional coupler (DC)
or has a separate antenna. Data is transferred between the repeater and
the RCU via the P32 modem port.
The RCU unit is powered via the P27 auxiliary port and the unit has a
battery with a capacity enough for sending a number of alarms if a mains
power failure occurs.
RCC
The optional RCC Remote Communication Control unit is an alternative
to the RCU, provided the repeater has a FON board. The RCC unit is also
used in the Compact repeaters.
An RCC unit is required if the communication unit has to be connected to
a FON board, e.g. in the BMU (the FON board does not support the RCU).
Communication with the repeater is performed by means of a PSTN or
RF modem that has the antenna connected to the BS directional coupler
(DC) or has a separate antenna. Data is transferred between the repeater
and the RCC unit via the P130 port on the FON board.
The RCC unit is also powered via the P130 port and the unit has a
battery with capacity enough for sending a number of alarms if a mains
power failure occurs.
A description of the RCC and its connection is found in the VD203 67/EN,
ALR Compact Repeater, User’s Manual.
R2R
The optional R2R Repeater to Repeater Link feature makes it possible to
communicate with a number of repeaters via one RCU unit in one of the
repeaters in an R2R net. Several RCU units can also be used in the same
net.
The repeaters in the R2R net are connected to the P34 port.
The R2R feature is described in Chapter 6, Optionals.
¦o6cro#fH6c|cro H|H#H LGP Allgon AB
Sa®
F2F
The F2F feature makes it possible to communicate with all repeaters that
have a FON board (i.e. BMU, RMU and FOR) and are included in the
same fiber optic net. By using the existing fiber optic distribution net, no
wire or other communication device is required.
Communication with repeaters in a mixed F2F and R2R net is possible.
Alarm
Alarm signals from external sensors are received by the ALI board, which
forwards the alarm signals to the CU board.
The software on the CU board is able to activate acoustic or visual alarm
or direct the alarm to the P33 alarm port to be forwarded, via the RCU
unit, to OMT32 (or OMS) located in an operation and maintenance
central.
Alarms can also be handled by the FON board in fiber optic units, e.g. the
BMU that has no CU board or ALI board.
Alarms can be configured from OMT32 (or OMS).
Repeater Setup
The repeater parameters can be set locally by means of a desktop or
notebook running OMT32.
The PC is connected to the CU via the P31 PC port. See the block
diagrams (e.g. Figure 5-9 on page 5-18).
If the repeater has no CU unit but a FON board (e.g. the BMU), then the
desktop or notebook is connected to the P106 port on the FON board (see
Figure 5-12 on page 5-24).
If the repeater has an RCU or RCC, then the repeater parameters can be
set remotely by means of a desktop or notebook running OMT32 or OMS
and a modem.

CU – Control Unit Board
The CU board is the central board in the repeater, located in the repeater
cabinet (see Figure 5-1 to Figure 5-5). 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 OMT32, locally or remotely
via modem, or OMS.
The CU software can be downloaded from OMT32, either locally or
remotely, or from OMS.
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
u®u,r#?~rf? 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.
u®¤,r#?~6¦Ho 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 OMT32, User’s Manual).
Compatibility for CU boards and CU software is detailed on page 5-67.
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 LGP Allgon for repair.

MRX – Measurement Receiver Board
Channel selective CDMA repeaters are equipped with an MRX
(Measurement Receiver) that continuously supervises the signal levels and
controls the output gain levels via the CU unit to avoid self oscillation due
to permanently or temporarily decreased antenna isolation.
The MRX board is shown in Figure 5-16.
The four LEDs (POWER, BOOT, FAULT and OPER) have the same
function as the CU unit, described in Chapter 4.
The MRX board is located in the frame on the DIA board, see the
repeater units on page 5-9 and page 5-10.
The MRX unit is also shown in the CDMA block diagram on page 5-20.
Connection
MRX
Port Connected to
P101 MRX on the DC/MS directional coupler.
P102 MRX on the DC/BS directional coupler.
MRX function
The main task of the MRX unit is to supervise the channel spectrum of
active CDMA channels in a channel selective CDMA 800/1900 repeater in
order to maximize gain and output power, and to minimize problems as
low antenna isolation and poor antenna matching.
The MRX unit also offers spectrum monitoring and return loss
measurement.

Antenna isolation
The MRX unit automatically supervises the antenna isolation. The system
will detect both the margins to instability and full self-oscillation.
Two different alarm types (Warning and Ceasing) can be sent by the
MRX unit due to poor antenna isolation:
–If a low margin to instability is detected, then a Warning alarm is
sent and the gain is reduced gradually to a preset value.
–If the MRX unit detects self-oscillation, then a Warning alarm is sent
and the gain is reduced to the same preset value.
–When the MRX unit no longer senses any isolation problems a
Ceasing signal is sent and the gain is increased to the level set by the
operator.
Return loss (VSWR)
The MRX unit will automatically and continuously supervise both the
donor and the service antennas. The operator can, however, also manually
start a measurement of a desired antenna simply by selecting a CDMA
antenna, which will then be used for the measurement.
A Warning alarm is sent when the return loss is below an alarm
threshold that is set by the operator. When the return loss is above the
same threshold again, a Ceasing signal is sent.
Spectrum monitoring
This feature allows the operator to perform spectrum analyzis in local or
remote mode. This is further described in the OMT32, User’s Manual.

RCC, Remote Communication Control Unit
The optional RCC Remote Communication Control unit is an alternative
to the RCU, provided the repeater has a FON board. The RCC unit is also
used in the Compact repeaters.
An RCC unit is required if the communication unit has to be connected to
a FON board, e.g. in the BMU (the FON board does not support the RCU).
Communication with the repeater is performed by means of a PSTN or
RF modem that has the antenna connected to the BS directional coupler
(DC) or has a separate antenna. Data is transferred between the repeater
and the RCC unit via the P130 modem port on the FON board.
The RCC unit is also powered via the same port and the unit has a
battery with capacity enough for sending a number of alarms if a mains
power failure occurs.
A description of the RCC and its connection is found in the VD203 67/EN,
ALR Compact Repeater, User’s Manual.

R2R, Repeater To Repeater Link
The LGP 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.
All LGP Allgon repeaters can be included in a R2R net (see Figure 6-3).
Channel selective repeaters, band selective repeaters, and Compact
repeaters can be mixed in the same net. For Compact repeaters, the R2R
Repeater to Repeater Link feature is standard and requires no extra
hardware or software.
AR Repeaters can either be equipped with this feature at the delivery
from LGP Allgon, or be completed with a Repeater to Repeater Link Kit,
provided the repeaters meet the below requirements.
R2R Requirements
To be able to use the Repeater to Repeater Link feature, the following DIA
board, CU board and CU software are 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.
The version of the RIA board can be detected remotely by means of the
OMT32, see the OMT32, User’s Manual.
Further information and requirements are found in the R2R installation
document, R2R, Repeater to Repeater Link Kit, Installation Guide
(part # VD202 91/EN).

Installation
The R2R, Repeater to Repeater Link, is installed as described in the R2R,
Repeater to Repeater Link Kit, Installation Guide.
At least one RCU unit (or telephone line with modem) is required for
remote communication.
Configuration
Configuration is described in the OMT32, User’s Manual.
F2F Access
Communication with repeaters in a mixed F2F and R2R net is possible.
By interconnecting a F2F net with an R2R net, all repeaters in both the
nets are accessible. FON boards are, however, required for the repeaters
included in the F2F net (the FOT board does not support the F2F
feature).

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 LGP
Allgon UPS (Uninterruptible Power Supply). The LGP Allgon UPS has an
exterior similar to the repeater which means that it can preferably be
mounted adjacent to the repeater.
7/16" Antenna Cable Connectors
A 7/16" antenna cable kit is available for all the LGP Allgon repeaters.
This kit includes 7/16" antenna connectors for uplink and downlink
antennas mounted on two repeater cable inlet flanges, and cables and
connectors for connection to the DC directional couplers inside the
repeater.
OMS, Operation and Maintenance System
The OMS, Operation and Maintenance System is an LGP 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.

7. Repeater Alarms
This chapter contains a list of those alarms which are initiated in the
repeater.
Critical, Error and Warning alarms can be sent automatically from a
repeater to an OMT32 and OMS and then be stored. These alarms can
then be viewed.
The alarm handling is described in the following manuals:
•OMT32, User’s Manual
•Advanced Repeater OMS, User’s Manual
The table starting on the following page contains those alarms that can be
generated by an AR repeater.
