Safety Considerations
2.1.
Earthing of Equipment
Equipment supplied from the mains must be connected to grounded outlets and earthed
in conformity with appropriate local, national and international electricity supply and
safety regulations.
2.2.
Electric Shock Hazard
The risk of electrical shocks due to faulty mains driven power supplies whilst
potentially ever present in any electrical equipment, would be minimised by adherence
to good installation practice and thorough testing at the following stages:
a)
Original assembly.
b)
Commissioning.
c)
Regular intervals, thereafter.
All test equipment must be in good working order prior to its use. High current power supplies can be
dangerous because of the possibility of substantial arcing. Always switch off during disconnection and
reconnection.
2.3.
RF Radiation Hazard
RF radiation, (especially at UHF frequencies) arising from transmitter outputs
connected to AWL’s equipment, must be considered a safety hazard.
This condition might only occur in the event of cable disconnection, or because a
‘spare’ output has been left un-terminated. Either of these conditions would impair the
system’s efficiency. No investigation should be carried out until all RF power sources have been
removed. This would always be a wise precaution, despite the severe mismatch between the
impedance of an N type connector at 50Ω, and that of free space at 377Ω, which would severely
mitigate against the efficient radiation of RF power. Radio frequency burns could also be a hazard, if
any RF power carrying components were to be carelessly touched!
Antenna positions should be chosen to comply with requirements (both local & statutory) regarding
exposure of personnel to RF radiation. When connected to an antenna, the unit is capable of
producing RF field strengths, which may exceed guideline safe values especially if used with
antennas having appreciable gain. In this regard the use of directional antennas with backscreens
and a strict site rule that personnel must remain behind the screen while the RF power is on, is
strongly recommended.
Where the equipment is used near power lines or in association with temporary masts not having
lightning protection, the use of a safety earth connected to the case-earthing bolt is strongly advised.
2.4.
Lifting and other Health and Safety Recommendations
Certain items of AWL equipment are heavy and care should be taken when lifting them
by hand. Ensure that a suitable number of personnel, appropriate lifting apparatus
and appropriate personal protective equipment is used especially when installing Cell
Enhancers above ground e.g. on a mast or pole.

2.5.
Chemical Hazard
Beryllium Oxide, also known as Beryllium Monoxide, or Thermalox™, is sometimes
used in devices within equipment produced by Axell Wireless Ltd. Beryllium oxide dust
can be toxic if inhaled, leading to chronic respiratory problems. It is harmless if
ingested or by contact.
Products that contain beryllium are load terminations (dummy loads) and some power amplifiers.
These products can be identified by a yellow and black “skull and crossbones” danger symbol (shown
above). They are marked as hazardous in line with international regulations, but pose no threat under
normal circumstances. Only if a component containing beryllium oxide has suffered catastrophic
failure, or exploded, will there be any danger of the formation of dust. Any dust that has been created
will be contained within the equipment module as long as the module remains sealed. For this reason,
any module carrying the yellow and black danger sign should not be opened. If the equipment is
suspected of failure, or is at the end of its life-cycle, it must be returned to Axell Wireless Ltd. for
disposal.
To return such equipment, please contact the Operations Support Department, who will give you a
Returned Materials Authorisation (RMA) number. Please quote this number on the packing
documents, and on all correspondence relating to the shipment.
PolyTetraFluoroEthylene, (P.T.F.E.) and P.T.F.E. Composite Materials
Many modules/components in AWL equipment contain P.T.F.E. as part of the RF insulation barrier.
This material should never be heated to the point where smoke or fumes are evolved. Any person
feeling drowsy after coming into contact with P.T.F.E. especially dust or fumes should seek medical
attention.
2.6.
Laser Safety
General good working practices adapted from
EN60825-2: 2004/ EC 60825-2:2004
Do not stare with unprotected eyes or with any unapproved optical device at the fibre
ends or connector faces or point them at other people, Use only approved filtered or attenuating
viewing aids.
Any single or multiple fibre end or ends found not to be terminated (for example, matched, spliced)
shall be individually or collectively covered when not being worked on. They shall not be readily
visible and sharp ends shall not be exposed.
When using test cords, the optical power source shall be the last connected and the first
disconnected; use only approved methods for cleaning and preparing optical fibres and optical
connectors.
Always keep optical connectors covered to avoid physical damage and do not allow any dirt/foreign
material ingress on the optical connector bulkheads.
The optical fibre jumper cable maximum bend radius is 3cm; any smaller radii may result in optical
cable breakage or excessive transmission losses.
Caution: The FO units are NOT weather proof.

Tri-Band Cable Signal Combiner 60-214702
Tri-Band Combiner 60-214702 is built into a wall-mounted, environmentally protected (IP65)
aluminium alloy case; RF ports and connectors are also IP65 standard making the entire enclosure
and connecting ports weatherproof. The door is fitted with three locking door handles which also
serve to locate the door onto the case. Caution, the door is not attached to the case when the locking
door handles are opened.
The Combiner has connections for various RF inputs and outputs across three bands; AWS, PCN and
Cellular.
AWS and PCN Downlink signals are received from the operators’ base stations, filtered and combined
into a single path and then passed to local LCX antannas, a portion of the Downlink signal is tapped
off and fed to a fibre optic transmitter which modulates the RF signal onto a laser for transmission to
the Remote Repeater 60-214701 as optical signals over fibre optic cable.
AWS and PCN Uplink signals are received from the local LCX antannas, filtered and amplified before
being split into their respective band/frequency allocations and fed to the operators’ base stations.
Optical signals from the Remote Repeater 60-214701 are demodulated to RF and combined with the
Uplink signal from the LCX antennas after the amplification stages.
The Cellular signal path is in the Uplink direction only, Signals are received, filtered and amplified
before being fed to the operators’ base stations.
Warning! The door is not attached when unlocked

stations
3.1.
60-214702 features dual redundant amplification stages in the Uplink bands so that in case of any
single amplifier failure, complete signal loss would not occur in that path, allowing continued
coverage. It also has a comprehensive alarm system (each amplifier module carries its own voltagefree contact alarm relay output). 60-214702 is powered from an AC supply at 110V.
Caution must be exercised when attempting to move or lift this unit as the gross weight of the unit is in
excess of 90kg (200lbs)

PSU and Battery Backup 60-214703
PSU and Battery Backup 60-214703 is built into a wall-mounted, environmentally protected (IP65)
aluminium alloy case; ports and connectors are also IP65 standard making the entire enclosure and
connecting ports weatherproof. The door is fitted with locking door handles and handles are provided
for carrying the unit. There are Power On and Alarm indicators on the outside of the door.
The power supply uses two identical 400Watt mains driven PSU modules connected via power
combining diodes to supply 24V DC power to the Remote site equipment. This wiring arrangement
allows either of the modules to supply power continuously should one of the PSUs fail. Both the PSU
modules are alarmed through a 12V relay PCB and will activate the main alarm should either module
fail. Mains trip switches isolate the AC supply to either PSU module should either need to be switched
off.
The battery backup system operates in parallel with the main AC derived DC supply from the PSU
Modules; thus if the primary AC fails the backup system provides a seamless “no-break” transition
from mains to battery. Four 12V, 38Ah Sealed Lead-Acid batteries are employed, arranged in two
pairs wired in series each pair providing a 24V Output. Pair 1 provides backup for Remote Repeater
60-214701 and Pair 2 provides backup for existing PCS Amplifier 60-004001. During normal
operation the AC mains float charge the batteries via a third mains driven PSU Module.
A Low Voltage Disconnect circuit exists which cuts the battery power to the equipment when the
battery voltage falls below a pre-set threshold. A series regulator circuit ensures that the DC voltage
from the fully charged batteries does not exceed 12V per battery.
All PSU modules are separately alarmed and the summed alarm data is presented at the connector
labelled “N” in section 5.3.2. from where it is fed to Remote Repeater 60-214701 for onward
transmission to the Master Site

Installation – General Notes
6.1
General Remarks
When this equipment is initially commissioned, please use the equipment set-up record sheet in
Appendix B. This will help both the installation personnel and Axell Wireless should these figures be
needed for future reference or diagnosis.
The procedure for installing and commissioning an Axell Wall Mount Repeater is generally as follows:
Secure the Repeater in the chosen wall position.
Fix the antenna and connect its cables to the Repeater antenna ports.
Connect a suitable mains or battery power supply to the Repeater
Calculate the attenuation settings required for the uplink and the downlink paths, and set the
attenuators as described elsewhere in this document.
Switch the equipment mains on with the small switch located inside the Repeater on the lower
right hand side of the case.
If Base Station signals are available, make test calls via the Amplifier to ensure correct
operation, if possible monitoring the signal levels during these calls to ensure that the uplink
and downlink RF levels are as anticipated.
6.2
Electrical Connections
It is recommended that the electrical mains connection is made by a qualified electrician, who must be
satisfied that the supply will be the correct voltage and of sufficient capacity.
All electrical and RF connections should be completed and checked prior to power being applied for
the first time.
Ensure that connections are kept clean and are fully tightened.
6.3
RF Connections
Care must be taken to ensure that the correct connections are made with particular attention made to
the base station TX/RX ports. In the event that the base transmitter is connected to the RX output of
the equipment, damage to the equipment will be done if the base station transmitter is then keyed.
6.3.1. Termination of Unused Ports
In the event that any RF ports are unused (available for future expansion) these ports must be kept
terminated with the load terminations supplied by Axell for that purpose
Ensure that connections are kept clean and are fully tightened.
6.4
Optical Connections
The optical input and output ports will be shown in the system drawings. The ports are supplied with a
green plastic cover, which must be removed prior to the connection of the fibre cable. Ensure that
transmitter and receiver fibre cable are identified to prevent misconnection. At the master site, the
fibre transmitters are in the downlink path with the receivers in the uplink. At the remote sites the fibre
transmitters are in the uplink with the receivers in the downlink.
Always ensure that connections are kept clean and are fully tightened.

6.5
Commissioning
Once all connections are made the equipment is ready for commissioning.
To commission the system the test equipment detailed in Section 7.2. will be required.
Using the system diagrams and the end-to-end test specification (supplied with the equipment), the
equipment should be tested to ensure correct operation. Typical RF levels that are not listed in the
end-to-end specification, such as input levels to the fibre transmitters are detailed in the maintenance
section of this manual.
On initial power up the system alarm indicators on the front doors of the equipment should be
checked. A green LED on each unit with a power supply to it illuminates to indicate that the power
supply is connected to the unit. A red LED illuminated indicates a fault in that particular unit that must
be investigated before proceeding with the commissioning.
In the event that any part of the system does not function correctly as expected, check all connections
to ensure that they are to the correct port, that the interconnecting cables are not faulty and that they
are tightened. The majority of commissioning difficulties arise from problems with the interconnecting
cables and connectors.
6.6
Antenna Installation & Gain Calculations
The equipment typically requires two (or as appropriate) antennas, one a highly directional
Yagi or similar directed towards the donor cell base station, and one a leaky feeder, omnidirectional antenna or Yagi to cover the area in which the mobiles are to be served.
The maximum gain at which the equipment can be set is limited by the isolation that can be
achieved between these two antennas. Therefore when the antennas have been installed,
inject a signal (at a known power level) into one of them and measure the signal level received
by the other antenna on a spectrum analyser. The isolation can then be calculated as the
difference between these two figures. The gain in each path of the equipment should be set at
least 10 dB below this figure, using attenuators as described below in paragraph E.
Also measure the received signal from the donor cell at the input to the equipment (base port).
The gain of the equipment downlink path should be set such the donor site will not overload
the equipment amplifiers. It is recommended that the input level should be less than -50dBm
at the input of the equipment (Base Port). (This figure is assuming maximum gain, and may be
increased by the value of the attenuator fitted in the downlink path.)
Ensure that the mobile facing antenna has at least 70dB isolation from the nearest mobile.
(This is usually easily achieved when using a leaky feeder.)
The equipment gain is set by setting the variable switched attenuators in each path (uplink and
downlink) refer to the photographs and layout drawings for the exact attenuator locations).
Note that the uplink (mobile to base) and downlink (base to mobile) path gains are set
independently. This allows the paths to have different gains if required to set the correct output
power levels.
It is recommended that the gains are set such that the Downlink channel output levels from the
equipment are typically +30dBm per channel
(Input level + Gain = Output level).

Maintenance – General Notes
7.1.
Fault Finding
7.1.1.
Quick Fault Checklist
All tunnel equipment is individually tested to specification prior to despatch. Failure of this type of
equipment is not common. Experience has shown that a large number of fault conditions relating to
tunnel installations result from simple causes often occurring as result of transportation, unpacking
and installation. Below are listed some common problems which have resulted in poor performance or
an indicated non-functioning of the equipment.
•
•
•
•
•
•
•
•
•
•
Mains power not connected or not switched on.
External connectors not fitted or incorrectly fitted.
Internal connectors becoming loose due to transport vibration.
Wiring becoming detached as a result of heavy handling.
Input signals not present due to faults in the antenna and feeder system.
Base transmissions not present due to fault at the base station.
Modems fitted with incorrect software configuration.
Changes to channel frequencies and inhibiting channels.
Hand held radio equipment not set to repeater channels.
Hand held radio equipment not set to correct base station.
7.1.2
Fault Isolation
In the event that the performance of the system is suspect, a methodical and logical approach to the
problem will reveal the cause of the difficulty. The System consists of modules fitted in enclosed
shelves within a rack mounted, environmentally protected enclosure.
Transmissions from the main base stations are passed though the system to the mobile radio
equipment; this could be a handheld radio or a transceiver in a vehicle. This path is referred to as the
downlink. The return signal path from the mobile radio equipment to the base station is referred to as
the uplink.
The first operation is to check the alarms of each of the active units and determine that the power
supplies to the equipment are connected and active.
This can be achieved remotely (via CEMS, the RS232 Coverage Enhancement Management System,
if fitted), or locally with the front panel LED’s. The green LED on the front panel should be illuminated,
while the red alarm indicator should be off. If an Alarm is on, then that individual shelf must be
isolated and individually tested against the original test specification.
The individual amplifier units within the shelf have a green LED showing through a hole in their piggyback alarm board, which is illuminated if the unit is working correctly. If an amplifier is suspect, check
the DC power supply to the unit. If no other fault is apparent use a spectrum analyser to measure the
incoming signal level at the input and then after reconnecting the amplifier input, measure the output
level. Consult with the system diagram to determine the expected gain and compare result.
In the event that there are no alarms on and all units appear to be functioning it will be necessary to
test the system in a systematic manner to confirm correct operation.

7.1.3
Downlink
Confirm that there is a signal at the expected frequency and strength from the base station. If this is
not present then the fault may lay outside the system. To confirm this, inject a downlink frequency
signal from a known source at the master site BTS input and check for output at the remote site
feeder output.
If a signal is not received at the output it will be necessary to follow the downlink path through the
system to find a point at which the signal is lost. The expected downlink output for the given input can
be found in the end-to-end test specification.
7.1.4
Uplink
Testing the uplink involves a similar procedure to the downlink except that the frequencies used are
those transmitted by the mobile equipment.
7.1.5
Fibre Optics
The Fibre Optic transmitters and receivers both have two LED status indicators, one on each module
showing DC power and the other indicating ‘Laser On’ for the transmitter, and ‘Carrier Being
Received’ for the receiver. Assuming that all of the indicators are illuminated, it will be necessary to
check the RF inputs and outputs to the fibre optic units.
Typically the input to transmitter units will be at a level of between -30 and -15 dBm. The RF gain of a
pair (TX to RX) units is factory set to give a 0dB gain, but this is with a short, low loss fibre. In
determining the performance of the link, the insertion loss of the fibre and any power splitters fitted
must be considered. A general rule of thumb figure would be around 0.5 - 1.5dB loss per Kilometre.
7.1.7
Checking service
Following the repair of any part of the system it is recommended that a full end-to-end test is carried
out in accordance with the test specification and that the coverage is checked by survey.
It is important to bear in mind that the system includes a radiating cable network and base stations
that may be faulty or may have been damaged.
7.1.8
Fault repair
Once a faulty component has been identified, a decision must be made on the appropriate course to
carry out a repair. A competent engineer can quickly remedy typical faults such as faulty connections
or cables. The exceptions to this are cable assemblies connecting bandpass filter assemblies that are
manufactured to critical lengths to maintain a 50-ohm system.
Care should be taken when replacing cables or connectors to ensure that items are of the correct
specification. The repair of component modules such as amplifiers and bandpass filters will not
usually be possible in the field, as they frequently require specialist knowledge and test equipment to
ensure correct operation. It is recommended that items of this type are replaced with a spare unit and
the faulty unit returned to Axell Wireless for repair.

Care of Modules
7.3.1
General Comments
Many of the active modules contain semiconductor devices utilising MOS technology, which can be
damaged by electrostatic discharge. Correct handling of such modules is mandatory to ensure their
long-term reliability.
To prevent damage to a module, it must be withdrawn and inserted with care. The module may have
connectors on its underside, which might not be visible to the service operative.
7.3.2
Module Removal (LNAs, general procedure):
The following general instructions should be followed to remove a module:
Remove power to the unit
Remove all visible connectors (RF, DC & alarm)
Release module retaining screws.
Slowly but firmly, pull the module straight out of its position. Take care not to twist/turn the
module during withdrawal. (When the module is loose, care may be needed, as there may be
concealed connections underneath).

7.3.3
Module Replacement (general):
Carefully align the module into its location then slowly push the module directly straight into its
position, taking care not to twist/turn it during insertion.
Reconnect all connectors, RF, alarm, power etc., (concealed connectors may have to be
connected first).
Replace retaining screws (if any).
Double-check all connections before applying power.
7.3.4
Power Amplifiers
1)
Remove power to the unit. (Switch off at mains/battery, or remove DC in connector)
2)
Remove alarm wires from alarm screw terminal block or disconnect multi-way alarm
connector.
3)
Carefully disconnect the RF input and output coaxial connectors (usually SMA)
If alarm board removal is not required, go to step 5.
4)
There is (usually) a plate attached to the alarm board which fixes it to the amplifier, remove its
retaining screws and the alarm board can be withdrawn from the amplifier in its entirety. On
certain types of amplifier the alarm board is not mounted on a dedicated mounting plate; in this
case it will have to firstly be removed by unscrewing it from the mounting pillars, in most
cases, the pillars will not have to be removed before lifting the amplifier.
5)
If the amplifier to be removed has a heatsink attached, there may be several different ways it
can have been assembled. The most commonly used method, is screws through the front of
the heatsink to threaded screw holes (or nuts and bolts), into the amplifier within the main
case. If the heatsink is mounted on the rear of the main case (e.g., against a wall in the case
of wall mounted enclosures), then the fixing method for the heatsink will be from within the
case, (otherwise the enclosure would have to be removed from the wall in order to remove the
heatsink).
When the heatsink has been removed, the amplifier may be unscrewed from the main casing by its
four corner fixings and gently withdrawn.
Fitting a new power amplifier module will be the exact reverse of the above.
Note: Do not forget to apply fresh heatsink compound to the heatsink/main case joint and also
between the amplifier and the main case.

Note: Tighten SMA connectors using only a dedicated SMA torque spanner. If SMA connectors are
over-tightened, irreparable damage will occur. Do not use adjustable pliers to loosen/tighten SMA
connectors.
Also take care not to drop or knock the module as this can damage (or misalign in the case of tuned
passive modules) sensitive internal components. Always store the modules in an environmentally
friendly location
7.3.6
Module Transportation:
To maintain the operation, performance and reliability of any module it must be stored and
transported correctly. Any module not installed in a whole system must be kept in an anti-static bag or
container. These bags or containers are normally identified by being pink or black, and are often
marked with an ESD label. Any module sent back to Axell Wireless for investigation/repair must be so
protected. Please contact the Axell Wireless quality department before returning a module, see
section 2.7.

Waste Electrical and Electronic Equipment (WEEE) Notice
The Waste Electrical and Electronic Equipment (WEEE) Directive became law in
most EU countries during 2005. The directive applies to the disposal of waste
electrical and electronic equipment within the member states of the European
Union.
As part of the legislation, electrical and electronic equipment will feature the
crossed out wheeled bin symbol (see image at left) on the product or in the
documentation to show that these products must be disposed of in accordance
with the WEEE Directive.
In the European Union, this label indicates that this product should not be disposed of with domestic
or "ordinary" waste. It should be deposited at an appropriate facility to enable recovery and recycling.
