SAFETY CONSIDERATIONS 1.1 Earthing of Equipment Cell Enhancers 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. 1.2 Electric Shock Hazard Electrical shocks due to faulty mains driven power supplies. Whilst ever potentially present in any electrical equipment, such a condition would be minimised by quality installation practice and thorough testing at:
a) Original assembly b) Commissioning c) Regular intervals, thereafter. All test equipment to 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. H/book Number:-50-078001HBKM Issue No:-A Date:-02/09/2004 Page:-10 of 88 800MHz & VHF Cell Enhancers Maintenance Handbook 1.3 RF Radiation Hazard RF radiation, (especially at UHF frequencies) arising from transmitter outputs connected to AFLs 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 unterminated. Either of these conditions would impair the systems 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 50, and that of free space at 377, 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. H/book Number:-50-078001HBKM Issue No:-A Date:-02/09/2004 Page:-11 of 88 800MHz & VHF Cell Enhancers Maintenance Handbook 1.4 Chemical Hazard Beryllium Oxide, also known as Beryllium Monoxide, or Thermalox, is sometimes used in devices within equipment produced by Aerial Facilities 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 Aerial Facilities Ltd for disposal. To return such equipment, please contact the Quality 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 AFL 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. Emergency Contact Numbers 1.5 The AFL Quality Department can be contacted on:

OVERVIEW/SYSTEM DESCRIPTION The AFL Channel and/or Band Selective Cell Enhancers are 2-way on-band repeaters. Various models are available to cover frequency bands from 50MHz to 3000MHz. The principle sphere of applications is in urban areas where the topology is such that shadows occur in the propagation pattern (for example within large buildings, conference centres, road and rail tunnels, etc.) The frequency bands that are passed by the Cell Enhancer are set as per the specific customer requirements. AFL manufacture a wide range of Cell Enhancers, configured for each customer's specific requirements. Two basic physical variants are available, a rack mounted version to fit in a standard 19" rack and an environmentally sealed wall mounted version which requires no further enclosure. This system provides 800MHz Channelised (x 24) & VHF Simplex/Duplex coverage for the various concourses platforms and tunnels with a 12V battery backup service (for the 800MHz line amplifier) that will guarantee limited continued coverage in case of mains power failure. Each active module is alarm monitored with each shelf/ wall-case having a summary alarm with a visual alarm active indication and a door intrusion alarm included for the wall cases.

SUB-UNIT MODULES 5.1 Bandpass Filters (02-007201 & 01-002503) 5.1.1 Description The bandpass filters are multi-section designs with a bandwidth dependent upon the passband frequencies, (both tuned to customer requirements). The response shape is basically Chebyshev with a passband design ripple of 0.1dB. The filters are of slot coupled, folded combline design, and are carefully aligned during manufacture in order to optimise the insertion loss, VSWR and intermodulation characteristics of the unit. The tuned elements are silver-plated to reduce surface ohmic losses and maintain a good VSWR figure and 50 load at the input and output ports. Being passive devices, the bandpass filters should have an extremely long operational life and require no maintenance. Should a filter be suspect, it is usually most time efficient to replace the module rather than attempt repair or re-tuning. 5.1.2 Technical Specification (02-007201) PARAMETER SPECIFICATION Response Type Chebyshev Frequency Range:

They are specialist narrow-band 3 port devices, designed with rejection and power handling as the main criteria. Being passive devices, the hybrid couplers should be maintenance free over their entire lifetime and have an extremely high MTBF figure. It is not recommended that the top cover be removed or any of the internal components needlessly touched, since the original factory alignment/tuning would be extremely hard to reproduce in a field environment. 5.9.2 Technical Specification PARAMETER SPECIFICATION Frequency Range: 140-175 MHz Bandwidth: 10% of fo Insertion Loss: 3.5dB Rejection: -18dB Impedance: 50 V.S.W.R: 1.2:1 Input to input isolation: >20dB Connectors: Type N Standard Dimensions: 140 x 120 x 35mm Power rating: 50Watts Weight: 0.5kg H/book Number:-50-078001HBKM Issue No:-A Date:-02/09/2004 Page:-56 of 88 800MHz & VHF Cell Enhancers Maintenance Handbook 5.10 Crossband Coupler (07-005705) 5.10.1 Description The purpose of a crossband coupler is to either combine/split transmission signals from different parts of the frequency spectrum. The crossband coupler fitted here, is the means by which the separate VHF and UHF frequency band signals are mixed to form a composite RF signal. It basically comprises of a 3 port device, two filters, one a low pass the other a high pass, that are then mixed and fed to a common output. The couplers are built into a machined aluminium casing having a centre screening wall between the filter sections and lid secured by screws at frequent intervals over its perimeter to obtain a tight seal and to ensure linearity and stability of response. 5.10.2 Technical Specification PARAMETER Passband 250MHz: 70-250MHz 380MHz: 380-960MHz Power Rating: 50 Watts (CW) SPECIFICATION Number of Input ports: 2 Number of Output ports: 1 Insertion loss: 0.5 dB

They are formally known as directional couplers as they couple power from the RF mainline in one direction only. Various constructional techniques are used depending on the specification required. These include microstrip, stripline, coaxial cable and capacitive types. 5.11.2 Technical Specification PARAMETER SPECIFICATION Frequency range: 170 2200MHz Insertion Loss: <0.3dB Coupling level: -6dB Rejection: N/A Weight: <200gms Connectors: N type, female operation:

Were this not to be the case, two simultaneous transmissions could interfere to create intermodulation products, especially in the non-linear power amplifier output stages of the transmitters. Whilst this effect would not affect the intelligibility of the two original transmissions, a further two new transmissions would be created which could themselves cause interference to third party users. The ferrite isolator is a ferro-magnetic device, which has directional properties. In the forward direction, RF arriving at the input is passed to the output with minimal attenuation. In the reverse direction, RF arriving at the output due to reflected power from a badly matched load, or due to coupling with another transmitter, is routed into an RF load where it is absorbed. The isolator therefore functions to prevent reflected RF energy reaching the power amplifier where it could cause intermodulation products or premature device failure. 5.12.2 Technical Specification PARAMETER SPECIFICATION Frequency range: 150-300MHz Bandwidth (% of centre frequency): 2 Isolation: 35dB (typical) Insertion loss: 0.25dB (typical V.S.W.R: 1.15:1 (typical) Maximum power: 200Watts (per carrier) Connector: SMA Weight: 200gm (approximately) H/book Number:-50-078001HBKM Issue No:-A Date:-02/09/2004 Page:-59 of 88 800MHz & VHF Cell Enhancers Maintenance Handbook 5.13 Watt 0- -30dB & 0-15dB Variable Attenuators (10-000701 & 10-000901) 5.13.1 General Application In many practical applications for Cell Enhancers etc., the gain in each path is found to be excessive. Therefore, provision is made within the unit for the setting of attenuation in each path, to reduce the gain. 5.13.2 Switched Attenuators The AFL switched attenuators are available in two different types; 0 30dB in 2 dB steps, or 0 15dB in 1 dB steps. The attenuation is simply set using the four miniature toggle switches on the top of each unit. Each switch is clearly marked with the attenuation it provides, and the total attenuation in line is the sum of the values switched in. They are designed to maintain an accurate 50 impedance over their operating frequency at both input and output.

Class A circuitry is used throughout the units to ensure excellent linearity and extremely low noise over a very wide dynamic range. The active devices are very moderately rated to provide a long trouble-free working life. There are no adjustments on these amplifiers, and in the unlikely event of a failure, then the complete amplifier should be replaced. This amplifier features its own in-built alarm system which gives a volt-free relay contact type alarm that is easily integrated into the main alarm system. 5.14.2 Technical Specification (11-001202) PARAMETER SPECIFICATION Frequency range: 10 - 600MHz Bandwidth: 200MHz (as required, tuneable) 1dB Compression point: >+15 dBm 3rd order intercept: >+25dBm Gain: 20dB (typical) VSWR: better than 1.5:1 Noise figure: 3.5dB (typical) Connectors: SMA female Supply: 108mA @ 24V DC Temp. range: operational: -10C to +60C storage: -20C to +70C Weight: 0.4kg Size: 88.9 x 50.8 x 31.75 mm (case only) 5.14.3 Technical Specification (11-004802) PARAMETER Frequency Range:

It demonstrates a very high linearity and a very good input/output return loss. It has built in a Current Fault Alarm Function with a volt-free relay contact pair as its output. Its housing is an aluminium case (Alocrom 1200 finish) with SMA connectors for the RF input/output and a D-Type connector for the power supply and the Current Fault Alarm Function. These amplifiers have no user adjustments and in case of failure should only be replaced. 5.15.2 Technical Specification (12-018601, 5W) PARAMETER SPECIFICATION Frequency range: 800-960MHz Small signal gain: 30dB Gain flatness: 1.2dB I/O Return loss: >20dB 1dB compression point: 37dBm OIP3: 52dBm Supply voltage: 12V DC Supply current: 2.0Amps (Typical) Temperature range operational: -10C to +55C storage: -30C to +70C Weight: <2kg (no heatsink) 5.15.3 Technical Specification (12-018001, 10W) PARAMETER SPECIFICATION Frequency range: 800-960MHz Small signal gain: 30dB Gain flatness: 1.2dB I/O Return loss: >18dB 1dB compression point: 42.8dBm OIP3: 56dBm Supply voltage: 24V DC Supply current: 5.0Amps (Typical) operational: -10C to +55C storage: -30C to +70C Weight: <2kg (no heatsink) Temperature range H/book Number:-50-078001HBKM Issue No:-A Date:-02/09/2004 Page:-64 of 88 800MHz & VHF Cell Enhancers Maintenance Handbook 5.15.4 Technical Specification (12-018002, 20W) PARAMETER SPECIFICATION Frequency range: 800-960MHz Small signal gain: 30dB Gain flatness: 1.2dB I/O Return loss: >18dB 1dB compression point: 42.8dBm OIP3: 56dBm Supply voltage: 12V DC Supply current: 5.0Amps (Typical) operational: -10C to +55C storage: -30C to +70C Weight: <2kg (no heatsink) Temperature range 5.16 VHF 5Watt Power Amplifier (12-004902) 5.16.1 Description The power amplifier used is a triple stage solid-state low-noise amplifier. Class AB circuitry is used in the unit to ensure good linearity over a wide dynamic range. The three active devices are very moderately rated to provide a long trouble-free working life.

Any departure from normal bias conditions is a result of device failure, excess temperature, over-driving or oscillation
(excessive power). In normal operation, the Class A bias circuit of the amplifier develops a constant voltage of 1.20V across the collector current setting resistor. The Amplifier Alarm Board is a window comparator device, which is adjusted to sense a departure from this condition. Several different alarm outputs are provided to simplify interfacing, (Relay Contact, Open Collector, and TTL Logic Levels) The basic version of the Alarm Board (12-002801) monitors a single amplifier stage. A three-stage version (12-002201) is used on complex amplifiers where three separate comparators have their outputs logically combined to a common output stage. Failure of any one stage will activate the alarms. Note that the alarm board has a green Light Emitting Diode located near to the centre of the printed circuit board, which is illuminated on Good, and extinguished on Alarm. It is therefore a simple matter to identify an active module failure, by searching for an Alarm Board which has its green LED extinguished. A simple test of the alarm board is possible by shorting across the monitor inputs, pins 1 and 2, 3 and 4 or across pins 5 and 6. This last monitor input is inactive if the board has been converted to a two way alarm board. (Refer to relevant amplifier alarm wiring diagram.) 1) 2) 3) In systems using simplex channel switching, it is necessary to be able to distinguish between a normal switching operation and erroneous modes where faults in the detector circuitry may cause data errors but not necessarily fire the alarms. The simplex alarm board is designed to differentiate between normal and spurious switching signals There are two selectable link options on the three-way board:
LINK1 - Removed to convert to two-way alarm board. LINK2 - Removed to isolate 0V from chassis earth. The one way alarm board only has the 0V isolation link (LINK2) fitted.

The simplex alarm/mute board is designed to differentiate between normal and spurious switching signals for single or multiple stage amplifiers. 5.19 Simplex Controller PCB (12-002811) 5.19.1 Description The Simplex controller logic PCB monitors the receiver squelch output for a signal change and activates the supply switching for either the uplink or down link path accordingly. In normal operation, the low level Rx path is activated, and the associated Tx path is switched off. When a signal is detected by the Rx Squelch module, the Rx squelch output goes low
(0v), which triggers the controller logic PCB. The PCB mutes the power supply to the opposite path Rx LNAs and switches on the power to the output power stage. In order to prevent the power stage noise blocking the opposite paths low level receiver, the power amplifier is normally muted.

Typically it is used to derive 5, 8, 12 or 15V from a 24V input. The circuit is based upon a pair of LM257 series variable voltage regulators (LM2576, 12 &
15V & LM2575, 5V), which are each capable of supplying an absolute maximum of 1.5A output current. Note that at full output current, the dissipation of the device must remain within design limits, bearing in mind the voltage which is being dropped across it. The maximum allowable dissipation will also depend on the efficiency of the heatsink on which the device is mounted. 5.20.1 Technical Specification PARAMETER SPECIFICATION Operating Voltage: 21 27V DC Output Voltage: 12V & 12V (typical) Output Current: 1.0A (maximum per o/p) Temperature Range Connections: Screw Terminal Block operational: -10C to +60C storage -20C to +70C PCB Size: 85 x 63mm H/book Number:-50-078001HBKM Issue No:-A Date:-02/09/2004 Page:-69 of 88 800MHz & VHF Cell Enhancers Maintenance Handbook 5.21 Simplex Squelch & AF Module (17-002802) 5.21.1 Description The difference in signal levels between the paths means that the channel modules would latch onto any signal in the band rather than a signal at the desired channel frequency. This is achieved, in part, to having the de-sense module, (which is controlled by the Simplex Rx squelch unit), apply maximum attenuation (via an AGC attenuator unit) to the downlink path, when the uplink is active. 5.21.2 Technical Specification PARAMETER SPECIFICATION Frequency range: 80-260MHz Bandwidth: 20MHz (tuned to spec.)

This is generally fitted in the Uplink path (not usually needed in the downlink path, as the signal here is at an almost constant level), to avoid overloading the input amplifiers should a mobile be operated very close to the unit. The AFL wide dynamic range Automatic Gain Control system consists of two units, a detector/amplifier and an attenuator. The logarithmic detector/amplifier unit is inserted in the RF path on the output of the power amplifier, and the attenuator is situated in the RF path between the 1st and 2nd stages of amplification. Normally the attenuator is at minimum attenuation. The detector/amplifier unit monitors the RF level being delivered by the power amplifier, and when a certain threshold is reached it begins to increase the value of the attenuator to limit the RF output to the (factory set) threshold. Therefore overloading of the power amplifier is avoided. The factory set threshold is 1dB below the Enhancer 1dB compression point. Some adjustment of this AGC threshold level is possible, a 10dB range is mostly achieved. It is not recommended under any circumstances to adjust the AGC threshold to a level greater than the 1dB compression point as system degradation will occur. The detector comprises of a 50 transmission line with a logarithmic amplifier which samples a small portion of the mainline power. The sampled signal is amplified and fed to a conventional half wave diode rectifier, the output of which is a DC voltage logarithmically proportional to the RF input signal. This DC voltage is passed via an inverting DC amplifier with integrating characteristics, to the output, which drives the attenuation control line of the corresponding AGC attenuator. This unit is fitted at some earlier point in the RF circuit. For small signals, below AGC onset, the output control line will be close to 12V and the AGC attenuator will have minimum attenuation. As the signal level increases the control line voltage will fall, increasing the attenuator value and keeping the system output level at a constant value. The AGC onset level is adjusted by the choice of sampler resistor R1 and by the setting of potentiometer VR1, (factory set @ time of system test) do not adjust unless able to monitor subsequent RF levels. The attenuator comprises a 50 P.I.N diode, voltage-variable attenuator with a range of 3 to 30dB. The attenuation is controlled by a DC voltage which is derived from the associated AGC detector unit. Note that the log detector module is used with an associated controller board, in the duplex shelves for detecting the presence of signals to be muted/amplified.

For each Downlink and Uplink channel frequency, subtract the appropriate synthesiser offset frequency from the required operational frequency and record the resulting local oscillator frequencies. Divide each Downlink and Uplink local oscillator frequency by the synthesiser channel spacing and check that the result is an integer (ie: no remainder). If the synthesiser division ratio is not an integer value, check the required operational frequency and repeat the calculation checking for mistakes. Convert the required local oscillator frequency to synthesiser programming switch state patterns according to the following table. NOTE: Ensure that the correct column is used from the table below according to the synthesiser channel spacing of the particular channel modules fitted to the Cell Enhancer.

One channel selectivity module is required for each channel. The Channel Selectivity Module is an Up/Down frequency converter that mixes the incoming channel frequency with a synthesised local oscillator, so that it is down-converted to an Intermediate Frequency (IF) in the upper HF range. An eight pole crystal filter in the IF amplifier provides the required selectivity to define the operating passband of the Cell Enhancer to a single PMR channel. The same local oscillator then converts the selected IF signal back to the channel frequency. Selectivity is obtained from a fixed bandwidth block filter operating at an intermediate frequency (IF) in the low VHF range. This filter may be internal to the channel selectivity module (Crystal or SAW filter) or an externally mounted bandpass filter, (LC or Helical Resonator). Various IF bandwidths can therefore be accommodated. A synthesized Local Oscillator is employed in conjunction with high performance frequency mixers, to translate between the signal frequency and IF. The operating frequency of each channel selectivity module is set by the programming of channel selectivity module frequencies and is achieved digitally, via hard wired links, banks of DIP switches, or via an onboard RS232 control module, providing the ability to remotely set channel frequencies. Automatic Level Control (ALC) is provided within each channel selectivity module such that the output level is held constant for high level input signals. This feature prevents saturation of the output mixer and of the associated amplifiers. Alarms within the module inhibit the channel if the synthesised frequency is not locked. The synthesiser will not usually go out of lock unless a frequency far out of band is programmed. The channel selectivity module is extremely complex and, with the exception of channel frequency programming within the design bandwidth, it cannot be adjusted or repaired without extensive laboratory facilities and the necessary specialised personnel. If a fault is suspected with any channel selectivity module it should be tested by substitution and the complete, suspect module should then be returned to AFL for investigation.

It is equipped with two dual pole change-over relays RL1 and RL2, with completely isolated wiring, accessed via screw terminals. Both relays are provided with polarity protection diodes and diodes for suppressing the transients caused by "flywheel effect" which can destroy switching transistors or induce spikes on neighbouring circuits. Its common use is to amalgamate all the alarm signals into one, volts-free relay contact pair for the main alarm system. Note that the board is available for different voltages (12 or 24V) depending on the type of relays fitted at RL1 and RL2. 5.25.2 Technical Specification PARAMETER SPECIFICATION Operating voltage: 8 to 30V (floating earth) Alarm Threshold: Vcc - 1.20 volt +15%

When a pre-set value has been reached (usually 21.5V DC) the unit will disconnect the batteries to prevent a deep discharge state which, if allowed to continue, could irreparably damage the batteries, necessitating replacement. The units other function is to regulate the battery voltage to the cell enhancer equipment to 23.5V when in back-up mode (the terminal voltage of fully charged batteries is likely to be higher than 27V, and therefore potentially damaging to electronics in the system). 5.26.2 Technical Specification PARAMETER SPECIFICATION Operating voltage: 9-16V Low voltage cut-off point: 10.5V (factory set) Temperature range operation: -10C to +55C storage: -20C to +70C Weight: <1kg Size: 109.98 x 55.88mm 5.27 Crystal Filters (93-980109) 5.27.1 Description Crystal filters are fitted at the inputs and outputs of the simplex/duplex shelves (instead of bandpass filters) in order to maximise the excellent isolation and rejection characteristics of these narrow-band devices. It is easier to achieve close channel spacing using crystal filters, however, due to the increased insertion losses, higher gain amplification is needed when they are utilised. 5.28 IXFN170N10 Power Mos-Fet Module (94-030015) 5.28.1 Description This power module is simply a power MOS-FET transistor which is the series regulator for the main 24V DC battery output voltage rail. It is enabled/disabled from the discriminator module, (see section 5.2) has fast switch-off characteristics and a low forward volt drop. It is attached to a heatsink assembly mounted on the side of the case.

The heavy-duty diodes prevent any reverse current from flowing back to their source or the alternative supply rail. Combining diodes such as these will also be used if the equipment is to be powered from external back-up batteries. 5.30 15V Switch-Mode PSU (96-300054) 5.30.1 Description The power supply unit is a switched-mode type capable of supplying 15V DC at 27Amps continuously. The amplifiers in this unit will draw approximately 20-22Amps at 24V DC, so the PSU will be used conservatively ensuring a long operational lifetime. No routine maintenance of the PSU is required. If a fault is suspected, then the output voltage from the power supply may be measured on its output terminals. This is typically set to 15.2V. The adjustment potentiometer will be found close to the DC output terminals. All the PSUs used in AFL Cell Enhancers are capable of operation from either 110 or 220V nominal AC supplies. The line voltage is sensed automatically, so no adjustment or link setting is needed by the operator. 5.30.2 Technical Specification AC Input Supply:

This will help both the installation personnel and AFL should these figures be needed for future reference or diagnosis. 6.1.1 Rack Mounted Equipment Installation will be a matter of securing each shelf into its appropriate place in the rack cabinet, connecting all the cables (RF, DC and alarm) to their correct ports/connectors and system testing (at the customers discretion) to prove the original specification. Care should be exercised when moving the 8U chassis as the weight may surprise an operator. Power should not be applied until all connections have been double-checked and verified. 6.1.2 Wall Mounted Equipment The size and weight of the wall mounting enclosure(s) mean that they represent a significant weight hazard when fitting. In the interests of safety this should be done before any electrical, RF, or alarm connections are made. The equipment must be located on a perpendicular, flat surface that is made from a material suitable for bearing the weight of the whole assembly with attached cables. If the installer is in any doubt about the suitability of a site it is recommended that he consult with an appropriately qualified Structural Engineer. It is important in determining the location of the units that space is allowed for access to the front and underneath of the equipment. To enable maintenance to be carried out, the door must be able to open fully. The location should be served with a duct to allow the entry of cables into the equipment. 6.1.3 Electrical Connections The power supply is connected to the equipment via an IP65 connector located on the bottom or side surface. It is recommended that the connection is made by a qualified electrician, who must satisfy himself that the supply will be the correct voltage and of sufficient capacity. All electrical and RF connection should be completed and checked prior to power being applied for the first time. Ensure that connections are kept clean and are fully tightened.

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 rack, damage to the equipment will be done if the base station transmitter is then keyed. Again, ensure that connections are kept clean and are fully tightened. 6.2 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, the equipment should be tested to ensure correct operation. On initial power up the system alarm indicators on the front panels of the equipment should be checked. A red LED illuminated indicates a fault in an amplifier module that must be investigated before proceeding with the commissioning. A green LED on the door illuminates, to indicate that the power supply is connected and active. 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. Quick Fault Checklist 6.3 All AFL 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 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. Wiring becoming detached as a result of heavy handling. Base transmissions not present due to faults at the base station. Modems fitted with incorrect software configuration/and or PIN Ns. Changes to channel frequencies and inhibiting channels. Hand held radio equipment not correctly set to repeater channels. Hand held radio equipment not correctly set to base station. Input signals not present due to faults in the aerial and feeder system. Internal connectors/ports becoming loose due to transport vibration. H/book Number:-50-078001HBKM Issue No:-A Date:-02/09/2004 Page:-82 of 88 800MHz & VHF Cell Enhancers Maintenance Handbook 7. MAINTENANCE 7.1 General Procedures 7.1.1 Basic Fault Finding 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 within an 8U shelf and housed within a standard 19 rack type cabinet. 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 LEDs. 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 module must be isolated and individually tested against the original test specification. The amplifier units within the shelf have a green LED showing through a hole in their cover, 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. H/book Number:-50-078001HBKM Issue No:-A Date:-02/09/2004 Page:-83 of 88 800MHz & VHF Cell Enhancers Maintenance Handbook 7.1.2 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. 7.1.3 Uplink Testing the uplink involves a similar procedure to the downlink except that the frequencies used are those transmitted by the mobile equipment. 7.1.4 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 AFL for repair. H/book Number:-50-078001HBKM Issue No:-A Date:-02/09/2004 Page:-84 of 88 800MHz & VHF Cell Enhancers Maintenance Handbook 7.1.5 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. 7.1.6 Service Support Advice and assistance with maintaining and servicing this system are available by contacting Aerial Facilities Ltd. 7.2 Tools & Test Equipment The minimum tools and test equipment needed to successfully service this AFL product are as follows:-

Correct handling of such modules is mandatory to ensure their long-term reliability. To prevent damage to a module, it must be withdrawn/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 rules should be followed to remove a module:
1 Remove power to the unit 2 Remove all visible connectors (RF, DC & alarm) 3 Release module retaining screws. 4 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):
1 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. 2 Reconnect all connectors, RF, alarm, power etc.,(concealed connectors may have to be connected first). 3 Replace retaining screws (if any). 4 Double-check all connections before applying power. 7.3.4 Power Amplifiers 1) Remove power to the unit. (Switch off @ 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 not have to be removed before lifting the amplifier. H/book Number:-50-078001HBKM Issue No:-A Date:-02/09/2004 Page:-86 of 88 800MHz & VHF Cell Enhancers Maintenance Handbook 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. 7.3.5 Low Power Amplifier Replacement 1 Disconnect the mains power supply and disconnect the 24V dc supply connector for the LPA. 2 Disconnect the RF input and output cables from the LPA. 3 Disconnect the alarm connector. 4 Remove the alarm monitoring wires from (D type connector) pins 9 and 10. 5 Remove the LPA module by removing the four retaining screws, replace with a new 6 Connect the RF cables to the LPA input and output connectors. Reconnect the wires to LPA module and secure it with the screws. the alarm board connector pins 9 and 10. 7 Reconnect the DC supply connector and turn the mains switch on. 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 AFL for investigation/repair must be so protected. Please contact AFLs quality department before returning a module.
