SAFETY CONSIDERATIONS 1.1 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. 1.2 RF Radiation Hazard “CAUTION: This equipment is approved for antennas mounted on fixed outdoor permanent structures. A minimum separation distance of 2 metres must be maintained between the radiating elements and any nearby persons. A maximum antenna gain of 21 dBi may be used. Operating this equipment without regard to these restrictions will result in RF exposure levels above the limits allowed by FCC rules.” This equipment complies with part 90 of the FCC rules. Any changes or modifications not expressly approved by the manufacturer could void the user’s authority to operate the equipment. 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. RF radiation, (especially at UHF frequencies) arising from transmitter outputs connected to AFL’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 unterminated. 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! 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. PBL UHF1/1A 1 & 2 Air Interface Maintenance Handbook H/book Number:-60-055900HBKM Issue No:-2 Date:-20/10/2003 Page:-9 of 85 1.3 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. PBL UHF1/1A 1 & 2 Air Interface Maintenance Handbook H/book Number:-60-055900HBKM Issue No:-2 Date:-20/10/2003 Page:-10 of 85 1.4 Laser safety General good working practices adapted from EN60825-2: 1994 “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 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: Do not get them wet, the FO units are NOT weather proof. 1.5 Emergency Contact Numbers The AFL Quality Department can be contacted on: Telephone Fax e-mail +44 (0)1494 777000 +44 (0)1494 777002 qa@aerial.co.uk PBL UHF1/1A 1 & 2 Air Interface Maintenance Handbook H/book Number:-60-055900HBKM Issue No:-2 Date:-20/10/2003 Page:-11 of 85 2. OVERVIEW/SYSTEM DESCRIPTION The AFL Off air Amplifiers for the Pasadena Blue line project are 2 way on-band RF amplifiers. Their application is as an interface between the donor radio sites and the Fibre optic receivers and transmitters which will extend coverage to the locations via the fibre optic link. There are two units one designated for the ‘UHF1’ frequencies the other for the ‘UHF2’ frequencies. Each unit is housed in an environmentally protected IP65 steel wall-mount case. Handles are provided for carrying the unit and the door is fitted with locks. The unit interfaces with ‘N’ type female connectors for RF connections and heavy duty connectors for routing of AC power supply input and alarm output wiring. Cable glands are provided for routing of the Fibre optic cable in to the unit. To provide adequate selectivity in the Downlink and Uplink paths, combline design bandpass quadplexers and duplexers are used at the air interface ports. In addition each channel to be passed is selected by a 15kHz or 25KHz Channel module which provides a high level of rejection at adjacent channels. To provide the required gain to reach the required signal levels, low-noise amplifiers (LNA’s) are used in each path, these being followed by power amplifier modules in the uplink to provide the required intermodulation performance. Gain adjustment is available locally using switched attenuators. Note that “Downlink” refers to the RF path from the base station (donor site) to the FO transmitter and that “Uplink” refers to the RF path from the FO receiver to the remote base station.

SUB-UNIT MODULES UHF 1 Air Interface (60-055901) 5.1 5.1.1 5.1.1.1 Bandpass Duplexers (02-013401) 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 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 50Ω load at the input and output ports. Note that the same filter is used for both UHF 1 & 2, but tuned differently depending on the required frequencies and bandwidth for each air interface. 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. No adjustments should be attempted without full network sweep analysis facilities to monitor both insertion loss and VSWR simultaneously. 5.1.1.2 Technical Specification PARAMETER Passband: FILTER 1 FILTER 2 Insertion Loss: FILTER 1 FILTER 2 Rejection: FILTER 1 SPECIFICATION 483.2-483.6 MHz 486.2-486.6 MHz 2.7 dB typical 2.7 dB typical 483.2-483.6 MHz > 80 dB FILTER 2 486.2-486.6 MHz > 80 dB Power Rating: Impedance: VSWR: Connectors: 250 Watt 50 ohm Better than 1.2:1 SMA female PBL UHF1/1A 1 & 2 Air Interface Maintenance Handbook H/book Number:-60-055900HBKM Issue No:-2 Date:-20/10/2003 Page:-30 of 85 5.1.2 5.1.2.1 2 & 4 Way UHF Splitters (05-002603 & 05-003401) Description The Splitter/Combiners used are UHF (300-500MHz) devices for accurately matching two or more RF signals to single or multiple ports, whilst maintaining an accurate 50Ω load to all inputs/outputs and ensuring that the VSWR and insertion losses are kept to a minimum. Any unused ports will be terminated with an appropriate 50Ω load. 5.1.2.2 Technical Specification (05-002603) PARAMETER Frequency Range: Bandwidth: Inputs: Outputs: Insertion Loss: Isolation: Return Loss (VSWR) – Input: Return Loss (VSWR) – Output: Impedance: Power Rating – Splitter: Power Rating – Combiner: Connectors: Size: Weight: 5.1.2.3 SPECIFICATION 380 - 520 MHz 140 MHz 3.5 dB (typical) >18 dB Better than 1.3:1 Better than 1.3:1 50 ς 20 Watts 0.5 Watt SMA female 54 x 44 x 21 mm (including connectors) 200 g Technical Specification 05-003401 PARAMETER Frequency range: Bandwidth: Rejection: Insertion loss: Connectors: Weight: operational Temperature range: storage SPECIFICATION 70 – 250MHz 180MHz >14dB (in band) SMA <1.5Kgm -10ΒC to +55ΒC -40ΒC to +70ΒC PBL UHF1/1A 1 & 2 Air Interface Maintenance Handbook H/book Number:-60-055900HBKM Issue No:-2 Date:-20/10/2003 Page:-31 of 85 5.1.3 ¼Watt 0- -30dB Switched Attenuator (10-000701) 5.1.3.1 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. 5.1.3.2 Switched Attenuators The AFL switched attenuators are available in two different types; 0 – 30dB in 2 dB steps (as in this case), 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 50Ω impedance over their operating 5.1.4 Low Noise Amplifiers (11-006102, 11-007302 & 11-007402) 5.1.4.1 General Description The low noise amplifiers used are double or single stage solid-state low-noise amplifiers. Class A circuitry is used in the units to ensure excellent linearity over a very wide dynamic range. The active devices are very moderately rated to provide a long troublefree working life. There are no adjustments on these amplifiers, and in the unlikely event of failure then the entire amplifier should be replaced. Note that all three amplifiers use similar DC power circuit boards. 5.1.4.2 Technical Specification (11-006102) PARAMETER Frequency range: Bandwidth: Gain: 1dB Compression Point: 3rd order intercept: Input return loss: Output return loss: VSWR: Noise figure: Connectors: Supply: operational: Temperature range: storage: Weight: SPECIFICATION 70 – 500MHz <430MHz 15.5dB (typical) +31dBm (typical) +46dBm (typical) >20dB >20dB Better than 1.5:1 <4.8dB SMA female 530mA @ 10 to 24V DC (typical) -10°C to +60°C -40°C to +70°C 260gms PBL UHF1/1A 1 & 2 Air Interface Maintenance Handbook H/book Number:-60-055900HBKM Issue No:-2 Date:-20/10/2003 Page:-32 of 85 H/book Number:-60-055900HBKM Issue No:-2 Date:-20/10/2003 11-006102 380-500MHz 1W 12-24vDC ******** **/**/20** OR 0086 AFL 19 OUT 34 IN 4 PLACES see note 2 28 see note 2 31 CHKD PBL UHF1/1A 1 & 2 Air Interface Maintenance Handbook Page:-33 of 85 APPD 22/03/02 DATE ALL DIMENSIONS ARE IN mm UNLESS OTHERWISE STATED MNR DRAWN NO DECIMAL PLACE ± 1mm ONE DECIMAL PLACE ± 0.3mm TWO DECIMAL PLACES ± 0.1mm TOLERANCES SCALE THIS IS A PROPRIETARY DESIGN OF AERIAL FACILITIES LTD.

All the semi-conductor devices are very conservatively rated to ensure low device junction temperatures and a long, trouble free working lifetime. The power amplifier should require no maintenance over its operating life. Under no circumstances should the cover be removed or the side adjustments disturbed unless it is certain that the amplifier has failed; since it is critically aligned during manufacture and any re-alignment will require extensive test equipment. 5.1.5.2 Technical Specification PARAMETER Frequency Range: Bandwidth: Maximum Output Power: Gain: 3rd Order Intercept Point: 1dB Compression Point: VSWR: Connectors: Supply: operational: Temperature range: storage: Size: Weight: SPECIFICATION 400 - 500MHz (tuned to spec.) 20MHz (typical, tuneable) >5W 30dB <+37dBm <+48dBm better than 1.45:1 SMA female 1.25A @ 24V DC -10°C to +55°C -40°C to +70°C 276 x 78 x 40mm (case only) 1.5 kg (excluding heatsink) PBL UHF1/1A 1 & 2 Air Interface Maintenance Handbook H/book Number:-60-055900HBKM Issue No:-2 Date:-20/10/2003 Page:-45 of 85 H/book Number:-60-055900HBKM Issue No:-2 Date:-20/10/2003 PBL UHF1/1A 1 & 2 Air Interface Maintenance Handbook Page:-46 of 85 IS S UE CR0521 PRODUCTION ISSUE DE S CRIP TI ON PRODUCTION ISSUE (CR0962) 2A No TITLE EDITED 2B DATE 16/9/92 27/1/94 23/12/98 08/11/01 DBS DJL SEW TAS CHK D DRA WN L1 L2 15 FB 2 C5 R E G1 APPD 14/09/92 DA TE 21 C6 L6 C7 15 15 L5 23 18 L4 FB 4 R2 C 13 NO DE CIMA L P LA CE ± 1mm ONE DE CIMA L P LA CE ± 0. 3mm TWO DE CI MAL P LACE S ± 0.1mm TOLE RA NCE S SCA LE TR 2 1:1 C 12 L3 FB 3 C 10 23 24 18 20 C8 C9 24V D C I NP U T 16 26 19 Fax (0494)764838 Little Chalfont(0494)763636 England Aerial Facilities Ltd OU TP U T IN 2 PLACES COMPLETE ALL SOLDERING USING ITEM FIT WITH CHAMFERED TAB IN DIRECTION SHOWN --> 14 C 11 R E G2 2 P0SNS PLAN VIEW WITH LID REMOVED THIRD ANGLE PROJECTION THIS IS A P ROP RIE TA RY DE S IGN OF A E RIA L FA CILITI E S LTD.

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) Volt-free change over relay contacts. Open collector NPN transistor pulls low on alarm. TTL driver. The use of precision voltage sources and resistors has eliminated the need for initial adjustment or calibration, and the board will function correctly with a wide variation in power supply voltage (8 to 30 volts, nominal supply is 12 or 24Volts). 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 circuit is basically an O.E.M semiconductor regulator (one side of which has a heatsink mounting plate, that is usually bolted to the casing of a Cell Enhancer) and smoothing components built onto a printed circuit board with screw block terminations. Note: no circuit diagram of the O.E.M. regulator is available. This unit should not be repaired, only replaced. 5.1.7.2 Technical Specification PARAMETER Input Voltage Range: Output Voltage: Max.

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. It’s 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. The single relay board (80-008902) is electrically identical to the dual version but is proportionately smaller in size. It also has a single in-line IDC connector in place of the screw terminal blocks of the dual model and performs similar summary alarm functions.

In this case the splitter/combiner module has one of its ports terminated (both uplink & downlink) with an appropriate load in order to preserve the correct impedance of the device over the specified frequency range. This has the advantage of allowing future expansion capability should extra channels or other functions become necessary. Terminations are available for every type of RF connector that may be used, N type, 7/16th or SMA, in this case SMA. 5.1.11 24V 400W Flat-Pack Power Supply (96-300011) 5.1.11.1 Description The power supply unit is a switched-mode type capable of supplying 24V DC at 16.0Amps continuously. Equipment of this type typically requires approximately 10.0 Amps 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 24.5V. All the PSU’s 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. No drawings of the PSU are available. 5.1.11.2 Technical Specification AC Input Supply: Voltage: 110 or 220V nominal - 90 to 132 or 180 to 264V (single phase, absolute limits) Frequency: 47 to 63Hz DC Output Supply: Voltage: 24V DC (nominal), 22 to 26V (absolute limits) Current: 16.0A Temperature operational: -10ΒC to +55ΒC range: storage: -40ΒC to +70ΒC PBL UHF1/1A 1 & 2 Air Interface Maintenance Handbook H/book Number:-60-055900HBKM Issue No:-2 Date:-20/10/2003 Page:-66 of 85 5.2 UHF 2 Air Interface (60-055902) 5.2.1 Bandpass Filter (02-013401) See section 5.1.1 5.2.2 4 Port Tx Hybrid Combiner (05-003019) 5.2.2.1 Description The 3dB Hybrid Combiner used is a device for accurately matching two or more RF signals to single or multiple ports, whilst maintaining an accurate 50Ω load to all inputs/outputs and ensuring that the VSWR and insertion losses are kept to a minimum. Any unused ports will be terminated with an appropriate 50Ω load. In UHF 2 this hybrid is used to combine the signals from the channel selective modules (from both UHF 1 & 2) in the downlink direction for onward transmission by fibre, and similar signals for both UHF 1 & 2 are combined before being further split into the uplink channel modules. 5.2.2.2 Technical Specification PARAMETER Frequency Range: Bandwidth: Inputs: Outputs: Insertion Loss: Isolation between Input or Output ports: Return Loss (VSWR) – Input: Return Loss (VSWR) – Output: Impedance: operation: Temperature Range storage: MTBF: Power Rating – Splitter: Power Rating – Combiner: Environmental: Connectors: Dimensions: Weight: SPECIFICATION ƒo ± 10% (50 – 500 MHz) ƒo ± 10% <3.5 dB >27 dB 1.3:1 1.3:1 50 Ω -10°C to +55°C -20°C to +70°C >180,000 hours Up to 150 Watts (load dependant) Available up to 100 Watts IP54 ‘N’ female 118 x 102 x 35 mm (including connectors) 0.5 kg PBL UHF1/1A 1 & 2 Air Interface Maintenance Handbook H/book Number:-60-055900HBKM Issue No:-2 Date:-20/10/2003 Page:-67 of 85 5.2.3 Four Way Low Power Splitter (05-003401) See section 5.1.2 5.2.4 ¼Watt 0- -30dB Switched Attenuator (10-000701) See section 5.1.3 5.2.5 Low Noise Amplifiers (11-007302 & 11-007402) See section 5.1.4 5.2.6 3 Stage Amplifier Alarm Boards (12-002201) See section 5.1.6 5.2.7 20Watt Power Amplifier (12-004201) 5.2.7.1 Description The power amplifiers fitted to this unit are multi-stage, solid state power amplifiers. Class A circuitry is employed throughout the units to ensure excellent linearity over a wide dynamic frequency range. All the semi-conductor devices are very conservatively rated to ensure low device junction temperatures and a long, trouble free working lifetime. The power amplifiers should require no maintenance over their operating lives. Under no circumstances should the cover be removed or the side adjustments disturbed unless it is certain that an amplifier has failed; since they are critically aligned during manufacture and any re-alignment will require extensive test equipment. 5.2.7.2 Technical Specification PARAMETER Frequency Range: Bandwidth: Maximum Output Power: Gain: 1dB Compression Point: 3rd Order Intercept Point: VSWR: Connectors: Supply: Size: Weight: Temperature operational: range: storage: SPECIFICATION 350 – 550MHz (tuned to spec.) 20MHz (tuned to spec.) >20W 30dB <+43dBm <+54dBm better than 1.45:1 SMA female 3.50A @ 24V DC 276 x 78 x 40mm (ex. connectors & heatsink) 1.5 kg (approximately, excluding heatsink) -10°C to +55°C -40°C to +70°C PBL UHF1/1A 1 & 2 Air Interface Maintenance Handbook H/book Number:-60-055900HBKM Issue No:-2 Date:-20/10/2003 Page:-68 of 85 5.2.7.3 Drg.

This PSU is used to provide power for the fibre optic modules which will typically require approximately 3.0 Amps 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 24.5V. All the PSU’s 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. 5.2.14.2 Technical Specification Voltage: Frequency: Voltage: Current: AC Input Supply: 110 or 220V nominal 90 to 132 or 180 to 264V (absolute limits) 47 to 63Hz DC Output Supply: 24V DC (nominal) 22 to 26V (absolute limits) 6.25A PBL UHF1/1A 1 & 2 Air Interface Maintenance Handbook H/book Number:-60-055900HBKM Issue No:-2 Date:-20/10/2003 Page:-74 of 85 5.2.15 Single Mode Optical Coupler (98-100001) 5.2.15.1 Description Single or dual optical couplers are used whenever it is required to split optical signals for transmission to more than one destination or combine them to a single common input. The couplers are O.E.M devices and are not considered repairable. Any suspected faulty coupler should be replaced. 5.2.16. Fibre Optic Receiver & Transmitter (98-200003 & 98-300003) 5.2.16.1 Description The F/O units consist of a receiver & transmitter, which modulates the RF signal onto a laser carrier and transmits it via fibre/optic cable to a receiver unit some distance away where it is demodulated back to the original RF signal with very small values of accrued attenuation. Both transmitter and receiver modules have their own dedicated alarm outputs (volt-free relay contacts) which are integrated into the main alarm system. Being O.E.M devices, no drawings or circuit diagrams are available. Caution: The FO units are NOT weather proof.

INSTALLATION 6.1 Initial Installation Record When this equipment is initially commissioned, please use the equipment set-up record sheet in Appendix A. This will help both the installation personnel and AFL should these figures be needed for future reference or diagnosis. 6.2 General The size and weight of the wall units mean that they represent a significant health hazard unless they are mechanically installed in the correct manner. In the interests of safety this should be done before any electrical, RF, or optical connections are made. It is important in determining the location of the wall 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 fully open. The location must be served with a duct to allow the entry of cables into the unit. 6.3 Electrical Connections The mains power supply and the alarms are connected through an IP65 connector which should need no further attention once connected. It is recommended that the AC power connection is approved 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. 6.4 Optical Connections The optical input and output ports are be located on a bracket fixed to the lower inside of the case. The optical fibres from the tunnels enter through a cable gland on the case underside 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. Where some of the fibre optic transmitter outputs are split with optical couplers to provide a connection to more than one remote site, care must be taken to ensure that the correct connections are made. Ensure that connections are kept clean and are fully tightened. PBL UHF1/1A 1 & 2 Air Interface Maintenance Handbook H/book Number:-60-055900HBKM Issue No:-2 Date:-20/10/2003 Page:-78 of 85 6.5 RF Connections All RF connections are made to the cable termination, located on the right-hand side of the wall enclosure. 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 may be done if the base station transmitter is then keyed. If the environment where the equipment is installed is deemed to be ‘wet’ i.e. water seepage through roofs or walls, then suitable methods to seal the RF N type connectors should be used, for example self amalgamating sealant tape. Ensure that connections are kept clean and are fully tightened. 6.6 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, 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 whole system diagram in section 4. On initial power up the system alarm indicators on the door of the equipment should be checked. A red LED illuminated indicates a fault and that particular module must be investigated before proceeding with the commissioning. A green LED illuminates, to indicate that the power supply is connected and valid. The individual fibre optic units are fitted with a pair of status indicators on their front panels. One is a green LED, which indicates that the unit is connected to a 15 Volt power supply. This indicator is common to both transmit and receive units. The second LED on the transmitter indicates that the laser is operating. On the receive unit the second LED indicates that a light signal is being received. When all the fibre connections are completed and power to each site is connected each fibre unit should show two illuminated indicators. 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.

MAINTENANCE 7.1 7.1.1 General Procedures 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 within a wall 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 walkie-talkie, mobile telephone 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 (optional) 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 digital RS232 Cell Enhancer Management System, if fitted), or locally with the front door LED’s. The green LED on the front door should be illuminated, while the red alarm indicator should be off. If an Alarm is on, then that individual module must be removed and tested against the original test specification. The individual amplifier units have a green LED showing through a hole in their piggy-back alarm board (or directly through a hole in the amplifier lid), 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 and amplifier specification 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 logical manner to confirm correct operation. PBL UHF1/1A 1 & 2 Air Interface Maintenance Handbook H/book Number:-60-055900HBKM Issue No:-2 Date:-20/10/2003 Page:-80 of 85 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, tuned cavities or 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. If spare parts need to be ordered from AFL, be sure to quote the serial number of the Cell Enhancer/Repeater and the serial number [and frequencies] of the module(s) to be replaced. PBL UHF1/1A 1 & 2 Air Interface Maintenance Handbook H/book Number:-60-055900HBKM Issue No:-2 Date:-20/10/2003 Page:-81 of 85 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:Spectrum analyser: Signal Generator: Attenuator: Test Antenna: Optical power meter: Digital multi-meter: Test cable x 2: Test cable x 2: Hand tools: 100kHz to 2GHz (Dynamic range = 90dB). 30MHz to 2GHz (-120dBm to 0dBm o/p level). 20dB, 10W, DC-2GHz, (N male – N female).

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 (LNA’s, general procedure): The following general rules 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 @ 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. PBL UHF1/1A 1 & 2 Air Interface Maintenance Handbook H/book Number:-60-055900HBKM Issue No:-2 Date:-20/10/2003 Page:-83 of 85 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 Disconnect the mains power supply and disconnect the 24V dc supply connector for the LPA. Disconnect the RF input and output cables from the LPA. Disconnect the alarm connector. Remove the alarm monitoring wires from (D type connector) pins 9 and 10. Remove the LPA module by removing the four retaining screws, replace with a new LPA module and secure it with the screws. Connect the RF cables to the LPA input and output connectors. Reconnect the wires to the alarm board connector pins 9 and 10. 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 antistatic 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 AFL’s quality department before returning a module.
