Part 1 – HardwarePart one of this manual describes the Allgon AR repeaters, i.e. thehardware.Part one includes Chapter 1 through Chapter 5.The OMT32 software is described in part two of the manual, starting withChapter 6, OMT32 Installation.ALLGON System AB AR Repeaters & OMT32 HardwareUser’s Manual VD202 90/EN Rev. 1A 1999-07
1. Safety Any personnel involved in installation, operation or service of the Allgonrepeaters must understand and obey the following:•Allgon repeaters are designed to receive and amplify signals from one ormore base stations and retransmit the signals to one or more mobilestations. Also, the repeaters are designed to receive signals from one ormore mobile stations, amplify and retransmit to the base stations. Therepeaters must be used exclusively for these purposes and nothing else.•Repeaters supplied from the mains must be connected to groundedoutlets and in conformity with any local regulations.•The power supply unit in repeaters supplied from the mains containsdangerous voltage level, which can cause electric shock. Switch themains off prior to any work in such a repeater. Any local regulationsare to be followed when servicing repeaters.Authorized service personnel only are allowed to service repeaters whilethe mains is switched on.•The repeater cover must be secured in opened position, e.g. by tying itup, at outdoor repeater work. Otherwise, the cover can be closed by thewind and cause your fingers getting pinched or your head being hit.•When working on a repeater on high ground, e.g. on a mast or pole, becareful not to drop parts or the entire repeater. Falling parts can causeserious personal injury.•Any repeater, including this repeater, will generate radio signals andthereby give rise to electromagnetic fields that may be hazardous to thehealth of any person who is extensively exposed to the signals at theimmediate proximity of the repeater and the repeater antennas.BERYLLIUM OXIDE•The CHA channel board power transistors, the PA amplifier boardpower transistors, and the combiners (CMB) contain beryllium oxide(BeO) that is poisonous if present as dust or smoke which can beinhaled. The power transistors mentioned are mounted with twoscrews as opposed to other transistors.Do not file, grind, machine, or treat these parts with acid.Warning signs are applied on boards and units that contain berylliumoxide. These warning signs are shown in the next section.HYDROGEN FLUORIDE•The coaxial cable insulation is made of PTFE, polytetrafluoro ethylene,that gives off small amounts of hydrogen fluoride when heated.Hydrogen fluoride is poisonous. Do not use heating tools whenstripping off coaxial cable insulation.No particular measures are to be taken in case of fire because theemitted concentration of hydrogen fluoride is very low.•A lithium battery is permanently mounted on the CU board.

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

Repeater Types The following repeater types are available:•Channel selective GSM repeater•Channel selective CDMA repeater•Band selective repeater with fixed band width•Band selective repeater with adjustable band width•Combined repeaterIn the OMT32, the channel selective 900, 1800, and 1900 systems arecalled GSM, DCS and PCS respectively, even though these systems mayhave different names in other parts of the world.Channel selective GSM repeaterA channel selective GSM repeater can be equipped with two, four, six oreight channels. This repeater type is used for channel selective systems,such as GSM, DCS/PCN and GSM 1900 (PCS).Channel selective CDMA repeaterA channel selective CDMA repeater can be equipped with one or twochannels. This repeater type is used for digital code division systems inaccordance with IS-95 or J-std-008 standard.Band selective repeater, fixed band widthA band selective repeater with fixed band width has fixed filters for acertain band width. This repeater type is used for analog or digitalsystems, such as NMT, TACS/ETACS, AMPS, DAMPS and CDMA.Band selective repeater, adjustable band widthA band selective repeater with adjustable band width has filters that canbe set to various band widths. This repeater type is used for analog ordigital systems, such as NMT, TACS/ETACS, AMPS, DAMPS and CDMA.Combined repeaterSome of the above mentioned types can be combined in the same repeaterchassis and be in operation in parallel.ALLGON System AB AR Repeaters & OMT32 Hardware – IntroductionUser’s Manual VD202 90/EN Rev. 1A 1999-07 2 - 2
Using RepeatersIn areas where the radio signal propagation is poor repeaters can be usedto fill out those areas which are not covered by the base station.The following scenarios are examples on this:-Sports arenas-Fair halls-Large shopping centres-Road and railway tunnels-Indoors in buildings with metal or concrete wallsOther examples where repeaters can be used to increase the coverage are:-Shaded areas-Fringe coverage areasIn areas where the traffic intensity is low, it is not cost efficient to installa base station. An Allgon repeater, which can be installed with aminimum of investments, is a much better solution. You save installationcosts as well as operational costs.Examples of using repeatersTwo examples are described in the following sections. An outdoor examplein a shaded valley and an indoor example in a sports arena.ALLGON System AB AR Repeaters & OMT32 Hardware – IntroductionUser’s Manual VD202 90/EN Rev. 1A 1999-07 2 - 3
Shaded Area A valley is shaded by hills. There is a base station 5 kilometers away, butthe lowest signal strength in the valley is less than –100dBm. A mastused for other purposes is available for a repeater installation. The mastheight is 42 meter and it is located on a hill. The scenario is illustratedin Figure 2-2.The donor antenna of the repeater was mounted at the top of the mastand the service antenna was mounted at the half mast.

3. InstallationBefore installation, read carefully Chapter 1, Safety.Siting the Repeater Allgon repeaters are designed for outdoor usage. However, humidity andtemperature changes may have affect on the reliability. A preferable sitefor the repeater is thus indoor, in a tempered and ventilated room.Sunshine If a repeater is placed outdoor and can be exposed to direct sunshine, it isessential that the air can circulate around the repeater with no obstacle.The operating temperature must not exceed +55°C due to sunshineexposure. A shelter must be used in this case.Shelter Allgon repeaters are designed with a weather proof outdoor case that canbe mounted without any kind of shelter from rain, snow or hail.If a repeater is to be opened on the site when raining, snowing, or hailingthere must be some kind of permanent or temporary shelter. This isapplicable to gentle rainfall, snowfall or hail. Limitations for very badweather is found in the next section.Allgon can provide a shelter designed for these repeaters. This shelter isshown in Figure 3-1.Outdoor Installation and Service Limitations Sited outdoors, the repeater must not be opened for installation orservice at bad weather, such as:-Intense rainfall, snowfall or hail-Storm or high wind-Extremely low or high temperature-High humidity of the airALLGON System AB AR Repeaters & OMT32 Hardware – InstallationUser’s Manual VD202 90/EN Rev. 1A 1999-07 3 - 1

Functional Description Allgon repeaters work as bi-directional on-frequency amplifiers.A repeater receives, amplifies, and retransmits signals downlink anduplink simultaneously, i.e. from the base station via the repeater to themobile stations and from the mobile stations via the repeater to the basestation.The repeater is connected to a BS antenna, directed towards the basestation, and to a MS antenna directed towards the area to be covered.These antennas are connected to the repeater with N type maleconnectors.To prevent instability due to poor antenna isolation, a built-in antennaisolation supervision feature reduces the gain level automatically whenpoor antenna isolation is detected.The Allgon repeaters are controlled by powerful microprocessors.Alarm and operational LEDs are visible on the repeater front.The repeater works with convection cooling without fan.Operational parameters such as gain, channel number, power levels, etc.are set using a desktop or notebook and the Allgon OMT32, whichcommunicate, locally or remotely via modem, with the repeater controlunit (CU). Remote operation is performed using a telephone line or abuilt-in mobile phone equipped with a data interface.ALLGON System AB AR Repeaters & OMT32 Hardware – Functional DescriptionUser’s Manual VD202 90/EN Rev. 1A 1999-07 5 - 1
Repeater Design The repeater is housed in a cast aluminium chassis that is waterproof,class IP65, for outdoor use. The chassis has a design suited for outdooruse as well as indoor use.The chassis consists of a cabinet and a cover joined with hinges. Thecabinet contains the repeater circuitry. The cover can either be a thincover or a large cover. The latter consists of another cabinet which canbe used as an empty cover or be equipped as an independent repeatersystem.The cover has two external LEDs for operation and alarm indication.The cabinet as well as a large cover can be equipped for channel selectiveoperation or band selective operation. A combined repeater is normallyequipped for channel selective operation in the cabinet and band selectiveoperation in the cover.Different amplifier boards are used to get the various operations (seebelow). The amplifier boards are individually shielded and located undermetal cover sheets which can be folded out.Channel selective GSM amplifier boardsChannel selective GSM repeaters can handle up to eight repeater channels(four if the CU part number is K103/1). For every even number ofrepeater channels, two CHA amplifier boards are required in the repeater,one CHA board for uplink signaling and one board for downlink signaling.Each repeater channel is allocated to a radio channel or switched off. In aGSM type TDMA system (GSM, EGSM, DCS1800 or PCS1900), onerepeater channel can handle eight calls (sixteen if half-rate encoding isused).Channel selective CDMA amplifier boardsCurrent CDMA repeaters can handle two CDMA repeater channels. Forevery even number of repeater channels, two CSA amplifier boards andtwo PA amplifier boards are required in the repeater, one pair of CSA/PAboards for uplink signaling and one pair for downlink signaling. Eachrepeater channel is allocated to a radio channel or switched off.Band selective amplifier boardsBand selective repeaters can handle one wide band repeater channel. Theband width is either fixed or adjustable (fixed for 900MHz repeaters only).A band selective repeater channel requires two BSA boards and two PAamplifier boards in the repeater. One pair of BSA/PA boards for uplinksignaling and one pair for downlink signaling.ALLGON System AB AR Repeaters & OMT32 Hardware – Functional DescriptionUser’s Manual VD202 90/EN Rev. 1A 1999-07 5 - 2

The CU board contains a microprocessor, main memory, flashmemory for the CU software, EEPROM memory for parameters, memoryfor the event log and statistics, a REFO reference oscillator, ports for localand remote communication, battery powered real-time clock, etc.The CU board is used to supervise and control operational parameterssuch as gain control, channel handling, etc. The CU takes care of alarmsand the event log, password and logon, and many other procedures.The CU is also a control interface when using an OMT32/PC or anOMS/PC locally or remotely via modem.The CU software can be downloaded from an OMT32/PC or OMS/PCeither locally or remotely via modem.The real-time clock on the CU board is used for alarm and for the eventlog.There are currently two CU board variants: K103/1 and K103/2.CU board and CU software part #sK103/1 CU board (old) CU board K103/1 can be run with the SA102 01/2 CU software. Thisboard can store one version of CU software. The repeater will alwaysboot on this software version.K103/2 CU board (current) CU board K103/2 can be run with either the old SA102 01/2 CU softwareor the current SA102 02/1 or SA102 02/2 CU software. This board canstore two versions of CU software, located in segment 1 and segment 2 ofthe flash memory as Application 1 and Application 2. The repeater willboot on that software which is set as Primary (description of Primaryapplication is found in the CU Revision Manager section in Chapter 10).Compatibility for CU boards and CU software is detailed in the nextsection.ConnectionThe CU board is connected to the DIA board via the P2 port.CautionA lithium battery is permanently mounted on the CU board. Due to therisk of explosion, this battery must not be removed from the board. Incase of battery malfunction, replace the CU board. The old CU board canbe sent to Allgon for repair.ALLGON System AB AR Repeaters & OMT32 Hardware – Functional DescriptionUser’s Manual VD202 90/EN Rev. 1A 1999-07 5 - 24

Used gain Actual momentary gain for the uplink and downlink transmission.The gain may differ from the setpoint value due to poor antenna isolation.An antenna isolation test feature regulates the gain as follows:-After powering up, resetting or updating, the gain is increased to13dB above the Control to level (see Figure 10-8).The purpose of this 13dB ’over-gain’ is to test if there is a 13dBantenna isolation margin. The gain increase can be seen in theControl to and Used gain fields.-If no instability due to poor antenna isolation is detected during theantenna isolation test, the gain is decreased to the Control to levelafter 30 sec.-If instability due to poor antenna isolation is detected during theantenna isolation test, the gain is decreased to a level 13dB below thelowest detected poor antenna isolation level (see Figure 10-9).Warning alarm is activated when instability is detected and Ceasingwhen the instability has ceased.-The decreased gain level is kept for the next 60 minutes. Then, anew antenna isolation margin test is performed.93dBControl to 80dBFigure 10-8. Antenna isolation margin testInstability 85dBControl to 80dB72dB60 min.Figure 10-9.

Output gain regulation is performed as soon as poor antenna isolation isdetected during operation.If instability due to poor antenna isolation is detected at the lowestoutput gain, the channel is blocked and BLOCK mode is indicated in thestatus window. Error alarm is activated when instability is detected andCeasing when the instability has ceased. A constant CW signal in the GSM frequency band is a ’jammer’ whichmay be harmful to the cellular system. A BTS might, in worst case, bedisabled. The Allgon repeaters detect, however, strong CW signals. If aconstant CW signal is detected (channel board test point Power 1 orPower 2 >27dBm), the channel is blocked and BLOCK mode is indicatedin the status window. Error alarm is activated when the channel isblocked and Ceasing when the blocking has ceased.Antenna isolation test and CW signal strength test are performed in theuplink path. Gain regulation is then performed for uplink as well asdownlink using the uplink levels. Antenna isolation test is a valuable feature to reveal isolationproblems when installing repeaters. Also, it is very useful whenmaking site specific repeater adjustments such as antennaconfiguration (i.e. donor and service antenna vertical and horizontalpositions, beam alignment, and gain). The antenna isolation test isalso useful to reveal other environmental problems that must beconsidered, e.g. reflections from buildings, masts, traffic, etc.After performing the antenna isolation test, set the repeater gain(Gain set to) to the value obtained (13dB under the instability level).The repeater will then work with a safe gain margin to avoidinstability.It is not recommended to use the repeater isolation test in aninstable environment to automatically and continuously adjust thegain from the gain set by the operator.ALLGON System AB AR Repeaters & OMT32 Software – Repeater OperationsUser’s Manual VD202 90/EN Rev. 1A 1999-07 10 - 17

Alarm Overview Alarms are states or events in the repeaters that are more or lessdetrimental to the repeater function. All alarms are classified in thefollowing levels depending on the extent of malfunction the alarms cause.Alarm LevelsNoneAn event that is not detrimental to the repeater performance. None alarms will never be reported. If no alarm is active, None isindicated e.g. in the operational status window.WarningAn alarm level that decreases the repeater performance somewhat.A Warning alarm is not a serious alarm. It can be caused by poorantenna isolation, low traffic activity, etc.ErrorAn event indicating that a part of the repeater is not functioning. AnError alarm is a serious alarm. It can be caused by a synthesizer fault,external alarm, etc.CriticalAn event that makes the entire repeater cease to function. A Criticalalarm is a very serious alarm. It can be caused by a mains breakdown,external alarm such as fire, etc.CeasingAn event that resets a previous alarm, i.e. the event when the cause ofthe alarm ceased. Ceasing is e.g. applicable to an antenna isolation alarm,which after some time can be ceased if poor antenna isolation is no longerdetected.Alarm indicationAlarms are indicated with a LED on the repeater front and can betransferred to a locally or remotely connected OMT32.The alarm LED indication is reset by a power failure.Combined repeaters indicate alarms for both the repeater units if analarm has been activated in either of the units.ALLGON System AB AR Repeaters & OMT32 Software – Alarms and EventsUser’s Manual VD202 90/EN Rev. 1A 1999-07 11 - 2
Internal and External Alarms There are a number of internal alarms and four external alarm inputs.The internal alarms have fixed alarm levels. They are listed onpage 11-14.The external alarm inputs, EAL1 - EAL4, can be configured for variousalarm levels and alarm purposes in the Alarm Configuration window(description on page 11-4). Some of the alarm input purposes aredescribed below.EAL1The EAL1 external alarm input can also be used for mains breakdownalarm. This is further detailed in the Mains Breakdown Relay section inChapter 3.EAL2The EAL2 external alarm input can also be used for battery backup alarm.EAL3The EAL3 external alarm input can also be used for fiber optics alarm,provided the Fiber Optic OMT software is used.EAL4The EAL4 external alarm input can also be used for an alarm which isactivated if the repeater door is open.External alarm CeasingThe external alarm inputs can be selected with or without Ceasing.•With ceasing, e.g. Warning w ceasing, means that activated alarms aswell as ceased alarms are reported to the OMT32. The latter asCeasing.•Without Ceasing, e.g. Warning w/o ceasing, means that an activatedalarm will be reported to the OMT32. When the cause of the alarm hasceased, the event is assigned the None level.ALLGON System AB AR Repeaters & OMT32 Software – Alarms and EventsUser’s Manual VD202 90/EN Rev. 1A 1999-07 11 - 3
