User’s manual for Repeater MRx01B PowerM0079A1A.doc Id.-No. 151775 Page 11 10-March-001 Introduction1.1 Intended purposeCellular telephone systems transmit signals in two directions between base stations andmobile telephones within the signal coverage area.If weak signal transmissions occur within the coverage area because of indoor applications,topological conditions or distance from the transmitter, a Repeater is used to extendtransmission range. In the downlink path the Repeater picks up the signal from a donorantenna of an existing cell, amplifies and re-transmits it into the desired dark spot. In theuplink direction the Repeater receives signals from mobile stations present in its coveragearea and re-transmits them to the corresponding base station.1.2 About the MRx01B PowerThis repeater bi-directionally amplifies signals between multiple mobiles and a single basestation in the frequency band. It is employed where poor topological conditions cause weakfield strengths. It can provide highly selective amplification of band segments or channels inthe frequency band.MRx01B Power modules can be combined with other repeater modules in order to create amulti-band repeater system. Modules operating in PCS1900, GSM1800, GSM900, orAMPS800 bands are available. When different modules are combined a common antenna andcontrol interface are available.The MRx01B Power can be set-up locally or remotely. A PCMCIA slot for modem operationis an available option. The repeater has a large number of functions that can be monitored andchanged by the operators via a terminal emulation program or the MIKOM OMC softwareplatform. An easy to understand and simple to learn communication language is available tohelp the operator query status reports from the repeater or to change settings.1.3 Modular designThe MRx01B repeater’s modular design provides the flexibility in addressing present andfuture system needs. Each repeater is custom configured. The main unit includes equipmentcommon to all systems ( cabinet, control module, power supply, mother board ). To this mainunit hardware modules are added as needed. In addition to different duplexers, a wide rangeof conversion modules can be selected depending on the used network system.

For example, the following are some of the application options available withthe MRx01B.• Channel selective or band selective• CDMA or TDMA• iDEN and analog networks• GSM900 or GSM1800• PCS1900
User’s manual for Repeater MRx01B PowerM0079A1A.doc Id.-No. 151775 Page 13 10-March-002 Functional descriptionThe Repeater MRx01B Power can be equipped from one to four bands or channels dependingon the used technology.The following block diagram shall illustrate the configuration of the system.*: one physical module contains UL and DL**: with more than two modules, the amplifiers are included; both are in one housingfigure 2-1 Block diagram of MRx01B Power2.1 GeneralThe Repeater consists of two amplifier chains, which are connected antiparallel. Thereceive path of one direction is connected to the transmit path of the other direction by afrequency separation unit, in the following denominated as a duplexer, which combinesboth signals to an antenna (see chapter 2.5).After the duplexer the signals get to a pre-amplifier and afterwards to a conversionmodule (see chapter 2.2). Then the signals are combined by the active combiner (seechapter 2.6) and afterwards amplified by the feedforward amplifier (see chapter 2.8),which provides the required output power.
User’s manual for Repeater MRx01B PowerM0079A1A.doc Id.-No. 151775 Page 14 10-March-00In the feedforward amplifier a power detection measures the output power and controlsthe gain. This is called Automatic Level Control (ALC) and keeps intermodulationsbelow an adjustable value. Finally, the signals are fed to the antenna.2.2 Conversion modulesThe task of the conversion modules is to amplify thereceive signals and to convert them into an intermediatefrequency. The signals, then, proceed a filter stagecomprising of highly selective filters, and run through adigital controllable attenuator. The attenuation can beset in steps of 2 dB, locally or remotely. By using thesame synthesizer frequency, that was used to convert thesignals down to intermediate frequency, theintermediate frequency is mixed up to the originalfrequency.The synthesizer is controlled via an I²C-Bus. In case of abreakdown in mains, gain or frequency data are non-volatile stored in an EEPROM on board.The yellow label on the top shows the current ALC andCFO values related to the module.See figure 2-2 Top view of a conversion module for anexemplary channel or band module.figure 2-2 Top view of a conversion module2.3 Mother boardThe function of the mother board is the communication between the conversion modules andthe control module via the I²C-Bus.In the three and four channel configuration there is a mother board implemented on the left-hand side and on the right-hand side of the Repeater.In the one and two channel configuration of the Repeater there is only one mother boardmounted on the right-hand side (see figure 9-2 and figure 9-3).Mother boards are located underneath the conversion modules.

The wholecommunication between the operator and the Repeater can be done via the control module. Byusing either the RS232 interface in connection with a modem card and a mobile the Repeatercan be controlled remotely or locally by using a VT100 terminal, i.e. a PC emulating theVT100 terminal.Frequency and gain, power down of RF stages and ALC can be controlled and statusmessages can be received remotely. In case a modem or a mobile is connected, automaticalarm messages can be received by the operator.The data transfer between the control module SM 2009 and the mother board is realized bythe I²C-Bus system.The I²C-Bus concept was developed by Philips for the serial connection of integrated circuitswithin one device. Two wires, SDA - serial data and SCL - serial clock, carry informationbetween the devices connected to the bus. Each device is recognized by a unique address andcan operate either as transmitter or receiver. The MRx01B Power I²C-Bus concept is workingwith a bit rate of 1.5 kbit/s.All MRx01B Power configuration parameters are stored in an EEPROM on the controlmodule if a power supply failure occurs.

The active combiner will be followed by thefeedforward amplifier.figure 2-7 Top view of the active combiner module2.7 Measuring aidsWith built-in RF probes test signals can be applied or detected. The probes provide a couplingfactor of 30 dB respectivly 20 dB. Each duplexer (uplink and downlink) is equipped with one30 dB coupler, the UL Input duplexer additionally with a 20 dB coupler for a modem ormobile (see chapter 4 Optional equipment). This facilitates measurements under alloperational conditions, while an antenna or a dummy load may be connected.The position of the couplers on the duplexers is shown in figure 2-6 Top view of theduplexers.

By using a rotaryswitch the attenuation can be adjusted locally in the range from 0 dB to 30 dB maximum insteps of 2 dB. The attenuation can be set for the UL and DL path separately.The rotary switches are mounted on the mother board. These switches are accessible throughthe long hole between the two conversion modules (see figure 3-1 Position of rotaryswitches). They can be adjusted easily by means of a small screwdriver.figure 3-1 Position of rotary switchesFor remote control an RS232 interface can be used to set the gain.The functions of the control module may be used locally by means of a VT100 terminal or apersonal computer emulating the VT100 terminal.

User’s manual for Repeater MRx01B PowerM0079A1A.doc Id.-No. 151775 Page 25 10-March-003.3 ALCIn order to protect the amplifiers from overload and to prevent the system to generate spuriousemission, the amplifiers have an Automatic Level Control, designed to limit the output powerto a defined level. A part of the output power is rectified, amplified and used to control anattenuator network.FNote: The ALC protects the feedforward amplifier. To keep spurious emissionsbelow certain limits, the input power into the Repeater and the attenuationsettings of the repeater have to be considered properly.3.4 CFOEach conversion module has got a different offset of the set center frequency. This offset iscompensated by software settings (see software manuals).These settings are already factoryset and should only be changed when neccessary. The CFO (center frequency offset) is notedon the label on top of the conversion module.3.5 BITE and alarmsThe Built-In TEst concept comprises the monitoring of the power supplies, the operationalcurrents in the conversion modules, the mother board and the remote control interface.Furthermore, the synthesizer lock and the temperature of the Repeater are monitored.There are three multicoloured LEDs mounted on the control module. The LED L3 indicatesthe presence of electrical power of +12VDC in the Repeater. Every alarm is indicated by thefailure LEDs, L1 and L2.For the position of the LEDs on the control module see figure 2-4 Configuration of the controlmodule ( Rev.07 and higher ).All alarms can be checked by typing the ‘STATUS HIST’ command. Minor alarms with noinfluence on the system can be cancelled by typing the ‘ALARMACKN’ command, e.g. ALCactive, VSWR or door open. The following print screen illustrates a possible ‘STATUSHIST’ reportIn case a hardware failure is detected the concerning hardware module has to be replaced. Analarm can be acknowledged manually by software command. If all alarms have beenacknowledged the summary error LEDs are set back to green indication.In case of mains power failure all data of the STATUS HIST list are lost.The alarm can also be sent to the OMC.

User’s manual for Repeater MRx01B PowerM0079A1A.doc Id.-No. 151775 Page 27 10-March-003.5.1 Handling of alarmsAs soon as the software recognises a valid alarm, a message is transmitted to the OMC.If the repeater is operating in modem mode the alarm message ‘MIKOM> REPEATERREQUIRES OPERATOR ATTENTION’ will be sent via modem to the terminal or the OMC.The first of two stored telephone numbers will be dialled. In case a connection cannot beestablished the second telephone number will be dialled. If this should be unsuccessful aswell, the call will be repeated after a pre-set delay. Default setting is 10 minutes. Therepetition cycle can be set by software.The alarm check routine is searching every 10 seconds for alarms ( polling principal ). Todecide whether an alarm is a valid alarm it must remain for 5 polling cycles, only then it willbe recognized and entered in the alarm history. As soon as the alarm is valid the contacts ofthe alarm relay at the mother board are set. Additionally two summary error LEDs are set tored light to indicate an alarm. These LEDs are mounted on the control module (see figure2-4).The entry in the alarm history describes the alarm type, the time and the date when itoccurred. It is not possible to locate the defect module, only the reason.Entered alarms in the alarm list can be acknowledged by simply ringing back and typing asoftware command. It is also possible to acknowledge alarms in local mode. Acknowledgedalarms will be indicated with ‘-ACK’. As soon as the alarms have been acknowledged thealarm relay will be reset and the summary LEDs switch back to green light again. To switchoff external alarm indication devices can only be done by acknowledging the alarms.If the same alarm cause occurs again, it will be entered in the alarm list ( not acknowledged )after 5 polling cycles. An already acknowledged alarm must have an interruption of at least 5polling cycles to be detected by the software as a new alarm. Only then the alarm will beentered again in the alarm history ( not acknowledged ).All data of the alarm history are lost, if the repeater will be booted by software or if therepeater was disconnected from mains. There exists no command to delete the alarm history,to boot the repeater is the only way to clear the alarm history.The alarm list has a capacity of about 50 alarm entries. If more alarms occur the oldestmessage will be deleted first ( FIFO principal ).In the software exists no alarm clear message, i.e., the repeater sends no message to theterminal or the OMC if an alarm has disappeared by itself.

Typing the GETcommand will be responded by a listing of all settings of the Repeater. STATUS will beresponded by a listing of all individual status information.The complete listing of the dialogue language with the processor of the control moduleincluding the instructions to and the messages from the system is available as a separatemanual.3.5.3 Severity levelsThis parameter defines five severity levels for an alarm and can be set in the alarm mask(detailed description in the software manual). The severity levels indicate how the capabilityof the managed object has been affected.The levels are described below and are ordered from most severe to least severe:- Critical: The critical severity level indicates that a service affecting condition hasoccurred and an immediate corrective action is required to restore thecapability of the managed object.- Major: The major severity level indicates that a service affecting condition hasdeveloped and an urgent corrective action is required. Such a severity can bereported, for example, when there is a severe degradation in the capability ofthe managed object and its full capability must be restored.- Minor: The minor severity level indicates the existence of a non-service affecting faultcondition and that corrective actions should be taken in order to prevent a moreserious failure. Such a severity can be reported, for example, when the detectedalarm condition is not currently degrading the capability of the managed object.- Warning: The warning severity level indicates the detection of a potential or impendingservice affecting failure before any significant effect has been caused. Action should be taken to further diagnose and correction of the problem shall preventa more serious service affecting failure.- Disable: The disable severity level indicates that the detected failure has no influence onthe system and shall not be sent to the terminal.

The termination can be performed by the antenna connection as well as a dummy load or the 50-Ohm-terminated connectionof a measuring instrument.Before bringing the Repeater system into service it is necessary to measure the antennaisolation. The Repeater system has its maximum available gain when the attenuation is set tozero. On site the maximum allowed gain is 15 dB less than the value of the antenna isolation.In order to check the function of the Repeater system on site it is advisable to operate theRepeater system with 50 Ohm termination. This makes it possible to set the necessary gainand to test the set value without the necessity of transmitting on air.In order to perform settings the Repeater has to be opened. Please, ensure not to damage theseals, which are on the modules situated on the conversion modules inside of the Repeater,because this would lead to risk the success of warranty claims.After taking the Repeater into service following signals occur during the boot process.InternalLED L1 InternalLED L2 InternalLED L3 Causegreen red green red green- - - - ll Power on state,Software boot startsll Flashesred shorttimell Flashes redshort time ll Software boot startsll ll ll Software is runningtable 6-1 LED indication6.2 Setting of operational parametersAttenuation of the Repeater can be set manually by means of rotary switches, frequency canbe set locally or remotely.There are three different possibilities to set the operational parameters:-manual settings by means of rotary switches-local control via RS232 interface and PC-remote control via modem
