User’s manual for Remote Unit MOR801B PowerM0070A0A.doc Id.-No 151155 Page 13 18-June-991 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 MOR801B POWERMIKOM’s MOR801B Power Remote is available as a band or channel selective opticalrepeater for Analog, CDMA, and TDMA technology.The MOR801B Power Remote repeater bi-directionally amplifies signals between multiplemobiles and a single base station in the AMPS800 frequency band using optical fibres forinterconnection to a Master Unit. It is employed mainly in tunnels, canyons, and other areas,where physical structures cause weak field strengths. It can provide highly selectiveamplification of band segments or channels in the AMPS800 band.The MOR801B Power Remote can be combined with other repeaters in order to create amulti-band optical repeater system. Modules operating in PCS1900, GSM1800, GSM900, oriDEN bands are available. When different modules are combined a common antenna andcontrol interface is available.The MR801 Power Remote can be set-up locally at the Master Unit through the optical fibreor remotely at the OMC. A PCMCIA slot for modem operation is an available option at theMaster Unit. The repeater has a large number of functions that can be monitored and changedby the operators via a terminal emulation program or the MIKOM OMC software platform.An easy to understand and simple to learn communication language is available to help theoperator query status reports from the repeater or to change settings.

User’s manual for Remote Unit MOR801B PowerM0070A0A.doc Id.-No 151155 Page 15 18-June-992.1 GeneralThe Repeater consists of two amplifier chains. The signals to and from the mobiles arecombined to an antenna by a frequency separation unit, denominated in the following asDuplexer. The optical signals to and from the Master Unit are converted by the OpticalTransceiver.In the Downlink direction the optical signals from the Master Unit are converted into RF-signals by the Transceiver (see chapter 2.7). They pass the 4-way-Splitter (see chapter2.9),which provides the RF-signal for the RF modules. After the RF module (see chapter 2.2) theyare combined by the Active Combiner (see chapter 2.6) and afterwards amplified by the FeedForward Amplifier (see chapter 2.12), which provides the required output power. Finally thesignals are fed to the antenna by the Duplexer (see chapter 2.5).In the Uplink direction the signals from the mobiles are seperated by the Duplexer, get to aPre-Amplifier and afterwards to an RF module. The signals are combined by the ActiveCombiner then, get converted into optical signals by the Transceiver (see chapter 2.7) and arefinally transmitted to the Master Unit.In the final amplifier of the Downlink a power detection measures the output power andcontrols the gain. In the Uplink the gain is controlled by the Active Combiner to protect theOptical Transceiver. This power detection is called Automatic Level Control (ALC) (seechapter 3.3).2.2 RF modulesThe task of the RF modules is to amplify the receive signals and to convert them into anintermediate frequency. The signals, then, proceed a filter stage comprising of highly selectivefilters, and run through a digital controllable attenuator. The attenuation can be set in steps of2 dB, locally or remotely. By using the same synthesizer frequency, that was used to convertthe signals down to intermediate frequency, the intermediate frequency is mixed up to theoriginal frequency.The synthesizer is controlled via an I²C-Bus. In case of a breakdown in mains, gain andfrequency data are non-volatile stored in an EEPROM on board.See figure 2-2 Top view of an RF module for an exemplary channel or band module.

User’s manual for Remote Unit MOR801B PowerM0070A0A.doc Id.-No 151155 Page 18 18-June-992.4 Control module SM 2009The control module SM 2009 is a DOS compatible micro computer. The wholecommunication between the operator and the Repeater can be done via the control module. Byusing the RS232 interface the Repeater can be controlled locally by using a VT100 terminal,or a PC emulating the VT100 terminal.Frequency and gain, power down of RF stages and ALC can be controlled and statusmessages can be received remotely via the Master Unit.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 data betweenthe devices connected to the bus. Each device is recognized by a unique address and canoperate either as transmitter or receiver.All MOR801B Power configuration parameters are stored in an EEPROM on the controlmodule if a power supply failure occurs.figure 2-4 Top view of the control module

User’s manual for Remote Unit MOR801B PowerM0070A0A.doc Id.-No 151155 Page 25 18-June-993 Functions and features3.1 Band and channel selectivityThe selectivity is achieved by highly selective filters in the IF part of the band / channelmodules.3.2 Gain settingThe gain can be changed by introducing attenuation into the amplifier chain. 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 RF modules (see figure 3-1 Position of rotary switches). Theycan 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.

A part of the output power is rectified, amplified and used to control anattenuator network. In order to avoid oscillation, the control amplifier has an integratingcharacteristic, so that a step function response obtains a delayed rise and decay.Note: The ALC protects the final amplifier and the optical devices. To keepspurious emissions below certain limits, the input power into the Repeaterand the attenuation settings of the Repeater have to be consideredproperly.3.4 BITE and alarmsThe Built-In TEst concept comprises the monitoring of the power supplies, the operationalcurrents in the RF 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.Position of the LEDs on the control module is shown in the following figure.figure 3-2 Position of failure LEDs

User’s manual for Remote Unit MOR801B PowerM0070A0A.doc Id.-No 151155 Page 42 18-June-996.1 Mechanical installation Note: Due to power dissipation the Repeater may heat up the air volume insidethe cabinet and reach a very high temperature. Therefore it is necessary to mount theRepeater in the vertical plane to a wall or a mast without additional enclosure to providesufficient ventilation. Between the housing and the wall a minimum distance must bekept in order to provide air circulation. Note: The weight of the MOR801B Power is approximately 47 kg in standardconfiguration.The Repeater must be mounted in the verticalplane to a wall or a mast, which means theconnectors have to be located at the bottom.Use the mounting brackets, which are part of thedelivery. This will guarantee a minimumdistance between the wall and the Repeaterhousing. The cabinet must be fixed to the wall(brackets) with four screws.Check the correspondence of the wall mountingkit and the wall.
User’s manual for Remote Unit MOR801B PowerM0070A0A.doc Id.-No 151155 Page 43 18-June-99Mounting procedure:Dismount the mounting brackets first. They are screwed tight to the housing with four sockethead cap screws M8.0x16 (see figure below) and two tire bolts.figure 6-2 Wall mounting bracketsUse the wall mounting sheet to mark the position of the drilling holes. Drill 4 holes and screwthe mounting brackets to the wall. Attach the upper two socket head cap screws M8.0x16 tothe Repeater housing. Now it is possible to hang the Repeater into the mounting brackets. Fixthen the lower two socket head cap screws M8.0x16 and the 2 tire bolts. Note: The unit is heavy-weight. Make sure that a suitable mounting surface isused. Only adequate manpower is allowed to handle the system.The installation position of the Repeater follows from the installation drawing, see figure 12-1Installation drawing of the Repeater. Make sure that there is free access to the electricalconnections. The allowed bending radius of the connected cables must not be exceeded.Furthermore the Repeater shall be mounted in a way that there is free access to the individualunits inside the cabinet, while the door of the Repeater is open.Therefore keep a clearance distance of 1 m on each side, above and below the unit.See following figure 6-3 Clearance distance.mounting brackets

Before working inside the cabinetuse the available grounding system to connect ESD protection measures.The electrical installation has to be performed in accordance with thesafety regulations of the local authorities. Due to safety reasons theelectrical installation must be performed by qualified personnel. Thecover of this unit should not be opened while power is applied.Subsequent installation, commissioning and maintenance activities thatrequire the unit to be powered with the cover open shall only be carriedout by suitably qualified personnel6.2.1 GroundingGrounding has to be performed by all means. Therefore a grounding bolt is provided at thecabinet. An earth bonding cable will be mounted in the factory and will be delivered with theunit. Don’t use the grounding screw for connecting external devices.The complete grounding kit is part of the delivery schedule.figure 6-4 Grounding kit
User’s manual for Remote Unit MOR801B PowerM0070A0A.doc Id.-No 151155 Page 46 18-June-996.2.2 Power connectionBefore connecting electrical power to the Repeater grounding has to be performed. TheRepeater is equipped with a firmly connected power cord. Due to safety reasons the powersupply lead of the Repeater has to be protected with two 8 A fuses, type MT. In the event thelength of the power cord should not be sufficient it can be replaced by a longer cable.figure 6-5 Screw terminal Note: If the power supply lead has to be replaced use a cable of the same quality.6.2.3 Connection of the antenna cableThe Repeater has a female antenna connector 7/16 (or N with adapter). For mounting thecorresponding cable connector we recommend to refer to the applicable documentation of therespective connector manufacturer. The bending radius of the antenna cable must remainwithin its specification. This will warrant proper operation of the system; otherwise changesin the electrical behaviour of the cable might occur which could cause malfunction of theRepeater system. Note: It is sufficient to fix the 7/16 (or N) antenna connector hand-screwed.Any use of a tool (like tongs) might cause damage to the connector andthus lead to malfunctioning of the Repeater.
User’s manual for Remote Unit MOR801B PowerM0070A0A.doc Id.-No 151155 Page 47 18-June-996.2.4 Connecting fibre optic cablesThe standard transmission of the optical signals is carried out by means of an optical fibre pairfor each Remote Unit. Note: Extreme care should be taken when connecting and disconnecting thefibre optic cable. Scratches and dust significantly affect system performance and may permanently damage the connector, necessitating re-termination. Always use protective caps on fibre optic connectors and receptacles when not used.The structure of the cable is not critical. However, demands of the site as for example rodentprotection and so on have to be kept in mind.The optical fibre is a single mode fibre. The type is E9/125 with the following minimumrequirements.Attenuation < 0.3 dB/km @ 1300 nmDispersion < 3.5 ps/nm*km @ 1300 nmThe allowed bending radius of the optical fibres must be kept by all means at any time.The pig tails for the connection between Master and Remote Unit must have a sufficientlength. A protection for the feeding into units has to be given.The system attenuation of the optical fibres including the connectors must not exceed 10 dB.Less than 5 dB is desired.The system attenuation and the attenuation of the opical components have to be determined.This can be achieved by measuring the attenuation and the reflection with an appropriatemeasuring instrument. For pig tails a total value of < 0.4 dB ( measured to a reference plug )can be assumed due to the dead zone of the reflectometre. These measurements have to bemade with a sufficient length of optical fibre in front of and behind the device to be measured.The fibre cables should be terminated with the same type of connector (DIN 8° or SC/APC8°) as is used in the unit. The fibre optic cables are connected to the optical Transceiver andreceiver. Note: Angled connectors are not compatible with straight optical connectors;non-compatibility of connectors will result in permanent damage to bothwaiting connectors.
User’s manual for Remote Unit MOR801B PowerM0070A0A.doc Id.-No 151155 Page 48 18-June-99Before connecting the fibre cables, follow the procedures below to ensure properperformance. It is important that these procedures be performed with care:1. Remove fibre optic protective caps. 2. Do not bend the fibre optic cable in a tight radius (<4 cm) as this may cause cable damageand interrupt transmission. 3. Using high-grade alcohol and lint-free cotton cleaning swabs, clean the end of the fibreoptic cable that will be inserted in the optical connectors on the donor interface box. 4. Blow the end dry with clean, dry compressed air. 5. Vigorously blow out the laser receptacle with clean, dry compressed air to remove anyparticulate matter. 6. Connect the fibre optic cables by inserting the cable end into the laser receptacle andaligning the key (on the cable end) with the keyed slot. 7. Do not use any index matching gels or fluids of any kind in these connectors. Gels areintended for laboratory use and attract dirt in the field.
User’s manual for Remote Unit MOR801B PowerM0070A0A.doc Id.-No 151155 Page 49 18-June-997 Setting to work7.1 Preparation Note: It is not allowed to operate the Repeater without termination of the antenna connections! 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 RF modules inside of the Repeater, becausethis 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---- Power on state,Software boot startsFlashesred shorttimeFlashes redshort time Software boot startsSoftware is runningtable 7-1 LED indication

Frequency can be setlocally and 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 Master Unit7.2.1 Manual setting of the attenuation by means of rotary switchesThe manual mode allows the user to set the required attenuation by means of rotary switches.With a small screwdriver, which fits through the long holes of the RF modules, the values canbe adjusted by turning the switch carefully to the desired position. Note: To enable manual settings of parameters the mode switch (DIP-Switch 1)has to be changed from OFF to ON.The DIP-Switch is mounted on the control module, located on the left-hand side of theRepeater.figure 7-2 Position of the DIP-Switch 1DIP-Switch 1
User’s manual for Remote Unit MOR801B PowerM0070A0A.doc Id.-No 151155 Page 51 18-June-99The gain can be set by introducing attenuation into the amplifier chain. 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 RF modules ( see figure 7-3 Position of the rotary switches).They can be adjusted easily by means of a small screwdriver.figure 7-3 Position of the rotary switchesA label on the RF module, located next to the rotary switch, illustrates the usage of the rotaryswitch (see figure 7-4 Rotary switches and label).figure 7-4 Rotary switches and label Note: Gain can be changed independently for the uplink and downlink path.DIP-Switch configuration:long hole
