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 extend transmission range. In the downlink path the Repeater picks up the signal from a donor antenna of an existing cell, amplifies and re-transmits it into the desired dark spot. In the uplink direction the Repeater receives signals from mobile stations present in its coverage area and re-transmits them to the corresponding base station. 1.2 About the MOR801B POWER MIKOM’s MOR801B Power Remote is available as a band or channel selective optical repeater for Analog, CDMA, and TDMA technology. The MOR801B Power Remote repeater bi-directionally amplifies signals between multiple mobiles and a single base station in the AMPS800 frequency band using optical fibres for interconnection 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 selective amplification of band segments or channels in the AMPS800 band. The MOR801B Power Remote can be combined with other repeaters in order to create a multi-band optical repeater system. Modules operating in PCS1900, GSM1800, GSM900, or iDEN bands are available. When different modules are combined a common antenna and control interface is available. The MR801 Power Remote can be set-up locally at the Master Unit through the optical fibre or remotely at the OMC. A PCMCIA slot for modem operation is an available option at the Master Unit. The repeater has a large number of functions that can be monitored and changed by 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 the operator query status reports from the repeater or to change settings. M0070A0A.doc Id.-No 151155 Page 13 18-June-99 User’s manual for Remote Unit MOR801B Power 2 Functional description The Repeater MOR801B Power can be equipped from one to four bands or channels. The following block diagram shall illustrate the configuration of the system. *: one physical module contains UL and DL **: with more than two channels, the amplifier is included *** For correct cabling see Assembly Guide figure 2-1 Block diagram of MOR801B Power M0070A0A.doc Id.-No 151155 Page 14 18-June-99 User’s manual for Remote Unit MOR801B Power 2.1 General The Repeater consists of two amplifier chains. The signals to and from the mobiles are combined to an antenna by a frequency separation unit, denominated in the following as Duplexer. The optical signals to and from the Master Unit are converted by the Optical Transceiver. In the Downlink direction the optical signals from the Master Unit are converted into RFsignals 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) they are combined by the Active Combiner (see chapter 2.6) and afterwards amplified by the Feed Forward Amplifier (see chapter 2.12), which provides the required output power. Finally the signals 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 a Pre-Amplifier and afterwards to an RF module. The signals are combined by the Active Combiner then, get converted into optical signals by the Transceiver (see chapter 2.7) and are finally transmitted to the Master Unit. In the final amplifier of the Downlink a power detection measures the output power and controls the gain. In the Uplink the gain is controlled by the Active Combiner to protect the Optical Transceiver. This power detection is called Automatic Level Control (ALC) (see chapter 3.3). 2.2 RF modules The task of the RF modules is to amplify the receive signals and to convert them into an intermediate frequency. The signals, then, proceed a filter stage comprising of highly selective filters, and run through a digital controllable attenuator. The attenuation can be set in steps of 2 dB, locally or remotely. By using the same synthesizer frequency, that was used to convert the signals down to intermediate frequency, the intermediate frequency is mixed up to the original frequency. The synthesizer is controlled via an I²C-Bus. In case of a breakdown in mains, gain and frequency 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.

In the three and four channel configuration of the Repeater there is a mother board on the leftand on the right-hand side, whereas in the one and two channel configuration there is only one mother board implemented on the right-hand side of the Repeater. Mother boards are located underneath the RF modules. figure 2-3 Top view of a mother board M0070A0A.doc Id.-No 151155 Page 17 18-June-99 User’s manual for Remote Unit MOR801B Power 2.4 Control module SM 2009 The control module SM 2009 is a DOS compatible micro computer. The whole communication between the operator and the Repeater can be done via the control module. By using 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 status messages can be received remotely via the Master Unit. The data transfer between the control module SM 2009 and the mother board is realized by the I²C-Bus system. The I²C-Bus concept was developed by Philips for the serial connection of integrated circuits within one device. Two wires, SDA - serial data and SCL - serial clock, carry data between the devices connected to the bus. Each device is recognized by a unique address and can operate either as transmitter or receiver. All MOR801B Power configuration parameters are stored in an EEPROM on the control module if a power supply failure occurs. figure 2-4 Top view of the control module M0070A0A.doc Id.-No 151155 Page 18 18-June-99 User’s manual for Remote Unit MOR801B Power 2.5 Duplexer The task of the duplexer is to isolate uplink from downlink, i.e. isolate transmit path from receive path. The pass bandwidth of the duplexer is the entire width of the uplink band and the downlink band. UL frequency DL frequency 824 - 849 MHz 869 - 894 MHz RF probe 30 dB figure 2-5 Top view of the duplexer M0070A0A.doc Id.-No 151155 Page 19 18-June-99 User’s manual for Remote Unit MOR801B Power 2.6 Active Combiner After passing through the RF modules, the signals will be combined by the Active Combiner module in the UL and in the DL path. The Active Combiner will be followed by the feed forward amplifier in the DL and by the Transceiver in the UL. figure 2-6 Top view of an Active Combiner module 2.7 Transceiver MFY1309 The Transceiver MFY1309 is the interface between the optic and the electrical distribution unit. The function of the Transceiver is to convert the optical signal into an electrical signal and vice versa. figure 2-7 Transceiver MFY1309 M0070A0A.doc Id.-No 151155 Page 20 18-June-99 User’s manual for Remote Unit MOR801B Power Transceiver MFY1309 Optical connectors figure 2-8 Installation position of the Transceiver The configuration of the connecting pins is shown in the following figure. connecting pins Pin 1 Pin 2 Pin 3 Pin 4 Pin 5 Pin 6 Pin 7 Pin 8 GND Rx Alarm normally closed Tx Alarm common Vcc Rx Alarm common Rx Alarm normally open Tx Alarm normally closed Tx Alarm normally open figure 2-9 Configuration of the connecting pins 2.8 FSK modulator To enable remote control between the Master Unit and the Remote Units a serial interface will be implemented, in the following designated as FSK modulator. Signals from the Remote Unit will be modulated to a 10.7 MHz carrier and are fed to the optical Transceiver to be transmitted to the Master Unit via optical vibre and vice versa. M0070A0A.doc Id.-No 151155 Page 21 18-June-99 User’s manual for Remote Unit MOR801B Power 2.9 4-way-Splitter The 4-way-Splitter provides the RF-signal to the RF modules. It splits up the signal from the Receiver and provides four equal RF outputs with an attenuation of 10 dB for the RF modules. It is mounted underneath the Optical Transceiver and can be seen only, if the Transceiver is dismounted. figure 2-10 Top view of the 4-way-Splitter (Transceiver dismounted) 2.10 Measuring aids With the built-in RF probe test signals can be applied or detected. The duplexer is equipped with a probe which provides a coupling factor of 30 dB. This facilitates measurements under all operational conditions, while an antenna or a dummy load may be connected. The position of the coupler on the duplexer is shown in figure 2-5 Top view of the duplexer. 2.11 Power supply For the MOR801B Power three power supplies are necessary. Power supplies are available with different mains power. See list below for available power supplies.

The power supply is factory-set. 2.12 Feed forward amplifier The feed forward amplifier is the final stage which enables high output power as well as a high ICP3. One amplifier is installed for the DL Out path. figure 2-13 Top view of the feed forward amplifier M0070A0A.doc Id.-No 151155 Page 24 18-June-99 User’s manual for Remote Unit MOR801B Power 3 Functions and features 3.1 Band and channel selectivity The selectivity is achieved by highly selective filters in the IF part of the band / channel modules. 3.2 Gain setting The gain can be changed by introducing attenuation into the amplifier chain. By using a rotary switch the attenuation can be adjusted locally in the range from 0 dB to 30 dB maximum in steps 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 through the long hole between the two RF modules (see figure 3-1 Position of rotary switches). They can be adjusted easily by means of a small screwdriver. long hole figure 3-1 Position of rotary switches For 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 a personal computer emulating the VT100 terminal. See also chapter 7.2, which deals with settings of operational parameters. M0070A0A.doc Id.-No 151155 Page 25 18-June-99 User’s manual for Remote Unit MOR801B Power 3.3 ALC In order to protect the final amplifier and the optical devices from overload and to prevent the system to generate spurious emission, the amplifier for the DL Out and the Active Combiner for the UL Out have an Automatic Level Control, designed to limit the output power to a defined level. A part of the output power is rectified, amplified and used to control an attenuator network. In order to avoid oscillation, the control amplifier has an integrating characteristic, so that a step function response obtains a delayed rise and decay. Note: The ALC protects the final amplifier and the optical devices. To keep spurious emissions below certain limits, the input power into the Repeater and the attenuation settings of the Repeater have to be considered properly. 3.4 BITE and alarms The Built-In TEst concept comprises the monitoring of the power supplies, the operational currents 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 indicates the presence of electrical power of +12VDC in the Repeater. Every alarm is indicated by the failure 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 M0070A0A.doc Id.-No 151155 Page 26 18-June-99 User’s manual for Remote Unit MOR801B Power All alarms can be checked by typing the ‘STATUS HIST’ command. It is possible to cancel minor alarms with no influence on the system by typing the ‘ALARMACKN’ command, e.g. ALC active, VSWR or door open. The following print screen illustrates a possible ‘STATUS HIST’ report figure 3-3 Status hist report In case a hardware failure is detected the concerning hardware module has to be replaced. An alarm can be acknowledged manually by software command. If all alarms have been acknowledged 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. The following list comprises all available alarms in the Repeater.

The severity levels indicate how the capability of 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 has occurred and an immediate corrective action is required to restore the capability of the managed object. - Major: The major severity level indicates that a service affecting condition has developed and an urgent corrective action is required. Such a severity can be reported, for example, when there is a severe degradation in the capability of the managed object and its full capability must be restored. - Minor: The minor severity level indicates the existence of a non-service affecting fault condition and that corrective actions should be taken in order to prevent a more serious failure. Such a severity can be reported, for example, when the detected alarm condition is not currently degrading the capability of the managed object. M0070A0A.doc Id.-No 151155 Page 30 18-June-99 User’s manual for Remote Unit MOR801B Power - Warning: The warning severity level indicates the detection of a potential or impending service affecting failure before any significant effect has been caused. Action should be taken to further diagnose and correction of the problem shall prevent a more serious service affecting failure. - Disable: The disable severity level indicates that the detected failure has no influence on the system and shall not be sent to the terminal.

An alarm can be given for VSWR < 10 dB. 4.2 External alarms With the following option it is possible to monitor 4 external alarms via the Repeater software. Hence the status of the connected device, e.g. UPS, can be monitored. The contacts of the alarms can be accessed at clamps on the main board (right-hand side of the Repeater). figure 4-1 Clamps for external alarms M0070A0A.doc Id.-No 151155 Page 32 18-June-99 User’s manual for Remote Unit MOR801B Power The electrical connection has to be as follows. External alarm 1 (low active) External alarm 2 (low acitve) External alarm 3 (high active) External alarm 4 (high active) Ground Configuration: 5 V / 0.5 mA max. for open collector applications. All external alarms are normally high without connection. Due to the fact that the external alarms 3 and 4 are high active, they have to be connected to ground to prevent an alarm message. The factory-set response after typing the software command STATUS EXTALARM is for instance „EXT. ALARM 1 OK“, if the alarm is not active and „EXT. ALARM 1 FAILURE“, if the alarm is active. The name for each external alarm and the name for the alarm message can be defined by the customer with the corresponding software command. The following example describes the response for the external alarms to control a UPS. Example: External alarms if the UPS is active EXTERNAL ALARM STATUS UPS alarm active Battery low ! UPS door open Battery door open or External alarms if the UPS is not active EXTERNAL ALARM STATUS UPS not active Battery OK UPS door closed Battery door closed For the DC wiring an additional cable bridge has to be installed on the control module (see figure 4-2 Cable configuration and installation position).

Therefore it is necessary to mount the Repeater in the vertical plane to a wall or a mast without additional enclosure to provide sufficient ventilation. Between the housing and the wall a minimum distance must be kept in order to provide air circulation. The Repeater must be mounted in the vertical plane to a wall or a mast, which means the connectors have to be located at the bottom. Use the mounting brackets, which are part of the delivery. This will guarantee a minimum distance between the wall and the Repeater housing. The cabinet must be fixed to the wall (brackets) with four screws. Check the correspondence of the wall mounting kit and the wall. Note: M0070A0A.doc The weight of the MOR801B Power is approximately 47 kg in standard configuration. Id.-No 151155 Page 42 18-June-99 User’s manual for Remote Unit MOR801B Power Mounting procedure: Dismount the mounting brackets first. They are screwed tight to the housing with four socket head cap screws M8.0x16 (see figure below) and two tire bolts. mounting brackets figure 6-2 Wall mounting brackets Use the wall mounting sheet to mark the position of the drilling holes. Drill 4 holes and screw the mounting brackets to the wall. Attach the upper two socket head cap screws M8.0x16 to the Repeater housing. Now it is possible to hang the Repeater into the mounting brackets. Fix then 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 is used. Only adequate manpower is allowed to handle the system. The installation position of the Repeater follows from the installation drawing, see figure 12-1 Installation drawing of the Repeater. Make sure that there is free access to the electrical connections. 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 individual units 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.

Before working inside the cabinet use the available grounding system to connect ESD protection measures. The electrical installation has to be performed in accordance with the safety regulations of the local authorities. Due to safety reasons the electrical installation must be performed by qualified personnel. The cover of this unit should not be opened while power is applied. Subsequent installation, commissioning and maintenance activities that require the unit to be powered with the cover open shall only be carried out by suitably qualified personnel 6.2.1 Grounding Grounding has to be performed by all means. Therefore a grounding bolt is provided at the cabinet. An earth bonding cable will be mounted in the factory and will be delivered with the unit. 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 M0070A0A.doc Id.-No 151155 Page 45 18-June-99 User’s manual for Remote Unit MOR801B Power 6.2.2 Power connection Before connecting electrical power to the Repeater grounding has to be performed. The Repeater is equipped with a firmly connected power cord. Due to safety reasons the power supply lead of the Repeater has to be protected with two 8 A fuses, type MT. In the event the length of the power cord should not be sufficient it can be replaced by a longer cable. Note: figure 6-5 Screw terminal If the power supply lead has to be replaced use a cable of the same quality. 6.2.3 Connection of the antenna cable The Repeater has a female antenna connector 7/16 (or N with adapter). For mounting the corresponding cable connector we recommend to refer to the applicable documentation of the respective connector manufacturer. The bending radius of the antenna cable must remain within its specification. This will warrant proper operation of the system; otherwise changes in the electrical behaviour of the cable might occur which could cause malfunction of the Repeater system. Note: M0070A0A.doc 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 and thus lead to malfunctioning of the Repeater. Id.-No 151155 Page 46 18-June-99 User’s manual for Remote Unit MOR801B Power 6.2.4 Connecting fibre optic cables The standard transmission of the optical signals is carried out by means of an optical fibre pair for each Remote Unit. Note: Extreme care should be taken when connecting and disconnecting the fibre 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 rodent protection 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 minimum requirements. Attenuation Dispersion < 0.3 dB/km @ 1300 nm < 3.5 ps/nm*km @ 1300 nm The 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 sufficient length. 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 appropriate measuring 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 be made 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/APC 8°) as is used in the unit. The fibre optic cables are connected to the optical Transceiver and receiver. Note: M0070A0A.doc Angled connectors are not compatible with straight optical connectors; non-compatibility of connectors will result in permanent damage to both waiting connectors. Id.-No 151155 Page 47 18-June-99 User’s manual for Remote Unit MOR801B Power Before connecting the fibre cables, follow the procedures below to ensure proper performance. 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 damage and interrupt transmission. 3. Using high-grade alcohol and lint-free cotton cleaning swabs, clean the end of the fibre optic 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 any particulate matter. 6. Connect the fibre optic cables by inserting the cable end into the laser receptacle and aligning 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 are intended for laboratory use and attract dirt in the field. M0070A0A.doc Id.-No 151155 Page 48 18-June-99 User’s manual for Remote Unit MOR801B Power 7 Setting to work 7.1 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 connection of a measuring instrument. Before bringing the Repeater system into service it is necessary to measure the antenna isolation. The Repeater system has its maximum available gain when the attenuation is set to zero. 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 the Repeater system with 50 Ohm termination. This makes it possible to set the necessary gain and 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 the seals which are on the modules situated on the RF modules inside of the Repeater, because this would lead to risk the success of warranty claims.

Frequency can be set locally 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 Unit 7.2.1 Manual setting of the attenuation by means of rotary switches The 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 can be 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 the Repeater.

By using a rotary switch the attenuation can be adjusted locally in the range from 0 dB to 30 dB maximum in steps 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 through the 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. long hole figure 7-3 Position of the rotary switches A label on the RF module, located next to the rotary switch, illustrates the usage of the rotary switch (see figure 7-4 Rotary switches and label).

M0070A0A.doc Id.-No 151155 Page 56 18-June-99 User’s manual for Remote Unit MOR801B Power 9 Maintenance 9.1 General Note: The Repeater does not require preventative maintenance measures. It is only recommended to replace the RAM/RTC battery after three years usage as a prophylactic measure. The nominal lifetime of these batteries is five years under normal environmental conditions. In the event of a malfunction it is advantageous to check the status of the antenna systems as well as the continuity of the entire cabling including connectors, before replacing the modules. Maintenance on the Repeater shall be performed only by replacing modules. Soldering on printed circuit boards shall be avoided. In order to sustain warranty take care not to damage unintentionally the seals on the modules. The spare part list, consequently, contains only units, which can be replaced without tuning or complex soldering work. Note: figure 9-1 Top view of the Repeater Defect parts should only be replaced by original parts from MIKOM. All interventions inside the housing are at one’s own risk. During maintenance ensure that the Repeater has been disconnected from mains. Open the lock at the connector panel and remove the cover plate. To open the housing use a Torx key and unscrew the four Torx screws. 9.2 Replacement of the fuses (mains) The mains cable is protected with two fuses F1 and F2 8A type MT. They are accessible inside of the Repeater at the fuse terminal on the right-hand side. Open the screw plug for the fuse and take out the fuse. Note: Use only fuses of the same type and the same rating when replacing! See figure 9-2 Fuse terminal for position of the 8A fuses.
