1 Introduction
1.1 Intended purpose
Cellular telephone systems transmit signals in two directions between base stations and
mobile 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 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 MOR701B POWER
MIKOM’s MOR701B Power Remote is available as a band selective optical repeater for
GSM, CDMA and TDMA technology and as a channel selective optical repeater for CDMA
and TDMA technology.
A GSM channel selective version is available (MOR 740).
The MOR701B Power Remote repeater bi-directionally amplifies signals between multiple
mobiles and a single base station in the PCS1900 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 PCS1900 band.
The MOR701B Power Remote can be combined with other repeaters in order to create a
multi-band optical repeater system. Modules operating in GSM1800, GSM900, AMPS800, or
iDEN bands are available. When different modules are combined a common antenna and
control interface is available.
The MR701 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.

User’s manual for Remote Unit MOR701B 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.

2.3 Mother board
The function of the mother board is the communication between the RF modules and the
control module via the I²C-Bus.
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.

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 MOR701B Power configuration parameters are stored in an EEPROM on the control
module if a power supply failure occurs.

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.
Two frequency - dependent versions of the MOR701B Power are available:

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.

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.

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.

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.
FNote:
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.

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. These alarms may occur in

3.4.2 Status report
Two instructions enable the operator to gain knowledge of the system status. Typing the GET
command will be responded by a listing of all settings of the Repeater. STATUS will be
responded by a listing of all individual status information.
An example is listed below for a GET1* (REP1009V1.xx) and STATUS report. The listing
contains random data to demonstrate in which way these messages appear.
*: Due to the fact that the report is very long, the GET report can be split in two parts. You have to type GET1 to
see the first and GET2 to see the second part.

3.4.3 Severity levels
This 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 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.

- 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.

VSWR signal is continually measured by a special VSWR module. 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

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.

6.1 Mechanical installation
Note:
Due to power dissipation the Repeater may heat up the air volume inside
the cabinet and reach a very high temperature. 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.

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.
F 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.

6.2 Electrical installation
FNote:
ESD precautions have to be observed! 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.

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.
figure 6-5 Screw terminal
F Note:
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.
F Note:
M0069A0A.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.

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.
F 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.
F Note:
M0069A0A.doc

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.

7 Setting to work
7.1 Preparation
F 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.
After taking the Repeater into service following signals occur during the boot process.

7.2 Setting of operational parameters
Attenuation of the Repeater can be set manually, locally or remotely. 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.
F 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.

The gain can be set 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 7-3 Position of the rotary switches).
They can be adjusted easily by means of a small screwdriver.
