1 Introduction
1.1 Radio Description
The MDR2400-SR, MDR5800-SR, Orion2410-SRi and Orion5810-SRi are ISM band
digital radio systems that provide short to medium range, point-to-point digital
communication with high data security at rates of T1, 2T1 or 4T1. Alternatively, the
radio can be software configured to convey E1, 2E1 or 4E1. The radio can also be
configured to bridge or route IP via a 10BaseT port. The data rates scale depending
on the number of enabled T1/E1 tributaries and whether the data is being bridged or
routed. The products make use of spread spectrum technology and may be operated
license-free in the 2.4GHz and 5.8GHz ISM bands.
The Orion 5825-SR is a similar radio also operating in the 5.8GHz ISM band.
Modulation can be switched between 16 and 32 QAM with digital output scalable up to
8T1/E1.
The radios are ideal for applications such as:
• Cellular/PCS base station interconnects.
• Telecommunications companies, cellular operators and private carriers.
• State Local and Federal Government communication systems.
• Video surveillance data distribution.
• Power utilities.
• Petroleum/gas collection companies.
• Rural communications.
• Emergency/disaster telephone service restoration.
• Internet distribution.
The radio consists of two main parts:
• An RF Unit operating in the 2.4 GHz or 5.8 GHz ISM frequency bands.
This could be an MDR2400ET, MDR5800, Orion2410i, Orion5810i or an Orion
5850 unit. The units with an “i” suffix is 1U Indoor RFUs.
• An Digital Indoor Unit, available with a Telecommunications (1, 2 or 4T1/E1 and up
to 8T1/E1 on the Orion 5825) interface and a Data interface (10BaseT Ethernet).
This could be an MDRTE, an MDRETU (75 Ohm BNC), Orion10 or an Orion25
unit. All DIUs operate with the MDR2400ET, MDR5800 and Orion10i RFUs.
Only the Orion type DIUs operate with the Orion type RFUs.
Interconnection between the RF Unit and Digital Indoor Unit is achieved using a low-
cost UV-protected STP (Screened Twisted Pair: 4 pairs) data cable and a UV-
protected 2-core power cable. The split Digital Indoor Unit and RF Unit configuration
is used for the lowest loss between the antenna and the transceiver, thereby ensuring
optimal long-range performance.
The RF Units use a Type-N RF (female) output connector for connection to a coaxial
cable jumper when co-located with a 2.4 GHz or a 5.8 GHz antenna for applications
where long range is required.
MDR2400/5800-SR, Orion2410/5810-SRi and Orion 5825-SR
862-01881 Issue 12c Page 11
The RF Unit can also be located remote from the antenna (tower base or indoor
mounted). The RF connector is then connected to the antenna via a coaxial
transmission line. An optional indoor rack mounting adapter is available for mounting
the RFU, indoors.
The system is available for use in FCC regulated countries.

2 Technical Description
2.1 System Overview
A digital radio link (DRL) consists of a pair of MDR / Orion radio stations.
The radio stations consists of two main parts:
• An RF Unit operating in the 2.4GHz or 5.8 GHz ISM frequency bands. The RF
Unit provides the radio transceiver functionality by accepting radio link data from
the Digital Indoor Unit and converting it to the 2.4GHz or 5.8 GHz ISM frequency
band using spread spectrum or QAM modulation. The received signal is de-
modulated and transmitted to the Digital Indoor Unit in a digital format.
• An Digital Indoor Unit, available with 1, 2, 4 or 8 T1 and 1, 2, 4 or 8 E1 data
interfaces (choice of T1 or E1 is software selectable). The Digital Indoor Unit
combines nT1 or nE1 data with Wayside Service Channel serial data and link IP
data to be transmitted across the radio link. The Digital Indoor Unit also provides
power to the RF Unit.
Interconnection between RF Unit and Digital Indoor Unit is achieved using low cost
data and power cables.
2.2 RF Unit
The MDR2400, MDR5800, Orion2410i and Orion5810i RF Units make use of Spread
Spectrum modulation technology for license-free operation in the 2.4GHz and 5.8 GHz
ISM bands. The Orion5850 RF Unit uses three software selectable bandwidths for
license-free operation in the 5.8 GHz ISM band.
The Orion2410i and Orion5810i RFUs are MDR2400 and MDR5800 RFUs
respectively, that have been repackaged into 1U units that should be used in indoor
unit applications only. Please refer to Appendix K for more detail.
For operation, the ISM bands are divided into upper and lower frequency sub-bands.
A ‘High Band’ RF Unit transmits in the higher frequency sub-band and receives in the
lower frequency sub-band, while a ‘Low Band’ RF Unit transmits in the lower sub-band
and receives in the higher sub-band. An MDR / Orion radio link will use a ‘Low Band’
RF Unit on one end of the link to communicate with a ‘High Band’ RF Unit on the other
end.
The RF Units use a Type-N RF output connector for connection to suitable 2.4GHz
and 5.8GHz antennas for applications where long range is required.
The system is available for use in FCC regulated countries.

2.2.1 Frequency plans
The MDR5800, Orion5810i and the Orion 5850 RF Units operate in the 5.725 GHz to
5.850 GHz ISM frequency band with predefined frequency channel plans (termed A, B,
C and D). Channel plan D is user selectable / adjustable.
The MDR2400 and Orion2410i RF Units operate in the 2.400 GHz to 2.4835 GHz ISM
frequency band with predefined frequency channel plans (termed A, B and D).
Channel plan D is user selectable / adjustable.
2.2.1.1 MDR5800 and Orion5810i Frequency Channel Plan A, B and C
The channel spacing is based on the bandwidth occupied by the spread spectrum
signal (approximately 17 MHz) and is used to optimise link performance. In the case
of plan A, plan B and C, note that both RF Units of a link must be set up to the same
frequency channel plan (i.e. A, B or C).

The channel spacing is based on the transmit bandwidth, either 3 MHz, 6 MHz, or 10
MHz, software selectable. Different bandwidths can be selected dependent on the
optimum link performance; required system sensitivity versus data transfer rate.
Only channel frequencies that are FCC compliant can be selected through the
configuration software. The channel frequency ranges are programmed into the radio
firmware and cannot be adjusted by the user.
The radios were tested and approved for FCC compliance with the frequency ranges
below, see Figure 4.

NOTE 1 Both RF Units in a link must be set to the same frequency channel plan (i.e.
A, B, C or D) and modulator type. Also note that the frequencies differ for different
transmit bandwidths, i.e. the frequency of channel A changes according to the transmit
bandwidth.
NOTE 2 Figure 4 reflects all the frequency bands that could be obtained with the
ORION5850 RFU. Pre-programmed frequency ranges in the radio firmware prevent
the user from selecting transmission options that will not meet FCC requirements.

Figure 4. Orion 5850 Frequency channel plans A, B and C. Refer to NOTE 2 above with
regards to FCC standards compliance of the different band plans.
2.2.1.5 Frequency Channel Plan D (FCC Compliant)
Frequency plan D allows independent control of transmit and receive frequencies.
This allows a flexible frequency plan and can be used to overcome interference in the
2.4GHz and 5.8 GHz ISM bands.
The frequencies that can be used in the lower or upper sub-bands can be selected in
1 MHz increments. Performance degradation can be expected when operating using
channel plan D mode with the chosen frequencies close to the sub-band edges i.e. a
choice of one of the high frequencies in the lower sub-band and one of the lower
frequencies in the upper sub-band.
The allocation of Channel plan D frequencies is shown in Table 4, Table 5 and Table
6.The Orion 5825 has up to three different sets of minimum and maximum
frequencies, which are determined by the data rate setting of the RFU.
Only channel frequencies that are FCC compliant can be selected through the
configuration software. The channel frequency ranges are programmed into the radio
firmware and cannot be adjusted by the user.
The radios ware tested and approved for FCC compliance with the frequency ranges
below, see Figure 4.

3 Planning
This chapter is aimed at management and planning staff to enable them to assess the
requirements for installing an MDR / Orion digital radio link.
3.1 System Type Selection
The system uses an RF Unit with a type-N RF output for connection to a range of
antennas.
The MDR / Orion is aimed at FCC regulated markets.
Antenna polarization can used to co-locate multiple systems.
Antenna polarization can be used to overcome interference.
3.1.1 Antenna selection
The antenna type must be selected before the system is to be installed. The chosen
antenna must enable the system to operate with sufficient link fade margin without
excessive cost and allow the user’s ‘link availability requirements’ to be met.
The main consideration when selecting an antenna is antenna gain measured in dBi.
A path loss analysis is highly recommended to determine the antenna gain needed for
adequate fade margin. The table below shows antenna selection guidelines for some
configurations. The distances are calculated for a 20 dB link fade margin.
To reduce potential radio interference to other users, the antenna type and its gain
should be so chosen that the equivalent isotropically radiated power (EIRP) is not
more than that required for successful communication.

3.2 Site Evaluation
When planning a site for a digital radio link, it is of the utmost importance that you take
the operational environment of the proposed site into account.
The combined effect of atmospheric environmental factors such as rain and lightning,
atmospheric attenuation, signal path obstruction, propagation fading, air temperature
gradients, ice build-up, wind and solar radiation can contribute towards reducing the
level of performance of the system. The 2.4 GHz and 5.8 GHz bands are not adversely
affected by rain, ice or snow. Severely cold and excessively warm climatic conditions
outside the scope of the operating temperature range can affect the function of the
system, especially the outdoor equipment (see Environmental Characteristics on page
50 of this manual).
Also, if masts are not sufficiently rigid, very strong winds can affect the antenna beam
alignment and Outdoor equipment reliability due to wind force build-up and/or vibration
of the mast-mounted equipment.
3.3 Multipath Effects
The effects of multipath propagation can influence the radio. Understanding these
effects will help when installing a radio link and maximise the reliability of the link.
Multipath fading occurs when the receiving antenna receives not only the direct signal
from the transmitting antenna but also a signal from the transmitting antenna that has
reflected off the ground or nearby obstacles. The reflected signal takes a longer path to
reach the receiver and acts as interference since it is not in-phase with the direct path
signal. The amplitude of the interference can be almost equal to that of the direct path
signal, thus degrading the performance of the link.
Multipath propagation is dependent on transmit frequency and the specific geometry of
the link such as antenna heights, distance between the antennas and the local terrain.
To counteract multipath propagation, the installer can change the frequency at which
the link operates or adjust the height of one or both of the antennas.

3.4 Interference Considerations
The ISM frequency bands are used by other devices that can cause interference to the
MDR / Orion radio systems. Interference can be avoided by careful planning of the
system installation. The available methods for providing isolation from interfering
radiators are the following:
• Frequency diversity
• Antenna polarization
It is recommended to scan the proposed installation areas with a spectrum analyzer
prior to installation to establish the presence of interference. The spectrum analyzer
feature available on the NMS / GUI may also be used. If interference is detected on
the path, the GUI, via laptop connection, can be used to select a new channel plan (A,
B, or C) to “steer around the interferer, or to create a new custom channel plan (Plan
D) to avoid the interference. SNMP network architecture, if employed, may also be
used to make the frequency plan changes. The frequency spectrum should be
scanned over a sufficient time period to ensure that periodic transmissions are
recorded.
Interferers will cause problems if their amplitudes are not more than 20 dB below the
intended receive power level. A link path loss calculation should be performed to
determine the expected receive power level.
The procedure for selecting the optimum antenna polarization and system frequency
plan is the following:
• Perform a spectral analysis at each site in the link direction using a high gain
antenna.
• Repeat the spectral analysis for vertical and horizontal polarization.
• Select the polarization with the lowest interfering levels as the system antenna
polarization.
• Consult the MDR / Orion frequency channel plans as shown in section 2.2.1 and
select the frequency plan that would operate in an interference-free band.
• Install the ‘High Band’ and ‘Low Band’ RF Units at the sites where they would
experience the lowest interference in their respective receive bands.

862-01881 Issue 12c Page 28
3.5 Microcell Backhaul Applications of MDR / Orion Digital Radios
In applications where more than one independent and separate links, need to radiate
from a central site, a number of parameters can be taken advantage of, to provide
isolation and minimise interference between these links:
• Frequency multiplexing
• Antenna polarization
• Choice of High Antenna Gain
It is important to note that these methods only provide isolation between two radio
Systems, and that power levels in the separate systems should be balanced to ensure
correct operation.
3.5.1 Setting the Transmitted Power Levels
To minimise interference, received power levels should be balanced between separate
radio links. This means that transmit power levels should be set to provide similar
levels of received power, as indicated by the RSSI values of the adjacent receivers at
the central site. Power levels are easily adjusted via point and click selection utilizing
the provided NMS / GUI, installed on your laptop or via SNMP network architecture.
3.5.2 Frequency Multiplexing
The MDR2400 and Orion2410i offers three frequency channel plans, the MDR5800
and Orion5810i four and the Orion 5850 also four. Refer to paragraph 2.2.1 for more
detail on the frequency channel plans. A radio link requires two channels (one for
transmit and one to receive) to provide full duplex operation. Each radio has a high
and a low sub-band, one that it uses for transmission and another for reception.
Terminology definition: the ‘High-band RF Unit’ of a system transmits on the higher of
the two sub-bands. The ‘Low-band RF Unit’ of a system transmits on the lower of the
two sub-bands. A system (link) always has one High Band and one Low Band RF
Unit. It is important to note that unwanted transmitted signals in adjacent frequency
bands can affect other receivers operating in an adjacent band if insufficient antenna
isolation is provided. A solution is to group high-band or low-band RF Units at the
central site, rather than group high and low-band RF Units together.
3.5.3 Antenna Isolation
Separate links at a central site will have sufficient isolation when radio systems
operate outside the radiation beamwidth or side lobes of the system antenna. The
achievable isolation can be established by examining the measured radiation patterns
of the system antennas. Directional isolation can be used if the antenna radiation is
15 dB or lower relative to the adjacent main beam. Antennas with high directionality
will allow reduced angular separation of adjacent systems. Antenna cross-polarization
isolation can be used for adjacent radio links, radiating in the same direction. Typical
isolation of 30 dB can be achieved using high quality antennas.

4 Installation
This chapter describes a recommended installation procedure for the MDR2400,
MDR5800, Orion2410i, Orion5810i and the Orion 5850.
Before installation / departure to site
1. Carefully open all shipping boxes and look for any obvious damage that might
have resulted during shipment.
2. Do an operational bench test to verify the functionality of the system.
3. Confirm that both radios have the correct IP configuration (refer to page 108,
paragraph C.2) for "local" and "remote" sites. Use the provided NMS / GUI
installed on a laptop / PC to configure / analyze the radio via a serial / ethernet
connection to the DIU element manager port. Local and remote IP addresses
labels may be fitted to the DIU’s and can be verified with those listed in the GUI.
4. Both radios should be on the same channel plan (paragraph 2.2.1) and power
should be set to an appropriate test level (not muted).
5. NOTE Use at least 60dB attenuation when directly connecting two RFU RF ports.
6. After initial power up and a minute or so of “settle time”, clear any flashing LEDs
via the front panel reset button (paragraph 2.3.4) or the GUI. The DIU status
LEDs should be green with no errors indicated and remain green for an
appropriate time span (at least 1-2 minutes).
7. After satisfactory results, disconnect the units and transfer to the installation site
for permanent installation.
NOTE It is recommended that the installer have previous experience in installing radio
communication equipment or has attended a training course from the supplier for the
purpose of understanding how to set-up and configure an MDR / Orion radio.
Recommended installation procedure
1. Install the Digital Indoor Unit.
2. Prepare and connect the cables to the Digital Indoor Unit.
3. Install the RF Unit and antenna.

4.2 Digital Indoor Unit
4.2.1 Introduction
This section describes the recommended installation procedure for the Digital Indoor
Unit. The Digital Indoor Unit is designed for mounting in the DIN 41494 (19") racking
standard and occupies a 1U high slot. Desktop mounting is also possible.
The Digital Indoor Unit’s payload (nT1, nE1 and 10BaseT Ethernet) and Service
Channel (‘Wayside serial’) data interfaces and Element Management interface are
located on the front panel. Input Power, Auxiliary alarm and ‘DIU/RFU Interconnect’
interfaces are located on the rear panel for the MDR DIU, suitable for rack installations
and on the front panel for the Orion DIU, simplifying accessibility.
The recommended installation procedure for the Digital Indoor Unit is the following:
1. Install the Digital Indoor Unit in the rack.
2. Ground the Digital Indoor Unit. This is required for safety and to minimise radiated
emissions.
3. Connect the DC power supply. There is no ON/OFF switch on the Orion DIU, thus
connecting the DC power supply will start up the radio.
4. Connect Payload data ports (front panel).
5. Connect Auxiliary In/Out port (optional).
6. Connect Service Channel (Wayside) serial port (optional).
7. Connect the Element Manager port using the supplied cable (front panel).
4.2.2 Installing the Digital Indoor Unit in a Rack
1. Slide the Digital Indoor Unit into the 19" rack and secure to the rack using four (4)
APPROPRIATELY sized bolts for size and rack threads provided. M6 x 18 mm

4.2.9 Connecting the Element Manager Port
The Element Manager port is used to connect the Digital Indoor Unit to a PC/Laptop
serial port. This enables the Digital Indoor Unit to be configured using the supplied
NMS / GUI software or controlled via a PPP-dialup connection. The port can be
connected to using the supplied serial data cable. The port is configured as DTE.
NOTE The Ethernet 10BaseT port can also be used to control the DIU via the GUI /
SNMP software.
4.3 RF Unit
The MDR2400 and MDR5800 outdoor RF Units are also available as 1U indoor RF
Units, Orion2410i and Orion5810i, that can be rackmounted in a 1U rack.
Before installing the Orion or MDR RF Unit, ensure that a suitable mast is used for the
antenna and that the RF Unit installation is firmly in position. The pole diameter must
be between 50 and 102 mm or between 2" and 4½".
The outdoor unit type RF Unit may also be mounted indoors, utilizing an optional rack
mount adapter (not included as a standard item) at the base of a tower for convenient
access. However, this as not recommended as a long and expensive RF cable would
then be required, compromising system sensitivity and increasing link costs.
CAUTION – ENSURE THAT THE POLE IS EARTHED FOR
LIGHTNING PROTECTION.
Follow these steps to install the RF Unit:
1. Install the system antenna.
2. Adjust the mounting bracket to be slightly bigger than the pole diameter.
3. Secure the mounting bracket to the pole.
4. Secure the RF Unit to the bracket using the screws on each bracket.
5. Connect the RF Unit to the pole electrically by connecting the earth cable or strap
between the pole earth and the RF Unit earth point.
6. Connect the type-N RF output connector to the system antenna through an in-line
lightning protection unit in areas with lightning activity.
7. Cover the connectors using an ultra violet protective, self-vulcanising tape.
4.3.1 RF Connection
1. The RF port is an N-type female connector.
2. The N-Type connector is used to connect to the antenna, typically using coaxial
transmission line.
3. 1/2" or 5/8” coaxial cables are recommended. Coaxial cable that is 7/8” or larger
can exhibit moding at 5.8 GHz and is not recommended for 5.8 GHz radios.
MDR2400/5800-SR, Orion2410/5810-SRi and Orion 5825-SR
862-01881 Issue 12c Page 37
4. Do not use right angle N-type connectors with the radios: they may present high
loss.
5. Do not use low quality cables. Some cable types, such as RG-8, may have too
high a loss at 5.8 GHz.
4.4 Interconnection Cable Installation
Follow these steps to install the Digital Indoor Unit to RF Unit interconnection cables.

5 Antenna Alignment and Software Setup
This chapter describes the procedure for software setup and antenna alignment. The
setup is done with a laptop / PC running the supplied NMS Graphical User Interface
(GUI) software. See chapter 6 for details on using the NMS / GUI.
5.1 Installation Equipment Required
The following tools and instruments are required for software setup and aligning the
antenna:
• RSSI test cable
• Voltmeter
• Wrench / spanner (see appropriate details in installation chapter depending on the
antenna being used)
• PC with NMS software and supplied serial data cable.
• Binoculars (optional) used for locating the far end site. This will assist in the
antenna alignment operation.
• GPS or Standard Compass (optional) used for locating the far end site. This will
assist in the antenna alignment operation.
• Bit Error Rate Tester and connecting leads.
5.2 Information Required
You should know:
• the proposed frequency channel plan for each station.
• the expected receive level based on the chosen system configuration and a path
loss analysis.
B.1 Antenna Alignment
5.2.1 Introduction
The RFU should be installed on both sites before alignment starts. Perform the
following steps at both stations:
1. Switch the Digital Indoor Unit power ON.
2. Install and run the NMS Software application.
3. Configure the radio channel plan as required.
4. Set the transmitted power to maximum.
5. Perform a RF loopback test at each site before starting the alignment
procedure.
5.2.2 Alignment Procedure
1. Locate the far site and point the antenna to the antenna at the far site, as
accurately as possible using binoculars or a compass.
2. Connect the multimeter to the RSSI connector on the RFU using the supplied
RSSI test cable and set the multimeter to measure volts.
3. Check the RSSI level and refer to the figure below for received power level.
4. Align the antenna until the maximum RSSI is attained.
MDR2400/5800-SR, Orion2410/5810-SRi and Orion 5825-SR
862-01881 Issue 12c Page 41
5. Secure the antenna.
6. Measure the RSSI level and record the value (see section 5.6).
7. Compare with the value with that calculated for the link i.e. using the path loss
calculation done when planning the link.

-30 dBm Average 1.333 ± 0.047 V : MIB RSSI 54 ± 2 dBm (see comment below)
The front panel RF Link LED, the Received Signal Strength Indicators (RSSI : on
NMS, via SNMP or as an Electrical signal on the RF Unit), Carrier-detect (NMS,
SNMP) and Frame Lock (NMS, SNMP) indicators are available to assist with link
installation and alignment.
NOTE 1 The MIB lists a value representative of the received signal level in [-dBm].
This value corresponds to the signal power measured in a 200 kHz BW centred at the
receive frequency of the radio.
When not in spectrum analyser mode, the Orion RFU translates the measured signal
power to a value corresponding to the wanted signal power in the receiver bandwidth.
NOTE 2 For the MDR and Orion10i RFUs, the RSSI values displayed in the MIB are
representative of the signal level measured over a 200kHz BW. Add ~20dB to the MIB
value for a wanted spread spectrum signal. The NMS / GUI will do this adjustment
automatically and will therefore always display the correct RSSI value.
NOTE 3 Due to the technique used to calculate the RSSI level of a wanted signal, the
measured RSSI level can differ from the actual value with up to ±3 dB.

5.2.3 Set Transmitted Power Level
It is good practice to match received power levels by adjusting transmitted powers if
co-located systems are being installed. This is important to avoid interference
between co-located systems. An attenuator can be fitted between the RF Unit and the
antenna if the power level cannot be sufficiently reduced. The dBm output at the RFU
N-type connector (socket) levels are set via the NMS or using a SNMP Management
application.

5.3 Software Setup
Refer to chapter 6, for setting up the following:
• Payload interface.
• Service Channel (Wayside) serial port.
• Auxiliary in/out port.
• General link parameters.
5.4 Functional Test
After completing the physical installation of the Digital Indoor Units, antennas, RF
Units and the interconnection cables, you need to commission the system. This
procedure describes how to set up the minimum requirements for successful MDR /
Orion system operation.
5.4.1 Link Bit Error Rate Performance Test
To start : when the link is setup correctly, the RF Link LEDs on both DIUs on both
sides of the RF link should be GREEN.
When the link has been setup and is running error-free:
1. Clear the Digital Indoor Unit Log using Reset Button Position ‘2’
2. Clear the Digital Indoor Unit Errors using Reset Button Position ‘1’
Perform a link bit error rate performance test as follows:
• Connect a bit error rate tester to the payload interface of the link.
• Run data over the link for a period of 24 hours.
• Record the BER.
• Record the LED statuses.
Check the Digital Indoor Unit Packet Error Results via the NMS or via SNMP access to
the Digital Indoor Unit MIB – for the NMS, right-click on the antennas in the NMS for
either side of the link and select the “Diagnostic/Error Monitor” option. Record the
results by saving the data to a file. For SNMP access, use a MIB Browser and check
the mdrmteRFLinkPerf and mdrmteG826 Performance groups.
Record all results on a test record. See MDR / Orion Test Record, section 5.6 for an
example.

6 NMS Software
6.1 Scope
This section provides minimal information required to install the Orion NMS. A detailed
HTML-based help document can be found on the NMS installation CD supplied with
new radios.
6.2 Introduction
The purpose of the Network Management System, hereafter called the NMS, is to
allow you to configure, manage or interrogate the following primary functional
elements of a Digital Radio Link:
• Digital Indoor Unit
• RF Unit
A Digital Radio Link consists of two Indoor-RF Unit stations connected through a radio
link.
The Orion NMS is designed to auto-detect the radio type it is connected to and can
support the following radio types:
• Orion XX
• MDR XXXX
Since the firmware and software for the MDR XXXX and the Orion XX10i RFUs are
exactly the same, the NMS has no means to detect the difference between these
units. The NMS will therefore always display the radio type as MDR XXXX.
The NMS is a PC-based software package that provides you with a graphical interface
that is used to perform on-site element management of a digital radio system. It
allows you to configure, manage and interrogate the system by selecting various
menus and options.
The hardware as well as the software constituting the NMS is collectively called the
NMS Terminal.
The NMS Terminal is the principal system support equipment associated with the radio
for system installation and commissioning.
The NMS connects to a designated NMS Terminal port (labelled Element Manager) on
the front panel of the Digital Indoor Unit, by means of a serial data interface (this cable
is supplied in the DIU box). It can also connect to any number of Digital Indoor Units
interconnected through an IP network.
The NMS communicates with SNMP agent software that is contained in each Digital
Indoor Unit. The NMS communicates with the agent’s software: the software enables
a unit to interpret MIB (Management Information Base) commands via SNMP (Simple
Network Management Protocol).
MDR2400/5800-SR, Orion2410/5810-SRi and Orion 5825-SR
862-01881 Issue 12c Page 47
NOTE The NMS application supplied with older MDR radios have been replaced with
the Java-based Orion NMS. The older NMS does not support the Orion series radios
and it is highly recommended to replace this NMS with the Orion NMS.
6.3 System requirements

6.4 Installing the NMS
The NMS have been developed on the Java platform from Sun Micro Systems. This
requires the installation of a Java Runtime Environment (JRE) on the PC from where
the NMS will be used.
The installation files for the NMS and the JRE are provided on the installation CD that
is shipped with each radio.
The supplied installation files allows the NMS to be set up on any WIN32 system
(Windows 98, NT, 2000, XP). If required, a special installation can also be provided
which would allow the NMS to be installed on a system using a Linux operating
system.

Complete the following steps to set up the required JRE on the required PC:
• Browse to the //OrionNMS/JRE folder in the root of the installation CD
• Execute the j2re-1_3_1_02-win.exe installation application
• Follow the user prompts in the JRE installation application to set up the JRE in the
preferred folder on the PC
6.4.2 NMS Installation
After installing the JRE on the PC, complete the following steps to install the NMS on
the PC:
• If a previous version of the Orion NMS have been installed on the target PC, first
uninstall the older version
