1 INTRODUCTION
1.1 MDR5800 Description
The MDR5800 is a 5.8 GHz digital radio system that provides short to medium range,
point-to-point digital communication with high data security at rates of E1, 2E1 or 4E1.
Alternatively, the radio can be software configured to convey T1, 2T1 or 4T1. The
radio can also be configured to bridge or route IP via a 10BaseT Ethernet port. The
data rates scale depending on the number of enabled E1/T1 tributaries and whether
the data is being bridged or routed. The product makes use of spread spectrum
technology and may be operated license-free in the 5.8 GHz ISM band. It is ideal for
applications such as:
• Telecommunications companies, cellular operators and private carriers.
• Cellular/PCS base station interconnects.
• Internet distribution.
• Video surveillance data distribution.
• Rural communications.
The MDR5800 consists of two main parts:
• An Outdoor Unit operating in the 5.8 GHz ISM frequency band.
• An Indoor Unit, available with a Telecommunications (1, 2 or 4E1 or 1, 2 or
4T1) interface and a Data interface (10BaseT Ethernet).
Interconnection between the Outdoor Unit and 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 MDR5800 series product uses a split Indoor Unit
and Outdoor Unit configuration for lowest loss between the antenna and the
transceiver, thereby ensuring optimal long-range performance.

2 TECHNICAL DESCRIPTION
2.1 System Overview
A MDR5800 digital radio link (DRL) consists of a pair of MDR5800 radio stations.
The MDR5800 radio station consists of two main parts:
• An Outdoor Unit operating in the 5.8 GHz ISM frequency band. The Outdoor Unit
provides the radio transceiver functionality by accepting radio link data from the
Indoor Unit and converting it to the 5.8 GHz ISM frequency band using spread
spectrum modulation. The received signal is de-spread and transmitted to the
Indoor Unit in a digital format.
• An Indoor unit, available with 1, 2 or 4 E1 and 1, 2 or 4 T1 data interfaces (choice
of E1 or T1 is software selectable). The Indoor Unit combines nE1 or nT1 data
with Wayside Service Channel serial data and link IP data to be transmitted
across the radio link. The Indoor Unit also provides power to the Outdoor Unit.
Interconnection between Outdoor Unit and Indoor Unit is achieved using low cost data
and power cables.
2.2 Outdoor Unit
The MDR5800 Outdoor Unit makes use of Spread Spectrum modulation technology
for license-free operation in the 5.8 GHz ISM band.
For MDR5800 operation, the 5.8 GHz ISM band is divided into upper and lower
frequency sub-bands. An MDR5800 ‘High Band’ Outdoor Unit transmits in the higher
frequency sub-band and receives in the lower frequency sub-band, while a ‘Low Band’
Outdoor Unit transmits in the lower sub-band and receives in the higher sub-band. An
MDR5800 radio link will use a ‘Low Band’ Outdoor Unit on one end of the link to
communicate with a ‘High Band’ Outdoor Unit on the other end.
The MDR5800 Outdoor Unit uses a Type-N RF output connector for connection to any
5.8 GHz antenna for applications where long range is required.
The system is available for use in FCC regulated countries.

2.2.1 Frequency plans
The MDR5800 Outdoor Units operate in the 5.725 GHz to 5.850 GHz ISM frequency
band. The MDR5800 has predefined frequency channel plans (termed A, B, C and
D).
2.2.1.1 Frequency Channel Plan A, B and C
Transmit-to-receive channel spacing for frequency channel plans A, B and C is 69
MHz. 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 Outdoor Units of a link must be set up
to the same frequency channel plan (i.e. A, B or C).

Frequency Channel Plan D
Frequency plan D allows independent control of transmit and receive frequencies.
This enables a very flexible frequency plan and can be used to overcome interference
in the 5.8 GHz ISM band.
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 and the chosen frequencies are 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 2.

3 PLANNING
This chapter is aimed at management and planning staff to enable them to assess the
requirements for installing an MDR5800 digital radio link.
3.1 System Type Selection
The MDR5800 system uses an Outdoor Unit with a type-N RF output for connection
to a range of antennas.
The MDR5800 is aimed at FCC regulated markets.
Antenna polarisation can used to co-locate multiple MDR5800 systems.
Antenna polarisation can be used to overcome interference.
3.1.1 Antenna selection (MDR5800)
The antenna type must be selected before the MDR5800 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.

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. In the higher frequency bands, rainfall is the
main attenuation mechanism that limits error performance. Ice and snow will have a
similar effect. 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 64 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 MDR5800 digital radio operates at frequencies close to 5.8 GHz and can be
influenced by the effects of multipath propagation. Understanding these effects will
help when installing an MDR5800 digital 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 devices that can cause interference to the
MDR5800 radio system. 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 polarisation
It is recommended to scan the proposed installation areas (spectrum analyzer) to
establish the presence of interference. 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 polarisation 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 polarisation.
• Select the polarisation with the lowest interfering levels as the system antenna
polarisation.
• Consult the MDR5800 frequency channel plan as shown in section 2.2.1 and
select the frequency plan that would operate in an interference-free band. Give
preference to channel plans A, B and C as these are optimised for best receiver
sensitivity.
• Install the ‘High Band’ and ‘Low Band’ Outdoor Units at the sites where they
would experience the lowest interference in their respective receive bands.

3.5 Microcell Backhaul Applications of MDR5800 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 polarisation
• 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.
3.5.2 Frequency Multiplexing
The MDR5800 offers four 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 Outdoor Unit’ of a system transmits on the higher of the two sub-bands. The ‘Low-band
Outdoor 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 Outdoor 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 Outdoor
Units at the central site, rather than group high and low-band Outdoor 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-polarisation 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.

5 ANTENNA ALIGNMENT AND SOFTWARE SETUP
This chapter describes the procedure for software setup and antenna alignment. The
setup is done with a PC running the supplied NMS software. See chapter 6 for details
on using the NMS software.
5.1 Installation Equipment Required
The following tools and instruments are required for software setup and aligning the
antenna:
• RSSI test cable
• Voltmeter
• 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
pathloss analysis.
5.3 Antenna Alignment
5.3.1 Introduction
The MDR5800 should be installed on both sites before alignment starts. Perform the
following steps at both stations:
1. Switch the Indoor Unit power ON.
2. Install and run the MDR5800 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.
MDR5800 User Manual
862-01881 Issue 6 Page 37
5.3.2 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 Outdoor Unit 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.
5. Secure the antenna.
6. Measure the RSSI level and record the value (see section 5.7).
7. Compare with the value with that calculated for the link i.e. using the pathloss
calculation done when planning the link.
Figure 5. RSSI as a function of RF input level
The front panel RF Link LED, the Received Signal Strength Indicators (RSSI : on
NMS, via SNMP or as an Electrical signal on the Outdoor Unit), Carrier-detect (NMS,
SNMP) and Frame Lock (NMS, SNMP) indicators are available to assist with link
installation and alignment.
5.3.3 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 Outdoor Unit
and the antenna if the power level cannot be sufficiently reduced. The dBm output at
the OU N-type connector (socket) levels are set via the NMS or using a SNMP
Management application.

• Payload interface.
• Service Channel (Wayside) serial port.
• Auxiliary in/out port.
• General link parameters.
5.5 Functional Test
After completing the physical installation of the Indoor Units, antennas, Outdoor Units
and the interconnection cables, you need to commission the system. This procedure
describes how to set up the minimum requirements for successful MDR5800 system
operation.
5.5.1 Link Bit Error Rate Performance Test
To start : when the link is setup correctly, the RF Link LEDs on both IUs on both sides
of the RF link should be GREEN.
When the link has been setup and is running error-free:
1. Clear the Indoor Unit Log using Reset Button Position ‘2’
2. Clear the 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 Indoor Unit Packet Error Results via the NMS or via SNMP access to the
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.

6 NMS SOFTWARE
6.1 Introduction to the Network Management System
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 (Local or Remote Stations within the link):
• Indoor Unit
• Outdoor Unit
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 Microwave Digital Radio
(MDR) System. It allows you to configure, manage and interrogate the MDR System
by selecting various menus and options.
It provides extensive management functions on site and, via the microwave radio link,
can be used to access the remote MDR station.
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 MDR
System for system installation and commissioning.
It connects to a designated NMS Terminal port (labelled Element Manager) on the
front panel of the Indoor Unit of a MDR Station installation, by means of a serial data
interface (this cable is supplied in the IU box).
The NMS communicates with SNMP agent software that is contained in each
MDR5800 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).
6.2 General Information
1. To select a button/option, simply click the appropriate button/option.
2. Move the mouse pointer to the different areas of the screen. When the pointer
changes into a hand, this indicates that the area can be activated by a left

Link Unavailable The RF Link is considered not available (see Link Availability definition
on next page).
Frame Unlock RF link only. It looks at data received from the link. If the link is quality
is poor, i.e. high PER at the RF level, ‘Frame Unlock’ is the result. AIS
is sent from the transceiver (from link direction) as long as ‘Frame
Unlock’ is true and no reliable data is available.
Packet Error Rate
Fault The PER Monitoring has been enabled and the Instantaneous PER has
exceeded the configured PER Fault Threshold for the RF link.
ESR Exceeded RF Errored Second Ratio has been exceeded due to Packet errors on
the RF link.
SESR Exceeded RF Seriously Errored Second Ratio has been exceeded due to Packet
errors on the RF link.
BBER Exceeded RF Background Block/Packet Errors Ratio has been exceeded due to
block errors on the RF link.
Default RF
Parameters
Activated
The Operational RF parameters were programmed into the Outdoor Unit
by the local and remote Indoor Units. Communication between the two
Indoor Units has not reactivated within 5 seconds. To recover
communication the Indoor Unit has selected the ‘Default’ RF parameters
and programmed the Outdoor Unit with them.
6.7.2 Packet Error Rate Thresholds
Packet error rate (PER) is calculated as the ratio of the number of uncorrectable
blocks over the number of blocks transmitted per second. Three PER thresholds are
provided for each monitored link, these are:
• Minor PER Threshold – this threshold defaults to 0.0002 and triggers an alarm
if the calculated PER exceeds this value.
• Major PER Threshold – this threshold defaults to 0.02 and triggers an alarm if
the calculated PER exceeds this value.
• Fault PER Threshold – this threshold defaults to 2.0 and triggers an alarm if
the calculated PER exceeds this value.
MDR5800 User Manual
862-01881 Issue 6 Page 59
6.7.2.1 G.826 Thresholds
Three G.826 thresholds are provided for each monitored link. Each of these ratios is
calculated once every second and will trigger a fault condition if the ratios exceed the
programmed thresholds that are:
• Errored Second Ratio Threshold – this threshold which defaults to 4 X 10-2 triggers
an alarm if the calculated ESR exceeds this value over the measurement period
(Report Time).
• Severely Errored Second Ratio Threshold – this threshold which defaults to 2 X 10-
3 triggers an alarm if the calculated SESR exceeds this value over the measurement
period (Report Time).
• Background Block Error – this threshold which defaults to 6.25 X 10-2 triggers an
alarm if the calculated BBER exceeds this value over the measurement period
(Report Time).
6.7.2.2 Link Availability
A period of unavailable time begins at the onset of ten consecutive SES events.
These ten seconds are considered to be part of unavailable time. A new period of
available time begins at the onset of ten consecutive non-SES events. These ten
seconds are considered to be part of available time. The figure below illustrates this
definition.
6.7.3 RF Link Error Monitor
The Link Error Monitor screen provides the user with detailed Packet Error Rate
(PER), G.826 and link availability monitoring for the RF link. There is a status field,
Total Seconds, which applies to the link. Total Seconds is the total number of
seconds since the counts were last cleared. It is used to determine available and
unavailable seconds on a link.
6.7.3.1 General
• Errored Blocks Counter - containing the number of blocks containing errors
accumulated until cleared.
• Errored Seconds Counter - containing the number of seconds containing
errored blocks since the counters were last cleared.
MDR5800 User Manual
862-01881 Issue 6 Page 60
• Severely Errored Seconds Counter - a counter containing the number of
seconds containing more than 30% errored blocks since the counters were last
cleared.
• Background Block Errors Counter - a counter containing the number of
blocks received in error excluding those contributing to severely errored
seconds since the counters were last cleared.
• Error Second Ratio – a ratio of the number of Errored seconds to the total
number of seconds since the counters were last reset.
• Severely Error Second Ratio – a ratio of the number of Severely Errored
seconds to the total number of seconds since the counters were last reset.
• Background Block Error Ratio – a ratio of the number of Background Blocks
in errors to the total number of blocks received since the counters were last
reset.
• Corrected Symbols field shows the number of symbols that have been
corrected by the FEC device within the Indoor Unit.
6.7.3.2 Packet Error Rate
• Instantaneous Ratio - This is the number of errored blocks as determined by
the FEC on the RF Link, divided by the total number of blocks per second for
that link. If the instantaneous PER exceeds the minor or major PER
thresholds, a fault is triggered and a RF Link error is indicated on the Indoor
Unit Front Panel.
• Maximised Ratio - The highest Packet error rate reached since the errors were
last cleared.
6.7.3.3 Link Availability
• Available Seconds – the number of seconds the link has been available since
counts were last cleared.
• Unavailable Seconds – the number of seconds the link has been unavailable
since counts were last cleared.

10 APPENDIX B: MANAGEMENT OF THE MDR5800
All management of the MDR product is implemented using SNMP (Simple Network Management
Protocol), an open standard. The MDR5800 product can be managed by:
1. Standard SNMP managers such as HP OpenView or SNMPc i.e. there is Open Network
Management compatibility.
2. For rapid product installation, the NMS GUI Application (hereafter referred to as the NMS-
GA) provides extensive management functions on site and, via the microwave radio link,
can be used to access the MDR station on the opposite side of the link. The MDR5800
NMS-GA is a software application that runs on a PC workstation such as a laptop or
notebook computer that is connected to an MDR 5800 Indoor Unit (IU) serial port (DB9
DTE) or an Ethernet connection (10BaseT DTE) (both accessed via the IU front-panel).
10.1 SNMP and the MDR5800
Use of SNMP within the product allows remote: configuration, monitoring of performance,
notification of alarms and firmware upgrades via an IP-network. Within an IP network supporting
routing of IP data, the radios can be supported from any remote location. The product can be
accessed via the Internet if the necessary gateways are provided. A GSM/PCS modem dial-up
capability provides another remote management option.
The MDR Indoor Units have built-in SNMP agents and an extensive MIB (Management
Information Base). The MDR5800 product uses SNMP V1 (RFC1155, 1157). The user has access
to an Enterprise MIB (obtainable though customer services) and MIB II (RFC 1213).
Access to the MIB via the IU SNMP agent is via Ethernet (10BaseT interface on the product's front
panel) or PPP (RFC 1661) via the product's serial channel Element Manager port. The use of
SNMP provides flexibility for operators with central equipment monitoring. It provides
management access to radio configuration (all data interfaces), interface status and statistics, fault
and maintenance information.
SNMP security (if enabled) is ensured by using a login and password to give the user administrator
or basic user rights (a standard user rights option limits the ability to SET MIB variables).
The product has threshold-based alarm generation (there is an extensive SNMP trap list with a
trap filter that is adjustable via SNMP). Network access (wired or wireless i.e. GSM/PCS Modem)
allows over-the-air remote firmware uploading (FTP) with a load verification (and reversion)
capability.

There are three principle requirements to use SNMP with the MDR5800 Radio Stations.
1. A Management Station that runs a SNMP Management Software package that is installed
on a networked or stand-alone PC that can be connected to an Indoor Unit either using a
serial connection or an Ethernet connection. From the Management station, the agents
within the MDR Indoor Units can be configured or polled for information.
2. Agent: The agent accepts SNMP GET, SET or GET-NEXT commands from the
Management Application software and collects or adjusts information from the Indoor
Unit's MIB.
3. Management Information Base (MIB): the MIB is a database that is accessed based on the
OID (object ID) the SNMP Manager has chosen. The MDR Indoor Unit used an Enterprise
MIB and a standard MIB (MIB II) to store or allow access to information relevant to the
MDR Link.

1.3.6.1.4.1.1316.1.1.1.2.2.3 mdrmteTxFrequencyPlanD INTEGER read-write Frequency plan D allows independent
control of transmit and receive
frequencies. This enables a very
flexible frequency plan and can be
used to overcome interference in the
5.8 GHz ISM band. 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
and the chosen frequencies are 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 Lower Sub-band -
5735-5771 MHz, Upper Sub-band -
5804-5840 MHz. The user must take
note of whether the radio is a high or
low band unit before choosing a set of
transmit and receive frequencies.
Note also that THE TX AND RX
FREQUENCIES MUST BE
SELECTED BEFORE BAND PLAN D
OPTION IS SELECTED VIA THE MIB.

there is no assistance on the opposite
side of the link. It mitigates against
the link failing and not being able to
be re-established. If “auto recovery” is
enabled, the required operational RF
parameters are programmed into the
Outdoor Units by the local and remote
Indoor Units. If communication
between the two Indoor Units has not
reactivated within 5 seconds, the
previous (working) 'default' RF
parameters are programmed into the
respective Outdoor Units.

12 APPENDIX D: MDR5800 HARDWARE VERSION 1, 2.X
DIFFERENCES, COMPATIBILITY SUMMARY
Version 1 hardware (Indoor and Outdoor Units) is incompatible with Version 2.x hardware.
• The Indoor Unit /Outdoor Unit Twisted Pair Data Interconnection for Version 2 hardware
uses 2 twisted pair cables to convey payload and Outdoor Unit control signals whereas
Version 1 hardware uses 4 twisted pair cables.
Notes :
Version 2.x firmware (can be uploaded into the Indoor Unit using the NMS’s Maintenance option)
that can be used in Version 1.x hardware must be obtained from the product manufacturer. The
file is not the same file that is used with Version 2.x hardware.
Updated RSSI and Power control functionality have been added to Version 2.x hardware and
firmware.
Version 2.x firmware has
1. FTP upload functionality (needs to be activated via the MIB)
2. IP Bridging functionality (half and full duplex – selectable via the MIB)
3. Band Plan C
4. Refer to the MIB section of this manual and look for the † symbol to see what MIB-related
functionality is in place/activated/planned for Version 2.x + firmware.
5. Functional RF Loopback built-in test feature.
Version 2.x NMS has
1. Ability to allow the user to connect to the Indoor Unit using PPP (via a serial cable
interface to the IU’s front panel Element Manager RS232 port) or via Ethernet (via the
front panel RJ45 connector: 10BaseT).
2. Graphical Spectrum Analyzer display
By default, firmware provided for the Indoor Units does not provide a secure login feature (thereby
limiting a user’s ability to ‘set’ MIB variables). Suitably adapted firmware versions (dependent on
hardware version) need to be requested from the product manufacturer to allow activation of this
feature.
