Regulatory Compliance
General Note
This system has achieved Type Approval in various countries around the world. This means
that the system has been tested against various local technical regulations and found to
comply. The frequency bands in which the system operates may be “unlicensed” and in these
bands, the system can be used provided it does not cause interference.
FCC - Compliance
This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable
protection against harmful interference in a residential installation. This equipment generates,
uses and can radiate radio frequency energy and, if not installed and used in accordance with
the instructions, may cause harmful interference to radio communications. However, there is
no guarantee that interference will not occur in a particular installation. If this equipment
does cause harmful interference to radio or television reception, which can be determined by
turning the equipment off and on, the user is encouraged to try to correct the interference by
one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
Consult the dealer or an experienced radio/TV technician for help.
Changes or modifications to this equipment not expressly approved by the party responsible
for compliance could void the user's authority to operate the equipment.
Warning
It is the responsibility of the installer to ensure that when using the outdoor
antenna kits in the United States (or where FCC rules apply), only those
antennas certified with the product are used. The use of any antenna other
than those certified with the product is expressly forbidden by FCC rules 47
CFR part 15.204.
Warning
It is the responsibility of the installer to ensure that when configuring the
radio in the United States (or where FCC rules apply), the Tx power is set
according to the values for which the product is certified. The use of Tx
power values other than those, for which the product is certified, is
expressly forbidden by FCC rules 47 CFR part 15.204.
Caution
Outdoor units and antennas should be installed ONLY by experienced
installation professionals who are familiar with local building and safety
codes and, wherever applicable, are licensed by the appropriate
government regulatory authorities. Failure to do so may void the product
warranty and may expose the end user or the service provider to legal and
financial liabilities. Resellers or distributors of this equipment are not liable
for injury, damage or violation of regulations associated with the installation
of outdoor units or antennas. The installer should configure the output
power level of antennas according to country regulations and antenna type.
RADWIN 2000 User Manual Release 2.5.40 iv
Indoor Units comply with part 15 of the FCC rules. Operation is subject to the following two
conditions:
(1) These devices may not cause harmful interference.
(2) These devices must accept any interference received, including interference that may
cause undesired operation.
Canadian Emission Requirements for Indoor Units
This Class B digital apparatus complies with Canadian ICES-003.
Cet appareil numẻrique de la classe B est conforme ả la norme NMB-003 du Canada.
China MII
Operation of the equipment is only allowed under China MII 5.8GHz band regulation
configuration with EIRP limited to 33 dBm (2 Watt).
India WPC
Operation of the equipment is only allowed under India WPC GSR-38 for 5.8GHz band
regulation configuration.
Unregulated
In countries where the radio is not regulated the equipment can be operated in any regulation
configuration, best results will be obtained using Universal regulation configuration.
Safety Practices
Applicable requirements of National Electrical Code (NEC), NFPA 70; and the National
Electrical Safety Code, ANSI/IEEE C2, must be considered during installation.
NOTES:
1. A Primary Protector is not required to protect the exposed wiring as long as the exposed
wiring length is limited to less than or equal to 140 feet, and instructions are provided to
avoid exposure of wiring to accidental contact with lightning and power conductors in
accordance with NEC Sections 725-54 (c) and 800-30.
In all other cases, an appropriate Listed Primary Protector must be provided. Refer to Articles
800 and 810 of the NEC for details.
2. For protection of ODU against direct lightning strikes, appropriate requirements of NFPA
780 should be considered in addition to NEC.
Warning
• Where Outdoor units are configurable by software to Tx power values
other than those for which the product is certified, it is the responsi-
bility of the Professional Installer to restrict the Tx power to the certi-
fied limits.
• The RADWIN 2000 2.5GHz BAND device (FCC ID: Q3KRW2025) com-
plies with FCC RF radiation exposure limits. This equipment should be
installed and operated with a minimum distance of 104.6cm between
the radiator and your body for 2.5 GHz operations
• This product was tested with special accessories - indoor unit (IDU or
PoE), FTP CAT-5e shielded cable with sealing gasket, 12 AWG
grounding cable - which must be used with the unit to insure compli-
ance.

Figure 1-2: Typical Broadband Access application
Mobility Applications Chapter 1
RADWIN 2000 User Manual Release 2.5.40 1-5
Figure 1-3: Typical WiFi Backhaul Application
Mobility Applications
RADWIN 2000 radios have been successfully deployed in a variety of Mobility Applications:
Border Control
RADWIN 2000 may be used in both towers and patrol vehicles to provide live video surveil-
lance. Handoff from tower to tower as the patrol vehicles moves along the patrol road is
seamless. The towers may be sited several kilometers apart (depending on topography) and
are themselves synchronized using RADWIN GSU.
Installation Security
Securing an installation like a factory or an airport is broadly similar to Border Control, how-
ever the distance are smaller and the towers may be connected to a control room using
cables.
Railway solutions
This is a relatively new application and includes for example,
»On-board surveillance
»On-board monitoring and control
»Passenger services including Internet access
For further information about Mobility Applications, contact RADWIN Customer Support.
Key Features of RADWIN 2000
Some of the outstanding features of the RADWIN 2000 radio series are as follows:
»E1/T1 + Ethernet in one Solution
RADWIN 2000 systems deliver carrier-class native E1/T1 + Ethernet in a single plat-
form, making them ideal for a range of backhaul and access applications. Up to 16 E1/
T1 services are supported for C, L and PDH models.
»High Capacity
The RADWIN 2000 system provides a high-capacity link of 100 Mbps net throughput
full duplex
»Superior Spectral Efficiency
Key Features of RADWIN 2000 Chapter 1
RADWIN 2000 User Manual Release 2.5.40 1-6
Built on advanced MIMO and OFDM technologies, the RADWIN 2000 system provides
a high-capacity link at channel bandwidths of 5, 10 and 20MHz. These channel
bandwidths supports high robustness of the air interface under interference and harsh
conditions.
»Multi-band Products
Every RADWIN 2000 Multi-band radio supports multiple frequency bands. For example
the RW-2050-0250 connectorized radio supports the bands: 5.9 GHz, 5.8 GHz, 5.4
GHz, 5.3 GHz, 4.9 GHz, 2.4 GHz and 3.4-3.7 GHz. The RADWIN 2000 Multi-band prod-
ucts support the regulations of FCC, IC Canada, ETSI and WPC India. DFS is sup-
ported where required by regulation.
»Advanced Air Interface
The RADWIN 2000 system provides an advanced air-interface based on MIMO,
antenna diversity and OFDM technologies, resulting in an exceptionally robust air
interface and high frequency band granularity.
Using the following technologies, the RADWIN 2000 air interface is designed to ensure
nonstop, high quality transmission, even under interference and harsh conditions:
• Automatic Adaptive Rate (AAR) is a mechanism that dynamically adapts the air
interface rate by changing both the signal modulation and coding.
• Automatic Channel Selection (ACS) chooses the best channel by monitoring the
available radio channels and dynamically selecting a channel which is best suited
for transmission at any given time.
• Automatic Repeat Request (ARQ) is a mechanism for error control during data
transmission. When the receiver detects an error in the received information, it
automatically requests the transmitter to resend the information. This process is
repeated until the transmission is error free or the error continues beyond a pre-
determined number of maximum transmissions. RADWIN 2000's ARQ mechanism
is optimized for time-critical traffic.
• Forward Error Correction (FEC) with very low overhead and algorithms specifi-
cally designed for the varying conditions of license-exempt frequency bands,
ensuring fast, robust and error-free communications.
»High transmission (Tx) power
The RADWIN 2000 system supports high Tx power, compliant with radio regulations.
High Tx power increases the system's availability and range, and enables the high
performance with smaller antennas, thus reducing the total cost of the solution (lower
CAPEX), installation and tower rent costs (lower OPEX).
The 5 GHz bands support a maximum Tx power of 25dBm whereas the 2.4 GHz band
supports a maximum Tx power of 26dBm.
»Superior range performance
The RADWIN 2000 system supports high capacity at superior ranges. The Link Budget
Calculator (Chapter 21) is used to determine the capacity and range according to the
choice of product, antenna, type of service and environmental conditions.
»HSS Interoperability between RADWIN 2000 and WinLink 1000
Site Synchronization is supported with any mix of RADWIN 2000 and WinLink 1000
links. RADWIN 2000 can be used to backhaul WinLink 1000 collocated links without
mutual interference
Key Features of RADWIN 2000 Chapter 1
RADWIN 2000 User Manual Release 2.5.40 1-7
»Monitored Hot Standby (1+1):
The RADWIN Monitored Hot Standby (MHS) protects up to sixteen E1/T1 services with
RADWIN 2000 and up to four E1/T1 services with WinLink 1000. It is designed to
provide high reliability high-capacity Point-to-Point Links. The RADWIN MHS
is
-
• Designed to provide redundancy and high reliability for carrier class operators
• Optimized for high capacity links operating in license-free bands
• A comprehensive solution providing protection against both equipment failure
and loss of air interface, by simple connectivity between a primary link and a sec-
ondary link
• Able to use a different band for maximum protection to the air interface
The main
features
of the RADWIN MHS are –
• Cut-over from the primary to the secondary link completely automatic
• Cut-over time no more than 50 ms
• Automatic restore to primary link as soon as it becomes available
• WinLink 1000 can backup a RADWIN 2000 link
A major
benefit
of RADWIN MHS is that is can underpin an affordable Service Level
Agreement structure by protecting part of the RADWIN 2000 trunks with WinLink
1000.
MHS supports TDM services; Ethernet services are carried by both links independently.
»Spectrum View
Spectrum View displays a visual representation of spectrum availability during the
link installation. It is an RF survey tool supporting the link installation prior to service
activation.
Use Spectrum View to assist you to choose the operating channel.
»Diversity
RADWIN 2000 links using dual bipolar antennas may be configured to transmit the
same data through both radios. This feature provides added data transmission integ-
rity under harsh conditions.
»Simple installation and management
RADWIN 2000 systems are extremely simple to install and maintain. They are typically
up and running in less than an hour.
The RADWIN Manager application has full local and remote management capabilities.
The user-friendly SNMP based management tool provides full end-to-end
configuration, event logging, and performance monitoring capabilities.
»Enhanced Security
The security features of RADWIN 2000 include:
• RADWIN 2000's AES 128-bit integrated advanced encryption support provides
enhanced air interface security for carriers and private networks. It ensures user
data protection with one of the most sophisticated commercially available com-
bined encryption and authentication techniques, CCM/AES. This technique com-
bines message authentication (preventing anti-spoofing and replay protection)
with commercial encryption, and complies with the IEEE 802.11i (phase iii) secu-
rity recommendations.
Components of a RADWIN 2000 Link Chapter 1
RADWIN 2000 User Manual Release 2.5.40 1-8
CCM/AES uses a symmetric 128-bit encryption key (EK), and a nonce, and pro-
vides both message encryption and authenticating signature. The nonce mecha-
nism enables the receiver to remember already received genuine messages and
reject all replayed messages.
• Initial encryption and authentication is based on a user-defined master key (Link
Password). While standard Wireless LAN encrypts only the Ethernet Payload, the
AES encrypts both the source and destination MAC addresses.
• In addition to normal log on access, Read or Write Community access is available
at log on
• Link Lock is a part of the RADWIN 2000 security concept. It is designed to dis-
courage physical theft of units and “piggybacking” using an otherwise identical
ODU to steal bandwidth or information. It locks a pair of synchronized ODUs for
mutually exclusive communication.
»SFP support in the IDU-C
Standard SFP modules are used, enabling any type of Ethernet physical connectivity
including various fiber connections. E3/T3 or E1/T1 over Ethernet SFPs can be used as
well.
»Separate management and traffic VLAN support
»Ethernet Ring Topology
»QoS Support (RADWIN 2000 C based links)
QoS enables Operator and Service Providers to offer delay-sensitive services such as
VoIP, IP-TV, time critical applications and online games.

Antennas
An antenna is the radiating and receiving element from which the radio signal, in the form of
RF power, is radiated to its surroundings and vice versa. The antenna gain and transmitting
power may be limited by country regulations.
The RADWIN 2000 may be operated with an integrated antenna that is part of the ODU unit,
or with external antennas connected to the ODU via N-type connectors. All cables and con-
nections must be connected correctly to reduce RF losses. The required antenna impedance
is 50Ω.
The 5.x GHz Integrated Antenna ODU is provided with 370 mm (1.2ft) flat panel antenna,
with a gain of 23dBi (5.x GHz) / 19dBi (4.9 GHz) and 8° beam width. The 2.x GHz Integrated
Antenna ODU is provided with 370 mm (1.2ft) flat panel antenna, with a gain of 16dBi and
16° beam width. The radio and the antenna are housed in a weatherproof case as a single
unit.

A Little Terminology Chapter 1
RADWIN 2000 User Manual Release 2.5.40 1-16
A Little Terminology
In the field, a link typically has a local or headquarters site as for example in Figure 1-1
above. Here the service provider is the local or headquarters site. The service recipient is the
remote site.
Where the link is completely internal to a corporation, the choice of the local and remote is
just a matter of convenience.
A
link
then, consists of two
sites
.
In Broadband Wireless terminology, the local and remote sites are sometimes referred to as
“near” and “far”, “HQ” and “remote” and so on.
The site which is closer to the network core (often the local site) will be referred to as
site A
,
and the opposite side of the link, usually closer to the end user, as
site B
.
This choice is application-neutral and will be used throughout the manual both to describe the
sites and their names as in the examples.
The link is configured and managed using a PC, the
managing computer
connected to site
A. (The precise requirements for the managing computer are set out on page 4-1).
We will occasionally need to distinguish between the site to which the managing computer is
connected, and the second site, when they are not necessarily A or B. The former will be
called the
managing site
and the latter, the
over-the-air site
. Which is which, is always
determined by the location of the managing computer.
RADWIN 2000 supports three connection methods for the managing computer:
•
Local
- a direct peer to peer connection between the Ethernet ports on the managing
computer and the IDU or PoE device. Local connection is always read-write.
•
Network
- the managing computer and the site A IDU or PoE device belong to a LAN
and communicate through a router or switch
•
Over-the-air
- the managing computer connects to site B via the air interface
• The managing computer may be connected to the link through an IDU or a PoE
device. In what follows, where ever we refer to an IDU it includes PoE devices unless
stated otherwise. Typically, if we need to refer to an IDU as such, we will use a model
name such as IDU-C.
The terms uplink and downlink, originate from the field of Satellite communications. In a
backhaul or ISP context, uplink is from the user to the network and downlink is from the
network to the user.

Site Preparation
Planning the Link Site
Overview
Link site planning consists of a set of surveys, which must be carried out before any equip-
ment is brought to the site. If for some reason, the outcome of any of these surveys is nega-
tive, site re-location will need to be considered.
A Site Survey consists of three stages:
1. Preliminary survey - The proposed link is analyzed in the office using a topographic map.
2. Physical survey - The locations of the indoor and outdoor equipment are determined on-
site.
3. Radio Frequency (RF) survey - It is recommended that the installation area be scanned
with a spectrum analyzer, to identify RF interference so as to determine a clear channel for
radio installation (on-site).
The Site Survey
Introduction
RADWIN wireless links must be planned before installation. The designated installation site
must be appraised to determine that the wireless system is able to operate efficiently and
provide connectivity without signal degradation.
RADWIN 2000 offers a wide operating frequency range. A free frequency channel must be
determined within the operating range, for optimum performance.
Recommended Equipment
Stage 1: Preliminary Survey
• Topological map of the area
• Urban map of the area
•Compass
Stage 2: Physical Survey
• 100 meter tape measure
Stage 1: Preliminary Survey Chapter 2
RADWIN 2000 User Manual Release 2.5.40 2-2
• Ohmmeter, to check ground connection
•Binoculars
•Map
• Digital camera
• Paper, pencil, and a clipboard
• GPS device (optional)
• Compass (optional)
Stage 3: RF Survey
• Spectrum Analyzer with Max Hold function and screen capture facility that can store
multiple images, for documentation purposes
• RF accessories (connectors and cables)
• Communication devices (for example, cellular phones, or a set of walkie-talkies)
Stage 1: Preliminary Survey
A preliminary survey is necessary before visiting potential installation sites. As much detail as
possible should be obtained about the two designated ODU installation sites and the area
between them.
To perform a preliminary survey:
1. Mark the two designated installation sites on a topographic map of the area.
2. Measure the distance between the sites; check that it is within the specified range of
the equipment.
3. On the urban map, check for developed areas situated between the two installation
sites. Pay attention to these areas when performing the physical site survey; there
may be tall buildings, RF towers, or transmitters, which could cause interference to
the link.
4. Check the area between the two sites for obstructions such as:
• High ground - hills or mountains
• Lakes or large bodies of water. Water has a reflection effect on RF signals like a build-
ing. This type of reflection causes the received amplitude to be reduced. As a rule of
thumb, the presence of a large body of water between the link sites may double the
required antenna height.
5. Determine and record the compass bearings between both ODUs, relative to north.
6. If there are obstructions between the two sites, calculate the Fresnel Zone (see
Chapter 21 for details).
7. If the site chosen does not meet requirements, consider alternative sites.
8. Use the Link Budget Calculator (on the CD supplied with the equipment or using the
RADWIN Manager) to determine the expected performance.
Stage 2: Physical Survey Chapter 2
RADWIN 2000 User Manual Release 2.5.40 2-3
Stage 2: Physical Survey
The physical site survey reviews the environment of the proposed installation location, to
ensure that the link sites are suitable for the wireless network. The results of the physical site
survey should be recorded.
To perform a physical survey:
1. From the compass readings taken in the preliminary survey, find the azimuth (hori-
zontal position) that the ODU should face towards the second ODU.
2. Using binoculars, locate any obstructions such as tall trees, high buildings, hills or
mountains. Look for other RF towers between the two sites. Mark the locations of
the obstructions on the map.
3. Determine the location for the ODU (having regard for existing rooftop installations
and tower space). It should be above any obstructions, considering the Fresnel zone
(see Chapter 21).
4. If you need to install the ODU on a tower, make sure that the tower is far away from
overhead electric power lines.
5. Determine a location for the indoor equipment; it should be as close as possible to
the ODU. At an existing site, there is probably an equipment room with cable-routing
channels.
6. Measure and record the path length of the cable from the ODU position to the indoor
equipment room.
7. Determine the ground and lightning connection points of the installation. The ODU
and IDU must both be grounded.
8. Using the Ohmmeter, measure and record the resistance of the required installation
to the grounding point. The resistance must be less than 1O ohm.
9. Review the results of the physical site survey. Decide if the site is suitable for the
wireless network installation.
• If the site is suitable, continue with stage 3, the RF survey
• If the site is not suitable, survey another site
Additional Outdoor Site Requirements
The ambient outdoor operating temperature should be -35 to 60C (-31 to 140F).
Additional Indoor Site Requirements
The following requirements guarantee proper operation of the system:
Note
It is advisable to go on a clear day, so you can more easily see any
obstructions between the two sites.
Note
The IDU - ODU cable length limit is 100m, in accordance with IEEE 10/
100BaseT standards.
Stage 3: RF Survey Chapter 2
RADWIN 2000 User Manual Release 2.5.40 2-4
• For IDU-C units, allow at least 90 cm (36 “) of front clearance for operating and main-
tenance accessibility. Allow at least 10 cm (4 “) clearance at the rear of the unit for
signal lines and interface cables
• The ambient operating temperature should be 0 to 50°C (32 to 122 °F) at a humidity
of up to 90%, non condensing
Stage 3: RF Survey
The RF survey examines the wireless environment of the installation site, to determine
whether there are available channels within the radio operating frequency band. An RF survey
is performed using a spectrum analyzer.
It is advisable to familiarize yourself with the spectrum analyzer before going out on site, spe-
cifically the Max Hold and Marker functions.
You should perform the RF survey at both proposed link sites.
The survey should be carried out during a busy time of day, to best judge the worst-case
radio interference. Allow 2-4 hours duration for a good RF survey.
RF Planning for Dense Installations and Collocated Sites
Interference may arise from
• Self interference from collocated RADWIN radios
• Other collocated radio devices installed on the same site.
To avoid or minimize interference, follow these recommendations:
• For collocated RADWIN units, use an HSS unit to synchronize between them. Select a
different operating channels for each collocated RADWIN unit.
• If one or more collocated units are not RADWIN units, ensure that there is a physical
separation of at least three meters between a RADWIN unit and any other collocated
radio on the site.
• Use the largest possible frequency gap between these units.
• Choose the best frequency channel (as clear as possible form interference). You may
change band with “Combo” WinLink 1000 products and all RADWIN 2000 products).
• To select a frequency channel, move the link to Installation Mode (using Site con-
figuration) and start the Installation wizard. In the Channel Settings window, use
the quality bar at the bottom to help you choose a better channel (clearer of interfer-
ence).
• If you are using WinLink 1000 radios, install the collocated links with different antenna
polarizations.
• If you are using the RADWIN 2000 radios, use the Spectrum View tool to find the
best working channel (Tools | Spectrum View).
Note
It is possible to install the link and use the RADWIN Manager to find a clear
channel. Each frequency channel can be evaluated in turn. Achievement of a
clear channel is indicated by the marker in the Quality bar on the Channel
Setting window (see Figure 5-6) moving into the green area.

Chapter 3
Hardware Installation
This chapter sets out the requirements and procedures for the hardware installation and
alignment of a RADWIN 2000 link in accordance with the prior planning as set out in Chapter
2. It is intended to guide qualified field technicians.
Safety Practices
Preventing overexposure to RF energy
To protect against overexposure to RF energy, install the ODUs so as to provide and maintain
minimal separation distances from all persons.
When the system is operational, avoid standing directly in front of the antenna. Strong RF
fields are present when the transmitter is on. The ODU must not be deployed in a location
where it is possible for people to stand or walk inadvertently in front of the antenna.
Grounding
All RADWIN products should be grounded during operation. In addition:
•The ODU should be earthed by a wire with diameter of at least 12AWG.
The RADWIN 2000 ODU must be properly grounded to protect against lightning. It is
the user's responsibility to install the equipment in accordance with Section 810 of the
National Electric Code, ANSI/NFPA No.70-1984 or Section 54 of the Canadian
Electrical Code. These codes describe correct installation procedures for grounding the
Warning
Outdoor units and antennas should be installed ONLY by experienced
installation professionals who are familiar with local building and safety
codes and, wherever applicable, are licensed by the appropriate
government regulatory authorities. Failure to do so may expose the end
user or the service provider to legal and financial liabilities. RADWIN and its
resellers or distributors are not liable for injury, damage or violation of
regulations associated with the installation of outdoor units or antennas.
Note
The material in this chapter is generic to all RADWIN radio link products
unless stated otherwise.

outdoor unit, mast, lead-in wire and discharge unit. It also lays down the size of
grounding conductors and connection requirements for grounding electrodes.
The RADWIN 2000 ODU must be grounded to a Protective Earth as described in
Chapter 18 and in accordance with the Local Electrical Regulations.
• The earth lug on the IDU-C should be connected to the protective earth at all times,
by a wire with a diameter of 18 AWG or wider. Rack-mounted equipment should be
mounted only in earthed racks and cabinets.
Further, you should -
• Always make the ground connection first and disconnect it last
• Never connect telecommunication cables to ungrounded equipment
• Ensure that all other cables are disconnected before disconnecting the ground
More detailed guidelines are supplied in Chapter 18.
Protection against Lightning
The use of lightning protection is dependent on regulatory and end user requirements. All of
RADWIN outdoor units are designed with surge limiting circuits to minimize the risk of dam-
age due to lightning strikes. RADWIN recommends the use of additional surge arrestor
devices to protect the equipment from nearby lightning strikes.
See Chapter 18 for detailed installation instructions of lightning protection devices.
General
• It is recommended that installation of the outdoor unit be contracted to a professional
installer.
• Before working on equipment connected to power lines or telecommunication lines,
you should remove jewelry or any other metallic object that may come into contact
with energized parts.
• Use extreme care when installing antennas near power lines.
• Use extreme care when working at heights.
• When using an AC power source for RADWIN 2000 always use the AC power adapter
supplied by RADWIN.
• Use the right tools. In addition to standard tools required for any kind of ODU or
antenna installation, RADWIN 2000 requires additional specific tools detailed on

Outdoor installation Chapter 3
RADWIN 2000 User Manual Release 2.5.40 3-7
Outdoor installation
Preparing the ODU before Deployment
Each ODU must be pre-loaded with an IP address. This may be done prior to deployment in
the field, or on-site using a Laptop computer. The process is quite straight-forward and
described in Chapter 19.
Mounting the ODU
The ODU can be mounted on a pole or a wall. In both installations, the supplied mounting kit
is used to secure the ODU.
A RADWIN 2000 link operates in pairs of two ODUs with the same configuration. Both ODUs
must be installed, and the antennas aligned for maximum throughput.
To mount the ODU on a pole or a wall:
1. Ensure that the ODU is properly grounded.
2. Mount the ODU onto the pole or wall. Ensure that the unit is oriented so that the
cable connectors are at the bottom. (If they are on top, water may penetrate
into the unit causing damage.) It is possible to mount an ODU horizontally. See
Chapter 17 for details.
3. Refer also to Chapter 17 for detailed ODU mounting kit contents and schematics.
Mounting external antennas
If you are using ODU with an integrated antenna, skip to Mounting the Lightning Protec-
tion Devices below.
The supplied mounting kit is used to mount the antenna onto a pole. The antennas must be
aligned for maximum throughput.
Note
A mast-sited ODU typically uses a pole attached to the mast.
Warning
Prior to connecting cables to the ODU, the protective earth terminal (screw)
of the ODU must be connected to an external protective ground conductor
or to a grounded pole.
• Only a qualified person using the proper safety equipment should
climb the antenna mast
• Only qualified professional personnel should install or dismantle
ODUs and masts
Note
• Do not tighten the ODU to its mounting brackets until the alignment
process of the antenna is complete.
• Ensure that there are no direct obstructions in front of the ODU or
interference from man-made obstacles.
Mounting the Lightning Protection Devices Chapter 3
RADWIN 2000 User Manual Release 2.5.40 3-8
To mount an external antenna:
1. To mount an external antenna, ensure that the antenna is properly grounded and
then mount the antenna onto the pole. Refer to Chapter 17 for detailed antenna
mounting instructions.
2. Follow the mounting instructions supplied with the antenna.
Mounting the Lightning Protection Devices
The use of lightning protection is dependent on regulatory and end user requirements. The
RADWIN 2000 ODU is designed with surge limiting circuits to minimize the risk of damage
due to lightning strikes. RADWIN recommends the use of additional surge arrestor devices to
protect the equipment from nearby lightning strikes.
Refer to Chapter 18 for detailed installation instructions of lightning protection devices.

Connecting power to the IDU Chapter 3
RADWIN 2000 User Manual Release 2.5.40 3-11
To mount an IDU-C:
1. Attach the rack mounting brackets (K) to the IDU.
2. Bolt the IDU into an empty slot in the rack, ensuring that it sits securely.
3. Ground the IDU to the rack using grounding lug I. The IDU should be left perma-
nently grounded.
Connecting power to the IDU
The IDU-C has redundant power connection circuits (items G and H in Figure 3-10 above).
An enlarged schematic of the power connectors is shown in below:
Figure 3-13: IDU-C Power connectors
The connectors are 3 pin in line female, with polarities (left to right) minus, ground, plus. To
avoid damage to the IDU, always use an AC/DC adapter supplied by RADWIN.
Ensure that the IDUs at both sites are powered up.
The IDU-E has a single three pin power connector, the same as used on the IDU-C.

Disconnection between ODU and IDU
Note
Instead of using the rack mounting brackets, the IDU may be rail mounted
using the four screw holes on each of its sides.
Connecting the ODU to the IDU Chapter 3
RADWIN 2000 User Manual Release 2.5.40 3-12
Connecting the ODU to the IDU
The ODU-IDU cable conducts all the user traffic between the IDU and the ODU, and also pro-
vides power to the ODU. The maximum length of the ODU-IDU cable is 100m (328ft) in
accordance with 10/100BaseT standards.
The ODU-IDU cable is supplied pre-assembled with RJ-45 connectors, at the length specified
when ordering, or as a cable drum with spare connectors. If the ODU-IDU cable was not
ordered, use an outdoor class, CAT-5e 24AWG shielded cable. See Appendix B for Wiring
Specifications.
To connect the ODU to the IDU, route the cable from the ODU to the IDU, secure the cable
along its path and connect the cable to the ODU RJ-45 connector on the IDU (see item B in
Figure 3-10 above).
Installing a Link using PoE Devices
The PoE device is a very simple unit having a power input connector and two Ethernet ports.
It is AC powered, and has a power LED.
To prepare a link using PoE devices:
1. To connect the ODU to the PoE device, route the cable from the ODU to the PoE
device, secure the cable along its path and connect the cable to the LAN-OUT RJ-45
connector on the PoE device.
2. Connect it to AC power.
3. Repeat steps 1 to 2 for the second link.
Connecting User Equipment
To connect user equipment to an IDU:
1. Connect user switch/router or any other compatible device to the IDU panel RJ-45
ports designated LAN. (For an IDU-C, see item C in Figure 3-10 above.)
2. Connect user E1/T1 traffic to the IDU panel RJ-45 ports designated TRUNKS. (For an
IDU-C, see labeled item L in Figure 3-10 above.)
3. IDU-C only: To use the SFP Port (labeled item D in Figure 3-10 above), insert an
SFP plug-in module into the port and connect the user switch/router or any other
compatible device to the SFP plug-in module.
Refer to Appendix B for connector pinouts.
To connect user equipment to a PoE device:
• Connect a user switch, router or any other compatible device to the PoE device RJ-45
port designated LAN-IN. Refer to Appendix B for connector pinouts.
Note
Do not connect two LAN ports to the same network, or flooding may occur.
Connecting and Aligning ODUs / Antennas Chapter 3
RADWIN 2000 User Manual Release 2.5.40 3-13
Connecting and Aligning ODUs / Antennas
You perform antenna alignment using the ODU's audible tone.
To speed up the installation time, alignment of a RADWIN 2000 system should be performed
by two teams simultaneously, at site A and at site B.
To align ODUs with integrated antennas or external bipolar antennas:
1. For external bipolar antennas: Using a coax cable with N-Type connectors, connect
the vertical polarization connector of the antenna to the ANT 1 connector of the
ODU.
2. For external bipolar antennas: Using a coax cable with N-Type connectors, connect
the horizontal polarization connector of the antenna to the ANT 2 connector of the
ODU.
3. Ensure that power is connected to the IDUs at both sites.
4. Ensure normal operation of the IDUs by the LED indications on the front panel.
Provided that site A detects the signal from site B, the ODU starts beeping 20 sec-
onds after power up, and continues beeping until the ODUs are aligned, and the
installation is complete.
In the following steps, “antenna” refers both to an external antenna and an inte-
grated antenna.
5. Direct the antenna of site B in the direction of site A. This is simplified if a previous
site survey has been completed and azimuths are known.
6. Make a horizontal sweep of 180 degrees with the site A antenna so that the strongest
signal from site B can be detected.
7. Slowly turn the site A antenna back towards the position of site B, listening to the
tone until the best signal is reached. See the following figure for audible signal varia-
tions.
Warning
When aligning the antennas, do not stand in front of a live antenna.
Connecting and Aligning ODUs / Antennas Chapter 3
RADWIN 2000 User Manual Release 2.5.40 3-14
Figure 3-14: Beep Sequence for antenna alignment
8. Secure the site A antenna to the pole/wall.
9. Repeat steps 4 to 8 for site B.
To align two external monopolar antennas:
1. Using a coax cable with N-Type connectors, connect one antenna to the ANT 1 con-
nector of the ODU.
2. Follow the steps 3 to 7 above to align the antenna connected to the ODU connector
ANT 1 on both sides of the link.
3. On both sides of the link, disconnect the antenna connected to the ODU connector
ANT 1. Connect the other antenna to connector ANT 1 and follow the steps 3 to 7
above to align the second antenna.
4. Secure the antennas to the pole/wall.
5. Restore one of the antennas to ANT 2 on both sides of the link.
Note
• Three beeps and a pause is 'best signal so far'
• Two beeps and a pause is 'signal quality increased'
• One beep and pause is 'no change in signal'
• Long beep and short pause is 'signal quality decreased'
• One beep and a long pause is 'no air link'
• Any other signal does not relate to antenna alignment
Note
The ODU buzzer only works on the radio connected to the ANT 1 connector
marked . You will therefore need to use ANT 1 to align both antennas in
turn. Upon completion of the alignment procedure, you may connect the
two antennas to ANT 1 and ANT 2 connectors.

lation wizard to complete the setup of the RADWIN Manager application.
If the installation program fails to start, browse to your CD/DVD drive, chose the
setup.exe program and run it.
Getting Started with the RADWIN Manager
If your links are within easy reach, you can configure them using the procedure described
below. If however, your links are to be geographically scattered, it may be convenient to pre-
load each ODU with its network address prior to physical installation. The procedure is quite
straight forward, and set out in Chapter 19.
To start the RADWIN Manager:
1. Connect the managing computer to one of the two LAN ports as shown in Figure 4-
1 below:
Note
Each ODU requires a static IP address, since part of the link definition is the
IP address pair of both ODUs. Network Managers should ensure that these
addresses are outside of the automatic allocation ranges used by their
network DHCP server.

RADWIN 2000 User Manual Release 2.5.40 4-3
Figure 4-1: LAN ports on the front panel of the IDU-C
If you are not using a direct connection as above, ensure that you have IDU to man-
aging computer connectivity (e.g. through a LAN).
2. Check that you have connectivity to the ODU. You can do this by opening up a com-
mand line session (Start|Run and then type, cmd). At the command prompt, type
ping 10.0.0.120
You should see something like this:
Figure 4-2: Pinging an uninstalled and unconfigured link
Any other response from ping means that the ODU is not responding. Check your
Ethernet connection and that both the IDU and ODU are switched on and then try
again. If you do not succeed, seek assistance from RADWIN Customer Support.
3. Dismiss the command line session.
4. Double-click the RADWIN Manager icon on the desktop, or click Start|Pro-

Log-on Errors and Cautions
Unsupported Device
Attempting to connect to an unsupported device on an otherwise valid IP address (for exam-
ple, a LAN printer) will result in the following error message:
Warning
• If you log on using Local Connection, but your physical connection
is not local (i.e. anything other than a direct connection between the
managing computer and the IDU), then any configuration you carry
out may affect other links in the network. Do not do this!
• Network log on (IP address to the ODU) is recommended.
• If you log on via an over-the-air IP address, you will receive a warn-
ing. If you reset the site to which you are connected to factory set-
tings, you can lock yourself out of the link.
Note
• If you log on using Local Connection through a PoE device, you will
need to connect it to the managing computer using a crossed Ether-
net cable.
• The default IP address for the ODU is 10.0.0.120. The subnet mask is
255.0.0.0.
• The actual IP address is defined during link configuration (see Site
Management: IP Address, VLAN and Protocol on page 8-7. See
also, Chapter 19).
Incorrect IP Address Chapter 4
RADWIN 2000 User Manual Release 2.5.40 4-7

Note
For what follows, it is assumed that you have set the IP addresses of both
ODUs. For the purposes of illustration, we will use the following IP
addresses:
Our managing computer has its NIC set to IP address 192.168.1.100. The
log-on ODU is set to IP address 192.168.1.101 and the over-the-air ODU is
set to 192.168.1.102. The Subnet Mask for both sites is 255.255.255.0 and
the Default Gateway is left unset. We will maintain this arrangement
throughout the remainder of this manual.
Other defaults are shown in Table 4-4.
First steps Chapter 4
RADWIN 2000 User Manual Release 2.5.40 4-10
A detailed field by field description of the contents of the RADWIN Manager main window
may be found in Chapter 6.
The procedure required to make the link functional has three phases:
1. Link Installation - which we will detail below.
Installation actually gets the link operational by setting the link parameters. It uses a fixed
channel at the lowest possible modulation, BPSK at 6.5Mbps and will work under the harsh
interference condition.
2. Link Configuration - described in Chapter 7.
Configuration provides much the same functionality as Installation, but for a running link.
A fallback to Installation mode is provided for situations which cannot be handled without
resetting the link, such as antenna realignment and IDU or ODU replacement.
The Link Installation and Configuration phases are both carried out with Wizards, which
“walk you through” the processes. The Wizards are visually quite similar and will be
described in detail below.
3. Site Configuration - described in Chapter 8.
Site specific configuration for each side of the link is available at any time - under a run-
ning link or under the restricted Installation mode.
Site Configuration consists of a set of panels, which may be invoked individually in any
order, as needed.
Note
The Dynamic Tx Ratio bar only appears for model RADWIN 2000 C
Note
During the installation procedure, the definition of all parameters is
automatically applied to both sides of the link.
Caution
• The ODUs as supplied by RADWIN are set up with a factory default
band. If for some reason the default band needs to be changed, it
should be done before link Installation. The procedure is set out in
Chapter 20.
• Use of an incorrect band may be in violation of local regulations.
Note
An installed and configured link can be returned to installation mode for re-
installation and configuration from last settings or from factory settings.
• Reversion to installation mode requires a complete break in the link
service
• Configuration mode may vary the service throughput and quality, but
without a service break

Installing the Link
Overview
The installation is carried out using the Installation wizard. Its operation is detailed in the fol-
lowing pages in a tutorial style.
For the purpose of explanation, we will set up a laboratory link with the following characteris-
tics:
•Channel selection: Automatic
•Antennas: Dual at both sites
•Services: Ethernet + 7xE1 on ports 1, 2, 3, 8, 10, 11, 14. It is unlikely that you would
use a non-contiguous set of ports - but this shows that if required, it can be done.
The Installation wizard has steps as shown in Table 5-1 below.

Step 3, Channel Settings
RADWIN 2000 systems have a feature called Automatic Channel Selection (ACS). In the event
of sync loss, ACS chooses the first available channel in a list of monitored channels nominated
in the Channel settings window of Figure 5-6 below. A channel switch takes place suffi-
ciently fast as to ensure no loss of service.

Figure 5-9: Transmission Power and Antenna Parameters
The choice of Tx Power, antenna gain and cable loss (between the radio and the antenna)
determines the EIRP and is affected by such considerations as radio limitations and regulatory
restrictions.
Before proceeding to antenna installation details, the following background information
should be considered:
About Single and Dual Antennas
Each RADWIN 2000 ODU is made of two radio transceivers (radios). The radios make use of
algorithms that utilize both MIMO and Diversity resulting in enhanced capacity, range and link
availability. The number of antennas (i.e. radios) used is determined by user configuration
and by automatic system decisions, explained below.
Dual Antennas at Both Sites
When using dual antennas at both sites (single bipolar antenna or two mo-unipolar antennas)
you can choose between MIMO Mode and Diversity Mode.
Installation Chapter 5
RADWIN 2000 User Manual Release 2.5.40 5-10
MIMO Mode
With MIMO the system doubles the link capacity. At the same time, it keeps the same rate
and modulation per radio as was used with single antenna, thus increasing capacity, range
and availability.
For example with a dual antenna RADWIN 2000 can transmit at modulation of 64QAM and
FEC of 5/6 and get an air rate of 130 Mbps, compared to 65 Mbps with single antenna.
To work in this mode, each antenna port must be connected to an antenna, the RSS level in
both receivers should be balanced and a minimal separation between the antennas must be
maintained. (For example, by using dual polarization antennas a cross polarization separation
is attained).
Upon selecting Antenna Type as Dual, RADWIN 2000 automatically selects MIMO mode and
doubles the air rates.
RADWIN Manager indicates a case of unbalanced RSS between the two antennas.
Diversity Mode
Diversity Mode uses two antennas to improve the quality and reliability of the link. Often,
there is not a clear line-of-sight (LOS) between transmitter and receiver. Instead the signal is
reflected along multiple paths before if-ally being received.
Each such “bounce” can introduce phase shifts, time delays, attenuations, and even distor-
tions that can destructively interfere with one another at the aperture of the receiving
antenna. Antenna diversity is especially effective at mitigating these multi-path situations.
This is because multiple antennas afford a receiver several recordings of the same signal.
Each antenna will be exposed to a different interference envy-remnant. Thus, if one antenna
is undergoing a deep fade, it is likely that another has a sufficient signal. Collectively such a
system can provide a or-bust link.
Antenna diversity requires antenna separation which is possible by using a dual-polarization
antenna or by two spatially separated antennas.
Use Diversity instead of MIMO in the following situations:
• When the system cannot operate in MIMO Mode
• When one of the receivers has high interference compared to the second receiver (i.e.
the system is “unbalanced”)
• When you achieve higher capacity in Diversity Mode than in MIMO Mode
• When high robustness is of importance and the capacity of Diversity Mode is sufficient
(up to 25 Mbps full duplex)
Single Antennas at Both Sites
By selecting a single antenna at both sites the ODUs operate with a single radio that is con-
nected to the ANT 1 connector. The second radio is automatically shut down.
Single at One Site, Dual Antennas at the Other
In this mode one of the sites uses the ODU with a single antenna while the other site uses the
ODU with a dual antenna.
The advantages in this mode in comparison to using a single antenna in both sites are dou-
bled total Tx Power and additional polarization and/or space diversity (depending on the
polarization of installed antennas).

The air rates used in this mode are same as when using single antennas in both sites.

Considerations for Changing Antenna Parameters
Let:
max Available Tx Power denote the maximum Tx Power practically available from an
ODU. It appears as Tx Power per Radio in Figure 5-10
below.
maxRegEIRP denote the maximum EIRP available by regulation. It will be determined by
three factors:
• per band/regulation
• per channel bandwidth
• antenna gain
It appears in Figure 5-10 as Max EIRP.
maxRegTxPower denote the maximum regulatory Tx Power for the equipment, also
having regard the above three points.
Then, the following relationship must be satisfied: ... (*)
These parameters are controlled as follows:
To set Tx Power and configure antennas:
1. Click the Configure buttons in turn to configure the antennas on both sides of the
link. Each one offers a dialog like this:

If inequality (*) above is violated, then the following warning window is displayed:
Figure 5-13: Tx Power Limits
The precise relationship between the items in inequality (*) and the window of
Figure 5-10 is as follows:
• Required Tx Power (per radio) will be adjusted down to the lesser of the value
entered and maxAvailableTxPower
• Tx Power (system) is maxAvailableTxPower + 3 (for 2 radios)
•Max EIRP is maxRegEIRP.
•EIRP is maxAvailableTx Power + Antenna Gain - Cable Loss
The table in Figure 5-13 only shows rates where the maximum Tx Power is the lim-
itation, rather than regulations. When you close the window of Figure 5-13, the
change you requested will not be honored, and you will need to try again.
Note
• The Max EIRP level will be automatically set according to the selected
band and regulation.
• The EIRP level is the sum of the System Tx Power and the Antenna
Gain minus the Cable Loss.

Limitations on the use of Asymmetric Allocation
For non collocated links, capacity allocation between uplink and downlink traffic is determined
automatically according to actual Ethernet traffic and air interface conditions. Your manual
allocation using this feature “cuts in” during congestion.
Asymmetric Allocation and Collocation
The use of Asymmetric Allocation is limited where the link is collocated. Possible scenarios are
shown in Table 5-4. In all cases where Asymmetric Allocation is available, it is static for all
traffic conditions.

Configuring the Link
Overview
This chapter describes the link configuration procedure, which is performed after the installa-
tion of both sides of the RADWIN 2000 link, as set out in Chapter 5.
Link configuration uses a Link Configuration wizard to redefine the configuration parameters
and fine-tune an operational link. Both sides of the link are configured simultaneously.
Link configuration allows you to configure link parameters, which do not lead to sync loss or
require a reset. Some may change service performance, in respect of which, warnings are dis-
played.
For ease of use, the Link Configuration wizard follows the same pattern as Link Installation.
You should therefore be familiar with the content of Chapter 5.
The following parameters are configured using the Link Configuration Wizard:
• System parameters
• Channel settings
• Transmission power and antenna settings
• Service parameters
The Configuration Wizard has seven steps as shown in Table 7-1 below.

Configuration
Since configuration functionality is included in the installation, we will briefly review the main
steps and for most part offer references to the corresponding installation step.
Step 1, Start the Wizard
In the tool bar of the RADWIN Manager main window, click the Link Configuration button.
The Link Configuration button is only accessible on a fully installed link as set out in Chapter
5.
The Configuration Wizard opens:
Figure 7-1: Link Configuration Wizard
Click Next to proceed with the configuration procedure.
Step 2, System Parameters
The System dialog box opens:
Configuration Chapter 7
RADWIN 2000 User Manual Release 2.5.40 7-4
Figure 7-2: Configuration Wizard, System dialog box
The System attributes may be edited and the Link Password may be changed exactly as in the
corresponding Link Installation step on page 5-5.
Click Next to continue.
Step 3, Channel Settings
Configuring the Channel Settings follows the same pattern as the Installation procedure:
Configuration Chapter 7
RADWIN 2000 User Manual Release 2.5.40 7-5
Figure 7-3: Channel Settings dialog box - Automatic Channel Selection
Notice that the operating channel is grayed out. If you use the Reselect Channel button, to
change it, you will be asked for confirmation:
If you accept, then the system will search for the best operating channel:
Configuration Chapter 7
RADWIN 2000 User Manual Release 2.5.40 7-6
Figure 7-4: Searching for the best operating channel
The link will return to the status of Figure 7-3 above with a possible change to the operating
channel.
If you work without automatic channel selection, the Channel Settings window looks like this:
Figure 7-5: Channel Settings without automatic channel selection
If you click the Operating Channel drop-down list, the following window appears:
Configuration Chapter 7
RADWIN 2000 User Manual Release 2.5.40 7-7
Figure 7-6: Channel frequency options
Selecting one of the frequencies presented returns you to the status of Figure 7-5 with the
appropriate change. If you choose Other..., the following window opens:
Figure 7-7: Choosing an “Other” Operating Channel frequency
The right hand drop-down list (showing the current Operating Channel) allows you to fine-
tune the frequency in increments of ±5MHz within a range of the operating band, which in
this example is 5.740 - 5.835 GHz.
Configuration Chapter 7
RADWIN 2000 User Manual Release 2.5.40 7-8
The Channel Bandwidth may also be changed. The available choices are 10, 20 and 40MHz
depending on regulation (see Appendix A).
When you have completed making your choice, click Next to continue.
Step 4, Tx Power and Antenna Settings
The Tx Power and Antenna Settings window is similar to that for Installation:
Figure 7-8: Transmission Power and Antenna Parameters
As in Installation mode, you need to consider three items:
• Number of antennas at each Link site (1 or 2)
• Tx Power setting for each one
• MIMO or Diversity mode
Changing Number of Antennas and Tx Power
TX Power, Antenna Gain and Cable Loss
If you chose to configure either antenna, you are presented with the following window:
Configuration Chapter 7
RADWIN 2000 User Manual Release 2.5.40 7-9
Figure 7-9: Antenna configuration dialog with opened type selection
(Recall that we are using an unrealistically low Tx power here because our link in a labora-
tory.)
So far, the procedure duplicates the corresponding Installation process. If you choose a differ-
ent antenna type and click OK, you will receive the following cautionary message:
You may also change the Required Tx Power, Antenna Gain and Cable Loss. The procedure is
the same as that set out in the Installation procedure on page 5-13.
Switching Between Single and Dual Antennas
Single/Dual Antenna mode selection works precisely the same way as shown on page 5-20.
If you use this option you will receive a warning similar to this:
Caution
In this context, entering Installation mode causes a service break until it is
restored by running the Installation wizard.
If you are uncertain, do not do this without expert technical assistance.
Configuration Chapter 7
RADWIN 2000 User Manual Release 2.5.40 7-10
Switching Between MIMO and Diversity Modes
A similarly worded warning applies to a s switch from Diversity to MIMO mode. The consider-
ations are otherwise no different from those set out in the corresponding Installation step.
When you have completed making your choice, proceed to the Services window.
Step 5, Hub Site Synchronization Settings
Figure 7-10: HSS Settings
The Synchronization Status dialog box displays the current status of each side of the link. See
Chapter 10 for instructions about installing and configuring collocated links. If you do not
require HSS, click Next.
Step 6, Services
Here is the services dialog:
Configuration Chapter 7
RADWIN 2000 User Manual Release 2.5.40 7-11
Figure 7-11: Services and Rates dialog
To choose Services, see the corresponding Installation procedure in Chapter 5.
If you are using a link that -
• is non-collocated
• is Ethernet-only
• uses model RADWIN 2000 C ODUs
then you may use Asymmetric Allocation. You may change the capacity allocation here the
same way as during installation. In place of the IDU box in Figure 7-11, you will see the
Asymmetric Allocation slider:
The procedures for setting the Jitter Buffer and Hot Standby parameters are also the same as
the corresponding procedures in Chapter 5.
Click Next to continue.
Step 7, TDM Clock Configuration
The following dialog is displayed:

RADWIN 2000 User Manual Release 2.5.40 8-5
Figure 8-4: HSS Status
Site Management: IP Address, VLAN and Protocol
Configuring the ODU Address
Each site must be configured separately. For an over-the air configuration, first configure site
B then site A so as to avoid lockout. See Chapter 19 for detailed instructions about the best
way to do this on-site.
See Chapter 14 for further details about VLAN Functionality for RADWIN 2000.
To define the Management Addresses:
1. Choose a site to configure.
The Configuration dialog box opens:
Configuring VLAN Settings Chapter 8
RADWIN 2000 User Manual Release 2.5.40 8-6
Figure 8-5: Management Addresses - Site Configuration dialog box
5. Choose Management.
6. Enter the IP address of the ODU in the IP Address field.
7. Enter the Subnet Mask.
8. Enter the Default Gateway.
9. Enter the Trap Destination. This could be the IP address of the managing computer.
The events log will be stored at this address.
10. Click Apply to save the changes.
Configuring VLAN Settings
VLAN Management enables separation of user traffic from management traffic whenever such
separation is required. It is recommended that both sides of the link be configured with differ-
ent VLAN IDs for management traffic. (This reduces your chances of accidentally locking
yourself out of the link.)
To enable VLAN management:
1. Click Configuration from the main menu.
Note
If performing configuration from the RADWIN Manager, the IP address is
that entered from the Login window.
Caution
VLAN IDs are used by RADWIN products in three separate contexts:
Management VLAN, Traffic VLAN and Ethernet Ring. It is recommended that
you use different VLAN IDs for each context.
Lost or forgotten VLAN ID Chapter 8
RADWIN 2000 User Manual Release 2.5.40 8-7
2. Choose a site to configure. If you are configuring both sites, choose site B first to
avoid locking yourself out.
3. Choose Management.
4. Open the VLAN tab.
5. Check the Enabled box.
6. Enter a VLAN ID. Its value should be between 1 and 4094.
After entering the VLAN ID, only packets with the specified VLAN ID are processed
for management purposes by the ODU. This includes all the protocols supported by
the ODU (ICMP, SNMP, TELNET and NTP). The VLAN priority is used for the traffic
sent from the ODU to the managing computer. Using VLAN for management traffic
affects all types of management connections (local, network and over the air).
7. Enter a Priority number between 0 and 7.
8. Change the VLAN ID and Priority of the managing computer NIC to be the same as
those of steps 6 and 7 respectively.
9. Click Apply or OK.
Figure 8-6: Configuring management traffic VLAN Settings
Lost or forgotten VLAN ID
If the VLAN ID is forgotten or there is no VLAN traffic connected to the ODU, then reset the
relevant ODU.
Caution
Changing this parameter causes the RADWIN Manager to immediately
disconnect. To avoid inconvenience, you should verify the change by
setting the VLAN only to one ODU, and only after verifying proper
management operation, change the other ODU VLAN setting.
Enable / Disable Telnet Access Chapter 8
RADWIN 2000 User Manual Release 2.5.40 8-8
During the first two minutes of connection, the ODU uses management packets both with and
without VLAN. You may use this period to reconfigure the VLAN ID and priority.
Enable / Disable Telnet Access
For a link managed in a network, direct access to an ODU using Telnet is considered to be a
security breach. Telnet access may be enabled or disabled by clicking the Protocol tab and
enabling/disabling Telnet access using the Telnet check-box:

Security Features Chapter 8
RADWIN 2000 User Manual Release 2.5.40 8-9
Security Features
The Security dialog enables you to change the Link Password and the SNMP Community
strings and use the Link Lock feature:
Figure 8-9: Available security features
Changing the Link Password
This item is only available when the link is down. Otherwise, it works the same way as the
corresponding item on page 5-8.
RADWIN Manager Community Strings
The ODU communicates with the RADWIN Manager using SNMPv1 protocol. The protocol
defines three types of communities:
•Read-Only for retrieving information from the ODU
•Read-Write to configure and control the ODU
•Trap used by the ODU to issue traps.
The Community string must be entered at log on. The user must know the password and the
correct Community string to gain access to the system. A user may have read-only privileges.
It is not possible to manage the ODU if the read-write or the read Community values are for-
gotten. A new Community value may be obtained from RADWIN Customer Support for the
purpose of setting new Community. You must also have available the serial number or the
MAC address of the ODU.
The read-write Community strings and read-only Community strings have a minimum of five
alphanumeric characters. (bru1 and bru4097 are not permitted). Changing the trap Com-
munity is optional and is done by clicking the check box.
RADWIN Manager Community Strings Chapter 8
RADWIN 2000 User Manual Release 2.5.40 8-10
Editing Community Strings
The Community change dialog box is available from the Configuration | Security tab. Both
read-write and read-only communities must be defined.
On logging on for the first time, use the following as the current Community:
• For Read-Write Community, use
netman
.
• For Read-Only Community, use
public
.
• For Trap Community, use
public
To change a Community string:
1. From the Configuration dialog box, choose the Security tab.
2. Type the current read-write Community (default is
netman
).
3. Choose the communities to be changed by clicking the check box.
4. Type the new Community string and re-type to confirm. A community string must
contain at least five and no more than 32 characters excluding SPACE, TAB, and any
of “>#@|*?;."
5. Click OK to save.
Figure 8-10: Changing the Community String
Forgotten Community string
If the read-write Community string is unknown, an alternative Community key can be used.
The alternative Community key is unique per ODU and can be used only to change the Com-
munity strings. The alternative Community key is supplied with the product, and should be
kept in a safe place.
If both the read-write Community and the alternative Community key are unavailable, then
an alternative Community key can be obtained from RADWIN Customer Support using the
ODU serial number or MAC address. The serial number is located on the product label. The
serial number and the MAC address are displayed in the Site Configuration inventory tab.
When you have the alternative Community key, click the Forgot Community button and
enter the Alternative Community key (Figure 8-11). Then change the read-write Community
string.
Link Lock Security Feature Chapter 8
RADWIN 2000 User Manual Release 2.5.40 8-11
Figure 8-11: Alternative Community Dialog box
Link Lock Security Feature
Link Lock is a part of RADWIN’s security concept intended to meet a form of abuse
encountered in the field. It is designed to prevent the situation where a remote ODU
can be stolen and used as a “pirate” link to steal services or information. The Link
Lock feature actually locks the local ODU to be synchronized ONLY to specific remote
ODU. It is a
site oriented
feature.
The lock can only be set from a live link. It is based on MAC authentication and is site
oriented and activated on a per ODU basis. For example, if you lock the Site B ODU to
the Site A ODU, you must still lock the Site A ODU to the Site B ODU to ensure
complete two way locking.
Link Lock can only be removed when the link is unsynchronized. In such a case, an
alarm is raised by the RADWIN Manager.
To enable Link Lock:
1. Click Site A on the main tool bar.
2. Choose the Security tab. The following window is displayed:
Link Lock Security Feature Chapter 8
RADWIN 2000 User Manual Release 2.5.40 8-12
3. Click the Link Lock check-box and then OK. You are asked to confirm the
lock:
4. Click the Yes button and you are returned to the main window of the
RADWIN Manager.
Observe that a link icon is now displayed in the status bar on the bottom right of the
RADWIN Manager window.
The link to the remote unit is now locked. If you repeat steps 1 and 2 above, the
Security screen will look like this:
Setting the Date and Time Chapter 8
RADWIN 2000 User Manual Release 2.5.40 8-13
The Link Lock check-box is now unavailable.
5. If required, repeat the procedure for Site B.
Setting the Date and Time
The ODU maintains a date and time. The date and time should be synchronized with any Net-
work Time Protocol (NTP) version 3 compatible server.
During power-up the ODU attempts to configure the initial date and time using an NTP Server.
If the server IP address is not configured or is not reachable, a default time is set.
When configuring the NTP Server IP address, you should also configure the offset from the
Universal Coordinated Time (UTC). If there is no server available, you can either set the date
and time, or you can set it to use the date and time from the managing computer. Note that
manual setting is not recommended since it will be overridden by a reset, power up, or syn-
chronization with an NTP Server.
Note
To revert the Link Lock status to unlocked, power down each ODU
in turn. Use the above procedure to uncheck the Link Lock status
box for the live ODU.
A simple ODU reset at either end will restore the link to its previous
locked or unlocked state.
Note
The NTP uses UDP port 123. If a firewall is configured between the ODU
and the NTP Server this port must be opened.
It can take up to 8 minutes for the NTP to synchronize the ODU date and
time.
Setting the Date and Time Chapter 8
RADWIN 2000 User Manual Release 2.5.40 8-14
To set the date and time:
1. Determine the IP address of the NTP server to be used.
2. Test it for connectivity using the command (Windows XP), for example:
w32tm /stripchart /computer:216.218.192.202
You should get a continuous response of times, each a few seconds apart.
3. Choose a site to configure.
The Configuration dialog box opens.
4. Choose Date & Time:
Figure 8-12: Date and Time Configuration
5. If entering an IP address for the NTP Server, click Clear, and then enter the new
address.
6. Set your site Offset value in minutes ahead or behind GMT1.
7. To manually set the date and time, click Change and edit the new values.

Ethernet Properties
Configuring the Bridge
Bridge configuration is required in various network topologies, such as protection (Ethernet
1+1) and ring applications. The bridge configuration parameters are located under the
Advanced tab of the Site Configuration dialog box:
Configuring the Bridge Chapter 8
RADWIN 2000 User Manual Release 2.5.40 8-16
Figure 8-15: Bridge, VLAN and MIR Configuration
ODU Mode
This parameter controls the ODU mode with two optional values:
• Hub Mode - in Hub mode the ODU transparently forwards all packets over the wireless
link.
• Bridge Mode - In Bridge mode the ODU performs both learning and aging, forwarding
only relevant packets over the wireless link. The aging time of the ODU is fixed at 300
seconds.
IDU Aging time
This parameter controls the IDU aging time.
The aging time parameter controls the time after which each MAC address is dropped from
the MAC address learning table.
The default value is 300 seconds.
Note
RADWIN 2000 C-Series ODU products work in Hub mode only. The bridge
capability is built in to the IDU-C (it is not configurable). If an IDU-C is
connected to an RADWIN 2000 C ODU, then the IDU-C performs the
bridging.
Note
Changing these modes requires system reset.
Note
• Any change to these parameters is effective immediately.
• Each side of the link can be configured separately, with different
aging times.
Configuring Ethernet Ports Mode Chapter 8
RADWIN 2000 User Manual Release 2.5.40 8-17
The following table shows the appropriate configuration for several common scenarios. Both
link sites must be configured with the same parameter:
Configuring Ethernet Ports Mode
The ODU Ethernet port is configured to auto-detect by default and may not be changed.
The ODU Ethernet port mode is configurable for line speed (10/100BaseT) and duplex mode
(half or full duplex).
An Auto Detect feature is provided, whereby the line speed and duplex mode are detected
automatically using auto-negotiation. Use manual configuration when attached external
equipment does not support auto-negotiation. The default setting is Auto Detect.
To configure the Ethernet Mode:
1. From the Configuration menu, choose the site to configure.
The Site Configuration dialog box opens.
2. Click Advanced | Ethernet.
3. In the Ethernet Ports Configuration pane, use the drop-down menu to choose the
configuration.
4. Click Apply to save the changes.

Caution
You should not reconfigure the port that is used for the managing computer
connection, since a wrong configuration can cause a management
disconnection or Ethernet services interruption.
Note
It is possible to close the Ethernet service by disconnecting the Ethernet
port.
If you close the port, you may subsequently be unable to access the
device. If this should occur, a workaround is as follows:
• Connect the system from the remote site
• Connect via other Ethernet port (of the IDU)
• Power down the equipment and connect immediately after power
up (the fastest way is to enter install mode)
VLAN Tagging for Ethernet Service: Configuration Chapter 8
RADWIN 2000 User Manual Release 2.5.40 8-18

Caution
VLAN IDs are used by RADWIN products in three separate contexts:
Management VLAN, Traffic VLAN and Ethernet Ring. It is recommended that
you use different VLAN IDs for each context.
Note
If you are using a new style IDU-E, the SFP row will not appear.
Setting the Maximum Information Rate (MIR) Chapter 8
RADWIN 2000 User Manual Release 2.5.40 8-19
The details of setting up VLAN tagging require advanced network management skills beyond
the scope of this manual. Further information for the Network Manager is provided in Chap-
ter 14.
Setting the Maximum Information Rate (MIR)
What is the MIR
The maximum Ethernet throughput of the link (MIR) can be limited. The default setting is
Best Effort
(see Figure 8-15 above), where the highest information rate available for the link
conditions and settings is used.
What is it for
The MIR setting limits the throughput for Ethernet service. It does not affect the capacity of
TDM services.
If the Link Budget Calculator or air conditions limit the capacity to X Mbps, and suppose that
you use Y (< X) Mbps for TDM services, then you are left with X - Y=Z Mbps for Ethernet.
Suppose for example, that Z = 20 Mbps.
As a Service Provider, you can decide to sell a package based on 10Mbps and charge $P1 for
it, or 15 Mbps for $P2 > $P1.
The MIR setting allows you do this.
The default value is “best effort” which will give Z above.
To limit the Ethernet information rate:
1. From the Configuration menu, choose the site to reconfigure.
2. Click Advanced | Ethernet
The Configuration dialog box opens.
Note
The minimum value is 256 Mbps.
The maximum value will be the minimum between Z above and -
• 10 Mbps for RADWIN 2000 PDH
• 50 Mbps for RADWIN 2000 L
• 100 Mbps for RADWIN 2000 C
The MIR setting is independent per direction.

IDU Detection
An ODU always tries to detect the IDU to which it is connected. IDU Detection is effected by
an IDU responding to special ODU packets.
If a PoE device is in use, the detection packets spread to the containing network and may
cause flooding. In such a case, the IDU Detection feature, (Figure 8-21), should be dis-
abled.

Backup/Restore of ODU Software Files
Backup ODU Software to a File
RADWIN Manager allows you to backup the ODU software of both units of a link to the man-
aging computer as binary files. Each site is backed up in a separate file. Backup files are
matched to the MAC address of the site ODU. The default backup file name is constructed
from the ODU IP address and the date as in the following example:
Backup of Site A as used in our examples:
192.168.1.101_1.12.2009.backup
If you perform more than one backup on a given date you will need to change the file name
to something like this:
192.168.1.101_1.12.2009_00.backup
192.168.1.101_1.12.2009_01.backup
...
To backup the ODU software a file:
1. Choose a site to back up. The Site Configuration dialog box opens.
2. Click Backup.
3. In the Save As dialog box, indicate in which folder and under what name configura-
tion file is to be saved, and click Save.
Restoring ODU Software or Configuration
Backup files can be uploaded from the managing computer. You may choose a full software
restore or configuration-only restore.
To restore from a backup file:
1. Choose a site to restore (from a previous backup).
The Site Configuration dialog box opens.
2. Click Restore. You are offered the choice of a Full or Configuration Restore as
shown:
3. Click the required Restore type. You are then offered a standard Open File dialog

Events, Alarms and Traps Chapter 9
RADWIN 2000 User Manual Release 2.5.40 9-13
Figure 9-15: Threshold configuration dialog box
RSL Thresholds
Two RSL Thresholds can be defined. They are used as an indicator of problems in the radio
channel. You can check the RSS from the Link Budget Calculator results during installation.
Values of -5dB and -8dB from the current RSS are typical.
TSL Threshold
A counter is maintained, of the number of second intervals during which Tx power exceeds
this threshold.
BBER Threshold
The Background Block Error Ratio is measured as a percentage. The threshold can be set
from 0.1% up to 50%.
For links with Ethernet only service, 8% threshold is recommended. If there are no problems
during the interval, then for that threshold, the recommended BBER value should be 0. Since
the system provides a lossless Ethernet service, there is throughput degradation in case of
interference. The degradation is proportional to the BBER.
Ethernet Thresholds - Capacity
This is used as a basis for checking adherence to a Service Level Agreement. It is the number
of seconds count that the link capacity falls bellow the threshold.
Ethernet Thresholds - Traffic
The number of seconds count that received traffic exceeded this threshold. It can be used to
measure traffic peaks.
Events, Alarms and Traps

cant if you are using an SNMP based network management system such as RADWIN NMS.
Remote Power Fail Indication
Remote power fail indication indicates to one side that the other side has suffered a power
failure. The failed site sends a final trap indication about the power loss just before powering
off.
A “Dying-Gasp” circuit identifies the power failure at a minimum interval of 20 milliseconds
before the ODU or IDU powers off. During that interval a message notifying the power failure
is sent to opposite site. External alarm output number 4 indicates power failure at the oppo-
site site.

Replacing an ODU Chapter 9
RADWIN 2000 User Manual Release 2.5.40 9-20
Use the following table to troubleshoot faults in the system:.
Replacing an ODU
Prior to any action ensure that both ODUs have the same software version. You can see this
on the inventory panels for each site.
For Site A, click Site A | Inventory and note the ODU software version. Repeat this for Site
B using Site B | Inventory.
If either ODU has an old software version, perform a software upgrade. It is important to con-
figure the new ODU identically to the old ODU to avoid configuration mismatches, which will
disrupt the link.
An ODU may be reconfigured in several ways.
• Use the backup configuration
If a backup of the configuration is available, restore that configuration using Site A|
Restore. Recall that backup files are linked to a MAC address. This won’t work for
an identical replacement ODU.
• Manual configuration
The new ODU can be configured manually according to the link configuration.
Remember to use the same settings for Link ID, channels, link password, IP
addresses, and names.

Hub Site Synchronization
What is Hub Site Synchronization?
When several units are collocated at a common hub site, interference may occur from one
unit to another. RADWIN ODU units support the collocation of more than two units at a cen-
tral site. Like any other RF deployment, the wireless operation is highly dependent on factors
such as available frequencies, the physical spacing between radios, other interfering radios,
and whether WinLink 1000 or RADWIN 2000 units are installed.
The RADWIN Hub Site Synchronization (HSS) method uses a cable connected from the mas-
ter ODU to all collocated ODUs; this cable carries pulses sent to each ODU, which synchronize
their transmission with each other. The pulse synchronization ensures that transmission
occurs at the same time for all collocated units. This also results in all of the hub site units
receiving data at the same time, eliminating the possibility of interference that could result if
some units transmit while other units at the same location receive.
Figure 10-1 illustrates interference caused by non-synchronized collocated units.
Note
HSS does not eliminate the need for careful RF planning to ensure the
design will work as planned. See Chapter 2 of the User Manual (both
WinLink 1000 and RADWIN 2000) for information on installation site survey.
For WinLink 1000 units, Hub Site Synchronization support depends on the
product model.
What is Hub Site Synchronization? Chapter 10
RADWIN 2000 User Manual Release 2.5.40 10-2
Figure 10-1: Interference caused by collocated units
Adding HSS removes interference as shown in the next two figures:
Figure 10-2: Collocated units using Hub Site Synchronization (1)
Figure 10-3: Collocated units using Hub Site Synchronization (2)
The units are connected to each other with HSS cables and HSS Distribution Units.
One of the radios in the site is defined as HSS Master and generates synchronization pulses.
The other collocated radios in the site - the HSS Clients, are connected to the HSS Master and
synchronize their transmission to the pulses. An HSS Client can be configured to work in one
of two modes:
Hardware Installation Chapter 10
RADWIN 2000 User Manual Release 2.5.40 10-3
•HSS Client-Continue Transmission (HSC-CT): If the unit loses synchronization
with the HSS Master, the link remains active. However, without synchronization pulses,
it is possible that this unit will cause interference.
•HSS Client-Disable Transmission (HSC-DT): If the unit loses synchronization with
the HSS Master, the link is dropped until the synchronization pulses resume. This set-
ting prevents the unit from causing interference.
The remote ODUs that are not located at the hub site, are called Independent Units.
Hardware Installation
Connecting an HSS Unit
A single HSS unit supports up to ten collocated ODUs. In addition to each unit being con-
nected to its IDU or PoE device, the collocated unit has an additional cable that is connected
to the HSS Unit. The HSS Unit is a compact, weatherproof (IP67) connector box that is
installed on the same mast as the ODUs. All collocated units connect to this box using CAT-5e
cable. Cables in prepared lengths are available for purchase.
The HSS unit is supplied with ten protective covers; any port not in use must be closed with a
protective cover.
Figure 10-4: HSS Interconnection Unit
To connect an ODU to an HSS unit:
1. Unscrew the protective cover from the port marked SYNC 1.
2. Connect the RJ-45 connector from one end of the prepared CAT-5e cable to SYNC 1.
3. Connect the other end of the CAT-5e cable to the ODU connector labeled SYNC.
Note
WinLink 1000 radios used as independent units do not require HSS
hardware.
Note
• For a single HSS unit, ensure that the collocated units are connected
in sequence from SYNC 1. If an ODU is removed from the hub site,
then all remaining ODUs must be reconnected to maintain the con-
nectivity.
• You may cascade (daisy-chain) two or more HSS Units with an HSS
cable. The method is described in detail below.
Using a Single HSS Unit Chapter 10
RADWIN 2000 User Manual Release 2.5.40 10-4
4. Tighten the protective seal that is on the prepared cable over the RJ-45 connector.
5. Repeat for all ODUs that are to be collocated at the hub site. The next ODU to be
connected is inserted in SYNC 1, SYNC 2, followed by SYNC 3 and so on.
Using a Single HSS Unit
Figure 10-5: HSS Wiring schematic
The wiring, as shown in Figure 10-5 is self explanatory. The Sync signal path is less self evi-
dent. If we set ODU 1 (on SYNC 1) to HSS Master, then the Sync signal path is as shown in
Figure 10-6. The signal travels from ODU 1 to SYNC 1, from SYNC 1 to SYNC 2, from SYNC
2 to ODU 2 and back again. The back and forth paths repeat for the second to fourth ODU,
from left to right. The signal exits the HSS unit at SYNC 5 and terminates in ODU 5.
The choice of the ODU on SYNC 1 as HSS master is not mandatory, but is good practice. If for
example we were to use ODU 3 as HSS master, the Sync signal path would be ODU 3 to SYNC
3, then left and right to SYNC 2 and SYNC 4. It would then propagate to ODUs 2 and 4, termi-
nating at both ODUs 1 and 5.

Using More than One HSS Unit Chapter 10
RADWIN 2000 User Manual Release 2.5.40 10-5
Using More than One HSS Unit
In a large collocation site, several HSS units may be cascaded (daisy-chained) subject to the
following conditions:
Condition 1: Cabling Sequence
1. Up to nine ODUs may be connected to the first HSS unit using HSS ports SYNC 1, SYNC 2,
SYNC 3,... up to SYNC 9 in order without leaving empty ports.
2. The next available SYNC port of the first HSS unit should be connected to SYNC 10
of the second HSS unit as shown in Figure 10-7. In the illustration, the next
available port on the first HSS unit is SYNC 6.
3. The second HSS unit may be filled out with up to nine more ODUs in reverse
order. That is, connect SYNC 9, SYNC 8, SYNC 7... as shown in Figure 10-7.
Figure 10-7: Cascading two HSS units
4. To add a a further HSS unit: Connect the next available SYNC port from the second
HSS unit in descending order (SYNC 5 in Figure 10-7) to SYNC 1 of the third
HSS unit.
5. ODUs are connected to the third HSS unit from SYNC 2 as shown in Figure 10-8,
in ascending order:
HSS Error Notification Chapter 10
RADWIN 2000 User Manual Release 2.5.40 10-6
Figure 10-8: Cascading three HSS units
6. If further ODUs are required, observe the convention that additional even
numbered units are populated in descending order from SYNC 9 and odd
numbered HSS units are populated in ascending order from SYNC 2.
Condition 2: Total HSS Cable Length
The total path of the HSS sync pulse must not exceed 300m. This applies no matter how
many HSS units are used. To illustrate the method for calculating the sync pulse path length
we show three examples. For our purpose, let:
Lmn denote the length of the ODU-HSS unit cable at SYNC n on HSS unit m
Hm be the length of the cable joining HSS unit m to HSS unit m+1

HSS Error Notification
In the event of an HSS installation fault, the ODU will sound a beep pattern according to the
following chart, also printed on the ODU product label:

Radio Frame Pattern (RFP)
A Radio Frame Pattern (RFP) is the cycle duration of transmit and receive of the air-frame.
Without HSS
When selecting TDM or Ethernet services, the system automatically and transparently
chooses the optimal RFP. When TDM and Ethernet services are configured, the RFP is opti-
mized for TDM.
RFP and HSS
When HSS is used, the RFP for the collocated radios must be selected manually.
Both WinLink 1000 and RADWIN 2000 use the Time Division Duplex (TDD) mechanism.
Under HSS, TDD enables synchronization of transmission for the collocated units as shown in
Figure 10-10:

RADWIN 2000 User Manual Release 2.5.40 10-9
• If you mix RADWIN 2000 and WinLink 1000 units in a collocated site, you must use
RFP B or E
• Selection of the RFP influences the capacity, latency and TDM quality
• RFP influences capacity and latency. Jitter buffer configuration can be used to set the
TDM quality (see the User Manual, Chapter 5, TDM Services selection)
• Using the Link Budget Calculator, you can see the affect of the RFP on the Ethernet
throughput.
RFP: RADWIN 2000 Considerations
• The performance of RADWIN 2000 radios that operate with RFPs B or E can be seen
in the Link Budget Calculator.
• For RADWIN 2000 C series: If the HSS Master works in asymmetric Tx/Rx ratio, then
all other collocated RADWIN 2000 units must operate in the same Tx/Rx ratio. In this
case the ratio will be fixed and not automatic-adaptive.
• Installation/Configuration considerations: If you are using RADWIN 2000 C master
and RADWIN 2000 clients, the Services and Rates dialog will look like this:
Figure 10-11: Services and Rates - RADWIN 2000 C master, RADWIN 2000 clients
• The circled areas should not be used. Using those areas, you may loose the collocated
link with the longest distance between sites. If you do move the slider into a circled
area, you will receive a popup warning:

RADWIN 2000 User Manual Release 2.5.40 10-10
Figure 10-12: Services and Rates - RADWIN 2000 C master, RADWIN 2000 clients - Extreme
asymmetric allocation
By restricting one direction into the restricted area, the more distant sites may not
even be able to sustain the link much less send or receive data.
• Asymmetric Allocation and Collocation: If the link is collocated, the use of Asymmetric
Allocation is limited.
The effective available range for Asymmetric Allocation (between the two circled tick
in Figure 10-11) is primarily determined by three factors:
• The RFP in use (B or E)
• Channel Bandwidth
•Link distance
The first two parameters are entered during Link
Installation/Configuration.
• Possible scenarios are shown in Table 10-4.Whenever Asymmetric Allocation is avail-
able, it is static for all traffic conditions.
RFP: WinLink 1000 Considerations Chapter 10
RADWIN 2000 User Manual Release 2.5.40 10-11
RFP: WinLink 1000 Considerations
• When WinLink 1000 radios are collocated with RADWIN 2000 radios using HSS, all
radios must use RFP B or E.
• The performance of WinLink 1000 radios that operate with these RFPs can be seen in
the Link Budget Calculator.
• The choice of the unit to be the HSS master is a matter of convenience. There is no
technical reason to prefer a WinLink 1000 over a RADWIN 2000 as HSS master or vice
versa. It is however, recommended that you use the RADWIN 2000 as master, since it
will enforce the correct RFP on the other collocated units.
The following list summarizes the effect of using RFP B or E on WinLink 1000 radios. These
effects should be taken into consideration when planning new installations:
• Channel bandwidth 5 MHz is available under RFP E but is only supported for WinLink
Access products
• For products supporting a maximum throughput of 18.1 Mbps, the maximum Ethernet
throughput is 14.5 Mbps at 20 MHz channel bandwidth and 9.3 Mbps at 10 MHz chan-
nel bandwidth
• For products supporting maximum throughput of 22.5 Mbps, the maximum Ethernet
throughput is 21.4 Mbps at the 20 MHz channel and 9.3 Mbps at 10 MHz channel
bandwidth

Using the RADWIN GSU
What is it for
The GPS-based synchronization unit (GSU) is designed to handle inter-site interferences
under large-scale deployment scenarios.
The GSU is an outdoor unit consisting of a standard WinLink 1000 enclosure, a GPS antenna
and a PoE device.
The GSU is connected to the HSS Unit using a standard HSS cable. It synchronizes the trans-
mission timing of multiple Hub-Sites to the same clock source thus eliminating mutual inter-
ference.
GSU Functionality
The GSU receives a synchronization signal from the GPS once per second. It distributes a
RADWIN proprietary synchronization signal to all other ODU units using the RS422 protocol
and the standard HSS mechanism, where the GSU acts as an HSM unit.
When the GSU doesn’t receive a synchronization signal from the GPS for 30 seconds, it moves
automatically to Self-Generation mode and acts as a regular HSM unit, until the GPS recovers.
Typical GSU Scenarios
Independent Distributed Sites
In the scenario of Figure 11-1, we have multiple independent collocated sites, which may
interfere with each other. To meet this situation, we coordinate all of them using the GSU as
shown.
The GSU functions like “wide area HSS unit”, ensuring that all participating radios at the loca-
tions marked GSU each transmit and receive at the same time.
Multiple Distributed Sites with Communication Chapter 11
RADWIN 2000 User Manual Release 2.5.40 11-2
pendent dis tributed sites
Figure 11-1: GSU Scenario - Independent distributed sites
Multiple Distributed Sites with Communication
What happens if, in Figure 11-1, the GSU towers themselves have radios communicating as
shown in Figure 11-2?
Consider GSU 1 and GSU 2: Both collocated towers transmit and receive simultaneously. How-
ever, the radios communicating at GSU 1 and GSU 2 must transmit and receive in turn accord-
ing to the scheme in marked “Normal Phase” in Figure 11-3. This is an impossible situation,
if all the links must send and receive together. It is further complicated by adding a third and
further sites as shown.
Figure 11-2: GSU Scenario - Communicating distributed sites
Cascaded Sites using Shifted Phase Transmission Chapter 11
RADWIN 2000 User Manual Release 2.5.40 11-3
Cascaded Sites using Shifted Phase Transmission
The solution offered here is not a “universal cure”. The following conditions are necessary, but
in any specific case may not be sufficient:
• The GSU sites (marked 1, and 3 above) are sufficiently far apart as to ensure that
there is no mutual interference between communicating sites (1-2 and 2-3 above)
• There should be no interference between non-communicating sites (1 and 3 above).
To see how it works, we use Figure 11-2. The GSU towers are numbered and marked for
cascading, 1-2 and 2-3. There should
not
be a link between 1 and 3.
The GSU can synchronize the TDD timing of several sites enabling the cascading of consecu-
tive links without mutual interference.
To use cascading, the TDD timing of the even-ordered links (GSU 2 above) must be “shifted”
(Shifted Phase) and odd-ordered links (GSU 1 and GSU 3 above) must be “unshifted” (Normal
Phase). The phase shift is half of the Radio Frame Duration (RFD) from the chosen RFP. The
scheme is shown in Figure 11-3.
Since the GSU is always HSS master (HSM), at each GSU location, the GSU can “force” the
synchronization of its collocated radios. By half RFD shifting, alternate collocated sites can
talk to each other.
Figure 11-3: Phase shifted transmission - phase shift is 1/2 the RFD
Choice of normal or shifted phase is configurable per GSU using the RADWIN Manager.
GSU Redundancy
The GSU is designed to support redundancy, improving the robustness of a GSU based topol-
ogy.
In redundancy mode, two GSUs are installed at the same HSS site. One of them self-config-
ures to generate HSS sync signals. We will call it the Primary unit. The other one, the Second-
ary unit remains dormant merely polling the first GSU. If the Primary GSU fails, then the
Secondary GSU becomes active immediately. If the Primary unit becomes active again, it
remains dormant, reversing the original roles. The choice of the Primary GSU is random and
of no significance.
If the Primary GSU fails, and then the Secondary GSU also fails to receive sync signals from
its GPS, then it moves to self-generation HSM mode like an ordinary HSM ODU until its GPS
recovers.

GSU Installation
Overview
The GSU uses the same container and cabling as a WinLink 1000 unit.
Preparing the GSU for Use Chapter 11
RADWIN 2000 User Manual Release 2.5.40 11-5
Figure 11-5: General GSU configuration
In that respect, all of the considerations of Chapter 3, Chapter 17 and Chapter 18 of the
use Manual apply to the GSU.
It may be configured using the regular RADWIN Manager or Telnet.
Preparing the GSU for Use
Use the method of Chapter 19, Preloading an ODU with an IP Address to change the IP
address from the default (10.0.0.120). In the example screen captures below, we use
192.168.222.20 with Subnet Mask 255.255.252.0.
Mounting the GSU
Mount the GSU and antenna. Ensure that its ODU port connected to its PoE device and the
HSS cable is connected to the HSS unit as shown. The external LAN port of the PoE device is
connected to the managing computer. If you are accessing the GSU through a network it is
essential that you use the IP preloading method. The default IP address may be inaccessible
and you may not use the Local Connection method over a network.
Configuring the GSU
Getting Started
To configure the GSU, you log on to it, exactly as in Chapter 4.
The GSU Main Window
Here is the main window for GSU configuration:

The top five items in the GSU Monitor panel are taken from a satellite. The transmission
Phase may be Normal as shown or Shifted. It purpose, together with the Tx Ratio bar, will
be explained below.
The Status Box
Under normal operating conditions, it will be green as shown, indicating that it is synchro-
nized with a satellite.
If satellite synchronization is lost, then the GSU will function as an independent HSM and the
status box will change color:
The Main Menu
The main menu is a subset of the main menu applicable to the WinLink 1000. Notice that
there are no Installation or Configuration wizards. Such configuration as is necessary is car-
ried out using a modified version of Site Configuration for WinLink 1000.
Similarly, the Tool bar is a subset of that applicable to the WinLink 1000.

1. Setting the RFP for HSS
The GSU is automatically configured as HSS Master (HSM).
If the hub site consists only of WinLink 1000 units, then any suitable RFP may be chosen.
If there are one or more RADWIN 2000 units, you must use RFP B or E.
The permitted RFPs are also dependent on channel bandwidth and are color coded as fol-
lows:
Note
The 1000 and 2000 labels refer to WinLink 1000 and RADWIN 2000 radios,
respectively. The actual annotation seen may vary, but the intention should
be clear.
Note
Ensure that no other collocated ODU is configured as HSM.
