RADWIN 2000 User Manual Release 2.5.40 iiiRegulatory ComplianceGeneral NoteThis 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 - ComplianceThis 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.WarningIt 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.WarningIt 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.CautionOutdoor 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 ivIndoor 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 UnitsThis 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 MIIOperation of the equipment is only allowed under China MII 5.8GHz band regulation configuration with EIRP limited to 33 dBm (2 Watt).India WPCOperation of the equipment is only allowed under India WPC GSR-38 for 5.8GHz band regulation configuration.UnregulatedIn 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 PracticesApplicable 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.

RADWIN 2000 and specifically RADWIN 2000 PDH systems are ideally suited for a broad range of cellular backhaul deployment scenarios; they empower carriers to expand their pres-ence into remote and low ARPU areas, provide enhanced overlay coverage in urban spots, and can serve as a temporary or backup backhaul solution.Figure 1-1: Typical Cellular Backhaul application Broadband AccessWith RADWIN 2000 solutions, service providers can expand their service footprint rapidly and affordably, providing high-capacity services that match the ever-growing demand for high-quality, high-speed broadband.RADWIN 2000 is the ideal solution for last mile access, for large corporations requiring high capacity either or both IP or TDM traffic.Figure 1-2: Typical Broadband Access application
Mobility Applications Chapter 1RADWIN 2000 User Manual Release 2.5.40 1-5Figure 1-3: Typical WiFi Backhaul ApplicationMobility ApplicationsRADWIN 2000 radios have been successfully deployed in a variety of Mobility Applications:Border ControlRADWIN 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 SecuritySecuring 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 solutionsThis is a relatively new application and includes for example,»On-board surveillance»On-board monitoring and control»Passenger services including Internet accessFor further information about Mobility Applications, contact RADWIN Customer Support. Key Features of RADWIN 2000Some of the outstanding features of the RADWIN 2000 radio series are as follows:»E1/T1 + Ethernet in one SolutionRADWIN 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 CapacityThe RADWIN 2000 system provides a high-capacity link of 100 Mbps net throughput full duplex»Superior Spectral Efficiency
Key Features of RADWIN 2000 Chapter 1RADWIN 2000 User Manual Release 2.5.40 1-6Built 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 ProductsEvery 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 InterfaceThe 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) powerThe 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 performanceThe 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 1000Site 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 1RADWIN 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 interfaceThe 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 linkA 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 ViewSpectrum 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.»DiversityRADWIN 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 managementRADWIN 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 SecurityThe 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 1RADWIN 2000 User Manual Release 2.5.40 1-8CCM/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-CStandard 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.Components of a RADWIN 2000 LinkThe Outdoor Unit (ODU)The Radio Outdoor Unit (ODU)The ODU is the radio transceiver of the RADWIN 2000 system.

A Little Terminology Chapter 1RADWIN 2000 User Manual Release 2.5.40 1-16 A Little TerminologyIn 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.

Viewing and Printing Chapter 1RADWIN 2000 User Manual Release 2.5.40 1-19Figure 1-16: Site Configuration window with open Management panelViewing and PrintingThis manual is optimized for viewing online as a PDF file. To this end it uses an 11 point Tahoma typeface for main text. Tables for most part, use 7 or 8 point fonts. Here are a few pointers for hard-copy printing:• The text and table typefaces used are large enough to print the manual at two pages per sheet• For good legibility, use a commercial grade laser printer. A color printer is of course best, however a monochrome printer set to use gray-scale gives acceptable results• Better quality inkjet printers also give good output
RADWIN 2000 User Manual Release 2.5.40 2-1Chapter 2Site PreparationPlanning the Link SiteOverviewLink 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 SurveyIntroductionRADWIN 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 EquipmentStage 1: Preliminary Survey• Topological map of the area• Urban map of the area•CompassStage 2: Physical Survey• 100 meter tape measure
Stage 1: Preliminary Survey Chapter 2RADWIN 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 SurveyA 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 2RADWIN 2000 User Manual Release 2.5.40 2-3Stage 2: Physical SurveyThe 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 siteAdditional Outdoor Site RequirementsThe ambient outdoor operating temperature should be -35 to 60C (-31 to 140F).Additional Indoor Site RequirementsThe following requirements guarantee proper operation of the system:NoteIt is advisable to go on a clear day, so you can more easily see any obstructions between the two sites.NoteThe IDU - ODU cable length limit is 100m, in accordance with IEEE 10/100BaseT standards.
Stage 3: RF Survey Chapter 2RADWIN 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 condensingStage 3: RF SurveyThe 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 SitesInterference 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).NoteIt 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.
RF Planning for Dense Installations and Collocated Sites Chapter 2RADWIN 2000 User Manual Release 2.5.40 2-5• Decreasing the Tx Power of a link will reduce collocation interference (Site Configu-ration | Air Interface). NoteUse the Link Budget Calculator to determine the minimum Tx Power required to maintain link stability.

Connecting and Aligning ODUs / Antennas Chapter 3RADWIN 2000 User Manual Release 2.5.40 3-13Connecting and Aligning ODUs / AntennasYou 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.WarningWhen aligning the antennas, do not stand in front of a live antenna.
Connecting and Aligning ODUs / Antennas Chapter 3RADWIN 2000 User Manual Release 2.5.40 3-14Figure 3-14: Beep Sequence for antenna alignment8. 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 alignmentNoteThe 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.

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 4RADWIN 2000 User Manual Release 2.5.40 4-10A 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.NoteThe Dynamic Tx Ratio bar only appears for model RADWIN 2000 CNoteDuring 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.NoteAn 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

Installation Chapter 5RADWIN 2000 User Manual Release 2.5.40 5-7Step 3, Channel SettingsRADWIN 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 5-6: Channel Settings - Automatic Channel SelectionThe default frequency for the product is shown.To select channels to be used by the link:1. Select the installation frequency from the Installation Channel box.

The Quality bar pro-vides an indication of the link quality from No serv(ice) (red) to Ethernet + TDM (green) as shown in the bottom of Figure 5-7 above.5. Click Next.Step 4, Tx Power and Antenna SettingsThe Tx Power and Antenna Parameters dialog appears..Figure 5-9: Transmission Power and Antenna ParametersThe 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 AntennasEach 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 SitesWhen 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 5RADWIN 2000 User Manual Release 2.5.40 5-10MIMO ModeWith 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 ModeDiversity 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 SitesBy 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 OtherIn 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).
Installation Chapter 5RADWIN 2000 User Manual Release 2.5.40 5-11The air rates used in this mode are same as when using single antennas in both sites.Table 5-2 summarizes the situation:The rates used by RADWIN 2000 are shown in Table 5-3 below:Table 5-2: MIMO - Diversity settingsNumber of Antennas Mode Graphic Indication Max Full Duplex CapacitySite A Site B2 2MIMO 50 MbpsDiversity 25 Mbps2 1 25 Mbps1 2 25 Mbps1 1 25 MbpsTable 5-3: RADWIN 2000 Air ratesAntenna Modulation FEC Air-Rate [Mbps]Single BPSK 1/2 6.5Single QPSK 1/2 13Single QPSK 3/4 19.5Single 16QAM 1/2 26Single 16QAM 3/4 39Single 64QAM 2/3 52Single 64QAM 3/4 58.5Single 64QAM 5/6 65Dual BPSK 1/2 13Dual QPSK 1/2 26Dual QPSK 3/4 39Dual 16QAM 1/2 52Dual 16QAM 3/4 78Dual 64QAM 2/3 104

Your choice would typically be based on your experienced traffic load during periods of congestion.If you change the Transmission Ratio, you will be offered the following warning: Otherwise, click Yes to continue.
Installation Chapter 5RADWIN 2000 User Manual Release 2.5.40 5-19Limitations on the use of Asymmetric AllocationFor 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 CollocationThe 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.The Services and Rates dialog as shown in Figure 5-16 will be different:CautionIf you have active collocated links, or if you are uncertain of whether collocated links provide TDM services do not use this option now.

RADWIN 2000 User Manual Release 2.5.40 7-1Chapter 7Configuring the LinkOverviewThis 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 parametersThe Configuration Wizard has seven steps as shown in Table 7-1 below.

Configuration Chapter 7RADWIN 2000 User Manual Release 2.5.40 7-7Figure 7-6: Channel frequency optionsSelecting 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 frequencyThe 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 7RADWIN 2000 User Manual Release 2.5.40 7-8The 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 SettingsThe Tx Power and Antenna Settings window is similar to that for Installation:Figure 7-8: Transmission Power and Antenna ParametersAs 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 modeChanging Number of Antennas and Tx PowerTX Power, Antenna Gain and Cable LossIf you chose to configure either antenna, you are presented with the following window:
Configuration Chapter 7RADWIN 2000 User Manual Release 2.5.40 7-9Figure 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 AntennasSingle/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:CautionIn 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 7RADWIN 2000 User Manual Release 2.5.40 7-10Switching Between MIMO and Diversity ModesA 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 SettingsFigure 7-10: HSS SettingsThe Synchronization Status dialog box displays the current status of each side of the link.

Site Management: IP Address, VLAN and Protocol Chapter 8RADWIN 2000 User Manual Release 2.5.40 8-5Figure 8-4: HSS StatusSite Management: IP Address, VLAN and ProtocolConfiguring the ODU AddressEach 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 8RADWIN 2000 User Manual Release 2.5.40 8-6Figure 8-5: Management Addresses - Site Configuration dialog box5. 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 SettingsVLAN 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.NoteIf performing configuration from the RADWIN Manager, the IP address is that entered from the Login window.CautionVLAN 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 8RADWIN 2000 User Manual Release 2.5.40 8-72. 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 SettingsLost or forgotten VLAN IDIf the VLAN ID is forgotten or there is no VLAN traffic connected to the ODU, then reset the relevant ODU.CautionChanging 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 8RADWIN 2000 User Manual Release 2.5.40 8-8During 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 AccessFor 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:Figure 8-7: Enable/Disable Telnet AccessDisplaying the InventoryTo view the inventory data1.

Otherwise, it works the same way as the corresponding item on page 5-8.RADWIN Manager Community StringsThe 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 8RADWIN 2000 User Manual Release 2.5.40 8-10Editing Community StringsThe 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 StringForgotten Community stringIf 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 8RADWIN 2000 User Manual Release 2.5.40 8-11Figure 8-11: Alternative Community Dialog boxLink Lock Security FeatureLink 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 8RADWIN 2000 User Manual Release 2.5.40 8-123. 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 8RADWIN 2000 User Manual Release 2.5.40 8-13The Link Lock check-box is now unavailable.5. If required, repeat the procedure for Site B.Setting the Date and TimeThe 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.NoteTo 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.NoteThe 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 8RADWIN 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:216.218.192.202You 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 Configuration5. 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.Figure 8-13: Change Date and Time If you used an NTP Server, you will see a window like this:1. Greenwich Mean Time

Click OK to return to the Configuration dialog.Ethernet PropertiesConfiguring 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 8RADWIN 2000 User Manual Release 2.5.40 8-16Figure 8-15: Bridge, VLAN and MIR ConfigurationODU ModeThis 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 timeThis 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.NoteRADWIN 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.NoteChanging 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 8RADWIN 2000 User Manual Release 2.5.40 8-17The following table shows the appropriate configuration for several common scenarios. Both link sites must be configured with the same parameter:Configuring Ethernet Ports ModeThe 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.VLAN Tagging for Ethernet Service: ConfigurationIf you are using a PoE device, this feature is unavailable. You may skip this section.Table 8-1: ODU mode configuration for common scenariosScenario ODU Mode IDU Aging TimeStandard (default) Configuration for Ethernet Applications Bridge 300 secRapid network topology changes where fast aging is required Hub 1 secCautionYou 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.NoteIt 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 8RADWIN 2000 User Manual Release 2.5.40 8-18To set up VLAN tagging for Ethernet Service, click the VLAN Configuration... button in Figure 8-15. The following window is displayed:Figure 8-16: VLAN tag settingsThe choices for Ingress Mode are - and for Egress Mode are - CautionVLAN 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.NoteIf you are using a new style IDU-E, the SFP row will not appear.
Setting the Maximum Information Rate (MIR) Chapter 8RADWIN 2000 User Manual Release 2.5.40 8-19The 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 MIRThe 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 forThe 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 | EthernetThe Configuration dialog box opens.NoteThe 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 CThe MIR setting is independent per direction.

Events, Alarms and Traps Chapter 9RADWIN 2000 User Manual Release 2.5.40 9-13Figure 9-15: Threshold configuration dialog boxRSL ThresholdsTwo 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 ThresholdA counter is maintained, of the number of second intervals during which Tx power exceeds this threshold.BBER ThresholdThe 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 - CapacityThis 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 - TrafficThe number of seconds count that received traffic exceeded this threshold. It can be used to measure traffic peaks.Events, Alarms and TrapsThe Events LogThe Events Log records system failures, loss of synchronization, loss of signal, compatibility problems and other fault conditions and events.NoteThe foregoing event types include events from all links for which this managing computer has been defined as the traps address.

Replacing an ODU Chapter 9RADWIN 2000 User Manual Release 2.5.40 9-20Use the following table to troubleshoot faults in the system:.Replacing an ODUPrior 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 configurationIf 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 configurationThe new ODU can be configured manually according to the link configuration.

RADWIN 2000Broadband Wireless Transmission SystemUSER MANUALRELEASE 2.5.40Part 2: Site SynchronizationUM 2000-2540/02.11
RADWIN 2000 User Manual Release 2.5.40 10-1Chapter 10Hub Site SynchronizationWhat 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.NoteHSS 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 10RADWIN 2000 User Manual Release 2.5.40 10-2Figure 10-1: Interference caused by collocated unitsAdding 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 10RADWIN 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 InstallationConnecting an HSS UnitA 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 10RADWIN 2000 User Manual Release 2.5.40 10-44. 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 UnitFigure 10-5: HSS Wiring schematicThe 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.Figure 10-6: HSS sync signal path with ODU 1 as HSS Master
Using More than One HSS Unit Chapter 10RADWIN 2000 User Manual Release 2.5.40 10-5Using More than One HSS UnitIn a large collocation site, several HSS units may be cascaded (daisy-chained) subject to the following conditions:Condition 1: Cabling Sequence1. 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 units4. 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 10RADWIN 2000 User Manual Release 2.5.40 10-6Figure 10-8: Cascading three HSS units6. 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 LengthThe 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 mHm be the length of the cable joining HSS unit m to HSS unit m+1One HSS unit with five collocated ODUsTwo cascaded HSS units as shown in Figure 10-7Three cascaded HSS units as shown in Figure 10-8HSS Error NotificationIn 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:NoteIf an ODU is disconnected from an HSS unit, then all remaining ODUs must be moved up or down to maintain the connectivity.PathLength L11 2L12 2L13+2L14 L15+++=PathLength L11 2L12 2L13 2L14+2+L15+H12L29 2+L28 2+ L27L26++++=PathLength L11 2L12 2L13 2L14+2+L15+H12L29 2+L28 2+ L272L26+H22L32 2L33 2L34 L35++++++ ++=

RFP: RADWIN 2000 Considerations Chapter 10RADWIN 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:

RFP: WinLink 1000 Considerations Chapter 10RADWIN 2000 User Manual Release 2.5.40 10-11RFP: 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 bandwidthTable 10-4: Asymmetric Allocation with Collocated Links - ScenariosHSS Master HSS Client Scenario: If you try to...

If a wrong HSM pulse is detected, a WinLink 1000 will resync, adapting to the HSM RFP and continue whereas RADWIN 2000 may stop.Table 10-6: External Pulse StatusHSS Sync Status Meaning Color codeGenerating ODU is HSM and generates the sync pulseGreenDetected ODU is HSC and detects the sync pulseNot detected ODU is independentGenerating and detected HSM, but other HSM presentOrangeGenerating and Improperly DetectedRADWIN 2000 ODU is HSM, but but detects a WinLink 1000 HSM signal that is not RFP ENot detected HSC but no HSM presentImproperly detectedHSC but HSM pulse doesn’t fit the HSC as configured.

RADWIN 2000 User Manual Release 2.5.40 11-1Chapter 11Using the RADWIN GSUWhat is it forThe 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 FunctionalityThe 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 ScenariosIndependent Distributed SitesIn 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 11RADWIN 2000 User Manual Release 2.5.40 11-2pendent dis tributed sitesFigure 11-1: GSU Scenario - Independent distributed sitesMultiple Distributed Sites with CommunicationWhat 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 11RADWIN 2000 User Manual Release 2.5.40 11-3Cascaded Sites using Shifted Phase TransmissionThe 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 RFDChoice of normal or shifted phase is configurable per GSU using the RADWIN Manager.GSU RedundancyThe 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.

Preparing the GSU for Use Chapter 11RADWIN 2000 User Manual Release 2.5.40 11-5Figure 11-5: General GSU configurationIn 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 UseUse 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 GSUMount 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 GSUGetting StartedTo configure the GSU, you log on to it, exactly as in Chapter 4.The GSU Main WindowHere is the main window for GSU configuration:
