Avoiding Hazards182 Avoiding Hazards2.1 Preventing Overexposure to RF EnergyCaution To protect from overexposure to RF energy, install the radios for the 500 family of PTPwireless solutions so as to provide and maintain the minimum separation distances from all personsas shown in Table 3.When the system is operational, avoid standing directly in front of the antenna. Strong RF fieldsare present when the transmitter is on. The Outdoor Unit (ODU) must not be deployed in alocation where it is possible for people to stand or walk inadvertently in front of the antenna.At these and greater separation distances, the power density from the RF field is below generallyaccepted limits for the general population.Note These are conservative distances that include compliance margins.2.1.1 Calculations for Separation Distances and Power Compliance MarginsLimits and guidelines for RF exposure come from:•US FCC limits for the general population. See the FCC web site at http://www.fcc.gov,and the policies, guidelines, and requirements in Part 1 of Title 47 of the Code of FederalRegulations, as well as the guidelines and suggestions for evaluating compliance in FCC OETBulletin 65.•Health Canada limits for the general population.See the Health Canada web site athttp://www.hc-sc.gc.ca/ewh-semt/pubs/radiation/99ehd-dhm237/limits-limites_e.htmland Safety Code 6.•ICNIRP (International Commission on Non-Ionizing Radiation Protection) guidelines for thegeneral public. See the ICNIRP web site at http://www.icnirp.de/ and Guidelines forLimiting Exposure to Time-Varying Electric, Magnetic, and Electromagnetic Fields.The applicable power density exposure limits from the documents referenced above are:•6 W/m2 for RF energy in the 900-MHz frequency band in the US and Canada.•10 W/m2 for RF energy in the 2.4-, 5.2-, 5.4-, and 5.8-GHz frequency bands.Peak power density in the far field of a radio frequency point source is calculated as follows:S=P.G4πd2(1)Where:-S= power density W/m2P= Maximum Average transmit power capability of the radio WG= total Tx gain as a factor, converted from dBd= distance from point source m

Getting Started223.3 Product DescriptionThis User Manual is specifically written for the 500 family of point-to-point broadband wirelesssolutions. The PTP 500 Series Bridge has been developed to provide Point-to-Point data connec-tivity via a 5.4 GHz or 5.8 GHz wireless Ethernet bridge operating at broadband data rates. ThePTP 500 Series Bridge is aimed at a wide range of applications. An example application is anenterprise that has a requirement to connect together the Local Area Network (LAN) of two ormore buildings as shown in Figure 1.Figure 1 Typical PTP 500 Series Bridge DeploymentThe PTP 500 Series Bridge offers true non-line-of-sight (NLOS) operation by using a combinationof Orthogonal Frequency Division Multiplexing (OFDM) modulation and Multiple-Input Multiple-Output (MIMO) techniques. These technologies enable the PTP 500 Series Bridge to drive throughfoliage and around buildings to such an extent that almost universal coverage can be expected atshort range.A PTP 500 Series Bridge system consists of a pair of identical devices that are deployed one ateach end of the link. At installation, the user sets up one unit as the Master and the other as theSlave. Either unit can be configured as Master or Slave.Each end of the link consists of:•An integrated (or connectorized - see section 13) outdoor transceiver unit containing all theradio and networking electronics hereafter referred to as the Outdoor Unit (ODU).•An indoor connection box containing a mains power supply, status indicators and networkconnection port. Hereafter referred to as the Power Indoor Unit Plus (PIDU Plus).
Getting Started23A pair of units is normally supplied pre-configured as a link.The network connection to a PTP 500 Series Bridge is made via a 100BaseT Ethernet connection.Power is provided to the ODU over the 100BaseT Ethernet connection using a patented non-standard powering technique.Power is fed into the PTP 500 Series Bridge PIDU Plus from the mains via a standard “figure ofeight” mains plug. Connection between the ODU and PIDU Plus is made using standard CAT5eoutdoor UV resistant cable. Connection between the PIDU Plus and the Network Equipment ismade using standard CAT5e cable.
Getting Started243.3.1 The Outdoor Unit (ODU)The ODU is a self-contained unit. It houses both radio and networking electronics. The ODUfor the PTP 500 Series Bridge should only be deployed using the supplied PTP 500 Series BridgePIDU Plus. Figure 2 shows an installation example of a PTP 500 Series ODU with a Motorolalightning protection unit (PTP-LPU).Figure 2 PTP 500 Series BridgeOutdoor Unit (ODU) with PTP-LPU
Getting Started253.3.2 PIDU Plus – PTP 500 Series BridgeThe PTP 500 Series Bridge PIDU Plus is used to generate the ODU supply voltage from themains supply and inject this supply voltage into the 1000BaseT Ethernet connection to the ODU.Connection uses a CAT5e cable using standard RJ45 wiring.CAUTION: Care should be taken not to connect equipment other than an ODU for the PTP 500Series Bridge to a PIDU Plus ODU port as equipment damage may occur. The PTP 500 SeriesBridge PIDU Plus is not interchangeable with the PTP 400 Series PIDU Plus but can be usedwith the PTP 600 Series.Figure 3 Power Indoor Unit(PIDU Plus) – PTP 500 SeriesThe front panel contains indicators showing the status of the power and Ethernet connections.The power indicator is illuminated when the PIDU Plus is receiving mains power.The Ethernet indicator normally illuminates when the Ethernet link is working, flashing whenthere is Ethernet activity. The fact that it lights also indicates that the ODU is powered. Atpower up the LED will flash 10 times to indicate that a correct start up sequence has occurred.See Section 10 “Fault Finding” for further fault finding information.At the bottom of the PIDU Plus is an entry point for the PIDU Plus to ODU cable, the 100BaseTEthernet network port and the Recovery switch.Figure 4 PIDU Plus Recovery Switch Location
Getting Started26The Recovery switch is used to recover the unit from configuration errors or software image corrup-tion. To put a PTP 500 Series Bridge into Recovery mode the Recovery switch should be pressedthen the power applied. The Recovery switch should be kept pressed for at least 30 seconds afterthe power has been applied. Full instruction on the recovery mode can be found in Section 9“Recovery Mode”.A simple reboot can be performed by removing and re-applying the mains power to the PTP 500Series Bridge PIDU Plus.On the left hand side of the PIDU Plus, 48V DC input and output connections can be found. Theseare used to power the PTP 500 Series Bridge from an external DC source or to provide a levelof power supply redundancy, as shown in Section 3.3.3 “Redundancy and Alternate PoweringConfigurations”.WARNING: When using alternate DC supplies the supply MUST comply with the followingrequirements:•The voltage and polarity is correct and is applied to the correct terminals in the PIDU Plus•The power source is rated as SELV•The power source is rated to supply at least 1A continuously•The power source cannot provide more than the Energy Hazard Limit as defined by IEC/EN/UL6090,Clause 2.5, Limited Power (The Energy Hazard Limit is 240VA)Also on the left hand side of the PTP 500 Series Bridge PIDU Plus, connectors and jumpers canbe found that allow the remote connection of power LED, Ethernet LED and Recovery switch.The connection instructions can be found in Section 3.3.4 “Remote LEDs and Recovery Switch”.The input supply range for the 500 Series PIDU Plus is 90V-264V AC, 47-63Hz. Mains connectionto the PIDU Plus is made using a standard “figure of eight” mains lead as shown in Figure 5.Figure 5 PTP 500 Series Bridge PIDUPlus Power Input
Getting Started273.3.3 Redundancy and Alternate Powering ConfigurationsNOTE: The use of DC supplies of less than 55v will reduce the usable distance between the PIDUPlus and ODU see Figure 6.Figure 6 PTP 500 Series Bridge PIDUPlus to ODU Cable Length GraphCAUTION: The maximum distance from the ODU to the connected network equipment is 100m(330 ft) when using 100BaseT.3.3.3.1 External DC Supply OnlyFor use where there is no mains supply.Figure 7 External DC Supply Only

Getting Started293.3.4 Remote LEDs and Recovery SwitchThe PTP 500 Series Bridge PIDU Plus provides a facility to connect remote LEDs and Recoveryswitch allowing the PIDU Plus to be mounted inside an enclosure. At the left hand end of the PIDUPlus under the ODU connection cover can be found a PCB header and three jumpers. JumpersJ906 and J907 should be removed and connection to the remote LEDs and Recovery switch madeto J908 as shown in Figure 10.Figure 10 Remote LED and Recovery Switch Wiring3.3.5 Cables and connectorsThe cable used to connect the PTP 500 Series Bridge PIDU Plus to the ODU can be any standardCAT5e type provided that it is suitable for outdoor deployment. Motorola recommends that cablesto the specification below be used:Cable: Superior Essex BBDGE CAT 5eConnector Type: Tyco, 5-558530-1Gland: Motorola WB1811
Getting Started30Caution: Failure to use the recommended (or equivalent) standard of cable may invalidate thesystem’s safety certification.The cable used to connect the PTP 500 Series Bridge PIDU Plus to the users Network Equipmentcan be any standard CAT5e Cable.The PIDU Plus to ODU and the PIDU Plus to Network Equipment cables may be unscreened(UTP) or screened (STP). However, unscreened cables reduce the system’s ability to cope withnearby lightning strikes. If lightning activity is common in the area of deployment, the use ofscreened cable is highly recommended. See Section 11 “Lightning Protection”.The PIDU Plus provides screen continuity between the ODU and Network Equipment connections.Note:The ODU network connection implements automatic MDI/MDI-X sensing and pair swappingallowing connection to networking equipment that require cross-over cables (MDI-X networks) orstraight-through cables (MDI Networks).3.3.6 PTP and Lightning ProtectionThe PTP 500 Series Bridge PIDU Plus meets the low level static discharge specifications identifiedin Section 17 “Specifications”, but does not provide lightning or surge suppression. Installationswill generally require lightning or surge suppression, a separate Ethernet surge suppressor mustbe used and appropriately earthed. Suitable surge suppressors can be sourced from your MotorolaPoint-to-Point Distributor or Solutions Provider. See Section 11 “Lightning Protection”.3.3.7 Mounting BracketsThe PTP 500 Series Bridge is supplied with a mounting bracket suitable for mounting the ODUto a pole of 50mm (2”) to 75mm (3”) in diameter. For more details on mounting, see Section 7“Installation”.The bracket allows for adjustment in both azimuth and elevation. The bracket may be splitallowing the pole mount section of the bracket to be mounted to the pole first. This allows theinstaller to take the weight of the unit and secure it, one handed, with a single mounting bolt.The PIDU Plus can either be desk or wall mounted. The preference is wall mounted with thecables dressed to a cable channel. Wall mounting is achieved by screwing through the mountinglugs on either side of the unit. Remember to leave space for access to the Recovery button. SeeSection 3.3.2 “PIDU Plus – PTP 500 Series Bridge”.3.3.8 Configuration and ManagementConfiguration and Management of the PTP 500 Series Bridge is implemented using an inbuilt webserver hosting a number of Configuration and Management web pages. This approach allows Con-figuration and Management to be carried out on any standard web browsing technology. The PTP500 Series Bridge can also be managed remotely using the SNMP management protocol. Connec-tion to the bridge is via the Ethernet connection carrying the bridge network traffic. Connectionto the unit is via a preset IP address. This address can be changed via the Network InterfaceConfiguration web page. A full explanation of the available web pages and their use can be foundin Section 8 “Web Page Reference”.
Getting Started313.4 WarrantyMotorola’s standard hardware warranty is for one (1) year from date of shipment from Motorolaor a Motorola Point-to-Point Distributor. Motorola warrants that hardware will conform to thecurrent relevant published specifications and will be free from material defects in material andworkmanship under normal use and service. Motorola shall within this time, at its own option,either repair or replace the defective product within thirty (30) days of receipt of the defectiveproduct. Repaired or replaced product will be subject to the original warranty period but not lessthan thirty (30) days.Motorola warranty for software is described in details in Section 16.5.1 “Motorola Inc. End UserLicense Agreement”.
Product Architecture324 Product ArchitectureThe PTP 500 Series Bridge consists of an identical pair of units deployed one at each end of thelink. The radio link operates on a single frequency channel in each direction using Time DivisionDuplex (TDD). One unit is deployed as a master and the other as a slave. The master unit takesresponsibility for controlling the link in both directions. The non-line-of-sight (NLOS) aspects ofthe product are provided by Multiple-Input Multiple-Output (MIMO), coupled with OrthogonalFrequency Division Multiplexing (OFDM) modulation.The PTP 500 Series Bridge has been developed to operate within license exempt frequency bands.The current product range supports:•ETSI 5.4 GHz band B (5.470-5.725 GHz)•ETSI 5.8 GHz band C (5.725-5.850 GHz) and the USA 5 GHz ISM band (5.725-5.850 GHz)The PTP 500 Series Bridge has been designed to coexist with other users of the band in anoptimal fashion using a combination of Transmit Power Control (TPC), Spectrum Managementfunctionality and Antenna beam shape.In order to maintain link availability, the product employs adaptive modulation techniques thatdynamically reduce the data rate in severe or adverse conditions. The PTP 500 series provideswireless Ethernet bridging between two fixed locations. To be more precise, it forwards Ethernetframes as a two-port transparent heterogeneous encapsulation bridge, meaning that each bridgeforwards frames between two dissimilar interfaces (Ethernet and wireless), encapsulating EthernetMAC frames within a PTP MAC frames for transmission at the wireless interface. A link consistingof a pair of back to back bridges appears to the data network to be very similar to a standardtwo-port Ethernet bridge.The PTP500 series provides two egress queues in each direction, classifying Ethernet frames intoone of the two prioritised queues based on inspection of the user priority field (802.1p) in theIEEE802.1Q VLAN tag. Untagged frames receive a default priority. The queuing method isstrict priority. The bridge does not implement any VLAN functions for bridged frames apart frominspection of the priority field, and consequently the bridge forwards tagged and untagged Ethernetframes regardless of VLAN ID and without modification of any protocol header fields..The management function of the PTP 500 Series Bridge is logically equivalent to a separate protocolstack with virtual point of attachment at the Ethernet interface. This is illustrated in Figure 11.
Product Architecture33Figure 11 PTP 500 Series Bridge Layer DiagramEach unit in the link is manageable through an IP connection. Standard IP protocols are utilizedfor all management functions e.g., HP, SNMP, etc. The unit can be configured to use VLAN tagson the management interfaces.The PTP 500 Series Bridge is fully software upgradeable. New software images are first downloadedfrom the Motorola website http://www.motorola.com/ptp to a convenient computer. Theimage is then uploaded to the ODU via the web management page described in Section 8.3.6“Software Upgrade”. The compressed image is first loaded into RAM and check-summed. If thecompressed image transfer has completed successfully the image is decompressed and written toflash memory. On completion of this process the unit can be rebooted to use the newly uploadedimage. Should this process fail, the unit will revert to a protected compressed image installedduring manufacturing to allow the unit to be recovered.
General Considerations345 General Considerations5.1 Spectrum PlanningThe PTP 500 Series Bridge has four frequency variants in its product range.Band Definition FrequencyCoverageVariable ChannelWidthChannelRaster5.4 GHz ETSI 5 GHz band B, USA UNIIBand5470-5725 MHz 15 MHz 5 MHz5.8 GHz USA ISM Band / ETSI 5 GHzband C5725-5850 MHz 15 MHz 5 MHzTable 5 PTP 500 Series Bridge VariantsNote: for 5.4 GHz and 5.8 GHz, use of the product is allowed according to local regulations.There are two distinct approaches to spectrum planning:•First an operator can utilize the default spectrum management mode i-DFS (intelligent Dy-namic Frequency Selection). This mode uses the PTP 500 Series Bridge ability to measure theinterference levels in all channels to build up a picture of the interference / noise levels in allchannels. The PTP 500 Series Bridge uses statistical techniques to select the most appropri-ate transmit and receive channels. i-DFS can be influenced in its channel decision process byselectively barring channels from use. The use of this functionality is described in detail inSection 8.3.7 “Spectrum Management”.•Second, when detailed control of the spectrum allocation is required, it is recommended thatthe fixed frequency mode is used to statically allocate transmit and receive channels.
General Considerations355.2 Region CodesThe PTP 500 Series Bridge uses a system of Region Codes to control the operation of the radiolink. The Region Code is set by a License Key.Caution: To meet the regulatory requirements of your region you should set the correct RegionCode by obtaining a new License Key from your reseller or distributor.RegionCodeFrequencyBandRegulatory BodyorCountriesMaxTxPowerEIRPLimitOperationalRestrictions (seeSection 5.3“OperationalRestrictions”)1 5.8 GHz FCC Compliant (e.g.USA, Canada,Taiwan, Brazil)25 dBm None Reduced TX Powerat Band Edges seeSection 5.6.2 “5.8GHz Transmit PowerReduction at theBand Edges”2 5.8 GHz China 10 dBm 33 dBm3 5.8 GHz Australia, HongKong13 dBm 36 dBm4 5.8 GHz UK 12 dBm 35 dBm Radar AvoidanceEnabled and RTTT(Road Transport andTraffic Telematics,5795 to 5815 MHzchannels cannot beused)5 5.8 GHz Singapore -3 dBm 20 dBm6 5.8 GHz Eire 10 dBm 33 dBm7 5.4/5.8 GHz Unregulated DFSand RTTT25 dBm None Radar AvoidanceEnabled and RTTT(Road Transport andTraffic Telematics,5795 to 5815 MHzchannels cannot beused)8 5.4 / 5.8 GHz Unregulated InternalUse25 dBm None

General Considerations37Note: For Region Code 16, the EIRP limit is approximately 63 dBm + 10 x Log(360/AntennaAzimuth BW.When shipped from the factory units3are configured as follows:•PTP 500 Series Bridge 5.4 GHz – Region Code 264•PTP 500 Series Bridge 5.8 GHz – Region Code 15.3 Operational Restrictions5.3.1 Radar AvoidanceRadar Avoidance requires that equipment used in the region:•Detects interference from other systems and avoids co-channel operation with these systems,notably radar systems.•Provide on aggregate a uniform loading of the spectrum across all devices, i.e. Fixed Frequencyoperation is not allowed.•Radar avoidance is not applicable to the PTP54600 product.To address the primary aims the Spectrum Management algorithm implements a radar detectionfunction which looks for impulsive interference on the active channel only. If impulsive interferenceis detected Spectrum Management will mark the current active channel as having detected radarand initiate a channel hop to an available channel. The previous active channel will remain in theradar detected state for thirty minutes after the last impulsive interference pulse was detected.After the thirty minutes have expired the channel will be returned to the available channel pool.The radar detection algorithm will always scan the active channel for 60 seconds for radar interfer-ence before using the channel. This compulsory channel scan will mean that there is a 60 secondsservice outage every time radar is detected and that the installation time is extended by 60 secondseven if there is found to be no radar on the channel.NOTE: On system installation or start-up this extends the initial scan time of the Master unitby 60 seconds. To address the “provide aggregate uniform loading of the spectrum across alldevices” requirement, the channel selection algorithm will choose a channel at random from a listof available channels. The channel selection algorithm is initiated at link initialization and whenradar interference is detected.Note that 5.4 GHz and 5.8 GHz are different products.3Note that the Quickstart Guide also contains the license keys for region 12 and 13.4

The channelraster is set to even center frequencies. See Figure 14.5.6.2 5.8 GHz Transmit Power Reduction at the Band EdgesOperation at or near the 5.8 GHz band edges can results in a lower maximum transmit power.In some configurations the PTP 500 Series Bridge solution reduces the power when operating atthe edge channels. The amount of reduction, if any, is dependent on the region code of the regionof operation. This currently only affects systems configured with Region Code 1. The powerreduction in the edge channels for 15 MHz is presented in Table 6 (for region code 1 ONLY).

Operation of thesystem will depend on obstacles in the path between the units. Operation at 40 km (25 miles) orabove will require a near line-of-sight path. Operation at 100m (330 ft) could be achieved with oneunit totally obscured from the other unit, but with the penalty of transmitting at higher powerin a non-optimal direction, thereby increasing interference in the band. This subject is covered inmore detail in Section 6.1.3 “Path Loss Considerations”.5.8 Networking InformationThe PTP 500 Series Bridge operates as a transparent Ethernet bridge. Each unit requires an IPaddress. This IP address is for management purposes only and it plays no part in the operationof the system. IP addresses are assigned during initial configuration as described in Section 7.2“Installation Procedure”.5.9 Lightning Protection and regulationsThe amount of lightning protection is dependent on regulatory requirements and the end userrequirements. The standard ODU for the PTP 500 Series Bridge is fitted with surge limitingcircuits and other features to minimize the risk of damage due to nearby lightning strikes. Thesestandard features may require some additional equipment to be configured as part of the systeminstallation to be fully effective. Motorola recommends the use of screened cable and LightningProtection units to protect connected equipment from nearby strikes.NOTE: The PTP 500 Series Bridge is not designed to survive direct lightning strikes. For thisreason the unit should not be installed as the highest point in a localized area, unless specificprecautions are taken. See Section 11 “Lightning Protection”.5.10 Electrical RequirementsThe PTP 500 Series Bridge requires one mains supply outlet at each end of the link to plug in thePIDU Plus units (Section 3.3.2 “PIDU Plus – PTP 500 Series Bridge”).
Site Planning426 Site Planning6.1 Site Selection CriteriaThe following are guidelines for selecting the installation location of the ODU and PIDU Plus fora PTP 500 Series Bridge.6.1.1 ODU Site SelectionWhen selecting a site for the ODU the following should be taken into consideration:•It is not possible for people to stand or walk inadvertently in front of the antenna•Height and location to achieve the best radio path•Height in relation to other objects with regard to lightning strikes•Aesthetics and planning permission issues•Distance from the ODU and connected Network equipment (Maximum cable run from the ODUto the connected equipment is 100m [330 ft])•Distance from the PIDU Plus to the ODU (Maximum cable run from the PIDU Plus to theODU is 300m [990 ft] when using the Fiber interface)6.1.2 PTP 500 Series Bridge PIDU Plus Site SelectionWhen selecting a site for the PIDU Plus the following should be taken into consideration:•Availability of a mains electricity supply•Accessibility for viewing status indicators and pressing Recovery switch.6.1.3 Path Loss ConsiderationsThe path loss is the amount of attenuation the radio signal undergoes between the two ends of thelink. The path loss is the sum of the attenuation of the path if there were no obstacles in the way(Free Space Path Loss), the attenuation caused by obstacles (Excess Path Loss) and a margin toallow for possible fading of the radio signal (Fade Margin).Lfree_space +Lexcess +Lfade +Lseasonal <Lcapability (3)WhereLfree_space = Free Space Path Loss dBLexcess = Excess Path Loss dBLfade = Fade Margin Required dBLseasonal = Seasonal Fading dBLcapability = Equipment Capability dB
Site Planning436.1.4 DefinitionsThe equipment capability is given in Table 7,Table 9 (IP Mode) and Table ??,Table 10 (TDMMode). Each table gives Link Loss Output Power and System Thresholds for PTP 500 SeriesBridge in all modulation modes for the channel bandwidth 15 MHz. Adaptive Modulation willensure that the highest throughput that can be achieved instantaneously will be obtained takingaccount of propagation and interference. The calculation of Equation 3 needs to be performedto judge whether a particular link can be installed. When the link has been installed, web pagesprovide information about the link loss currently measured by the equipment both instantaneouslyand averaged. The averaged value will require maximum seasonal fading to be added, and thenthe radio reliability of the link can be computed.For minimum error rates on TDM links the maximum modulation mode should be limited to64QAM 0.75.The values for (BPSK) are static receive sensitivity measurements. The other values are staticreceive sensitivity measurements with an AMOD threshold applied. The AMOD threshold appliedis for a benign radio channel.Sensitivity: Sensitivity is defined as the combined receive input signal level on both horizontaland vertical inputs that produces a Null Bit Error Ratio of 3x10-7.Output Power: The output power is for a centre channel in Region 1. The output power will bereduced on the edge channels and may vary if different region codes are selected.AMOD Threshold: The AMOD threshold is the combined receive input signal level on bothhorizontal and vertical inputs that results in the link consistently entering the receive modulationmode under consideration as the signal level is increased.System Threshold: Thresholds for all modes except BPSK are for the relevant link optimizationAMOD thresholds. System threshold for BPSK is the RPSK receive sensitivity.Max Link Loss: The maximum link loss for each modulation mode is derived from the AMODthreshold for that mode (sensitivity threshold for BPSK) and the maximum Region 1 centre channeloutput power. The figures assume integral antennas with 23dBi (5.8 GHz and 5.4 GHz) gain areused.

BE LIABLE FOR ANY INJURY TO ANY PERSONSOR ANY DAMAGE CAUSED DURING THE INSTALLATION OF THE MOTOROLA PTP 500SERIES PRODUCT.7.6 Mounting the ODUsThe ODU mounting bracket is designed to ease installation by fixing the bracket to a pole andthen bringing the ODU into position using a single bolt fixing. The ODU should be mounted usingthe following steps ensuring that the cable entry is at the bottom.The ODU mounting bracket is designed to work with poles with diameters in the range 50mm (2”)to 75mm (3”).Step 1: Mount thebracket to the pole.Step 2: Mate the unit tothe bracket together andtighten the nut and bolt.Pole diameters of 25mm (1”) to 50mm (2”) can be accommodated by inverting the back of thebracket as shown in Figure 15.Figure 15 Mounting to pole diameters25mm (1”) to 50mm (2”)When adjustment is complete tighten all bolts to 14Nm (11lb ft).CAUTION: Do not over tighten the bolts as bracket failure may occur.
Installation48The enclosure and mounting brackets of the PTP 500 Series Bridge product range are capable ofwithstanding wind speeds up to 151mph (242kph). The installer should ensure that the structurethe bridge is fixed to is also capable of withstanding the prevalent wind speeds and loads. SeeSection 12 "Wind Loading".The integral safety loop should be used both for hoisting the ODU up a mast or building and intoposition, and also as a fixing point to secure a permanent safety lanyard from the tower/buildingto the ODU in case of mounting failure.Figure 16 Integral Safety LoopThe length of the safety lanyard must not exceed 1m (approx 3 ft) in length. The lanyard shouldbe made from a material that does not degrade in an outdoor environment.The safety lanyard must be fixed to a separate fixing point that is not part of the direct mountingsystem for the ODU.7.7 Connecting Up7.7.1 Preparing the PIDU Plus To ODU CableNOTE: The maximum cable length between the ODU and the user’s Network Equipment is 100m(330 ft). Cable lengths up to 300m (984 ft) can be used where the PIDU Plus to ODU cable issupplying power only, i.e., when using the PTP 500 Series Bridge Optical Interface.
Installation49The cable should be assembled as shown in Figure 17:Figure 17 Correct Cable Preparation for the Recommended CableBoth ends of the ODU cable are terminated in the same way. The above procedure should berepeated for the PIDU Plus end of the cable when the cable routing process is complete. Thisassumes that the installation uses PTP LPUs. If not, then the PIDU Plus end of the cable doesnot require a Gland, but just the RJ45.NOTE: The PIDU Plus end of the cable does not use a cable gland.

Installation52Should it be necessary to disconnect the PIDU Plus to ODU cable at the ODU, this can beachieved by removing the weather proofing gland and depressing the RJ45 locking tab with asmall screwdriver as shown below:Figure 22 Disconnecting the ODUCAUTION: Ensure that power is removed from the system at the PIDU Plus to prevent damageto the ODU while making or breaking the connection.7.7.4 Routing the CableAfter connecting the cable to the ODU it can be routed and secured using standard cable routingand securing techniques. When the cable is in place it can then be cut to the desired length at thePIDU Plus prior to connection to the PIDU Plus7.7.5 Fitting a Lightning Protection UnitIf you have opted to fit a Lightning Protection unit, this should be installed by following themanufacturer’s instruction. For recommended types see Section 11 "Lightning Protection”7.7.6 Grounding the InstallationThe Outdoor Unit (ODU) must be properly grounded to protect against power surges. It is theuser’s responsibility to install the equipment in accordance with Section 810 of the National ElectricCode, ANSI/NFPA No.70-1984 or Section 54 of the National Electrical Code in the country ofinstallation. These codes describe correct installation procedures for grounding the outdoor unit,mast, lead-in wire and discharge unit, size of grounding conductors and connection requirementsfor grounding electrodes. It is recommended that installation of the outdoor unit be contracted toa professional installer.
Installation537.7.7 Making the ODU Connection at the PTP 500 Series Bridge PIDU PlusThe ODU is connected to the PIDU Plus by means of a concealed RJ45 connector. The RJ45 con-nection has been placed inside the PIDU Plus hinged cover to prevent the user from inadvertentlyplugging other equipment into the ODU RJ45 socket.CAUTION: Plugging other equipment into the ODU RJ45 socket may damage the equipmentdue to the non-standard techniques employed to inject DC power into the 1000BaseT connectionbetween the PIDU Plus and the ODU. Plugging the ODU into other equipment may damage theODU and/or the other equipment.Step 1: Undo the retainingscrew and hinge back the coverStep 2: Plug in the ODU into the PIDUPlus Cable ensuring that it snaps homeStep 3: Replace the cover and secure with the retaining screw
Installation547.7.8 Making the Network Connection at The PIDU Plus – PTP 500 Series BridgeThe Network connection is made by connecting the user’s Network Equipment directly to thePIDU Plus LAN port as shown in Figure 23.Figure 23 Making the Network Con-nection at the PIDU Plus7.7.9 Mounting the PTP 500 Series Bridge PIDU PlusThis step is optional. Motorola recommends that you mount the PIDU Plus on a wall or othersuitable mounting surface. This prevents the unit from being knocked or kicked and can helpmaintain link availability. Ensure that the Recovery switch can be accessed when mounting theunit.Plus to the wall using the lugs providedMake connections as per Section 7.7.8
Installation55CAUTION: The PIDU Plus is not waterproof and should be mounted away from sources ofmoisture. If mounted outdoors, the unit should be mounted in a rain proof enclosure, preferablyventilated.It is also recommended that you fit a drip loop on the PIDU Plus to ODU cable to ensure thatany moisture that runs down the cable into the cabinet or enclosure cannot enter the PIDU Plus.As shown in Figure 24. The network connection and mains cable should be treated in the sameway if there is a risk that they can carry moisture to the PIDU Plus.Figure 24 PTP 500 Series PIDU Plus Drip Loop ConfigurationCAUTION: It is possible for moisture to enter the cable due to damage to the outer protectivelayer. This moisture can track down the inside of the cable, filling up the drip loop and eventuallyfinding its way into the PIDU Plus. To protect against this the outer protective layer of the cablecan be opened up at the bottom of the drip loop to allow this moisture to escape.7.7.10 Powering UpThe PTP 500 Series Bridge is supplied as a pair of matched Master/Slave units. The Master unitcan now be powered up and accessed using the default URL http://169.254.1.2/; the Slave unitcan be accessed using http://169.254.1.1/.Prior to powering up the PTP 500 Series Bridge, a computer with web browsing capabilities shouldbe configured with an IP address of 169.254.n.n and subnet mask of 255.255.0.0 where n is anyvalue between 1 and 254 but excluding 1.1 or 1.2. If the default addresses of the unit 169.254.1.1/2clashes with an address you are already using on your LAN, or you are not sure, you should set upan isolated LAN. As the LAN connection presented at the PIDU Plus has a default configuration
Installation56as a hub/switch (and auto-sensing MDI/MDIX cross over is employed), connection can be madedirectly to the computer using a standard CAT 5 patch cable.Before physical installation takes place the units to be installed should be set up as described inthe Section 8.3.4 "Install Pages". It is recommended that this procedure be carried out on thebench before physical installation commences. Providing it is safe to do so, the installer shouldtake the process to the point where a radio link is established before proceeding to the installationsite.NOTE: It is possible that some units may not be accessed using the above default URL. This isbecause these units may have been previously configured with IP addresses 10.10.10.11 (Master)and 10.10.10.10 (Slave). Therefore, users must use the URL http://10.10.10.10/ and/or URLhttp://10.10.10.11/ to configure the units. Please ensure that a computer with web browsingcapabilities is configured with an IP address of 10.10.10.n, where n is any value between 2 and 254but excluding 10 and 11, to configure these units.7.7.11 Aligning the PTP 500 Series Bridge ODUsThe following is a description of the steps taken to establish a radio link between the two unitsforming the bridge and align the units for the best signal strength.The PTP 500 Series Bridge uses audible tones during installation to assist the installer withalignment. The installer should adjust the alignment of the ODU in both azimuth and elevationuntil highest pitch tone is achieved6. The tones and their meanings are as follows:State Name Tone Description State Description Pitch Indication(Higher pitch =higher power)Free Channel Search Regular beep Executing band scan N/AScanning Slow broken tone Not demodulating thewanted signalRx PowerSynchronized Fast broken tone Demodulating thewanted signalRx PowerRegistered Solid tone Both Master and Slaveunits exchanging Radiolayer MAC managementmessagesRx PowerTable 11 Audio indications from the ODUThe term ‘wanted signal’ refers to that of the peer unit being installed.In each of the states detailed above, the unit should be aligned to give the highest pitch tone. Itshould be noted that if, when in the Synchronized or Registered state, the tone varies wildly, youThe pitch of the alignment tone is proportional to the received power of the wireless signals. The best results are6usually achieved by making small incremental movement in angular alignment.
Installation57may be suffering from interference or a fast fading link. Installing in this situation may not give areliable link. The cause of the problem should be investigated.For the ease of alignment, both Master and Slave units use the install tones in the same way butwith some small behavioral differences. This allows the installer to install the Slave unit first andcarry out the initial alignment with the Master unit if desired. However, due to the behavioraldifferences of Master and Slave units, it is recommended that the Master unit is installed first andthe initial alignment carried out at the Slave unit.Note also that there is a graphical installation screen (Section 8.3.5 "Graphical Install") avail-able using the web interface that displays the state of the link during the alignment process (upgreen,Down, red).The following behavior should be noted:•When first started up and from time to time, the Master unit will carry out a band scan todetermine which channels are not in use. During this time, between 10 and 15 seconds, theMaster unit will not transmit and as a consequence of this neither will the Slave unit. Duringthis time the installation tone on the master unit will drop back to the band scan state, and theSlave unit will drop back to the Scanning state with the pitch of the tone set to the backgroundnoise level. Alignment of the unit should cease during this time.•The master unit can take up to 60 seconds in 0-40km (0-25 miles) mode, 90 seconds in 0-130km(0-81 miles) mode and 120 seconds in 0-200km (0-124 miles) mode to determine the range ofthe link being installed7. The Master unit will remain in the Scanning state until the range ofthe link has been established. The Master unit will only move to the Synchronized state whenthe range of the link has been established.•If, at the end of the ranging period, the Registered state is not achieved due to interferenceor other reasons, the Master unit will retry twice more on the same channel before moving toanother available channel. Should this occur it might take a number of minutes to establish alink in the Registered state.•The Slave unit does not have a ranging process. The slave unit will change to the Synchronizedstate as soon as the wanted signal is demodulated.When the alignment process is complete the installer MUST REMEMBER TO DISARM8BOTHUNITS in the link as described in Section 8.3.4 "Install Pages". This is necessary in order to:•Turn off the audible alignment aid (Section 8.3.4.4 "Disarm")•Enable Adaptive Modulation•Fully enable Advanced Spectrum Management with i-DFS•Clear unwanted installation information from the various systems statistics•Store the link range for fast link acquisition on link drop•Enable higher data ratesIf the unit is operating where mandatory radar avoidance algorithms are implemented the ranging behavior for the7PTP 500 Series Bridge may be affected. The Master has to monitor the initially chosen channel for 60 seconds tomake sure it is clear of radar signals before transmitting. If a radar is detected during any of the installation phasesa further compulsory 60 seconds channel scan will take place as the master unit attempts to locate a new channelthat is free of radar interference.After 24 hours, the units will be disarmed automatically provided that they are armed and that the link is UP.8
Web Page Reference588 Web Page ReferenceThe web user interface has three main sections. The home page presents to the operator a highlevel summary of the PTP 500 Series Bridge point-to-point wireless link. The status page presentsa more detailed set of system parameters describing the performance of the wireless link togetherwith other key system performance metrics. The final section is the system administration section.This section is password protected and allows the system administrator to perform all the day-to-day administrative procedures, e.g. software upgrade and performing configuration changes.The following subsections give a detailed usage guide for all the web user interfaces. The web pagesare best viewed using a screen resolution of at least 1024 x 768 pixels on a PC using MicrosoftInternet Explorer Version 6 or 79.The navigation bar on the left hand side of the web page is used to move between the variousmanagement pages. The currently selected page is always highlighted with a light blue background.The menu is hierarchical. Selecting a menu item which has associated submenu options willautomatically display all sub options. A sample web page with the navigation menu is shown inFigure 25 when the ‘Home’ Link is highlighted as the current page.Figure 25 MenuNavigation BarThe web pages have also been tested with Firefox 2.0.0.12. Other browsers may function correctly but have not9been tested.
Web Page Reference598.1 Home Page – PTP 500 Series BridgeThe home page for the PTP 500 Series Bridge has been designed to display a high level summaryof the status of the wireless link and associated equipment. The home page (Figure 26) normallydisplays four key system attributes:Wireless Link Status: The Wireless Link Status attribute displays the current status of thePTP 500 Series Bridge wireless link. A state of ‘Up’ on a green background indicates that a point-to-point link is established. A state of ‘Down’ on a red background indicates that the wireless linkis not established. If the link is down for an unknown reason the system administrator should firstconsult the status web page for a more detailed summary of up to date system diagnostics.Link Name: The link name attribute is a name and/or handle allocated by the system adminis-trator to aid the identification of the unit, network or building.Figure 26 System Summary PageElapsed Time Indicator: The elapsed time indicator attribute presents the total time in days,hours, minutes and seconds since the last system restart. The system can restart for several reasons,e.g., commanded reboot from the system reboot webpage, or a power cycle of the equipment.System Clock: If SNTP (Simple Network Time Protocol) is enabled, or the clock has beenset, then a system clock attribute is displayed giving the date and time of the last page refresh.Section 8.3.10.8 “SNTP (Simple Network Time Protocol) explains how to enable SNTP andSection 8.3.10.9 explains how to set the clock.8.1.1 Home Page Alarm DisplayThe home page is also used to display all outstanding major system alarms. Whenever systemalarms are asserted, a yellow warning triangle is displayed on web page navigation bar. The warningtriangle will be visible from all web pages. Clicking the warning triangle will cause the web pageto jump back to the system homepage. Figure 27 shows a sample alarm screen.
Web Page Reference60Figure 27 Alarm Warning TriangleThe following system alarms are defined:Region Code: The region code prohibits the wireless unit from operating outside the regulatedlimits. An invalid region code indicates a corrupted license key. Note that a change of state maygenerate an SNMP trap and/or SMTP email alert.Install Status: A non-OK value indicates that signaling was received with the wrong MACaddress. Note that it is very unusual to detect this, because units with misconfigured Target MACAddress will normally fail to establish a wireless link. However, rare circumstances may establisha partial wireless link and detect this situation. NB: A non-OK value on start-up, or a change ofvalue during operation, may generate an SNMP trap and/or SMTP email alert.Install Arm State: This alarm warns when a wireless unit is in installation mode. After instal-lation the wireless unit should be disarmed. This will increase the wireless link’s data-carryingcapacity and stop the installation tone generator. The wireless link is disarmed from the ‘Installa-tion Wizard’ see Section 8.3.4.4 “Disarm”. Note that a change of state may generate an SNMPtrap and/or SMTP email alert.Unit Out Of Calibration: The unit is out of calibration and must be returned to the factoryusing the RMA process for re-calibration. Note that a change of state may generate an SNMPtrap and/or SMTP email alert.Incompatible Region Codes: The PTP 500 Series Bridge uses region codes to comply withlocal regulatory requirements governing the transmission of wireless signals in the 5.8, 5.4 GHzand 2.5 GHz bands. Region codes can only be changed by obtaining a new PTP 500. Note that achange of state may generate an SNMP trap and/or SMTP email alert.
Web Page Reference61Incompatible Master and Slave: A non-zero value indicates that the master and slave ends ofthe wireless link are different hardware products, or have different software versions. Note that itis very unusual to detect this because incompatible units will normally fail to establish a wirelesslink. However, some combinations may establish a partial wireless link and detect this situation.Note that a non-zero value may generate an SNMP trap and/or SMTP email alert.Ethernet Configuration Mismatch Alarm: The detection of Ethernet fragments (runt packets)when the link is in full duplex is an indication of an auto-negotiation or forced configurationmismatch. Note that a change of state may generate an SNMP trap and/or SMTP email alert.No Wireless Channel Available: Spectrum Management was unable to locate a suitable wirelesschannel to operate on. Note that a change of state may generate an SNMP trap and/or SMTPemail alert.SNTP Synchronization Failed: This warning indicates that SNTP has been enabled but thatthe unit is unable to synchronize with the specified SNTP server. Section 8.3.10.8 “SNTP(Simple Network Time Protocol) explains how to configure SNTP. Note that a change of statemay generate an SNMP trap and/or SMTP email alert.Wireless Link Disable Warning: This warning is displayed if the Wireless link has been admin-istratively disabled via the SNMP Interface (see Section 8.3.10 “Remote Management Page”).The Wireless Interface MIB-II ifAdminStatus attribute has been set to DOWN. To enable the Eth-ernet interface, set the ifAdminStatus attribute to UP. Note that a change of state may generatean SNMP trap and/or SMTP email alert.Ethernet Link Disable Warning: This warning is displayed if the Ethernet link has been admin-istratively disabled via the SNMP Interface (see Section 8.3.10 “Remote Management Page”).The Ethernet Interface MIB-II ifAdminStatus attribute has been set to DOWN. To enable the Eth-ernet interface, set the ifAdminStatus attribute to UP. Note that a change of state may generatean SNMP trap and/or SMTP email alert.Ethernet Link Status: Current status of the Ethernet link. If there are any problems with theEthernet interface, this alarm will be asserted. This alarm will most likely be seen if the unit hasno Ethernet cable plugged into its Ethernet socket. Note that a change of state may generate anSNMP trap and/or SMTP email alert.Fiber Link Status: If the fiber link is not OK, there are two possible causes: Either the fiberlink has been installed but disabled (because the license key does not include fiber support), orthe link could not be established even though an optical carrier was detected (due perhaps to abroken TX fiber, or the link is disabled at the fiber link partner). Note that a change of statusmay generate an SNMP trap and/or SMTP email alert.TDD Synchronization Status: Current status of the TDD Synchronization (acquiring synchro-nization, no timing reference and timing system not connected). Note that a change of state maygenerate an SNMP trap and/or SMTP email alert.8.2 Systems Status PageThe status page has been designed to give the system administrator a detailed view of the operationof the 500 Series Bridge from both the wireless and network perspectives.
Web Page Reference62The page is subdivided into three main categories Equipment, Wireless and Ethernet/Internet. The‘Equipment’ section contains the unit’s inventory and identification information. The ‘Wireless’section presents the key wireless metrics, which are displayed as a series of measurements. The‘Ethernet/Internet’ section describes the unit’s network identity and connectivity.The status page can be configured to refresh itself at an operator defined rate (if the user is loggedin as system administrator). The refresh period defaults to 3600 seconds and can easily be changedto refresh at any period between 2 seconds and 3600 seconds. Pressing the ‘Update Page RefreshPeriod’ button causes a new page refresh period to be adopted by the system. The page refreshmechanism uses a HTML Meta refresh command. Therefore the refresh is always initiated by thelocal browser and not by the 500 Series Bridge at this interval.The two PTP 500 Series bridges units are arranged in a master and slave relationship. The rolesof the units in this relationship are displayed in the page title. The master unit will always havethe title ‘- Master’, and the slave will always have ‘- Slave’ appended to the ‘Systems Status’ pagetitle.Figure 28 Status PageThe following section details all the attributes displayed on the status page:Link Name: The link name is allocated by the system administrator and is used to identify theequipment on the network. The link name attribute is limited to a maximum size of 63 ASCIIcharacters.Link Location: The link location is allocated by the system administrator and can be used asa generic scratch pad to describe the location of the equipment or any other equipment relatednotes. The link location attribute is limited to a maximum size of 63 ASCII characters.Software Version: The attribute describes the version of software installed on the equipment.The format of the attributes is FFSSS-XX-YY where FF is the frequency variant (2.5, 5.4 or 5.8GHz), SSS is the System Release, XX is the major release version and YY is the minor releaseversion.
Web Page Reference63Hardware Version: The hardware version attribute contains all the combined hardware versioninformation. The attribute is formatted as DXX-RYY-Z where DXX contain the version of thedigital card, RYY contains the version of the RF (radio frequency) card and Z describes the antennatype which can be I (integrated) or C (connectorized).Region Code: The region code is used by the system to constrain the wireless to operate withinregulatory regime of the particular country. The region code is encoded in the product license key.If the operator wishes to change region code, a new license key must be obtained from Motorolaor the local point-to-point distributor / system integrator.Elapsed Time Indicator: The elapsed time indicator attribute presents the total time in years,days, hours, minutes and seconds since the last system restart. The system can restart for sev-eral reasons, e.g. commanded reboot from the system reboot web page, or a power cycle of theequipment.Ethernet Link Status: Current status of the Ethernet link. A state of ‘Up’ with a green back-ground indicates that an Ethernet link is established. A state of ‘Down’ with a red backgroundindicates that the Ethernet link is not established.Ethernet Speed and Duplex: The negotiated speed and duplex setting of the Ethernet interface.The speed setting is specified in Mbps. Full Duplex data transmission means that data can betransmitted in both directions on a signal carrier at the same time. For example, on a local areanetwork with a technology that has full duplex transmission; one workstation can be sending dataon the line while another workstation is receiving data. Half Duplex data transmission meansthat data can be transmitted in both directions on a signal carrier, but not at the same time.For example, on a local area network using a technology that has half duplex transmission, oneworkstation can send data on the line and then immediately receive data on the line from the samedirection in which data was just transmitted.Remote IP Address: Hyperlink to the other side of the Link. The IP address of the peer link isdisplayed if the Link is UP, otherwise “unavailable” is displayed.Refresh Page Period: The Status page refreshes automatically according to the setting enteredhere (in seconds). This attribute is only displayed when the user is logged on as System Adminis-trator.Wireless Link Status: As the attribute name suggests it displays the current status of the wirelesslink. A state of ‘Up’ on a green background indicates that a point-to-point link is established. Astate of ‘Down’ on a red background indicates that the wireless link is not established.Maximum Transmit Power: The maximum transmit power that the local wireless unit is per-mitted to use to sustain a link.Remote Maximum Transmit Power: The maximum transmit power that the remote wirelessunit is permitted to use to sustain a link.Transmit Power: Transmit power histogram10 is expressed in dBm and presented as: max, mean,min, and latest. The max, min and latest are true instantaneous measurements; the mean is themean of a set of one second means.An histogram is calculated over a one hour period. If the equipment has been running for less than one hour then10the histogram is calculated over the current elapsed time. The data used to compute the histogram statistics canbe downloaded in an ASCII comma separated value (CSV) format via the diagnostics CSV Download page, seeSection 8.3.11.2 “Diagnostics Download”.
Web Page Reference64Receive Power: Receive power histogram is expressed in dBm and presented as: max, mean,min, and latest. The max, min and latest are true instantaneous measurements; the mean is themean of a set of one second means. See footnote 10 “histograms”.Vector Error: The vector error measurement compares the received signal’s In phase / Quad-rature (IQ) modulation characteristics to an ideal signal to determine the composite error vectormagnitude. The results are stored in an histogram and expressed in dB and presented as: max,mean, min and latest. The max, min and latest are true instantaneous measurements; the meanis the mean of a set of one second means. The expected range for Vector Error would be approx-imately -2dB (NLOS link operating at sensitivity limit on BPSK 0.67) to -33dB (short LOS linkrunning 256 QAM 0.83). See footnote 10 “histograms”.Link Loss: The link loss is the total attenuation of the wireless signal between the two point-to-point units. See footnote 10 “histograms”.The link loss calculation presented below:Pl=PT−PR+gT+gR(4)WherePl= Link Loss dBPT= Transmit power of the remote wireless unit dBmPR= Received signal power at the local unit dBmgt,gr= Antenna gain at the remote and local units respectively11 dBiEquation - Link LossTransmit Data Rate: The data rate in the transmit direction, expressed in Mbps and presentedas: max, mean, min, and latest in an histogram format. The max, min and latest are trueinstantaneous measurements; the mean is the mean of a set of one second means.See footnote 10 “histograms”. Expected data rates can be found in Section 14 “Data RateCalculations”.Receive Data Rate: The data rate in the receive direction, expressed in Mbps and presented as:max, mean, min, and latest in an histogram format. The max, min and latest are true instantaneousmeasurements; the mean is the mean of a set of one second means.See footnote 10 “histograms”. Expected data rates can be found in Section 14 “Data RateCalculations”.Link Capacity: The maximum aggregate data rate capacity available for user traffic, assumingthe units have been connected using Gigabit Ethernet. The link capacity is variable and dependsof the prevailing wireless conditions as well as the distance (range) between the two wireless units.Transmit Modulation Mode: The modulation mode currently being used on the transmitchannel. List of all the modulation modes can be found in Section 14 where data rate calculationsplots are given for each available modulation mode.The antenna gain of the 500 Series bridge (23.5 dBi) is used unless one or both of the units is a Connectorized11version.
Web Page Reference65Receive Modulation Mode: The modulation mode currently being used on the receive channel.List of all the modulation modes can be found in Section 14 where data rate calculations plotsare given for each available modulation mode.Receive Modulation Mode Detail: This supplies the user with information regarding thereceive modulation mode in use. Possible values are:•Running at maximum receive mode•Running at user-configured Max Modulation Mode•Restricted due to byte errors on the wireless link or local Ethernet Tx Fifo Drops•Restricted because a DFS channel change is in progress•Restricted due to telecoms acquisition mode•Restricted due to the low Ethernet link speed•Limited by the wireless conditionsRange: The range12 between the 500 Series bridge ODUs.8.3 System Administration PagesThe following menu options are available for the system administrator and can be password pro-tected. Figure 29 shows the system administration login page. By default a system administratorpassword is not set. Simply click the login button to access the system administration features.Figure 29 System Administration Login PageOnce the password has been set using the ‘Change Password’ menu item the system administrationpages will only be available after the user has entered the correct password.The features that are only available to the system administrator are:•Configuration•Statistics•The Installation Wizard•Software UpgradeThe PTP 500 Series Bridge displays range in km by default, if the user would prefer to display range using Miles the12‘Distance Units’ attribute should be set to imperial, see the “Properties” web page Section 8.3.14 “Properties”.
Web Page Reference66•Spectrum Management including DFS•Remote management•Diagnostics Plotter•Password Management•License Key Management•Properties•System Reboot8.3.1 System ConfigurationThe configuration of the 500 Series Bridge is organized into three sections:•General configuration•LAN configuration•Telecoms Configuration•Save and RestoreThe general configuration allows modification of high level administrative (descriptive) attributesand high level wireless configuration.The LAN configuration sub menu allows the system administrator to modify the Ethernet and IPconfiguration of the 500 Series Bridge.The telecoms submenu displays the current status of the telecoms interface and allows the config-uration of interface loopbacks.The save and restore submenu allows the system administrator to backup and restore the bridgeconfiguration. It is recommended after a unit has been successfully installed; a copy of the activeconfiguration is taken and archived by the system administrator.8.3.1.1 General Configuration PageThe general configuration page (Figure 30) is used by the system administrator to configurethe 500 Series Bridge’s high level administrative (descriptive) attributes and high level wirelessconfiguration.
Web Page Reference67Figure 30 System Configuration PageWhile the majority of the system configuration is entered during installation and should neverrequire changing, this page offers the system administrator the ability to change the basic systemparameters for both the wireless and Ethernet components.Link Name: User defined identity for the unit (max 63 characters).Link Location: Can be used as a generic scratch pad to describe the location of the equipment.Master Slave Mode and Link Mode Optimization current settings are displayed and can bemodified using the Installation Wizard pages. See Section 8.3.4 “Install Pages”Max Receive Modulation Mode: This is the maximum mode the unit will use as its adaptivemodulation. By default the Max Receive Modulation Mode is the highest mode available.For minimum error rates on TDM links the user should set the maximum modulation mode to64QAM 0.75 at both ends of the link.Ethernet Capped Max Wireless Speed: When enabled this option will cap the wireless speedto a mode that the connected Ethernet connection can sustain.Maximum Transmit Power: This specifies the maximum transmit power in dBm of the system.It is country dependent and although the user can change this in 1dB steps, it will be limited tothat country’s regulations13.In the UK there is a legal requirement to provide a minimum of 19dB of transmit power control range. When the13equipment is operating with a UK License Key, an additional facility is provided on the configuration page thatallows the transmitted power to be reduced by 19dB compared to the maximum allowed with a simple single stepcontrol.
Web Page Reference68Why Reduce Transmit Power?If the link losses are low and the link data rate and availability targets are being easily achieved,the transmitted power level may be reduced with a consequent benefit to other users of the band,e.g. fixed satellite links.8.3.1.2 LAN Configuration PageThe LAN configuration page (Figure 31) is used by the system administrator to configure the500 Series Bridge’s LAN interface.Figure 31 LAN Configuration PageIP Address: Internet protocol (IP) address. This address is used by the family of Internetprotocols to uniquely identify this unit on a network.Subnet Mask: A subnet allows the flow of network traffic between hosts to be segregated basedon a network configuration.Gateway IP Address: The IP address of a computer / router on the current network that actsas a gateway.
Web Page Reference69VLAN High Priority Traffic Threshold: All packets with an 802.1P priority tag greater thanor equal to the indicated value will be treated as a high priority packet for transmission over thewireless link.Use VLAN For Management Interfaces: This controls whether the management interfaces(WWW/SNMP/SMTP/SNTP) use 802.1Q VLAN tags or not. See Section 8.3.1.3 “LAN Con-figuration Page - Use VLAN For Management Interface”.Ethernet Auto Negotiation: This enables the Ethernet configuration to be forced rather thanauto negotiated.Caution:The configuration should only be forced if you are having problems with autonegotiation. You must ensure that you configure both this unit and the Ethernet portto which it is connected identically. If you force a fixed Ethernet Configuration onthe 500 Series bridge then you MUST also force the same fixed configuration onthe equipment to which it is connected. If you fail to force the configuration of theconnected equipment, its automatic configuration mechanisms will normally cause aduplex mismatch, and you will receive greatly reduced throughput!When Ethernet Auto Negotiation is Disabled the format of the LAN configuration page will changesee Section 8.3.1.4 “LAN Configuration Page – Manual Ethernet Configuration”.Auto Neg Advertisement: This controls the rates that the auto negotiation mechanism will ad-vertise as available. Warning: Over the air throughput will be capped to the rate of the Ethernetinterface at the receiving end of the link.Ethernet Auto Mdix: This enables/disables the Auto Medium Dependent Interface (MDI)/MediumDependent Interface Crossover (MDIX) capability. Default is “Enabled”.Drop Ethernet Link On Wireless Link Down: When this option is enabled the Ethernetlink is momentarily dropped when the wireless link goes down. This feature is used to indicate tothe connected network equipment that this Ethernet link is no longer available, thus causing STP(Spanning Tree Protocol) to re-route packets through an alternate link.Local Packet Filtering: When Local Packet Filtering is “Enabled”, the bridge learns the sourceMAC addresses of devices transmitting Ethernet packets on the local Ethernet network, and onlybridges packets to the remote unit if the destination MAC address has not been learned as a’local’ device. When Local Packet Filtering is ‘Disabled’ the bridge does not learn the source MACaddresses of devices transmitting Ethernet packets on the local Ethernet network, and bridgesALL Ethernet packets received to the remote unit. Local Packet Filtering should be disabled whenexternal Ethernet switching hardware or a router is present. The default setting for Local PacketFiltering is disabled.All of the above attributes are non-volatile, once set they will be used by the unit even after a poweron reboot. A number of attributes, such as IP Address, Subnet Mask and Gateway IP Address andVLAN settings will require a reboot before they are used. If any of these attributes are changed areboot screen appears asking the user to verify the reboot (Figure 32 or Figure 33).

Web Page Reference738.3.1.5 Save and Restore Configuration FileThe save and restore feature of a PTP 500 Series Bridge allows the system administrator tobackup the operation configuration of the wireless unit. It is recommended that this facility isused immediately after a successful PTP 500 Series Bridge installation or prior to any softwareupgrade. In the unlikely event that a unit has to be replaced in the field, the replacement unit canbe reconfigured by simply playing back the saved configuration file.To save the configuration file click on the ‘Save Configuration File’ button (Figure 36) and savethe configuration file (.cfg) to the hard drive of your computer14 15.Figure 36 Save and Restore Configuration PageThere is a feature of Internet Explorer (all versions) that will always look at the content of any downloadable file14as make an assessment whether to treat the file as an ASCII or binary file. Unfortunately the configuration file isalways treated as ASCII and the browser attempts to display it instead of downloading it. Firefox (all versions)makes no such assumptions.The configuration file format is MAC-mm-mm-mm_IP-iii-iii-iii-iii.cfg where mm and iii are the lower 3 bytes of the15MAC address and the unit IP address respectively.
Web Page Reference74Figure 37 Save Configuration File Screen
Web Page Reference75The configuration file is encoded using an ASCII encoding scheme. An example is show inFigure 38.Figure 38 PTP 500 Example Configuration FileCAUTION: The configuration file is currently restricted to a single software version and canonly be restored into a wireless unit operating the software version indicated in the configurationfile header.The configuration file can also be used when swapping out a faulty wireless unit. If one of thewireless units is replaced on a wireless link a configuration file captured from the faulty unit canbe uploaded into the new unit to speed up replacement. It should be noted that when placinga configuration file into a wireless unit with a different MAC Address the license key will not berestored and may need to be entered. This can be obtained either from the Quick Start Guidesupplied with the replacement wireless unit or directly from Motorola. Note that the target MACaddress at the other end needs to be changed to ensure that it is using the MAC address of thereplaced unit.The restoration of configuration files can be performed using the Restore configuration tool. Usingthe browser button to locate the configuration file you wish to restore then click the ‘RestoreConfiguration File and Reboot’ button (Figure 39). The user will then be prompted to confirmthe action (Figure 40)

There follows a description of the install pagesalong with their use during the installation configuration process. The actual installation processis described in Section 8.3.4.1 “Manually Configuring the Wireless Units”.All wireless links are shipped as paired units. They are pre-configured at the factory so thatthey can be installed without the user supplying any configuration. Each wireless link is shippedwith a quick start guide. Attached to the quick start guide is a summary of the pre-configuredconfiguration data. Table 12 shows a sample link configuration. The values highlighted have beencommitted to the wireless unit’s non-volatile storage.

If you wish to install awireless link with a range of >40 Km (>25 miles) and <200 Km (<124 miles) or <5Km(<3miles) you must follow the steps in Section 8.3.4.1 “Manually Configuring The Wireless Units”.The factory default configuration is set to Region 26. Region 26 allows the 500 Series bridge amaximum transmit power of 25 dBm. If the local regulatory regime limits the maximum transmitpower (EIRP) to less than 25 dBm you should obtain a new license key containing the correctregion code from your local distributor or direct from Motorola. Alternatively in the short term,you should reduce the maximum transmit power by following the procedures in Section 8.3.4.1“Manually Configuring The Wireless Units”.8.3.4.1 Manually Configuring The Wireless UnitsIf the installer / system administrator wishes, they may modify the default installation configu-ration. If only the IP addresses (network configuration) are incorrect it is recommended that thevalues are changed via the configuration menu (Section 8.3.1.2 “LAN Configuration Page”). If
Web Page Reference84any other parameters require modification then it is recommended that the system administratoruse the Installation Wizard.A detailed description of the Installation Wizard follows: The 500 Series bridge operational softwarerequires a license key to enable the wireless bridging capability and programs region code specificparameters in to the unit.Figure 43 License Key Data EntryA license key is programmed into each unit during production and can be found written on theConfiguration Data Summary Label which is attached to the Quick Install Guide. If subsequentlythe license key has been mislaid, replacement keys can be applied for online or via your distributor.If a valid license key is not detected in the unit’s non-volatile memory then the user is promptedto enter a valid key. It should be noted that 500 Series bridge units are shipped as link pairs and,as such, valid license keys are entered during the production process. To enter a license key simplytype or paste the license key into the data entry box (Figure 43) and click the ‘validate licensekey’ button.8.3.4.2 Internet Protocol ConfigurationStep 1 of the installation wizard requires the installer to enter the Internet Protocol (IP) configu-ration.
Web Page Reference85Figure 44 Installation Wizard Internet Protocol ConfigurationIP Address:Internet protocol (IP) address. This address is used by the family of Internet protocolsto uniquely identify this unit on a network.Subnet Mask:A subnet allows the flow of network traffic between hosts to be segregated based ona network configuration. By organizing hosts into logical groups, subnetting can improve networksecurity and performance. Gateway IP Address: The IP address of a computer / router on thecurrent network that acts as a gateway. A gateway acts as an entrance / exit to packets from / toother networks.Use VLAN Management Interface:Controls whether the management interfaces (HTTP/SNMP/SMTP/SNTP) use a VLAN. Selecting this option presents the user with extra fields in which toenter the Management VLAN ID, Priority and whether to validate the VLAN ID. If the usermodifies this control, a warning dialog is displayed see Figure 45.Telecoms Interface This allows the activation of the 500 Series bridge telecoms interface. If theselection options are disabled, T1 or E1 note mixed T1/E1 configurations are not permitted.
Web Page Reference86Figure 45 VLAN WarningOnce complete, click the ‘Submit Internet Protocol Configuration’ button or the ‘Next’ link.8.3.4.3 Wireless ConfigurationStep 2 of the installation wizard requires the installer to enter the wireless configuration parameters.Figure 46 5.8 GHz and 5.4 GHz Variants -Installation Wizard Wireless Configuration
Web Page Reference87Target MAC Address:It is the MAC Address of the peer unit that will be at the other end ofthe wireless link. This is used by the system to ensure the unit establishes a wireless link to thecorrect peer.The MAC Address can be found embedded within the serial number of the unit. The last sixcharacters of the serial number are the last three bytes of the unit’s MAC address. (Note: A PTP500 Series system is shipped as a pair of units with pre-loaded correct MAC addresses. TargetMAC addresses will only need to be entered if an existing unit has to be replaced in the field orthe units configuration has been erased).Master Slave Mode:At this point it is necessary to decide which end will designate a Master.The Master unit is the controlling unit with respect to the point-to-point link and its maintenance.The master transmits until the link is made, while the Slave listens for its peer and only transmitswhen the peer has been identified.Link Mode Optimization:Optimizes the link behavior according to the type of traffic that willbe bridged. There are two modes to choose from: IP and TDM.In IP Mode, the PTP 500 product runs an Adaptive TDD scheme. Basically an unloaded linkruns 10:10 mode (10 OFDM bursts alternately in each direction). A sustained traffic load in onedirection for example may cause a threshold to be reached where the TDD mode automaticallyadapts to say 20:10. If the load continues to increase, then the TDD structure may adapt evenfurther through 30:10 to 40:10. This is a state of maximum link asymmetry (40 OFDM burstsin one direction compared with 10 in the other). If the load increases in BOTH directions, thenthe TDD structure can adapt from 10:10, through 20:20, 30:30 and finally 40:40. This is a stateof maximum aggregate throughput. So if three out of these combinations are considered; 10:10,40:10 and 40:40 they would give the following characteristics:10:10: equal performance in each direction, lowest aggregate throughput and lowest Latency.40:10: achieves maximum one way throughput performance, to the detriment of both latency andthroughput in the opposite direction.40:40: Maximum link aggregate rate, balanced performance in each direction, higher latency.Note that there is an engineering trade-off between the flexibility of ATDD and Latency as follows:When the TDD structure changes, there will be a short term impact on Latency for a few Frames.This would not affect the steady state long term average latency, but could be recorded as aMaximum latency. This affect may be amplified for short Latency tests or if the traffic loadingis oscillating either side of a boundary condition. As the TDD burst length increases, Traffic ineach direction will have to wait longer before a Transmit window is available, but more data canbe sent during the burst. There is an impact on latency but it varies depending upon installationrange, Frame size and modulation mode.In TDM mode, two major differences in link behaviour occur compared with IP mode. First theTDD structure is fixed symmetrically. Either 10:10, 20:20, 30:30 or 40:40 based upon the installedrange.Secondly, the point at which a modulation mode changes for given RF conditions is more conser-vative. In practice, this means that the link will typically stay in a lower modulation mode, butwith increased tolerance to RF variability.
Web Page Reference88Depending upon the link characteristic that the customer requires, this may very well be the bestchoice. It increases consistency of link performance and equality in each direction as a trade-offagainst maximum throughput.Tx Max Power:This attribute controls the maximum transmit power the unit is permitted touse when installing and executing the wireless link. The maximum setting for a particular regionor country is controlled by the License Key.Platform Variant:Chooses between an integrated unit or a connectorized unit that requires anexternal antenna.Channel Bandwidth:Users can choose a variable channel bandwidth for the available spectrum.Value is 15 MHz.Spectrum Management Control:Is used to configure the PTP 500 Series Bridge’s SpectrumManagement features, see Section 8.3.7 “Spectrum Management” for more details. i-DFS is theabbreviation for intelligent Dynamic Frequency Selection. This feature continually monitors thespectrum looking for the channel with the lowest level of on channel and co-channel interference.Fixed frequency mode allows the installer to fix transmit and receive frequencies on the units. Thefrequencies may be configured symmetrically or asymmetrically.Lower Center Frequency:The software for the PTP 500 Series Bridge allows a user to optionallyadjust the channel center frequencies. Changing the Lower Center Frequency attribute causes allchannel center frequencies to be offset. It effectively slides the channelization up or down. SeeSections Section 5.5 “5.4 GHz Specific Frequency Planning Considerations” and Section 5.6“5.8 GHz Specific Frequency Planning Considerations” depending on the frequency variant.Warning: The lower center frequency attribute must be configured to the same value for boththe master and slave. Failure to do so will cause the wireless link to fail reestablishment. The onlyway to recover from this situation is to modify the Lower Center Frequency attribute so that theyare identical on both the master and slave unit.Fixed Transmit Frequency, Fixed Receive Frequency:The software for the PTP 500 Se-ries Bridge allows a user to optionally fix the Transmit and the Receive frequencies for a wirelesslink. The settings must be compatible at each end of the link. Once configured the spectrummanagement software will not attempt to move the wireless link to a channel with lower co oradjacent channel interference. Therefore this mode of operation is only recommended for deploy-ments where the installer has a good understanding of the prevailing interference environment.Figure 47 shows a sample fixed frequency configuration for a 30 MHz channel bandwidth. In theexample the lower center frequency is set to its default values and the Fixed Transmit Frequencyis set to 5735 MHz and the Fixed Receive Frequency is set to 5735 MHz. Care must be takenwhen configuring the Fixed Transmit and Receive Frequencies to ensure that both frequencies areon the same 5 MHz channel raster as the Lower Center Frequency. For example both the FixedTransmit and Receive Frequencies must be a multiple of 5 MHz from the Lower Center Frequency(5740 = 5735 + 5 MHz) and (5745 = 5735 + 5 MHz x 2). Please note that there is a raster thatlimits the selection of the Rx frequency based upon the setting of the Tx frequency, and that thelist of options presented in the fixed Tx frequency box is limited to that raster.

If the installer wishes to modify the installation configuration then the ‘Back’ linkcan be used to access the installation wizard steps described above.After disarming the wireless link the user is presented with one of two possible configurationpages, see Figure 52 and Figure 51. The screen presents hyperlinks to the main configurationand spectrum management pages.Figure 51 Optional Post Disarm Configuration 2Figure 52 Optional Post Disarm Configuration 1After installation the system administrator may wish to modify the wireless units descriptive con-figuration (link name and link location). In addition the system administrator may wish to changethe spectrum management configuration of the wireless unit, or look at the analysis of the 5.8 GHzspectrum to see if the automatic channel selection is appropriate for the system administrator’snetwork. It is also recommended that a backup copy of the wireless units configuration is taken.Hyperlinks are provided on the post disarm page for ease of use.The installation process is completed when both ends of the link are ‘disarmed’.17
Web Page Reference948.3.5 Graphical InstallTo aid the installation of wireless links two graphical installation aids have been introduced in this500 Series system version.•A PDA installation screen•A larger installation screen available from the main HTTP management interface.The design of the installation screen has been deliberately kept simple and uncluttered. An exampleof the installation screen is shown in Figure 53. Both the PDA and the large format installationscreen have the same content and only differ in size. The PDA installation screen is 232 by 220pixels to be compatible with the typical size of a PDA screen.Figure 53 Graphical Installation ScreenThe screen displays the receive power over the last three minutes. This will allow the installerto slowly sweep the antenna during installation and monitor the variation in signal strength withangular position. The screen automatically refreshes every three seconds.The screen also displays the current state of the wireless link in two ways. First, the actual stateof the wireless link is written in the top left corner of the screen. The instantaneous receive powerbar also encodes the state of the wireless link using green to signify that the wireless link is up andred for all other states.For the more technically aware, the installation metric is simply the instantaneous receive powerin dBm + 100.The PDA installation tool is accessed via a hidden URL http://<ip-address>/pda.cgi. It shouldbe noted that this link is only available after the user has logged in as system administrator.The large screen version of the graphical user interface is available as a submenu option of theinstallation wizard.
Web Page Reference958.3.6 Software UpgradeThe 500 Series system has two software image banks; one is a fixed image which is stored inprotected non-volatile memory and cannot be modified by the user. The second bank is used bythe system administrator to upgrade the firmware when necessary. Figure 54 shows the mainsoftware upgrade web page.Figure 54 Software UpgradeThe ‘Fixed’ or ‘Recovery’ image is used by the System Administrator to:•Reset Ethernet configuration to default settings•Erase Configuration•Upgrade softwareFor a full description of the Recovery image see Section 9 “Recovery Mode”.The software upgrade pages are used to update a unit’s operational software. The software imageto be uploaded should be downloaded to local storage from the Motorola web site. The softwareimage is delivered by Motorola as a compressed zip file. Once the zip file has been downloaded,the user should extract the PTP 500 Series Software image, identifiable by its ‘.dld’ file extension.The first step (Figure 54) is to use the “Browse” button to locate the software image previouslydownloaded to local storage from the Motorola web site. Once the image is located, the user shouldpress the “Upload image to wireless unit” button to start the software upgrade process18.During the software upgrade process, ensure that the remote end is upgraded first using the wireless connection and18then the local end can be upgraded.
Web Page Reference96The software image will now be uploaded to the unit. This upload should only take a few seconds.Once complete the image is verified and validated to ensure that no errors occurred during transferand that the image is valid to run on the current platform. If there are any problems a warningscreen will appear.The unit being upgraded will now display information about the build it currently has stored inthe image bank and the one that’s just been uploaded. If the image is not the right one, the userhas the option to go back and reload a new image. (See Figure 55)Figure 55 Software Upgrade Image CheckThe user should ensure that the correct image is shown before pressing the “Program SoftwareImage into Non-Volatile Memory” button. Once this button has been pressed the image is storedinto non-volatile memory, this process can take up to 60 seconds and must not be interrupted.If the upgrade process is interrupted during the erasure of the image bank, or during the repro-gramming of the image bank, the image bank will be left in a corrupt state. If this occurs thesoftware must be reloaded. All software images that are stored in non-volatile memory are pro-tected via the use of CRCs. If the software detects an invalid CRC the image bank is marked as‘corrupt’ and the 500 Series bridge boot code will boot the fixed software image. If this occurs theuser must attempt to reload the correct version of software.During the write process the progress of the upgrade is displayed on the progress tracking page(Figure 56). The upgrade process should not be interrupted. Interruption of this process canresult in a corrupt main software image, which will result in the recovery image been booted atthe next reset cycle.
Web Page Reference97Figure 56 Software Download Progress IndicatorFigure 57 Software Upgrade CompleteWhen the software image has been written to non-volatile memory Figure 57 will be displayedshowing the status of the software upload.Reboot the unit by clicking the “Reboot Wireless Unit” button. You will be asked to confirm thisaction as shown in Figure 58.Figure 58 Reboot Confirmation Pop UpThis will reboot the unit, taking up to 120 seconds. During this time you will not be able tocommunicate with the unit.
Web Page Reference98If you cannot communicate with the unit after 120 seconds, this could indicate a problem with thememory update process. Under these circumstances the user should enter “Recovery Mode”, seeSection 9 “Recovery Mode”.After the reboot the user should check that the required software image is loaded and running.NOTE: Please ensure that you are upgrading the correct units. Units cannot be downgraded..8.3.7 Spectrum ManagementSpectrum Management Selection is the PTP 500 Series Bridge feature that monitors the availablewireless spectrum and directs both ends of the wireless link to operate on a channel with a minimumlevel of co-channel and adjacent channel interference.8.3.7.1 Wireless ChannelsThe PTP 500 Series Bridge operates using a set of predefined overlapping channels. There are adifferent number of channels, depending on the raster mode selected. Each channel occupies 15MHz of wireless spectrum and is offset in center frequency from its neighboring channel by 5 MHz.It is important to note that adjacent channels on the Spectrum management display have a 5 MHzoverlap to the adjacent channel.The default channelization can be modified by varying the lower center frequency attribute inthe installation wizard - see Section 8.3.4.3 “Wireless Configuration”. See Section 5 “GeneralConsiderations” for more detail.8.3.7.2 Spectrum Management MeasurementsThe 500 Series Bridge performs two mean signal measurements per TDD cycle, per channel. Thismean measurement represents the mean received signal power for the 40 microseconds measurementperiod.The Spectrum Management algorithm collects measurements equally from all channels.This process is called the Channel Availability Check (hereafter referred to by the acronym CAC).The CAC uses a round-robin channel selection process to collect an equal amount of measurementsfrom each channel. It is important to note that the CAC measurement process is not altered bythe channel barring process. Measurements are still collected for all channels irrespective of thenumber of barred channels.8.3.7.3 Measurement AnalysisSpectrum Management uses statistical analysis to process the received peak and mean measure-ment. The statistical analysis is based on a fixed, one minute, measurement quantization period.Spectrum Management collects data for the specified quantization period and only at the end ofthe period is the statistical analysis performed.The analysis produces three key metrics for each channel:
Web Page Reference99•Peak of Means•99.9% Percentile of the Means•Mean of MeansPeak of Means:is the largest mean interference measurement encountered during the quantizationperiod. The peak of means is similar to the peak of peaks and is useful for detecting slightly longerduration spikes in the interference environment. 99.9% Percentile of the Means is the value ofmean interference measurement which 99.9% of all mean measurements fall below, during thequantization period. The 99.9% percentile metric is useful for detecting short duration repetitiveinterference that by its very nature has a minimal effect of the mean of means.Mean of Means:is the arithmetic mean19 of the measured means during a quantization period.The mean of means is a coarse measure of signal interference and gives an indication of theaverage interference level measured during the quantization period. The metric is not very goodat predicting intermittent interference and is included to show the spread between the mean ofmeans, the 99.9% percentile and the peak of means.Important Note: Spectrum Management uses the 99.9% percentile as the prime interferencemeasurement. All subsequent references to interference level refer to this percentile measurement.The display of statistical measurement on the spectrum management page always shows a statisticalsummary of all channel measurement. The statistical summary is controlled by the StatisticsWindow attribute. This attribute defaults to a value of twenty minutes, which means that themean and percentile values displayed for each channel are calculated over the 20 minute period.All channel decisions are made using the values computed over the statistics window period.8.3.7.4 The Spectrum Management Master / Slave RelationshipThe Spectrum Management operates in a master / slave relationship. The master is assumed to bethe link master configured during installation. All Spectrum Management configuration changesMUST be performed from the master. To enforce this, the Spectrum Management web page hasa different appearance depending if you are viewing the data from the master or slave.All configuration changes are applied at the master only. These changes are then messaged fromthe master to the slave. Any Spectrum Management configuration messages received at the slaveare stored in non-volatile memory. This enables both master and slave to keep identical copies ofSpectrum Management configuration data in their non-volatile memories. It is therefore possibleto swap master and slave roles on an active Point-to-Point link without modifying SpectrumManagement configuration.The arithmetic mean is the true power mean and not the mean of the values expressed in dBm.19

It shouldbe noted that the key configuration attributes are not available on the slave web page.8.3.7.5 Spectrum Management ConfigurationThe following section describes the user modifiable configuration accessible from the SpectrumManagement webpage. It is recommended that the default values are maintained. If the userbelieves that the performance of the Spectrum Management algorithm requires some modificationsthis should only be done after consulting your Motorola Point-to-Point distributor or one of thesystem field support engineers.Page Refresh Period: The page refreshes automatically according to the setting entered here(in seconds).
Web Page Reference102Hopping Margin:Spectrum Management uses this margin when making a channel hop decision.The target channel has to have an interference level 3 dB (default) better than the current activechannel.Hopping Period (not configurable):The Spectrum Management algorithm evaluates the met-rics every ‘Hopping Period’ seconds (180 seconds by default) looking for a channel with lower levelsof interference. If a better channel is located, Spectrum Management performs an automated chan-nel hop. If SNMP or SMTP alerts are enabled an SNMP TRAP or an email alert is sent warningthe system administrator of the channel change.Hopping Counter:is used to record the number of channel hops. The number in the “(+)”brackets indicates the number of channel changes since the last screen refresh.Interference Threshold:Spectrum Management uses the interference threshold to perform in-stantaneous channel hops. If the measured interference on a channel exceeds the specified threshold,then iDFS will instruct the wireless to immediately move to a better channel. If a better channelcannot be found the 500 Series Bridge will continue to use the current active channel. (Default -85dBm)Asymmetric DFS:The default configuration of symmetric operation constrains the link to op-erate symmetrically, using the same transmit and receive channels. When in symmetric mode theslave unit will always follow the master. If the master moves to a new channel the slave will hopto the same channel. When the Point-to-Point link is configured as an asymmetric link both themaster and slave are free to select the best channel from their own set of local interference metrics.Channel Bandwidth (not configurable):shows the value of the variable channel bandwidthselected.8.3.7.6 Barring ChannelsChannels can only be barred / unbarred by the system administrator from the master SpectrumManagement web page. The barring / unbarring operations are disabled on the slave web page. Ifan attempt to bar / unbar a channel is made at the slave, a warning dialog is generated.Barring/Unbarring of channels is performed by clicking the appropriate channel on the local orpeer channel spectrum plots on the master web page. Each bar / unbar attempt will be proceededby a confirmation dialog. It should be noted that the channel bar will take effect immediately andis not related to the measurement quantization period.8.3.7.7 Master and Slave Channel Spectrum GraphicsSpectrum Management presents its computed statistical measurements in a graphical display onboth the master and slave Spectrum Management web page.
Web Page Reference103Figure 61 Example Spectrum Management GraphicThe X-axis shows a stylized view of the selectable wireless channels. It is important to note thatadjacent channels on the display have a 10 MHz overlap. The display separates the display ofchannels to help the clarity of the resultant display. The axis is labeled using the channel centerfrequencies in MHz.The Y-axis shows the interference power levels from -100 to -40 dBm.The active channel (channel 5 in Figure 61) is always marked using hatched green and white lines.The width of the hatching is directly proportional the channel bandwidth spectral occupancy ofthe channel.The individual channel metrics are displayed using a colored bar and an ‘I’ bar.The colored bar represents the following channel state:
Web Page Reference104Green Active The channel is currently in use, hosting the Point-to-Point wirelesslink.Orange Interference The channel has interference above the intererence thresholdBlue Available The channel has an interference level below the interference thresholdand is considered by the Spectrum Management algorithm suitable forhosting the Point-to-Point link.Grey Barred The system administrator has barred this channel from use. Forimproved visibility, an additional red ’lock’ symbol is used to indicatethat a channel is barredTable 13 Spectrum Management change state keyThe top of the colored bar represents the 99.9% percentile metric for specific channel. The ‘I’Bar is used to display the mean of means and peak of means metrics. The lower horizontal barrepresents the mean of means and the upper horizontal bar represents the peak of means. Thevertical bar is used as a visual cue to highlight the statistical spread between the peak and themean of the statistical distribution.8.3.7.8 Active Channel HistoryThe active channel history is a time series display of the channels used by the PTP 500 SeriesBridge over the last 25 hours. The active channel history is activated from the main SpectrumManagement page using the ‘Active Channel History’ hyperlink. An example of the active channelhistory display is shown in Figure 62. Where there are parallel entries on the display this signifiesthat the wireless link occupied this channel during the measurement period. The measurementperiods are one minute (from zero to sixty minutes) and twenty minutes from (60 minutes to twentyfive hours).Figure 62 Active Channel History Screen
Web Page Reference1058.3.7.9 Viewing Historic Spectrum Management MetricsSpectrum Management allows the system administrator to view the results of previous measure-ment quantization periods. Holding down the shift key and clicking the appropriate channel on thelocal channel spectrum plots activates this feature. This feature is available on both the masterand slave web page.Figure 63 Spectrum Management Time Series PlotFigure 63 shows an example time series plot. A time series plot displays the previous 132 measure-ment quantization periods. If the PTP 500 Series Bridge has not been running for 132 quantizationperiods then only the number of measurement quantization periods that are available are displayed.GREEN Peak of Means interference measurementBLACK 99.9% percentile of means intinterference measurementBLUE Mean of means interference measurementTable 14 Spectrum Management Time Series Key8.3.8 Spectrum Management (Fixed Frequency)The PTP 500 Series Bridge software allows a user to optionally fix transmit and receive frequenciesfor a wireless link. Once configured, the spectrum management software will not attempt to movethe wireless link to a channel with lower co and adjacent channel interference. Therefore this modeof operation is only recommended for deployments where the installer has a good understandingthe prevailing interference environment. (See Section 8.3.4.3 “Wireless Configuration”). Caremust also be taken to ensure that the frequency allocations at each end of the link are compatible.To help the user when identifying the mode of operation Spectrum Management uses two visualcues. See Figure 64.The main page title identifies the mode of operation using the “Fixed Frequency Mode” postfixand the selected channels are identified by a red capital ‘F’.
Web Page Reference106Figure 64 Spectrum Management Fixed Frequency ScreenChannel barring is disabled in fixed frequency mode; it is not required as dynamic channel hoppingis prohibited in this mode.The only controls available to the master are the Statistics Window and Interference Thresholdattributes. They will have no effect on the operation of the wireless link and will only effect thegeneration of the channel spectrum graphics.The active channel history menu is removed in this mode of operation as channel hopping isprohibited.

See Figure 66 and Figure 67.•The only controls available to the master are the Interference Threshold attribute. This hasno effect on the operation of the wireless link and will only affect the generation of the channelspectrum graphics. See Figure 66.•Extra color coding of the interference histogram is provided. See Table 15.When operating with RTTT (Road transport and Traffic Telematics) Avoidance enabled orother regulatory restrictions on channel usage the following variances apply:•All channels marked with a ‘no entry’ symbol with their associated statistics colored black arethe prohibited channels. See Figure 66 and Figure 67. These channels are never used tohost the wireless link, but CAC measurements are still taken so that adjacent channel biasescan be calculated correctly and so the user can see if other equipment is in use.

Refer to Section 8.1.1 “Home Page Alarm Display” for a description of allthese alarms. Checking the control “Enabled Diagnostic Alarms” in SNMP and/or SNTP selectsall the alarms shown in Figure 70. Users can access the sub-menu “Diagnostic Alarms” to modifythe alarms selected.
Web Page Reference114Figure 70 Remote Management – Diagnostic AlarmsFor a copy of the Motorola proprietary version 1 and version 2 MIB RFCs please consult theinstallation CD8.3.10.6 SNMP ConfigurationSNMP State:The SNMP state attribute controls the creation of the SNMP features. Changingthe SNMP state attribute requires a mandatory reboot of the unit. Only when the SNMP state isenabled at system start-up will the SNMP processor task be created.SNMP Enabled Traps:The SNMP Enabled Traps attribute controls which SNMP Traps theunit will send.
Web Page Reference115SNMP Community String:The SNMP community string acts like a password between thenetworks SNMP management entity and the distributed SNMP clients (600 Series bridge). Onlyif the community string is configured correctly on all SNMP entities can the flow of managementinformation take place. By convention the default value is set to ‘public’. When the communitystring is changed the system requires a mandatory reboot before the new string or phrase isadopted.SNMP Port Number:Is the port the SNMP management agent is listening to for commandsfrom an SNMP manager. The default value for this port number is 161.SNMP Trap IP Address:Is the address of either the network SNMP manager or Trap receiver.When asynchronous events (traps in SNMP terminology) are generated, the client unicasts theseto this IP Address. When the address is changed the system requires a mandatory reboot beforethe setting is adoptedSNMP Trap Port Number:The SNMP Trap Port Number is the port number of either thenetworked SNMP manager or Trap receiver. By convention the default value for the port numberis 162. When the port number is changed the system requires a mandatory reboot before thesetting is adopted.WiMAX Control:Enables and Disables the WiMAX (802.16) MIB. This control is only displayedwhen ‘Fixed Frequency’ is selected during installation.8.3.10.7 SMTP (Simple Mail Transport Protocol)The SMTP client is an alternative method for the 500 Series bridge to alert a system administratorwhen there are or have been system errors SMTPEmail Alert:This attribute controls the activation of the SMTP client.SMTP Enabled Messages:The SMTP Enabled Messages attribute controls which email alertsthe unit will send.SMTP IP Address:The IP address of the networked SMTP server.SMTP Port Number:The SMTP Port Number is the port number used by the networkedSMTP server:By convention the default value for the port number is 25.SMTP Source Email Address:The email address used by the 500 Series to log into the SMTPserver. This must be a valid email address that will be accepted by your SMTP Server.SMTP Destination Email Address:The email address to which the 500 Series bridge will sendthe alert messages.8.3.10.8 SNTP (Simple Network Time Protocol)The SNTP client allows the 500 Series to obtain accurate date and time updates from a networkedtimeserver. The system time is used for SNMP and event logging.SNTP State:When enabled, the Remote Management web page permits the following attributesto be set.
Web Page Reference116SNTP IP Address:The IP Address of the networked SNTP Server.SNTP Port Number:The port number of the networked SNTP server. By convention the defaultvalue for the port number is 123.SNTP Poll Interval:The period at which the SNTP client polls the server for time correctionupdates. Default 1 hour. If for any reason an SNTP poll fails, the client will automatically perform3 retries before waiting for the user defined poll period.Time Zone:The time zone is a fixed offset from GMT that is added to the SNTP time to allowthe expression of time in all geographic time zones.Daylight Saving:Allows a fixed offset of one hour to be added to the SNTP time in order toreflect the local daylight saving time.8.3.10.9 Setting the ClockThe PTP 500 Series bridge has a system clock which can be used to supply accurate date andtime information in the absence of a SNTP server. The system clock is battery backed and willcontinue to operate for several days if the 500 Series bridge has been switched off.SNTP State:If the SNTP State is set to “Disabled”, see Figure 68, then the Remote Manage-ment web page allows the following attributes to be set:Set Time:Shows the current time in 24 hour mode. The three editable fields display hours minutesand seconds.Set Date:Displays the current date. The year, month and day can be set using the drop-downselection boxes.Time Zone:See Section 8.3.10.9 “Setting The Clock”.Daylight Saving:See Section 8.3.10.9 “Setting The Clock”8.3.11 DiagnosticsTo further enhance the diagnostic capabilities of the PTP 500 Series, the storage of link performancehistograms has been extended to 31. To optimize RAM (volatile memory) usage a cascadinghistogram approach has been adopted. The root histogram is identical to the histograms in earlierreleases of the software, that is data is stored for one hour at a resolution of one second. Previously,the histograms were simple cyclic buffers which never stored more that the last one hour of data.The new cascading histogram approach daisy chains multiple histograms together. When the firsthistogram fills up the overflow from the first is used as an input to the next histogram in line.To optimize memory utilization, a statistical analysis is performed on the overflow to reduce theamount of data to be stored. In the case of the PTP 500 Series the cascading histograms aredefined as:•Histogram 1: 1 hour at a resolution of 1 second•Histogram 2: 24 hours at a resolution of 1 minute•Histogram 3: 30 Days at a resolution of 1 hour
Web Page Reference117For example, when histogram 1 fills up and starts to overflow the first minute of overflow is analyzedand the maximum, minimum and mean over that minute are computed and inserted into histogram2. When histogram 2 fills up and starts to overflow the first hour of overflow is analyzed and themaximum, minimum and mean over that hour is computed and inserted into histogram 3. Whenhistogram 3 starts to overflow, the overflow data is simply discarded.8.3.11.1 Diagnostic PlotterNew for the PTP 500 Series is the system administration diagnostic plotter facility see Figure 71:Figure 71 Diagnostic PlotterThe diagnostic plotter allows the system administrator to view the cascading histogram data inan easily accessible graphical form. The plot always displays three traces, maximum, minimumand mean by default. The diagnostic selector allows the user to select the various categories ofhistogram.The histograms that are available are:•Vector Error•Rx Power•Tx Power•Signal Strength Ratio•Link Loss•Rx Data Rate
Web Page Reference118•Tx Data Rate•Aggregate Data RateThe diagnostic plotter uses a novel time representation in the x-axis which compresses the timelineof the plot without sacrificing resolution.The trace selection allows the user to control which traces are plotted.As with other management pages the page refresh period can be used to interactively monitor thewireless link.8.3.11.2 Diagnostics DownloadThe diagnostics Download page allows the system administrator to download snapshots of systemdiagnostics.Figure 72 CSV DownloadThe following diagnostics are available:•Vector Error•Rx Power•Tx Power•Signal Strength Ratio V/H•Link Loss•Rx Data Rate•Tx Data Rate•Aggregate Data Rate•Receive SNR•Rx GainAll diagnostics are extracted from the associated status and statistics web page histograms. Theyare translated in a CSV file containing at most 578425 entries.
Web Page Reference119255784 entries comprises 3600 entries for the first hour, 1440 entries for the next 24 hours and 744entries for the next 31 days.8.3.12 Change System Administration PasswordThis page (Figure 73) is used to change the password for the system administration (The factorydefault is blank).Figure 73 Password ChangeTo change the password any combination of alphanumeric characters, up to 31 characters in length,can be used.8.3.13 License KeyThe License Key data entry page allows the system administrator to update the 500 Series bridgelicense key. Figure 74 shows a sample license key data entry page.

Web Page Reference1228.3.15 RebootThe reboot page allows the system administrator to perform commanded reboots of the wirelessunit. The reboot page also allows the system administrator to view a list of past reboot reasons.The “Previous Reasons For Reset/Reboot” field has been implemented as a drop down selectionbox, where the latest reason for reboot is located at the top of the list.If the SNTP service from the remote management section above is active, or the system time hasbeen set, then the command reboot reason will be accompanied by the date and time at which thereboot occurred.Figure 78 System RebootFigure 79 Reboot Confirmation Pop Up
Recovery Mode1239 Recovery ModeThe Motorola PTP 500 point-to-point wireless Ethernet bridges have a special mode of operationthat allows the user to recover a unit from configuration errors or software image corruption.Recovery mode is entered by depressing the Recovery Switch located on the underside of the PIDUPlus while applying mains power, as shown in Section 3.3.2 “PIDU Plus - PTP 500 Series Bridge”.The Recovery Switch should be held in the depressed state for between 10 and 20 seconds afterthe application of mains power. The Ethernet LED will flash with 10 double flashes at power up(following the release of the Recovery switch).When in recovery mode the user will be able to access the unit via the Ethernet interface. TheEthernet interface will have its IP address set to 169.254.1.1 (or 10.10.10.10 see Section 7.7.10“Powering Up”). On connection to a unit in recovery mode the following screen is displayedFigure 80:Figure 80 Recovery Mode Warning PageClicking on the warning page image will take the user on to the Recovery Option Page (Figure 81).

Fault Finding13210 Fault FindingIf communication has been lost with the unit at the near end of the link then there may be ahardware fault with the wiring, network or hardware. Go to the hardware section below. Ifcommunication with the far end of the link is lost then go to the radio section below.10.1 HardwareIf there are problems suspected with the link hardware the following procedure is recommended.10.1.1 PowerCheck the power LED at each end of the link. If the power lights are illuminated go to the Ethernetsection below. If at either end they are not illuminated then21 check the power source. If neitheris illuminated then there is no voltage on the power wires to the ODU.•Check that the mains power is connected and switched on.•Check that the power LED illuminates if the ODU connector is disconnected at the PIDU Plus(Open the PIDU Plus flap on the left hand side).If it does illuminate then either the ODU is drawing too much current, or the power wiring to theODU is short circuit or the PSU is supplying insufficient power. The likely fault can be determinedby removing the jumper (J906), found inside the removable cover of the PIDU Plus, and measuringthe current taken with an ammeter placed across the 2 jumper pins. This is normally 10mA withoutthe ODU connected and 300mA to 1A when the ODU is connected.If it does not illuminate then recheck that power is applied to the PIDU Plus by measuring thevoltage across +55V and 0V pads inside the removable cover in the PIDU Plus. Check that thePIDU Plus is not short circuit by measuring the impedance across the Power connector. Is the ledfaulty?10.1.2 EthernetThe Ethernet LED is driven from the ODU processor and thus is capable of informing you of manyconditions using different flash sequences. If the Ethernet indicator does not illuminate at all thereare four possible conditions.1. There is no power reaching the ODU because of a wiring fault2. The ODU is faulty3. The PIDU Plus is faulty4. The Ethernet network side is faultyLook at the following table to check the LED response for power up, disconnect the power andreapply and note what happens.The power indicator LED should be continually illuminated.21
Fault Finding133Differentiating between 1-3 and 4 can be achieved by removing the power for 1 second. Watchthe Ethernet indicator for 1 minute while power is removed, if it never flashes then the problem is1-3. Take the jumper (J905) out of the PIDU Plus and check the current taken by the ODU. Thisshould be 300mA to 1A when starting to run normally.If the Ethernet indicator flashes to begin with but then stops flashing, the ODU is powered andsoftware loaded but Ethernet connectivity has been lost between the ODU and the users connectedequipment. All Ethernet connections should be rechecked.Power Indoor Unit LED check chart:Mode Green LED Yellow LED No EthernetCable ConnectedYellow LED EthernetCable Connectedbetween PIDU Plus andNIC/Switch/HubNo Power Applied Off Off OffPower Applied On Will flash once persecond regularlyapproximately 30 secondsafter power applied for10 seconds then will goout and stay outWill flash once persecond regularlyapproximately 30 secondsafter power applied for10 seconds then operateas EthernetLink/Activity LEDValid Ethernet Link andno trafficOn N/A Will be on solid for avalid link.Valid Ethernet Link withtrafficOn N/A Will be on solid, but willblink randomly as trafficpasses through.Recovery Switch Pressedand held for greater than10 seconds from power on(Recovery is pressedwhile power is applied)On Off while switch pressed.

Unplug the RJ45from the PIDU+ and check the following resistances at the RJ45:1. Check the cable resistance between pins 1 & 2, 3 & 6, 4 & 5 and 7 & 8 at the RJ45.2. Check against column 2 in Table 17. Resistances for each pair should be within 1 ohm of eachother.
Fault Finding1343. Check the cable resistance between pins 1 & 3 at the RJ45. Check against column 3 inTable 17.4. Check the cable resistance between pins 4 & 7 at the RJ45. Check against column 4 inTable 17.5. Ensure that there is greater than 100K ohms between pins 1 & 8 for all cable lengths.6. Ensure that there is greater than 100K ohms between pin 1 and ODU ground for all cablelengths.7. Ensure that there is greater than 100K ohms between pin 8 and ODU ground for all cablelengths10.2 Radio10.2.1 No ActivityIf communication over the radio link has been lost and the unit at the other end of the link can bemanaged on its local network, the following procedure should be adopted: If there is no wirelessactivity then the configuration should be checked. It is essential that the following items arecorrect:•Check for Alarm conditions on Home page•Check that the software at each end of the link is the same version•Check that the Target Mac address has not been misconfigured at each end of the link•Check Range•Check Tx Power•Check License keys to ensure that both units are the same product variant•Check Master/Slave status for each unit and ensure that one unit is Master and the other unitis slave•Check that the link has not been further obscured or the ODU misaligned•Check the DFS page at each end of the link and establish that there is a quiet wireless channelto use If there are no faults found in the configuration and there is absolutely no wireless signalretry the installation procedure. If this doesn’t work then the ODU may be faulty.10.2.2 Some ActivityIf there is some activity but the link is unreliable or doesn’t achieve the data rates required then:•Check that the interference has not increased using the i-DFS measurements•If a quieter channel is available check that it is not barred•Check that the path loss is low enough for the communication rates required•Check that the ODU has not become misaligned

However 100% protection is neither implied nor possible.11.1 OverviewThe idea of lightning protection is to protect structures, equipment and people against lightningby conducting the lightning current to ground via a separate preferential solid path.The following should be treated as a guide only, the actual degree of lightning protection requireddepends on local conditions and weather patterns and applicable local regulations.Full details of lightning protection methods and requirements can be found in the internationalstandards IEC 61024-1 and IEC 61312-1, the U.S. National Electric Code ANSI/NFPA No. 70-1984or section 54 of the Canadian Electric Code.11.1.1 Lightning Protection ZonesThe installation of the ODU can be classified into two different lightning protection zones.Zone A - In this zone a direct lighting strike is possible. Zone B - In this zone a direct lightningstrike is unusual, but the full electromagnetic field is still present.The zones are determined using the ‘rolling sphere method’, an imaginary sphere, typically 50meter in radius is rolled over the structure. All structure points that contact the sphere, (Zone A)indicate the zone where a direct strike is possible. Similarly points that do not contact the sphereindicate a zone (zone B) where a direct strike is less likely.The following diagrams (Figure 94 and Figure 95) show this zoning pictorially:Equipment mounted in Zone A should be capable of carrying the full lightning current. Mounting ofthe ODU in Zone A is not recommended. Mounting in Zone A should only be carried out observingthe rules governing installations in Zone A22 Failure to do so may put structures, equipment andlife at risk.Equipment mounted in Zone B should be grounded using grounding wire of at least 10 AWG. Thisgrounding wire should be connected to a grounding rod or the building grounding system beforeentry in to building.The PTP 500 Series bridge ODU grounding point can be found on the bottom of the unit. The600 Series Bridge is supplied with an appropriate grounding lug for attachment to the ODU.Local regulations may also require the fitting of the 8 AWG ground wire referred below.22

This may be as frequent as every 10 meters (33 feet).Figure 96 includes illustrations showing the placement of the PTP lightning protection units andthe recommended components for typical Mast/Tower or Wall installations.

Lightning Protection14011.3.1 Pre-Power TestingBefore plugging the RJ45 from the lower LPU (or if not fitted the ODU) into the PIDU, check thefollowing resistances at the RJ45:1. Check the cable resistance between pins 1&2, 3&6, 4&5 and 7&8 at the RJ45. Check againstcolumn 2 in Table 17. Resistances for each pair should be within 1 ohm of each other.2. Check the cable resistance between pins 1&3 and 4&7 at the RJ45. Check against columns 3and 4 respectively in Table 17.3. Ensure that there is greater than 100K ohms between pins 1&8 for all cable lengths.4. Ensure that there is greater than 100K ohms between pin 1 and ODU ground for all cablelengths.5. Ensure that there is greater than 100K ohms between pin 8 and ODU ground for all cablelengths.CAT-5 Length(Meters)Resistancebetween pins 1&2,3&6 , 4&5 andpins 7&8 (ohms)Resistancebetween pins 1&3(ohms)Resistancebetween pins 4&7(ohms)0 0.8 1.0 1.610 2.5 2.7 3.320 4.2 4.4 5.030 5.9 6.1 6.740 7.6 7.8 8.450 9.3 9.5 10.160 11.0 11.2 11.870 12.7 12.9 13.580 14.4 14.6 15.290 16.1 16.3 16.9100 17.8 18.0 18.6Table 17 Resistance Table Referenced to the RJ45 at the PIDU Plus11.3.2 Post-Power TestingThe Correct Operation is as follows:
Lightning Protection1411. Connect the RJ45 to the PIDU and apply power to the PIDU, the power LED should illuminatecontinuously.2. 30 seconds after powering, the Ethernet LED should be observed starting with 10 slow flashes.3. If there is a network connection the Ethernet LED will then show Ethernet activity.If the system does not operate corrctly, refer to the fault finding below.The PIDU Green power LED does not illuminateUnplug the ODU connection from thePIDU and check the power LED illumination. If the power LED still does not light then check thepower source.The PIDU Green power LED flashesA flashing power LED indicates that there is a shortcircuit on the output of the PIDU. Check that pins 4&5 and 7&8 are not crossed with pins 1&2and 3&6 on the RJ45, and also greater than 100K ohms between pins 1&8.The Ethernet LED flashes ten times but does not show Ethernet activityFailure of theEthernet LED to show Ethernet activity can be due to wiring to pins 1&2 and 3&6 being incorrect,for example if the wiring to pins 1 and 3 are crossed.The Ethernet connection to the network is only 10/100BaseT, when 1000BaseT wasexpectedIt is likely there is a fault with the wiring to pins 4&5 and 7&8.
Lightning Protection14211.4 Locating the FaultHaving identified which of the wiring cores are likely to be connected incorrectly, the location ofthe faulty cable can be narrowed by disconnecting sections of the drop cable and by unpluggingthe relevant RJ45 connectors from the LPUs.As a further aid to locating the fault the Ethernet connections are also available inside the LPU.The connections can be accessed by rotating the LPU lid as shown in Figure 99 The Lid nut onlyneeds to be slacken, do not remove. Test point P1 on the LPU PCB corresponds to pin 1 on theRJ45 etc.An indication of power on the Ethernet cable is also provided inside the LPU, LED PWR1 willilluminate in the case of the PTP600 series, LED PWR2 should not.Figure 99 PTP LPU test Points
Wind Loading14312 Wind Loading12.1 GeneralAntennas and electronic equipment mounted on towers or pole mounted on buildings will subjectthe mounting structure to significant lateral forces when there is appreciable wind. Antennas arenormally specified by the amount of force (in pounds) for specific wind strengths.The magnitude of the force depends on both the wind strength and size of the antenna.12.2 Calculation of Lateral ForceThe 500 Series bridge with or without the integral antenna is essentially a flat structure and sothe magnitude of the lateral force can be estimated from:Force (in pounds) = 0.0042 . A . v2Where A is the surface area in square feet and v is the wind speed in miles per hour.The lateral force produced by a single 500 Series bridge (integrated or connectorized model) atdifferent wind speeds is shown in Table 18 and Table 19.Largest Surface Area (sqft)Lateral Force (Pound)at wind speed (mph)80 100 120 160 200PTP 500 Series Bridge -Integrated1.36 27 41 57 101 164PTP 500 Series Bridge -Connectorized1.00 27 42 60 98 N/ATable 18 Lateral Force – ImperialLargest Surface Area (sq m) Lateral Force (Kg)at wind speed(m/s)30 40 50 60 70PTP 500 Series Bridge - Integrated 0.130 12 22 34 49 66PTP 500 Series Bridge -Connectorized0.093 9 16 24 35 48Table 19 Lateral Force – Metric

The installer should ensure that the structure to which the 500Series Bridge is fixed to is also capable of withstanding the prevalent wind speeds and loads.12.4 Wind Speed StatisticsInstallers are recommended to contact the national meteorological office for the country concernedto identify the likely wind speeds prevalent at the proposed location. This will enable the installerto estimate the total wind loading on the support structures.Examples of the sort of statistics that are available are:USA - Reported Fastest Single Wind Velocities for Selected U.S. Cities (Source: National WeatherService)City, State Wind Velocity (mph)Bismark, North Dakota 72Buffalo, New York 91Chicago, Illinois 87Hatteras, North Carolina 110Miami, Florida 132New York, New York 99Pensacola, Florida 114UK Meteorological Office, http://www.meto.gov.ukPeak wind speed contour maps can be found as Fig 3a/3b at:http://www.meto.gov.uk/education/historic/1987.html
PTP 500 Series Bridge - Connectorized Model14513 PTP 500 Series Bridge - Connectorized Model13.1 ScopeThis section details the changes and additional features relevant to the connectorized version ofthe PTP 500 Series products..13.2 Product Description13.2.1 HardwareThe Connectorized PTP 500 Series Bridge is a variant designed to provide the system integratorand installer with the ability to provide extra capability to cope with very difficult radio linkscompared to the PTP 500 Series Integrated model. The variant allows the use of a variety ofexternally mounted antennas, either Flat Plate or Dish, which have higher gains than provided bythe integrated antenna that is normally used.Figure 100 Connectorized 500 Series Bridge Outdoor Unit13.2.2 Antenna Choices – 5.8 GHzThe integrated antenna has a gain of 23.5 dBi.
PTP 500 Series Bridge - Connectorized Model146In non-FCC regions antenna choice is not restricted but any region specific EIRP limit must beobeyed by reducing the maximum Transmit power23, see Table 6 in Section 5.2 “Region Codes”.In FCC regions external antennas from the list in Section 13.6.3 “Antennas for USA / Canada –5.8 GHz” can be used with the Connectorized version of the 500 Series Bridge. These are approvedby the FCC for use with the product and are basically constrained by the following limits:•Single Polarization Flat Plate Antennas – up to 28 dBi per antenna.•Single/Dual Polarization Parabolic Dish Antennas – up to 37.7 dBi per polarization or antenna.In FCC regions when using external antennas – cable loss between the connectorized version ofthe 500 Series Bridge and the antenna ports must not be less than 1.2 dB.13.2.3 Antenna Choices – 5.4 GHzThe integrated antenna has a gain of 23.5 dBi.In FCC regions external antennas from the list in Section 13.2.3 “Antenna Choices – 5.4 GHz”can be used with the Connectorized version of the 500 Series Bridge. These are approved by theFCC for use with the product and are basically constrained by the following limits:•Single/Dual Polarization Parabolic Dish Antennas – up to 34.6 dBi per polarization or antenna.However, the Maximum Transmit Power must be reduced to avoid exceeding the EIRP limits. InFCC regions when using external antennas – cable loss between the connectorized version of the500 Series Bridge and the antenna ports must not be less than 1.2 dB.13.3 Software/FeaturesThe connectorized variant operates in the same way as the basic 500 Series and is released initiallywith the feature set to the Connectorized 500 Series variant. The areas where the functionality ismodified are:13.3.1 Status PageThe link loss calculation presented on the Status Page of the management interface has to bemodified to allow for the increased antenna gains at each end of the link. The manufacturingprocess of the Connectorized 500 Series Bridge configures the standard hardware of the unit foruse with external antennas. The installer is prompted, as part of the installation process, to enterthe gain of the external antenna(s) and cable losses at each end of the link.Peer-to-peer messaging is used to pass the effective antenna gain to each end of the link so thatthe link loss calculations can be correctly computed.Maximum Transmit Power Allowed = EIRP Limit – Antenna Gain + Cable Losses; set the power to the 1dB value23lower than the actual value calculated.

PTP 500 Series Bridge - Connectorized Model14813.3.3 Installation PagesThe installer is prompted to enter the Antenna Gain and Cable Loss (Connectorized PTP 500 SeriesBridge to antenna) at each end of the link. The Installation Page(s) is shown as Figure 103 toFigure 105.Figure 103 Connectorized PTP 500Series Bridge ‘Installation Wizard’ PageAntenna Gain:Gain of the antenna you are connecting to the unit, see table in Section 13.2.3“Antenna Choices – 5.4 GHz”.Cable Loss:Loss in the cable between the ODU and the antenna. Note: In the event that there isa significant difference in length of the antenna cables for the two antenna ports, then the averagevalue should be entered.
PTP 500 Series Bridge - Connectorized Model149Spectrum Management Control:Is used to configure the 500 Series Bridge Spectrum Man-agement features, see Section 8.3.7 for more details. iDFS is the abbreviation for intelligentDynamic Frequency Selection, which continually monitors the spectrum looking for the channelwith the lowest level of on channel and co-channel interference. Fixed frequency mode allowsthe installer to fix the Transmit and receive frequencies on the units. The frequencies may beconfigured symmetrically or asymmetrically.Figure 104 Connectorized 500 Seriesbridge ‘Confirm Installation’ Page
PTP 500 Series Bridge - Connectorized Model150EIRP:The Confirm Installation Page displays the EIRP (Effective Isotropic Radiated Power),which describes the strength of the radio signal leaving the wireless unit. This allows the operatorto verify that their link configuration (Max Transmit Power, Antenna Gain and Cable Loss) donot cause the link to exceed any applicable regulatory limit.Figure 105 Connectorized 500 Series bridge ‘Disarm Installation’ Page13.4 Deployment ConsiderationsThe majority of radio links can be successfully deployed with the 500 Series. It should only benecessary to use external antennas where the Link Estimator indicates marginal performance for a
PTP 500 Series Bridge - Connectorized Model151specific link – for example when the link is heavily obscured by dense woodland on an NLOS linkor extremely long LOS links (>80km or >50 miles) over water.The external antennas can be either dual-polarization (as the integrated antenna) or two singlepolarized antennas can be used in a spatially diverse configuration. It is expected that the dual-polarization antennas would normally be used to simplify the installation process; spatially diverseantennas may provide additional fade margin on very long LOS links where there is evidence ofcorrelation of the fading characteristics on Vertical and Horizontal polarizations.Dual polarization antennas (with a gain greater than the integrated antenna) are currently onlyavailable in parabolic dish form.13.5 Link BudgetAn estimate of the link budget for a specific application can be obtained by using the MotorolaSystems link estimation tools. For more information see the Motorola web site.13.6 Regulatory IssuesInstallations must conform to any applicable local regulations for the Equivalent Isotropic RadiatedPower (EIRP).Ensuring compliance becomes more complex when the connectorized unit is used with externalantennas which may be locally sourced. With higher gain external antennas fitted, the MaximumTransmit power may need to be reduced for operation in specific countries.See table in Section 5.2 for any EIRP restrictions that may apply in your region.In some regions, operation of the PTP54500 products is constrained by an EIRP limit. The normalconstraint is that the EIRP does not exceed 30 dBm (33 dBm for PTP58500) for radio signals witha bandwidth of >=20 MHz. As the PTP54500 operating bandwidth is approximately 27 MHz,then the limit is 30 dBm EIRP (33 dBm for PTP58500).When operating with external antennas, the installer/operator has to set the maximum transmitpower to ensure that the EIRP limit is not exceeded. The Set_Max_Transmit_Power is calculatedas below:Set_Max_Transmit_Power = [Max_Transmit_Power] rounded down to nearest lower dB.13.6.1 Antenna Choice (FCC and Industry Canada Regions Only)The antennas which can be deployed with the Connectorized 500 Series Bridge are shown inSection 13.6.3 “Antennas for USA / Canada – 5.8 GHz” and Section 13.6.4 “Antennas forUSA / Canada – 5.4 GHz”.For FCC and Industry Canada, the PTP500 Series Bridge has been designated to operate with theantennas listed in Section 13.6.3 “Antennas for USA / Canada – 5.8 GHz” and Section 13.6.4“Antennas for USA / Canada – 5.4 GHz”, and having a maximum gain of 37.7 dB (34.9 dB for5.4 GHz product variant). Antennas not included in these tables or having a gain greater than37.7 dB (34.9 dB for 5.4 GHz product variant) are strictly prohibited for use with this device. Therequired antenna impedance is 50 ohms.
PTP 500 Series Bridge - Connectorized Model15213.6.2 Cable Losses (FCC Regions Only)The FCC approval for the product is based on tests with a cable loss between the units of ap-proximately 1.2dB at 5.8GHz. The use of lower cable losses would result in the installation beingoutside the FCC rules.As an indication, 1.2dB of cable loss corresponds to the following cable lengths excluding connectorlosses (source: Times Microwave).Cable Lengthfor1.2dBCableLoss at5.8GHz(ft) (m)LMR100 1.9 0.6LMR200 4.6 1.4LMR300 7.25 2.2LMR400 11.1 3.4LMR600 16.5 5.0Table 20 CableLosses per Length

The actual installation procedure will dependon antenna choice, cable choice, required antenna separation etc.13.7.1 Antenna ChoiceSection 13.6.3 “Antennas for USA / Canada – 5.8 GHz” and Section 13.6.4 “Antennas for USA/ Canada – 5.4 GHz” show a wide variety of antennas that can be used with the Connectorized PTP
PTP 500 Series Bridge - Connectorized Model159500 Series bridge. The main selection criteria will be the required antenna gain. The secondarycriteria should be the ease of mounting and alignment. For example the Radio Waves Parabolicdishes are supplied with a mount that allows adjustment for alignment independent of the actualantenna mounting. This type of antenna is much easier to align than those that have to be rotatedaround the mounting pole for alignment.13.7.2 Cables and ConnectorsCables should be selected using the above criteria. However it should be noted that a cable of atype similar to LMR400 is a lot more difficult to handle and route than a cable of a type similar toLMR100. Motorola recommends the use of weatherproof connectors – preferably, ones that comesupplied with adhesive lined heat shrink sleeve that is fitted over the cable/connector interface.The connectors required at the Connectorized 500 Series bridge end of the antenna cables areN-Type Male. The connectors required at the antenna end of the antenna cables is dependant onthe antenna type chosen.13.7.3 ToolsThe tools required for mounting a Connectorized 500 Series bridge unit are the same as thoserequired for an Integrated 500 Series bridge detailed in Section 7.3. The tools required formounting the antennas are specific to the antenna chosen. The installer should refer to the antennamanufacturer’s instructions.13.7.4 Miscellaneous suppliesThe following miscellaneous supplies will be required:•Cable ties, cable cleats – for securing cables•Self-amalgamating tape – to weatherproof the RF connectors•PVC tape – for additional protection of the RF connectors and securing cables13.7.5 Mounting the Connectorized 500 Series BridgeA Connectorized 500 Series bridge is shipped with the same bracket as supplied with an Integratedunit. Details on the use of this bracket can be found in Section 3.3.7. The 500 Series Bridge shouldbe mounted in a position that gives it maximum protection from the elements, but still allows easyaccess for making off the various connections and applying the recommended weatherproofing.When using dual polar antennas the Connectorized 500 Series bridge should be mounted in sucha position as to minimize the cable length, keeping losses to a minimum (taking into account theminimum cable lengths required by the FCC regulations, see Section 13.6.3 “Antennas for USA/ Canada – 5.8 GHz” .When using separate antennas the Connectorized 500 Series Bridge should be mounted in such aposition as to minimize both cable runs between the unit and the antennas. It is not necessary tomount the Connectorized 500 Series Bridge at the mid point between the antennas.
PTP 500 Series Bridge - Connectorized Model16013.7.6 Mounting the antennasThe Antennas should be mounted according to the manufacturer’s instructions. Actual antennaposition will depend on the available mounting positions and link requirements. It may be necessaryto mount the antennas 20m apart or at a certain distance from the ground to get the desired results.13.7.7 Alignment ProcessWhen aligning antennas deployed with a Connectorized 500 Series bridge unit it may not bepossible to hear the alignment tone emanating from the unit. In this case it may be necessary fora second installer to assist in the operation. Alternatively, it may be possible to extend the tubeon the supplied stethoscope to give a longer reach.Tip: Fine antenna alignment can sometimes be achieved by tightening and loosening the bolts oneither side of the antenna mounting bracket, rather than trying to turn the whole bracket on themounting pole.13.7.8 Aligning Dual Polar AntennasThe process for aligning a dual polar antenna is the same as aligning an Integrated unit with anintegrated antenna. This procedure is detailed in Section 7.7.11 “Aligning the PTP 500 SeriesBridge ODUs”.13.7.9 Aligning Separate AntennasWhen using separate antennas to achieve spatial diversity, one should be mounted with Horizontalpolarization and the other with Vertical polarization.The following steps should be followed:Step 1: Mount the AntennasStep 2: Mount the connectorized version of the PTP 500 Series Bridge unitStep 3: Route and make off the ends of the Antenna cablesStep 4: Connect the antenna cables at the antennasStep 5: Connect one of the antenna cables at the Connectorized version of the 500 Series bridgeunit.Step 6: Connect the Connectorized 500 Series Bridge ODU to PIDU Plus cable and configure theunit as described in Section 7.7 “Connecting Up”.Step 7: Align the connected antenna using the tones as described in Section 7.7.11 “Aligningthe PTP 500 Series Bridge ODUs”.Step 8: Connect the other antenna to the Connectorized 500 Series bridge.Step 9: Disconnect the cable to the already aligned antenna.Step 10: Align the second antenna using the tones as described in Section 7.7.11 “Aligning thePTP 500 Series Bridge ODUs”.Step 11: Re-connect the second antenna to the Connectorized 500 Series bridge (Note: you willnotice the tone pitch increase as you re-connect the second antenna due to the additional receivedsignal).Step 12: Use the relevant status web pages to check that you are getting the results you expectfrom your link planning.Step 13: Complete the installation as detailed below.
PTP 500 Series Bridge - Connectorized Model16113.7.10 Completing the InstallationThe installation should be completed by checking all mounting nuts bolts and screws, securing allcables and weatherproofing the installation. Warning: Finally tightening the antenna mountingsmay cause the antenna alignment to be altered, due to distortion in the mounting bracket causedby action of tightening. It is recommended that the installation tone be left turned on (armed)during this process so that any movement can be noticed and counteracted by tightening the otherside of the bracket.13.7.11 Antenna Cable FixingCables should be secured in place using cable ties, cleats or PVC tape. Care should be takento ensure that no undue strain is placed on the connectors on both the Connectorized 500 Seriesbridge and the Antennas and also to ensure that the cables do not flap in the wind. Flappingcables are prone to damage and induce unwanted vibrations in the mast to which the units areattached.13.7.12 Antenna Connection WeatherproofingWhere a cable connects to an antenna or unit from above, a drip loop should be left to ensure thatwater is not constantly channeled towards the connector.Figure 106 Forming a Drip LoopAll joints should be weatherproofed using self-amalgamating tape. It is recommended that alayer of PVC tape be placed over the self-amalgamating tape to protect the joint while the self-amalgamating tape cures and gives additional protection.Figure 107 shows this diagrammatically for the 500 Series bridge end of the antenna cables. Ifthe antenna manufacturer has not supplied guidance on this matter, the same technique should beemployed at the antenna end of the cable.

AES Encryption Upgrade17215 AES Encryption UpgradeThe Motorola PTP 500 Series bridges support link encryption using the NIST approved AdvancedEncryption Standard, HFIPS-197 UTH. This standard specifies AES (Rijndael) as a FIPS-approvedsymmetric encryption algorithm that may be used by U.S. Government organizations (and others)to protect sensitive information.Link Encryption is not available in the standard PTP 500 Series system. A license key to enable linkencryption can be purchased from your Motorola Point-to-Point Distributor or Solutions Provider.AES can be activated on receipt of the activation on the Motorola Systems Support Page.There are two levels of encryption that are available to purchase:•128-bit•128 and 256-bitOption 1 allows the user to encrypt all traffic sent over the wireless link using 128-bit encryption.Option 2 allows the user to encrypt traffic using either 128 or 256-bit encryption. The configurationprocess for both encryption variants is identical except for the selection of algorithm. The followingconfiguration example is for a 256-bit encryption key.15.1 Configuring Link EncryptionAfter purchasing AES encryption for the PTP 500 Series wireless link, two new license keys willbe issued, one for each end of the wireless link. The following configuration process gives a stepby step guide to enabling AES link encryption on a PTP 500 Series bridge.15.1.1 License KeysThe first step when configuring link encryption is to enter the new license keys in both 500 Serieswireless units.Figure 126 shows the license key data entry screen. This screen can only be accessed by thesystem administrator. If you do not have access to the PTP 500 Series system administrationpages then please contact your designated system administrator.It must be noted that configuring link encryption will necessitate a 500 Series bridge service outage.Therefore it is recommended that the configuration process be scheduled during an appropriateperiod of low link utilization. Motorola recommends the following process for entering new licensekeys and minimizing service outage.1. Open two browsers, one for each end of the link2. Navigate to the ‘License Key’ data entry page for each end of the link3. Enter the license keys and click the ‘Validate license key’ button at each end of the link. Thiswill allow the software to validate the license key prior to the system reset. (DO NOT CLICKARE YOU SURE POPUP DIALOG)
AES Encryption Upgrade173Figure 126 AES Software License Key Data Entry4. When both license keys have been successfully validated confirm the reboot for both ends ofthe link. The software is designed to allow five seconds so that a user can command both endsof the link to reset before the wireless link drops.5. The link will automatically re-establish.15.1.2 Encryption Mode and KeyEntering the license keys only does not initialize AES link encryption. Link encryption can onlybe enabled via the Configuration or Installation Wizard pages. Motorola recommends that theConfiguration page Figure 127 be used to configure AES link encryption.
AES Encryption Upgrade174Figure 127 AES Configuration Data Entry PageMotorola recommends the following process for entering AES link encryption configuration:-1. Open two browsers, one for each end of the link2. Navigate to the ‘Configuration’ data entry page for each end of the link3. At both ends of the link select the ‘AES (Rijndael)’ Encryption Algorithm required.4. At both ends of the link enter ether an 128-bit or 256-bit encryption key. Note the key consistsof 32/64 case insensitive hexadecimal characters. The same Key must be entered at both endsof the link. Failure to enter the same key will cause the link to fail.
AES Encryption Upgrade1755. Submit configuration on both ends of the link, but do not reboot.6. Reboot both ends of the link Figure 128. The software is designed to allow five seconds sothat a user can command both ends of the link to reboot before the wireless link drops.Figure 128 Configuration Reboot Screen15.2 Wireless Link Encryption FAQ15.2.1 Encryption data entry fields are not availableCheck that the correct license key has been inserted into the unit. The current license key isdisplayed on the ‘License Key’ data entry page.15.2.2 Link fails to bridge packets after enabling link encryptionIf the wireless link status on the status web page indicates that the link is ‘Searching’, and you canbrowse to the local end of the link but not to the remote end, then check that the same encryptionalgorithm and key have been entered at both ends of the link. Failure to enter the same algorithmand key will result in received packets not being decrypted correctly.15.2.3 Loss of AES following downgradeWhen downgrading (using Recovery software image 05-01 onwards) to an earlier version of softwarethat does not support AES, the unit will indicate that the region code is invalid. The user will berequired to re-install correct software (supplied when AES key was activated) and reboot the unit.

FAQs19418 FAQsCan I source and use my own PoE adaptor with the 500 Series bridge? No. The 500Series bridge uses a non-standard PoE configuration. Failure to use the Motorola supplied PowerIndoor Unit could result in equipment damage and will invalidate the safety certification and maycause a safety hazard.Why has Motorola launched the 500 Series bridge? The 500 Series bridge is the first productto feature Multiple-Input Multiple-Output (MIMO). The PTP 500 Series solutions allow wirelessconnections of up to 200km (124 miles) in near line-of-sight conditions and up to 10km (6 miles)in deep non-line-of-sight conditions.What is Multiple-Input Multiple-Output (MIMO)? The 500 Series bridge radiates multiplebeams from the antenna - the effect of which is to significantly protect against fading and toradically increase the probability that the receiver will decode a usable signal. When the effectsof MIMO are combined with those of OFDM techniques and a best in class link budget, there isa significant improvement to the probability of a robust connection over a non-line-of-sight path.What do you mean by “non-line-of-sight”? A wireless connection between two points withoutoptical line-of-sight, i.e., with obstructions between the antennas the transmitted signal is still ableto reach the receiver and produce a good quality link.What else is special about the 500 Series bridge ? There are many special features built-into the hardware of the 500 Series bridge. The product offers the highest system gain in its classthrough high sensitivity antennas for improved signal recovery. It also features a Software DefinedRadio system that operates on ultra fast digital signal processors but is controlled by firmwaregiving the ability to download new firmware when enhancements become available. The 500 Seriesbridge has a built-in web server for advanced management capabilities including detailed radiosignal diagnosis.In which frequency bands does the 500 Series bridge operate? The Motorola point-to-point 500 Series bridge operates in the unlicensed 5.4 GHz (ETSI Band B) and 5.8 GHz (ETSIBand C and FCC ISM band). This means no license is required to operate the 500 Series bridge.Why does the 500 Series bridge operate in the 5GHz band? The 5 GHz band offers thedual benefits of high data throughput and good radio propagation characteristics. The wide bandof spectrum available is subdivided into several channels such that multiple systems can operatein the vicinity without causing interference to one another.Is the 500 Series bridge an 802.11a device?No, although similar, the 500 Series bridge usesdifferent encoding and radio transmission systems from 802.11a. In areas where 802.11a systemsare operating, the 500 Series bridge will detect the 802.11a radio signals and choose a clear channelaway from any interference.How much power does the 500 Series bridge transmit?At all times the 500 Series bridgeoperates within country / region specific regulations for radio power emissions. In addition, the500 Series bridge uses a technique known as Transmit Power Control (TPC) to ensure that it onlytransmits sufficient radio power such that the other antenna can receive a high quality signal.How does the PTP 500 Series Bridge avoid interference from other devices nearby?At initialization, the 500 Series bridge monitors the available frequency channels to find a channel
FAQs195that is clear of interference. In operation 500 Series bridge continuously monitors the spectrum toensure it is operating on the cleanest channel.How does the 500 Series bridge integrate into my data network?The 500 Series bridgeacts as a transparent bridge between two segments of your network. In this sense, it can be treatedlike a virtual wired connection between the two buildings. The 500 Series bridge forwards 802.3Ethernet packets destined for the other part of the network and filters packets it does not needto forward. The system is transparent to higher-level management systems such as VLANs andSpanning Tree.How does the 500 Series bridge provide security for data traffic?The 500 Series bridgehas a range of security features. At installation time each link must be programmed with the serialID of its partner. The two ends of the link will only communicate with one another, eliminatingany chance of “man in the middle” attacks. Over the air security is achieved through a proprietaryscrambling mechanism that cannot be disabled, spoofed or snooped by commercial tools.Can I use Apple Macintosh OS X to control and monitor my 500 Series bridge?Yes,but there are some restrictions. Mozilla 1.6 or higher is recommended.
