All rights reserved. http://www.motorola.com/ptp Compliance General Changes or modifications not expressly approved by Motorola could void the user’s authority to operate the system. NOTE: This system has achieved Type Approval in various countries around the world. This means that the system has been tested against various local technical regulations and found to comply. The frequency bands in which the system operates may be ‘unlicensed’ and, in these bands, the system can be used provided it does not cause interference. Further, it is not guaranteed protection against interference from other products and installations.
2The system has been tested for compliance to both US (FCC) and European (ETSI) specifications. It has been shown to comply with the limits for emitted spurious radiation for a Class B digital device1, pursuant to Part 15 of the FCC Rules in the USA and appropriate European ENs. These limits have been designed to provide reasonable protection against harmful interference. However the equipment can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to other radio communications. There is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: • Reorient or relocate the Outdoor Unit (ODU). • Increase the separation between the affected equipment and ODU. • Connect the ODU/PIDU into a power outlet on a circuit different from that to which the receiver is connected. • Consult your installer or supplier for help. Deployment and Operation The Radio Regulations of various countries’ limits constrain the operation of radio products generally. In particular the local regulator may limit the amount of conducted or radiated transmitter power and may require registration of the radio link. The power transmitted by the PTP 500 Series Bridge is controlled by the use of Region-specific License Keys. The following examples show how the regulatory limits apply in some specific countries at the current time. Operators should note that regulations are subject to change. Contact your supplier/installer to ensure that your product is set for the correct License Key for your Country/Region and to ensure that you have fulfilled all the local regulatory requirements, especially if you are intending to use a link with external antennas. Notes below the tables indicate countries where registration of the link is currently mandatory. 1 Class B Digital Device, A digital device that is marketed for use in a residential environment, notwithstanding use in commercial, business and industrial environments.

2 Avoiding Hazards 222 Avoiding Hazards 2.1 Preventing Overexposure to RF Energy WARNING: To protect from overexposure to RF energy, install the radios for the 500 family of PTP wireless solutions so as to provide and maintain the minimum separation distances from all persons as shown in Table 3. When the system is operational, avoid standing directly in front of the antenna. Strong RF fields are present when the transmitter is on. The Outdoor Unit (ODU) must not be deployed in a location 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 generally accepted limits for the general population. NOTE: These are conservative distances that include compliance margins. 2.1.1 Calculations for Separation Distances and Power Compliance Margins Limits 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 Federal Regulations, as well as the guidelines and suggestions for evaluating compliance in FCC OET Bulletin 65. • Health Canada limits for the general population. See the Health Canada web site at http://www.hc-sc.gc.ca/ewh-semt/pubs/radiation/99ehd-dhm237/limits-limites_e.html and Safety Code 6. • EN 50383:2002 Basic standard for the calculation and measurement of electromagnetic field strength and SAR related to human exposure from radio base stations and fixed terminal stations for wireless telecommunication systems (110 MHz - 40 GHz) • ICNIRP (International Commission on Non-Ionizing Radiation Protection) guidelines for the general public. See the ICNIRP web site at http://www.icnirp.de/ and Guidelines for Limiting Exposure to Time-Varying Electric, Magnetic, and Electromagnetic Fields. The applicable power density exposure limits from the documents referenced above are: • 10 W/m2 for RF energy in the 2.4-, 5.2-, 5.4-, 5.8- and 5.9 GHz frequency bands.

3 Getting Started 273.3 Product Description This User Manual is specifically written for the 500 family of point-to-point broadband wireless solutions. The PTP 500 Series Bridge has been developed to provide Point-to-Point data connectivity via a 5.4 GHz or 5.8 GHz wireless Ethernet bridge operating at broadband data rates. The PTP 500 Series Bridge is aimed at a wide range of applications. An example application is an enterprise that has a requirement to connect together the Local Area Network (LAN) of two or more buildings as shown in Figure 1. Figure 1 - Typical PTP 500 Series Bridge Deployment The PTP 500 Series Bridge offers true non-line-of-sight (NLOS) operation by using a combination of Orthogonal Frequency Division Multiplexing (OFDM) modulation and Multiple-Input Multiple-Output (MIMO) techniques. These technologies enable the PTP 500 Series Bridge to drive through foliage and around buildings to such an extent that almost universal coverage can be expected at short range. A PTP 500 Series Bridge system consists of a pair of identical devices that are deployed one at each end of the link. At installation, the user sets up one unit as the Master and the other as the Slave. Either unit can be configured as Master or Slave.
3 Getting Started 28Each end of the link consists of: • An integrated (or connectorized - see section 13) outdoor transceiver unit containing all the radio and networking electronics hereafter referred to as the Outdoor Unit (ODU). • An indoor connection box containing a mains power supply, status indicators and network connection port. Hereafter referred to as the Power Indoor Unit Plus (PIDU Plus). A 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 of eight” mains plug. Connection between the ODU and PIDU Plus is made using standard CAT5e outdoor UV resistant cable. Connection between the PIDU Plus and the Network Equipment is made using standard CAT5e cable. 3.3.1 The Outdoor Unit (ODU) The ODU is a self-contained unit. It houses both radio and networking electronics. The ODU for the PTP 500 Series Bridge should only be deployed using the supplied PTP 300/500/600 Series Bridge PIDU Plus. Figure 2 shows an installation example of a PTP 500 Series ODU. Figure 2 – PTP 500 Series Bridge Outdoor Unit (ODU) with PTP-LPU
3 Getting Started 29 3.3.2 PIDU Plus – PTP 300/500/600 Series Bridge The PTP 300/500/600 Series Bridge PIDU Plus is used to generate the ODU supply voltage from the mains supply and inject this supply voltage into the 100BaseT 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 500 Series Bridge to a PIDU Plus ODU port as equipment damage may occur. The PTP 300/500/600 Series Bridge PIDU Plus is not interchangeable with the PTP 400 Series PIDU Plus. Figure 3 - Power Indoor Unit (PIDU Plus) – PTP 300/500/600 Series The 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 when there is Ethernet activity. The fact that it lights also indicates that the ODU is powered. At power 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 100BaseT Ethernet network port and the Recovery switch. Figure 4 – PIDU Plus Recovery Switch Location
3 Getting Started 30The Recovery switch is used to recover the unit from configuration errors or software image corruption. To put a PTP 500 Series Bridge into Recovery mode the Recovery switch should be pressed then the power applied. The Recovery switch should be kept pressed for at least 30 seconds after the 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 300/500/600 Series Bridge PIDU Plus. On the left hand side of the PIDU Plus, 48V DC input and output connections can be found. These are used to power the PTP 500 Series Bridge from an external DC source or to provide a level of power supply redundancy, as shown in Section 3.3.3 “Redundancy and Alternative Powering Configurations”. WARNING When using alternative DC supplies the supply MUST comply with the following requirements: • 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 300/500/600 Series Bridge PIDU Plus, connectors and jumpers can be 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”.
3 Getting Started 31The input supply range for the 300/500/600 Series PIDU Plus is 90V-264V AC, 47-63Hz. Mains connection to the PIDU Plus is made using a standard “figure of eight” mains lead as shown in Figure 6. Figure 5 –PTP 300/500/600 Series Bridge PIDU Plus Power Input 3.3.3 Redundancy and Alternative Powering Configurations NOTE: The use of DC supplies of less than 55v will reduce the usable distance between the PIDU Plus and ODU. CAUTION: 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 Only For use where there is no mains supply. Figure 6 - External DC Supply Only
3 Getting Started 323.3.3.2 External DC Supply and AC Supply To give redundancy through the use of mains and DC supply. Figure 7 - External DC Supply and AC Supply 3.3.3.3 External DC Supply and Redundant AC Supply To guard against mains failure, and failure of the DC output of single PTP 300/500/600 PIDU Plus. Figure 8 - External DC Supply and Redundant AC Supply
3 Getting Started 333.3.4 Remote LEDs and Recovery Switch The PTP 300/500/600 Series Bridge PIDU Plus provides a facility to connect remote LEDs and Recovery switch allowing the PIDU Plus to be mounted inside an enclosure. At the left hand end of the PIDU Plus under the ODU connection cover can be found a PCB header and three jumpers. Jumpers J906 and J907 should be removed and connection to the remote LEDs and Recovery switch made to J908 as shown in Figure 9. Figure 9 - Remote LED and Recovery Switch Wiring 3.3.5 Cables and connectors The cable used to connect the PTP 300/500/600 Series Bridge PIDU Plus to the ODU can be any standard CAT5e type provided that it is suitable for outdoor deployment. Motorola recommends that cables to the specification below be used: Cable: Superior Essex BBDGE CAT 5e Connector Type: Tyco, 5-569278 Gland: Motorola WB1811 CAUTION: Failure to use the recommended (or equivalent) standard of cable may invalidate the system’s safety certification. The cable used to connect the PTP 500 Series Bridge PIDU Plus to the users Network Equipment can be any standard CAT5e Cable.
3 Getting Started 34The 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 with nearby lightning strikes. If lightning activity is common in the area of deployment, the use of screened 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 swapping allowing connection to networking equipment that require cross-over cables (MDI-X networks) or straight-through cables (MDI Networks). 3.3.6 PTP and Lightning Protection The PTP 500 Series Bridge PIDU Plus meets the low level static discharge specifications identified in Section 17 “Specifications”, but does not provide lightning or surge suppression. Installations will generally require lightning or surge suppression; a separate Ethernet surge suppressor must be used and appropriately earthed. Suitable surge suppressors can be sourced from your Motorola Point-to-Point Distributor or Solutions Provider. See Section 11 “Lightning Protection”. 3.3.7 Mounting Brackets The PTP 500 Series Bridge is supplied with a mounting bracket suitable for mounting the ODU to 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 split allowing the pole mount section of the bracket to be mounted to the pole first. This allows the installer 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 the cables dressed to a cable channel. Wall mounting is achieved by screwing through the mounting lugs on either side of the unit. Remember to leave space for access to the Recovery button. See Section 3.3.2 “PIDU Plus – PTP 300/500/600 Series Bridge”.
3 Getting Started 353.3.8 Configuration and Management Configuration and Management of the PTP 500 Series Bridge is implemented using an inbuilt web server hosting a number of Configuration and Management web pages. This approach allows Configuration and Management to be carried out on any standard web browsing technology. The PTP 500 Series Bridge can also be managed remotely using the SNMP management protocol. Connection to the bridge is via the Ethernet connection carrying the bridge network traffic. Connection to the unit is via a preset IP address. This address can be changed via the Network Interface Configuration web page. A full explanation of the available web pages and their use can be found in Section 8 “Web Page Reference”. 3.4 Warranty Motorola’s standard hardware warranty is for one (1) year from purchase.

4 Product Architecture 364 Product Architecture The PTP 500 Series Bridge consists of an identical pair of units deployed one at each end of the link. The radio link operates on a single frequency channel in each direction using Time Division Duplex (TDD). One unit is deployed as a master and the other as a slave. The master unit takes responsibility for controlling the link in both directions. This product features Multiple-Input Multiple-Output (MIMO) technology as well as Orthogonal Frequency Division Multiplexing (OFDM) modulation, hence enabling a robust link to be achieved in a non-line-of-sight (NLOS) environment. 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) • USA/Canada UNII Band (5.470-5.725GHz) • ETSI 5.8 GHz band C (5.725-5.875 GHz) • USA/Canada 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 an optimal fashion using a combination of Transmit Power Control (TPC), Spectrum Management functionality and Antenna beam shape. In order to maintain link availability, the product employs adaptive modulation techniques that dynamically switches to a more robust modulation mode in severe or adverse conditions. The PTP 500 Series provides wireless Ethernet bridging between two fixed locations. To be more precise, it forwards Ethernet frames as a two-port transparent heterogeneous encapsulation bridge, meaning that each bridge forwards frames between two dissimilar interfaces (Ethernet and wireless), encapsulating Ethernet MAC frames and fragments of de-prioritised Ethernet MAC frames within PTP MAC frames for transmission at the wireless interface. A link consisting of a pair of back to back bridges appears to the data network as a standard two-port Ethernet bridge.
4 Product Architecture 37The PTP 500 series provides eight traffic classes, classifying Ethernet frames into one of eight prioritised queues based on inspection of the user priority field (802.1p) in a customer (IEEE802.1Q) VLAN tag or provider (IEEE802.1ad) VLAN tag. Untagged frames receive a default priority. The scheduling method is strict priority. The bridge does not implement any VLAN functions for bridged frames apart from inspection of the priority field, and consequently the bridge forwards tagged and untagged Ethernet frames 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 protocol stack with virtual point of attachment at the Ethernet interface. This is illustrated in Figure 10. Figure 10 – PTP 500 Series Bridge Layer Diagram Each unit in the link is manageable through an IP connection. Standard IP protocols are utilized for all management functions e.g., HP, SNMP, etc. The unit can be configured to use VLAN tags on the management interfaces.
4 Product Architecture 38The PTP 500 Series Bridge is fully software upgradeable. New software images are first downloaded from the Motorola website http://www.motorola.com/ptp to a convenient computer. The image 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 the compressed image transfer has completed successfully the image is decompressed and written to flash memory. On completion of this process the unit can be rebooted to use the newly uploaded image. Should this process fail, the unit will revert to a protected compressed image installed during manufacturing to allow the unit to be recovered.
5 General Considerations 395 General Considerations 5.1 Spectrum Planning The PTP 500 Series Bridge has two frequency variants in its product range. Variant Definition Frequency Coverage Variable Channel Width Channel Raster PTP 54500 ETSI 5 GHz Band B FCC UNII Band 5470-5725 MHz 5, 10, 15 MHz 5 MHz PTP 58500 ETSI Band, FCC ISM Band 5725-5875 MHz (ETSI) and 5725-5850 MHz (FCC) 5, 10, 15 MHz 5 MHz Table 5 - PTP 500 Series Bridge Frequency Variants NOTE: For PTP 54500 and PTP 58500, 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 Dynamic Frequency Selection). This mode uses the PTP 500 Series Bridge ability to measure the interference levels in all channels to build up a picture of the interference / noise levels in all channels. The PTP 500 Series Bridge uses statistical techniques to select the most appropriate transmit and receive channels. The i-DFS mode can be influenced in its channel decision process by selectively barring channels from use. The use of this functionality is described in detail in Section 8.3.7 “Spectrum Management”. • Second, when detailed control of the spectrum allocation is required, it is recommended that the fixed frequency mode is used to statically allocate transmit and receive channels. WARNING:This approach must not be used when Radar Detection is enabled.
5 General Considerations 405.2 Licenses and Region Codes The PTP 500 Series Bridge uses a system of Region Codes to control the operation of the radio link. The Region Code is set by a License Key. CAUTION To meet the regulatory requirements of your region you should set the correct Region Code by obtaining a new License Key from your reseller or distributor.

5 General Considerations 43To address the primary aims the Spectrum Management algorithm implements a radar detection function which looks for impulsive interference on the Operating channel only. If impulsive interference is detected Spectrum Management will mark the current Operating channel as having detected radar (Unavailable channel) and initiate a channel hop to an available channel. The previous Operating channel will remain in the Unavailable for thirty minutes after the last impulsive interference pulse was detected. After the thirty minutes have expired the channel will be returned to the Usable channel pool. The equipment can only transmit on Available channels of which there are none at initial power up. The radar detection algorithm will always scan a Usable channel for 60 seconds for radar interference before making the channel an Available channel. This compulsory channel scan will mean that there is a 60 seconds service outage every time radar is detected and that the installation time is extended by 60 seconds even 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 unit by 60 seconds. To address the “provide aggregate uniform loading of the spectrum across all devices” requirement, the channel selection algorithm will choose a channel at random from a list of available channels. The channel selection algorithm is initiated at link initialization and when radar interference is detected. 5.3.2 5.8GHz Restrictions 5.3.2.1 RTTT Avoidance and Other Channel Use Restrictions Where regulatory restrictions apply to certain channels these channels are barred. The user should note that the number of channels barred is dependant on the channel raster selected. For example see the effect of the UK RTTT channel restrictions in Figure 11, where blocks in red indicate channels that are barred. Barred channels are indicated by a “No Entry” symbol displayed on the “Spectrum Management” web page, see Section 8.3.9 “Spectrum Management Control - With Operational Restrictions”.
5 General Considerations 44 Figure 11 - 5.8 GHz UK RTTT Channel Avoidance – 15 MHz Channel Bandwidth Only 5.3.2.2 Radar Avoidance, i-DFS and Bandwidth Operation Radar avoidance at 5.8 GHz is applicable to EU operation and the requirements are currently as defined in EN 302 502 v1.1.1. 5.4 Channel Bandwidth Operation Channel bandwidths of 5, 10 and 15 MHz is supported for the PTP 500 product. Configuration of the variable bandwidth operation must be symmetric, that is, the transmit and receive channels must use identical channel bandwidths.
5 General Considerations 45 5.5 PTP 54500 Specific Frequency Planning Considerations Adjustment of the lower centre frequency allows the operator to slide the available frequency settings up and down the 5.4 GHz band. See Figure 12 (15 MHz channel bandwidth shown). Figure 12 - 5.4 GHz Available Spectrum Settings - 15 MHz Channel Bandwidth 5.5.1 PTP 54500 Raster Considerations: The PTP 54500 variant operates on a 5 MHz channel raster. See Figure 12. 5.5.2 Transmit Power Reduction at the Band Edges The PTP 54500 product variant does not apply any band edge power reduction. Check
5 General Considerations 465.6 PTP 58500 Specific Frequency Planning Considerations Adjustment of the lower center frequency allows the operator to slide the available frequency settings up and down the 5.8 GHz bands. Figure 13 shows the available spectrum (15 MHz channel bandwidth shown). Figure 13 - 5.8 GHz Available Spectrum Settings – 15 MHz Channel Bandwidth 5.6.1 PTP 58500 Raster Considerations The PTP 58500 variant operates on a 5 MHz channel raster, see Figure 13.
5 General Considerations 475.6.2 PTP 58500 Transmit Power Reduction at the Band Edges Operation 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 at the edge channels. The amount of reduction, if any, is dependant on the region code of the region of operation. This currently only affects systems configured for with Region Code 1. The maximum powers at the edge channels for 5 MHz, 10 MHz and 15 MHz are presented in Table 8 (FCC). DLCF in the table denotes the default lower center frequency.

5 General Considerations 485.7 Distance The PTP 500 Series Bridge will operate at ranges from 100 m (330 ft) to 250 km (155 miles). Operation of the system will depend on obstacles in the path between the units. Operation at 40 km (25 miles) or above will require a near line-of-sight path. Operation at 100m (330 ft) could be achieved with one unit totally obscured from the other unit, but with the penalty of transmitting at higher power in a non-optimal direction, thereby increasing interference in the band. This subject is covered in more detail in Section 6.1.3 “Path Loss Considerations“. 5.8 Networking Information The PTP 500 Series Bridge operates as a transparent Ethernet bridge. Although each unit requires an IP address, this IP address is for management purposes only, and it plays no part in the forwarding of bridged Ethernet frames. IP addresses are assigned during initial configuration as described in 7.2 “Installation Procedure”. 5.9 Lightning Protection and Regulations The amount of lightning protection is dependent on regulatory requirements and the end user requirements. The standard ODU for the PTP 500 Series Bridge is fitted with surge limiting circuits and other features to minimize the risk of damage due to nearby lightning strikes. These standard features may require some additional equipment to be configured as part of the system installation to be fully effective. CAUTION: Motorola recommends the use of screened cable and Lightning Protection units to protect connected equipment from nearby strikes. NOTE: The PTP 500 Series Bridge is not designed to survive direct lightning strikes. For this reason the unit should not be installed as the highest point in a localized area, unless specific precautions are taken. See Section 11 “Lightning Protection”. 5.10 Electrical Requirements The PTP 500 Series Bridge requires one mains supply outlet at each end of the link to plug in the PIDU Plus units. See Section 3.3.2 “PIDU Plus – PTP 300/500/600 Series Bridge”.
6 Site Planning 496 Site Planning 6.1 Site Selection Criteria The following are guidelines for selecting the installation location of the ODU and PIDU Plus for a PTP 500 Series Bridge. 6.1.1 ODU Site Selection When 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 • As high as practically possible over obstructions • Point it at the Remote end • Aesthetics and planning permission issues • Distance from the ODU and connected Network equipment (Maximum cable run from the ODU to the connected equipment is 100m [330 ft]) 6.1.2 PTP 500 Series Bridge PIDU Plus Site Selection When 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 Site Planning 506.1.3 Path Loss Considerations The path loss is the amount of attenuation the radio signal undergoes between the two ends of the link. 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 to allow for possible fading of the radio signal (Fade Margin). capabilityseasonalfadeexcessspacefree LLLLL<+++_ Where spacefreeL_ Free Space Path Loss (dB) excessL Excess Path Loss (dB) fadeL Fade Margin Required (dB) seasonalL Seasonal Fading (dB) capabilityL Equipment Capability (dB) Equation 1 - Path Loss 6.1.4 Definitions The equipment capability is given in Table 9, Table 11 (IP Mode) and Table 10, Table 12 (TDM Mode). Each table gives Link Loss, Output Power and System Thresholds for PTP 500 Series Bridge in all modulation modes. Adaptive Modulation will ensure that the highest throughput that can be achieved instantaneously will be obtained taking account of propagation and interference. The calculation of Equation 1 needs to be performed to judge whether a particular link can be installed. When the link has been installed, web pages provide information about the link loss currently measured by the equipment, both instantaneously and averaged. The averaged value will require maximum seasonal fading to be added, and then the radio reliability of the link can be computed. For minimum error rates on TDM links the maximum modulation mode should be limited to 64QAM and channel coding rate of R= 0.75, denoted as 64QAM 0.75.
6 Site Planning 51The values for (BPSK) are static receive sensitivity measurements. The other values are static receive sensitivity measurements with an AMOD threshold applied. The AMOD threshold applied is for a benign radio channel. Sensitivity: Sensitivity is defined as the combined receive input signal level on both horizontal and vertical inputs that produces a Null BER Error ratio of 3x10-7. Output Power: The output power is for a centre channel in Region 1. The output power will be reduced 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 both horizontal and vertical inputs that results in the link consistently entering the receive modulation mode under consideration as the signal level is increased. System Threshold: Thresholds for all modes except BPSK are for the relevant link optimization AMOD thresholds. System threshold for BPSK is the BPSK receive sensitivity. Maximum Link Loss: The maximum link loss for each modulation mode is derived from the AMOD threshold for that mode (sensitivity threshold for BPSK) and the maximum Region 1 centre channel output power. The figures assume integral antennas with 23 dBi (5.8 GHz and 5.4 GHz) gain are used.

Step 2: Mate the unit to the bracket together and tighten the nut and bolt. Pole diameters of 25mm (1”) to 50mm (2”) can be accommodated by inverting the back of the bracket as shown in Figure 14. Figure 14 - Mounting to pole diameters 25mm (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.
7 Installation 59The enclosure and mounting brackets of the PTP 500 Series Bridge product range are capable of withstanding wind speeds up to 200 mph (320 kph). The installer should ensure that the structure the bridge is fixed to is also capable of withstanding the prevalent wind speeds and loads. See Section 12 “Wind Loading”. WARNING: The integral safety loop should be used both for hoisting the ODU up a mast or building and into position, and also as a fixing point to secure a permanent safety lanyard from the tower/building to the ODU in case of mounting failure. Figure 15 - Integral Safety Loop The length of the safety lanyard must not exceed 1m (approx 3 ft) in length. The lanyard should be 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 mounting system for the ODU.
7 Installation 607.7 Connecting Up 7.7.1 Preparing the PIDU Plus To ODU Cable NOTE: The maximum cable length between the ODU and the user’s Network Equipment is 100m (330 ft). The cable should be assembled as shown in Figure 16: Figure 16 - Correct Cable Preparation for the Recommended Cable CAUTION: Check that the crimp tool matches the RJ45 connector being used.
7 Installation 61Both ends of the ODU cable are terminated in the same way. The above procedure should be repeated for the PIDU Plus end of the cable when the cable routing process is complete. This assumes that the installation uses PTP LPUs. If not, then the PIDU Plus end of the cable does not require a Gland, but just the RJ45. NOTE: The PIDU Plus end of the cable does not employ a cable gland. Figure 17 shows a completed ODU to PIDU Plus cable. Figure 17 - Completed ODU Connector CAUTION: Do not over tighten the glands as the internal seal and structure may be damaged. See Figure 18 for an example of an over tightened cable gland. Figure 18 - Warning Not To Over tighten Cable Gland
7 Installation 627.7.2 Making the Connections at the ODU Looking at the back of the unit with the cable entry at the bottom, the PTP 500 Series Bridge PIDU Plus connection is the first hole on the right (Figure 19) and is labeled “PIDU +”. Figure 19 – PTP 500 Series Bridge PIDU Plus Connexion
7 Installation 637.7.3 Making the PTP 300/500/600 Series Bridge PIDU Plus Connection At The ODU The following procedure describes how connection is made at the ODU. It is often easier to carry out this procedure on the ground or a suitable surface prior to mounting the ODU. Ensure that no power is connected to the PIDU Plus or present on the cable before connecting the ODU. Step 1: Assemble the cable as described in 7.7.1 above Step 2: Insert the RJ45 connector making sure that the locking tab snaps home Step 3: Screw in the body of the weather proofing gland and tighten Step 4: Screw on the clamping nut and tighten (Do not over tighten – see Figure 18) Figure 20 - Connecting the PIDU+ to the ODU Should it be necessary to disconnect the PIDU Plus to ODU cable at the ODU, this can be achieved by removing the weather proofing gland and depressing the RJ45 locking tab with a small screwdriver as shown below.
7 Installation 64 Figure 21 - Disconnecting the ODU CAUTION: Ensure that power is removed from the system at the PIDU Plus to prevent damage to the ODU while making or breaking the connection. 7.7.4 Routing the Cable After connecting the cable to the ODU it can be routed and secured using standard cable routing and securing techniques. When the cable is in place it can then be cut to the desired length at the PIDU Plus prior to connection to the PIDU Plus. 7.7.5 Fitting a Lightning Protection Unit If you have opted to fit a Lightning Protection unit, this should be installed by following the manufacturer’s instruction. For recommended types see Section 11 “Lightning Protection”.
7 Installation 657.7.6 Grounding the Installation CAUTION: The Outdoor Unit (ODU) must be properly grounded to protect against power surges. It is the user’s responsibility to install the equipment in accordance with Section 810 of the National Electric Code, ANSI/NFPA No.70-1984 or Section 54 of the National Electrical Code in the country of installation. These codes describe correct installation procedures for grounding the outdoor unit, mast, lead-in wire and discharge unit, size of grounding conductors and connection requirements for grounding electrodes. It is recommended that installation of the outdoor unit be contracted to a professional installer. 7.7.7 Making the ODU Connection at the PTP 300/500/600 Series Bridge PIDU Plus The ODU is connected to the PIDU Plus by means of a concealed RJ45 connector. The RJ45 connection has been placed inside the PIDU Plus hinged cover to prevent the user from inadvertently plugging other equipment into the ODU RJ45 socket. CAUTION: Plugging other equipment into the ODU RJ45 socket may damage the equipment due to the non-standard techniques employed to inject DC power into the 100BaseT connection between the PIDU Plus and the ODU. Plugging the ODU into other equipment may damage the ODU and/or the other equipment. Step 1: Undo the retaining screw and hinge back the cover. Step 2: Plug in the ODU into the PIDU Plus Cable ensuring that it snaps home Step 3: Replace the cover and secure with the retaining screw
7 Installation 667.7.8 Making the Network Connection at The PIDU Plus – PTP 500 Series Bridge The Network connection is made by connecting the user’s Network Equipment directly to the PIDU Plus LAN port as shown in Figure 22. Figure 22 - Making the Network Connection at the PIDU Plus 7.7.9 Mounting the PTP 300/500/600 Series Bridge PIDU Plus This step is optional. Motorola recommends that you mount the PIDU Plus on a wall or other suitable mounting surface. This prevents the unit from being knocked or kicked and can help maintain link availability. Ensure that the Recovery switch can be accessed when mounting the unit. Step 1: Fix the PIDU Plus to the wall using the lugs provided. Step 2: Make connections as per Section 7.7.8.
7 Installation 67 CAUTION: The PIDU Plus is not waterproof and should be mounted away from sources of moisture. If mounted outdoors, the unit should be mounted in a rain proof enclosure, preferably ventilated. It is also recommended that you fit a drip loop on the PIDU Plus to ODU cable to ensure that any moisture that runs down the cable into the cabinet or enclosure cannot enter the PIDU Plus. This is shown in Figure 23. The network connection and mains cable should be treated in the same way if there is a risk that they can carry moisture to the PIDU Plus. Figure 23 – PTP 500 Series PIDU Plus Drip Loop Configuration CAUTION: It is possible for moisture to enter the cable due to damage to the outer protective layer. This moisture can track down the inside of the cable, filling up the drip loop and eventually finding its way into the PIDU Plus. To protect against this the outer protective layer of the cable can be opened up at the bottom of the drip loop to allow this moisture to escape.
7 Installation 687.7.10 Powering Up The PTP 500 Series Bridge is supplied as a pair of matched Master/Slave units. The Master unit can now be powered up and accessed using the default URL http://169.254.1.2/; the Slave unit can be accessed using http://169.254.1.1/. Prior to powering up the PTP 500 Series Bridge, a computer with web browsing capabilities should be configured with an IP address of 169.254.n.n and subnet mask of 255.255.0.0 where n is any value between 1 and 254 but excluding 1.1 or 1.2. If the default addresses of the unit 169.254.1.1/2 clashes with an address you are already using on your LAN, or you are not sure, you should set up an isolated LAN. As the LAN connection presented at the PIDU Plus has auto-sensing MDI/MDIX cross over capability, connection can be made directly 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 in the Section 8.3.4 “Install Pages”. It is recommended that this procedure be carried out on the bench before physical installation commences. Providing it is safe to do so, the installer should take the process to the point where a radio link is established before proceeding to the installation site.
7 Installation 697.7.11 Aligning the PTP 500 Series Bridge ODUs The following is a description of the steps taken to establish a radio link between the two units forming 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 with alignment. The installer should adjust the alignment of the ODU in both azimuth and elevation until highest pitch tone is achieved5. 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/A Scanning Slow broken tone Not demodulating the wanted signal Rx Power Synchronized Fast broken tone Demodulating the wanted signal. Note: During acquisition there may be cycling between Scanning and Synchronized states until the alignment is sufficient to maintain the link up. Rx Power Registered Solid tone Both Master and Slave units exchanging Radio layer MAC management messages Rx Power Table 13 - Audio indications from the ODU The 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. It should be noted that if, when in the Synchronized or Registered state, the tone varies wildly, you may be suffering from interference or a fast fading link. Installing in this situation may not give a reliable link. The cause of the problem should be investigated. 5 The pitch of the alignment tone is proportional to the received power of the wireless signals. The best results are usually achieved by making small incremental movement in angular alignment.
7 Installation 70For the ease of alignment, both Master and Slave units use the install tones in the same way but with some small behavioral differences. This allows the installer to install the Slave unit first and carry out the initial alignment with the Master unit if desired. However, due to the behavioral differences of Master and Slave units, it is recommended that the Master unit is installed first and the initial alignment carried out at the Slave unit. There is a graphical installation screen available (Section 8.3.5 “Graphical Install”) using the web interface that displays the state of the link during the alignment process (up = green, down = red). The following behavior should be noted: State Name Tone Description State Description Initialising Slow beep When first started up and from time to time, the Master unit will carry out a band scan to determine which channels are not in use. During this time, between 10 and 15 seconds, the Master unit will not transmit. During this time the installation tone on the master unit will drop back to the band scan state. Alignment of the unit should cease during this time. Radar CAC Slow beep The Master has to monitor the initially chosen channel for 60 seconds to make sure it is clear of radar signals before transmitting. If a radar is detected during any of the installation phases a further compulsory 60 seconds channel scan will take place as the master unit attempts to locate a new channel that is free of radar interference. Searching Slow broken Searching for peer PTP 500. Acquiring Fast broken tone Found a PTP 500. If it is the right one, it will move onto the Registering state providing link conditions are OK, otherwise, it will reverse to Searching. Registering Fast broken Found right PTP 500 and is performing ranging function. Link Up Solid Tone The ranging process is complete and the link is UP. Alarm Fast broken dual tone A fatal error has occurred. Table 14 - Graphical Installation Behavior
7 Installation 71In addition, it is possible to use the BNC connector on the PTP 500 Series ODU and a DVM to help with the alignment process. The BNC connector provides an analogue voltage which is proportional to the receive signal strength. To use remove the protective cap frome the case mounted BNC connector and connect a DVM.Yo may have to invert the pole for correct reading. Figure 24 shows the relationship between measured values and the receive signal strength. Figure 24 - Using DVM For Alignment When the alignment process is complete the installer MUST REMEMBER TO DISARM6 BOTH UNITS 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 rates 6 After 24 hours, the units will be disarmed automatically provided that they are armed and that the link is UP.
7 Installation 727.7.12 Additional Installation Notes According to the LINKPlanner report power settings values, some additional steps are required. These are necessary to ensure that the power levels of the installed units are not too high. Higher power levels may cause the saturation of the receivers or may cause false Radar detection (in Radar Enabled regions) which will cause a degradation of the link performance and may be responsible for a link failure. The following procedure describes the additional steps required. 1. Consult the report generated by the LINKPlanner tool and note the Receive and Transmit power recommended levels. 2. Set the local unit power equal to the 'LOCAL - Max Transmit Power setting while pointing' value from the LINKPlanner report. 3. Set the remote unit power equal to the 'REMOTE - Max Transmit Power setting while pointing' value from the LINKPlanner report. 4. Access each unit separately using a PC to reboot the units. 5. Align the units as described in the User Guide. 6. Repeat Step 2 and 3 using the values 'LOCAL - Max Transmit Power setting before disarm' and 'REMOTE - Max Transmit Power setting before disarm' , if different than the corresponding 'while pointing' values. 7. Reboot the local unit then reboot the remote unit. 8. Disarm the units. 9. After 1 hour of operation the mean value of Link Loss on the status page should be within the values given in the LINKPlanner report. Further adjustments of the power levels may be necessary. Consult the LINKPlanner report notes and adjust the powers accordingly. You will not be required to reboot the units for that to take effect.
8 Web Page Reference 73 8 Web Page Reference The web user interface has three main sections. The home page presents to the operator a high level summary of the PTP 500 Series Bridge point-to-point wireless link. The status page presents a more detailed set of system parameters describing the performance of the wireless link together with 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, for example software upgrade and configuration changes. The following subsections give a detailed usage guide for all the web user interfaces. The web pages are best viewed using a screen resolution of at least 1024 x 768 pixels on a PC using Microsoft Internet Explorer Version 6 or 77. 7 The web pages have also been tested with Firefox 2.0.0.12. Other browsers may function correctly but have not been tested.
8 Web Page Reference 74The navigation bar on the left hand side of the web page is used to move between the various management 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 will automatically display all sub options. A sample web page with the navigation menu is shown in Figure 25 when the ‘Home’ Link is highlighted as the current page. Figure 25 - Menu Navigation Bar
8 Web Page Reference 758.1 Home Page – PTP 500 Series Bridge The home page for the PTP 500 Series Bridge has been designed to display a high level summary of the status of the wireless link and associated equipment. The home page (Figure 26) normally displays four key system attributes: Wireless Link Status: The Wireless Link Status attribute displays the current status of the PTP 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 link is not established. If the link is down for an unknown reason the system administrator should first consult 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 administrator to aid the identification of the unit, network or building. Figure 26 - System Summary Page Elapsed 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, for example, 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 been set, 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 and Section 8.3.10.9 “Setting the clock” explains how to set the clock.
8 Web Page Reference 768.1.1 Home Page Alarm Display The home page is also used to display all outstanding major system alarms. Whenever system alarms are asserted, a yellow warning triangle is displayed on web page navigation bar. The warning triangle will be visible from all web pages. Clicking the warning triangle will cause the web page to jump back to the system homepage. Figure 27 shows a sample alarm screen. Figure 27 - Alarm Warning Triangle The following system alarms are defined: Region Code: The region code prohibits the wireless unit from operating outside the regulated limits. An invalid region code indicates a corrupted license key. Note that a change of state may generate an SNMP trap and/or SMTP email alert.
8 Web Page Reference 77Install Status: A non-OK value indicates that signaling was received with the wrong MAC address. Note that it is very unusual to detect this, because units with wrongly configured Target MAC Address will normally fail to establish a wireless link. However, rare circumstances may establish a partial wireless link and detect this situation. NB: A non-OK value on start-up, or a change of value 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 installation the wireless unit should be disarmed. This will increase the wireless link’s data-carrying capacity and stop the installation tone generator. The wireless link is disarmed from the ‘Installation Wizard’ see Section 8.3.4.4 “Disarm”. A change of state may generate an SNMP trap and/or SMTP email alert. Unit Out Of Calibration: The unit is out of calibration and must be returned to the factory using the RMA process for re-calibration. Note that a change of state may generate an SNMP trap and/or SMTP email alert. Incompatible Region Codes: The PTP 500 Series Bridge uses region codes to comply with local regulatory requirements governing the transmission of wireless signals in the 5.8 GHz and 5.4 GHz bands. Region codes can only be changed by obtaining a new PTP 500. Note that a change of state may generate an SNMP trap and/or SMTP email alert. Incompatible Master and Slave: A non-zero value indicates that the master and slave ends of the wireless link are different hardware products, or have different software versions. Note that it is very unusual to detect this because incompatible units will normally fail to establish a wireless link. 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 configuration mismatch. 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 wireless channel to operate on. Note that a change of state may generate an SNMP trap and/or SMTP email alert.
8 Web Page Reference 78SNTP Synchronization Failed: This warning indicates that SNTP has been enabled but that the 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 state may generate an SNMP trap and/or SMTP email alert. Wireless Link Disable Warning: This warning is displayed if the Wireless link has been administratively disabled via the SNMP Interface (see 8.3.10 “
8 Web Page Reference 79Remote Management Page”). The Wireless Interface MIB-II ifAdminStatus attribute has been set to DOWN. To enable the Ethernet interface, set the ifAdminStatus attribute to UP. Note that a change of state may generate an SNMP trap and/or SMTP email alert. Ethernet Link Disabled Warning: This warning is displayed if the Ethernet link has been administratively disabled via the SNMP Interface (see 8.3.10 “
8 Web Page Reference 80Remote Management Page”), that is, the Ethernet Interface MIB-II ifAdminStatus attribute has been set to DOWN. To enable the Ethernet interface, set the ifAdminStatus attribute to UP. Note that a change of state may generate an SNMP trap and/or SMTP email alert. Ethernet Link Status: Current status of the Ethernet link. If there are any problems with the Ethernet interface, this alarm will be asserted. This alarm will most likely be seen if the unit has no Ethernet cable plugged into its Ethernet socket. Note that a change of state may generate an SNMP trap and/or SMTP email alert.
8 Web Page Reference 818.2 Systems Status Page The status page has been designed to give the system administrator a detailed view of the operation of the 500 Series Bridge from both the wireless and network perspectives. The page is subdivided into four main categories Equipment, Wireless, Telecoms 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 logged in as system administrator). The refresh period defaults to 3600 seconds and can easily be changed to refresh at any period between 2 seconds and 3600 seconds. Pressing the ‘Update Page Refresh Period’ button causes a new page refresh period to be adopted by the system. The page refresh mechanism uses a HTML Meta refresh command. Therefore the refresh is always initiated by the local 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 roles of the units in this relationship are displayed in the page title. The master unit will always have the title ‘- Master’, and the slave will always have ‘- Slave’ appended to the ‘Systems Status’ page title. Figure 28 - Status Page
8 Web Page Reference 82The 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 the equipment on the network. The link name attribute is limited to a maximum size of 63 ASCII characters. Link Location: The link location is allocated by the system administrator and can be used as a generic scratch pad to describe the location of the equipment or any other equipment related notes. 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 (5.4 or 5.8 GHz), SSS is the System Release, XX is the major release version and YY is the minor release version. Hardware Version: The hardware version attribute contains all the combined hardware version information. The attribute is formatted as DXX-RAA.BB-Z where DXX contain the version of the digital card, AA is the major hardware version number, BB is the minor hardware version number and Z describes the antenna type which can be I (integrated) or C (connectorized). Region Code: The region code is used by the system to constrain the wireless to operate within regulatory 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 Motorola or 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 several reasons, for example commanded reboot from the system reboot web page, or a power cycle of the equipment. Ethernet Link Status: Current status of the Ethernet link. A state of ‘Up’ with a green background indicates that an Ethernet link is established. A state of ‘Down’ with a red background indicates that the Ethernet link is not established.
8 Web Page Reference 83 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 be transmitted in both directions on a signal carrier at the same time. For example, on a local area network with a technology that has full duplex transmission; one workstation can be sending data on the line while another workstation is receiving data. Half Duplex data transmission means that 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, one workstation can send data on the line and then immediately receive data on the line from the same direction in which data was just transmitted. MAC Address: MAX address of the unit. Remote IP Address: Hyperlink to the other side of the Link. The IP address of the peer link is displayed if the Link is UP, otherwise “unavailable” is displayed. Automatic Page Refresh Period in Seconds: The Status page refreshes automatically according to the setting entered here (in seconds). This attribute is only displayed when the user is logged on as System Administrator. Wireless Link Status: As the attribute name suggests it displays the current status of the 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 link is not established. Maximum Transmit Power: The maximum transmit power that the local wireless unit is permitted to use to sustain a link. Remote Maximum Transmit Power: The maximum transmit power that the remote wireless unit is permitted to use to sustain a link. Transmit Power: Transmit power histogram8 is expressed in dBm and presented as: max, mean, min, and latest. The max, min and latest are true instantaneous measurements; the mean is the mean of a set of one second means. The Transmit Power may be less than the maximum permitted Transmit Power due to the TPC (Transmit Power Control) mechanism. This mechanism adjusts Transmit Power to achieve best link performance while minimizing the interference it causes to other users of this part of the Spectrum. 8 An histogram is calculated over a one hour period. If the equipment has been running for less than one hour then the histogram is calculated over the current elapsed time. The data used to compute the histogram statistics can be downloaded in an ASCII comma separated value (CSV) format via the diagnostics CSV Download page, see Section 8.3.11.2 “Diagnostics Download”.
8 Web Page Reference 84xxxx RTRTll ggPPPReceive 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 the mean of a set of one second means. See footnote 8. Vector Error: The vector error measurement compares the received signal’s In phase / Quadrature (IQ) modulation characteristics to an ideal signal to determine the composite error vector magnitude. 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 mean is the mean of a set of one second means. The expected range for Vector Error would be approximately -2dB (NLOS link operating at sensitivity limit on BPSK 0.67) to –33dB (short LOS link running 256 QAM 0.83). See footnote 8. Link Loss: The link loss is the total attenuation of the wireless signal between the two point-to-point units. See footnote 8. The link loss calculation presented below: ++−= Where is llPxTPxRPxx RT gg , Link Loss (dB) Transmit power of the remote wireless unit (dBm) Received signal power at the local unit (dBm) Antenna gain at the remote and local units respectively (dBi)9. Equation 2 - Link Loss Transmit Data Rate: The data rate in the transmit direction, expressed in Mbps and presented as: max, mean, min, and latest in an histogram format. The max, min and latest are true instantaneous measurements; the mean is the mean of a set of one second means. See footnote 8. Expected data rates can be found in Section 14 “Data Rate Calculations”. 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 instantaneous measurements; the mean is the mean of a set of one second means. 9 The antenna gain of the 500 Series bridge (23.5 dBi) is used unless one or both of the units is a Connectorized version.
8 Web Page Reference 85 See footnote 8. Expected data rates can be found in Section 14 “Data Rate Calculations”. Link Capacity: The maximum aggregate data rate capacity available for user traffic, assuming the units have been connected using Gigabit Ethernet. The link capacity is variable and depends of 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 transmit channel. List of all the modulation modes can be found in Section 14 “Data Rate Calculations” where data rate calculations plots are given for each available modulation mode. Receive Modulation Mode: The modulation mode currently being used on the receive channel. List of all the modulation modes can be found in Section 14 “Data Rate Calculations” where data rate calculations plots are given for each available modulation mode. Receive Modulation Mode Detail: This supplies the user with information regarding the receive 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 conditions Range: The range10 between the 500 Series bridge ODUs. The range is automatically set by the PTP 500 Series during installation. 10 The PTP 500 Series Bridge displays range in km by default, if the user would prefer to display range using Miles the ‘Distance Units’ attribute should be set to imperial, see the “ ” web page Section 8.3.14.

8 Web Page Reference 878.3.1 System Configuration The configuration of the 500 Series Bridge is organized into three sections: • General configuration • LAN configuration • QoS Configuration • Save and Restore The general configuration allows modification of high level administrative (descriptive) attributes and high level wireless configuration. The LAN configuration sub menu allows the system administrator to modify the Ethernet and IP configuration of the 500 Series Bridge. The QoS configuration sub menu allows the system administrator to modify the classification of priority encoded Ethernet frames into traffic classes. The save and restore submenu allows the system administrator to backup and restore the bridge configuration. It is recommended after a unit has been successfully installed; a copy of the active configuration is taken and archived by the system administrator. 8.3.1.1 General Configuration Page The general configuration page (Figure 30) is used by the system administrator to configure the 500 Series Bridge’s high level administrative (descriptive) attributes and high level wireless configuration. Figure 30 - System Configuration Page
8 Web Page Reference 88While the majority of the system configuration is entered during installation and should never require changing, this page offers the system administrator the ability to change the basic system parameters 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 be modified using the Installation Wizard pages 8.3.4 “Install Pages”. Max Receive Modulation Mode: This is the maximum mode the unit will use as its adaptive modulation. By default the Max Receive Modulation Mode is the highest mode available. 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 to that country’s regulations11. NOTE: Why 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, such as fixed satellite links. 11 In the UK there is a legal requirement to provide a minimum of 19dB of transmit power control range. When the equipment is operating with a UK Licence Key, an additional facility is provided on the configuration page that allows the transmitted power to be reduced by 19dB compared to the maximum allowed with a simple single step control.
8 Web Page Reference 898.3.1.2 LAN Configuration Page The LAN configuration page (Figure 31) is used by the system administrator to configure the 500 Series Bridge’s LAN interface. Figure 31 - LAN Configuration Page IP Address: Internet protocol (IP) address. This address is used by the family of Internet protocols to uniquely identify this unit on a network. Subnet Mask: A subnet allows the flow of network traffic between hosts to be segregated based on a network configuration. Gateway IP Address: The IP address of a computer / router on the current network that acts as a gateway. Use VLAN For Management Interfaces: This controls use of VLAN tags at the management interfaces (WWW/SNMP/SMTP/SNTP). See Section 8.3.1.3 “LAN Configuration Page – Use VLAN For Management Interfaces”.
8 Web Page Reference 90Ethernet Auto Mdix: This enables/disables the Auto Medium Dependent Interface (MDI)/Medium Dependent Interface Crossover (MDIX) capability. Default is “Enabled”. Drop Ethernet Link On Wireless Link Down: When this option is enabled the Ethernet link is momentarily dropped when the wireless link goes down. This feature is used to indicate to the connected network equipment that this Ethernet link is no longer available, thus causing STP (Spanning Tree Protocol) to re-route packets through an alternative link. All of the above attributes are non-volatile, once set they will be used by the unit even after a power on reboot. A number of attributes, such as IP Address, Subnet Mask and Gateway IP Address and VLAN settings will require a reboot before they are used. If any of these attributes are changed a reboot screen appears asking the user to verify the reboot (Figure 32 or Figure 33). Figure 32 - Configuration Reboot Page Figure 33 - Configuration Reboot Page - Ethernet Auto Negotiation Disabled This will be followed by a pop-up dialogue box asking to confirm the action. NOTE: At this point you will lose connection to the unit. If you have just changed the IP Address you now have to reconnect to the unit using the address just set.
8 Web Page Reference 918.3.1.3 LAN Configuration Page – Use VLAN For Management Interfaces The layout of the LAN Configuration page changes if this attribute is enabled in order to allow the VLAN VID and VLAN Priority to be set, see Figure 34. The VLAN settings are applied only after the unit is rebooted. CAUTION: You must ensure that you can access the VLAN which you configure here, otherwise you will be unable to access the unit following the next reboot. CAUTION: The PTP 500 management function is only compatible with single VLAN tagged packets. Any management packet with two or more packets will be ignored. Figure 34 - VLAN Configuration Fields
8 Web Page Reference 92Use VLAN For Management Interfaces: This control can be configured with one of the following three values: • No VLAN Tagging • IEEE 802.1Q Tagged (C-Tag, Type 8100) • IEEE 802.1ad Tagged (S-Tag or B-Tag, Type 88a8) VLAN Management VID: This 802.1Q or 802.1ad VLAN ID (VID) will be included in packets generated by the management interfaces. Valid settings are in the range 0 to 4094. VLAN Management Priority: This 802.1Q or 802.1ad VLAN Priority will be included in packets generated by the management interfaces. Valid settings are in the range 0 to 7. VLAN Management VID Validation: If enabled, the management interfaces will only respond to Ethernet packets tagged with the configured Management VID; otherwise packets with any VID will be accepted. 8.3.1.4 QoS Configuration Page The QoS configuration page (Figure 35) allows the system administrator to configure the classification of priority encoded Ethernet frames into up to eight traffic classes. Figure 35 - QoS Configuration Page Priority Queue Mapping: specifies the VLAN priority flag to packet queue mapping. The higher the queue number the greater its priority.

8 Web Page Reference 95 8.3.1.5 Save and Restore Configuration File The save and restore feature of a PTP 500 Series Bridge allows the system administrator to backup the operation configuration of the wireless unit. It is recommended that this facility is used immediately after a successful PTP 500 Series Bridge installation or prior to any software upgrade. In the unlikely event that a unit has to be replaced in the field, the replacement unit can be reconfigured by simply playing back the saved configuration file. 8.3.1.5.1 Save Configuration File To save the configuration file click on the ‘Save Configuration File’ button (Figure 36) and save the configuration file (.cfg) to the hard drive of your computer12 13. Figure 36 - Save and Restore Configuration Page 12 There is a feature of Internet Explorer (all versions) that will always look at the content of any downloadable file as make an assessment whether to treat the file as an ASCII or binary file. Unfortunately the configuration file is always treated as ASCII and the browser attempts to display it instead of downloading it. Firefox (all versions) makes no such assumptions. 13 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 the MAC address and the unit IP address respectively.
8 Web Page Reference 96 Figure 37 - Save Configuration File Screen The configuration file is encoded using an ASCII encoding scheme. An example is show in Figure 38. Figure 38 – PTP 500 Example Configuration File CAUTION: The configuration file is currently restricted to a single software version and can only be restored into a wireless unit operating the software version indicated in the configuration file header.
8 Web Page Reference 978.3.1.6 Restore Configuration File The configuration file can also be used when swapping out a faulty wireless unit. If one of the wireless units is replaced on a wireless link a configuration file captured from the faulty unit can be uploaded into the new unit to speed up replacement. It should be noted that when placing a configuration file into a wireless unit with a different MAC Address the license key will not be restored and may need to be entered. This can be obtained either from the Quick Start Guide supplied with the replacement wireless unit or directly from Motorola. Note that the target MAC address at the other end needs to be changed to ensure that it is using the MAC address of the replaced unit. The restoration of configuration files can be performed using the Restore configuration tool. Using the browser button to locate the configuration file you wish to restore then click the ‘Restore Configuration File and Reboot’ button (Figure 39). The user will then be prompted to confirm the action (Figure 40) Figure 39 - Restore Configuration File Pop Up Screen
8 Web Page Reference 98 Figure 40 - Reset Configuration and Reboot Confirmation Pop-up On confirmation the PTP 500 Series Bridge will: • Upload the configuration file • Perform data integrity checking • Erase previous configuration • Apply the new configuration • Restart After the unit has restarted the entire configuration from the configuration file will now be active. Note: The IP address of the unit may have also been changed. The user can check the new IP address by reading the header of the configuration file, Figure 38. CAUTION: A reboot is always required to restore a configuration file.
8 Web Page Reference 998.3.2 Statistics Page The 500 Series bridge statistics page is designed to display some key statistics of the Ethernet Bridge and the underlying wireless performance. Figure 41 - System Statistics Wireless Tx Packets: This displays the total number of good packets the bridge has sent for transmission by the wireless interface14. Wireless Rx Packets: This displays the total number of good packets the bridge has received from the wireless interface. See footnote 14. 14 The number in between brackets displays the number of packets received since the last page refresh.

8 Web Page Reference 104 8.3.4 Install Pages These pages are used during system installation. There follows a description of the install pages along with their use during the installation configuration process. The actual installation process is 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 that they can be installed without the user supplying any configuration. Each wireless link is shipped with a quick start guide. Attached to the quick start guide is a summary of the pre-configured configuration data. Table 18 shows a sample link configuration. The values in red type have been committed to the wireless unit’s non-volatile storage. Example PTP 500 Series Configuration Data For your convenience these two units have been pre-configured as link Units. Units: ODU serial number ODU serial number 0167100000A0 016710000096 Ethernet MAC address Ethernet MAC address 00:04:56:10:00:96 00:04:56:10:00:A0 Configured as: Master Slave Target MAC address Target MAC address 00:04:56:20:00:05 00:04:56:20:00:0D License Key License Key 9eb8-c807-396c-7c3f-2819-393e-1f48-e46f c49a-e2ac-9ca7-3925-e4e2-a8cc-120d-2f5e IP Address IP Address 169.254.1.2 169.254.1.1 Table 18 – 500 Series Bridge Factory Configuration Values
8 Web Page Reference 105CAUTION: The factory default configuration is set to Region 26. Region 26 allows the 500 Series bridge a maximum transmit power of 27 dBm. If the local regulatory regime limits the maximum transmit power (EIRP) to less than 27 dBm you should obtain a new license key containing the correct region 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 Units If the installer / system administrator wishes, they may modify the default installation configuration. If only the IP addresses (network configuration) are incorrect it is recommended that the values are changed via the configuration menu (Section 8.3.1.2 “LAN Configuration Page”). If any other parameters require modification then it is recommended that the system administrator use the Installation Wizard. A detailed description of the Installation Wizard follows: The 500 Series bridge operational software requires a license key to enable the wireless bridging capability and programs region code specific parameters in to the unit. Figure 43 - License Key Data Entry
8 Web Page Reference 106A license key is programmed into each unit during production and can be found written on the Configuration Data Summary Label which is attached to the Quick Install Guide. If subsequently the 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 prompted to 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 simply type or paste the license key into the data entry box (Figure 43) and click the ‘validate license key’ button. 8.3.4.2 Internet Protocol Configuration Step 1 of the installation wizard requires the installer to enter the Internet Protocol (IP) configuration. Figure 44 - Installation Wizard Internet Protocol Configuration IP Address: Internet protocol (IP) address. This address is used by the family of Internet protocols to uniquely identify this unit on a network. Subnet Mask: A subnet allows the flow of network traffic between hosts to be segregated based on a network configuration. By organizing hosts into logical groups, subnetting can improve network security and performance.
8 Web Page Reference 107Gateway IP Address: The IP address of a computer / router on the current network that acts as a gateway. A gateway acts as an entrance / exit to packets from / to other 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 to enter the Management VLAN ID, Priority and whether to validate the VLAN ID. If the user modifies this control, a warning dialog is displayed see Figure 45. Figure 45 - VLAN Warning Once complete, click the ‘Submit Internet Protocol Configuration’ button or the ‘Next’ link.
8 Web Page Reference 108 8.3.4.3 Wireless Configuration Step 2 of the installation wizard requires the installer to enter the wireless configuration parameters. Figure 46 –PTP 58500 and PTP 54500 Variants - Installation Wizard Wireless Configuration Target MAC Address: It is the MAC Address of the peer unit that will be at the other end of the wireless link. This is used by the system to ensure the unit establishes a wireless link to the correct peer. The MAC Address can be found embedded within the serial number of the unit. The last six characters of the serial number are the last three bytes of the unit’s MAC address. NOTE: A PTP 500 Series system is shipped as a pair of units with pre-loaded correct MAC addresses. Target MAC addresses will only need to be entered if an existing unit has to be replaced in the field or the units configuration has been erased.
8 Web Page Reference 109Master 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 transmits when the peer has been identified. Link Mode Optimization: Optimizes the link behavior according to the type of traffic that will be bridged. There are two modes to choose from: IP and TDM. For both modes, the TDD structure is fixed symmetrically 16:16 (16 OFDM bursts alternately in each direction). However, the point at which a modulation mode changes for given RF conditions is more conservative in TDM Mode. In practice, this means that the link will typically stay in a lower modulation mode, but with increased tolerance to RF variability. Depending upon the link characteristic that the customer requires, this may very well be the best choice. It increases consistency of link performance and equality in each direction as a trade-off against maximum throughput. Tx Max Power: This attribute controls the maximum transmit power the unit is permitted to use when installing and executing the wireless link. The maximum setting for a particular region or country is controlled by the License Key. Platform Variant: Chooses between an integrated unit or a connectorized unit that requires an external antenna. Channel Bandwidth: Users can choose a variable channel bandwidth for the available spectrum. Values of 5 MHz, 10 MHz and 15 MHz can be selected. Link Symmetry: In fixed symmetric mode, the master spends an equal amount of time transmitting and receiving whereas in fixed asymmetric mode, the master transmit and receive times have a fixed ratio. Finally, in adaptive mode the transmit and receive periods adjust with applied load. Spectrum Management Control: Is used to configure the PTP 500 Series Bridge’s Spectrum Management features, see Section 8.3.7 “Spectrum Management” for more details. i-DFS is the abbreviation for intelligent Dynamic Frequency Selection. This feature continually monitors the spectrum 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. The frequencies may be configured symmetrically or asymmetrically.
8 Web Page Reference 110Lower Center Frequency: The software for the PTP 500 Series Bridge allows a user to optionally adjust the channel center frequencies. Changing the Lower Center Frequency attribute causes all channel center frequencies to be offset. It effectively slides the channelization up or down. See Section 5.5 “PTP 54500 Specific Frequency Planning Considerations” and Section 5.6 “PTP 58500 Specific Frequency Planning Considerations” depending on the frequency variant. CAUTION: The lower center frequency attribute must be configured to the same value for both the master and slave. Failure to do so will cause the wireless link to fail reestablishment. The only way to recover from this situation is to modify the Lower Center Frequency attribute so that they are identical on both the master and slave unit. Fixed Transmit Frequency, Fixed Receive Frequency: The software for the PTP 500 Series Bridge allows a user to optionally fix the Transmit and the Receive frequencies for a wireless link. The settings must be compatible at each end of the link. Once configured the spectrum management software will not attempt to move the wireless link to a channel with lower co or adjacent channel interference. Therefore this mode of operation is only recommended for deployments where the installer has a good understanding of the prevailing interference environment. Figure 47 shows a sample fixed frequency configuration. In the example the lower center frequency is set to its default values and the Fixed Transmit Frequency is set to 5735 MHz and the Fixed Receive Frequency is set to 5735 MHz. Care must be taken when configuring the Fixed Transmit and Receive Frequencies to ensure that both frequencies are on the same 5 MHz channel raster as the Lower Center Frequency. For example both the Fixed Transmit 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 that limits the selection of the Rx frequency based upon the setting of the Tx frequency, and that the list of options presented in the fixed Tx frequency box is limited to that raster.
8 Web Page Reference 111 Figure 47 –PTP 58500 and PTP 54500 Variants - Fixed Frequency Operation Installation Tones: Where the use of audio installation tones is not required, this control allows the installer to optionally disable the tone generator during the installation process. Once the installer is satisfied with the wireless configuration options then the “Submit Wireless Configuration” button or the “Next” link should be clicked.
8 Web Page Reference 112 Figure 48 –PTP 58500 and PTP 54500 Variants - Installation Wizard Confirm Configuration If the settings are correct and appropriate, click the “Confirm Configuration, Arm Installation and Reboot” button. The user will now be prompted to confirm the action (Figure 49). Figure 49 - Reboot Confirmation Pop Up All the attributes are committed to non-volatile memory. Immediately following the write to nonvolatile memory the unit is reset.
8 Web Page Reference 113NOTE: If you have changed the Ethernet parameters you must reconnect using the correct network and address settings. 8.3.4.4 Disarm Step 5 of the installation wizard is the disarm phase. Figure 50 –PTP 58500 and PTP 54500 Variant - Disarm Installation
8 Web Page Reference 114Once Section 8.3.4.3 “Wireless Configuration” is complete pressing the “Disarm Installation Agent” button completes the installation process15 and the audible installation tone will be switched off. If the installer wishes to modify the installation configuration then the ‘Back’ link can be used to access the installation wizard steps described above. After disarming the wireless link the user is presented with a message as shown in Figure 51. This message has been obtained when configuring the link with a Region Code where maximum power is used (Region Code of 1 and power of 27 dBm). The unit shows that the Transmit Power has been reduced to the lower operating power band. The screen presents hyperlinks to the main configuration and spectrum management pages. Figure 51 - Optional Post Disarm Configuration 2 After installation the system administrator may wish to modify the wireless units descriptive configuration (link name and link location). In addition the system administrator may wish to change the spectrum management configuration of the wireless unit, or look at the analysis of the 5.8 GHz spectrum to see if the automatic channel selection is appropriate for the system administrator’s network. 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. 15 The installation process is completed when both ends of the link are ‘disarmed’.
8 Web Page Reference 1158.3.5 Graphical Install To aid the installation of wireless links two graphical installation aids have been introduced in this 500 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 example of the installation screen is shown in Figure 52. Both the PDA and the large format installation screen have the same content and only differ in size. The PDA installation screen is 232 by 220 pixels to be compatible with the typical size of a PDA screen. Figure 52 – Graphical Installation Screen The screen displays the receive power over the last three minutes. This will allow the installer to slowly sweep the antenna during installation and monitor the variation in signal strength with angular 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 state of the wireless link is written in the top left corner of the screen. The instantaneous receive power bar also encodes the state of the wireless link using green to signify that the wireless link is up and red for all other states.
8 Web Page Reference 116For the more technically aware, the installation metric is simply the instantaneous receive power in dBm + 100. The PDA installation tool is accessed via a hidden URL http://<ip-address>/pda.cgi. It should be 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 the installation wizard. 8.3.6 Software Upgrade The 500 Series system has two software image banks; one is a fixed image which is stored in protected non-volatile memory and cannot be modified by the user. The second bank is used by the system administrator to upgrade the firmware when necessary. Figure 53 shows the main software upgrade web page. Figure 53 - Software Upgrade The ‘Fixed’ or ‘Recovery’ image is used by the System Administrator to: • Reset Ethernet configuration to default settings • Erase Configuration • Upgrade software For a full description of the Recovery image see Section 9 “Recovery Mode”.
8 Web Page Reference 117The software upgrade pages are used to update a unit’s operational software. The software image to be uploaded should be downloaded to local storage from the Motorola web site. The software image 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 53) is to use the “Browse” button to locate the software image previously downloaded to local storage from the Motorola web site. Once the image is located, the user should press the “Upload image to wireless unit” button to start the software upgrade process16. The 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 transfer and that the image is valid to run on the current platform. If there are any problems a warning screen will appear. The unit being upgraded will now display information about the build it currently has stored in the image bank and the one that’s just been uploaded. If the image is not the right one, the user has the option to go back and reload a new image. (See Figure 54) Figure 54 - Software Upgrade Image Check 16 During the software upgrade process, ensure that the remote end is upgraded first using the wireless connection and then the local end can be upgraded.
8 Web Page Reference 118The user should ensure that the correct image is shown before pressing the “Program Software Image into Non-Volatile Memory” button. Once this button has been pressed the image is stored into non-volatile memory, this process can take up to 60 seconds and must not be interrupted. CAUTION: If the upgrade process is interrupted during the erasure of the image bank, or during the reprogramming of the image bank, the image bank will be left in a corrupt state. If this occurs the software must be reloaded. All software images that are stored in non-volatile memory are protected 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 the user 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 55). The upgrade process should not be interrupted. Interruption of this process can result in a corrupt main software image, which will result in the recovery image been booted at the next reset cycle. Figure 55 - Software Download Progress Indicator Figure 56 - Software Upgrade Complete
8 Web Page Reference 119When the software image has been written to non-volatile memory Figure 56 will be displayed showing the status of the software upload. Reboot the unit by clicking the “Reboot Wireless Unit” button. You will be asked to confirm this action as shown in Figure 57. Figure 57 - Reboot Confirmation Pop Up This will reboot the unit, taking up to 120 seconds. During this time you will not be able to communicate with the unit. If you cannot communicate with the unit after 120 seconds, this could indicate a problem with the memory update process. Under these circumstances the user should enter “Recovery Mode”, see Section 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 Management Spectrum Management Selection is the PTP 500 Series Bridge feature that monitors the available wireless spectrum and directs both ends of the wireless link to operate on a channel with a minimum level of co-channel and adjacent channel interference. 8.3.7.1 Wireless Channels The PTP 500 Series Bridge operates using a set of predefined overlapping channels. There are a different number of channels, depending on the raster mode selected. Each channel occupies 15 MHz, 10 MHz or 5 MHz 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 MHz overlap to the adjacent channel.
8 Web Page Reference 120The default channelization can be modified by varying the lower center frequency attribute in the installation wizard - see Section 8.3.4.3 “Wireless Configuration”. See Section 5 “General Considerations” for more detail. 8.3.7.2 Spectrum Management Measurements Each end of the 500 Series Bridge performs a single measurement of the combined receiver input power in an inactive portion of the TDD cycle. The measurement is made with an effective bandwidth of 15 MHz, 10 MHz or 5 MHz on a single channel and includes the contribution from receiver noise. 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 measurements from each channel. It is important to note that the CAC measurement process is not altered by the channel barring process. Measurements are still collected for all channels irrespective of the number of barred channels.. 8.3.7.3 Measurement Analysis Spectrum Management uses statistical analysis to process the received peak and mean measurement. 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 of the period is the statistical analysis performed. The analysis produces three key metrics for each channel: • Peak of Means • 99.9% Percentile of the Means • Mean of Means Peak of Means is the largest mean interference measurement encountered during the quantization period. The peak of means is similar to the peak of peaks and is useful for detecting slightly longer duration spikes in the interference environment. 99.9% Percentile of the Means is the value of mean interference measurement which 99.9% of all mean measurements fall below, during the quantization period. The 99.9% percentile metric is useful for detecting short duration repetitive interference that by its very nature has a minimal effect of the mean of means.
8 Web Page Reference 121 Mean of Means is the arithmetic mean17 of the measured means during a quantization period. The mean of means is a coarse measure of signal interference and gives an indication of the average interference level measured during the quantization period. The metric is not very good at predicting intermittent interference and is included to show the spread between the mean of means, the 99.9% percentile and the peak of means. NOTE: Spectrum Management uses the 99.9% percentile as the prime interference measurement. All subsequent references to interference level refer to this percentile measurement. The display of statistical measurement on the spectrum management page always shows a statistical summary of all channel measurement. The statistical summary is controlled by the Statistics Window attribute. This attribute defaults to a value of twenty minutes, which means that the mean 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 Relationship The Spectrum Management operates in a master / slave relationship. The master is assumed to be the link master configured during installation. All Spectrum Management configuration changes MUST be performed from the master. To enforce this, the Spectrum Management web page has a 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 from the master to the slave. Any Spectrum Management configuration messages received at the slave are stored in non-volatile memory. This enables both master and slave to keep identical copies of Spectrum Management configuration data in their non-volatile memories. It is therefore possible to swap master and slave roles on an active Point-to-Point link without modifying Spectrum Management configuration. 17 The arithmetic mean is the true power mean and not the mean of the values expressed in dBm.
8 Web Page Reference 122 Figure 58 - Spectrum Management as seen from the Master Figure 59 - Spectrum Management as seen from the Slave
8 Web Page Reference 123 Note: These plots are for 15MHz operation; 5/10MHz operation is similar - the width of the vertical green bar represents the channel width Figure 58 shows an example Spectrum Management webpage as seen from the master. Figure 59 shows an example Spectrum Management webpage as seen from the slave. It should be noted that the key configuration attributes are not available on the slave web page. 8.3.7.5 Spectrum Management Configuration The following section describes the user modifiable configuration accessible from the Spectrum Management webpage. It is recommended that the default values are maintained. If the user believes that the performance of the Spectrum Management algorithm requires some modifications this should only be done after consulting your Motorola Point-to-Point distributor or one of the system field support engineers. Page Refresh Period: The page refreshes automatically according to the setting entered here (in seconds). Hopping 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 active channel. Hopping Period (not configurable): The Spectrum Management algorithm evaluates the metrics every ‘Hopping Period’ seconds (180 seconds by default) looking for a channel with lower levels of interference. If a better channel is located, Spectrum Management performs an automated channel hop. If SNMP or SMTP alerts are enabled an SNMP TRAP or an email alert is sent warning the 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 instantaneous 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 channel cannot be found the 500 Series Bridge will continue to use the current active channel. (Default –85 dBm)
8 Web Page Reference 124Asymmetric DFS: The default configuration of symmetric operation constrains the link to operate symmetrically, using the same transmit and receive channels. When in symmetric mode the slave unit will always follow the master. If the master moves to a new channel the slave will hop to the same channel. When the Point-to-Point link is configured as an asymmetric link both the master 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 bandwidth selected. 8.3.7.6 Barring Channels Channels can only be barred / unbarred by the system administrator from the master Spectrum Management web page. The barring / unbarring operations are disabled on the slave web page. If an 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 or peer channel spectrum plots on the master web page. Each bar / unbar attempt will be proceeded by a confirmation dialog. It should be noted that the channel bar will take effect immediately and is not related to the measurement quantization period. 8.3.7.7 Master and Slave Channel Spectrum Graphics Spectrum Management presents its computed statistical measurements in a graphical display on both the master and slave Spectrum Management web page. See Figure 58 for an example. The X-axis shows a stylized view of the selectable wireless channels. It is important to note that adjacent channels on the display have a 10 MHz overlap. The display separates the display of channels to help the clarity of the resultant display. The axis is labeled using the channel center frequencies in MHz.. The Y-axis shows the interference power levels from –100 to –40 dBm. The active channel (channel 1 in Figure 58) is always marked using hatched green and white lines. The width of the hatching is directly proportional the channel bandwidth spectral occupancy of the channel. The individual channel metrics are displayed using a colored bar and an ‘I’ bar.
8 Web Page Reference 125The colored bar represents the following channel state: Green Active The channel is currently in use, hosting the Point-to-Point wireless link. Orange Interference The channel has interference above the interference threshold. Blue Available The channel has an interference level below the interference threshold and is considered by the Spectrum Management algorithm suitable for hosting the Point-to-Point link. Grey Barred The system administrator has barred this channel from use. For improved visibility, an additional red ‘lock’ symbol is used to indicate that a channel is barred. Table 19 - Spectrum Management change state key The 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 bar represents the mean of means and the upper horizontal bar represents the peak of means. The vertical bar is used as a visual cue to highlight the statistical spread between the peak and the mean of the statistical distribution. 8.3.7.8 Active Channel History The active channel history is a time series display of the channels used by the PTP 500 Series Bridge over the last 25 hours. The active channel history is activated from the main Spectrum Management page using the ‘Active Channel History’ hyperlink. An example of the active channel history display is shown in Figure 60. Where there are parallel entries on the display this signifies that the wireless link occupied this channel during the measurement period. The measurement periods are one minute (from zero to sixty minutes) and twenty minutes from (60 minutes to twenty five hours). Figure 60 - Active Channel History Screen
8 Web Page Reference 1268.3.7.9 Viewing Historic Spectrum Management Metrics Spectrum Management allows the system administrator to view the results of previous measurement quantization periods. Holding down the shift key and clicking the appropriate channel on the local channel spectrum plots activates this feature. This feature is available on both the master and slave web page. Figure 61 - Spectrum Management Time Series Plot Figure 61 shows an example time series plot. A time series plot displays the previous 132 measurement quantization periods. If the PTP 500 Series Bridge has not been running for 132 quantization periods then only the number of measurement quantization periods that are available are displayed.

8 Web Page Reference 1278.3.8 Spectrum Management (Fixed Frequency) The PTP 500 Series Bridge software allows a user to optionally fix transmit and receive frequencies for a wireless link. Once configured, the spectrum management software will not attempt to move the wireless link to a channel with lower co and adjacent channel interference. Therefore this mode of operation is only recommended for deployments where the installer has a good understanding the prevailing interference environment. (See Section 8.3.4.3 “Wireless Configuration”). Care must 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 visual cues. See Figure 62. The main page title identifies the mode of operation using the “Fixed Frequency Mode” postfix and the selected channels are identified by a red capital ‘F’. Figure 62 - Spectrum Management Fixed Frequency Screen Channel barring is disabled in fixed frequency mode; it is not required as dynamic channel hopping is prohibited in this mode.
8 Web Page Reference 128Note: These plots are for 15MHz operation; 5/10MHz operation is similar - the width of the vertical green bar represents the channel width The only controls available to the master are the Statistics Window and Interference Threshold attributes. They will have no effect on the operation of the wireless link and will only effect the generation of the channel spectrum graphics. The active channel history menu is removed in this mode of operation as channel hopping is prohibited. Figure 63 - Spectrum Management Help Page (Fixed Frequency) 8.3.9 Spectrum Management Control - With Operational Restrictions When operating with Radar Avoidance enabled the following variances in operation apply: • The words “Radar Avoidance” are appended to the “Spectrum Management” title at the top of the screen. See Figure 64 and Figure 65.
8 Web Page Reference 129• The only controls available to the master are the Interference Threshold attribute. This has no effect on the operation of the wireless link and will only affect the generation of the channel spectrum graphics. See Figure 64. • Extra color coding of the interference histogram is provided. See Table 21. When operating with RTTT (Road transport and Traffic Telematics) Avoidance enabled or other regulatory restrictions on channel usage the following variances apply: • All channels marked with a ‘no entry’ symbol with their associated statistics colored black are the prohibited channels. See Figure 64 and Figure 65. These channels are never used to host the wireless link, but CAC measurements are still taken so that adjacent channel biases can be calculated correctly and so the user can see if other equipment is in use.

Orange Interference The channel has interference above the interference threshold. Blue Available The channel has an interference level below the interference threshold and is considered by the Spectrum Management algorithm suitable for hosting the Point-to-Point link. Grey Barred The system administrator has barred this channel from use. Because the low signal levels encountered when a unit is powered up in a laboratory environment prior to installation (which makes the grey of the channel bar difficult to see). An additional red ‘lock’ symbol is used to indicate that a channel is barred. Red Radar Detected Impulsive Radar Interference has been detected on this channel and the channel is Unavailable for 30 minutes. At the end of the 30 minute period a Channel Availability Check is required to demonstrate no radar signals remain on this channel before it can be used for the radio link. Region Bar Region Bar This channel has been barred from use by the local region regulator. Table 21 - Spectrum Management Change State Key With Operational Restrictions

8 Web Page Reference 1358.3.10.6 SNMP Configuration SNMP State: The SNMP state attribute controls the creation of the SNMP features. Changing the SNMP state attribute requires a mandatory reboot of the unit. Only when the SNMP state is enabled at system start-up will the SNMP processor task be created. SNMP Enabled Traps: The SNMP Enabled Traps attribute controls which SNMP Traps the unit will send. SNMP Community String: The SNMP community string acts like a password between the networks SNMP management entity and the distributed SNMP clients (500 Series bridge). Only if the community string is configured correctly on all SNMP entities can the flow of management information take place. By convention the default value is set to ‘public’. When the community string is changed the system requires a mandatory reboot before the new string or phrase is adopted. SNMP Port Number: Is the port the SNMP management agent is listening to for commands from 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 these to this IP Address. When the address is changed the system requires a mandatory reboot before the setting is adopted. SNMP Trap Version: The SNMP protocol version to use for SNMP traps. Note that a system reboot is required to activate changes to this attribute. SNMP Trap Port Number: The SNMP Trap Port Number is the port number of either the networked SNMP manager or Trap receiver. By convention the default value for the port number is 162. When the port number is changed the system requires a mandatory reboot before the setting is adopted. WiMAX Control: Enables and Disables the WiMAX (802.16) MIB. This control is only displayed when ‘Fixed Frequency’ is selected during installation.
8 Web Page Reference 136 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 administrator when there are or have been system errors. SMTP Email Alert: This attribute controls the activation of the SMTP client. SMTP Enabled Messages: The SMTP Enabled Messages attribute controls which email alerts the 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 networked SMTP 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 SMTP server. 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 send the 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 networked timeserver. The system time is used for SNMP and event logging. SNTP State: When enabled, the Remote Management web page permits the following attributes to be set: SNTP IP Address: The IP address of the networked SNTP server. SNTP Port Number: The port number of the networked SNTP server. By convention the default value for the port number is 123. SNTP Poll Interval: The period at which the SNTP client polls the server for time correction updates. Default 1 hour. If for any reason an SNTP poll fails, the client will automatically perform 3 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 allow the 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 to reflect the local daylight saving time.
8 Web Page Reference 1378.3.10.9 Setting the clock The PTP 500 Series bridge has a system clock which can be used to supply accurate date and time information in the absence of a SNTP server. The system clock is battery backed and will continue 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 66, then the Remote Management 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 minutes and seconds. Set Date: Displays the current date. The year, month and day can be set using the drop-down selection 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 Diagnostics For the PTP 500 Series, the storage of link performance histograms is set to 31 days worth of data. To optimize RAM (volatile memory) usage of a cascading histogram approach has been adopted. The data is stored for one hour at a resolution of one second. The histograms use a cascading approach to daisy chain multiple histograms together. When the first histogram 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 the amount of data to be stored. The cascading histograms are defined 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 For example, when histogram 1 fills up and starts to overflow the first minute of overflow is analyzed and the maximum, minimum and mean over that minute are computed and inserted into histogram 2. When histogram 2 fills up and starts to overflow the first hour of overflow is analyzed and the maximum, minimum and mean over that hour is computed and inserted into histogram 3. When histogram 3 starts to overflow, the overflow data is simply discarded.
8 Web Page Reference 1388.3.11.1 Diagnostic Plotter New for the PTP 500 Series is the system administration diagnostic plotter facility see Figure 69. Figure 69 - Diagnostic Plotter The diagnostic plotter allows the system administrator to view the cascading histogram data in an easily accessible graphical form. The plot always displays three traces, maximum, minimum and mean by default. The diagnostic selector allows the user to select the various categories of histogram. The histograms that are available are: • Vector Error • Rx Power • Tx Power • Signal Strength Ratio • Link Loss • Rx Data Rate • Tx Data Rate • Aggregate Data Rate The diagnostic plotter uses a novel time representation in the x-axis which compresses the timeline of the plot without sacrificing resolution.
8 Web Page Reference 139The 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 the wireless link. 8.3.11.2 Diagnostics Download The diagnostics Download page allows the system administrator to download snapshots of system diagnostics.

10 Fault Finding 150 10 Fault Finding If communication has been lost with the unit at the near end of the link then there may be a hardware fault with the wiring, network or hardware. Go to the hardware section below. If communication with the far end of the link is lost then go to the radio section below. 10.1 Hardware If there are problems suspected with the link hardware the following procedure is recommended: 10.1.1 Power Check the power LED at each end of the link. If the power lights are illuminated go to the Ethernet section below. If at either end they are not illuminated then19 check the power source. If neither is 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 the ODU is short circuit or the PSU is supplying insufficient power. The likely fault can be determined by removing the jumper (J906), found inside the removable cover of the PIDU Plus, and measuring the current taken with an ammeter placed across the 2 jumper pins. This is normally 10mA without the 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 the voltage across +55V and 0V pads inside the removable cover in the PIDU Plus. Check that the PIDU Plus is not short circuit by measuring the impedance across the Power connector. Is the led faulty? 19 The power indicator LED should be continually illuminated.
10 Fault Finding 15110.1.2 Ethernet The Ethernet LED is driven from the ODU processor and thus is capable of informing you of many conditions using different flash sequences. If the Ethernet indicator does not illuminate at all there are four possible conditions. • There is no power reaching the ODU because of a wiring fault • The ODU is faulty • The PIDU Plus is faulty • The Ethernet network side is faulty Look at the following table to check the LED response for power up, disconnect the power and reapply and note what happens. Differentiating between 1-3 and 4 can be achieved by removing the power for 1 second. Watch the Ethernet indicator for 1 minute while power is removed, if it never flashes then the problem is 1-3. Take the jumper (J905) out of the PIDU Plus and check the current taken by the ODU. This should 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 and software loaded but Ethernet connectivity has been lost between the ODU and the users connected equipment. All Ethernet connections should be rechecked.

Table 22 - Power Indoor Unit LED check chart 10.1.3 Checking your wiring If the above procedures fail to diagnose the issue you may have a wiring fault. Unplug the RJ45 from 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 23. Resistances for each pair should be within 1 ohm of each other. 3. Check the cable resistance between pins 1 & 3 at the RJ45. Check against column 3 in Table 23.
10 Fault Finding 1534. Check the cable resistance between pins 4 & 7 at the RJ45. Check against column 4 in Table 23. 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 cable lengths. 7. Ensure that there is greater than 100K ohms between pin 8 and ODU ground for all cable lengths 10.2 Radio 10.2.1 No Activity If communication over the radio link has been lost and the unit at the other end of the link can be managed on its local network, the following procedure should be adopted: If there is no wireless activity then the configuration should be checked. It is essential that the following items are correct: • 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 mis-configured at each end of the link • 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 unit is 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 channel to use. If there are no faults found in the configuration and there is absolutely no wireless signal, retry the installation procedure. If this does not work then the ODU may be faulty.
10 Fault Finding 15410.2.2 Some Activity If 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
11 Lightning Protection 155 11 Lightning Protection CAUTION: EMD (Lightning) damage is not covered under standard warranty. The recommendations in this user manual, when implemented correctly, give the user the best protection from the harmful effects of EMD. However 100% protection is neither implied nor possible. 11.1 Overview The idea of lightning protection is to protect structures, equipment and people against lightning by 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 required depends on local conditions and weather patterns and applicable local regulations. Full details of lightning protection methods and requirements can be found in the international standards IEC 61024-1 and IEC 61312-1, the U.S. National Electric Code ANSI/NFPA No. 70-1984 or section 54 of the Canadian Electric Code. 11.1.1 Lightning Protection Zones The 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 lightning strike is unusual, but the full electromagnetic field is still present. The zones are determined using the ‘rolling sphere method’, an imaginary sphere, typically 50 meter 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 sphere indicate a zone (zone B) where a direct strike is less likely. The following diagrams (Figure 92 & Figure 93) show this zoning pictorially: Equipment mounted in Zone A should be capable of carrying the full lightning current. Mounting of the ODU in Zone A is not recommended. Mounting in Zone A should only be carried out observing the rules governing installations in Zone A20 Failure to do so may put structures, equipment and life at risk. 20 Local regulations may also require the fitting of the 8 AWG ground wire referred below.
11 Lightning Protection 156Equipment mounted in Zone B should be grounded using grounding wire of at least 10 AWG. This grounding wire should be connected to a grounding rod or the building grounding system before entry in to building. The PTP 500 Series bridge ODU grounding point can be found on the bottom of the unit. The 500 Series Bridge is supplied with an appropriate grounding lug for attachment to the ODU. Figure 92 - ODU mounted in Zones A & B
11 Lightning Protection 157 Figure 93 - Showing how the use of a Finial enables the ODU to be mounted inside Zone B 11.2 Detailed Installation The recommended components for an installation protected for nearby strikes are: • Recommended cables as described in Section 3.3.5 “Cables and connectors”. • Lightning protection: Motorola PTP-LPU - 2 per link (2 Motorola Kits, part number 2978) • Grounding Stake • RJ45 screened connectors NOTE: There may be a local regulatory requirement to cross bond the CAT 5e cable at regular intervals to the mast. This may be as frequent as every 10 meters (33 feet). Figure 94 includes illustrations showing the placement of the PTP lightning protection units and the recommended components for typical Mast/Tower or Wall installations.

11 Lightning Protection 16111.3.1 Pre-Power Testing Before plugging the RJ45 from the lower LPU (or if not fitted the ODU) into the PIDU, 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. Check against column 2 in Table 23. 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 3 and 4 respectively in Table 23. 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 cable lengths. 5. Ensure that there is greater than 100K ohms between pin 8 and ODU ground for all cable lengths. CAT-5 Length (Meters) Resistance between pins 1&2, 3&6 , 4&5 and pins 7&8 (ohms) Resistance between pins 1&3 (ohms) Resistance between pins 4&7 (ohms) 0 0.8 1.0 1.6 10 2.5 2.7 3.3 20 4.2 4.4 5.0 30 5.9 6.1 6.7 40 7.6 7.8 8.4 50 9.3 9.5 10.1 60 11.0 11.2 11.8 70 12.7 12.9 13.5 80 14.4 14.6 15.2 90 16.1 16.3 16.9 100 17.8 18.0 18.6 Table 23 - Resistance Table Referenced To The RJ45 at the PIDU+
11 Lightning Protection 16211.3.2 Post-Power Testing The Correct Operation is as follows 1. Connect the RJ45 to the PIDU and apply power to the PIDU, the power LED should illuminate continuously. 2. After 30 seconds, 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 correctly, refer to the fault finding guide below: The PIDU Green power LED does not illuminate Unplug the ODU connection from the PIDU and check the power LED illumination. If the power LED still does not light then check the power source. The PIDU Green power LED flashes A flashing power LED indicates that there is a short circuit on the output of the PIDU. Check that pins 4&5 and 7&8 are not crossed with pins 1&2 and 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 activity Failure of the Ethernet 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 10/100 BaseT, when 1000 BaseT was expected It is likely there is a fault with the wiring to pins 4&5 and 7&8.
11 Lightning Protection 16311.4 Locating the Fault Having identified which of the wiring cores are likely to be connected incorrectly, the location of the faulty cable can be narrowed by disconnecting sections of the drop cable and by unplugging the 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 98. The Lid nut only needs to be slackened, do not remove. Test point P1 on the LPU PCB corresponds to pin 1 on the RJ45 etc. An indication of power on the Ethernet cable is also provided inside the LPU, LED PWR1 will illuminate in the case of the PTP500 Series, LED PWR2 should not.

12 Wind Loading 16412 Wind Loading 12.1 General Antennas and electronic equipment mounted on towers or pole mounted on buildings will subject the mounting structure to significant lateral forces when there is appreciable wind. Antennas are normally 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 Force The lateral force produced by a single 500 Series bridge (integrated or connectorized model) at different wind speeds is shown in Table 24 and Table 25.

12 Wind Loading 16512.3 Capabilities of the PTP 500 Series Bridges The structure and mounting brackets of the PTP Series systems are capable of withstanding wind speeds up to 151mph (242 kph). The installer should ensure that the structure to which the 500 Series Bridge is fixed to is also capable of withstanding the prevalent wind speeds and loads. 12.4 Wind Speed Statistics Installers are recommended to contact the national meteorological office for the country concerned to identify the likely wind speeds prevalent at the proposed location. This will enable the installer to 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 Weather Service).

13 PTP 500 Series Bridge – Connectorized Model 16613 PTP 500 Series Bridge – Connectorized Model 13.1 Scope This section details the changes and additional features relevant to the connectorized version of the PTP 500 Series products.. 13.2 Product Description 13.2.1 Hardware The Connectorized PTP 500 Series Bridge is a variant designed to provide the system integrator and installer with the ability to provide extra capability to cope with very difficult radio links compared to the PTP 500 Series Integrated model. The variant allows the use of a variety of externally mounted antennas, either Flat Plate or Dish, which have higher gains than provided by the integrated antenna that is normally used. Figure 99 – Connectorized 500 Series Bridge Outdoor Unit
13 PTP 500 Series Bridge – Connectorized Model 167 13.2.2 Antenna Choices – 5.8 GHz The integrated antenna has a gain of 23 dBi. In non-FCC regions antenna choice is not restricted but any region specific EIRP limit must be obeyed by reducing the maximum Transmit power21, see Section 5.2 “Licenses and 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 PTP 500 Series Bridge. These are approved by the FCC for use with the product and are basically constrained by the following limits: • Single/Dual Polarization Parabolic Dish Antennas – up to 37.7dBi per polarization or antenna. In FCC regions when using external antennas – cable loss between the connectorized version of the PTP 500 Series Bridge and the antenna ports must not be less than 1.2dB. When operating PTP58500 with a 5MHz channel bandwidth and with dish antennas larger than 4 foot diameter, the maximum operating power must be reduced to 24dBm (3dB reduction) to ensure meeting FCC requirements. 13.2.3 Suggested Antenna Choices – 5.4 GHz The integrated antenna has a gain of 23 dBi. External antennas from the list in Section 13.6.4 “Suggested Antennas - 5.4 GHz” can be used with the Connectorized version of the PTP 500 Series Bridge. These are approved by the FCC for use with the product and are basically constrained by the following limit: • Single/Dual Polarization Parabolic Dish Antennas – up to 34.9dBi per polarization or antenna. However, the Maximum Transmit Power must be reduced to avoid exceeding the EIRP limits21. In FCC regions when using external antennas – cable loss between the connectorized version of the 500 Series Bridge and the antenna ports must not be less than 1.2dB 21 Maximum Transmit Power Allowed = EIRP Limit – Antenna Gain + Cable Losses; set the power to the 1dB value lower than the actual value calculated.
13 PTP 500 Series Bridge – Connectorized Model 16813.3 Software/Features The connectorized variant operates in the same way as the basic 500 Series and is released initially with the feature set to the Connectorized PTP 500 Series variant. The areas where the functionality is modified are: 13.3.1 Status Page The link loss calculation presented on the Status Page of the management interface has to be modified to allow for the increased antenna gains at each end of the link. The manufacturing process of the Connectorized 500 Series Bridge configures the standard hardware of the unit for use with external antennas. The installer is prompted, as part of the installation process, to enter the 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 that the link loss calculations can be correctly computed. Figure 100 - Connectorized 500 Series bridge Status Page
13 PTP 500 Series Bridge – Connectorized Model 16913.3.2 Configuration Pages The amended Configuration web page is shown below as Figure 101. Please refer to Section 8.3.4 “Install Pages” for the definitions of the parameters Antenna Gain, Cable Loss and EIRP. Figure 101 - Connectorized 500 Series bridge ‘System Configuration’ Page
13 PTP 500 Series Bridge – Connectorized Model 17013.3.3 Installation Pages The installer is prompted to enter the Antenna Gain and Cable Loss (Connectorized PTP 500 Series Bridge to antenna) at each end of the link. The Installation Pages are shown as Figure 102 to Figure 104. Figure 102 - Connectorized PTP 500 Series Bridge ‘Installation Wizard’ Page Antenna Gain: Gain of the antenna you are connecting to the unit, see table in Section 13.6.4 “Suggested Antennas - 5.4 GHz” Cable Loss: Loss in the cable between the ODU and the antenna. NOTE: In the event that there is a significant difference in length of the antenna cables for the two antenna ports, then the average value should be entered.
13 PTP 500 Series Bridge – Connectorized Model 171Spectrum Management Control: Is used to configure the 500 Series Bridge Spectrum Management features, see Section 8.3.7 “Spectrum Management” for more details. iDFS is the abbreviation for intelligent Dynamic Frequency Selection, which continually monitors the spectrum looking for the channel with the lowest level of on channel and co-channel interference. Fixed frequency mode allows the installer to fix the Transmit and receive frequencies on the units. The frequencies may be configured symmetrically or asymmetrically. Figure 103 - Connectorized 500 Series bridge ‘Confirm Installation’ Page
13 PTP 500 Series Bridge – Connectorized Model 172EIRP: 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 operator to verify that their link configuration (Max Transmit Power, Antenna Gain and Cable Loss) do not cause the link to exceed any applicable regulatory limit. Figure 104 - Connectorized 500 Series bridge ‘Disarm Installation’ Page 13.4 Deployment Considerations The majority of radio links can be successfully deployed with the 500 Series. It should only be necessary to use external antennas where the Link Estimator indicates marginal performance for a specific link – for example when the link is heavily obscured by dense woodland on an NLOS link or extremely long LOS links (>80km or >50 miles) over water.
13 PTP 500 Series Bridge – Connectorized Model 173The external antennas can be either dual-polarization (as the integrated antenna) or two single polarized 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 diverse antennas may provide additional fade margin on very long LOS links where there is evidence of correlation of the fading characteristics on Vertical and Horizontal polarizations. Dual polarization antennas (with a gain greater than the integrated antenna) are currently only available in parabolic dish form. 13.5 Link Budget An estimate of the link budget for a specific application can be obtained by using the Motorola Systems link estimation tools. For more information see the Motorola web site. 13.6 Regulatory Issues Installations must conform to any applicable local regulations for the Equivalent Isotropic Radiated Power (EIRP). Ensuring compliance becomes more complex when the connectorized unit is used with external antennas which may be locally sourced. With higher gain external antennas fitted, the Maximum Transmit power may need to be reduced for operation in specific countries. See Section 5.2 “Licenses and Region Codes” for any EIRP restrictions that may apply in your region. In some regions, operation of the PTP 54500 products is constrained by an EIRP limit. The normal constraint is that the EIRP does not exceed 30 dBm (36 dBm for PTP 58500) for radio signals with a bandwidth of >=20 MHz. As the PTP 54500 operating bandwidth is approximately 15 MHz, then the limit is 34.8 dBm EIRP (28.8 dBm for PTP 58500). When operating with external antennas, the installer/operator has to set the maximum transmit power to ensure that the EIRP limit is not exceeded. The Set_Max_Transmit_Power is calculated as below: Set_Max_Transmit_Power = [Max_Transmit_Power] rounded down to nearest lower dB.
13 PTP 500 Series Bridge – Connectorized Model 17413.6.1 Antenna Choice (FCC and Industry Canada Regions Only) The antennas which can be deployed with the Connectorized 500 Series Bridge are shown in Section 13.6.3 “Antennas for USA / Canada – 5.8 GHz” and Section 13.6.4 “Suggested Antennas - 5.4 GHz”. For FCC and Industry Canada, the PTP500 Series Bridge has been designated to operate with the antennas listed in Section 13.6.3 “Antennas for USA / Canada – 5.8 GHz” and Section 13.6.4 “Suggested Antennas - 5.4 GHz”, and having a maximum gain of 37.7 dB (34.9 dB for PTP 54500 product variant). Antennas not included in these tables or having a gain greater than 37.7 dB (34.9 dB for PTP 54500 product variant) are strictly prohibited for use with this device. The required antenna impedance is 50 ohms. 13.6.2 Cable Losses (FCC Regions Only) The FCC approval for the product is based on tests with a cable loss between the units of approximately 1.2dB at 5.8GHz. The use of lower cable losses would result in the installation being outside the FCC rules. As an indication, 1.2dB of cable loss corresponds to the following cable lengths excluding connector losses (source: Times Microwave).

13 PTP 500 Series Bridge – Connectorized Model 18013.7 Installation The section covers the generic installation instructions for the Connectorized versions of the PTP 500 Series point-to-point wireless Ethernet bridges. The actual installation procedure will depend on antenna choice, cable choice, required antenna separation etc. 13.7.1 Antenna Choice Section 13.6.3 “Antennas for USA / Canada – 5.8 GHz” and Section 13.6.4 “Suggested Antennas - 5.4 GHz” show a wide variety of antennas that can be used with the Connectorized PTP 500 Series bridge. The main selection criteria will be the required antenna gain. The secondary criteria should be the ease of mounting and alignment. For example the Radio Waves Parabolic dishes are supplied with a mount that allows adjustment for alignment independent of the actual antenna mounting. This type of antenna is much easier to align than those that have to be rotated around the mounting pole for alignment. 13.7.2 Cables and Connectors Cables should be selected using the above criteria. However it should be noted that a cable of a type similar to LMR400 is a lot more difficult to handle and route than a cable of a type similar to LMR100. Motorola recommends the use of weatherproof connectors -- preferably, ones that come supplied 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 are N-Type Male. The connectors required at the antenna end of the antenna cables are dependant on the antenna type chosen. 13.7.3 Tools The tools required for mounting a Connectorized 500 Series bridge unit are the same as those required for an Integrated 500 Series bridge detailed in Section 7.3 “Tools Required”. The tools required for mounting the antennas are specific to the antenna chosen. The installer should refer to the antenna manufacturer’s instructions.
13 PTP 500 Series Bridge – Connectorized Model 18113.7.4 Miscellaneous supplies The 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 cables 13.7.5 Mounting the Connectorized 500 Series Bridge A Connectorized 500 Series bridge is shipped with the same bracket as supplied with an Integrated unit. Details on the use of this bracket can be found in Section 3.3.7 “Mounting Brackets”. The PTP 500 Series Bridge should be mounted in a position that gives it maximum protection from the elements, but still allows easy access 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 such a position as to minimize the cable length, keeping losses to a minimum, taking into account the minimum 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 a position as to minimize both cable runs between the unit and the antennas. It is not necessary to mount the Connectorized 500 Series Bridge at the mid point between the antennas. 13.7.6 Mounting the antennas The Antennas should be mounted according to the manufacturer’s instructions. Actual antenna position will depend on the available mounting positions and link requirements. It may be necessary to mount the antennas 20m apart or at a certain distance from the ground to get the desired results. 13.7.7 Alignment Process When aligning antennas deployed with a Connectorized 500 Series bridge unit it may not be possible to hear the alignment tone emanating from the unit. In this case it may be necessary for a second installer to assist in the operation. Alternatively, it may be possible to extend the tube on the supplied stethoscope to give a longer reach.
13 PTP 500 Series Bridge – Connectorized Model 182Tip: Fine antenna alignment can sometimes be achieved by tightening and loosening the bolts on either side of the antenna mounting bracket, rather than trying to turn the whole bracket on the mounting pole. 13.7.8 Aligning Dual Polar Antennas The process for aligning a dual polar antenna is the same as aligning an Integrated unit with an integrated antenna. This procedure is detailed in Section 7.7.11 “Aligning the PTP 500 Series Bridge ODUs”. 13.7.9 Aligning Separate Antennas When using separate antennas to achieve spatial diversity, one should be mounted with Horizontal polarization and the other with Vertical polarization. The following steps should be followed: Step 1: Mount the Antennas Step 2: Mount the connectorized version of the PTP 500 Series Bridge unit Step 3: Route and make off the ends of the Antenna cables Step 4: Connect the antenna cables at the antennas Step 5: Connect one of the antenna cables at the Connectorized version of the 500 Series bridge unit. Step 6: Connect the Connectorized 500 Series Bridge ODU to PIDU Plus cable and configure the unit as described in Section 7.7 “Connecting Up”. Step 7: Align the connected antenna using the tones as described in Section 7.7.11 “Aligning the 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 the PTP 500 Series Bridge ODUs”. Step 11: Re-connect the second antenna to the Connectorized 500 Series bridge (Note: you will notice the tone pitch increase as you re-connect the second antenna due to the additional received signal). Step 12: Use the relevant status web pages to check that you are getting the results you expect from your link planning.
13 PTP 500 Series Bridge – Connectorized Model 183Step 13: Complete the installation as detailed below. 13.7.10 Completing the Installation The installation should be completed by checking all mounting nuts bolts and screws, securing all cables and weatherproofing the installation. CAUTION: Finally tightening the antenna mountings may cause the antenna alignment to be altered, due to distortion in the mounting bracket caused by 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 other side of the bracket. 13.7.11 Antenna Cable Fixing Cables should be secured in place using cable ties, cleats or PVC tape. Care should be taken to ensure that no undue strain is placed on the connectors on both the Connectorized 500 Series bridge and the Antennas and also to ensure that the cables do not flap in the wind. Flapping cables are prone to damage and induce unwanted vibrations in the mast to which the units are attached.
13 PTP 500 Series Bridge – Connectorized Model 18413.7.12 Antenna Connection Weatherproofing Where a cable connects to an antenna or unit from above, a drip loop should be left to ensure that water is not constantly channeled towards the connector. Figure 105 - Forming a Drip Loop All joints should be weatherproofed using self-amalgamating tape. It is recommended that a layer 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 106 shows this diagrammatically for the 500 Series bridge end of the antenna cables. If the antenna manufacturer has not supplied guidance on this matter, the same technique should be employed at the antenna end of the cable. Figure 106 - Weatherproofing the Antenna Connections
13 PTP 500 Series Bridge – Connectorized Model 18513.8 Additional Lightning Protection The following guidelines should be applied in addition to those described in Section 11 ”Lightning Protection”. 13.8.1 ODU Mounted Outdoors Where the ODU is mounted outdoors and is mounted some distance from the antenna, it is advisable to add additional grounding by utilizing Andrew Assemblies (such as Andrew Type 223158 www.andrew.com) as shown in Figure 107. Figure 107- Additional Grounding When Using Connectorized Units
13 PTP 500 Series Bridge – Connectorized Model 18613.8.2 ODU Mounted Indoors Where the ODU is mounted indoors, lightning arrestors should be deployed where the antenna cables enter the building as shown in Figure 108. Figure 108 - Lightning Arrestor Mounting The lighting arrestors should be ground bonded to the building ground at the point of entry. Motorola recommends Polyphaser LSXL-ME or LSXL lighting arrestors. These should be assembled as show in Figure 109. Figure 109 - Polyphaser Assembly
14 Data Rate Calculations 18714 Data Rate Calculations To aid the calculation of data rate throughput (end to end ethernet throughput assuming 1500 octet ethernet frames), the following plots of throughput verses link range have been produced for all the PTP 500 Series modulation modes, assuming the units are connected using 100 Mbps Ethernet. Please note that only 15 MHz channel bandwidth has been considered and the plots are the same for IP or TDM modes (High priority traffic), although there is a small difference between the two modes' rates because there is fragmentation in TDM (for low priority traffic) which causes the throughput to be reduced buy approximately 1% compared to the IP mode. Aggregate data rate capacity can be calculated using four key system parameters: • Receive modulation mode • Transmit modulation mode • Range Between the two wireless units • Wireless link mode (IP or TDM) There are more than this Using these parameters the Receive and Transmit data rates can be looked up using the plots Figure 110 through Figure 122.

15 AES Encryption Upgrade 19415 AES Encryption Upgrade The Motorola PTP 500 Series bridges support link encryption using the NIST approved Advanced Encryption Standard, HFIPS-197UTH. This standard specifies AES (Rijndael) as a FIPS-approved symmetric 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 link encryption 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-bit Option 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 configuration process for both encryption variants is identical except for the selection of algorithm. The following configuration example is for a 256-bit encryption key. 15.1 Configuring Link Encryption After purchasing AES encryption for the PTP 500 Series wireless link, two new license keys will be issued, one for each end of the wireless link. The following configuration process gives a step by step guide to enabling AES link encryption on a PTP 500 Series bridge. 15.1.1 License Keys The first step when configuring link encryption is to enter the new license keys in both 500 Series wireless units. Figure 123 shows the license key data entry screen. This screen can only be accessed by the system administrator. If you do not have access to the PTP 500 Series system administration pages then please contact your designated system administrator.
15 AES Encryption Upgrade 195 Figure 123 – AES Software License Key Data Entry Configuring link encryption will necessitate a 500 Series bridge service outage. Therefore it is recommended that the configuration process be scheduled during an appropriate period of low link utilization. Motorola recommends the following process for entering new license keys and minimizing service outage: 1. Open two browsers, one for each end of the link 2. Navigate to the ‘License Key’ data entry page for each end of the link 3. Enter the license keys and click the ‘Validate license key’ button at each end of the link. This will allow the software to validate the license key prior to the system reset. (DO NOT CLICK ARE YOU SURE POPUP DIALOG) 4. When both license keys have been successfully validated confirm the reboot for both ends of the link. The software is designed to allow five seconds so that a user can command both ends of the link to reset before the wireless link drops. 5. The link will automatically re-establish.
15 AES Encryption Upgrade 19615.1.2 Encryption Mode and Key Entering the license keys only does not initialize AES link encryption. Link encryption can only be enabled via the Configuration or Installation Wizard pages. Motorola recommends that the Configuration page Figure 124 be used to configure AES link encryption. Figure 124 – AES Configuration Data Entry Page Motorola recommends the following process for entering AES link encryption configuration: 1. Open two browsers, one for each end of the link 2. Navigate to the ‘Configuration’ data entry page for each end of the link 3. At both ends of the link select the ‘AES (Rijndael)’ Encryption Algorithm required.
15 AES Encryption Upgrade 1974. At both ends of the link enter ether an 128-bit or 256-bit encryption key. Note the key consists of 32/64 case insensitive hexadecimal characters. The same Key must be entered at both ends of the link. Failure to enter the same key will cause the link to fail. 5. Submit configuration on both ends of the link, but do not reboot. 6. Reboot both ends of the link (Figure 125). The software is designed to allow five seconds so that a user can command both ends of the link to reboot before the wireless link drops. Figure 125 - Configuration Reboot Screen 15.2 Wireless Link Encryption FAQ 15.2.1 Encryption data entry fields are not available Check that the correct license key has been inserted into the unit. The current license key is displayed on the ‘License Key’ data entry page. 15.2.2 Link fails to bridge packets after enabling link encryption If the wireless link status on the status web page indicates that the link is ‘Searching’, and you can browse to the local end of the link but not to the remote end, then check that the same encryption algorithm and key have been entered at both ends of the link. Failure to enter the same algorithm and key will result in received packets not being decrypted correctly. 15.2.3 Loss of AES following downgrade When downgrading (using Recovery software image 05-01 onwards) to an earlier version of software that does not support AES, the unit will indicate that the region code is invalid. The user will be required to re-install correct software (supplied when AES key was activated) and reboot the unit.

18 FAQs 22218 FAQs Can I source and use my own PoE adaptor with the 500 Series bridge? No. The 500 Series bridge uses a non-standard PoE configuration. Failure to use the Motorola supplied Power Indoor Unit could result in equipment damage and will invalidate the safety certification and may cause a safety hazard. What is Multiple-Input Multiple-Output (MIMO)? The 500 Series bridge radiates multiple beams from the antenna - the effect of which is to significantly protect against fading and to radically increase the probability that the receiver will decode a usable signal. When the effects of MIMO are combined with those of OFDM techniques and a best in class link budget, there is a 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 without optical line-of-sight, that is, with obstructions between the antennas the transmitted signal is still able to reach the receiver and produce a good quality link. What else is special about the 500 Series bridge ? There are many special features built-in to the hardware of the 500 Series bridge. The product offers the highest system gain in its class through high sensitivity antennas for improved signal recovery. It also features a Software Defined Radio system that operates on ultra fast digital signal processors but is controlled by firmware giving the ability to download new firmware when enhancements become available. The 500 Series bridge has a built-in web server for advanced management capabilities including detailed radio signal diagnosis. In which frequency bands does the 500 Series bridge operate? The Motorola point-to-point 500 Series bridge operates in the unlicensed bands 5.4 GHz (ETSI Band B) and 5.8 GHz (ETSI Band C and FCC ISM band). This means that no license is required to operate the PTP 500 Series bridge. Why does the 500 Series bridge operate in the 5GHz band? The 5 GHz band offers the dual benefits of high data throughput and good radio propagation characteristics. The wide band of spectrum available is subdivided into several channels such that multiple systems can operate in the vicinity without causing interference to one another. Is the 500 Series bridge an 802.11a device? No, although similar, the 500 Series bridge uses different encoding and radio transmission systems from 802.11a. In areas where 802.11a systems are operating, the 500 Series bridge will detect the 802.11a radio signals and choose a clear channel away from any interference.
18 FAQs 223How much power does the 500 Series bridge transmit? At all times the 500 Series bridge operates within country / region specific regulations for radio power emissions. In addition, the 500 Series bridge uses a technique known as Transmit Power Control (TPC) to ensure that it only transmits 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 that is clear of interference. In operation 500 Series bridge continuously monitors the spectrum to ensure it is operating on the cleanest channel. How does the 500 Series bridge integrate into my data network? The 500 Series bridge acts as a transparent bridge between two segments of your network. In this sense, it can be treated like a virtual wired connection between the two buildings. The 500 Series bridge forwards 802.3 Ethernet packets destined for the other part of the network and filters packets it does not need to forward. The system is transparent to higher-level management systems such as VLANs and Spanning Tree. How does the 500 Series bridge provide security for data traffic? The 500 Series bridge has a range of security features. At installation time each link must be programmed with the serial ID of its partner. The two ends of the link will only communicate with one another, eliminating any chance of "man in the middle" attacks. Over the air security is achieved through a proprietary scrambling mechanism that cannot be disabled, spoofed or snooped by commercial tools.
