All rights reserved. http://www.motorola.com 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 band in which the system operates is ‘unlicensed’ (except from the 4.9 Ghz product) and 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 basically 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 as well as comparable regulations in other countries. This equipment generates uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to other equipment, 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 equipment and ODU. • Connect the equipment 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 400 Series 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. Footnotes to the table below 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.

202 Avoiding Hazards 2.1 Preventing Overexposure to RF Energy Caution To protect from overexposure to RF energy, install the radios for the 400 family of 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. In the case of the reflector, the distance is even more conservative because the equation used models the reflector as a point source and ignores its physical dimensions. 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/rpb and Safety Code 6. • 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.

Calculated Table 3 - Power Compliance Margins Notes: 1. The regulations cover the power averaged over a 6 minute period. 2. At 5.4GHz the product is generally to a fixed EIRP which can be achieved with the Integrated Antenna. If there are no EIRP limits, use the distance calculations for 5.7GHz. 3. At 5.7GHz, for antennas between 2ft and 6ft, alter the distance proportionally to the antenna gain.
223 Getting Started 3.1 For Your Safety WARNING: Use extreme care when installing antennas near power lines. WARNING: Use extreme care when working at heights. WARNING: The Outdoor unit (ODU) for the PTP 400 Series Bridge must be properly grounded to protect against lightning. It is the user’s responsibility to install the equipment in accordance with Section 810 of the National Electric Code, ANSI/NFPA No.70-1984 or Section 54 of the Canadian Electrical Code. These codes describe correct installation procedures for grounding the ODU, mast, lead-in wire and discharge unit, size of grounding conductors and connection requirements for grounding electrodes. It is recommended that installation of the ODU be contracted to a professional installer. WARNING: The ODU for the PTP 400 Series Bridge MUST be grounded to a Protective Earth as described in Section 7.7.5 “Grounding the Installation” of this Installation Manual and in accordance with the Local Electrical Regulations. WARNING: It is recommended that the supplied Power Indoor Plus (PIDU Plus) – PTP 400 Series is used to power the PTP 400 Series Bridge ODU. The use of other power sources may invalidate safety approval and affect your warranty. WARNING: When using alternate DC supplies (via the PIDU Plus DC in terminals as described in Section 3.3.3 ”Redundancy and Alternate Powering Configurations”), such as battery-backed DC power source, the supply MUST comply with the following requirements: • The voltage and polarity is correct and is applied to the correct terminals in the PTP 400 Series Bridge PIDU Plus • The power source is rated as SELV • The power source is rated to supply at least 1A continuously, and • 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) CAUTION: 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. CAUTION: Users and installers should note that in an emergency the mains power supply is the primary disconnect device.
23CAUTION: Safety will be compromised if external quality cables are not used for connections that will be exposed to the weather. CAUTION: Safety will be compromised if a different power supply is used than the one supplied by Motorola as part of the system. This will also invalidate your warranty. 3.2 Welcome Congratulations on the purchase of the PTP 400 Series Bridge from Motorola, Inc.

253.3 Product Description This User Manual is specifically written for the PTP 400 Series of point-to-point broadband wireless solutions. The PTP 400 Series Bridge has been developed to provide Point-to-Point data connectivity via a 4.9 GHz, 5.4 GHz or 5.8 GHz wireless Ethernet bridge operating at broadband data rates. The PTP 400 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. PIDU+NetworkEquipmentPIDU+NetworkEquipmentMainsSupplyCat 5CableBuilding 1 Building 2 Figure 1 - Typical PTP 400 Series Bridge Deployment The PTP 400 Series Bridge offers true non-line-of-sight (NLOS) operation by using a combination of Orthogonal Frequency Division Multiplex (OFDM) modulation and Multiple-In Multiple-Out (MIMO) techniques. These technologies enable the PTP 400 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 400 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.
26Each end of the link consists of: • An integrated 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. Hereafter referred to as the Power Indoor Unit Plus (PIDU Plus). • Units will normally be supplied pre-configured as a link. Power is fed into the PIDU Plus from the mains via a standard “figure of eight” mains plug. The network connection is presented to the user at the PIDU Plus via an RJ45 socket. Connection between the ODU and PIDU Plus is made using standard shielded CAT5 UV resistant cable. The spare twisted pairs of the cable are used to feed power from the PIDU Plus to the ODU.
273.3.1 The Outdoor Unit (ODU) The ODU (Figure 2) is a self-contained unit. It houses both radio and networking electronics. Also shown in Figure 2 is a Lightning protection unit, see Section 11 “Lightning Protection”. A single CAT 5 cable feeds the unit. Power is fed to the unit via the brown/brown white pair connected to pins 7 and 8 and the blue/blue white pair connected to pins 4 and 5 of the RJ45 plugs and sockets employed. It should be noted that this powering arrangement is not standard Power over Ethernet (PoE). The ODU for the PTP 400 Series Bridge should only be deployed using the supplied PTP 400 Series Bridge Power Indoor Unit (PIDU Plus). WARNING: All four power conductors MUST be connected. Figure 2 - PTP 400 Series Bridge Outdoor Unit (ODU)
283.3.2 The PIDU Plus – PTP 400 Series The PTP 400 Series Bridge PIDU Plus is used to generate the ODU supply voltage from the mains supply. The PIDU Plus also houses a status indicator driven from the ODU. Figure 3 - Power Indoor Unit (PIDU Plus) – PTP 400 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 9 for further fault finding information. The bottom of the PIDU Plus houses the Ethernet connection via RJ-45 socket, an entry point for the PIDU Plus/ODU cabling and the Recovery Switch. Figure 4 - PTP 400 Series Bridge Recovery Switch Location
29The recovery switch is used for various purposes identified in Table 5. Recovery Button Depression Action More than 20 seconds, while the unit is already powered up. This resets the configuration to factory defaults. While connecting power for more than 40 seconds after power is applied This resets to factory defaults and erases any user loaded software images leaving the factory-loaded image intact. None Power cycle by switching off at the mains. All settings remain the same. Table 5 - Reset Actions On the left side of the PIDU Plus 48V DC input and output connections can be found. These are used to power the PTP 400 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 Alternate Powering Configurations”. The DC input range is 36-60V. The ODU requires 36V to operate so care should be taken to account for voltage drop over the ODU to PIDU Plus cable. WARNING: When using alternate 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 PTP 400 Series Bridge PIDU Plus • The power source is rated as SELV • The power source is rated to supply at least 1A continuously, and • 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 400 Series Bridge PIDU Plus connects 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” The input supply range for the PTP 400 Series Bridge PIDU Plus is 100V-240V AC, 47-63Hz. Mains connection to the PTP 400 Series Bridge PIDU Plus is made using a standard “figure of eight” mains lead as shown in Figure 5.

323.3.4 Remote LEDs and Recovery Switch The PTP 400 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 end of the PIDU Plus under the ODU connection cover can be found three jumpers and a PCB header. Jumpers J906 and J907 should be removed and connection to the remote LEDs and Recovery switch made to J908 as shown in Figure 9.

Motorola recommends that cables to the specification below be used. NEC/CEC: CMR (ETL) C (ETL) 75C SUN RES OIL RES II Failure to use the recommended (or equivalent) standard of cable may invalidate the system’s safety certification. The PIDU Plus/ODU cable 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”.
33The connection between the PTP 400 Series Bridge PIDU Plus and the user’s equipment can be made using any standard CAT5 patch cable. The RJ45 Ethernet connection is presented as a piece of network equipment. However as automatic MDI/MDI-X sensing and pair swapping is employed a crossed Ethernet patch cable can be used for connection to another piece of networking equipment or directly to end user equipment. It should be noted that the PIDU Plus provides continuity between the screen on the ODU to PIDU Plus cable and screen on the PIDU Plus-User equipment cable. If continuity of the screening is desired from the ODU to the PIDU Plus to the user’s equipment, CAT5 STP cable and connectors should be used for the latter connection. CAT5 STP cable between the PIDU Plus and the user’s equipment will provide additional protection against surges induced on the Ethernet connections. 3.3.6 Surge Arrestor The PTP 400 Series Bridge PIDU Plus does not provide lightning or surge suppression. Should lightning or surge suppression be required a separate Ethernet surge suppressor should be used and appropriately earthed. Suitable surge suppressors can be sourced from your Motorola Point-to-Point Distributor or Solutions Provider. The ODU is protected by built-in surge suppression as standard. See 11 “Lightning Protection”. 3.3.7 Mounting Brackets The PTP 400 Series Bridge is supplied with a mounting bracket suitable for mounting the ODU to a pole of 25mm (1”) 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 PIDU Plus can either be desk or wall mounted. The preference is wall mounted with the cables dressed to a cable channel. Remember to leave space for access to the recovery button. See section 7.7.6.
343.3.8 Configuration and Management Configuration and Management of the PTP 400 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 400 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 date of shipment from Motorola or a Motorola Point-to-Point Distributor.

354 Product Architecture The PTP 400 Series Bridge consists of an identical pair of unit’s 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. The non-line-of-sight (NLOS) aspects of the product are provided by Multiple-Input Multiple-Output (MIMO), coupled with Orthogonal Frequency Division Multiplexing (OFDM) modulation. The PTP 400 Series Bridge has been developed to operate within a selection of frequency bands. The current product range supports: • USA 4.9 GHz National Public Safety Band (4.940-4.990 GHz) - 49400 • ETSI 5.4 GHz license exempt band B (5.470-5.725 GHz) - 54400 • ETSI 5.8 GHz license exempt band C (5.725-5.850 GHz) and the USA 5 GHz ISM band (5.725-5.850 GHz) - 58400 The PTP 400 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), Planned Frequency Allocation or Dynamic Frequency Selection (DFS) and antenna beam shape. In order to maintain link availability, the product employs adaptive modulation techniques that dynamically reduce the data rate in severe or adverse conditions. To the data network the PTP 400 Series Bridge is implemented as a learning bridge. A learning bridge builds up a picture of which addresses are connected to which port. This means that it will not bridge a packet if it knows that the destination address is connected to the same port on which the bridge saw the packet. Figure 10 illustrates the PTP 400 Series Bridge layer diagram.
36 Figure 10 - PTP 400 Series Bridge Layer Diagram The PTP 400 Series Bridge functionality has been extended to encompass the specification IEEE 802.1p. IEEE 802.1p and uses Ethernet packets extended by 4 bytes, as specified in IEEE 802.1q for VLAN tagging, to prioritize packets over the wireless interface. The PTP 400 Series Bridge will forward all VLAN tagged packets regardless of the VLAN ID value. Each unit in the link is manageable through an IP connection. Standard IP protocols are utilized for all management functions e.g. HTTP, SNMP, etc. The PTP 400 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 8.3.7 “Software Upgrade”. Once the image transfer has completed successfully the image is written to 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 image installed during manufacturing to allow the unit to be recovered.
375 General Considerations 5.1 Spectrum Planning The PTP 400 Series Bridge has three frequency variants in its product range. Band Definition Frequency Coverage Channel Width Channel Raster 4.9 GHz USA National Public Safety Band 4940-4990 MHz 10 MHz 5 MHz 5.4 GHz ETSI 5 GHz band B 5470-5725 MHz 11 MHz 12 MHz 5.8 GHz USA ISM Band / ETSI 5 GHz band C 5725-5850 MHz 11 MHz 6 MHz Table 6 - PTP 400 Series Bridge Frequency Variants 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 400 Series Bridge’s ability to measure the interference levels in all channels to build up a picture of the interference / noise levels in all channels. The PTP 400 Series Bridge uses statistical techniques to select the most appropriate transmit and receive channels. I-DFS 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 8.3.8 “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.
385.2 Region Codes The PTP 400 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. Region Code Applicable Country/Frequency Max Tx Power EIRP Limit Operational Restrictions (see section 5.3) 1 USA, Canada, Taiwan, Brazil 5.8 GHz 25dBm None Reduced TX Power at Band Edges see section 5.5.3 “Transmit Power Reduction at the Band Edges” 2 China 5.8 GHz 10dBm 33dBm 3 Australia , Hong Kong 5.8 GHz 13dBm 36dBm 4 UK 5.8 GHz 7dBm 30dBm Radar and RTTT (Road Transport and Traffic Telematics, 5795 to 5815 MHz) Avoidance Enabled 5 Singapore 5.8 GHz -3dBm 20dBm 6 Eire 5.8GHz 7dBm 30dBm 7 Norway 5.8 GHZ 25dBm 53dBm Radar Avoidance Enabled 7 5.4 GHz 25dBm None Radar Avoidance Enabled 8 5.8 GHz 25dBm None 8 5.4 GHz 25dBm None 9 ETSI 5.4 GHz 4dBm 28dBm Radar Avoidance Enabled 10 5.4 GHz 4dBm None Radar Avoidance Enabled Weather Radar (5630MHz) Avoidance 10 Australia 5.4 GHz 4dBm None DFS Enabled - Weather Radar barred 11 Korea 5.8 GHz 20dBm None Band restricted to 5725 to 5825 MHz 14 4.9 GHz 23dBm When using external antennas with a gain > 26 dBi the Tx Power must be reduced by the number of dB that 26 dbi is exceeded Table 7 - PTP 400 Series Bridge Region Code Definitions
39When shipped from the factory, units are configured as follows: • 4.9 GHz PTP 400 Series Bridge – Region Code 14 • 5.4 GHz PTP 400 Series Bridge – Region Code 9 • 5.8 GHz PTP 400 Series Bridge – Region Code 1 WARNING To meet the regulatory requirements of your region you should set the correct Region Code by obtaining a new License Key from you reseller or distributor. 5.3 Operational Restrictions 5.3.1 Radar Avoidance Radar Avoidance requires that equipment used in the region: • Detects interference from other systems and avoids co-channel operation with these systems, notably radar systems. • Provide on aggregate a uniform loading of the spectrum across all devices. To address the primary aims the Spectrum Management algorithm implements a radar detection function which looks for impulsive interference on the active channel only. If impulsive interference is detected Spectrum Management will mark the current active channel as having detected radar and initiate a channel hop to an available channel. The previous active channel will remain in the radar detected state for thirty minutes after the last impulsive interference pulse was detected. After the thirty minutes have expired the channel will be returned to the available channel pool. The radar detection algorithm will always scan the active channel for 60 seconds for radar interference before using the 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.
405.3.2 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. Barred channels are indicated by a “No Entry” symbols displayed on the “Spectrum Management” web page, see section 8.3.10 “Spectrum Management Control - With Operational Restrictions ”. 5732 5738 5744 5750 5756 5762 5768 5774 5780 5786 5792 5798 5804 5810 5816 5822 5828 5834 58405734 5740 5746 5752 5758 5764 5770 5776 5782 5788 5794 5800 5806 5812 5818 5824 5830 5836 58425736 5742 5748 5754 5760 5766 5772 5778 5784 5790 5796 5802 5808 5814 5820 5826 5832 5838 5844DefaultUK RTTT Restricted Channels (Shaded) 5732 MHz5734 MHz5736 MHzLower CentreFrequencyBand Edge5850 MHzBand Edge5725 MHz Figure 11 - 5.8 GHz UK RTTT Channel Avoidance 5.4 4.9 GHz Specific Frequency Planning Considerations The current 4.9 GHz variant does not require the operator to adjust the lower center frequency to achieve full band coverage.

See Figure 12. 5.4.2 Fixed Frequency Operation When operating in ‘Fixed Frequency’ mode (see section 8.3.5.3 “Wireless Configuration”) the operator can set the operating frequency independently in both directions to any of the center frequencies available in i-DFS mode.
415.4.3 Transmit Power Reduction at the Band Edges The 4.9 GHz variant does not apply any band edge power reduction. 5.5 5.4 GHz Specific Frequency Planning Considerations To fully utilize the 5.470 to 5.725 GHz of allocated spectrum the operator must adjust the lower center frequency attribute in the installation wizard, described in detail in 8.3.5 “Install Wizard Pages” Adjustment of the lower center frequency allows the operator to slide the available frequency settings up and down the 5.4 GHz band. See Figure 13. Figure 13 - 5.4 GHz Available Spectrum Settings 5.5.1 Raster Considerations The PTP 400 Series bridge 5.4 GHz variant operates on a 12 MHz channel raster that is set to odd center frequencies. See Figure 13. 5.5.2 Fixed Frequency Operation When operating in ‘Fixed Frequency’ mode (see section 8.3.5.3 “Wireless Configuration”) the operator can set the operating frequency independently in both directions to any of the center frequencies available in i-DFS mode using the ‘Default Raster’ setting. For the expert user further granularity can be obtained by turning off the ‘Default Raster’. In this mode the operator is able to select any odd frequency that sets the channel in-band. 5.5.3 Transmit Power Reduction at the Band Edges The 5.4 GHz variant does not apply any band edge power reduction. 5479 5491 5503 5515 5527 5539 5551 5563 5575 5587 5599 5611 5623 5635 5647 5659 5671 5683 5695 5481 5493 5505 5517 5529 5541 5553 5565 5577 5589 5601 5613 5625 5637 5649 5661 5673 5685 5697 Band Edge5470 MHzBand Edge5725 MHz DefaultAvailable Frequency Settings (MHz)5479 MHz 5481 MHz Lower Centre Frequency 5483 5495 5507 5519 5531 5543 5555 5567 5579 5591 5603 5615 5627 5639 5651 5663 5675 5687 5699 5485 5497 5509 5521 5533 5545 5557 5569 5581 5593 5605 5617 5629 5641 5653 5665 56775487 5499 5511 5523 5535 5547 5559 5571 5583 5595 5607 5619 5631 5643 5655 5667 5679 5691 5487 MHz 5483 MHz 5485 MHz 5489 5501 5513 5525 5537 5549 5561 5573 5585 5597 5609 5621 5633 5645 5657 5669 5681 5693 5689 5701 5713 5709 5707 5711 5703 5715 5705 5717 5489 MHz
425.6 5.8GHz Specific Frequency Planning Considerations To fully utilize the 5.725 to 5.850 GHz of allocated spectrum the operator must adjust the lower center frequency attribute in the installation wizard, described in detail in 8.3.5 “Install Wizard Pages” Adjustment of the lower center frequency allows the operator to slide the available frequency settings up and down the 5.8 GHz band. See Figure 14 5732 5738 5744 5750 5756 5762 5768 5774 5780 5786 5792 5798 5804 5810 5816 5822 5828 5834 58405734 5740 5746 5752 5758 5764 5770 5776 5782 5788 5794 5800 5806 5812 5818 5824 5830 5836 58425736 5742 5748 5754 5760 5766 5772 5778 5784 5790 5796 5802 5808 5814 5820 5826 5832 5838 5844Band Edge5725 MHzBand Edge5850 MHzDefaultAvailable Frequency Settings (MHz)5732 MHz5734 MHz5736 MHzLower CentreFrequencyBand Edge5850 MHzBand Edge5725 MHz Figure 14 - 5.8 GHz Available Spectrum Settings 5.6.1 Raster Considerations The PTP 400 Series Bridge 5.8 GHz variant operates on a 6 MHz channel raster that is set to even center frequencies. see Figure 14. 5.6.2 Fixed Frequency Operation When operating in ‘Fixed Frequency’ mode (see section 8.3.5.3 “Wireless Configuration”) the operator can set the operating frequency independently in both directions to any of the center frequencies available in i-DFS mode using the ‘Default Raster’ setting. For the expert user further granularity can be obtained by turning off the ‘Default Raster’. In this mode the operator is able to select any even frequency that sets the channel in-band. 5.6.3 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 400 Series Bridge reduces the power when operating at the edge channels. The amount of reduction if any is dependant on the local regulator authority of the region of operation. These currently only affect systems configured with Region Code 1. The power reduction in the edge channels is presented in Figure 15.

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 feet) 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 400 Series Bridge operates as a transparent Ethernet bridge. Each unit requires an IP address. This IP address is for management purposes only and it plays no part in the operation of the system. IP addresses are assigned during initial configuration as described in section 7.2 “Installation Procedure”. 5.9 Lightning Protection The amount of lightning protection is dependent on regulatory requirements and the end user requirements. The standard ODU for the PTP 400 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. Motorola recommends the use of screened cable and surge arrestor to protect connected equipment from nearby strikes. The PTP 400 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”.
445.10 Electrical Requirements The PTP 400 Series Bridge is supplied with a variable input voltage (90-264V, 47-63Hz AC) inline power supply unit which is incorporated into the PTP 400 Series Power Indoor Unit (PIDU Plus). The PTP 400 Series Bridge requires one mains supply outlet at each end of the link. Alternately, the PTP 400 Series Bridge may be powered by a DC supply (45-55V) though the terminals provided under the left cover on the PIDU Plus.
456 Site Planning 6.1 Site Selection Criteria The following are guidelines for selecting the installation location of the ODU and PIDU Plus for the PTP 400 Series Bridge. 6.1.1 ODU Site Selection When selecting a site for the ODU the following should be taken into consideration: • That 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 • Protection from the weather • Aesthetics and planning permission issues • Distance from the PIDU Plus and connected equipment (Maximum cable run ODU to connected equipment is 100m [330 feet]) • Distance from the PIDU Plus to the ODU (Maximum cable run from the PIDU Plus to the ODU is 100m [330 feet] minus the length of the cable from the PIDU Plus to the connected equipment) 6.1.2 PTP 400 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 reset switch (See section 3.3.2 “The Power Indoor Unit (PIDU Plus)” and section 9 “Fault Finding”
466.1.3 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 Aggregate Ethernet throughput rate versus maximum link loss The equipment capability is given in Table 8 and Table 9. It gives the Ethernet throughput rate versus link loss for the PTP 400 Series Bridge in both 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. The full calculation is relatively complicated and thus Motorola has supplied a PTP Link Estimator that calculates the radio propagation and reliability of NLOS links using the PTP 400 Series Bridge equipment.

497 Installation Motorola recommends that only qualified personnel undertake the installation of a PTP 400 Series Bridge solution. 7.1 Preparation Before proceeding with the installation you should: • Check the contents of all packages against the parts lists shown in the packing list. • Ensure that you have the correct tools for the job. • Ensure that you are qualified to undertake the work. • Ensure that you have taken the correct safety precautions. • Have completed the site planning as described in section 6 “Site Planning”. 7.2 Installation Procedure The installation procedure for a PTP 400 Series system consists of the following steps: • Mounting the ODUs, section 7.6 • Connecting up, section 7.7 • Mounting the PIDU Plus units, section 7.7.6 • Powering Up, section 7.7.9 • Aligning the ODUs, section 7.7.10 7.3 Tools Required The following specific tools are required to install the PTP 400 Series Bridge in addition to general tools: • 13mm Spanner / Wrenche • RJ45 Crimp Tool • IBM Compatible Personal Computer (PC) running Windows 98 or later with 10 or 100baseT Ethernet (Ability to change IP settings easily is recommended) • Either Internet Explorer version 6 or higher, or Mozilla Firefox v1.5 or higher are recommended. • Ethernet patch cable • 6mm general purpose crimp tool for the grounding lug (optional for lightening Protection)
507.4 Installation Support Online installation support and contact details for your regional support can be found at http://www.motorola.com/ptp A Frequently Asked Questions (FAQ) section can be found in section 16. 7.5 Legal Disclaimer IN NO EVENT SHALL MOTOROLA, INC. BE LIABLE FOR ANY INJURY TO ANY PERSONS OR ANY DAMAGE CAUSED DURING THE INSTALLATION OF THE MOTOROLA PTP 400 SERIES PRODUCT. 7.6 Mounting the ODUs The ODU mounting bracket is designed to ease installation by fixing the bracket to the pole and then bringing the ODU into position using a single bolt fixing. The ODU should be mounted using the following steps ensuring that the cable entry is at the bottom: The ODU mounting bracket is designed to work with poles with diameters in the range 50mm (2”) to 75mm (3”). Step 1: Mount the bracket to the pole. Step 2: Mate the unit to the bracket 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 16.
51 Figure 16 - Mounting to pole diameters 25mm (1”) to 50mm (2”) When adjustment is complete tighten all bolts to 14Nm (11 lb ft). Warning: Do not over tighten the bolts as bracket failure may occur. The enclosure and mounting brackets of the PTP 400 Series Bridge are capable of withstanding wind speeds up to 150mph (242kph). The installer should ensure that the structure to which the bridge is fixed is also capable of withstanding the prevalent wind speeds and loads. See Section 12 “Wind Loading”. 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 17 - Integral Safety Loop
52The 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. 7.7 Connecting Up 7.7.1 Preparing The Cable — RJ45 connections Cables should be prepared using the following instructions along with the cable and connector supplier’s instructions: Step 1: Assemble gland Step on cable as shown Step 2: Strip the outer insulation Step 3: Arrange conductors as shown in Figure 19 and cut to length Step 4: Insert conductors and crimp
53 Figure 18 - Completed ODU connector Both 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. Note: The PIDU Plus end of the cable does not employ a cable gland. Figure 19 - RJ45 Pin Connection
547.7.2 Making the 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 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 5.7.1 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 Figure 20 - Connections at the ODU
55Should 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: Figure 21 - Disconnecting the ODU Warning: Ensure that power is removed from the system at the PIDU Plus to prevent damage to the ODU while making or breaking the connection. 7.7.3 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. 7.7.4 Fitting A Surge Arrestor If you have opted to fit a Surge Arrestor, this should be installed by following the manufacturer’s instructions. For recommended types see Section 11 “Lightning Protection”
567.7.5 Grounding the Installation The Outdoor Unit (ODU) for the PTP 400 Series Bridge 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 Canadian Electrical Code or 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. See Section 11 “Lightning Protection” for recommended grounding kits. Failure to follow these Lightning Protection recommendations will invalidate your warranty if damage to the system is found to be caused by lightning. 7.7.6 Making the ODU Connection at the PTP 400 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 inadvertently plugging other equipment into the ODU RJ45 socket. Warning: 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 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 to PIDU Plus Cable ensuring that it snaps home
57 Step 3: Replace the cover and secure with the retaining screw 7.7.7 Making the Network Connection at the PIDU Plus – PTP 400 Series 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 PTP 400 Series Bridge PIDU Plus
587.7.8 Mounting the PTP 400 Series Bridge PIDU Plus 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 reset 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 7.7.6 WARNING: 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. As 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.
59Mount PIDU+ at a height that protects it from flooding or rising dampTo ODUAC MainsPower EthernetDrip LoopOptional Drain Hole Figure 23 - PTP 400 Series Bridge PIDU Plus Drip Loop Configuration WARNING: 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. WARNING: Some network operators employ gel filled cables to get around the problem of moisture ingress and transmission. The PTP 400 Series Bridge has NOT been tested using these cables. Use of gel filled cables may affect the performance of PTP 400 Series Bridges.
607.7.9 Powering Up The PTP 400 Series Bridge is supplied as a pair of matched Master/Slave units. The Master unit to be configured 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 400 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 a default configuration as a hub/switch (and auto-sensing MDI/MDIX cross over is employed) 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 8.3.5. This process will give the installer the opportunity to set the unit’s IP address to one that is in the desired address range and set each unit up with the MAC address of its peer unit ready to establish a radio link. 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. NOTE: It is possible that some units may not be accessed using the above default URL. This is because these units may have been previously configured with IP addresses 10.10.10.10 (Slave) and 10.10.10.11 (Master). Therefore, users must use the URL http://10.10.10.10/ and/or URL http://10.10.10.11/ to configure the units. Please ensure that a computer with web browsing capabilities is configured with an IP address of 10.10.10.n, where n is any value between 2 and 254 but excluding 10 and 11, to configure these units.
617.7.10 Aligning the PTP 400 Series 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 400 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 achieved13. The tones and their meanings are as follows: State Name Tone Description State Description Pitch Indication (Higher pitch = higher power) Band Scan 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 Rx Power Registered Solid tone Both Master and Slave units exchanging Radio layer MAC management messages Rx Power Table 10 - 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. For 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. 13 The pitch of the alignment tone is proportional to the power of the received wireless signals. The best results are usually achieved by making small incremental movement in angular alignment.
62The following behavior should be noted: 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 and as a consequence of this neither will the Slave unit. During this time the installation tone on the master unit will drop back to the band scan state and the Slave unit will drop back to Scanning state with the pitch of the tone set be the background noise level. Alignment of the unit should cease during this time. The master unit can take between 30 seconds in 0-5km (0-3 miles) mode to 300 seconds in 0-200km (0-124 miles) mode to determine the range of the link being installed14. The Master unit will remain in the Scanning state until the range of the link has been established. The Master unit will only move to the Synchronized state when the range of the link has been established. If at the end of the ranging period the ‘Registered’ state is not achieved due to interference or other reasons, the Master unit will retry twice more on the same channel before moving to another available channel. Should this occur it might take a number of minutes to establish a link in the ‘Registered’ state. The Slave unit does not have a ranging process. The slave unit will change to the Synchronized state as soon as the wanted signal is demodulated. When the alignment process is complete the installer MUST REMEMBER TO DISARM BOTH UNITS in the link as described in section 8.3.5. This is necessary for the following: • Turn off audible alignment aid. • Enable Adaptive Modulation • Fully enable Dynamic Frequency Selection • Clear unwanted installation information from the various systems statistics • Store the link range for fast link acquisition on link drop • Enable Higher Data Rates 14 If the unit is operating where mandatory radar avoidance algorithms are implemented the ranging behavior for the 400 Series Bridge may be affected. The Master has to monitor the initially chosen channel for 60 seconds to make sure it is clear of radar signals before transmitting. If 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.
63The units will automatically disarm after 24 hours.
648 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 400 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 administrator section. This section is password protected and allows the system administrator to perform all the day-to-day administrative procedures, e.g. software upgrades and configuration changes. The following subsections give a detailed usage guide for all the web user interfaces. All 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 615. The navigation bar on the left hand side of the web page (Figure 24) is used to move between the various management pages. Figure 24 - Menu Navigation Bar 15 The web pages have also been tested with Mozilla Firefox 1.5. Other browsers may function correctly but have not been tested.
65The currently selected page is always highlighted with a light blue background. The menu is hierarchical selecting any menu item which has associated submenu options will automatically display all sub options. 8.1 Home Page – PTP 400 Series Bridge The home page for the PTP 400 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 25) normally displays four key system attributes: Wireless Link Status: The Wireless Link Status attribute as the name suggests 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. 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 25 - PTP 400 Series Bridge Home 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, e.g. commanded reboot from the system reboot webpage, or a power cycle of the equipment. System Clock: If the SNTP (Simple Network Time Protocol) (see section 8.3.13) is enabled a system clock attribute is displayed giving the date and time of the last page refresh. If SNTP is disabled then the system clock attribute is not displayed on the home page.
668.1.1 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 the 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 home page. Figure 26 shows a sample alarm screen. Figure 26 - Alarm Warning Triangle The following major system alarms are defined: Install Arm State: The Install Arm State alarm is displayed. 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 8.3.5.
67Install Status: If any errors are detected during the installation process, the unit will automatically raise an audible alarm. The install status alarm will be raised with an appropriate reason code, e.g. the alarm will be raised if an incorrect target MAC address is specified for the peer PTP 400 Series Bridge wireless unit. ARQ Is Not Configured: ARQ must be enabled on both ends of the Point-to-Point link. This error message is generated if there is a mismatch in the ARQ settings between both ends of the link. Encryption Is Not Configured On Both Units: Encryption must be enabled on both ends of the Point-to-Point link before the over-the-air packets can be successfully decrypted. This error message is generated if encryption is not configured on both units. Ethernet Link Status: 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 not got an Ethernet cable plugged into its Ethernet socket. Master And Slave Have Incompatible Region Codes: The PTP 400 Series Bridge uses region codes to comply with local regulatory requirements governing the transmission of wireless signals. Region codes can only be changed by obtaining a new PTP 400 Series Bridge license key. If this alarm is encountered the appropriate license keys from the country of operation should be obtained from your distributor. Applying license keys containing the same region codes to both ends of the link will remove the alarm. Spectrum Management Channel Warning: The alarm warns a user when the intelligent spectrum management feature can't find a suitable wireless channel. This alarm occurs when the signal assessment features of the PTP 400 Series Bridge can’t find a channel to operate on. Ethernet Configuration Mismatch: 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. Wireless Link Disabled Warning: Wireless traffic has been disabled via the SNMP ifAdminStatus attribute. SNTP No Sync Warning: This warning indicates that SNTP has been enabled but that the unit is unable to synchronize with the specified SNTP server. Section 8.3.13 explains how to configure SNTP.
688.2 System Status Page The status page has been designed to give the system administrator a detailed view of the operation of the PTP 400 Series Bridge from both the wireless and network perspectives. The page is subdivided into three main categories Equipment, Wireless and Ethernet/Internet. The ‘Equipment’ section contains the entire unit’s inventory and identification information. The ‘Wireless’ section presents the key wireless metrics displayed as a series of measurements and histograms. 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 PTP 400 Series Bridge at this interval. Figure 27 - Status Page
69The two PTP 400 Series Bridges 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 the ‘- Slave’ appended to the ‘Systems Status’ page title. The 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 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 FFPP-XX-YY where FF is the frequency variant (4.9, 5.8 or 5.4 GHz), PP is the product variant, 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 DX.-RYY-Z where DXX contain the version of the digital card, RYY contains the version of the RF (radio frequency) card 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 the regulatory regime of the particular country. The region code is encoded in the product license key. If the operator wishes to change the region code, a new license key must be obtained from Motorola or the local 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, e.g. 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. Ethernet Speed: The negotiated speed of the Ethernet interface specified in Mbps. Ethernet Duplex: The negotiated duplex of the Ethernet interface.
70Full Duplex: 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: 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: The Medium Access Control Layer (MAC) address is used to uniquely identify the equipment on an Ethernet network. IP Address: Internet Protocol (IP) address. This address is used by the family of Internet protocols to uniquely this identify the 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. Gateway IP Address: The IP address of a computer on the current network that acts as a gateway. A gateway acts as an entrance / exit to packets from / to other networks. Wireless Link Status: As the attribute name suggests, this 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. If the link is down for an unknown reason the system administrator should first consult the status webpage for a more detailed summary of the prevailing system diagnostics. Target Receive Modulation Mode: The target modulation mode is used by the wireless subsystem to control the adaptive modulation algorithm. The mode is used by the PTP 400 Series Bridge as an upper limit. The system will not move to a high rate modulation mode even if the signal / interference environment will support high rate modes. Maximum Transmit Power: The maximum Transmit Power the local wireless unit is permitted to use to sustain a link. Remote Transmit Maximum Power: The maximum transmit power the remote wireless unit is permitted to use to sustain a link.
71Transmit Power: Transmit power histogram16 is expressed in dBm and presented as: max, mean, min, and latest. Receive Power: Receive power histogram is expressed in dBm and presented as: max, mean, min, and latest. 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 a histogram and expressed in dB and presented as: max, mean, min and latest. The expected range for Vector Error would be approximately 0dB (NLOS link operating at sensitivity limit on BPSK ½) to –29dB (short LOS link running 64QAM 7/8). Link Loss: The link loss is the total attenuation of the wireless signal between the two point-to-point units. 16 All histograms are calculated over a one hour period. If the equipment has been running for less than one hour then the histograms are 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 8.3.14 “Diagnostics”.

The antenna gain of the PTP 400 Series Bridge is used unless one or both of the units is a Connectorized version. See Section 11.3 for more details Equation 2 - Link Loss Receive Data Rate: The data rate in the receive direction, expressed in Mbps and presented as: max, mean, min, and latest histogram format. Transmit Data Rate: The data rate in the transmit direction, expressed in Mbps and presented as: max, mean, min, and latest histogram format. Receive Modulation Mode: The modulation mode currently being used on the receive channel. The number in brackets after the modulation mode and coding rate string is the effective data rate available to all MAC layer protocols. Transmit Modulation Mode: The modulation mode currently being used on the transmit channel. The number in brackets after the modulation mode and coding rate string is the effective data rate available to all MAC layer protocols. Receive Modulation Mode Detail: The receive modulation mode detail presents to the user the reason why the wireless link is not operating at the maximum capacity (modulation mode). Values that can be presented in this field are:
73• Running at maximum receive mode: The wireless link is operating at its receive maximum capacity. To confirm that the wireless link is operating at its maximum transmit capacity either look at the 'Transmit Modulation Mode' on this page or look at the peer wireless units 'Receive Modulation Mode Detail' attribute. • Running at user-configured Target Modulation Mode: This indicates that the wireless link could operate at a higher capacity but has been limited in modulation mode by the user from the configuration page. • Restricted because Installation is armed: During installation the wireless link is restricted to operate in a low order modulation mode (BPSK ½ ). Disarming the wireless units after installation will allow the wireless link to adaptively select its own operational modulation mode. • Restricted because of byte errors on the wireless link: During normal operation the wireless link monitors its performance. If byte errors are detected during normal data transmission / reception the wireless unit automatically changes the active modulation mode to a more robust mode in order to reduce the number of errors. • Restricted because a DFS channel change is in progress: During Spectrum Management (DFS) channel changes the wireless unit temporarily reduces the modulation mode to BPSK ½. • Restricted due to the low Ehthernet link speed: If the Ethernet link speed is less that the instantaneous wireless link capacity then the modulation mode is optimized so that the Ethernet link speed is satisfied using the most robust modulation mode. • Limited by the wireless conditions: The wireless link capacity is limited by the current wireless conditions e.g. interference, excess path loss, etc… Range: The range17 between the peer PTP 400 Series Bridge units. Refresh Page Period:18 - The Status page refreshes automatically according ti the setting entered here (in seconds). 17 The 400 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 “Properties” web page section 8.3.19 18 This option is only available to the System Administrator
748.3 System Administration Pages The following menu options are available for the system administrator and can be password protected. Figure 28 shows the ‘System Administration Login’ page. By default a system admin password is not set. Simply click the login button to access the system administration features. Once the password has been set using the ‘Change Password’ menu item, the system administration pages will only be available after the user has entered the correct password. Figure 28 - System Administration Login Page The features that are only available to the system administrator are: • Configuration • Statistics • The Installation Wizard • Software Upgrade • Spectrum Management including DFS • Remote Management • Diagnostics Plotter including CSV Download • Password Management • License Key Management • Properties • System Reboot
758.3.1 System Configuration Page The configuration page (Figure 29) is used by the system administrator to configure the PTP 400 Series Bridge. Figure 29 - Configuration Page While 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 link, modulation and physical components. Link Name: User defined identity for the unit (max 63 characters). Link Location: Can be used to describe the location of the equipment or any other equipment related notes (max 63 characters). Master Slave Mode: 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.
76Link Mode Optimization: By default, Link Mode Optimization of a point-to-point link is set to ‘IP Traffic’. In this configuration the wireless minimizes packet transmission errors by automatically adapting the active modulation mode based on instantaneous vector error measurements and the presence of codeword errors. This mode of operation is recommended for connection oriented IP traffic protocols where packet loss is perceived by the protocols as an indication of network congestion. It is recommended that when using this mode of operation the ARQ state is set to ‘enabled’. The ‘TDM Traffic’ mode is recommended for E1 / T1 applications and connectionless oriented protocols. In this mode the wireless link is optimized for minimum transmission latency and preservation of data throughput by allowing the link to maintain a higher modulation mode in the presence of a limited number of codeword errors. It is recommended that when operating the link in TDM mode that the ARQ state is set to disabled and that the Spectrum Management controls are used to fix the wireless link to a single frequency. This can be achieved by using the installation wizard to configure single frequency operation. In either case, a system reboot will be required. Link Symmetry: By default Link Symmetry of a point-to-point link is ‘Symmetrical Data Rate (1:1)’ in this configuration the ratio of time the wireless link spends transmitting and receiving is equal. When Link Symmetry is configured to Asymmetric Data Rate (2:1) the wireless link Master will spend twice as long transmitting as receiving. It should be noted that the data rate available to the end users might not follow these ratios exactly. The exact data rates will be dependant on the prevailing modulation modes. Throughput Optimization: Throughput Optimization has two distinct modes: • Data Throughput configures the wireless link for maximum data throughput. • Low Latency configures the wireless link to minimize packet latency during transmission over the wireless link. When Low Latency mode is selected, the Link Symmetry is automatically reconfigured to a symmetric link. Link asymmetry is not supported in Low Latency mode. Note: The “Throughput Optimization" option is not available on 4.9GHz variants. ARQ State: Automatic Repeat reQuest (ARQ) is a mechanism where packets lost due to transmission errors over the wireless link are retransmitted rapidly. The retransmission helps to prevent TCP congestion mechanisms from inadvertently interpreting intermittent packet loss as network congestion. ARQ must be enabled on both ends of the point-to-point link for it to function.
77Target Receive Modulation Mode: This is the maximum mode the unit will use as its adaptive modulation. The modulation modes available are: • BPSK 1 / 2 • QPSK 1 / 2 • QPSK 2 / 3 • 16QAM 1 / 2 • 16QAM 3 / 4 • 64QAM 2 / 3 • 64QAM 3 / 4 • 64QAM 7 / 8 By default the Target Receive Modulation Mode is 64QAM 7/8. The value in brackets shows the maximum unidirectional data for the current modulation / ranging mode combination. 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 it will be limited to that country’s regulations. Ethernet Compression: When Ethernet compression is enabled all compressible Ethernet packets are transmitted over the wireless link using a compressed data format. This will have the net effect of increasing wireless link traffic throughput. Because the compression techniques used in the PTP 400 Series Bridge are CPU intensive, compression is only applied to modulation modes BPSK 1/2, QPSK 1/2 and QPSK 2/3. The net effect of compression is solely dependant on the individual packet compressibility (entropy). Random data will not produce good packet compression; however ASCII text and other non-random data sources will produce an acceptable level of compressibility. All 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 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. (See Figure 30) Figure 30 - Configuration Reboot Page
78Note: 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. 8.3.2 LAN Configuration Page The LAN Configuration page (Figure 31) is used by the system administrator to configure the network parameters for the PTP 400 Series Bridge. 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. By organizing hosts into logical groups, subnetting can improve network security and performance. Gateway 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.
79VLAN High Priority Traffic Threshold: If enabled, this sets the 802.1p VLAN user priority threshold at which bridged traffic will be treated as high-priority. Use VLAN for Management Interfaces: If enabled, this allows the use of VLAN for Management Interfaces. 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. The following warning message window is displayed when this option is enabled: Figure 32 - VLAN Warning Window
80After clicking on OK, the following VLAN options are added to the LAN Configuration window: Figure 33 - Additional VLAN options These parameters control 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 communication with the unit is lost due to mis-configuration or the user forgot the VID that has been set. The unit can be recovered by resetting the unit to factory defaults as described in Section 3.3.2 “The PIDU Plus – ”. Note: The internal Ethernet stack used to manage a unit does not support double VLAN tagged packets. Double VLAN tagged packets will be discarded. Note: If you loose contact with your unit due to mis-configuration you will need to reset your unit to factory default as described in Section 3.3.2 “The PIDU Plus – ”
81 Ethernet Configuration: This enables the Ethernet configuration to be forced rather than auto negotiated. The configuration should only be forced if you are having problems with auto negotiation. You must ensure that you configure both this unit and the Ethernet port to which it is connected identically. If you force a fixed Ethernet Configuration on the PTP 400 Series Bridge, then you MUST also force the same fixed configuration on the equipment to which it is connected. If you fail to force the configuration of the connected equipment, its automatic configuration mechanisms will normally cause a duplex mismatch, and you will receive greatly reduced throughput! Ethernet Auto Mdix: This enables/disables the Auto Medium Dependent Interface (MDI)/Medium Dependent Interface Crossover (MDIX) capability. Drop Ethernet Link On Wireless Link Down: When enabled, this causes the Ethernet link to be dropped briefly when the Wireless link drops. This is so that spanning tree algorithms can quickly detect that there is a problem Local Packet Filtering: When Local Packet Filtering is Enabled, the bridge learns the source MAC addresses of devices transmitting Ethernet packets on the local Ethernet network, and only bridges packets to the remote unit if the destination MAC address has not been learned as a 'local' device. When Local Packet Filtering is Disabled the bridge does not learn the source MAC addresses of devices transmitting Ethernet packets on the local Ethernet network, and bridges ALL Ethernet packets received to the remote unit. Local Packet Filtering should be enabled when no external switching/routing hardware is present.
828.3.3 Save and Restore Menu The save and restore feature of a PTP 400 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 400 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. To save the configuration file click on the ‘Save Configuration File’ button (Figure 34 and Figure 35) and save the configuration file (.cfg) to the hard drive of your computer19, 20. Figure 34 - Save and Restore Configuration Page 19 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. 20 The configuration file name 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.

84The configuration file is encoded using an ASCII encoding scheme. An example is show in Figure 36. # Motorola PTP 400 Series Configuration file # # MAC Address :- 00:04:56:00:20:a2 # IP Address :- 169.254.1.1 # License Key :- 3D3D-92D5-3FD3-1AF1 # Software Version :- 04-00 # Creation Date :- 17-Nov-06 20:03:23 # # To playback this configuration file into the unit, use the Save and Restore configuration webpage: # <config>+.BP9)7HC;O)DS.UNPAGUTLIHJ:",\K.]"3F6'0*XR14+>) !3-MZ-VF … </config> Figure 36 - Example Configuration File WARNING: 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. 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 replaced 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 Install guide supplied with replacement wireless unit or directly from Motorola. Please note that the target MAC address at the other end will need to change.
85The 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 37). The user will then be prompted to confirm the action (Figure 38). Figure 37 - Restore Configuration File Pop Up Screen
86 Figure 38 - Reset Configuration and Reboot Confirmation Pop-up On confirmation the PTP 400 Series bridge will: o Upload the configuration file o Perform data integrity checking o Erase previous configuration o Apply the new configuration o 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 36. WARNING: A reboot is always required to restore a configuration file.
878.3.4 Statistics Page The PTP 400 Series Bridge statistics page is designed to display some key statistics of the Ethernet Bridge and the underlying wireless performance. Figure 39 - System Statistics

938.3.5 Install Wizard 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 7.7.10 “Aligning the ODUs”. 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 default configuration data. Table 11 shows a sample link configuration. The values highlighted have been committed to the wireless units non-volatile storage. Example PTP 400 Series Bridge Configuration Data For your convenience these two units have been pre-configured as a link Units: ODU serial number ODU serial number 0167800002BE 0167800002BF Ethernet MAC address Ethernet MAC address 00:04:56:00:02:BE 00:04:56:00:02:BF Configured as: Master Slave Target MAC address Target MAC address 00:04:56:00:02:BF 00:04:56:00:02:BE License Key License Key A471-FE88-428D-E1F3 534F-4F54-D1B0-E2DA IP Address IP Address 169.254.1.2 169.254.1.1 Table 11 - PTP 400 Series Bridge Factory Configuration Values The factory default configuration is written to the ‘semi-permanent’ configuration bank. WARNING: The factory default configuration is limited in range to 40 Km (25 miles). If you wish to install a wireless link with a range of > 40 Km (> 25 miles) and < 200 Km (< 124 miles) you must follow the ‘Manually Configuring the Wireless Units’ in section 8.3.5.1.
948.3.5.1 Manually Configuring the Wireless Units If the installer / system administrator wishes, they may modify the default installation configuration. If only the IP addresses are incorrect it is recommended that the values are changed via the configuration menu (Section 8.3.1). If any other parameters require modification then it is recommended that the system administrator use the Installation Wizard. The operational software for the PTP 400 Series Bridge requires a license key to enable the wireless bridging capability and program region code specific parameters in to the unit. Please refer to Section 8.3.18 for more information on how to enter and validate a license key into the unit. 8.3.5.2 Internet Protocol Configuration Step 1 of the installation wizard requires the installer to enter the Internet Protocol (IP) configuration. Figure 41 - Installation Wizard Internet Protocol Configuration.
95IP 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. Gateway 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: This controls whether the management interfaces (HTTP/SNMP/SMTP/SNTP) use a VLAN. Selecting this option first presents the user with the warning box shown in Figure 42, then presents the user with extra fields in which to enter the Management VLAN ID, Priority and whether to validate the VLAN ID, as shown in Figure 43. Figure 42 - VLAN Warning
96 Figure 43 - Additional VLAN Management Options Once complete click the ‘Submit Internet Protocol Configuration’ button or the ‘Next’ link. Note: The internal Ethernet stack used to manage a unit does not support double VLAN tagged packets. Double VLAN tagged packets will be discarded. Note: If you loose contact with your unit due to mis-configuration you will need to reset your unit to factory default as described in Section 3.3.2 “The PIDU Plus – ”
978.3.5.3 Wireless Configuration A discussion of the wireless configuration and its relationship to the band of operations is contained in section 5 “ General Considerations”. It is recommended that the installer reads this section before commencing with the product installation. Step 2 of the installation wizard requires the installer to enter the wireless configuration parameters: Figure 44 - Installation Wizard Wireless Configuration Target MAC Address: 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 400 Series system is shipped as a pair of units with pre-loaded correct MAC addresses. 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.
98Master Slave Mode: At this point it is necessary to decide which end will be designated as 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: By default Link Mode Optimization of a point-to-point link is set to ‘IP Traffic’. In this configuration the wireless minimizes packet transmission errors by automatically adapting the active modulation mode based on instantaneous vector error measurements and / or the presence of codeword errors. This mode of operation is recommended for connection oriented IP traffic protocols where packet loss is perceived by the protocols as an indication of network congestion. It is recommended that when using this mode of operation that the ARQ state is set to enabled. The ‘TDM Traffic’ mode of link optimization is recommended for T1 / E1 applications and non-connection oriented protocols. In this mode the wireless link is optimized for minimum transmission latency and preservation of data throughput by allowing the link to maintain a higher modulation mode in the presence of a limited number of codeword errors. It is recommended that when operating the link in TDM mode that both ARQ state is set to disabled and the Spectrum Management controls are used to fix the wireless link to a single frequency. This can be achieved by using the installation wizard to configure single frequency operation (system reboot will be required) or by using the Spectrum Management channel barring (a system reboot will not be required). Link Symmetry: By default Link Symmetry of a point-to-point link is ‘Symmetrical Data Rate (1:1)’ in this configuration the ratio of time the wireless link spends transmitting and receiving is equal. When Link Symmetry is configured to Asymmetric Data Rate (2:1) the wireless link Master will spend twice as long transmitting as receiving. It should be noted that the data rate available to the end users might not follow these ratios exactly. The exact data rates will be dependant on the prevailing modulation. If the direction you want to install the link asymmetry is not achievable in the current configuration then the master and slave modes of both PTP 400 Series Bridges will need to be reversed. Throughput Optimization: Throughput Optimization has two distinct modes: • Data Throughput configures the wireless link for maximum data throughput. • Latency Optimized configures the wireless link to minimize packet latency during transmission over the wireless link. Note: The Throughput Optimization option is not available on 4.9GHz variants.
99ARQ State: Automatic Repeat reQuest (ARQ) is a mechanism where packets lost due to transmission errors over the wireless link are retransmitted rapidly. The retransmission helps to prevent TCP congestion mechanisms from inadvertently interpreting intermittent pack loss as network congestion. ARQ must be enabled on both ends of the point-to-point link for it to function. Max Transmit 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. Ranging Mode: During installation the wireless units perform automatic ranging. The ranging mode allows the installer to control the behavior of the systems automatic ranging algorithms. The default value is 0 to 40 km22 (0 to 25 miles). If the installer is required to install a link of greater than 40 km (25 miles) then the ranging mode attribute MUST be configured to ‘0 to 100km’ (0 to 62 miles) or ‘0 to 200km’ (0 to 134 miles) mode depending on the range of the link. Likewise selecting the 0 to 5 km (0 to 3 miles) mode for links under 5 km (3 miles) will give you optimal performance. Target Range: Installers that know the range between the two wireless units to within ± 1 km (± 0.62 mile) can use the target range mode. The main advantage of the target range mode is that it reduces the time taken by the units to range. To use the target range mode the installer MUST select Target Range as the ranging mode and enter the approximate range in km in the Target range data entry field at both ends of the link. Spectrum Management Control: Is used to configure the PTP 400 Series Bridge Spectrum Management features, see section 8.3.8 for more details. I-DFS is the abbreviation for intelligent Dynamic Frequency Selection. This feature continually monitors the spectrum looking for a 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. Lower Center Frequency: The software for the PTP 400 Series Bridge allows a user to optionally adjust the channel center frequencies. See section 5 “General Considerations” for further information. This field is only available in i-DFS mode on 5.4 GHz and 5.8 GHz variants. 22 If preferred 400 Series Bridge range functions can be configured to operate in miles, see the Properties page in section 8.3.19.
100Warning: 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 re-establishment. 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 400 Series Bridge allows a user to optionally fix transmit and 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-channel 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. Warning: Ensure that the Rx and Tx frequencies are correct. Figure 45 shows a sample fixed frequency configuration. See section 5 “ General Considerations” for further information. Figure 45 - Fixed Frequency Operation
101Default Raster: When the Default Raster option is enabled the pull down selection menus displayed for Fixed Tx Frequency and Fixed Rx Frequency allow the selection of frequencies available within the default channel raster. When this option is not enabled the pull down selection menus display all available channel centre frequencies. This option is provided to ease the selection of fixed channel frequencies. Fixed Tx Frequency: This field controls the units Transmit frequency. Fixed Rx Frequency: This field controls the units Receive frequency. Installation Tones: This option allows the operator to enable of disable the audible installation tones.
1028.3.5.4 Confirm Configuration Step 3 of the installation wizard allows the installer to review and confirm the installation information before committing the information to non-volatile memory, as shown for different configuration in Figure 46, Figure 47 and Figure 48. Figure 46 - Installation Wizard Confirm Configuration
103 Figure 47 - Installation Wizard Confirm Configuration – Fixed Frequency
104 Figure 48 - Installation Wizard Confirm Configuration – Connectorized
105If all the settings are correct and appropriate click the “Confirm Configuration and Reboot Unit” button. All the attributes are committed to non-volatile memory. Immediately following the write to non-volatile memory the unit is reset. Note: If you have changed the Ethernet parameters you must reconnect using the correct network and address settings. If the installer wishes to modify the installation configuration then the ‘Back’ link can be used to access the installation wizard steps described above. 8.3.5.5 Disarm The next step of the installation wizard is the Disarm Phase. Figure 49 - Disarm Installation.
106Once section 7.7.10 “Aligning the ODUs” is complete pressing the “Disarm Installation Agent” button completes the installation process23 and the audible installation tone will be switched off. After disarming the wireless link the user is presented with an optional configuration page see Figure 50. The screen presents hyperlinks to the main configuration and spectrum management pages. Figure 50 - Optional Post Disarm Configuration 2 Once the installer is satisfied with the wireless configuration options then the ‘Submit Wireless Configuration’ button or the ‘Next’ link should be clicked. 23 The installation process is completed when both ends of the link are ‘disarmed’.
1078.3.6 Graphical Install To aid the installation of wireless links two graphical installation aids have been included: • 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 51. 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 average size of a PDA screen. Wireless Link Status. Permissible values are: Up, Registering, Searching and AcquiringTrace of receive power over the previous three minutesReceive Power Bar, instantaneous receive power. The colour of is green when the wireless link status is up, otherwise it is redWireless Install Metric Figure 51 - Installation Screen The screen displays the receive power of 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. For the more technically aware the installation metric is simply the instantaneous receive power in dBm + 100.
108The 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. 8.3.7 Software Upgrade The PTP 400 Series Bridge 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 as and when necessary. The ‘Fixed’ image is only used if disaster recovery is required, i.e. if an upgrade process is interrupted or the units are reset to their factory defaults. These 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 400 Series Bridge Software image, identifiable by its ‘.dld’ file extension. The “Browse” button is used 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 process. The following figures detail the upgrade process:
109 Figure 52 - Software Upgrade – Step 1 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 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, as shown in Figure 53. If the image is not correct, the user has the option to go back and reload a new image, as shown in Figure 52.
110 Figure 53 - Software Upgrade Image Check The 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. A progress tracking web page will be presented to the user during the erasure and programming of non-volatile memory. WARNING: 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. On power up, if the software image is invalid, for any reason, the PTP 400 Series bridge will use a known good fixed image. If this occurs the user must attempt to reload the correct version of software. Figure 54 - Overall Progress Tracker
111Once the Overall Update Progress bar has reached 100%, proceed to the next step. Figure 55 - Software Upgrade Complete When the software image has been written to memory Figure 55 will be displayed showing the status of the software upload. Reboot the unit by clicking the “Reboot Wireless Unit” button. This will reboot the unit within 30 seconds, and during this time you will not be able to communicate with the unit. The unit is now fully functional. If this screen is not displayed after 60 seconds it could indicate a problem with the memory update process. The user should now power cycle the unit to start using the new software image. The unit’s boot software will automatically determine the health of the newly uploaded software image. If any problems were encountered the boot code will revert to a protected fixed software image After the power cycle the user should check that the required software image is loaded and running by re-entering the Upgrade page where the software bank status will be displayed.
1128.3.8 Spectrum Management Spectrum Management Selection (also referred to by the acronym DFS) is the PTP 400 Series Bridge wireless 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. 8.3.8.1 Wireless Channels The PTP 400 Series Bridge operates using a set of predefined channels. Section 5 ”General Considerations” contains detailed information on this subject with regards each product variant. It should be noted that some product variants have a channel raster smaller than their channel size. In these cases the channels overlap and the Spectrum Management displays should be read accordingly. The default channelization can be modified by varying the lower center frequency attribute in the installation wizard – see Section 8.3.5.3 “Wireless Configuration” - Lower Center Frequency. 8.3.8.2 Spectrum Management Measurements The PTP 400 Series Bridge performs four Spectrum Management measurements per TDD cycle, per channel. The measurements are subdivided into two signal peak measurements and two mean signal measurements. The peak measurements represent the peak received signal power with a resolution down to 100 ns. The mean measurement represents the mean received signal power for the 40 μs measurement period. 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 select 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 channel barring process. Measurements are still collected for all channels irrespective of the number of barred channels. 8.3.8.3 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.
113The analysis produces four key metrics for each channel: • Peak of Peaks • Peak of Means • 99.9% Percentile of the Means • Mean of Means Peak of Peaks: is the largest peak interference measurement encountered during the quantization period. This metric is useful for detecting large short duration spikes in the interference environment. 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 for 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 affect on the mean of means. Mean of Means: is the arithmetic mean24 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. 24 The arithmetic mean is the true power mean and not the mean of the values expressed in dBm.
1148.3.8.4 The Spectrum Management Master / Slave Relationship By default 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. Figure 56 shows a sample Spectrum Management web page as seen from the master. 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.
115 Figure 56 - Spectrum Management - Master Figure 57 shows a sample PTP 400 Series Spectrum Management web page as seen from the slave. It should be noted that all the key configuration attributes are not available on the slave web page.
116 Figure 57 - Spectrum Management – Slave 8.3.8.5 Spectrum Management Configuration The following section describes the user modifiable configuration accessible from the Spectrum Management web page. 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. Refresh Page Period: The page refreshes automatically according to the setting entered here (in seconds). Hopping Period: 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 and or SMTP alerts are enabled an SNMP TRAP and/or an email alert is sent, warning the system administrator of the channel change.
117Hopping Margin: Spectrum Management uses this margin when making a channel hop decision. The channel to hop to has to have an interference level 3 dBs (default) better than the current active channel. 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. Hopping Counter: Indicates the number of automatic channel changes that have occurred. Asymmetric DFS: When disabled this option 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. (Default Enabled). 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 Spectrum Management will instruct the wireless to immediately search for a better channel. If a better channel cannot be found, the PTP 400 Series Bridge will continue to use the current active channel. (Default –85 dBm) 8.3.8.6 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 conformation dialog. It should be noted that the channel bar will take effect immediately and is not related to the measurement quantization period.
1188.3.8.7 Local and Peer Channel Spectrum Graphics Spectrum Management presents its computed statistical measurements in a graphical display on both the master and slave DFS web page. Figure 58 - Sample Spectrum Management Graphic The X-axis shows a stylized view of the selectable wireless channels. See section 5 “ General Considerations” for further information. 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 to the spectral occupancy of the channel. The individual channel metrics are displayed using a colored bar, an ‘I’ bar and a peak symbol. The 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. 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. Table 12 - Spectrum Management (Non UK) change state key The top of the colored bar represents the 99.9% percentile metric for specific channel.
119The ‘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. The peak symbol (the upper small triangle above each channel ‘I’ bar) is used to indicate the peak of peaks interference measurement. 8.3.8.8 Active Channel History The active channel history is a time series display of the channels used by the PTP 400 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 59. 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 59 - Active Channel History Screen
1208.3.8.9 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 webpage. Figure 60 - Spectrum Management Time series Plot Figure 60 shows a sample time series plot. A time series plot displays the previous 145 measurement quantization periods. If the PTP 400 Series Bridge has not been running for 145 quantization periods then only the number of measurement quantization periods that are available are displayed. RED Peak of Peaks interference measurement GREEN Peak of Means interference measurement BLACK 99.9% percentile of means interference measurement BLUE Mean of Means interference measurement Table 13 - Spectrum Management time series key 8.3.8.10 Spectrum Management Online Help Because the Spectrum Management displays contain a large amount of data, symbols and color references, an online help screen has been provided see Figure 61. This screen is accessible from both the master and slave web pages.
121 Figure 61 - Spectrum Management Help Page
1228.3.9 Spectrum Management - Fixed Frequency The software for the PTP 400 Series Bridge 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 of the prevailing interference environment. (See Section 8.3.5.3 “Wireless Configuration” - Fixed Transmit Frequency, Fixed Receive Frequency). 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- Master
123 Figure 63 - Spectrum Management Fixed Frequency Screen- Slave Channel barring is disabled in fixed frequency mode; it is not required as dynamic channel hopping is prohibited in this mode. The only control available to the master is 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. The active channel history menu is removed in this mode of operation as channel hopping is prohibited. 8.3.10 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. • The only controls available to the master are the Interference Threshold attribute. This has no affect 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 14.
124When operating with RTTT Avoidance enabled or other regulatory restrictions on channel usage the following variances apply: • A 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 interference 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. Figure 64 - Spectrum Management Master Screen with Operational Restrictions
125 Figure 65 - Spectrum Management Slave Screen with Operational Restrictions The 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. Because the low signal levels encountered when a unit is powered up in a laboratory environment prior to installation (which makes the gray 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.

1268.3.11 Remote Management Page The Remote Management page (Figure 66) allows the system administrator to configure the remote management of the PTP 400 Series Bridge. Figure 66 - Remote Management
1278.3.12 SNMP (Simple Network Management Protocol) The industry standard remote management technique is SNMP (Simple Network Management Protocol). The PTP 400 Series Bridge supports version 1 and version 2c of the SNMP protocol. 8.3.12.1 Supported Management Information Bases (MIBS) The industry standard remote management technique is SNMP (Simple Network Management Protocol). The PTP 400 Series Bridge supports SNMP version 1 and version 2. The PTP 400 Series Bridge SNMP stack currently supports four distinct MIBs: 1. MIB-II, RFC-1213, The PTP 400 Series Bridge supports the ‘System Group’ and ‘Interfaces Group’. 2. Bridge MIB, RFC-1493, The PTP 400 Series Bridge supports the ‘dot1dBase Group’ and the ‘dot1dBasePortTable Group’. 3. PTP 400 Series Bridge proprietary MIB 4. WiMAX MIB SNMP TRAPs supported: • Cold Start • Link Up • Link Down • DFS Channel Change • DFS Impulsive Interference For a copy of the Motorola proprietary version 1 and version 2 MIB RFCs please consult the installation CD. 8.3.12.2 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 Trap Version: This determines which SNMP trap version the unit will send: version 1 or version 2c.
128SNMP Community String: The SNMP community string acts like a password between the networks SNMP management entity and the distributed SNMP clients (PTP 400 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: The SNMP port number used by the agent for all GET, SET, WALK PDUs. 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 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. 8.3.12.3 SMTP (Simple Mail Transport Protocol) The SMTP client is an alternative method for the PTP 400 Series Bridge to alert the outside world 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 PTP 400 Series Bridge 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 PTP 400 Series Bridge will send the alert messages.
1298.3.13 SNTP (Simple Network Time Protocol) The SNTP client allows the PTP 400 Series Bridge to obtain accurate date and time updates from a networked timeserver. The resultant time information is used by the SNMP, web page and System Reboot tasks. SNTP State: The SNTP state attribute controls the creation of the SNTP features. When enabled the following options are available: 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. SNTP Sync: Displays whether the SNTP client is in sync with the specified SNTP server. SNTP Last Sync: The timestamp of the last time the SNTP client successfully synchronized with the SNTP server. System Clock: Displays the current system clock. SNTP Time Zone: The SNTP time zone is a fixed offset from GMT that is added to the correct time to allow the expression of time in all geographic time zones. When disabled the following options are available: Set Time: Field used to set the current time (HH:MM:SS). Set Date: Pull down menus to set the current date. Time Zone: The time zone is a fixed offset from GMT that is added to the correct time to allow the expression of time in all geographic time zones. Daylight Saving: Enables daylight saving by adding one hour to the displayed system clock timestamp.
1308.3.14 Diagnostics Link performance data is stored as a set of cascaded histograms: • Histogram 1: the last hour at a resolution of 1 second • Histogram 2: the last day (24 hours) at a resolution of 1 minute • Histogram 3: the last month (30 days) at a resolution of 1 hour The histograms are linked together by cascading data from one to the next: As a histogram fills up, the data overflow is used as input to the next histogram in the chain. For example, raw data is collected at a 1 second resolution and stored in Histogram 1. Once Histogram 1 fills up, every minute the oldest minute of data (i.e. the 60 oldest seconds) are analyzed and removed from the histogram (to make room for new data). The maximum, minimum and mean values are computed and inserted as the next data set in Histogram 2. Once Histogram 2 fills up, every hour the oldest hour of data (i.e. the 60 oldest minutes) are analyzed and removed from the histogram (to make room for new data). The maximum, minimum and mean values are computed and inserted as the next data set in Histogram 3. Once Histogram 3 fills up, every hour the oldest hour of data is discarded.
1318.3.15 Diagnostics Plotter The system has the diagnostics plotter facility shown in Figure 67. Figure 67 - 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 available histograms are: • Vector Error • Rx Power • Tx Power • Signal Strength Ratio V/H • Link Loss • Rx Data Rate • Tx Data Rate • Aggregate Data Rate • Receive SNR • Rx Gain
132The diagnostic plotter displays all of the data from the cascaded Histograms 1, 2 and 3. It uses a bespoke x-axis with a compressed timeline so that resolution is not sacrificed. The most recent data is shown to the right, and the oldest data to the left. The most recent hour's worth of data from Histogram 1 is displayed between 0 minutes (0m) and 60 minutes (60m) to the right of the x-axis; Data for the previous 24 hours from Histogram 2 is displayed between 60 minutes (60m) and 25 hours (25h) in the middle of the x-axis; Data for the previous 30 days from Histogram 3 is displayed between 25 hours (25h) and 31 days (31d) to the left of the x-axis. The Trace selection allows the user to control which traces are plotted. As with other management pages the page refresh period can be used to interactively monitor the wireless link. 8.3.16 Diagnostic Download The diagnostics Download page allows the system administrator to download snapshots of system diagnostics. Figure 68 - CSV Download The following diagnostics are available: • Vector Error • Rx Power • Tx Power • Signal Strength Ratio V/H • Link Loss • Rx Data Rate • Tx Data Rate • Aggregate Data Rate • Receive SNR • Rx Gain
133All diagnostics are extracted from the associated status and statistics web page histograms. They are translated in a CSV file containing at most 578425 entries. 8.3.17 Change System Administration Password This page (Figure 69) is used to change the password for the system administration (The factory default is blank). Figure 69 - Password Change To change the password any combination of alphanumeric characters, up to 31 characters in length, can be used. 25 5784 entries comprises 3600 entries for the first hour, 1440 entries for the next 24 hours and 744 entries for the next 31 days.
1348.3.18 License Key The License Key data entry page allows the system administrator to update the PTP 400 Series Bridge license key. Figure 70 shows a sample license key data entry page. Figure 70 - Software License Key Data Entry The user must enter the license key and click the ‘Validate License Key’ button to check that the key is valid and store it in non-volatile memory. A 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 Start Guide. If subsequently the license key has been mislaid, replacement keys can be applied for online. If a valid license key is not detected in the unit’s non-volatile memory, the user is prompted to enter a valid key. It should be noted that PTP 400 Series Bridge are shipped as link pairs and as such, valid license keys are entered during the production process. Hence the user should never see the Software License Key screen (Figure 70). To enter a license key simply type or paste the license key into the data entry box and click the ‘validate license key’ button.
135If a valid license key is detected, the user will be presented with a message to say that the key is valid and that the system needs rebooting, as shown in Figure 71. Figure 71 - License Key Reboot Screen 8.3.19 Properties The web page properties screen allows the user to configure the web page interface. Figure 72 - Webpage Properties WEB Properties: Disable Front Page Login Allows access to homepage and status page web pages without forcing a login as the system administrator. WEB Properties: Disable HTTP NO-CACHE META data Removes the HTTP NO-CACHE META clause from all dynamically created web pages. Auto Logout Timer: Configures the time in minutes that the system administrator is automatically logged out if no web page activity is detected.
136Distance Units: Swaps the default metric display of distance in to imperial units. For example Km into Miles. Use Long Integer Comma Formatting: Enables long integer command formatting, i.e. 1234567 is presented as 1,234,457. 8.3.20 Reboot The reboot page allows the system administrator to perform commanded reboots of the wireless unit. The reboot page also allows the system administrator to view a list of past reboot reasons. The reasons for the reboot field has been implemented as a drop down selection box, where the latest reason for reboot is located at the top of the list. If the SNTP service from the remote management section above is active then the command reboot commands will be accompanied by the date and time the reboot was requested. Figure 73 - System Reboot
1379 Fault Finding If communication has been lost with the unit at the near end of the link, 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. 9.1 Hardware If there are problems suspected with the link hardware the following procedure is recommended. The following diagram illustrates the main system connections. Figure 74 - Main System Connections 9.1.1 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 then26 check the Ethernet LED. If neither is illuminated then there is no voltage on the power wires to the ODU. 1. Check that the mains power is connected and switched on. 2. Check that the lamp illuminates if the ODU connector is disconnected at the PTP 400 Series Bridge PIDU Plus. (Remove the PIDU Plus cover). a. If it does illuminate then either the ODU is drawing too much current, or the power wiring to the ODU is short circuited or the PSU is supplying insufficient power. The likely fault can be determined by removing the jumper (J905), 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. 26 The power indicator LED should be continually illuminated.
138b. 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 circuited by measuring the impedance across the Power connector. Is the lamp faulty? 9.1.2 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: 1. There is no power reaching the ODU because of a wiring fault 2. The ODU is faulty 3. The PIDU Plus is faulty 4. 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 cycling the mains power. Watch the Ethernet indicator for 1 minute, 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 through to running normally. If the Ethernet indicator flashes initially 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.

One second after release, flashes twice per second regularly for 10 seconds, then erases non-volatile configuration data and resets. The erasure will reset all the unit's configuration apart from the last known wireless link configuration. This ensures that after a reset the wireless link SHOULD re-establish without any user intervention. The IP address will be reset to 169.254.1.127 Recovery Switch Pressed and held for >40 seconds from power on (Recovery is pressed while power is applied) On Off while switch pressed. One second after release, flashes regularly twice per second for 10 seconds. Then erases non-volatile configuration data & the downloaded image and resets. The erasure will reset all the unit's configuration apart from the last known wireless link configuration. This ensures that after a reset the wireless link SHOULD re-establish without any user intervention. The IP address will be reset to 169.254.1.1 and the unit will boot the fixed software image. 27 It is possible that some units may have been previously configured with IP addresses 10.10.10.10 (Slave) and 10.10.10.11 (Master). Therefore the IP address will be reset to 10.10.10.10/11.
140 9.2 Radio 9.2.1 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 Range • Check Tx Power • Check License key • Check Master Slave • Check that the link has not been further obscured or the ODU misaligned. • Check the Spectrum Management 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 doesn’t work then the ODU may be faulty. 9.2.2 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 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 • Check that one or both ends of the link are not in installation mode (ARMED)
14110 System Connections The following describes the interconnections between the system components: 10.1.1 ODU to PIDU Plus Connection Figure 75 shows the interconnections between the ODU and PIDU Plus modules. Figure 75 - ODU to PIDU Plus Connection Diagram
14211 Lightning Protection EMD (Lightning) damage is not covered under warranty The recommendations in this user manual when installed correctly give the user the best protection from the harmful effects of EMD However 100% protection is not implied or 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 and by reducing the electromagnetic field. 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 un-attenuated electromagnetic field is still present. The zones are determined using the ‘rolling sphere method’, an imaginary sphere, typically 50 meters (164 feet) 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 76 and Figure 77) show this zoning pictorially:
143Equipment mounted in Zone A should be capable of carrying the full lightning current. Mounting of the ODU in Zone A is not recommended, and should only be carried out observing the rules governing installations in Zone A28 Failure to do so may put structures, equipment and life at risk. Equipment mounted in Zone B should be grounded using grounding wire of at least 8 AWG. This grounding wire should be connected to a grounding rod or the building grounding system before entry in to building. The ODU grounding point for the PTP 400 Series Bridge can be found on the bottom of the unit, and is supplied with an appropriate grounding lug for attachment to the ODU. 11.2 Detailed Installation The recommended components for an installation protected for nearby strikes are: • Grounding Kits — Andrew Type 223158 (HTUwww.andrew.comUTH) • Screened CAT 5e Cable also known as Shielded CAT 5e or CAT 5e STP (Shielded Twisted Pair) • Surge Arrestor: Transtector Type ALPU-ORT - 4 per link (www.transtector.com) • Grounding Stake • RJ45 screened connectors • 8 AWG Grounding Cable – Minimum size, preferably 6 or 4 • NB: 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) 28 Local regulations may also require the fitting of the 8 AWG ground wire referred below.

146A typical installation is shown in Figure 79 and Figure 80. Note: Grounding Points are shown unprotected for clarity. Grounding points should be adequately weatherproofed to prevent corrosion and possible loss of ground continuity. Figure 79 - Upper Grounding Configuration
147 Figure 80 - Lower Grounding Configuration The Andrew Grounding Kit at the ODU is optional providing a Surge Arrestor Unit is located at the ODU and is reliably grounded. However, it may be a regulatory requirement to cross-bond the screened CAT-5 at regular intervals up the mast. Refer to local regulatory requirements for further details.
148The PTP 400 Series Bridge PIDU Plus to ODU cable requires Surge Arrestor Units mounted at both ends of the cable. At the ODU, the Surge Arrestor Unit should be mounted within 0.3m (1 foot) of the ODU and must be grounded to the ODU. For mast installations, the Surge Arrestor Unit should be mounted at the same height as the ODU. The lower Surge Arrestor Unit should be mounted at the building entry point and must be grounded. The termination of the CAT-5 Cable into the Surge Arrestor Unit is illustrated in Table 16, Table 17 and Figure 81. The screen from the cable must be terminated into the ground terminal within the unit to ensure the continuity of the screen. Earth Sleeving should be used to cover the shield ground connection to prevent internal shorting within the unit.

The power LED should be illuminated continuously. If the 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. 2 The Ethernet LED should be observed starting with 10 slow flashes, 30 seconds after powering. This confirms that the ODU has the correct power connections, if the Ethernet LED does not light check the wiring to pins 4 & 5 and 7 & 8. 3 If a computer, switch or router is connected to the LAN side of the PIDU Plus then the Ethernet LED should flash with network activity. If the Ethernet LED does not show Ethernet activity then the network equipment and the Ethernet cables need to be checked, specifically continuity through to the ODU of pins 1 & 2 and 3 & 6.
15312 Wind Loading 12.1 General Antennas and electronic equipment mounted on towers or pole mounted on buildings will subject the mounting structure to 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 PTP 400 Series Bridge with or without the integral antenna is essentially a flat structure and so the magnitude of the lateral force can be estimated from: Force (in pounds) = 0.0042 . A . v2 Where A is the surface area in square feet and v is the wind speed in miles per hour. The lateral force produced by a single PTP 400 Series Bridge Unit at different wind speeds is shown below: Lateral Force (pounds) at wind speed (mph) Item Largest Surface Area (sq ft) 80 100 120 140 150 PTP 400 Series Bridge - integrated antenna 1.36 37 57 82 112 129 PTP 400 Series Bridge – Connectorized 1.00 27 42 60 82 95 The equivalent table in metric units is: Lateral Force (kg) at wind speed (meters/sec) Item Largest Surface Area (metres2) 30 40 50 60 70 PTP 400 Series Bridge - integrated antenna 0.1300 12 22 34 49 66 PTP 400 Series Bridge – Connectorized 0.0930 9 16 24 35 48
154Note: When the connectorized version of PTP 400 Series Bridge is used with external antennas, the figures from the antenna manufacturer for lateral force should be included to calculate to total loading on the mounting structure. 12.3 Capabilities of the PTP 400 Series Bridges The structure and mounting brackets of PTP 400 Series Bridge systems are capable of withstanding wind speeds up to 150mph (242kph). The installer should ensure that the structure to which the PTP 400 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) City, State Wind Velocity (mph) Bismarck, North Dakota 72 Buffalo, New York 91 Chicago, Illinois 87 Hatteras, North Carolina 110 Miami, Florida 132 New York, New York 99 Pensacola, Florida 114 • UK Meteorological Office (www.meto.gov.uk), peak wind speed contour maps can be found as Fig 3a/3b at: http://www.meto.gov.uk/education/historic/1987.html
15513 PTP 400 Series Bridge - Connectorized version of the PTP 400 Series bridge 13.1 Scope This section details the changes and additional features relevant to the Connectorized version of the PTP 400 Series bridge. 13.2 Product Description 13.2.1 Hardware The Connectorized version of the PTP 400 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 400 Series Integrated product. 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 83 - Connectorized version of the PTP 400 Series bridge Outdoor Unit Note: Connectorized version of the PTP 400 Series bridge are supplied without Antennas
15613.2.2 Antenna Choices – 4.9 GHz The integrated antenna has a gain of 22dBi. In FCC/Industry Canada regions when using antennas with >26 dBi of gain it is necessary to turn down the TX Power by the number of dB that 26 dBi has been exceeded. 13.2.3 Antenna Choices – 5.8 GHz The integrated antenna has a gain of 23.5 dBi. In non-FCC regions antenna choice is not restricted but any region specific EIRP limit should be obeyed, see Table 7 in section 5.2 “Region Codes” In FCC regions external antennas from the list in Section 13.7 “Antennas for 5.8GHz FCC Regions” can be used with the Connectorized version of the PTP 400 Series bridge. These are approved by the FCC for use with the product and are basically constrained by the following limits: • Single Polarization Flat Plate Antennas – up to 28dBi per antenna. • 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 400 Series bridge and the antenna ports must not be less than 1.2dB 13.3 Software/Features The variant operates in the same way as the basic PTP 400 Series Bridge product and is released initially with the feature set of the Connectorized version of the PTP 400 Series bridge. The areas where the functionality is modified are:
15713.3.1 Status Page Figure 84 - Connectorized version of the PTP 400 Series bridge Status Page The link loss calculation presented on the Status Page on 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 version of the PTP 400 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-2-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.
15813.3.2 Configuration Pages The amended Configuration Web page is shown below as Figure 85. Figure 85 - Connectorized version of the PTP 400 Series bridge ‘System Configuration’ Page Antenna Gain: Gain of the antenna you are connecting to the unit, see Table 20 - Allowed Antennas for Deployment in USA/Canada. Note: The default Antenna gain for the 4.9 GHz variant is 22 dBi. Cable 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. EIRP: (Effective Isotropic Radiated Power) This field indicates the EIRP, in dBm, for the Entered “Max Transmit Power”, “Antenna Gain” and “Cable Loss” parameters.
15913.3.3 Installation Pages The installer is prompted to enter the Antenna Gain and Cable Loss (Connectorized version of the PTP 400 Series bridge to antenna) at each end of the link. The Installation Page(s) is shown as Figure 86 to Figure 88. Figure 86 - Connectorized version of the PTP 400 Series bridge ‘Installation Wizard’ Page Additional fields on this page are “Antenna Gain”, “Cable Loss” and “EIRP”. See the previous section for more detail.

16213.4 Deployment Considerations The majority of radio links can be successfully deployed with the PTP 400 Series Bridge. It should only be necessary to use external antennas where the Link Budget Calculator 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. The 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 link estimation tools. For more information see the Motorola web site. 13.6 Regulatory Issues In countries where FCC regulations are not relevant, installations should 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 Table 7 in section 5.2 “Region Codes” for any EIRP restrictions that may apply in your region. 13.6.1 Antenna Choice (5.8GHz FCC Regions Only) The antennas which can be deployed with the Connectorized version of the PTP 400 Series bridge are shown in Table 20.
16313.6.2 Cable Losses (5.8 GHz FCC Regions Only) The FCC approval for the product is based on tests with a cable loss between the units of 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).

The actual installation procedure will depend on antenna choice, cable choice, required antenna separation etc. 13.8.1 Antenna Choice There are a wide variety of antennas that can be used with the Connectorized version of the PTP 400 Series bridges. The main selection criteria will be the required antenna gain. The secondary criteria should be the ease of mounting and alignment.
16613.8.2 Cables and Connectors Cables should be selected using the above criteria. However is 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 an adhesive lined heat shrink sleeve that is fitted over the cable/connector interface. The connectors required at the Connectorized version of the PTP 400 Series Bridge end of the antenna cables are N-Type Male. The connectors required at the antenna end of the antenna cables is dependant on the antenna type chosen. 13.8.3 Tools The tools required for mounting an Connectorized version of the PTP 400 Series Bridge are the same as those required for an Integrated PTP 400 Series Bridge unit 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. 13.8.4 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 13.8.5 Mounting 13.8.5.1 Connectorized version of the PTP 400 Series bridge A Connectorized version of the PTP 400 Series Bridge ODU is shipped with the same bracket as is supplied with an Integrated ODU. Details on the use of this bracket can be found in section 3.3.7 “Mounting Brackets”. The ODU 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.
167When using dual polar antennas the ODU 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 13.7 ”Antennas for 5.8GHz FCC Regions”). When using separate antennas the ODU should be mounted in such a position as to minimize both cable runs between the ODU and the antennas. It is not necessary to mount the ODU at the mid point between the antennas. 13.8.6 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 (66 feet) apart or at a certain distance from the ground to get the desired results. 13.8.7 Alignment Process When aligning antennas deployed with a Connectorized version of the PTP 400 Series Bridge, it may not be possible to hear the alignment tone emanating from the ODU. In this case it may be necessary for a second installer to assist in the operation. Alternately it may be possible to extend the tube on the supplied stethoscope to give a longer reach. Tip: 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. 13.8.8 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 7.7.10 ”Aligning the PTP 400 Series ODUs”. 13.8.9 Separate Antennas When using separate antennas to achieve special diversity it is recommended that one 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 ODU
168Step 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 ODU Step 6: Connect the 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 7.7.10 “Aligning the PTP 400 Series ODUs”. Step 8: Connect the other antenna to the ODU. Step 9: Disconnect the cable to the already aligned antenna. Step 10: Align the second antenna using the tones as described in section 7.7.10 “Aligning the PTP 400 Series ODUs”. Step 11: Re-connect the second antenna to the ODU (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. Step 13: Complete the installation as detailed below. 13.8.10 Completing the Installation The installation should be completed by checking all mounting nuts bolts and screws, securing all cables and weatherproofing the installation. WARNING: Final tightening of the antenna mountings may cause the antenna alignment to be altered due to distortion in the mounting bracket caused by tightening. It is recommended that the installation tone be left turned on (armed) during this process so that any movement can be noticed and counter acted by tightening the other side of the bracket. 13.8.11 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 version of the PTP 400 Series Bridge unit 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.
16913.8.12 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. Drip loopAntenna Figure 89 - 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 give additional protection. Figure 90 shows this diagrammatically for the Connectorized version of the PTP 400 Series bridge unit 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 cables. Weatherproof N ConnectorSelf-Amalgamating TapePVC TapeEnsure that contact is made between the sealing tape and the barrel of the connectorTape beyond the end of the connector and any heat shrink material employed terminating the cable Figure 90 - Weatherproofing the Antenna Connections
17013.9 Additional Lightning Protection The following guidelines should be applied in addition to those described in Section 11 ”Lightning Protection”. 13.9.1 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 91. Connectorized ODUAntenna Cable Antenna CableAntenna Cable Grounded to tower Antenna Cables Grounded to towerAntenna Cable Grounded to tower Antenna cables should be grounded within 0.3 metres (1 foot) of the ODU and Antennas using the Andrew Grounding Assembly Figure 91 - Additional Grounding When Using Connectorized Units

17314 Wireless Link Encryption The PTP 400 Series Bridge system supports link encryption using the NIST approved Advanced Encryption Standard, FIPS-197. 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 400 Series Bridge. A license key to enable link encryption can be purchased from your Motorola Point-to-Point Solutions Provider or Distributor. AES can be activated on receipt of the activation on the Motorola License Key Generator page. 14.1 Configuring Link Encryption After purchasing AES encryption for the PTP 400 Series Bridge, 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 400 Series Bridge wireless link. 14.1.1 License Keys The first step when configuring link encryption is to enter the new license keys in both PTP 400 Series Bridge wireless units. Figure 94 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 400 Series Bridge system administration pages, please contact your designated system administrator. It must be noted that configuring link encryption will necessitate a PTP 400 Series Bridge service outage. Therefore it is recommended that the configuration process is scheduled during an appropriate period of low link utilization.
174 Figure 94 - Software License Key Data Entry 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.
17514.1.2 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 95 be used to configure AES link encryption. Figure 95 - 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 ‘AES (Rijndael)’ Encryption Algorithm. 4. At both ends of the link enter a 128-bit encryption key. Note the key consists of 32 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.
1766. Reboot both ends of the link Figure 96. 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 96 - Configuration Reboot Screen 14.2 Wireless Link Encryption FAQ 14.2.1 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. 14.2.2 Link fails to bridge packets after enabling link encryption If the wireless link status on the status web page indicates that the link is UP, 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.

18617 FAQs Q: Can I source and use my own PoE adaptor with the PTP 400 Series Bridge? No. The PTP 400 Series Bridge uses a non-standard PoE configuration. Failure to use the Motorola supplied Power Indoor Unit (PIDU Plus – PTP 400 Series) could result in equipment damage and will invalidate the safety certification and may cause a safety hazard. Q: Who is Motorola? Motorola, Inc. is a specialist wireless manufacturer with a high quality engineering team that is developing advanced radio solutions that allows high capacity building-to-building bridges to be established even in deep non-Line-of-Sight conditions. Q: Why has Motorola launched the PTP 400 Series Bridge? The PTP 400 Series Bridge is the first product in this band to feature Multiple-Input Multiple-Output (MIMO). The PTP 400 Series solutions allow wireless connections of up to 200km (124 miles) in near line-of-sight conditions and up to 10km (6 miles) in deep non-line-of-sight conditions. Q: What is Multiple-Input Multiple-Output (MIMO)? The PTP 400 Series Bridge radiates multiple beams from the antenna - which significantly protects against fading and radically increases 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. Q: What do you mean by “non-Line-of-sight”? This term refers to a wireless connection between two points without optical line-of-sight. i.e. with obstructions in between the antennas but the transmitted signal is still able to reach the receiver and produce a good quality link.
187Q: What else is special about the PTP 400 Series Bridge? There are many special features built-in to the hardware of the PTP 400 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 PTP 400 Series Bridge has a built-in web server for advanced management capabilities including detailed radio signal diagnosis. Q: In which frequency band does the PTP 400 Series Bridge operate? The Motorola point-to-point PTP 400 Series Bridges operate in the 4.9 GHz USA National Public Safety Band, the unlicensed 5.4 GHz (ETSI Band B) and 5.8 GHz (ETSI Band C and FCC ISM band). Q: Why does the PTP 400 Series Bridge operate in the 5 GHz 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. Q: Is the PTP 400 Series Bridge an 802.11a device? No. Although similar, the PTP 400 Series Bridge uses different encoding and radio transmission systems than 802.11a. In areas where 802.11a systems are operating, the PTP 400 Series Bridge will detect the 802.11a radio signals and choose a clean channel away from any interference. Q: How much power does the PTP 400 Series Bridge transmit? At all times the PTP 400 Series Bridge operates within country / region specific regulations for radio power emissions. In addition, the PTP 400 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. Q: How does the PTP 400 Series Bridge avoid interference from other devices nearby? At initialization, the PTP 400 Series Bridge monitors the available frequency channels to find a channel that is clean from interference. In operation, the PTP 400 Series Bridge continuously monitors the spectrum to ensure it is operating on the cleanest channel.
188Q: How does the PTP 400 Series Bridge integrate into my data network? The PTP 400 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 PTP 400 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. Q: How does the PTP 400 Series Bridge provide security for data traffic? The PTP 400 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. If further security is required the user is now able to optionally augment the existing high security by encoding the air interface using AES. Q: How is the Advanced Encryption Standard (AES) enabled? The AES facility is enabled by the user obtaining a license key from Motorola. Entering the key will turn on the AES option from which the user will be able to turn on AES. The default setting for AES is off. Q: How do I manage the PTP 400 Series Bridge? The PTP 400 Series Bridge has a built-in web server. At installation, the unit is configured with an IP address so that the web server can then be accessed from any browser equipped terminal. For security, access can be password protected, meaning only the network administrator can access the web based management tools. SNMP V2c is also available and the unit can be configured to send traps or email notifications via SMTP. Q: Can I use Apple Macintosh OS X to control and monitor my PTP 400 Series Bridge? Yes, but there are some restrictions. Mozilla 1.6 is recommended. There are some issues with Internet Explorer 5.2(IE) and Safari, which could mislead the user.
189Q: How will my investment be protected as new features are developed? Future enhancements can be downloaded to the unit, meaning advances in technology or changes in regulations can quickly be applied to the system without any further hardware investment. Q: Why can’t I change the channel raster centre frequencies on a PTP 49400? The PTP 49400 provides full band coverage without moving the channel raster. Therefore this option is not provided. Q: Why does the PTP 49400 not have a Latency vs. Throughput option? Due to the narrow channel Low Latency Mode and Throughput mode have the same latency and throughput. Therefore this option is not provided. Q: Why is the PTP 49400 Maximum TX power 23 dBm rather than 25 dBm? The maximum TX power is restricted to 23 dBm due to Type Approval power restrictions.
