3.3 Product Description This User Manual is specifically written for the 400 family 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.
Each 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.
3.3.1 The Outdoor Unit (ODU) The ODU ( Figure 2) is a self-contained unit. It houses both radio and networking electronics. H Also shown in Figure 2 is a Lightning protection unit, see Section 11 “ Lightning Protection”. A H H H 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.
3.3.2 The PIDU Plus – PTP 400 Series The PTP 400 Series BridgePIDU 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.

3.3.4 Remote LEDs and Recovery Switch The PTP 400 Series BridgePIDU 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.
The 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 or no crossed Ethernet patch cable can be used for connection to another piece of networking equipment or directly to end user equipment.
3.3.8 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.
4 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.
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 prioritise 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.
5 General Considerations 5.1 Spectrum Planning The PTP 400 Series Bridge has three frequency variants in its product range. Band Definition Frequency Channel Channel Coverage Width Raster 4.9 GHz USA National Public Safety Band 4940-4950 MHz 10 MHz 5 MHz 5.4 GHz ETSI 5 GHz band B 5470-5725 MHz 11 MHz 12 MHz 5.
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.
5.2 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) 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.
When 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.
5.3.2 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 H channels are indicated by a “No Entry” symbols displayed on the “Spectrum Management” web page, see section 8.3.
5.4.1 Raster Considerations The 4.9 GHz variant operates on a fixed 5 MHz channel raster that is set to odd center frequencies. See Figure 12. H 5.4.2 Fixed Frequency Operation When operating in ‘Fixed Frequency’ mode (see section 8.3.5.3 “ Wireless Configuration”) the H H operator can set the operating frequency independently in both directions to any of the center frequencies available in i-DFS mode. 5.4.3 Transmit Power Reduction at the Band Edges The 4.
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. H 5.5.2 Fixed Frequency Operation When operating in ‘Fixed Frequency’ mode (see section 8.3.5.3 “ Wireless Configuration”) the H H 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.
5.6 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 H H 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.

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 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. If the safety loop or its fixing is damaged in any way or has been exposed to a shock loading due to a fall it should be replaced with a new one before any further operations are undertaken. 7.7 Connecting Up 7.7.
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.
7.7.2 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.
Should it be necessary to disconnect the PIDU Plus to ODU cable at the ODU this can be achieved by removing the weather proofing gland and depressing the RJ45 locking tab with a small screwdriver as shown below: 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.
7.7.5 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.
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.
7.7.8 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.

This moisture can track down the inside of the cable, filling up the drip loop and eventually finding its way into the PIDU Plus.
7.7.9 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/ H H 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.
7.7.10 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 13 until highest pitch tone is achieved .
The 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.
The units will automatically disarm after 24 hours.
8 Web Page Reference The web user interface has three main sections. The home page presents to the operator a high level summary of the PTP 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.
The 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.
8.1.1 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 H sample alarm screen.
Install 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.
8.2 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 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.
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.
Diagnostics”. Receive Power: Receive power histogram is expressed in dBm and presented as: max, mean, min, and latest. The histogram is calculated over a one hour period. If the equipment has been running for less than one hour then the histogram is calculated over the current elapsed time. The data used to compute the histogram statistics can be downloaded in an ASCII comma separated value (CSV) format via the diagnostics CSV Download page, see section 8.3.
Diagnostics”. 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 histogram is calculated over a one hour period. If the equipment has been running for less than one hour then the histogram is calculated over the current elapsed time.
Diagnostics”. Link Loss: The link loss is the total attenuation of the wireless signal between the two point-to-point units. 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.

Values that can be presented in this field are: • Running at maximum receive mode: The wireless link is operating at its receive maximum capacity.
• Restricted due to the low Ethernet 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 range 16 F between the peer PTP 400 Series Bridge units.
8.3 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 H 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.
8.3.1 System Configuration Page The configuration page ( Figure 29) is used by the system administrator to configure the PTP H 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 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.
Target 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.
Note: At this point you will lose connection to the unit. If you have just changed the IP Address you now have to reconnect to the unit using the address just set. 8.3.2 LAN Configuration Page The LAN Configuration page ( Figure 31) is used by the system administrator to configure the H network parameters for the PTP 400 Series Bridge. Figure 31 - LAN Configuration Page IP Address: Internet protocol (IP) address.
VLAN 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.
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.
WARNING: It is recommended that after every configuration change a backup of the operation configuration is taken and archived by the system administrator. To save a copy of the current configuration navigate to the ‘Save & Restore’ web page located directly under the main configuration web page. Click on the ‘configuration’ hyperlink which references an ASCII text file named ‘config.
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.
8.3.4 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.
Wireless Good Tx Packets: Total number of good packets the bridge has sent for transmission by the wireless interface. The number in (+nn) displays the number of packets transmitted since the last page refresh. Wireless Good Rx Packets:Total number of good packets the bridge has received from the wireless interface.
The histogram is calculated over a one hour period. If the equipment has been running for less than one hour then the histogram is calculated over the current elapsed time. Aggregate Data Rate: The aggregate data rate, expressed in Mbps and presented as: max, mean, min, and latest histogram format. The histogram is calculated over a one hour period. If the equipment has been running for less than one hour then the histogram is calculated over the current elapsed time.
8.3.4.1 Detailed Counters Page The Detailed Counters Page provides: Figure 38 - Detailed Counters Ethernet Good Rx Packets: Total number of good Ethernet packets transmitted to the local Ethernet interface. The number in (+nn) displays the number of packets transmitted since the last page refresh. Ethernet Rx Fragments: Total number of short frames (<64 bytes, sometimes called runts) received from the local Ethernet interface.
Ethernet Good Tx Packets: Total number of good Ethernet packets transmitted to the local Ethernet interface. The number in (+nn) displays the number of packets transmitted since the last page refresh. Ethernet Dropped Tx Packets: Total number of Ethernet packets that were bridged to the local unit but could not be transmitted because the local Ethernet link was down. The number in (+nn) displays the number of packets dropped since the last page refresh.
Wireless Dropped Tx Packets: Total number of packets that the local unit could not bridge to the remote unit because either the wireless link was down or because Ethernet packets are being received faster than they can be transmitted over the wireless link. The number in (+nn) displays the number of packets dropped since the last page refresh. Wireless Rx Bytes: Total number of bytes that were received by the wireless interface. The number in (+nn) displays the number of bytes since the last page refresh.
8.3.5 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”. H 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.
8.3.5.1 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 H modification then it is recommended that the system administrator use the Installation Wizard.
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.
8.3.5.3 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 H H this section before commencing with the product installation.
Master 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 Optimisation: By default Link Mode Optimization of a point-to-point link is set to ‘IP Traffic’.
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 pack loss as network congestion. ARQ must be enabled on both ends of the point-to-point link for it to function.
Warning: The lower center frequency attribute must be configured to the same value for both the master and slave. Failure to do so will cause the wireless link to fail reestablishment. The only way to recover from this situation is to modify the Lower Center Frequency attribute so that they are identical on both the master and slave unit.
Default 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.
8.3.5.4 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 44, Figure 45 and Figure 46.
Figure 45 - Installation Wizard Confirm Configuration – Fixed Frequency 107
Figure 46 - Installation Wizard Confirm Configuration – Connectorized 108
If 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 47 - Disarm Installation.
Once section 7.7.10 “Aligning the ODUs” is complete pressing the “Disarm Installation Agent” H button completes the installation process 19 F 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 48. The screen presents hyperlinks to the main configuration and spectrum H management pages.
8.3.6 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 49. Both the PDA and the large format H installation screen have the same content and only differ in size.
It is hoped that the installation screen will aid the small population of installers that find it difficult to differentiate the changes in tonal output when peaking up long range and/or marginal links. The PDA installation tool is accessed via a hidden URL http:///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.
Figure 50 - Software Upgrade – Step 1 The software image will now be uploaded to the unit where it will be stored in SDRAM until it is committed to the unit’s non-volatile memory. 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.
Figure 51 - 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 (FLASH).
Once the Overall Update Progress bar has reached 100%, proceed to the next step. Figure 53 - Software Upgrade Complete When the software image has been written to memory Figure 53 will be displayed showing H 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.
8.3.8 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.
The 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.
8.3.8.4 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 54 shows a sample Spectrum Management web page as seen from the master.
Figure 54 - Spectrum Management - Master Figure 55 shows a sample PTP 58400 Spectrum Management web page as seen from the H slave. It should be noted that all the key configuration attributes are not available on the slave web page.
Figure 55 - 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.
Hopping 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.
8.3.8.7 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 56 - Sample Spectrum Management Graphic The X-axis shows a stylized view of the selectable wireless channels. See section 5 H “ General Considerations” for further information. The display separates the display of H channels to help the clarity of the resultant display.
The ‘I’ Bar is used to display the mean of means and peak of means metrics. The lower horizontal bar represents the mean of means and the upper horizontal bar represents the peak of means. The vertical bar is used as a visual cue to highlight the statistical spread between the peak and the mean of the statistical distribution. 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.
8.3.8.9 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 58 - Spectrum Management Time series Plot Figure 58 shows a sample time series plot.
Figure 59 - Spectrum Management Help Page 126
8.3.9 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.
Figure 61 - 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.
When 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 62 and Figure 63. These channels are never H H 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 63 - 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
8.3.11 Remote Management Page The Remote Management page ( Figure 64) allows the system administrator to configure the H remote management of the PTP 400 Series Bridge.
8.3.12 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.
SNMP 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.
8.3.13 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.
8.3.14 Diagnostics Link performace 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.
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.
8.3.16 Diagnostic Download The diagnostics Download page allows the system administrator to download snapshots of system diagnostics. Figure 66 - 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 All diagnostics are extracted from the associated status and statistics web page histograms.
8.3.17 Change System Administration Password This page ( Figure 67) is used to change the password for the system administration (The H factory default is blank). Figure 67 - Password Change To change the password any combination of alphanumeric characters, up to 31 characters in length, can be used.
8.3.18 License Key The License Key data entry page allows the system administrator to update the PTP 400 Series Bridge license key. Figure 68 shows a sample license key data entry page. H Figure 68 - Software License Key Data Entry The user must enter the license key and click the ‘Validate Licence Key’ button to check that the key is valid and store it in non-volatile memory.
To enter a license key simply type or paste the license key into the data entry box and click the ‘validate license key’ button. If 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 69. H Figure 69 - License Key Reboot Screen 8.3.19 Properties The web page properties screen allows the user to configure the web page interface.
Auto Logout Timer: Configures the time in minutes that the system administrator is automatically logged out if no web page activity is detected. Distance 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.
9 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 72 - Main System Connections 9.1.
b. 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.

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 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.
10 System Connections The following describes the interconnections between the system components: 10.1.1 ODU to PIDU Plus Connection Figure 73 shows the interconnections between the ODU and PIDU Plus modules.
11 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.
Equipment 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 A 23 F 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.

A typical installation is shown in Figure 77 and Figure 78. H H Note: Grounding Points are shown unprotected for clarity. Grounding points should be adequately weatherproofed to prevent corrosion and possible loss of ground continuity.
Figure 78 - 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 crossbond the screened CAT-5 at regular intervals up the mast. Refer to local regulatory requirements for further details.
The PTP 400 Series BridgePIDU 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 0.5m (1.6 feet) 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.

12 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.
Note: 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).
13 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.
13.2.2 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.
13.3.1 Status Page Figure 82 - 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.
13.3.2 Configuration Pages The amended Configuration Web page is shown below as Figure 83. H Figure 83 - 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 H Antennas for Deployment in USA/Canada. Note: The default Antenna gain for the 4.9 GHz variant is 22 dBi. Cable Loss Loss: in the cable between the ODU and the antenna.
13.3.3 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 84 to Figure 86. H H Figure 84 - 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.

13.4 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.
13.6.2 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). Length for 1.2dB Cable Loss at 5.8GHz Cable (ft) (m) LMR100 1.9 0.6 LMR200 4.6 1.4 LMR300 7.25 2.2 LMR400 11.1 3.

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. For example the Radio Waves Parabolic dishes are supplied with a mount that allows adjustment for alignment independent of the actual antenna mounting.
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 H H maximum protection from the elements but still allows easy access for making off the various connections and applying the recommended weatherproofing.
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.
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. 13.8.
13.9 Additional Lightning Protection The following guidelines should be applied in addition to those described in Section 11 H ” Lightning Protection”. H 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 89. H H Antenna cables should be grounded within 0.
13.9.2 ODU Mounted Indoors Where the ODU is mounted indoors, lightning arrestors should be deployed where the antenna cables enter the building as shown in Figure 90.
The lighting arrestors should be ground bonded to the building ground at the point of entry. Motorola recommends Polyphaser LSXL-ME or LSXL lighting arrestors. These should be assembled as show in Figure 91.
14 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 FIPSH 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.
