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.
PAGE 77
8.3.1 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).
PAGE 78
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.
PAGE 79
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.
PAGE 80
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 network parameters for the PTP 400 Series Bridge. Figure 31 - LAN Configuration Page IP Address: Internet protocol (IP) address.
PAGE 81
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.
PAGE 82
After 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.
PAGE 83
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.
PAGE 84
8.3.3 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.
PAGE 85

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”. 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.
PAGE 96
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 modification then it is recommended that the system administrator use the Installation Wizard.
PAGE 97
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.
PAGE 98
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.
PAGE 99
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 this section before commencing with the product installation.
PAGE 100
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 Optimization: By default Link Mode Optimization of a point-to-point link is set to ‘IP Traffic’.
PAGE 101
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.
PAGE 102
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 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.
PAGE 103
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.
PAGE 104
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 46, Figure 47 and Figure 48.
PAGE 105
Figure 47 - Installation Wizard Confirm Configuration – Fixed Frequency 103
PAGE 106
Figure 48 - Installation Wizard Confirm Configuration – Connectorized 104
PAGE 107
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.
PAGE 108
Once section 7.7.10 “Aligning the ODUs” is complete pressing the “Disarm Installation Agent” button completes the installation process 23 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.
PAGE 109
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 51. Both the PDA and the large format installation screen have the same content and only differ in size.
PAGE 110
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. 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.
PAGE 111
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.
PAGE 112
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.
PAGE 113
Once 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.
PAGE 114
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.
PAGE 115
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.
PAGE 116
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 56 shows a sample Spectrum Management web page as seen from the master.
PAGE 117
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.
PAGE 118
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.
PAGE 119
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.
PAGE 120
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 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.
PAGE 121
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.
PAGE 122
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 60 - Spectrum Management Time series Plot Figure 60 shows a sample time series plot.
PAGE 123
Figure 61 - Spectrum Management Help Page 121
PAGE 124
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.
PAGE 125
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.
PAGE 126
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 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.

8.3.11 Remote Management Page The Remote Management page (Figure 66) allows the system administrator to configure the remote management of the PTP 400 Series Bridge.
PAGE 129
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.
PAGE 130
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.
PAGE 131
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.
PAGE 132
8.3.14 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.
PAGE 133
8.3.15 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.
PAGE 134
The 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.
PAGE 135
All diagnostics are extracted from the associated status and statistics web page histograms. They are translated in a CSV file containing at most 5784 25 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.
PAGE 136
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 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.
PAGE 137
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 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.

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.
PAGE 145
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 28 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.

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.
PAGE 156
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).

13.8.2 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.
PAGE 169
When 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.
PAGE 170
Step 3: Route and make off the ends of the Antenna cables Step 4: Connect the antenna cables at the antennas Step 5: Connect one of the antenna cables at the 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.

13.8.12 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. Antenna Drip loop 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.
PAGE 172
13.9 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. Antenna cables should be grounded within 0.
PAGE 173
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 92.
PAGE 174
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 93.

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 FIPSapproved 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.
