WinLink User and Installation Guide Version 1.795 iv FCC – User Information This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. 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 radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: -- Reorient or relocate the receiving antenna. -- Increase the separation between the equipment and receiver. -- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. Consult the dealer or an experienced radio/TV technician for help. Changes or modifications to this equipment not expressly approved by the party responsible for compliance (WinLink™ 1000) could void the user’s authority to operate the equipment. WARNING: It is the responsibility of the installer to ensure that when using the outdoor antenna kits in the United States (or where FCC rules apply), only those antennas certified with the product are used. The use of any antenna other than those certified with the product is expressly forbidden in accordance to FCC rules CFR47 part 15.204. The installer should configure the output power level of antennas, according to country regulations and per antenna type. Note: Outdoor units and antennas should be installed ONLY by experienced installation professionals who are familiar with local building and safety codes and, wherever applicable, are licensed by the appropriate government regulatory authorities. Failure to do so may void the WinLink™ 1000 warranty and may expose the end user or the service provider to legal and financial liabilities. RADWIN and its resellers or distributors are not liable for injury, damage or violation of regulations associated with the installation of outdoor units or antennas.

Chapter 2 Overview WinLink™ 1000 System Components WinLink™ 1000 point-to-point solution is made up of a number of key components. Typically, each side of the link comprises an Indoor Unit (IDU), an Outdoor Unit (ODU) and an antenna. A CAT5e cable from the IDU to the ODU provides both Ethernet and Power. The link is managed via the WinLink™ 1000 Manager application. Figure 2-1: Example of Link Architecture
WinLink User and Installation Guide Version 1.795 2-8 The Indoor Unit (IDU) The IDU provides TDM and Ethernet ports to connect to the link. It also provides power to the ODU. The IDU is available in four configurations: IDU-E A compact, half 19 inch wide, 1U plastic unit, providing up to two Ethernet ports and up to two E1/T1 interfaces. Figure 2-2: IDU-E Front Panel Figure 2-3: IDU-E Back Panel IDU-C A 19 inch, 1U metal unit, providing two Ethernet ports, 4xE1/T1 interfaces, and dry contact connector alarm. Figure 2-4: IDU-C Front Panel IDU-R A compact, half 19 inch, 1U plastic unit for 1 x T1/E1 backup, providing in addition 2 Ethernet ports and an external alarms interface. IDU-R is an indoor unit used for automatic backup of leased lines. IDU-R monitors the status of leased lines, and in the event of a connection failure automatically switches to the radio link. The user configures which of the two links is the main link and which is the backup link. IDU-R operates with all WinLink™ 1000 outdoor units.

Only a qualified person using the proper safety equipment should climb the antenna mast. Only trained professional installers should be used when installing or dismantling ODUs and masts. To mount the ODU: 1. Verify that the ODU mounting brackets are properly grounded. 2. Mount the ODU onto the mast or wall. Ensure that the unit is oriented so that the cable connectors are at the bottom. (If they are on top, water may penetrate into the unit causing damage.) Refer to Mast and Wall Installation for the ODU or O-PoE mounting instructions. 3. Connect the ground cable to the chassis point on the ODU. 4. Attach the ODU-IDU cable to the ODU RJ-45 connector. If making own ODU-IDU cable, refer to Wiring Specifications for the connector pin-out. 5. Screw in the cable glands to ensure hermetic sealing of the ODU. 6. Secure the cable to the mast or brackets using UV-rated cable ties. 7. Repeat the procedure at the remote site. 2. Note: Do not tightly secure the ODU to its mounting brackets until the alignment process of the antenna is complete. When installing the ODU, check that there are no direct obstructions in front of the ODU or interference from man-made obstacles. For O-PoE UL Listed parts and components must be used for installation. Use UL listed devices having an environmental rating equal to or better than the enclosure rating to close all unfilled openings. Warning Caution

Note: Panels may be fitted with different connector combinations than shown, depending on the model ordered. IDU-R Installation Installation of an IDU-R unit differs from other IDU models in one respect: At the rear of the IDU-R (see Figure 2-6 above) there are two jacks labeled “Trunks”. For each IDU-R, the E1 cable from outside should be plugged into one of the trunks, and the E1 cable to the other
WinLink User and Installation Guide Version 1.795 3-29 station should be plugged into the second trunk, as in the left hand side of Figure 2-7 above. Apart from the above difference, the link installation including the remaining part of the IDU installation and connection to the ODU proceeds as described as above. Connecting the Ground to the IDU Connect an 18AWG grounding cable to the grounding terminal of the device. The device should be permanently connected to the ground. Connecting Power to an IDU AC power is supplied to the WinLink™ 1000 IDU through a standard IEC 60320 connector. AC power should be supplied via a 1.5m (5 ft) standard power cable terminated by a IEC 60320 socket. A cable is provided with the unit. To connect AC power to an IDU: Connect the power cable socket to the power connector on the WinLink front panel. • Connect the power cable plug to the mains outlet. The unit turns on automatically upon connection to the mains. To connect DC power to an IDU A special 3-prong socket for DC power connection is supplied with the unit. Connecting Power to an O-PoE AC power is supplied to the O-PoE via a 3m (10 ft) 3 wire AC cable attached to the unit (pigtail). The AC cable is provided with no termination. To connect AC power to an O-PoE: Connect the power cable to a protected/shielded AC mains outlet. The AC mains outlet should be provided with circuit breaker rated 5A according to the local national electrical code. The unit will be turned on automatically upon connection to the mains. To maintain Overvoltage (Installation) Category II, install a suitable surge suppressor device in the branch circuit to limit expected transients to Overvoltage Category II values. The limits are based on IEC60664 and are also located in Table 2H of UL60950 (for mains ≤ 150V, the transient rating is 1500V; Warning
WinLink User and Installation Guide Version 1.795 3-30 for 150V < mains ≤ 300V, the transient rating is 2500V; for 300V < mains ≤ 600V, the transient rating is 4000V). Aligning Antennas with the Beeper Perform the antenna alignment using the ODU’s audible tone. The tone is not suitable for aligning the All Indoor Units (AIND). To align an AIND system, see AIND Alignment. To speed up the installation time, alignment of a WinLink™ 1000 system should be performed by two teams simultaneously, at site A and at site B. Æ To align the ODUs using the alignment tone: 1. Verify that power is connected to the IDUs at both sites. Do not stand in front of a live ODU. Provided that Site A detects the signal from Site B, the ODU starts beeping 20 seconds after power up, and continues beeping until the ODUs are aligned, and the installation is complete. 2. Verify normal operation of the IDU by the LED indications on the front panel. See IDU Front Panel Indicators. 3. Direct the antenna of site B in the direction of the site A. This is simplified if a previous site survey has been completed and azimuths are known. 4. Make an azimuth sweep of 180 degrees with the site A ODU so that the strongest signal from site B can be detected. 5. Slowly turning the site A ODU back towards the position of Site B, listen to the tone until the best signal is reached. See the following figure for audible signal variations. Warning
WinLink User and Installation Guide Version 1.795 3-31 Figure 3-8: Beeper Sequence for ODU Alignment Note: Three beeps and a pause is the best signal Two beeps and a pause, signal quality increased One beep and pause is no signal change Any other signal detects no signal between ODUs. 6. Secure the site A ODU to the mast/wall. 7. At site B, adjust the ODU slowly whilst listening to the beeper sequence until the best signal is attained. 8. Secure the site B ODU to the mast/wall. 9. Monitor the link quality for about 15 minutes to verify stability. Installing the Link During the installation procedure, the definition of all parameters is automatically applied to both sides of the link. Note: For HSS screens see Hub Site Synchronization.. Æ To install the link: 1. Verify that there is IP connectivity between the management station/laptop and the IDU, and that the WinLink™ 1000 Manager application is running. 2.

In the Service Parameters dialog box select the number of E1 connections (x1 or x2 for IDU-E, or x4 for IDU-C). Define the required transmission rate, and the distance between the sites. Æ To configure E1/T1 and Ethernet services: 1. In the Service dialog box, select one of the following: • Ethernet plus a number of E1/T1 channels (see Figure 5-6). • Ethernet data only. 2. Select the transmission rate required. • Adaptive • 9 Mbps • 12 Mbps • 18 Mps • 24 Mbps • 36 Mbps • 48 Mbps The default rate is Adaptive. ACCESS versions only operate in Adaptive mode. Adaptive Modulation - The system changes modulation automatically depending on channel characteristics in order to guarantee continuation of service. The adaptive modulation enables the user to maximize Ethernet throughput without degradation of the TDM service quality. When Ethernet only service is used, the adaptive modulation enables improving the Ethernet performance in case of air performance degradation (periodical interference or RSS changes). In event of interference at one site, there is no need to use a lower modulation at the other site (as in previous versions). In such a case the actual rate changes automatically only at the problematic
WinLink User and Installation Guide Version 1.795 5-66 site, while the second side of the link maintains the highest rate possible (Asymmetric). Adaptive modulation can be changed in both Installation and Configuration wizards. For versions 1.6 and greater, distance between the sites is automatically measured. If TDM services are selected, then the Evaluate icon shows on the screen while the maximum rate is evaluated. When evaluation is complete the icon changes and the following message is shown: Service has been evaluated, click Next to continue. 3. Click Next. The TDM Parameters dialog box or the Finish screen appears depending on which services were selected. Figure 5-6: Services Dialog Box, E1/T1 Interface
WinLink User and Installation Guide Version 1.795 5-67 Configuring TDM Operation Setting the Clock Configuration The TDM clock feature is enabled for carrier class IDU-C in addition to the hardware version 2 and greater IDU-E with TDM. A TDM dialog box will appear where IDU supports the clocking configuration feature (see Figure 5-7 and Figure 5-8). A new master clock configuration option is available in the Link Configuration Wizard. The automatic mode selects the clock from the first trunk that is working in normal mode (or is configured to loop-back maintenance). If a specific trunk is selected, this trunk shall be used as the system master regardless of the trunks state. The current master clock trunk is also displayed.

VLAN management affects all types of management connections (local, network and over the air). 7. Enter a Priority number. Figure 5-14: Configuring VLAN Settings Changing this parameter causes the management application to immediately disconnect. In order to avoid problems, it is recommended to verify the change by setting the VLAN only to one ODU, and only after verifying the VLAN network operation, change the other VLAN setting can be changed. Warning
WinLink User and Installation Guide Version 1.795 5-77 Troubleshooting: If the VLAN ID is forgotten or there is no VLAN network connected to the ODU: • Reset the device. In the first two minutes both VLAN and no VLAN connections are available. Setting the Date and Time The ODU maintains a date and time value. The date and time value should be synchronized with any Network Time Protocol (NTP) version 3 compatible server1. On power-up the ODU configures the initial date and time using an NTP server. If the server IP is not configured or is not reachable, a default time is set. When configuring the NTP server IP, you should also configure the offset from the Universal Coordinated Time (UTC). If there is no server available, you can either set the date and time, or you can set the manager workstation time. Note that manual setting is not recommended since reset, power up, or synchronization with an NTP server will override the setting. Note: The NTP uses UDP port 123. If a firewall is configured between the ODU and the NTP server this port must be opened2. It can take up to 8 minutes for the NTP to synchronize the ODU date and time. Æ To set Date and time 1. Click Configuration from the main menu. 2. Select which site to configure. The Configuration dialog box opens. 3. Select Date & Time: 1Windows XP is configured by default as a server. 2 Windows XP command w32tm /stripchart /computer:<server IP> can be use to check the NTP server connectivity

Figure 5-16: Change Date and Time - HQ dialog box Configuring the Bridge Bridge configuration is required in various network topologies, such as protection (1+1) and ring application. The bridge configuration
WinLink User and Installation Guide Version 1.795 5-79 parameters are located under the Advanced tab of the Configuration dialog box: Figure 5-17: Bridge Configuration - Site Configuration dialog box ODU Bridge Mode This parameter controls the ODU mode with two optional values, • Hub Mode – in Hub mode the ODU transparently forwards the all the packets over the wireless link. • Bridge Mode – In Bridge mode the ODU performs both learning and aging, the aging time of the ODU is fixed at 300 seconds. Note: Changing these modes requires system reset. IDU Aging time This parameter controls the IDU aging time. The IDU has a 2047 MAC address-learning table. The aging time parameter controls the time each MAC address is dropped from the table. Default value is 300 seconds.
WinLink User and Installation Guide Version 1.795 5-80 Note: Any change to these parameters is effective immediately. Each side of the link can be configured separately. • The following list details common configurations; both sides are must be configured with the same parameter. • Standard (Default) Configuration for Ethernet Applications • Set IDU aging to 300 seconds, ODU set to Bridge mode • Fast aging mode – for rapid network topology changes • Set IDU aging to one second, ODU set to Hub mode. • Hub Mode • The ODU is set to HUB mode. IDU aging is not applicable. • Ethernet Bridge The ODU is set to Bridge mode. The IDU aging is not applicable. Configuring Ethernet Mode The Ethernet mode is configurable for line speed (10/100BaseT) and duplex mode (half or full duplex). This mode provides an Auto detect feature where the line speed and duplex mode are detected automatically using auto negotiation. Use the manual configuration when external equipment does not support auto negotiation. The default setting is Auto Detect. The maximum Ethernet Information Rate can be limited via the pull down menu. The default setting is Best Effort. Note: It is not recommended to configure the port that is used for the management connection, since a wrong configuration can cause management disconnection or Ethernet services interruption. Æ To configure the Ethernet Mode: 1. From the Configuration menu, select the site to reconfigure. The Site Configuration dialog box opens. 2. Click Advanced > Ethernet. 3. In the Ethernet Ports Configuration pane, use the drop-down menu to select the LAN configuration.
WinLink User and Installation Guide Version 1.795 5-81 4. Click Apply to save the changes. Note: It is possible to close the Ethernet service by disconnecting the Ethernet port. The user should be aware that it is possible to close the port and not have any access to the device. If this should occur the workaround is as follows: • Connect the system from the remote site • Connect via other Ethernet port (IDU-C) • Power down the equipment and connect immediately after the power up (the fastest way is to enter install mode). Setting the Maximum Information Rate The maximum Ethernet throughput of the link can be limited. The default setting is Best Effort, where the highest information rate available for the link conditions and settings is used. Æ To set the Ethernet information rate: 1. From the Configuration menu, select the site to reconfigure. 2. Click Advanced > Ethernet The Configuration dialog box opens. 3. In the Information Rate pane, use the drop-down menu to select the maximum Information Rate. 4. Select Other to define the throughput with 8 Kbps resolution 5. Select Best Effort for the highest information rate possible for the link conditions and settings 6. Click Apply to save the changes. Note: ACCESS systems have a maximum rate of 2048 kbps. Configuring the Jitter Buffer By configuring the Jitter Buffer, the receiver jitter buffer for each site can be enlarged, thereby increasing system resistance to interference (the larger the jitter buffer, the longer the interference period that the system will overcome without TDM BER). You can also decrease the jitter buffer to decrease the system delay. The jitter buffer can be configured between 2.1 and 16.0 milliseconds.
WinLink User and Installation Guide Version 1.795 5-82 Æ To configure the Jitter Buffer: 1. In the Main menu click the Link Configuration button. 2. Run the Configuration wizard (see Figure 5-1). 3. On the Services screen, select the TDM Jitter Buffer tab: Figure 5-18: Jitter Buffer Configuration 4. Choose the desired values for HQ and Remote Site. After setting the new value, the user must evaluate the expected quality. During the evaluation the ETBE bar is displayed. 5. Click Next > to perform the change or < Back to cancel the change. Extra caution should be use when decreasing the value, since the service quality might be affected in the case of interference. In cases of asymmetric interference, the jitter buffer can be set to different values per site. In such cases the latency will also be asymmetric. Caution
WinLink User and Installation Guide Version 1.795 5-83 Changing Community Values The ODU communicates with the management application using SNMPv1 protocol. The protocol defines three types of communities: • Read-Only for retrieving information from the ODU • Read-Write to configure and control the ODU • Trap used by the ODU to issue traps. The community string must be entered at login. The user must know the password and the correct community string in order to gain access to the system. A user may have read-only privileges. It is not possible to manage the ODU if the read-write or the read community values are forgotten. A new community value may be obtained from technical support for the purpose of setting new community; the serial number or the MAC address of the ODU must be supplied. Note: The manager application and the ODU use the community strings public-bru1 for the local unit and public-bru4097 for the remote unit. These are the factory defaults, but can only be used one time on the first installation. A new community string must be set when entering the system for the first time. The read-write community and read-only community have a minimum of five alphanumeric characters. (Bru1 and bru4097 are not permitted). Changing the trap community is optional by clicking the check box. Editing Community Strings The community change dialog box is available from the Configuration > Security tab. Both read-write and read-only communities must be defined. On entering for the first time, use the following as the current community: • For Read/Write community, use netman. • For Read Only community, use public. • For Trap community, use public-bru1. Æ To change a community: 1. From the Configuration dialog box, select the Security tab 2. Type the current read-write community (default is netman).
WinLink User and Installation Guide Version 1.795 5-84 3. Select the communities to be changed by clicking the check box. 4. Type the new community and re-type to confirm. 5. Click OK to save. Figure 5-19: Changing the Community String Forgotten Community string If the read-write community string is unknown, an alternative community key can be used. The alternative community key is unique per ODU and can be used only in order to change the community strings. The alternative community key is supplied with the product, and it is recommended to keep it safe. If both the read-write community and the alternative community key are unavailable, then an alternative community key can be obtained from customer support using the ODU serial number or MAC address. The serial number is located on the product, and the MAC address is displayed in the manager inventory tab.
WinLink User and Installation Guide Version 1.795 5-85 When you have the alternative community key, click the Forgot Community button and enter the Alternative Community (Figure 5-20).

WinLink User and Installation Guide Version 1.795 5-93 Link Lock Security Feature The purpose of Link Lock Link Lock is a part of the WinLink security concept intended to meet a form of abuse encountered in the field. It is designed to prevent the situation where a remote ODU can be stolen and used as a “pirate” link to steal services or information. The Link Lock feature actually locks the local ODU to be synchronized ONLY to specific remote ODU. It is a site oriented feature. The lock can only be set from a live link. It is based on MAC authentication and is site oriented and activated on a per ODU basis. For example, if you lock the remote ODU to the local ODU, you must still lock the local ODU to the remote ODU to ensure complete two way locking. It can only be removed when the link is unsynchronized. In such a case, an alarm is raised by the WinLink™ 1000 Manager. Æ To enable Link Lock: 1. From the Link Configuration menu, select “1 Configuration Location A”. 2. Choose the Security tab. The following window is displayed: 3. Click the Link Lock checkbox and then OK. You are asked to confirm the lock:
WinLink User and Installation Guide Version 1.795 5-94 4. Click the Yes button and you are returned to the main window of the WinLink ™ 1000 Manager. Observe that a link icon is now displayed in the status bar on the bottom right of the WinLink™ 1000 Manager window. The link to the remote unit is now locked. If you repeat steps 1 and 2 above, the Security screen will look like this: The Link Lock checkbox is now unavailable. Note: The Link Lock status will only revert to unlocked as a result of a broken link, for example due to an ODU being switched off at either end of the link. A simple ODU reset at either end will restore the link to its previous locked or unlocked state.
Chapter 6 Monitoring and Testing the Link The WinLink™ 1000 Manager software enables you to monitor the link, as well as perform Loopback tests. It also provides a handy Link calculator utility for calculating the expected performance of the wireless link and the possible RF and antenna configurations for a specific link range. Retrieving Link Information (Get Link Information) The Get Link Information feature collects and writes all link and Manager information (from both sides) into a comprehensive file. The file can be used for diagnostics and should be sent to technical support to speed up assistance. The following table lists link and system information that can be monitored. Table 6-1: Get Link Information Data and Description Æ To get link information 1. On the Help menu, choose Link Information.

WinLink User and Installation Guide Version 1.795 6-101 Reinstalling/Realigning the Link It may be necessary to reinstall the link if the ODUs need to be realigned. Note: Activating Install Mode causes both sites to go into install mode, causing disruption in service for approximately fifteen seconds. Æ To reinstall the link: 1. From the Configuration menu, choose a site. The Configuration dialog box opens. 2. In the Configuration dialog box, click the Install Mode button. A message box asking if you want to enter install mode appears. 3. Click Yes to continue. The system enters Install mode and the alignment tone becomes audible. 4. Realign the ODUs and start the Installation wizard (see Chapter 3). The Link Budget Calculator The Link Budget Calculator is part of the WinLink™ 1000 Manager software and is found in the Help menu. This useful utility enables you to calculate the expected performance of the wireless link and the possible configurations for a specific link range including antenna size, cable loss and climate conditions. The Link Budget Calculator enables you to calculate the expected RSS of the link, and determine the stability of services and their effective throughput as a function of the link range and deployment conditions. The Link Budget Calculator is found on the Installation CD and from tech support so it can be used prior to installation to define and verify link parameters such as expected RSS, maximum range, and number of E1s/T1s that a link is capable of providing. It enables verification of installation quality and provides calculations that consider “real world” factors such as climate. The Link Budget Calculator screen appears in the following figure.
WinLink User and Installation Guide Version 1.795 6-102 Figure 6-7: WinLink™ 1000 - Link Budget Calculator Performance Monitoring Performance Monitoring constantly monitors traffic over the radio link and collects the following statistics data: • Site 1/Site 2 received traffic rate (in Mbps) • Site 1/Site 2 received frames rate (in Mbps) • Radio signal strength (in dBm) • Error (Blocks). WinLink™ 1000 monitors the Air interface, ETH ports, and TDM trunks. It does so continuously, even when the WinLink™ 1000 Manager is not connected. Two types of logs are recorded: y Monitor log that records statistics on traffic rate and radio signal strength. y Events log that records when the rates fall above or below a predefined threshold. Both the statistics (monitor) log and event log can be saved as TXT files.
WinLink User and Installation Guide Version 1.795 6-103 The Monitor Log The Monitor log records performance statistics for predefined intervals. You can save the monitor log to a text file, as well as display the information in an on-screen report. Saving the Monitor Log You can save the recorded Monitor log statistics to a text file. Æ To save the monitor log: 1. From the Tools menu, choose Preferences. The Preferences dialog box appears: Figure 6-8: Preferences dialog box 2. Click the Monitor Tab. 3. Select the file to save. 4. Click the check box to open the file for saving. 5. Click the button and in the Select File dialog box indicate in which folder and under what name the monitor log file is to be saved. 6. Set the time interval for adding data to the file. 7. Click OK to save the file.
WinLink User and Installation Guide Version 1.795 6-104 Viewing Performance Reports The Performance Monitor Report displays performance views of each of the interfaces3: Figure 6-9: Performance Monitoring Report window Several performance data occurrences are collected for each of the interfaces (ES, SES, and UAS), as well as Specific data per Interface type (e.g., TX and RX bytes for Ethernet). For the Air Interface, user defined thresholds data are collected. Refer to 3 Ethernet performance is not collected in PoE systems.
WinLink User and Installation Guide Version 1.795 6-105 Table 6-3 and Table 6-4, Performance Monitoring Report Toolbar. Data is collected and selectively displayed based on three time intervals as selected by the Interval radio buttons: • Current (t=0) • 15 minutes Intervals • Daily. UAS – This parameter counts the time the air link was not providing any service. There are several potential reasons for this situation; one of the sites has a power failure, high interference, maintenance operation, etc. Radio BBER Threshold – This parameter counts the seconds in which the radio performance is below a user specified threshold. The threshold is measured in percent. The threshold can be set from 0.1% up to 50%. For links with E1/T1 service the recommended value is 1% (system default). Excellent TDM service is expected below the 1% threshold, meaning that for 1% threshold, the expected BBER value should be 0 if there are no problems during the 15 min interval. If the BBER threshold increases a degraded service might be noticed. For links with Ethernet only service, 8% threshold is recommended and not 1% meaning that for 8% threshold, the recommended BBER value should be 0 if there are no problems during the 15 min interval. Since the system provides a loss less Ethernet service, there is throughput degradation in case of interference. The degradation is proportional to the BBER. Radio RSS Threshold - Radio RSS Threshold can also be used to indicate problems in the radio channel. You can verify the RSS according to the link budget calculator during the installation. A value of -5dB from the current RSS is recommended as a threshold.
WinLink User and Installation Guide Version 1.795 6-106 Table 6-3: Explanation of performance data Data type Reported Value Explanation UAS – Unavailable Seconds Seconds in which the interface was out of service. ES – Error Second The number of seconds in which there was at least an error block. Note that notation of an error block is different per interface. SES – Severe Error Second The number of seconds in which the service quality is low (the actual BBER ratio varies per interface). BBE – Background Block Error The number of error block in an interval. Generic PM Data Integrity A flag indicating that the data is valid. Note that the PM data is not valid if not all the values were stored4. Max RSL The maximum of the receive signal level (measured in dBm). Min RSL The minimum of the receive signal level (measured in dBm). Max TSL The maximum of the transmit signal level (measured in dBm)5. Min TSL The minimum of the transmit signal level (measured in dBm). RSL Threshold 1 This parameter counts the number of seconds in which the RSL is below the specified threshold. RSL Threshold 2 This parameter counts the number of seconds in which the RSL is below the specified threshold. Air Interface PM Data TSL Threshold 1 This parameter counts the number of seconds in which the RSL is above the specified threshold. 4 Possible reasons are: Clock changes within the interval and Power up reset 5 The transmit power is fixed. The value can be changed only by user configuration
WinLink User and Installation Guide Version 1.795 6-107 Data type Reported Value Explanation BBER Threshold The BBER Threshold value counts the number of seconds in which the Background Block Error Ratio (BBER) exceeds the specified threshold. Note, that the system is design for excellent quality of service with BBER of less then 1%. (at 1% BBER expected TDM BER is less than 1E-6.

Remote Power Fail Indication Remote power fail indication indicates to one side that the other side has had a power failure. The failed site sends a final trap indication about the power loss just before powering off. A Dying-Gasp circuit identifies the power failure at a minimum interval of 20 milliseconds before the IDU crash, during that interval a message notifying the power failure is sent to the remote end. Alarm output number 4 indicates link loss due to power failure at the remote end.
Chapter 7 Security WinLink™ 1000’s integrated advanced encryption support provides enhanced air interface security for carriers and private networks by ensuring user data protection with one of the most sophisticated commercially available combined encryption and authentication techniques, CCM/AES. This technique combines message authentication (preventing anti-spoofing and replay protection) with commercial encryption, and complies with the IEEE 802.11i (phase iii) security recommendations. CCM/AES uses a symmetric 128-bit encryption key (EK), and a nonce, and provides both message encryption and authenticating signature. The nonce mechanism enables the receiver to remember already received genuine messages and reject all replayed messages. Initial encryption and authentication is based on a user-defined master key (Link Password). While standard Wireless LAN encrypts only the Ethernet Payload, the AES encrypts both the source and destination MAC addresses. Entering and Changing Passwords There are two passwords necessary to use the WinLink system: • Management Password required for running the Management software • Link Password used for encryption purposes. This link password is entered when installing or configuring the link. Changing the Management Password Æ To change the management password 1. From the Tools menu, select Change Password. The Change Password dialog box appears. 2. Enter the current password, and the new password. 3. Click OK to confirm.
