BreezeACCESS VL System Manual 2-2 Introducing BreezeACCESS VL BreezeACCESS VL is a high capacity, IP services oriented Broadband Wireless Access system. The system employs wireless packet switched data technology to support high-speed IP services including fast Internet and Virtual Private Networks. BreezeACCESS users are provided with a network connection that is always on, supporting immediate access to the Internet and other IP services at data rates of up to 54Mbps. The system is designed for cellular-like deployment, enabling the system architecture to vary in size and structure. A system can include any number of cells, each containing several Access Units for better coverage of densely populated areas. The system supports Virtual LANs based on IEEE 802.1Q, enabling secure operation and Virtual Private Network (VPN) services and enabling tele-workers or remote offices to conveniently access their enterprise network. The system supports layer-2 traffic prioritization based on IEEE 802.1p and layer-3 traffic prioritization based on IP ToS (RFC791). BreezeACCESS VL products operate in unlicensed frequency bands in Time Division Duplex (TDD) mode, using Orthogonal Frequency Division Multiplexing (OFDM) modulation with Forward Error Correction (FEC) coding and Time Division Multiple Access (TDMA) radios. Using the enhanced multi-path resistance capabilities of OFDM modem technology, BreezeACCESS VL enables operation in near and non-line-of-sight (NLOS) environments. These qualities enable service providers to reach a previously-inaccessible and broader segment of the subscriber population. BreezeACCESS VL is designed to enable construction of “mixed” cells, where it can be used together with unlicensed BreezeACCESS products using GFSK modulation, including BreezeACCESS II that operates in the 2.4 GHz band and BreezeACCESS V systems in the 5.7 GHz band. BreezeACCESS VL products are currently available in the 5 GHz frequency band, as shown in table Table 2-1. Table 2-1: BreezeACCESS VL Frequency Bands Series Frequency Band (GHz) BreezeACCESS VL 5.4 5.725-5.850 BreezeACCESS VL 5.4 5.470 – 5.725 The actual operating frequencies used by the system can be configured according to applicable radio regulations and specific deployment considerations. Introduction 2-3 A BreezeACCESS VL system is comprised of the following: ♦ Customer Premise Equipment (CPE): BreezeACCESS VL Subscriber Units. ♦ Base Station Equipment (BS): BreezeACCESS VL Access Units and supporting equipment. ♦ Networking Equipment: Standard Switches/Routers supporting connections to the backbone and/or Internet. ♦ Management Systems: SNMP-based Management, Billing and Customer Care, and other Operation Support Systems. BreezeACCESS VL System Manual 2-4 Subscriber Unit The Subscriber Unit (SU) installed at the customer premises enables the customer data connection to the Access Unit, providing bridge functionality and supporting a full LAN. The Subscriber Unit provides an efficient platform for high speed Internet and Intranet services. The system delivers fast access to IP-based services at a data burst rate of up to 54Mbps. The use of packet switching technology provides the user with a connection to the network that is always on, enabling immediate access to services. The SU-A-24-VL Subscriber Unit supports a radio data rate of up to 24 Mbps. The SU-A-54-VL supports a radio data rate of up to 54 Mbps. The SU-A-24/54-VL Subscriber Unit is comprised of an indoor unit (SU-NI-VL) and an outdoor unit (SU-RA-VL). The SU-RA-VL outdoor unit contains the processing and radio modules and an integrated high-gain flat antenna. The SU-NI-VL indoor unit provides the interface to the user’s equipment and is powered from the 110/220 VAC mains. The customer's data equipment is connected via a standard IEEE 802.3 Ethernet 10/100BaseT (RJ 45) interface. The indoor unit is connected to the outdoor unit via a Cat.5 Ethernet cable. This cable carries Ethernet traffic between the indoor and the outdoor units, and also transfers power (54 VDC) and control from the indoor unit to the outdoor unit. Introduction 2-5 Base Station Equipment The Access Units, installed at the Base Station site, provide all the functionality necessary to communicate with the Subscriber Units and to connect to the backbone of the Service Provider. There are 2 lines of Access Units with different architectures: Modular Base Station Equipment Standalone “Micro-Cell” Access Unit Modular Base Station Equipment The Base Station Equipment is based on the BS-SH-VL 3U chassis, which is suitable for installation in 19 inch racks. The chassis contains one or two Power Supply modules and has 8 slots that can accommodate various combinations of modules, including Network Interface (BS-AU) modules for Access Units operating in any of the bands supported by BreezeACCESS equipment, including BreezeACCESS VL, BreezeACCESS II and BreezeACCESS V. It can also accommodate a BS-GU GPS and Alarms module to support GPS-based synchronization of BreezeACCESS II or BreezeACCESS V Frequency Hopping radios. Two different types of power supply modules are available for the BreezeACCESS VL modules: The BS-PS-DC-VL which is powered from a -48 VDC power source, and the BS-PS-AC-VL, powered from the 110/220 VAC mains. The optional use of two power supply modules ensures fail-safe operation through power supply redundancy. When the same chassis is used also for BreezeACCESS II or BreezeACCESS V Access Unit modules, one BS-PS-VL power supply (AC or DC) should be used to provide power to the BreezeACCESS VL Access Units, and a different power supply module, suitable for GFSK equipment, is required for powering the BreezeACCESS II/V Access Units. Each BS-AU-VL module, together with its outdoor AU-RD-VL radio unit and an antenna comprise an AU-D-BS-VL Access Unit that serves a single sector. The AU-RD-VL outdoor unit contains the processing and radio modules and connects to an external antenna using a short RF cable. Currently available AU antennas include the following: BreezeACCESS VL System Manual 2-6 Table 2-2: AU Antennas Antenna Band (GHz) Horizontal Beam width Gain MFB58008 5.725-5.875 11° vertical 8 dB AU-Ant-5G-16-90 5.725-5.875 90° 16 dB AU-Ant-5G-15-120 5.725-5.875 120° 15 dB The BS-AU-VL indoor module connects to the network through a standard IEEE 802.3 Ethernet 10/100BaseT (RJ 45) interface. The indoor module is connected to the outdoor unit via a Cat.5 Ethernet cable. This cable carries Ethernet traffic between the indoor module and the outdoor unit, and also transfers power (54 VDC) and control from the indoor module to the outdoor unit. Standalone “Micro-Cell” Access Unit The standalone AU-D-NI-VL Access Unit is very similar to the AU-D-BS-VL unit. The AU-RD-VL outdoor unit and the antenna are the same as in the AU-D-BS-VL Access Unit. The difference is in the structure of the indoor part; in the AU-D-NI-VL Access Unit the AU-NI-VL indoor unit is a standalone desktop or wall-mountable unit rather than a 19” module. The AU-NI-VL indoor unit connects to the network through a standard IEEE 802.3 Ethernet 10/100BaseT (RJ 45) interfaces and is powered from the 110/220 VAC mains. The indoor unit is connected to the outdoor unit via a Cat.5 Ethernet cable. This cable carries Ethernet traffic between the indoor and the outdoor units, and also transfers power (54 VDC) and control from the indoor unit to the outdoor unit. Introduction 2-7 Networking Equipment The Base Station equipment is connected to the backbone through standard data communication and telecommunication equipment. The 10/100BaseT ports of the AU modules can be connected directly to a multi-port router or to an Ethernet switch connected to a router. The point-to-point link from the Base Station to the backbone can be either wired or wireless. Data to the Internet is routed to the backbone through standard routers. Management Systems The end-to-end IP-based architecture of the system enables full management of all components from any point in the system. BreezeACCESS VL components can be managed using standard management tools through SNMP agents that implement standard and proprietary MIBs for remote setting of operational modes and parameters. The same SNMP management tools can also be used to manage other system components including switches, routers and transmission equipment. Security features incorporated in BreezeACCESS VL units restrict access for management purposes to specific IP addresses and/or directions, which means from the Ethernet and/or wireless link. In addition, the Ethernet WAN can be used to connect to other Operation Support Systems including servers, Customer Care systems and AAA (Authentication, Authorization and Admission) tools. BreezeCONFIG VL The BreezeCONFIG VL utility is an SNMP-based application designed to manage BreezeACCESS VL system components and upgrade unit software versions. The system administrator can use the BreezeCONFIG VL utility to control a large number of units from a single location. In addition, BreezeCONFIG VL enables you to load an updated configuration file to multiple units simultaneously, thus radically reducing the time spent on unit configuration maintenance.

BreezeACCESS VL System Manual 4-4 Aligning the Subscriber Unit Antenna The RSSI bar display is located on the bottom panel of the outdoor unit. The ten green RSSI LEDs are used for reading the Received Signal Strength Indication. The higher the number of green LEDs indicating On, the higher the level of the received signal. This section describes how to align the Subscriber Unit antenna using the RSSI bar display. NOTE: Antenna alignment using the RSSI bar display is possible only after the Subscriber Unit is associated with an Access Unit. The associated Access Unit must be operational and the basic Subscriber Unit parameters must be correctly configured. If not, the unit will not be able to synchronize with the Access Unit. As the RSSI measurement is performed on received frames, its results are meaningless unless the Subscriber Unit is associated with an Access Unit. ¾ To align the Subscriber Unit antenna: 1. Align the antenna, which is integrated into the front side of the SU-RA unit, by pointing it in the general direction of the Base Station. 2. Verify that the power indication of the unit is On. 3. Verify that the WLNK orange LED of the unit is On, indicating that the unit is associated with an Access Unit. If the WLNK LED is Off, check that the ESSID, Frequency and Security parameters are correctly configured. If the SU is still not associated with the AU, increase the transmit power level to its maximum value. If the unit is still not associated with the AU, improve the quality of the link by changing the direction of the antenna or by placing the antenna at a higher or alternate location. 4. Rotate the antenna until the maximum RSSI reading is achieved, where at least 1 green LED is on: If you encounter prolonged difficulty in illuminating the minimum required number of green LEDs, try to improve the reception quality by placing the antenna at a higher point or in an alternate location. 5. Ensure that the front of the antenna is always facing the Base Station. However, in certain conditions, such as when the line of site to the Base Station is hampered, better reception may be achieved using a reflected signal. In this case, the antenna is not always directed toward the Base Station. 6. Secure the unit firmly to the pole. Commissioning 4-5 NOTE: In some cases, the antenna may need to be tilted to ensure that it is directed toward the Base Station antenna. For example, if the Subscriber Unit is located very close to the Base Station. 4-6 BreezeACCESS VL System Manual Configuring the Subscriber Unit’s Transmit Power Level and Maximum Data Rate The following sections describe how to configure the transmit power level and maximum data rate for Subscriber Units. The Initial Transmit Power level should be configured only when the Transmit Power Control Algorithm is disabled. Configuring the Initial Transmit Power Level If the Transmit Power Control Algorithm is enabled you can retain the default configuration of the Initial Transmit Power parameter, since the algorithm automatically sets the optimal level of the output power. If the Transmit Power Control Algorithm is disabled, it is recommended that the Initial Transmit Power parameter for each SU be set to achieve an SNR of 26 dB at the AU. Refer to Table 4-2 for the list of optimal transmit power levels at various distances, assuming a free line of sight between SU and AU. Commissioning 4-7 Table 4-2: Recommended SU Initial Transmit Power Level Vs. Distance Distance (m) SU Transmit Power (dBm) Distance (m) SU Transmit Power (dBm) 50 -22 700 75 -18.5 800 2.25 100 -16 900 3.25 150 -12.5 1000 200 -10 1250 250 -8 1500 7.5 300 -6.25 2000 10 350 -5 2500 12 400 -3.75 3000 13.75 450 -2.75 4000 16.25 500 -2 5000 18 550 -1 6000 19.75 600 -0.25 >6000 Pmax (20dBm) ¾ To verify optimal configuration of the initial transmit power level: 1. If the SU does not associate with the AU, check the configuration of the ESSID, Frequency and Security parameters. If the parameters are properly configured, verify the antenna alignment. If the unit is still not associated with the AU, set the Initial Transmit Power parameter to its maximum value. 2. After the SU is associated with the AU, check the SNR of the SU at the applicable AU. For example, you can access the AU’s Monitor program via Telnet to view the SNR values in the MAC Address Database, which can be accessed from the Site Survey menu. NOTE: The SNR measurement at the AU is accurate only when receiving transmissions from the applicable SU. If necessary, use the Ping Test utility in the Site Survey menu to verify data transmission. BreezeACCESS VL System Manual 4-8 3. If the SNR measurement of the relevant SU at the AU is lower than 26 dB, increase the value of the Initial Transmit Power parameter for the SU until an SNR measurement of 26 dB is achieved or until the Initial Transmit Power parameter is set to its maximum value. Configuring the Maximum Data Rate This section describes how to configure the maximum data rate for BreezeACCESS VL Subscriber Units. ¾ To configure the maximum data rate: 1. If, after the SU is configured to its optimal Transmit Power level, the SNR at the AU is too low, it is recommended that you configure the Maximum Data Rate parameter to a value that is lower than the maximum. This can decrease the number of retransmissions due to attempts to transmit at rates that are too high for the actual quality of the link. 2. Check the SNR of the SU at the AU. You can use Telnet to view the SNR values in the MAC Address Database, which can be accessed from the Site Survey menu. If the SNR is lower than the values required for the maximum data rate according to Table 4-3, it is recommended that you decrease the maximum data rate. NOTE: The SNR measurement at the AU is accurate only when receiving transmissions from the applicable SU. If necessary, use the Ping Test utility in the Site Survey menu to verify data transmission. 3. Configure the Maximum Data Rate according to Table 4-3, using the typical sensitivity values. It is recommended that a 2 dB margin be added to compensate for possible measurement inaccuracy or variance in the quality of the link. 4. Reset the unit to activate the new configuration.

BreezeACCESS VL System Manual 5-18 Site Survey Menu The Site Survey menu displays the results of various tests and counters for verifying the quality of the wireless link. These tests can be used to help determine where to position the units for optimal coverage, antenna alignment and troubleshooting. The counters can serve for evaluating performance and identify potential problems. In the AU, there is also an extensive data base for all SUs served by it. The following sections describe each option of the Site Survey menu. Traffic Statistics The traffic statistics are used to monitor, interpret and analyze the performance of the wired and wireless links. The counters display statistics relating to wireless link and Ethernet frames. The Traffic Statistics menu includes the following options: ♦ Display Counters: Select this option to display the current value of the Ethernet and wireless link counters. ♦ Reset Counters: Select this option to reset the counters. Ethernet Counters The unit receives Ethernet frames from its Ethernet port and forwards the frames to its internal bridge, which determines whether each frame should be transmitted to the wireless media. Frames discarded by the unit's hardware filter are not counted by the Ethernet counters. The unit transmits valid data frames received from the wireless media to the Ethernet port, as well internally generated frames, such as responses to management queries and pings received via the Ethernet port. The Ethernet Counters include the following statistics: ♦ Total received frames via Ethernet: The total number of frames received from the Ethernet port. This counter includes both invalid frames (with errors) and valid frames (without errors). ♦ Transmitted wireless to Ethernet: The number of frames transmitted by the unit to the Ethernet port. These are generally frames received from the wireless side, but also include frames generated by the unit itself. Operation and Administration 5-19 Wireless Link Counters The unit submits data frames received from the Ethernet port to the internal bridge, as well as self-generated control and wireless management frames. After a unicast data data frame is transmitted, the unit waits for an acknowledgement (ACK) message from the receiving unit. Some control and wireless management frames, as well as broadcast and multicast frames sent to more than one unit, are not acknowledged. If an ACK is not received after a predefined time, which is determined by the Acknowledge Time Limit parameter, the unit retransmits the frame until an ACK is received. If an ACK is not received before the number of retransmissions has reached a maximum predefined number, which is determined by the Number of Retransmissions parameter, the frames are dropped. The Wireless Link Counters include the following statistics: ♦ Total transmitted frames to wireless: The number of frames transmitted to the wireless media. The total includes one count for each successfully transmitted unicast frame (excluding retransmissions), and the number of transmitted multicast and broadcast frames, including control and wireless management frames. There are also separate counters for the following: Beacons (AU only) Other Management frames (excluding Beacons in AU) Data frames, including multicast/broadcast data frames and successfully transmitted unicast data frames (excluding retransmissions). Total Transmitted Unicasts, including all unicast frames successfully transmitted to the wireless media, excluding retransmissions. This count is useful for calculating the rates of retransmissions or dropped frames, since only unicast frames are retransmitted if not acknowledged. ♦ Total submitted frames (bridge): The total number of data frames submitted to the internal bridge for transmission to the wireless media. The count does not include control and wireless management frames, or retransmissions. There are also separate counts for each priority queue to which the frames were routed, which are Low, Mid and High (currently the High queue is not used for data frames). ♦ Frames dropped (too many retries): The number of dropped frames, which are the frames unsuccessfully retransmitted until the maximum permitted number of retransmissions without being acknowledged. This count includes dropped data frames as well as dropped control and wireless management frames. ♦ Total retransmitted frames: The total number of retransmissions, including all unsuccessful transmissions and retransmissions. BreezeACCESS VL System Manual 5-20 ♦ Total Tx errors: The total number of transmit errors. The following additional counters are displayed to indicate the reason for the failure: Excessive Retries (Exces RTx): The number of dropped frames, which are the frames unsuccessfully retransmitted until the maximum permitted number of retransmissions without being acknowledged. Filtered: . Underrun: The number of frames that were aborted because the rate of submitting frames for transmission exceeds the available transmission capability. Other: The number of frames that were not transmitted due to a problem other than those represented by the other counters. ♦ Total received frames from wireless: The total number of frames received from the wireless media. The count includes data frames as well as control and wireless management frames. The count does not include bad frames and duplicate frames. For a description of these frames, refer to Bad frames received and Duplicate frames discarded below. ♦ Total received data frames: The total number of data data frames received from the wireless media, including duplicate frames. Refer to Duplicate frames discarded below. ♦ Total Rx errors: The total number of frames that were not received properly. The following additional counters are displayed to indicate the reason for the failure: Phy: The number of frames that were not received properly due to a hardware problem. CRC: The number of frames received from the wireless media containing CRC errors. Overrun: The number of frames that were discarded because the receive rate exceeded the processing capability or the capacity of the Ethernet port. Other: The number of frames that were not received properly due to a problem other than those represented by the other counters. ♦ Bad frames received: The number of frames received from the wireless media containing CRC errors. ♦ Duplicate frames discarded: The number of data frames discarded because multiple copies were received. If an acknowledgement message is not received by the originating unit, the same data frame can be received more than once. Although duplicate frames are included in all counters that include data frames, only the first copy is forwarded to the Ethernet port. Operation and Administration 5-21 Ping Test The Ping Test submenu is used to control pinging from the unit and includes the following options: ♦ Destination IP Address: Displays the destination IP address of the device being pinged. Enter an IP address of 4 x 3 digit octets, separated by dots. The default IP address is 192. 0.0. 1. ♦ No. of Pings: Enter the number of ping attempts per session.

BreezeACCESS VL System Manual 5-28 Air Interface Parameters The Air Interface Parameters menu enables viewing the current Air Interface parameters defined for the unit and configuring new values for each of the relevant parameters. ESSID Parameters The ESSID (Extended Service Set ID) is a string used to identify a wireless network and to prevent the unintentional merging of two wireless network or two sectors in the same network. Typically, a different ESSID is defined for each AU. To facilitate easy addition of SUs to an existing network without a prior knowledge of which specific AU will serve it, and to support the Best AU feature, a secondary “global” ESSID, namely “Operator ESSID”, can be configured in the AU. If the Operator ESSID Option is enabled at the AU, both the ESSID and Operator ESSID will be included by the Beacon frames transmitted by it. The SU shall regard such frames if either the ESSID or the Operator ESSID matches it own ESSID. The ESSID of the AU with which the SU is eventually associated is defined as the Run-Time ESSID of the SU. Typically, the initial ESSID of the SU is configured to the value of the Operator ESSID. Once the SU has become associated with a specific AU, its ESSID can be reconfigured to the value of the ESSID of the AU. ESSID The ESSID parameter defines the ESSID of the unit. Valid values: A string of up to 31 printable ASCII characters. The default value is ESSID1. NOTE: The ESSID string is case-sensitive. Operator ESSID Parameters (AU only) The Operator ESSID Parameters submenu includes the following parameters: Operator ESSID Option The Operator ESSID Option enables or disables the use of Operator ESSID for establishing association with SUs. The default is Enable. Operation and Administration 5-29 Operator ESSID The Operator ESSID parameter defines the Operator ESSID. Valid values: A string of up to 31 printable ASCII characters. The default value is ESSID1. NOTE: The Operator ESSID string is case-sensitive. Frequency Definition Parameters Frequency Definition Submenu in AU The Frequency Definition submenu in AU includes a single parameter for setting the transmit/receive frequency: Frequency The Frequency parameter defines the transmit/receive frequency. The minimum distance between frequencies used by two neighboring AUs is the Channel bandwidth, which is 20 MHz. The range and default value depend on the radio band, as shown in Table 5-3. The frequency setting resolution is 5 MHz. Table 5-3: Frequency Ranges and Defaults Band Range Default 5.7 GHz 5740 – 5835 MHz 5780 MHz 5.4 MHz 5485 – 5710 MHz 5600 MHz Frequency Definition Submenu in SU To simplify the installation process the SU scans a definable frequencies subset after power-up. If the Best AU feature is enabled, the SU will scan the defined subset and the operating frequency will be determined by the Best AU mechanism (including the optional use of the Preferred AU feature). Otherwise the SU will try to associate with the first AU it finds. The Frequency Definition submenu in SU includes the following parameters: BreezeACCESS VL System Manual 5-30 Sub Band Lower Frequency The Sub Band Lower Frequency parameter defines the lowest frequency to be used during the scanning process. The range depends on the radio band of the unit, as shown in Table 5-4. The resolution is 5 MHz. Table 5-4: Ranges and Defaults for Sub Band Lower Frequency Band Range Default 5.7 GHz 5740 – 5835 MHz 5740 MHz 5.4 MHz 5485 – 5710 MHz 5485 MHz Sub Band Upper Frequency The Sub Band Upper Frequency parameter defines the highest frequency to be used during the scanning process. The range depends on the radio band of the unit, as shown in Table 5-5. The resolution is 5 MHz. Table 5-5: Ranges and Defaults for Sub Band Upper Frequency Band Range Default 5.7 GHz 5740 – 5835 MHz 5835 MHz 5.4 MHz 5485 – 5710 MHz 5710 MHz Scanning Step The Scanning Step parameter defines the resolution used for selecting frequencies in the sub band defined by the Sub Band Lower Frequency and the Sub Band Upper Frequency. Valid values: 5, 10, 20 MHz. Default value: 5 MHz. Frequency Subset Definition Operation and Administration 5-31 The previous parameters define a sub band of frequencies between the Sub Band Lower Frequency and the Sub Band Upper Frequency using the Scanning Step resolution. The Frequency Subset Definition option enables defining a specific subset of frequencies within this sub band to be used during scanning. When selected, a list of all valid frequencies in the band is displayed, and an index is given to each frequency. The current defined subset is also displayed. The defined subset can be modified by entering a list of desired indexes, separated by commas (no spaces). Enter A to select all frequency in the subset. The default is A, which is the list that includes all indexes of frequencies defined by the previous parameters. Best AU Parameters (SU) An SU that can communicate with more than one AU using the same ESSID may become associated with the first AU it “finds”, not necessarily the best choice in terms of quality of communication or other factors such as number of SUs serviced by each AU. The same limitation also exists if only one AU in the neighborhood has an ESSID identical to the one used by the SU, since it is not always necessarily the best choice. The topology of a fixed access network is constantly changing. Changes in base station deployment and subscriber density can accumulate to create substantial changes in SU performance. The quest for load sharing together with the desire to create best throughput conditions for the SU created the need for the Best AU feature, to enable a SU to connect to the best AU in its neighborhood. When the Best AU feature is used, each of the AUs are given a quality mark based on the level at which it is received by the SU. The SU scans for a configured number of cycles, gathering information from all the AUs it can communicate with. At the end of the scanning period, the SU reachs a Best AU decision according to the information gathered. The AU with the highest quality mark is selected as the Best AU, and the SU will immediately try to associate with it. The quality mark given to each AU depends on the level at which it is received by the SU. The Best AU selection mechanism can be overridden by defining a specific AU as the preferred AU. NOTE: Although the SU selects the Best AU based on long-term conditions prior to the decision time, it may not always be connected to the instantaneous Best AU at any given time. Note also that the decision is done only once during the scanning interval. The decision may not remain the optimal one for ever. If there are significant changes in deployment of neighboring AUs and the SUs served by them, overall performance may be improved if the applicable SUs are reset intentionally so as to re-initiate the Best AU decision process. The Best AU Parameters menu includes the following options: BreezeACCESS VL System Manual 5-32 Best AU Support The Best AU Support option enables or disables the Best AU selection feature. The default is Disable. NOTE: If the Best AU feature is not used, the SU associates with the first AU it finds whose ESSID or Operator ESSID is identical to its own ESSID. Number Of Scanning Attempts When the Best AU option is enabled, the SU gathers information on neighboring AUs for 640 milliseconds on each of the scanned frequencies. The Number of Scanning Attempts parameter defines the number of times that the process will be repeated for all relevant frequencies. A higher number may result in a better decision at the cost of an increased scanning time during which the SU is not operational. Valid values: 1 - 255. Default value: 10. The total scanning time can be calculated based on the following formula: Scanning Time (secs) = N * F * 0.64 N = Number of scanning attempts. F = Number of frequencies in the Frequency Subset defined in the Frequency Definition submenu. 0.64 seconds is the time spent on each frequency while in scanning mode. Preferred AU MAC Address The Preferred AU MAC Address parameter defines a specific AU with which the SU should associate. Gaining control of the SUs association is a powerful tool in network management. The Preferred AU MAC Address parameter is intended for applications where there is a need to dictate the preferred AU with whom the SU should associate. To prevent the SU from associating with the first viable AU it finds, the Best AU Support mechanism should be enabled. Once the SU has identified the preferred AU based on its MAC address, it will associate with it and terminate the scanning process. If the preferred AU is not found, the SU will associate with an AU according to the decision reached using the best AU algorithm. Valid values: A MAC address string. Operation and Administration 5-33 The default value for the Preferred AU MAC Address is 00-00-00-00-00-00 (12 zeros), meaning that there is no preferred AU. Show Best AU Parameters and Data The Show Best AU Parameters and Data option displays the applicable information: The Neighboring AU Data table displays for each AU that the unit can communicate with the following details: ♦ MAC Address ♦ SNR of the received signal ♦ Mark – The computed quality mark for the AU. ♦ Full – The association load status of the AU. It is defined as full if the number of SUs associated with the AU has reached the maximum allowed according to the value of the Maximum Number of Associations parameter. An AU whose associations load status is full cannot be selected as the Best AU, even if its’ computed mark is the highest. ♦ ESSID – The ESSID of the AU. In addition to the neighboring AU data table, the following information is displayed: ♦ Best AU Support ♦ Preferred AU MAC Address ♦ Number of Scanning Attempts ♦ Associated AU MAC Address (the MAC address of the selected AU) ♦ Run Time ESSID (the ESSID of the selected AU) Power Control Parameters The Automatic Transmit Power Control (ATPC) algorithm simplifies the installation process and ensures optimal performance while minimizing interference to other units. This is achieved by automatically adjusting the power level transmitted by each SU according to the actual level at which it is received by the AU. To support proper operation of the system with optimal performance and minimum interference between neighboring sectors, the ATPC algorithm should be enabled in all units. The algorithm is controlled by the AU that calculates for each received frame the average SNR at which it receives transmissions from the specific SU. The average calculation takes into account the previous calculated average, thus reducing the effect of short temporary changes in link conditions. The weight of history (the previous value) in the formula used for calculating the average SNR is determined by a configurable parameter. In addition, the higher the time that has passed since last calculation, the BreezeACCESS VL System Manual 5-34 lower is the impact of history on the calculated average. If the average SNR is not in the configured target range, the AU transmits to the SU a powerup or a power-down message. The target is that each SU will be received at an optimal level, or as high (or low) as possible if the optimal range cannot be reached because of specific link conditions. Each time that the SU tries to associate with the AU (following either a reset or loss of synchronization), it will initiate transmissions using the Current Transmit Power, which is the last value that was previously used by the ATPC mechanism. If after a certain configurable time the SU did not succeed to synchronize with the AU, it will start transmitting using the level configured for the Initial Transmit Power parameter. (If this is the first time that the SU is powered up, or if the ATPC algorithm was not used, the Current Transmit Power equals the value of Initial Transmit Power). The Initial Transmit Power parameter is used to determine the fixed transmit power level of the SU if the ATPC algorithm is not enabled. In an AU typically the maximum supported transmit power is used to enable maximum coverage. However, there may be a need to decrease the transmitted power level in order to support relatively small cells and to minimize the interference with the operation of neighboring cells. Transmit Power (AU) The Transmit Power parameter defines the transmit power level of the AU. This parameter is not part of the ATPC algorithm. Valid range: 4 to 28 (dBm), using a 1 dBm resolution. The default is 11 (dBm). Initial Transmit Power (SU) The Initial Transmit Power parameter defines the fixed transmit power level when the ATPC algorithm is disabled. If the ATPC Option is enabled this parameter serves for setting the initial value to be used by the ATPC algorithm after the first time of powering-up the unit. It will also be used by the algorithm as an initial value in the following cases: a. If the unit does not succeed to associate with the AU after reset. b. If the unit does not succeed to re-synchronize with the AU after losing synchronization. c. If the SU is associated with the AU but there are too many successive dropped frames, indicating that it transmits at a level that may be too low. The actual run-time value that is used to control the transmit power level is determined by the ATPC process. Operation and Administration 5-35 The allowed range is from -11 to 29 (dBm), using a 1 dBm resolution. The default value is 4 (dBm). ATPC Parameters in AU ATPC Option The ATPC Option enables or disables the Automatic Transmit Power Control (ATPC) algorithm. The default is Enable. Minimum SNR Level The Minimum SNR Level defines the lowest SNR at which you want each SU to be received at the AU (the lower limit of the optimal reception level range). Available values: 15 to 40 (dB). Default value: 25 (dB). Maximum SNR Level The Maximum SNR Level defines the highest SNR at which you want each SU to be received at the AU (the higher limit of the optimal reception level range). Available values: 15 to 40 (dB). Default value: 30 (dB). SNR Memory Factor The SNR Memory Factor defines the weight of history (value of last calculated average SNR) in the formula used for calculating the average SNR. The higher the value of this parameter, the higher is the weight of history in the formula. Available values: -1 to 32. -1 is for no weight for history, meaning that average SNR equals the last measured SNR. Default value: 5 Minimum Interval Between ATPC Messages The Minimum Interval Between ATPC Messages parameter sets the minimal time between consecutive power-up/power-down messages to a specific SU. Setting a low value for this parameter may lead to a higher BreezeACCESS VL System Manual 5-36 overhead and an excessive rate of power level changes at the SUs. High values for this parameter increase the time it will take until the SUs reach optimal transmit power level. Available values: 0 to 3600 seconds. Default value: 120 seconds. ATPC Power Level Step The ATPC Power Level Step parameter defines the step size to be used by the SUs for incrementing/decrementing the Current Transmit Power after receiving a power-up/power-down message. If the distance between the value of the Current Transmit Power and the desired range is smaller than the step size, the power-up/power-down message will include the specific step value required for this condition. Valid range: 1-10 (dB) Default value: 1 (dB) ATPC Parameters in SU ATPC Option The ATPC Option enables or disable the Automatic Transmit Power Control (ATPC) algorithm. The parameter takes effect immediately. However, when changed from Enable to Disable, the transmit power level shall remain at the last Current Transmit Power determined by the ATPC algorithm before it was disabled. It will change to the value configured for the Initial Transmit Power parameter only after the next reset. The default is Enable. Acknowledge Time Out The Acknowledge Time Out parameter enables augmenting the range of the system by increasing the time that the unit can wait for a response. This includes several scenarios where the unit expects a response, such as a handshake during the association process, an acknowledgement after transmitting a data frame and CTS after RTS. Increasing the range may decrease the overall performance and achievable network throughput. It should be increased only to support ranges of over 10Km. To support a link distance higher than 10Km, the delay should be increased at both the applicable SU and the AU. The Acknowledge Time Out is defined in Clock Cycles, where each Clock Cycle equals 25 nano-seconds. The valid range is from 256 (6.4 milliseconds) to 8191(205 milliseconds) Operation and Administration 5-37 The default is Maximum Number of Associations (AU only) The Maximum Number of Associations parameter defines the maximum number of Subscriber Units that can be associated with the selected AU, while still guaranteeing the required quality of service to customers. Available values range from 0-512. Default value: 512. NOTE: There is no aging time for SUs. An SU is only removed from the list of associated SUs under the following conditions: a. A SNAP frame is received from another AU indicating that the SU is now associated with the other AU. b. The SU failed to respond to a certain number of consecutive frames transmitted by the AU and is considered to have "aged out". Therefore, the database of associated SUs may include units no longer associated with the AU. If the number of associated SUs has reached the value of the Maximum Number of Associations parameter, the selected AU cannot serve additional SUs. To view the current number of associated SUs, use the Display Association Info option in the MAC Address Database menu (see page 5-22). To delete inactive SUs from the database you must reset the AU. BreezeACCESS VL System Manual 5-38 Network Management Parameters The Network Management Parameters menu enables protecting the Unit from unauthorized access by defining a set of IP addresses from which the unit can be managed via Telnet, TFTP, SNMP, or ICMP. This excludes messages generated in the unit, such as Traps or Ping Test frames, which are not filtered. You can also determine the direction from which management access is permitted, which means from the wireless media or the wired Ethernet or both. The Network Management Parameters menu includes the following options: Access to Network Management The Access to Network Management option defines the port through which the unit can be managed. The following options are available: ♦ From Wireless Link Only ♦ From Ethernet Only ♦ From Both Ethernet & Wireless Link The default selection is From Both Ethernet & Wireless Link. WARNING: Be careful not to block your access to the unit. For example, if you manage an SU via the wireless link, setting the Access to Network Management parameter to From Ethernet Only completely blocks your management access to the unit. In this case, a technician may be required to change the settings at the user’s site. Network Management Filtering The Network Management Filtering option enables or disables the IP address-based management filtering. If management filtering is enabled, the unit can only be managed by stations with IP addresses matching one of the entries in the Set Network Management IP Addresses option, described below, and that are connected to the unit via the defined port(s). The following options are available: ♦ Disable: No IP address-based filtering is configured. Operation and Administration ♦ 5-39 Enable Management IP Filtering on Ethernet Port: Applicable only if the Access to Network Management parameter is configured to either From Ethernet Only or From Both Ethernet & Wireless Link. The unit can be managed from the Ethernet port only by stations with IP addresses matching one of the entries in the Set Network Management IP Addresses parameter. If the Access to Network Management parameter is configured to From Both Ethernet & Wireless Link then no IP address-based filtering is configured for the wireless port. ♦ Enable Management IP Filtering on Wireless Link Port: Applicable only if the Access to Network Management parameter is configured to either From Wireless Link Only or From Both Ethernet & Wireless Link. The unit can be managed from the wireless port only by stations with IP addresses matching one of the entries in the Set Network Management IP Addresses parameter. If the Access to Network Management parameter is configured to From Both Ethernet & Wireless Link then no IP address-based filtering is configured for the Ethernet port. ♦ Enable Management IP filtering on Both Ethernet & Wireless Link Port: Applicable to all options of the Access to Network Management parameter. The unit can be managed from the port(s) defined by the Access to Network Management parameter only by stations with IP addresses matching one of the entries in the Set Network Management IP Addresses parameter. BreezeACCESS VL System Manual 5-40 The default selection is Disable.

Delete a Network Management IP Address The Delete Network Management IP Address option enables deleting IP address entries from the Network Management IP Addresses list. Delete All Network Management IP Addresses The Delete All Network Management IP Addresses option enables deleting all entries from the Network Management IP Addresses list. SNMP Traps The SNMP submenu enables or disables the transmission of SNMP Traps. If this option is enabled, up to 3 IP addresses of stations to which SNMP traps are sent can be defined. Send SNMP Traps The Send SNMP Traps option enables or disables the sending of SNMP traps. The following options are available: ♦ Enable Traps Sending ♦ Disable Traps Sending The default selection is Disable Traps Sending. SNMP Traps IP Destination The SNMP Traps IP Destination option enables defining up to 3 IP addresses of devices to which the SNMP Traps are to be sent. The default of all three SNMP Traps IP destinations is 0.0.0.0. SNMP Traps Community The SNMP Traps Community option enables defining the Community name for each IP address to which SNMP Trap messages are to be sent. Valid strings: Up to 8 ASCII characters. The default for all 3 addresses is public, which is the default Read community. Operation and Administration 5-41 Bridge Parameters The Bridge Parameters menu provides a series of parameter sets that enables configuring parameters such as control and filtering options for broadcast transmissions, VLAN support, and Type of Service prioritization. VLAN Support The VLAN Support menu enables defining the parameters related to the IEEE 802.1Q compliant VLAN-aware (Virtual LAN-aware) feature of the BreezeACCESS VL units. Each VLAN includes stations that can communicate with each other, but cannot communicate with stations belonging to different VLANs. The VLAN feature also provides the ability to set traffic priorities for transmission of certain frames. The information related to the VLAN is included in the VLAN Tag Header, which is inserted in each frame between the MAC header and the data. VLAN implementation in BreezeACCESS VL units supports frame routing by port information, whereby each port is connected to only one VLAN. The VLAN Support menu enables configuring the following parameters: VLAN ID-Data (SU only) The VLAN-ID Data is applicable for Access Links only. It enables defining the VLAN ID for data frames, which identifies the VLAN to which the unit belongs. Valid values range from 1 to 4094. Default value: 1. The VLAN ID-Data affects frames received from the wireless link port, as follows: ♦ Only tagged frames with a VLAN ID (VID) equal to the VLAN ID - Data defined in the unit are forwarded to the Ethernet port. ♦ The tag headers are removed from the data frames received from the wireless link before they are transmitted on the Ethernet port. The VLAN ID-Data affects frames received from the Ethernet port, as follows: ♦ A VLAN Data Tag is inserted in all untagged frames received from the Ethernet port before transmission on the wireless link. The tag includes the values of the VLAN ID - Data and the VLAN Priority - Data parameters. ♦ Tagged frames received on Ethernet port, which are meant to be forwarded to the wireless link port, are discarded. This includes frames with tagging for prioritization purpose only. BreezeACCESS VL System Manual 5-42 VLAN ID-Management The VLAN-ID Management is applicable for all link types. It enables defining the VLAN ID for management frames, which identifies remote stations for management purposes. This applies to all management applications using protocols such as SNMP, TFTP, ICMP (ping) and Telnet. All servers/stations using these protocols must tag the management frames sent to the unit with the value of the VLAN ID - Management parameter. Valid values: 1 to 4094 or 65535 (No VLAN). The default value is 65535. If the VLAN ID – Management is other than 65535: ♦ Only tagged management frames with a matching VLAN ID received on either the Ethernet or wireless link ports are forwarded to the unit. ♦ A VLAN Management Tag is inserted in all management frames generated by the unit before transmission on either the Ethernet or wireless link port. The tag includes the values of the VLAN ID - Management and the VLAN Priority - Management parameters. If the VLAN ID - Management is 65535 (No VLAN): ♦ Only untagged management frames received on either the Ethernet or wireless link ports are forwarded to the unit. ♦ Management frames generated by the unit are not tagged. The following table summarizes the functionality of the internal management port in accordance with the value of the VLAN ID - Management parameter. The table is valid for all link types. Refer to the VLAN Link Type – Access Link and Trunk Link options for some restrictions when configuring this parameter. Table 5-6: VLAN Management Port Functionality Action Management Port – Internal Receive from Ethernet Tagged frames, matching VID-M Untagged frames when VID-M=65535 Receive from Wireless Tagged frames, matching VID-M Untagged frames when VID-M=65535 Transmit Insert VID-M, PID-M Table Legend: ♦ VID-M: VLAN ID-Management ♦ PID-M: VLAN Priority-Management Operation and Administration 5-43 VLAN Link Type The VLAN Link Type parameter enables defining the functionality of the VLAN-aware capability of the unit. The available options are Hybrid Link, Trunk Link and Access Link (Access Link option is available only in SUs). The default selection is Hybrid Link. Access Link (SU only) Access Link transfers frames while tagging/untagging them since all devices connected to the unit are VLAN-unaware. Thus, the unit cannot transfer tagged frames. Table 5-7 summarizes the functionality of the data port for an Access link. Table 5-7: VLAN Data Port Functionality – Access Link Action Data Port (SU) Accept from Ethernet Untagged frames Accept from Wireless Tagged frames, matching VID-D Tag Insert VID-D, PID-D (to wireless) Tag Remove Yes (to Ethernet) Table Legend: ♦ VID-D: VLAN ID-Data ♦ PID-D: VLAN Priority-Data Trunk Link Trunk Link transfers only tagged frames, since all devices connected to the unit are VLAN-aware: Only tagged data frames received on the Ethernet or wireless link ports are forwarded. WARNING It is not recommended that you configure a unit as a Trunk Link with the VLAN ID - Management parameter set at 65535, as it does not forward any ‘NO VLAN’ management frames to its other port making it impossible to manage devices connected behind the unit that are also configured with ‘NO VLAN’. BreezeACCESS VL System Manual 5-44 If the VLAN Forwarding option is enabled, a data frame received with a VLAN ID that is not a member of the unit’s VLAN Forwarding List is discarded. NOTE If the VLAN Forwarding option is enabled, be sure to include the VLAN ID - Management value of all units that should be managed via the wireless port of the unit, in the Forwarding List. If the VLAN Relaying option is enabled in an AU, a data frame relayed with a VLAN ID that is not a member of the unit’s VLAN Relaying List is discarded. NOTE If the VLAN Relaying option is enabled and you manage your devices from behind an SU unit, be sure to include the VLAN ID - Management value of all units to be managed when relaying via the wireless port of the AU unit, in the Relaying List. If the VLAN Forwarding option is also enabled in the AU, these VLAN IDs should also be included in the Forwarding List. Table 5-8 summarizes the functionality of the data port for a Trunk link. Table 5-8: VLAN Data Port Functionality – Trunk Link Action Data Port (SU and AU) Accept from Ethernet Tagged frames. If Forwarding is enabled, only frames with VLAN ID values which are included in the Forwarding list Accept from Wireless Tagged frames. If Forwarding is enabled, only frames with VLAN ID values which are included in the Forwarding list Tag Insert No Tag Remove No Operation and Administration 5-45 Hybrid Link Hybrid Link transfers both tagged and untagged frames, since the devices connected to the unit can be either VLAN-aware or VLAN-unaware. This is equivalent to defining no VLAN support, as the unit is transparent to VLAN. Table 5-9 summarizes the functionality of the data port for a Hybrid link. Table 5-9: VLAN Data Port Functionality – Hybrid Link Action Data Port (SU and AU) Accept from Ethernet All Accept from Wireless All Tag Insert No Tag Remove No VLAN Forwarding (AU and SU) The VLAN Forwarding feature is applicable for Trunk Links only. It enables defining the VLAN ID values to be included in the VLAN Forwarding List. If the Link Type is defined as a Trunk Link and the VLAN Forwarding option is enabled, a data frame received with a VLAN ID that is not a member of the unit’s VLAN Forwarding List is discarded. The VLAN Forwarding submenu provides the following options: VLAN Forwarding Support The VLAN Forwarding Support option enables or disables the VLAN Forwarding feature. Available selections are Disable and Enable. The default selection is Disable. Add Forwarding VLAN ID The Add Forwarding VLAN ID option enables adding a VLAN ID to the VLAN Forwarding List. One VLAN ID can be entered at a time. The maximum number of VLAN IDs in the VLAN Forwarding List is 20. Valid values are 1 to 4094. Remove Forwarding VLAN ID The Remove Forwarding VLAN ID option enables removing a VLAN ID from the VLAN ID Forwarding List. Valid values are VID values (from 1 to 4094) that are included in the VLAN Forwarding List. BreezeACCESS VL System Manual 5-46 Show VLAN ID Forwarding List The Show VLAN Forwarding List option displays the values of the VLAN IDs included in the VLAN Forwarding List. NOTE: If the VLAN ID Forwarding List is empty and the VLAN Forwarding Support is set to Enable, then all data frames are discarded. VLAN Relaying (AU only) The VLAN Relaying feature is applicable for Trunk Links only. It defining the VLAN ID values to be included in the VLAN Relaying List. If the Link Type is defined as Trunk Link and the VLAN Relaying Support option is enabled, a frame relayed from the wireless link, which is a frame received from the wireless link that should be transmitted back through the wireless link, with a VLAN ID that is not a member of the unit’s VLAN Relaying List, is discarded. If VLAN Forwarding Support is also enabled, it is necessary to configure all the VLAN IDs in the Relaying List also in the Forwarding List to enable the relaying operation. The VLAN Relaying menu provides the following options: VLAN Relaying Support The VLAN Relaying Support option enables or disables the VLAN Relaying feature. Available selections are Disable and Enable. The default selection is Disable. Add Relaying VLAN ID The Add Relaying VLAN ID option enables adding a VLAN ID to the VLAN Relaying List. One VLAN ID can be entered at a time. The maximum number of VLAN IDs in the VLAN Relaying List is 20. Valid values are 1 to 4094. Remove Relaying VLAN ID The Remove Relaying VLAN ID option enables removing a VLAN ID from the VLAN ID Relaying List. Valid values are VID values (from 1 to 4094)) that are included in the VLAN Relaying List. Operation and Administration 5-47 Show VLAN ID Relaying List The Show VLAN Relaying option displays the values of the VLAN IDs included in the VLAN Relaying List. NOTES: If the VLAN ID Relaying List is empty and the VLAN Relaying Support is Enabled, then all data frames relayed from the wireless link are discarded. If VLAN Relaying Support and VLAN Forwarding Support are both enabled, then all VLAN IDs configured in the Relaying List must also be configured in the Forwarding List. VLAN Traffic Priority Each packet to be transmitted to the wireless link is transferred to one of three queues: Low, Mid and High. Packets in the High queue have the highest priority for transmission, and those in the Low queue have the lowest priority. BreezeACCESS Subscriber and Access units support layer 2 traffic prioritization according to the IEEE 802.1p standard. The priority field in the 802.1Q header tag can have a value in the range 0-7. This value determines the relative priority of the packet. Packets received from the Ethernet port that have a Priority higher than the value of the VLAN Priority Threshold are routed to the Mid queue. Since the system also supports layer 3 prioritization, based on ToS, packets with precedence in the ToS field higher than the value of the ToS Precedence Threshold parameter are also routed to the Mid queue. This is applicable to both tagged and untagged frames. All other packets received from the Ethernet port are routed to the Low queue. Control and wireless management frames generated in the unit are routed to the High queue. Any frame coming from the Ethernet port, which is meant to reach another BreezeACCESS unit via the wireless port, is sent to the High queue, regardless of the priority configuration. The VLAN Traffic Priority menu provides the following parameters: VLAN Priority – Data (SU only) BreezeACCESS VL System Manual 5-48 The VLAN Priority – Data is applicable for Access Links only. It enables configuring the value of the VLAN Priority field for data frames transmitted to the wireless link. All data frames are routed to the Low queue. This parameter only impacts the way that other VLAN-aware devices handle the packet. Valid values range from 0 to 7. The default value is 0. NOTE: Packets Received from the Ethernet port with a ToS Precedence value higher than the defined ToS Precedence Threshold are routed to the Mid queue. VLAN Priority – Management The VLAN Priority – Management enables defining the value of the VLAN Priority field for management frames in units with VLAN ID - Management that is other than 65535. All management frames are routed to the High queue. This parameter only impacts the way other VLAN-aware devices handle the packet. Valid values range from 0 to 7. The default value is 4 for SUs and 0 for AUs. VLAN Priority Threshold The VLAN Priority Threshold is applicable for Trunk and Hybrid Links only. It enables defining the value of the VLAN Priority Threshold. This parameter impacts the way the unit handles tagged packets received from the Ethernet port. Since the system supports both layer 2 and layer 3 prioritization, a frame is routed to the Mid queue if either of the following conditions are met: ♦ The precedence in the ToS field is higher than the value of the ToS Precedence Threshold parameter. This is applicable to both tagged and untagged frames. ♦ The VLAN Priority field in a tagged frame is higher than the value of the VLAN Priority Threshold parameter. Valid values range from 0 to 7. The default value is 3. Show VLAN Parameters The Show VLAN Parameters option displays the current values of the VLAN support parameters. Operation and Administration 5-49 ToS Priority The ToS Priority menu enables configuring voice priority parameters to support end-to-end IPv4 Type of Service (ToS) layer 3 prioritization according to RFC 791. The ToS Priority menu includes the following parameter: ToS Precedence Threshold The ToS Precedence Threshold parameter enables defining ToS-based prioritization in accordance with the precedence bits of the ToS field in the IP header. An IP packet received from the Ethernet port is routed to the Mid queue if any one of the following conditions is met: ♦ The precedence in the ToS field is higher than the value of the ToS Precedence Threshold parameter. This is applicable to both tagged and untagged frames. ♦ The VLAN Priority field in a tagged frame (Hybrid or Trunk Link) is higher than the value of the VLAN Priority Threshold parameter. All other packets received from the Ethernet port are routed to the Low queue. Valid values are 0 to 7. The default value is 3. Ethernet Broadcast Filtering (SU only) The Ethernet Broadcast Filtering menu enables defining the layer 2 (Ethernet) broadcast and multicast filtering capabilities for the selected SU. Filtering the Ethernet broadcasts enhances the security of the system and saves bandwidth on the wireless media by blocking protocols that are typically used in the customer’s LAN but are not relevant for other customers, such as NetBios, which is used by the Microsoft Network Neighborhood. Enabling this feature blocks Ethernet broadcasts and multicasts by setting the I/G bit at the destination address to 1. This feature should not be enabled when there is a router behind the SU. The Ethernet Broadcasting Filtering menu enables configuring the following parameters: Filter Options The Filter Options enables defining the Ethernet Broadcast filtering functionality of the unit. Select from the following options: ♦ Disable, which means no Ethernet Broadcast Filtering. ♦ From Ethernet Only, which filters broadcast messages received from the Ethernet port. BreezeACCESS VL System Manual 5-50 ♦ From Wireless Link Only, which filters broadcast messages received from the wireless link port. ♦ Both From Ethernet & Wireless Link, which filters broadcast messages received from both the Ethernet and wireless link ports. The default selection is Disable. DHCP Broadcast Override Filter The DHCP Broadcast Override Filter option enables or disables the broadcasting of DHCP messages. Even if according to the selected option in the Filter Options parameter, broadcast messages should be filtered, DHCP broadcasts are transmitted if this parameter is set to Enable. Select from the following options: ♦ Disable, which means that DHCP Broadcast messages are filtered or transmitted according to the general filtering criteria in the Filter Options parameter. ♦ Enable, which means that DHCP Broadcast messages are transmitted regardless of the selected value of the Filter Options parameter. The default selection is Disable. PPPoE Broadcast Override Filter The PPPoE Broadcast Override Filter option enables or disables the broadcasting of PPPoE (Point to Point Protocol over Ethernet) messages. Even if according to the selected option in the Filter Options parameter, broadcast messages should be filtered, PPPoE broadcasts are transmitted if this parameter is set to Enable. Select from the following options: ♦ Disable, which means that PPPoE Broadcast messages are filtered or transmitted according to the general filtering criteria in the Filter Options parameter. ♦ Enable, which means that PPPoE Broadcast messages are transmitted regardless of the selected value of the Filter Options parameter. The default selection is Disable. ARP Broadcast Override Filter The ARP Broadcast Override Filter option enables or disables the broadcasting of ARP messages. Even if according to the selected option in the Filter Options parameter, broadcast messages should be filtered, ARP broadcasts are transmitted if this parameter is set to Enable. Select from the following options: ♦ Disable, which means that ARP messages are filtered or transmitted according to the general filtering criteria in the Filter Options parameter. Operation and Administration ♦ 5-51 Enable, which means that ARP messages are transmitted regardless of the selected value of the Filter Options parameter. The default selection is Enable. Bridge Aging Time The Bridge Aging Time parameter enables selecting the bridge aging time for learned addresses of devices on both the wired and wireless sides, not including BreezeACCESS VL units. The available range is 100 to 2000 seconds. The default value is 300 seconds. Broadcast Relaying (AU only) The Broadcast Relaying option enables selecting whether the unit performs broadcast relaying. When the Broadcast Relaying parameter is enabled, broadcast packets originating from devices on the wireless link are transmitted by the AU back to the wireless link devices, as well as to the wired LAN. If disabled, these packets are sent only to the local wired LAN and are not sent back to the wireless link. Disable the broadcast relaying only if all broadcast messages from the wireless link are certain to be directed to the wired LAN. The default selection is Enable. Unicast Relaying (AU only) The Unicast Relaying option enables selecting whether the unit performs unicast relaying. When the Unicast Relaying parameter is enabled, unicast packets originating from devices on the wireless link can be transmitted back to the wireless link devices. If disabled, these packets are not sent to the wireless link even if they are intended for devices on the wireless link. Disable the Unicast Relaying parameter only if all unicast messages from the wireless link are certain to be directed to the local wired LAN. The default selection is Enable. Show Bridge Parameters The Show Bridge Parameters option displays the current values of the Bridge parameters. BreezeACCESS VL System Manual 5-52 Performance Parameters The Performance Parameters menu enables defining a series of parameters that control the method by which traffic is transmitted through the BreezeACCESS VL wireless access network. The Performance Parameters menu provides the following parameters: RTS Threshold: The RTS Threshold parameter defines the minimum frame size that requires an RTS/CTS (Request To Send/Clear To Send) handshake. Frames whose size is smaller than the RTS Threshold value are transmitted directly to the wireless link without being preceded with RTS frames. Setting this parameter to a value larger than the maximum frame size eliminates the RTS/CTS handshake for frames transmitted by this unit. The available values range from 20 to 1600 bytes. The default value is 60 bytes for SUs and 1600 for AUs. It is recommended that these values be used to ensure that RTS/CTS is never used in the AU. Minimum Contention Window The Minimum Contention Window parameter determines the time that a unit waits from the time it has concluded that there are no detectable transmissions by other units until it attempts to transmit. The BreezeACCESS VL system uses a special mechanism based on detecting the presence of a carrier signal and analyzing the information contained in the transmissions of the AU to estimate the activity of other SUs served by the AU. The target is to minimize collisions in the wireless media resulting from attempts of more than one unit to transmit at the same time. The system uses an exponential Back-off algorithm to resolve contention between several units that want to access the wireless media. The method requires each station to choose a random number N between 0 and a given number C, and wait for this number of time slots before accessing the media, always checking if a different unit has access the media before. Each time the unit tried to transmit and a collision happened, the maximum number C used for the random number selection will be increased to the next available value. The available values are 7, 15, 31, 63, 127, 255, 511 and 1023. The Minimum Contention Window parameter is the first maximum number C used in the back-off algorithm. The higher the number of SUs served by the same AU, the higher the Minimum Contention Window for each SU should be. Operation and Administration 5-53 The available values are 7, 15, 31, 63, 127, 255, 511 and 1023. The default value is 15. Maximum Contention Window The Maximum Contention Window parameter defines the upper limit for the maximum number C used in the back-off algorithm as described in Minimum Contention Window above. The available values are 7, 15, 31, 63, 127, 255, 511 and 1023. The default value is 1023. Short Frame Multicast Rate (AU only) The Short Frame Multicast Rate parameter defines the rate of transmitting multicast and broadcast frames that are shorter than 500 bytes. Multicast and broadcast transmissions are not acknowledged; therefore if a multicast or broadcast transmission is not properly received there is no possibility of retransmitting. It is recommended that you set a lower rate for broadcast and multicast frame transmissions to increase the probability that they are received without errors. The available values for SU-A-54-VL are 6, 9, 12, 18, 24, 36, 48 and 54 Mbps. For SU-A-24-VL the available rates are 6, 9, 12, 18 and 24 Mbps. The default value is the lowest available rate, 6 Mbps. Long Frame Multicast Rate (AU only) The Long Frame Multicast Rate parameter defines the rate of transmitting multicast and broadcast frames with at least 500 bytes. Multicast and broadcast transmissions are not acknowledged; therefore if a multicast or broadcast transmission is not properly received there is no possibility of retransmitting. It is recommended that you set a lower rate for broadcast and multicast frame transmissions to increase the probability that they are received without errors. The available values for SU-A-54-VL are 6, 9, 12, 18, 24, 36, 48 and 54 Mbps. For SU-A-24-VL the available rates are 6, 9, 12, 18 and 24 Mbps. The default value is the lowest available rate, 6 Mbps. BreezeACCESS VL System Manual 5-54 Maximum Data Rate When the Rate Adaptation Algorithm is enabled, it changes the data rate dynamically according to link conditions to increase the probability of using the maximum possible rate at any given moment. Although the algorithm will avoid using rates that are too high for the prevailing link conditions, it might be desired under certain conditions to limit the use of higher rates. If the link quality is not sufficient, it is recommended that the maximum data rate be decreased, since higher data rate elevates the error rate. In such conditions, a higher data rate increases the number or retransmissions before the data rate is being reduced by the Rate Adaptation Algorithm. A high number of retransmissions reduce the overall throughput of the applicable SU as well as all other SUs associated with the same AU. The link quality can be estimated based on the SNR measurement of the SU at the AU, which can be viewed in the MAC Address Database option in the Site Survey menu. If the measured SNR is less than a certain threshold, it is recommended that the maximum data rate of the SU be decreased in accordance with Table 5-10, using the values of typical sensitivity. It is recommended to add a 2 dB safety margin to compensate for possible measurement inaccuracy or variance in the link quality. NOTE: The SNR measurement at the AU is accurate only when receiving transmissions from the applicable SU. If necessary, use the Ping Test utility in the Site Survey menu to verify data transmission. When the Rate Adaptation Algorithm is disabled, this parameter will serve to determine Fixed Data Rate for transmissions. Table 5-10: Recommended Maximum Data Rate SNR Maximum Data Rate SNR> 23 dB 54 Mbps 22dB < SNR< 23 dB 48 Mbps 18 dB< SNR < 22 dB 36 Mbps 14 dB < SNR < 18 dB 24 Mbps 11 dB < SNR < 14 dB 18 Mbps 9 dB < SNR < 11 dB 12 Mbps 7 dB < SNR < 9 dB 9 Mbps 6 dB .dwn to define the destination filename.

When the loading is complete, the following message is displayed: Download operation has been completed successfully 9. The FLASH memory can store two software versions. One version is called Current and the second version is called Shadow. The new version is loaded into the Shadow (backup) FLASH memory. To check that the new firmware was properly downloaded, view the firmware versions stored in the FLASH, as follows: a. From the Main Menu, select 2 – Unit Control. b. From the Unit Control menu, select 5 – Flash Memory Control. c. From the Flash Memory Control menu, select S – Show Flash Versions. The following information is displayed: Flash Versions =========== Running from Main Version Shadow Version :main version :au1_0_5.bz :au1_0_6.bz Configuration Download and Upload Using TFTP B-1 Appendix B Configuration Download and Upload Using TFTP The BreezeACCESS OFDM Configuration Download/Upload feature simplifies the task of remotely configuring a large number of units using TFTP protocol. By downloading the configuration file to a PC it is possible to view all the parameters configured for the unit, as a plain ASCII text file. It is necessary to edit the file using a simple editor and remove certain parameters or change their values prior to uploading the configuration to another unit. When multiple configurations are being done simultaneously, which means that the file is being uploaded to several units, it is recommended that the file only include the required parameters. In the configuration file, each parameter is represented by three fields: 1. A symbolic string similar to the name of the parameter in the Monitor program, followed by “=”. 2. The value of the parameters, which uses the same values as the Monitor program. 3. An optional comment. If used, the comment should start with a “;” character. An unknown parameter will be ignored. A known parameter with a value that is invalid or out-of-range will be set by the unit to its default value. Use the SNMP write community string (the default is private) to define both the uploaded file (put) and the downloaded file (get). Use the extension cfg for a configuration file. Use the extension cmr for the Operator Defaults file. The file should be transferred in ASCII mode. For Example: To upload the configuration file using a DOS based TFTP Client to an SU whose IP address is 206.25.63.65, enter: tftp 206.25.63.65 put Suconf private.cfg To download the Operator Defaults file from the same unit, enter: tftp 206.25.63.65 get private.cmr Suconf B-2 BreezeACCESS VL System Manual Preparing the Indoor to Outdoor SU Cable C-1 Appendix C Preparing the Indoor to Outdoor SU Cable The Indoor-to-Outdoor SU cable provides pin-to-pin connection on both sides. It is supplied open-ended at both sides, to allow the installer to conveniently route the cable into the waterproof seal off the Outdoor unit and through holes in walls. Figure C-1 shows the wire pair connections required for the Indoor-toOutdoor cable. Figure C-1: Ethernet Connector Pin Assignments Use a crimp tool for RJ-45 connectors to prepare the wires, insert them into the appropriate pins and use the crimp tool to crimp the connector. Make sure to do the following: 1. Remove as small a length as possible of the external jacket. Verify that the external jacket is well inside the service box to ensure good sealing. 2. Take back the shield drain wire before inserting the cable into the RJ-45 connector, to ensure a good connection with the connector’s shield after crimping.
