4.2.6.5.9.2 Minimum Interval Between Adaptive Modulation Messages

The Minimum Interval Between Adaptive Modulation Messages sets the minimum

interval between two consecutive adaptive modulation messages, carrying

information on the SNR of received signals. The messages in the AU include SNR

information on all the SUs associated with it.

The available range is from 1 to 3600 seconds.

The default is 4 seconds.

4.2.6.5.9.3 Adaptive Modulation Decision Thresholds

Enables selection between Normal and High decision thresholds for the Adaptive

Modulation algorithm. In links with a low SNR (below 13), the Adaptive

Modulation algorithm may not stabilize on the correct modulation level when

using the standard decision thresholds. In this case the algorithm may try to use

a modulation level that is too high, resulting in a relatively large number of

dropped frames. The “High” option solves this limitation and ensures good

performance also in links with a low SNR.

The default is Normal.

4.2.6.5.10 Concatenation Parameters

The Concatenation mechanism enables bundling several data frames into a single

frame for transmission to the wireless link. This feature improves throughput and

reduces the overhead in the wireless medium, by requiring only one CRC for each

concatenated frame, one RTS/CTS cycle if applicable, and a single waiting period

according to the contention window mechanism before transmission. When

concatenation is enabled, data packets in the queue of the internal bridge can be

accumulated before the concatenated frame is transmitted to the wireless

medium. Data frames can be accumulated up to a maximum frame size of 2200

bytes for units with HW revision A or B, or 4032 bytes for units with HW revision

C or higher. In the AU, the concatenation process is performed separately for

each destination SU.

NOTE

Using the Link Capability exchange mechanism, each unit learns the HW Revision and the SW

Version of the unit(s) associated with it. A concatenated frame with a length exceeding 2200 bytes

may be generated and transmitted only if both the source and destination units have HW Revision

C or higher. If either the source or destination unit uses SW Version 3.0 or 3.1, then the maximum

size of the concatenated frame is 3400 bytes, and the maximum number of data frames that can be

bundled into a concatenated frame is 2 for units with SW version 3.0 and 8 for units with SW

version 3.1.

A frame is a candidate for bundling into a concatenated frame if all the following

conditions are met:

Menus and Parameters In addition, the Wireless Link Prioritization, which is a licensable feature, enables to configure parameters that affect the prioritization of traffic in the wireless link for packets with high/low priority from different units. 4.2.6.6.3.1 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.
PAGE 10
Chapter 4 - Operation and Administration 4.2.6.6.3.2.3 DSCP Threshold The DSCP Threshold parameter is applicable when the ToS Prioritization Option is set to Enable DSCP (RFC2474) Prioritization. If the value of the 6 DSCP bits in the IP header is higher than this threshold, the packet is routed to the High queue. If the value is lower than or equal to this threshold, the packet will be routed to the Low queue (unless it is assigned a High priority by another classifier). Valid values range from 0 to 63.
PAGE 11
Menus and Parameters consecutive numbers: RTP port is always an even number, and the port with the odd number following it will be assigned to RTCP. If the administrator selects to prioritize only the RTP packets, then all the packets with an odd numbered destination port will always have Low priority. The packets with an even number for destination port will receive High priority, if the port number is included in the specified ranges.
PAGE 12
Chapter 4 - Operation and Administration destination is included in the list will be routed to the High queue. All other packets will be routed to the Low queue (unless they were assigned a High priority by another classifier). The TCP Port Ranges menu includes the following options: TCP RTP/RTCP Prioritization: Voice over IP is transported using Real Time Protocol (RTP). The Real Time Control Protocol (RTCP) is used to control the RTP.

A Appendi x A - Software Version Loading Using TFTP
PAGE 22
Appendix A - Software Version Loading Using TFTP Firmware upgrades to the unit's FLASH memory can be performed by a simple loading procedure using a TFTP application. Before performing an upgrade procedure, be sure you have the correct files and most recent instructions. Upgrade packages can be obtained from the Technical Support section of Alvarion's web site, http://www.alvarion.com/. CAUTION Shutting down power to the unit before completion of the loading procedure may cause the unit to be inoperable.
PAGE 23
Software Version Loading Using TFTP 7 The original sourcefile name of SW files is in the structure uX_Y_Z.bz, where u is the unit type (a for AU, s for SU) and X.Y.Z is the version number. 8 destinationfile is the name of the file to be loaded. Use the SNMP write community .bz to define the destination filename. The default SNMP write community is private. For example, to load the upgrade file a4_0_13.bz to an AU whose IP address is 206.25.63.65: tftp -i 206.25.63.65 put a4_0_13.

Appendix B - File Download and Upload Using TFTP The File 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.
PAGE 27
File Download and Upload Using TFTP Examples: 1 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 2 To download the Operator Defaults file from the same unit, enter: tftp 206.25.63.65 get private.cmr Suconf 3 To upload the Feature Upgrade file to the same unit, enter: tftp 206.25.63.65 put Suconf private.fln 4 To upload the Country Code file from to same unit, enter: tftp 206.25.63.

Appendix C - Using the Set Factory Defaults Utility The Set Factory Defaults utility is intended to enable management access to a unit in cases where such access is not possible due to wrong or unknown configuration of certain parameters. This includes cases such as unknown Management VLAN ID and wrong management access filtering. The utility accesses the unit by sending a special packet. Access to the unit is based on its MAC address, which must be entered in the Unit MAC address field.

Appendix D - Preparing the Indoor to Outdoor SU Cable The Indoor-to-Outdoor cable provides pin-to-pin connection on both ends. Figure 4-2 shows the wire pair connections required for the Indoor-to-Outdoor cable.
PAGE 33
Preparing the Indoor to Outdoor SU Cable 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.
