NOTE
The Maximum Number of Associations parameter in AU-BS or AU-SA may be configured to a value
that is higher than the actual limit (124) when data encryption is enabled.
 Wireless Trap Threshold (AU only): The threshold for sending the AU
Wireless Quality Trap, which indicates that the quality of the wireless link has
dropped below (off), or has increased above (on), the specified threshold. The
Wireless Trap Threshold is in percentage of retransmissions compared to
total transmissions. The range is from 1% to 100%.
 Scanning Mode (SU only): Defines whether the SU will use Passive or Active
scanning when searching for an AU. When DFS Option is enabled, Scanning
Mode is forced to Passive.
 Country Code Learning by SU (AU only): Defines whether the SU should
learn the country code advertised by the AU, and use the parameters of the
advertised country code if it differs from the one configured in the SU.
 Beacon Watchdog (AU only): When it is not able to send beacon frames for a
predetermined number of beacons, such as in the case of interferences, an AU
resets itself. The Beacons Watchdog parameter represents the number of
consecutive lost beacons, after which the unit will reset itself.
The range is from 100 to 1000 (lost beacons). When the parameter is set to 0,
or when the check box next to it is not marked, this feature is disabled, i.e AU
internal refresh will never be performed.
2.4.1.1 Cell Distance Parameters
 Cell Distance Option (AU only): Defines whether the maximum distance of
the AU from any of the SUs it serves will be determined manually (using the
Maximum Cell Distance parameter) or automatically.
 Max Cell Distance: The distance from the AU of the farthest SU served by it.
Configurable only in AU, and only if the Cell Distance Option is set to Manual;
otherwise it is read-only. The Max Cell Distance affects the maximum time
that the AU and all units served by it unit will wait for a response message
(including Acknowledgements of unicasts and response messages during the
authentication and association process). This parameter also affects the size
of time slots, to ensure fairness in the contention back-off algorithm between
SUs located at different distances from the AU.
The available values are 1 to 54 (kilometers) or 0 for no compensation
(minimum slot size, maximum time-out when expecting a response message)
