Default value is 48.
4.2.6.2.10 Wireless Link Trap Threshold
The Wireless Link Trap Threshold parameter defines the threshold for the wireless
quality trap, indicating that the quality of the wireless link has dropped below (on
trap) or has increased above (off trap) the specified threshold.
The Wireless Link Trap Threshold is in percentage of retransmissions, and the
allowed range is from 1 to 100 (%).
The default is 30 (%).
4.2.6.2.11 Spectrum Analysis
Gaining knowledge of the noise characteristics per channel enables construction
of a relatively noise free working environment. In order to gain information
regarding noise characteristics in the location of the unit, the unit will enter
passive scanning mode for a definite period, during which information will be
gathered. The scanned channels will be the channels comprising the selected sub
set.
Upon activating the spectrum analysis the unit will automatically reset. During
the information-gathering period the unit will not receive nor transmit data. It also
will not be able to synchronize/associate, meaning that it cannot be managed via
the wireless link. At the end of the period the unit will reset automatically
regaining normal operability upon start up.
The Spectrum Analysis submenu includes the following options:
NOTE
The Maximum Number of Associations must be set to a value of 124 or lower to enable Data
Encryption. As long as Data Encryption is enabled, the Maximum Number of Associations cannot
be set to a value higher than 124.
The Maximum Number of Associations Limit (512 when Data Encryption is disabled, 124 when Data
Encryption is enabled) is indicated in the Show Air Interface Parameters display.
NOTE
There is no aging time for SUs. An SU is only removed from the list of associated SUs under the
following condition:

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. To delete
inactive SUs from the database you must either disassociate them or reset the AU.
