4.2.6.2.13 Wireless Link Trap Threshold (AU only)
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 (%).
4.2.6.2.14 Country Code Learning by SU (AU only)
This feature supports simplified installation and updates processes by enabling
the SU to adapt the Country Code used by the AU.
The AU advertises its country code in every beacon and association response
message. Upon synchronization the SU shall check if its country code and the
country code received from the AU are the same. If they are not the same and the
Country Code Learning by the SU is enabled, the SU will use the AU’s country
code: the country code derived limitations will be forced and the following
parameters will be set according to the new country definitions:
 Maximum TX Power (per modulation level) will be set to the maximum defined
by the country code.
 TX Power (per modulation level) will be set to the maximum defined by the
country code.
 The Modulation Level will be set to the maximum modulation level defined by
the country code.
 The Multicast Modulation Level will be set to the minimum modulation level
defined by the country code.
 The Burst Mode will be set to enable if the country code supports burst mode,
and the burst duration will be set to default.
After country code learning (adaptation) the unit is automatically reset. Before
this automatic reset, if the unit is running from the shadow version, the versions
must be swapped and the running version must be set as main. This is done to
avoid returning to the previous version, which occurs automatically after the
reset.
The default is Enable.
