!
Acknowledge Delay Limit – Increases the range of the system
through increasing the time that the unit can wait for
acknowledgements. Increasing the range, however, may decrease
the overall performance and achievable network throughput. It
should be increased only to support ranges of over 10 km. If the
range was increased for one SU, it must be increased to the same
value for the AU.
Valid values are: Low (up to 10 km), Medium (up to 20 km) and High
(more than 20 km).
The default setting is Low (up to 10 km).
! Maximum Number of AssociationsDefines the upper limit for
the number of Subscriber Units that can be associated with the AU,
in order to guarantee the required quality of service to the
customers.
Valid values: 0-512.
Default value: 512.
! WLAN Aging Time (AU only)– Displays the current Call Aging
Time parameter value and configures a new value. The AU
maintains a Call Information database that includes listings of the
SUs that are currently conducting a voice call. This database is used
to determine the number of active voice calls that are managed by
the AU at any given moment, allowing control of the number of
simultaneous voice calls (see Maximum Voice Sessions
parameters). In addition, the AU allocates prioritized channels to the
voice (RTP) packets of SUs included in the Call Information
database.

NOTE:
There is no aging time for SUs. An SU will be removed from the list of associated SUs
only upon occurrence of any of the following: (1) The AU received from another AU a
SNAP frame with the SU MAC address indicating that the SU has become associated
with the other AU, or (2) The AU has decided that the SU aged out following its failure
to acknowledge a certain number of consecutive frames transmitted to it.
Thus, the database of associated SUs may include units that are no longer associated
with the AU. If the number of associated SUs has reached the value of the Maximum
Number of Associations parameter, additional SUs can not be served by this AU. To
view the current number of associated SUs, use the Display Association Info option
in the MAC Address Database menu. To delete entries of SUs that are no longer active,
the AU must be reset.
