The General tab is comprised of the following components:
 Band: A read-only field that displays the frequency band of the selected unit.
 Arbitration IFS: The Arbitration Inter-Frame Spacing. Defines the typical
minimum time (DIFS) between consecutive transmissions. The available
options are:
 1 Slot
 2 Slots
A value of 1 should be used only in point-to-point applications to define the
unit that should have advantage over the other one.
NOTE
The AIFS parameter is not applicable when the Wireless Link Prioritization Option is enabled.
 Antenna Gain: The net gain of the antenna, including attenuation of the RF
cable, to be used for calculating the maximum permitted transmit power
where there are limitations set by local regulations. In certain units with an
integral antenna the value is pre-configured at the factory and cannot be
changed. A value of Not Set Yet indicates that the actual value must be
entered (as long as the value remains Not Set Yet the unit will not transmit). A
value of Don’t Care means that there are no transmit power limitations.
The configurable range is 0 to 50.
 Maximum Number of Associations (AU only): The maximum number of
Subscriber Units that can associate with the selected Access Unit. The
available values range from 0 to 512.
 Maximum Num of Associations Limit (AU only): The Maximum Number of
Associations parameter defines the maximum number of Subscriber Units
that can be associated with the selected AU, while still guaranteeing the
required quality of service to customers.
Available values for AU-BS and AU-SA range from 0 to 512. For AUS-BS and
AUS-SA the range is from 0 to 8. For AUS-BS and AUS-SA that were upgraded
to support up to 25 SUs, the range is from 0 to 25. When data encryption is
enabled, the maximum number of SUs that can be served by AU-BS or AU-SA
is 124.
