4.2.6.1.4.2 Access to DHCP
The Access to DHCP option enables defining the port through which the unit
searches for and communicates with a DHCP server. Select from the following
options:
From Wireless Link Only
From Ethernet Only
From Both Ethernet and Wireless Link
The default for Access Units is From Ethernet Only. The default for Subscriber
Units is From Wireless Link Only.
4.2.6.1.5 Show IP Parameters
The Show IP Parameters option displays the current values of the IP parameters,
including the Run Time IP Address, Run Time Subnet Mask and Run Time
Default Gateway Address.
4.2.6.2 Air Interface Parameters
The Air Interface Parameters menu enables viewing the current Air Interface
parameters defined for the unit and configuring new values for each of the
relevant parameters.
4.2.6.2.1 Country Code and Sub-Bands
Each country has its own regulations regarding operation modes and parameters
such as allowable frequencies and bandwidth, the need to employ an automatic
mechanism for detection and avoidance of frequencies used by radar systems,
maximum transmit power at each of the supported modulation levels and the
ability to use burst transmissions. To efficiently manage these country dependent
parameters, each unit has a ‘Country Code’ parameter and a set of accompanying
parameters, which depend on this country code. Where more than one set of
parameters can be used, the available sets are defined as Sub-Bands, selectable
through the Frequency configuration menu.
4.2.6.2.2 ESSID Parameters
The ESSID (Extended Service Set ID) is a string used to identify a wireless
network and to prevent the unintentional merging of two wireless networks or two
sectors in the same network. Typically, a different ESSID is defined for each AU.
To facilitate easy addition of SUs to an existing network without a prior
knowledge of which specific AU will serve it, and to support the Best AU feature,
a secondary "global" ESSID, namely "Operator ESSID", can be configured in the
AU. If the Operator ESSID Option is enabled at the AU, the Beacon frames
transmitted by it will include both the ESSID and Operator ESSID. The SU shall
