Adaptive Modulation: Check this box to enable the AN-80i to automatically adjust
the transmission modulation and code settings to achieve the highest UBR that will
operate with a packet error rate (PER at layer 2) of less than 1x10e-6. If the PER
exceeds 1x10e-6, the AN-80i automatically adjusts the modulation and code settings
downwards (i.e., from 16 QAM 3/4 to 16 QAM 1/2) to operate at a lower UBR where the
PER is acceptable. When disabled, the modulation and code settings are entered
manually using the Uncoded Burst Rate setting. See Table 4: Maximum TX Power
Settings (dBm).
Modulation Reduction Level: Enter the number of modulation/coding levels to step
down during re-transmission of errored wireless packets. Each step down lowers the
UBR. The level can be set from 0 to 7 (recommended value = 2).
Uncoded Burst Rate [Mb/s]: Select the desired UBR for the link. If Adaptive Modulation
is disabled, the AN-80i will transmit using only the specified settings. See Table 4:
Maximum TX Power Settings (dBm).
Channel Width [MHz]: Select the channel bandwidth. Refer to Table 51: Spec. -
Regional Identification Codes on page 92 for available channel widths.
Ethernet Follows Wireless: Check this box
to have the AN-80i disable and enable
the Ethernet port function based on the status of the wireless interface. This feature
allows switches and routers to trigger configuration changes based on changes to the
AN-80i Ethernet port status.
Disabled (
): The AN-80i Ethernet port is always enabled.
Enabled (
):Ethernet port is controlled based on the status of the wireless interface.

Important: The Ethernet Follows Wireless setting affects all data and management
traffic (HTTP, TELNET, and SNMP). While activated, it is not
possible to manage the
AN-80i using the Ethernet port.
Ethernet follows wireless timeout [sec]: Enter the period (in seconds) the Ethernet
port will remain disabled following loss of connectivity on the wireless interface.
Following this interval, the Ethernet port will be automatically re-enabled to allow
management of the AN-80i.
Important: When Ethernet Follows Wireless Timeout is enabled, external
switches/routers monitoring the Ethernet port must be programmed to not
switch
automatically when the Ethernet port function is restored -- the wireless interface may
not
be operational.
System Mode: Set the operating mode for each AN-80i system.
PTP Master: This unit begins transmitting automatically; sends poll messages to the
remote AN-80i, and negotiates the wireless link.
PTP Slave: This unit waits passively, monitoring the selected channel(s) until polled
by the PTP Master, and participates in negotiating the wireless link.
Software Version: Select the version of system software to load when the AN-80i is
rebooted. The system holds two independent software images.
