to a setting that is less than the actual distance there is an opportunity that the link
may be lost and unrecoverable through GUI control. If the link is lost due to this
situation, travel to the radio location(s) may be required to reset the value. If the Link
Distance setting is set to a distance that is unnecessarily higher than the actual link
distance, the radio may have substantially reduced performance with respect to
throughput and latency.
• TDD Frame Size must be set to the designed level. The value of this setting should
have been determined in the design/engineering stage. The TDD Frame Size must also
match at both ends of the link. The TDD Frame Size setting directly relates to the
capacity, latency and the number of TDM circuits that can be supported over the given
link distance. In multi-link networks, especially where there are collocated links, it
may also be important to set all radios to the same TDD Frame Size to avoid self-
interference. The (future) GPS or internal synch function may be necessary for these
types of networks. See sections 2.4 and 2.5 for more information.
Changing TDD Frame Size will temporarily interrupt traffic. The TDD Frame
Size must match at each end – adjust the far-end radio first, then the near-end radio.
If the TDD Frame Size is set to a value that cannot be supported for the link distance,
there is an opportunity that the link may be lost and unrecoverable through GUI
control. If the link is lost due to this situation, travel to the radio location(s) may be
required to reset the value.

The Ethernet Interface Configuration Page allows the administrator to set the alarming and
duplex settings of the Ethernet connection.
Depending on the connected equipment, optimum Ethernet performance may be achieved by a
variety of combinations of speed/duplex settings. That is, the system may perform best if both
