Set the TX/RX Throughput Ratio (%) parameter to program radio symmetry. The default setting is
50/50 for symmetrical, full-duplex throughput. Other throughput ratio options are 20/80, 80/20,
and 65/35, 35/65. See Link Symmetry
.
For asymmetric throughput, only TDD frame size settings of 2ms and 5ms and RF Bandwidth
settings of 16MHz and higher are supported. The 64MHz/Mode2 configuration does not support
asymmetry due to capacity limitations of the 100BaseT interface.
Radio Collocation enables the Sync feature. See Radio Synchronization.
The External Alarm Inputs parameter can be ignored unless connecting external alarm sources to
the radio for monitoring the status of these external alarms through the radio management system
(see Interface Connections
).
Aggregate User Throughput parameter provides information about user capacity of the wireless
link, in the current configuration. The ‘new value’ column reflects throughput if changes are made
to Bandwidth, Mode, Link Distance, and/or TDD Frame Size. Click the “Aggregate User
Throughput” link for details on aggregate capacity.
Note: Changing the TDD Frame Size parameter will temporarily interrupt traffic. TDD
Frame Size parameters must match at each end. Adjust the far-end radio first, and then the
near-end radio. If the TDD Frame Size parameter is set to a value that cannot be supported for
the link distance, 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.
