Data Bytes Transmitted
: The total number of data bytes transmitted to
the Wireless link. MAC Management frames and frames with errors are not
included.
Data Bytes Discarded on Tx
: The number of bytes in packets discarded
due to congestion in the wireless medium.
ARQ Enabled Bytes Transmitted
: The number of bytes transmitted over
BE and NRT connections. Applicable only if the ARQ mechanism in the AU
is enabled.
Bytes Retransmitted
: The number of unacknowledged bytes that were
retransmitted. Retransmissions are applicable only to BE and NRT
connections, provided the ARQ mechanism in the AU is enabled.
Retransmission Rate (%)
: Retransmission Rate in percents is defined as:
100*(Bytes Retransmitted)/(ARQ Enabled Bytes Transmitted).

burst includes a CRC string.

Figure 4-3: Uplink and Downlink Scheduled Transmissions
In the downlink, each burst uses a single rate and may include data intended for
several SUs. In the uplink, each burst is from a different SU (also using a single
rate).
The Burst Error rate Counters option enables viewing or resetting the Burst Error
Rate counters. The information displayed for each rate in uplink and downlink is
the accumulated number since the last time the counters were reset. For each
direction (uplink/downlink) the displayed information includes the following
statistics for each rate:
Total Burst
Error Bursts
