Figure 4-6: 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
uplink Burst Error Rate counters. The information displayed for each
rate in uplink is the accumulated number since the last time the
counters were reset. For each rate the displayed information includes:
Total Burst
Error Bursts
Error Rate
The counters are reset each time the SU is reset, or upon activating the
Reset option.
