NOTE: In TDM link optimization mode, burst duration should be selected so as to achieve the
lowest latency consistent with throughput sufficient to support the maximum allowed
configuration of internal TDM interfaces at the most robust modulation mode.
the frame duration thresholds for TDM operation. Frame duration depends on burst duration.
Burst duration should be selected by testing each of the values available in the applicable
bandwidth combination, starting with the shortest burst duration, until the resulting frame
duration falls within the limits listed in
