The Burst Controller monitors statistics in the received ACK from each Remote.
The statistics report the fill status of the STDMA buffers. The Burst Controller
builds a table of the group and calculates the relative buffer fill for each Remote.
It then calculates the length of the Data Slot for each Remote based on the Mini-
mum Slot Size plus a percentage of the Available Bandwidth. Idle remotes
would receive a Data Slot equal to the Minimum Slot Size.
