Abstract
The data communications systems disclosed herein accommodates terminals having different throughput capabilities by flexibly allocating cyclicly rotated phases of a common pseudo-noise (P/N) code. Throughput capabilities of the terminals are expressible in multiples of a preselected minimum throughput rate so that a single respective code phase is assigned to any terminal operating at the minimum throughput rate while a plurality of sequential consecutive phases are assigned to each terminal having a capability greater than the minimum throughput rate. One or more unassigned phases are provided between phases assigned to different terminals. Any terminal operating at the minimum throughput rate utilizes all time slot intervals in a predetermined frame interval while terminals of greater capability are assigned time slots in accordance with the amount of data traffic to be carried by that terminal and the number of code phases assigned thereto.
