Abstract: A communication system includes data terminals (20-1 to 20-N) and controllers (10, 12, 16, 19). The controllers have distinct areas of data terminals. The controllers map data terminals to groups and grant transmission time to each group in turn by polling. The controllers map the terminals to groups having a minimum number equal to a single terminal (20-1), corresponding to straight polling, and a maximum number equal to the total number of terminals (20-n) in the system, corresponding to a singly-slotted ring, and dynamically change the group sizes and mappings in response to the system activity.
