Abstract
Each of a plurality of terminals in a two-way communications system includes a series of counters establishing a plurality of time slots synchronized to a downstream reference parameter. Upstream transmissions are effected by each terminal in one or more of the time slots which are defined by a downloaded message as comprising either a reserved slot or a contention slot. The downloaded message, which may also establish terminal transmission power levels and retransmission backoff algorithms for contention time slots, is derived on the basis of the population of subscriber terminals and the usage of the upstream channel.
