Abstract
A method and apparatus for rotating priorities among stations on a communication channel, and particularly on a contention channel where a plurality of active stations are provided, each capable of seizing use of the channel. Counter means at each station contains an indication representative of the station having highest priority to the channel Each station establishes a priority rank for itself based upon the contents in the counter means. The indication is sequentially altered to provide priority to other stations. The priority indications in the counter means are synchronized each time a station seizes use of the channel, and may also be synchronized periodically if no station seizes use of the channel.
