Abstract: A fairness protocol circuit for a token ring local area network adaptor having a data-in line for serially carrying tokens/frames and a shift register delay of at least 18 bauds with an input coupled to the data-in line. A TTT stack is coupled to the shift register delay for serially storing values of old token indicators. An III stack is provided for serially storing values of new token priority indicators. TTT means is coupled to the TTT stack for temporarily storing a last old token placed on the TTT stack and serially outputting its bits. The stacks shift up or down bit by bit in response to UNSTACK or STACK control signals and are cleared in response to a clear signal.
