Abstract

PURPOSE:To avoid the transmission right abandon signal from being stall conditioned on its way, by constituting the system that the timer is set with the transmission of transmission right abandon code and transmitting the transmission right abandon code with the timeout again. CONSTITUTION:The timer selection 1 selects the timer reset with the transmission of the transmission right abandon code EOT with the signal from the reception control. Further, the timers (1) and (2) are set with the signal from the timer selection 1 and if no confirmation code is received and detected for a given time, the constitution is made that the EOT code is again transmitted with timeout. Thus, the EOT code is avoided from being in stall condition on its way.
