Apparatus for outputting a signal, a method for outputting the signal, and a computer-readable storage medium storing a computer-executable program for operating a computer to output the signal

摘要

A counter of a transmission permitting signal counts a number of the transmission permitting signal which was not sent to a subscriber-side apparatus due to the opening of ranging window. A band controller allocates a band to the transmission permitting signal which was not sent so that the transmission permitting signal which was not sent and counted by the counter of the transmission permitting signal is sent prior to other signals in a next sending opportunity (next time frame for updating the band).
