Abstract
PURPOSE:To perform high-speed burst-like data switching without using a processor by adding a switch control bit to the head field of date, and controlling a multistage switch by using this control bit. CONSTITUTION:The data, to which the switch control bit is added at its head field, is inputted to ID1, ID1+1. In a switch control circuit SWC, block transfer data which is outputted through header processing circuits IH1-IH2 is given to a digital space division switch SDSW according to the detection output of the header processing circuits IH1-IH2 and the switch state signal of the switch element SE of a rear stage. The SDSW selects successively a destination channel by using the control bit. In this case, when the switch stage of the SDSW is in a busy state, the transfer data is stored once in buffers BUF1, BUF2, and after waiting an idle state, is given to the switch of the rear stage.
