<p>PROBLEM TO BE SOLVED: To avoid the danger of safety as a result of overload at an exchange station when always providing high real data throughput at the exchange station by providing respectively specified detector and repeater. SOLUTION: An exchange station 1 is provided with a collator 11, detector 12 and multiplexer 13 and the collator 11 is connected through a lot of data transmission lines DI to the transmission station and the detector 12. Then, subdetectors from 12-1 to 12-n supply data packets received from the collator 11 through the data transmission line DW1 to the subdetectoes so that only data packets issued from respectively correspondent transmission stations can be supplied. The multiplexer 13 sends the data packets from the exchange station through a data transmission line D0 decided in advance. Thus, the exchange station can be always surley operated based on the joint operation of detector 12 and collator 11 without generating overload at the exchange station.</p> |
