<p><P>PROBLEM TO BE SOLVED: To monitor the amount of data transmitted from a data processor to an exchanger, detect abnormality of the data processor, and store data of the data processor in a monitor device. <P>SOLUTION: If data processors 301, 302 and 303 transmit an abnormal amount of data, data abnormality decision parts 201, 202 and 203 output data abnormality signals. When receiving the data abnormality signal, a controller 103 controls a signal path of a switch main body 102, and disconnects the signal path of the data processor which transmits the abnormal amount of data from the other data processors to connect it to an ATM cell monitor device 401. The ATM cell monitor device 401 stores data in a buffer part 403 when an error occurs. When the amount of data becomes normal, connection of the data processors 301, 302 and 303 is recovered in the switch main body 102. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
