Abstract

PURPOSE:To transfer the information stored at the end of daily job to a processing device, by storing the number of frames transmitted and received in the unit of receive delay frame and information frame and the like. CONSTITUTION:A processing section 11 discriminates that the number of received frames from a line 20 is I, +1 is added to the content in the I frame reception count area in a storage circuit 12. When the processing section 11 discriminates that the transmission of an RR frame is required for the I frame reception, the RR frame is formed and +1 is added to the content of an RR frame transmission count area of the storage circuit 12 at each formation. At the end of daily job, a processor reads the content of the storage circuit 12 and logs the content as daily information.
