Abstract
PURPOSE: To make it possible to monitor even a high-speed circuit by branching a line at the terminal device side of a line adapter to another line adapter and by making it possible to use line adapters as they are for monitoring.
CONSTITUTION: As for line adapters 6-0 and 6-3 connected to terminal devices 7, reception line 10R and transmission line 10S at terminal device sides are branched and connected to other line adapters 6-1, 6-2, 6-4, and 6-5. When data transmission and reception are performed between data buffer area 15-0 and terminal device 7-0 via line adapter 6-0, those data are branched to and received by line adapters 6-1 and 6-2 and written in data buffer areas 15-1 and 15-2. Further, processor 1 is interrupted to dump the contents of buffer areas 15-1 and 15-2 to memory devices 8 and 9.
