PURPOSE:To prevent a waste of a buffer area by discriminating whether received data is long or short from its heading part and storing it in a corresponding buffer area. CONSTITUTION:A circuit control part 5 checks the bit constitution of the heading part (control part C) of the received data to discriminate between a monitor frame of short data and an information frame of long data, and reporting the result to a buffer control part 2. The control part 2 sends space area information on a buffer with long buffer length when the discrimination result shows the monitor frame or blank area information on the buffer with the long buffer length when the results shows the information frame according to the reported signal. The circuit control part 5 stores the received data in a corresponding buffer area in a storage part 1 on the basis of the supplied blank area information on the buffer. |
