PROBLEM TO BE SOLVED: To provide a method for controlling the buffer memory of an ATM-Su for easily restoring an offset of a pointer even when the position of the pointer managing the buffer memory is offset due to noise or the like. SOLUTION: The control system for the buffer memory is a control system for a buffer memory in an Ethernet(R)-ATM converter. The buffer memory is a memory all the addresses of which are managed by a pointer. The control system is provided with a write address control section for controlling a write address to the buffer memory, and a read address control section for controlling a read address to the buffer memory. The head of packets is always written to the head address of the buffer memory in the case of writing packet data. COPYRIGHT: (C)2004,JPO
