摘要: An ATM-ETHERNET converter (21B) is provided for relaying ATM cells (70) transmitted from a CLAD (22) of an ATM network (2B) to a CLAD (22) of an ATM network (2A) via a wide area Ethernet (3). The ATM-ETHERNET converter (21B) is provided with an ATM-PHY (212) receiving the ATM cells (70) transmitted from the CLAD (22) of the ATM network (2B), a buffer (41) storing the ATM cells (70) thus received, a LAN switch (214) that encapsulates the ATM cells (70) stored in the buffer (41) in a frame (FRD) corresponding to the wide area Ethernet (3) and sends the ATM cells (70) to the wide area Ethernet (3), and a CPU (211) starting discarding the ATM cells (70) stored in the buffer (41) at a predetermined time.
