Network Management Support - 4K VLAN (IEEE 802.1Q), Port Base VLAN Support - 250msec Switching time in Ring topology This product can transmit 10/100/1000Mbps Ethernet data through 1 Core optical cable, and can be composed as such various networks as Point To Point, Linear Add/Drop and Ring. It has built-in by-pass function to automatically detour when the power supply is in trouble. Having Ethernet input and output display LED on the transmission and receiving part, it shows the communication state visually with no other devices. The 24 Ethernet ports can be extended without HUB. Management (N.M.S) system provides Graphic User Interface(GUI ) using LAN Interface, making it easy to maintain, repair and operate the system.
