Product Description
  This device is the point-to-point optical transmission device developed on the basis of VLSI. The device  provides 1-32*E1 interface, 1-4*10/100/1000M Ethernet interface (Wire Speed 1000M) and 2 expansion interfaces. 4* Ethernet interface is switch interface, can support VLAN. 1 expansion interface can be used as the transmission channel of RS232/RS485/RS422 asynchronous data, dry contact signal, 1Channel digital business phone can be optional. It is very flexible. It has alarm function. The work is reliable, stable, and low power consumption, high integration, small size.
