INFORMATION

Overview

 This device provides 1Channel telephone， 1-4*Channel E1 interface, 4*Channel 10M/100M Ethernet interface (Wire Speed
100M) and 4 expansion interface. 4*Channel Ethernet interface is switch
interface, can support VLAN. 4 expansion interface can be used as the
transmission channel of RS232/RS485/RS422 asynchronous data, voice signal, 2/4
line E&M audio signal, switch signal, Ethernet signal (Bandwidth 2M). It is
very flexible.
