Overview
This device provides 30Channel telephone 1-4Channel E1 interface, 4Channel 10M/100M Ethernet
interface (Wire speed 100M) and 4 expansion interface. 4Channel 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.
