Overview
This device provides 1-4 Channel E1 interface, master optical fiber interface and
backup optical fiber interface, 1-4 Channel 10M/100/1000M Ethernet interface (Line Rate 1000M) and
2 expansion interface. 4 Channel Ethernet interface is switch interface, can
support VLAN. 2 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. It has alarm function. The
work is reliable, stable, and low power consumption, high integration, small
size.
