Overview
This device provides 1-4Channel E1 interface, master optical fiber
interface and backup optical fiber interface, 1-4Channel 10M/100M
Ethernet interface (Line Rate 100M) and 2 expansion interface.
4Channel 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.
