Overview
This device is the point-to-point optical transmission device
developed on the basis of VLSI. The device provides 1-8Channel E1 interface, 1-4Channel 10M/100M/1000M Ethernet interface
(Line Rate 1000M) and 2 expansion interfaces. 4Channel Ethernet
interface is switch interface, can support VLAN. 1 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).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.
