Turning Copper into Gold
1：Overview
This device is a kind of developed point to point transmission equipment based
on our company PDH fiber transmission the special-use VLSI. This device
provides 16 Channel EM2/4 1-4Channel E1 interface, 4Channel 10M/100M
Ethernet interface (Line Speed 100M) and 1 expansion interface. 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). It has alarm function. The working is reliable, stable, and low
power consumption, high integration, small size, ease of installation and
maintenance.
