Product Description

SM-120NET-16M   PDH optical fiber transmission on the basis of special-purpose VLSI development point to point optical transmission device.

It provides 1-16Channel E1 interface, 1-4Channel 10M/100M Ethernet interface (Line Speed 100M) and 2 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 is very flexible to management with snmp, console, telnet and alarm function.

The work is reliable, stable, and low power consumption, high integration, small size, easy of installation and maintenance
