16E1+4GE PDH Multiplexer

Product Description

This device is the point-to-point optical transmission device developed on the basis of VLSI. The device  provides 1-16Channel 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.
