SNMP Managed 16E1 PDH Multiplexer

Modular Integrated Optical Multiplexer

This device has the console control ，provides the 1+1fiber path protection ,point to point optical transmission, LCD display , on the basic of our company development of the PDH optical transmission, use the special VLSI and the SNMP NMS. The device provides 1-16Channel E1 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
