16E1+4FE 1+1 Fiber Backup PDH Multiplexer

This device provides 1-16*E1 interface, 1-4*10M/100M Ethernet interface (Wire Speed 100M) and 2 expansion interface. 4* Ethernet interface is a switch interface, that can support VLAN. 2 expansion interface can be used as the transmission channel of RS232/RS485/RS422 asynchronous data. It is very flexible. It has an alarm function. The work is reliable, stable, and low power consumption, high integration, small size.
