mutil-service voice over fiber mux

16FXO/FXS +4E1+4FE +4RS232/422/485 Fiber Multiplexer with Optional Console/SNMP fiber(1+1) redundancy

This device provides 16Channel telephone1-8Channel E1 interface 4Channel 10M/100M/1000M Ethernet interface (Wire Speed 100M/1000M) and 4 expansion interface. 4Channel Ethernet interface is switch interface can support VLAN. 4 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.
