32Voice+4E1+4FE+4RS232 Fiber Multiplexer

This device provides 32-channel telephone, 1-4 channels E1 interface, 4-channel 10M/100M Ethernet interface (Wire speed 100M), and 4 expansion interface. 4-Channel Ethernet interface is switch interface, which 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, and Ethernet signal (Bandwidth 2M). SNMP or Console management is optional. It is very flexible.

● Based on self-copyright IC
