4E1+4FE 1+1 PDH Multiplexer

Overview
This device  provides 1-4Channel E1 interface master optical fiber interface and backup optical fiber 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.
Features
◆ based on self -copyright  IC;
