    8E1+4FE PDH Multiplexer

    Type:FCP-E8F4 Message

    Description:8E1+4FE PDH，order wire phones， 19\'\'inch 1U，（Standard telephones interface, non-telephones handles），Console

    Product Description
              This device  provides 1-8Channel E1 interface, 1-4Channel 10M/100M Ethernet interface (Line Rate 100M) and 2 expansion interface. 4Channel Ethernet interface is switch interface, can support VLAN. 1 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.
