Hot sale E1 Converter - 8E1+4FE PDH Multiplexer JHA-CPE8F4 – JHA

8E1+4FE PDH Multiplexer JHA-CPE8F4

Overview

 This device  provides 1-8*E1 interface, 1-4*10M/100M Ethernet interface (Wire Speed 100M) and 2 expansion interface. 4* Ethernet interface is switch interface, 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 alarm function. The work is reliable, stable, and low power consumption, high integration, small size.
