PDH Multiplexer

PDH/Voice Multiplexer

E1+ Fiber Ethernet PDH

  • Overview:

    This device is the point-to-point optical transmission device developed on the basis of VLSI. The device  provides 1-4*E1 interface, 1-4*10/100/1000M Ethernet interface (Wire Speed 1000M) and 2 expansion interfaces. 4* Ethernet interface is switch interface, can support VLAN. 1 expansion interface can be used as the transmission channel of RS232/RS485/RS422 asynchronous data, dry contact signal, 1Channel digital business phone can be optional. It is very flexible. It has alarm function. The work is reliable, stable, and low power consumption, high integration, small size.



    • Provide 2 expansion interface, you can extend 1~2Channel asynchronous data, such as RS232/RS485/RS422/Manchester code;
    • Provide command the remote interface Loop Back, support local E1 Loop Back function, support E1 LOS and AIS alarm ,ease line maintenance
    • The transmission distance is up to 2-100Km without interruption
    • Support SNMP manager (SNMP agent inside)
    • AC 220V, DC-48V, DC24V can be optional
    • DC-48V/DC24V power supply polarity detection function, Polarity-Free
