8E1+4FE PDH Multiplexer | CLI and SNMP for Option

View : 602
Type : Optic 1+1 PDH Multiplexer
Description :

This device provides 1-8*E1 interface, 1-4*10M/100M Ethernet interface (Wire Speed 100M) and 2 expansion interface.


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