16E1+LCD Display+SNMP PDH Multiplexer

View : 784
Type : 1-16E1 Fiber Multiplexer
Description :

The device provides 1-16*E1 interface, 1-4*10/100M Ethernet interface (Wire speed 100M) and 2 expansion interface.


This device has console control, it provides 1+1 fiber backup protection, point-to-point optical transmission, and LCD display. It is based on our company’s development of the PDH optical transmission and uses the special VLSI and the SNMP NMS.


The device provides 1-16*E1 interfaces, 1-4*10/100M Ethernet interfaces (Wire speed 100M), and 2 expansion interfaces. 4 Ethernet interfaces are switch interfaces, which can support VLAN. 2 expansion interfaces 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 and stable, it has low power consumption, high integration, and small size.
