PDH Multiplexer
DESCRIPTION
This device provides 1-4Channel E1 interface, master optical fiber interface and backup optical fiber interface, 1-4Channel 10M/100M Ethernet interface (Line Rate 100M) and 2 expansion interface. 4Channel Ethernet interface is switch interface, can support VLAN. 2 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.
FEATURES
n 1+1fiber line protection: double port protection.When one of the fiber failure, can be guaranteed without interruption of service;
n Provides 8 E1 transparent transmission ;
n Provide Console manage interface(RS232)
n Provide4*10/100M line Ethernet channel,support mutual negotiate, Ethernet bandwidth is set on base on multiple of 32K.;
n Provide one hot-line channel for option;
n The rate of optical port is 155/350Mbps, transmission range can reach 25KM, 40KM, 60KM, 80KM or 120KM;
