Physical Isolation PDH Mux

16E1+4FE 1+1 PDH Multiplexer(Physical isolation)

This series of equipment is the company developed the PDH fiber transmission dedicated VLSI developed on the basis of point to point optical transmission equipment. Provide 1 to 16 E1 interfaces primary and backup fiber optical interface connector 1-4 physical isolation 10M / 100M Fast Ethernet interface (independent four-speed route 100M) as well as two business expansion interface. 2 Extended service interface can be used as RS232 / RS485 / RS422 asynchronous data voice signal twenty-four wire E & M audio signals digital signals Ethernet signals (bandwidth 2M) and other transmission channel the application is very flexible. Optional one digital service telephone the application is very flexible. With a sound alarm function the whole stable reliable low power consumption high integration small size.
