32Voice(FXO/S) over FIBER MULTIPLEXER

Functions

This point to point fiber transmitting equipment, which is designed on large scale integrated circuit, realizes 1~4 E1 circuit, 1 ~4 channels 100M Ethernet, 32 channel voice (FXO, FXS) and 1~4 channel RS232. The device support two optical fiber port (1+1 protection). Its merits include complete warning function, high integration, low consumption, stable performance and convenient usage.
