Functions
The 16 voice (fxs/fxo) phone over fiber multiplexer is point to point fiber transmitting equipment, which realize 1~4 E1,4*10/100M Ethernet,16 channel voice (FXO, FXS) and 1~2channel RS232 over fiber transmission. Its merits include complete warning function, high integration, low consumption,stable performance and convenient usage.
