                16FXO/FXS PCM Voice Multiplexer Over Optical Fiber

                This model is the point-to-point optical transport equipment based on self copyright IC. It is single board structure and provided with complete alarming function. It offers 1~4 10/100M Ethernet channels and 1~16 voice (FXS/FXO) channels and 1~4 serial data channels for option. It can realize SNMP management on stand-alone device via built-in SNMP module. The outer design use the standard 19 inches rack, so the volume is small, weight is light and operation is convenient and credit.
