     The carrier-grade 4-32-channel telephone optical transmitter is a point-to-point voice optical transmission device developed on the basis of super large-scale integrated circuits. It is a voice optical transmission device that realizes up to four E1 circuits and one 100M wire-speed Ethernet data channel, plus eight voice channels (FXO, FXS or two/four-wire E&M audio), plus four RS232 channels in a simple form. With perfect alarm monitoring function, high integration, low power consumption, stable performance and easy to use.

    This series of voice multiplexer meets the needs of telecom operators and private network users for telephone and data access. Suitable for electric power, postal service, banks and Unicom, mobile telecom and other users of network formation needs, in line with the use of telecommunications operators standards.

    Provide 8-channel voice port: FXO, FXS.
    Each Ethernet interface 10M/100M, full/half duplex fully adaptive, supporting VLAN protocol.
    Each Ethernet port supports support for AUTO-MDIX (crossover and direct line adaptive).
    1 - 8 channel voice access, support for caller ID and reverse polarity billing function.
    Support for mutual release function of each site.
    Voice port supports O and S ports, O port is docked with the program-controlled switch and S port is connected to the user's telephone.
    Voice interface can be optional for two/four-wire E&M audio.
    Fiber interface supports SC/FX interface, and supports single fiber optical interface, providing 1+1 dual optical port backup function.
