30-Channel Telephone Multiplexer

The TBC-6830U series 30-Channel Telephone Multiplexer is a point-to-point optical transmission equipment developed on the basis of very large-scale integrated circuits. It realizes up to 4 E1 circuits and 1*100M linear Ethernet data channel in a simple form. 30-Channel telephone (FXO, FXS), plus 1~2 channels of RS232 voice and optical transmission equipment. With alarm monitoring and control functions, high integration, low power consumption, stable performance, easy to use.

    This series of optical transceiver to meet the telecommunications operators and private network phone and data access needs. Suitable for power, postal services, banking and China Unicom, mobile telecommunications and other users of the network set up needs, in line with the use of telecommunications operators standards.
