The G.703 (Co-Directional G.703) interface divides 64Kbps cycle into 4 unit intervals, it uses“0101” represent “0”, “1100” represent “1". By alternating transformation polarity of the adjacent block, binary signals convert three-level signals. In every 8th group destroyed block of alternating polarity, thus to transmit 8KHz timing signal. By the above coding, G.703 co-directional 64Kbps signal could achieve transmitting the timing signal of 64KHz and 8KHz and 64KHz and the data signal of 64Kbit/s in the same direction with a pair balanced line.
64K-V.35/V.24interface converter provides the physical layer conversion between ITU-T co-directional 64K G.703 standard E1 interface and standard V.35/V.24 interface. It provides secure and seamless connectivity for communication between different interface device in the network. The E1 channel timeslots of the transmission device are available for use. Device that needs to be transmitted data only be V35/V24 output. The data interface mode is DCE, which can be docked with the DTE or DCE device.
