Co-Directional 64K-RS232/422/485 Converter JHA-CE1tD1/R1/Q1

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.

Co-Directional 64K Converter JHA-CE1tV1

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.
