Co-Directional 64K Converter JHA-CE1tV1 Co-Directional 64K Converter JHA-CE1tV1

Co-Directional 64K Converter JHA-CE1tV1

Co-Directional 64K-V.35 Converter JHA-CE1tV1 Overview 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.24 interface converter provides ITU-T co-64K G.703 standard E1 interface and standard V.35 conversion interface between the physical layer / V.24. Network to provide secure communications between devices of different interfaces, the seamless connection. Equipment E1 channel section applies to transmission equipment slots available, and the need to transfer data to and only V35 / V24 export of the occasion, the data interface mode is DCE, with DTE or DCE device docking.
