G.703 Co-Directional (Co-Dir 64K) to RS232/422/485 Converter, AC or DC power supply

Description

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.

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-RS232/422 / 485 interface converter provides ITU-T co-64K G.703 standard E1 interface and standard RS232 / 422/485 conversion interface between the physical layer. Network to provide secure communications between devices of different interfaces, the seamless connection. Suitable for transmission equipment E1 channel portion slots available, and the equipment needed to transfer data and only RS232 / 422/485 outlet occasions
