Co directional G.703/64K to V.35, V.24 or X.21 Converter COGVE
Overview:
With more and more application of digital channel transmitting data in the speed of 2M, G.703 defined physical and electrical characteristics of classified digital interfaces. Using analog communicating net transmitting data signals, the data rate of a line is lower than 19.2Kbps, while it is up to 64Kbps in digital communicating net to transmitting data signals with low wrong code rate and good communicating quality. To those data communicating equipments with functions and characteristics of V series of suggested interfaces to transmit data by digital channels, interface and speed rate converters are needed between data and PCM equipments.
Features:
1. V-COGVE is the converter between G.703 co directional 64Kbps data channel interface and agreement of V.35 & V.24 used in PDH or SDH equipment.
2. By dealing with codes, it transmit 64KHz time signals, 8KHz time signals and 64Kbit/s digital signals in the same direction with a pair of balance lines. To full duplex communication, interface only need two pairs (4 lines) of balance lines. But if it is not inverted or middle, the interface need a pair of balance lines specially to transmit clock time signals.
3. It was based on ASIC line designed technology
4. Codirectional G.703 interface divide 64Kbps cycle into 4 unit space.
5. By changing the polarities of the adjoining code teams by turns, it will convert binary signal into HDB3 signal.
6. By destroying the alternation of polarities of code team in every the eighth team, it transmits 8KHz time signals
7. By dealing with these codes, G.703 codirectional 64 Kbps signals can transmit 64 KHz time signals, 8 KHz time signals and 64Kbit/s digital signals in the same direction with a pair of balance lines
