ENG: V-COGVE is the converter between G.703 codirectional 64Kbps data channel interface and agreement of V.35 & V.24 used in PDH or SDH equipment with ASIC line designed technology. Codirectional G.703 interface divide 64Kbps cycle into 4 unit space. 0101 means "0", 1100 means "1". By changing the polarities of the adjoining code teams by turns, it will convert binary signal into HDB3 signal. And by destroying the alternation of polarities of code team in every the eighth team, it transmits 8KHz time signals. 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. 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 ignals. If you have any requirement in our products or serves,please tell me without hesitation, we will try our best to help you.And my mail: wujie_23 at shine at
