clocked violation HI(CVH)

A symbol which deliberately violates Manchester encoding rules, used as part of the collision presence signal. A CVH is encoded as a transition from LO to HI at the beginning of the bit-cell, HI for the entire bit-cell, and atransition from HI to LO at the end of the bit-cell.; 有意違反曼徹斯特編碼規則的一種符號,用作沖突存在信號的一部分。在該比特碼元開始時,CVH編碼為從LO到HI的轉移,整個比特碼元的HI,在該比特碼元結束時編碼為從HI到LO的轉移。
