摘要
鸳鸯线通常存在于2 Mbit/s传输系统里,具有隐蔽性较强的特点,尤其是与其它故障并发时,极大地增加了故障的排除和处置难度,必须要及时处理好。文章以典型视频会议传输系统为对象,阐述了视频会议传输系统中鸳鸯线的形成机理;接着深入分析了视频会议传输系统中7类鸳鸯线的特点规律,给出了具体的判定方法及其处置方法;最后总结了判定和处置鸳鸯线的总体思路和流程。所提方法是笔者在工作实践中的经验总结,对相关技术人员在处理鸳鸯线故障时具有一定的参考价值。
Cross-connection usually exists in 2 Mbit/s transmission system,which has the characteristics of strong concealment.Especially when it is concurrent with other faults,it greatly increases the difficulty of troubleshooting and handling,so it must be eliminated and handled in time.Therefore,it takes the typical video conference transmission system as the object in this paper,and the formation mechanism of cross-connection in video conference transmission system was described;Then,the characteristics of seven kinds of c ross-connection in video conference transmission system were analyzed,and the specific judgment and disposal method were given;Finally,the general idea and process of judging and disposing cross-connection were summarized.The proposed method in this paper is the experience summary of the author in the work practice,and has a certain reference value for the relevant technical personnel.
