摘要
2M电路是目前通信专网中最主要的业务承载形式,因此2M电路的可靠性非常重要,然而,在国内针对2M电路的可靠性研究还很少,针对2M电路的可靠性,很多通信网络采用1+1备份方式,但是,切换动作往往用人工完成,造成通信信息的丢失,2M电路切换器正是为了解决上述问题,它可对2M电路的信号质量进行在线监测,可以实现业务在1+1线路上自动、无损切换,因此2M电路切换器能够提高2M电路的可靠性。
Nowadays,2M circuit is the main service-bearing uppermost form in the private communications network,thus the reliability of 2M circuit plays an important role.However,the research on reliability of 2M circuit is fairly less,and for the reliability of 2M circuit,1＋1 backup networks are widely used,but the switching is manually realized,thus causing the loss of communication information.Now for solving this problem,the 2M circuit switcher is adopted,which could carry out online monitoring of the signal quality in 2M circuit,realize automatic and lossless service switch between 1＋1 circuits.So the 2M circuit switcher could enhance the reliability of 2M circuit.
