Application of 2M Circuit Switcher for Enhancement of Circuit Reliability
HU Hong-ming · Communications technology · 2010
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.
