摘要
提出了公共信道信令(CCS)网的概念模型,给出如何由业务网的业务增长系数导出信令网的节点间和链路组的业务增长系数,描述了信令业务量预测方法及链路业务量计算方法,并给出了计算实例.
An optical switching system with electric controlling is designed using Bragg acousto optic effect in free space. It composed of acousto optic deflector, dedicated frequency controller, cylindrical lenses(make up a constructure for magnifying angle of visual ), spherical lens and so on, can implement crossbar optical switching of non blocking full permutation. Its main characteristics are low insertion loss, low crosstalk,fast switch speed and simple structure. The simulative experiment of 4×4 crossbar optical switching is made and this result proves that the designed new system is feasible.
