The Optimum Computing for Circuit Numbers of Trunk Circuit Network in a Local Telephone Network

讨论了中继电路的组织及中继电路网的电路数的优化计算方法，并对一个市内电话网的实例进行了优化计算。本计算理论和方法适用于铜芯电缆、ＰＣＭ 电缆及光缆传输媒介的中继网的优化计算，具有一定实用价值。

The organization of trunk circuit and the optimum computing method of the circuit numbers in trunk circuit network are presented, and a practical optimum computing example is carried out for a local telephone network. This compute theory and method can be applied to the optimum computing for trunk network using copper cables,PCM cabels and optical fiber cables as trnsmission media,and is practicable.
