这篇文章叙述LM伊立克生所设计的在单管小同轴上,实现双向传输120个话路的高频线路设备.目前的金属线载波系统是小容量的,它主要由明线和对称电缆上的12路、24路及60路系统组成的.由于这些高频线路电路容量有限及其每条话路的线路成本很高,所以它们在作为发展一种新网络或提供新电路的选择上,不再有多大吸引力了.两地之间的话务量可以料到在不久的将来相对来说是有限的,若要建立300～960路或更
This article describes LM Ellicott’s design of a high-frequency line device that enables 120-way transmission in both directions on a single small coaxial line. The current metal-line carrier system is small-capacity and consists mainly of bright lines and symmetric Cables consisting of 12-way, 24-way and 60-way systems Because of the limited capacity of these high-frequency line circuits and the high line costs per session, they are being chosen as a way to develop a new network or to provide new circuits , There is no longer much attraction.The traffic between the two places can be expected to be relatively limited in the near future, to establish 300 ~ 960 or more
