在“调整、改革、整顿、提高”方针的指引下,在我所已研制试用明线高12路载波电话设备的基础上,为了进一步挖掘架空明线的潜力,节省线路投资费用和有色金属材料,在电缆、光缆通信大量运用之前,明线超24路载波电话设备是充分利用现有线路设备,迅速增加通信容量的一个有效办法.本文着重对明线超24路载波设备制式设计中所涉及到的一些主要问题进行了分析、讨论和工程计算,确定了实现这一载波系统的方案及部件的技术要求.由于缺乏实际设计经验,难免有考虑不周之处,甚至错误的地方,欢迎同志们批评指正.
Under the guidance of the guideline of “adjustment, reform, rectification and improvement”, on the basis of the trial-use 12-channel high-speed carrier telephone equipment that I have developed, in order to further tap the potential of overhead line and save on line investment costs and non-ferrous metal materials, Prior to the extensive use of cable and optical cable communications, the Ming Line Super-24 Carrier Telephone Equipment is an effective way to make full use of the existing line equipment to rapidly increase the communication capacity.This paper focuses on some of the major The problems have been analyzed, discussed and calculated, and the technical requirements for implementing the scheme and components of this carrier system have been determined. Due to the lack of practical design experience, it is inevitable that there are inevitable places for consideration or even errors. Welcome comrades to criticize and correct them.
