大规模电话线路扩容器的研究

Study on Large Scale Telephone Line Expanding Devices

本文利用多信道共用技术研制了大规模电话线路扩容器。实现16～32个电话用户共用4～6对电话线路,且各用户的话机具有独立的电话号码,从而提高电话线路利用率,解决安装电话时线路紧张的问题。

The large-scale telephone line expanding dev ic es,which are based on the technology of the multi-channels share are discussed i n the paper.The devices makes that16to32telephone users share with4to6pairs of t elephone line come true,and also each users have his own only telephone number,a ccordingly it the rate of the telephone line using is enhanced and the problem o f fixing telephone with line scarcity is solved.The hardware and software of the devices are designed.The anti-jamming measure is adopted,and the call loss of t he users is also analysed.
