Telephone communication is the most widely employed ways of communication in the world. telephone communication is becoming more and more important as the national economic reform deepens. dynamic channel borrowing assignment mode is an effective method in communication channel expansion. although it has been put into practical use in satellite communication and mobile communication, no one has attempted to apply it to telephone line expansion. in this paper the author expands the telephone line via dynamic channel borrowing assignment mode, ascertains the expansion scheme, designs the circuit of hardware in telephone line expansion device, draws up software programme, analyses the call lose after using the expansion device theoretically and then experiments to verify it. eight subscribers can share one or two telephone lines with the help of the telephone line expansion device with each phone a sole number. this makes it possible for subscribers to use any free telephone line. thus increasing the number of subscriber and utilization ration of telephone line. in addition. this project makes it possible for expansion subscribers to communicate directly while not to make use of outer line. which further decreased the system call lose
多通道共用是通信通道擴容的一種有效的方法，已在衛星通信、移動通信中得到應用，但尚未應用到電話線路擴容中。本文利用多通道共用原理對電話線路進行擴容，確定了多通道共用方式電話線路擴容的設計研究方案，研究設計了電話線路擴容器的硬體電路，編制了電話線路擴容器的軟體，並對使用電話線路擴容器后的呼損進行了理論分析及試驗研究。本文研究設計的多通道共用方式電話線路擴容器可以使8個用戶共用1 2對電話線路，每部用戶話機都具有獨立的電話號碼，可以利用任一空閑的電話線路，故能夠增加電話用戶，提高電話線路的利用率。 -
