| Abstract: | 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. |
