摘要
利用现有的用户线路,采用集线器设备,可实现程控交换机(局端)和用户(远端)之间的电话通讯。YH-32型用户集线器设备的研制是近年来十分活跃的用户接入网技术应用的成功一例。它除了具有集线功能外,还有内部交换功能。此设备适合农村等偏远地区通讯,在近一、二十年铜线仍占支配地位的今天,有一定市场潜力和经济效益,是当前解决用户线路紧张状态的一种良好措施。
Using old subscriber lines, between procedure-control-exchange-machi (part end )and user end (remote terminal)can be transmited for the telephone,except concentrating line funtion,it has internaLexchange funtion.The developement uf YH- 32 type subscriber-concentrator equipment is a successful application in current active subscriber-access-network technologyIt is fit for the remote rural area in recent ten to twenty years,copper cable occpy a dominantposition,which has the latent in market and the benefit in econmics,it is a good way to solve theproblem of loops in short supply.
