随着社会的发展,电话已成为工作与生活中不可缺少的通讯工具。然而,自己打电话却让别人交费,已成为现代社会中一种新型的偷窃行为。许多人有时会收到莫明其妙的电话费单子。而根本不知道打电话的是谁,于是就到电话局去询问。这样不仅使电话用户的切身利益蒙受损失,也给电话局增加了许多麻烦。在某种程度上来说,这是传统有线电话通讯系统潜在的一种缺陷。随着电话业务的日益普及和电话用户的巨增,这一潜在的缺陷逐渐地暴露出来,已成为亟待解决的突出问题。为了保护电话用户的切身利益,增强电话局对电话线路的管理能力,提高市话的服务水平,笔者根据现已广泛使用的各种有线电话程控交换机的技术现状及有线电话通讯技术的实际情况,在此提出一种解决电话线路易被盗用的方案,同时附带介绍一种与之相关的新型专利电话机,旨在为电话局在现有程控交换机上开设一种“电话密码锁”的服务业务,从根本上杜绝用户电话线路被盗用现象的发生。 With the development of society, telephone has become an indispensable communication tool in work and life. However, making calls on their own while paying others has become a new type of theft in modern society. Many people sometimes get a baffling phone bill. And do not know who is calling, so went to the telephone office to ask. This not only caused the loss of the vital interests of the telephone users, but also added a lot of trouble to the telephone office. To some extent, this is a potential drawback of the traditional wired telephone communication system. With the increasing popularity of telephone services and the huge increase of telephone subscribers, this potential defect has gradually been exposed and has become a prominent problem to be solved urgently. In order to protect the vital interests of the telephone users and enhance the telephone line management ability of the telephone bureau and to improve the service level of the local telephone service, according to the actuality of the technical status of all kinds of wired telephone program-controlled switches and the actual situation of the wired telephone communication technology now widely used, This proposed a solution to the problem of theft of telephone lines easily. At the same time, a new type of patent telephone was introduced with the aim of providing a “telephone code lock” service service for the telephone exchange on the existing program- Fundamentally put an end to the occurrence of theft of telephone lines.
