近年来陆续从国外引进了一些程控交换机,这给我们带来一系列新问题。诸如程控交换机的选型,机房内的布局,对机房的环境要求,程控交换机的供电系统、接地系统,程控交换机的维护管理,等等。本文以美国联合技术电讯公司生产的DBX-1200型用户程控交换机为例,并根据国外资料及作者参加引进、维护程控交换机的实际经验,对上述问题作一些介绍。最后,还对程控交换机维护人员的培训提出一些看法。
In recent years, one after another from the introduction of a number of program-controlled switches from abroad, which brought us a series of new issues. Such as program-controlled switchboard selection, the layout of the engine room, the engine room environment requirements, program-controlled switchboard power supply system, grounding system, program-controlled switchboard maintenance management, and so on. This article takes DBX-1200 PABX produced by United Technologies Corporation as an example. Based on the foreign materials and author’s participation in the introduction and maintenance of program-controlled switches, we introduce some of the above problems. Finally, we also put forward some thoughts on the training of program-controlled switch maintenance personnel.
