基于TCP/IP交换机的集中操作维护系统的实现

介绍了Windows“钩子”的概念和原理，分析了目前基于TCP／IP程控交换机的一些现状，提出了实现基于TCP/IP交换机集中操作维护系统的解决方案。沿用程控交换机原有操作维护终端，在操作终端界面上注入“钩子”，增设中间操作控制层网关服务器，采用三层的体系结构，满足了交换机集中操作维护系统的需求。方案已经在广东电信交换机集中操作维护系统上得到了应用，实践证明所述解决方案是可行的。

Realization of PBX centralized management based on TCP/IP

At first, the concept and principle of hook are introduced, The aspects of the PBX centralized management are reviewed based on TCP and IP. And a solution is put forward which satisfies the need of the PBX centralized management system. This solution inherits the terminal interface of PBX, makes use of technique named hook, adds a control medium named gateway, and forms a system with three-layers. This solution is adopted by the PBX centralized management system in Guangdong Telecom. It is proved that the solution is practical and rational.
