长途电话交换网网管系统的设计与实现

针对长途电话交换网交换机机型多、网管接口不统一的状况，采用两种不同的方法管理交换机，并建立了长途网网管模型。基于该网管模型，着重研究了网管系统中关键部分综合集中维护系统的软件实现。该软件采用模块化设计，定义了共用模块和专用模块之间的接口。实现了共用模块和若干专用模块。软件可扩展，方便引入新的类型交换机。

Design and Realization of the Management System for Toll Telephone Network

In oder to supply a high level service, the toll telephone network requires a modern network management. But for many types of switches and many kinds of network management interfaces, it is difficult to work out that. Based on the investigation of switches types, it is suggested to manage all the switches in two ways. And also a model of toll telephone network management is made. Based on the model, the software of integrated centralized operation system has been designed in modularization. The interface between the public modular and the private modulars has been defined, and the public modular and server private modulars have been developed. The software is expandable, so a new private modular can be quickly developed.
