IP-PBX的PBX级联软件实现方案

Implementation of Softswith by Integrating PBX with IP-PBX

兼容性是软件化技术发展的方向之一,实现新一代NGN网络设备与传统的PSTN网络设备的相互联是软件换技术兼容性的目标。本文首先对简单的硬件级联方案的分析,发现其不足之处。然后提出了提高IPPBX设备兼容性的三方面需求。最后基于本文所提出的这些要求,探索并设计一种级联端口兼容的,用户编码统一的,接入模式透明的PBX级联模型。

The compatibility is one of the Sotfswitch's developing directions. The interaction between new NGN network and traditional PSTN devices is an important target of Softswith's compatibility. This thesis firstlyanalyzes a hardware design solution and its shortages. Then, set up three basic requirements for improving IPPBX's compatibility. With these three requirements, it practices to carry out a port-compatible, coding-integrated and entrance-apparent model for the integration of PSTN devices.
