摘要 本文基于蓝牙标准及其应用模型 ,阐述了“三合一电话”的概念 ,给出了所研制的两种版本的蓝牙 PSTN网关和语音终端的设计及实现情况。文章首先简述了所研制的 PC版本协议栈的特点及其创新 ,包括虚拟操作系统 ( VOS)的设计和实现以及屏蔽字节序、字节对齐等措施 ,接着给出了该版本设备的研制情况 ;然后对嵌入式 PSTN网关和语音终端的设计和实现做了阐述 ,着重讨论了嵌入式软件以及支持多个终端的 PSTN网关的实现 ;最后给出 Based on the Bluetooth specification and profiles, this paper discusses the concept of 3-in-1 phone and the design and realization of two versions of Bluetooth PSTN gateway and audio terminal developed by the authors. First, this paper illustrates the characteristic and innovation of PC version of Bluetooth protocol stack developed by us, which includes the design and realization of Virtual Operating System(VOS) and such methods as bytes sequence and bytes alignment shield, and discusses the development of equipments. Then, the design and realization of embedded PSTN gateway and audio terminal are discussed, the realization of embedded software and PSTN gateway that supports multi-terminals are emphasized. Finally, the application prospects of PSTN gateway and audio terminal are introduced.
