Applied-Information Technology with Design and Development of Bluetooth PSTN Gateway and Audio Terminal
Abstract:
Based on the Bluetooth specification and profiles, this paper discussed 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 characteristics 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.
