Telephone systems were introduced in Taiwan in the early twentieth century. Automatic exchange systems were yet to mature then, and equipment of telephone exchanges was upgraded at different speeds. Therefore, after a long period of time, a kind of new job was created: the operator. This study attempts to, in terms of the development trend of the gender of the operators, explore how the telephone system, following telegram, found its way into Taiwan's information network (progress and division of labor) in the initial construction of a twentieth-century information society. Quality hinged on the artificial interface-the service of the operator. Moreover, by investigating the flow of information 24 hours a day, the present work seeks to sketch the operator's life and adaption to the dual pressure, internal control and customers. Finally, this study tries to get an understanding of how the occupation was impacted, responded and declined after the advent of the automatic exchange system in the late 1920's, in order to serve as a reference for qualitative research in observing how the Taiwanese information society was constructed.
