Abstract

PURPOSE:To secure the same answer signal type for the data center through selection of the signal type of the answer information by memorizing the function type of the data telephone in the subscriber information memory, and thus to realize the nationwide transmission of the data via the telephone network. CONSTITUTION:In case data telephone DT possessing the display means such as lamp part L, display part D, printer part P and others is connected to data center CNT via exchange SW, memory M momorizing the function type DT is provided to SW in correspondence to DT along with output device TONE and FSOS in correspondence to each display means of DT respectively. Thus, the output device of the receivable signal type is selected at DT in reference of the memory contents of M when the information is transmitted to DT from CNT. And the selected output device transmits the information to DT from CNT.
