Abstract
Aspects of data communications in Japan are broadly summarized in this paper. First, various networks for data communication are described and some examples of data communication services using these networks are mentioned. Next, some topics in data communication technology are outlined. Topics include two large-scale computer projects and R&D on pattern recognition techniques in the data-processing field, standard modems now in use and new modems for PCM transmission and other uses in the data transmission field, optical character readers (OCR) and an audio-response unit, as well as various printers in the data terminal equipment field.
