Abbreviation of telegraph-exchange. A recording communication method that combines automatic telephone switching technology with telegraph transmission and printing telegraph technology. Also called subscriber telegraph. Just like a telephone, a telex number is used to connect to the other subscriber, and communication can be made using a printer or display terminal, so it can be said to be a communication method that combines the characteristics of telephone service and telegraph service. In Japan, the Nippon Telegraph and Telephone Public Corporation (now NTT) started a service mainly for domestic connections in 1956, while the International Telegraph and Telephone Company (now KDDI) started a service for international connections only. The number of subscribers has steadily increased, peaking at about 76,000 in 1976. Since then, the number has been on a downward trend due to the expansion of facsimile communication and the spread of e-mail over the Internet. In September 2002, NTT Communications stopped accepting new subscribers, assuming that the service would be discontinued.

telegraph-exchangeの略。電話の自動交換技術と、電信の伝送および印刷電信技術とを組み合わせた記録通信方式。加入電信ともいう。電話と同じようにテレックス番号で相手加入者に接続し、プリンターまたはディスプレー式端末等を使ってお互いに通信できるので、電話サービスと電信サービスの特徴をあわせもった通信といえる。 日本では1956年(昭和31)から当時の日本電信電話公社(現NTT)が国内接続を主体としたサービスを、国際電信電話会社(現KDDI)が国際接続のみのサービスを開始した。加入者は着実に増加してきたが、1976年の約7万6000加入がピークであった。それ以後、ファクシミリ通信の拡大、インターネットの電子メールの普及などにより減少傾向にある。NTTコミュニケーションズは2002年(平成14)9月、サービス廃止を前提とし、新規加入受付を停止した。 [坪井 了] 出典 小学館 日本大百科全書(ニッポニカ)日本大百科全書(ニッポニカ)について 情報 | 凡例 |
