thumb|right|TTX11 terminal, in this case being relabeled IBM PS/2. Teletex was ITU-T specification F.200 for a text and document communications service that could be provided over telephone lines. It was rapidly superseded by e-mail; however, the name Teletex lives on in several of the X.500 standard attributes used in Lightweight Directory Access Protocol.
==Overview== Teletex was designed as an upgrade to the conventional telex service. The terminal-to-terminal communication service of telex would be turned into an office-to-office document transmission system by teletex. Teletex envisaged direct communication between electronic typewriters, word processors and personal computers. These units had storage for transmitting and receiving messages. The use of such equipment considerably enhanced the character set available for document preparation.
