ITU-T J.67 FRENCH PDF

The Teletex service provides communication between Teletex equipment¹ which are used for the preparation, editing and printing of correspondence containing text information using a standardized character set (see Recommendation T.61).

The basic element of the correspondence between users is the page which is the smallest unit of text treated as an entity. No restrictions shall exist concerning the operator procedures for generation of the text or the positioning of text within the printable area on a page.

Note 1 - This does not necessarily imply that the characters used to construct a graphic symbol are transmitted in the same sequence as that in which they are keyed.

Note 2 - This does not necessarily imply that the order in which text on a page is transmitted is the same as that in which it was keyed.

Note 3 - An exception to this rule is the application of the processable mode of operation for which the page, as a basic element of correspondence, cannot be used. The processable mode of operation within the Teletex service is defined in Recommendation F.220.

¹ Teletex equipment may be a Teletex terminal or a system.
