适用范围：1 This Recommendation fixes the rules to be followed in the automatic international Teletex service.2 Teletex is an international service, offered by Administrations, enabling subscribers to exchange correspon-dence on an automatic memory-to-memory basis via telecommunication networks.3 It is intended that the service requirements accommodate a suitable communicating office typewriter as one type of basic Teletex terminal.4 The basic element of the correspondence between people using the service is the page, as the smallest unit of text treated as an entity. No restrictions shall exist as far as the operator procedures for generation of the text or the positioning of text within the printable area on a page are concerned. — 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 — If a graphic symbol that is not in the basic Teletex character repertoire is generated, the service cannot guarantee that it will be represented in a recognizable form at the receiving terminal.5 It is not the intention of the new service to compete with or to duplicate public data services, although the use of Teletex for transmission of data (e.g. to question a data bank) may be a possible by-product.6 Questions of an essentially technical nature concerning the Teletex service are dealt with by other Recommendations.
