The present document specifies the minimum repertoire and assignment of graphic (letter@ digit and special) characters to standard 12-key telephone keypads on ICT devices with telephony functionality. The present document applies to public or private@ fixed or mobile network terminals@ without an alphanumeric keyboard but providing a 12-key keypad in hardware form (e.g. as push button keys) or software form (e.g. as soft keys on a visual display). The ES also applies to network-based services accessed through such terminal devices. The present document complements ETS 300 640 [1] by additionally including European language-specific letters (Latin@ Greek and Cyrillic scripts) and other common characters (e.g. the Euro sign and punctuation marks). The present document specifies solutions for both language-independent and language-specific keypad assignments@ mapped to the 12-key telephone keypad. The document also provides common and language-specific information on character repertoires and ordering. The present document is fully applicable to the languages of the European Union (EU) member states as of 2004 (also covering the official languages of the European Union [9]@ [12]@ [19]) and those of near-term enlargement candidate countries and@ additionally@ to the official languages of the EFTA countries and Russian. In anticipation of future expansions@ the language-independent repertoires and keypad assignments specified in the present document also include letters needed in some of the remaining European official languages. Future revisions of the present document may include the letters of other languages and other characters. The names of the languages used in the present document are aligned with those used in ISO/IEC standards for language codes.
