16、830-en. ii Rec. ITU-T E.161 (2001)/Amd.1 (06/2014) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a pe

17、rmanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Assembly (WTSA), which meets every four years, estab

18、lishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of information technology which fall within ITU-Ts purview, the necessary sta

19、ndards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. Compliance with this Recommendation is voluntary. However, the Re

20、commendation may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words “shall“ or some other obligatory language such as “must“ and the negative equivalent

21、s are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTS ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed

22、 Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process. As of the date of approval of this Recommendation, ITU had rece

23、ived notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database at http:/www.itu.int/ITU-T/ip

ITU-T E.161 (2001)/Amd.1 (06/2014) 1 Recommendation ITU-T E.161 Arrangement of digits, letters and symbols on telephones and other devices that

25、can be used for gaining access to a telephone network Amendment 1 New Annex A: Arrangement of digits, Korean Character set and symbols Add the following annex to the Recommendation: Annex A Arrangement of digits, Korean Character set and symbols (This annex forms an integral part of this Recommendat

26、ion.) The basic configuration of a telephone keypad consists of 12 keys: 10 numeric keys (1, 2, 3, 4, 5, 6, 7, 8, 9, 0) used in dialling a phone number, and two control keys that are pressed to invoke specific functions. To enter Korean consonants and vowels, three components of vowel strokes (, , )

27、 are arranged on three keys and used in 21 vowel codes combining simple vowels (, , , , , , , , , ) and diphthongs (, , , , , , , , , , ), depending on the sequence of key input. Simple consonants (, , , , , , , , , , , , , ) are assigned to seven keys at two consonants per key. Each of the first se

28、ven consonants entered as a consonant key is pressed once, each of the second seven consonants entered as consonant key is pressed twice and each of the five double letter codes entered as consonant key is pressed three times. Korean consonants on the keypad described herein are arranged to be enter

29、ed when the same key is pressed repeatedly or in combination with a control key. The key code entered repeatedly is recognized as a consonant or a vowel unit in accordance with the Korean consonant and vowel combination rules. In case the first consonant becomes the final consonant of a syllable and

30、 the second consonant becomes the first consonant of the following syllable when both consonants are assigned to the same key, a separator is entered between the two consonants to distinguish them.
