10、ITU-T Rec. E.123 (2001)/Amd.1 (05/2008) i ITU-T Recommendation E.123 Notation for national and international telephone numbers, e-mail addresses and Web addresses Amendment 1 Summary Amendment 1 to ITU-T Recommendation E.123 applies specifically to the printing of national and international telephon
11、e numbers, electronic mail addresses and Web addresses on letterheads, business cards, bills, etc. Regard has been given to the printing of existing telephone directories. The standard notation for printing telephone numbers, e-mail addresses and Web addresses helps to reduce difficulties and errors
12、, since this address information must be entered exactly to be effective. Source Amendment 1 to ITU-T Recommendation E.123 (2001) was approved on 15 May 2008 by ITU-T Study Group 2 (2005-2008) under the WTSA Resolution 1 procedure. ii ITU-T Rec. E.123 (2001)/Amd.1 (05/2008) FOREWORD The Internationa
13、l 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 permanent organ of ITU. ITU-T is responsible for studying technical, operating
14、 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, establishes the topics for study by the ITU-T study groups which, in turn, produc
15、e 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 standards are prepared on a collaborative basis with ISO and IEC. NOTE In this
16、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 Recommendation may contain certain mandatory provisions (to ensure e.g. intero
17、perability 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 equivalents are used to express requirements. The use of such words does not suggest tha
18、t 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 Intellectual Property Right. ITU takes no position concerning the evidence, v
19、alidity 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 not received notice of intellectual property, protected by patents, which may be r
20、equired 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/ipr/.

22、Emergency contact number notation In order to facilitate calling of family members or other contact persons in case of emergency, owners of a mobile handset can indicate such contact numbers by the following notation, to be entered into the “name“ field of the handsets directory. The “number“ field
23、would contain the actual contact number. Format of the name: 0nX, where n is a digit from 1 through 9 and X is any meaningful descriptive character string (for example, “spouse“, or “home number“).
