Source ITU-T Recommendation T.35 was revised by ITU-T Study Group 8 (1997-2000) and was approved under the WTSC Resolution No. 1 procedure on 10 Febru
5、ary 2000. Recommendation T.35 (02/2000) 1 FOREWORD ITU (International Telecommunication Union) is the United Nations Specialized Agency in the field of telecommuni- cations. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of the ITU. The ITU-T is responsible for studyin
6、g technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Conference (WTSC), which meets every four years, establishes the topics for study by the ITU-T Study Group
7、s which, in their turn, produce Recommendations on these topics. The approval of Recommendations by the Members of the ITU-T is covered by the procedure laid down in WTSC Resolution No. 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared
8、on a collaborative basis with IS0 and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. INTELLECTUAL PROPERTY RIGHTS The ITU draws attention to the possibility that the prac
9、tice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. The 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 de
10、velopment process. As of the date of approval of this Recommendation, the ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementors are cautioned that this may not represent the latest information and are
11、 therefore strongly urged to consult the TSB patent database. O ITU 2000 All rights reserved.

14、DARD FACILITIES (revised 2000) 1 Introduction The binary coded control procedures provide for the inclusion of non-standard facilities in addition to the standard facilities given in the appropriate T series of Recommendations and require a unique code to be allocated to each provider who includes s
15、uch non-standard facilities. Other ITU-T Recommendations may also use this method to identify the use of non-standard facilities in their procedures. This Recommendation defines the procedure for the allocation of ITU-T defined code for non-standard facilities. 2 Structure of the ITU-T defined code
16、The ITU-T defiied code consists of three parts which are: country code, terminal provider code and terminal provider oriented code in the case of terminal specific non-standard facilities. The country code identifies the country, the terminal provider code identifies the provider and the terminal pr
17、ovider oriented code is defiied by each provider. 3 Procedure for the allocation of ITU-T defined codes 3.1 Country code The Director of TSB has the responsibility for the allocation and management of the country codes. The country or area codes should be as in Annexes A and B. The code 11 11 11 11
18、in Annex A is an escape code used to indicate that the next octet contains a code given in Annex B. Whenever the code 11 11 11 11 is used in the first octet, the country or area code will be found in Annex B. NOTE - The list of country or area codes in Annex A reflects the status as it existed in th
19、e 1990 version. Codes once issued may have been imbedded in terminal equipment and therefore should not be changed or reassigned even if the country or area is no longer a valid destination. The Member countries of the International Telecommunication Union not mentioned in this list who wish to obta
20、in a country or area code should ask the Director of TSB for the assignment of an available country code. In their request, they may indicate a specific code if it is available. 3.2 Terminal provider code An Administration, or a national body designated by an Administration, has the responsibility f
21、or the allocation and management of the terminal provider code. When an Administration designates a national body, its address and name should be sent to the Director of TSB (Telecommunication Standardization Bureau). The procedure for the allocation of the terminal provider code should be defiied b
22、y each Administration or designated national body. NOTE - Terminal provider codes may consist of one or more octets. Recommendation T.35 (02/2000) 1 3.3 Terminal provider oriented code Terminal providers that have been allocated a provider code by an Administration, or a national body designated by
23、an Administration, have the responsibility for the allocation and management of each terminal provider oriented code. NOTE - When the extended country code is used, it requires a code space of two octets. The allocation of additional code space in addition to the country code for the terminal provid
24、er code and the terminal provider oriented codes is a national matter. When Recommendations such as the H- and T-series Recommandations use the area or country codes defined by Recommendation T.35, care should be taken not to exceed the total allocated code space. 4 Disclosure of ITU-T defined codes
