ITU-T Recommendation X.34 Access to packet switched data transmission services via B-ISDN CORRIGENDUM 1 Source Corrigendum 1 to ITU-T Recommendation X.34 was prepared by ITU-T Study G

8、roup7 (1 997-2000) and approved under the WTSC Resolution 1 procedure on 3 1 March 2000. FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ

9、 of ITLJ. 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 Conference (WTSC), which meets every four years, establishes the

10、 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 WTSC Resolution 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are

11、 prepared 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 ITU draws attention to the possibility that th

12、e practice or implementation of this Recommendation may involve the use of a claimed 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

13、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 required to implement this Recommendation. However, implementors are cautioned that this may not represent the latest information and are t

14、herefore strongly urged to consult the TSB patent database. o nu 2001 All rights reserved.

15、on X.34 Access to packet switched data transmission services via B-ISDN CORRIGENDUM 1 1) Clause 2 References a) Rationale: ITU-T 1.362 was deleted in Study Group 13. b) Replace the reference to ITU-T 1.363, as follows: ITU-T Recommendation 1.363.5 (1 996) - B-ISDN ATM adaptation layer AAL speczjkati

16、on Type 5 AAL. Rationale: ITU-T 1.363 was separated for each AAL protocol in Study Group 13. Among them, Delete reference .i to ITU-T Recommendation 1.362. Type 5 AAL is the only one relevant to ITU-T X.78. 2) Replace bullet c): This Recommendation defines the procedures at the user-network interfac

17、e of a B-ISDN to access packet switched data transmission services provided by a PSPDN or an ISDN in alignment with Recommendations 1.432,1.361,1.362,1.363,Q.2110 and Q.2130. with: This Recommendation defines the procedures at the user-network interface of a B-ISDN to access packet switched data tra

18、nsmission services provided by a PSPDN or an ISDN in alignment with ITU-T 1.432,1.361,1.363.5,Q.2110 and Q.2130. Rationale: See clause 1. 3) Clause 6 Reference configuration Replace: NOTE 1 -ATM capabilities are in accordance with Recommendations 1.361,1.362,1.363,1.432, 4.2110 and 4.2130 for TEs/TA

19、s attached to a B-ISDN. with: NOTE 1 -ATM capabilities are in accordance with ITU-T 1.361, 1.363.5, 1.432, 4.21 10 and 4.2130 for TEs/TAs attached to a B-ISDN. Rationale: ITU-T 1.362 was deleted in Study Group 13. 4) Table in Annex A a) Rationale: No existing Recommendation defines this cause. b) Ra

20、tionale: Alignment with ITU-T Q.2610. c) Rationale: In this table, 4.2931 cause, Code 93 appears twice with different explanations. 6.434.293 1 defines Code 73 as “Unsupported combination of traffic parameters“, and Code 93 as “AAL parameters cannot be supported“. This corrects a typographical error

21、. Clause 5 General service aspects Delete the row 4.2931 cause, Code 10. In the row Q.2931 cause, Code 51, change Code 51 to Code 37. In the row Q.2931 cause, Code 93, change Code 93 to Code 73.
