ITU-T Recommendation X.78 Internorking procedures between networks providing frame relay data transmission services via B-ISDN CORRIGENDUM
8、1 Source Corrigendum 1 to ITU-T Recommendation X.78 was prepared by ITU-T Study Group7 (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 telecommunicatio
9、ns. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent 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
10、Standardization Conference (WTSC), which meets every four years, establishes 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 WTSC Resolution 1. In some areas of info
11、rmation technology which fall within ITU-Ts purview, the necessary standards are 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 age
12、ncy. 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, validity or applicability of claimed Intellectual Property
13、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 required to implement this Recommendation. However, impleme
14、ntors are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database. o ITU 2001 All rights reserved.

ITU-T Recommendation X.78 Interworking procedures between networks providing frame relay data transmission services via B-ISDN CORRIGENDUM 1 1) Clause 2 a) Delete reference 5 to ITU-T Recommendation I. 362. Rationale: ITU-T 1.362 was de
16、leted in Study Group 13. b) Replace item 6, ITU-T Recommendation I. 363, as follows: ITU-T Recommendation 1.363.5 (1 996), B-ISDN ATM adaptation layer AAL speczjkation - Type 5 AAL. Rationale: ITU-T 1.363 was separated for each AAL protocol in Study Group 13. Among them, 2) Subclause 11.1 Replace th
17、e first sentence, Type 5 of the AAL functions applies (see Recommendation 1.362 and 1.363). Type 5 AAL is the only one relevant to ITU-T X.78. with : Type 5 of the AAL functions applies (see ITU-T 1.363.5). Rationale: See clause 1. 3) Subclause 11.2 Replace the first sentence, , Type 5 of the AAL fu
18、nctions applies (see Recommendation 1.362 and 1.363). with: Type 5 of the AAL functions applies (see ITU-T 1.363.5). Rationale: See clause 1.
