9、) was approved on 27 January 2006 by ITU-T Study Group 11 (2005-2008) under the WTSA Resolution 1 procedure. ii ITU-T Rec. Q.2630.3 (2003)/Amd.1 (01/2006) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications. The ITU Tel

10、ecommunication 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 Standardization

11、 Assembly (WTSA), 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 WTSA Resolution 1. In some areas of information technolog

12、y which fall within ITU-Ts purview, the necessary standards 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 w

13、ith this Recommendation is voluntary. However, the Recommendation 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

14、language such as “must“ and the negative equivalents 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 t

15、his 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 development process. As of the da

16、te 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 therefore strongly urged to consul

Q.2630.1 15, the abbreviation ALC was used instead of LC. 3) Clause 5.1.2 Revise clause 5.1.2 as follows: 5.1.2 Primitives between AAL type 2 signalling entities and the AAL type 2 served user The A2SU-SAP primitives are used: 1) by the originating s

45、erved user to initiate AAL type 2 connection establishment and by the originating and destination served users to initiate the release of a connection; 2) by the AAL type 2 signalling entities to indicate an incoming connection to the destination served user and notifying either the originating or d

46、estination served user of the release of a connection; 3) by the modification sending served user to originate, and the modification receiving served user to respond to, an AAL type 2 connection resource modification request; and 6 ITU-T Rec. Q.2630.3 (2003)/Amd.1 (01/2006) 4) by the AAL type 2 sign

47、alling entities to indicate a modification of the AAL type 2 connection resource to the modification receiving served user and notify the modification originating served user of the successful or unsuccessful modification. NOTE When sending a primitive between the signalling protocol and its user, t

48、he primitive needs to be associated with a particular AAL type 2 connection instance. The mechanism used for this binding is considered to be an implementation detail and therefore is outside the scope of this Recommendation. The services are provided through the transfer of primitives which are sum

49、marized in Table 5-1, and are defined after the table. The AAL type 2 served user passes information in parameters in the primitives. Some of those parameters are mandatory and some are optional; the appropriate usage of the parameters is described in clause 8.
