7、commendations was agreed on 28 July 2006 by ITU-T Study Group 11 (2005-2008). ii Q series Supplement 37 (07/2006) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications. The ITU Telecommunication Standardization Sector (IT

8、U-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 Assembly (WTSA), which meets every four

9、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 technology which fall within ITU-Ts purview, the n

10、ecessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this publication, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. Compliance with this publication is voluntary. However,

11、the publication may contain certain mandatory provisions (to ensure e.g. interoperability or applicability) and compliance with the publication 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

12、are used to express requirements. The use of such words does not suggest that compliance with the publication is required of any party. INTELLECTUAL PROPERTY RIGHTS ITU draws attention to the possibility that the practice or implementation of this publication may involve the use of a claimed Intelle

17、 element 12 Q series Supplement 37 (07/2006) 1 Supplement 37 to ITU-T Q-series Recommendations DSS1 and DSS2 messages and information element identifiers 1 Introduction DSS1 and DSS2 message and information element identifiers are defined in several Recommendations of the Q-series 1 to 24. Frame Rel

18、ay DTE-DCE and NNI signalling defined in ITU-T Recs X.36 and X.76 25 and 26 use the same protocol discriminator as DSS1 and therefore the same identifier spaces. In addition, several message and information element identifiers have been allocated to the MFA Forum from DSS2 identifier spaces and some

19、 information element code points have been reserved to the MFA Forum. The purpose of this supplement is to record in one place DSS1 and DSS2 message and information element identifiers defined in the following Recommendations: DSS1 Recommendations: ITU-T Recs Q.931, Q.932 and Q.952 1, 2 and 4. DSS2

20、Recommendations: ITU-T Recs Q.2931 and other Recommendations 5 to 24. Frame relay Recommendations: ITU-T Recs Q.933, X.36 and X.76 3, 25 and 26. In addition, this supplement records DSS2 message and information element identifiers and DSS2 information element code points reserved to the MFA Forum. T

21、his supplement is structured as follows: clause 1.1 lists ITU-T Recommendations referred to in this supplement. Clause 1.2 explains the convention used to create the two tables of DSS1 and DSS2 messages and information elements. Clauses 2 and 3 list DSS1 and DSS2 messages and information elements re

22、spectively. Finally, clause 4 records DSS2 information element code points reserved to the MFA Forum. 1.1 References 1 ITU-T Recommendation Q.931 (1998), ISDN user-network interface layer 3 specification for basic call control. 2 ITU-T Recommendation Q.932 (1998), Digital subscriber signalling syste
