7、 7 Summary This Recommendation defines the interworking between different types of access (ISDN and non-ISDN) and the ISDN User Part functions and protocol of Signalling System No. 7. Source ITU-T Recommendation Q.699 was revised by ITU-T Study Group 11 (1997-2000) and was approved under the WTSC Re

8、solution No. 1 procedure on the 12th September 1997. FOREWORD ITU (International Telecommunication Union) is the United Nations Specialized Agency in the field of telecommunications. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of the ITU. The ITU-T is responsible fo

9、r 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 topics for study by the ITU-T St

10、udy Groups 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

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 The ITU draws attention to the possibility that

12、 the practice 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 Recommen

13、dation development 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 informatio

14、n and are therefore strongly urged to consult the TSB patent database. O ITU 1998 All rights reserved.

22、 access (ISDN and non- ISDN) and the ISDN User Part functions and protocol of Signalling System No. 7 i, 2, 3, 4. The non-ISDN access defined in this Recommendation means the analogue line access except the PABX access. The intenvorking between the above signalling protocols occurs in an exchange wi

23、th ISDN local exchange functionality and is specified in the context of a typical call in a pure ISDN or mixed ISDNhon-ISDN environment. 1.2 References The following ITU-T Recommendations and other references contain provisions which, through reference in this text, constitute provisions of this Rec

38、nd redirection number when the national number can be used. The elements of information (parameters, information element and messages) that are of local significance only, i.e. are not mapped onto elements of information in the other signalling system, are not mentioned. Moreover, only the parameter

39、s and indicators being a matter of interworking are described. Hence, no information is given concerning e.g. the satellite indicator, the continuity check indicator, the echo control device indicator, the propagation delay counter parameter. In the same way, information to be sent in case of local

40、fallback or local rejection of Supplementary Services are not relevant to interworking and therefore are not mentioned. ISUP segmentation Some ISUP messages may indicate that they are followed by a Segmentation Message (SGM). The actions described in this Recommendation on receipt of such messages t

41、ake place only after the completion of the segmentation procedure specified in 2.1.12/Q.764 4. When it is said in the text that a parameter is received in an ISUP message, in case of segmentation it could be received in the segmentation message (SGM) as well. ISUP messages which can be segmented and

42、 ISUP parameters which can be conveyed in a segmentation message (SGM) are described in 2.1.12/Q.764 4. DSS 1 segmentation When it is said in the text that a specific DSS 1 message is received, in case of segmentation the content of this message is received in SEGMENT messages. The actions described

43、 in this Recommendation then take place only after the completion of the DSS 1 segmentation procedure specified in Annex WQ.93 1 6. Handling of the cause and location fields When a cause parameter or information element has to be sent by the exchange, only the cause value is given in the text; the l

44、ocation indication is coded according to SI. When a progress indicator information element has to be sent by the exchange, only the progress description is given in the text; the location indication is coded according to 5. The handling of the diagnostic received in a cause parameter or in a cause i

45、nformation element is described in 5.
