H.248.34 (01/2005) i ITU-T Recommendation H.248.34 Gateway control protocol: Stimulus analogue line package Summary This Recommendation describes
7、a Stimulus Analogue Line package that defines new H.248 events, signals and parameters derived from the V5 PSTN protocol defined in ITU-T Rec. G.964. To assist both vendors and operators in migrating V5 Local Exchange and access network nodes to a Next Generation Network Media Gateway and Media Gate
8、way Controller architecture, the package provides guidelines for mapping the V5 PSTN Protocol to the “Stimulus Analogue line“ package, other H.248 packages and the H.248.1 protocol. Source ITU-T Recommendation H.248.34 was approved on 8 January 2005 by ITU-T Study Group 16 (2005-2008) under the ITU-
9、T Recommendation A.8 procedure. ii ITU-T Rec. H.248.34 (01/2005) 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 of ITU. ITU-T is respon
10、sible 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 years, establishes the topics for study by the IT
11、U-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 necessary standards are prepared on a collaborativ
12、e 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 with this Recommendation is voluntary. However, the Recommendation may contain certain mand
13、atory 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 language such as “must“ and the negative equivalents are used to express requirements. The
14、 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 this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes
15、 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 date of approval of this Recommendation, ITU had not received notice of intellectual propert
16、y, 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 consult the TSB patent database. ITU 2005 All rights reserved.

19、ents that are exchanged between a MG and a MGC for controlling analogue POTS lines which can, for example, be used to host telephones, analogue PBXs and turn-key systems. The signals and events defined in the package are stimulus in nature and enable the full set of POTS services that are delivered
20、via a V5 LE and AN to be ubiquitously provided in a NGN MG and MGC architecture. NOTE The use of the Call Finished signal is a national option. It is included as part of joint text with ETSI. In normal circumstances, national specific functionality shall be included as a separate package. The use of
21、 Call Finished shall not compromise existing H.248 procedures. 2 References 2.1 Normative references The following ITU-T Recommendations and other references contain provisions which, through reference in this text, constitute provisions of this Recommendation. At the time of publication, the editio
22、ns indicated were valid. All Recommendations and other references are subject to revision; users of this Recommendation are therefore encouraged to investigate the possibility of applying the most recent edition of the Recommendations and other references listed below. A list of the currently valid
23、ITU-T Recommendations is regularly published.
