G.776.1 (1998)/Cor.1 (02/2007) i ITU-T Recommendation G.776.1 Managed objects for signal processing network elements Corrigendum 1 Summary ITU-T Recommendation G.776.1 identifies the information model for the operations and management of S
9、ignal Processing Network Elements (SPNE). Corrigendum 1 contains corrections to be incorporated within a number of data files in G.776.1 Annex A (10/1998), which are used by developers when implementing a TMN. The changes include issues identified in the G.776.1 Implementors Guide (06/1999) and corr
10、ection to errors discovered by the ITU-T SG 17 ASN.1 Project when compiling the respective ASN.1 modules. Source Corrigendum 1 to ITU-T Recommendation G.776.1 (1998) was approved on 13 February 2007 by ITU-T Study Group 16 (2005-2008) under the ITU-T Recommendation A.8 procedure. ii ITU-T Rec. G.776
11、.1 (1998)/Cor.1 (02/2007) 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 responsible for studying technical, operating
12、 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 ITU-T study groups which, in turn, produc
13、e 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 collaborative basis with ISO and IEC. NOTE In this
14、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 mandatory provisions (to ensure e.g. intero
15、perability 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 use of such words does not suggest tha
16、t 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 no position concerning the evidence, v
17、alidity 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 property, protected by patents, which may be r
18、equired to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database at http:/www.itu.int/ITU-T/ipr/.

G.776.1 (1998)/Cor.1 (02/2007) 1 ITU-T Recommendation G.776.1 Managed objects for signal processing network elements Corrigendum 1 1 Scope This Recommendation provides the necessary information required for controlling Signal Processing Network Elements (SPNE) from a Telecommunications Man
21、agement Network (TMN). SPNEs as used in this Recommendation include echo cancellers, transcoders, circuit multiplication systems, and signal/service processing systems. Information in this Recommendation is based on actual and planned equipment installed (or to be installed) in todays Public Switche
22、d Telephone Networks. It is important to also note that this Recommendation does not specify functionality or performance for any particular implementation of an SPNE. The criteria contained herein are intended to only reflect the collective universe of options and features for the particular SPNE c
23、lass. 2 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 editions indicated were valid. All Recommendations and other references are subject to r
24、evision; 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.
