9、BJECTS FOR SIGNAL PROCESSING NETWORK ELEMENTS Summary This Recommendation identifies the information model for the operations and management of Signal Processing Network Elements (SPNE). Source ITU-T Recommendation G.776.1 was prepared by ITU-T Study Group 15 (1997-2000) and was approved under the W
10、TSC Resolution No. 1 procedure on the 23rd of October 1998. Recommendation G.776.1 (10/98) 1 STDmITU-T RECMN G.77b.L-ENGL 1998 M 48b2571 Ob54997 O4 FOREWORD ITU (International Telecommunication Union) is the United Nations Specialized Agency in the field of telecommunications. The ITU Telecommunicat
11、ion Standardization Sector (ITU-T) is a permanent organ of the ITU. The 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 Co
12、nference (WTSC), which meets every four years, establishes the topics for study by the ITU-T Study 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
13、 areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with IS0 and IEC. NOTE In this Recommendation the term recognized operating agency (ROA) includes any individual, company, corporation or governmental organization that op
14、erates a public correspondence service. The terms Administration, ROA and public correspondence are defined in the Constitution of the ITU (Geneva, 1992). INTELLECTUAL PROPERTY RIGHTS The ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve th
15、e 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 Recommendation development process. As of the date of approval of this Recomm
16、endation, 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 information and are therefore strongly urged to consult the TSB patent database

19、n provides the necessary information required for controlling Signal Processing Network Elements (SPNE) from a Telecommunications Management Network (TMN). SPNEs as used in this Recommendation include echo cancellers, transcoders, circuit multiplication systems, and signalhervice processing systems.
20、 Information in this Recommendation is based on actual and planned equipment installed (or to be installed) in todays Public Switched Telephone Networks. It is important to also note that this Recommendation does not specify functionality or performance for any particular implementation of an SPNE.
21、The criteria contained herein are intended to only reflect the collective universe of options and features for the particular SPNE class. 2 References The following Recommendations and other references contain provisions which, through reference in this text, constitute provisions of this Recommenda
22、tion. At the time of publication, the editions indicated were valid.
