10、 was prepared by ITU-T Study Group 13 (1997-2000) and approved under the WTSC Resolution 1 procedure on 1 O March 2000. Keywords Access Network, PICS, Service Node,VBS reference points. STD*ITU-T RECMN G.767.3-ENGL 2000 U 48b2571 0688421 229 FOREWORD The International Telecommunication Union (ITU) i
11、s 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 and tariff questions and issuing Recommendations on them with a view to standardizi
12、ng 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 study groups which, in turn, produce Recommendations on these topics. The approval of IT-T Recommendations is covered
13、 by the procedure laid down in WTSC Resolution 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with IS0 and EC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate
14、both a telecommunication administration and a recognized operating agency. 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
15、 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 property, protected by patents, wh
16、ich 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. o ITU 2001 All rights reserved.

30、e been implemented. 3.1.2 Protocol Implementation Conformance Statement (PICS): An ICs for an implementation or system claimed to conform to a given protocol specification. 3.1.3 ICs pro forma: Document, in the form of a questionnaire, which when completed for an implementation or system becomes an
31、ICs. 3.1.4 static conformance review: Review of the extent to which the static conformance requirements are met by the Implementation Under Test (IUT), accomplished by comparing the PICS with the static conformance requirements expressed in the relevant standard(s) (see 71 apply: ISO/IEC9646-1 7 ).

37、fies the physical, procedural and protocol requirements for interfaces at the VB5.2 reference point between an Access Network (AN) and a Service Node (SN). The VB5.2 reference point provides flexible (provisioned) Virtual Path Link (VPL) allocation and flexible (provisioned) Virtual Channel Link (VC

That is the PICS for interfaces at the VB5.2 reference point comprise the PICS defined for the VB5.1 reference point and those which are specific for the B-BCC protocol.
